[0032] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see the attached Figure 1-3 The multi-purpose fixture for denture processing of the present invention includes a fixture base 100, and a pressure ring unit 200 or a screw fastener 300 detachably connected to the fixture base 100. The fixture base 100 is used for preliminary clamping and limiting the position of disc-shaped processing materials (e.g., titanium discs), block-shaped processing materials (e.g., glass ceramics), or column-shaped processing materials (e.g., titanium columns); the pressure ring unit 200 is used to fully clamp and limit the position of disc-shaped processing materials; and the screw fastener 300 is used to fully clamp and limit the position of block-shaped or column-shaped processing materials.

[0035] Please see the attached Figure 1 The pressure ring unit 200 includes a pressure ring 210 and a pressure ring fastener (not shown) that passes through the pressure ring 210 and connects to the fixture base 100. Preferably, the pressure ring fastener is a set screw. When clamping a disc-shaped workpiece (such as a titanium disc), after pressing the pressure ring 210 against one side of the titanium disc, the pressure ring fastener is simply passed through the pressure ring 210 and connected to the fixture base 100 to achieve clamping and limiting of the titanium disc.

[0036] During the denture processing process, different fixtures can be selected for clamping and positioning according to the different processing materials; for example, the fixture base 100 and the pressure ring unit 200 can be used in combination to clamp and position the disc-shaped processing materials; or the fixture base 100 and the screw fastener 300 can be used in combination to clamp and position the block-shaped processing materials or the columnar processing materials; by combining the same fixture base 100 with different detachable fasteners to achieve clamping of different processing materials, it can not only effectively be compatible with the positioning and installation of processing materials with different structures, improve the versatility of the fixture, thereby reducing the cost of fixture consumables and saving production costs, but also the universal fixture base 100 structure can effectively facilitate the management of the fixture and reduce the difficulty of fixture management.

[0037] Please refer to the attached Figure 4 The fixture base 100 is provided with a first mounting structure 110 that cooperates with the pressure ring unit 200 to complete the clamping and positioning of disc-shaped processing materials; and a second mounting structure 120 that cooperates with the screw fastener 300 to complete the clamping and positioning of block-shaped processing materials or columnar processing materials. By selecting any mounting structure to cooperate with the corresponding fastening structure, the clamping and positioning of the corresponding structural processing materials can be achieved, while meeting the clamping and positioning requirements for processing materials of different structures. Preferably, the second mounting structure 120 is set at the bottom of the first mounting structure 110, which can further effectively optimize the design layout of the fixture base 100, reduce the volume and weight of the fixture base 100, thereby achieving the purpose of reducing the overall volume and weight of the fixture, and further effectively reducing the cost of fixture consumables.

[0038] Please see the attached Figure 4 In some embodiments, the first mounting structure 110 includes a semicircular groove 111 opened on the fixture base 100 for preliminary clamping and limiting the disc-shaped processing material, and a first fastening connection hole 112 arranged on the semicircular groove 111; preferably, the first fastening connection hole 112 is a threaded hole structure, which is symmetrically arranged on both sides of the fixture base 100, and in order to have both the stability and effect of the fixture clamping, it is further preferred that the number of the first fastening connection holes 112 is 2-4.

[0039] Furthermore, the semicircular groove 111 includes a semicircular groove mounting portion 1111 for preliminarily limiting the disc-shaped processing material, and a protrusion limiting portion 1112 protruding from the side of the semicircular groove mounting portion 1111 away from the pressure ring unit 200 and cooperating with the pressure ring unit 200 to completely limit the disc-shaped processing material; preferably, the protrusion limiting portion 1112 is a protrusion evenly and spaced along the semicircular groove mounting portion 1111, or a convex eaves arranged along the edge of the semicircular groove mounting portion 1111; the specific selection and design can be made according to actual needs, and it is mainly sufficient to achieve movement restriction on one side of the disc-shaped processing material. When the titanium disk is clamped, it is placed in the semicircular groove 111. At this time, the semicircular groove mounting portion 1111 in the semicircular groove 111 can initially limit its radial position, and the protrusion limiting portion 1112 in the semicircular groove 111 can initially limit its axial position; after continuing to use the pressure ring unit 200 to limit the other side of the titanium disk, the titanium disk can be completely clamped and limited.

[0040] Furthermore, the angle between the two side endpoints of the semicircular groove 111 and the center of the circle is less than 180°, that is, the semicircular groove 111 is at least a semicircular structure, which can effectively limit the radial direction of the disc-shaped processing material to prevent the disc-shaped processing material from shifting during the processing; preferably, the semicircular groove 111 is a three-quarter circular groove structure, which can effectively limit the disc-shaped processing material without interfering with the processing of the disc-shaped processing material.

[0041] Please see the attached Figure 4 In some embodiments, the first mounting structure 110 also includes a pressure ring limiting semicircular groove 113 provided on the fixture base 100 for limiting the pressure ring unit 200; preferably, the pressure ring limiting semicircular groove 113 is a sunken groove structure opened on the fixture base 100, which can effectively reduce the volume and weight of the fixture base 100 on the basis of limiting the pressure ring 210 unit 200, so as to reduce the overall volume and weight of the processing fixture, thereby further reducing the cost of the processing fixture.

[0042] In some embodiments, the first mounting structure 110 may further include a pressure ring limiting convex eaves (not shown in the figure) convexly provided on the clamp base 100 for limiting the pressure ring unit 200; the specific selection and design can be made according to actual needs, and the main function is to limit the pressure ring unit 200.

[0043] Please see the attached Figure 4 In some embodiments, the second mounting structure 120 includes a rectangular groove 121 arranged at the bottom of the first mounting structure 110, and a second fastening connection hole 122 arranged at the bottom of the rectangular groove 121; the screw fastener 300 can be directly connected to the block processing material or the columnar processing material by passing through the second fastening connection hole 122, thereby achieving complete limitation of the block processing material or the columnar processing material.

[0044] Please see the attached Figure 3 Furthermore, when the second mounting structure 120 is used in conjunction with the screw fastener 300, the multi-purpose fixture for denture processing also includes a raw material limiting block 400 for realizing detachable installation of block-shaped processing materials or column-shaped processing materials; further, the raw material limiting block 400 includes a limiting block body 410, and a plurality of clamping holes 420 arranged side by side on the limiting block body 410. The raw material limiting block 400 is connected to the screw fastener 300, and the bottom of the block-shaped processing material or column-shaped processing material is designed as a clamping groove structure. As long as the block-shaped processing material or column-shaped processing material is inserted into the clamping hole 420, the block-shaped processing material or column-shaped processing material can be completely limited. Compared with the method of connecting a single processing material with the screw fastener 300, the plug-in connection method can effectively improve the efficiency of processing material replacement, reduce the difficulty of processing material replacement, and thus effectively improve the production efficiency of processing materials.

[0045] Please see the attached Figure 1-3 In some embodiments, the multi-purpose fixture for denture processing further includes a component mounting seat 500 provided on the side of the fixture base 100, which is used for installing and connecting the entire fixture with external equipment; when the fixture is changed, the entire fixture can be installed by connecting the component mounting seat 500 with the external equipment.

[0046] It can be seen from the technical solutions of the above embodiments that the utility model provides a multi-purpose fixture for denture processing, which can not only effectively accommodate the positioning and installation of processing materials with different structures, improve the versatility of the fixture, thereby reducing the cost of fixture consumables and saving production costs, but also the universal fixture structure can effectively facilitate the management of the fixture and reduce the difficulty of fixture management.
