Workpiece cleaning system

Abstract

The invention discloses a workpiece cleaning system. The workpiece cleaning system comprises a cleaning bin, a supporting table, a fetching mechanism for clamping to-be-cleaned workpieces, and a sand-blasting gun. The fetching mechanism comprises a mounting base, a first drive piece, at least two clamping claws and a second drive piece connected with the mounting base through a rotating shaft, thefirst drive piece is connected with the clamping claws and used for driving the clamping claws to clamp or release the workpieces, and the second drive piece drives the mounting base to rotate. The sand-blasting gun comprises a body, a pipe opening in the rear end of the body is connected with a liquid inlet pipe, and the liquid inlet pipe is connected with a two-cylinder pressure pump; the bodyis provided with a control piece; and the front end of the body is connected with a nozzle, a fluid inlet of the nozzle is connected with a pipe opening in the front end of the body, a sand inlet of the nozzle is connected with a sand inlet pipe, and the sand inlet pipe is connected with a sand source. The two-cylinder pressure pump comprises a first plunger pump, a second plunger pump and a drivedevice for driving the first plunger pump and the second plunger pump to output high-pressure liquid alternately. The workpiece cleaning system is low in manual cost, high in safety performance, highin jet pressure, thorough in cleaning, free of cleaning dead corners and high in cleaning efficiency.

Description

technical field [0001] The invention belongs to the field of workpiece processing, in particular to a workpiece cleaning system. Background technique [0002] After the workpiece is processed, it needs to be cleaned. At present, the workpiece is usually cleaned by high-pressure liquid jetting on the market. Generally, the workpiece is placed in the cleaning chamber manually and cleaned uniformly. If the cleaning process needs to change the position of the workpiece, it needs to be stopped. Jetting of high-pressure liquid, and then turning over the workpiece by hand to continue cleaning, the process is cumbersome, the labor cost is high, the cleaning efficiency is low, there are cleaning dead angles, and the cleaning effect is not good. [0003] Sandblasting guns are widely used in cleaning processes such as rust removal, descaling, and deburring of workpieces. Sandblasting is to use high-pressure or high-speed airflow to mix sand material and airflow in the sandblasting devi...
