Detailed implementation manners

[0033] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings.

[0034] As Figure 1As shown in the figure, the first embodiment provided by the present application is an automatic shock absorber assembly device, which includes a frame 1, a turntable 2, an indexer provided on the outer shell 101 for driving the turntable 2 to rotate, and several jigs 3 circumferentially arranged on the turntable 2. It also includes a feeding and pressing mechanism 4 for the outer shell and bushing, a transfer mechanism 5, a cover feeding mechanism 6, a riveting mechanism 7, a torque detection mechanism 8, and a discharging mechanism 9 provided on the frame 1.

[0035] During the actual assembly of the shock absorber, the outer shell 101 and the bushing 102 are provided by the feeding and pressing mechanism 4 for the outer shell and bushing, and the pressing of the outer shell 101 and the bushing 102 is completed. Then, the pressed outer shell 101 and bushing 102 are transferred to the jig 3 through the transfer mechanism 5. The indexer drives the turntable 2 to rotate, so that the jig 3 passes through the cover feeding mechanism 6 in sequence, and the cover feeding mechanism 6 transfers the cover 103 to the pressed outer shell 101 and bushing 102. Then, the cover 103 is screwed and fixed on the upper end face of the outer shell 101 through the riveting mechanism 7. Subsequently, the torque detection mechanism 8 detects whether the cover 103 is screwed qualified, and finally the finished product is discharged through the discharging mechanism 9.

[0036] In the above design, the rapid assembly of the shock absorber of the product can be realized, and the efficiency and accuracy of the shock absorber assembly are improved.

[0037] Specifically: As Figure 1 and Figure 2 shown, the feeding and pressing mechanism 4 for the outer shell and bushing includes an outer shell feeding mechanism 41, a bushing feeding mechanism 42, a bushing detection mechanism 43, a linkage transfer mechanism 44, and a pressing mechanism 45. The outer shell feeding mechanism 41 includes a first mounting frame and a belt conveyor provided on the first mounting frame. The bushing feeding mechanism 42 includes a first vibrating disk, a first linear vibrator 422 docked with the first vibrating disk, and a lifting receiving part 423 provided on the frame 1 for docking with the end of the first linear vibrator 422. The lifting receiving part 423 includes a first column provided on the frame 1, a first air cylinder A arranged along the Z-axis direction on the first column, and a receiving plate provided at the output end of the first air cylinder A.

[0038] During the actual assembly of the outer shell 101 and the bushing 102, the outer shell 101 in the belt conveyor is transferred to the pressing mechanism 45 through the linkage transfer mechanism 44. The bushing 102 is provided by the first vibrating disk. The lifting receiving part 423 receives the bushing 102 flowing out of the first vibrating disk along the first linear vibrator 422. After the lifting receiving part 423 receives the bushing 102, the receiving plate is driven to rise by the first air cylinder A, so that the receiving plate is higher than the first linear vibrator 422. Subsequently, the bushing detection mechanism 43 detects the front and back sides and the circumferential surface of the bushing 102. After the detection is qualified, the bushing 102 is transferred to the pressing mechanism 45 through the linkage transfer mechanism 44 for pressing with the outer shell 101.

[0039] In the above design, the structural design and specific implementation of the shell and bushing feeding and pressing mechanism 4 can quickly realize the detection and pressing of the shell 101 and the bushing 102, improving the pressing efficiency of the shell 101 and the bushing 102.

[0040] Specifically: as Figure 2 shown, the bushing detection mechanism 43 includes a positive and negative detection component 431, an outer periphery detection component 432, and a centering component 433. As Figure 3 shown, the positive and negative detection component 431 includes a first frame A4311 arranged on the frame 1, a first CCD camera 4312 arranged on the first frame A4311, a first support A4313 arranged on the frame 1, a first cylinder B4314 horizontally arranged on the first support A4313, a first rotary cylinder A4315 arranged at the output end of the first cylinder B4314, and a first jaw cylinder A arranged at the output end of the first rotary cylinder A4315. As Figure 6 shown, the outer periphery detection component 432 includes a first support B4321 arranged on the frame 1, a rotating seat B4322 arranged on the first support B4321, a first motor B4323 arranged on the first support B4321 for driving the rotating seat to rotate, and several reflection photoelectrics 4324 arranged on the first support B4321 for detecting the outer periphery of the bushing 102. As Figure 5 shown, the centering component 433 includes a first support D4331 arranged on the frame 1, a guide rail D4332 horizontally arranged on the first support D4331, a pallet D4333 slidably arranged on the guide rail D4332, a first cylinder D4334 arranged on the first support D4331 for driving the pallet D4333 to slide along the guide rail D4332, a first cylinder E4335 arranged on the first support D4331, a positioning plate D4336 arranged at the output end of the first cylinder E4335 and provided with a semi-circular groove, a lifting frame D4337 arranged on the first support D4331, a first electric cylinder D4338 arranged on the first support D4331 for driving the lifting frame D4337 to lift, a pressing head D4339 arranged on the lifting frame, and a first electric cylinder E4330 arranged on the first support D4331 for driving the pressing head.

[0041] When actually detecting the bushing 102, the pillowcase first passes through the front and back detection assembly 431 to detect whether the upper and lower end faces of the bushing 102 are qualified, then passes through the outer periphery detection assembly 432 to detect whether the outer periphery of the bushing 102 is qualified, and finally centers the bushing 102 through the centering assembly 433. The detection method of the front and back detection assembly 431 is as follows: The bushing 102 in the lifting and feeding part 423 is clamped by the first jaw cylinder A, and the first CCD camera 4312 takes a picture of the upper end face of the bushing 102 at this time from above for detection. Then, the first cylinder B 4314 drives the first rotary cylinder A 4315 to retract. After the first rotary cylinder A 4315 drives the first jaw cylinder A to rotate 180°, the first cylinder B 4314 drives the first rotary cylinder A 4315 to reset. At this time, the first CCD camera 4312 detects the other end face of the bushing 102 from above. The detection method of the outer periphery detection assembly 432 is as follows: After the bushing 102 is transferred to the rotary seat B 4322 by the linkage transfer mechanism 44, the rotary seat B 4322 is driven to rotate by the first motor B 4323. During the rotation, the roughness of the outer periphery of the bushing 102 is detected by the reflection photoelectric 4324. The centering method of the centering assembly 433 is as follows: The bushing 102 is placed on the pallet D 4333 through the linkage transfer mechanism 44, and then the pallet D 4333 is driven to move toward the positioning plate D 4336 by the first cylinder D 4334, so that the semi-circular groove of the positioning plate D 4336 abuts against the outer periphery of the bushing 102. Subsequently, the lifting frame D 4337 is driven to move downward by the first electric cylinder D 4338, so that the pressing head D 4339 presses down to detect whether the pressing head D 4339 can extend into the inner wall of the bushing 102.

[0042] In the above design, the structural design and specific implementation method of the bushing detection mechanism 43 can effectively realize the detection of the front and back end face dimensions, outer periphery roughness and hole diameter of the bushing 102.

[0043] Specifically: As Figure 2 and Figure 4 shown, the linkage transfer mechanism 44 includes a first support C 441 arranged on the frame 1, a first guide rail C 442 horizontally arranged on the first support C 441, a first plate C 443 slidably arranged on the first guide rail C 442, a first linear module C 444 arranged at the output end of the first support C 441 for driving the first plate C 443 to slide along the first guide rail C 442, a first clamping part 445, a second clamping part 446 and a third clamping part 447 arranged on the first plate C 443. The first clamping part 445 is used to transfer the bushing 102 from the lifting and feeding part 423 to the outer periphery detection assembly 432, the second clamping part 446 is used to transfer the product from the outer periphery detection assembly 432 to the centering assembly 433, and the third clamping part 447 is used to transfer the product from the centering assembly 433 to the pressing mechanism 45.

[0044] When the linkage transfer mechanism 44 transfers the bushing 102, it simultaneously transfers the bushing 102 from the lifting and feeding part 423 to the outer periphery detection component 432, from the outer periphery detection component 432 to the centering component 433, and from the centering component 433 to the press-fitting mechanism 45. The first linear module C444 drives the first plate C443 to drive the first clamping part 445 to move horizontally, so that the first clamping part 445 transfers the bushing 102 from the lifting and feeding part 423 to the outer periphery detection component 432, the second clamping part 446 transfers the bushing 102 from the outer periphery detection component 432 to the centering component 433, and the third clamping part 447 transfers the bushing 102 from the centering component 433 to the press-fitting mechanism 45.

[0045] In the above design, the structural design and specific implementation method of the linkage transfer mechanism 44 can quickly realize the transfer of the bushing 102, effectively improving the work efficiency.

[0046] Specifically: as Figure 7 shown, the press-fitting mechanism 45 includes a first support F451 arranged on the frame 1, a first rotary cylinder F452 arranged on the first support F451, a rotating plate 453 arranged at the output end of the first rotary cylinder F452, first supporting seats F454 symmetrically arranged at both ends of the rotating plate 453 along the axis of the first rotary cylinder F452, an alignment plate 455 arranged on the first support F451, a lifting frame F456 arranged on the first support F451, a first electric cylinder F457 arranged on the first support F451 for driving the lifting frame F456 to lift and lower, a punch 458 floatingly arranged on the lower end surface of the lifting frame F456, and a first electric cylinder G459 arranged on the first support F451 for driving the punch 458 to press down.

[0047] When actually press-fitting the housing 101 and the bushing 102, the two first supporting seats F454 at both ends of the rotating plate 453 perform operations alternately. When one of the first supporting seats F454 receives the housing 101 and moves to below the alignment plate 455, the linkage transfer mechanism 44 transfers the bushing 102 onto the housing 101. Subsequently, the first electric cylinder F457 drives the lifting frame F456 to move downward. When the punch 458 passes through the through-hole plate and reaches the predetermined position, then the first electric cylinder G459 drives the punch 458 to move downward to press-fit the bushing 102 and the housing 101.

[0048] In the above design, the structural design and specific implementation method of the press-fitting mechanism 45 can effectively realize the rapid press-fitting of the housing 101 and the bushing 102.

[0049] Specifically: as Figure 8As shown in the figure, the cap feeding mechanism 6 includes a second vibrating disk 61 disposed on the frame 1, a second linear vibrator 62 docked with the second vibrating disk 61, a material distributing component 63 docked with the end of the second linear vibrator 62, a second support A 64 disposed on the frame 1, a second linear module A 65 horizontally disposed on the second support A 64, a sliding plate 66 disposed at the output end of the second linear module A 65, a second linear module B 67 disposed on the sliding plate 66 along the Z axis, a connecting frame disposed at the output end of the second linear module B 67, a claw 68 disposed on the connecting frame, and a second CCD camera 69.

[0050] The specific cap feeding process is as follows: The cap 103 is received by the material distributing component 63 from the second vibrating disk 61 flowing out along the second linear vibrator 62. Subsequently, the sliding plate 66 is driven to move by the second linear module A 65, and the connecting frame is driven to move downward by the second linear module B 67, so that the claw 68 picks up the cap 103 in the material distributing component 63. Then, the second linear module A 65 and the second linear module B 67 drive toward the fixture 3 side, and the second CCD camera 69 takes pictures and locates the outer shell 101 and the bushing 102 in the fixture 3. Then, the claw 68 places the cap 103 on the outer shell 101 in the fixture 3.

[0051] In the above design, the structural design and specific implementation manner of the cap feeding mechanism 6 can effectively and quickly place the cap 103 on the outer shell 101 and the bushing 102 that have been press-fitted in the fixture 3.

[0052] Specifically: As Figure 9 and Figure 10As shown in the figure, the riveting mechanism 7 includes a third support 701 arranged on the frame 1, a third guide rail 702 arranged on the third support 701 along the Z-axis direction, a third plate 703 slidably arranged on the third guide rail 702, a third electric cylinder A704 fixedly arranged on the third support 701 for driving the third plate 703 to slide along the third guide rail 702, a riveting main shaft 705 arranged on the third plate 703, a third motor 706 arranged on the third plate 703 for driving the riveting main shaft 705 to rotate, a fixed frame 707 coaxially and fixedly arranged at the lower end of the riveting main shaft 705, a clamping seat 708 arranged in the fixed frame 707, a fastening head 709 floatingly connected with the clamping seat 708 and provided with a transverse through hole, a third spring A710 arranged vertically and with both ends respectively abutted against the upper end of the fastening head 709 and the lower end of the clamping seat 708, a third shaft 711 with both ends passing through the transverse through hole and fixedly connected with both sides of the fixed frame 707, a third spring B713 sleeved on the third shaft 711, two ball bearings 714 arranged on the third shaft 711 and respectively located on both sides of the fastening head 709, and two annular chucks 715. The two annular chucks 715 are respectively fixedly connected with the outer rings of the two ball bearings 714. Both ends of the third spring B713 are respectively abutted against the two ball bearings 714. The annular chuck 715 is provided with an annular step 700 for rolling connection with the outer shell 101.

[0053] It should be noted that a groove for clamping with the fastening head 709 is provided on the upper end surface of the cover 103. An opening is provided at the upper end of the outer shell 101, and the cover 103 is located within the opening.

[0054] The process of riveting the cover 103 and the outer shell 101 is as follows: When the cover 103 is pre-assembled with the outer shell 101 through the cover feeding mechanism 6, the jig 3 rotates with the turntable 2 to the corresponding position of the riveting mechanism 7. The third electric cylinder A704 drives the third plate 703 to move downward, so that the third plate 703 drives the riveting main shaft 705 to move downward until the third spring A710 is compressed and the fastening head 709 is in the groove of the cover 103. Subsequently, the third motor 706 drives the riveting main shaft 705 to rotate, driving the fixed frame 707 and the clamping seat 708 to rotate synchronously. During the rotation of the clamping seat 708, the fastening head 709 is driven to rotate, so that the fastening head 709 drives the cover 103 to rotate and be threadedly fixed with the outer shell 101. During the screwing process, through the rolling of the inner ring and the outer ring of the ball bearing 714, the two annular chucks 715 roll along the outer edge 100 of the opening on the upper end surface of the outer shell 101 through the annular step 700.

[0055] In the above design, the structural design and specific implementation method of the riveting mechanism 7 can realize the rapid fixation of the outer shell 101 and the cover 103.

The indexing device is used to drive the turntable 2 to rotate, so that the fixture 3 sequentially passes through the cover loading mechanism 6, and the cover loading mechanism 6 transfers the cover 103 onto the pressed housing 101 and bushing 102. Then, the cover 103 is screwed and fixed on the upper end surface of the housing 101 through the riveting mechanism 7. Subsequently, the torque detection mechanism 8 is used to detect whether the screwing of the cover 103 is qualified. Finally, the blanking mechanism 9 is used to blank the finished products.

[0064] In the above design, the above method can effectively improve the assembly efficiency of the shock absorber.
