Grinding machine for gear machining

Abstract

The invention relates to the field of gear machining, in particular to a grinding machine for gear machining. The grinding machine comprises a base, wherein a first motor, and a rotating seat driven by the first motor to rotate are arranged on the base, a swing arm is rotationally connected to the base through a first hinge shaft, a second motor and a grinding wheel driven by the second motor to rotate are arranged on the swing arm, a detection mechanism for detecting the tooth position of a gear workpiece are arranged on the base, an elastic mechanism are further arranged on the base, and theelastic mechanism is connected with the swing arm; and when the detection mechanism detects that the grinding wheel is located at the position where the bottom of a tooth groove of the gear workpieceenters a tooth root part, the elastic mechanism applies force to the swing arm to enable the pressure acting on the gear workpiece by the grinding wheel to be reduced. The grinding wheel of the grinding machine locally relieves the downward pressure at the position where the bottom of the tooth groove enters the tooth root part, so that the grinding wheel is not prone to clamp at the position, and the accident probability of the grinding wheel breakage is reduced; and after the rotating speed of the first motor is increased, the grinding efficiency of the gear workpiece can be improved, and after the rotating speed of the first motor changes, the grinding machine can still play a role in reducing the accident probability.

Description

technical field [0001] The present application relates to the field of gear processing, in particular to a grinding machine for gear processing. Background technique [0002] After the tooth machining of the gear is completed, the edge of the end face of the gear needs to be ground to remove the burrs on the edge of the gear. With the improvement of automation level, grinding machines are often used instead of manual grinding for gears. [0003] The Chinese utility model patent whose authorized notification number is CN206366878U discloses a gear end face grinding device. When the grinding device works, the gear workpiece is placed in the external spline on the support rod, and then the rotating motor is started (the rotating motor can be a low-speed motor ) and the grinder, the rotating motor drives the support plate to rotate, and when the support plate rotates, it drives the support rod to rotate. Since the grinder is connected to the hinge rod through the middle and rea...

Problems solved by technology

For involute gears, the angle between the bottom of the tooth groove and the side wall of the tooth root is close to a right angle. If there is a gap at this position or the burr is too hard, the grinding wheel 22 is easily stuck in this position, causing the grinding wheel 22 to break or fly out.
