According to the width of the automobile aluminum profile component, the second fixed plate 42 is driven to move forward and backward by the output end of the translation cylinder 41, and then the second fixed plate 42 drives the baffle 44 to move through the connecting frame 43, so that the position of the baffle 44 can be adjusted conveniently, and it is convenient to use with automobile aluminum profile components of different sizes.

[0030] A long groove 2 is symmetrically arranged at the upper end of the workbench 1, and a clamping mechanism 5 is installed at the lower end of the workbench 1. The clamping mechanism 5 includes a servo motor 51, a screw rod 52, a threaded block 53, an L-shaped rod 54 and a clamping assembly 55.

The inner cavity of the concave cover 551 is equidistantly provided with mutually contacting clamps 552. One side of the clamps 552 extends to the outside of the concave cover 551. One side of the clamps 552 is bonded with a rubber strip 553. One side of the rubber strip 553 is in an arc shape.

[0032] The output end of the servo motor 51 drives the screw rod 52 to rotate, and the screw rod 52 is a forward and reverse thread screw rod, so that the two threaded blocks 53 on the outer side thereof pass through the long slot 2 to drive the clamping assembly 55 to move in the same direction, and then the multiple clamping plates 552 in the clamping assembly 55 move toward the two sides of the automotive aluminum profile parts. When the multiple clamping plates 552 fit and clamp the automotive aluminum profile parts, the arc-shaped rubber strip 553 designed on one side of the clamping plate 552 effectively improves the protection of the side of the automotive aluminum profile parts. Since the automotive aluminum profile parts are not of a conventional shape, when the multiple clamping plates 552 drive the rubber strip 553 to fit on the side of the automotive aluminum profile parts, the multiple clamping plates 552 fit on the sides of the automotive aluminum profile parts at different positions. Therefore, a single clamping plate 552 is subjected to the resistance of the side of the automotive aluminum profile parts, and it shrinks to the inner cavity of the concave cover 551, thereby passing The two first connecting members 554 both drive the movable rod 555 to move synchronously, and the other ends of the two movable rods 555 drive the second connecting member 556 and the slide plate 557 to move in the opposite direction, and then the slide plate 557 synchronously compresses the spring rod 5514.

The limit block 558 is made of iron material.

[0034] When the clamping assembly 55 completes clamping of the automotive aluminum profile parts, by loosening the fixing bolts 5593 on the multiple fixing assemblies 559, it is convenient to stretch the two L-shaped plug plates 5591 on the outer side of the inner plate 5592, adjust the distance between the two L-shaped plug plates 5591, and adjust the length of the entire fixing assembly 559.
