Description

Technical Field

[0001] The invention relates to the field of speed reducer testing, and in particular to a speed reducer torque testing device for pharmaceutical equipment. Background Art

[0002] The reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. For reducers with high precision requirements, their idling torque needs to be tested before leaving the factory to ensure that the idling torque of the reducer is less than the rated output torque of the motor adapted to it, and to detect whether there is a stuck point when the reducer is running, that is, whether the gear meshing is good;

[0003] Patent: CN219608414U relates to the field of torque testing technology, and in particular to a reducer torque testing device. The utility model provides a reducer torque testing device that can adapt to reducers of different models and improve adaptability.

For this reason, we propose a reducer torque test device for pharmaceutical equipment. Summary of the invention

[0008] A driving mechanism is arranged on the right side of the upper surface of the base;

[0009] The clamping mechanism includes a base plate, both ends of the base plate are fixedly connected to a mounting seat, the inner side of the mounting seat is rotatably connected to a turntable via a rotating shaft, opposite sides of two adjacent turntables are provided with a coupling seat, and the opposite sides of the two coupling seats are fixedly connected to a pressure push block, the end of the pressure push block away from the coupling seat passes through the turntable and is slidably connected to the turntable, a plurality of connecting plates are fixedly connected to the side of the turntable close to the coupling seat, and a wedge-shaped extrusion block is fixedly connected to the end of the connecting plate away from the turntable, a plurality of through-type positioning holes are opened on the inner side of the coupling seat, a positioning column is slidably connected to the inside of the positioning hole, and a pressure plate is fixedly connected to the end of the positioning column away from the center of the coupling seat.

[0028] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 4 and Figure 5 As shown, a torque test device for a reducer used in pharmaceutical equipment is provided, comprising a base 1, a notch 2 is provided on the upper surface of the base 1, and a test seat 3 is slidably connected to the inner side of the notch 2;

[0031] A slide groove 7 is provided on both sides of the inside of the notch 2, and a slider 8 is slidably connected to the inner side of the slide groove 7, and the opposite sides of the two sliders 8 are fixedly connected to the two sides of the test seat 3 respectively;

[0032] The test seat 3 can slide along the inside of the notch 2 through the provided slide groove 7 and the slider 8, so as to facilitate the control of the moving position of the clamping mechanism 4. Then, after one group of clamping mechanisms 4 clamps the reducer for testing, the test seat 3 can be pushed to move, and the reducer clamped by another group of clamping mechanisms 4 can be controlled to move to the test position for testing. At the same time, it is convenient to disassemble the reducer after the test is completed, and install and put the next reducer;

[0033] The upper surface of the test seat 3 is provided with two slide grooves 2 9, the interior of the slide groove 2 9 is fixedly connected with a slide rod 10, the outer wall of the slide rod 10 is slidably connected with a slider 2 11, a plurality of springs 4 12 are fixedly connected between the slider 2 11 and the slide groove 2 9, and the upper surface of the slider 2 11 is fixedly connected with the lower surface of the bottom plate 401;

[0034] When the driving mechanism 6 is driven, the clamping mechanism 4 can be controlled to move to the left and dock with the testing mechanism 5, so as to facilitate the testing of the reducer on the clamping mechanism 4. At this time, the test seat 3 can be restricted from sliding along the recess 2, thereby avoiding the problem of the reducer position being offset during the test process.

[0035] like Figure 2 and Figure 3 As shown, a clamping mechanism 4 is provided at the front and rear of the upper surface of the test seat 3;

[0036] The clamping mechanism 4 includes a bottom plate 401, both ends of the bottom plate 401 are fixedly connected with a mounting seat 402, the inner side of the mounting seat 402 is rotatably connected with a turntable 403 through a rotating shaft, the opposite sides of two adjacent turntables 403 are provided with a coupling seat 404, and the opposite sides of the two coupling seats 404 are fixedly connected with a pressure push block 405, the end of the pressure push block 405 away from the coupling seat 404 penetrates the turntable 403 and is slidably connected to the turntable 403, a side of the turntable 403 close to the coupling seat 404 is fixedly connected with a plurality of connecting plates 406, and the end of the connecting plate 406 away from the turntable 403 is fixedly connected with a wedge-shaped extrusion block 407, and the inner side of the coupling seat 404 is provided with a plurality of through-type positioning holes 408, and the interior of the positioning hole 408 is slidably connected with a positioning column 409, and the end of the positioning column 409 away from the center of the coupling seat 404 is fixedly connected with a pressure plate 410;

[0037] The coupling seat 404 is used to engage with the shaft of the reducer.

At this time, the positioning column 409 will shrink toward the inside of the coupling seat 404 and abut the shaft of the reducer, further ensuring that the coupling seat 404 is firmly connected to the reducer, so that the drive motor 604 can drive the reducer to drive the test.
