Rolling wheel fixing clamp in sand-blasting machine

Abstract

The invention discloses a rolling wheel fixing clamp in a sand-blasting machine. The rolling wheel fixing clamp comprises a fixed seat. A bottom plate is fixed to the lower end face of the fixed seat.A bearing pedestal is fixed to the upper end of the fixed seat. An edge-on three-claw chuck is arranged on the front side of the bearing pedestal. A main shaft is fixed to the center of the bottom face of the three-claw chuck and is hinged to a hinged seat. The main shaft stretches out of the hinged seat to form a branch shaft. A hand wheel is fixed to the rear end of the branch shaft. Lengthenedclamping rods are fixed to clamping claws of the three-claw chuck. A sand prevention cover is arranged outside the three-claw chuck in a sleeving manner and comprises a front face plate, a cover bodyand a rear face plate. The front face plate and the rear face plate are fixed to the front end face and the rear end face of the cover body correspondingly. The rear face plate is fixed to the rear end face of the fixed seat. Multiple supporting supports are fixed to the two side walls of the fixed seat. The supporting supports are fixed to the inner side wall of the cover body. A rotating disc is arranged on the front face plate in an abutting manner. According to the rolling wheel fixing clamp, a jig which achieves clamping and is fixed is modified into the clamp capable of rotating and achieving inner and outer wall clamping, sand blasting to various faces in the sand blasting process is facilitated, and convenience is brought to sand blasting work.

Description

Technical field: [0001] The invention relates to the technical field of roller processing equipment, in particular to a roller fixing fixture in a sandblasting machine. Background technique: [0002] Roller sandblasting machine is an important mechanical equipment in the processing of rollers. The sandblasting machine uses compressed air as the power to form a high-speed jet beam to spray the spray material at high speed on the surface of the workpiece to be treated, so that the outer surface of the workpiece surface looks or When the shape changes, due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved, thus improving the fatigue resistance of the workpiece and increasing the The adhesion between it and the coating prolongs the durability of the coating film, and is a...

AI Technical Summary

Problems solved by technology

In the process of processing the roller, it needs to be sand blasted, and some roller sandblasting needs to treat all surfaces of the roller, but the existing roller clamping fixture is clamped and fixed on both sides of the roller to realize The rollers are fixed, and the sandblasting operation is inconvenient during the actual sandblasting process
