A bolt processing surface treatment device

Abstract

The invention discloses a bolt machining surface treatment device, and relates to the technical field of bolt machining equipment. The bolt machining surface treatment device comprises an operating platform, a pressing mechanism and a polishing device. The pressing mechanism comprises an air cylinder, a sliding base, a first fastening plate and a second fastening plate, the portion, at the right end of the air cylinder, of the operating platform is provided with a sliding groove, the sliding base is installed in the sliding groove in a sliding mode, the right end face of the first fastening plate is provided with a first clamping groove, the left end face of the first fastening plate is connected with the telescopic end of the air cylinder in a fastened mode, the second fastening plate is installed on the operating platform in a fastened mode and located at the tail end of the sliding groove, and the left end face of the second fastening plate is provided with a second clamping groove. The polishing device is located at the right end of the pressing mechanism and comprises a rotating motor and a polishing mechanism, and the polishing mechanism comprises a disc, supporting rods and brushes. The bolt machining surface treatment device is simple in structure; when used for polishing the screw parts of large bolts, the bolt machining surface treatment device improves the bolt machining quality, reduces the labor intensity of workers, improves the polishing efficiency and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of bolt processing equipment, in particular to a bolt processing surface treatment device. Background technique: [0002] Bolts are commonly used fasteners in daily life. There are hexagonal or cross-shaped grooves on the bolt heads. Appropriate tools can be inserted into these grooves to tighten or loosen the bolts, so as to fasten the mechanical parts. the goal of. [0003] During the manufacturing process of the bolt, it is necessary to process the external thread on the cylinder on the bolt. During the process of tapping the cylinder, because the bolt is a metal part, burrs or wires will be generated on the surface, resulting in thread distortion. The surface is not smooth enough.

Problems solved by technology

[0003] During the manufacturing process of the bolt, it is necessary to process the external thread on the cylinder on the bolt. During the process of tapping the cylinder, because the bolt is a metal part, burrs or wires will be generated on the surface, resulting in thread distortion. The surface is not smooth enough. In order to ensure the processing quality of the bolt, the screw part needs to be polished. The usual way is to make the worker use sandpaper to wipe the surface of the screw to eliminate burrs or metal wires on the surface, but this method is not suitable for some larger bolts. However, it is obviously impossible to improve the processing efficiency, and the bolt needs to be turned during grinding, which is very inconvenient for grinding, reduces the processing efficiency, and increases the production cost.
