[0050] like Figure 1-Figure 7 As shown, the utility model provides a grinding wheel dressing tool for dressing a grinding wheel.

[0051] The grinding wheel dressing tool comprises a base 1, a sliding assembly 2, a clamp assembly 3 and a dressing block 4. The base 1 can be locked to a machine tool; the sliding assembly 2 comprises a fixed portion 21 and a sliding portion 22, the fixed portion 21 is connected to the base 1, and the sliding portion 22 is slidably arranged on the fixed portion 21; the clamp assembly 3 is configured to be arranged on the sliding portion 22 at an adjustable angle on a horizontal plane, the clamp assembly 3 can be locked to the sliding portion 22, and the clamp assembly 3 is provided with a clamping groove; the dressing block 4 is in an elongated strip shape, the dressing block 4 can be locked in the clamping groove, and the dressing block 4 is configured to have sliding friction with the grinding wheel along the extension direction of the grinding wheel output shaft.

[0052] Before the dressing operation begins, the base 1 is first locked on the machine tool, and then the dressing block 4 is locked in the clamping groove, and the angle of the clamp assembly 3 on the horizontal plane is adjusted so that the dressing block 4 can be pressed against the grinding wheel along the extension direction of the grinding wheel output shaft to ensure the consistency of the grinding wheel dressing surface. Finally, the grinding machine is turned on to cause relative friction between the dressing block 4 and the grinding wheel. The worker pushes and pulls the sliding portion 22 along the fixed portion 21 by hand, so as to more accurately control the details of the dressing operation to complete the grinding wheel dressing operation. The grinding wheel can be completed without disassembling the grinding wheel, and the production cost is low, the operation efficiency is high, the installation is fast, no power supply is required, the angle dressing range is wide, and the dressing operation can also be carried out with the help of the rotation of the grinding wheel device itself.

[0053] In this embodiment, the trimming block 4 is an oilstone, and the base 1 is a special-shaped geometric structure in which a small rectangular block with a length of 20 mm, a width of 85 mm, and a height of 45 mm is cut off on one side of a rectangular structure with dimensions of 70 mm in length, 85 mm in width, and 110 mm in height. Four M6 bolt holes are provided on the top of the base 1, which can realize a detachable connection between the base 1 and the fixing part 21.

[0054] Specifically, refer to Figure 3 and Figure 4 The base 1 includes a base body 11, a first locking member 12 and an eccentric bolt 13. The base body 11 is provided with a threaded channel extending in the horizontal direction and a locking channel extending in the vertical direction, and the threaded channel is connected to the locking channel; the first locking member 12 is slidably arranged in the locking channel, and a locking hole is provided on the first locking member 12 that passes through in the horizontal direction, and the locking hole is connected to the locking channel; Figure 5 The eccentric bolt 13 is provided with an eccentric boss 131, and a locking groove is provided on the machine tool. The locking groove is connected to the locking channel. When the eccentric bolt 13 is screwed into the threaded channel, the eccentric boss 131 can extend into the locking hole and squeeze a part of the first locking member 12 into the locking groove. With the above arrangement, the first locking member 12 can be extended into the locking groove by rotating the eccentric bolt 13, so that the base body 11 cannot slide relative to the machine tool in the horizontal direction.

[0055] In this embodiment, the threaded channel has a diameter of 9 mm, the locking channel has a diameter of 18 mm and a length of 38 mm, and the locking hole has a diameter of 10 mm.

[0056] More specifically, the base 1 further comprises an elastic member 14, one end of which is connected to the inner wall of the locking channel, and the other end of which is connected to the first locking member 12. The arrangement of the elastic member 14 can provide elastic assistance when the worker rotates the eccentric bolt 13.

[0057] Specifically, the bottom surface of the base 1 is provided with two positioning grooves 15 at intervals, and the machine tool is provided with two positioning protrusions, and the positioning grooves 15 correspond to the positioning protrusions one by one. With the above arrangement, the positioning grooves 15 and the first locking member 12 cooperate to achieve positioning and locking of the base 1, and the stability is high.

[0058] Specifically, the fixing portion 21 is provided with a guide rail 211, and the sliding portion 22 is slidably matched with the guide rail 211. The above arrangement enables the sliding portion 22 to slide along the extending direction of the guide rail 211.

[0059] Specifically, the grinding wheel dressing tool also includes a limiting assembly 5, which includes a limiting plate 51, a limiting rod 52, a limiting nut 53 and a limiting block 54.

With the above arrangement, the limiting rod 52, the limiting nut 53 and the limiting block 54 cooperate, so that the limiting plate 51 can be pressed against the side of the base 1 away from the grinding wheel, thereby preventing the sliding part 22 from being separated from the guide rail 211.

[0060] More specifically, the first handle 511 is rotatably provided on one side of the limit block 54 away from the limit plate 51, and the first handle 511 can rotate in the plane where the limit rod 52 is located. The provision of the first handle 511 facilitates workers to find a comfortable angle before rotating the limit block 54.

[0061] More specifically, an arc-shaped transfer groove is provided on the side of the limit block 54 facing the first handle 511, in which a transfer buckle is fixedly arranged. The transfer buckle is cylindrical and has a threaded hole that passes through the axis of the limit rod 52. The limit rod 52 can pass through the threaded hole; the first handle 511 is rotatably connected to the transfer buckle to achieve angle adjustment in the plane where the limit rod 52 is located. The structure is simple and not easy to be damaged.

[0062] Specifically, the clamp assembly 3 includes a clamp seat 31 and a second locking member 32. The second locking member 32 is vertically penetrated in the clamp seat 31, and the second locking member 32 is screwed to the sliding portion 22. The second locking member 32 can press the clamp seat 31 against the sliding portion 22. The second locking member 32 is provided so that workers can adjust the angle of the dressing block 4 on the horizontal plane to adapt to grinding wheels at different positions.

[0063] Specifically, the clamp assembly 3 further includes a locking block 33 and a third locking member 34. The locking block 33 is arranged in the clamping groove; the third locking member 34 is screwed to the clamp seat 31, and the third locking member 34 can extend into the clamping groove and press the locking block 33 against the trimming block 4. With the above arrangement, the third locking member 34 cooperates with the locking block 33 to lock the trimming block 4 in the clamping groove, thereby preventing the trimming block 4 and the clamp assembly 3 from sliding relative to each other during the trimming operation, thereby improving the stability and success rate of the operation.

[0064] More specifically, three third locking members 34 are arranged at intervals along the extension direction of the clamping groove. The above arrangement makes the force of the locking block 33 in the clamping groove more uniform. In other embodiments, the number of the third locking members 34 can also be adjusted according to the volume of the trimming block 4, which is not limited here.

[0065] In this embodiment, the third locking member 34 is a bolt structure corresponding to an M4 threaded hole.
