Description

Technical Field

[0001] This utility model relates to a bearing cutting device for motor bearing processing, belonging to the field of motor bearing processing technology. Background Technology

[0002] An electric motor bearing is a mechanical component used to support the rotation of an electric motor rotor. It allows the rotor to rotate smoothly inside the stator, reducing friction and wear during rotation. The electric motor bearing bears the weight of the electric motor rotor as well as the radial and axial loads generated during operation due to unbalanced forces, electromagnetic forces, etc. The bearing can reliably support the rotor and ensure that it is in the correct position.

[0003] In the production and processing of motor bearings, a cutting machine is needed to cut the bearing tubes to the required dimensions for subsequent processing. However, current cutting machines do not have a feeding structure for the tubes after cutting, requiring manual pushing and feeding of the cut tubes. This is cumbersome and reduces the cutting speed. To address these issues, we provide a bearing cutting device for motor bearing processing. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a bearing cutting device for motor bearing processing, and the specific technical solution is as follows:

[0005] A bearing cutting device for motor bearing processing includes a cutting table. A support box is fixedly connected to the right side of the cutting table. An electro-hydraulic push rod is fixedly installed on the inner bottom wall of the support box. A lifting block is fixedly installed on the telescopic end of the electro-hydraulic push rod. A rotary motor is fixedly installed on the right side of the lifting block. A drive shaft is fixedly installed on the output end of the rotary motor. A cutting disc is fixedly installed on the left end of the drive shaft. A transmission seat is fixedly connected to the bottom surface of the cutting table. A transmission groove is formed on the upper surface of the transmission seat and the bottom surface of the cutting table. A transmission push plate is slidably connected to the inner wall of the transmission groove. A threaded hole is formed on the right side of the transmission push plate. A transmission screw is threadedly connected to the inner wall of the threaded hole. A reduction motor is fixedly installed on the left side of the transmission seat. The output end of the reduction motor is fixedly installed with the left end of the transmission screw.

[0006] Preferably, two bearing rings are fixedly embedded in the inner wall of the transmission groove, and the inner rings of the two bearing rings are fixedly connected to the outer surface of the transmission lead screw.

[0007] Preferably, the upper surface of the cutting table has two limiting grooves, the inner walls of the two limiting grooves are slidably connected to limiting blocks, and the upper surfaces of the two limiting blocks are fixedly connected to the bottom surface of the transmission push plate.

[0008] Preferably, two electric push rods are fixedly installed on the upper surface of the cutting table, and the telescopic ends of the two electric push rods are fixedly connected to a fixed pressure plate. Two positioning blocks are fixedly connected to the bottom surface of the fixed pressure plate, and an elastic fixing pad is fixedly connected to the bottom surface of the two positioning blocks.

[0009] Preferably, a positioning seat is fixedly connected to the upper surface of the cutting table, and the positioning seat is located below the fixed pressure plate.

[0010] Preferably, a controller is fixedly installed on the front of the support box, and the controller is electrically connected to the electric hydraulic push rod, the rotary motor, the geared motor and the electric push rod respectively through wires.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This bearing cutting equipment for motor bearing processing uses the retraction movement of an electric hydraulic push rod inside the support box, in conjunction with a lifting block, to drive a rotary motor and cutting disc downwards. This allows for downward cutting of the bearing tube above the cutting table. The operation of a reduction motor, along with the cooperation of the transmission screw, threaded hole, and transmission push plate inside the transmission seat, drives the transmission push plate to slide to the right within the transmission groove, thus pushing the bearing tube above the cutting table to the right. This provides a feeding structure for the bearing tube, eliminating the need for manual pushing and feeding of the cut tube, simplifying the cutting process and increasing the cutting speed.

[0020] Please see Figure 1-4 In this utility model, a bearing cutting device for motor bearing processing includes a cutting table 1. A support box 2 is fixedly connected to the right side of the cutting table 1. An electric hydraulic push rod 3 is fixedly installed on the inner bottom wall of the support box 2. A lifting block 4 is fixedly installed at the telescopic end of the electric hydraulic push rod 3. A rotary motor 5 is fixedly installed on the right side of the lifting block 4. A drive shaft 6 is fixedly installed at the output end of the rotary motor 5. A cutting disc 7 is fixedly installed at the left end of the drive shaft 6. A transmission seat 8 is fixedly connected to the bottom surface of the cutting table 1. A transmission groove 22 is formed on the upper surface of the transmission seat 8 and the bottom surface of the cutting table 1. A transmission push plate 10 is slidably connected to the inner wall. A threaded hole 11 is opened on the right side of the transmission push plate 10. A transmission screw 12 is threadedly connected to the inner wall of the threaded hole 11. A reduction motor 9 is fixedly installed on the left side of the transmission seat 8. The output end of the reduction motor 9 is fixedly installed with the left end of the transmission screw 12. Through the operation of the reduction motor 9, and in conjunction with the transmission screw 12, threaded hole 11 and transmission push plate 10 inside the transmission seat 8, the transmission push plate 10 can be driven to slide to the right inside the transmission slide groove 22, thereby pushing the bearing tube above the cutting table 1 to the right, thus forming a feeding structure for the bearing tube.

[0021] Preferably, two bearing rings 13 are fixedly embedded in the inner wall of the transmission groove 22. The inner rings of the two bearing rings 13 are fixedly connected to the outer surface of the transmission screw 12. Two limiting grooves 19 are opened on the upper surface of the cutting table 1. Limiting blocks 20 are slidably connected to the inner walls of the two limiting grooves 19. The upper surfaces of the two limiting blocks 20 are fixedly connected to the bottom surface of the transmission push plate 10. By setting the two bearing rings 13, the transmission screw 12 can be supported, which will make the transmission screw 12 more stable when rotating. By using the cooperation of the limiting grooves 19 and the limiting blocks 20, the transmission push plate 10 can be more stable when sliding left and right, and the phenomenon of rotation of the transmission push plate 10 can be avoided.

[0022] Preferably, two electric push rods 14 are fixedly installed on the upper surface of the cutting table 1. The telescopic ends of the two electric push rods 14 are fixedly connected to a fixed pressure plate 16. Two positioning blocks 17 are fixedly connected to the bottom surface of the fixed pressure plate 16. An elastic fixing pad 18 is fixedly connected to the bottom surface of the two positioning blocks 17. A positioning seat 15 is fixedly connected to the upper surface of the cutting table 1.

The controller 21 is electrically connected to the electric hydraulic push rod 3, the rotary motor 5, the reduction motor 9, and the electric push rods 14 through wires. Through the cooperation of the two electric push rods 14, the fixed pressure plate 16, and the positioning blocks 17 with the positioning seat 15, the bearing tube can be fixed to ensure the stability of the bearing tube during cutting. With the controller 21, the operation of the device can be flexibly controlled.

[0023] The working principle of this utility model is as follows:

[0024] In use, the bearing tube is first placed above the positioning seat 15. Then, the two electric push rods 14 are activated to retract, which moves the fixed pressure plate 16, positioning block 17 and elastic fixing pad 18 downward, firmly pressing and fixing the bearing tube. Next, the electric hydraulic push rod 3 is activated to retract, which moves the lifting block 4 and cutting disc 7 downward. Then, the rotary motor 5 drives the drive shaft 6 and cutting disc 7 to rotate, which will press down and cut the bearing tube. After the bearing tube is cut, the electric push rod 14 is controlled to move the fixed pressure plate 16 upward, which can release the fixing of the bearing tube. Then, the reduction motor 9 is activated, which drives the transmission screw 12 to engage with the threaded hole 11, which will drive the transmission push plate 10 to slide to the right inside the transmission slide groove 22 and push the bearing tube above the cutting table 1 to the right, thus continuously feeding the bearing tube during cutting.
