The side wall of the spindle 1 is provided with a position-adjustable second grinding wheel holder 4. One end of the second grinding wheel holder 4 is provided with a second positioning bolt 7. The second grinding wheel holder 4 is fixedly connected to the spindle 1 by the second positioning bolt 7. The side wall of the first grinding wheel holder 2 is fixedly connected with equidistantly distributed first cylindrical grinding wheels 3, and the side wall of the second grinding wheel holder 4 is fixedly connected with second cylindrical grinding wheels 5.

[0020] Based on the above structure, during use, by adjusting the position of the second cylindrical grinding wheel 5 to cooperate with one of the first cylindrical grinding wheels 3, a stepped grinding wheel structure can be formed. When grinding the T-shaped bushing, both shafts of the T-shaped bushing can be ground simultaneously, thereby improving grinding efficiency.

[0021] like Figure 3 As shown, a slot 11 is provided on one side of the outer wall of the spindle 1, which is equidistant from the axis of the spindle 1. A first through hole 12 is provided on the side wall of the slot 11. The first mold holder 2 includes a sleeve 21 that is slidably connected to the outer wall of the spindle 1. A plurality of first mounting cylinders 22 are provided at one end of the sleeve 21 and are fixedly connected in sequence. The diameter of the plurality of first mounting cylinders 22 increases in sequence. One end of one of the first mounting cylinders 22 is fixedly connected to an end ring 23. A first positioning bolt 6 is provided on the sleeve 21 and passes through the first through hole 12. A plurality of first cylindrical molds 3 are respectively fixedly sleeved on the outer wall of the plurality of first mounting cylinders 22.

[0022] According to the above structure, when the first cylindrical grinding mold 3 needs to be replaced, the sleeve 21 together with several first mounting cylinders 22 is pulled outward by unscrewing the first positioning bolt 6, thereby removing the first grinding mold frame 2 as a whole and the first cylindrical grinding mold 3 installed on the first grinding mold frame 2, and replacing it with a new first grinding mold frame 2 and the first cylindrical grinding mold 3. The diameter of several first mounting cylinders 22 increases sequentially, which can process T-shaped bushings of different sizes and specifications.

[0023] like Figure 3 As shown, the inner wall of the first mounting cylinder 22 is fixedly connected with support plates 24 that are equidistantly distributed around the axis of the first mounting cylinder 22, and the support plates 24 are slidably connected inside the corresponding slots 11.

[0024] According to the above structure, the support plate 24 is slidably connected inside the slot 11, and the support plate 24 plays the role of supporting the first mounting cylinder 22, providing strength and stability to the first mounting cylinder 22.

[0025] like Figure 3 As shown, a sliding groove 13 is symmetrically arranged on the other side of the outer wall of the spindle 1. A positioning groove 14 is equidistantly distributed on one side of the sliding groove 13. A second through hole 15 is equidistantly distributed on the side wall of one of the sliding grooves 13. The second through hole 15 passes through the spindle 1. The second mold holder 4 includes a second mounting cylinder 41. A positioning cylinder 42 is fixedly connected to one end of the second mounting cylinder 41. The positioning cylinder 42 is sleeved on the outer wall of the spindle 1. A locking block 43 is symmetrically arranged on the inner wall of the positioning cylinder 42. The two locking blocks 43 are respectively engaged and connected inside the two positioning grooves 14. A second positioning bolt 7 is arranged on the positioning cylinder 42. The second positioning bolt 7 passes through the second through hole 15. The second cylindrical mold 5 is fixedly sleeved on the outer wall of the second mounting cylinder 41.

[0026] Based on the above structure, during use, the position of the second cylindrical mold 5 is adjusted according to the difference in diameter between the two cylinders of the T-shaped bushing so that it matches the corresponding first cylindrical mold 3. When adjusting the position of the second cylindrical mold 5, the second positioning bolt 7 is unscrewed, the second mounting cylinder 41 is rotated so that the two locking blocks 43 are respectively rotated into the two sliding grooves 13. Then, the second mounting cylinder 41 is slid to the corresponding position, and then the second mounting cylinder 41 is reversed so that the two locking blocks 43 slide into the corresponding two positioning grooves 14. Then, the second positioning bolt 7 is passed through the corresponding second through hole 15 to fix the position of the second mold holder 4.

[0027] The working principle of this utility model is as follows: During use, by adjusting the position of the second cylindrical grinding tool 5 to mate with one of the first cylindrical grinding tools 3, a stepped grinding tool structure is formed. When grinding the T-shaped bushing, both cylinders of the T-shaped bushing can be ground simultaneously, improving grinding efficiency. When the first cylindrical grinding tool 3 needs to be replaced, by unscrewing the first positioning bolt 6, the sleeve 21, along with several first mounting cylinders 22, is pulled outwards, thereby removing the entire first grinding tool frame 2 and the first cylindrical grinding tool 3 mounted on it. A new first grinding tool frame 2 and a new first cylindrical grinding tool 3 are then installed. The diameters of the several first mounting cylinders 22 increase sequentially, allowing for the processing of T-shaped bushings of different sizes and specifications. Support plate 2... 4. The sliding connection is inside the slot 11. The support plate 24 supports the first mounting cylinder 22, providing strength and stability to the first mounting cylinder 22. During use, the position of the second cylindrical mold 5 is adjusted according to the difference in diameter between the two cylinders of the T-shaped bushing so that it matches the corresponding first cylindrical mold 3. When adjusting the position of the second cylindrical mold 5, the second positioning bolt 7 is unscrewed, and the second mounting cylinder 41 is rotated so that the two locking blocks 43 are respectively rotated into the two sliding grooves 13. Then, the second mounting cylinder 41 is slid to the corresponding position, and then the second mounting cylinder 41 is reversed so that the two locking blocks 43 slide into the corresponding two positioning grooves 14. Then, the second positioning bolt 7 is passed through the corresponding second through hole 15 to fix the position of the second mold holder 4.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
