A two-degree-of-freedom movable clamping platform for hole grinding

Abstract

The invention relates to a two-degree-of-freedom movable clamping platform for hold grinding. The clamping platform comprises an L-shaped rack and a rectangular hollowed-out frame, wherein the L-shaped rack comprises a vertical plate and a movable plate, the vertical plate is perpendicularly fixed above the back side of the movable plate, a U-shaped cutter groove is formed in the middle-upper part of the back side of the vertical plate, the L-shaped rack is located above the middle of the rectangular hollowed-out frame, front and back sides of the movable plate are connected with the rectangular hollowed-out frame through transverse movable devices, left and right sides of the movable plate are connected with the rectangular hollowed-out frame through longitudinal movable devices, a positioning and cooling device is installed in the middle of the left side of the vertical plate, and a pressing device is installed in the middle of the right side of the vertical plate. The clamping platform has the advantages of reasonable structural design, high automation degree, convenience in operation and the like and is used for accurately positioning and clamping braking hydraulic cylinders, the cooling performance of hole grinding is improved, and the clamping platform can be used for performing hole grinding on two piston cylinders of double-pipeline braking hydraulic cylinders by the aid of the transverse and longitudinal movable devices, is convenient to adjust and can guarantee the hole grinding accuracy.

Description

technical field [0001] The invention relates to auxiliary equipment for hole grinding of brake hydraulic cylinders, in particular to a two-degree-of-freedom movable clamping platform for hole grinding. Background technique [0002] The general production process of the brake hydraulic cylinder block is: casting blank - milling plane - drilling - reaming - grinding - finished product. In the process of grinding the hole of the brake hydraulic cylinder, some brake hydraulic cylinders have two piston cylinders that need to grind holes, and the operation of changing the position of the brake hydraulic cylinder is manual by workers, and the degree of automation It is relatively low, and the operation is cumbersome. Sometimes, due to the inaccurate clamping and positioning after the transformation, the positions of the two piston cylinders after the grinding holes do not correspond, and grinding is required. In serious cases, the parts may be scrapped; the traditional brake hydrau...

Problems solved by technology

In the process of grinding the hole of the brake hydraulic cylinder, some brake hydraulic cylinders have two piston cylinders that need to grind holes, and the operation of changing the position of the brake hydraulic cylinder is manual by workers, and the degree of automation It is relatively low, and the operation is cumbersome. Sometimes, due to the inaccurate clamping and positioning after the transformation, the positions of the two piston cylinders after the grinding holes do not correspond, and grinding is required. In serious cases, the parts may be scrapped; the traditional brake hydraulic cylinder is mostly Thick and large parts, while the general grinding machine only cools the outside of the grinding part through coolant, resulting in heat collection inside the brake hydraulic cylinder and poor cooling performance. Once overheated, the material of the cylinder will be burned, and the cylinder The change of the mechanical properties of the body will also affect the accuracy of the grinding hole
