Description

Technical Field

[0001] This invention relates to the field of aluminum housing processing technology, specifically a cutting device for stator aluminum housings. Background Technology

[0002] In the manufacturing process of aluminum housings (such as motor housings and instrument protective cases), cylindrical aluminum tubes must first be cut to a fixed length before subsequent stamping, hole-making, and other processing. Existing aluminum tube cutting molds have the following technical defects, which restrict processing quality and efficiency:

[0003] Poor adaptability of internal supports: Traditional mold internal support components are mostly fixed structures, which can only match aluminum cylinders of a single diameter. When dealing with aluminum shell raw materials of different specifications, it is necessary to frequently replace the internal support components, which is cumbersome and increases equipment costs; Difficult to collect debris: Aluminum debris generated during cutting is easily scattered on the surface of the processing table and in the gaps of the equipment, which not only pollutes the working environment, but may also get stuck between sliding parts, causing jamming and affecting processing accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting device for aluminum stator housings to solve the problems mentioned in the background art.

The other end of the connecting rod 9 is... An inner support plate 10 is fixed by welding and fits against the inner wall of the aluminum cylinder. A second motor 40 is fixedly connected to one side of the sliding frame 5 by bolts. The power end of the second motor 40 is fixedly connected to one end of the rotating shaft 6 by a coupling, which drives the aluminum cylinder to rotate and realizes ring cutting. A first lower drain screen 11 is opened at the bottom of the sliding groove 3. A second lower drain screen 12 is opened inside one side of the processing table 1. A recycling box 13 facing the second lower drain screen 12 is fixedly connected to the bottom of the processing table 1 by bolts. An exhaust pipe 16 is connected to the bottom of the second lower drain screen 12 by a flange.

[0023] A shielding frame 27 is bolted to one side of the upper part of the processing table 1, which is directly opposite the second lower mesh 12 to block the flying debris. A hydraulic cylinder 18 is bolted to the upper part of the shielding frame 27, and a lifting frame 19 is bolted to the output end of the hydraulic cylinder 18. A third motor 20 is bolted to one side of the lifting frame 19, and a cutting blade 21 is bolted to the power end of the third motor 20 through the lifting frame 19 and fixed to the flange.

[0024] Side plates 22 are welded to both sides of the upper part of the processing table 1. A first guide rod 25 is welded to the side plates 22. A side lug 26 is slidably connected to the outside of the first guide rod 25. A first threaded rod 24 is rotatably connected to the side plates 22 by a bearing. The other side lug 26 is threaded to the outside of the first threaded rod 24. Both sets of lugs 26 are fixed to both sides of the sliding plate 2 by bolts. A first motor 23 is fixed to the outside of the side plates 22 by bolts. The power end of the first motor 23 is fixedly connected to one end of the first threaded rod 24 by a coupling.

[0025] A first bevel gear 28 is rotatably connected to the middle of the contact plate 7 via a bearing. Four sets of second bevel gears 29 are meshed with the outer side of the first bevel gear 28. A third threaded rod 30 is fixed to the tail of the second bevel gear 29 by welding. The tail of the third threaded rod 30 is rotatably connected to the inner wall of the contact plate 7 via a bearing. A set of third threaded rods 30 penetrates the contact plate 7 and is connected to a rotating cap 32 via a key. A moving block 31 is threaded to the outer side of the third threaded rod 30. The moving block 31 is fixed to the connecting rod 9 by welding.

[0026] Two sets of control grooves 33 are provided on both sides of the sliding groove 3. A second guide rod 35 is fixed inside the control groove 33 by welding.

The spring 39 is sleeved on the outside of the sliding rod 37 and provides elastic cushioning, allowing the sliding frame 5 to move slightly.

[0027] The inside of the recycling bin 13 is fixed with support plates 14 by welding on both sides. The recycling box 15 is slidably connected to the upper part of the support plate 14. The pull-out design is easy to clean. Several sets of ventilation holes 17 are opened at the bottom of the recycling box 15 to ensure negative pressure transmission. The front of the recycling bin 13 is connected to the door by a hinge, which makes it easy to take out the recycling box 15.

[0028] Working principle: When using this invention, according to the inner diameter of the aluminum cylinder to be processed, the rotating cap 32 is manually rotated. The rotating cap 32 drives a set of third threaded rods 30 to rotate. Through the meshing transmission of the first bevel gear 28 and the second bevel gear 29, the other three sets of third threaded rods 30 are driven to rotate synchronously. The moving block 31 on the outside of the third threaded rod 30 moves along the axial direction of the third threaded rod 30, which drives the connecting rod 9 to slide in the connecting groove 8, thereby adjusting the extension length of the inner support plate 10. The aluminum cylinder is then fitted onto the outside of the inner support plate 10 of the two sets of contact plates 7. The rotating cap 32 is then finely adjusted until the inner support plate 10 is tightly attached to the inner wall of the aluminum cylinder. The second threaded rod 34 is then manually rotated. The second threaded rod drives the moving plate 36 to slide along the second guide rod 35, controlling the distance between the two contact plates 7, thereby fixing both sides of the aluminum tube and completing the fixing of the aluminum cylinder.

[0029] Start the first motor 23. The power end of the first motor 23 drives the first threaded rod 24 to rotate through the coupling. Since the first threaded rod 24 is threadedly connected to one side lug 26 and the other side lug 26 slides along the first guide rod 25, the sliding plate 2 moves linearly along the direction between the side plates 22 with the lug 26. The movement direction of the sliding plate 2 is controlled by the forward and reverse rotation of the motor until the position to be cut of the aluminum cylinder is aligned directly below the cutting blade 21. Then, turn off the first motor 23 to complete the positioning.

[0030] Start the suction pipe 16. The outside of the suction pipe 16 is connected to the suction fan. The suction pipe 16 generates negative pressure. The negative pressure is transmitted to the sliding groove 3 area through the second lower screen 12 and the first lower screen 11 to form a debris adsorption channel. Start the second motor 40 and the third motor 20. The second motor 40 drives the rotating shaft 6 and the aluminum cylinder to rotate at a constant speed. The third motor 20 drives the cutting blade 21 to rotate at high speed.

[0031] Start hydraulic cylinder 18, the output end of hydraulic cylinder 18 pushes the lifting frame 19 to descend slowly, the cutting blade 21 gradually contacts the rotating aluminum cylinder, and the ring cutting begins;

[0032] During the cutting process, the aluminum cylinder is subjected to the radial force of the cutting blade 21, which causes the sliding frame 5 to move slightly along the sliding rod 37. The spring 39 is further compressed to create a buffer gap at both ends of the aluminum cylinder and prevent the aluminum cylinder from deforming.

[0033] Under negative pressure, the aluminum shavings generated during cutting fall through the first lower screen 11 into the second lower screen 12, and finally enter the recycling box 15 through the vent 17, thus completing the shavings collection.
