Radian-adjustable arc grinding gun

Abstract

The invention provides a radian-adjustable arc grinding gun, and relates to the field of grinding equipment. The arc grinding gun comprises a gun body. A power assembly is arranged in the gun body, and the output end of the power assembly is connected with a grinding rod. The tail end of the grinding rod is connected with an adjustable arc grinding head. The adjustable arc grinding head comprises a shell, an air inlet interface and a valve. The upper end of the shell is connected to the grinding rod. A plurality of groups of linearly arranged air cavities and piston cavities are formed in the shell. Piston heads are connected in the piston cavities in a sliding manner, piston rods are connected to the outer side ends of the piston heads, springs are accommodated between the interiors of the piston cavities and the piston heads, the heads of the piston rods are connected with top blocks, and the outer sides of the top blocks are connected with flexible sand plates. Air inlets and air outlets are formed in the side walls of each air cavities, the air inlets are connected with air inlet connectors, the air outlets are connected with valves, and the piston heads are locked in the piston cavities through the valves. According to the radian-adjustable arc grinding gun, the arc shapes of the surfaces of the flexible sand plates are changed by adjusting and fixing the length of the piston rods, the arc grinding gun adapts to arc surfaces with different radians, the applicability is higher, and the grinding efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to an arc grinding gun with adjustable arc. Background technique [0002] The so-called special-shaped parts refer to workpieces with non-rotating structure, non-rotating body and asymmetric shape, collectively referred to as special-shaped parts. In short, it is an irregularly shaped piece. The polishing and deburring of special-shaped parts has always been the main factor affecting the production efficiency of special-shaped parts. Special-shaped parts often have more curved inner and outer facades. For grinding such curved inner and outer facades, traditional grinding tools should Due to the limitations of the grinding head, the grinding angle cannot be changed according to the radian of the inner and outer facades, which greatly reduces the grinding efficiency and affects the grinding accuracy.

The polishing and deburring of special-shaped parts has always been the main factor affecting the production efficiency of special-shaped parts. Special-shaped parts often have more curved inner and outer facades. For grinding such curved inner and outer facades, traditional grinding tools should Due to the limitations of the grinding head, the grinding angle cannot be changed according to the radian of the inner and outer facades, which greatly reduces the grinding efficiency and affects the grinding accuracy

[0005]The above existing technologies all have problems such as poor applicability, low precision, complex structure, etc., and are not suitable for special-shaped workpieces with multi-curved inner and outer facades
