The above-mentioned riveting machine places the product on the upper surface of the receiving plate through the receiving plate fixedly installed on the upper surface of the frame, and can effectively fix and process products of different sizes through the telescopic cooperation of the slide groove and the rod, which can improve the adaptability of the device.

[0004] However, when the above-mentioned riveting machine completes the riveting, the rivet head does not stop immediately, and the operator needs to quickly remove the workpiece to achieve higher production efficiency. However, the continuously rotating rivet head and the workpiece are on the same axis. If the workpiece is to be removed, the workpiece needs to be moved toward the rivet head first, so the operator needs to quickly complete such a dangerous and delicate operation in an already narrow space. Similarly, the same is true when the operator continuously loads samples. The design of the above-mentioned riveting machine cannot solve or avoid the above-mentioned safety hazards.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a fully automatic shrinkable riveting machine, such as Figure 1-5As shown, the shrinkable riveting machine includes a base 1, a bracket 11 fixedly mounted on the base 1, and a guide frame 12 fixed on the bracket 11, a riveting machine body 13 is arranged in the guide frame 12, a slide groove 14 is provided on the base 1, a placing table 15 is slidably installed in the slide groove 14, a first rack 21 is movably arranged in the bracket 11, a mounting block 22 is fixedly mounted between the first rack 21 and the riveting machine body 13, and a gear meshing with the first rack 21 is rotatably installed in the bracket 11 23, a second rack 25 meshing with the gear 23 is movably provided in the bracket 11, a connecting rod 26 is hinged at one end of the second rack 25 close to the base 1, the other end of the connecting rod 26 is hinged to the placement table 15, a clamping mechanism 3 is provided on the placement table 15, a first guide groove 2 is provided in the bracket 11, the first rack 21 is slidably installed on the first guide groove 2, a second guide groove 24 is provided in the bracket 11, the second rack 25 is slidably installed on the second guide groove 24.

[0028] When in use, after the workpiece is riveted, the riveting machine body 13 will reset upward and move a distance, at which time it will drive the mounting block 22 and the first rack 21 to move upward along the first guide groove 2. The first rack 21 is initially in a state of not meshing with the gear 23. Therefore, when the riveting machine body 13 just starts to move, it will not link other parts to move. When the riveting machine body 13 is lifted to a safe position and the workpiece is released, the teeth of the first rack 21 begin to mesh with the gear 23, driving the gear 23 to rotate while further driving the second rack 25 to move downward along the second guide groove 24. The bottom of the second rack 25 pushes the connecting rod 26 toward the placement table 15. The first rack 25 moves upward to drive the placement table 15 to reset to the working position. When resetting, after all the teeth on the first rack 21 pass the position of the gear 23, the first rack 21 continues to move downward with the riveting machine body 13 and cannot drive the gear 23 to rotate. Therefore, the position of the placement table 15 is fixed, and the riveting machine body 13 can continue to move downward alone to contact the workpiece for riveting operation.

[0029] Specifically, the clamping mechanism 3 includes a rotating disk 31 rotatably mounted on the placement table 15, a limiting disk 32 fixedly mounted on the placement table 15, and a plurality of clamping arms 33 arranged on the limiting disk 32, the rotating disk 31 is provided with a plurality of third guide grooves 311 distributed in a circular array, the limiting disk 32 is provided with a plurality of limiting grooves 321 corresponding to the third guide grooves 311, the end of the clamping arm 33 away from the riveting machine body 13 is provided with a sliding rod 331 slidably matched with the third guide groove 311, the clamping arm 33 is provided with a limiting block 332 slidably matched with the limiting groove 321, the placement table 15 is provided with a rotating disk 311, and the limiting disk 32 is provided with a plurality of third guide grooves 311 distributed in a circular array, and the limiting disk 32 is provided with a plurality of limiting grooves 321 corresponding to the third guide grooves 311. The third guide groove 311 drives the slide bar 331 to move radially outward, and the limit plate 32 is fixed to the placement table 15 and will not rotate. The clamping arm 33 maintains radial movement limited by the limit groove 321 under the cooperation of the limit block 332 and the limit groove 321, and the workpiece can be released. Similarly, when the rotating disk 31 rotates counterclockwise, the clamping arm 33 can clamp the workpiece. The clamping arm 33 is provided with a plurality of arms, which move toward the center of the circle at the same time as the rotating disk 31, so as to ensure that the workpiece and the riveting machine body 13 always keep the same axis, thereby ensuring correct riveting.

[0030] Furthermore, a fixing plate 4 is fixedly mounted on the base 1, and a plurality of springs 41 are fixedly arranged on the fixing plate 4. The other end of the spring 41 is fixedly connected to a third rack 42, and the rotating disk 31 is provided with teeth 312 meshing with the third rack 42. When the riveting is completed, the placement table 15 moves outward, and at this time, the teeth 312 arranged around the rotating disk 31 mesh with the third rack 42. Since the position of the third rack 42 is fixed by the fixing plate 4, the rotating disk 31 will be driven to rotate clockwise to release the clamp. When the operator replaces a new workpiece, he only needs to place it in the clamping mechanism 3, and the workpiece can be automatically clamped during the resetting process of the placement table 15. After completing the processing of the same batch of workpieces, when it is necessary to replace workpieces of different specifications for further processing, he only needs to push the third rack 42 toward the fixed plate 4, release the rotating disk 31, place the workpiece in the working position of the placement table 15, rotate the rotating disk 31 to clamp it, and then release the third rack 42 to resume meshing. At this time, the clamping mechanism 3 can be adapted to the clamping and loosening processes of workpieces of different specifications.

[0031] It should be noted that the clamping end of the clamping arm 33 is in a concave arc shape, the concave end of the clamping arm 33 is provided with a plurality of convex bumps, the third guide groove 311 is an arc groove, the limit plate 32 is coaxially arranged with the rotating plate 31, and the connecting rod 26 is a telescopic rod.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
