[0033] In summary, this embodiment can reduce the manufacturing difficulty by making the product positioning support structure and the base 1 manufactured and assembled separately, and when the product is replaced, it is only necessary to replace the product positioning support structure with one corresponding to the product, so the replacement is quick and convenient.

[0034] The product positioning support structure can be separately disassembled from the base 1. Compared with the traditional integral structure, the integral structure is improved into a split structure in which the base 1 and the product positioning support structure are separable. When replacing the processed product, it is only necessary to separately disassemble the product positioning support structure and replace the product positioning support structure corresponding to the product model. The base 1 does not need to be disassembled, which reduces the overall processing material loss cost of the fixture, has high changeover efficiency, and strong versatility.

[0035] Moreover, the plate body 3 is located in the groove 2 and can withstand the grinding pressure parallel to the plate body without loosening.

[0036] Moreover, the arc block 10 can be provided to divide a single circular ring into multiple sections, which can not only meet the positioning needs, but also adapt to the situation of different product shapes, improve the universal ability, and also reserve space for installing the positioning pin 8 to reduce the difficulty of arrangement.

[0037] In some specific embodiments of the present invention, the groove bottom of the groove 2 can be connected to the plate body 3 by bolts to simplify the installation. Moreover, the installation operation conforms to the characteristics of human mechanics and reduces labor intensity.

[0038] Reference Figure 4 In some specific embodiments of the present invention, the outer contour of the plate body 3 can be matched with the inner wall of the groove 2, and the outer contour of the plate body 3 is provided with a side cut portion, which is used to form a gap 13 between the outer contour of the plate body 3 and the side wall of the groove 2.

[0039] It is easy to understand that, by providing the side cut portion, this embodiment can reserve a gap to facilitate the discharge or entry of air without affecting disassembly and assembly, and it is also convenient to pry the plate body 3 when it is adhered to the groove 2, thereby facilitating disassembly.

[0040] Reference Figure 3 In some specific embodiments of the present invention, a plurality of mounting holes 12 may be provided on the top of the base 1, the plurality of mounting holes 12 are arranged around the outside of the groove 2, a mounting hole 11 is provided on the side of the base 1, and an annular shoulder is provided on the bottom of the base 1.

[0041] Therefore, fixation is accomplished through the second mounting hole 12, rotation is restricted through the first mounting hole 11, and the annular shoulder can achieve center positioning to reduce position deviation.

[0042] In some specific embodiments of the present invention, the slot 4 can be connected vertically, and the pin hole 5 can be connected vertically, so as to reduce the manufacturing difficulty and facilitate disassembly and assembly.

[0043] In some specific embodiments of the present invention, the arc block 10 can be integrally fixed to the plate body 3 to simplify installation.

[0044] In detail, Figures 1 to 4In the figure, there are marked base 1, groove 2, plate 3, slot 4, pin hole 5, fixing hole 1 6, center column 7, positioning pin 8, fixing hole 2 9, arc block 10, mounting hole 1 11, mounting hole 2 12, and notch 13. A groove 2 is provided on the top surface of the base 1, and a plate 3 is embeddedly installed on the inner side of the groove 2. A slot 4 is provided in the middle of the top surface of the plate 3, and a center column 7 is insert-installed on the inner side of the slot 4. A pin hole 5 is provided on the top surface of the plate 3, and a positioning pin 8 is insert-installed on the inner side of the pin hole 5. A fixing hole 1 6 is provided on the inner side of the groove 2, a fixing hole 2 9 is provided on the top surface of the plate 3, an arc block 10 is fixedly installed on the top surface of the plate 3, a mounting hole 11 is provided on the side of the base 1, and a mounting hole 2 12 is provided on the side of the top surface of the base 1.

[0045] Specifically, the fixing hole 1 6 is a threaded hole, the fixing hole 2 9 is a countersunk hole, and there are two fixing holes 1 6 and two fixing holes 2 9 respectively, and the fixing hole 1 6 and the fixing hole 2 9 correspond to each other up and down. The plate body 3 is fixedly connected to the base 1 by bolts passing through the fixing hole 2 9 and the fixing hole 1 6.

[0046] It can be understood that the base 1 is fixedly mounted on the surface grinding machine by bolts passing through the mounting hole 11 and the mounting hole 2 12, so that the base 1 is fixedly mounted separately, and the plate body 3 can be removed separately from the base 1. Compared with the traditional integral structure, the integral structure is improved into a split structure in which the base 1 and the plate body 3 are separable. When replacing the processed product, it is only necessary to disassemble the plate body 3 separately and replace the plate body 3 corresponding to the product model. The base 1 does not need to be disassembled, which reduces the overall processing material loss cost of the fixture, has high changeover efficiency, and strong versatility.

[0047] Specifically, the inner diameter of the slot 4 is the same as the diameter of the central column 7 .

[0048] It can be understood that the center column 7 is used to be inserted into the inner side of the slot 4 to position the flange.

[0049] Specifically, two pin holes 5 are provided on the left and right sides of the top surface of the plate body 3 .

[0050] It can be understood that by inserting the locating pin 8 into the pin hole 5, the product is positioned using the center column 7, the locating pin 8 and the arc block 10. The specific position and diameter of the locating pin 8 and the pin hole 5 are not limited. The pin holes 5 and the arc block 10 on different models of plates 3 correspond to different models of flange products. Therefore, when replacing the product, it is only necessary to replace the plate 3 with the one corresponding to the product, and the replacement is quick and convenient.

[0051] Specifically, the left side of the plate body 3 is a plane structure, the groove 2 is a circular structure, and the inner diameter of the groove 2 is the same as the diameter of the plate body 3 , and a gap 13 is formed between the plane structure and the groove 2 .

[0052] It is understandable that, during the process of disassembling the plate body 3 , disassembly is more convenient through the notch 13 .

[0053] Working principle: First, the base 1 is fixedly installed on the surface grinding machine by passing bolts through the mounting hole 11 and the mounting hole 2 12 to realize the independent fixed installation of the base 1. The positioning pin 8 is inserted into the pin hole 5, and the product is positioned by using the center column 7, the positioning pin 8 and the arc block 10. The specific position and diameter of the positioning pin 8 and the pin hole 5 are not limited. The pin holes 5 and the arc block 10 on the different types of plates 3 correspond to the flange products of different types. Therefore, when replacing the product, it is only necessary to replace the plate 3 with the one corresponding to the product, and the replacement is fast. The plate body 3 can be removed separately from the base 1. Compared with the traditional integral structure, the integral structure is improved into a split structure in which the base 1 and the plate body 3 are separable. When replacing the processed product, it is only necessary to remove the plate body 3 separately and replace the plate body 3 corresponding to the product model. The base 1 does not need to be removed, which reduces the overall processing material loss cost of the fixture. The changeover efficiency is high and the versatility is strong. A gap 13 is formed between the plane structure and the groove 2. During the disassembly of the plate body 3, the disassembly is more convenient through the gap 13.
