[0002] CNC lathe is the most common equipment in mechanical processing. It is one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring, etc.

The CNC lathes on the market can already achieve automated processing, but the mechanical arm structure design of the loading and unloading is bulky, inflexible and troublesome to install. When the lathe processes shaft parts, if the shaft parts contain burrs, it will cause processing defects, reduce production quality and increase production costs.

[0032] Specifically, the axial tubes 8 inside the storage box 2 are operated by the numerical control operation panel 6, and the axial tubes 8 are rolled outwards through their own round surface design, slide to the upper end of the first inclined feeding tube 32, and are arranged in sequence at the upper end of the first inclined feeding tube 32. The first inclined feeding tube 32 itself is supported and fixed by the first support plate 31, and the frontmost group of axial tubes 8 stays at the upper end of the pushing block 33. The first electric telescopic rod 34 is started, so that the pushing block 33 moves upward and drags a group of axial tubes 8 to move, and the pushing block 33 moves upward. After moving to a certain height, it becomes parallel to the second inclined feeding pipe 42, and the axial tube 8 at the upper end of the pushing block 33 rolls to the upper end of the second inclined feeding pipe 42. When the pushing block 33 moves, it drives the baffle 35 to move, and the baffle 35 blocks the remaining axial tubes 8 at the rear to prevent the remaining axial tubes 8 from being misplaced or arriving at the designated position in advance. After the pushing block 33 is reset, the baffle 35 staggers the space between the pushing block 33 and the axial tube 8, and the remaining axial tubes 8 continue to roll to the upper end of the pushing block 33 and wait for upward feeding, thereby realizing automatic feeding.

[0033] In this embodiment, the pretreatment mechanism 4 includes a second support plate 41 fixedly connected to the base 1, the upper end of the second support plate 41 is fixedly connected to a second inclined feed pipe 42, the lower end of the second inclined feed pipe 42 near the rear end is fixedly connected to the upper end of the first inclined feed pipe 32 near the front end, the rear end of the second inclined feed pipe 42 is fixedly connected to two groups of symmetrical guide plates 43, the upper end of the second inclined feed pipe 42 is fixedly connected to a support frame 46, a first laser probe 47 is installed on the inner side of the support frame 46 near one side, the upper end of the support frame 46 is fixedly connected to an oil box 48, the lower end of the oil box 48 is installed with a spray head 420, and the two ends of the axial pipe 8 are in contact with the inner wall of the second inclined feed pipe 42.

[0034] Specifically, the second support plate 41 provides support and installation for the second inclined feed pipe 42, the guide plate 43 prevents the axial tube 8 from falling off when being transported to the second inclined feed pipe 42, the first laser probe 47 is used to control the extension and retraction of the second electric telescopic rod 44, the support frame 46 fixes the position of the oil box 48, and the spray head 420 outputs lubricating oil on the surface of the axial tube 8. The two ends of the axial tube 8 fit against the inner wall of the second inclined feed pipe 42 to ensure that the axial tube 8 fits against the inner wall of the second inclined feed pipe 42 and rolls in a straight line to prevent dislocation.

[0035] In this embodiment, a first motor 49 is installed at the upper end of the oil box 48, and a first connecting rod 410 is arranged on the inner side of the oil box 48. The output shaft of the first motor 49 is fixedly connected to the first connecting rod 410, and a first bevel gear 411 is fixedly connected to the outer side of the first connecting rod 410. A blade 419 is fixedly connected to the outer side of the first connecting rod 410 near the lower end, and two groups of symmetrical second bevel gears 412 are meshed on the outer side of the first bevel gear 411. The ends of the two groups of second bevel gears 412 that are away from each other are fixedly connected to the second connecting rod 413. The two groups of second connecting rods 413 are rotationally connected to the oil box 48, and the outer sides of the two groups of second connecting rods 413 are fixedly connected to a rotating plate 424.

[0036] Specifically, the first motor 49, as kinetic energy, drives the first bevel gear 411 to rotate through the first connecting rod 410, and then outputs the kinetic energy through the second bevel gear 412, so that the rotating plate 424 rotates through the second connecting rod 413, and the lubricating oil in the oil box 48 is stirred. The blades 419 disperse the lubricating oil sprayed from the spray head 420 again and evenly drop it on the top of the axial pipe 8. The axial pipe 8 will rotate during grinding, and will continue to roll downward after grinding is completed, so that the outer side of the axial pipe 8 is evenly coated with lubricating oil. The remaining structures can also be contaminated with lubricating oil to avoid equipment aging and promote the working efficiency of the device.

[0037] In this embodiment, the ends of the two groups of second connecting round rods 413 that are far away from each other are fixedly connected with a symmetrical first spur gear 414, the outer side of the first spur gear 414 is rotatably connected with a first chain 415, the inner side of the first chain 415 is rotatably connected with a second spur gear 416, the ends of the two groups of second spur gears 416 that are close to each other are fixedly connected with a third connecting round rod 417, the two groups of third connecting round rods 417 are rotatably connected to the inner side of the second inclined feed pipe 42, the ends of the two groups of third connecting round rods 417 that are close to each other are fixedly connected with a third spur gear 418, and two groups of symmetrical mounting grooves 45 are opened on the inner side of the second inclined feed pipe 42, and the third spur gear 418 is arranged on the inner side of the mounting groove 45.

The mounting groove 45 can install the fourth spur gear 421 and the third spur gear 418, and stagger them with the axial tube 8 to prevent the axial tube 8 from getting stuck and unable to continue downward when rolling.

[0039] In this embodiment, the two groups of third spur gears 418 are respectively meshed and connected with the two groups of fourth spur gears 421, and the outer side of the second inclined feeding tube 42 is fixedly connected with two groups of symmetrical second electric telescopic rods 44.

The ends of the two groups of fourth spur gears 421 that are close to each other are fixedly connected with a conical guide sleeve 422, and the inner sides of the two groups of conical guide sleeves 422 are fixedly connected with a grinding ring 423. The tooth length of the third spur gear 418 is greater than the tooth length of the fourth spur gear 421, and the inner side of the grinding ring 423 fits with the outer wall of the axial tube 8.

[0040] Specifically, the fourth spur gear 421 rotates synchronously with the third spur gear 418, and the first laser probe 47 sends a signal to the second electric telescopic rod 44, so that the two groups of fourth spur gears 421 drive the conical guide sleeve 422 to clamp and fix the axial tube 8. The teeth of the third spur gear 418 are longer than the teeth of the fourth spur gear 421, so as to avoid the misalignment of the third spur gear 418 and the fourth spur gear 421 and maintain normal transmission.

The cylinder 58 controls the height of the mechanical gripper 59, and the second laser probe 525 and the signal receiver 526 cooperate with each other to calibrate the position of the mechanical gripper 59.

[0044] Specifically, after the pressure rod 510 enters the U-shaped hydraulic tube 515, the second magnetic block 519 is adsorbed by the first magnetic block 511 to connect with the first slider 518. The placement plate 512 provides installation space for the buffer box 513. The axial tube 8 enters the buffer box 513 after passing through the second inclined feed pipe 42. The outer side of the axial tube 8 will roll on the upper end of the adsorption pad 514 when entering the buffer box 513 to wipe and absorb excess lubricating oil.

[0046] Specifically, the air cylinder 58 is started to move the mechanical gripper 59 downward, and then the two sets of pressure rods 510 are driven to move downward. The pressure rod 510 enters the U-shaped hydraulic tube 515, and the second magnetic block 519 is adsorbed by the first magnetic block 511 to connect with the first slider 518. The pressure rod 510 continues to press downward, and the first slider 518 slides straight downward in the first slide groove 516 through the first clamping block 517.

[0047] In this embodiment, two groups of symmetrical second slide grooves 524 are opened on the inner side of the U-shaped oil pressure tube 515, and the inner sides of the two groups of second slide grooves 524 are slidably connected with second clamping blocks 521.

The mechanical gripper 59 clamps the axial tube 8 through the incisions at both ends, and then transports the axial tube 8 to the processing production line. The pressure rod 510 is separated from the U-shaped oil pressure tube 515, so that the first slider 518 is pulled out through the second magnetic block 519, and then the lower oil pressure is reset by air pressure. The spring 523 contracts and the return force pulls the second slider 520 back. After the first magnetic block 511 is separated from the U-shaped oil pressure tube 515 and is offset from the second magnetic block 519, the resetting of the material picking mechanism 5 is completed.

[0049] Working principle: when in use, the numerical control operation panel 6 is used for operation, and the axial tube 8 inside the storage box 2 rolls outward through its own round surface design, slides to the upper end of the first inclined feeding tube 32, and is arranged in sequence at the upper end of the first inclined feeding tube 32. The first inclined feeding tube 32 itself is supported and fixed by the first support plate 31. The frontmost group of axial tubes 8 stays at the upper end of the pushing block 33, and the first electric telescopic rod 34 is started to make the pushing block 33 move upward and drag a group of axial tubes 8 to move, and the pushing block 3 After moving to a certain height, the axial tube 8 on the upper end of the push block 33 is parallel to the second inclined feeding tube 42, and the axial tube 8 on the upper end of the push block 33 rolls to the upper end of the second inclined feeding tube 42. When the push block 33 moves, it drives the baffle 35 to move, and the baffle 35 blocks the remaining axial tubes 8 behind to prevent the remaining axial tubes 8 from being misplaced or arriving at the designated position in advance. After the push block 33 is reset, the baffle 35 staggers the space between the push block 33 and the axial tube 8, and the remaining axial tubes 8 continue to roll to the upper end of the push block 33 to wait for upward feeding, thereby realizing automatic feeding;

[0050] After the axial tube 8 enters the second inclined feeding tube 42, it continues to roll and is then scanned by the first laser probe 47. The first laser probe 47 sends a signal to the second electric telescopic rod 44. The two sets of second electric telescopic rods 44 extend the output shaft together and drive the two sets of symmetrical fourth spur gears 421 to approach each other. The axial tube 8 is clamped by the grinding ring 423. The teeth of the fourth spur gear 421 slide with the teeth of the third spur gear 418. However, the teeth of the third spur gear 418 are longer than the teeth of the fourth spur gear 421, so as to avoid misalignment between the third spur gear 418 and the fourth spur gear 421 and maintain normal The two sets of grinding rings 423 clamp the axial pipe 8 together and then start the first motor 49, so that the first connecting rod 410 in the oil box 48 rotates, the first connecting rod 410 drives the first bevel gear 411 to rotate, the first bevel gear 411 drives the second bevel gear 412 to rotate through meshing, the second bevel gear 412 drives the second connecting rod 413 to rotate, the rotating plate 424 outside the second connecting rod 413 rotates synchronously to stir the oil box 48, the second connecting rod 413 drives the first spur gear 414 to rotate, the first spur gear 414 drives the first chain 415 to rotate, and the second connecting rod 413 drives the first spur gear 414 to rotate. The second spur gear 416 rotates, and the second spur gear 416 rotates the third spur gear 418 through the third connecting rod 417. The third spur gear 418 meshes with the fourth spur gear 421, and drives the fourth spur gear 421 to rotate, so that the two sets of grinding rings 423 grind the cuts at both ends of the shaft-shaped pipe 8 to remove burrs. The placement groove 45 can install the fourth spur gear 421 and the third spur gear 418, and stagger with the shaft-shaped pipe 8 to prevent the shaft-shaped pipe 8 from being stuck and unable to continue to move downward when rolling. When the shaft-shaped pipe 8 is ground, the spray head 420 is started, and the first connecting rod 410 rotates. The blades 419 rotate synchronously during operation, and the blades 419 disperse the lubricating oil sprayed from the spray head 420 again and evenly drop it on the top of the shaft-shaped pipe 8. The shaft-shaped pipe 8 will rotate when grinding, and will continue to roll downward after grinding, so that the outer side of the shaft-shaped pipe 8 is evenly coated with lubricating oil, and the remaining structures can also be stained with lubricating oil, so as to avoid equipment aging and promote the working efficiency of the device. After grinding, the second electric telescopic rod 44 is started to shrink the output shaft, and then the conical guide sleeve 422 is staggered with the shaft-shaped pipe 8, and the shaft-shaped pipe 8 continues to roll downward at the upper end of the second inclined feeding pipe 42;

[0051] The axial tube 8 passes through the second inclined feeding pipe 42 and enters the buffer box 513. The outer side of the axial tube 8 rolls on the upper end of the adsorption pad 514 when entering the buffer box 513, wiping and adsorbing excess lubricating oil, and evenly smearing the lubricating oil on the outer side of the axial tube 8, so that the subsequent processing effect is better. The lower end position of the inner side of the buffer box 513 is designed as an inclined surface. The axial tube 8 will roll to the bottom of the buffer box 513 and stop, and the second chain 57 is started. The second chain 57 passes through the sliding block 52 7 slides in the sliding groove 54 and then drives the limit block 55 to slide in the limit groove 53, so that the mounting block 56 moves back and forth. After the laser output by the second laser probe 525 is aligned with the signal receiver 526, the mounting block 56 stops moving, and the cylinder 58 is started to move the mechanical gripper 59 downward, and then drives the two groups of pressure rods 510 to move downward. The pressure rod 510 enters the U-shaped hydraulic pipe 515, and the second magnetic block 519 is attracted by the first magnetic block 511 to connect with the first slider 518. The pressure rod 510 continues to press downward, and the first slider 518 slides straight downward in the first slide groove 516 through the first clamping block 517, so that the oil pressure in the U-shaped oil pressure tube 515 is pressurized to the other outlet. The second slider 520 moves upward through the oil pressure on one side, and slides in the second slide groove 524 through the second clamping block 521 to ensure the fixed position. The spring 523 is pulled open, so that the arc push plate 522 moves upward and drags the axial tube 8 to extend upward, and the axial tube 8 is separated from the buffer box 513. Parallel to the mechanical gripper 59, the mechanical gripper 59 clamps the axial tube 8 through the incisions at both ends, and then transports the axial tube 8 to the processing production line. The pressure rod 510 disengages from the U-shaped oil pressure tube 515 to pull out the first slider 518 through the second magnetic block 519, and then the oil pressure below is reset by air pressure. The spring 523 contracts and the return force pulls the second slider 520 back. After the first magnetic block 511 disengages from the U-shaped oil pressure tube 515 and is offset from the second magnetic block 519, the resetting of the material picking mechanism 5 is completed.
