[0020] The concept, specific structure and technical effects of the present application will be described clearly and completely in combination with embodiments and drawings, so as to fully understand the purpose, features and effects of the present application. Each technical feature in the present application can be combined interactively without conflict.

[0021] The structure of the grinding wheel blank generally comprises a blank 10 and a base body 20, wherein the base body 20 is composed of a handle part and a head part, the blank 10 is solidified with the head part of the base body 20 after sintering, and the handle part of the base body 20 is connected with external equipment during use.

[0022] As shown in a structure of an existing grinding wheel rod, Figure 1 the handle part of the base body 20 is in a rod structure, and a protrusion extends upward from the center of the top surface of the handle part, the blank 10 completely covers the protrusion after sintering, and also covers and bonds with the top surface of the handle part, and the protrusion and the top surface of the handle part are the head part of the base body 20.

[0023] As shown in another structure of an existing grinding wheel rod, Figure 2 the structure is different from the first structure in that the top surface of the handle part is not provided with a protrusion, and the top surface of the handle part is completely bonded with the blank 10 after sintering, and the top surface of the handle part is the head part of the base body 20.

[0024] The blank 10 of the above two grinding wheel rods has a part exceeding the head part of the base body 20, and during sintering, the blank 10 will appear to be molten and liquefied, and has certain viscosity and flowability, and the part of the blank 10 outside the head part of the base body 20 without support is prone to flow under the action of gravity, resulting in deformation and falling of the blank. Therefore, the prior art adopts a supporting piece arranged on the base body 20 to completely support the bottom surface of the blank 10, but after sintering, the supporting piece needs to be removed in a subsequent trimming process, and at the same time, the trimming process is also prone to affecting the performance of the grinding wheel.

[0025] To this end, the present application provides a technical scheme of an auxiliary jig for grinding wheel sintering, Figure 4 and Figure 5As shown, the structure comprises a limiting mechanism and an isolation layer. The limiting mechanism is used to limit the handle of the base 20, so that the base 20 remains in a vertical state, and the part of the handle of the base 20 can be adjusted in height up and down. The isolation layer is a dense coating which does not react with the blank 10 when sintering, and is coated on the limiting mechanism and can move to the bottom surface of the part of the blank 10 beyond the head of the base 20 when the limiting mechanism is adjusted in height. After the handle of the base 20 is limited by the limiting mechanism, the height of the limiting mechanism is adjusted so that the isolation layer rises to the bottom surface of the part of the blank 10 beyond the head of the base 20. Since the isolation layer does not react with the blank 10 when sintering, the limiting mechanism and the isolation layer can be removed after sintering, and the sintered grinding wheel rod product is obtained.

[0026] In an embodiment, as shown in Figure 4 and Figure 5 , the limiting mechanism comprises a height adjusting mechanism 1 and a supporting mechanism 2. The supporting mechanism 2 is used to clamp the handle of the base 20, so that the base 20 remains in a vertical state. The supporting mechanism 2 is arranged on the height adjusting mechanism 1, and can move up and down and remain at different heights under the adjustment of the height adjusting mechanism 1. The isolation layer is coated on the supporting mechanism 2, so that the isolation layer can move up and down with the supporting mechanism 2.

[0027] In an embodiment, as shown in Figure 4 and Figure 5 , the supporting mechanism 2 comprises a tray 21, a supporting sheet and a fixing mechanism. The tray 21 is arranged on the height adjusting mechanism 1 and can move up and down with the adjustment of the height adjusting mechanism 1. The supporting sheet is placed on the top surface of the tray 21, and can form clamping and limiting to the handle of the base 20 after being detachably fixed on the tray 21 by the fixing mechanism. The tray 21 and the supporting sheet are both provided with through holes, so that the handle of the base 20 passes through and the through hole of the supporting sheet clamps and limits the outer side surface of the handle of the base 20. In addition, the isolation layer is coated on the top surface of the supporting sheet, so that the supporting sheet clamps and limits the handle of the base 20 at the same time, and the isolation layer abuts against the bottom surface of the blank 10.

[0028] In order to facilitate the clamping and dismounting of the supporting sheet to the handle of the base 20, the supporting sheet is arranged in a structure surrounded by at least two sub-supporting sheets 22, as shown in Figure 4 and Figure 5 . The supporting sheet is surrounded by three sub-supporting sheets 22, of course, two or four or more can also be used, and three is preferred. The fixing mechanism uses the same number of fixing pieces 23 as the number of sub-supporting sheets 22, and each fixing piece 23 is used to fix a sub-supporting sheet 22. Similarly, the isolation layer comprises the same number of sub-isolation layers as the number of sub-supporting sheets 22, and a sub-isolation layer is coated on the top surface of a sub-supporting sheet 22. After the sub-supporting sheets 22 form a complete supporting sheet, the sub-isolation layers also form a complete isolation layer.

[0029] In one embodiment, such as Figure 5 As shown, the same number of strip grooves 211 as the sub-support plates 22 are formed on the material tray 21. These strip grooves 211 are arranged around the through holes of the material tray 21 and are arranged radially. The fixing member 23 is a V-shaped elastic member composed of two elastic arms. The intersection of the two elastic arms abuts against the bottom surface of the material tray 21. Both elastic arms pass through the strip grooves 211 from bottom to top. The end of one elastic arm abuts against the top surface of the material tray 21 on both sides of the strip groove 211, and the end of the other elastic arm presses against the corresponding sub-support plate 22. For different sized base 20 handles, corresponding sized sub-support plates 22 are used. At the same time, the fixing member 23 can also be moved along the strip grooves 211 to a suitable position to press the sub-support plate 22. When disassembling after sintering, the fixing member 23 can also be moved outward to disengage it from the sub-support plate 22, so that the sub-support plate 22 can be removed, making disassembly more convenient.

[0030] In one embodiment, such as Figure 4 and Figure 5 As shown, the height adjustment mechanism 1 includes a base 11, three non-linear support columns 12, and adjustment blocks 13, the same number as the support columns 12, each corresponding to one of the support columns 12. There can be four or more support columns 12, preferably three. The support columns 12 are threaded rods, and the adjustment blocks 13 are adjusting nuts. The three adjusting nuts are threadedly connected to the three threaded rods, and each adjusting nut can be adjusted independently. The material tray 21 has limiting holes 212 corresponding to the threaded rods. The material tray 21 allows the threaded rods to pass through the corresponding limiting holes 212 and be placed on the adjusting nuts. By rotating the adjusting nuts to different heights on the threaded rods, the height of the material tray 21 can be adjusted. The use of adjusting nuts and threaded rods results in a relatively simple and reliable structure.
