Automobile aluminum alloy casting machining clamping jaw

Abstract

The invention discloses an automobile aluminum alloy casting machining clamping jaw. The automobile aluminum alloy casting machining clamping jaw is composed of a clamping jaw body, a main spring fixed bolt, a main spring, a moving bucket, an oil plug, an oil storage groove, a main oil path, branch oil paths, a pressing block, a limiting cover plate, a fixed bolt, limiting bolts, telescopic columns, a copper gasket, a locking bolt, a positioning pin and a stroke block; the clamping jaw is characterized in that the stroke block and the locking nut are arranged in a threaded hole in the middle of the pressing block, the copper pad is mounted on the pressing block through the fixed bolt, the pressing block is put into a groove of the clamping jaw body, the limiting cover plate is positioned on the clamping jaw body through the positioning pin, and fixing is achieved through the fixing bolt; the four telescopic columns are put into a thread through hole of the limiting cover plate and cylindrical holes in the upper step and the lower step of the pressing block, positions of two part holes correspond to each other, the telescopic columns are fixed through the limiting bolts, the movablebucket is loaded into the a step hole of the clamping jaw body, a main spring is put into the movable bucket, the spring is fixed to the bolt, and the axial positioning problem of a casting in the clamping process can be solved.

Description

technical field [0001] The invention belongs to the technical field of auto parts processing, and relates to a machining jaw of an auto aluminum alloy casting. Background technique [0002] Due to the emphasis on environmental protection and energy saving in various countries, automobile lightweight has become a research hotspot in the automotive industry at home and abroad. Automobile lightweight technology can effectively reduce fuel consumption, reduce emissions and improve safety. One of the main technical solutions for automobile lightweight is material lightweight. Since the density of aluminum is only 1 / 3 of that of steel, and aluminum alloy has relatively good comprehensive performance, many parts of the car are replaced by aluminum alloy. [0003] Casting is one of the main production methods of aluminum alloy auto parts. After the castings are produced, the next important process is machining. At present, there are many types of fixtures used in machining, and th...

Problems solved by technology

However, this clamping method belongs to radial clamping. During the tightening process, the end face of the aluminum alloy casting and the axial positioning block often do not contact. Especially in the actual production of the factory, manual axial positioning is required, which increases the labor force of the workers. workload

Even so, the occurrence of axial positioning problems cannot be eliminated, causing the aluminum alloy castings to be biased, affecting the quality of the product, and reducing the machining yield
