Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a bearing inner ring raceway turning device. Background Technology

[0002] In the field of mechanical manufacturing, bearings, as key components supporting rotating shafts, directly affect the operational accuracy, stability, and service life of the entire mechanical system. The bearing inner ring raceway is the crucial part where the inner ring contacts the rolling elements and achieves relative motion. During its machining, a turning device is used for grinding, and coolant is used for cooling. Currently, the coolant is kept constantly on during machining. Therefore, when changing the inner ring that needs machining, although no machining is being performed, the coolant is still being sprayed, resulting in coolant waste. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to propose a bearing inner ring raceway turning device to solve the problem that the coolant is in a constantly open state during the current machining process, so that the coolant is sprayed when changing the inner ring to be machined, resulting in coolant waste.

[0004] To achieve the above objectives, this utility model provides a bearing inner ring raceway turning device, including a frame, and further comprising: a feeding mechanism disposed on one side of the frame for placing the inner ring, a turning mechanism disposed on the other side of the frame, a transfer clamping mechanism for transferring and clamping the inner ring, and a cooling mechanism for cooling the inner ring during machining, wherein: The transfer clamping mechanism includes a track disposed on the rear side of the feeding mechanism, a movable component slidably disposed on the track, a first driving mechanism for driving the movable component to move, a first electric cylinder disposed on the top of the movable component, a mounting plate slidably disposed on the top of the movable component and connected to the telescopic rod of the first electric cylinder, a first motor disposed on the top of the mounting plate, and a clamping unit disposed on the rotating shaft of the first motor. The cooling mechanism includes a switch button located on one side of the track for controlling the start and stop of the cooling mechanism. When the moving part moves to the processing position, the moving part presses the switch button, and the cooling mechanism starts working. When the moving part leaves the processing position, the moving part releases the switch button, and the cooling mechanism stops working.

[0005] Optionally, the feeding mechanism includes a feeding box disposed on one side of the top of the frame, the top of the feeding box having an inclined feeding trough, the span of the feeding trough being greater than the thickness of the inner ring.

[0006] Optionally, the turning mechanism includes a mounting bracket slidably disposed on the other side of the frame, a second motor disposed on the top of the mounting bracket, a turning disc disposed on the rotating shaft of the second motor, and a second drive mechanism for driving the mounting bracket to move.

[0007] Optionally, the second drive mechanism includes a second electric cylinder disposed on the top of the frame, the telescopic rod of the second electric cylinder being connected to one side of the mounting bracket.

[0008] Optionally, the cooling mechanism includes a cooling tank for holding coolant, a pipe installed on the cooling tank, a nozzle installed at one end of the pipe, a pump body connected in series with the pipe, and a switch button electrically connected to the pump body for controlling the start and stop of the pump body.

[0009] Optionally, the clamping unit includes a slot frame fixedly mounted on the rotating shaft of the first motor, a bidirectional threaded rod rotatably connected to the slot frame, two clamping members threadedly connected to the bidirectional threaded rod, and one end of the two clamping members slidably connected in the slot frame.

[0010] Optionally, the clamping member has an elastic pad at one end for clamping the inner ring.

[0011] The elastic pad effectively prevents the inner ring from slipping and loosening during clamping, ensuring clamping stability. Simultaneously, the elastic pad also acts as a buffer, reducing damage to the inner ring surface from the clamping components and improving product quality.

[0012] Optionally, the bottom of the movable component is provided with two sets of sliding grooves, which are respectively used to cooperate with the two sides of the track.

[0013] When the bearing inner ring raceway turning device is working, the unloading mechanism is used to place the bearing inner ring, the transfer clamping mechanism starts to operate, the first drive mechanism drives the moving part to move along the track, after moving to the appropriate position, the first electric cylinder pushes the mounting plate to slide on the top of the moving part, driving the first motor and clamping unit to move to the inner ring, and can be manually operated to clamp the inner ring with the clamping unit. Then the moving part moves to transfer the inner ring to the machining position. When the moving part moves to the machining position, the switch button set on the side of the track for controlling the start and stop of the cooling mechanism is pressed, the cooling mechanism starts to work and cools the inner ring being processed. The turning mechanism performs raceway turning on the clamped inner ring in the machining position. During processing, the first motor drives the inner ring to rotate. After processing is completed, the moving part leaves the machining position, the switch button is released, and the cooling mechanism stops working.

[0014] As can be seen from the above, this utility model, through the linkage between the cooling mechanism and the moving parts, automatically starts and stops according to the processing position, which not only ensures the cooling effect during the processing, but also avoids the waste of coolant and reduces production costs.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1 and Figure 2 As shown, a bearing inner ring raceway turning apparatus includes a frame 1, and further includes: a feeding mechanism disposed on one side of the frame 1 for placing the inner ring 18, a turning mechanism disposed on the other side of the frame 1, a transfer clamping mechanism for transferring and clamping the inner ring 18, and a cooling mechanism for cooling the inner ring 18 during machining, wherein: The transfer clamping mechanism includes a track 2 disposed on the rear side of the feeding mechanism, a movable part 3 slidably disposed on the track 2, a first driving mechanism for driving the movable part 3 to move, a first electric cylinder 4 disposed on the top of the movable part 3, a mounting plate 5 slidably disposed on the top of the movable part 3 and connected to the telescopic rod of the first electric cylinder 4, a first motor 6 disposed on the top of the mounting plate 5, and a clamping unit disposed on the rotating shaft of the first motor 6. The cooling mechanism includes a switch button 7 located on one side of the track 2 for controlling the start and stop of the cooling mechanism. When the moving part 3 moves to the processing position, the moving part 3 presses the switch button 7, and the cooling mechanism starts to work. When the moving part 3 leaves the processing position, the moving part 3 releases the switch button 7, and the cooling mechanism stops working.

[0021] When the moving part 3 moves to the processing position and the switch button 7 is pressed, the switch button 7 controls the pump to start. The pump delivers coolant from the cooling tank through pipes to the nozzle 13, which sprays the coolant onto the inner ring 18 of the bearing being processed, thus cooling it. When the moving part 3 leaves the processing position and the switch button 7 is released, the pump stops working, and the coolant delivery stops. This cooling mechanism has a simple structure, achieving coolant delivery and spraying through the pump and pipes. The linkage between the moving part 3 and the pump's start / stop control ensures effective cooling during processing while preventing coolant waste.

[0022] When the bearing inner ring 18 raceway turning device is working, the unloading mechanism is used to place the bearing inner ring 18, the transfer clamping mechanism starts to operate, the first drive mechanism drives the moving part 3 to move along the track 2, after moving to the appropriate position, the first electric cylinder 4 pushes the mounting plate 5 to slide on the top of the moving part 3, driving the first motor 6 and the clamping unit to move to the inner ring 18, and can be manually operated to clamp the inner ring 18 against the clamping unit. Then the moving part 3 moves to transfer the inner ring 18 to the processing position. When the moving part 3 moves to the processing position, the switch button 7 set on the side of the track 2 for controlling the start and stop of the cooling mechanism is pressed, the cooling mechanism starts to work and cools the inner ring 18 being processed. The turning mechanism performs raceway turning on the clamped inner ring 18 in the processing position. During processing, the first motor 6 drives the inner ring 18 to rotate. After processing is completed, the moving part 3 leaves the processing position, the switch button 7 is released, and the cooling mechanism stops working.

[0023] As can be seen from the above, this utility model, through the linkage between the cooling mechanism and the moving part 3, automatically starts and stops according to the processing position, which not only ensures the cooling effect during the processing, but also avoids the waste of coolant and reduces production costs.

[0024] like Figure 1 As shown, in some embodiments, the feeding mechanism includes a feeding box 8 disposed on one side of the top of the frame 1, the top of the feeding box 8 having an inclined feeding groove, the span of the feeding groove being greater than the thickness of the inner ring 18.

[0025] The bearing inner ring 18 is placed in the feeding slot at the top of the feeding box 8. Due to the inclined design of the feeding slot and its span being greater than the thickness of the inner ring 18, the inner ring 18 will be neatly arranged in the feeding slot under the action of gravity, facilitating the transfer and clamping mechanism to pick it up. The inclined design and appropriate span of the feeding slot enable the inner ring 18 to automatically and orderly arrange itself, facilitating material retrieval, improving the efficiency of feeding and retrieval, and ensuring the accuracy of material retrieval, thus providing convenience for subsequent processing.

[0026] like Figure 3 As shown, in some embodiments, the turning mechanism includes a mounting bracket 9 slidably disposed on the other side of the frame 1, a second motor 10 disposed on the top of the mounting bracket 9, a turning disc 11 disposed on the rotating shaft of the second motor 10, and a second drive mechanism for driving the mounting bracket 9 to move. Optionally, the second drive mechanism includes a second electric cylinder 12 disposed on the top of the frame 1, the telescopic rod of the second electric cylinder 12 being connected to one side of the mounting bracket 9.

[0027] During processing, the second drive mechanism drives the mounting frame 9 to move, so that the mounting frame 9 drives the second motor 10 and the grinding disc 11 to the appropriate processing position. The second motor 10 starts, and its rotating shaft drives the grinding disc 11 to rotate at high speed to process the raceway of the bearing inner ring 18 held on the transfer clamping mechanism.

[0028] like Figure 1 As shown, in some embodiments, the cooling mechanism includes a cooling tank for holding coolant, a pipe disposed on the cooling tank, a nozzle 13 disposed at one end of the pipe, a pump body connected in series on the pipe, and a switch button 7 electrically connected to the pump body for controlling the start and stop of the pump body.

[0029] When the moving part 3 moves to the processing position and the switch button 7 is pressed, the switch button 7 controls the pump to start. The pump delivers coolant from the cooling tank through pipes to the nozzle 13, which sprays the coolant onto the inner ring 18 of the bearing being processed, thus cooling it. When the moving part 3 leaves the processing position and the switch button 7 is released, the pump stops working, and the coolant delivery stops. This cooling mechanism has a simple structure, achieving coolant delivery and spraying through the pump and pipes. The linkage between the moving part 3 and the pump's start / stop control ensures effective cooling during processing while preventing coolant waste.

[0030] like Figure 2 and Figure 4 As shown, in some embodiments, the clamping unit includes a slot frame 14 fixedly mounted on the rotating shaft of the first motor 6, a bidirectional threaded rod 15 rotatably connected to the slot frame 14, and two clamping members 16 threadedly connected to the bidirectional threaded rod 15, with one end of the two clamping members 16 slidably connected in the slot frame 14.

[0031] When clamping the inner ring 18, the clamping member 16 passes through the inner ring 18. The double-threaded rod 15 can be rotated manually. Since the two clamping members 16 are threadedly connected to the double-threaded rod 15 and one end is slidably connected in the slot frame 14, the rotation of the double-threaded rod 15 will cause the two clamping members 16 to move towards the middle or sides along the slot frame 14, thereby achieving the clamping and releasing of bearing inner rings 18 of different diameters. The cooperative design of the double-threaded rod 15 and the clamping member 16 allows the clamping unit to adapt to bearing inner rings 18 of different specifications, exhibiting good versatility and flexibility.

[0032] In some embodiments, the clamping member 16 has an elastic pad at one end for clamping the inner ring 18. The elastic pad effectively prevents the inner ring 18 from sliding and loosening during clamping, ensuring clamping stability. Simultaneously, the elastic pad also acts as a buffer, reducing damage to the surface of the inner ring 18 by the clamping member 16 and improving product quality.

[0033] like Figure 5 As shown, in some embodiments, the bottom of the moving part 3 is provided with two sets of sliding grooves 17, which are respectively used to cooperate with the two sides of the track 2. This structural design ensures the smoothness and accuracy of the moving part 3 on the track 2, reduces vibration and errors during the movement process, and helps to improve the transfer and positioning accuracy of the transfer clamping mechanism for the bearing inner ring 18, thereby improving the machining accuracy of the entire device.

[0034] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0035] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
