[0016] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0017] Refer to Figures 1 to 4, the present utility model provides a grinding wheel dressing mechanism for an external cylindrical grinding machine, which includes a base 1 installed on the slide rail of the external cylindrical grinding machine. On the left and right sides of the upper end of the base 1, a left arc rail 3 and a right arc rail 2 are respectively arranged. A slideway 4 is angle-adjustably arranged on the coaxially arranged left arc rail 3 and right arc rail 2. The two arc rails are arranged to stably hold the slideway and the components thereon. The slideway 4 is locked to the right arc rail 2 by a third locking bolt 12. A T-shaped groove is opened along the length at the upper end of the slideway 4. A slider 5 slidably fitted along the T-shaped groove on the slideway 4 is locked by a first locking bolt 6. A clamping block 7 is hinged to the upper end of the slider 5. A dresser 8 locked by a second locking bolt 9 is inserted through the clamping block 7. The dresser can be adjusted left and right by the second locking bolt.

[0018] Both the right arc rail 2 and the left arc rail 3 are symmetrically arranged front and back and their cross-sections are both T-shaped. On the left and right sides of the lower end of the slideway 4, a right slider slidably fitted to the right arc rail 2 and a left slider slidably fitted to the left arc rail 3 are arranged. The slideway slides along the arc rail through the right slider slidably fitted to the right side of the right arc rail and the left slider slidably fitted to the left side of the left arc rail, thereby adjusting the angle of the slideway and the dresser.

[0019] The angles of the left arc rail 3 and the right arc rail 2 are the same. The angle of the left arc rail 3 is greater than or equal to 50 degrees and less than or equal to 80 degrees. Preferably, the angle of the left arc rail is 65 degrees.

[0020] Refer to Figure 1 、 Figure 3 , the slider 5 includes a bent portion 5.1 in an L shape. On the front and back sides of the upper end of the bent portion 5.1, front abutting portions 5.2 are symmetrically arranged. On the front and back sides of the left end of the bent portion 5.1, rear abutting portions 5.3 are symmetrically arranged. The upper end surfaces of the front abutting portions 5.2 and the rear abutting portions 5.3 are flush with the upper end surface of the bent portion 5.1. An elastic member is connected between the slider and the clamping block. When the clamping block abuts against the rear abutting portion, the dresser faces upward and is in an un-dressed state. The elastic member can pull the clamping block. When the clamping block abuts against the front abutting portion, the dresser faces right and is in a dressed state. The elastic member can pull the clamping block.

[0021] A cover plate 10 for covering the dresser 8 and in a concave shape is arranged at the top end of the clamping block 7. The cover plate is arranged to protect the dresser and prevent the staff from being injured by the dresser.

[0022] Refer to Figure 1 、 Figure 4 , a square hole is opened along the length direction at the top end of the cover plate 10. A pressure column 11 passes through the square hole and is elastically telescopically arranged in the clamping block 7. The pressure column 11 is elastically pressed against the cover plate 10. Pulling up the pressure column can loosen the cover plate. Adjusting the left and right positions of the cover plate and then loosening the pressure column can press the cover plate, which is simple and convenient.

[0023] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
