A machine for grinding the surface of a cast blank with a fixed tong body in a bench vise

Abstract

The invention relates to the technical field of bench vise grinding, in particular to a machine for grinding the surface of a casting blank of a fixed vise body of a bench vise, which includes a base, a fixing device and an actuator. The fixing device is installed inside the base, and the upper end of the base is An executive device is provided; the present invention can solve the following problems: the general casting blanks are mostly fixed by clamps, and the outer sides of the casting blanks are mostly arc-shaped structures, which will affect the fixing effect; the general casting blanks are large Part of it is to grind the internal through groove with a file, and then grind the anvil surface of the casting blank with a grinding wheel, so the grinding accuracy of the anvil surface of the casting blank cannot be guaranteed; The parts are fixed, and then the through groove of the casting blank is reciprocally polished by the elastic grinding sheet, and the anvil surface of the casting blank is polished by the grinding belt, so as to ensure the grinding accuracy of the anvil surface of the casting blank.

Description

technical field [0001] The invention relates to the technical field of bench vise grinding, in particular to a machine for grinding the surface of a casting blank of a bench vise fixed vise body. Background technique [0002] The bench vise is a universal fixture used to clamp the workpiece; the bench vise is composed of a fixed vise body, a movable vise body, a base, a guide nut, a lead screw, a jaw body, etc. The through groove for the sliding fit of the pliers body, fixing the welding anvil surface at the upper end of the pliers body (such as Figure 9 As shown), after the fixed pliers are cast, the through groove and the anvil surface of the casting blank of the fixed pliers need to be polished to ensure the smoothness of the through grooves in the fixed pliers, which is convenient to improve the movement of the movable pliers in the fixed pliers. The sliding stability and the smooth anvil surface are convenient for knocking, scribing and other processing of the workpiec...

AI Technical Summary

Problems solved by technology

[0003] However, at present, the following problems exist in the surface grinding of the cast blank of the pliers body: 1. The traditional cast blank is mostly placed on the existing fixture by manual auxiliary feeding, and then fixed by the fixture. The outer side of the cast blank is mostly curved, thus affecting the fastening effect

[0004] 2. Generally, when grinding the casting blank, most of the internal through grooves are polished with a file. Since the grinding range of the file is small, it takes a lot of time, and then the anvil of the casting blank is polished by a grinding wheel. If the distance between the casting blank and the grinding wheel changes, it is easy to cause grinding damage to the anvil surface of the casting blank, so that the grinding accuracy of the anvil surface of the casting blank cannot be guaranteed
