Description

Technical Field

[0001] This utility model relates to the field of automotive parts riveting technology, specifically to a riveting device for a sunroof bracket connecting shaft. Background Technology

[0002] In the manufacturing process of automotive sunroof brackets, the riveting quality of the connecting shaft and the sunroof bracket directly affects the motion accuracy and reliability of the entire sunroof system.

[0003] The effectiveness of fixing the bracket and the connecting shaft in the riveting process directly affects the quality of the riveting. In the production of car sunroofs, the riveting process often uses contouring fixtures combined with handholds for fixing. However, the above fixing method has poor reliability. The workpiece is prone to displacement during the riveting process, which can lead to deviations or damage at the riveting part of the sunroof, affecting the quality of the product and even causing safety hazards.

[0004] Based on this, this utility model designs a riveting device for the connecting shaft of a sunroof bracket to solve the above problems. Utility Model Content

The shaft limiting hole 263 is used to fix the upper end of the sunroof connecting shaft 6 to complete the pressing action during riveting.

[0036] like Figure 1 and Figure 3 As shown, the connecting shaft fixing mechanism 4 includes a shaft placement block 41, a shaft placement groove 42, and a shaft fixing assembly 43. The lower end of the shaft placement block 41, located above the right support block 313 of the bracket, is fixedly connected to the base 1. The shaft placement block 41 is fixedly connected to the right support block 313 of the bracket. The shaft placement block 41 is provided with a shaft placement groove 42 for accommodating the sunroof connecting shaft 6. The shaft fixing assembly 43 is connected to the right end of the shaft placement block 41.

[0037] The shaft fixing assembly 43 includes a shaft push block 431, a push block groove 432, a shaft cylinder 433, and a connecting block 434. One side of the L-shaped connecting block 434 is fixedly connected to the shaft placement block 41, and the other side of the connecting block 434 is fixedly connected to the housing of the shaft cylinder 433. The output end of the shaft cylinder 433 is fixedly connected to the shaft push block 431. A push block groove 432 is provided on the shaft placement block 41 to accommodate the shaft push block 431. The push block groove 432 allows the shaft push block 431 to move only left and right in the horizontal direction. The shaft push block 431 is used to fix the sunroof connecting shaft 6 placed in the shaft placement groove 42.

[0038] In this invention, the sunroof bracket 5 is placed on the left support block 311 and the right support block 313 of the bracket. The front protrusion 52 is placed in the right limiting hole 314, and the rear protrusion 53 is placed in the left limiting hole 312. The sunroof connecting shaft 6 is passed through the shaft placement groove 42 on the shaft placement block 41 and aligned with the riveting hole 54. The specific riveting support structure ensures the reliability of fixing the sunroof bracket 5 by limiting the positions of the front protrusion 52 and the rear protrusion 53. The shaft cylinder 433 on the connecting block 434 is activated, and the shaft cylinder 433 pushes the shaft push block 431 to move. Under the limiting action of the push block slide groove 432, the shaft push block 431 can only move horizontally to the left. Through the cooperation of the shaft push block 431 and the shaft placement groove 42, the sunroof connecting shaft 6 is fixed in the shaft placement groove 42, so that the position of the sunroof connecting shaft 6 will not shift, thus ensuring the reliability of riveting the sunroof bracket 5 and the sunroof connecting shaft 6.

[0039] Start the double-rod cylinder 331 on the fixing block 333. The double-rod cylinder 331 pushes the fixing push block 332 to move horizontally to the left, pressing the right end of the sunroof bracket 5 against the left end of the right support block 313 of the bracket. Start the corner cylinder 321. The corner cylinder 321 drives the pressure rod 322 to rotate above the upper protrusion 51 and press down. The sunroof bracket 5 is fixed by this method, so that the position of the sunroof bracket 5 will not shift during the riveting process.

[0040] When the hydraulic cylinder 21 on the top plate 22 is activated, the top plate 22 will not move under the support of the support rod 23. The hydraulic cylinder 21 pushes the vertical moving plate 24 downward, which in turn drives the upper limit pressure rod 251, the upper pressure block 252, the lower pressure block 261, and the lower pressure column 262 downward. The lower pressure column 262 cooperates with the shaft limit hole 263 to press down and rivet the sunroof connecting shaft 6. The upper limit pressure rod 251 and the upper pressure block 252 move downward until the upper pressure block 252 enters the lower limit pressure rod. In the limiting pressure hole 254 of 253, the limiting pressure rod 253 limits the maximum pressing distance and also has a certain guiding and directing function. After the riveting is completed, the hydraulic cylinder 21 resets and drives the pressing column 262 to reset, the shaft cylinder 433 resets and drives the shaft push block 431 to reset, the corner cylinder 321 resets and drives the pressure rod 322 to reset, and the double rod cylinder 331 resets and drives the fixed push block 332 to reset. Take out the riveted sunroof bracket 5 and sunroof connecting shaft 6, and repeat the above operation.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
