Description

Technical Field

[0001] The present application relates to the field of machining, and in particular to a lathe tooling for a shock-resistant pressure gauge case joint. Background Art

[0002] In the field of machining technology, especially for the manufacture of precision instrument accessories such as anti-seismic pressure gauge case joints, traditional production processes face challenges in efficiency and flexibility. As one of the core components of the pressure gauge, the production process of anti-seismic pressure gauge case joints usually includes multiple fine processing steps, from the initial blank cutting to the final finishing, and each step requires high precision to ensure the reliable performance of the instrument. However, the key link - the processing of arc surfaces, has traditionally relied on machining centers, which is not only time-consuming, but also prone to extended processing cycles and tight equipment use when facing large-scale production needs.

[0003] Specifically, there are two major limitations in the arc surface milling of machining centers: first, the machining efficiency is relatively low, especially when processing complex curved surfaces. Compared with the continuous rotation cutting efficiency of lathes, its step-by-step milling method cannot fully utilize the equipment capacity; second, the clamping is complicated, and each clamping requires precise alignment, which increases the preparation time and reduces the production cycle. When the production plan is tight, especially when other equipment such as milling machines, slotting machines, and planing machines are also facing high-intensity operations, this bottleneck of the machining center will be more prominent, which may lead to difficulties in production scheduling and affect overall output.

[0004] In view of the above background, the machining industry urgently needs an innovative solution to break through the limitations of the current processing mode, especially to effectively utilize the high-efficiency rotation processing capabilities of the lathe to make up for the shortcomings of the machining center in processing specific geometric shapes. Therefore, the development of a lathe tooling specifically for anti-seismic pressure gauge case joints can not only improve the lathe's processing capabilities for non-rotating arc surfaces, but also simplify the clamping process and improve processing efficiency, becoming the key to solving the pain points of this industry. This provides a clear demand orientation and technical background for the research and development of a lathe tooling for anti-seismic pressure gauge case joints. Utility Model Content

[0026] The following is combined with Figure 1-9 This application is described in further detail.

[0027] The present application discloses a seismic pressure gauge case joint lathe tooling, comprising an intermediate turntable 1, a bottom turntable 2, and a pressure block 5. The intermediate turntable 1 is provided with an annular wall body, and a plurality of inwardly protruding steps 8 are provided on the inner side of the annular wall body, and the annular wall body and the steps 8 are surrounded to form a clamping groove 7; during processing, a seismic pressure gauge case joint workpiece 6 can be placed in the clamping groove 7; a plurality of pressure blocks 5 can be connected to one side of the step 8 of the intermediate turntable 1; the bottom turntable 2 is fixedly connected to the side of the step 8 away from the pressure block 5, and the side wall of the clamping groove 7, the pressure block 5, and the bottom turntable 2 jointly constrain the workpiece 6.

[0028] This embodiment provides a specific implementation of a seismic pressure gauge case joint lathe tooling. As shown in the figure, the tooling comprises an intermediate turntable 1, which is designed as an annular wall body, and several inward steps 8 are evenly distributed on the inner edge of the annular wall body. These steps and the annular wall body together form a slot 7, which is specifically used to fix the seismic pressure gauge case joint workpiece 6. The workpiece 6 is placed in the slot 7 to ensure stable positioning during processing.

[0029] The pressing block 5 is designed as a V-shaped structure 9, and the two ends are precisely matched with the cylindrical arc surface 10 of the workpiece 6, which improves the fit and stability of the processing. The pressing block 5 is connected to the fixing hole 13 on the step 8 of the intermediate turntable 1 through the connecting rod 14. The connecting rod 14 passes through the middle through hole 11 of the pressing block 5 and the fixing hole 13 on the step, ensuring the firm installation and adjustability of the pressing block 5. The V-shaped structure and arc surface design of the pressing block, as well as the tightening through the screw, jointly apply uniform pressure to the workpiece, ensuring the stability and precision during processing.

[0030] The bottom turntable 2 is in the shape of a disk, and an opening 12 is reserved in the center, so that the lathe chuck can directly clamp the outer contour of the middle turntable 1, thereby enhancing the stability of the entire system. The bottom turntable 2 is fixed to the side of the step 8 away from the pressure block 5, and together with the side wall of the slot 7 and the pressure block 5, it restrains and supports the workpiece 6 to prevent movement during processing. The opening 12 can facilitate the feeding of the tool.

[0031] A nut 3 is installed on the upper edge of the annular wall. The screw 4 is inserted into the nut 3 and adjusted to further constrain the pressing block 5, control the radial position of the pressing block, and ensure dynamic balance during processing. In addition, the middle turntable 1 and the bottom turntable 2 are made of high-strength, wear-resistant and tough alloy steel materials, which improves the overall durability and impact resistance of the tooling.

[0032] In the actual processing operation, the anti-seismic pressure gauge case joint workpiece 6 is first accurately placed in the slot 7 of the middle turntable 1, ensuring that it is in full contact with the bottom turntable 2 at the bottom of the slot to form a stable support base. Then, according to the size and shape of the workpiece, a suitable pressing block 5 is selected, and the arc surfaces 10 at both ends of its V-shaped structure 9 are tightly fitted with the workpiece surface to ensure accurate positioning during processing.

[0033] Subsequently, by adjusting the tightness of the connecting rod 14, the pressing block 5 is initially fixed at a predetermined position to ensure uniform contact between the pressing block and the workpiece. The operator can rotate the connecting rod 14 with the help of a torque wrench or an electric tool to accurately adjust the length of the connecting rod 14 until the pressing block 5 applies a suitable clamping force to the workpiece 6, which neither causes deformation of the workpiece nor ensures stability during processing. During this period, the radial position of the pressing block can be adjusted by adjusting the screw 4 inserted in the nut 3 to further constrain the pressing block 5.

[0034] After ensuring that all assembly steps are completed, the tooling is installed on the lathe chuck as a whole, and the rotary power of the lathe is used to feed the anti-vibration pressure gauge case joint with the turning tool for precision machining of the arc surface. During the machining process, the superiority of the tooling design is reflected: the stability of the annular wall, the precise positioning of the step 8 and the slot 7, the adjustment and clamping mechanism of the pressure block 5, and the open 12 design of the bottom turntable 2, together ensure the high efficiency, accuracy and continuity of the machining, while reducing the clamping time of the workpiece and improving the overall production efficiency.

[0035] Once the processing is completed, the pressing block 5 can be easily removed by loosening the connecting rod 14 in reverse operation, and the workpiece 6 can be taken out of the slot 7, completing a processing cycle. The high flexibility and convenience of this tooling design makes it simple and quick to replace the workpieces of different specifications of anti-seismic pressure gauge case joints, greatly improving the adaptability and flexibility of the machining production line.

[0036] The seismic-resistant pressure gauge case joint lathe tooling of this embodiment, through a carefully designed structural layout, not only simplifies the clamping process, but also greatly improves the efficiency of machining seismic-resistant pressure gauge case joints, meets the needs of mass production, and at the same time ensures the machining accuracy and the integrity of the workpiece, which is an important innovation in the field of machining.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
