Processing control method for gear lapping machine

Abstract

The invention discloses a processing and control method of gear lapping machine, which comprises the following steps: detecting whether the input data is within the setting scale; setting the lapping parameter; affirming the gear rotary direction; obtaining the feeding speed and lapping parameter of moving side gap value; entering the lapping preparation state; slaving the shaft back side gap; extending the lapping arm; closing the front door; supplying power to the composite pump; starting the lapping circulation subprogram; resetting after lapping; breaking circuit to finish the lapping operation; counting the workpiece. The invention can select the lapping position and lapping speed of each point and loading braking torque of driven wheel freely, which realizes the needed fabricating function as long as the operator inputs or changes the fabricating parameter.

Description

technical field [0001] The invention relates to a gear grinding machine. In particular, it relates to a processing control method for a gear grinding machine that can realize required processing functions by inputting or changing parameters by an operator, and is convenient, flexible, high-precision, and ensures a better contact area. Background technique [0002] The processing method of the existing gear grinding machine can only perform two-point grinding; for example, the feed of the large wheel shaft of the existing 500 series gear grinding machine is driven by a hydraulic cylinder, and the Z axis is installed on the large wheel box. The feeding of the wheel box is driven by a solenoid valve to drive the hydraulic cylinder, which consists of three solenoid valves for the big wheel box to relax, the big wheel box to move forward, and the driven wheel box to retreat, and the driven wheel box to move forward and in place to detect the air valve, and the tooth travel switch...

Problems solved by technology

[0002] The processing method of the existing gear grinding machine can only perform two-point grinding; for example, the feed of the large wheel shaft of the existing 500 series gear grinding machine is driven by a hydraulic cylinder, and the Z axis is installed on the large wheel box. The feeding of the wheel box is driven by a solenoid valve to drive the hydraulic cylinder, which consists of three solenoid valves for the big wheel box to relax, the big wheel box to move forward, and the driven wheel box to retreat, and the driven wheel box to move forward and in place to detect the air valve, and the tooth travel switch. The seven parts of the gapless meshing pneumatic switch and the large tooth and small detection stroke switch are combined. It is very troublesome to adjust the combination of electricity, hydraulic and gas, and it is easy to break down.

Moreover, the loading of the big wheel is driven by a hydraulic proportional valve and an injection motor. The hydraulic proportional valve controls the flow rate, thereby controlling the braking torque. The hydraulic motor controls the direction of the braking torque, which can be forward or reverse. Two directional valves, due to the limitation of the proportional valve, there are only two loading braking torque options for each tooth surface, and the loading braking torque cannot be given by parameters, but can only be given by adjusting the potentiometer, which is inconvenient and Not very accurate, which directly affects the effect of grinding the contact area
