[0028] By the above arrangement, the riveting process is divided into two stages. First, the riveting assembly drives the slide plate assembly and the release structure for placing the first workpiece to move synchronously, so as to make the first workpiece close to the second workpiece, thereby reducing the distance between them and avoiding the difficulty in aligning due to the large distance between the first workpiece and the second workpiece, which affects the riveting buckling. When the slide plate assembly moves to a position where the first workpiece and the second workpiece are close enough, the riveting assembly continues to move along the riveting direction while the slide plate assembly stops moving, so as to leave enough impact buckling space between the first workpiece and the second workpiece. The riveting assembly and the slide plate assembly slide relative to each other to impact the first workpiece and the second workpiece to complete the buckling, thereby ensuring the alignment effect and reducing the generation of unqualified products.

[0029] In the riveting machine of the embodiment, the riveting mechanism comprises a linkage assembly for realizing the linkage movement of the riveting assembly and the slide plate assembly. During the movement of the riveting assembly along the riveting direction, the linkage assembly drives the slide plate assembly to move along the riveting direction, so as to make the first workpiece close to the second workpiece matched with the first workpiece.

[0030] Specifically, the slide plate assembly is clamped between the riveting assembly and the linkage assembly, and the linkage assembly pushes and tightens the slide plate assembly and the riveting assembly to realize the linkage of the two, so as to drive the slide plate assembly and the release structure to move when the riveting assembly moves, and make the first workpiece close to the second workpiece for subsequent buckling.

[0031] The riveting machine of the embodiment comprises a linkage assembly, a friction plate 1 for realizing friction contact between the riveting assembly and the sliding plate assembly, and a first elastic member for pushing the friction plate 1 to realize friction contact.

[0033] Preferably, the sliding plate assembly comprises a first sliding plate 3, the riveting assembly comprises a first clamping sleeve 4, the first compression spring 2 and the friction plate 1 are located on the side of the first sliding plate 3 away from the first clamping sleeve 4, the first compression spring 2 pushes the friction plate 1 to realize friction contact with the first sliding plate 3 so as to drive the first clamping sleeve 4 to move in linkage with the first sliding plate 3.

[0036] The riveting machine of the embodiment further comprises a guiding assembly for guiding the sliding plate assembly and a limiting assembly for limiting the movement of the sliding plate assembly, the sliding plate assembly is installed on the guiding assembly, and after the riveting assembly drives the sliding plate assembly to move along the guiding assembly to the position where the first workpiece approaches the second workpiece, the sliding plate assembly stops moving under the action of the limiting assembly.

[0037] The guide assembly provides support and guidance for the first slide plate 3, and the limiting assembly divides the riveting stroke of the first riveting punch into two parts. Before the slide plate assembly contacts the limiting assembly, the first slide plate 3 moves synchronously with the first riveting punch through the tightening action of the first compression spring 2 and the friction between the friction plate 1 and the first slide plate 3, so that the first workpiece in the release structure on the first slide plate 3 approaches the second workpiece, facilitating alignment for riveting.

[0038] Specifically, the limiting assembly includes a first limiting piece arranged on the slide plate assembly and a second limiting piece arranged on the guide assembly. After the riveting assembly drives the slide plate assembly to move along the guide assembly to approach the second workpiece, the slide plate assembly stops moving under the cooperation of the first limiting piece and the second limiting piece.

When the first riveting punch drives the first clamping sleeve 4 to move downward, the friction plate 1 drives the first slide plate 3 and the limiting strip 7 to move downward in the first guide rail 6 until the limiting strip 7 abuts against the limiting block 8. The first slide plate 3 is limited, and the first riveting punch continues to move to drive the fixed rod 5 and the friction plate 1 to slide relative to the first slide plate 3. The first clamping sleeve 4 moves to the bottom of the first slide plate 3, and the first riveting punch impacts the first workpiece and the second workpiece for buckling.

[0042] Preferably, the first guide rail 6 includes two guide plates 18 symmetrically arranged relative to the first slide plate 3. The limiting block 8 is provided with two limiting blocks 8, and the two limiting blocks 8 are oppositely arranged on the inner side of the guide plates 18. The limiting strip 7 slides between the two guide plates 18 until it contacts the two limiting blocks 8.

[0043] In the riveting machine of the embodiment, the release structure is specifically a flap assembly, which includes two flaps 9 for placing the first workpiece.

When the riveting assembly impacts the flaps 9, the flaps 9 are driven to rotate, and at the same time, the first workpiece falls down and aligns with the second workpiece.

[0044] Preferably, the release structure is located at the bottom of the slide plate assembly. Through the movement of the slide plate assembly, the first workpiece in the release structure approaches the second workpiece as much as possible, so as to shorten the alignment distance and realize alignment and subsequent riveting buckling.

[0046] In the riveting machine of the embodiment, the joint of the two flaps 9 is provided with a placing groove 10 for placing the first workpiece, and the placing groove 10 is conical. When the flap 9 is flipped by the impact of the riveting assembly, the first workpiece slides downward along the inner wall of the placing groove 10 until it is separated from the placing groove 10 and aligned with the second workpiece.

[0047] Specifically, the two flaps 9 are horizontal in the initial state, and a joint gap is formed between the two flaps 9. The placing groove 10 includes two half grooves respectively formed on the two flaps 9. The first riveting punch vertically impacts the flaps 9 on both sides from the joint of the two flaps 9, and the two flaps 9 are flipped downward and gradually away from each other. The conical placing groove 10 slides relative to the edges of the first workpiece on both sides in the process of being opened by the flap 9, and guides the first workpiece through the arc-shaped groove surface, so that the first workpiece remains stable in the vertical direction before the flap 9 is completely opened, thereby avoiding the rotation of the first workpiece after the first workpiece is separated from the placing groove 10 and aligned with the second workpiece.

[0048] Specifically, the placing groove 10 includes a feeding groove 19 and a guide groove 20. The feeding groove 19 is connected to the first workpiece feeding channel. The first workpiece falls into the guide groove 20 after entering the feeding groove 19 through the feeding channel.

The two flaps 9 are rotatably connected to the connecting seat 21 on the side away from each other. A torsional spring is further arranged between the flap 9 and the connecting seat 21 to facilitate the resetting of the flap 9. After completing a riveting, the first riveting punch and the first clamping sleeve 4 move upward to reset the first slide plate 3 and the connecting seat 21 by cooperating with the first compression spring 2 and the friction plate 1 to clamp the first slide plate 3, until the connecting seat 21 abuts against the first guide rail 6 to limit the first slide plate 3. Then, the first clamping sleeve 4 drives the friction plate 1 to slide relative to the first slide plate 3, and the first clamping sleeve 4 moves to the top end of the first slide plate 3 to complete the resetting.

[0050] Specifically, the connecting seat 21 is provided with a feeding port matched with the first workpiece feeding channel, and the bottom end of the first slide plate 3 is provided with a groove matched with the feeding port to facilitate the first workpiece to enter the placing groove 10.

[0051] Preferably, the angle of rotation of the flap 9 and the height difference before and after rotation match the distance between the first workpiece and the second workpiece when the first slide plate 3 stops moving, improving the alignment effect of the first workpiece and the second workpiece, and ensuring that the first workpiece is immediately engaged with the second workpiece after leaving the placement groove 10.

[0052] Further preferably, the depth of the placement groove 10 is greater than the thickness of the flap 9, i.e. there is an extension 22 integrally formed at the bottom of the flap 9, ensuring that the placement groove 10 has sufficient depth to guide the first workpiece, while reducing the material used for the flap 9, avoiding excessive weight of the flap 9 affecting normal flipping, and improving practicality.
