Description

Technical Field

[0001] The present invention relates to the technical field of bearing turning lathes, and particularly to a bearing turning lathe.

Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main functions are to support a rotating mechanical body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. A bearing generally consists of four parts: an inner ring, an outer ring, rolling elements, and a cage. For the processing of the bearing outer ring, a turning lathe is used. The existing turning lathe mainly consists of a transmission channel, a conveyor belt, an electric three-jaw chuck, and a tool holder connected together. By using the electric three-jaw chuck to clamp and rotate the material of the turned bearing outer ring, and then using the movement of the tool holder, the tool holder drives the turning tool into the bearing to drill the inner ring of the bearing. Once the inner ring of the bearing is drilled, the electric three-jaw chuck releases the bearing outer ring, and the bearing outer ring drops into the conveyor belt. The rotation of the conveyor belt drives the bearing outer ring to discharge, thereby completing the processing of the bearing outer ring.

[0003] Although the above solution can process the bearing outer ring, there are still the following problems:

[0004] 1. When drilling the bearing outer ring, iron chips will be generated. These iron chips will fly due to the rotating force. Once the iron chips fly into the conveyor belt and the transmission channel, they will accumulate. Once the iron chips accumulate to a certain extent, it will cause the transmission channel to be blocked, and it is very easy to cause the iron chips to block the conveyor belt and make the conveyor belt unable to rotate normally, thereby indirectly reducing the discharging efficiency of the bearing outer ring.

[0005] 2. When the bearing is being transported, if the transmission channel is blocked by iron chips, it is very easy for the bearing to be unable to discharge normally due to the blockage of the iron chips during the transportation by the conveyor belt, resulting in the failure of the bearing outer ring to discharge.

[0038] Such as Figures 1 to 4, the present invention discloses a bearing turning lathe, including: a lathe body 1, an electric three-jaw chuck one 2 rotatably connected to the lathe body 1 driven, and a discharging member 3 rotatably connected to the lathe body 1 driven, the discharging member 3 is located below the electric three-jaw chuck one 2.

By driving the first lead screw 14 to rotate by the first motor 15 and making the first lead screw 14 drive the first baffle 4 to move, the first baffle 4 is moved to be in contact with the guide plate 11. By using the control panel 13 to control the first motor 15 to stop or turn off, the moving position of the first baffle 4 can be controlled.

[0048] Specifically, since an electric push rod 16 with an output shaft fixedly connected to the electric three-jaw chuck 5 is fixedly connected to the second baffle 9, the electric push rod 16 is electrically connected to the control panel 13, and the electric push rod 16 can push the electric three-jaw chuck 5 to move, thereby realizing the movement of the electric three-jaw chuck 5 to the required position.

[0050] Specifically, a support block 19 is fixedly connected to the second telescopic plate 18. A support rod 20 is fixedly connected to the lathe body 1. The support rod 20 is slidably connected to the support block 19. The support rod 20 and the support block 19 are mainly used to support the second telescopic plate 18.

[0051] Specifically, a conveying plate 21 is obliquely and fixedly connected to the lathe body 1. The conveying plate 21 is located between the sealing plate 8 and the first electric three-jaw chuck 2. The conveying plate 21 is mainly used to guide the dropped outer ring of the bearing.

[0052] Specifically, a collection box 22 with a top groove is fixedly connected to the lathe body 1. A guiding frame 23 is fixedly connected to the top surface of the collection box 22. The guiding frame 23 is conically arranged, and the top surface of the guiding frame 23 is attached to the bottom surface of the collection frame 7 close to the discharge block 10. The guiding frame 23 guides the iron filings into the groove, so as to collect the iron filings and further improve the collection effect of the iron filings.

[0053] Specifically, a sealing door 24 is swingably connected to the collection box 22. A discharge box 25 with a top groove is slidably connected to the collection box 22. When the iron filings enter the discharge box 25, the operator can open the sealing door 24 to take out the discharge box 25 to check the iron filings, which further increases the convenience of iron filing cleaning.

[0054] Principle of the present invention: By moving the first baffle 4 to make it adhere to the guiding plate 11. When the first baffle 4 adheres to the second baffle 9, the electric three-jaw chuck 1 clamps the outer ring of the bearing and rotates, while the electric three-jaw chuck 2 clamps the main drilling rod. By moving the electric three-jaw chuck 2, the drilling rod gradually approaches the outer ring to drill the outer ring. After the outer ring drilling is completed, the iron filings enter the collection box 22. The pusher plate 26 is used to push the iron filings to move to the outside through the discharge block 10 for collection. After the iron filings are collected, the electric three-jaw chuck 1 releases the outer ring of the bearing, and the outer ring of the bearing then falls into the collection box 22. By opening the sealing plate 8, it falls onto the belt from the collection box 22, so as to realize the transmission of the outer ring of the bearing by the belt.
