Description

Technical Field

[0001] The invention relates to the field of vacuum pump production devices, and in particular to a vacuum pump housing polishing device. Background Art

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space. After the pump housing is processed, there will be burrs on its surface, which needs to be removed. Deburring is to remove the thorns or flash formed at the intersection of the part surface and the surface.

[0003] Patent application number: CN202122574624.2 discloses a deburring device for pump production, including a base, a groove is opened inside the base, the inner wall of the groove is rotatably connected to a lead screw, the surface of the lead screw is threadedly connected to two sliding blocks, the upper end of the sliding block is fixedly connected to a connecting rod, the upper surface of the base is opened with a limiting groove adapted to the connecting rod, the upper end of the connecting rod is fixedly connected to a grinding table, the lower end of the grinding table is opened with a circular hole, the right side of the base is fixedly connected to a servo motor, the output shaft of the servo motor is fixedly connected to the right end of the lead screw, the left side of the base is fixedly connected to a driving motor, the upper surface of the base is rotatably connected to a first limiting rod, the inner wall of the first limiting rod is threadedly connected to a limiting plate, the upper surface of the base is fixedly connected to a second limiting rod, the surface of the second limiting rod is slidably connected to the inner wall of the limiting plate, the surface of the limiting plate is opened with a through groove, the inner wall of the through groove is fixedly connected to an adjusting motor, and the output shaft of the adjusting motor is fixedly connected to a grinding head. When in use, the motor is adjusted to drive the grinding head to rotate, and the driving motor drives the first limiting rod to rotate, so that the limiting plate drives the grinding head to move downward, so that the burrs on the vacuum pump can be polished. However, since the surface of the pump body is not a smooth curved surface, and the surface of the pump body has multiple protrusions, the grinding head is lowered to polish the pump body, and the grinding head cannot polish to the position where the pump body and the protrusions intersect.
