Description

Technical Field

[0001] This utility model relates to the field of CNC lathes, and in particular to a grinding wheel dressing device for a turning-grinding CNC lathe. Background Technology

[0002] Numerical control machine tools are short for computer numerical control machine tools. They are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, and thus enable the machine tool to move and process parts.

[0003] When machining on a turning-grinding CNC lathe, a grinding wheel is used to grind the workpiece. After high-speed grinding, the working surface of the grinding wheel needs to be repaired. Most existing lathes require the grinding wheel to be removed for repair, which is troublesome and reduces machining efficiency. Utility Model Content

[0005] A grinding wheel dressing device for a CNC lathe with a turning and grinding system includes a spindle box installed inside the lathe.

[0006] A corrector seat is provided on the rear side of the spindle box. A trimming arm is provided on the side of the corrector seat away from the spindle box. The trimming arm is parallel to the axis of the working end of the spindle box. One end of the trimming arm protrudes outward from the corrector seat and is provided with a pen holder. A correction pen is provided on the side of the pen holder close to the spindle box. The correction pen is perpendicular to the trimming arm.

[0007] As a further embodiment of this utility model: a cross-shaped mounting groove is provided on the side of the trimming arm near the pen holder, and a straight mounting seat is provided on the pen holder corresponding to the mounting groove. The pen holder is fixedly installed in the mounting groove by the mounting seat.

[0008] As a further embodiment of this utility model: a keyway is provided at the upper end of the pen holder, and a flat key is provided inside the keyway. The flat key is fixedly connected to the trimming arm through the mounting groove.

[0009] As a further embodiment of this utility model: a connecting plane is provided on the side of the trimming arm near the corrector seat, and multiple mounting holes are provided on the side of the trimming arm near the corrector seat, with the mounting holes extending inward to the corrector seat.

[0010] As a further embodiment of this invention, the correction pen is a diamond pen.

[0011] As a further aspect of this invention, the correction pen has a retractable structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a dressing arm and a correction pen on the rear side of the spindle box, the dressing arm is set parallel to the axis of the working end of the spindle box, and the correction pen is set perpendicular to the dressing arm, ensuring that the correction pen is set perpendicular to the grinding wheel. The grinding wheel will be dressed once before grinding, adjusting the parallelism between the grinding wheel and the axis of the spindle box. The correction pen breaks the abrasive passivation layer of the grinding wheel, exposing a new cutting edge, ensuring the surface finish of the workpiece.

[0024] Please see Figure 1-4 A grinding wheel dressing device for a CNC lathe with a turning and grinding system includes a spindle box 1 installed inside the lathe.

[0025] A corrector seat 2 is provided on the rear side of the spindle housing 1. A trimming arm 3 is provided on the side of the corrector seat 2 away from the spindle housing 1. The trimming arm 3 is parallel to the axis of the working end of the spindle housing 1. One end of the trimming arm 3 protrudes outward from the corrector seat 2 and is provided with a pen holder 4. A correction pen 5 is provided on the side of the pen holder 4 close to the spindle housing 1. The correction pen 5 is perpendicular to the trimming arm 3.

[0026] Before grinding, the dressing arm 3 and the working end of the spindle box 1 are set parallel to each other, and the correction pen 5 and the dressing arm 3 are set perpendicular to each other. By utilizing the coaxiality between the grinding wheel and the spindle box 1, the correction pen 5 is set perpendicular to the grinding wheel. The grinding wheel is corrected by the correction pen 5, breaking the abrasive passivation layer of the grinding wheel and exposing the new cutting edge. The parallelism between the axis of the grinding wheel and the spindle box 1 is adjusted, which facilitates the subsequent grinding of the workpiece.

The flat key 9 is fixedly connected to the trimming arm 3 by the mounting groove 6.

[0028] By using the mounting slot 6 and mounting base 7, along with the flat key 9, the pen holder 4 can be positioned and installed to ensure that the correction pen 5 is set perpendicular to the trimming arm 3; the flat key 9 plays a guiding, limiting and fixing role for the pen holder 4.

[0029] A further solution: A connecting plane 10 is provided on the side of the trimming arm 3 near the corrector seat 2, and a plurality of mounting holes 11 are provided on the side of the trimming arm 3 near the corrector seat 2, with the mounting holes 11 extending inward to the corrector seat 2.

[0030] It enables the trimming arm 3 to be securely mounted on the corrector seat 2, while improving the stability of the correction pen 5 during operation.

[0031] Further proposed solutions: Correction pen 5 is a diamond pen; correction pen 5 has a retractable structure.

[0032] It can effectively improve the correction efficiency of the correction pen 5 on the grinding wheel.
