Numerical control groove grinding machine with numerical control grinding wheel trimming device

Abstract

The invention relates to a numerical control groove grinding machine tool used for grinding grooves of cutting tools, such as drill bits, taps, milling cutters, center drills and the like, in particular to a numerical control groove grinding machine with a grinding wheel trimming device. The trimming part comprises a diamond pen positioned above the top part of a grinding wheel of a grinding head, the diamond pen is mounted at the front end of a rotating arm, the back end of the rotating arm is connected on the edge of a rotating disk, and the rotating disk is driven by a rotating numerical control motor; the rotating numerical control motor is mounted on a horizontal sliding block, the horizontal sliding block is mounted on an encloser part and can move horizontally along a horizontal guide track, the trend of the horizontal guide track is parallel to the axial direction of the grinding wheel of the grinding head, and the horizontal sliding block is driven by a horizontal movement numerical control motor through a horizontal screw rod; and the encloser part is connected on a vertical sliding block, the vertical sliding block is driven by a vertical movement numerical control motor through a vertical screw rod for moving in the vertical direction, and the vertical movement numerical control motor is mounted on a fixed frame of the groove grinding machine. The numerical control groove grinding machine has simple structure and convenient manufacture, and can trim the grinding wheels in various cross section shapes and be easy to realize the digital control.

Description

technical field [0001] The invention relates to a numerically controlled groove grinding machine tool for grinding grooves of tools such as drills, taps, milling cutters, and center drills, in particular to a numerically controlled groove grinding machine with a numerically controlled grinding wheel dressing device. Background technique [0002] CNC groove grinding machine tools used to grind grooves on tools such as drills, taps, milling cutters, and center drills usually include grinding head parts for grinding grooves, lifting parts that control the lifting of the grinding head, and spindles that control the movement of the workpiece Transmission components, numerical control systems that coordinate the actions of various parts, etc. Some groove grinding machines also include a trimming part used to trim the edge section of the grinding wheel. The function of the grinding wheel trimming part is to trim the edge of the grinding wheel to a shape consistent with the groove s...

Problems solved by technology

But this structure is not suitable for diamond pens with sharp corners. The reason is that under this structure, the axis direction of the diamond pen is always consistent with the radial direction of the grinding wheel. The protective welding layer will be ground by the grinding wheel to cause interference and damage
