Description

Technical Field

[0001] The utility model relates to the technical field of bearing ring production, in particular to a turning device based on bearing ring processing. Background Art

[0002] Bearing rings are an important component of rolling bearings. They play the role of fixing bearings in machinery to prevent axial movement or directional deviation of bearings during operation. When processing bearing rings, corresponding turning lathes are needed to cut their outer wall surfaces. Turning is lathe processing, which is a part of mechanical processing. Lathe processing mainly uses turning tools to turn rotating workpieces. Drills, reamers, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing.

[0003] According to the disclosed patent CN212495418U, a turning device for a bearing ring includes a lathe, the upper top surface of the lathe is fixedly connected to a fixed box, an electric motor is installed on the inner side wall of the fixed box, the output end of the motor is fixedly connected to a screw rod, the other end of the screw rod is engaged and sleeved with a moving rod, the top surface of the moving rod is rotatably connected to a pull rod, the other end of the pull rod is rotatably connected to a telescopic rod, one end of the telescopic rod is fixedly connected to a fixed block, and the other end of the telescopic rod is hinged to a rotating rod, the other end of the rotating rod extends outside the fixed box, and the protruding end of the rotating rod is contacted and connected with a pressure block. The turning device of the bearing ring improves the stability of the bearing ring through the groove and the pressure block, making the turning processing size less likely to deviate, improving the quality of the product, reducing the cost consumption, and eliminating the need for manual cleaning of iron chips, saving time and effort, preventing iron chips from contacting workers, improving the safety factor of workers, and making iron chips cleaning convenient. In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: the mutual operation and cooperation between the groove and the pressure block solves the problem of shaking of the bearing ring during cutting processing. However, in actual use, when the pressure block is used to stop the outer side of the bearing ring, it will hinder the cutting of the bearing ring and cannot drive the bearing ring to rotate and fully perform the cutting processing. Moreover, in actual use, only two sets of pressure blocks are used to stop the outer sides of the cutting blade. During the long-term contact cutting process of the cutting blade, the two sets of pressure blocks cannot provide enough stabilizing force, which easily causes the cutting blade to shake arbitrarily and affects the cutting quality. Therefore, it is necessary to design a new technical solution to solve this problem. Utility Model Content

[0025] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A turning device based on bearing ring processing, see Figures 1 to 4 , an adjustment guide rail 11 is movably installed on the inside of the lathe casing 1, and a cutting head 12 is detachably sleeved on the outside of the adjustment guide rail 11. It is characterized in that a rotating plate 2 is movably installed on the outside of the side of the lathe casing 1, and the rotating plate 2 is fixedly installed with a connecting column 21. A guide turntable 22 is fixedly installed on the side of the connecting column 21. A limiting mechanism is set inside the guide turntable 22. A fixed tube 23 is fixedly installed on the side of the guide turntable 22. An adjustment mechanism is set inside the fixed tube 23. A movable arc plate 27 is movably set on the outside of the fixed tube 23. The number of the movable arc plates 27 is four groups, and the movable arc plates 27 and the adjustment mechanism are connected. The transmission is connected, and a tightening mechanism is provided on the side of the lathe housing 1, and the tightening mechanism is located on the outside of the fixed tube 23. Through the mutual cooperation of the adjustment mechanism and the limit mechanism, the spacing between the four sets of movable arc plates 27 on the outside of the fixed tube 23 is adjusted, thereby ensuring that the movable arc plates 27 can fit and limit the bearing ring to be processed from the inside. While ensuring that the bearing ring to be processed can be stably sleeved on the outside of the fixed tube 23, the labor consumption required for the operator to fix it is reduced, thereby improving the stability of the bearing ring during cutting and the quality of cutting.

[0027] For details, see Figures 1 to 4The adjusting mechanism includes a bidirectional screw rod 25 and a transmission rod 29. Fixed plates 24 are fixedly installed on both sides of the fixed tube 23. Both ends of the bidirectional screw rod 25 are rotatably installed inside the fixed plate 24 through bearings. Transmission sleeves 26 are movably sleeved on the surfaces of both ends of the outer side of the bidirectional screw rod 25. A connecting frame 28 is fixedly installed on both ends of the outer side of each transmission sleeve 26 and the movable arc plate 27, and the two sides of the transmission rod 29 are hinged to the outer side of the connecting frame 28 through a rotating shaft. Under the transmission conversion action of the transmission rod 29 and the rotation transmission action of the bidirectional screw rod 25 on the transmission sleeve 26, it can be ensured that the movable arc plate 27 can be expanded or contracted and moved and adjusted on the outside of the fixed tube 23 as the transmission sleeve 26 moves horizontally.

[0028] For further information, see Figures 1 to 4 A limiting groove 41 is provided on the outside of the fixed tube 23, and the transmission rod 29 is slidably inserted into the limiting groove 41. The limiting groove 41 guides and slides the transmission rod 29 to ensure that when the bidirectional screw rod 25 rotates, the transmission sleeve 26 will not rotate axially and can only move horizontally on the outside of the bidirectional screw rod 25.

[0029] It is worth noting that, see Figures 1 to 4 The limiting mechanism includes a guide groove 3 and a guide block 31. A guide block 31 is fixedly installed on the side of each movable arc plate 27. A guide groove 3 is opened on the side of the guide turntable 22, and the number of guide grooves 3 is the same as the number of movable arc plates 27. The guide block 31 is slidably inserted into the guide groove 3, and the cross-sections of the guide block 31 and the guide groove 3 are both T-shaped. Combined with the guiding sliding action of the guide groove 3 on the guide block 31, the movable arc plate 27 can only move horizontally on the outside of the fixed tube 23 under the push and pull action of the transmission rod 29 without lateral tilting movement, thereby ensuring the stability of the movable arc plate 27 against the bearing ring.

[0030] It is worth noting that see Figures 1 to 4 The clamping mechanism includes a clamping plate 52, a fixed frame 5 is fixedly installed on the outside of the lathe casing 1, and an electric push rod 51 is fixedly installed on the inside of the fixed frame 5. The side of the transmission shaft of the electric push rod 51 is rotatably connected to the outside of the clamping plate 52 through a coupling. The structural action of the electric push rod 51 can provide the clamping plate 52 with a corresponding horizontal movement force, so that the clamping plate 52 can move horizontally on the outside of the fixed tube 23 and perform a clamping and limiting treatment on the side of the fixed tube 23.

[0031] It is worth mentioning that see Figures 1 to 4A servo motor 43 is fixedly installed inside the fixed tube 23, and the side of the servo motor 43 transmission shaft is fixedly connected to the outer side of the bidirectional screw 25 through a coupling. A rotating motor 4 is fixedly installed on the side of the lathe casing 1 away from the fixed frame 5, and the side of the rotating motor 4 transmission shaft is rotatably connected to the rotating plate 2 through a bearing. An anti-slip friction pad 42 is fixedly bonded to the outer surface of each movable arc plate 27. The structural action of the servo motor 43 can provide the power required for forward and reverse rotation of the bidirectional screw 25, and then the position of the movable arc plate 27 can be pushed and pulled.

[0032] During operation, the bearing ring to be cut is sleeved on the outside of the fixed tube 23, and then the servo motor 43 is started to operate, which drives the bidirectional screw rod 25 to rotate synchronously. Combined with the guiding and limiting effect of the limiting slide 41 on the transmission rod 29, when the bidirectional screw rod 25 rotates, the transmission sleeves 26 on both sides of the surface of the bidirectional screw rod 25 can move synchronously horizontally toward each other. Then, the two ends of the transmission rod 29 are respectively hinged to the connecting frame 28 located on the outside of the moving arc plate 27 and the transmission sleeve 26 by the rotating shaft, so that the transmission rod 29 can convert the horizontal movement force of the transmission sleeve 26 into In order to provide the driving force for the movable arc plate 27, the guide block 31 located on the outside of the movable arc plate 27 is slidably installed in the guide groove 3. Under the guiding sliding action of the guide groove 3 on the guide block 31, the movable arc plate 27 can be stretched and moved on the outside of the fixed tube 23, so that the movable arc plate 27 can move outward on the outside of the fixed tube 23, increasing the distance between the movable arc plate 27 and the outside of the fixed tube 23, so that the movable arc plate 27 can fit with the inner wall of the bearing ring from the inside of the bearing ring to be cut, and then the bearing ring is subjected to the movable limit treatment to ensure that the bearing ring is placed on the outside of the fixed tube 23. After the stability is achieved, the electric push rod 51 is started synchronously, and it is operated to drive the clamping plate 52 to move synchronously to the left, until the side of the clamping plate 52 is fully fitted to the outside of the fixed tube 23, the side of the fixed tube 23 is sealed, and the rotating motor 4 is started again to operate and drive the fixed tube 23 and the bearing ring sleeved on its surface to rotate synchronously. At the same time, the adjustment guide rail 11 is started and operated to drive the cutting head 12 to move and adjust the position, so that the cutting head 12 is fitted and in contact with the outer wall of the bearing ring outside the fixed tube 23. As the bearing ring rotates, the cutting head 12 The outer wall of the bearing ring can be cut, and after the processing is completed, the guide rail 11 is adjusted to operate and drive the cutting blade to restore its position. Then, under the reverse driving operation of the electric push rod 51, the clamping plate 52 can be driven to move synchronously to the right and disengage from the outside of the fixed tube 23. Then, the servo motor 43 is controlled to rotate in the opposite direction to drive the bidirectional screw rod 25 to rotate. At the same time, under the transmission action of the transmission rod 29, the movable arc plate 27 is disengaged from the inner wall of the bearing ring. Then, the operator moves the bearing ring that has been cut away from the outside of the fixed tube 23 to complete the cutting processing of the bearing ring.
