As shown in fig. 1 to 3, a layout fixture shown in an embodiment includes: mount 30, clamp body 10, and pressure plate 20. The mounting seat 30 is used for assembling the clamp body 10 and the pressure plate 20 on the denture processing equipment, and the clamp body 10 and the pressure plate 20 are matched for clamping and fixing the zirconia ceramic block 40.

The mounting seat 30 is connected to the jig body 10. Preferably, the mounting seat 30 is integrally formed with the jig body 10, which not only facilitates manufacturing, but also improves the overall structural strength of the resulting typesetting jig. Of course, in other embodiments, the mounting seat 30 and the fixture body 10 may be detachably connected, so that the mounting seat 30 is fixed to the base and is stationary, and different fixture bodies 10 may be flexibly replaced according to different product sizes, thereby increasing the application range of the composition fixture.

Referring to fig. 3, the mounting base 30 is provided with a mounting through hole 31. During installation, the installation base 30 is placed on the machine base, the installation through hole 31 is aligned with a threaded hole preset on the machine base, and then a screw penetrates through the installation through hole 31 and is screwed in the threaded hole. Further, in order to improve the connection strength, four mounting through holes 31 arranged in a rectangular shape are formed in the mounting base 30, so that a multipoint fixing and mounting structure can be formed.

During machining, the cutter is fed to the surface of the contact zirconia ceramic block 40, and rigid contact milling or drilling machining is carried out, wherein the clamp body 10 is subjected to larger rigid extrusion force of the cutter. In order to avoid the fracture of the clamp body 10 and the mounting seat 30, the mounting seat 30 is in arc-shaped transition connection with the clamp body 10. Therefore, the design of the arc-shaped transition connecting part can effectively prevent stress transition concentration, thereby effectively solving the problems.

With reference to fig. 1 and fig. 2, in an embodiment, the fixture body 10 is provided with a bearing portion 11 and a notch portion 12, the zirconia ceramic block 40 can be disposed in the bearing portion 11 and partially extend into the notch portion 12, and the distribution area of the notch portion 12 accounts for 1/3 to 1/2 of the total area of the fixture body 10; the pressing plate 20 is disposed on the fixture body 10 and can press the zirconia ceramic block 40 against the bearing part 11 to be fixed.

The embodiment of the invention has the following beneficial effects: the typesetting fixture is applied to false tooth processing and manufacturing, and can clamp and fix the zirconia porcelain block 40 (standard) so as to conveniently typeset, process and shape the crown and bridge products. Specifically, the zirconia ceramic block 40 is placed on the bearing portion 11 of the jig body 10 at the time of machining, and then the pressing plate 20 is mounted on the jig body 10, so that the zirconia ceramic block 40 can be held and fixed between the pressing plate 20 and the bearing portion 11 at most all times. Because the notch part 12 is designed and manufactured on the clamp body 10, the clamping contact area between the clamp body 10 and the zirconia ceramic block 40 is reduced, so that the part of the zirconia ceramic block 40 extending into the notch part 12 can be used for processing and forming a crown bridge product, namely, compared with the prior art, more zirconia ceramic block 40 materials are involved in processing and manufacturing the product, and the utilization rate of raw materials is greatly improved; in addition, since the distribution area of the notch portions 12 occupies 1/3 to 1/2 of the jig body 10, that is, the portion of the jig body 10 having 2/3 to 1/2 can be used for clamping and fixing the zirconia ceramic block 40, the zirconia ceramic block 40 can be firmly and reliably clamped; on this basis, because the existence of breach portion 12 for the cutter has more removal spaces when processing to zirconia porcelain piece 40, realizes that the cutter does not occupy the material and can remove outside the material promptly, can reduce the probability that the cutter collided the anchor clamps when processing special model product to a certain extent, thereby prevents the cutter fracture.

Referring to fig. 1 and 2, in an embodiment, the clamp body 10 is a stainless steel plate body with a semi-circular structure, it can be understood that the clamp body 10 is a complete circular plate body with portions 2/3-1/2 cut out, and correspondingly, the remaining portions 1/3-1/2 of the circular plate body form the notch 12. The notch portion 12 is formed by spacing two free ends of the clamp body 10, and the notch portion 12 is communicated with the annular cavity of the clamp body 10. The bearing part 11 is an arc-shaped step concavely arranged along the inner annular wall of the clamp body 10, and the size of the arc-shaped step needs to be matched with the overall size of the zirconia ceramic block 40 so as to ensure that the clamping is firm and is not easy to loosen.

In a more preferred embodiment, the clamp body 10 is a 2/3 portion of a full circular plate; accordingly, the notch portion 12 occupies 1/3 portion of the complete annular plate body. At the moment, the round cake-shaped zirconia ceramic block 40 is clamped and embedded in the arc-shaped step and limited by the side wall of the arc-shaped step, so that the moving and rotating freedom degrees of the zirconia ceramic block 40 in the X and Y axis directions can be effectively limited. Then, the pressing plate 20 is installed, so that the moving and rotating freedom degree of the zirconia ceramic block 40 in the Z-axis direction can be further limited, and the zirconia ceramic block 40 is finally firmly clamped and fixed.

Of course, in other embodiments, the pressing plate 20 and the clamp body 10 can be fixed by other installation methods well known in the art, such as snap connection, magnetic attraction connection, riveting, etc.

Further, in an embodiment, an arc-shaped boss is further disposed on a side surface of the pressing plate 20 facing the zirconia ceramic block 40, and the arc-shaped boss can be embedded in and pressed against an arc-shaped step on the zirconia ceramic block 40. Therefore, the arc-shaped boss is pressed on the upper surface of the zirconia ceramic block 40, so that the pressing plate 20 can be matched with the arc-shaped step to further fix the zirconia ceramic block 40.

Referring to fig. 2, after the crown and bridge product is processed, in order to be easily removed from the typesetting jig, the jig body 10 is further provided with a through groove 13 penetrating through the thickness direction thereof. Therefore, the fingers or tools of the workers can penetrate through the through grooves 13 to eject the product from the clamp body 10, and the problem that the zirconia ceramic blocks 40 are assembled with the arc-shaped steps too tightly to be separated conveniently is effectively solved.

Further preferably, the through slots 13 are at least two and are spaced apart from each other along the inner annular wall of the clamp body 10. So, can follow arbitrary logical groove 13 and carry out the ejecting operation of product, the flexible operation is convenient, does benefit to and promotes work efficiency.
