[0002] Prostheses can be roughly divided into upper limb prostheses and lower limb prostheses. A very important link in the production process of prostheses is the production of the socket. The shape and size of each socket are different and are irregular. The prosthetic socket needs to be repeatedly trimmed and polished by technicians to match the patient's residual limb and make the patient comfortable to wear. In the process of correcting and polishing the prosthetic socket, a grinder is needed. The existing grinders are all industrial types, which are not only inconvenient to operate, but also have less adjustable freedom, which is not conducive to the grinding of irregular sockets. In addition, the dust removal effect is not good. The socket will produce a lot of gypsum and other dust and pungent odor when grinding, which will endanger health. Therefore, it is necessary to design a multifunctional dust removal grinder that can meet the irregular inner diameter of the prosthesis. Summary of the invention

DETAILED DESCRIPTION

[0021] The present invention is described in detail below in detail with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, a multifunctional dust removal and grinding machine for artificial limb processing includes a base plate 1, and an emergency stop switch 11 is arranged on the bottom surface next to the base plate. An inner frame 2, a lifting base 12 and a vacuum cleaner 4 are arranged on the base plate 1. The lifting base 12 is arranged inside the inner frame 2 and is surrounded and protected by the inner frame 2. The upper end of the lifting base 12 extends from the top of the inner frame, and the lifting base 12 can be extended upward or retracted downward by a certain distance in the vertical direction under the control of the lifting motor. An inner ring 13 with a flange is fixedly connected above the lifting base 12, with the flange at the bottom and the inner ring facing upward; an outer ring 14 with a flange is coaxially sleeved outside the inner ring, with the flange at the top and the outer ring facing downward, so that the outer ring can cover the inner ring, and the outer ring can rotate in a plane relative to the inner ring.

[0023] A cylinder 16 is fixedly arranged at the center of the outer ring flange, a cover plate 15 is arranged above the outer ring flange, the cylinder 16 passes through the center of the cover plate 15, an L-shaped tray 6 is fixedly connected above the cylinder 16, the L-shaped tray 6 includes a horizontal plane and a vertical plane, a grinding motor 5 is arranged on the horizontal plane of the tray, the front end bottom of the grinding motor 5 is rotatably connected to the horizontal plane of the tray 6 through a rotating shaft 53, a grinding head is installed on the output shaft 54 ​​of the grinding motor 5, the grinding head includes a large grinding head 51 and a small grinding head 52, the large grinding head is sleeved in the middle of the motor output shaft, and the small grinding head is arranged at the end of the motor output shaft. The output shaft 54 ​​of the grinding motor 5 is conical, and the inner side of the large grinding head is also conical, which can make the installation of the large grinding head convenient and quick; the end of the output shaft 54 ​​has a silk pattern, which is convenient for installing the small grinding head. The L-shaped tray is also connected with a lighting 55 to facilitate the observation of the grinding position. An arc groove 61 is provided on the vertical surface of the L-shaped tray 6, and a screw wrench 62 is provided in the arc groove 61. The screw wrench 62 passes through the arc groove and is fixedly connected to the grinding motor 5. By operating the screw wrench to move in the arc groove, the grinding motor can be rotated around the horizontal plane of the tray so that the grinding head can be raised or lowered in the vertical plane, which is convenient for adjusting the pitch angle and better adapting to the needs of grinding inside the receiving cavity.

[0024] Specifically, a downward peripheral frame 3 is arranged around the cover plate 15, and the peripheral frame 3 surrounds the inner frame 2. The lower edge of the peripheral frame 3 is at a certain distance from the bottom plate 1, so that the peripheral frame, the inner frame and the cover plate together surround and protect the lifting base, while not affecting the lifting function of the lifting base.

Whether the friction pad 331 presses the outer ring 14 can control the rotation of the outer ring. For example, after the grinding motor and the grinding head are rotated to a suitable angle in the plane, the grinding motor can be fixed by tightening the friction pad and the outer ring by locking the top screw, which is convenient for the grinding needs of the special-shaped space inside the receiving cavity.

[0025] In order to remove the dust generated during the grinding process in time, the vacuum cleaner 4 on the bottom plate is provided with a first vacuum pipe 43, a second vacuum pipe 45 and a third vacuum pipe 41, wherein the head of the first vacuum pipe 43 is connected to the vacuum nozzle 44 at the grinding head, which is close to the large grinding head and the small grinding head, and plays a major role in vacuuming. The head of the second vacuum pipe 45 is connected to the sleeve vacuum device 46, which is installed at the root of the output shaft of the grinding motor. There is a gap between its vacuum nozzle and the motor output shaft, which can remove part of the dust and play a secondary role in vacuuming. The head of the third vacuum pipe 41 is connected to the bottom vacuum nozzle 42, which is close to the ground directly below the grinding head, and can remove a small amount of grinding dust that falls on the ground again. The vacuum cleaner is electrically connected to the control panel.
