Abstract

The invention discloses a gear reference circle diameter positioning and detecting device, and belongs to the technical field of gear hobbing machining. The gear reference circle diameter positioning and detecting device comprises a base and an oil cylinder which is rotatably fixed to the base, a piston rod of the oil cylinder is provided with a central through hole, a telescopic rod, a compression spring, an inductance-type measuring head and a disc-shaped spring sheet are sequentially arranged in the central through hole from outside to inside, the telescopic rod comprises a spherical head, a rod body and a connecting rod used for connecting the rod body with the spherical head, the inductance-type measuring head abuts against the disc-shaped spring sheet, and a signal port of the inductance-type measuring head electrically communicates with a signal cable. According to the gear reference circle diameter positioning and detecting device, the axial degree of freedom and the rotating degree of freedom are provided through the rotatable oil cylinder, therefore, the spatial position of a gear can be fully adjusted and measured, and the measuring precision and accuracy can be improved; the structure is extremely simple, the cost is extremely low, measured signals are directly exported to a control system through the signal cable, machining parameters are adjusted through the control system, therefore, automatic precise control can be achieved, the machining efficiency and accuracy can be improved, and the machining cost can be further reduced.

Description

technical field [0001] The invention belongs to the technical field of gear hobbing, and in particular relates to a gear pitch circle diameter positioning and detection device. Background technique [0002] During the processing of the gear hobbing machine tool, due to the thermal deformation of the main body of the machine tool and the wear of the tool, the diameter of the index circle of the processed gear workpiece changes. In order to ensure the processing accuracy, it is often necessary to add an on-machine detection system device to the gear processing machine tool to monitor the size and timely correct the processing parameters during the processing. However, the existing complete detection system has a complex structure and high cost, which increases the manufacturing cost. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a gear pitch circle diameter positioning detection device with simple structure and low co...
