Used fixing device based on cylindrical structure manufacturing

Abstract

The invention discloses a used fixing device based on cylindrical structure manufacturing. The used fixing device comprises a base, two vertical plates are arranged at the top of the base and positioned on two sides of an axis of the base, movable blocks are arranged in the vertical plates and cam vertically move in the vertical plates, adjusting rods are arranged on the movable blocks and horizontally connected with the movable blocks in a threaded manner, two supporting blocks are arranged at the top of the base and positioned between the two vertical plates and can move on the base towardsthe vertical plates, placing grooves are formed in the tops of the supporting blocks, strip-type grooves are formed in the vertical plates, two side walls of the vertical plates are communicated by the strip-type grooves, the movable blocks are positioned in the movable blocks, sliding grooves are formed in two sides of the inner walls of the strip-type grooves, and second sliders matched with the sliding grooves are arranged on two sides of the movable blocks and positioned in the sliding grooves and can move in the sliding grooves.

Description

technical field [0001] The invention relates to the field of machining of mechanical parts, in particular to a fixing device used in the manufacture based on a cylindrical structure. Background technique [0002] A fixture, also known as a jig, is a device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position and accept construction or testing. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. When drilling the side wall of a part with a long axis such as a column, generally the two ends of the part are clamped, and then the side wall is drilled. However, this method makes the part between the clamps at both ends in a suspended state, and when drilling, the tool will generate greater stress on the part from top to bottom,...

AI Technical Summary

Problems solved by technology

However, this method makes the part between the clamps at both ends in a suspended state, and when drilling, the tool will generate greater stress on the part from top to bottom, thus affecting the quality of the part, especially the part. On the side wall of the part, and if the clamping force on both ends of the part is loosened by the fixture, the suspended part will tilt or fall off, resulting in the scrapping of the processed part. At the same time, when the side wall of the part is drilled, the iron chips generated On the surface of the part, it affects the normal processing of the part
