DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: This example is intended to solve the problem in the prior art that, during the long-term use of the equipment, if it is worn for a long time, it will reduce the service life of the equipment, so it is necessary to apply lubricating oil to it. However, the existing application method is mostly to pour the lubricating oil directly on the shaft, which increases the cost of the lubricating oil and causes the problem of lubricating oil waste. Please refer to Figure 1-Figure 4 A device for cutting automobile shaft parts includes a fixed plate 220, a scale 230 is installed in the middle of the fixed plate 220, a workbench 180 is fixedly installed at the end of the fixed plate 220, a motor 400 is fixedly installed at the bottom of the workbench 180, a fixed block 150 is installed on the side of the workbench 180, a fixed cylinder 160 is clamped and connected in the middle of the fixed block 150, a transmission shaft 170 is connected in the middle of the fixed cylinder 160, an extrusion component 390 is provided on the side of the transmission shaft 170, and a cutter head 210 is connected to the side of the transmission shaft 170 through a clamping component 380.

[0023] A mounting rod 120 is installed on the side of the workbench 180, a sliding rod 250 is installed on the side of the mounting rod 120, a clamping rod 260 is slidably connected to the side of the sliding rod 250, a splint 240 is fixedly installed on the side of the clamping rod 260, the middle part of the splint 240 clamps the raw material 110, a transmission block 200 is fixedly connected to the side of the transmission shaft 170, and the middle part of the transmission block 200 is engaged with the connecting block 190 through the engaging assembly 380.

[0024] When the device is in use, the motor 400 is turned on to drive the transmission shaft 170 to rotate, and then the transmission shaft 170 drives the cutter head 210 to transmit, thereby cutting the raw material 110. When parts of different specifications need to be cut, the cutter head 210 can be replaced through the locking assembly 380. During the replacement process, the cutter head 210 is rotated in the opposite direction so that the card slot 330 and the card block 370 in the locking assembly 380 are misaligned, so that the cutter head 210 can be removed and replaced.

[0025] During use, since the transmission shaft 170 rotates for a long time, if it is not lubricated, it may cause equipment failure or reduce the service life of the equipment. During use, through the setting of the extrusion component 390, lubricating oil can be intermittently applied during the rotation of the transmission shaft 170. When the transmission shaft 170 rotates, since the oil beads 320 and the limit plate 310 are both set to rubber material, during use, when the oil beads 320 touch the transmission shaft 170, due to the high-speed rotation of the transmission shaft 170, the oil beads 320 will bounce up due to the limit plate 310. During the bouncing process, the oil rod 280 will be inserted into the oil groove 270, and the lubricating oil will flow into the oil pad 300 along the oil rod 280, and then the oil pad 300 will apply the lubricating oil to the transmission shaft 170 due to the squeezing of the oil beads 320.

[0026] In this embodiment: the cutter head 210 is connected by the locking assembly 380, so that the replacement of the cutter head 210 is faster and the maintenance cost is reduced. The arrangement of the transmission block 200, the connecting block 190 and the locking assembly 380 makes the connection between the drive shaft 170 and the cutter head 210 more secure, reduces the vibration during the cutting process, and improves the cutting quality. The arrangement of the oil beads 320 and the limit rod 140 in the extrusion assembly 390 can achieve intermittent extrusion of the drive shaft 170, which helps lubrication and heat dissipation and extends the service life of the drive shaft 170. The arrangement of the oil groove 270, the oil rod 280 and the oil pad 300 makes the lubrication more uniform, reduces wear and tear, and thus increases the service life of the equipment.

[0027] Example 2: This example is intended to promote the solution of the problem of stable use of the cutter head 210 during the use of the device. This example is an improvement made on the basis of Example 1. For details, please refer to Figure 1-Figure 4 The engaging assembly 380 includes a mounting slot 340 provided in the middle of the transmission block 200 , a connecting spring 350 is provided in the middle of the mounting slot 340 , and a rotating shaft 360 is fixedly installed on the side of the connecting spring 350 .

[0028] A clamping block 370 is hinged on the side of the rotating shaft 360, and a clamping slot 330 is opened in the middle of the connecting block 190. The clamping slot 330 is engaged with the clamping block 370. The extrusion assembly 390 includes an oil outlet bead 320 that is intermittently in contact with the transmission shaft 170. The side of the fixed cylinder 160 is fixedly connected to the limiting rod 140, and the side of the limiting rod 140 is inserted with an oil barrel 130.

[0029] An oil groove 270 is opened in the middle of the limiting rod 140, and an oil outlet rod 280 is inserted in the middle of the oil groove 270. A limiting spring 290 is sleeved on the side of the oil outlet rod 280. An oil pad 300 is fixedly connected to the bottom of the oil outlet rod 280. The oil pad 300 is connected to the oil outlet bead 320. The oil outlet bead 320 is set to a rubber material bead. The side of the oil outlet bead 320 is fixedly connected to the limiting plate 310, and the limiting plate 310 is set to a rubber material plate.

[0030] In this embodiment: the scale 230 in the middle of the fixed plate 220 helps to accurately measure and locate the cutting position, thereby improving the cutting accuracy. The motor 400 fixedly installed at the bottom of the workbench 180 and the fixed block 150, fixed cylinder 160 and other structures on the side make the entire cutting device more stable, which is conducive to improving the cutting quality. The arrangement of the mounting rod 120, the sliding rod 250 and the clamping rod 260 makes it more convenient to clamp and adjust the raw material 110, thereby improving the operating efficiency. The oil beads 320 and the limit plate 310 are made of rubber material with good elasticity and wear resistance, which helps to improve the lubrication effect and reduce noise.

These improvements and modifications should also be regarded as within the scope of protection of the present invention.
