Wheel cap section chamfering device

A wheel cap section chamfering device, comprising:

• a main frame having a top and a bottom, a secondary frame, a lower servo motor, a key, a bearing seat, a left bearing seat, a left shaft, a left bearing, a first driven friction wheel, a left sleeve, left corner cylinder pressure claws, a left turntable, a left mandrel seat, a left mandrel, a chamfer mill, a tool apron, a feeding platform, a feeding cylinder, guide sleeves, guide posts, a support plate, two guide rails, a compression cylinder, a translation sliding table, an upper servo motor, a driving friction wheel, a right mandrel, a right mandrel seat, a right turntable, right corner cylinder pressure claws, a right sleeve, a second driven friction wheel, a right bearing, a right shaft, a right bearing seat, a station rotating platform, a shaft and a bearing, wherein an output end of the shaft is fixedly connected with the station rotating platform, and a station I system and a station II system are arranged on the station rotating platform;
• the left bearing seat is fixed on the left of the station rotating platform, the left shaft and the left bearing are mounted in the left bearing seat, and the first driven friction wheel is mounted on the left shaft and fixed via the left sleeve;
• the left bearing seat, the left shaft, the left bearing, the first driven friction wheel, and the left sleeve constitute the station I system;
• the right bearing seat is fixed on the right of the station rotating platform, the right shaft and the right bearing are mounted in the right bearing seat, and the second driven friction wheel is mounted on the right shaft and fixed via the right sleeve;
• and the right sleeve, the second friction wheel, the right bearing, the right shaft, the right bearing seat, and the station rotating platform constitute the station II system;
• the support plate and the compression cylinder are mounted at the top of the main frame, the two guide rails are mounted on the support plate, the translation sliding table is mounted on the two guide rails, an output end of the compression cylinder is connected with the translation sliding table, the upper servo motor is mounted below the translation sliding table, and the driving friction wheel is mounted on the shaft at an output end of the upper servo motor;
• the feeding cylinder and the two guide sleeves are mounted on the main frame above the station I system, an output end of the feeding cylinder is connected with the feeding platform, the two guide posts are mounted on the feeding platform, and the feeding cylinder controls the feeding platform to move up and down under the action of the guide posts and the guide sleeves;
• the tool apron is mounted below the feeding platform, the chamfer mill is mounted on the tool apron, and angle scales are distributed on the tool apron, wherein the angles scales provide for adjusting a mounting angle of the chamfer mill;
• and
• a working process of the wheel cap section chamfering device is as follows:
• first, a wheel is put into the station II system, and the right corner cylinder pressure claws clamp the wheel;
• next the lower servo motor is started to drive the station rotating platform to rotate 180° so that the wheel in the station II system is located directly below the chamfer mill;
• then the compression cylinder is started to drive the translation sliding table to move left so that the driving friction wheel contacts the second driven friction wheel;
• then the upper servo motor is started, and the wheel rotates at a low speed under the action of drive of the driving friction wheel;
• next the feeding cylinder is started to drive the chamfer mill to be fed, and the chamfer mill begins removing burrs from chamfers of a cap section of the wheel;
• and finally, chamfering is completed after the wheel continuously rotates one circle, wherein
• when the wheel in the station II system is in a machined state, an operator puts a second wheel to be machined into the station I system;
• after the wheel in the station II system is machined, the compression cylinder and the feeding cylinder are reset, drive of the driving friction wheel is released, and the lower servo motor is started so as to drive the station rotating platform to rotate 180° such that the station I system and the second wheel are located directly below the chamfer mill and the station II system is disposed so as that the wheel can be removed therefrom by the operator.
