Box body type workpiece shot blasting cleaning device for upper mobile material conveying

Abstract

The invention discloses a box body type workpiece shot blasting cleaning device for upper mobile material conveying. The box body type workpiece shot blasting cleaning device comprises a shot blasting chamber, shot blasters mounted on the shot blasting chamber, a shot and sand circulating system matched with the shot blasters and a shot and sand separator, wherein a workpiece inlet is formed in one side surface of the shot blasting chamber; the shot blasting cleaning device further comprises material conveying roller ways arranged at one side of the workpiece inlet of the shot blasting chamber and material feeding manipulators; each material feeding manipulator comprises a stander; a rail and a power trolley matched with the rail are arranged on the top of the stander; the direction of the rail is perpendicular to the material conveying roller ways; a lifting hook is perpendicularly mounted on the power trolley; the lower end of the lifting hook is opposite to the workpiece inlet of the shot blasting chamber; a rotary workbench is arranged in the shot blasting chamber; a clamp is arranged on the rotary workbench. The box body type workpiece shot blasting cleaning device is used for achieving multi-orientation and high-efficiency shot blasting treatment of a box body; the possibility of cleaning dead corners is reduced to minimum; the box body type workpiece shot blasting cleaning device is low in overall manufacturing cost, easy to operate, convenient to maintain and good in use effect.

Description

technical field [0001] The invention relates to the technical field of shot blasting, in particular to an upper-mounted mobile feeding box-like workpiece shot blasting device. Background technique [0002] Nowadays, when the surface of the engine case is cleaned and treated in industrial production, shot blasting technology is mostly used for process treatment. The principle is to put the workpiece in a closed container and use a shot blaster to accelerate the projectile. The projectile directly collides with the surface of the workpiece, and the remaining impurities on the surface of the workpiece are cleaned by collision, so as to achieve the purpose of cleaning the surface of the workpiece. Therefore, the workpiece after shot blasting not only increases the surface finish, but also improves the stress state of the workpiece surface, making it in a state of compressive stress, and improving the durability and fatigue strength of the workpiece. [0003] But the shot blasti...

Problems solved by technology

[0003] But the shot blasting machine that current industry is used mainly has the defective of two aspects when carrying out shot blasting cleaning to engine casing: the one, when carrying out shot blasting cleaning to engine casing, need too much manpower labor, can't realize automation, cost Higher, low mechanical efficiency; second, the position of the workpiece in the shot blasting chamber can only be adjusted relatively, and the relative direction of the projectile and the workpiece cannot be adjusted in all directions, so the projectile thrown by the shot blaster can only hit a part of the workpiece The surface, the part that the projectile cannot hit will be treated and cleaned incompletely
