Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of ultra-precision machine equipment, and in particular relates to an oilstone clamp for a wire drawing ultra-precision machine. Background Technology
[0002] Ultra-precision machining uses relatively low pressure to press an oilstone onto a rotating workpiece, creating a surface contact state, while the oilstone vibrates axially at a high frequency. Its main characteristics are: first, it can significantly improve surface roughness in a short time; second, because processing is done under low pressure, the surface structure of the workpiece does not undergo abnormal changes, and it can remove or largely remove the surface degradation layer generated during the grinding process; third, because the oilstone and workpiece are in surface contact and automatically conform to the shape, it can remove surface ripples that easily occur during grinding, thereby improving roundness.
[0003] In existing technologies, the ultra-precision machines used in bearing production have certain drawbacks in actual processing: since the whetstone is a key component to ensure the processing accuracy of the product, if the center position of the whetstone is unstable, it will affect the production quality; and most existing whetstone clamps hold the whetstone with two clamping plates and then lock it with screws. Although the above connection method can stably set up the whetstone, considering the high-frequency axial vibration of the whetstone, the stability of the screw setting will be affected, thus affecting the processing quality of the product. In addition, the existing conventional whetstone clamping fixtures are relatively inconvenient to clamp the workpiece, increasing the manual labor intensity and failing to meet the production needs. Utility Model Content

Detailed Implementation
[0012] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0013] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0014] Examples, such as Figures 1-6As shown, an oilstone clamp for a wire drawing ultra-precision machine includes an ultra-precision machine body. A workpiece clamping assembly 1 is provided on one side of the upper part of the ultra-precision machine body. The workpiece clamping assembly 1 is a device component used in the prior art for clamping workpieces to be processed. Its specific working principle and working method are conventional technical means in the prior art, and the specific usage will not be elaborated. Further, a circumferential limiting assembly 2 is provided on the outer side of the workpiece clamping assembly 1, which can limit the outer circumferential surface of the workpiece to ensure the stability of its central position. A transverse block 3 is provided on the outer side of the ultra-precision machine body. A vertical lifting adjustment assembly 4 is provided above the transverse block 3. An end face limiting assembly is provided at the output end of the vertical lifting adjustment assembly 4. 5. The aforementioned end-face limiting component 5 can be adjusted in position using the vertical lifting adjustment component 4, especially achieving synchronous adjustment. It cooperates with the upper and lower outer end faces of the workpiece, and together with the circumferential limiting component 2, limits the position of the workpiece, improving the stability of its position and preventing it from falling. Furthermore, a transverse frame 6 is provided on one side of the upper part of the ultra-precision machine body. An ultra-precision oscillation mechanism 7 is installed on the transverse frame 6, and an oilstone ultra-precision head 8 is installed on one side of the ultra-precision oscillation mechanism 7. For the above equipment setup, the ultra-precision oscillation mechanism 7 uses mechanical oscillation to drive the oilstone ultra-precision head 8 to reciprocate. The oilstone ultra-precision head 8 is located at the front end of the ultra-precision oscillation component. The ultra-precision head 8, placed on the ultra-precision oscillation component, includes an F-shaped mounting bracket 81. An ultra-precision drive cylinder 82 is located on one side of the mounting bracket 81. When compressed air is supplied to the ultra-precision drive cylinder 82 in the ultra-precision head 8, the piston rod of the ultra-precision pressure cylinder moves, causing the oilstone in the ultra-precision head 8 to press against the workpiece surface and maintain a certain pressure, thereby ensuring the smooth operation of the workpiece production process. The establishment of the above-mentioned components is based on existing mature technology and is readily known to those skilled in the art; further details are omitted. Additionally, a movable plate 83 is provided at the output end of the ultra-precision drive cylinder 82. One side is provided with an oilstone clamp body 9, and the mounting frame 81 is provided with a limit rod 42, which is symmetrically set about the output end of the ultra-precision drive cylinder 82 and limits the movement direction of the moving plate 83. The oilstone clamp body 9 can replace the existing bolt connection method to conveniently clamp the workpiece, reduce the operation difficulty in the connection and installation process, and improve the stability of the oilstone setting position to a certain extent, preventing it from falling and meeting the usage requirements. With the setting of the output end of the ultra-precision drive cylinder 82 and the limit rod 42, the smoothness of its output movement direction can be ensured, which greatly improves the stability of the equipment during movement, prevents it from jamming, and ensures the usage requirements. In the above process: the circumferential limiting component 2 and the end face limiting component 5, working together, can contact and abut against the outer circumferential surface and end face of the workpiece to be processed, and limit its position, ensuring the stability of the workpiece's position and ensuring the smooth progress of workpiece production and processing. The oilstone clamp body 9 can replace the existing bolt connection method to conveniently clamp the workpiece, reduce the operational difficulty in the connection and installation process, and also improve the stability of the oilstone's position to a certain extent, preventing it from falling off, thus meeting the usage requirements. This device is reasonably designed, simple in structure, easy to process, and can realize convenient installation of oilstone workpieces, improve their stability, reduce the possibility of workpiece loosening, ensure the molding quality of the product, reduce the intensity of manual labor, and fully meet the usage requirements.
[0015] To achieve circumferential positioning of the workpiece and ensure its stability, the circumferential positioning component 2 includes an L-shaped stabilizing frame 21. The end of the stabilizing frame 21 is provided with a longitudinally rotating longitudinal positioning bearing 22. Specifically, at least two sets of circumferential positioning components 2 are provided. One set of circumferential positioning components 2 is located below the workpiece, and the other set is located on one side of the workpiece. The cooperation between the two sets can limit the outer periphery of the workpiece and ensure the stability of its position. At the same time, it can cooperate with the end face positioning component 5 to limit the position of the workpiece and prevent it from shifting.
[0016] To achieve end-face positioning of the workpiece, especially adaptable to workpieces of different sizes, the vertical lifting adjustment assembly 4 includes a housing 41. A limiting slide rod 84 is installed inside the housing 41. A bidirectional lead screw 43 is installed on one side of the limiting slide rod 84. Vertically adjustable lifting plates 44 are installed on the upper and lower sides of the bidirectional lead screw 43. The end-face positioning assembly 5 includes a support plate 51 connected to the lifting plates 44. A transversely rotating limiting bearing 52 is installed at the end of the support plate 51. Specifically, threads are formed on both sides of the outer periphery of the bidirectional lead screw 43, and the threads on both sides are mirror-image about the geometric center of the bidirectional lead screw 43. That is, when the bidirectional lead screw 43 rotates, it can drive the two lifting plates 44 to move closer or further apart during operation. The movement and adjustment are carried out in a disengaging manner. The above-mentioned operating mode can adjust the position of the end face limiting component 5. In this way, the upper and lower end face limiting components 5 can be adjusted synchronously and act on the end face of the workpiece to limit its position. It should be further explained that the transverse block 3 can be moved and adjusted in the transverse direction to ensure that the end face limiting component 5 can approach the workpiece, thereby realizing convenient limiting of the workpiece, greatly improving the functionality of the device and meeting the usage requirements. Of course, after the transverse block 3 is moved to the appropriate position, it can be locked with bolts. As for the end face limiting component 5, the transverse limiting bearing 52 that rotates in the transverse direction can limit the outer end face of the workpiece and, together with the circumferential limiting component 2, realize the stability of the workpiece's position, improving the functionality of the device.
[0017] To facilitate the clamping of the oilstone and improve its stability, the oilstone clamp body 9 includes a concave-shaped cover 91. Arc-shaped extension plates 911 are provided at both lower ends of the cover 91. These extension plates 911 possess elasticity, meaning they can open relative to the cover 91 and use their elasticity to press the workpiece. The oilstone body 11 is housed inside the cover 91. A clamping plate 92 is located at the top inside the cover 91, and a locking screw 93 is located at the top of the cover 91. A connecting screw hole 912 is provided at the top inside the cover 91. Specifically, the extension plates... The extension plate 911 and the cover 91 are integrally formed. A protective pad is provided on the inner side of the extension plate 911 to prevent damage to the workpiece and ensure ease of use. In use, the oilstone to be clamped is taken and fed into the cover 91 from one side until the top of the oilstone is locked inside the cover 91, and the bottom of the oilstone is pressed against the extension plate 911 to ensure its stability. To further improve the stability of the oilstone, the locking screw 93 is rotated. This rotation acts on the pressing plate 92, causing the pressing plate 92 to press against the oilstone, thus completing the positioning of the oilstone. The positioning is designed to prevent displacement. Considering that the outer end face of the whetstone is in contact with the workpiece, the locking screw 93 can longitudinally limit and tighten the whetstone's position, thus ensuring its stability. A square hole 913 is provided inside the cover 91, and a clamping component 10 is installed within the square hole 913. The clamping component 10 includes a frame 101 designed in a U-shape, with an arc-shaped outer end face. One side of the frame 101 has an L-shaped locking block 102 that fits and engages with the square hole 913. Specifically, the arc-shaped frame 101... The workpiece can be inserted through the square hole 913 and engaged with the end face of the square hole 913 by the two side locking blocks 102 of the frame 101. This design not only allows the outer end face of the frame 101 to contact the workpiece, but also the arc-shaped end face of the frame 101 has a certain elasticity, which can be used to press it onto the workpiece. On the other hand, after the locking blocks 102 of the frame 101 are engaged with the square hole 913, it can ensure that the clamping component 10 presses the oilstone and cooperates with the cover 91, which greatly improves the stability of the oilstone workpiece placement. Compared with the oilstone installation process in the prior art, this installation method is simple and convenient to operate and has strong practicality.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
