Precision casting part surface sand blasting polishing device

Abstract

The invention discloses a precision casting part surface sand blasting polishing device, which comprises a sand blasting box with an opening formed in the upper end; two sliding plates are arranged inthe sand blasting box; the sliding plates are slidably connected to the inner side wall of the sand blasting box; threaded rods are arranged between the two sliding plates and the inner side wall ofthe sand blasting box; the threaded rods are provided with two sections of threads opposite in rotating direction; the two sections of threads are connected with threaded sleeves in a threaded and sleeved mode; the ends, close to the sliding plates, of the threaded sleeves are rotatably connected with pushing rods; the pushing rods are rotatably connected to the side walls of the sliding plates; and a driving box is fixedly connected to the outer side wall of the sand blasting box, and a driving mechanism is arranged in the driving box. By arranging the driving mechanism, the clamping precision can be improved, and subsequent machining treatment is facilitated; and by arranging a rotating disc, a casting part can be driven to rotate at the same time, and complete and efficient sand blasting and polishing treatment is conducted on the surface of the casting part in cooperation with continuous sand blasting and reciprocating motion of a spray head.

Description

technical field [0001] The invention relates to the related technical field of casting processing equipment, in particular to a precision casting surface sandblasting and polishing device. Background technique [0002] The process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the spray material to the surface of the workpiece to be processed at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes, which is often used in the polishing of castings. [0003] However, the general sandblasting treatment is to manually hold the casting through gloves, and then manually use the spray gun to perform sandblasting and polishing on the surface of the casting. However, due to the poor stability of manual holding, when performing sandblasting, It is very easy for the sandblasting and polishing degree of each position to ...
