A multi-station assembly line connecting rod cracking groove wire cutting equipment

Abstract

The invention discloses a multi-station assembly line type connecting rod cracking trough line cutting equipment. Anti-collision fixture. When in use, the worker installs the connecting rod workpiece on the fixture panel at the loading station, and then releases the locking block, which withstands the connecting rod under the action of the locking spring; then the rotating mechanism drives the adjustable anti-collision fixture to turn to the processing Station, at this time, the left and right cylinders drive the U-shaped structure to move downward. If there is a collision with the connecting rod, the fixture panel will turn over, thereby reducing the collision damage. If there is no collision, the first motor will be used to adjust the grooving device During processing, the left and right sliders are driven by the second motor to adjust the relative or opposite movement of the left slider and the right slider, so as to process the cracking groove, and finally the rotating mechanism turns the processed connecting rod from the processing station back to the feeding station, and the loaded connecting rod to be processed is turned to the processing station for the next round of processing.

Description

technical field [0001] The invention relates to the technical field of electric discharge wire cutting, in particular to a multi-station assembly line type connecting rod cracking groove wire cutting equipment. Background technique [0002] Automobile connecting rod is an important component of automobile engine, which has an important influence on the performance of the engine. The connecting rod expansion technology is to apply a horizontal directional breaking force inside the big end hole of the connecting rod through the state, so that the crack in the cracking groove expands rapidly until it breaks, and the rod cover and the rod body are separated. The rod body and the rod cover are combined through the concave-convex fracture surface, which increases the accuracy and reliability compared with the traditional fracture surface. The connecting rod expansion process can reduce the process by up to 60%, reduce the investment by 25%-35%, and save energy by 40%. Processing...

AI Technical Summary

Problems solved by technology

[0005] Although the existing laser grooving has the characteristics of dry cutting and high efficiency, the equipment cost is high, and the imported laser head is expensive, even exceeding 50% of the overall equipment cost

Moreover, laser cutting is prone to produce high-hardness slag, which will cause tool chipping in the subsequent fine boring process

[0006] The connecting rod cracking groove device mentioned in the patent CN101125379A, because the "U" structure is designed at the bottom of the workbench, when clamping the connecting rod, it is necessary to pass the big end hole of the connecting rod through the supporting rod from above the supporting rod. It is easy for the connecting rod to collide with the "U" structure when clamping the connecting rod, which not only increases the difficulty of clamping the workpiece, but also may cause the deformation of the "U" structure and affect the processing accuracy of the equipment

And the efficiency of wire cutting and grooving equipment for a single station is lower than that of laser grooving equipment
