Description

Technical Field

[0001] This invention relates to the field of vacuum pump manufacturing equipment, and more particularly to a vacuum pump housing grinding device. Background Technology

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container and create a vacuum. In simpler terms, a vacuum pump is a device that uses various methods to improve, generate, and maintain a vacuum in a closed space. After processing, the surface of a water pump casing will have burrs, requiring deburring. Deburring removes the burrs or flash formed at the intersections of the parts' surfaces.

[0003] Patent application number CN202122574624.2 discloses a deburring device for pump production, including a base. The base has an internal groove, and a lead screw is rotatably connected to the inner wall of the groove. Two sliding blocks are threaded onto the surface of the lead screw. A connecting rod is fixedly connected to the upper end of each sliding block. A limiting groove adapted to the connecting rod is formed on the upper surface of the base. A grinding table is fixedly connected to the upper end of the connecting rod, and a circular hole is formed at the lower end of the grinding table. A servo motor is fixedly connected to the right side of the base, and the output shaft of the servo motor is fixedly connected to the right end of the lead screw. A drive motor is fixedly connected to the left side of the base. A first limiting rod is rotatably connected to the upper surface of the base, and a limiting plate is threaded onto the inner wall of the first limiting rod. A second limiting rod is fixedly connected to the upper surface of the base, and the surface of the second limiting rod is slidably connected to the inner wall of the limiting plate. A through groove is formed on the surface of the limiting plate, and an adjusting motor is fixedly connected to the inner wall of the through groove. A grinding head is fixedly connected to the output shaft of the adjusting motor. In use, the motor drives the grinding head to rotate, which in turn drives the first limiting rod to rotate. This causes the limiting plate to move the grinding head downwards, which can grind the burrs on the vacuum pump. However, since the pump body surface is not a smooth curved surface and has multiple protrusions, the grinding head cannot grind the position where the pump body meets the protrusions when it is lowered to grind the pump body.

[0004] This invention was developed to address the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vacuum pump housing polishing device.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a vacuum pump housing grinding device, comprising a base plate, on which a screw and a slide rod are disposed. The screw is driven to rotate by a positioning motor. A slide table is also disposed above the base plate, through which the screw passes and is threadedly connected to the slide table. The slide rod passes through the slide table and is slidably connected to the slide table. A rotating shaft is also disposed on the slide table, driven to rotate by a rotary motor. Multiple fixing devices are also disposed on the rotating shaft. Each fixing device includes a positioning plate, with positioning rods rotatably connected to both ends of the positioning plate. The ends of the positioning rods are disposed on the rotating shaft and rotatably connected to the rotating shaft. A positioning shaft is also fixed to one of the positioning rods of the fixing device. A lead screw is disposed on the rotating shaft, driven to rotate by a fixing motor. A push plate is disposed on the lead screw, through which the lead screw passes and is threadedly connected to the push plate. The push plate is connected to the positioning shaft, and positioning pins are fixed at the corresponding positions. The positioning pins are connected to the positioning shaft at the corresponding positions through push rods. A support plate is also provided above the base plate. Multiple lifting cylinders are fixed on the base plate. The piston rods of the lifting cylinders are fixed to the support plate. A support block is fixed above the support plate. A fixing plate is provided above the support block. A support plate is fixed on the top of the fixing plate. A grinding motor is also fixed on the support plate. A friction roller is fixed at the output end of the grinding motor. A positioning roller is also provided on the support plate below the friction roller. A grinding belt is also provided above the base plate. The grinding belt passes around the friction roller and the top of the support plate. Multiple support rods are also fixed on the support block. The ends of the support rods are set on the fixing plate and slidably connected to the fixing plate. Multiple springs are also fixed between the fixing plate and the support block. The pump body to be ground is fixed on the rotating shaft. After the rotating shaft is inserted into the pump body, the fixed motor is started, driving the lead screw to rotate. When the fixed motor rotates, the push plate moves in the direction of the lead screw, and the push rod pushes the positioning rod to rotate. The positioning plates move away from the rotating shaft. After all the positioning plates have moved away from the rotating shaft and are in contact with the inner wall of the pump body, the pump body is fixed on the rotating shaft. The positioning motor drives the screw to rotate, and the slide moves in the direction of the screw. After the pump body moves above the grinding belt, it stops. The lifting cylinder is started, and the piston rod on the lifting cylinder extends, causing the grinding belt to rise. The grinding belt at the top of the support plate contacts the surface of the pump body, and is then driven by the grinding motor. The moving friction roller rotates, and the grinding belt passes between the friction roller and the positioning roller. The friction roller drives the grinding belt to rotate. After the grinding belt contacts the pump body surface, it grinds the pump body surface. The rotating motor drives the rotating shaft to rotate, and the rotating shaft drives the pump body to rotate. After the pump body is ground once, the positioning motor drives the screw to rotate a certain number of times, and the pump body moves a certain distance again. The grinding belt grinds the pump body again. This cycle can grind the surface of the pump body. The grinding belt is pushed to contact the pump body by the support plate. The grinding belt can be inserted into the intersection of the pump body and the protrusions on the pump body for grinding, which can achieve all-round grinding of the pump body surface.

[0008] Preferably, a driven wheel is fixed on the rotating shaft, and a driving wheel is fixed at the output end of the rotary motor. The driving wheel is connected to the driven wheel via a synchronous belt.

[0009] Preferably, the support plate has multiple balls on its top and both sides. The grinding belt contacts the balls, and the balls roll on the surface of the support plate, which can prevent the grinding belt from wearing out.

[0010] Preferably, a limiting shaft is fixed on the fixing plates on both sides of the support plate, and a limiting roller is provided on the limiting shaft for rolling connection with the limiting shaft. The grinding belt passes between the limiting roller and the support plate.

[0011] Compared with existing technologies, the present invention has the following advantages:

[0012] This device can grind the surface of the pump body, and push the grinding belt to contact the pump body through the support plate. The grinding belt can be inserted into the junction of the pump body and the protrusion on the pump body for grinding, which can achieve all-round grinding of the pump body surface.
