Numerically-controlled grinding machine for arced notch chamfer mill

Abstract

The invention belongs to the technical field of numerical control, and discloses a numerically-controlled grinding machine for an arced notch chamfer mill. The numerically-controlled grinding machine for the arced notch chamfer mill comprises a machine body, and a base mounted on the top part of the machine body; a longitudinal servo motor and a transverse servo motor are mounted on the base; rotating workbenches equipped with numerically-controlled dividing heads are arranged above the longitudinal servo motor and the transverse servo motor; a head grinding seat is arranged on the top part of each rotating workbench, comprising a grinding head, and an abrasive wheel mounted on the grinding head; a motor is arranged at one side of each abrasive wheel; each grinding head is connected with a cross sliding table, and the cross sliding table is connected with two cross sliding table servo motors, wherein the two cross sliding table servo motors are connected with abrasive wheel lifting motors through vertical columns; a nitrogen balancing cylinder is mounted on the vertical columns. The numerically-controlled grinding machine for the arced notch chamfer mill has the advantages that a notch with the shape as required can be grinded at a time, so that the production efficiency can be greatly raised, and the cost is low.

Description

technical field [0001] The invention relates to a numerical control groove grinding machine, in particular to a numerical control groove grinding machine for an arc groove chamfering knife, which belongs to the technical field of numerical control. Background technique [0002] The chamfering knife is a tool that is assembled on the milling machine, drilling machine, planer, chamfering machine and other machine tools to process the 60-degree or 90-degree chamfering and taper hole of the workpiece, and the chamfering tool. The traditional chamfering knife adopts a straight groove. Small chip space and weak tooth back strength cannot adapt to the current high-speed and high-efficiency machining. Because of the circular arc groove chamfering knife, the chip space is large and the cutting is brisk.

Problems solved by technology

[0002] The chamfering knife is a tool that is assembled on the milling machine, drilling machine, planer, chamfering machine and other machine tools to process the 60-degree or 90-degree chamfering and taper hole of the workpiece, and the chamfering tool. The traditional chamfering knife adopts a straight groove. Small chip space and weak tooth back strength cannot adapt to the current high-speed and high-efficiency machining. Because of the circular arc groove chamfering knife, the chip space is large and the cutting is brisk. As a high-end product of the chamfering knife, the demand is increasing However, the processing difficulty of arc grooves is high, especially the final forming grinding, which has been troubled by various manufacturers. Some factories first mill and form, then heat treatment, and finally manually grind the front opening on the tool grinder, and throw it on the grinder. Grooves, and some factories have introduced foreign CNC tool grinding machines, and after heat treatment, the grooves are directly ground on the conical surface, but none of them can achieve the desired effect.

[0003] In the prior art, the grooves are firstly milled and heat-treated, then the tool grinds the front mouth, and the grooves are manually thrown by a grinder. This processing method has poor product precision, high labor intensity for workers, and inconsistent groove shapes. It is difficult to guarantee the size. After quenching, use the outer circle to polish the conical surface and the outer circle of the shank, and then use the CNC tool grinder to directly grind out the arc groove. It can be guaranteed, but the grinding stress is large, the production efficiency is low, and the investment in equipment is also large
