Technical Field
[0001] This utility model relates to the field of seat belt manufacturing technology, and in particular to a seat belt buckle rivet positioning mechanism. Background Technology
[0002] Currently, when riveting seat belt buckle rivets into the frame, the frame is usually first placed in a flexible fixture and automatically clamped using a pneumatic clamp; then the rivet is automatically driven to the bottom of the rivet head, and the rivet head is driven down to complete the riveting. However, because the large and small ends of the seat belt buckle rivet may not be concentric after one end is riveted or cast, rigid riveting can easily lead to eccentricity and prevent it from being properly inserted into the frame hole.
[0003] Therefore, it is necessary to design a seat belt buckle rivet positioning mechanism to solve the above problems. Summary of the Invention
[0004] The purpose of this utility model is to propose a seat belt buckle rivet precision positioning mechanism, which can achieve precise centering and clamping of the rivet, thereby ensuring that the rivet can be accurately inserted into the skeleton hole.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0031] like Figures 1 to 5 As shown, a seat belt buckle rivet positioning mechanism includes a positioning base 1, a first clamping block 2, a second clamping block 3, and a driving assembly 4.

[0032] Specifically, in this embodiment, as follows: Figure 2As shown, the positioning base 1 is rectangular; the positioning base 1 has an upper through groove 51 and a lower through groove 52 arranged vertically and parallel to the first direction. The upper through groove 51 passes through the top surface of the positioning base 1 through the first channel 53, and the upper through groove 51 and the lower through groove 52 are connected by the second channel 54; wherein, the lower through groove 52, the first channel 53 and the second channel 54 form a first clamping block slide; the upper through groove 51 and the first channel 53 form a second clamping block slide.
[0033] In this embodiment, as Figure 3 As shown, the first clamping block 2 includes a first clamping part 21 and a first sliding part 22 connected to the first clamping part 21; the first sliding part 22 is slidably disposed in the slide rail of the first clamping block, and the first clamping part 21 is slidably disposed on the top surface of the positioning seat 1, and has a first slot 23. The second clamping block 3 includes a second clamping part 31 and a second sliding part 32 connected to the second clamping part 31; the second sliding part 32 is slidably disposed in the slide rail of the second clamping block, and the second clamping part 31 is slidably disposed on the top surface of the positioning seat 1, and has a second slot 33.
[0034] In use, after the rivet 10 is placed in the positioning groove 11, the drive assembly 4 drives the first clamping block 2 and the second clamping block 3 to move toward the center of the positioning groove 11, thereby clamping the rivet 10 in the positioning groove 11 through the first slot 23 and the second slot 33.
[0035] It should be noted that in this embodiment, different specifications and models of products can be adapted by replacing the first clamping block 2 and the second clamping block 3.
[0036] In this embodiment, as Figure 3 As shown, the drive assembly 4 includes a first positioning shaft 41 and a second positioning shaft 42 arranged vertically, two connecting plates 43 and a drive component 44.
[0037] In the drive assembly 4, the first positioning shaft 41 is connected to the first clamping block 2, and the second positioning shaft 42 is connected to the second clamping block 3. The central axis of the first positioning shaft 41 and the second positioning shaft 42 is set perpendicular to the first direction. The first positioning shaft 41 is slidably disposed in the first guide groove 12 opened along the first direction on the positioning seat 1. The second positioning shaft 42 is slidably disposed in the second guide groove 13 opened along the first direction on the positioning seat 1.
[0038] In the drive assembly 4, two connecting plates 43 are rotatably connected to both sides of the positioning seat 1, and the two ends of the connecting plates 43 are respectively provided with a first sliding groove 431 and a second sliding groove 432, such as Figure 4As shown. The first slide groove 431 and the second slide groove 432 are symmetrically arranged with respect to the rotation center of the connecting plate 43. The end of the first positioning shaft 41 is slidably disposed within the first slide groove 431, and the end of the second positioning shaft 42 is slidably disposed within the second slide groove 432.
[0039] In this drive assembly 4, the drive end of the drive member 44 is connected to the first clamping block 2. The drive member 44 is preferably a cylinder.
[0040] Furthermore, the first clamping block 2 is connected to a third positioning shaft 45 arranged perpendicular to the first direction; the third positioning shaft 45 is slidably disposed in a third guide groove 14 opened along the first direction on the positioning seat 1; the third guide groove 14 is located between the first guide groove 12 and the second guide groove 13. The lengths of the first guide groove 12, the second guide groove 13 and the third guide groove 14 are the same.
[0041] When centering and clamping the rivet 10 located in the positioning groove 11, the driving member 44 drives the first clamping block 2 to move along the first clamping block slide towards the center of the positioning groove 11. The first positioning shaft 41 slides and engages with the first guide groove 12 and the first slide groove 431, causing the two connecting plates 43 to rotate relative to the positioning seat 1. The second positioning shaft 42 slides and engages with the second guide groove 13 and the second slide groove 432, causing the second clamping block 3 to move along the second clamping block slide towards the center of the positioning groove 11.

A push rod 61 is slidably disposed in the through hole 111, and the push rod 61 is connected to a lifting drive component 62 that drives it to move up and down. The lifting drive component 62 is preferably a cylinder.
[0043] After the rivet 10 is riveted to the skeleton, the drive assembly 4 drives the first clamping block 2 and the second clamping block 3 to move in opposite directions, thereby releasing the clamp on the rivet 10; the lifting drive 62 drives the push rod 61 to move upward, thereby pushing out the riveted product. In this embodiment, because the lifting drive 62 and the push rod 61 cooperate to push out the riveted product, it can avoid scratching the product when picking up the material.
[0044] Furthermore, a fourth guide groove 34 is provided on the second clamping block 3 along the first direction, and the push rod 61 is slidably disposed in the fourth guide groove 34.
[0045] This utility model discloses a precision positioning mechanism for seat belt buckles and rivets. In use, the rivet 10 is placed in the positioning groove 11; the driving component 4 drives the first clamping block 2 and the second clamping block 3 to move towards the center of the positioning groove 11, thereby centering and clamping the rivet 10. The frame is then placed on the positioning seat 1, and the rivet 10 is inserted into the frame hole for riveting. After riveting, the driving component 4 drives the first clamping block 2 and the second clamping block 3 to move away from the center of the positioning groove 11, thereby releasing the clamping of the rivet 10; the lifting driving component 62 drives the lifting rod 61 to move upward, thereby ejecting the product. This precision positioning mechanism for seat belt buckles and rivets achieves precise centering and clamping of the rivet 10, ensuring that the rivet 10 can be accurately inserted into the frame hole. It has a simple structure, high riveting accuracy and efficiency, and strong applicability.
