[0033] Combine the following Figure 1 to Figure 2 It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0034] Figure 1 It is a schematic diagram of the overall structure of a fixture for processing zirconia ceramic blocks provided by an embodiment of the utility model; Figure 2 It is a schematic diagram of the overall structure of the limit assembly provided in an embodiment of the utility model.

[0035] See also Figure 1 and Figure 2The first aspect of the utility model provides a clamp for processing zirconia ceramic blocks, which is hereinafter referred to as a clamp. The clamp includes a clamping component 100 and a limiting component 200. The clamping component 100 and the limiting component 200 are both arranged on the device body, and the limiting component 200 is located below the clamping component 100. The clamping component 100 is used to clamp the workpiece to be processed. The limiting component 200 is provided with a limiting groove 221. The limiting groove 221 and the workpiece to be processed are abutted against each other. The limiting component 200 is suitable for adjusting the position of the workpiece to be processed so that the workpiece to be processed and the clamping component 100 remain coaxial.

[0036] See also Figure 1 and Figure 2 It can be understood that, during use, the fixture for processing zirconia ceramic blocks provided by the embodiment of the utility model can first place the workpiece to be processed on the limiting groove 221 of the limiting component 200, and adjust the position of the workpiece to be processed by the limiting component 200. When the workpiece to be processed is coaxial with the clamping component 100, the workpiece to be processed is fixed by the clamping component 100, so that the workpiece to be processed can maintain good coaxiality with the clamping component 100 during the processing, thereby improving the uniformity of the product after molding. Compared with the prior art, the fixture for processing zirconia ceramic blocks provided by the embodiment of the utility model limits the workpiece to be processed by the limiting groove 221 of the limiting component 200, avoids the problem of inaccurate product positioning due to manual placement, improves the uniformity of the product after processing, reduces the deviation of the product after processing, and improves the processing efficiency of mass production of zirconia ceramic blocks.

[0037] Continue reading Figure 1 and Figure 2 In an optional embodiment of the utility model, the limiting assembly 200 includes a base 210, a limiting member 220 and a positioning member 230, wherein the base 210 is provided with a through hole, the limiting member 220 is provided on a side of the base 210 facing the workpiece to be processed, the limiting groove 221 is provided at one end of the limiting member 220 facing the workpiece to be processed, and the limiting member 220 is provided with a waist-shaped hole 222 at one end facing the base 210, and the waist-shaped hole 222 corresponds to the aforementioned through hole. During the assembly process, the through hole and the waist-shaped hole 222 can be first assembled. 22 is aligned, and then the positioning member 230 is passed through the through hole and the waist-shaped hole 222 in sequence, or the positioning member 230 is passed through the waist-shaped hole 222 and the through hole in sequence, and then the positioning member 230 is tightened to fix the position of the limit member 220. In an optional embodiment of the utility model, the positioning member 230 can be obtained by a combination of fasteners such as bolts, screws and nuts, or it can only include one bolt. In this case, a corresponding thread can be set on the through hole. Specifically, it can be adaptively set according to actual conditions.

[0038] See also Figure 1 and Figure 2It can be understood that the clamp for processing zirconia ceramic blocks provided by the embodiment of the utility model can adjust the position of the limit member 220 relative to the base 210 by adjusting the position of the positioning member 230 relative to the waist-shaped hole 222. In this way, in the process of adjusting the limit member 220, the workpiece to be processed abutting therewith will move with the movement of the limit member 220, thereby realizing the adjustment of the coaxiality between the workpiece to be processed and the clamping assembly 100. After the coaxiality adjustment is completed, the relative position between the limit member 220 and the workpiece to be processed and the clamping assembly 100 can be fixed by tightening the positioning member 230, so that the workpiece to be processed always remains coaxial with the clamping assembly 100 during the processing process.

[0039] Continue reading Figure 1 and Figure 2 In an optional embodiment of the utility model, the limiting component 200 also includes a limiting column 240, which is arranged on the groove wall of the limiting groove 221. It can be understood that when the limiting column 240 abuts against the workpiece to be processed, since the side wall of the limiting column 240 is an arc surface, the contact area between the limiting column 240 and the workpiece to be processed is relatively small, and it is a line contact mode, compared with the groove wall of the limiting groove 221. In this way, the contact area between the workpiece to be processed and the abutting surface (the surface abutting against the workpiece to be processed, that is, the groove wall of the limiting groove 221 or the side wall of the limiting column 240) can be greatly reduced, and the wear between the workpiece to be processed and the abutting surface can be greatly reduced. In this way, in the process of using the limiting member 220, the influence of the limiting groove 221 on the processing accuracy of the workpiece to be processed can be reduced. In other words, the processing accuracy of the workpiece to be processed can be improved, and the identity of the processed product can be improved.

[0040] In an optional embodiment of the utility model, the limiting column 240 can be made of the same metal material as the limiting member 220, or plastic or other materials, and can be selected according to the actual situation. In some other optional embodiments of the utility model, the limiting column 240 can also be replaced by a device such as a rubber pad, so that the workpiece to be processed can be prevented from being hard-damaged when it abuts against the limiting groove 221, and the safety of the workpiece to be processed during the processing can be improved.

[0041] Continue reading Figure 1 and Figure 2 The limit assembly 200 also includes a support rod 250, which is passed through one end of the base 210 away from the limit member 220. The support rod 250 and the base 210 can be fixedly connected or movably connected. It can be understood that the length of the support rod 250 is longer than that of the base 210. In this way, when the limit assembly 200 is placed on a platform, the support rod 250 will abut against the platform, thereby supporting the base 210 to prevent the base 210 from tipping over during use.

[0042] Continue reading Figure 1 and Figure 2 In an optional embodiment of the utility model, the limiting groove 221 is a "V"-shaped groove, and the opening of the V-shaped groove faces the workpiece to be processed. It can be understood that the V-shaped groove is simple to make. During the adjustment process of the workpiece to be processed, the workpiece to be processed can be resisted and restricted from two sides, which can make the adjustment of the coaxiality between the workpiece to be processed and the clamping assembly 100 more convenient and easy. Compared with adjusting from one side, this can greatly improve the adjustment efficiency of the coaxiality.

[0043] Continue reading Figure 1 and Figure 2 In an optional embodiment of the utility model, the clamping assembly 100 includes a first clamping member 110 and a second clamping member 120, the first clamping member 110 abuts against one end of the workpiece to be processed, the second clamping member 120 abuts against the other end of the workpiece to be processed, and the first clamping member 110 and the second clamping member 120 are coaxially arranged. It can be understood that by limiting the workpiece to be processed from both ends of the workpiece to be processed by the first clamping member 110 and the second clamping member 120, the contact area between the workpiece to be processed and the clamping assembly 100 can be minimized under the premise of ensuring the stability of the workpiece to be processed. In addition, in such a positional relationship, the area of ​​the workpiece to be processed exposed to the outside is larger, which is conducive to the processing and position adjustment of the workpiece to be processed. In the case of setting the limit assembly 200, it can be convenient for the limit assembly 200 to adjust the position of the workpiece to be processed, and the adjustment efficiency of the coaxiality between the workpiece to be processed and the first clamping member 110 and the second clamping member 120 can be improved.

[0044] Continue reading Figure 1 and Figure 2 In an optional embodiment of the utility model, the clamping assembly 100 also includes a gasket 130, and the gasket 130 is arranged on at least one of the side of the first clamping member 110 facing the workpiece to be processed and the side of the second clamping member 120 facing the workpiece to be processed. It can be understood that by setting the gasket 130, the wear and hard damage of the workpiece to be processed during the contact process with the first clamping member 110 and the second clamping member 120 can be reduced, and the safety of the workpiece to be processed during the processing can be improved.

[0045] Continue reading Figure 1 and Figure 2 In an optional embodiment of the utility model, the limit assembly 200 is located between the first clamping member 110 and the second clamping member 120. It can be understood that with such a configuration, during the processing, when the first clamping member 110 and the second clamping member 120 clamp the workpiece from both ends at the same time, balance can be ensured to avoid the position change of the workpiece due to any one of the first clamping member 110 and the second clamping member 120 contacting the workpiece first. In this way, the installation process can be simplified and the installation efficiency can be improved.

[0046] Specifically, when the clamp provided by the embodiment of the utility model is in use, the limit assembly 200 is first moved to directly below the first clamping member 110 and the second clamping member 120, and then the positioning member 230 is loosened, and the position of the limit member 220 relative to the base 210, that is, the height of the limit member 220 is adjusted, so that the center of the zirconia ceramic block after the limit adjustment is exactly located on the central axis of the first clamping member 110 and the second clamping member 120, and the positioning member 230 is tightened, and then the first clamping member 110 and the second clamping member 120 are started to clamp the workpiece to be processed, and the installation of the zirconia ceramic block can be completed.

[0047] Continue reading Figure 1 and Figure 2 In an optional embodiment of the utility model, the first clamping member 110 includes a first supporting portion 111 and a first abutting portion 112, the first supporting portion 111 abuts against one end of the workpiece to be processed, and the first supporting portion 111 is arranged on the side of the first abutting portion 112 away from the workpiece to be processed; similarly, the second clamping member 120 includes a second supporting portion 121 and a second abutting portion 122, the second supporting portion 121 abuts against the other end of the workpiece to be processed, and the second supporting portion 121 is arranged on the side of the second abutting portion 122 away from the workpiece to be processed. It can be understood that such a configuration can facilitate the assembly of the first clamping member 110 and the second clamping member 120 with the device body.

[0048] The second aspect of the utility model provides a processing device for zirconia ceramic blocks, the processing device includes a device body and a fixture as described in any of the aforementioned embodiments, the fixture is arranged on the device body, specifically, the adaptive setting of the prior art can be referred to, and the utility model is an embodiment and will not be repeated here.

[0049] It should be noted that the technical solutions in various embodiments of the present utility model can be combined with each other, but the basis for the mutual combination is that it can be implemented by ordinary technicians in the field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist, that is, it does not belong to the protection scope of the present utility model.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
