Description

Technical Field

[0001] This utility model relates to the field of ultra-precision machine technology, and in particular to an oilstone ultra-precision machine with anti-slip function. Background Technology

[0002] Ultraprecision machining uses relatively low pressure to press an oilstone onto a rotating workpiece, creating surface contact. Simultaneously, the oilstone vibrates at a high frequency axially to perform ultraprecision machining. The oilstone mounted on the ultraprecision machine requires a swing mechanism to control its back-and-forth movement. Because this mechanism experiences significant vibrations during operation, the oilstone is prone to slippage during the swinging motion, which affects the machining quality of the bearing rings. Therefore, an oilstone ultraprecision machine with anti-slip functionality is proposed. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an oilstone superprecision machine with anti-slip function.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An oilstone superfinishing machine with anti-slip function includes a machine body and a shell of the machine body. An operating table is provided on the machine body, and an oilstone adjusting box is provided at the front end of the machine body. An mounting plate is connected to the side of the oilstone adjusting box through a connecting seat. The mounting plate is suspended above the operating table of the machine body. A guide plate is provided at the bottom of the mounting plate. A clamping plate is slidably connected to the inside of the guide plate along the horizontal direction. The clamping plate is used to hold oilstone blocks. A swing arm and a disc are rotatably connected to the surface of the mounting plate. A rotary block is rotatably connected to the disc at an eccentric position on its circular surface. A sliding arm is slidably connected to the outside of the rotary block. The upper end of the sliding arm is rotatably connected to the movable end of the swing arm, and the lower end of the sliding arm is rotatably connected to the clamping plate below. The swing arm drives the sliding arm to slide along the rotary block through its circumferential rotation, and drives the lower end of the sliding arm to slide back and forth horizontally along the guide plate.

[0006] In a preferred embodiment, a rotating shaft is provided on the mounting plate, and the swing arm is rotatably connected to the mounting plate via the rotating shaft. A motor is provided inside the oilstone regulating box, and the rotating shaft is driven to rotate circumferentially by the motor.

[0007] In a preferred embodiment, the center of the rotary block is rotatably connected to the disk via a fixed shaft.

[0008] In a preferred embodiment, a slot is formed on the arm of the sliding arm, and the rotary block is embedded in the slot and slides along it.

[0009] In a preferred embodiment, the lower end of the sliding arm is rotatably connected to the top of the clamp via a connecting shaft.

[0010] In a preferred embodiment, the bottom surface of the clamping disc has a receiving cavity for placing the oilstone block, and the side wall of the clamping disc is threaded with a bolt. The front end of the bolt is provided with a clamping plate, which clamps the oilstone block.

[0011] The beneficial effects of this utility model are:

[0012] The ultra-precision machine structure proposed in this solution solves the problem of oilstones easily loosening and slipping during grinding, which affects the quality of bearing processing. By using the circumferential rotation of the swing arm to achieve the sliding of the oilstone block, the amplitude of the swing and vibration of the oilstone block can be effectively reduced. At the same time, by using bolts to lock the oilstone block, it can be ensured that the oilstone block is in a stable clamping state and will not loosen or slip, which helps to improve the processing quality of bearing workpieces.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In this embodiment, refer to Figure 1-4An oilstone superfinishing machine with anti-slip function includes a machine body 1 and a shell 2 of the machine body 1. An operating table 4 is provided on the machine body 1. An oilstone adjustment box 3 is provided at the front end of the machine body 1. An mounting plate 6 is connected to the side of the oilstone adjustment box 3 through a connecting seat 5. The mounting plate 6 is suspended above the operating table 4 of the machine body 1.

[0020] The bottom of the mounting plate 6 is provided with a guide plate 13, and a clamping plate 14 is slidably connected to the guide plate 13 along the transverse direction. The clamping plate 14 is used to hold the oilstone block 18. In order to ensure that the clamping plate 14 can slide along the length direction of the guide plate 13, a long straight groove is opened in the guide plate 13. The groove can be designed as a dovetail groove or a channel of other shapes, and the clamping plate 14 is designed with a contour that matches the shape of the groove.

[0021] As attached Figure 4 As shown, the bottom surface of the chuck 14 has a cavity for holding the oilstone 18. Bolts 16 are threaded onto the side wall of the chuck 14, and a clamping plate 17 is provided at the front end of the bolts 16. The clamping plate 17 clamps the oilstone 18. The bolts 16 can push the clamping plate 17 forward, clamping the oilstone 18, thus achieving the purpose of clamping. The oilstone 18 is fixed by the bolts 16, which also facilitates the installation, removal, and replacement of new oilstones 18 by the workers. Locking the oilstone 18 ensures that its position does not shift, effectively preventing slippage and ensuring the smooth ultra-precision machining of the bearing ring.

[0022] A swing arm 8 and a disc 9 are rotatably connected to the surface of the mounting plate 6.

[0023] The mounting plate 6 is equipped with a rotating shaft 7, and the swing arm 8 is rotatably connected to the mounting plate 6 through the rotating shaft 7. The oilstone regulating box 3 is equipped with a motor, which drives the rotating shaft 7 to rotate circumferentially.

[0024] A rotating block 11 is rotatably connected to the disc 9 at an eccentric position on its circular surface. The center of the rotating block 11 is rotatably connected to the disc 9 via a fixed shaft 10. A sliding arm 12 is slidably connected to the outside of the rotating block 11. A strip groove is opened on the arm of the sliding arm 12, and the rotating block 11 is built into the strip groove and slides along it.

[0025] The upper end of the sliding arm 12 is rotatably connected to the movable end of the swing arm 8, and the lower end of the sliding arm 12 is rotatably connected to the top of the clamp 14 through the connecting shaft 15.

[0026] In order to ensure that the clamping plate 14 can slide naturally along a straight line by the drive of the sliding arm 12, a through slot is opened on the guide plate 13, and the lower end of the sliding arm 12 passes through the slot and is connected to the top of the clamping plate 14.

[0027] During its circumferential rotation, the swing arm 8 drives the sliding arm 12 to slide along the rotating block 11. The rotating block 11 is mounted on the eccentric surface of the disk 9. Therefore, when the swing arm 8 rotates, the sliding arm 12 drives the disk 9 to rotate, which in turn drives the clamping plate 14 connected to the lower end of the sliding arm 12 to slide back and forth laterally along the guide plate 13. The drive of the swing arm 8 ultimately achieves smooth back-and-forth sliding of the clamping plate 14. The oscillation of the clamping plate 14 during the back-and-forth sliding is relatively small, thus ensuring reliable clamping of the oilstone block 18.

[0028] The chuck 14 and the oilstone 18 at its bottom can slide back and forth in a straight line. When the bearing to be finely ground is placed on the operating table 4, the oilstone 18 is used to adhere to the surface of the bearing. Then, the oilstone 18 slides back and forth to perform ultra-fine grinding on the bearing ring.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
