DETAILED DESCRIPTION

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details.

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] like Figures 1 to 4 A bearing processing and cutting device is shown, comprising a workbench 1, the bottom surface of the workbench 1 is equipped with legs to raise the height of the workbench 1, and the top surface of the workbench 1 is symmetrically provided with placement racks 2 for placing bearing raw material tubes, and the top surfaces of the two placement racks 2 are both provided with semicircular grooves, which can more conveniently place the bearing raw material tubes.

[0027] The top surfaces of the two placement racks 2 are respectively provided with movable blocks 12, and the opposite side surfaces of the two movable blocks 12 are hollowed out. The top surfaces of the two movable blocks 12 are respectively provided with first bolts 13, and the bottom ends of the two first bolts 13 penetrate into the hollow area of ​​the movable blocks 12 and are rotatably connected with pressure plates 14. After the raw material tube is placed on the semicircular groove inner cavity on the top surfaces of the two placement racks 2, the two movable blocks 12 are moved, and the two ends of the raw material tube can enter the hollow area of ​​the two movable blocks 12 respectively. At this time, the first bolts 13 are rotated to allow the first bolts 13 to drive the pressure plate 14 to move downward, so that the pressure plate 14 can be pressed against the raw material tube and continue to move downward to squeeze the raw material tube and clamp the end of the raw material tube. The top surfaces of the two pressure plates 14 are longitudinally fixed with limit rods, and the two limit rods penetrate into the top of the movable block 12, so that the limit rods can limit the movement of the pressure plate 14.

[0028] The top surface of the workbench 1 is laterally provided with a cross plate 3 through a bracket, and the bottom surface of the cross plate 3 is hollowed out. The cross plate 3 is arranged above the workbench 1, and a driving motor 4 is fixedly provided on one side of the cross plate 3. The driving motor 4 can perform forward and reverse rotation. The output end of the driving motor 4 passes through the cross plate 3 and is connected with a threaded shaft 5. The free end of the threaded shaft 5 is rotatably connected to the inner side wall of the cross plate 3, and a moving block 6 is provided on the peripheral thread sleeve of the threaded shaft 5. By turning on the driving motor 4, the driving motor 4 drives the threaded shaft 5 to rotate, so that the threaded shaft 5 can drive the moving block 6 to move, and cooperate with the forward and reverse rotation of the driving motor 4 to make the moving block 6 reciprocate. A sliding rod is provided on the inner side wall of the cross plate 3 and located above the threaded shaft 5. The moving block 6 is slidably sleeved on the peripheral side of the sliding rod to limit the movement of the moving block 6.

[0029] An electric push rod 7 is fixedly provided on one side of the bottom surface of the moving block 6, and a vertical rod 8 is longitudinally provided on the output shaft of the electric push rod 7 and the other side of the bottom surface of the moving block 6. A cutting disk 9 for cutting the bearing raw material tube is provided at the bottom end of the vertical rod 8 connected to the electric push rod 7 through a pin shaft. A motor is provided on one side of the two vertical rods 8, and the output shafts of the two motors pass through the vertical rod 8 and are connected to the pin shaft. A grinding disk 10 for removing burrs is provided at the bottom end of the other vertical rod 8 through a pin shaft. After the area to be cut of the raw material tube is moved below the cutting disk 9 and fixed to the top surface of the placement rack 2, the electric push rod 7 is turned on, and the electric push rod 7 drives the vertical rod 8 and the cutting disk 9 to move downward so that the cutting disk 9 can press against the raw material tube. At this time, the motor is turned on to drive the cutting disk 9 to rotate, and cooperate with the electric push rod 7 to drive the cutting disk 9 to move downward so that the cutting disk 9 can press against the raw material tube. The raw material tube is cut and processed. After the processing is completed, the motor is stopped and the electric push rod 7 is moved in the opposite direction to take the cutting disc 9 out from between the two cut raw material tubes. At this time, the drive motor 4 is turned on to drive the cutting disc 9 and the grinding disc 10 to move through the threaded shaft 5 and the moving block 6. Since the size of the grinding disc 10 is larger than the cutting disc 9, the grinding disc 10 can be moved between the two raw material tubes, and the movable block 12 is moved to drive the raw material tube to move so that the cut surface of the raw material tube can be against the side of the grinding disc 10, and the motor is turned on to drive the grinding disc 10 to rotate, so that the grinding disc 10 can process the burrs on the cut surface, avoiding the problem of easy injury from the burrs on the cut surface during subsequent processing and transportation, thereby reducing the impact on the physical and mental health of the staff at work.

[0030] A vertical plate 17 is longitudinally fixed to one side of the two movable blocks 12, and one side of the two vertical plates 17 is in friction contact with one side of the placement rack 2. A plurality of screw holes 18 are respectively provided on one side of the two vertical plates 17 and one side of the two placement racks 2, and a plurality of screw holes 18 are equidistantly provided on one side of the placement rack 2. The two screw holes 18 aligned with one side of the vertical plate 17 and one side of the placement rack 2 are threadedly connected with a second bolt 19. After the two movable blocks 12 and the two pressing plates 14 clamp and fix the two ends of the raw material tube, the screw hole 18 on one side of the vertical plate 17 will be aligned with one of the screw holes 18 on one side of the placement rack 2. At this time, the second bolt 19 is inserted into the two aligned screw holes 18 to fix the raw material tube in the position of the two placement racks 2, which is convenient for cutting and cleaning of burrs.

[0031] A through slot 11 for the cutting disc 9 to pass through is provided on the top surface of the workbench 1 and between the two placement racks 2. When cutting, the cutting disc 9 can enter the inner cavity of the through slot 11 to complete the cutting of the bearing raw material tube.

[0032] The top surfaces of the two placement racks 2 are symmetrically fixed with slide rails 15, and the bottom surfaces of the two movable blocks 12 are provided with slide grooves 16 that slide with the slide rails 15. When the movable blocks 12 move, the movable blocks 12 will move around the slide rails 15 through the slide grooves 16, so that the slide rails 15 and the slide grooves 16 can not only move the auxiliary movable blocks 12, but also ensure that the movable blocks 12 will always be on the top surface of the placement rack 2.

[0033] Working principle:

[0034] The bearing processing and cutting device places the bearing raw material tube to be cut in the semicircular grooves on the top surfaces of the two placement racks 2, and moves the area to be cut to the bottom of the cutting disk 9. At this time, the movable block 12 is moved to allow the two ends of the raw material tube to enter the hollow area of ​​the movable block 12. At this time, the first bolt 13 is rotated to drive the pressing plate 14 to move downward to clamp and fix the end of the raw material tube. At this time, the electric push rod 7 is turned on to drive the vertical rod 8 and the cutting disk 9 to move downward, so that the cutting disk 9 is against the raw material tube, and the motor is turned on to drive the cutting disk 9 to rotate. At the same time, the raw material tube can be cut in cooperation with the electric push rod 7. After the cutting is completed, the electric push rod 7 drives the vertical rod 8 and the cutting disk 9 to move downward. The cutting disc 9 returns to its original position and the motor stops. At this time, the driving motor 4 is turned on. The driving motor 4 drives the moving block 6 to move through the threaded shaft 5, and the moving block 6 drives the cutting disc 9 and the grinding disc 10 to move through the vertical rod 8, so that the cutting disc 9 is moved out from between the two raw material tubes, and the grinding disc 10 is moved between the two raw material tubes. At this time, the movable block 12 is moved so that the cut surface of the raw material tube can be against the side of the grinding disc 10. At this time, the motor is turned on to drive the grinding disc 10 to rotate, so that the grinding disc 10 can clean the burrs on the end of the raw material tube, avoiding the problem of easy puncture from the burrs on the cutting surface during subsequent processing and transportation, thereby reducing the impact on the physical and mental health of the staff at work.
