Description

Technical Field

[0001] This utility model relates to the field of riveting machine technology, and specifically to a hexagonal riveting nut angle adjustment device. Background Technology

[0002] In new energy vehicles and related fields, hexagonal rivet nuts are required. During production, hexagonal rivet nuts are fed automatically and then riveted by a rivet gun. In this process, because the angle of the hexagonal rivet nuts cannot be guaranteed, the rivet gun cannot accurately position itself during riveting, thus affecting the efficiency of automated production.

[0003] Therefore, based on the aforementioned shortcomings of the existing hexagonal rivet nut feeding device, it is necessary to improve the existing hexagonal rivet nut feeding device. Utility Model Content

[0004] The purpose of this utility model is to provide a hexagonal rivet nut angle adjustment device to address the shortcomings of existing technologies. This hexagonal rivet nut angle adjustment device solves the defects of existing hexagonal rivet nut feeding devices, such as the inability to accurately position the nuts.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] A hexagonal rivet nut angle adjustment device includes a bracket and a sleeve. The sleeve has an inner hole for carrying the hexagonal rivet nut. The bracket is equipped with a feed pipe for feeding the hexagonal rivet nut. The sleeve is movably located below the feed pipe and can move horizontally, move vertically, and rotate.

[0007] Furthermore, the support is equipped with a translation seat on its side, which is equipped with a translation cylinder. A lifting cylinder and a longitudinal slide rail are mounted on the translation seat, and a lifting seat slides along the longitudinal slide rail. The lifting cylinder drives the lifting seat to rise and fall, and the sleeve is mounted on the lifting seat. The horizontal movement of the sleeve is achieved by moving the translation seat, and the vertical movement of the sleeve is achieved by raising and lowering the lifting seat.

[0008] Furthermore, the lifting seat includes a horizontal lifting plate, which is connected to the telescopic rod of the lifting cylinder, and a sleeve seat is installed on the lifting plate. The lifting plate is raised and lowered by the lifting cylinder.

[0009] Furthermore, a sleeve seat is installed on the lifting base, and a rotary cylinder is installed on the side of the sleeve seat. A meshing rack and gear are installed inside the sleeve seat, and the sleeve is fixed in the middle of the gear. The rotary cylinder drives the rack. Driven by the rotary cylinder, the gear rotates, thereby causing the sleeve to rotate, thus perfectly matching the angle of the hexagonal rivet nut. Regardless of the angle of the fed hexagonal rivet nut, it can perfectly match the inner hole of the sleeve.

[0010] Furthermore, the bracket is equipped with a finger cylinder, which has a clamping arm. The clamping arm is used to clamp the head of the hexagonal rivet nut for positioning.

[0011] Furthermore, the bracket is equipped with a horizontally movable pressure plate, and a pressure plate cylinder is fixed to the bracket, which drives the pressure plate. When the sleeve moves the hexagonal rivet nut upward, the pressure plate blocks the hexagonal rivet nut.

[0012] Furthermore, the clamping part of the clamping arm is located below the feed tube to clamp the hexagonal rivet nut.

[0013] Furthermore, the bracket is equipped with a limiting sleeve, and the clamping arm is located above the limiting sleeve, so that when the sleeve drives the hexagonal rivet nut to move upward, the clamping arm clamps the head, and the limiting sleeve can prevent the hexagonal rivet nut from shaking.

[0014] Furthermore, the clamping part of the clamping arm has an arc-shaped clamping edge, which can better clamp the round head of the hexagonal rivet nut.

[0015] Furthermore, a slide block is installed on the side of the translation seat for mounting on the slide rail of the automatic riveting machine, so as to realize the horizontal movement of the translation seat.

[0016] The beneficial effects of this utility model are as follows: by rotating the sleeve, the inner hole of the sleeve matches the hexagonal sides of the hexagonal rivet nut. After the sleeve is reset, the angle rotation of the hexagonal rivet nut is completed. Regardless of the feeding angle, the angle can be unified, thereby achieving accurate positioning. This is beneficial for the subsequent automated material handling of the rivet gun, realizing fully automated continuous production and greatly improving production efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] See Figure 1 —— Figure 4 The hexagonal rivet nut angle adjustment device of this utility model includes: a bracket 1 and a sleeve 5. A feed pipe 2 is installed at the front end of the bracket 1. A horizontally movable clamping arm 4 is provided on the bracket 1. The sleeve 5 is located below the feed pipe 2 and can move horizontally or vertically.

[0025] This utility model includes a translation seat 11, which is equipped with a translation cylinder 16. The translation cylinder 16 drives the translation seat 11 to move horizontally. The translation seat 11 is equipped with a slide 15, which is used to fix it on the external transverse slide rail 20 to realize the translation of the translation seat 11.

[0026] The present invention has a translational seat 11 longitudinally mounted with a lifting cylinder 12 and a longitudinal slide rail 14. A lifting seat 13 is slidably mounted on the longitudinal slide rail 14. The lifting cylinder 12 drives the lifting seat 13 to rise and fall. A sleeve 5 is installed on the lifting seat 13.

[0027] The lifting seat 13 of this utility model is equipped with a sleeve seat 8, and a rotary cylinder 7 is installed on the side of the sleeve seat 8. The sleeve seat 8 is provided with a meshing rack 22 and a gear 23. The sleeve 5 is fixed in the middle of the gear 23. The rotary cylinder 7 drives the rack 22 to move. By driving the rack 22 to extend and retract through the rotary cylinder 7, the rotation angle of the sleeve 5 can be controlled.

[0028] The bracket 1 of this utility model has a horizontally arranged through hole, and a pressure plate 3 is movably disposed within the through hole, which is used to limit the movement of the pressure plate 3. The bracket 1 has a horizontal plate, with a finger cylinder 9 installed at the upper end and a pressure plate cylinder 17 installed at the lower end.

[0029] Among them, the finger cylinder 9 has a clamping arm 4, which is used to clamp the head of the hexagonal rivet nut 21. Furthermore, the clamping part of the clamping arm 4 has an arc-shaped clamping edge to clamp the round edge of the head of the hexagonal rivet nut 21.

[0030] The clamping part of the clamping arm 4 of this utility model is located below the feed pipe 2, and the clamping part is also located below the pressure plate 3.

[0031] The pressure plate cylinder 17 of this utility model is used to drive the pressure plate 3 to move. When the hexagonal rivet nut 21 falls into the sleeve 5, the pressure plate cylinder 17 drives the pressure plate 3 to extend. When the sleeve 5 moves upward, the pressure plate 3 blocks the hexagonal rivet nut 21 so that subsequent angular rotation can be performed.

[0032] The lifting seat 13 of this utility model has a lifting plate 6 below it. One end of the lifting plate 6 is connected to the telescopic rod of the lifting cylinder 12, and the sleeve seat 8 is installed on the right side of the lifting plate 6.

[0033] The bracket 1 of this utility model is equipped with a limiting cylinder 10 at its front end, and the limiting cylinder 10 is located below the feed pipe 2. The limiting cylinder 10 has a cylindrical through hole for the hexagonal rivet nut 21 to pass through, and at the same time for the sleeve 5 to rise and fall.

[0034] See Figure 4 This is a structural diagram of the present invention applied to an automatic riveting machine. The automatic riveting machine includes a mounting plate 18 and a riveting gun 19, which can be raised and lowered and moved.

[0035] A transverse slide rail 20 is mounted on the mounting plate 18, located next to the rivet gun 19. A hexagonal rivet nut angle adjustment device is slidably mounted on the transverse slide rail 20. The slide block 15 of the hexagonal rivet nut angle adjustment device is slidably mounted on the transverse slide rail 20. A translation cylinder 16 is fixedly mounted on the right side of the mounting plate 18.

[0036] The bracket 1 is fixedly installed on the mounting plate 18. The hexagonal rivet nut 21 is fed in through the feed pipe 2. After the sleeve 5 bears the rotation angle, the translation cylinder 16 drives the translation seat 11 to move horizontally along the transverse slide rail 20. This causes the sleeve 5 to move under the rivet gun 19 after bearing the hexagonal rivet nut 21. The rivet gun 19 picks up the nut and performs the riveting, ensuring that the angle of the hexagonal rivet nut 21 meets the preset requirements.

[0037] In operation, the hexagonal rivet nut 21 is automatically fed in, falls through the feed pipe 2, and after passing through the limiting cylinder 10, its lower end falls into the sleeve 5. The pressure plate cylinder 17 drives the pressure plate 3 to move, so that one end of the pressure plate 3 is located at the upper end of the limiting cylinder 10. The lifting cylinder 12 drives the lifting plate 6 to move upward, and the sleeve 5 is driven to move upward. The sleeve 5 passes through the limiting cylinder 10, and the head of the hexagonal rivet nut 21 is blocked by the pressure plate 3. The finger cylinder 9 drives the clamping arm 4 to clamp the hexagonal rivet nut 21. At the head, the hexagonal rivet nut 21 is positioned, and the lifting cylinder 12 continues to drive the sleeve 5 to move upward. At the same time, the rotary cylinder 7 drives the rack 22 to move, so that the gear 23 drives the sleeve 5 to rotate, thereby making the hexagonal sides of the hexagonal rivet nut 21 completely match the hexagonal inner hole of the sleeve 5, completing the sleeve 5 bearing the hexagonal rivet nut 21. The sleeve 5 returns to its original position downward, and is then driven by the translation cylinder 16 to move the sleeve 5 to below the rivet gun 19 for subsequent riveting production, realizing fully automated production.

[0038] This invention can drive the sleeve 5 to rotate by the rotary cylinder 7 to support the hexagonal rivet nut 21. After the rotary cylinder 7 drives the sleeve 5 to reset, the angle of the hexagonal rivet nut 21 is uniform, which is beneficial to the riveting of the rivet gun 19.

[0039] Of course, the above-described embodiments are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this utility model should be included within the scope of the claims of this utility model.
