[0036] like Figures 1 to 8 As shown, the present invention provides a planetary reducer performance testing device, comprising: a machine base 1, a protective cover 2 fixedly installed on the machine base 1, a testing mechanism 3 for performing performance testing on the reducer, a fixing mechanism 4 for fixing the reducer, and a cooling mechanism 5 for cooling the reducer during the testing process.

[0037] The fixing mechanism 4 includes: a clamping plate 41, the clamping side of which is arc-shaped; a driving component 42 for moving the clamping plate 41; a guiding component 43 for guiding the movement of the clamping plate 41; and a positioning component 44 for positioning the reducer. The driving component 42 includes: a mounting box 421 fixedly mounted on the machine base 1; a mounting opening on the mounting box 421; a movable plate 422 movably mounted in the mounting opening; a rolling element 423 rotatably mounted on the movable plate 422; a mounting plate 424 slidably mounted in the mounting box 421; a power source 425 for moving the mounting plate 424, which is fixedly connected to the mounting box 421; and a pressing plate 426 fixedly mounted on the mounting plate 424, the pressing plate 426 being inclined on the side that abuts against the rolling element 423. The clamping plate 41 is fixedly connected to the movable plate 422.

[0038] When the speed reducer is placed on the positioning assembly 44, the power source 425 is started to drive the mounting plate 424 to move upward, the mounting plate 424 drives the extrusion plate 426 to move upward, and the abutting side of the extrusion plate 426 and the rolling part 423 is inclined, so that when the extrusion plate 426 moves upward, the rolling part 423 is extruded, so that the rolling part 423 slides along the inclined surface of the extrusion plate 426, and then under the limiting and guiding effect of the guide assembly 43, the two movable plates 422 are driven to approach each other, the two movable plates 422 drive the adjacent clamping plates 41 to approach each other, and when the arc surfaces of the two clamping plates 41 completely abut against the shell of the speed reducer, the clamping and fixing of the speed reducer are realized, the displacement of the injection molding part during performance testing of the speed reducer is avoided, and the stability of the speed reducer during testing is improved.

[0039] When the speed reducer is placed on the positioning assembly 44, the power source 425 is started to drive the mounting plate 424 to move upward, the mounting plate 424 drives the extrusion plate 426 to move upward, and the abutting side of the extrusion plate 426 and the rolling part 423 is inclined, so that when the extrusion plate 426 moves upward, the rolling part 423 is extruded, so that the rolling part 423 slides along the inclined surface of the extrusion plate 426, and then under the limiting and guiding effect of the guide assembly 43, the two movable plates 422 are driven to approach each other, the two movable plates 422 drive the adjacent clamping plates 41 to approach each other, and when the arc surfaces of the two clamping plates 41 completely abut against the shell of the speed reducer, the clamping and fixing of the speed reducer are realized, the displacement of the injection molding part during performance testing of the speed reducer is avoided, and the stability of the speed reducer during testing is improved.

[0040] The two sides of the mounting plate 424 are fixedly connected with sliding strips, and the inner wall of the mounting box 421 is provided with a guide groove, the sliding strips slide in the guide groove, and when the mounting plate 424 moves, the sliding strips slide in the guide groove, so that the mounting plate 424 is limited and guided, and the stability of the mounting plate 424 during movement is improved.

[0041] When the two clamping plates 41 approach each other, the guide assembly 43 can limit and guide the clamping plates 41, the guide assembly 43 comprises guide rods 431 penetratingly mounted on the movable plates 422 and linkage springs 432 driving the clamping plates 41 to reset, the guide rods 431 are fixedly mounted in the mounting openings, one end of the linkage spring 432 is fixedly connected with the movable plate 422, and the other end of the linkage spring 432 is fixedly connected with the mounting opening, and two guide rods 431 are symmetrically arranged on each movable plate 422, which can avoid the displacement of the clamping plates 41 during movement, make the clamping plates 41 move along the axial direction of the guide rods 431, has the limiting and guiding effect, and can uniformly support the two sides of the clamping plates 41, so that the stability of the clamping plates 41 during movement is high.

[0042] During the process that the two clamping plates 41 approach each other, the movable plate 422 drives the adjacent linkage spring 432 to stretch, so that the clamping plate 41 generates a pulling force opposite to the moving direction of the clamping plate 41, when the arc surfaces of the two clamping plates 41 completely abut against the shell of the speed reducer, the clamping and fixing of the speed reducer are realized, the displacement of the injection molding part during performance testing of the speed reducer is avoided, and the stability of the speed reducer during testing is improved.

[0043] When the performance test of the speed reducer is completed, the power source 425 drives the mounting plate 424 to move downward, and drives the extrusion plate 426 to move downward, at this time, the clamping plate 41 can be reset through the elastic force of the linkage spring 432, so as to prepare for subsequent use.

[0044] In the application, the power source 425, the mounting plate 424, the extrusion plate 426, the movable plate 422, the clamping plate 41 and the guide assembly 43 are matched with each other, so that the automatic clamping and fixing or automatic releasing of the speed reducer are realized, and the speed reducer is convenient to replace and test, the test efficiency is improved, and the problem that the existing test device adopts the method of tightening the peripheral screws of the shell to fix the speed reducer is solved, the fixing method needs to repeatedly assemble and disassemble multiple screws, which is very cumbersome, and when the number of tested speed reducers is large, if the assembly and disassembly are repeatedly performed, a large amount of manpower and material resources will be consumed, and the work efficiency is low.

[0045] It is supplemented here that the power source 425 is preferably a pneumatic cylinder, and the rolling element 423 is preferably a bull eye ball.

[0046] The positioning assembly 44 comprises a positioning plate 441 fixedly installed on the mounting box 421, a cavity opened on the positioning plate 441, a through hole 442 in communication with the cavity, a sleeve 443 fixedly installed on the movable plate 422, a piston 444 slidably installed in the sleeve 443, a fixing rod 445 fixedly installed between the piston 444 and the mounting box 421, and a gas guide pipe 446 in communication with the sleeve 443 and the cavity.

[0047] When the speed reducer is fixed, the speed reducer is first placed on the top of the positioning plate 441, the top of the positioning plate 441 is provided with an arc shape matched with the speed reducer, so that the speed reducer is quickly positioned when fixed, and the speed reducer is prevented from deviating on the top of the positioning plate 441, thereby facilitating subsequent fixing.

[0048] A plurality of through holes 442 are arranged on the positioning plate 441, when the speed reducer is placed on the top of the positioning plate 441, the shell of the speed reducer seals the plurality of through holes 442, when the power source 425 drives the mounting plate 424 to move upward, the two movable plates 422 are driven to move close to each other, the two movable plates 422 drive the adjacent sleeves 443 to move close to each other, the relative movement of the sleeve 443 and the adjacent piston 444 can suck out the air in the cavity of the positioning plate 441, so that negative pressure is generated in the cavity, and the through hole 442 generates suction force on the speed reducer, thereby assisting the fixing of the speed reducer.

[0049] Since the positioning assembly 44 is provided with multiple groups, the through hole 442 has good adsorption effect on the reducer, thereby improving the fixing effect of the reducer, and avoiding the deviation of the reducer on the top of the positioning plate 441 during the fixing process of the reducer, thereby facilitating the subsequent fixing.

[0050] The present application realizes the positioning of the reducer before fixing by the cooperation of the clamping plate 41 and the positioning assembly 44, avoids the deviation of the reducer on the top of the positioning plate 441, thereby facilitating the subsequent fixing, and can fix the reducer from different directions, thereby improving the fixing effect of the reducer and the stability during the performance test of the reducer.

[0051] As a further extension of the present application, the reducer generates a large amount of heat during high-speed operation in the test process, which causes the temperature of the reducer to rise. If the reducer is not cooled, the high temperature may affect the accuracy of the test, thereby affecting the accurate evaluation of the performance parameters of the reducer.

[0052] The cooling mechanism 5 comprises a liquid storage bag body 51 fixedly installed on the movable plate 422, a cooling bag body 53 fixedly installed on the clamping plate 41, and a liquid guide pipe 52 communicating the liquid storage bag body 51 and the cooling bag body 53.

[0053] During the clamping and fixing of the reducer, the two movable plates 422 are close to each other, which drives the compression of the liquid storage bag body 51. The liquid storage bag body 51 stores cooling liquid. When the liquid storage bag body 51 is extruded, the cooling liquid in the liquid storage bag body 51 enters the cooling bag body 53 through the liquid guide pipe 52, so that the cooling bag body 53 expands.

[0054] The cooling bag body 53 is arc-shaped, and the clamping plate 41 is provided with an arc-shaped groove matched with the cooling bag body 53, thereby facilitating the installation of the arc-shaped groove. When the cooling bag body 53 collides, the cooling bag body 53 is tightly attached to the shell of the reducer. At this time, the cooling liquid in the cooling bag body 53 can cool the reducer, so that the reducer can run in a relatively stable temperature range, thereby improving the accuracy and reliability of the test.

[0055] Since the cooling liquid enters the cooling bag body 53 during the clamping of the reducer, the reducer is cooled before the test, so that the high temperature generated during the test of the reducer can be cooled in time, the reducer can be ensured to be in a relatively stable temperature state during the test, thereby helping to eliminate the test error caused by temperature difference, making the test result more accurate and reliable, and by keeping the reducer running in a suitable temperature range, the consistency of the test conditions can be ensured, thereby more accurately evaluating the performance of the reducer.

[0056] In addition, since the shape of the cooling capsule 53 is arranged in an arc shape, and when the cooling capsule 53 collides, the cooling capsule 53 is tightly attached to the shell of the speed reducer, so that the expanded cooling capsule 53 can clamp the speed reducer, and then cooperate with the clamping plate 41, thereby improving the fixing effect of the speed reducer.

[0057] When the performance test of the speed reducer is completed, the power source 425 is started to drive the mounting plate 424 to move downward, and the pressing plate 426 is driven to move downward, at this time, the elastic force of the connecting spring 432 can drive the clamping plate 41 to reset, at the same time, the liquid storage capsule 51 gradually recovers, so that the cooling liquid flows back to the liquid storage capsule 51, and the movable plate 422 is reset, and then the clamping plate 41 is reset.

[0058] In the present application, when the liquid storage capsule 51 is compressed, the cooling liquid can be delivered to the cooling capsule 53 to cool the speed reducer, and when the liquid storage capsule 51 recovers, the cooling liquid flows back to the liquid storage capsule 51 and drives the clamping plate 41 to reset.

[0059] It is supplemented here that the liquid storage capsule 51 is connected with a cold source, and the cooling liquid in the liquid storage capsule 51 can be refrigerated.

The docking assembly 36 is provided with two groups, which are respectively docked on both sides of the speed reducer, and a moving assembly 37 for driving the docking assembly 36 to move in and out of the docking with the speed reducer. The moving assembly 37 is provided with two groups, which respectively drive the mounting frame one 31 and the mounting frame two 32 to move.

[0061] The torque sensor 35 is provided with two groups, and the magnetic powder brake 34 and the motor 33 are all driven through the shaft coupling and the adjacent torque sensor 35.

[0062] The moving assembly 37 comprises: a sliding seat 371 fixedly installed on the mounting frame one 31 and the mounting frame two 32, a sliding rail 372 in sliding connection with the sliding seat 371, and a power source two 373 fixedly installed on the machine table 1. The sliding rail 372 is fixedly installed on the machine table 1. The mounting frame one 31 and the mounting frame two 32 are respectively fixedly connected with the movable end of the adjacent power source two 373.

[0063] When the speed reducer is fixed, the two power sources two 373 are started to drive the mounting frame one 31 and the mounting frame two 32 to move close to each other, thereby driving the two groups of docking assemblies 36 to move close to each other, and making the docking assemblies 36 dock with the speed reducer.

[0064] When the mounting frame one 31 and the mounting frame two 32 move, the sliding seat 371 can slide on the sliding rail 372, and through the cooperation between the sliding seat 371 and the sliding rail 372, the mounting frame one 31 and the mounting frame two 32 can be limited and guided during movement, and the stability of the mounting frame one 31 and the mounting frame two 32 during movement is improved.

[0065] It is supplemented here that the power source two 373 is preferably a cylinder.

[0067] When the two groups of docking assemblies 36 approach each other, the two connecting cylinders 361 are respectively sleeved on the output shaft or the input shaft of the speed reducer, after the two sliding plates 3631 respectively abut against the output shaft or the input shaft of the speed reducer, the sliding plates 3631 no longer move, the connecting cylinder 361 drives the linkage rod 3635 to continue to move, the linkage rod 3635 drives the linkage block 3636 and the linkage plate 362 to continue to move, and since the abutting sides of the extrusion block 3632 and the linkage block 3636 are both inclined, the linkage block 3636 is extruded when moving, the extrusion block 3632 drives the linkage rod 3635 to move, and the linkage rod 3635 drives the linkage plate 362 to move.

[0068] Through the linkage rod 3635 driving the limiting block 3637 to slide in the limiting groove 3638, and the limiting of the limiting opening 3634 to the linkage rod 3635, the plurality of linkage rods 3635 approach each other, so as to drive the plurality of linkage plates 362 to approach each other, through the mutual approach of the plurality of linkage plates 362, the output shaft or the input shaft of the speed reducer can be clamped and fixed in multiple directions, so as to improve the fixing effect of the output shaft or the input shaft of the speed reducer, and further improve the stability of the docking between the test mechanism 3 and the speed reducer.

[0069] When the testing mechanism 3 is connected with the speed reducer in the application, only the mobile assembly 37 is started to drive the docking assembly 36 to approach the speed reducer, so that the docking assembly 36 is automatically fixed with the output shaft or the input shaft of the speed reducer, manual docking and fixing are not needed, and the working efficiency is improved.

[0070] The reset member 3633 comprises a sliding block 36331 fixedly installed on the sliding plate 3631, a sliding groove opened in the connecting barrel 361, and a reset spring 36332 for driving the sliding plate 3631 to reset; the sliding block 36331 is slidingly installed in the sliding groove; one end of the reset spring 36332 is fixedly connected with the sliding block 36331, and the other end of the reset spring 36332 is fixedly connected with the sliding groove.
