The movable tail ejector 3 is used as a component for directly ejecting and contacting with a workpiece in tail ejector operation and is arranged at the ejecting action end of the tail ejector shaft 2. Before carrying out tail ejection operation, the tail ejection shaft 2 is driven by a tail ejection driving piece to approach the main shaft chuck 1, and a movable tail ejection 3 positioned on the tail ejection shaft 2 is directly ejected and pressed on a blank workpiece clamped by the main shaft chuck 1. During spinning, the spindle chuck 1 rotates under the driving of a spinning spindle and drives a clamped blank workpiece to rotate, and meanwhile, the movable tail ejector 3 tightly ejected by the spindle chuck 1 and the tail ejector shaft 2 also rotate synchronously.
In a preferred embodiment, the movable tail jack 3 is connected and arranged on one end of the tail jack shaft 2 close to the spindle chuck 1 through a tail jack spring 9, namely, arranged on the jacking action end of the tail jack shaft 2. Furthermore, the movable tail cap 3 is movable in the axial direction relative to the tail cap shaft 2. Thus, when the tail ejecting shaft 2 drives the movable tail ejector 3 to carry out tail ejection, the tail ejector spring 9 is compressed; after the spinning is finished, when the tail ejecting shaft 2 is properly ejected and ejected, the movable tail ejector 3 can still tightly eject the blank workpiece under the elastic action of the compressed tail ejector spring 9.

Specifically, the closing-in portion 401 is located on one side, close to the movable tail top 3, of the tail top elastic moving block 4, the closing-in portion 401 is a cylindrical table portion, and a radial outer surface of the closing-in portion 401 is a closing-in equal-diameter cylindrical surface parallel to the axial direction of the tail top shaft 2; the interference part 402 is located on one side of the tail top elastic moving block 4 departing from the movable tail top 3, the interference part 402 is a step with a top surface facing the movable tail top 3, and the interference part 402 has a conical surface with a diameter gradually increasing along the direction departing from the movable tail top 3.
In a preferred embodiment, a moving block positioning ring 6 is arranged on the tail jack shaft 2 and between the tail jack elastic moving block 4 and the movable tail jack 3.

The movable reset spring 5 is sleeved on the tail jacking shaft 2, one end of the movable reset spring 5 is in action connection with the tail jacking elastic moving block 4, and the other end of the movable reset spring is in action connection with the tail jacking shaft 2.

In a specific embodiment, the mobile return spring 5 is operatively connected to the tail shaft 2 by a spring retaining ring 7. The spring positioning ring 7 is fixedly sleeved on the tail jacking shaft 2, optionally, the spring positioning ring 7 is sleeved on the tail jacking shaft 2 and is locked and fixed through a locking screw 8, one end of the movable reset spring 5 is abutted against the spring positioning ring 7, and the other end of the movable reset spring is abutted against the tail jacking elastic moving block 4.
The blank workpiece 20 is spun by the elastic tail top die of the invention, and the specific processing process is shown in fig. 2-9.
Firstly, spinning operation assembly is carried out, a tail top connecting flange 11 on a transmission connecting end of a tail top shaft 2 is connected with an output end of a tail top driving piece 17, and optionally, the tail top driving piece 17 is a tail top oil cylinder; and the main shaft flange connecting end of the main shaft chuck 1 is in transmission connection with the spinning main shaft through the main shaft flange. Referring to fig. 2, before the spinning process is performed, the spindle chuck 1 is separated from the movable tailstock 3, and the fixed end of the blank workpiece 20 is clamped and placed in the clamping position 101 of the spindle chuck 1. As further shown in fig. 3, the tail ejector driving member 17 drives the tail ejector shaft 2 and the movable tail ejector 3 to move leftward through the tail ejector connecting flange 11 and the tail ejector bearing sleeve 10 until the movable tail ejector 3 presses the blank workpiece 20, and the tail ejector spring 9 in the inner groove 201 is compressed to a minimum working state. At this time, the spinning spindle is started, as shown in fig. 4, the spinning spindle drives the spindle chuck 1, the movable tail top 3 and the tail top shaft 2 to synchronously rotate, the spinning wheel 18 is arranged on the outer side of the blank workpiece 20 and starts to be installed with a set program for spinning. In the closing and spinning process, referring to fig. 5 and 6, when the blank workpiece 20 and the spinning wheel 18 interfere with the interference part of the tail top elastic moving block 4 in the working process, the acting force generated by the interference has a component force along the axial direction, and the tail top elastic moving block 4 will move to the right due to the larger acting force of the interference; meanwhile, under the action of the compressed moving return spring 5, when the blank workpiece 20 and the rotating wheel 18 no longer interfere with the tail ejection elastic moving block 4, the tail ejection elastic moving block 4 will automatically return under the elastic action of the moving return spring 5.
Referring to fig. 7 again, when the blank workpiece 20 is processed to the last closing-in position, since the direction of the processing acting force is substantially in the radial direction along the tail ejecting shaft 2, that is, the direction is perpendicular to the closing-in straight side surface of the closing-in portion 401 of the tail ejecting elastic moving block 4, the tail ejecting elastic moving block 4 will not move any more, and the closing-in portion of the workpiece can be processed according to the specified requirement under the cooperation of the rotating wheel 20 and the closing-in equal-diameter cylindrical surface of the closing-in portion 401. So, close up spinning processing can be accomplished in a tail top operation process, need not to divide the multichannel process to go on, convenient and fast, close up spinning processing is efficient, and stability is good.
And after the spinning closing-in is completed, the spinning wheel is withdrawn. Referring to fig. 8, the tail ejecting driving piece 17 drives the tail ejecting shaft 2 to move rightwards for a proper distance, so that the tail ejecting elastic moving block 4 is separated from the blank workpiece 20. At this time, although the tail jack shaft 2 moves rightwards, the movable tail jack 3 still presses against the blank workpiece 20 under the elastic action of the tail jack spring 9 because the tail jack spring 9 connected between the movable tail jack 3 and the tail jack shaft 2 is still in a compressed state, so that the blank workpiece 20 is still stably held on the spindle chuck 1 without falling. Meanwhile, the edge cutting knife 19 extends into the working position, and burrs are removed from the closing-up part which is just finished by spinning, so that the edge cutting work can be finished at one time after the closing-up spinning processing, and the processing efficiency is further improved.
After trimming is completed, the trimming blade 19 is withdrawn and moved away from the working position. Finally, referring to fig. 9, the tail ejecting driving member 17 continues to drive the tail ejecting shaft 2 to move rightwards, and under the action of friction force generated by the precise clearance fit between the tail ejecting shaft 2 and the movable tail ejector 3, the tail ejecting shaft 2 drives the movable tail ejector 3 to synchronously move rightwards and separate from the blank workpiece 20 until the blank workpiece 20 after spinning is conveniently taken out.
The above embodiments are merely preferred embodiments of the present invention, and the technical solutions of the present invention are described in further detail, but the scope and implementation of the present invention are not limited thereto, and any changes, combinations, deletions, substitutions or modifications that do not depart from the spirit and principle of the present invention are included in the scope of the present invention.
