Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] See Figure 1 ,as well as Figures 3 to 6 This utility model provides a deep groove ball bearing riveting mold, including: a device body 1, a lateral opening groove 2 provided on the device body 1, a fixed seat 3 provided on the bottom wall of the opening groove 2, a concave mold cavity 4 provided on the fixed seat 3, the concave mold cavity 4 being used to place a retainer 5, a hydraulic cylinder 6 provided on the top of the opening groove 2, a movable seat 7 provided on the telescopic end of the hydraulic cylinder 6, and a punch head 8 detachably provided on the movable seat 7;
[0032] The connecting assembly 9 includes a connecting seat 901, a connecting rod 902, and a fixing rod 903. The connecting seat 901 is disposed on the bottom surface of the movable seat 7. The connecting seat 901 is provided with a connecting groove 10. The side wall of the connecting seat 901 is provided with a first through hole 11. The bottom end of the connecting rod 902 is connected to the top surface of the stamping head 8. The top side wall of the connecting rod 902 is provided with a second through hole 12. The fixing rod 903 is provided with a slider 13. The bottom surface of the movable seat 7 is provided with a sliding groove 14. The slider 13 cooperates with the sliding groove 14. The fixing rod 903 slides on the bottom surface of the movable seat 7. A locking member 15 is provided on the side of the slider 13 away from the fixing rod 903. The locking member 15 is used to fix the fixing rod 903 on the movable seat 7.
[0033] When the stamping head 8 is connected to the movable seat 7, the top end of the connecting rod 902 extends into the connecting groove 10, and the end of the fixing rod 903 away from the locking member 15 passes through the first through hole 11 and the second through hole 12.
[0034] The movable seat 7 is located within the opening slot 2 and moves within the opening slot 2 driven by the hydraulic cylinder 6. The movable seat 7 is connected to the stamping head 8 via the connecting assembly 9. The top end of the connecting rod 902 has vertical cut surfaces on both sides. The shape of the connecting groove 10 corresponds to that of the connecting rod 902. That is, when the top end of the connecting rod 902 is inserted into the connecting groove 10, the connecting groove 10 limits the connecting rod 902 in the horizontal direction, preventing the connecting rod 902 from rotating within the connecting groove 10. Furthermore, when the top end of the connecting rod 902 is inserted into the connecting groove 10, the first through hole 11 communicates with the second through hole 12.
[0035] Specifically, first, the device body 1 is placed in the desired position, and the retainer 5 to be processed is placed in the concave mold cavity 4 on the fixed seat 3 in the opening slot 2.
[0036] Then, as needed, select the corresponding specification of the stamping head 8, insert the top end of the connecting rod 902 on the stamping head 8 into the connecting groove 10. The connecting groove 10 limits the connecting rod 902 in the horizontal direction. Move the fixing rod 903, and the slider 13 slides in the sliding groove 14, so that the fixing rod 903 is inserted into the first through hole 11 and the second through hole 12. The fixing rod 903 limits the connecting rod 902 in the vertical direction and controls the locking member 15 to lock it, fixing the connecting rod 902 on the connecting seat 901. Thus, the stamping head 8 and the connecting seat 901 are connected.
[0037] Finally, the hydraulic cylinder 6 is activated, and the telescopic end of the hydraulic cylinder 6 moves downward, driving the moving seat 7 to move. The connecting seat 901 moves synchronously, and the punching head 8 punches the retainer 5 to be processed, applying pressure to the rivets on it to complete the riveting process of the retainer 5.
[0038] It should be noted that in this application, the top of the stamping head 8 of different specifications is provided with a connecting rod 902 of the same specification so as to be compatible with the connecting groove 10.
[0039] See Figure 6 In some embodiments, the bottom end of the connecting rod 902 is connected to the stamping head 8 via a fixing block 16. The fixing block 16 is provided with an abutment groove 17, and the fixing rod 903 is provided with an abutment rod 18.
[0040] The length direction of the abutment rod 18 is perpendicular to the length direction of the fixing rod 903. When the fixing rod 903 passes through the first through hole 11 and the second through hole 12, and the locking member 15 reaches its locked position, the side wall of the abutment rod 18 contacts the inner wall of the abutment groove 17, and the abutment rod 18 abuts against the abutment groove 17. The abutment rod 18 limits the fixing block 16 in the horizontal and vertical directions, thereby making the connection between the connecting rod 902 and the connecting seat 901 more secure.
[0041] In some embodiments, a limiting arc plate 19 is provided on the connecting seat 901, and a slot 20 is provided on the side cut surface of the limiting arc plate 19. When the punch head 8 is connected to the moving seat 7, the slot 20 communicates with the abutment groove 17.
[0042] When the connecting rod 902 is inserted into the connecting groove 10, the fixing block 16 will be inserted between the two side cut surfaces of the limiting arc plate 19. When the connecting rod 902 is inserted into the connecting groove 10, that is, when the first through hole 11 and the second through hole 12 are connected, the slot 20 is connected to the abutment groove 17. When the fixing rod 903 is inserted into the first through hole 11 and the second through hole 12, the abutment rod 18 abuts against the slot 20 and the abutment groove 17 respectively, which further increases the firmness of the connection between the connecting rod 902 and the connecting seat 901.
[0043] See Figure 2 In some embodiments, the locking member 15 includes a rotating rod 1501 and a fastening seat 1502. The rotating rod 1501 is rotatably mounted on the slider 13, and the fastening seat 1502 is mounted on the side wall of the movable seat 7. The fastening seat 1502 is provided with a fastening groove 21.
[0044] The push-pull rotating rod 1501 causes the slider 13 to slide within the slide groove 14, which in turn causes the fixed rod 903 to slide on the movable seat 7. Pushing the rotating rod 1501 causes the fixed rod 903 to pass through the first through hole 11 and the second through hole 12. Then, twisting the rotating rod 1501 causes the rod body of the rotating rod 1501 to engage in the fastening groove 21 of the fastening seat 1502, thereby controlling the position of the slider 13 within the slide groove 14 and thus controlling the relative position of the fixed rod 903 and the movable seat 7.
[0045] In some embodiments, the bottom surface of the movable seat 7 is provided with a guide post 22, and the top surface of the fixed seat 3 is provided with a guide post 23 that matches the guide post 22.
[0046] The guide post 22 has a cavity. When the moving seat 7 moves downward, the guide post 23 enters the cavity of the guide post 22. The clearance fit between the guide post 22 and the guide post 23 increases the radial positioning accuracy of the movement of the punch head 8, prevents the punch head 8 from scraping against the cage 5 to be processed, and also reduces the impact of vibration generated by the moving seat 7 during movement on the accuracy of the punch head 8 when pressing down. There are multiple guide posts 22 and 23, and the number is the same. Preferably, there are three guide posts 22 and 23, which are circumferentially arranged on the moving seat 7 and the fixed seat 3 with the axis of the punch head 8 as the center.
[0047] In some embodiments, a limiting ring 24 is provided on the guide post 23 to limit the downward stroke of the stamping head 8. Further, a gasket 25 is provided on the limiting ring 24. When the moving seat 7 moves downward, the guide post 22 moves downward synchronously, and the guide post 23 enters the cavity of the guide post 22. As the moving seat 7 continues to move downward, the bottom end of the guide post 22 abuts against the gasket 25 on the limiting block 29, preventing the moving seat 7 from moving further downward and avoiding excessive pressure on the holder 5 to be processed, which could damage it. Preferably, the gasket 25 is a rubber gasket 25.
[0048] It should be noted that the position of the limit ring 24 on the guide post 23 can be flexibly adjusted according to the specifications of the cage 5 to be processed and the stamping head 8 of different specifications. This application does not impose any limitation on the specific position of the limit ring 24.
[0049] See Figure 5 In some embodiments, a support base 27 is detachably provided inside the concave mold cavity 4, and a support head 28 is provided on the top surface of the support base 27. The support heads 28 are spaced apart and are used to support the position of the rivet holes of the retainer 5 to be processed. Preferably, a limiting post is provided on the support base 27, and the retainer 5 to be processed is sleeved on the limiting post. This provides precise radial positioning for the retainer 5, reduces the accumulation of errors after multiple movements of the stamping head 8, and shares the lateral force present during the radial movement of the stamping head 8, thus protecting the concave mold cavity 4 to a certain extent.
[0050] In some embodiments, the stamping head 8 is provided with protruding teeth 26, which correspond to the position of the support head 28.
[0051] The protruding teeth 26 on the stamping head 8 correspond to the positions of the support head 28. The support head 28 is located below the retainer 5 to be processed, and the stamping head 8 is located above the retainer 5 to be processed. By driving the stamping head 8 to apply pressure to the rivet holes of the retainer 5 to be processed, the rivets in the rivet holes are riveted, and the upper retainer and the lower retainer are fixed.
[0052] In some embodiments, a limiting block 29 is provided on the outer wall of the support base 27, and a limiting groove 30 matching the limiting block 29 is provided on the fixed base 3. The limiting groove 30 communicates with the concave mold cavity 4. The limiting block 29 and the limiting groove 30 are in clearance fit, which limits the horizontal movement of the support base 27 in the concave mold cavity 4. Due to the gravity of the support base 27, the support base 27 will not fall out of the concave mold cavity 4.
[0053] Work process
[0054] First, place the device body 1 in the desired position, place the support base 27 in the concave mold cavity 4 on the fixed base 3 in the opening slot 2, insert the limiting block 29 into the limiting slot 30, place the retainer 5 to be processed on the support base 27, and align the rivet holes on the retainer 5 to be processed with the support head 28.
[0055] Then, as needed, select the corresponding specification of the stamping head 8, insert the top of the connecting rod 902 on the stamping head 8 into the connecting groove 10, insert the fixing block 16 between the two side cut surfaces of the limiting arc plate 19, limit the connecting rod 902 in the horizontal direction, push the rotating rod 1501, slide the slider 13 in the sliding groove 14, the fixing rod 903 passes through the first through hole 11 and the second through hole 12, the abutting rod 18 abuts against the slot 20 and the abutting groove 17 respectively, limit the connecting rod 902 in the vertical direction, rotate the rotating rod 1501 so that the rod body of the rotating rod 1501 is inserted into the fastening groove 21 of the fastening seat 1502, and fix the connecting rod 902 on the connecting seat 901. Thus, the stamping head 8 and the connecting seat 901 are connected.
[0056] Finally, the hydraulic cylinder 6 is activated, and the telescopic end of the hydraulic cylinder 6 moves downward, driving the moving seat 7 to move. The guide column 22 moves downward synchronously, and the guide column 23 enters the cavity of the guide column 22. The connecting seat 901 moves synchronously, and the punch head 8 punches the retainer 5 to be processed, applying pressure to the rivets on it. The bottom end of the guide column 22 abuts against the gasket 25 on the limiting block 29, completing the riveting process of the retainer 5.
