An automatic sandblasting machine

Abstract

The invention discloses an automatic sand-blasting machine. A motor drives a rotating table to rotate in a stepping manner through a rotation divider; an angle displacement output shaft of the rotation divider is in transmission connection with the rotating shaft of the rotating table; a feeding chamber, a discharge chamber, a left partitioning chamber, a right partitioning chamber and various working stations occupy equal spaces respectively; the stepping angle of the angle displacement output shaft is identical to corresponding angles of the various adjacent working stations relative to the center of a cylindrical shell; the automatic sand-blasting machine further comprises a start button, a stop button, a grating sensor and a rotating table displacement sensor which are connected with a PLC digital quantity input end; a motor and a nozzle compressed air control valve are controlled through PLC digital quantity output signals; the grating sensor is used for detecting whether a human body exist before a feeding hole or a discharge hole. The automatic sand-blasting machine has the characteristics of high automation degree, high working efficiency, safe operation, energy conservation, consumption reduction and the like.

Description

technical field [0001] The invention relates to an automatic sandblasting machine. Background technique [0002] During the production process of castings, there are often impurities such as scale and attachments on the surface that are difficult to clean. The rotary sandblasting machine completes the cleaning of the casting surface, and sprays the high-speed steel shot to the casting surface for cleaning. Therefore, the cleaning room body needs to be a closed environment, and the safety protection door is even more important. At present, when the rotary sandblasting machine is turned on, all the nozzles of the working positions start to work, and when the machine is stopped, all the nozzles of the working positions stop working, and the nozzles of the working positions without castings to be cleaned work blindly, resulting in waste of energy and materials; at the same time, the sandblasting machine is working When it is used, it is easy to spray high-speed steel shots from...
