DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0035] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0036] like Figures 1 to 8 As shown, a planetary reducer performance testing device of the present invention includes: a machine platform 1, a protective cover 2 fixedly installed on the machine platform 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 test process.

[0037] The fixing mechanism 4 includes: a clamping plate 41, the clamping side of the clamping plate 41 is arranged in an arc shape, a driving component 42 that drives the clamping plate 41 to move, a guiding component 43 that guides the clamping plate 41 when it moves, and a positioning component 44 that positions the reducer; the driving component 42 includes: a mounting box 421 fixedly mounted on the machine 1, a mounting opening opened 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, and a power source 425 that drives the mounting plate 424 to move, the power source 425 is fixedly connected to the mounting box 421, and a squeezing plate 426 fixedly mounted on the mounting plate 424, and the abutting side of the squeezing plate 426 against the rolling element 423 is inclined; the clamping plate 41 is fixedly connected to the movable plate 422.

[0038] When the reducer is placed on the positioning assembly 44, the mounting plate 424 can be driven to move upward by starting the power source 425, and the mounting plate 424 drives the extrusion plate 426 to move upward. Since the abutting side of the extrusion plate 426 and the rolling element 423 is inclined, when the extrusion plate 426 moves upward, the rolling element 423 is squeezed, so that the rolling element 423 slides along the inclined surface of the extrusion plate 426, and then under the action of the limiting guide of the guide assembly 43, the two movable plates 422 can be driven to approach each other, and the two movable plates 422 drive the adjacent clamping plates 41 to approach each other. When the arc-shaped surfaces of the two clamping plates 41 are completely abutted against the outer shell of the reducer, the reducer is clamped and fixed, thereby avoiding displacement of the injection molded parts of the reducer during performance testing and improving the stability of the reducer during testing.

[0039] After the speed reducer is tested, the power source 1 425 is started to drive the mounting plate 424 to move downward, thereby moving the two clamping plates 41 away from each other, so that the speed reducer can be disassembled easily.

[0040] Slide bars are fixedly connected to both sides of the mounting plate 424, and guide grooves are provided on the inner wall of the mounting box 421. The slide bars slide in the guide grooves. When the mounting plate 424 moves, the slide bars can be driven to slide in the guide grooves, thereby limiting and guiding the mounting plate 424 and improving the stability of the mounting plate 424 when moving.

[0041] When the two clamping plates 41 approach each other, the clamping plates 41 can be limited and guided by the guide assembly 43, and the guide assembly 43 includes: a guide rod 431 installed through the movable plate 422, and a linkage spring 432 for driving the clamping plate 41 to return to its original position; the guide rod 431 is fixedly installed in the installation opening; one end of the linkage spring 432 is fixedly connected to the movable plate 422, and the other end of the linkage spring 432 is fixedly connected to the installation opening; two guide rods 431 are symmetrically arranged on each movable plate 422, on the one hand, the displacement of the clamping plate 41 is avoided when the clamping plate 41 moves, so that the clamping plate 41 moves along the axial direction of the guide rod 431, which plays a role of limiting and guiding, and on the other hand, it can evenly support the two sides of the clamping plate 41, so that the clamping plate 41 has high stability when moving.

[0042] In the process of the two clamping plates 41 approaching each other, the movable plate 422 drives the adjacent linkage spring 432 to stretch, thereby generating a pulling force on the clamping plate 41 opposite to the moving direction of the clamping plate 41. When the arc-shaped surfaces of the two clamping plates 41 are completely in contact with the outer shell of the reducer, the reducer is clamped and fixed, thereby avoiding displacement of the injection molded parts of the reducer during performance testing and improving the stability of the reducer during testing.

[0043] When the reducer performance test is completed, the power source 425 is started to drive the mounting plate 424 to move downward, and the extrusion plate 426 to move downward. At this time, the elastic force of the linkage spring 432 can drive the clamping plate 41 to reset, thereby preparing for subsequent use.

[0044] In the present invention, 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 cooperate with each other, thereby realizing rapid automatic clamping and fixing or automatic releasing of the reducer, thereby facilitating replacement and testing of the reducer, improving the test efficiency, and solving the problem that the existing test device uses the method of tightening the outer screws of the shell to fix the reducer. This fixing method requires repeated installation and removal of multiple screws, which is very cumbersome. When there are many reducers to be tested, if such repeated installation and removal are performed, a large amount of manpower and material resources will be consumed, and the work efficiency will be low.

[0045] It is to be added here that the power source 425 is preferably a cylinder; and the rolling element 423 is preferably a bull's eye ball.

[0046] The positioning assembly 44 includes: a positioning plate 441 fixedly mounted on the installation box 421, a cavity opened on the positioning plate 441, a through hole 442 connected to the cavity, a sleeve 443 fixedly mounted on the movable plate 422, a piston 444 slidably mounted in the sleeve 443, a fixing rod 445 fixedly mounted between the piston 444 and the installation box 421, and an air guide tube 446 connecting the sleeve 443 and the cavity.

[0047] When fixing the reducer, first place the reducer on top of the positioning plate 441. Since the top of the positioning plate 441 is an arc-shaped setting that matches the reducer, the reducer can be quickly positioned when fixed, and the reducer can be prevented from offsetting on the top of the positioning plate 441, thereby facilitating subsequent fixation.

[0048] A plurality of through holes 442 are provided on the positioning plate 441. When the reducer is placed on the top of the positioning plate 441, the shell of the 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 approach each other, and the two movable plates 422 drive the adjacent sleeves 443 to approach each other. Through the relative movement of the sleeves 443 and the adjacent pistons 444, the air in the cavity of the positioning plate 441 can be sucked out, thereby generating negative pressure in the cavity, and then the through holes 442 generate suction on the reducer, thereby playing a role in auxiliary fixing of the reducer.

[0049] Since there are multiple groups of positioning components 44, the through hole 442 has a good adsorption effect on the reducer, thereby improving the fixing effect of the reducer and avoiding the reducer from shifting on the top of the positioning plate 441 during the fixing process of the reducer, thereby facilitating subsequent fixation.

[0050] The present invention realizes the positioning of the reducer before fixation through the mutual cooperation of the clamping plate 41 and the positioning assembly 44, thereby preventing the reducer from shifting on the top of the positioning plate 441, thereby facilitating subsequent fixation; on the other hand, the reducer can be fixed from different directions, thereby improving the fixing effect of the reducer and further improving the stability of the reducer during performance testing.

[0051] As a further extension of the present invention, the speed reducer generates a lot of heat when running at high speed during the test, causing the speed reducer temperature to rise. If the speed reducer is not cooled, the high temperature may affect the accuracy of the test, thereby affecting the accurate evaluation of the speed reducer performance parameters.

[0052] The cooling mechanism 5 includes: a liquid storage sac 51 fixedly mounted on the movable plate 422 , a cooling sac 53 fixedly mounted on the clamping plate 41 , and a liquid guide tube 52 connecting the liquid storage sac 51 and the cooling sac 53 .

[0053] When the reducer is clamped and fixed, the two movable plates 422 approach each other, which can drive the liquid storage bladder 51 to be compressed. The liquid storage bladder 51 stores cooling liquid. When the liquid storage bladder 51 is squeezed, the cooling liquid in the liquid storage bladder 51 enters the cooling bladder 53 through the liquid guide tube 52, causing the cooling bladder 53 to expand.

[0054] The cooling bladder 53 is arc-shaped, and an arc-shaped groove matching the cooling bladder 53 is provided on the clamping plate 41, so as to facilitate the installation of the arc-shaped groove. When the cooling bladder 53 collides, the cooling bladder 53 is tightly attached to the outer shell of the reducer. At this time, the reducer can be cooled by the coolant in the cooling bladder 53, so as to keep the reducer running within a relatively stable temperature range, thereby improving the accuracy and reliability of the test.

[0055] Since the coolant enters the cooling bag 53 during the process of clamping 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, which can ensure that the reducer is in a relatively stable temperature state during the test, and thus help to eliminate the test errors caused by temperature differences, making the test results more accurate and reliable, and by keeping the reducer running within an appropriate 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 cooling bladder 53 is arc-shaped and when the cooling bladder 53 collides, it is tightly attached to the outer shell of the reducer, so that the expanded cooling bladder 53 can clamp the reducer, and then cooperate with the clamping plate 41 to improve the fixing effect of the reducer.

[0057] When the reducer performance test is completed, start the power source 425 to drive the mounting plate 424 to move downward, and drive the extrusion plate 426 to move downward. At this time, the elastic force of the linkage spring 432 can drive the clamping plate 41 to reset. At the same time, the liquid storage capsule 51 gradually recovers, so that the coolant flows back into the liquid storage capsule 51. During the recovery process, the liquid storage capsule 51 can drive the movable plate 422 to reset, and then drive the clamping plate 41 to reset.

[0058] When the liquid storage bladder 51 is compressed in the present invention, the coolant can be transported to the cooling bladder 53 to cool the reducer. When the liquid storage bladder 51 is restored, the coolant flows back into the liquid storage bladder 51 and can drive the clamping plate 41 to reset.

[0059] It is to be supplemented here that the liquid storage sac 51 is connected to an external cold source so as to cool the coolant in the liquid storage sac 51 .

[0060] The testing mechanism 3 includes: a mounting frame 1 31, a mounting frame 2 32, a motor 33 fixedly mounted on the mounting frame 1 31, a magnetic powder brake 34 fixedly mounted on the mounting frame 2 32, a torque sensor 35, and a docking assembly 36 fixedly mounted on the torque sensor 35. The docking assembly 36 is provided with two groups, which are respectively docked at both sides of the reducer and drive the docking assembly 36 to dock with the reducer in and out of the docking. The mobile assembly 37 is provided with two groups, which respectively drive the mounting frame 1 31 and the mounting frame 2 32 to move.

[0061] Two torque sensors 35 are provided, and the magnetic powder brake 34 and the motor 33 are both connected to the adjacent torque sensors 35 through a coupling.

[0062] The moving assembly 37 includes: a sliding seat 371 fixedly installed on the mounting frame 1 31 and the mounting frame 2 32, a slide rail 372 slidably connected to the sliding seat 371, and a power source 2 373 fixedly installed on the machine 1; the slide rail 372 is fixedly installed on the machine 1; the mounting frame 1 31 and the mounting frame 2 32 are respectively fixedly connected to the movable ends of the adjacent power source 2 373.

[0063] When the reducer is fixed, the two power sources 373 are started to drive the mounting frame 1 31 and the mounting frame 2 32 to approach each other, thereby driving the two sets of docking components 36 to approach each other, and making the docking components 36 dock with the reducer.

[0064] When the mounting frame 1 31 and the mounting frame 2 32 move, the sliding seat 371 can be driven to slide on the slide rail 372. Through the mutual cooperation between the sliding seat 371 and the slide rail 372, the mounting frame 1 31 and the mounting frame 2 32 can be limited and guided during the movement, thereby improving the stability of the mounting frame 1 31 and the mounting frame 2 32 during movement.

[0065] It is to be added here that the power source 2 373 is preferably a cylinder.

[0066] The docking assembly 36 includes: a connecting cylinder 361 fixedly mounted on the torque sensor 35, a linkage plate 362 for clamping and fixing the rotating shaft of the reducer, and the linkage plate 362 is provided with a plurality of linkage units 363 for driving the linkage plate 362 to move; the linkage unit 363 includes: a sliding plate 3631 slidably mounted in the connecting cylinder 361, an extrusion block 3632 fixedly mounted on the sliding plate 3631, a reset member 3633 for driving the sliding plate 3631 to reset, and a plurality of linkage units 3633 provided on the sliding plate A limiting opening 3634 on 3631, a connecting rod 3635 movably installed in the limiting opening 3634, a connecting block 3636 fixedly installed on the connecting rod 3635, a limiting block 3637 fixedly installed on the connecting rod 3635, and a limiting groove 3638 opened in the connecting tube 361; the connecting plate 362 is fixedly connected to the connecting rod 3635; the limiting block 3637 slides in the limiting groove 3638; the abutting sides of the extrusion block 3632 and the connecting block 3636 are both inclined.

[0067] When the two groups of docking components 36 are close to each other, the two connecting cylinders 361 are respectively sleeved on the output shaft or input shaft of the reducer. When the two sliding plates 3631 are respectively in contact with the output shaft or input shaft of the reducer, the sliding plate 3631 no longer moves, and the connecting cylinder 361 drives the connecting rod 3635 to continue to move, and the connecting rod 3635 drives the connecting block 3636 and the connecting plate 362 to continue to move. Since the contact sides of the extrusion block 3632 and the connecting block 3636 are both inclined, the connecting block 3636 squeezes the extrusion block 3632 when it moves, and the extrusion block 3632 drives the connecting rod 3635 to move, and the connecting rod 3635 drives the connecting plate 362 to move.

[0068] By driving the limiting block 3637 to slide in the limiting groove 3638 through the connecting rod 3635 and limiting the connecting rod 3635 through the limiting opening 3634, a plurality of connecting rods 3635 can be brought close to each other, thereby driving a plurality of connecting plates 362 to be brought close to each other. By bringing a plurality of connecting plates 362 close to each other, the output shaft or input shaft of the reducer can be clamped and fixed in multiple directions, thereby improving the fixing effect of the output shaft or input shaft of the reducer, and further improving the stability of the connection between the test mechanism 3 and the reducer.

[0069] When the test mechanism 3 is connected to the reducer in the present invention, it is only necessary to start the moving component 37 to drive the docking component 36 to approach the reducer, thereby realizing automatic fixation of the docking component 36 to the output shaft or input shaft of the reducer, without the need for manual docking and fixation, thereby improving work efficiency.

[0070] The reset member 3633 includes: a slider 36331 fixedly mounted on the sliding plate 3631, a sliding groove provided in the connecting tube 361, and a reset spring 36332 for driving the sliding plate 3631 to reset; the slider 36331 is slidably mounted in the sliding groove; one end of the reset spring 36332 is fixedly connected to the slider 36331, and the other end of the reset spring 36332 is fixedly connected to the sliding groove.

[0071] During the movement of the connecting cylinder 361, the slider 36331 and the slide groove move relative to each other, thereby causing the reset spring 36332 to be compressed. When the reducer test is completed, the two connecting cylinders 361 are separated from the output shaft or input shaft of the reducer. At this time, the elastic force of the reset spring 36332 can drive the sliding plate 3631 to reset, and then drive the linkage plate 362 to reset, preparing for subsequent use.
