Description

Technical Field

[0001] The present application relates to the field of bearing processing, and in particular to an integrated needle roller bearing processing and testing device and a processing technology thereof. Background Art

[0002] Needle roller bearings are roller bearings with cylindrical rollers. The rollers are thin and long relative to their diameter. Such rollers are called needle rollers. Despite their small cross-section, the bearings still have a high load-bearing capacity. Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact. When the inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest. They are particularly suitable for support structures with limited radial installation dimensions.

[0003] At present, the processing and testing of needle roller bearings are usually divided into two independent links, first processing and then testing. This separate process leads to low production efficiency of the entire needle roller bearing, so it needs to be improved. Summary of the invention

[0004] In order to improve the problem of low production efficiency caused by separate assembly and inspection of needle roller bearings, the present application provides an integrated needle roller bearing processing and inspection device and a processing technology thereof.

[0005] In the first aspect, the present application provides an integrated needle roller bearing processing and testing device that adopts the following technical solution: A needle roller bearing processing and detection integrated equipment comprises a workbench, an assembly mechanism and a detection mechanism, wherein the assembly mechanism and the detection mechanism are both arranged on the workbench, the assembly mechanism is used to assemble the needle roller on the bearing, and the detection mechanism is used to detect the bearing. A track plate is provided on the workbench, the assembly mechanism and the detection mechanism are arranged in sequence along the length direction of the track plate, the bearing is placed on the track plate, and a moving component is provided on the workbench, and the moving component is used to drive the bearing to move on the track plate.

[0006] By adopting the above technical solution, when working, the retainers of several bearings are placed on the track plate in sequence, and the moving assembly is started to drive the retainers of the bearings to move along the length direction of the track plate. When the retainers of the bearings move to the assembly mechanism, the assembly mechanism is started to install several needle rollers on the retainers of the bearings in sequence to complete the processing of the needle roller bearings. Thereafter, the moving assembly is used to drive the bearings to move to the detection mechanism for bearing performance detection. If the detection is qualified, the production of one bearing can be completed. In this process, the processing, assembly and quality detection of the bearings are all carried out at one station. Driven by the moving assembly, the processing and detection of the bearings are carried out continuously, which improves the efficiency of bearing processing and production.

[0007] Optionally, a positioning cylinder is provided on the workbench, and the positioning cylinder is located on the side of the assembly mechanism away from the detection mechanism. The output end of the positioning cylinder is connected to a positioning rod, and the positioning rod is located directly above the track plate. The positioning cylinder is used to drive the positioning rod to move up and down, and the positioning rod can be adapted to be inserted into the bearing.

[0008] By adopting the above technical solution, when the bearing retainer reaches the bottom of the positioning cylinder, the positioning cylinder is started to drive the positioning rod downward so that the positioning rod is inserted into the bearing. The positioning rod will use its side surface to push the inner ring side wall of the retainer so that the retainer can be coaxial with the positioning rod, thereby realizing the positioning of the retainer on the track plate and ensuring that the moving assembly can accurately clamp the bearing and drive the bearing to move.

[0009] Optionally, the moving component includes a moving cylinder, a moving plate, a pushing cylinder and a limit plate. The moving cylinder is arranged on the workbench, the moving plate is connected to the output end of the moving cylinder, the moving cylinder is used to drive the moving plate to move along the length direction of the track plate, the pushing cylinder is arranged on the moving plate, the output end of the pushing cylinder is connected to the limit plate, the pushing cylinder is used to drive the limit plate to move toward or away from the track plate, and a limiting hole for inserting a bearing is provided on the side of the limit plate close to the track plate.

[0010] By adopting the above technical scheme, in the initial state, the limit plate is located on one side of the track plate and faces the assembly mechanism. When the bearing needs to be moved, the push cylinder is first started to move the limit plate toward the track plate, so that the bearing on the track plate is relatively inserted in the corresponding limit hole. Then the moving cylinder is started to drive the moving plate to move toward the detection mechanism, so that the limit plate moves along the track plate, and then drives the bearing to move on the track plate toward the detection mechanism, realizing the translation of the bearing, completing the assembly and detection of the bearing in sequence, so that the entire bearing production process is carried out continuously, thereby improving the efficiency of bearing production.

[0011] Optionally, a cleaning component is provided on the workbench, and the cleaning component includes a camera, a cleaning cylinder and a cleaning plate. The camera is arranged on the workbench through a bracket, and the output end of the camera is aimed at the track plate for photographing the bearings on the track plate. The cleaning cylinder is arranged on the workbench, and the output end of the cleaning cylinder is fixed to the cleaning plate for driving the cleaning plate to move toward or away from the track plate. A cleaning hole is opened on the track plate, and the cleaning plate can be fitted and inserted in the cleaning hole, and the cleaning plate is flush with the track plate.

[0012] By adopting the above technical solution, after the needle roller is assembled on the bearing retainer, the limit plate drives the bearing to the bottom of the camera, and through the camera shooting, it is determined whether there is any needle leakage on the bearing, and then it is driven to the cleaning plate by the limit plate. If there is no needle leakage, under the push of the subsequent limit plate, the bearing can be moved from the cleaning plate to the track plate again, and reach the detection mechanism for rotation flexibility detection. If there is a needle leakage, it is a defective product. At this time, the cleaning cylinder is started to drive the cleaning plate to move away from the track plate, and the bearing on the cleaning plate is restricted by the raised part of the track plate and cannot move synchronously with the cleaning plate. When the cleaning plate is completely pulled out of the cleaning hole, the cleaning hole is in an open state, so that the defective bearing originally on the cleaning plate loses support and falls into the cleaning hole, thereby achieving the removal of defective products.

[0013] Optionally, a flipping assembly is provided between the positioning cylinder and the assembly mechanism, and a flipping assembly is also provided between the cleaning assembly and the detection mechanism. The flipping assembly includes a rotating motor and two clamping plates. The rotating motor is provided on the workbench. A rotating block is fixed to the output end of the rotating motor. The two clamping plates are relatively arranged on the rotating block. The two clamping plates can approach or move away from each other on the rotating block. One of the clamping plates is flush with the track plate and is used to receive the bearing.

[0014] By adopting the above technical solution, when it is necessary to assemble the needle roller on the bearing, the bearing retainer will first reach the flipping assembly, that is, it will be located on one of the clamping plates to observe whether the bearing is the assembly surface. If so, wait for the limit plate to push the bearing to the assembly mechanism. If not, drive the two clamping plates closer to each other to clamp the bearing, then start the rotating motor to drive the rotating block to flip the clamping plate, so that the clamping plate clamps the bearing and flips 180° to realize the flipping of the bearing, and then open the two clamping plates and wait for the limit plate to push the bearing to the assembly mechanism.

[0015] Optionally, the rotating block is provided with a driving component for driving the clamping plate to move, the driving component includes a driving cylinder, a driving block and two magnetic blocks that attract each other, the driving cylinder is arranged in the rotating block, the output end of the driving cylinder is fixed to the driving block, the driving cylinder is used to drive the driving block to move toward or away from the clamping plate, the two magnetic blocks are respectively fixed to the two clamping plates, a guide surface is provided on the side of the magnetic block close to the driving block, the driving block abuts against the guide surface, and is used to drive the two magnetic blocks to move away from each other.

[0016] By adopting the above technical solution, in the initial state, the two magnetic blocks are attracted to each other, so that the two clamping plates are in a state of abutment, and the driving cylinder is started to drive the driving block to abut against the guide surface. The guide surface plays a guiding role, so that the driving block slides relatively on the guide surface, so that the two magnetic blocks move away from each other, that is, the two clamping plates are opened to facilitate the insertion of the bearing. When the bearing needs to be flipped, the driving cylinder is used to drive the driving block to reset, the magnetic block loses the abutment of the driving block, and the two magnetic blocks approach each other under the attraction of magnetic force, so that the two clamping plates can clamp and fix the bearing.

[0017] Optionally, a transfer mechanism is provided on the workbench, and the transfer mechanism is located on the side of the detection mechanism away from the assembly mechanism. A plurality of support rods are fixed on the workbench, and the support rods are vertically arranged. The transfer mechanism is used to set the bearing sleeve on the track plate on the support rods.

[0018] By adopting the above technical solution, after the bearing has been inspected by the detection mechanism, it is moved to the transfer mechanism under the drive of the limit plate. At this time, the transfer mechanism is started to clamp the bearing on the track plate, and then the bearing is transported to the support rod so that the support rod is relatively inserted into the bearing. At this time, the transfer mechanism relaxes the clamping force on the bearing, so that the bearing is sleeved on the support rod and moves along the support rod to complete the storage of the bearing.

[0019] Optionally, the transfer mechanism includes a connecting frame, a lifting cylinder, a transfer cylinder and a clamping assembly. The connecting frame is fixed to the workbench, the lifting cylinder is arranged on the connecting frame through the transfer cylinder, the transfer cylinder is used to drive the lifting cylinder to move to the support rod, the output end of the lifting cylinder is connected to the clamping assembly, the lifting cylinder is used to drive the clamping assembly to move toward or away from the track plate, the clamping assembly is used to clamp the bearing, and the support rod can abut against the clamping assembly to disassemble the bearing on the clamping assembly.

[0020] By adopting the above technical solution, when the bearing reaches the transfer assembly, the transfer cylinder is first used to drive the lifting cylinder to align with the track plate, and then the lifting cylinder is started to drive the clamping assembly downward until the clamping assembly abuts against the bearing on the track plate and clamps the bearing. Subsequently, the lifting cylinder drives the clamping assembly to move the bearing upward, and then the transfer cylinder is started to make the bearing reach directly above the support rod. At this time, the clamping assembly loosens the bearing so that the bearing is aligned with the support rod and is sleeved on the support rod.

[0021] Optionally, the clamping assembly includes a mounting sleeve and two clamping plates, the mounting sleeve being arranged on the output end of the lifting cylinder, the middle part of the clamping plate being hinged on the inner wall of the mounting sleeve, the two clamping plates being symmetrically arranged with the central axis of the mounting sleeve as the axis, the clamping plate being connected to the inner wall of the mounting sleeve through a connecting spring, the connecting spring being used to drive the two clamping plates to approach each other, a positioning block is fixed on the side wall of the clamping plate close to the central axis of the mounting sleeve, a sliding surface is provided on the opposite side walls of the two positioning blocks, the top end of the support rod can abut against the sliding surface to drive the two positioning blocks away from each other, and a barb is provided on the side wall of the mounting sleeve where the bottom end of the clamping plate extends, and the barb can be hooked on the bearing.

[0022] By adopting the above technical scheme, when the lifting cylinder drives the mounting sleeve to reach the bearing, the mounting sleeve is coaxial with the bearing, and the barb is inserted into the bearing, so that the side wall of the barb abuts against the inner wall of the bearing and relatively squeezes the barb, so that the clamping plate deflects toward the direction of the center axis of the mounting sleeve, that is, the connecting spring is compressed and deformed, so that the barb can be fully inserted into the bearing, and when the barb reaches the bottom of the bearing, the barb is separated from the inner wall of the bearing, and the connecting spring recovers the deformation at this time, driving the barb to deflect in the direction away from the mounting sleeve, that is, the two barbs open, thereby supporting the inner wall of the bearing, and achieving fixed clamping of the bearing.

[0023] When the bearing reaches the support rod, the mounting sleeve is inserted into the support rod with the bearing, and the support rod abuts against the sliding surface. The sliding surface plays a guiding role, so that the support rod slides relatively on the sliding surface, thereby making the two positioning blocks move away from each other, that is, the clamping plate squeezes the connecting spring and moves away from the center axis of the mounting sleeve, so that the clamping plate drives the barb to tilt synchronously, that is, the barb relaxes the force of the support on the bearing, so that the bearing falls under the action of gravity and is finally mounted on the support rod.

[0024] In the second aspect, the processing technology of a needle roller bearing processing and testing integrated equipment provided by the present application adopts the following technical solution: S1. Place the bearing cage on the track plate, and use the moving assembly to send the bearing to the assembly mechanism for needle roller assembly; S2. After assembly, use the cleaning assembly to check whether there is any needle leakage on the bearing; S3, the mobile assembly sends the qualified bearings to the testing mechanism for flexibility testing, and the qualified products are then transported to the transfer mechanism; S4. The transfer mechanism clamps the bearings from the track plate and moves them to the support rod, and sets them on the support plate one by one for storage.

[0025] In summary, the present application includes at least one of the following beneficial effects: 1. During operation, place the cages of several bearings on the track plate in sequence, start the moving assembly, and drive the cages of the bearings to move along the length direction of the track plate. When the cages of the bearings move to the assembly mechanism, start the assembly mechanism to install several needle rollers on the cages of the bearings in sequence to complete the processing of the needle roller bearings. After that, use the moving assembly to drive the bearings to move to the testing mechanism to test the bearing performance. If the test is qualified, the production of one bearing is completed. In this process, the processing, assembly and quality testing of the bearings are all carried out at one station. Driven by the moving assembly, the processing and testing of the bearings are carried out continuously, which improves the efficiency of bearing processing and production; 2. When the lifting cylinder drives the mounting sleeve to reach the bearing, the mounting sleeve is coaxial with the bearing, and the barb is inserted into the bearing, so that the side wall of the barb abuts against the inner wall of the bearing and relatively squeezes the barb, so that the clamping plate deflects in the direction of the central axis of the mounting sleeve, so that the barb can be fully inserted into the bearing, and then the connecting spring restores the deformation, driving the barb to deflect in the direction away from the mounting sleeve, that is, the two barbs open, thereby supporting the inner wall of the bearing and achieving fixed clamping of the bearing; when the bearing reaches the support rod, the mounting sleeve is inserted into the support rod with the bearing, and the support rod abuts against the sliding surface, pushing the two positioning blocks away from each other, so that the clamping plate drives the barb to tilt synchronously, that is, the barb relaxes the force of the support on the bearing, so that the bearing falls under the action of gravity, and is finally sleeved on the support rod to complete the storage.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-7 This application is described in further detail.

[0029] The present application embodiment discloses an integrated needle roller bearing processing and detection device. Figure 1 and Figure 2 The integrated equipment for processing and detecting needle roller bearings includes a workbench 10, an assembly mechanism 90 and a detection mechanism 110. The assembly mechanism 90 and the detection mechanism 110 are both arranged on the workbench 10. A track plate 20 is fixed on the workbench 10. The assembly mechanism 90 and the detection mechanism 110 are arranged in sequence along the length direction of the track plate 20. The bearing is placed on the track plate 20. A moving component 30 is provided on the workbench 10. The moving component 30 is used to drive the bearing to move on the track plate 20 from the assembly mechanism 90 to the detection mechanism 110.

[0030] Reference Figure 1 and Figure 2 , wherein the assembly mechanism 90 includes a mounting frame and two assembly components, the mounting frame is fixed on the workbench 10, the assembly components include a rotating motor 61 and an assembly cylinder, the rotating motor 61 is mounted on the mounting frame, the output shaft of the rotating motor 61 is connected with a rotating rod, the rotating rod can be inserted into the bearing and drive the bearing to rotate, the assembly cylinder is also mounted on the mounting frame, the output end of the assembly cylinder is connected to the needle roller, and can drive the needle roller to move up and down, each time the assembly cylinder is pressed down on the bearing, the needle roller can be assembled on the bearing, the rotating motor 61 is used to drive the bearing to rotate, so that the assembly cylinder can install the needle roller along the circumference direction of the bearing to complete the processing of the needle roller bearing.

[0031] Reference Figure 1 and Figure 2The detection mechanism 110 includes a rotating motor and a rotating block installed on the output shaft of the rotating motor. A pressing cylinder is installed on the workbench. The pressing cylinder is connected to the rotating motor to drive the rotating block on the rotating motor to press against the bearing. The rotating motor is started to drive the rotating block to drive the bearing to rotate at high speed. Then the rotating motor stops. By observing how long the rotating block adjacent to the bearing can rotate, the flexibility of the needle roller after the bearing processing is completed can be measured to reflect its yield rate.

[0032] Reference Figure 1 and Figure 2 The moving assembly 30 includes a moving cylinder 31, a moving plate 32, a pushing cylinder 33 and a limiting plate 34. The moving cylinder 31 is arranged on the workbench 10, and the moving plate 32 is connected to the output end of the moving cylinder 31. The moving cylinder 31 is used to drive the moving plate 32 to move along the length direction of the track plate 20. The pushing cylinder 33 is arranged on the moving plate 32, and the output end of the pushing cylinder 33 is connected to the limiting plate 34. The pushing cylinder 33 is used to drive the limiting plate 34 to move toward or away from the track plate 20. A plurality of limiting holes 341 are provided on the side of the limiting plate 34 close to the track plate 20.

[0033] In the initial state, the limit plate 34 is located on one side of the track plate 20 and faces the assembly mechanism 90. When the bearing assembly is completed and needs to be moved, the push cylinder 33 is first started to move the limit plate 34 toward the track plate 20, so that the bearing on the track plate 20 is relatively inserted in the corresponding limit hole 341, and then the moving cylinder 31 is started to drive the moving plate 32 to move toward the detection mechanism 110, so that the limit plate 34 moves along the track plate 20, and then drives the bearing to move on the track plate 20 toward the detection mechanism 110 to achieve translation of the bearing. In this process, the processing, assembly and quality inspection of the bearing are all carried out at one workstation. Driven by the moving component 30, the assembly and inspection of the bearing are completed in sequence, so that the entire bearing production process is carried out continuously, thereby improving the efficiency of bearing production.

[0034] Reference Figure 1 and Figure 2 , wherein the limit plate 34 drives the bearing to move, and acts on the bearing at a fixed position on the track plate 20, so it is necessary to ensure the stability of the initial position of the bearing. A positioning cylinder 40 is installed on the workbench, and the positioning cylinder 40 is located on the side of the assembly mechanism 90 away from the detection mechanism 110. The output end of the positioning cylinder 40 is connected to a positioning rod 41, and the bottom end of the positioning rod 41 is a cone structure. The positioning rod 41 is located directly above the track plate 20. The positioning cylinder 40 is used to drive the positioning rod 41 to move up and down, and the positioning rod 41 can be adapted to be inserted into the bearing.

[0035] When the bearing retainer reaches the bottom of the positioning cylinder 40, the positioning cylinder 40 is started to drive the positioning rod 41 downward so that the positioning rod 41 is inserted into the bearing. The vertebral structure at the end of the positioning rod 41 will use its side surface to push the inner ring side wall of the retainer, so that the retainer can be coaxial with the positioning rod 41, thereby realizing the positioning of the retainer on the track plate 20 and ensuring that the moving assembly 30 can accurately clamp the bearing and drive the bearing to move.

[0036] Reference Figure 1 and Figure 3 After the needle roller assembly on the bearing is completed, in order to screen out the incompletely assembled bearings, a cleaning component 50 is provided on the workbench 10. The cleaning component 50 is used to clean the bearings that are not assembled in place on the track plate 20. The cleaning component 50 includes a camera 51, a cleaning cylinder 52 and a cleaning plate 53. The camera 51 is arranged on the workbench 10 through a bracket. The output end of the camera 51 is aimed at the track plate 20 for photographing the bearings on the track plate 20. The cleaning cylinder 52 is arranged on the workbench 10. The output end of the cleaning cylinder 52 is fixed to the cleaning plate 53 for driving the cleaning plate 53 to move toward or away from the track plate 20. A cleaning hole 21 is provided on the track plate 20. The cleaning plate 53 can be adapted to be inserted in the cleaning hole 21, and the cleaning plate 53 is flush with the track plate 20. A through hole is also provided at a position corresponding to the cleaning hole 21 on the workbench 10. A receiving plate is installed in the through hole to receive the defective bearings that fall from the cleaning hole 21.

[0037] After the needle rollers are assembled on the retaining frame of the bearing, the limit plate 34 drives the bearing to the bottom of the camera 51. By shooting with the camera 51, it is determined whether there is any needle leakage on the bearing. Then, the limit plate 34 drives the bearing to the cleaning plate 53. If there is no needle leakage, the bearing can be moved from the cleaning plate 53 to the track plate 20 again under the push of the subsequent limit plate 34, and reach the detection mechanism 110 for rotation flexibility detection. If there is a needle leakage, it is a defective product. At this time, the cleaning cylinder 52 is started to drive the cleaning plate 53 to move away from the track plate 20. The bearing on the cleaning plate 53 is restricted by the raised part on the track plate 20 and cannot move synchronously with the cleaning plate 53. When the cleaning plate 53 is completely pulled out of the cleaning hole 21, the cleaning hole 21 is in an open state, so that the defective bearing originally on the cleaning plate 53 loses support and falls into the cleaning hole 21, thereby achieving the removal of defective products.

[0038] Reference Figure 1 and Figure 4, where the assembly surface and the detection surface of the bearing are different, and the bearing needs to be turned over according to the situation, a flip component 60 is provided between the positioning cylinder 40 and the assembly mechanism 90, and a flip component 60 is also provided between the cleaning component 50 and the detection mechanism 110. The flip component 60 includes a rotating motor 61 and two clamping plates 63. The rotating motor 61 is arranged on the workbench 10, and a rotating block 62 is fixed to the output end of the rotating motor 61. The two clamping plates 63 are relatively arranged on the rotating block 62. A driving component 70 is provided on the rotating block 62. The driving component 70 is connected to the clamping plate 63 and can drive the two clamping plates 63 to move closer to or away from each other on the rotating block 62. One of the clamping plates 63 is flush with the track plate 20 and is used to receive the bearing.

[0039] When the needle roller on the bearing needs to be assembled, the bearing retainer will first arrive at the flip assembly 60, that is, located on one of the clamping plates 63, to observe whether the bearing is the assembly surface. If so, wait for the limit plate 34 to push the bearing to the assembly mechanism 90. If not, use the drive assembly 70 to drive the two clamping plates 63 to approach each other to clamp the bearing, then start the rotating motor 61, drive the rotating block 62 to drive the clamping plate 63 to flip, so that the clamping plate 63 clamps the bearing and flips 180° to realize the bearing flipping, then open the two clamping plates 63, and wait for the limit plate 34 to push the bearing to the assembly mechanism 90. Similarly, observe whether the bearing is the detection surface, and use the clamping plate 63 to clamp and flip according to actual needs.

[0040] Reference Figure 4 and Figure 5 The driving assembly 70 includes a driving cylinder 71, a driving block 72 and two magnetic blocks 73. The driving cylinder 71 is arranged in the rotating block 62. The output end of the driving cylinder 71 is fixed to the driving block 72. The driving cylinder 71 is used to drive the driving block 72 to move toward or away from the clamping plate 63. The two magnetic blocks 73 are respectively fixed to the two clamping plates 63. A guide surface 731 is provided on the side of the magnetic block 73 close to the driving block 72. The driving block 72 abuts against the guide surface 731 to drive the two magnetic blocks 73 to move away from each other.

[0041] In the initial state, the two magnetic blocks 73 are attracted to each other, so that the two clamping plates 63 are in abutment with each other, and the driving cylinder 71 is started to drive the driving block 72 to abut against the guide surface 731. The guide surface 731 plays a guiding role, so that the driving block 72 slides relatively on the guide surface 731, so that the two magnetic blocks 73 move away from each other, that is, the two clamping plates 63 open to facilitate the insertion of the bearing. When the bearing needs to be turned over, the driving cylinder 71 is used to drive the driving block 72 to reset, and the magnetic block 73 loses the abutment of the driving block 72. The two magnetic blocks 73 are attracted by the magnetic force and move closer to each other, so that the two clamping plates 63 can clamp and fix the bearing.

[0042] Reference Figure 1 and Figure 6 After the bearings are produced, they need to be stored. A transfer mechanism 80 is provided on the workbench 10. The transfer mechanism 80 is located on the side of the detection mechanism 110 away from the assembly mechanism 90. A plurality of support rods 11 are fixed on the workbench 10. The support rods 11 are vertically arranged. The transfer mechanism 80 is used to set the bearing sleeve on the track plate 20 on the support rods 11.

[0043] Reference Figure 1 and Figure 6 The transfer mechanism 80 includes a connecting frame 81, a lifting cylinder 82, a transfer cylinder 83 and a clamping assembly 84. The connecting frame 81 is fixed on the workbench 10. The transfer cylinder 83 is installed on the top of the connecting frame 81 and is connected to the shell of the lifting cylinder 82. It can drive the lifting cylinder 82 to move horizontally, and the lifting cylinder 82 is vertically arranged. Driven by the transfer cylinder 83, it can be aligned with the track plate 20 or the support rod 11.

[0044] Reference Figure 6 and Figure 7 The output end of the lifting cylinder 82 is connected to the clamping assembly 84, and the clamping assembly 84 includes a mounting sleeve 841 and two clamping plates 842. The mounting sleeve 841 is fixed on the output end of the lifting cylinder 82, and the mounting sleeve 841 is vertically arranged. The clamping plate 842 is rotatably connected to the inner wall of the mounting sleeve 841 through a rotating shaft. The two clamping plates 842 are arranged symmetrically with the central axis of the mounting sleeve 841 as the axis. The clamping plate 842 is connected to the inner wall of the mounting sleeve 841 through a connecting spring 844. The connecting spring 844 is used to drive the two clamping plates 842 to approach each other. A positioning block 843 is fixed on the side wall of the plate 842 close to the central axis of the mounting sleeve 841, and the two positioning blocks 843 are abutted against each other. Sliding surfaces 8431 are cut on the opposite side walls of the two positioning blocks 843. The bottom end of the sliding surface 8431 is inclined in the direction away from the central axis of the mounting sleeve 841. The top end of the support rod 11 can abut against the sliding surface 8431 to drive the two positioning blocks 843 away from each other. The bottom end of the clamping plate 842 extends out of the mounting sleeve 841 and a barb 8421 is integrally formed on the side wall of the clamping plate 842 away from the central axis of the mounting sleeve 841.

[0045] When the lifting cylinder 82 drives the mounting sleeve 841 to reach the bearing, the mounting sleeve 841 is coaxial with the bearing, and the barb 8421 is inserted into the bearing, so that the side wall of the barb 8421 abuts against the inner wall of the bearing and relatively squeezes the barb 8421, so that the clamping plate 842 deflects toward the direction of the center axis of the mounting sleeve 841, that is, the connecting spring 844 is compressed and deformed, so that the barb 8421 can be fully inserted into the bearing, and when the barb 8421 reaches the bottom of the bearing, that is, the barb 8421 is separated from the inner wall of the bearing, at this time the connecting spring 844 recovers its deformation and drives the barb 8421 to deflect in the direction away from the mounting sleeve 841, that is, the two barbs 8421 open, thereby supporting the inner wall of the bearing and achieving fixed clamping of the bearing.

[0046] When the bearing reaches the support rod 11, the mounting sleeve 841 is inserted into the support rod 11 with the bearing, and the support rod 11 abuts against the sliding surface 8431. The sliding surface 8431 plays a guiding role, so that the support rod 11 slides relatively on the sliding surface 8431, thereby making the two positioning blocks 843 move away from each other, that is, the clamping plate 842 squeezes the connecting spring 844 and moves in the direction away from the central axis of the mounting sleeve 841, so that the clamping plate 842 drives the barb 8421 to tilt synchronously, that is, the barb 8421 relaxes the force of expanding the bearing, so that the bearing falls under the action of gravity and is finally mounted on the support rod 11.

[0047] The implementation principle of the integrated equipment for processing and testing needle roller bearings in the embodiment of the present application is as follows: when working, the retaining frames of several bearings are placed on the track plate 20 in sequence, and the moving assembly 30 is started to drive the retaining frames of the bearings to move along the length direction of the track plate 20. When the retaining frames of the bearings move to the assembly mechanism 90, the assembly mechanism 90 is started to install several needle rollers on the retaining frames of the bearings in sequence to complete the processing of the needle roller bearings. Thereafter, the moving assembly 30 is used to drive the bearings to move to the testing mechanism 110 to test the bearing performance. If the test is qualified, the production of one bearing can be completed. In this process, the processing, assembly and quality testing of the bearings are all carried out at one station. Driven by the moving assembly 30, the processing and testing of the bearings are carried out continuously, which improves the efficiency of the bearing processing and production.

[0048] The present application also discloses a processing technology of a needle roller bearing processing and detection integrated device, comprising the following steps: S1. Place the bearing cage on the track plate 20, and use the moving assembly 30 to send the bearing to the assembly mechanism 90 for needle roller assembly; S2, after the assembly is completed, use the cleaning assembly 50 to detect whether there is a needle missing on the bearing; S3, the moving assembly 30 sends the qualified bearings to the testing mechanism 110 for flexibility testing, and the qualified products are then sent to the transfer mechanism 80; S4, the transfer mechanism 80 clamps the bearings from the track plate 20, moves them to the support rod 11, and sets them one by one on the support plate for storage.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
