Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to a cutting device for the production of cylindrical roller bearings. Background Technique

[0002] As is well known, during the production process of cylindrical roller bearings, it is necessary to cut the raw materials; as the prior art of the cutting device for the production of cylindrical roller bearings, the Chinese Patent Network discloses a cutting device for the production of cylindrical roller bearings with the publication number of CN219053063U, belonging to the technical field of bearing processing. Among them, it includes a base, and a fixed frame is fixedly connected to the upper surface of the base. A first motor is fixedly connected to the surface of the fixed frame. For this cutting device for the production of cylindrical roller bearings, by setting a third motor, a second threaded rod, a first bevel gear and a clamping plate, when fixing bearing raw material bodies with different diameters, people place the bearing raw material bodies between the clamping plates, and then people control the third motor to operate through a control switch, thereby driving the second threaded rod and the third threaded rod to rotate, and at the same time driving the connecting rods to move towards each other, so as to drive the clamping plates to move towards each other to clamp and fix the bearing raw material bodies, facilitating subsequent cutting, being safer and more stable. Under the action of the third motor, the second threaded rod, the first bevel gear and the clamping plate, it is more convenient for people to fix the bearing raw material bodies, and at the same time improves the safety of the device.

[0029] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a cutting device for the production of cylindrical roller bearings, including: a clamping mechanism 1, an adjusting mechanism 2 and a cutting mechanism 3;

[0030] First of all, in order that after the first motor 12 drives the bi-directional lead screw 14 to rotate clockwise, the two movable plates 15 can move closer to each other on the rod body 13, so that the clamping block 16 can clamp the raw material body 4 of the cylindrical roller bearing. The clamping mechanism 1 includes a base 10. The top of the base 10 is movably connected with a bracket 11. The outside of the bracket 11 is fixedly installed with a first motor 12. The output shaft of the first motor 12 is fixedly connected with a bi-directional lead screw 14. Movable plates 15 are threadedly sleeved on two opposite threads of the bi-directional lead screw 14. A rod body 13 is slidably connected inside the movable plate 15. The rod body 13 is fixedly connected to the inside of the bracket 11. The top of the movable plate 15 is fixedly connected with a clamping block 16; in order to facilitate the stable support of the base 10, legs 19 are evenly and fixedly connected to the bottom of the base 10;

[0031] It should be noted that: when the first motor 12 drives the bi-directional lead screw 14 to rotate counterclockwise, the two movable plates 15 can move away from each other on the rod body 13, so that the clamping block 16 can loosen the clamping of the raw material body 4 of the cylindrical roller bearing;

[0032] Secondly, when it is necessary to adjust the position of the cylindrical roller bearing raw material body 4 after clamping, the bracket 11 can drive the slider 21 to slide in the empty slot 20, so that the rack 22 can move along with the movement of the slider 21. Furthermore, after the bracket 11 drives the cylindrical roller bearing raw material body 4 to move to the designated position, the block 23 can be driven to move by tightening the bolt 25, so that the gear 26 can be engaged with the rack 22 under the action of the block 23, and then the position of the bracket 11 can be fixed. The adjusting mechanism 2 includes an empty slot 20 opened inside the base 10 and a support block 24 fixedly connected to the bottom of the base 10. The inner side wall of the empty slot 20 is slidably connected with a slider 21. The top of the slider 21 is fixedly connected to the bracket 11. The bottom of the slider 21 is fixedly connected with a rack 22. The support block 24 is internally threadedly connected with a bolt 25. One end of the bolt 25 is rotatably connected with a block 23. The top of the block 23 is movably connected to the base 10. A gear 26 is fixedly sleeved on the block 23. In order to facilitate the smooth linear movement of the block 23 under the action of the bolt 25, a sliding slot 27 is opened at the bottom of the base 10, and the inner side wall of the sliding slot 27 is slidably connected with the block 23. In order to facilitate the accurate displacement of the bracket 11, a handle 18 is fixedly connected to the outside of the bracket 11, and a scale ruler 17 is fixedly connected to the top of the base 10.

[0033] Thirdly, after the second motor 32 drives the threaded rod 34 to rotate clockwise or counterclockwise, the plate body 33 can move upward or downward on the vertical rod 30. The cutting mechanism 3 includes a vertical rod 30 fixedly connected to the top of the base 10. The top of the vertical rod 30 is fixedly connected with a top plate 31. A second motor 32 is fixedly installed on the top of the top plate 31. The output shaft of the second motor 32 is fixedly connected with a threaded rod 34. The plate body 33 is threadedly sleeved on the threaded rod 34, and the inside of the plate body 33 is slidably connected with the vertical rod 30. After the third motor 35 drives the cutting knife 37 to rotate through the main shaft 36, the cutting knife 37 can cut the cylindrical roller bearing raw material body 4 under the lifting action of the movable plate 15. A third motor 35 is fixedly installed on one side of the plate body 33. The other side of the plate body 33 is rotatably connected with a main shaft 36. The output shaft of the third motor 35 is fixedly connected with the main shaft 36. One end of the main shaft 36 is detachably connected with a cutting knife 37. In order to reduce the rotation load of the threaded rod 34, the bottom end of the threaded rod 34 is rotatably connected to the base 10.

[0034] Summarize and sort out the working steps of this solution according to the above technical solution: After the first motor 12 drives the bidirectional lead screw 14 to rotate clockwise, the two movable plates 15 can move closer to each other on the rod body 13, so that the clamping blocks 16 can clamp the cylindrical roller bearing raw material body 4. In addition, when it is necessary to adjust the position of the clamped cylindrical roller bearing raw material body 4, the bracket 11 can be driven to drive the slider 21 to slide in the empty groove 20, so that the rack 22 can move along with the movement of the slider 21. Furthermore, when the bracket 11 drives the cylindrical roller bearing raw material body 4 to move to the specified position, the block 23 can be driven to move by tightening the bolt 25, so that the gear 26 can be engaged with the rack 22 under the action of the block 23, and thus the position of the bracket 11 can be fixed; After the second motor 32 drives the threaded rod 34 to rotate clockwise or counterclockwise, the plate body 33 can move up or down on the vertical rod 30, so that after the third motor 35 drives the cutting tool 37 to rotate through the main shaft 36, the cutting tool 37 can cut the cylindrical roller bearing raw material body 4 under the lifting action of the movable plate 15.
