Technical Field

The invention relates to the field of shot blasting machines, in particular to a compressing device of a shot blasting machine.

Background

The shot blasting machine is a device for cleaning or strengthening the surface of a casting by using high-speed shots thrown by the shot blasting machine, and the shot blasting machine can perform sand falling, core removal and cleaning on the casting. The shot blasting machine can also be used for removing burrs, diaphragms and rust on the surface of a workpiece.

In order to fully clean the surface of a workpiece, when the surface is treated, one end of the workpiece is fixed by a clamping mechanism in the shot blasting machine, the other end of the workpiece is fixed by a pressing mechanism in the shot blasting machine, the clamping mechanism rotates the workpiece, and a pressing unit of the pressing mechanism, which is used for pressing the workpiece, rotates along with the workpiece, so that the surface of the workpiece is fully cleaned. However, when the existing pressing unit presses the workpiece, the pressing force cannot be adjusted, so that the workpiece is easily extruded and deformed, and the product is damaged.

Disclosure of Invention

In view of the above, the invention provides a compressing device of a shot blasting machine, which solves the problem that the compressing force degree of the compressing device of the existing shot blasting machine is not adjustable, and a workpiece is easy to deform.

Therefore, the invention provides a compressing device of a shot blasting machine, which comprises a guide rail, a movable compressing device and a driving cylinder, wherein the movable compressing device comprises a mounting bottom plate, a mounting frame and a compressing unit, the mounting bottom plate is connected to the guide rail in a sliding mode, the mounting frame is perpendicular to the mounting bottom plate, the compressing unit comprises a mounting seat and a compressing disc, the mounting seat is fixedly mounted on a flange of the mounting frame, the compressing disc is rotatably mounted in the mounting seat and comprises a rotating shaft and an end plate, a spring is sleeved on the rotating shaft, the compressing disc is elastically connected in the mounting seat, the end part of a workpiece is abutted to the end plate, and the end part of a piston rod of the driving cylinder is.

Further, a pressure sensor is arranged in the flange, and the pressure sensor and the rotating shaft are coaxially arranged.

Furthermore, a shaft sleeve is sleeved on the rotating shaft, a bearing is sleeved on the shaft sleeve, and the pressing disc is rotatably installed in the installation seat through the shaft sleeve.

Further, an annular groove is arranged on the end plate.

Further, a first blocking cover located above the mounting seat is arranged on the mounting frame.

Furthermore, a second baffle cover positioned above the driving cylinder is also arranged on the mounting frame.

Furthermore, the guide rail comprises two guide rail units which are symmetrically arranged, guide wheels which are symmetrically arranged are arranged on two sides of the installation bottom plate, and the guide wheels run on the guide rail units.

Furthermore, the mounting bottom plate is in an inverted 'V' -shaped structure.

According to the compressing device of the shot blasting machine, when a workpiece is subjected to surface treatment by the shot blasting machine, one end of the workpiece is clamped by the clamping mechanism, the driving cylinder drives the movable compressing device to slide on the guide rail, and the compressing unit of the movable compressing device compresses the other end of the workpiece. The pressing disc of the pressing unit is elastically connected in the mounting seat through the spring sleeved on the rotating shaft, so that the pressing disc cannot extrude and deform the workpiece under the condition of ensuring the pressing of the workpiece. The pressing plate is rotatably installed in the installation seat through the shaft sleeve, the pressing plate cannot be interfered by dust when rotating like a whole rotating pressing unit in the prior art, and two bearings sleeved on the shaft sleeve further guarantee that the pressing plate rotates smoothly.

The compressing device of the shot blasting machine provided by the invention can not extrude and deform the workpiece under the condition of ensuring the workpiece to be compressed.
