Electric polishing block base capable of changing grinding stroke

Abstract

The invention discloses an electric polishing block base capable of changing the grinding stroke. The electric polishing block base comprises a fixed seat and a reciprocating seat, a reciprocating cavity with an upward opening is formed in the fixed seat, and the reciprocating seat is slidably connected in the reciprocating cavity. A positioning mechanism and a power supporting mechanism are arranged in the fixed seat, the positioning mechanism is responsible for limiting movement of the reciprocating seat and resetting the reciprocating seat, the power supporting mechanism is used for providing power, and a transmission chain mechanism is mounted on the power supporting mechanism. According to the technical scheme, the electric polishing block base capable of being provided with a polishing block, driving the polishing block to move back and forth to grind a workpiece and freely adjusting the back-and-forth movement range within a range is provided. According to the electric polishing block base, the surface of the workpiece is ground through the polishing block mounted on the electric polishing block base, based on the performance characteristics of the polishing block, the polishing process of the electric polishing block base is quite gentle, and the surface of the workpiece is not prone to being damaged; and the electric polishing block base is simple in structure, relatively low in manufacturing cost, simple in principle and convenient to manufacture and maintain.

Description

technical field [0001] The invention relates to the related field of grinding, in particular to an electric polishing block base capable of changing the grinding stroke. Background technique [0002] Polishing block is a kind of grinding tool that is very common in the fields of model, literary play, handicraft, etc. Unlike sandpaper, polishing block will not make scratches, and can effectively improve the surface smoothness of the workpiece. At the same time, the polishing block on the market Most polishing blocks are made of soft materials, which are not easy to damage the surface of the workpiece; [0003] Most of the electric grinding tools or polishing tools on the market today are too rough and easy to damage the workpiece to be polished. It is tiring to hold the polishing block directly for grinding, and in the process of manual polishing, it is easy to be affected by the holding posture or angle. Not in place, etc. lead to uneven polishing, which affects the quality...

AI Technical Summary

Problems solved by technology

[0003] Most of the electric grinding tools or polishing tools on the market today are too rough and easy to damage the workpiece to be polished. It is tiring to hold the polishing block directly for grinding, and in the process of manual polishing, it is easy to be affected by the holding posture or angle. Not in place, etc. lead to uneven polishing, which affects the quality of polishing, and is easy to damage the polishing block quickly, affecting its service life;

[0004] When using a polishing block for grinding and polishing, the size of the workpiece to be polished may be different. It will be unnecessary and time-consuming to use a large stroke for small parts, and it will be inefficient to use a small stroke for large workpieces.
