Description

Technical Field

[0001] This invention relates to the field of dynamic balancing testing technology, specifically a method for dynamic balancing testing of a reducer assembly for new energy vehicles. Background Technology

[0002] Dynamic balance refers to the degree of vibration of the main shaft when it rotates at high speed. During vehicle road testing, the occurrence of booming or ear-piercing noises is related to dynamic imbalance in the transmission system. Therefore, before vehicle assembly, the main reducer assembly in the transmission system needs to be dynamically balanced and corrected to improve product quality and ensure that the main reducer assembly meets the vehicle's performance requirements.

[0003] Existing technology discloses an invention patent concerning a dynamic balancing test method for a new energy vehicle reducer assembly, Chinese patent application number CN201510724761.6, which discloses a dynamic balancing test device for a main reducer assembly. The main reducer assembly includes a main reducer body portion, which includes a main reducer output shaft flange. The dynamic balancing test device for the main reducer assembly includes a base and a drive mechanism and a swing frame support mechanism mounted on the base. The main reducer body portion can be mounted and fixed on the swing frame support mechanism. The drive mechanism is used to drive the main reducer output shaft flange to rotate. The swing frame support mechanism is provided with a detection unit for detecting the amount of swing of the swing frame support mechanism when the main reducer output shaft flange rotates.

[0004] When performing dynamic balancing tests, a belt needs to be placed on the reducer spindle to drive the reducer assembly to rotate. When removing the reducer assembly, one person needs to pry open the belt in order to remove the reducer assembly from the testing device. This method requires multiple people to cooperate, increasing the workload, and is also cumbersome and increases the time required for dynamic balancing tests.

[0005] Based on this, the present invention designs a dynamic balance testing method for a new energy vehicle reducer assembly to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a dynamic balancing test method for a new energy vehicle reducer assembly, in order to solve the problems mentioned in the background art, where a belt needs to be placed on the reducer spindle to drive the reducer assembly to rotate during dynamic balancing testing, and when removing the reducer assembly, one person needs to spread the belt to remove the reducer assembly from the testing device. This method requires multiple people to cooperate, increases the workload, and is cumbersome to operate, increasing the time required for dynamic balancing testing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dynamic balancing test method for a new energy vehicle reducer assembly, the specific steps of which are as follows:

[0008] Step 1: Place the assembled reducer assembly onto the testing device;

[0009] Step 2: Drive the reducer assembly to rotate, and record the test results based on the data obtained from the testing device;

[0010] Step 3: Repeat the test three times, compare and verify the data results;

[0011] Step 4: After confirming that everything is correct, inspect the next reducer assembly;

[0012] The detection device in step one includes a base, a first base fixedly connected to the top of the base, a dynamic balancing tester fixedly connected to the left side of the top of the first base, a first bracket fixedly connected to the top of the dynamic balancing tester, a second bracket fixedly connected to the right side of the top of the first base, and a reducer assembly to be tested placed together by the first bracket and the second bracket. The reducer assembly includes a main shaft, a hydraulic cylinder fixedly connected to the top of the base, and a push plate fixedly connected to the output end of the hydraulic cylinder.

[0013] A movable plate is slidably connected to the right side of the second bracket. A first drive shaft is rotatably connected to the right side of the movable plate. A drive mechanism that drives the first drive shaft to rotate is connected to the right side of the first drive shaft in conjunction with a push plate. A drive wheel is fixedly connected to the surface of the first drive shaft. The drive wheel and the main shaft surface of the reducer assembly are connected together by a conveyor belt. A first slide rod symmetrically distributed in front and back is slidably connected to the movable plate. A first slide groove symmetrically distributed in front and back is opened on the surface of the second bracket. The first slide groove is divided into a straight section and an inclined section. The first slide rod slides along the inner wall of the first slide groove. A first clamping block is fixedly connected to the surface of the first slide rod. A second clamping block symmetrically distributed in front and back is fixedly connected to the movable plate. The second clamping block abuts against the inner side of the conveyor belt. A first return spring is fixedly connected between the first clamping block and the second clamping block. A pressing block is fixedly connected to the top of the first clamping block. A limiting rod symmetrically distributed in front and back is fixedly connected to the right side of the second bracket. The limiting rod abuts against the inclined surface of the pressing block.

[0014] A first connecting rod is rotatably connected to the surface of the first sliding rod, and a second sliding rod is rotatably connected to the other end of the first connecting rod. The second sliding rod slides along the inner wall of the first sliding groove. A second connecting rod is fixedly connected to the surface of the second sliding rod. A third sliding rod is rotatably connected to the outer side of the second connecting rod. A second sliding groove is symmetrically distributed on the right side of the second bracket. The third sliding rod slides along the inner wall of the second sliding groove. A first rotating shaft is rotatably connected to the inner side of the second connecting rod. A roller is fixedly connected to the left side of the surface of the first rotating shaft. The roller abuts against the inner side of the conveyor belt.

[0015] During dynamic balancing testing, a belt needs to be placed on the reducer's main shaft to drive the reducer assembly to rotate. However, removing the reducer assembly requires one person to pry the belt open to remove it from the testing device. This method requires multiple people, increasing workload, and is cumbersome, increasing the time required for dynamic balancing testing. This technical solution solves these problems. The specific working process is as follows: After testing, the hydraulic cylinder is activated, causing the push plate to rise. The drive mechanism no longer rotates the first transmission shaft, and the conveyor belt stops. The push plate pushes the moving plate upwards synchronously. As the moving plate moves the first clamping block and the pressing block upwards, the pressing block disengages from the limit rod. Under the action of the first return spring, the first and second clamping blocks clamp the conveyor belt, thus driving the conveyor belt to move upwards synchronously. As the moving plate continues to rise, the second slide bar moves from the straight section... After entering the inclined section, under the action of the inclined section of the first slide groove, in conjunction with the third slide rod, the second slide rod drives the second connecting rod to move outward. The second connecting rod pulls the conveyor belt to expand forward and backward on both sides through the rollers, so that the conveyor belt moves upward and widens to both sides at the same time, so that the conveyor belt can completely detach from the main shaft of the reducer assembly. By setting the first clamp and the second clamp, in conjunction with the limit rod and the first return spring, when the moving plate rises, the first clamp and the second clamp clamp the conveyor belt and move upward synchronously, so that the conveyor belt can quickly detach from the main shaft of the reducer assembly. By setting the first slide groove, under the action of the second slide rod, the second connecting rod moves upward a certain distance and then moves outward, pulling the conveyor belt to expand to both sides through the rollers, so that the gap between the conveyor belt and the main shaft is larger, so that one person can remove the reducer assembly, saving manpower, shortening the time required for dynamic balancing inspection, and improving inspection efficiency.

[0016] As a further embodiment of the present invention, a gear is fixedly connected to the right side of the surface of the first rotating shaft, and a rack is fixedly connected to the top of the second clamping block. The rack and the gear mesh with each other, and a first extension plate is fixedly connected to the surface of the first rotating shaft. During operation, when the second connecting rod moves outward, it drives the gear and the first rotating shaft to move synchronously. The gear rolls along the surface of the rack, thereby driving the first rotating shaft to rotate. The first rotating shaft drives the first extension plate to flip upward, and the first extension plate pushes the conveyor belt upward, thereby further expanding the gap between the conveyor belt and the main shaft, making it easier to remove the reducer assembly.

[0017] As a further embodiment of the present invention, the first extension plate is provided with a third slide groove, and a second extension plate is slidably connected to the inner wall of the third slide groove. A second return spring is fixedly connected between the second extension plate and the inner wall of the third slide groove. During operation, the first extension plate drives the second extension plate to rotate synchronously. When it encounters the main shaft, the second extension plate retracts inward to avoid the main shaft. As the first extension plate continues to rotate, under the action of the second return spring, the second extension plate pushes the conveyor belt higher, thereby further expanding the gap between the conveyor belt and the main shaft, making it easier for workers to remove the tested reducer assembly.

[0018] As a further embodiment of the present invention, a first support plate is fixedly connected to the inner side of the second extension plate, and a second support plate is fixedly connected to the right side of the second connecting rod. During operation, as the first extension plate drives the second extension plate to rotate, the second support plate can tightly press against the back of the first support plate, thereby allowing the second extension plate to extend to its maximum distance and push the conveyor belt as high as possible. This avoids the problem of limited pushing range of the conveyor belt due to the limited force of the second return spring, and ensures that the gap between the conveyor belt and the main shaft is as large as possible.

[0019] As a further embodiment of the present invention, the driving mechanism includes a second base, which is fixedly connected to a base plate. A sliding plate is slidably connected to the top of the second base. A first spring seat is fixedly connected to the top of the second base. A third return spring is fixedly connected between the first spring seat and the sliding plate. A pressing plate symmetrically distributed front and rear is fixedly connected to the right side of the push plate. The pressing plate is used for the inclined surfaces of the sliding plate to abut against each other. A motor is fixedly connected to the top of the sliding plate. A first mating plate is fixedly connected to the output shaft of the motor. The first mating plate has a mating interface. A second mating plate is fixedly connected to the surface of the first drive shaft. An elastic telescopic rod symmetrically distributed vertically is fixedly connected to the right side of the second mating plate. The rod is locked inside the interface; during operation, the push plate drives the extrusion plate to move upward synchronously. Under the action of the extrusion plate, the slide plate drives the motor to move to the right, thereby causing the elastic telescopic rod to disengage from the interface. The motor no longer drives the first transmission shaft to rotate through the first and second docking plates, thus keeping the conveyor belt stationary during the upward process. By setting the first and second docking plates, when the push plate drives the extrusion plate to move upward synchronously, the extrusion plate causes the slide plate and the motor to move backward, thereby disengaging the first and second docking plates. The motor no longer drives the first transmission shaft to rotate, and the conveyor belt remains stationary. This facilitates the removal of the reducer assembly from the second bracket and avoids personal injury caused by touching the high-speed moving conveyor belt when picking up parts.

[0020] As a further embodiment of the present invention, the movable plate is slidably connected to a support platform symmetrically distributed front and rear. A tensioning wheel is rotatably connected to the top of the support platform. The tensioning wheel abuts against the outer side of the conveyor belt. A second spring seat symmetrically distributed front and rear is fixedly connected to the movable plate. A fourth return spring is fixedly connected between the second spring seat and the support platform. During operation, under the action of the fourth return spring, the tensioning wheel is always in close contact with the surface of the conveyor belt, keeping the conveyor belt taut. This provides an extension margin for subsequent widening of the conveyor belt and avoids the problem of damaging the conveyor belt by forcibly expanding the gap between the conveyor belt and the main shaft.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By setting a first clamping block and a second clamping block, in conjunction with a limiting rod and a first return spring, when the moving plate rises, the first clamping block and the second clamping block clamp the conveyor belt and move upward synchronously, allowing the conveyor belt to quickly disengage from the main shaft of the reducer assembly. By setting a first sliding groove, the second connecting rod moves upward a certain distance under the drive of the second sliding rod and then moves outward. The rollers pull the conveyor belt to expand to both sides, thereby increasing the gap between the conveyor belt and the main shaft. As a result, one person can remove the reducer assembly, saving manpower, shortening the time required for dynamic balancing testing, and improving testing efficiency.

[0023] 2. By setting a second extension plate, under the action of the second return spring, the second extension plate can smoothly pass through the main shaft. In conjunction with the first support plate and the second support plate, the second extension plate can support the conveyor belt higher, thereby maximizing the gap between the conveyor belt and the main shaft, making it easier for workers to remove the tested reducer assembly.

[0024] 3. By setting the first docking plate and the second docking plate, when the push plate drives the extrusion plate to move upward synchronously, the extrusion plate causes the slide plate and the motor to move backward, thereby separating the first docking plate and the second docking plate. The motor no longer drives the first transmission shaft to rotate, and the conveyor belt remains stationary. This facilitates the removal of the reducer assembly from the second bracket and avoids personal injury caused by touching the high-speed moving conveyor belt when picking up parts.

[0044] A movable plate 9 is slidably connected to the right side of the second support 5. A first drive shaft 10 is rotatably connected to the right side of the movable plate 9. A drive mechanism that works with the push plate 8 to drive the first drive shaft 10 to rotate is connected to the right side of the first drive shaft 10. A drive wheel 11 is fixedly connected to the surface of the first drive shaft 10. The drive wheel 11 and the main shaft 601 of the reducer assembly 6 are connected together by a conveyor belt 12. First slide rods 13 are slidably connected to the movable plate 9. First slide grooves 14 are symmetrically distributed on the surface of the second support 5. The first slide grooves 14 are divided into straight sections. Sections 1401 and 1402 are inclined. The first slide rod 13 slides along the inner wall of the first slide groove 14. A first clamping block 15 is fixedly connected to the surface of the first slide rod 13. A second clamping block 16 is fixedly connected to the moving plate 9, which is symmetrically distributed front and back. The second clamping block 16 abuts against the inner side of the conveyor belt 12. A first return spring 17 is fixedly connected between the first clamping block 15 and the second clamping block 16. A pressing block 18 is fixedly connected to the top of the first clamping block 15. A limiting rod 19 is fixedly connected to the right side of the second bracket 5, which is symmetrically distributed front and back. The limiting rod 19 abuts against the inclined surface of the pressing block 18.

[0045] A first connecting rod 20 is rotatably connected to the surface of the first slide rod 13. A second slide rod 21 is rotatably connected to the other end of the first connecting rod 20. The second slide rod 21 slides along the inner wall of the first slide groove 14. A second connecting rod 22 is fixedly connected to the surface of the second slide rod 21. A third slide rod 23 is rotatably connected to the outer side of the second connecting rod 22. A second slide groove 24 is symmetrically distributed on the right side of the second bracket 5. The third slide rod 23 slides along the inner wall of the second slide groove 24. A first rotating shaft 25 is rotatably connected to the inner side of the second connecting rod 22. A roller 26 is fixedly connected to the left side of the surface of the first rotating shaft 25. The roller 26 abuts against the inner side of the conveyor belt 12.

[0046] During operation, when performing dynamic balancing tests, a belt needs to be placed on the reducer spindle to drive the reducer assembly to rotate. However, when removing the reducer assembly, one person is required to spread the belt to remove it from the testing device. This method requires multiple people, increasing workload, and is cumbersome, increasing the time required for dynamic balancing tests. This technical solution solves these problems. The specific working process is as follows: After the test is completed, hydraulic cylinder 7 is activated, driving push plate 8 to rise. The drive mechanism no longer drives the first transmission shaft 10 to rotate, and the conveyor belt 12 remains stationary. Push plate 8 pushes moving plate 9 to move upwards synchronously. As moving plate 9 drives the first clamping block 15 and pressing block 18 upwards, the pressing block 18 disengages from the limiting rod 19. Under the action of the first return spring 17, the first clamping block 15 and the second clamping block 16 clamp the conveyor belt 12, thereby driving the conveyor belt 12 to move upwards synchronously. As moving plate 9 continues to rise, the second slide rod 21 enters the inclined section 1402 from the straight section 1401 and then... Under the action of the inclined section 1402 of 4, in conjunction with the third slide rod 23, the second slide rod 21 drives the second connecting rod 22 to move outward. The second connecting rod 22 pulls the conveyor belt 12 to expand forward and backward on both sides through the roller 26, so that the conveyor belt 12 moves upward and widens to both sides, so that the conveyor belt 12 can completely detach from the main shaft 601 of the reducer assembly 6. By setting the first clamping block 15 and the second clamping block 16, in conjunction with the limiting rod 19 and the first return spring 17, when the moving plate 9 rises, the first clamping block 15 and the first return spring 17 will move outward. The second clamping block 16 clamps the conveyor belt 12 and moves it upwards synchronously, allowing the conveyor belt 12 to quickly disengage from the main shaft 601 of the reducer assembly 6. By setting the first slide groove 14, the second connecting rod 22 moves upwards a certain distance and then outwards under the drive of the second slide rod 21. The roller 26 pulls the conveyor belt 12 to expand to both sides, thereby increasing the gap between the conveyor belt 12 and the main shaft 601. As a result, one person can remove the reducer assembly 6, saving manpower, shortening the time required for dynamic balancing testing, and improving testing efficiency.

[0047] As a further embodiment of the present invention, a gear 27 is fixedly connected to the right side of the surface of the first rotating shaft 25, and a rack 28 is fixedly connected to the top of the second clamping block 16. The rack 28 and the gear 27 mesh with each other. A first extension plate 29 is fixedly connected to the surface of the first rotating shaft 25. During operation, when the second connecting rod 22 moves outward, it drives the gear 27 and the first rotating shaft 25 to move synchronously. The gear 27 rolls along the surface of the rack 28, thereby driving the first rotating shaft 25 to rotate. The first rotating shaft 25 drives the first extension plate 29 to flip upward. The first extension plate 29 pushes the conveyor belt 12 upward, thereby further expanding the gap between the conveyor belt 12 and the main shaft 601, making it easier to remove the reducer assembly 6.

[0048] As a further embodiment of the present invention, the first extension plate 29 is provided with a third slide groove 30, and a second extension plate 31 is slidably connected to the inner wall of the third slide groove 30. A second return spring 32 is fixedly connected between the second extension plate 31 and the inner wall of the third slide groove 30. During operation, the first extension plate 29 drives the second extension plate 31 to rotate synchronously. When it encounters the main shaft 601, the second extension plate 31 retracts inward to avoid the main shaft 601. As the first extension plate 29 continues to rotate, under the action of the second return spring 32, the second extension plate 31 pushes the conveyor belt 12 higher, thereby further expanding the gap between the conveyor belt 12 and the main shaft 601, making it easier for workers to take out the tested reducer assembly 6.

[0049] As a further embodiment of the present invention, a first support plate 33 is fixedly connected to the inner side of the second extension plate 31, and a second support plate 34 is fixedly connected to the right side of the second connecting rod 22. During operation, as the first extension plate 29 drives the second extension plate 31 to rotate, the second support plate 34 can tightly press against the back of the first support plate 33, thereby allowing the second extension plate 31 to extend to its maximum distance and push the conveyor belt 12 as high as possible. This avoids the problem of limited pushing range of the conveyor belt 12 due to the limited force of the second return spring 32, and ensures that the gap between the conveyor belt 12 and the main shaft 601 is as large as possible.

[0050] As a further embodiment of the present invention, the driving mechanism includes a second base 35, which is fixedly connected to the base 1. A slide plate 36 is slidably connected to the top of the second base 35. A first spring seat 37 is fixedly connected to the top of the second base 35. A third return spring 38 is fixedly connected between the first spring seat 37 and the slide plate 36. A pressing plate 39 symmetrically distributed front and rear is fixedly connected to the right side of the push plate 8. The pressing plate 39 is used to abut against the inclined surface of the slide plate 36. A motor 40 is fixedly connected to the top of the slide plate 36. A first docking plate 41 is fixedly connected to the output shaft of the motor 40. A docking interface 42 is provided on the first docking plate 41. A second docking plate 43 is fixedly connected to the surface of the first transmission shaft 10. An elastic telescopic rod 44 symmetrically distributed vertically is fixedly connected to the right side of the second docking plate 43. The elastic telescopic rod 44 is locked inside the docking interface 42. During operation, the push plate 8 pushes the slide plate 36 to the ground. The push plate 8 drives the extrusion plate 39 to move upward synchronously. Under the action of the extrusion plate 39, the slide plate 36 drives the motor 40 to move to the right, thereby causing the elastic telescopic rod 44 to disengage from the docking interface 42. The motor 40 no longer drives the first transmission shaft 10 to rotate through the first docking plate 41 and the second docking plate 43, thus keeping the conveyor belt 12 stationary during the upward process. By setting the first docking plate 41 and the second docking plate 43, when the push plate 8 drives the extrusion plate 39 to move upward synchronously, the extrusion plate 39 causes the slide plate 36 and the motor 40 to move backward, thereby disengaging the first docking plate 41 and the second docking plate 43. The motor 40 no longer drives the first transmission shaft 10 to rotate, and the conveyor belt 12 remains stationary. This facilitates the removal of the reducer assembly 6 from the second support 5 and avoids personal injury caused by touching the high-speed moving conveyor belt 12 when picking up parts.

[0051] As a further embodiment of the present invention, a support platform 45 symmetrically distributed front and rear is slidably connected to the movable plate 9. A tension wheel 46 is rotatably connected to the top of the support platform 45. The tension wheel 46 abuts against the outer side of the conveyor belt 12. A second spring seat 47 symmetrically distributed front and rear is fixedly connected to the movable plate 9. A fourth return spring 48 is fixedly connected between the second spring seat 47 and the support platform 45. During operation, under the action of the fourth return spring 48, the tension wheel 46 is always in close contact with the surface of the conveyor belt 12, keeping the conveyor belt 12 taut. This provides an extension margin for the subsequent widening of the conveyor belt 12, avoiding the problem of damage to the conveyor belt 12 caused by forcibly opening the gap between the conveyor belt 12 and the main shaft 601.
