Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and specifically discloses a bearing processing device with controllable precision. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. According to the different frictional properties of the moving elements, bearings can be divided into two main categories: rolling bearings and sliding bearings. Rolling bearings have been standardized and serialized, but compared with sliding bearings, they have larger radial dimensions, vibration and noise, and are also more expensive. Rolling bearings generally consist of four parts: outer ring, inner ring, rolling elements and cage. The outer diameter of the ring often needs to be machined to ensure its accuracy.

[0003] Chinese patent CN210548537U discloses a bearing processing device with controllable precision. In use, the bearing is placed on the mounting base, and the stepper motor is activated by an external controller. The output shaft of the stepper motor drives the active bevel gear to rotate, and the active bevel gear drives the threaded rod to rotate through the driven bevel gear. The threaded rod drives the cutting motor to move through the threaded sleeve, thereby adjusting the processing precision. The cutting motor is activated by the external controller, and the output shaft of the cutting motor drives the tool to rotate, thus achieving the effect of controllable precision.

[0004] 1. In actual machining, bearings (especially when machining the outer diameter of the outer ring) require a stable clamping force to clamp and fix the outer ring of the bearing in order to avoid displacement or vibration caused by cutting force. The aforementioned document discloses a precision controllable bearing machining device, which mentions "placing the bearing on the mounting seat", but does not explain how to clamp the bearing. There is no active clamping mechanism, which cannot guarantee that the bearing is subjected to a suitable clamping force, which may cause the bearing to shift or rotate due to cutting force.

[0005] 2. Furthermore, the meshing of the driving and driven bevel gears in the transmission device can lead to wear and tear over time, creating gaps. This prevents the stepper motor's rotational motion from being precisely transmitted to the threaded rod, ultimately causing errors in the horizontal displacement of the cutting device. This makes it difficult to achieve micron-level precision control. If the threaded rod uses a standard precision design, its pitch error will accumulate and be transmitted to the displacement of the threaded sleeve. For example, when machining high-precision bearings, even a small pitch deviation in the threaded rod can directly exceed the upper limit of precision control. Therefore, a precision-controllable bearing machining device is needed to solve this problem. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Please see Figure 1-4 A precision controllable bearing processing device includes a plate 1 and a turning tool 24. The upper end of the plate 1 is rotatably connected to a horizontal plate 4 via a turntable 2, and a clamping mechanism is provided on the upper side of the horizontal plate 4.

[0029] The clamping mechanism includes a fixed clamping plate 5 fixedly connected to the upper end of the horizontal plate 4. A pressure plate 6 and a movable clamping plate 7 are provided on the right side of the fixed clamping plate 5. A pressure sensor 8 is installed on the right end of the pressure plate 6, which abuts against the left end of the movable clamping plate 7. An alarm 11 is installed on the outer wall of the pressure plate 6.

[0030] A drive mechanism is provided on the right side of the fixed clamping plate 5;

[0031] A translation plate 18 is provided on the upper side of the plate 1. A first ball screw nut 19 is fixedly connected through the outer wall of the translation plate 18. Two first connecting plates 20 are fixedly connected to the upper end of the plate 1. A first ball screw 21 that is threadedly connected to the first ball screw nut 19 is rotatably connected between the two first connecting plates 20. The first ball screw 21 is driven by a first servo motor 22 installed on the outer wall of one of the first connecting plates 20.

[0032] A lifting plate 23 is provided at the right end of the translation plate 18. A second ball screw nut 25 is fixedly connected through the outer wall of the lifting plate 23. Two second connecting plates 26 are fixedly connected to the right end of the translation plate 18. A second ball screw 27, which is threadedly connected to the second ball screw nut 25, is rotatably connected between the two second connecting plates 26. The second ball screw 27 is driven by a second servo motor 28 installed on the outer wall of one of the second connecting plates 26.

[0033] In this embodiment: the bearing outer ring to be processed is placed between the fixed clamping plate 5 and the movable clamping plate 7. Then, the pressure plate 6 is driven to move to the right by the drive mechanism. The movable clamping plate 7 is pushed to the right by the pressure sensor 8 to apply clamping force to the bearing outer ring. During the clamping process, the pressure sensor 8 monitors the pressure applied to the movable clamping plate 7 in real time and transmits the pressure signal to the alarm 11. When the pressure reaches a preset appropriate value, the alarm 11 can issue a prompt to inform the operator to stop the operation, so as to ensure that the bearing outer ring is subjected to a stable and appropriate clamping force, thereby improving the reliability of clamping the bearing outer ring, so as to ensure that it is subjected to a stable clamping force and preventing the bearing outer ring from moving and rotating due to cutting force.

[0034] The turntable 2 then drives the horizontal plate 4 to rotate, thereby causing the outer ring of the clamped bearing to rotate, in preparation for turning.

[0035] During turning, the first servo motor 22 is started, driving the first ball screw 21 to rotate. The first ball screw 21 is threadedly connected to the first ball screw nut 19 on the outer wall of the translation plate 18. Since the translation plate 18 is slidably connected to the upper end of the plate 1 via a slide rail, the rotation of the first ball screw 21 causes the translation plate 18 to make horizontal linear motion on the plate 1, thereby adjusting the horizontal position of the turning tool 24. Then, the second servo motor 28 is started, driving the second ball screw 27 to rotate. The second ball screw 27 is threadedly connected to the second ball screw nut 25 on the outer wall of the lifting plate 23. Since the lifting plate 23 is slidably connected to the right end of the translation plate 18 via a slide rail, the second ball screw 27... Rotation causes the lifting plate 23 to move vertically on the translation plate 18, thereby adjusting the vertical position of the turning tool 24. Since the turning tool 24 can move in the horizontal and vertical directions according to a preset path, it can accurately turn the outer ring of the bearing. By using the first ball screw 21 with the first ball screw nut 19 and the second ball screw 27 with the second ball screw nut 25 to control the horizontal and vertical position of the turning tool 24, the transmission mechanism has the advantages of high precision, high efficiency, and low friction. It can effectively avoid the problem of pitch error accumulation in traditional threaded rod transmission, achieve micron-level precision control, and thus improve the machining accuracy of the outer ring of the bearing.

[0036] As a technical optimization of this utility model, the driving mechanism includes a vertical plate 12 fixedly connected to the right end of the horizontal plate 4, a screw 13 rotatably connected between the fixed clamping plate 5 and the vertical plate 12, the screw 13 passing through the pressure plate 6 and threadedly connected to the pressure plate 6, a driving frame 14 fixedly connected to the right end of the vertical plate 12, a worm gear 15 rotatably connected inside the driving frame 14, a worm wheel 16 meshing with the outer wall of the worm gear 15, a transmission shaft passing through the vertical plate 12 fixedly connected between the worm wheel 16 and the screw 13, a handwheel extending to the outside of the driving frame 14 fixedly connected to one end of the worm gear 15, a sliding groove opened at the upper end of the horizontal plate 4, and a slider fixedly connected to the pressure plate 6 slidably connected inside the sliding groove.

[0037] In this embodiment: rotating the handwheel drives the worm gear 15 inside the drive frame 14 to rotate. The worm gear 15 meshes with the worm wheel 16, driving the worm wheel 16 to rotate. The worm wheel 16 drives the screw 13 to rotate through the transmission shaft. The screw 13 is threadedly connected to the pressure plate 6, and the pressure plate 6 slides in the groove of the horizontal plate 4 through the slider. The rotation of the screw 13 causes the pressure plate 6 to move linearly. In addition, the worm gear 15 and worm wheel 16 mechanism has self-locking properties, which can ensure that the position of the pressure plate 6 is stable after the clamping force is applied, preventing loosening and ensuring reliable clamping of the outer ring of the bearing.

[0038] As a technical optimization of this utility model, the left end of the movable clamping plate 7 is fixedly connected to two limiting rods 9 that penetrate the pressure plate 6 and are slidably connected to the pressure plate 6, and the left ends of the two limiting rods 9 are fixedly connected to baffles 10.

[0039] In this embodiment: when the movable clamping plate 7 moves under the push of the pressure plate 6, the limiting rod 9 passes through the pressure plate 6 and is slidably connected to it, restricting the moving direction of the movable clamping plate 7 and preventing it from deviating. The baffle 10 can prevent the limiting rod 9 from coming out of the pressure plate 6.

[0040] As a technical optimization of this utility model, a drive motor 3 with its output end fixedly connected to the turntable 2 is installed at the lower end of the flat plate 1.

[0041] In this embodiment: the drive motor 3 at the lower end of the flat plate 1 is started, and its output end drives the turntable 2 to rotate, and the turntable 2 drives the horizontal plate 4 to rotate.

[0042] As a technical optimization of this utility model, the translation plate 18 is slidably connected to the upper end of the plate 1 via a slide rail, and the lifting plate 23 is slidably connected to the right end of the translation plate 18 via a slide rail.

[0043] In this embodiment: the translation plate 18 slides on the upper end of the plate 1 via the slide rail. When the first ball screw 21 rotates, it makes the translation plate 18 move horizontally on the slide rail through the cooperation with the first ball screw nut 19. The lifting plate 23 slides on the right end of the translation plate 18 via the slide rail. When the second ball screw 27 rotates, it makes the lifting plate 23 move vertically on the slide rail through the cooperation with the second ball screw nut 25.

[0044] As a technical optimization of this utility model, the opposite sides of the fixed clamping plate 5 and the movable clamping plate 7 are both arc-shaped structures and are provided with anti-slip layers. The opposite sides of the fixed clamping plate 5 and the movable clamping plate 7 are both fixedly connected with arc-shaped positioning plates 17.

[0045] In this embodiment: by setting two arc-shaped positioning plates 17, the clamping position of the bearing outer ring is positioned. The opposite sides of the fixed clamping plate 5 and the movable clamping plate 7 are arc-shaped, which can better fit the shape of the bearing outer ring. The anti-slip layer increases the friction between the bearing outer ring and the anti-slip layer.

[0046] As a technical optimization of this utility model, the turning tool 24 is installed on the right end of the lifting plate 23.

[0047] In this embodiment: the turning tool 24 is installed at the right end of the lifting plate 23. Through the horizontal movement of the translation plate 18 and the vertical movement of the lifting plate 23, the turning tool 24 can reach the appropriate machining position to perform turning machining on the rotating bearing.

[0048] The working principle and usage process of this utility model are as follows: The outer ring of the bearing to be processed is placed between the fixed clamping plate 5 and the movable clamping plate 7. The outer ring of the bearing is positioned by two arc-shaped positioning plates 17. Then, the handwheel is rotated, which drives the worm gear 15 to rotate within the drive frame 14. Since the worm gear 15 meshes with the worm wheel 16, the rotation of the worm gear 15 will drive the worm wheel 16 to rotate. The worm wheel 16 drives the screw 13 to rotate through the transmission shaft. The screw 13 is threadedly connected to the pressure plate 6, and the pressure plate 6 slides to the right in the groove at the upper end of the horizontal plate 4 through the slider. Therefore, when the screw 13 rotates, the pressure plate 6 will move to the right along the screw 13. When the pressure plate 6 moves to the right, it will... Pressure sensor 8 pushes the movable clamping plate 7 to move to the right, applying clamping force to the outer ring of the bearing. During the clamping process, pressure sensor 8 monitors the pressure applied to the movable clamping plate 7 in real time and transmits the pressure signal to alarm 11. When the pressure reaches a preset appropriate value, alarm 11 can issue a prompt to inform the operator to stop turning the handwheel, ensuring that the outer ring of the bearing is subjected to a stable and appropriate clamping force. The setting of limit rod 9 and baffle 10 prevents the movable clamping plate 7 from moving in the front-back, back-up and down directions, thereby improving the reliability of clamping the outer ring of the bearing, ensuring that it is subjected to a stable clamping force, and preventing the outer ring of the bearing from moving and rotating due to cutting force.

[0049] Then the drive motor 3 is started, and its output end drives the turntable 2 to rotate. The turntable 2 drives the horizontal plate 4 to rotate, which in turn causes the outer ring of the clamped bearing to rotate, preparing for turning.

[0050] During turning, the first servo motor 22 is started, driving the first ball screw 21 to rotate. The first ball screw 21 is threadedly connected to the first ball screw nut 19 on the outer wall of the translation plate 18. Since the translation plate 18 is slidably connected to the upper end of the plate 1 via a slide rail, the rotation of the first ball screw 21 causes the translation plate 18 to make horizontal linear motion on the plate 1, thereby adjusting the horizontal position of the turning tool 24. Then, the second servo motor 28 is started, driving the second ball screw 27 to rotate. The second ball screw 27 is threadedly connected to the second ball screw nut 25 on the outer wall of the lifting plate 23. Since the lifting plate 23 is slidably connected to the right end of the translation plate 18 via a slide rail, the second ball screw 27... Rotation causes the lifting plate 23 to move vertically on the translation plate 18, thereby adjusting the vertical position of the turning tool 24. Since the turning tool 24 can move in the horizontal and vertical directions according to a preset path, it can accurately turn the outer ring of the bearing. By using the first ball screw 21 with the first ball screw nut 19 and the second ball screw 27 with the second ball screw nut 25 to control the horizontal and vertical position of the turning tool 24, the transmission mechanism has the advantages of high precision, high efficiency, and low friction. It can effectively avoid the problem of pitch error accumulation in traditional threaded rod transmission, achieve micron-level precision control, and thus improve the machining accuracy of the outer ring of the bearing.
