Description

Technical Field

[0001] The invention relates to the field of mechanical processing, and in particular to a grinding device. Background Art

[0002] A large-diameter shell of a certain model has a length of 3 meters, a wall thickness of 20 mm, an inner wall tolerance of 0-0.2 mm, and a roughness requirement of 1.6Ra. The machining method for processing the inner wall is: using an extended turning tool bar (effective length greater than 1.6 meters) to turn from both ends of the shell to the middle. After turning, the inner wall of the shell is not smooth, and the inner diameter tolerance of 0.2 and the roughness of 1.6Ra do not meet the requirements. After analysis, the reason for the uneven inner wall of the shell is: the tool bar is long, and cutting vibration is generated during the processing, resulting in chatter marks on the machined surface. As a result, the roughness value of the inner wall of the shell does not meet the process requirements.

[0003] There is currently no effective solution to the problem that the roughness value of the inner wall of the shell in the prior art does not meet the process requirements. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a grinding device that can be clamped by a turning rod head. After turning is completed, the inner wall of the shell is grinded by the grinding wheel of the grinding device, thereby solving the problem that the roughness value of the inner wall of the shell does not meet the process requirements.

[0005] To achieve the above-mentioned purpose, the present invention provides a grinding device, including: a support, which is used to connect the rod head; a connecting plate, which is connected to the support; a motor, which is connected to the connecting plate; a connecting seat, which is connected to the support; a transmission shaft, one end of which is arranged in the connecting seat, and the other end passes through the grinding wheel, and a pulley is connected to the outside of the transmission shaft; and a belt, which is jointly sleeved on the outside of the pulley and the outside of the power shaft of the motor.

[0006] Further optionally, a U-shaped groove is provided on the connecting plate; a screw passes through the U-shaped groove and is connected to the motor for adjusting the height of the motor.

[0007] Further optionally, both end faces of the grinding wheel are provided with anti-slip rings; the transmission shaft passes through one of the anti-slip rings, the grinding wheel and the other anti-slip ring in sequence.

[0008] Further optionally, the connecting seat is cylindrical and has a sealing structure.

[0009] Further optionally, the support is connected to the handlebar head via a mounting seat.

[0010] Further optionally, the mounting seat includes a vehicle bar connecting end connected to the vehicle bar head and a support connecting end connected to the support; the vehicle bar connecting end is provided with a mounting boss; the support connecting end is provided with two clips arranged opposite to each other, and the support is fixedly connected to the clips.

[0011] Further optionally, the clip is connected to the support via screws.

[0012] The above technical solution has the following beneficial effects: it can be quickly installed on the turning rod head and can be quickly removed from the turning rod head, which is easy to use; the grinding function can be completed after the shell is turned, expanding the performance of the processing equipment; the same tool bar is used to realize both turning and grinding processes, thereby improving the processing accuracy and efficiency; it effectively overcomes the problem of insufficient rigidity of the long turning tool bar, which causes processing chatter marks on the inner wall of the shell.

A portion of the transmission shaft 6 is arranged inside the connecting seat 7, and another portion protrudes from the connecting seat 7 and passes through the grinding wheel 5. A pulley is also arranged between the grinding wheel 5 and the connecting seat 7, and the belt 4 is jointly sleeved on the outside of the pulley and the outside of the power shaft of the motor 3, so that when the motor 3 is started, the power shaft drives the belt 4, drives the grinding wheel 5 to rotate, and completes the grinding of the inner wall of the shell.

[0023] As an optional implementation, a U-shaped groove is provided on the connecting plate 2; a screw passes through the U-shaped groove and is connected to the motor 3 for adjusting the height of the motor 3.
