Description

Technical Field

[0001] This utility model belongs to the field of dental medical device technology, and in particular relates to a conversion clamp for denture processing. Background Technology

[0002] Currently, the dental prosthesis industry mainly uses CNC milling machines for processing. For example, when using zirconia as the material, the clamps inside the CNC milling machine hold a disc-shaped zirconia material that matches the clamps. Then, the cutting tools inside the CNC milling machine perform subtraction processing on the zirconia material to complete the prosthesis forming. That is, most existing clamps use semi-circular clamping slots to hold the material, so the material can only be adapted to a disc-shaped material that matches it. However, the material in the clamping part does not participate in the prosthesis forming; it is only for the convenience of clamping. As a result, the remaining material after the prosthesis is formed can only be discarded, causing a lot of material waste and increasing production costs.

[0003] Therefore, there is an urgent need to design a conversion jig for denture processing to solve the problem of material waste mentioned above. Utility Model Content

[0004] To address the technical problem of material waste in the processing mentioned in the background art, a conversion jig for denture processing is provided to solve the above-mentioned problem.

[0005] To achieve the above objectives, the specific technical solution of the conversion jig for denture processing of this utility model is as follows:

[0006] A conversion jig for denture processing includes an arc-shaped block fixedly connected to a clamping groove of the jig, and a positioning groove fixedly connected to one end of the arc-shaped block away from the clamping groove, the positioning groove being fixedly connected to the processing material.

[0007] Furthermore, the arc-shaped block includes an arc-shaped end and a straight end, with the arc-shaped end fixedly connected to the clamping groove and the straight end fixedly connected to the positioning groove.

[0008] Furthermore, an angle positioning block is fixedly connected to the arc-shaped end, and the angle positioning block abuts against the edge of the clamping groove to limit the angle of the arc-shaped block.

[0009] Furthermore, a weight-reducing groove is provided on the curved end.

[0010] Furthermore, weight-reducing holes are provided on the arc-shaped block.

[0011] Furthermore, the weight-reducing holes are symmetrically arranged on the arc-shaped block.

[0012] Furthermore, the weight-reducing holes are arranged in a circular array with the midpoint of the chord on the arc-shaped block as the center.

[0013] Furthermore, it also includes an arc-shaped machining material, which is bonded to the positioning groove.

[0014] Furthermore, the positioning groove is a rectangular groove, and a connecting protrusion matching the rectangular groove is provided on the arc-shaped machined material. The connecting protrusion is bonded to the rectangular groove.

[0015] Furthermore, the positioning groove is a dovetail groove, and the arc-shaped machined material has a connecting protrusion that matches the dovetail groove. After the connecting protrusion is mortised and tenoned with the dovetail groove, it is glued into the dovetail groove.

[0016] The conversion jig for denture processing of this utility model has the following advantages:

[0017] This invention connects the processing material and the fixture by means of an arc-shaped block, which not only improves the functionality and stability of the fixture, but also increases the utilization rate of the processing material, reduces production costs, and thus improves processing efficiency and processing accuracy.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0024] The following is a reference to the appendix. Figure 1 To be continued Figure 3 This invention describes a conversion jig for denture processing.

[0025] Most existing clamps 4 use semi-circular clamping slots 401 to hold the material, so the material to be processed can only be adapted to a matching disc-shaped material. However, the material to be processed in the clamping part does not participate in the denture forming process; it is only for the convenience of clamping 4. As a result, the remaining material after the denture is formed can only be discarded, causing a large amount of material waste and increasing production costs.

[0026] Therefore, this utility model provides a conversion jig for denture processing, such as Figures 1-3 As shown, the fixture includes an arc-shaped block 1 fixedly connected to the clamping groove 401 of the fixture 4. A positioning groove 2 is fixedly connected to one end of the arc-shaped block 1 away from the clamping groove 401. The positioning groove 2 is fixedly connected to the processing material. Specifically, by replacing the processing material located in the clamping part with the arc-shaped block 1, the cost of the processing material is reduced. Moreover, the arc-shaped block 1 can be reused, further reducing the waste of processing material and reducing production costs.

[0027] As a preferred option, such as Figure 1 and Figure 3 As shown, the arc-shaped block 1 includes an arc-shaped end 101 and a straight end 102. The arc-shaped end 101 is fixedly connected to the clamping groove 401, and the straight end 102 is fixedly connected to the positioning groove 2. Specifically, the arc-shaped end 101 can better fit the existing semi-circular clamping groove 401, retaining the stability of the connection with the clamping groove 401, and the straight end 102 provides a flat and regular area, which is convenient for the subsequent installation of the positioning groove 2 and the processing material.

[0028] As a preferred option, such as Figure 1 and Figure 3 As shown, an angle positioning block 1011 is fixedly connected to the arc-shaped end 101. The angle positioning block 1011 abuts against the edge of the clamping groove 401 to limit the angle of the arc-shaped block 1. Specifically, the angle positioning block 1011 can accurately limit the installation angle of the arc-shaped block 1 relative to the clamping groove 401, avoiding inaccurate material position due to angle deviation. Furthermore, the connection stability between the arc-shaped block 1 and the clamping groove 401 is further enhanced by the angle positioning block 1011 abutting against the edge of the clamping groove 401.

[0029] As a preferred option, such as Figure 1 As shown, a weight-reducing groove 1012 is provided on the arc-shaped end 101, thereby effectively reducing the overall weight of the arc-shaped block 1, reducing the load on the clamp 4, and reducing the mass inertia of the clamp 4 during rotation, thus increasing the stability and accuracy of clamping. Optionally, such as... Figure 1 As shown, the weight-reducing groove 1012 can be formed on the arc-shaped plane near the clamping groove 401 on the arc-shaped end 101, or it can be formed on the two opposite end faces of the arc-shaped plane. Specifically, the weight-reducing groove 1012 can be formed at any position that does not affect the connection strength between the clamping groove 401 and the arc-shaped block 1.

[0030] Preferably, the weight-reducing grooves 1012 are symmetrically arranged on the arc-shaped end 101 to ensure the balance and stability of the fixture 4 during the processing.

[0031] Preferably, the bow-shaped block 1 is provided with a weight-reducing hole 103, which further reduces the weight of the bow-shaped block 1, thereby reducing the load on the clamp 4 and reducing the mass inertia when the clamp 4 rotates.

[0032] Preferably, the weight-reducing holes 103 are symmetrically arranged on the bow-shaped block 1, so that the bow-shaped block 1 is subjected to more uniform force, ensuring the balance and stability of the fixture 4 during the processing, reducing the possibility of vibration or displacement, and avoiding structural deformation or processing errors caused by uneven weight distribution.

[0033] In another preferred embodiment, the weight-reducing holes 103 are arranged in a circular array with the midpoint of the chord on the bow-shaped block 1 as the center, so that the bow-shaped block 1 is subjected to more uniform force, and at the same time, it is easier to maintain the high strength and stability of the structure, further ensuring the balance and stability of the fixture 4 during the processing, reducing the possibility of vibration or displacement, and avoiding structural deformation or processing errors caused by uneven weight distribution.

[0034] As a preferred option, such as Figure 2 and Figure 3 As shown, it also includes an arc-shaped processing material 3, which is bonded to the positioning groove 2. The arc-shaped processing material 3 can better adapt to the structure of the positioning groove 2, improve the utilization rate of processing materials, and reduce material waste in traditional disc-shaped materials.

[0035] As a preferred option, such as Figure 3As shown, the positioning groove 2 is a rectangular groove, and the bow-shaped processing material 3 is provided with a connecting protrusion 301 that matches the rectangular groove. The connecting protrusion 301 is bonded to the rectangular groove. Specifically, the matching design of the rectangular groove and the connecting protrusion 301 can achieve precise alignment, so that the bow-shaped processing material 3 and the bow-shaped block 1 form a moving whole, reducing the scrap rate caused by positional offset, ensuring the stability of the processing material installation, and facilitating personnel installation and bonding.

[0036] In another preferred embodiment, the positioning groove 2 is a dovetail groove, and the arc-shaped processing material 3 is provided with a connecting protrusion 301 that matches the dovetail groove. After the connecting protrusion 301 is mortised and tenoned with the dovetail groove, it is bonded to the dovetail groove. Specifically, the design of the dovetail groove has higher connection strength and stability, and can withstand greater processing force. On the basis of bonding, the mortise and tenon connection reduces the scrap rate caused by loosening or falling off of the arc-shaped processing material 3, and also facilitates personnel installation and bonding.

[0037] As a further preferred embodiment, this utility model adopts an integral molding structure to ensure zero-error connection between the positioning groove 2 and the bow-shaped block 1, thereby ensuring that the clamped bow-shaped processing material 3 is accurately located on the ideal processing plane.

[0038] This utility model connects the processing material and the fixture 4 through the bow-shaped block 1, which not only improves the functionality and stability of the fixture 4, but also increases the utilization rate of the processing material, reduces production costs, and thus improves processing efficiency and processing accuracy.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
