Description

Technical Field

[0001] This utility model relates to the field of chuck technology, and in particular to a chuck structure that improves the efficiency of ultra-precision machining. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts and reduce the coefficient of friction during their movement. Oilstones are generally used on ultra-precision machines for grinding bearings.

[0003] After a period of use, the oilstone will wear down, the preload between the oilstone and the bearing will decrease, and the machining accuracy will be reduced. Therefore, it is necessary to compensate for the length of the oilstone. The existing chuck structure is not convenient for workers to control the compensation length. Workers need to make repeated adjustments, which takes a long time and reduces the machining efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a chuck structure that improves the efficiency of ultra-precision machining, and to solve the problem that existing chuck structures are inconvenient for operators to control the compensation length, require repeated adjustments, consume a lot of time, and reduce machining efficiency.

[0005] To achieve the above objectives, a chuck structure for improving ultra-precision machining efficiency is provided, comprising: a mounting base and a compensating rod, wherein a rotating ring is fixedly connected to the outside of the compensating rod, a rotating ring is rotatably connected to the side of the rotating ring, and a measuring scale is slidably connected inside the mounting base, wherein the end of the measuring scale away from the mounting base is in contact with the side of the rotating ring, which facilitates the operator in compensating for the length of the whetstone, facilitates the operator in controlling the compensation length, eliminates the need for repeated adjustments, and helps to improve work efficiency;

[0006] The upper surface of the mounting base is fitted with a cover plate, and two first screws are threaded inside the cover plate. One end of each of the two first screws is threaded inside the mounting base. The end of the measuring scale away from the mounting base is fixedly connected to a mounting plate. The mounting plate is threaded inside a second screw, and one end of the second screw is threaded inside a rotating ring. This facilitates the replacement of the measuring scale by the operator and increases the convenience of the device.

[0007] According to the aforementioned chuck structure for improving ultra-precision machining efficiency, the mounting base has mounting holes on its side, and the inner surface of the mounting holes is provided with internal threads to facilitate the fixing of the mounting base.

[0008] According to the aforementioned chuck structure for improving ultra-precision machining efficiency, two mounting cylinders are inserted inside the compensation rod, and a fixing bolt is threaded inside the compensation rod. One end of the fixing bolt is attached to the side of one of the mounting cylinders. The oil head can be easily pressed and fixed through the mounting cylinder and the fixing bolt.

[0009] According to the aforementioned chuck structure for improving ultra-precision machining efficiency, an oil head is inserted inside the compensation rod, and the oil head is located between two mounting cylinders, allowing for convenient grinding of the workpiece.

[0010] According to the aforementioned chuck structure for improving ultra-precision machining efficiency, the side surface of the rotating ring is provided with anti-slip texture to increase friction during rotation and prevent slippage.

[0011] According to the aforementioned chuck structure for improving ultra-precision machining efficiency, the longitudinal section of the rotating ring is annular, which facilitates the fitting of the rotating ring.

[0012] According to the aforementioned chuck structure for improving ultra-precision machining efficiency, a square disassembly groove is provided on the side of the fixing bolt to facilitate the worker's rotation of the fixing bolt.

[0013] According to the aforementioned chuck structure for improving ultra-precision machining efficiency, one end of the oil head extends to the outside of the mounting cylinder, facilitating contact with the workpiece surface to be ground.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. When it is necessary to rotate the compensating rod to compensate for the length of the asphalt stone, the compensating rod can be extended by rotating the rotating ring. The rotating ring can prevent the measuring ruler from rotating with the rotating ring. The measuring ruler makes it easy for the staff to know the compensation length and control the compensation length without repeated adjustments, which helps to improve work efficiency.

[0016] 2. When the surface of the measuring ruler is severely worn, the first screw can be removed to release the cover plate from limiting the measuring ruler. The second screw can be removed to easily release the limiting effect on the mounting plate and the measuring ruler, making it easier for staff to replace the measuring ruler and increasing the convenience of the device.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] Reference Figure 1-4 This utility model provides a chuck structure for improving ultra-precision machining efficiency, comprising: a mounting base 1 and a compensating rod 2. A rotating ring 3 is fixedly connected to the outside of the compensating rod 2. The rotating ring 3 is used to drive the compensating rod 2 to rotate. A rotating ring 10 is rotatably connected to the side of the rotating ring 3. The rotating ring 10 is used to prevent the measuring ruler 4 from rotating with the rotating ring 3. The measuring ruler 4 is slidably connected inside the mounting base 1 for the operator to control the compensation length. The end of the measuring ruler 4 away from the mounting base 1 is in contact with the side of the rotating ring 10.

[0027] The cover plate 5 is fitted onto the upper surface of the mounting base 1. The cover plate 5 is used to limit the measuring ruler 4. Two first screws 6 are threaded inside the cover plate 5. The first screws 6 are used to fix the cover plate 5. One end of each of the two first screws 6 is threaded inside the mounting base 1. The end of the measuring ruler 4 away from the mounting base 1 is fixedly connected to the mounting plate 13. The mounting plate 13 is threaded inside the second screw 14.

[0029] Two mounting cylinders 7 are inserted inside the compensating rod 2. A fixing bolt 9 is threaded inside the compensating rod 2. One end of the fixing bolt 9 is in contact with the side of one of the mounting cylinders 7. By pushing one of the mounting cylinders 7 through the fixing bolt 9, it cooperates with the other mounting cylinder 7 to clamp and fix the oil head 8.

[0030] The compensating rod 2 is internally connected to an oil head 8, which is located between two mounting cylinders 7 and is used for machining.

[0031] The rotating ring has anti-slip textures on its three sides to increase friction.
