[0002] Silicone gaskets are sealing components used in machinery, equipment, pipelines, and anywhere fluid is present. They are used both internally and externally to provide a seal. Gaskets are manufactured through processes such as cutting, stamping, or trimming, and are used for sealing connections between pipes and between machine parts.

[0003] A patent search revealed a titled "Positioning Fixture for Processing Silicone Sealing Gaskets" (publication number "CN222644300U"). This published document describes a device that uses limiting strips, limiting plates, and springs to limit the material. The spring's rebound force clamps and positions the material laterally. However, since the material is silicone, which is known to be flexible, the lateral clamping causes wrinkling due to compression, affecting the flatness of the material after positioning and consequently impacting the accuracy of subsequent processing. Therefore, this invention designs a positioning fixture for processing silicone sealing gaskets to solve the aforementioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1 A preferred embodiment of the positioning fixture for processing silicone gaskets provided by this utility model is as follows: Figures 1 to 4 As shown: A positioning fixture for processing silicone sealing gaskets includes a base plate 1; a bracket 2 fixed on the top left side of the base plate 1; a pressure frame 3 disposed inside the bracket 2; a rotating rod 4 rotatably disposed on the upper end inside the bracket 2; a slide 5 slidably disposed inside the base plate 1; and a drive assembly 6 assembled on the outside of the base plate 1, the drive assembly 6 controlling the slide 5 to move in the transverse direction along the base plate 1.

[0022] The slide 5 and the pressure frame 3 have a U-shaped cross-section in side view. The pressure frame 3 is slidably connected to the bracket 2. The rotating rod 4 is threaded through the pressure frame 3. The drive assembly 6 includes a first motor 601 fixed on the right side of the outside of the base plate 1; a rotating shaft 602 fixedly installed on the left side of the first motor 601, and the rotating shaft 602 rotates through the base plate 1. The rotating shaft 602 is threaded through the slide 5.

[0023] It should be noted that existing positioning fixtures for processing silicone gaskets can cause wrinkles in the silicone material when positioning it, affecting the flatness of the material and thus the accuracy of subsequent processing.

[0024] In this embodiment, the base plate 1 is installed on the workbench of the sealing gasket cutting machine. The operator places a rectangular strip of silicone material on the base plate 1, with the left end of the material at the bottom of the pressure frame 3. At this time, the material is in a flat position. The operator then rotates the rotating rod 4. Through the threaded transmission design between the rotating rod 4 and the pressure frame 3, the pressure frame 3 applies clamping force to the left end of the material. The operator then turns on the first motor 601, which controls the rotating shaft 602 to rotate. Through the threaded transmission design between the rotating shaft 602 and the slide 5, the slide 5 moves along the lateral direction of the base plate 1. In this way, the slide 5 and the support 2 can be matched and used with materials of different lengths.

[0025] In a further preferred embodiment of this utility model, a limiting component 7 is assembled on the outside of the slide 5. The limiting component 7 can position the material to be processed on the silicone sealing gasket placed on the top of the base plate 1. The limiting component 7 includes an electric push rod 701 fixedly mounted on the top of the slide 5, and the output end of the electric push rod 701 slides through the slide 5; a pressure plate 702 is fixedly installed at the bottom of the output end of the electric push rod 701, and the pressure plate 702 is slidably connected to the slide 5. A controller 8 is fixedly mounted on the outer wall of the bracket 2. The controller 8 is connected to the first motor 601 and the electric push rod 701 through a wire.

[0026] In this embodiment, when the carriage 5 moves to the right end area of ​​the material, the motor is turned off first, and then the electric push rod 701 is turned on. The electric push rod 701 controls the pressure plate 702 to clamp the right end of the material. In this way, the flat material is positioned and clamped.

[0027] Example 2 Based on Example 1, a preferred embodiment of the positioning fixture for processing silicone sealing gaskets provided by this utility model is as follows: Figures 1 to 4As shown: The slide 5 has pivot pins 9 connected to its front and rear ends. A connecting rod 10 is fixed to the outer wall of the pivot pin 9. A rolling sleeve 11 is rotatably fitted onto the outer side of the connecting rod 10. A mounting frame 12 is fixed to the right side of the slide 5. A placement rod 13 is connected inside the mounting frame 12. The placement rod 13 is parallel to the pivot pin 9. Sprockets 14 are fixedly fitted to the front and rear ends of the placement rod 13 and the outer side of the pivot pin 9. A chain 15 is meshed with the outer teeth of the sprockets 14. An adjustment assembly is provided outside the mounting frame 12. The adjustment assembly controls the placement rod 13 to rotate in conjunction with the pivot pin 9. The adjustment assembly includes a second motor 16 fixed to the outside of the mounting frame 12; a worm gear 17 fixedly installed to the right of the second motor 16, and the worm gear 17 is rotatably connected to the mounting frame 12; and a worm wheel 18 with meshing teeth on the outside of the worm gear 17. The worm gear 17 and the placement rod 13 are designed to be perpendicular to each other. The second motor 16 is connected to the controller 8 via a wire. The worm wheel 18 is fixedly fitted onto the outside of the placement rod 13.

[0028] In this embodiment, after the left end of the material is clamped, the operator first turns on the second motor 16. The second motor 16 drives the worm gear 17 to drive the worm wheel 18 to rotate the placement rod 13 together with the sprocket 14, chain 15, pivot pin 9, connecting rod 10 and roller sleeve 11 until the roller sleeve 11 is in close contact with the top surface of the material. Then, the second motor 16 is turned off and the first motor 601 is turned on. The first motor 601 moves the slide 5 and roller sleeve 11 along the right side of the base plate 1. At this time, the roller sleeve 11 is in a state of friction with the material, which causes the roller sleeve 11 to smooth the material.

[0029] In summary, the pressure frame and pressure plate in this application can clamp and position materials in the longitudinal direction, ensuring the flatness of the materials. The displacement function design allows the pressure plate and pressure frame to be used with materials of different lengths. The adjustment function design places the rollers and materials in a state of rolling friction during displacement, thereby allowing the rollers to smooth the materials and further improving their flatness.
