Description

Technical Field

[0001] The present invention relates to the technical field of polishing machines, and in particular to a polishing machine with a workpiece rotary support device. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical actions to reduce the surface roughness of a workpiece to obtain a bright and flat surface. It is a finishing process that uses a polishing machine and abrasive particles or other polishing media to process the surface of the workpiece.

[0003] However, when the existing polishing machine polishes the side of a columnar workpiece, only one side can be polished after each fixation. After one side of the workpiece is polished, it needs to be disassembled, the polishing surface of the workpiece is adjusted, and then it is fixed again. The above steps need to be repeated multiple times for multi-sided polishing of a single workpiece, which not only increases the work difficulty of the staff, but also reduces the production efficiency. In addition, dust is easily generated during the polishing process, resulting in pollution of the workshop. In addition, polishing will also generate debris on the workbench, and workshop workers need to clean the debris on the workbench. The cleaning workload is relatively large, and the manual cleaning efficiency is also relatively low. Summary of the Invention

[0045] Refer to Figure 1 , Figure 2 , Figure 11 and Figure 12, the first motor 12 on the side plate 11 drives the first screw rod 13 to perform a rotational motion. The first threaded block 14 on the first screw rod 13 realizes a reciprocating motion under the action of the connecting plate 15, the T-shaped connecting block 16 and the T-shaped connecting groove. The first threaded block 14 will drive the moving frame 70 to move to the top of the workpiece.

[0046] Working principle: By placing the columnar workpiece at the center of the top of the clamping frame 40, the bidirectional motor 43 drives the second screw rod 44 to perform a rotational motion. During the rotation of the second screw rod 44, the second threaded block 42 realizes a relative motion under the action of the clamping rod 45 and the clamping groove 46. During the relative motion, the second threaded block 42 drives the arc-shaped clamping block 41 to clamp and fix the workpiece through the clamping rod 45 and the clamping groove 46, so that the workpiece is firmly clamped at the center of the top of the clamping frame 40. The arc-shaped clamping block 41 cooperates with the second screw rod 44 and the second threaded block 42 to realize the centered clamping of the workpiece. The clamping of the arc-shaped clamping block 41 is stable and smooth, and the clamping effect of the arc-shaped clamping block 41 is good.

[0047] The first motor 12 on the side plate 11 drives the first screw rod 13 to perform a rotational motion. The first threaded block 14 on the first screw rod 13 realizes a reciprocating motion under the action of the connecting plate 15, the T-shaped connecting block 16 and the T-shaped connecting groove. The first threaded block 14 will drive the moving frame 70 to move to the top of the workpiece. The fourth motor 72 in the moving frame 70 drives the fourth screw rod 73 to perform a rotational motion. The moving block 71 on the fourth screw rod 73 realizes a reciprocating motion under the limiting action of the moving rod 74 and the moving groove 77. The moving block 71 will also drive the polishing body 20 under the first hydraulic telescopic rod 75 to adjust the front and rear positions through the moving rod 74 and the moving groove 77, so that the polishing disc 76 at the bottom of the polishing body 20 polishes the side of the workpiece. The height of the polishing disc 76 is adjusted by the first hydraulic telescopic rod 75. The position and height of the polishing disc 76 are conveniently and stably adjusted through the moving frame 70 and the first hydraulic telescopic rod 75, meeting the polishing and grinding of different workpieces and improving the practical performance of the device.

[0048] During the entire grinding and polishing process, the second motor 33 inside the rotating frame 30 drives the driving gear 32 to perform a rotational movement. The driving gear 32 meshes with and drives the rotating tooth disc 31 on the rotating base ring 34 to perform a synchronous rotational movement. The rotating tooth disc 31 drives the clamping frame 40 to perform a rotational movement at the bottom of the polishing disc 76 through the rotating column 37, realizing the annular polishing and grinding of the workpiece. During the rotation of the rotating tooth disc 31, a stable and smooth rotational movement is achieved through the rotating base ring 34, the rotating base chute 35, and the rotating base slider 36. There will be no shaking during the rotational grinding and polishing process, improving the grinding and polishing quality of the workpiece.

[0049] During the polishing and grinding process, the dust suction fan 80 connected to the bottom of the connecting plate 15 through the second hydraulic expansion rod 81 absorbs the dust generated during the polishing and grinding. The dust after suction enters the dust suction cylinder 82 through the dust suction pipe 84 for absorption and purification, and the air after purifying the dust is discharged. The dust particles are filtered by the dust suction filler 83 inside the dust suction cylinder 82. The height of the dust suction fan 80 is adjusted through the second hydraulic expansion rod 81, so that the dust suction fan 80 can stably and effectively absorb the dust generated by the polishing disc 76, and the dust suction position can be adjusted. The dust suction pipe 84 cooperates with the dust suction holes 18 to move synchronously with the first threaded block 14, realizing dust suction and air purification while polishing and grinding, and purifying the working environment of the workshop processing.

[0050] When the first motor 12 drives the first screw rod 13 to perform a rotational movement, the first screw rod 13 drives the second bevel gear 63 to perform a rotational movement through the connecting rotating shaft 52. The second bevel gear 63 meshes with the first bevel gear 62 inside the connecting box 60 to drive the support rotating shaft 61 to perform a rotational movement. The third bevel gear 64 at the top of the support rotating shaft 61 moves synchronously. The third bevel gear 64 meshes with the fourth bevel gear 65 to drive the third screw rod 54 to perform a rotational movement. The cleaning threaded block 53 on the third screw rod 54 realizes a reciprocating movement under the action of the first positioning rod 55. During the reciprocating movement of the cleaning threaded block 53, the cleaning seat 51 is driven to move back and forth through the cleaning rod 56 and the cleaning groove 57. The cleaning nozzle 58 on the cleaning seat 51 cooperates with the blower 59 to centrally clean the debris generated on the top of the processing box 10, blowing the debris on the top of the processing box 10 to one end for centralized treatment, improving the cleaning efficiency of the processing box 10, and at the same time reducing the labor intensity of the workshop workers.

[0051] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to this. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
