[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference below Figure 1-2 , the implementation of the rivet point structure proposed in the embodiment of the utility model is described in detail.

[0026] The riveting point structure according to the embodiment of the utility model comprises: a three-jaw chuck 1 and a riveting point device 2.

[0027] Specifically, the three-jaw chuck 1 has a handle 1 and a jaw 12, and the riveter 2 is adjustably arranged on the jaw 12 along its axial direction. When the handle 1 is rotated, the jaw 12 drives the riveter 2 to move toward the clamping center of the jaw 12, so that the riveter 2 rivets the workpiece.

[0028] That is to say, the operator rotates the handle 1 to make the claws 12 move synchronously toward the clamping center, thereby driving multiple riveting devices 2 to rivet multiple positions of the workpiece. Multiple riveting points can be riveted at one time with high efficiency and uniform distribution of the riveting points.

[0029] Therefore, by providing the riveting device 2 on the clamping jaw 12 of the three-jaw chuck 1, the clamping jaw 12 synchronously drives the riveting device 2 to move toward the workpiece to be riveted and abut against the workpiece, thereby riveting the workpiece evenly and efficiently.

[0030] For the auxiliary clamping of the workpiece, an auxiliary part 3 is also included. The auxiliary part 3 can be elastically and telescopically arranged on the clamping claw 12 to follow the clamping claw 12 to move toward the clamping center and elastically abut the workpiece to be riveted. It can be understood that by elastically and telescopically setting the auxiliary part 3 on the clamping claw 12, it is convenient for the clamping claw 12 to drive the auxiliary part 3 to approach and abut the surface of the workpiece to be riveted. Since the auxiliary part 3 can be elastically and telescopically arranged, it can position the workpieces to be riveted of different sizes at the clamping center, thereby facilitating the subsequent riveting of the workpiece by the riveting device 2. At the same time, it is convenient for the operator to operate with one hand, which can avoid the risk of the operator's hand being clamped by the riveting device 2 or the clamping claw 12, and ensure the operator's operation safety.

[0031] For the installation of the auxiliary component 3, the claw 12 is provided with a first installation hole 131, and the auxiliary component 3 can be elastically and telescopically inserted into the first installation hole 131. It can be understood that the first installation hole 131 is provided to facilitate the auxiliary component 3 to be installed in coordination with the first installation hole 131, so as to facilitate the auxiliary component 3 to be restricted in the first installation hole 131 for telescopic movement, so that the auxiliary component 3 is not prone to axial displacement, and has a better clamping and positioning effect for workpieces of different sizes. Among them, the first installation hole 131 can be a square hole, and the matching part between the auxiliary component 3 and the first installation hole 131 can be set as a square rod.

[0032] As for the auxiliary part 3, the auxiliary part 3 has an abutment portion 31 suitable for abutting the workpiece, and the abutment portion 31 is in an arc shape. It can be understood that the arc-shaped setting of the abutment portion 31 can facilitate better clamping and positioning of the pin and shaft to be riveted, so that the riveting point position of the workpiece is more accurate. Among them, the abutment portion 31 can be integrally formed on the auxiliary part 3, the first mounting hole 131 can be a square hole, and the matching part of the auxiliary part 3 and the first mounting hole 131 can be set as a square rod, and the square hole and the square rod can be matched to prevent the abutment portion 31 from rotating along its axis.

[0033] For the elastic expansion and contraction of the auxiliary component 3, the auxiliary component 3 also includes a spring 32, which is sleeved on the auxiliary component 3, one end of the spring 32 abuts against the abutting portion 31, and the other end of the spring 32 abuts against the claw 12. It can be understood that the abutting portion 31 is kept in an extended state by the arrangement of the spring 32. When the abutting portion 31 abuts against the workpiece, the abutting portion 31 contracts as the claw 12 further approaches the workpiece, and at the same time, an elastic clamping force is maintained on the workpiece, which is convenient for clamping and positioning the workpiece, and has a simple structure and a good clamping and positioning effect. Among them, a detachable limit block 33 can be set at the opposite end of the abutting portion 31 to facilitate limiting the maximum distance that the abutting portion 31 extends. At the same time, the detachable arrangement of the limit block 33 can facilitate the installation of the auxiliary component 3 in the first mounting hole 131.

[0034] For the installation of the riveting device 2, the claw 12 is provided with a second mounting hole 132, and the riveting device 2 is inserted into the second mounting hole 132. The second mounting hole 132 is provided to facilitate the installation of the riveting device 2, so that the riveting device 2 has sufficient matching space to strengthen the restriction and support of the riveting device 2, thereby facilitating better riveting of the workpiece. The second mounting hole 132 may be a circular hole.

[0035] For the adjustment of the riveting device 2, the riveting device 2 is provided with a threaded section 21, and the threaded section 21 is threadedly matched with the second mounting hole 132 to adjust the riveting device 2 to be close to or away from the workpiece. It can be understood that the threaded section 21 of the riveting device 2 is arranged to facilitate the threaded connection between the riveting device 2 and the second mounting hole 132, thereby facilitating the adjustment of the extension length of the riveting device 2, so that each riveting device 2 applies a uniform top force to the workpiece, making the riveting points more uniform. Among them, the position where the riveting device 2 contacts the workpiece can be made of tungsten steel, and the tungsten steel material is connected to a bolt, and the bolt head can be rotated by a wrench during adjustment.

[0036] In addition, the three-jaw chuck 1 further includes a connecting block 13, which is connected to the top of the clamping jaw 12, and the riveting device 2 and the auxiliary component 3 are arranged on the connecting block 13. The connection block 13 is arranged to facilitate the processing of the first mounting hole 131 and the second mounting hole 132, and to avoid the trouble of disassembly and assembly caused by removing the clamping jaw 12 to process the first mounting hole 131 and the second mounting hole 132. The connecting block 13 can be welded or locked to the clamping jaw 12 after the first mounting hole 131 and the second mounting hole 132 are processed.
