[0012] (3) Beneficial effects

[0013] This utility model provides a grinding wheel dressing device, overcoming the shortcomings of existing grinding wheel dressing devices, which can only dress a single grinding wheel at a time, resulting in low efficiency and inability to dress grinding wheels of different sizes, thus lacking practicality. Compared with the prior art, this utility model has the following beneficial effects:

[0014] 1. By rotating the handle, the connecting cylinder is moved, causing the grinding wheel to be dressed to come into contact with the dressing wheel. The motor is started to drive the drive mechanism, which drives the second pulley to rotate. Since the first pulley and the second pulley are connected by a belt, the grinding wheel to be dressed and the dressing wheel rotate simultaneously, thus achieving the dressing of the grinding wheel. Because two rotating shafts are set, two grinding wheels can be dressed at the same time, improving work efficiency.

[0015] 2. By rotating the handle, the connecting cylinder is moved, thereby adjusting the distance between the grinding wheel to be dressed and the dressing wheel to accommodate grinding wheels of different sizes, making it highly practical. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1-4 As shown, the grinding wheel dressing device of this utility model includes a frame 1, a connecting cylinder 2, a rotating shaft 3, a first pulley 4, a mounting box 5, a motor 6, a drive mechanism 7, a second pulley 8, a belt 9, a dressing wheel 10, a pitch adjustment assembly, and a tensioning mechanism 14. The connecting cylinder 2 is provided inside the frame 1, and both ends of the connecting cylinder 2 extend outside the frame 1. The rotating shaft 3 is rotatably mounted on both ends of the connecting cylinder 2, and the first pulley 4 is fixedly connected to the rotating shaft 3. The mounting box 5 is provided on the top of the frame 1, and the motor 6 is mounted on the top of the mounting box 5. The drive mechanism 7 includes a first bevel gear 71, a second bevel gear 72, and a connecting shaft 73. The first bevel gear 72 is fixedly connected to the output shaft of the motor 6. Gear 71, the connecting shaft 73 is rotatably mounted on both sides of the mounting box 5, one end of the connecting shaft 73 is fixedly connected to the second bevel gear 72, the second bevel gear 72 meshes with the first bevel gear 71, the other end of the connecting shaft 73 is fixedly connected to the second pulley 8 and the dressing wheel 10, the first pulley 4 and the second pulley 8 on each side of the frame 1 are connected by the belt 9, the mounting box 5 is provided with a tensioning mechanism 14 for adjusting the tension of the belt 9, the frame 1 and the connecting cylinder 2 are provided with a distance adjustment component for adjusting the distance between the grinding wheel 15 and the dressing wheel 10, the grinding wheel 15 is fixedly mounted on the rotating shaft 3 by a fixing nut 16.

[0023] The adjusting assembly includes a screw 12 and a handle 13. One end of the screw 12 passes through the frame 1 and is rotatably connected to the inner wall of the sleeve 21 on one side of the connecting cylinder 2. The other end of the screw 12 is connected to the handle 13. A nut 11 for threaded connection with the screw 12 is provided on one side of the frame 1.

[0024] The sleeve 21 is provided with a T-shaped disc groove 211 in the axial section. The screw 12 is provided with a boss 121 that matches the disc groove 211 at one end inside the sleeve 21. The boss 121 and the disc groove 211 are in clearance fit. This arrangement can effectively prevent the screw 12 from disengaging from the sleeve 21.

[0025] The tensioning mechanism 14 includes a bracket 141, a tensioning wheel 142, a tensioning arm 143, and a torsion spring 144. The bracket 141 is fixed on the mounting box 5.

[0026] In actual operation, the grinding wheel 15 to be dressed is installed on the rotating shaft 3 by fixing nut 16. After the grinding wheel 15 is installed, the connecting cylinder 2 is moved by rotating handle 13 so that the grinding wheel 15 to be dressed comes into contact with the dressing wheel 10. Then, the motor 6 is started to drive the first bevel gear 71 to rotate. The first bevel gear 71 meshes with the second bevel gear 72 and drives it to rotate. The rotation of the second bevel gear 72 drives the connecting shaft 73 to rotate. Since the first pulley 4 and the second pulley 8 are connected by belt 9, the grinding wheel 15 to be dressed and the dressing wheel 10 are rotated at the same time, thus achieving the dressing of the grinding wheel 15. Because of the two rotating shafts 3, two grinding wheels 15 can be dressed at the same time, improving work efficiency. Rotating the handle 13 moves the connecting cylinder 2, thus adjusting the distance between the grinding wheel 15 to be dressed and the dressing wheel 10 to accommodate grinding wheels 15 of different sizes, making it highly practical. However, adjusting the distance between the grinding wheel 15 and the dressing wheel 10 causes changes in the first pulley 4 and the second pulley 8. Therefore, it is necessary to rotate the tensioning arm 143 to drive the tensioning wheel 142 to tension the belt 9, thereby adjusting the tension of the belt 9 to ensure the normal rotation of the grinding wheel 15 and the dressing wheel 10. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0027] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
