Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brushless motor production, in particular to output shaft end processing equipment for brushless motor production. Background Art
[0002] The brushless DC motor consists of a motor body and a driver, and is a typical mechatronics product. Since the brushless DC motor is operated in an automatic manner, it does not require an additional starting winding on the rotor like a synchronous motor that starts under heavy load under variable frequency speed regulation, nor does it produce oscillation and loss of step when the load changes suddenly.
[0003] The output shaft of the brushless motor is a smooth cylindrical shaft. During the cutting process, in order to reserve sufficient processing allowance, the cutting length is generally slightly longer than the finished product length. Therefore, the allowance at the end needs to be cut off during the production process, and its roughness needs to be guaranteed. The end of the bar also needs to be chamfered. In the existing processing process, the end of the output shaft needs to be cut and chamfered, and the output shaft needs to be measured multiple times during processing to ensure the processing size, and the chamfer width cannot be effectively guaranteed. Therefore, shaft end processing equipment is required to ensure the processing length while achieving rapid chamfering. Utility Model Content

[0012] In a preferred embodiment of the utility model, one end of the handle passes through and extends to the outside of one side of the adjustment seat, the vertical section of the front end of the handle is a square structure, and the vertical section of the rear end is a circular structure. A slide groove that matches the square structure of the front end of the handle is provided on the back of the adjustment seat, and the bottom end of the limit screw passes through and extends to the top inner side of the slide groove on the back of the adjustment seat;
[0013] After rotating the limit knob so that its bottom end is located at the appropriate depth in the slide groove on the surface of the adjustment seat, the lifting distance of the handle to the tool mounting seat can be controlled, so that after the end is effectively cut, the cutting depth of the chamfering edge at the bottom of the tool and the edge of the shaft end can be controlled to ensure the chamfering size.
[0014] In a preferred embodiment of the utility model, the top of the tool is provided with a cutting edge, and the bottom of the tool is provided with a chamfering edge.
[0015] The beneficial effects of the utility model are:
