Plate shearing machine eccentric sleeve polishing device

Abstract

The invention discloses a plate shearing machine eccentric sleeve polishing device in the field of plate shearing machine eccentric sleeve machining. The device comprises a base, a first square grooveand a third square groove are formed in the upper end of the base, a first guide groove is formed in the side end of the first square groove, a first threaded block is slidably arranged in the firstguide groove, a first supporting plate is fixedly connected to the upper end of the first threaded block, a hydraulic cylinder is fixedly connected to the front end of the first supporting plate, a hydraulic rod is sleeved with the hydraulic cylinder, and a polishing block is fixedly connected to the front end face of the hydraulic rod. The first threaded block is in threaded connection with a lead screw, a first bevel gear is fixedly connected to the side end of the lead screw and meshes with a second bevel gear, the front end of the second bevel gear is fixedly connected with a first rotating shaft, and the front end of the first rotating shaft is fixedly connected with a first disc. The device is simple in structure and low in manufacturing cost, and only through simple operation, the size of an end face can be changed and the distance between two clamps can be adjusted.

Description

technical field [0001] The invention relates to the field of processing eccentric sleeves of shearing machines, in particular to a polishing device for eccentric sleeves of shearing machines. Background technique [0002] The shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to the other blade to cut the plate. It uses the moving upper blade and the fixed lower blade to apply shearing force to metal sheets of various thicknesses with a reasonable blade gap, so that the sheets are broken and separated according to the required size. The shearing machine is a kind of forging machinery, and its main function is the metal processing industry. The shearing machine is a kind of shearing equipment widely used in machining, which can cut steel plate materials of various thicknesses. Commonly used shears are divided into three types: flat shears, rolling shears and vibration shears. The products are widely used in aviation, light indu...

Problems solved by technology

[0003] However, the traditional eccentric sleeve polishing device cannot adjust the size of the end face of the fixture according to the size of the end face of the eccentric sleeve when grinding the outer surface of the eccentric sleeve. When processing eccentric sleeves of different sizes, different fixtures must be replaced. It is not only time-consuming and laborious, but also increases the cost of use and wastes resources; when the traditional eccentric sleeve polishing device adjusts the processing length, it relies on moving the tailstock to adjust the distance between the fixtures, and it needs to move the tailstock. Loosen the set stud and then hold the eccentric sleeve for comparison, and try it while moving, which increases the difficulty of length adjustment
