A cutting tool 87 is fixed on the tool fixing seat 86.

[0042] The structure of the main box 20 and the rotating clamping head 30 are common structures, which can adopt common structures or can adopt the following structures: Figure 7 In the structure shown, a central through hole 21 is formed in the middle of the main case 20, a guide sleeve 22 is fixed in the middle of the front wall of the main case 20, the inner wall of the guide sleeve 22 is a tapered wall, and the rotary clamping head 30 is composed of two semicircular blocks 31, the outer wall of the semicircular blocks 31 is a tapered wall, the two semicircular blocks 31 are inserted into the guide sleeve 22, the tapered walls of the two semicircular blocks 31 are close to the inner wall of the guide sleeve 22, the front walls of the two semicircular blocks 31 are formed with clamping blocks 32, the middle parts of the two clamping blocks 32 are formed with arc grooves, and the shaft sleeve 100 to be processed corresponds to the two arc grooves;

[0043] The rear ends of the two semicircular blocks 31 are formed with a connecting portion, which is inserted into the central through hole 21, and the outer connecting sleeve 23 is inserted into the central through hole 21. The right end of the outer connecting sleeve 23 is hinged on the connecting portion, and an annular protrusion 231 is formed on the outer wall of the rear part of the outer connecting sleeve 23. The rear part of the outer wall of the annular protrusion 231 is formed with an annular limiting edge 232, and the annular limiting edge 232 is inserted into the limiting annular groove 24 formed on the inner wall of the central through hole 21. An elastic gasket 25 is inserted into the outer connecting sleeve 23, and the edge of the elastic gasket 25 is inserted into the limiting annular groove 24 and clamped between the annular limiting edge 232 and the rear wall of the limiting annular groove 24.

[0044] A liquid inlet channel 26 is formed on the front wall surface of the limiting annular groove 24, and the other end of the liquid inlet channel 26 extends out of the main box 20, which can be connected to the oil pipe connected to the main box 20, and the oil inlet and outlet are controlled by the hydraulic system. Its hydraulic structure is a common structure and will not be described in detail. A sealing ring is clamped between the edge of the annular limiting edge 232 and the inner wall surface of the limiting annular groove 24, and a sealing ring is clamped between the front part of the outer connecting sleeve 23 and the inner side wall of the central through hole 21;

[0045] The main shaft 27 is inserted into the central through hole 21 and is hinged to the main housing 20 through a bearing. A spline shaft portion is formed at the front end of the main shaft 27, and the spline shaft portion is inserted into a spline groove formed at the rear ends of the two connecting parts. There is a gap between the spline protrusion of the spline shaft portion and the spline groove.

[0046] A motor frame is fixed on the rear side wall of the main box 20, and a servo motor 90 is fixed on the motor frame. The output shaft of the servo motor 90 is connected to the rear end of the main shaft 27 through a coupling.

[0047] Working principle: the shaft sleeves 100 to be processed are arranged and placed on the top surface of the inclined bottom rod 61. With the inclined bottom rod 61, they can fall from the discharge port in front of the front end of the inclined bottom rod 61 to the bottom horizontal plate 63. The subsequent shaft sleeves 100 to be processed automatically move forward one position along the inclined bottom rod 61. Then, the rear pusher block 471 pushes the shaft sleeves 100 to be processed into the arc groove 582 and against the blocking portion 582 through the pusher rod of the rear pusher cylinder 47. 81, then, the push rod of the rear push cylinder 47 retracts, at this time, the subsequent to-be-processed shaft sleeve 100 automatically slides onto the bottom horizontal plate 63, and then, through the push rod of the lifting cylinder 52, the to-be-processed shaft sleeve 100 at the arc groove 582 is pushed down and is located at the right side of the two arc grooves between the two clamping blocks 32, at this time, the vertical stop bar 59 also descends together and blocks the to-be-processed shaft sleeve 100 on the bottom horizontal plate 63 and at the front end of the oblique bottom rod 61 to prevent it from sliding down;

[0048] Then, the first push block 564 pushes the shaft sleeve 100 to be processed in the arc groove 582 into between the two clamping blocks 32 through the push rod of the first push cylinder 562, and then, the push rod of the first push cylinder 562 retracts, and then, oil is introduced into the liquid inlet channel 26 to compress the elastic gasket 25, and the outer connecting sleeve 23 moves backward, so that the two semicircular blocks 31 are close to each other, thereby clamping and fixing the shaft sleeve 100 to be processed, and then, the servo motor 90 is operated to realize the rotation of the shaft sleeve 100 to be processed. At this time, the first moving servo motor 1 and the second moving servo motor 2 are operated to make the cutting tool 187 approach the outer ring edge of the shaft sleeve 100 to be processed for milling. After completion, everything returns to its original position, so that the two clamping blocks 32 are separated, and then, the push rod of the push cylinder 43 is pushed, and at the same time, The push rod of the material receiving cylinder 82 pushes the oblique rod portion 84 to pass through the feed side groove 71 and the return side groove 72 formed on the right side plate at the rear end of the oblique guide channel 70 and approach the processed sleeve. Then, the push rod of the pushing cylinder 43 pushes the annular pushing block 45 to push the processed sleeve onto the oblique rod portion 84. Then, the push rod of the material receiving cylinder 82 retracts to place the processed sleeve in the oblique guide channel 70 and between the two side plates. As the push rod of the material receiving cylinder 82 gradually retracts, the oblique rod portion 84 is withdrawn, and the processed sleeve falls onto the arc-shaped bottom plate of the oblique guide channel 70 and is drawn out along the arc-shaped bottom plate. Generally, a material receiving trough or a material receiving frame is provided at the discharge end of the oblique guide channel 70 to collect the processed material. It is a commonly used component and will not be described in detail.

[0049] After one is completed, all parts are returned to their original positions, and the subsequent sleeve 100 to be processed can continue to be fed and processed, which is very convenient.

[0050] Finally, the above implementation modes are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be defined by the claims.
