Abstract
Description
Technical Field
[0001] This invention relates to the field of bearing processing technology, and in particular to a bearing turning processing equipment. Background Technology
[0002] Bearing turning refers to the machining of bearings using mechanical equipment such as lathes. Usually, tools such as cutting tools are used to turn the bearing multiple times to ensure that its size and shape meet the requirements.
[0003] However, during the turning process of bearings, it is necessary to maintain the stability of the bearing at all times to avoid affecting the machining quality due to vibration. Currently, the conventional method is to fix the bearings for machining using a three-jaw chuck. However, the contact points between the three fixed jaws of the three-jaw chuck and the bearing are relatively few. Especially when the bearing needs to be rotated for machining, the clamping effect of the three-jaw chuck on the bearing is not ideal. Moreover, since the thickness of the bearing is generally relatively thin, when the clamping force of the three-jaw chuck is too large, problems such as bearing deformation are also likely to occur. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bearing turning equipment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A bearing turning machine includes a worktable, a base for placing a bearing ring to be processed, a turntable distributed vertically opposite to the base, a turning tool on one side of the turntable, a pressing member laterally disposed on the base, a top column abutting the pressing member outwardly on the inner side of the base, an arc-shaped pressing rod opposite to the pressing member, and a pressing wheel rotatably disposed on the arc-shaped pressing rod and abutting the inner wall of the bearing ring.
[0007] Preferably, the base is provided with sliding rods that slide through the worktable at intervals, and the outer periphery of the sliding rods is fitted with springs that abut against the worktable and the base. The top column is fixed on the worktable, and the upper end of the top column is provided with an inclined abutment surface one. The sliding plate of the pressing member is provided with an abutment surface two that matches the abutment surface one.
[0008] Preferably, the base is provided with a sliding sleeve that corresponds to the pressing member, and the sliding plate is slidably disposed in the sliding sleeve.
[0009] Preferably, the base has a groove, in which a ball is disposed and a rotating plate abuts against the ball, and the bearing ring extends into the groove and abuts against the rotating plate.
[0010] Preferably, a stop plate is fixedly installed on the base, and the stop plate abuts against the upper end of the rotating plate.
[0011] Preferably, the turntable is rotatably mounted on a mounting plate, and a lifting rod for driving the turntable to move up and down is connected to the mounting plate. The turntable can rotate and press against the bearing ring.
[0012] Preferably, a motor is provided on the mounting plate, a wheel is mounted on the output shaft of the motor, and a transmission belt connects the wheel and the turntable.
[0013] The beneficial effects of this invention are:
[0014] 1. A circumferentially distributed pressing component is set on the base. The pressing component abuts against the inner wall of the bearing ring through the top column, and the bearing ring is fixed by multiple points of abutment roller. The bearing ring is pressed down from the top and bottom by the turntable and the base, thereby improving the stability of the bearing ring during rotary turning and ensuring the machining quality of the bearing ring.
[0015] 2. This invention uses an arc-shaped abutment rod in conjunction with a pressure roller to flexibly abut and fix the bearing ring at multiple points, thereby suppressing and absorbing the vibration generated during the turning process of the bearing ring and improving the turning quality of the bearing ring. Furthermore, by setting multiple points to fix the bearing ring, the clamping force on the bearing ring can be appropriately reduced to avoid deformation of the bearing ring and ensure the reliability of the bearing ring processing.

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0024] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.
[0025] like Figures 1-6 As shown, a bearing turning machine includes a worktable 1, on which a base 2 for placing a bearing ring 5 to be processed is provided, and a turntable 3 is distributed vertically opposite to the base 2. The base 2 has a groove 21, and the lower end of the bearing ring 5 is engaged in the groove 21. The turntable 3 can be lowered and displaced to abut against the upper end of the bearing ring 5 to abut and fix the upper and lower ends of the bearing ring 5.
[0026] A cutting tool 4 is provided on one side of the turntable 3. The cutting tool 4 can be moved closer to the bearing ring 5. The turntable 3 drives the bearing ring 5 to rotate so that the outer circumference of the bearing ring 5 can be machined by the cutting tool 4.
[0027] Specifically, the turntable 3 is rotatably mounted on the mounting plate 31, and the mounting plate 31 is connected to a lifting rod 34 that drives the turntable 3 to rise and fall synchronously, so that the turntable 3 can rotate and press against the bearing ring 5.
[0028] Furthermore, a motor 32 is provided on the mounting plate 31, and a wheel 33 is mounted on the output shaft of the motor 32. A transmission belt 331 is connected between the wheel 33 and the turntable 3, thereby driving the transmission belt 331 to rotate the turntable 3 through the motor 32.
[0029] Furthermore, the groove 21 is provided with a ball bearing 221 and a rotating plate 22 abutting against the ball bearing 221. The bearing ring 5 extends into the groove 21 and abuts against the rotating plate 22. A stop plate 222 is fixedly installed on the base 2. The stop plate 222 abuts against the upper end of the rotating plate 22. The stop plate 222 limits the rotation of the rotating plate 22. When the bearing ring 5 is rotated and machined, the rotating plate 22 can cooperate with the bearing ring 5 to perform a smoother rotational machining, which makes the machining of the bearing ring 5 more stable and reliable.
[0030] The base 2 is provided with sliding rods 12 that slide through the worktable 1 at intervals. The sliding rods 12 are circumferentially fixed to the lower end of the base 2. The outer periphery of the sliding rods 12 is fitted with springs 13 that abut against the worktable 1 and the base 2. The springs 13 buffer the downward displacement of the base 2.
[0031] A pressing member 24 is transversely disposed on the base 2. There are multiple pressing members 24 distributed circumferentially on the base 2. A top column 11 is provided on the inner side of the base 2 to abut against the pressing member 24. The top column 11 is fixed on the worktable 1. The sliding rod 12 is distributed on the outer periphery of the top column 11, and an abutment surface 111 is inclinedly disposed on the upper end of the top column 11.
[0032] Furthermore, the sliding plate 241 of the pressing member 24 is provided with a second pressing surface 242 that is adapted to the first pressing surface 111, and the base 2 is provided with a sliding sleeve 23 that corresponds to the pressing member 24. The sliding plate 241 is slidably disposed in the sliding sleeve 23. When the base 2 is pressed and displaced downward, the pressing member 24 abuts against the second pressing surface 242 through the first pressing surface 111 to drive the pressing member 24 to move outward laterally, and then the pressing member 24 abuts against the inner wall of the bearing ring 5 through the top column 11.
[0033] The pressing member 24 is provided with an arc-shaped pressing rod 243 and a pressing wheel 244 rotatably mounted on the arc-shaped pressing rod 243 and abutting against the inner wall of the bearing ring 5. The pressing wheel 244 is distributed on both sides of the sliding plate 241 so as to fix the bearing ring 5 by pressing against it at multiple points. The turning plate 3 cooperates with the base 2 to press the bearing ring 5 up and down, thereby improving the stability of the bearing ring 5 during rotary turning and ensuring the machining quality of the bearing ring 5.
[0034] Furthermore, in this embodiment, the arc-shaped abutment rod 243 cooperates with the pressure roller 244 to flexibly abut and fix the bearing ring 5 at multiple points, thereby suppressing and absorbing the vibration generated by the bearing ring 5 during turning and improving the turning quality of the bearing ring 5. In addition, by setting multiple points to fix the bearing ring 5, the clamping force on the bearing ring 5 can be appropriately reduced to avoid deformation of the bearing ring 5 and ensure the reliability of the bearing ring 5 processing.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
