Description

Weighing apparatus four angle testers

Technical field

The present invention relates to a kind of tester, particularly a kind of weighing apparatus unbalance loading when test tester that is specifically designed to.

Background technology

In the Installation and Debugging process of weighing apparatus, requirement according to inspection procedure, need carry out unbalance loading test to 4 on the weighing apparatus, just successively counterweight is placed in the zone that area approximates weighing apparatus loading end 1/4 weighing apparatus is detected, thereby whether the error of observation weighing apparatus is in allowed band.At present for the loading of counterweight on weighing apparatus, generally only rely on manual the loading, deviation often appears in putting position, thereby have influence on accuracy of detection to weighing apparatus, and workman's manual operations, need the frequent counterweight of changing that weighing apparatus is added unloading, make working strength of workers increase, and efficient is very low.

Summary of the invention

At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provides a kind of tester that can load weighing apparatus automatically, realizes the robotization of loading, increases work efficiency, reduces working strength.

For solving the problems of the technologies described above, the present invention adopts following technical scheme:

A kind of weighing apparatus four angle testers, it comprises a support, described support is provided with a square table top, respectively be provided with a counterweight charging crane on four angles of described table top, described counterweight charging crane comprises that a weight group, a counterweight mobile device and a counterweight add discharge mechanism, described counterweight adds discharge mechanism and is connected with described weight group, and described counterweight mobile device adds discharge mechanism with described counterweight and is connected, and described counterweight adds discharge mechanism and is connected with a control system.

Preferably, described counterweight mobile device comprises handwheel, screw mandrel, screw, and described handwheel is connected with described screw mandrel, and described screw is positioned on the screw mandrel, and described screw adds discharge mechanism with described counterweight and is connected.

Preferably, described counterweight adds discharge mechanism and comprises leading screw, slide block, synchronous band, belt wheel, linear electric motors, and described linear electric motors are connected with described belt wheel by being with synchronously, and described belt wheel is connected with described leading screw, described slide block is positioned on the described leading screw, and described slide block is connected with described weight group.

Preferably, described counterweight adds discharge mechanism and also comprises a rope sensor, and described rope sensor is connected with described control system.

Preferably, described weight group is in series to the level Four counterweight step by step by one.

Technique scheme has following beneficial effect: these weighing apparatus four angle testers at first accurately navigate to counterweight on the weighing apparatus load(ing) point counterweight by the counterweight mobile device in use, add discharge mechanism by counterweight then the counterweight in the weight group is added the unloading action on weighing apparatus, weighing apparatus is carried out the unbalance loading test.These weighing apparatus four angle testers are compared with existing load mode, have simple in structurely, easy and simple to handle, locate accurate characteristics, have reduced labour intensity, and can be used for the unbalance loading and the repeated experiment of multiple weighing apparatus.

Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of instructions, below with preferred embodiment of the present invention and conjunction with figs. describe in detail as after.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.

Description of drawings

Fig. 1 is the front view of the embodiment of the invention.

Fig. 2 is the vertical view of the embodiment of the invention.

Embodiment

Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.

As Fig. 1, shown in 2, these weighing apparatus four angle testers comprise asupport 3,frame 3 usefulness square steel are welded, fix on the ground with foot bolt,frame 3 tops connectsquare table top 5 with bolt and form framework, respectively be provided with a counterweight charging crane on four angles oftable top 5, the counterweight charging crane comprises aweight group 2, an one counterweightmobile device 4 and a counterweight add discharge mechanism 6, counterweightmobile device 4 and counterweight add discharge mechanism 6 and are installed on the work top respectively, totally four groups, diagonal line alongtable top 5 is installed, and installs relatively in twos, and counterweightmobile device 4 sides have scale,weight group 2 is positioned in the framework, andweight group 2 is in series to the level Four counterweight step by step by one.First, second level is the 1Kg counterweight, and the third level is the 3Kg counterweight, and the fourth stage is the 5Kg counterweight, can satisfy different loading requirements.

The counterweight mobile device compriseshandwheel 41, screw mandrel, screw, and handwheel is connected with screw mandrel, and screw is positioned on the screw mandrel, and screw adds discharge mechanism with counterweight and is connected.Counterweight adds discharge mechanism and comprises leading screw, slide block, synchronous band, belt wheel, linear electric motors, and linear electric motors are connected with belt wheel by being with synchronously, and belt wheel is connected with leading screw, and slide block is positioned on the leading screw, and slide block is connected with weight group.Counterweight adds discharge mechanism and also comprises a rope sensor, and rope sensor and linear electric motors are connected with a control system.

These weighing apparatus four angle testers before the loading, at first according to the size of weighing apparatus, accurately navigate toweight group 2 on the weighing apparatus load(ing) point by the handwheel on the counterweightmobile device 4 41 in use.Adding when unloading then, starting counterweight by control system and add linear electric motors on the discharge mechanism 6, transferred torque on the leading screw by the linear motor driving reduction gear, leading screwdrives weight group 2 and adds unloading.The rope sensor that counterweight adds discharge mechanism 6 outfits feeds back to control system with the counterweight loaded condition, and the counterweight that control system is controlled in theweight group 2 as required adds unloading separately or simultaneously, also can add unloading as required step by step.

These weighing apparatus four angle testers are compared with existing load mode, have simple in structurely, easy and simple to handle, locate accurate characteristics, have reduced labour intensity, and can be used for the unbalance loading and the repeated experiment of multiple weighing apparatus.

More than a kind of weighing apparatus four angle testers that the embodiment of the invention provided are described in detail; for one of ordinary skill in the art; thought according to the embodiment of the invention; part in specific embodiments and applications all can change; therefore this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
