Embodiment Construction

[0043] The present invention will be further described below in conjunction with accompanying drawing.

[0044] like figure 1 As shown, the high-efficiency precision ultrasonic broaching device includes a broaching machine body, a grating 22, an ultrasonic broach and a controller. The broaching machine body includes a photoelectric encoder 1, a broaching machine driving motor 2, a bed 3, a bearing 4, a bearing seat 5, a broaching machine guide rail 6, a broaching machine screw 7 and a quick positioning clamping device 8. Two broaching bed guide rails 6 are all fixed on the bed 3. The grating 22 is fixed on one side of the bed 3 . The arrangement direction of the slits on the grating 22 is parallel to the longitudinal direction of the broaching machine guide rail 6 . The bearing block 5 is fixed on one end of the bed 3 . One end of the broaching machine screw 7 and the bearing seat 5 form a rotating pair through the bearing 4 . The broaching machine drive motor 2 is fixed ...

Abstract

The invention discloses an ultrasonic broaching tool, a high-efficiency precise ultrasonic broaching device and a broaching process thereof. An existing broaching tool and an existing broaching machine are not provided with integrated information acquisition devices and are short in service life. The ultrasonic broaching tool comprises an ultrasonic transducer, a detection assembly and a broachingtool body. The detection assembly comprises a detection substrate, a laser transceiving belt, an image sensor, an axial pressure sensor, a first radial pressure sensor and a second radial pressure sensor. The high-efficiency precise ultrasonic broaching device comprises a broaching machine body, an optical grating and the ultrasonic broaching tool. The broaching machine body comprises a broachingmachine drive assembly, a broaching machine body, a broaching machine guide rail and a fast positioning and clamping device. A broaching tool three-directional vibration value, a broaching tool axialtensile force, a broaching tool displacement value, and a workpiece dimension based on an image are measured. Real-time detection data is provided for a working condition feedback loop and a stop control loop of a control system. The service life of the broaching tool can be effectively prolonged.
