A chip cleaning mechanism 2 is provided inside the lower end of the punching mechanism 5, and a waste tray 8 is provided on the chip cleaning mechanism 2.

[0027] Furthermore, casters 7 are fixedly installed at the four corners of the bottom of the waste box 6, and the fixing mechanism 3 includes a first fixed block 301 and a second fixed block 302. The second fixed block 302 is fixedly installed on the upper surface of the workbench 1, the first fixed block 301 and the second fixed block 302 are fixedly connected, a support plate 307 is fixedly connected to one side of the first fixed block 301, a screw sleeve 303 is fixedly installed inside the first fixed block 301, and a movable block 304 is slidably connected inside the second fixed block 302. The side of the movable block 304 away from the first fixed block 301 is fixedly connected to a limiting block 305, the limiting block 305 is plugged into one end of the spline shaft body 4, and the side of the movable block 304 close to the first fixed block 301 is rotatably connected to a screw rod 306, and the screw rod 306 threadedly penetrates the screw sleeve 303.

[0028] In the present application, the limit block 305 is interference fit with the inside of the spline shaft body 4, and the fixing mechanism 3 is used to limit the spline shaft body 4. When in use, one end of the spline shaft body 4 is plugged into the limit block 305 on one side, and then the screw 306 on the other side is rotated. Through the threaded cooperation between the screw 306 and the screw sleeve 303, one end of the screw 306 drives the movable block 304 and the limit block 305 to move in the direction close to the spline shaft body 4 until the limit block 305 is plugged into the other end of the spline shaft body 4, thereby fixing the spline shaft body 4. Through the above-mentioned arrangement, not only can the spline shaft bodies 4 of different lengths be limited, but also the punching position of the spline shaft body 4 can be changed by adjusting the two screws 306, which makes the operation more flexible and convenient.

The four first guide rods 503 all slide through the upper end of the mounting frame 501, and a drill bit 506 is fixedly installed on the output end of the first motor 505.

[0030] During operation, the first motor 505 is started to drive the drill bit 506 to rotate, and then the hydraulic cylinder 502 is used to drive the first motor 505, the lifting plate 504 and the drill bit 506 to move downward to achieve drilling of the spline shaft. By arranging the first guide rod 503 at the four corners of the lifting plate 504, the stability of the lifting plate 504 can be improved, thereby improving the accuracy of the drilling position of the drill bit 506. The large particles of waste generated by drilling fall from the drop chute 101 into the waste box 6, and the waste chips are recovered through the waste box 6. By arranging casters 7 at the bottom of the waste box 6, the waste box 6 can be easily moved out from the inside of the workbench 1 for easy transfer.

[0031] Furthermore, the chip cleaning mechanism 2 includes a fixed plate 203 and a limiting plate 206. The fixed plate 203 is fixedly mounted on one end of the upper surface of the workbench 1. The limiting plate 206 is fixedly connected to the inner wall of the mounting frame 501. The fixed plate 203 is internally fixedly and slidably connected to the placement frame 204. The waste tray 8 is arranged inside the placement frame 204. An electric push rod 201 is fixedly mounted on one side of the fixed plate 203. The output end of the electric push rod 201 is fixedly connected to one side of the placement frame 204. Second guide rods 202 are slidably penetrated at both ends of the fixed plate 203. One end of the two second guide rods 202 are fixedly connected to the placement frame 204. Two A mounting plate 207 is provided, and a plurality of support shafts 208 are rotatably mounted on the two mounting plates 207. A support frame 205 is fixedly connected to the upper surface of one end of the placement frame 204. A scraper strip 214 is fixedly mounted on one end of the support frame 205. A second motor 212 is fixedly mounted on the lower surface of one end of the support frame 205. A driving wheel 213 is fixedly mounted on the output end of the second motor 212. An electromagnet 209 is fixedly mounted on the lower surface of the lifting plate 504. The electromagnet 209 is sleeved on the outside of the drill bit 506. A protective cover 210 is rotatably sleeved on the outside of the electromagnet 209. A connecting ring 211 is fixedly sleeved on the outer circumference of the protective cover 210, and the connecting ring 211 is abutted against the driving wheel 213.

[0032] In the present application, a chip cleaning mechanism 2 is provided for the spline shaft body 4 which is mainly made of iron material to clean the waste chips. During the drilling process, the electromagnet 209 is energized. When the current passes through the coil of the electromagnet 209, a strong magnetic field is generated. Under the action of the magnetic field of the electromagnet 209, small particles of waste chips are attracted by the magnetic force and adsorbed by the electromagnet 209, thereby effectively avoiding the splashing of small particles of waste chips and improving the effect of waste chip cleaning. By providing a protective cover 210 outside the electromagnet 209, the waste chips can be adsorbed on the protective cover 210, so that the waste chips can fall directly after the electromagnet 209 is powered off, and the electromagnet 209 can be protected to extend the service life of the electromagnet 209. When the drilling is completed, the spline shaft body 4 is Remove it from the fixing mechanism 3, then start the electric push rod 201, and drive the placement rack 204 and the waste tray 8 to move in the direction close to the drill bit 506 through the electric push rod 201, until they move to just below the drill bit 506, so that the driving wheel 213 is pressed against the connecting ring 211, and the scraper bar 214 is attached to the lower surface of the protective cover 210. At this time, the electromagnet 209 is powered off, and small particles of waste chips fall into the waste tray 8. For the waste chips attached to the protective cover 210, the second motor 212 can be started to drive the driving wheel 213 to rotate, and the connecting ring 211 and the protective cover 210 can be driven to rotate slowly through the driving wheel 213. During the rotation of the protective cover 210, the scraper bar 214 scrapes off the remaining waste chips, which can further improve the cleaning and waste recovery effects.

[0033] In the specific setting, there are two groups of limit plates 206, two in each group, which are slidably connected to the upper surface of the waste tray 8 and the lower surface of the placement rack 204 respectively, and cooperate with the two first guide rods 503, which can play a good guiding and limiting role for the placement rack 204 and the waste tray 8, improve the stability of the placement rack 204 and the waste tray 8 during movement, and ensure that the driving wheel 213 and the scraper strip 214 are in good contact with the connecting ring 211 and the lower surface of the protective cover 210 respectively. During the movement of the placement rack 204, the support shaft 208 is driven to rotate. By setting the support shaft 208 and the mounting plate 207, the placement rack 204 and the waste tray 8 can be supported to ensure the smooth movement of the placement rack 204 and the waste tray 8.

[0034] The working principle of this utility model:

[0035] When in use, one end of the spline shaft body 4 is plugged into the limit block 305 on one side, and then the screw rod 306 on the other side is rotated. Through the threaded cooperation between the screw rod 306 and the screw sleeve 303, one end of the screw rod 306 drives the movable block 304 and the limit block 305 to move in the direction close to the spline shaft body 4 until the limit block 305 is plugged into the other end of the spline shaft body 4, thereby fixing the spline shaft body 4. Then the first motor 505 is started to drive the drill bit 506 to rotate, and the hydraulic cylinder 502 is started to drive the first motor 505, the lifting plate 504 and the drill bit 506 to move downward. At the same time, the electromagnet 209 is energized, and the spline shaft is punched through the high-speed rotation of the drill bit 506. The large particles of waste generated by drilling fall from the blanking chute 101 into the waste box 6, and the waste is recovered by the waste box 6. Under the action of the magnetic field of the electromagnet 209, the small particles of waste will be magnetically The scraper 214 is sucked by the electromagnet 209 and the scraper 214 is sucked by the electromagnet 209, so that the small particles of waste are effectively prevented from splashing. The scraper 214 sucked by the electromagnet 209 is cleaned at intervals. When cleaning, the electric push rod 201 is started, and the placement rack 204 and the waste tray 8 are driven by the electric push rod 201 to move in the direction close to the drill bit 506 until they are moved to the bottom of the drill bit 506, so that the driving wheel 213 is pressed against the connecting ring 211, and the scraper bar 214 is attached to the lower surface of the protective cover 210. At this time, the electromagnet 209 is powered off, and the small particles of waste fall into the waste tray 8. For the waste attached to the protective cover 210, the second motor 212 can be started to drive the driving wheel 213 to rotate, and the connecting ring 211 and the protective cover 210 can be driven to rotate slowly by the driving wheel 213. During the rotation of the protective cover 210, the scraper bar 214 scrapes off the remaining waste, which can further improve the cleaning and waste recovery effects.

[0036] In summary: this spline shaft punching device that is convenient for recycling waste, drives the drill bit 506 to rotate through the first motor 505, and the hydraulic cylinder 502 drives the first motor 505, the lifting plate 504 and the drill bit 506 to move downward, so as to realize the punching of the spline shaft. By setting the fixing mechanism 3, the spline shaft body 4 of different lengths can be limited, and the punching position of the spline shaft body 4 can be changed by adjusting the two screws 306. The operation is more flexible and convenient. By setting the electromagnet 209 at the drill bit 506, small particles of waste can be adsorbed during the punching process, thereby improving the effect of waste cleaning. By setting the scraper 214, the waste remaining on the protective cover 210 can be cleaned, further improving the cleaning and waste recycling effects.
