Description

Technical Field

[0001] The utility model relates to the field of grinding equipment, in particular to a grinding device for processing a balancing disc. Background Art

[0002] The balancing disc is a disc placed behind the last-stage impeller (high-pressure end) of a centrifugal compressor. The axial thrust generated by the pressure difference of the gas on both sides of the disc is used to partially offset the axial force of the rotor. In order to reduce the roughness of its surface, it is often necessary to grind its surface. A disc side grinding device is disclosed in the Chinese utility model patent with the announcement number CN218837127U. The device uses a lifting component to drive the rotating component and the grinding wheel to move up and down. The rotating component can drive the grinding wheel to rotate. The grinding wheel can grind the side of the disc-shaped metal workpiece. During the grinding process, the dust collection component can absorb the debris generated by the grinding into the inside through the connecting groove. In the above structure, the grinding roller is arranged below the second connecting gear, and the second connecting gear is connected to the drive motor through a connecting rod. The grinding roller can make a circular motion, but the radius of its motion is fixed, that is, the device can only grind a circular plate of one diameter, and its scope of application is small. For this reason, we designed a grinding device for balancing disc processing. Utility Model Content

[0003] In order to solve the technical problem that only a circular plate with one diameter can be polished, the utility model provides a polishing device for processing a balancing disc.

[0004] The utility model is implemented by the following technical scheme: a grinding device for balancing disc processing, comprising a frame, two lifting cylinders are symmetrically arranged on the upper rear side of the frame, a lifting plate is installed on the top of the push rod of the lifting cylinder, a lateral moving module is installed on the lifting plate, a longitudinal moving module is installed on the slider of the lateral moving module, a motor mounting frame is installed on the slider of the longitudinal moving module, a grinding motor is installed on the motor mounting frame, and a grinding head is installed on the output shaft of the grinding motor;

[0005] A placement plate is suspended above the frame through a bracket, four support pads distributed in a cross shape are slidably arranged above the placement plate, and an air suction port is opened on the support pad, and a suction nozzle is embedded in the air suction port.

[0006] As a further improvement of the above scheme, a dust suction pipe is also provided on the motor mounting frame, the bottom end of the dust suction pipe is located above the front side of the grinding head, and the top end of the dust suction pipe is provided with a dust suction connector, which can be connected to an external suction pipe, and the other end of the suction pipe can be connected to the air inlet of an external vacuum cleaner, so that the debris and dust generated during grinding can be sucked away through the dust suction pipe.

[0007] As a further improvement of the above scheme, four adjustment slide holes distributed in a cross shape are opened above the frame, and a guide slider is extended downward from the lower end of the support pad, and the guide slider passes through the adjustment slide hole and is placed under the placement plate. The position of the support pad can be changed as needed, and a variety of balancing disks or discs or rings of different sizes can be placed and supported.

[0008] As a further improvement of the above scheme, the upper end surface of the support pad is placed 1-3 cm above the placement plate, and the four support pads move independently along the corresponding adjustment slide holes. The bottom end of the balance plate above the support pad is at a certain distance from the top of the placement plate, and the grinding head can grind its side without contacting the placement plate and causing damage.

[0009] As a further improvement of the above scheme, four guide rods distributed in a cross shape are arranged under the placement plate, and the guide slider is slidably sleeved on the guide rod through a sliding hole, and a screw hole is also opened on the guide slider, the screw hole is connected to the sliding hole, and a locking bolt is connected to the inner thread of the screw hole, and the inner end of the locking bolt is in close contact with the guide rod. By loosening the locking bolt, the guide slider can move straight along the guide rod, thereby changing the position of the support pad, and it can be fixed by tightening the locking bolt.

[0010] As a further improvement of the above scheme, the lower end of each suction nozzle is connected to an independent air pipe, the tail ends of the four air pipes are connected to a main pipe, and the tail end of the main pipe is connected to the air inlet end of the vacuum air pump. The vacuum air pump is placed inside the frame. The vacuum air pump can generate suction for each suction nozzle through the main pipe and four air pipes, thereby adsorbing and fixing the balance plate placed on the support pad. The air pipe is relatively long and has good flexibility, which makes it easy for the air pipe to move with the support pad.

The support pads 62 are provided with air suction ports 621, and a suction nozzle is embedded in the air suction ports 621.

[0025] A dust suction pipe 8 is also provided on the motor mounting frame 71. The bottom end of the dust suction pipe 8 is located above the front side of the grinding head 72, and a dust suction connector 81 is provided at the top end of the dust suction pipe 8. The dust suction connector 81 can be connected to an external suction pipe 65, and the other end of the suction pipe 65 can be connected to the air inlet of an external vacuum cleaner.

[0026] Four cross-shaped adjustment slide holes 61 are provided above the frame 1, and a guide slider 64 is provided downwardly extending from the lower end of the support pad 62. The guide slider 64 passes through the adjustment slide hole 61 and is placed under the placement plate 6. The position of the support pad 62 can be changed as needed, and a variety of balancing disks or discs or rings of different sizes can be placed and supported.

[0027] The upper end surface of the support pad 62 is placed 1-3 cm above the placement plate 6, and the four support pads 62 move independently along the corresponding adjustment slide holes 61. The bottom end of the balance plate above the support pad 62 has a certain distance from the top of the placement plate 6. The grinding head 72 can grind its side without contacting the placement plate 6 and causing damage.

[0028] Four guide rods 63 distributed in a cross shape are arranged under the placement plate 6. The guide slider 64 is slidably sleeved on the guide rod 63 through a sliding hole, and a screw hole is also opened on the guide slider 64.
