Automatic loading-unloading device for lifting-hook type shot blasting machine workpieces

Abstract

The invention relates to an automatic loading-unloading device for lifting-hook type shot blasting machine workpieces. The problems that rotation of a lifting hook of an existing lifting-hook type shot blasting machine is not reliable, the hooking direction position of the lifting hook is not determined, and automatic control of workpiece loading and unloading cannot be achieved are mainly solved. The automatic loading-unloading device for the lifting-hook type shot blasting machine workpieces is characterized in that a lifting hook is divided into an inner lifting hook body (3) and an outer lifting hook body (4), a first air cylinder (5) and a support (6) are fixed above a shot blasting room (1), and a second air cylinder (7) is fixed above the support (6); and a piston rod of the second air cylinder (7) is connected with a slippage trolley (15), a piston rod of a third air cylinder (16) is connected with a lifting sliding plate (17), and a piston rod of a fourth air cylinder (18) is connected with the outer lifting hook body (4). According to the automatic loading-unloading device for the lifting-hook type shot blasting machine workpieces, the structure with the inner lifting hook body and the outer lifting hook body being connected with each other is adopted, a driving gear on a reduction box and a driven gear on the inner lifting hook body cannot be separated, rotation of the lifting hook is reliable, the hooking direction positions of the inner lifting hook body and the outer lifting hook body are accurate, automatic workpiece loading and unloading can be achieved, and working efficiency is improved.

Description

technical field [0001] The invention relates to a shot blasting machine, in particular to an automatic workpiece loading and unloading device for a hook type shot blasting machine. Background technique [0002] The shot blasting machine is a device that uses high-speed projectiles thrown by the shot blasting machine to clean or strengthen the surface of the workpiece. The hook type shot blasting machine is one type of shot blasting machine. The existing hook type shot blasting machine is provided with a hook above the shot blasting chamber, and the hook enters or moves out of the shot blasting chamber through the gap at the top of the shot blasting chamber. For some small workpieces, the small workpiece is usually hung on the hanger, and then the hanger is hoisted by the hook into the shot blasting room for shot blasting. In order to reduce the dead angle, the outer surface of the workpiece can be hit by shot blasting. Generally, a reducer is used to drive the hook to rotat...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of unreliable rotation of the hook of the existing hook-type shot blasting machine, uncertain hook position and automatic control of workpiece loading and unloading, the present invention provides an automatic loading and unloading device for hook-type shot blasting machine workpieces , the automatic loading and unloading device of the hook-type shot blasting machine adopts the structure that two sets of hooks are connected to each other. The driving gear on the reducer and the passive gear on the inner hook will not be separated. The hook position is accurate, which can realize automatic loading and unloading of workpieces and improve work efficiency
