Description
Technical Field
[0001] This utility model relates to the field of automotive parts assembly equipment technology, specifically to an automotive bumper nut riveting device. Background Technology
[0002] Car bumpers are usually made of thin metal sheets. Traditional welded nuts are prone to melting and deformation, and tapping internal threads is easy to strip. Rivet nuts do not require welding or tapping. They can be firmly fixed by stretching the tail with a rivet gun, avoiding damage to the base material.
[0003] When riveting nuts to car bumpers, manual support is required for different types of bumpers, as automatic positioning and clamping of the bumpers is not possible. Furthermore, different car bumpers have different sizes, and a single type of positioning frame cannot meet the stable support requirements of different types of bumpers. In addition, existing riveting machines or pneumatic riveting machines require manual operation, which makes it difficult to ensure the perpendicularity of the nuts. This can easily cause the riveted nuts to be misaligned, making it difficult to tighten the bolts properly during subsequent assembly. Therefore, it is necessary to design a car bumper nut riveting device to solve the above problems. Utility Model Content

Example
[0016] Please refer to Figure 1-4 As shown, this utility model provides a car bumper nut riveting device, including a base 1 and a top frame 6 fixedly installed on the upper end of the base 1. A fixed side frame 2 is fixedly connected to the upper side of the base 1. A movable support plate 3 is provided on the upper end of the fixed side frame 2. A cylinder 4 is fixedly connected to the outer side of the movable support plate 3. The movable rod of the cylinder 4 passes through the movable support plate 3. A positioning clamping plate 5 is fixedly connected to the movable end of the cylinder 4. The cylinder 4 can drive two sets of oppositely arranged positioning clamping plates 5 to move through the extension and retraction control action, thereby enabling lateral limiting clamping of the bumper and ensuring the stability of the bumper nut riveting process. A top frame 6 is fixedly connected to the top of the base 1. A longitudinal adjustment frame 7 is provided on the inner side of the upper end of the top frame 6. A transverse adjustment seat 8 is slidably connected to the inner side of the lower end of the longitudinal adjustment frame 7. A hydraulic cylinder 9 is fixedly connected to the lower end of the transverse adjustment seat 8. A pneumatic riveting machine 10 is fixedly connected to the lower end of the hydraulic cylinder 9. By moving the longitudinal adjustment frame 7 back and forth and the transverse adjustment seat 8 back and forth, the pneumatic riveting machine 10 can be adjusted in horizontal position so that the position of the pneumatic riveting machine 10 can be adapted to the rivet position of the nuts of different bumper models. After the position is adjusted, the pneumatic riveting machine 10 can be controlled to move downward to rivet or move upward to reset by driving the extension and retraction of the hydraulic cylinder 9.
[0017] Specifically, a support platform 11 is fixedly connected to the upper middle position of the base 1, which can provide bottom support for the bumper.
[0018] Specifically, there are four positioning clamps 5. The inner end face of the positioning clamps 5 is fixedly connected with a rubber pad 12. The rubber pad 12 can provide flexible protection between the positioning clamps 5 and the bumper, avoiding hard contact that could cause scratches on the surface of the bumper.
[0019] Specifically, an adjusting screw 13 is rotatably connected inside the fixed side frame 2. The outer end of the adjusting screw 13 passes through the fixed side frame 2, and a turntable 14 is fixedly connected to the outer end of the adjusting screw 13. An adjusting block 15 is spirally connected to the outer side of the inner end of the adjusting screw 13. The adjusting block 15 is slidably connected to the fixed side frame 2 and fixedly connected to the movable support plate 3. By rotating the turntable 14, the adjusting screw 13 can be rotated, thereby allowing the adjusting block 15 to move the movable support plate 3. This allows for adaptive adjustment of the position of the positioning clamp 5 according to the size of different bumper models, thus providing stable support for different bumper models.
[0020] Specifically, a first motor 16 is fixedly connected to the upper side of the rear end face of the top frame 6. A longitudinal screw 17 is fixedly connected to the front end of the output shaft of the first motor 16. The longitudinal screw 17 is rotatably connected to the top frame 6 and helically connected to the longitudinal adjusting frame 7. Limiting guide rods 18 are slidably connected to both the left and right sides of the longitudinal adjusting frame 7. The limiting guide rods 18 are fixedly connected to the top frame 6. By driving the first motor 16 to rotate, the longitudinal screw 17 can rotate, thereby driving the longitudinal adjusting frame 7 to move back and forth along the direction of the limiting guide rods 18.
[0021] Specifically, a second motor 19 is fixedly connected to the upper left side of the top frame 6, and a transverse screw 20 is fixedly connected to the right end of the output shaft of the second motor 19. The transverse screw 20 is rotatably connected to the longitudinal adjustment frame 7, and the transverse screw 20 is helically connected to the transverse adjustment seat 8. The transverse screw 20 can be rotated by driving the second motor 19, and the transverse adjustment seat 8 can move left and right along the inner rail groove of the longitudinal adjustment frame 7 by rotating the transverse screw 20.
[0022] Working Principle: This utility model is a car bumper nut riveting device. When riveting car bumper nuts, the bumper is first placed on the support platform 11. The activation of two opposing cylinders 4 causes two sets of positioning clamps 5 to clamp and limit the bumper from the front-to-back and left-to-right directions. A rubber pad 12 provides flexible protection between the positioning clamps 5 and the bumper, preventing hard contact that could scratch the bumper surface. The rotation of the turntable 14 drives the adjusting screw 13, which in turn moves the adjusting block 15 and the movable support plate 3. This allows for adaptive adjustment of the position of the positioning clamps 5 according to the size of different bumper models, providing stable support for various bumper types. After stable clamping, the first motor 16 and the second motor 19 drive the longitudinal screw 17 and the transverse screw 20 to rotate. The rotation of the longitudinal screw 17 drives the longitudinal adjusting frame 7 to move back and forth along the direction of the limiting guide rod 18. The rotation of the transverse screw 20 drives the transverse adjusting seat 8 to move left and right along the direction of the inner rail groove of the longitudinal adjusting frame 7. This drives the pneumatic riveting machine 10 at the lower end to perform precise horizontal position adjustment. This allows for nut riveting according to the required riveting position of different bumper models. Under the activation and extension of the hydraulic cylinder 9, the pneumatic riveting machine 10 can move up and down to achieve the positioning and riveting of the nut, ensuring the installation angle of the nut and avoiding the angle deviation that would affect the smooth installation of subsequent bolts during manual riveting.
