Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described further:
In describing the invention, it should be noted that, orientation or the position relationship of the instruction such as term " " center ", " on ", D score, "left", "right", " vertically ", " level ", " interior ", " outward " be based on orientation shown in the drawings or position relationship; be for only for ease of the description present invention and simplifying and describe; rather than instruction or imply indication position or element must have specific orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
In describing the invention, it should be noted that unless otherwise clearly defined and limited, term " is installed ", " being connected ", " connection " should be interpreted broadly, and connects for example, it may be fixing, it is also possible to be to removably connect, or be integrally connected；Can be to be mechanically connected, it is also possible to be electrical connection；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition can be regarded and understand above-mentioned term concrete meaning in the present invention.
nullAs depicted in figs. 1 and 2，A kind of detection tool of machine tooling clamping device，Including upper tool 1、Detection device for elasticity 2 and lower tool 3，Workpiece 4 to be detected is annular or the difformity such as square，The detection applicable difform workpiece 4 of tool，Upper tool 1 and lower tool 3 inner side in opposite directions is provided with the step of socket workpiece 4，Step can be square or circular，The surface choosing lower tool 3 is clamping face，Upper tool 1 is divided into upper cover 11 and lower cover 12，Detection device for elasticity 2 is installed on upper cover 11 and the interior intracavity of lower cover 12 composition，Detection device for elasticity 2 moves down with upper tool 1，Workpiece 4 is by upper tool 1 and lower tool 3 clamping and positioning，Detection device for elasticity 2 detects workpiece 4, and whether clamping is accurate，Detection device for elasticity 2 is at least provided with 1，It is preferably 5，Detection device for elasticity 2 circumference equal dividing cloth is arranged on tool 1 inner chamber，Detection device for elasticity 2 can increase according to actual needs.
As shown in Figure 3, the embodiment one of elastic force apparatus: detection device for elasticity 2 includes 21,2 spring needles 23 of probe and fixed block 22, the threaded fixed block of probe 21 22, it is internal that fixed block 22 is installed on tool 1, spring needle 23 is installed in fixed block 22 left and right sides, and spring needle 23 can commercially be chosen, and spring needle 23 is preferably 2, can increase and decrease according to actual needs, spring needle 23 one end contacts with fixed block 22；The other end contacts with upper tool 1 inner cavity top, and probe 21 is provided with detection scale, and probe 21 afterbody stretches out bottom upper tool 1.The workpiece 4 of annular is sleeved on the upper location of lower tool 3 in advance, upper tool 1 moves down clamping workpiece 4, goes up tool 1 simultaneously and drives probe 21 to contact with lower tool 3 clamping face, if workpiece 4 clamping is bad by spring needle 23, it is internal that probe 21 stress stretches into tool 1, thus judges that workpiece 4 is undesirable.
As shown in Figure 4, the embodiment two of elastic force apparatus: detection device for elasticity 2 includes 21,2 springs 24 of probe and fixed block 22, the threaded fixed block of probe 21 22, it is internal that fixed block 22 is installed on tool 1, spring 24 is installed in fixed block 22 left and right sides, spring 24 preferably has 2, can increase and decrease according to actual needs, and spring 24 one end contacts with fixed block 22；The other end contacts with upper tool 1 inner cavity top, and probe 21 is provided with detection scale, and probe 21 afterbody stretches out bottom upper tool 1.The workpiece 4 of annular is sleeved on lower tool 3 location in advance, upper tool 1 moves down clamping workpiece 4, goes up tool 1 simultaneously and drives probe 21 to contact with the clamping face of lower tool 3, if workpiece 4 clamping is bad by spring 24, it is internal that probe 21 stress stretches into tool 1, thus judges that workpiece 4 is undesirable.
As shown in Figure 5, the embodiment three of elastic force apparatus: detection device for elasticity 2 includes 21,1 spring 25 of probe and fixed block 22, the threaded fixed block of probe 21 22, it is internal that fixed block 22 is installed on tool 1, spring 25 has 1 and is set in below probe 21, and spring 25 one end is touched with fixed block 22 bottom connection, and the other end contacts with upper tool 1 intracavity bottom, probe 21 is provided with detection scale, and probe 21 afterbody stretches out bottom upper tool 1.The workpiece 4 of annular is sleeved on the step cutting pattern of lower tool 3 location in advance, upper tool 1 moves down clamping workpiece 4, and probe 21 contacts with the clamping face of lower tool 3, if workpiece 4 clamping is bad, it is internal that probe 21 stress stretches into tool 1, thus judges that workpiece 4 is undesirable.
Testing result can be observed more intuitively for the ease of user, tool also includes the judgment means that testing result carries out intuitive judgment, judgment means includes wire, power supply and attention device, attention device is LED or buzzer or the built-in alarm module of lathe, attention device electrically connects probe by wire, when workpiece 4 clamping is normal, behind lower tool 3 surface of probe contact, power drives LED or buzzer send alarm, visual cues user product can normally use, or the built-in alarm module of lathe reminds user product normally to use；When workpiece 4 clamping abnormal or oversize time, probe can not contact with lower tool 3 clamping face, and attention device is failure to actuate, and visual cues user product is bad.
As shown in Figure 6, detection device for elasticity 2 is also mountable to lower tool 3, and the ring limit that probe 25 stretches out with workpiece 4 from lower tool 3 top contacts.It addition, as it is shown in fig. 7, detection device for elasticity 2 also can be simultaneously attached in tool 1 and lower tool 3, whether clamping is bad for detection workpiece together.As shown in Figure 8, detection tool realizes linkage by microswitch 5 with lathe, and after taking off detection tool, detection tool no longer compresses microswitch 5, and lathe can not start, and prevents from starting suddenly because of lathe causing processing accident；After detection tool is loaded onto, detection tool compresses microswitch 5, and lathe can normally start.
The operation principle of the present invention: illustrate as a example by detecting the workpiece 4 that tolerance is ± 0.05mm, first take a standard qualified workpiece 4 as standard, pre-installation is positioned at the step cutting pattern of lower tool 3, upper tool 1 moves down and contacts with workpiece 4, regulation probe 21 stretches out the length of lower casing 12, probe 21 is made to contact with the clamping face of lower tool 3, attention device will send signal, now, probe 21 detects benchmark exactly to the distance of lower tool 3, when workpiece 4 clamping to be detected not in place so that exceeding the margin of tolerance time, probe 21 moves down and can not contact with lower tool 3, attention device does not works, judge that workpiece 4 is too high；If it is too low to detect workpiece 4, probe 21 can be turned down 0.05mm, Cleaning Principle is too high similar with detection workpiece 4.It addition, upper tool 1 can use the power source such as cylinder or Magnet to drive it to move down, it is ensured that move down and can quick and precisely clamp workpiece 4 every time.
Above content is to combine concrete preferred implementation further description made for the present invention; it cannot be assumed that the present invention be embodied as be confined to these explanations; for general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
