Specific embodiment
Below, with reference to accompanying drawing and specific embodiment, the utility model is described further：
As shown in figures 1-4, a kind of mash welder, including mash welder main body (not shown), also including electrode 1, the and of elastic component 2Holder 3, electrode 1 is connected to mash welder main body, and holder 3 is fixedly connected on mash welder main body, and holder 3 includes hollow chamberRoom (not shown), one end of elastic component 2 is connected with the insulation of electrode 1, and the other end is connected to holder 3, and electrode 1 is from top to bottom successivelySlidably it is connected to elastic component 2 and chamber.
Because holder 3 is fixedly connected on mash welder main body, therefore holder 3 will not fall because of the effect of gravity；Because electrode 1 is connected to mash welder main body, electrode 1 can slidably be connected to elastic component 2 and chamber, not have successively from top to bottomWhen being subjected to, due to the effect of elastic component 2, electrode 1 does not pass through the sky of holder 3 towards one end of holder 3Chamber, therefore will not be electrically connected with pin 7, even if pin 7 is installed to holder 3 by workman, weld job will not be also carried out,Can prevent workman from getting an electric shock；When needing to be subjected to, pin 7 is installed on holder 3, and operative's electrode 1 makesElectrode 1 is moved downward and through cavity, contacted with pin 7, and now elastic component 2 is compressed；Due to electrode 1 and mash welder main bodyElectrical connection, therefore the conduction of pin 7 when after electrode 1 being contacted with pin 7, so as to carry out weld job, specific bit are welded to by pin 7Put；After the completion of welding, workman stops operation, and due to the effect of elastic component 2, original position is returned to moving electrode 1, so followsRing is reciprocal.Meanwhile, pin 7 is clamped by holder 3, spot welding of the pin 7 on mash welder is realized, without using welding gun, reduceCost, also reduces the labour intensity of workman；Due to the effect of elastic component 2, electrode 1 will not connect with pin 7 when installing pin 7Touch, and staff install pin when will not directly contact electrode 1, effectively reduce workman's Danger Electric shock risk, it is safer.
As depicted in figs. 1 and 2, the mash welder also includes the first sleeve 4, second sleeve 5 and fixture 6, and electrode 1 includes theOne flange 11, holder 3 is fixedly connected on mash welder main body by fixture 6, and is preferably welded to connect；Electrode 1 from upper andUnder be slidably connected to the first sleeve 4, elastic component 2, second sleeve 5 and chamber successively, holder 3 includes the second flange 31, folderGripping member 3 is nested in second sleeve 5 towards one end of the first flange 11, and the second flange 31 is abutted with second sleeve 5, first setCylinder 4 is abutted with the first flange 11, and one end of elastic component 2 is abutted with the first sleeve 4, and the other end and the second sleeve 5 of elastic component 2 are supportedConnect；When not being subjected to, because the first sleeve 4 is abutted with the first flange 11, in the presence of elastic component 2, electrode 1The cavity of holder 3 is not passed through towards one end of holder 3, the pin 7 that will not be clamped with clamped part 3 is contacted, therefore notCan be electrically connected with pin 7；When needing to be subjected to, because the first sleeve 4 is abutted with the first flange 11, with electrode 1Move downward, the first flange 11 drives the first sleeve 4 to move downward, and now elastic component 2 is compressed, after electrode 1 is contacted with pin 7When pin 7 it is conductive, so as to carry out weld job, pin 7 is welded to specified location；After the completion of welding, workman stops operation, byIn the effect of elastic component 2, the first sleeve 4 returns to original position, and then via the first flange 11 with the overall recovery of moving electrode 1To original position, so move in circles.
As shown in Figure 3 and Figure 4, holder 3 includes several elastic clips 32, preferably eight, the edge of each elastic clip 32The circumference of holder 3 is equidistantly distributed, and makes the uniform force of pin 7 when pin 7 is clamped, to carry out weld job.
Preferably, the extension line of each elastic clip 32 intersects with the central axis of holder 3, i.e., under each elastic clip 32Portion inclines to the central axis of holder 3, in order to clamp pin 7；There is gap 33 between adjacent elastic clip 32, andThe gap 33 is gradually reduced from top to bottom, therefore the width of each elastic clip 32 gradually increases from top to bottom, when pin 7 is clampedWhen, the gap 33 between the bottom of each elastic clip 32 is gradually reduced and even abuts, therefore can keep certain clamping force, willPin 7 is accurately positioned, to improve welding precision.
As shown in figure 4, the inwall of each elastic clip 32 is convexly equipped with raised 34, when pin 7 is clamped by each elastic clip 32,The lower end of each projection 34 abuts with pin 7, improves the positioning precision of pin 7；And electrode 1 will not be touched when moving downwardEach projection 34, does not interfere with welding.
As depicted in figs. 1 and 2, the first sleeve 4 include the first cylinder 41 and along the first cylinder 41 radially extend it is the 3rd convexEdge 42, third lip 42 is abutted with the first flange 11；Second sleeve 5 includes the second cylinder 51 and is radially extended along the second cylinder 51The 4th flange 52, the 4th flange 52 abuts with the second flange 31；Elastic component 2 is spring, and one end of spring is riveted on firstSleeve 4, the other end is riveted on second sleeve 5, for providing the power that electrode 1 resets；When workman stops welding operation,Originally the spring for being compressed restores to the original state, because the 4th flange 52 of second sleeve 5 is abutted with clamping element all the time, therefore second set5 positions of cylinder are constant, and spring promotes the first sleeve 4 to return to original position, simultaneously because the third lip 42 of the first sleeve 4 and electricityFirst flange 11 of pole 1 is abutted, therefore finally electrode 1 is returned to original position.
Preferably, the internal diameter of spring is equal to the external diameter of the first cylinder 41 and the second cylinder 51, so as to preferably with each sleeveCoordinate, prevent it is larger rock, while the outer wall of the first cylinder 41 and the second cylinder 51 scribbles lubricating oil, can reduce and rubWipe and noise can be reduced.
Preferably, electrode 1 and holder 3 are made by red metal, with good electric conductivity, are convenient for weld job.
Preferably, the first sleeve 4 and second sleeve 5 are made by insulating ceramics, with good insulating properties, to prevent workPeople's accidental shock.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other variousIt is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claimWithin the scope of.
