Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0019] Such as figure 1 and figure 2 , a new CNC grinding wheel dressing device for a screw rotor grinder, including a motor 1, two couplings 2, a servo motor I3, a vertical guide rail 4, an upper carriage 5, a horizontal guide rail 6, and two diamond wheels 7. A lower carriage 8, a servo motor II9, a pulley mechanism 10 and two ball screw mechanisms 11.

[0020] The new CNC grinding wheel dressing of the screw grinder adopts a two-coordinate feed mechanism perpendicular to each other, which is divided into horizontal feed and vertical feed. Servomotor 13 and shaft coupling 2 and ball screw mechanism 11 drag lower carriage 8 to realize that lower carriage 8 is vertically fed together with the horizontal feed mechanism installed thereon. Servomotor II9 and shaft coupling 2 and ball screw mechanism 11 drag upper carriage 5, and realize upper carria...

Abstract

The invention discloses a novel numerical-control grinding wheel dressing device, which comprises a motor (1), two couplers (2), a servo motor I (3), a vertical guide track (4), an upper carriage (5), a horizontal guide track (6), two diamond wheels (7), a lower carriage (8), a servo motor II (9), a belt pulley mechanism (10) and two ball screw mechanisms (11). Two plane rectangular coordinate feeding mechanisms which are mutually perpendicular are formed, and numerical-control interpolation of the diamond wheels in the same plane is realized. Accordingly, automatic and numerical-control shape modification of grinding wheels in screw grinding machines is realized, precision of section shapes of dressed grinding wheels is high, efficiency is high, a shape modification process is simple and convenient in operation without limitation of experience.

Description

technical field [0001] The invention belongs to the technical field of grinding processing and grinding machines, and relates to a numerically controlled grinding wheel dressing device for grinding screw rotors with complex profiles, which is used for profile dressing of grinding wheels for grinding precision and complex helical surface parts such as screw rotors and worms. Background technique [0002] Screw rotor grinding machine is a special precision machining equipment used for grinding precision and complex helical surface parts such as screw rotors and worms. When the workpiece is ground, the wear of the grinding wheel exists all the time. The redressing of the grinding wheel is an important task of the screw rotor grinder, and it is an important means to ensure the grinding accuracy and processing quality of the workpiece. Due to the difference in the surface shape of the helicoidal workpiece, the requirements for the section shape of the grinding wheel are also diff...
