Description

Technical Field

[0001] The invention relates to the technical field of hollow shaft processing, in particular to a grinding device for hollow shaft molding. Background Art

[0002] Hollow shafts are often used instead of solid shafts in some equipment fields that have high acceleration performance requirements and are sensitive to equipment quality because of their small shaft mass and high rotational acceleration efficiency.

[0003] At present, most grinding devices are mainly used for solid shaft grinding. Hollow shaft grinding cannot be directly ground using solid shaft grinding devices due to its large diameter. Most of the current hollow shaft grinding devices use large digital grinders, which makes it inconvenient when temporary on-site grinding is required. In addition, large grinders are complicated to operate and have a long processing cycle. Therefore, in order to solve such problems, we propose a grinding device for hollow shaft forming. Summary of the invention

[0004] The invention provides a hollow shaft forming grinding device, which solves the problems of the existing hollow shaft grinding devices being large in size, high in cost and inconvenient to move.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The cam is an axially parallelogram of the second engagement of the first and second engagements of the first and second engagements of the second engagements, wherein the first and second engagements of the first and second engagements of the second engagements are axially parallelogrammed. A spring seat is fixedly installed, and a clamping spring is fixedly installed on one end of the spring seat away from the second rotating shaft, and an end of the clamping spring away from the spring seat and an end of the first rotating shaft close to the second clamping plate are both fixedly installed with an axle body fixing seat, a hollow shaft is fixedly installed between the two axle body fixing seats, an upper surface of the base is provided with a grinding seat groove along its length direction, and a grinding seat is slidably installed inside the grinding seat groove, an end of the grinding seat away from the base is hinged with a rotating column, and a motor is fixedly installed on one side of the rotating column, and a grinding wheel shaft is fixedly installed on the end of the output shaft of the motor away from the motor, the grinding wheel shaft passes through the rotating column, and a grinding wheel disc is fixedly installed on the end of the grinding wheel shaft away from the motor.

[0007] Preferably, symmetrically distributed limiting telescopic rods are fixedly installed between the spring seat and the shaft body fixing seat.

[0008] Preferably, the second rotating shaft passes through the second clamping plate, and a rotating handle is fixedly mounted on one end of the second rotating shaft away from the first clamping plate.

[0009] Preferably, symmetrically distributed spring fixing blocks are fixedly installed on one side of the rotating column and the grinding seat, and a return spring is fixedly installed between the two spring fixing blocks.

[0010] Preferably, a pressure rod is fixedly mounted on one end of the rotating column away from the grinding seat.

[0011] The beneficial effects of the present invention are as follows: 1. By pushing the second clamping plate, the second clamping plate can slide along the clamping plate slot, so that the second clamping plate pushes the one-side shaft body fixing seat to move toward the direction of the first clamping plate, thereby clamping the hollow shaft. By rotating the locking bolt, the position of the second clamping plate is fixed, and a clamping spring is fixedly installed between the one-side shaft body fixing seat and the spring seat, so that the hollow shaft is clamped under the elastic force of the clamping spring, so that the device is convenient for disassembly and assembly of the hollow shaft body, and the hollow shaft is not easy to loosen during grinding. 2. By fixing a rotating handle at one end of the second rotating shaft away from the spring seat, the rotation of the hollow shaft can be achieved by adjusting the rotating handle, and the grinding seat is slidably connected to the grinding seat groove, so that the sanding disc can slide along the length direction of the grinding seat groove, so that the device can grind the surface of the hollow shaft at different positions, and the device has a relatively simple structure and is easy to move and carry.

[0012] In summary, the device is not only convenient for disassembly and assembly of the hollow shaft, but also prevents the hollow shaft from loosening during grinding. Moreover, the device can grind the surfaces of different positions of the hollow shaft and is easy to move and transport, so it is suitable for promotion. BRIEF DESCRIPTION OF THE DRAWINGS
