Description

Technical Field

[0001] The utility model relates to the technical field of cloth wheel polishers, in particular to an automatic cloth wheel polisher with adjustable pressure. Background Art

[0002] Cloth wheel polishing machines are often used in mechanical polishing and waxing operations. Their working principle is: the motor drives the sponge or wool polishing disc installed on the transmission shaft to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer, and shallow marks can be removed. The speed of the polishing machine is generally 1500-3000r / min, most of which are stepless speed change, and can be adjusted at any time according to needs during construction.

[0003] The existing cloth wheel polishing machines have the following main disadvantages during use: the material and hardness of the cloth wheel will directly affect the polishing effect. Therefore, when polishing different materials, cloth wheels of different materials and hardness need to be replaced. However, the existing cloth wheel polishing machines require manual disassembly of the cloth wheel and replacement of new cloth wheels, which is troublesome, time-consuming and labor-intensive, and affects the polishing efficiency. Therefore, there is room for improvement. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0022] Embodiment 1:

[0023] Combination Figure 1-4 As shown, this embodiment provides an adjustable pressure automatic cloth wheel polishing machine, including: a main body module 100.

[0024] Among them, the main module 100 includes a base plate 110, two slides 120 slidably arranged at the top of the base plate 110, a first motor 130 installed at the top of the slide 120, an electric telescopic rod 140 fixed on the base plate 110 and whose end is fixedly connected to the slide 120, a plurality of driving members 150 installed on one side of the base plate 110 and extending into the base plate 110, a threaded sleeve 160 sleeved on the driving member 150, a U-shaped frame 170 fixed at the top of the threaded sleeve 160, a semi-ring plate 180 fixed to the top of the U-shaped frame 170 by bolts, and a cloth wheel body 190 rotatably embedded between the semi-ring plate 180 and the U-shaped frame 170.

[0025] The base plate 110 is used to install other components and maintain the stability of each component. A slide groove 112 is symmetrically opened at the top of the base plate 110. At the same time, a slide bar 121 is set at the bottom end of the slide plate 120. The slide bar 121 is slidably engaged in the slide groove 112 to limit the movement of the slide plate 120 and ensure the stability of the movement of the slide plate 120.

[0026] The slide plate 120 is used to install the first motor 130 and drive the first motor 130 to move. The first motor 130 is used to drive the cloth wheel body 190 to rotate. The electric telescopic rod 140 is fixed on the base plate 110, and the end is fixed to one side of the slide plate 120, which is used to drive the slide plate 120 to move, that is, drive the first motor 130 to move.

[0027] A plurality of grooves 111 are arranged in an array at the top of the base plate 110, and the driving member 150 includes a threaded rod 151 rotatably mounted on the inner wall of the groove 111 and a second motor 152 mounted on one side of the base plate 110 and having its shaft fixedly connected to the end of the threaded rod 151. At the same time, the threaded sleeve 160 is embedded in the groove 111, and the threaded rod 151 passes through the threaded sleeve 160. The threaded rod 151 and the threaded sleeve 160 are meshed with each other, so that when the second motor 152 rotates, it can drive the threaded rod 151 to rotate, and the rotation of the threaded rod 151 drives the threaded sleeve 160 to move, and the movement of the threaded sleeve 160 drives the U-shaped frame 170 to move, thereby driving the cloth wheel body 190 to move, thereby controlling the position of the cloth wheel body 190.

[0028] The U-shaped frame 170 and the semi-ring plate 180 are both used to fix the cloth wheel body 190. A lower semi-ring groove is opened on the relative inner side surface of the U-shaped frame 170, and an upper semi-ring groove is opened on the inner side surface of the semi-ring plate 180. One side of the cloth wheel body 190 is embedded in the lower semi-ring groove, and the other side is embedded in the upper semi-ring groove, which ensures the stability of the cloth wheel body 190 and facilitates the rotation of the cloth wheel body 190.

[0029] In addition, a lower ear plate 171 is symmetrically fixed to the top of the U-shaped frame 170, and a screw hole is opened on the lower ear plate 171. An upper ear plate 181 is symmetrically fixed to the bottom end of the semi-ring plate 180, and a round hole is opened on the upper ear plate 181. Bolts pass through the round holes and engage in the screw holes. The U-shaped frame 170 and the semi-ring plate 180 are connected and fixed by bolt engagement, which facilitates the disassembly of the semi-ring plate 180, that is, it is convenient to disassemble the cloth wheel body 190 from the U-shaped frame 170.

[0030] The material and hardness of the cloth wheel body 190 on each U-shaped frame 170 are different, which is convenient for grinding and polishing products of different materials. A through hole 191 is opened on the cloth wheel body 190, and a rectangular protrusion 192 is fixed on the inner wall of the through hole 191. At the same time, a rectangular groove 131 is opened on the shaft of the first motor 130, and the rectangular protrusion 192 is embedded in the rectangular groove 131, so that after the shaft of the first motor 130 is inserted into the through hole 191, the rectangular protrusion 192 is embedded in the rectangular groove 131. At this time, the rotation of the shaft of the first motor 130 can drive the cloth wheel body 190 to rotate synchronously.

[0031] The working principle and use process of the utility model are as follows: when it is necessary to replace the cloth wheel body 190 of other materials and hardness, the electric telescopic rod 140 is started to drive the slide plate 120 to move, and the movement of the slide plate 120 drives the first motor 130 to move, so that the shaft of the first motor 130 is separated from the through hole 191 on the cloth wheel body 190. At this time, the driving member 150 corresponding to the cloth wheel body 190 is started, and the second motor 152 rotates to drive the threaded rod 151 to rotate, and the rotation of the threaded rod 151 drives the threaded sleeve 160 to move, and the movement of the threaded sleeve 160 drives the U-shaped frame 170 to move, that is, the cloth wheel body 190 is driven to move to one side, and at the same time When the cloth wheel body 190 is replaced, the driving member 150 of the required cloth wheel body 190 is started, driving the U-shaped frame 170 to move, and moving the required cloth wheel body 190 to be in the same straight line with the first motor 130. At this time, the electric telescopic rod 140 is started again, driving the first motor 130 to move toward the required cloth wheel body 190, so that the shaft of the first motor 130 is inserted into the through hole 191 on the required cloth wheel body 190, and the rectangular protrusion 192 on the inner wall of the through hole 191 is embedded in the rectangular groove 131 on the shaft of the first motor 130. The first motor 130 is started, driving the required cloth wheel body 190 to rotate, and the automatic replacement of the cloth wheel body 190 is completed.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
