Description

Technical Field

[0001] This application relates to the field of automatic lathes, and in particular to a CNC automatic lathe for machining shaft-type parts. Background Technology

[0002] To reduce the burden of manpower and improve work efficiency, automatic machine tools are usually used when processing parts. Different automatic lathes have been designed for different types of parts to improve work efficiency.

[0003] The Chinese utility model patent with announcement number CN213729345U discloses a lathe for machining long shaft workpieces, including a bed and a chuck set on the bed for clamping long shaft workpieces. A support frame is set on the bed at a position opposite to the chuck. The support frame consists of a hollow ring and a sliding plate for fixing the ring. The sliding plate is slidably mounted on the lathe guide rail. A servo motor is set inside the bed to control the lateral movement of the sliding plate. Several telescopic pressure rods are set inside the ring.

[0004] According to the existing technology, when processing parts, it is necessary to manually clamp the long shaft into the chuck and the ring body so that the telescopic pressure rod presses the parts together. The material needs to be manually fed during the processing, which not only requires a lot of manpower, but also has relatively low production efficiency. Summary of the Invention

[0005] To facilitate loading onto machine tools and improve their processing efficiency, this application provides a CNC automatic lathe for machining shaft-type parts.

[0006] This application provides a CNC automatic lathe for machining shaft-type parts, which adopts the following technical solution:

[0007] A CNC automatic lathe for machining shaft parts includes a machine body, on which are provided a machining section, a loading section, a conveying section, and an unloading section. The conveying section includes a conveying trough and a conveying assembly for conveying materials. The conveying trough is connected to the machining section. The loading section includes a loading trough with a baffle plate disposed between the loading trough and the conveying trough. A loading block is slidably connected to the end of the loading trough near the baffle plate. A loading cylinder is provided on the machine body. The output shaft of the loading cylinder is connected to the side of the loading block away from the baffle plate. A loading chute is provided on the side of the loading block away from the loading cylinder.

[0008] By adopting the above technical solution, the feeding cylinder works, causing the feeding block to move, thereby pushing the workpiece that falls on the feeding chute out of the feeding chute and into the conveying chute. Then, the conveying assembly transports the workpiece to the processing department to complete the feeding, which is convenient for the staff to operate and improves the production efficiency of the device.

[0009] Optionally, the feeding assembly includes a drive motor, which is fixedly connected to the machine body. The output shaft of the drive motor is provided with a first drive wheel, which is located at the end of the feeding trough away from the processing part. The machine body is provided with a second drive wheel at the end of the feeding trough near the processing part. The first drive wheel and the second drive wheel are fitted with the same drive belt. The drive belt is provided with a drive block, and the drive block is provided with a clamping rod, which allows the workpiece to be connected to the clamping rod.

[0010] By adopting the above technical solution, the clamp rod can be moved along the length of the feeding trough by using the drive motor, the first drive wheel, the second drive wheel and the drive belt, thereby completing the feeding.

[0011] Optionally, the clamping rod includes a clamping groove, in which the workpiece can be clamped. An elastic retaining ring is provided in the clamping groove, which can abut against the outer surface of the workpiece. The machine body is provided with a clamping mechanism that can clamp the pipe at the end of the feeding chute near the second drive wheel.

[0012] By adopting the above technical solution, the workpiece is clamped in the slot and the elastic retaining ring. The elastic retaining ring restricts the displacement of the workpiece in the length direction of the feed chute without restricting the rotation of the workpiece, which facilitates the subsequent processing of the workpiece in the processing department.

[0013] Optionally, the clamping mechanism includes two clamping blocks, which are respectively set on both sides of the feeding chute. Each clamping block is provided with a displacement block and a displacement groove. The two displacement blocks are arranged crosswise and are rotatably connected to the machine body. The machine body is provided with a clamping cylinder, and the output shaft of the clamping cylinder passes through and is slidably connected to the two displacement grooves.

[0014] By adopting the above technical solution, the output shaft of the driving clamping cylinder can move the displacement block, thereby driving the clamping block to clamp or release the workpiece, making it easier for the workpiece to be engaged in the slot or to be released from the slot.

[0015] Optionally, the feeding trough has a waste trough extending through its end near the clamping mechanism, and the machine body has a waste bin corresponding to the waste trough.

[0016] By adopting the above technical solution, after the clamping mechanism clamps the remaining waste material and removes the waste material from the slot, the waste material can enter the waste box along the waste material chute, eliminating the need for manual removal of the waste material and facilitating operation by staff.

[0017] Optionally, the machine body is also equipped with a water cooling mechanism on the side where the processing section is located. The water cooling mechanism includes a water tank, a water pump on the water tank, the water pump inlet connected to the water tank, the water pump outlet connected to a spray pipe, and the water tank is equipped with a water inlet.

[0018] By adopting the above technical solutions, the water cooling mechanism can reduce the possibility of the cutting tools in the machining section overheating during the machining process, improve the tool life, and at the same time reduce the possibility of damage to the machine body and personnel caused by flying debris during the machining process.

[0019] Optionally, the unloading section includes an unloading plate, which is located on the side of the machine body where the processing section is located. The unloading plate is provided with several water passage grooves, and the unloading plate is inclined. The unloading plate is provided with a unloading trough on the side away from the spray pipe.

[0020] By adopting the above technical solution, the processed workpiece can enter the feeding trough along the feeding plate, thereby detaching from the machine body and completing the feeding, which is convenient for the operator.

[0021] Optionally, the unloading section also includes a receiving plate. The receiving plate has a receiving groove on the side away from the unloading plate. The receiving plate is rotatably connected to the machine body. The receiving plate has an unloading gear on the side away from the receiving groove. The machine body is equipped with an unloading cylinder. The output shaft of the unloading cylinder is equipped with an unloading rack. The unloading rack meshes with the unloading gear. The receiving plate with the receiving groove can abut against the unloading plate.

[0022] By adopting the above technical solution, the workpiece gradually enters the receiving groove during processing. After processing is completed, the unloading cylinder drives the unloading rack to move, thereby driving the unloading gear to rotate, which causes the receiving plate to rotate and abut against the unloading plate. The processed workpiece enters the unloading plate from the receiving groove, reducing the possibility of the workpiece falling off the unloading plate during the unloading process.

[0023] Optionally, a collection box is provided at the end of the feeding trough away from the feeding plate. A buffer plate is provided on the collection box. The buffer plate is connected to the feeding trough. A buffer pad is provided at the end of the buffer plate away from the feeding trough. A collection ramp is provided inside the collection box. The two ends of the collection ramp are connected to the buffer plate and the bottom surface of the collection box, respectively. A buffer pad is provided on the inner wall of the collection box on the side away from the buffer plate.

[0024] By adopting the above technical solution.

[0025] Optionally, the machine body is equipped with a fixing rod, and the fixing rod is equipped with several guide plates. The side of the guide plate near the feeding trough can abut against the workpiece.

[0026] By adopting the above technical solution, after the workpiece is placed in the feeding trough, the guide plate can abut against the workpiece, reducing the possibility of workpiece displacement or accumulation.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. The operation of the feeding cylinder causes the feeding block to move, thereby pushing the workpiece that falls on the feeding chute out of the feeding chute and into the conveying chute. The conveying assembly then transports the workpiece to the processing department to complete the feeding process. This facilitates operation by the staff and improves the production efficiency of the equipment.

[0029] 2. During processing, the workpiece gradually enters the receiving groove. After processing is completed, the unloading cylinder drives the unloading rack to move, which in turn drives the unloading gear to rotate. This causes the receiving plate to rotate and abut against the unloading plate. The processed workpiece enters the unloading plate from the receiving groove, reducing the possibility of the workpiece falling off the unloading plate during the unloading process.

[0037] The embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0038] This embodiment provides a CNC automatic lathe for machining shaft-type parts, combined with... Figure 1 and Figure 2The system includes a machine body 1, which has a processing section 2, a loading section 3, a conveying section 4, and a unloading section 5. The loading section 3 includes a loading trough 31, and a fixed rod 7 is fixedly connected to the machine body 1. The fixed rod 7 has several guide plates 71, which can all abut against the workpieces in the loading trough 31. The conveying section 4 includes a conveying trough 41, and the loading trough 31 is located on one side of the conveying trough 41 and fixedly connected to the machine body 1. The machine body 1 has a loading cylinder 34 on the side of the loading trough 31 near the conveying trough 41. A loading block 33 is fixedly connected to the output shaft of the loading cylinder 34. The loading block 33 passes through and is slidably connected to the loading trough 31. The end of the loading block 33 near the loading trough 31 has a loading chute 331, allowing the workpiece to enter. The workpiece is fed into the feeding chute 331, with its higher side flush with the bottom of the feeding trough 31. A baffle 32 is fixedly connected to the end of the feeding trough 31 closest to the conveying trough 41, and a feeding ramp 321 is fixedly connected to the end of the baffle 32 away from the feeding trough 31. The end of the feeding ramp 321 away from the baffle 32 is fixedly connected to the conveying trough 41. A conveying assembly 42 is provided on the conveying trough 41. When the feeding cylinder 34 operates, it lifts the feeding block 33, allowing the workpiece in the feeding chute 331 to pass over the baffle 32 and enter the conveying trough 41 through the feeding ramp 321. Then, the conveying assembly 42 transports the workpiece to the processing section 2, thus completing the feeding process. This facilitates operation by the staff and improves the production efficiency of the device.

[0039] Combination Figure 2 and Figure 3 The feeding assembly 42 includes a drive motor 421. A first drive wheel 425 is fixedly connected to the output shaft of the drive motor 421. The first drive wheel 425 is rotatably connected to the machine body 1. The first drive wheel 425 is located at the end of the feeding trough 41 away from the processing part 2. A second drive wheel 422 is rotatably connected to the end of the machine body 1 near the processing part 2 of the feeding trough 41. The second drive wheel 422 and the first drive wheel 425 are fitted with and connected by the same drive belt 423. A drive block 424 is fixedly connected to the drive belt 423. A locking rod 44 is fixedly connected to the drive block 424. The locking rod 44 is slidably connected to the feeding trough 41. A locking groove 441 is provided at the end of the locking rod 44 away from the drive block 424. An elastic retaining ring 442 is provided in the locking groove 441. The elastic retaining ring 442 can abut against the outer surface of the workpiece. The elastic retaining ring 442 restricts the movement of the workpiece in the length direction of the feeding trough 41, while not restricting the rotation of the workpiece, so that the workpiece can be rotated in subsequent processing.

[0040] Combination Figure 2 and Figure 4The machine body 1 is equipped with a clamping mechanism 43, which includes two displacement blocks 432. Both displacement blocks 432 are rotatably connected to the machine body 1 and are arranged crosswise. The intersection point of the two displacement blocks 432 is the turning point of the two displacement blocks 432. Each of the two displacement blocks 432 has a displacement groove 433. The machine body 1 is equipped with a clamping cylinder 434, the output shaft of which passes through and is slidably connected to the displacement groove 433. A clamping block 431 is fixedly connected to the end of each of the two displacement blocks 432 away from the turning point. The material conveying trough 41 passes through the machine body 1 at the location where the clamping mechanism 43 is located. A waste trough 411 is provided, and a waste bin 412 is provided below the waste trough 411. After the workpiece enters the conveying trough 41, the clamping cylinder 434 drives the displacement block 432 to rotate, so that the clamping block 431 clamps the workpiece, making it easy for the workpiece to be connected to the clamping rod 44. After the workpiece is processed, the clamping rod 44 retracts under the action of the conveying assembly 42, and the clamping cylinder 434 restarts, so that the clamping block 431 clamps the remaining waste of the workpiece, making it easy for the waste to be removed from the clamping rod 44. Then the clamping cylinder 434 drives the clamping block 431 to release the waste, and the waste will enter the waste bin 412 from the waste trough 411, thus completing the collection of waste.

[0041] Combination Figure 1 and Figure 5 The processing unit 2 includes a processing box 21, which is equipped with a receiving pipe 22. The material conveying trough 41 is connected to the receiving pipe 22, and the workpiece can enter the processing box 21 through the receiving pipe 22. The processing box 21 is equipped with several cutting tools and other components (not shown in the figure) for processing the workpiece. The processing box 21 is equipped with a box door 23. The processing box 21 is equipped with a water cooling mechanism 8 for cooling the cutting tools. The water cooling mechanism 8 includes a water tank 81, and a water pump 82 is fixedly connected to the water tank 81. The inlet of the water pump 82 is connected to the water tank 81, and the outlet of the water pump 82 is connected to and fixedly connected to a spray pipe 83. The spray pipe 83 is aimed at the cutting tool. The water tank 81 is equipped with an inlet 84 for receiving the water sprayed from the spray pipe 83. The water cooling mechanism 8 can continuously spray cooling water onto the cutting tool, thereby reducing the possibility of the cutting tool overheating and being damaged. At the same time, it can also reduce the possibility of the device being damaged by flying debris generated when the cutting tool is processing the workpiece.

[0042] The unloading section 5 includes an unloading plate 51 with several water channels 511. The unloading plate 51 is located inside the processing box 21. A receiving plate 53 is rotatably connected inside the processing box 21. The receiving plate 53 has a receiving groove 531 on the side near the spray pipe 83. The processed workpiece enters the receiving groove 531. An unloading gear 54 is fixedly connected to the receiving plate 53. An unloading cylinder 55 is fixedly connected inside the processing box 21. An unloading rack 56 is fixedly connected to the output shaft of the unloading cylinder 55. The unloading gear 54 meshes with the unloading rack 56. The receiving plate 53 has a receiving groove 531 on one side that can abut against the unloading plate 51. The unloading plate 51 has an unloading groove 52 on the side away from the receiving plate 53. The unloading groove 52 is connected to the collection box 6. After the workpiece is processed, it will enter the receiving groove 531. At this time, the unloading cylinder 55 is started, which causes the unloading rack 56 to drive the unloading gear 54 to rotate, thereby driving the receiving plate 53 to rotate. This causes the receiving plate 53 with the receiving groove 531 to abut against the unloading plate 51, so that the workpiece in the receiving groove 531 enters the unloading plate 51 and enters the collection box 6 along the unloading groove 52.

[0043] The material collection box 6 is equipped with a buffer tray 61, which is connected to the discharge trough 52. A material collection ramp 63 is fixedly connected to the side of the buffer tray 61. The side of the material collection ramp 63 away from the buffer tray 61 is fixedly connected to the bottom surface of the material collection box 6. A buffer pad 62 is fixedly connected to the end of the buffer tray 61 away from the discharge trough 52. A buffer layer 64 is fixedly connected to the inner wall of the material collection box 6 on the side away from the buffer tray 61. After the workpiece enters the buffer tray 61 through the discharge trough 52, the buffer pad 62 can absorb part of the impact force of the workpiece impact, reducing the possibility of workpiece damage. After the workpiece enters the material collection box 6 along the material collection ramp 63, the buffer layer 64 can absorb part of the impact force of the workpiece against the inner wall of the material collection box 6, reducing the possibility of workpiece damage. Moreover, through the material collection ramp 63, the workpiece can be neatly stacked in the material collection box 6, making it convenient for workers to take out the processed workpiece.

[0044] Combination Figure 1 and Figure 4 A sensor 9 is fixedly connected to the side of the machine body 1 away from the feeding trough 31 on the side of the feeding trough 41. When the drive block 424 abuts against the sensor 9, the drive motor 421 will stop working, reducing the possibility of the clamping rod 44 entering the processing section 2 and being damaged.

[0045] The method of using this application is as follows: Place the workpiece in the loading groove 31, then start the loading cylinder 34 to move the loading block 33 upward, thereby driving the workpiece in the loading chute 331 to pass over the baffle 32 and enter the loading ramp 321, and then enter the conveying groove 41 through the loading ramp 321. Then start the clamping cylinder 434 to rotate the displacement block 432, thereby causing the clamping block 431 to clamp the workpiece. Then start the drive motor 421 to drive the drive belt 423 to move the drive block 424 toward the workpiece, thereby causing the clamping rod 44 to move toward the workpiece and insert the workpiece into the clamping slot 441, and causing the elastic retaining ring 442 to abut against the outer surface of the workpiece. Then the clamping cylinder 434 drives the displacement block 432 to return to its original position, causing the clamping block 431 to release the workpiece. The drive motor 421 continues to operate to drive the drive block 424 to move the clamping rod 44 toward the processing part 2, thereby causing the clamping rod 44 to drive the workpiece toward the processing part 2 and enter the receiving pipe 22, thus completing the loading.
