Description

Technical Field

[0001] The utility model relates to the technical field of denture processing, in particular to a grinding and positioning device for a denture implant base. Background Technique

[0002] With the continuous development of oral medicine technology, edentulous implant-fixed dentures play an increasingly important role in repairing tooth loss. The successful installation of edentulous implant-fixed dentures depends on the precise production of implant bases, and the grinding link has a key impact on the shape, size and surface accuracy of the bases.

[0003] A grinding and positioning device for a denture implant base is disclosed in the patent with the publication number CN218082031U, which includes a placement seat. The lower end of the placement seat is installed with a spherical block through a support rod. The spherical block is rotatably connected to the inner side wall of a movable groove opened on the side wall of a fixed seat. A limiting seat is sleeved on the outer side wall of the spherical block, and the limiting seat is fixedly installed on the upper side wall of the fixed seat. The upper side wall of the fixed seat is symmetrically installed with lead screws, and the opposite ends of the lead screws are fixedly connected with clamping rods. When grinding the denture implant base, first fix the denture to the placement seat, and then the placement seat can be rotated. The placement seat drives the spherical block to adjust the angle. After the adjustment is completed, rotate the two lead screws, and the lead screws drive the clamping rods to squeeze the spherical block, so as to realize the position locking of the spherical block. Although the cooperation of the spherical block and the clamping rod can adjust the angle of the placement seat in any direction, the method of preventing the spherical block from rotating by squeezing the spherical block with the clamping rod is relatively unstable. After the device is used for a long time, due to the long-term friction between the clamping rod and the spherical block, the contact surface between the spherical block and the clamping rod becomes smooth, so that the friction coefficient of the contact surface between the clamping rod and the spherical block becomes smaller, resulting in the clamping rod being difficult to limit the spherical block. Once the spherical block rotates, the angle of the placement seat will deflect, which may cause the angle of the staff to grind the denture implant base to deflect, thus affecting the grinding accuracy of the denture implant base and further affecting the quality of the denture implant base.

[0004] Therefore, it is necessary to provide a new grinding and positioning device for a denture implant base to solve the above technical problems. Content of the Utility Model

[0025] In the specific implementation process, as shown in Figure 1 —7, it includes: a base 1, a rotating mechanism 2 is rotatably installed at the top end of the base 1, a first receiving plate 3 and a second receiving plate 4 which are oppositely arranged are integrally installed on the upper end surface of the rotating mechanism 2, an angle adjustment mechanism 6 is rotatably connected between the first receiving plate 3 and the second receiving plate 4, and a clamping assembly 8 is movably installed in the angle adjustment mechanism 6;

[0026] The rotating mechanism 2 includes a first turntable 201 which is rotatably connected to the base 1. An integrally formed first ratchet 202 is connected to the upper end surface of the base 1. A first slider 205 is rotatably connected to the bottom end of the first turntable 201. The first slider 205 meshes with the first ratchet 202. An integrally formed first knob 204 is connected to the top end of the first slider 205. The first knob 204 passes through the upper end surface of the first turntable 201. Above the first ratchet 202, a second ratchet 203 is connected by a first connecting rod 207. The second ratchet 203 is rotatably connected within the first turntable 201. A first chute 206 is formed within the first turntable 201. A telescopic assembly 5 is connected to the side wall of the first chute 206.

[0027] It should be noted that a ring-shaped chute with a "convex" cross-section is formed at the top end of the base 1. A movable block matching the ring-shaped chute is fixedly connected to the bottom end of the disc. While the turntable rotates along the ring-shaped chute, due to the cooperation between the movable block and the ring-shaped chute, the turntable can also be limited to prevent it from detaching from the base 1.

[0028] The telescopic assembly 5 includes a second slider 501 and a first spring 502. A second chute 503 is formed on one side of the second ratchet 203. The first spring 502 is welded to the side wall of the second chute 503. One end of the first spring 502 is welded to the second slider 501. One end of the second slider 501 meshes with the second ratchet 203.

[0029] The angle adjustment mechanism 6 includes a bearing platform 601. One end of the bearing platform 601 is rotatably connected to the second receiving plate 4. An integrally formed rotating rod 603 is connected to the other end of the bearing platform 601. The other end of the rotating rod 603 passes through the first receiving plate 3. An integrally formed second knob 602 is connected to the other end of the rotating rod 603. A limiting assembly 7 for limiting the knob is inserted into the second knob 602.

[0030] The limiting assembly 7 includes a second turntable 701 which is connected to the end of the second knob 602 away from the rotating rod 603. A pull rod 702 is fixedly connected to the side of the second turntable 701 away from the first receiving plate 3. A second connecting rod 703 is fixedly connected to the side of the second turntable 701 adjacent to the first receiving plate 3. A third chute 706 is formed within the second knob 602. The second connecting rod 703 is inserted into the third chute 706. A second spring 704 is nested outside the second connecting rod 703. A third slider 705 is also fixedly connected to the other side of the second connecting rod 703. A plurality of slots 707 matching the third slider 705 are formed on the side of the first receiving plate 3 adjacent to the second turntable 701. The third slider 705 is inserted into the slots 707.

[0031] It should be noted that multiple slots 707 are arranged in a circle. When the angle of the carrier 601 needs to be adjusted, first pull the pull rod 702. The pull rod 702 drives the second turntable 701, the second connecting rod 703 and the third slider 705 to slide along the third chute 706. At the same time, the third slider 705 is pulled out of the slot 707. When the user adjusts the carrier 601 to a more comfortable angle for grinding the denture implant base and then releases the pull rod 702, at this time, under the reset action of the second spring 704, the second connecting rod 703 slides along the third chute 706, and at the same time, the third slider 705 is inserted back into the slot 707 to complete the limit of the knob. If a higher-precision angle adjustment is required, n third chutes 706 can be opened in the knob, where n is a positive integer, and n second connecting rods 703 are connected to the side of the second turntable 701 adjacent to the first receiving plate 3. One ends of the n second connecting rods 703 are respectively connected to the third sliders 705, and the number of the n third sliders 705 is not equal to the number of the slots 707. Suppose the number of the slots 707 is (n±k) and k is an odd number. Then every time the second knob 602 is rotated (360 / (n*(n±k)))°, one of the third sliders 705 is inserted into the slot 707, so as to achieve a more precise adjustment of the angle. For example, when n is 5 and k is 4, the number of the slots 707 is 9 at this time. Rotate the second turntable 701 to insert one of the third sliders 705 into the slot 707. At this time, every time the second knob is rotated 8°, the other third sliders 705 can be inserted into one of the slots 707, so as to limit the second knob 602.

[0032] The clamping assembly 8 includes a double-headed threaded rod 801. A groove 802 is opened in the carrier 601, and the double-headed threaded rod 801 is inserted into the groove 802. One end of the double-headed threaded rod 801 is movably connected to the side wall of the groove 802. The other end of the double-headed threaded rod 801 passes through the carrier 601, and a third knob 803 is fixedly connected to the other end of the double-headed threaded rod 801. Both ends of the double-headed threaded rod 801 are threadedly connected with movable plates 804;

[0033] It should be noted that threads are opened at both ends of the double-headed threaded rod 801, and the directions of the threads at both ends of the double-headed threaded rod 801 are opposite. When the third knob 803 is rotated, the double-headed threaded rod 801 drives the two movable plates 804 to move towards or away from each other.

[0034] The first ratchet 202 is located above the second ratchet 203, and the tooth directions of the first ratchet 202 and the second ratchet 203 are opposite;

[0035] It should be noted that since the ratchet 202 is limited by the slider 205 and the knob 204, this can be manually controlled. The limit of the ratchet 203 is controlled by the slider 501 and the spring 502, so as to control the rotation of the turntable 201 in a single direction. When it rotates to an appropriate angle, by rotating the knob 204, the slider 205 is engaged with the ratchet 202, so as to simultaneously limit the forward and reverse rotations of the turntable 201.

[0036] When the denture implant base needs to be polished, first place the denture on the bearing platform 601, then rotate the knob 803. The knob 803 drives a plurality of movable plates 804 to move towards each other, and the plurality of movable plates 804 clamp the denture. Then pull the pull rod 702 and rotate the turntable 701. After adjusting the bearing platform 601 to a comfortable angle for the user, release the pull rod 702. At this time, under the action of the spring 704, the slider 705 is inserted into the slot 707, so as to limit the knob 803 and prevent the knob 803 from rotating during the polishing process. Then rotate the knob 204. The knob 204 drives the slider 205 to rotate around the knob 204, so that the ratchet 202 and the slider 205 are disengaged, thus releasing the limit of the ratchet 202 on the slider 205. At the same time, since the tooth direction of the ratchet 203 is opposite to that of the ratchet 202, and the ratchet 203 can only rotate in a single forward direction under the action of the slider 501 and the spring 502, the turntable 201 is rotated in a single forward direction. When it rotates to an angle where the user feels comfortable polishing the denture implant base, rotate the knob 204 in the reverse direction. The knob 204 drives the slider 205 to rotate in the reverse direction with the knob 204 as the axis, so that the slider 205 is engaged with the ratchet 202. The slider 205 and the ratchet 202 limit the forward rotation of the turntable 201, while the slider 501 and the ratchet 203 limit the reverse rotation of the turntable 201, so as to limit the rotation of the turntable 201 and prevent the change of the polishing angle caused by the rotation of the turntable 201 during the polishing process, thereby affecting the polishing accuracy of the denture implant base.

[0037] The working principle provided by the present utility model is as follows: Rotate the first knob 204, and the first knob 204 drives the first slider 205 to rotate, so that the first slider 205 disengages from the first ratchet wheel 202. Then rotate the first turntable 201, and the first turntable 201 rotates in a single direction around the first ratchet wheel 202. If the first turntable 201 is rotated in the reverse direction, since the second ratchet wheel 203 is fixedly installed above the first ratchet wheel 202, the tooth directions of the second ratchet wheel 203 and the first ratchet wheel 202 are opposite, and a second chute 503 is formed in the first turntable 201. A first spring 502 is welded to the side wall of the second chute 503, and a second slider 501 is welded to one end of the first spring 502. The second slider 501 meshes with the second ratchet wheel 203. With the cooperation of the second ratchet wheel 203 and the second slider 501, the first turntable 201 is prevented from rotating, thereby realizing the limitation of the forward and reverse rotation of the first turntable 201.

[0038] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated herein.

[0039] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
