Auto U-beam punching x-direction positioning device

Abstract

The invention discloses an X-direction positioning device for punching an automobile U-shaped beam, and belongs to the field of plate machining devices. The X-direction positioning device for punching the automobile U-shaped beam comprises a positioning frame mounted on a wing surface punching feeding device, wherein an air cylinder support is fixed on the side face of the positioning frame, an air cylinder is mounted on the lower side of the air cylinder support, a piston rod of the air cylinder stretches out from the lower end of the air cylinder and is connected with a connecting plate, the connecting plate is connected with a locating pin, the axis of the locating pin is arranged to be parallel to the axis of the air cylinder, and the positioning frame is provided with a hole which can allow the locating pin to stretch out of the positioning frame in an upward mode; an idler wheel support is arranged at the front end of the positioning frame, the idler wheel support is provided with an idler wheel, and the upper edge of the idler wheel is higher than the upper surface of the positioning frame. In the working process, the X-direction positioning device is mounted on the wing surface punching feeding device, the air cylinder can drive the locating pin to stretch out in an upward mode and to be inserted into a locating hole of the U-shaped beam, the position of wing surface punching is guaranteed, rearward face punching is guaranteed to have a fixed relative position, the X-direction position precision between wing surface punching and rearward face punching is greatly improved, and the X-direction positioning device for punching the automobile U-shaped beam is particularly suitable for machining the automobile U-shaped beam.

Description

technical field [0001] The invention relates to a positioning device for plate processing, in particular to a positioning device for punching U-shaped beams of automobiles. Background technique [0002] The U-shaped beam is an important part on the chassis of the car. The section of the U-shaped beam is U-shaped, and various holes are processed on the two wing surfaces of the U-shaped beam and the belly surface; The equipment for punching holes on the belly and airfoil usually punches the holes on the belly of the U-shaped beam on one piece of equipment, and then switches the U-shaped beam to another equipment, and then punches out the holes on the airfoil. When punching the belly face, the X-direction origin positioning of the U-shaped beam is determined by the photoelectric switch, and its positioning accuracy is affected by the feeding speed. The accuracy from the hole to the positioning edge is low, but the accuracy of the hole distance is not affected, so it does not af...

AI Technical Summary

Problems solved by technology

Its shortcoming is that the positioning of the photoelectric switch makes the X-direction accuracy of the ventral surface and the wing surface not high enough, which affects the assembly of the U-beam
