[0023] The working principle and use process of the present invention are as follows: when the high-low rail turning and milling compound machine tool is needed to process a workpiece, the protective door 2 is first pulled to open the lathe 1, and the workpiece to be processed is placed in the loading hopper 34, and the workpiece slides down the loading hopper 34 by its own gravity. In the initial state, the baffle plate 37 blocks the workpiece to prevent it from falling, and the workpiece will be accumulated at the discharge port of the lower hopper 21. Then, the lifting cylinder 38 is started. When the lifting cylinder 38 is lifted, it can push the pusher block 36 to drive the baffle plate 37 to open the inside of the loading hopper 34. The pusher block 36 slides in the lifting groove, and the pusher block 36 has a trapezoidal structure. When it moves upward, the inclined surface will push the workpieces accumulated at the bottom of the charging hopper 34 to slide upward along the surface of the guide block 35. When the lowest end of the inclined surface of the pusher block 36 is flush with the top end of the inclined surface of the guide block 35, the workpiece will roll along the inclined surface of the pusher block 36 to the inclined surface of the guide block 35, and finally enter the V-shaped groove of the material receiving seat 32. There is no need for complicated loading operations, which greatly saves loading time, improves processing efficiency, and reduces labor intensity.

[0024] It is worth noting that: when the workpiece is pushed upward by the pushing block 36, if the workpieces are piled up and multiple workpieces are pushed at the same time, the blocking roller 323 will block the workpiece above to prevent multiple workpieces from sliding into the loading hopper 34 at the same time, and when a single workpiece rolls along the inclined surface of the pushing block 36 to the inclined surface of the guide block 35, the workpiece will squeeze the blocking roller 323, causing it to drive the sliding block 324 to slide in the sliding groove opened inside the loading hopper 34, thereby squeezing the spring 2 325 to deform and generate elastic force, so that the workpiece can roll smoothly to the inside of the receiving seat 32, thereby completing the transfer of the workpiece.

[0025] Furthermore, after the workpiece transfer is completed, the feeding telescopic rod 33 is started, and the feeding telescopic rod 33 drives the feeding bottom plate 31 to drive the material receiving seat 32 and the workpiece loaded therein to move toward the pneumatic three-jaw chuck 413 at the end of the milling head frame 414. When the material receiving seat 32 and the workpiece loaded therein are at the same horizontal height as the pneumatic three-jaw chuck 413 at the end of the milling head frame 414, the feeding telescopic rod 33 is closed, and the lifting cylinder 38 is started to drive the pusher block 36 to move downward. As the pusher block 36 moves downward, the lifting rack 39 also moves, and the transmission gear 310 meshing with the lifting rack 39 starts to rotate, and the transmission shaft 311 fixed inside the transmission gear 310 also rotates accordingly, and the bevel gear pair 312 at one end of the transmission shaft 311 transmits power to the driving shaft 313, and the driving gear 314 on the surface of the driving shaft 313 drives the driven gear 315 to rotate, and the eccentric disk 317 fixed on the top of the driven shaft 316 inside the driven gear 315 starts to rotate, and the eccentric disk 317 During the rotation, the push-pull sleeve rod 319 is driven to move by the hinge rod 318. With the cooperation of the push-pull sleeve rod 319 and the push-pull sleeve 320, the push-pull plate 322 can be pushed to slide inside the material receiving seat 32, and then the workpiece in the V-shaped groove of the material receiving seat 32 is pushed toward the pneumatic three-jaw chuck 413 at the end of the turning and milling head frame 414. When the workpiece is pushed to the inside of the pneumatic three-jaw chuck 413, the pneumatic three-jaw chuck 413 will start automatically to fix the workpiece, and can automatically complete the automatic pushing of the workpiece from the material receiving seat 32 to the pneumatic three-jaw chuck 413. The entire pushing process has a high degree of automation, reduces manual intervention, reduces labor intensity, and avoids errors that may be caused by manual pushing, ensuring that the workpiece can be smoothly and accurately delivered to the processing position, improving the preparation efficiency and accuracy of processing, enabling the machine tool to quickly enter the processing state, reducing the preparation time before processing, thereby improving the overall processing efficiency, and increasing the production capacity and economic benefits of the machine tool.

[0026] It is worth noting that: through the setting of spring 1 321, the push-pull plate 322 can adaptively push the workpiece to move a distance inside the material receiving seat 32, so that workpieces of different lengths can be pushed to the pneumatic three-jaw chuck 413 at the end of the turning and milling head frame 414, and as the lifting cylinder 38 drives the pushing block 36 to move downward, the workpieces subsequently accumulated inside the loading hopper 34 will be stuck between the guide block 35 and the pushing block 36 again. When the lifting cylinder 38 is started again and drives the pushing block 36 to move upward, it will be transported to the inside of the material receiving seat 32 again, and so on.

[0027] Furthermore, after the pneumatic three-jaw chuck 413 at the end of the milling head frame 414 completes the fixation of the workpiece, by starting the screw slide 1 43, its output end drives the milling tail frame 44 to slide on the high and low slide rails 42, and adjusts the position of the milling tail frame 44 so that the pneumatic three-jaw chuck 413 at its end approaches the other end of the workpiece. When the other end of the workpiece is inserted into the pneumatic three-jaw chuck 413 at the end of the milling tail frame 44, the pneumatic three-jaw chuck 413 is started to clamp the workpiece, which greatly improves the stability of the workpiece during machining and effectively prevents the workpiece from being displaced or shaken during machining, ensures machining accuracy, reduces the defective rate, and improves product quality. The high and low slide rails 42 ensure the stability and accuracy of the movement of the milling tail frame 44. After the workpiece is fixed, the position and type of the tool need to be adjusted according to the machining process requirements. By starting the screw slide 2 47, the moving seat 48 is driven to slide on the track 1 on the surface of the support seat 41. The position of the tool in the horizontal direction is thereby adjusted, and then the screw slide 49 is started, thereby pushing the abutment seat 410 to slide on the track 2 on the surface of the moving seat 48, and adjusting the position of the tool in the vertical direction, so that the tool on the turret seat 411 is aligned with the processing part of the workpiece, and the tool changing motor inside the turret seat 411 is started, driving the tool changing disc 412 to rotate, and different specifications of turning and milling tools can be selected for processing according to processing requirements, and the tool on the turret seat 411 can be accurately aligned with the processing part of the workpiece. The flexible and accurate tool adjustment method enables the machine tool to adapt to various complex processing technology requirements and meet processing requirements of different shapes, sizes and precisions. Different specifications of turning and milling tools can be selected for processing according to processing requirements. The automatic tool changing function reduces the time and labor intensity of manual tool changing, improves production efficiency, and also avoids problems such as inaccurate tool installation that may occur during manual tool changing, thereby ensuring the stability of processing quality and improving processing efficiency and production continuity.

[0028] It is worth noting that: through the operation of the screw slide 43, its output end pushes the milling tailstock 44 to slide on the high and low slide rails 42, and adjusts the distance between the milling tailstock 44 and the milling headstock 414, thereby realizing the clamping and positioning of workpieces of different lengths.

[0029] Furthermore, when a workpiece is processed, the pneumatic three-jaw chuck 413 at the end of the milling head frame 414 will release the fixation of the workpiece, and the pneumatic three-jaw chuck 413 at the end of the milling tail frame 44 will still keep the fixation of the workpiece, and then the pneumatic three-jaw chuck 413 at the end of the milling tail frame 44 and the clamped workpiece will move in the direction away from the milling head frame 414 under the action of the screw slide 43, and the pusher frame 45 will move accordingly. When the pusher frame 45 moves to trigger the extrusion switch 46 fixed on the side of the milling tail frame 44 facing the inner wall of the lathe 1, the unloading signal is triggered, and the extrusion switch 46 sends a signal The unloading base plate 51 is controlled to rise to a suitable height under the action of the unloading telescopic rod 52 in the base of the lathe 1, so that the unloading clamp arm 53 is in the position to clamp the workpiece. The precise trigger mechanism ensures that the unloading action is carried out at the right time, avoiding the problems caused by unloading too early or too late, improving the accuracy and reliability of the unloading operation, helping to improve the coordination of the entire processing system, reducing manual intervention, and improving operating efficiency. At the same time, it ensures that the unloading clamp arm 53 can accurately reach the appropriate position every time, providing a guarantee for the smooth clamping of the workpiece and reducing the risk of unloading failure due to inaccurate position.

[0030] Furthermore, by moving the unloading base plate 51 upward, the unloading gear 515 will rotate along the surface of the unloading rack 516, thereby driving the ratchet ring 514 to rotate synchronously. The ratchet ring 514 cooperates with the pawl 512 and the spring three 513 through the internal ratchet groove to drive the fixed plate 511 to rotate. The fixed plate 511 drives the bevel gear pair 2 59 to rotate through the rotating shaft 510, thereby rotating the rotating shaft 56. The rotating shaft 56 then rotates, and the cam 57 fixed on the surface of the rotating shaft 56 rotates accordingly. The two sides of the cam 57 are symmetrically abutted with push wheel seats 58, which are fixed to the surface of the unloading clamp arm 53. The rotation process of the cam 57 The convex part of the contour pushes the push wheel seat 58, so that the unloading clamp arm 53 opens around the hinge point, overcomes the tension of the tension spring 55, and releases the clamp seat 54. When the cam 57 rotates to a specific position, the unloading clamp arm 53 opens to the maximum extent. At this time, the workpiece fixed by the pneumatic three-jaw chuck 413 at the end of the milling tailstock 44 is just located between the clamp seats 54. Then the unloading telescopic rod 52 will close automatically and stop lifting the unloading bottom plate 51. As the unloading bottom plate 51 stops, the unloading gear 515 no longer rotates along the surface of the unloading rack 516, and then the ratchet ring 514 stops rotating and releases the self-locking with the ratchet 512. At this time Under the action of the rebound force of the tension spring 55, the unloading clamp arm 53 will close automatically, thereby driving the clamping seat 54 to clamp the workpiece. After the unloading clamp arm 53 clamps the workpiece, the unloading base plate 51 will drop and reset under the action of the unloading telescopic rod 52, and the workpiece will be transferred to the top of the receiving hopper 517, and then the subsequent workpiece will be automatically pushed and fixed from the receiving seat 32 to the pneumatic three-jaw chuck 413. Then, when the screw slide 43 is started again, the milling tailstock 44 drives the pusher frame 45 to slide on the high and low slide rails 42. When the pusher frame 45 contacts the workpiece clamped by the clamping seat 54, it will push the workpiece out from the inside of the clamping seat 54 and fall into the receiving hopper. In the bucket 517, the workpiece is guided by the receiving hopper 517 and falls into the collecting box 518 to realize the unloading process, and the collection of the processed workpiece is completed. The entire unloading process does not require excessive human intervention, which reduces the labor intensity of the operator, greatly improves the production efficiency, reduces the labor cost, and makes the processing flow of the machine tool smoother and more efficient. The unloading process is efficient and orderly, which reduces the residence time of the workpiece in the unloading process, increases the unloading speed, and helps to improve the overall production efficiency of the machine tool. This not only improves the comfort of work, but also reduces the fatigue and error risks of operators due to repetitive work, and improves the safety and quality of work.

[0031] It is worth noting that after unloading, the machine tool can automatically complete the automatic pushing and fixing of the subsequent workpiece from the receiving base 32 to the pneumatic three-jaw chuck 413, thereby realizing the continuity of the processing process. The continuous processing capability reduces the idle time of the machine tool and improves the utilization rate of the equipment. The automated unloading process reduces the labor intensity of the operators, and the operators do not need to frequently carry and load and unload the workpieces, which not only improves the comfort of work, but also reduces the fatigue and error risks of the operators due to repetitive work, thereby improving the safety and quality of work.
