[0043] In other embodiments, the outer bottom surface of the outer U-shaped clamp body 4 is evenly provided with four titanium column fixing holes 45 and three glass ceramic fixing holes 41, that is, a glass ceramic fixing hole 41 is provided between two adjacent titanium column fixing holes 45, and a glass ceramic positioning pin 42 is installed next to each glass ceramic fixing hole 41. In addition, it is required that a gap be left between two adjacent glass ceramics 1 and titanium columns 2 installed on the outer bottom surface of the outer U-shaped clamp body 4.

[0047] During specific implementation, the glass ceramic identification number 44 corresponding to the glass ceramic fixing hole 41 on the outer bottom surface of the outer U-shaped clamp body 4 can be set to numbers 1, 2, and 3, and the titanium column identification number 46 corresponding to the titanium column fixing hole 45 on the outer bottom surface of the outer U-shaped clamp body 4 can be set to T1, T2, T3, and T4, so that the user can install the titanium column 2 and glass ceramic 1 with the required number according to processing requirements.

[0048] like Figure 5 As shown, the bottom of the front end surface of the outer U-shaped clamp body 4 is provided with a plurality of glass ceramic screw holes 43, and the glass ceramic screw holes 43 are interconnected with the corresponding glass ceramic fixing holes 41. The glass ceramic screw holes 43 can match with the glass ceramic fixing screws, and the junction of the glass ceramic screw holes 43 and the glass ceramic fixing holes 41 can match with the position of the screw fixing slot 14 of the glass ceramic 1.

[0049] In other embodiments, three glass ceramic screw holes 43 are evenly opened at the bottom of the front end surface of the outer U-shaped clamp body 4, and the number of glass ceramic screw holes 43 is the same as the glass ceramic fixing holes 41, that is, matching the three glass ceramic fixing holes 41 on the outer bottom surface of the outer U-shaped clamp body 4.

[0050] During specific implementation, the glass ceramic fixing screw is passed through the glass ceramic screw hole 43 to press the screw fixing groove 14 in the glass ceramic 1, so that the positioning operation is convenient and simple.

[0051] like Figure 5 , Figure 7 As shown, the inner bottom surface of the inner U-shaped clamp body 5 is semicircular, and a U-shaped titanium plate fixing step 51 is provided along the inner circumferential front of the inner U-shaped clamp body 5, and the U-shaped titanium plate fixing step 51 can match the titanium plate 3.

[0052] like Fig.10 , Fig.11 As shown, the front end surface of the inner U-shaped clamp body 5 is provided with a U-shaped fixing plate mounting groove 53, and the left and right sides and the bottom of the U-shaped fixing plate 6 are provided with fixing plate screw holes 61, and the front end surface of the inner U-shaped clamp body 5 is also provided with corresponding screw holes 54, which are used to install the U-shaped fixing plate 6 in the U-shaped fixing plate mounting groove 53 by screws, and the front end surface of the titanium plate 3 is flush with the end surface of the U-shaped fixing plate mounting groove 53.

[0053] In specific implementation, the utility model can process a titanium plate 3 with a fixed end 31 having a thickness of 10 mm and a diameter of 98 mm. Based on this, the thickness of the U-shaped fixed plate 6 can be set to 10 mm, the thickness of the inner U-shaped clamp body 5 can be set to 20 mm, and the thickness of the U-shaped fixed plate mounting groove 53 can be set to 10 mm, thereby meeting the fixed size of the titanium plate 3 on the market. In addition, the diameter of the semicircular inner bottom surface of the U-shaped titanium plate fixing step 51 can be set to 98.2 mm, thereby facilitating the loading and unloading of the titanium plate 3, so as to process more types of titanium teeth and increase the function of the fixture.

[0054] like Figure 8 As shown, a glass ceramic fixing hole 41 is respectively formed on the upper part of the two inner side surfaces of the inner U-shaped clamp body 5, and a corresponding glass ceramic positioning pin 42 is installed next to the glass ceramic fixing hole 41. Similarly, the glass ceramic fixing hole 41 can match the tail handle 13 of the glass ceramic 1; the glass ceramic positioning pin 42 can match the positioning groove 12 of the glass ceramic 1.

[0055] In specific implementation, the glass ceramic identification number 44 corresponding to the glass ceramic fixing hole 41 on the inner side of the inner U-shaped clamp body 5 is located on the front end surface on both sides of the outer U-shaped clamp body 4, and can be designed as L1 and L2, so that the user can install the glass ceramic 1 with the required number according to processing requirements.

[0056] Furthermore, two glass ceramic screw holes 43 are provided on the upper portion of the front end surface of the inner U-shaped clamp body 5, and the glass ceramic screw holes 43 are connected to the corresponding glass ceramic fixing holes 41 located on the upper portion of the inner side surface of the inner U-shaped clamp body 5. Similarly, the glass ceramic screw holes 43 can match the glass ceramic fixing screws; the junction of the glass ceramic screw holes 43 and the glass ceramic fixing holes 41 can match the position of the screw fixing groove 14 of the glass ceramic 1.

[0057] In specific implementation, the two glass ceramic fixing holes 41 can be set to Φ5.9x13mm, and the travel limit can be reduced by installing the glass ceramic 1 in the inner direction of the U-shaped fixing plate 6, and the two glass ceramic fixing holes 41, that is, any position of the label L1 or L2 can be selected for processing, providing a variety of options for the processing types of the glass ceramic 1. In addition, a gap is left between the glass ceramic 1 installed on the inner side of the inner U-shaped clamp body 5 and the titanium plate 3 installed in the U-shaped titanium plate fixing step 51.

[0058] In other embodiments, a mounting seat 49 is connected to the lower portion of an outer side surface of the outer U-shaped clamp body 4, and a position positioning hole 48 is opened at the upper portion.

[0059] In specific implementation, the position positioning hole 48 is used to locate the position of the fixture of the utility model, and the entire fixture is connected to the transmission shaft of the machine tool motor through the mounting seat 49. Due to the asymmetric design of the utility model, the locations marked L1 and L2 are far from the axis of the transmission shaft, and the outer bottom surface (i.e., the commonly used processing surface) of the outer U-shaped clamp body 4 is close to the axis of the transmission shaft, and the shorter force arm (i.e., the distance from the axis to the commonly used processing surface) can reduce the vertical downward pressure on the three glass ceramics 1 and the four titanium pillars 2 during the processing, thereby reducing the load on the motor, improving the processing accuracy, and increasing the service life of the motor.

[0060] like Figure 10-12 As shown, the specific use process of the utility model is as follows:

[0061] S1. Insert the tail handle 13 of the glass ceramic 1 to be processed into the glass ceramic fixing hole 41 through the guidance of the glass ceramic positioning pin 42, and push it until it contacts the outer bottom surface of the outer U-shaped clamp body 4. In addition, the glass ceramic positioning pin 42 and the glass ceramic fixing screw are fixed before the utility model leaves the factory, and at this time, tighten the glass ceramic fixing screw into the glass ceramic screw hole 43.

[0062] S2. Insert the titanium column 2 into the titanium column fixing hole 45 and push it until it contacts the outer bottom surface of the outer U-shaped clamp body 4, and tighten the titanium column fixing screw into the titanium column screw hole 23 from the U-shaped titanium plate fixing step 51 on the inner circumference of the U-shaped fixing plate 6.

[0063] S3, put the titanium plate 3 into the U-shaped titanium plate fixing step 51, and then place the U-shaped fixing plate 6 into the U-shaped fixing plate installation groove 53, and tighten them.

[0064] In summary, the utility model can be used not only to process glass ceramics 1, but also to process titanium columns 2, and even more to process titanium plates 3. It has an ingenious design, richer functions, is suitable for various styles of workpieces, is simpler to operate, and is more user-friendly.
