The electric slide rail 16 is fixedly installed on the upper end of the workbench 1, which is convenient for automatic feeding and unloading of the sleeve, and both ends can be chamfered at the same time, with high work efficiency;

[0028] A chamfering motor 8 is fixedly installed on the outer end of the chamfering cutter head 2, and plastic bristles 9 are attached to the outer side of the chamfering motor 8. A mounting ring 10 is fixedly installed on the outer end of the plastic bristles 9. A micro electric telescopic rod 11 is fixedly installed on the upper end of the mounting ring 10.

A rectangular frame 18 is fixedly installed on the inner end of the mounting hole 17, and a downward pressure cylinder 19 is fixedly installed on the lower end of the rectangular frame 18. An arc-shaped limiter 20 is fixedly installed on the lower end of the downward pressure cylinder 19, and the arc-shaped limiter 20 is arranged on the upper side of the bracket 3. The fixing frame 12 is symmetrically arranged at the front and rear ends of the workbench 1, and can clean the metal debris and metal wire scraps entangled and adhered to the chamfering cutter head 2, thereby improving the convenience and quality of processing;

[0029] Specific working principle:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the shaft sleeve chamfering device is used, the shaft sleeve that needs to be chamfered is transported to the upper side of the support frame 5 by the feeding conveyor belt 4, and the shaft sleeve stays on the inner side of the arc groove 6. The electric slide rail 16 raises the mounting platform 15 to drive the feeding cylinder 14 to move between the support frame 5 and the support frame 5, so that the bracket 3 moves to the lower side of the shaft sleeve, and the feeding cylinder 14 drives the bracket 3 to move upward to lift the shaft sleeve, and then the mounting platform 15 moves on the upper side of the electric slide rail 16 to move the bracket 3 and the shaft sleeve between the chamfering cutter head 2 and the chamfering cutter head 2, and the two sets of driving cylinders 13 drive the fixing frame 12 to move to the two ends of the shaft sleeve, so that the shaft sleeve is in the center position, and the downward pressure cylinder 19 drives the arc limiter 20 to move downward to clamp and limit the shaft sleeve, and then the chamfering motor 8 drives the chamfering cutter head 2 to rotate, and the chamfering cutter head 2 chamfers the shaft sleeve;

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, after the chamfering is completed, the downward pressure cylinder 19 drives the arc-shaped limiter 20 to move upward, and the mounting platform 15 moves toward the direction of the slope support plate 21 at the outer end of the electric slide rail 16. The bracket 3 lifts the sleeve to the upper side of the slope support plate 21, and the bracket 3 moves downward. The sleeve is supported by the slope support plate 21, and the sleeve rolls along the inclination angle of the upper part of the slope support plate 21 toward the unloading conveyor belt 7, and is transported away by the unloading conveyor belt 7 after rolling to the upper side of the unloading conveyor belt 7. When the metal wire scraps are wound around the chamfering cutter head 2, the micro electric telescopic rod 11 drives the mounting ring 10 Move forward, the mounting ring 10 drives the plastic bristles 9 to move to the outside of the chamfering cutter head 2. Because the plastic bristles 9 are relatively long, the plastic bristles 9 are bent on the outside of the chamfering motor 8. When the plastic bristles 9 are separated from the chamfering motor 8, the plastic bristles 9 are plastically deformed and straightened, and then the micro-electric telescopic rod 11 drives the plastic bristles 9 to move back and forth to clean the chamfering cutter head 2, helping to remove debris on the outside of the chamfering cutter head 2. The above completes a series of operations of the shaft sleeve processing chamfering device. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
