Description

Technical Field

[0001] The utility model relates to the field of polishing machines, in particular to a circular polishing machine. Background Art

[0002] Ring polishing machine is a kind of mechanical equipment used for surface finishing, mainly used for polishing and grinding hard materials such as metal, glass, ceramics, etc. This machine is particularly suitable for processing annular or circular workpieces such as bearing rings, optical components, etc.

[0003] A toroidal polishing machine typically consists of a rotating polishing plate and one or more fixtures to hold the workpiece. The workpiece is fixed to a central axis, while the polishing plate rotates around the workpiece, or the workpiece itself can rotate. During the polishing process, the polishing plate is coated with polishing paste or sprayed with polishing liquid. This removes minute amounts of material from the workpiece surface through physical friction or chemical reaction, achieving a smooth finish.

[0004] In some fixed polishing machines, specific parts cannot reach certain areas of the workpiece due to design limitations of the polishing device, resulting in these areas not being effectively polished, leaving dead corners. Since the workpiece position needs to be adjusted multiple times to ensure that all parts can be polished, the repeated positioning and adjustment in the traditional polishing process greatly reduces the operating efficiency.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

The planetary rotating wheel contacts the outer peripheral surface of the center wheel, and the turntable assembly 3 and the grinding belt wheel group 4 are both existing technologies and will not be described in detail here.

[0027] At the same time, it should be added that six grinding wheels are installed on the front side of the turntable assembly 3, and several synchronous pulleys corresponding to the six grinding wheels are installed on the back side, so as to ensure normal engagement between the gears when passing through the opening and entering the opening.

[0028] In one embodiment, for the above-mentioned tightening and fixing device 8, the tightening and fixing device 8 includes a motor 801 arranged on one side of the bottom end of the body 1, and a bevel gear 802 is provided at one end of the output shaft of the motor 801, and a bevel gear 803 meshing with the bevel gear 802 is provided on one side, and a connecting rod 804 is provided at the top of the middle part of the bevel gear 803, and a reinforcing member 805 is provided at the top of the connecting rod 804. The reinforcing member 805 includes a mounting plate 8051 arranged at the top of the connecting rod 804, and a limiting column 8052 is provided at the top of the mounting plate 8051.

[0029] The working principle of the tightening and fixing device 8 is as follows: under the control of the external controller, the motor 801 is controlled and started, and the output end of the motor 801 drives the bevel gear 1 802 to rotate, and the bevel gear 1 802 is used to drive the meshing bevel gear 2 803 to rotate, and during the rotation of the bevel gear 2 803, the connecting rod 804 is driven to rotate, and during the rotation of the connecting rod 804, the limiting column 1 8052 at the top of the mounting plate 8051 is used to rotate, thereby achieving the limitation of the processed ring and ensuring the stability of the processed ring during the polishing process.

[0030] In one embodiment, for the above-mentioned limit assembly 10, the limit assembly 10 includes a mounting plate 1001 arranged on one side of the top of the workbench 5, a cylinder 1002 is arranged on one side of the top of the mounting plate 1001, and the output end of the cylinder 1002 is provided with a sliding block 1003 that cooperates with the mounting plate 1001, and a limit column 1004 is provided on the top of the sliding block 1003. Therefore, under the action of the limit assembly 10, not only the precise positioning and safety and stability of the workpiece are guaranteed, but also the operation process is simplified, the surface quality of the workpiece is greatly improved, and the product is smoother, more durable and more beautiful.

[0031] The working principle of the limiting component 10 is as follows: under the control of the external controller, the cylinder 1002 is controlled and started, and the sliding block 1003 is driven to slide on the surface of the mounting plate 1001 under the action of the output end of the cylinder 1002, and the limiting column 1004 at the top of the mounting plate 1001 is used to limit the processed ring and ensure the stability of the processed ring during the polishing process.

[0032] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0033] In actual application, before starting polishing, the processed ring is placed on the workbench and fixed by the tightening and fixing device 8. The turntable assembly is started, so that the large turntable rotates around the central axis. At the same time, the abrasive wheel group 4 is started through the abrasive belt transmission mechanism. The abrasive belt polishes the surface of the workpiece under the drive of the active and passive wheels. The limit assembly 10 ensures that the workpiece maintains the correct position during the polishing process through the sliding block and limit column operated by the cylinder.

[0034] The working principles of the tightening and fixing device 8 and the limiting assembly 10 are as described above.
