Description

Technical Field

[0001] The utility model belongs to the technical field of screen shaft processing, and in particular relates to a polishing device used for screen shaft processing. Background Art

[0002] The screen shaft is a component used for screening on the roller screen. Multiple processes are required in the processing of the screen shaft, including cutting, grinding, polishing and other steps, among which polishing is a common processing step.

[0003] When polishing the screen shaft, the existing polishing equipment first fixes the screen shaft workpiece, and then starts the polishing machine to perform the polishing operation. During the polishing process, the linkage between the screen shaft and the polishing machine is poor. After the screen shaft is fixed, it cannot be moved to switch the position toward the polishing machine. Therefore, after polishing a position, it is necessary to adjust and unlock the screen shaft to switch the screen shaft position, and then re-fix and polish. The back-and-forth operation is cumbersome and reduces work efficiency. The back-and-forth operation and adjustment are likely to cause inconsistent polishing accuracy. Utility Model Content

[0004] The utility model aims to provide a polishing device for screen shaft processing, so as to solve the problem that the existing polishing device proposed in the above background technology is to first fix the screen shaft workpiece, and then start the polishing machine to perform the polishing operation. During the polishing process, the linkage between the screen shaft and the polishing machine is poor, and the screen shaft cannot be moved and switched to the position of the polishing machine after being fixed. Therefore, after polishing a position, it is necessary to adjust and unlock the screen shaft to switch the screen shaft position, and then re-fix and polish. The back and forth operation is cumbersome and reduces work efficiency. The back and forth operation adjustment is likely to lead to the problem of inconsistent polishing accuracy.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a polishing device for screen shaft processing, comprising a frame, a bracket is welded and installed on the side of the frame, a cylinder is fixedly installed on the upper surface of the bracket, a mounting seat is fixedly installed on the end of the piston rod of the cylinder, a polishing roller is rotatably installed in the mounting seat, a polishing motor is fixedly installed on the side of the mounting seat, the output shaft of the polishing motor is fixedly connected to one end of the polishing roller, a channel is opened on the frame, and grooves are opened on the left and right sides of the inner wall of the channel, and rotating shafts are rotatably installed on the front and back sides of the inner wall of the groove, and there is a gap between the two rotating shafts. A bidirectional lead screw is fixedly installed, a driving motor is fixedly installed on the side of the frame, the output shaft of the driving motor is fixedly connected to the end of the rotating shaft at the corresponding position, pulleys are fixed on the outer surfaces of the two rotating shafts on the same side, and a belt is connected for transmission between the two pulleys, and sliding blocks 1 are threadedly installed on the outer surfaces of the two sections of the bidirectional lead screw, and the sliding block 1 slides on the inner wall of the groove, and a supporting grinding roller is rotatably installed between the two sliding blocks on the same side and a connecting shell is fixedly installed, the outer surface of the supporting grinding roller is sleeved with two limiting rings, and an adjustment unit for adjusting the position of the limiting ring is provided on the connecting shell.

[0006] The above scheme is adopted, by setting a bidirectional lead screw in conjunction with two supporting grinding rollers, the distance between the two supporting grinding rollers can be adjusted, and the lateral limit of the screen shaft workpiece can be achieved in conjunction with the limit ring, so that the screen shaft workpieces of different specifications and sizes can be limited and clamped to support them, thereby improving universality. In addition, the two supporting grinding rollers and the polishing roller are used in conjunction with each other, the two supporting grinding rollers at the bottom provide support, and the upper polishing roller performs polishing while pressing the screen shaft workpiece, thereby ensuring the stability of the screen shaft workpiece during the polishing process, and the fixing and polishing of the screen shaft workpiece are highly linked, and there is no need for repeated The operation of fixing and releasing the fixation can exchange the position of the screen shaft workpiece, improve the working efficiency, and ensure the good polishing operation accuracy. By using the clamping screw in conjunction with the limit ring to limit and clamp the screen shaft workpiece, if the screen shaft workpiece needs to be rotated, unscrew the clamping screw, and the clamping screw will no longer clamp the screen shaft workpiece. At this time, the screen shaft workpiece can be rotated under the action of the polishing roller and the supporting grinding roller to achieve all-round polishing. If the screen shaft workpiece needs to be polished at a fixed point, screw on the clamping screw to achieve the clamping and fixation of the screen shaft workpiece, and fixed-point polishing can be performed.

[0007] In the above scheme, it should be noted that the cylinder, polishing motor, drive motor and motor are all electrically connected to an external power supply.

[0008] As a preferred implementation, a guide rod is fixedly mounted on the upper surface of the mounting seat, and the guide rod is slidably mounted on the bracket.

[0009] By adopting the above scheme, the setting of the guide rod can support the up and down movement of the mounting seat, thereby ensuring that the polishing roller is not prone to shaking and tilting during the up and down movement, thereby improving the movement stability.

[0010] As a preferred embodiment, two storage boxes are fixedly mounted on the upper surface of the frame, the upper surfaces of the storage boxes have openings, and labels are attached to the sides of the storage boxes.

[0011] By adopting the above solution, the storage box is provided and used in conjunction with the label sticker, so that the workpieces before and after polishing can be stored separately, and the workpieces can be easily taken out for use.

[0012] As a preferred embodiment, the adjusting unit includes a motor fixedly mounted on the inner wall of the connecting shell, a bidirectional screw fixed on the end of the motor output shaft, and two sliding blocks 2 threadedly mounted on the outer surfaces of two sections of the bidirectional screw. The sliding block 2 slides on the inner wall of the connecting shell and is fixedly connected to a limiting ring at a corresponding position. A slideway for the sliding block 2 to move is provided on the side of the connecting shell.

[0013] By adopting the above scheme, a motor is used to drive the bidirectional screw to rotate, thereby driving the two sliding blocks to drive the two limit rings to move synchronously relative to each other, thereby being able to laterally limit the screen shaft workpiece to avoid lateral deviation during polishing.

[0014] As a preferred embodiment, a support shaft is fixedly mounted on one end of the bidirectional screw away from the motor, and the support shaft is rotatably mounted on the inner wall of the connecting shell.

[0015] By adopting the above solution, the setting of the support shaft can support the bidirectional screw, avoid the centrifugal shaking during the rotation of the bidirectional screw, and improve the rotation stability.

[0016] As a preferred implementation, a threaded hole is provided on the limiting ring, and a clamping screw is threadedly installed on the inner wall of the threaded hole.

[0017] The above scheme is adopted and used in conjunction with the clamping screw. When the limit ring is used to limit and clamp the screen shaft workpiece, if the screen shaft workpiece needs to be rotated, the clamping screw is unscrewed and the clamping screw no longer clamps the screen shaft workpiece. At this time, the screen shaft workpiece can be rotated under the action of the polishing roller and the supporting grinding roller to achieve all-round polishing. If the screen shaft workpiece needs to be polished at a fixed point, the clamping screw is screwed on to achieve the clamping and fixation of the screen shaft workpiece, so that fixed-point polishing can be performed.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

The two supporting grinding rollers and the polishing roller are used in conjunction with each other, the two supporting grinding rollers at the bottom provide support, and the upper polishing roller performs polishing while pressing the screen shaft workpiece, thereby ensuring the stability of the screen shaft workpiece during the polishing process, and the fixing and polishing linkage of the screen shaft workpiece is strong, and there is no need to repeatedly fix and release the fixing to replace the position of the screen shaft workpiece, thereby improving the working efficiency and ensuring good polishing operation accuracy.

[0020] The polishing equipment used for screen shaft processing is used in conjunction with a clamping screw. When a limiting ring clamps the screen shaft workpiece, if the screen shaft workpiece needs to be rotated, the clamping screw is unscrewed, and the clamping screw no longer clamps the screen shaft workpiece. At this time, the screen shaft workpiece can be rotated under the action of the polishing roller and the supporting grinding roller to achieve all-round polishing. If the screen shaft workpiece needs to be polished at a fixed point, the clamping screw is screwed on to achieve clamping and fixing of the screen shaft workpiece, so that fixed-point polishing can be performed.
