During the upward movement of the circular plate, the rotating disk on the second L-shaped plate is driven to move upward through the transmission of the first L-shaped plate and the second L-shaped plate, so that the rotating disk moves to the middle of the slit of the raw material tube after the cutting is completed, and the cutting end of the raw material after the cutting is completed and fed is quickly deburred through the rotation of the rotating disk. After the processing is completed, it is convenient for positioning of subsequent processing and for protecting the operator during the operation.

[0011] 2) The bearing raw material cutting device is provided with components such as an active conveying roller, a passive conveying roller, and a first motor. When the bearing raw material is put into the machine body from the feeding circular hole, the bearing raw material is passed between the active conveying roller and the passive conveying roller, so that the active conveying roller and the passive conveying roller are against the side wall of the bearing raw material, and the first motor is started to drive the active conveying roller to rotate. During the rotation of the active conveying roller, the bearing raw material is pushed to slide into the machine body through the interaction force between the active conveying roller and the passive conveying roller and the side wall of the bearing raw material. The feeding speed and feeding length of the bearing raw material are effectively controlled by the drive of the first motor, and no manual operation is required, which is convenient for feeding and improves efficiency.

[0013] Furthermore, a push rod motor is fixed on the top of the first U-shaped plate, and an output end of the push rod motor passes through the first U-shaped plate and is fixed to the top side wall of the second U-shaped plate.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that when the active conveying roller and the bearing raw material are pressed against each other for output, the push rod motor pushes the active conveying roller and the side wall of the bearing raw material to press against each other more tightly, forming a force on the bearing raw material, so that during the feeding process, the active conveying roller squeezes the bearing raw material to complete autonomous straightening and feeding positioning, thereby improving the stability of feeding.

Since the threads on both sides of the threaded rod rotate in opposite directions, during the rotation of the threaded rod, the threaded rod and the two clamping plates are engaged with each other, so that the two clamping plates move closer to each other under the action of the guide rod, thereby fixing the bearing raw material and preventing it from shaking during the cutting process, thereby improving the stability of the bearing raw material cutting process.

[0017] Further, the adjustment device is composed of a fourth U-shaped plate, a third motor, a threaded sleeve, a screw, a second fixed rod and a sliding rod, the fourth U-shaped plate is fixed on the inner wall of the operating chamber, the third motor is fixed on the fourth U-shaped plate, the threaded sleeve is fixed on the circular plate, the screw is threadedly connected to the threaded sleeve, one end of the screw is fixed to the output end of the third motor, the second fixed rod is fixed on the circular plate, the sliding rod is slidably connected to the second fixed rod, and the other end of the sliding rod is fixed to the bottom side wall of the fourth U-shaped plate.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that after the bearing raw material is cut, the third motor is driven to drive the screw rod to rotate, and under the mutual meshing transmission action between the screw rod and the threaded sleeve, the second fixed rod is pushed to slide on the sliding rod, further driving the circular plate to move upward, so that the rotating disk on the circular plate moves upward, which is convenient for moving the cutting blade when cleaning the flanging burrs generated after cutting the bearing raw material, avoiding the cutting blade from damaging the cleaning brush on the rotating disk, thereby playing a protective role.

[0019] Furthermore, the driving device is composed of a fourth motor and a rotating rod, the fourth motor is fixed on the side wall of the circular plate, the rotating rod rotates on the side wall connected to the circular plate, one end of the rotating rod is fixed to the cutting blade, and the fourth motor and the rotating rod are connected by a second power connecting device.

[0020] The beneficial effect of adopting the above further solution is that the fourth motor drives the rotating rod to rotate, and the cutting operation of the raw material is performed by the rotation of the cutting blade, which is convenient to implement and easy to operate.

[0021] Furthermore, the second power connecting device is composed of a first sliding plate, a first fixing pin, a first fixing groove and a second spring, the first sliding plate is slidably connected to the side wall of the output end of the fourth motor, the first fixing pin is fixed on the side wall of the first sliding plate, the first fixing groove is opened on the side wall of the rotating rod, and the second spring is sleeved on the side wall of the output end of the fourth motor.

[0022] The beneficial effect of adopting the above-mentioned further scheme is that, through the setting of the second power connection device, when no cutting operation is performed, the first sliding plate is caused to slide through transmission, and during the sliding process of the first sliding plate, the first fixed pin and the first fixed groove on the first sliding plate are separated from each other, and further, the rotating rod is no longer driven to rotate, so that the cutting blade on the rotating rod stops rotating during the burr cleaning process, further reducing the power output of the fourth motor, reducing electricity consumption, and saving resources.

[0023] Further, the first power connecting device is composed of a second sliding plate, a second fixing pin, a second fixing groove, a baffle and a third spring. The second sliding plate is slidably connected to the second rotating shaft. The second fixing pin is fixed on the side wall of the second sliding plate.

The third spring is sleeved on the side wall of the second rotating shaft. One end of the third spring is fixed to the side wall of the second sliding plate, and the other end of the third spring is fixed to the side wall of the baffle.

[0024] The beneficial effect of adopting the above-mentioned further scheme is that, through the setting of the first power connection device, when the deburring operation is not performed, the second sliding plate is driven to slide through the transmission, so that the second fixed pin on the second sliding plate and the second fixed groove on the second rotating shaft are separated from each other, so that the second rotating shaft stops rotating when the cutting operation is performed, thereby reducing the power consumption of the fourth motor and saving resources.

[0025] Furthermore, a transmission device is arranged between the fourth motor and the first rotating shaft, and the transmission device consists of a first pulley, a second pulley and a belt. The first pulley is fixed on the side wall of the output end of the fourth motor, and the second pulley is fixed on the side wall of the first rotating shaft. The first pulley and the second pulley are driven by a belt.

[0026] The beneficial effect of adopting the above further solution is that the first pulley and the second pulley can transmit power through the belt, and there is no need to re-set the power source, thus saving equipment funds.

[0028] The beneficial effect of adopting the above-mentioned further scheme is that in the process of the circular plate moving upward through the adjustment device, the second sliding plate and the second inclined surface are abutted against each other, so that the second sliding plate slides, and the second fixed pin on the second sliding plate is connected to the second fixed groove, so that the second rotating shaft rotates, and in this process, the first sliding plate and the first inclined surface of the transmission plate are abutted against each other, so that the first fixed pin and the first fixed groove on the first sliding plate are separated from each other, and further, the rotating rod is no longer driven to rotate, thereby realizing the mutual switching of power for cutting and burr cleaning, saving resources.

[0029] Furthermore, the material cutting and separating device consists of a strip plate and a third inclined surface, wherein the strip plate is fixed on the first L-shaped plate, and the third inclined surface is opened on the side wall of the strip plate.

[0030] The beneficial effect of adopting the above-mentioned further scheme is that during the upward movement of the circular plate, the third inclined surface on the strip plate is counteracted with the operating box, causing it to slide on the first fixed rod under force, further driving the bearing material after cutting to be separated from the material to be cut, making it easier for the cleaning brush on the rotating disk to enter between the material after cutting and the material to be cut, thereby increasing the space and making it easier to clean the burrs.

[0044] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and the price is also higher. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage. According to the shape of the rolling element, rolling bearings are divided into two categories: ball bearings and roller bearings;

[0060] The specific working process of the present invention is as follows:

[0061] When the bearing raw material is cut, first, the raw material to be cut is placed into the interior of the machine body 1 through the feeding circular hole 2. When the bearing raw material is placed into the interior of the machine body 1 from the feeding circular hole 2, the bearing raw material is passed between the active conveying roller 503 and the passive conveying roller 504, so that the active conveying roller 503 and the passive conveying roller 504 are against the side wall of the bearing raw material, and the first motor 506 is started to drive the active conveying roller 503 to rotate. During the rotation of the active conveying roller 503, the bearing raw material is pushed to slide into the interior of the machine body 1 through the interaction force between the active conveying roller 503 and the passive conveying roller 504 and the side wall of the bearing raw material. The driving of the first motor 506 effectively controls the feeding speed and feeding length of the bearing raw material, does not require manual operation, is convenient for feeding, improves efficiency, and is effective in the active conveying. When the roller 503 and the bearing material are pressed against each other for output, the push rod motor 6 pushes the active conveying roller 503 and the side wall of the bearing material to press against each other more closely, forming a force on the bearing material, so that the active conveying roller 503 squeezes the bearing material during the feeding process to complete the self-alignment and feeding positioning, thereby improving the feeding stability. After the placement is completed, the second motor 1002 is started, and the threaded rod 1005 is driven to rotate by the second motor 1002. Because the two sides of the threaded rod 1005 rotate in opposite directions, during the rotation of the threaded rod 1005, the threaded rod 1005 and the two clamping plates 1003 are meshed and transmitted with each other, so that the two clamping plates 1003 move closer to each other under the action of the guide rod 1004, thereby completing the fixing of the bearing material, so that it does not shake during the cutting process, thereby improving the stability of the bearing material cutting process;

[0062] Then, the fourth motor 1301 drives the rotating rod 1302 to rotate, and the cutting blade 14 rotates to cut the raw material.

[0063] Finally, after the cutting is completed, the third motor 1102 is driven to drive the screw rod 1104 to rotate, and under the mutual meshing transmission action between the screw rod 1104 and the threaded sleeve 1103, the second fixed rod 1106 is pushed to slide on the sliding rod 1105, further driving the circular plate 12 to move upward, so that the rotating disk 20 on the circular plate 12 moves upward, and during the movement of the circular plate 12, the first sliding plate 2501 is caused to slide through the transmission, and during the sliding process of the first sliding plate 2501, the first fixing pin 2502 and the first fixing groove 2503 on the first sliding plate 2501 are separated from each other, and further no longer drives the rotating disk 20 to move upward. The movable rod 1302 rotates to stop the cutting blade 14 on the rotating rod 1302 during the burr cleaning process. At the same time, the second sliding plate 2601 is driven to slide through the transmission to connect the second fixing pin 2602 on the second sliding plate 2601 with the second fixing groove 2603 on the second rotating shaft 19. The second rotating shaft 19 starts to rotate through the transmission device to move the rotating disk 20 to the middle of the slit of the raw material tube after cutting. The cutting end of the raw material after cutting and the feeding is quickly deburred by the rotation of the rotating disk 20. After the processing is completed, it is convenient for positioning for subsequent processing and for protecting the operator during operation.

[0064] In summary: The beneficial effects of the present invention are specifically embodied in

[0065] After the bearing material is cut, the cut end of the feed material is quickly deburred, which is convenient for positioning in subsequent processing and protects the operator during operation. In the process of cutting the bearing material, the bearing material can be squeezed to complete autonomous straightening and feed positioning, avoiding separate straightening operations and improving the efficiency of bearing processing.
