[0002] A polishing machine is an electric tool. It consists of a base, a polishing disc, a polishing fabric, a polishing cover and a cap. The key to the operation of a polishing machine is to try to get the maximum polishing rate so as to remove the damaged layer generated during polishing as quickly as possible. At the same time, the polishing damaged layer should not affect the final observed structure, that is, it will not cause false structure. The former requires the use of coarser abrasives to ensure a higher polishing rate to remove the polished damaged layer, but the polishing damaged layer is also deeper; the latter requires the use of the finest material to make the polishing damaged layer shallower, but the polishing rate is low.

[0003] The inventor of this application found that there are the following problems in the practical use process:

DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention. Example

[0022] like Figure 1-4 As shown, the utility model is a polishing machine with a quick-release function, comprising a base 2 and a dual-axis motor 5, the two output shafts of the dual-axis motor 5 are fixedly connected with a connecting shaft 6, one end of the connecting shaft 6 is fixedly connected with a connecting head 11, the front and rear surfaces of the connecting head 11 are provided with a fixing groove 12, and the upper surface of the connecting head 11 is provided with a through hole 8, the interior of the connecting head 11 is plugged with a connecting block 14, the upper surface of the connecting block 14 is provided with a pin hole 10, and a polishing disc 7 is fixedly installed on one side of the connecting block 14, the interior of the through hole 8 is plugged with a pin 9 passing through the pin hole 10, and the outer side of the pin 9 is symmetrically fixedly installed with an elastic clamping piece 13 engaged with the fixing groove 12.

[0023] like Figure 2 As shown, the elastic clamping member 13 is in an L-shaped structure, and the elastic clamping member 13 is made of an elastic steel sheet, so that the elastic clamping member 13 has a certain elastic bending ability.

[0024] like Figure 2 As shown, the pin 9 is in a T-shaped structure, and the pin 9 and the elastic clamping piece 13 are an integrally formed structure, so that the pin 9 and the elastic clamping piece 13 are firmly connected, and the connecting block 14 is in a rectangular structure.

[0025] During implementation, the polishing disc 7 and the connecting shaft 6 are connected by a connecting block 14 and a connecting head 11. The elastic clamping piece 13 is pulled to make it elastically bend, so that the elastic clamping piece 13 is controlled to be disengaged from the inside of the clamping groove 12, and the pin 9 is taken out from the pin hole 10 opened in the connecting block 14, thereby facilitating the disassembly of the polishing disc 7. This solves the technical problem that the polishing machine in the prior art usually installs and fixes the polishing disc 7 and the output shaft of the power mechanism, but lacks a structure for convenient disassembly, resulting in troublesome disassembly of the polishing disc 7 and inconvenience in replacement after severe wear. Example

[0026] like Figure 1-4 As shown, on the basis of the first embodiment, the utility model provides a technical solution: a bottom plate 1 is fixedly installed on the bottom of the base 2, four fixing holes 4 are evenly opened on the upper surface of the base plate 1, telescopic columns 17 are symmetrically fixedly installed on the upper surface of the base 2, and a support shell 3 connected to the dual-axis motor 5 is fixedly installed on the upper ends of the two telescopic columns 17, a servo motor 15 is fixedly installed on the upper surface of the base 2, and a screw rod 18 is fixedly connected to the output shaft of the servo motor 15, and a threaded tube 16 is screwed on the outer side of the screw rod 18, and the upper end of the threaded tube 16 is fixedly connected to the support shell 3, the connecting block 14 is a rectangular structure, and the connecting block 14 and the polishing disk 7 are an integrally formed structure.

[0027] During implementation, the support shell 3 and the base 2 are movably connected by a telescopic column 17. By starting the servo motor 15, the screw rod 18 connected to its output shaft is driven to rotate, and the outer threaded tube 16 is controlled to drive the support shell 3 to rise and fall, thereby facilitating the adjustment of the height of the polishing disc 7 according to needs, facilitating use by different users, and improving adaptability.

[0028] When the polishing disc 7 needs to be disassembled in the technical solution, the elastic fastener 13 is first pulled to bend elastically, so that the convex part of the lower end is separated from the bottom of the connector 11, and then the lower end of the pin 9 is taken out from the through hole 8 and the pin hole 10. At this time, the elastic fastener 13 is separated from the inside of the fastening groove 12, and finally the polishing disc 7 is removed to separate the connecting block 14 connected thereto from the inside of the connector 11. When the height of the polishing disc 7 needs to be adjusted, the servo motor 15 is started to drive the screw rod 18 connected to its output shaft to rotate, drive the outer threaded tube 16 to drive the support shell 3 to rise and fall, and then drive the polishing disc 7 to rise and fall.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
