Description

Technical Field

[0001] This utility model belongs to the field of dental prosthesis manufacturing technology, and specifically relates to a grinding device for dental prosthesis manufacturing. Background Technology

[0002] The production of dentures is a complex process that combines medicine, materials science, and precision manufacturing technology, aiming to provide patients with restorations that are both functional and aesthetically pleasing. Denture polishing is a key step in denture production, directly affecting the comfort, aesthetics, and lifespan of the dentures. Therefore, the polishing process is extremely important during denture production.

[0003] Existing denture grinding devices work by placing the denture to be ground in a designated position, then using a traveling mechanism to drive a rotating grinding head close to the denture to grind it, thereby eliminating processing marks, ensuring a smooth occlusal surface and rounded edges, and avoiding irritation to the oral soft tissues. However, in actual use, the relatively simple adjustment of the grinding head's position makes it difficult for the grinding head to adapt well to the shaping of denture edges, gingival margins, and occlusal grooves and pits. This necessitates further fine-tuning with handheld power tools, which is inconvenient and adds to the processing burden, affecting denture processing efficiency. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a grinding device for denture production. By adjusting the horizontal position, vertical position, tilt angle, and distance from the denture of the grinding head, it can adapt well to the position on the denture that needs to be ground, thereby enabling rapid and stable precise grinding of the denture to be ground.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a grinding device for denture production, including a frame, a guide rail on the frame, a slide table slidably mounted on the guide rail, a slide cylinder slidably mounted on the slide table, a slide column slidably mounted on the outer side of the slide cylinder, a rotating seat at the top of the slide column, a slide cylinder rotatably mounted on the rotating seat via a rotating shaft, a slide rod slidably mounted inside the slide cylinder, a grinding mechanism at the end of the slide rod away from the slide cylinder, the grinding mechanism being used to grind dentures, and a driving mechanism inside the rotating seat being used to adjust the grinding angle.

[0006] As a further improvement of this utility model, the driving mechanism includes an adjusting screw two rotatably disposed inside the lower side of the rotating seat, a driving seat threadedly connected to the outer side of the adjusting screw two, driving columns disposed on both sides of the driving seat, symmetrically distributed driving plates fixedly sleeved on the outer arc surface of the rotating shaft, and sliding grooves opened on the lower side of the driving plates slidingly connected to adjacent driving columns. A motor five is disposed on the rear side of the rotating seat, and the output shaft of the motor five is fixed to the adjusting screw two by a coupling. An adjusting screw one is rotatably disposed inside the sliding cylinder, and the adjusting screw one is threadedly connected to the sliding rod. A motor four is disposed on the outer side of the sliding cylinder, and the output shaft of the motor four is fixed to the adjusting screw one by a coupling. The grinding mechanism includes a grinding box disposed at the end of the sliding rod away from the sliding cylinder, a motor two is disposed inside the grinding box, and a grinding head is fixedly sleeved on the output shaft of the motor two.

[0007] As a further improvement of this utility model, an electric push rod is provided inside the slide cylinder, and the telescopic end of the electric push rod is connected and fixed to the slide column; a semi-tooth ring is provided inside the guide rail, and a motor is provided inside the slide table. A gear is fixedly sleeved on the lower end of the output shaft of the motor, and the gear meshes with the semi-tooth ring.

[0008] As a further improvement of this utility model, a grinding table is rotatably mounted on the upper surface of the frame. Multiple positioning holes are provided on the grinding table, and positioning pins are inserted into some of the positioning holes. A motor is mounted on the upper side inside the frame, and the output shaft of the motor is fixed to the grinding table by a coupling.

[0009] As a further improvement of this utility model, the lower surface of the frame is provided with multiple support legs, the front side of the frame is provided with symmetrically distributed door panels, and the side of the frame is provided with a control box. The electric push rod, motor one, motor two, motor three, motor four and motor five are all electrically connected to the control box.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, the control box regulates the operation of motor one, causing the output shaft of motor one to drive the grinding table connected to it to rotate, thereby adjusting the placement of the denture through the rotation of the grinding table.

[0012] Secondly, the control box regulates the operation of the motor and electric push rod, causing the slide to move the grinding head in an arc around the denture, adjusting the horizontal position of the grinding head. This, in turn, causes the slide column to move the grinding head up or down, allowing adjustment of the horizontal and vertical positions of the grinding head.

[0013] Third, the control box regulates the operation of the motor, causing the drive column to rotate through the slide groove, thereby causing the drive plate to rotate, which in turn causes the grinding head to rotate downwards or upwards, thus adjusting the tilt angle of the grinding head.

[0014] Fourth, by adjusting the horizontal position, vertical position, tilt angle, and distance from the denture of the grinding head, the denture to be ground can be ground quickly and stably with precision. Attached Figure Description

[0025] like Figure 2 , 3 As shown, the drive mechanism includes an adjusting screw 309 rotatably mounted inside the lower side of the rotating seat 301. A drive seat 307 is threadedly connected to the outer side of the adjusting screw 309. Drive columns are provided on both sides of the drive seat 307. Symmetrically distributed drive plates 308 are fixedly sleeved on the outer arc surface of the rotating shaft 302. A sliding groove on the lower side of the drive plate 308 is slidably connected to the adjacent drive columns. A motor 310 is located at the rear side of the rotating seat 301. The output shaft of the motor 310 is connected to the adjusting screw 309 via a coupling. The device is fixed; an adjusting screw 304 is rotatably installed inside the sliding cylinder 303, and the adjusting screw 304 is threadedly connected to the sliding rod 306.
