Sand blasting machine capable of automatically adjusting to achieve uniform sand blasting

Abstract

The invention relates to the technical field of sand blasting machines, and discloses a sand blasting machine capable of automatically adjusting to achieve uniform sand blasting. The sand blasting machine comprises a sand blasting chamber, a sand blasting gun is fixedly installed in the sand blasting chamber, an arc-shaped wall is arranged in the sand blasting gun, the bottom of the arc-shaped wall is connected with a muzzle, adjusting modules are installed on the inner walls of the left and right sides of the sand blasting chamber, a fixing block is installed below the sand blasting gun, thetop of the fixing block is connected with an air spring, and the top of the air spring is connected with a workbench. According to the sand blasting machine capable of automatically adjusting to achieve uniform sand blasting, pressure on the arc-shaped wall is transmitted to a first common spring through a first pressure rod, the first common spring is contracted or stretched through the pressure,a first gear, a first disc, a second disc, a sliding rod, a piston plate and the air spring are driven to move in a matched mode, and a workbench is made to move downwards or upwards; and therefore,the distance between the muzzle of the sand blasting gun and a workpiece on the workbench is increased or decreased, and the thickness of sand sprayed to the surface of the workpiece is uniform.

Description

technical field [0001] The invention relates to the technical field of sandblasting machines, in particular to a sandblasting machine which can be automatically adjusted to achieve uniform sandblasting. Background technique [0002] Sandblasting is a process for surface treatment of workpieces. Metal surface sandblasting is to spray the dry sand flow through the nozzle of the sandblasting machine on the metal surface at high speed under the action of purified compressed air, and use the strong impact of the sand flow on the metal surface. A surface treatment method that removes dirt, burrs, oxides, etc., and presents a surface with uniform roughness. [0003] The press-in dry sandblasting machine is powered by compressed air. During the use of the sandblasting machine, the air from the air compressor has a pressure difference, which causes the air pressure of the spray gun to be unstable. When the air pressure is high, there will be more sand inhaled and ejected. The opposi...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a sandblasting machine that can be automatically adjusted to achieve uniform sandblasting, which has the advantage of automatically adjusting the thickness of the sandblasting when the pressure of the air compressor is unstable, and solves the problem of sandblasting. The problem of uneven sandblasting thickness when the air pressure of the air compressor is unstable
