Description

Technical Field

[0001] This utility model relates to the field of gasket technology, and in particular to a fixture tooling adapted to the production of thin gaskets of multiple diameters. Background Technology

[0002] In modern industrial production, thin gaskets are widely used in many fields such as machinery, electronics, and automobiles as important sealing and shock-absorbing components. With the diversification and refinement of industrial products, the market demand for thin gaskets of different diameters and specifications is increasing, which puts forward higher requirements for the production and processing of thin gaskets. Currently, in the production of thin gaskets, the commonly used fixtures are mostly special fixtures designed for specific specifications. Although these fixtures can ensure a certain level of accuracy and stability when processing thin gaskets of a single specification, when it is necessary to produce thin gaskets of different diameters, it is often necessary to change the entire set of fixtures. This not only makes the operation cumbersome and consumes a lot of mold change time, but also increases the cost for companies to purchase multiple sets of special fixtures. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the structure of traditional clamps is relatively fixed, making it difficult to adapt to plates with different shapes and surface characteristics. During the clamping process, problems such as plate offset and inaccurate positioning are prone to occur, resulting in a decrease in the processing accuracy of thin gaskets, an increase in the defect rate, and a decrease in production efficiency and product quality.

[0004] This utility model achieves the above objectives through the following technical solutions: A fixture adapted for the production of multi-diameter thin gaskets includes a fixed base plate. A sheet metal pressing mechanism is provided on one upper side of the fixed base plate. A telescopic adjustment guide plate is provided at the center of the fixed base plate. A plurality of limiting bolts are evenly and equidistantly arranged on the telescopic adjustment guide plate. Fixed posts are provided at each of the four bottom corners of the fixed base plate. The sheet metal pressing mechanism includes a pressing mechanism. First guide posts are provided on both sides of the pressing mechanism. Locking handles are provided below the first guide posts at the bottom of the pressing mechanism. A sheet metal is placed below the pressing mechanism. The first guide posts are fixed to the fixed base plate for use in pressing... The described pressing mechanism guides the workpiece and uses the locking handle for locking and limiting, adjusting the pressing position. By incorporating a sheet metal pressing mechanism, a telescopic adjustable guide plate, limit bolts, and fixing columns, a basic fixture frame suitable for producing thin gaskets of various diameters is constructed. The sheet metal pressing mechanism can stably press and fix the sheet metal, the telescopic adjustable guide plate, in conjunction with the limit bolts, can be flexibly adjusted according to the diameter of the thin gasket, and the fixing columns ensure the overall fixture is placed stably. This structural design allows the fixture to be compatible with sheet metal for producing thin gaskets of various diameters, improving versatility and production efficiency, and reducing the cost and time loss caused by changing fixtures of different specifications.

[0005] Furthermore, the pressing mechanism includes a fixed plate, with guide blocks on both sides of the upper end of the fixed plate, which are assembled and connected to the first guide post for vertical movement. Two fixed connecting posts are located at the center of the fixed plate, and each fixed connecting post has a movable bearing at its lower end. A guide wheel is positioned between the movable bearings. The combined design of the fixed plate, guide blocks, fixed connecting posts, movable bearings, and guide wheel in the pressing mechanism provides precise guidance and stable support for the pressing operation. The assembly and connection of the guide blocks and guide posts ensures the accuracy of the vertical movement of the pressing mechanism and prevents deviation. The fixed connecting posts, in conjunction with the movable bearings and guide wheel, reduce frictional resistance when applying pressure to the sheet metal, making the pressing process smoother. Simultaneously, the guide wheel can adaptively adjust its angle according to the surface condition of the sheet metal, enhancing adaptability to sheets of different shapes and improving the reliability and stability of the clamping.

[0006] Furthermore, the telescopic adjustment guide plate includes a first splicing plate, on one side of which a second splicing plate is provided. A plurality of guide holes are equidistantly arranged on the side wall of the first splicing plate near the second splicing plate. A plurality of second guide posts are arranged at corresponding positions on the opposite ends of the guide holes on the second splicing plate. The second guide posts are assembled and connected with the guide holes. Both the first and second splicing plates are provided with grooves for receiving plates of different sizes. The telescopic adjustment guide plate, using the first and second splicing plates, and through the assembly of guide holes and guide posts and the groove design, effectively receives and quickly adjusts plates of different sizes. This modular splicing structure allows operators to easily adjust the spacing of the guide plates according to the actual size of the thin gaskets without a complex disassembly and assembly process, greatly improving the flexibility and ease of use of the fixture and tooling, and enabling rapid adaptation to the production tasks of thin gaskets of different specifications.

[0007] Furthermore, the first and second splicing plates can be pulled together by the cooperation of the guide holes and the second guide post, and can be fixed by the limiting bolts.

[0008] Furthermore, the guide wheel surface is covered with a rubber anti-slip layer. When the sheet is placed under the pressing mechanism, the guide wheel contacts the sheet surface, increasing friction during pressure application and preventing the sheet from shifting. The rubber anti-slip layer on the guide wheel surface significantly increases the friction between it and the sheet, effectively preventing the sheet from shifting during the production of thin gaskets under pressure, thus ensuring the accuracy of the sheet's position during processing.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the modular splicing structure of the telescopic adjustable guide plate, operators can quickly adjust the fixture size according to the diameter of the thin gasket without replacing the entire set of fixtures, greatly shortening the mold change time; the sheet pressing mechanism, together with the locking handle, can quickly press down and fix, and the guide wheel can adaptively adjust when in contact with the sheet, making the clamping process efficient and smooth, significantly improving the production efficiency of thin gaskets of various specifications, and meeting diverse production needs.

[0010] 2. The precise fit between the guide block and the guide column in the pressing mechanism ensures that the pressing operation is vertical and without deviation; the rubber anti-slip layer on the surface of the guide wheel increases friction and prevents the sheet metal from shifting during processing; at the same time, the telescopic adjustment guide plate is fixed by the limit bolts to ensure the stability of the tooling structure during processing, comprehensively guaranteeing the processing accuracy of the thin gasket, reducing the defect rate, and improving product quality.

[0011] 3. This fixture is compatible with thin gaskets of various diameters through its structural design, reducing the cost for companies to purchase multiple sets of special fixtures; at the same time, its modular design facilitates maintenance and replacement of vulnerable parts, extending the service life of the fixture; in addition, its efficient and stable processing performance reduces material waste and rework costs caused by fixture problems, thus comprehensively reducing the company's production and operating costs.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Combination Figure 1-4 As shown, a fixture adapted for the production of multi-diameter thin gaskets includes a fixed base plate 1, a sheet metal pressing mechanism 2 disposed on one side of the upper end of the fixed base plate 1, a telescopic adjustment guide plate 3 disposed at the center of the fixed base plate 1, a plurality of limit bolts 4 evenly and equidistantly arranged on the telescopic adjustment guide plate 3, and fixed posts 5 disposed at the four corners of the bottom of the fixed base plate 1. The sheet metal pressing mechanism 2 includes a pressing mechanism 21, a first guide post 22 disposed on both sides of the pressing mechanism 21, a locking handle 23 disposed below the first guide post 22 at the bottom of the pressing mechanism 21, a sheet metal 24 disposed below the pressing mechanism 21, and the first guide post 22 fixed to the fixed base plate 1. The upper part serves as a guide for the pressing mechanism 21 and is locked and limited by the locking handle 23. The pressing position is adjusted. By setting up a plate pressing mechanism, a telescopic adjustment guide plate, a limit bolt, a fixing column, and other structures, a basic fixture frame suitable for the production of thin gaskets of various diameters is constructed. The plate pressing mechanism can achieve stable pressing and fixing of the plate. The telescopic adjustment guide plate, together with the limit bolt, can be flexibly adjusted according to the diameter of the thin gasket. The fixing column ensures that the fixture is placed stably as a whole. This structural design makes the fixture compatible with plates for the production of thin gaskets of various diameters, improves versatility and production efficiency, and reduces the cost and time loss caused by changing different specifications of fixtures.

[0015] The pressing mechanism 21 includes a fixed plate 211. Guide blocks 212 are provided on both sides of the upper end of the fixed plate 211 and are connected to the first guide post 22 for vertical movement. Two fixed connecting posts 213 are located at the center of the fixed plate 211. Each fixed connecting post 213 has a movable bearing 214 at its lower end, and a guide wheel 215 is positioned between the movable bearings 214. The combined design of the fixed plate, guide blocks, fixed connecting posts, movable bearings, and guide wheels in the pressing mechanism provides precise guidance and stable support for the pressing operation. The connection between the guide blocks and guide posts ensures the accuracy of the vertical movement of the pressing mechanism and avoids... No offset; the fixed connecting column, in conjunction with the movable bearing and guide wheel, reduces frictional resistance when applying pressure to the sheet metal, making the pressing process smoother. Simultaneously, the guide wheel can adaptively adjust its angle according to the sheet metal surface, enhancing adaptability to different sheet metal shapes and improving clamping reliability and stability. The telescopic adjustment guide plate 3 includes a first splicing plate 31, with a second splicing plate 32 disposed on one side of the first splicing plate 31. A plurality of guide holes 33 are equidistantly arranged on the side wall of the first splicing plate 31 near the second splicing plate 32. A plurality of guide holes 33 are arranged at corresponding positions on the second splicing plate 32 at the opposite ends of the guide holes 33. The second guide post 34 is assembled and connected with the guide hole 33. Both the first splicing plate 31 and the second splicing plate 32 are provided with grooves to support plates of different sizes. The telescopic adjustment guide plate uses the first and second splicing plates. Through the assembly of the guide hole and guide post, and the groove design, it effectively supports and quickly adjusts plates of different sizes. This modular splicing structure allows operators to easily adjust the spacing of the guide plates according to the actual size of the thin shims without a complicated disassembly and assembly process, greatly improving the flexibility and ease of use of the fixture and enabling rapid adaptation to thin shims of different specifications. Production task: The first splicing plate 31 and the second splicing plate 32 can be pulled by the cooperation of the guide hole 33 and the second guide post 34, and are simultaneously fixed by the limiting bolt 4; the guide wheel 215 is covered with a rubber anti-slip layer. When the plate 24 is placed under the pressing mechanism 21, the guide wheel 215 contacts the surface of the plate 24, increasing the friction during the application of pressure and preventing the plate 24 from shifting. The rubber anti-slip layer on the guide wheel significantly increases the friction between it and the plate. When applying pressure to the plate for thin gasket production, it can effectively prevent the plate from shifting and ensure the accuracy of the plate position during processing.

[0016] Working Principle: When using this fixture for producing thin gaskets of various diameters, the fixing column 5 is first securely connected to the worktable. The fixing column 5 ensures the overall stability of the fixture during processing, preventing displacement due to vibration. Simultaneously, calibration is performed using the horizontal calibration device (if present) on the fixed base plate 1 to ensure the fixture is level, laying the foundation for precise processing of the thin gaskets. When processing thin gaskets of different diameters, the telescopic adjustment guide plate 3 is adjusted according to the size specifications of the target thin gasket. The operator pulls the first splicing plate 31 or the second splicing plate 32, causing the second guide column 34 to move along... Sliding along the guide hole 33 changes the distance between the first splicing plate 31 and the second splicing plate 32 to accommodate different sized plates 24. After the distance is adjusted, tighten the limit bolt 4 to securely lock the first splicing plate 31 and the second splicing plate 32, ensuring that the groove on the telescopic adjustment guide plate 3 can stably support the plate 24 and prevent the plate from moving laterally during processing. Then, place the plate 24 to be processed into the groove of the telescopic adjustment guide plate 3, and then operate the plate pressing mechanism 2 to fix the plate 24. Turn the locking handle 23 to drive the pressing mechanism 21 to move downward along the first guide post 22. In the middle, the guide blocks 212 on both sides of the fixed plate 211 are tightly engaged with the first guide post 22 to provide precise vertical guidance for the pressing mechanism 21 and prevent deviation during the pressing process. After the guide wheel 215 contacts the surface of the plate 24, the locking handle 23 is rotated to apply pressure. The movable bearing 214 at the lower end of the fixed connecting post 213 plays its role, allowing the guide wheel 215 to make adaptive rotation adjustments at a certain angle according to the undulation and tilt of the surface of the plate 24, ensuring that the guide wheel 215 is fully in contact with the surface of the plate 24 and applying pressure evenly. At the same time, the rubber anti-slip layer on the surface of the guide wheel 215 is in contact with the plate 24. The plate 24 is firmly fixed by close contact and increased friction to prevent displacement under pressure. After the plate 24 is fixed, the production process of the thin gasket can be carried out. Throughout the process, the limit bolt 4 always keeps the telescopic adjustment guide plate 3 tight to ensure that it will not be displaced due to processing vibration or other factors. The locking handle 23 maintains the locked state of the pressing mechanism 21 and continuously and stably applies pressure to the plate 24 to ensure that the plate 24 is fixed in position, thereby ensuring the processing accuracy of the thin gasket. After the processing is completed, the locking handle 23 is released, the pressing mechanism 21 is moved up, and the processed thin gasket and plate 24 are taken out.
