Abstract
Description
Technical Field
[0001] This utility model relates to the field of riveting machine technology, specifically a precision positioning device for a riveting machine. Background Technology
[0002] The precision positioning device of a riveting machine is a key system to ensure that rivets are accurately and consistently riveted to the predetermined positions on the workpiece. Its core objectives are to achieve high precision, high repeatability, and high efficiency. In a handheld self-piercing riveting machine, a die hole is set in the center of the base plate, and the two clamping plates are connected by a bidirectional lead screw. Rotating the lead screw synchronously drives the clamping plates to move towards the center, achieving symmetrical clamping of the sheet metal. After clamping, the workpiece is difficult to remove due to the obstruction of the positioning structure, and it is prone to wear due to friction with the positioning structure during removal, exhibiting certain shortcomings. Therefore, we propose a precision positioning device for a riveting machine. Utility Model Content
[0003] The present invention aims to solve the problems existing in the prior art or related technologies.
[0004] Therefore, the technical solution adopted by this utility model is as follows: a precision positioning device for a riveting machine, including a positioning seat, a drive assembly, a clamping rod, a positioning component, and an ejection assembly. The positioning seat has an insertion hole and a sliding groove on its inner side. The drive assembly is fixedly installed at the bottom of the positioning seat. The clamping rod is threadedly connected to the drive assembly. The positioning component includes a spring fixedly installed inside the positioning seat, a positioning block fixedly installed on the right side of the spring, and an inclined surface installed on the right side of the positioning block. The ejection assembly includes a mounting plate inserted into the sliding groove, a cylinder fixedly installed on the mounting plate, a fixing plate inserted into the top of the cylinder, a top plate abutting against the top of the fixing plate, and an inclined block fixedly installed on the outer side of the top plate.
[0005] Preferably, the top of the positioning seat is provided with several rivet slots for placing rivets, and both sides of the positioning seat are fixedly provided with gaskets, and each of the two gaskets is provided with mounting holes.
[0006] Preferably, the drive assembly includes a drive motor fixedly mounted at the front end of the positioning seat and a lead screw fixed to the output end of the drive motor, wherein the front and rear portions of the outer side of the lead screw are provided with external threads in different directions.
[0007] Preferably, there are two positioning elements, which are symmetrically distributed on the positioning base.
[0008] Preferably, a circular hole is provided in the middle of the fixing plate, and two positioning posts are fixedly provided at the top of the fixing plate.
[0009] Preferably, both top plates have positioning grooves at their bottom ends, and the positioning grooves are interlocked with the corresponding positioning posts.
[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: The cylinder of this utility model can drive the top plate to move upward through the fixed plate, thereby ejecting the processed workpiece. This avoids the positioning structure blocking the user from taking out the workpiece, saving time and effort. At the same time, when the top plate moves upward, it can drive the inclined block. Due to the elasticity of the spring, the inclined block can cooperate with the inclined surface to push away the positioning block, avoiding friction and wear between the positioning block and the workpiece, so as to remove the material without damage. Then, the sliding groove allows the mounting plate to be installed on the positioning seat, and the round hole allows the cylinder to be inserted into the fixed plate. The cooperation of the positioning groove and the positioning column allows the top plate to be installed on the fixed plate, realizing a combination, without the need for screws or other structural fixation, and can be quickly installed and disassembled for maintenance of the ejection component.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0025] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a precision positioning device for a riveting machine.
[0026] Example 1:
[0027] Reference Figure 1-7 This is the first embodiment of the present invention. This embodiment provides a precision positioning device for a riveting machine, including a positioning seat 100, a drive assembly 200, a clamping rod 300, a positioning element 400, and an ejection assembly 500.
[0028] Specifically, the positioning seat 100 has an insertion hole 102 and a sliding groove 105 on its inner side. The top of the positioning seat 100 has several rivet slots 101 for placing rivets. Both sides of the positioning seat 100 are fixedly provided with washers 103, and both washers 103 have mounting holes 104. In use, the top plate 504 can be inserted into the positioning seat 100 through the insertion hole 102, and the mounting plate 501 can be inserted into the positioning seat 100 through the sliding groove 105 to install the ejector assembly 500. Then, rivets can be placed through the rivet slots 101 to fix the workpiece. The washers 103 can increase the area of the positioning seat 100 to fix the positioning seat 100.
[0029] Specifically, the drive assembly 200 is fixedly installed at the bottom of the positioning seat 100. The drive assembly 200 includes a drive motor 201 fixedly installed at the front end of the positioning seat 100 and a lead screw 202 fixed to the output end of the drive motor 201. The front and rear parts of the outer side of the lead screw 202 are provided with external threads in different directions. In use, the drive motor 201 can drive the lead screw 202 to rotate. The rotating lead screw 202 can drive the two clamping rods 300 to clamp the workpiece for positioning.
[0030] Specifically, the clamping rods 300 are threaded onto the drive assembly 200. In use, the two clamping rods 300 can clamp and position the workpiece for processing.
[0031] Specifically, the positioning element 400 includes a spring 401 fixedly disposed inside the positioning seat 100, a positioning block 402 fixedly disposed on the right side of the spring 401, and an inclined surface 403 disposed on the right side of the positioning block 402. There are two positioning elements 400, which are symmetrically distributed on the positioning seat 100. In use, the elasticity of the spring 401 allows the positioning block 402 to move so that the inclined block 505 can push the positioning block 402, and the positioning block 402 can be positioned for processing. Then, the inclined surface 403 can cooperate with the inclined block 505 to push the positioning block 402 open.
[0032] Specifically, the ejector assembly 500 includes a mounting plate 501 inserted into the slide groove 105, a cylinder 502 fixedly mounted on the mounting plate 501, a fixing plate 503 inserted into the top of the cylinder 502, a top plate 504 abutting against the top of the fixing plate 503, and an inclined block 505 fixedly mounted on the outside of the top plate 504. A circular hole 5031 is provided in the middle of the fixing plate 503, and two positioning posts 5032 are fixedly mounted on the top of the fixing plate 503. Positioning grooves 504 are provided at the bottom ends of both top plates 504. 1. The positioning groove 5041 is inserted and connected to the corresponding positioning post 5032. In use, the top of the cylinder 502 can be inserted into the fixed plate 503 through the round hole 5031. The top plate 504 can be installed on the fixed plate 503 through the cooperation of the positioning groove 5041 and the positioning post 5032. Then, the cylinder 502 can drive the fixed plate 503 and the top plate 504 to move upward so as to push out the workpiece. At the same time, the inclined block 505 can push the positioning part 400 away to avoid the positioning part 400 from rubbing against the workpiece and wearing out.
[0033] The working principle and usage process of this utility model are as follows: In use, first align the mounting plate 501 of the ejector assembly 500 with the slide groove 105, and then insert it. Then move the mounting plate 501 to the middle position of the positioning seat 100. Next, align the round hole 5031 of the fixing plate 503 with the top of the cylinder 502 and insert it. After insertion, align the two top plates 504 with the insertion hole 102 and insert them. After insertion, align the positioning grooves 5041 of the two top plates 504 with the positioning posts 5032 on the fixing plate 503, and then insert them to fix the ejector assembly 500. Then, the cylinder 502 can be extended. The extended cylinder 502 can drive the top plate 504 to move upward through the fixing plate 503. The moving top plate 504 can eject the workpiece. At the same time, the top plate 504 will drive the inclined block 505 to move. The moving inclined block 505 will push the positioning block 402 outward.
