Description

Technical Field

[0001] This utility model relates to the technical field of polytetrafluoroethylene (PTFE) product manufacturing and processing equipment, and in particular to an adjustable PTFE inner diameter sintering fixture for tank trucks. Background Technology

[0002] The PTFE inner diameter of a tank truck refers to the inner wall portion of the PTFE liner attached to the metal tank of a tanker truck through a sintering process. This PTFE liner possesses excellent corrosion resistance, high-temperature resistance, non-stick properties, and insulation, ensuring the purity and safety of transported materials. The processing of the PTFE inner diameter relies on sintering fixtures. The sintering of the PTFE liner needs to be carried out under specific temperature and pressure conditions, ensuring a tight fit between the liner and the metal tank. Without specialized fixtures for fixing and positioning, the PTFE material is prone to shrinkage, deformation, or displacement during high-temperature sintering. Tank trucks come in various specifications, and the PTFE inner diameter must precisely match the tank size. Sintering fixtures can be structurally adjusted to adapt to different tank sizes, ensuring consistency in the inner diameter after sintering and avoiding dimensional deviations caused by human error.

[0003] In practical use, traditional adjustable tank truck PTFE inner diameter sintering fixtures may require workers to reach into the tank to manually disassemble the fixing structure and then drag the fixture out of the tank as a whole. This not only results in a small operating space and extremely difficult positioning for manual operation, but also makes it easy for the fixture to get stuck in the tank due to uneven force, increasing the difficulty of removal. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable polytetrafluoroethylene inner diameter sintering fixture for tank trucks, which aims to improve the problem of limited operating space and extremely difficult positioning for manual operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable sintering fixture for polytetrafluoroethylene (PTFE) inner diameter in a tank truck, comprising a support, an inclined plate fixedly connected inside the support, a protective shell fixedly connected to the outer wall of the support, a tank body slidably connected to the outer wall of the protective shell, a fixed plate slidably connected to the outer wall of the tank body, an electric push rod fixedly connected to the outer wall of the fixed plate, a connecting frame fixedly connected to the output end of the electric push rod, a round-headed rod rotatably connected to the outer wall of the connecting frame, a swing rod rotatably connected to the outer wall of the round-headed rod, a clamping ring fixedly connected to the outer wall of the swing rod, and a sintering assembly fixedly connected to the outer wall of the support, the sintering assembly being used for sintering polytetrafluoroethylene.

[0006] The above technical solution first activates the electric push rod to move the connecting frame, which in turn moves the round-headed rod, which in turn moves the swing arm, thus pulling out the sintered fixing plate and sliding it out along the surface of the inclined plate. This reduces the difficulty of positioning during manual operation and prevents workpiece displacement. When it is necessary to sinter the unsintered fixing plate, the fixing plate is pushed into the protective shell, and the electric push rod is activated to move the connecting frame, which in turn moves the clamping ring to fix the fixing plate. The bracket restricts the sintering assembly, ensuring that the position of the sintering assembly does not change.

[0007] Preferably, the sintering assembly includes a second electric push rod, the outer wall of which is fixedly connected to the outer wall of the support, and the output end of the second electric push rod is fixedly connected to a sintering nozzle.

[0008] Preferably, the outer wall of the swing arm is rotatably connected to the outer wall of the fixed plate, and the outer wall of the connecting frame is slidably connected to the outer wall of the fixed plate.

[0009] Preferably, the outer wall of the tank is slidably connected to the outer wall of the fixing plate, and the outer wall of the clamping ring is slidably connected to the outer wall of the fixing plate.

[0010] Preferably, a motor is fixedly connected to the outer wall of the protective shell, and a gear one is fixedly provided at the output end of the motor. The tooth end of the gear one meshes with a gear ring, the tooth end of the gear ring meshes with a gear two, and the tooth end of the gear ring meshes with a gear three.

[0011] Preferably, the outer wall of gear two is rotatably connected to the inside of the protective shell, and the outer wall of gear three is rotatably connected to the inside of the protective shell.

[0012] Preferably, the outer wall of the gear is rotatably connected to the inside of the protective shell, and the outer wall of the gear ring is fixedly connected to the outer wall of the fixing plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, starting the electric push rod drives the connecting frame to move, which in turn drives the round-headed rod to move, thereby driving the swing arm to move, and then pulling out the sintered fixed plate, which slides out along the surface of the inclined plate. This can reduce the positioning difficulty of manual operation and also prevent the workpiece from shifting.

[0015] 2. In this utility model, the starting motor drives gear one to rotate, which in turn drives the gear ring to rotate, thereby driving gear two and gear three to rotate. The fixed plate rotates synchronously, making the inner diameter of the polytetrafluoroethylene inside the fixed plate more uniform during sintering. This can prevent uneven sintering temperature and also expand the functional boundaries of the tooling. Attached Figure Description

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: an adjustable sintering fixture for polytetrafluoroethylene (PTFE) inner diameter in a tank truck, comprising a support 1, an inclined plate 2 fixedly connected inside the support 1, a protective shell 3 fixedly connected to the outer wall of the support 1, a tank body 4 slidably connected to the outer wall of the protective shell 3, a fixed plate 5 slidably connected to the outer wall of the tank body 4, an electric push rod 6 fixedly connected to the outer wall of the fixed plate 5, a connecting frame 7 fixedly connected to the output end of the electric push rod 6, a round-headed rod 8 rotatably connected to the outer wall of the connecting frame 7, a swing rod 9 rotatably connected to the outer wall of the round-headed rod 8, a clamping ring 10 fixedly connected to the outer wall of the swing rod 9, and a sintering assembly fixedly connected to the outer wall of the support 1, the sintering assembly being used for sintering polytetrafluoroethylene;

[0024] Specifically, firstly, the electric push rod 6 is activated to move the connecting frame 7, which in turn moves the round-headed rod 8. The fixed plate 5 restricts the electric push rod 6, ensuring its position remains unchanged under external force. The connecting frame 7 restricts the round-headed rod 8, ensuring that the connecting frame 7 moves simultaneously with the round-headed rod 8 when driven by the electric push rod 6, thereby moving the swing rod 9. The fixed plate 5 also restricts the swing rod 9, ensuring it remains in the same position and performs circular motion when driven by the round-headed rod 8. This pulls out the sintered fixed plate 5, which slides along the surface of the inclined plate 2. This reduces the difficulty of manual positioning and prevents workpiece displacement. When the unsintered fixed plate 5 needs to be sintered, it is pushed into the protective shell 3, and the electric push rod 6 is activated to move the connecting frame 7, which in turn moves the clamping ring 10 to fix the fixed plate 5. The bracket 1 restricts the sintering assembly, ensuring its position remains unchanged.

[0025] Reference Figure 2 The sintering assembly includes an electric push rod 11, the outer wall of which is fixedly connected to the outer wall of the bracket 1, and the output end of the electric push rod 11 is fixedly connected to a sintering nozzle 12.

[0026] Specifically, bracket 1 restricts the electric push rod 11 to ensure that the position of the electric push rod 11 does not change during operation. When used with toothed ring 15, it can achieve uniform sintering of the inner lining and achieve the effect of sintering and cooling at the same time.

[0027] Reference Figure 1 and Figure 3 The outer wall of the swing arm 9 is rotatably connected to the outer wall of the fixed plate 5, and the outer wall of the connecting frame 7 is slidably connected to the outer wall of the fixed plate 5.

[0028] Specifically, the fixing plate 5 restricts the swing arm 9 so that the swing arm 9 always rotates in the same position when driven by the round head rod 8. The fixing plate 5 also restricts the connecting frame 7 to ensure that the connecting frame 7 will not fall off when driven by the electric push rod 6.

[0029] Reference Figure 1 and Figure 3 The outer wall of the tank body 4 is slidably connected to the outer wall of the fixed plate 5, and the outer wall of the clamping ring 10 is slidably connected to the outer wall of the fixed plate 5.

[0030] Specifically, the fixing plate 5 restricts the tank body 4, making the positioning of the tank body 4 more accurate when it is pulled out or pushed in. The fixing plate 5 also restricts the clamping ring 10, ensuring that the clamping ring 10 and the fixing plate 5 work together to make the positioning more accurate.

[0031] Reference Figure 4A motor 13 is fixedly connected to the outer wall of the protective shell 3. A gear 14 is fixedly installed at the output end of the motor 13. A gear ring 15 meshes with the tooth end of the gear 14. A gear 2 16 meshes with the tooth end of the gear ring 15. A gear 3 17 meshes with the tooth end of the gear ring 15.

[0032] Specifically, the motor 13 is first started to drive the gear 14 to rotate, which in turn drives the gear ring 15 to rotate. The protective shell 3 restricts and supports the motor 13 and the gear 14 to ensure that their positions do not change. The fixing plate 5 restricts the gear ring 15 to ensure that the gear ring 15 rotates synchronously with the fixing plate 5, thereby driving the gear 16 and gear 17 to rotate. Since the gear ring 15 meshes with the gear 16 and gear 17, the gear ring 15 rotates synchronously with the gear 16 and gear 17. Since the fixing plate 5 is fixed by the clamping ring 10, the synchronous rotation of the fixing plate 5 makes the inner diameter of the polytetrafluoroethylene inside the fixing plate 5 more uniform during sintering, which can prevent uneven sintering temperature and also expand the functional boundaries of the tooling.

[0033] Reference Figure 4 The outer wall of gear 2 16 is rotatably connected to the inside of protective shell 3, and the outer wall of gear 3 17 is rotatably connected to the inside of protective shell 3;

[0034] Specifically, the protective shell 3 restricts gear 2 16 to ensure that the position of gear 2 16 does not change, and the protective shell 3 restricts gear 3 17 to ensure that the position of gear 3 17 does not change.

[0035] Reference Figure 4 The outer wall of gear 14 is rotatably connected to the inside of the protective shell 3, and the outer wall of gear ring 15 is fixedly connected to the outer wall of the fixing plate 5.

[0036] Specifically, the protective shell 3 restricts the gear 14 to ensure that the position of the gear 14 does not change when subjected to force, and the fixing plate 5 restricts the gear ring 15 to ensure that the gear ring 15 can synchronously drive the fixing plate 5 to rotate when driven by the gear 14.

[0037] Working principle: When it is necessary to remove the sintered workpiece, the electric push rod 6, which is restricted by the fixed plate 5, is first activated to move the connecting frame 7, which in turn moves the round-head rod 8, thereby moving the swing rod 9, and pulling out the sintered fixed plate 5, which slides out along the surface of the inclined plate 2. This can reduce the positioning difficulty of manual operation and prevent the workpiece from shifting. When it is necessary to sinter the unsintered fixed plate 5, the fixed plate 5 is pushed into the interior of the protective shell 3, and the electric push rod 6 is activated to move the connecting frame 7, thereby moving the clamping ring 10 to fix the fixed plate 5.

[0038] When the inner diameter of the polytetrafluoroethylene inside the fixed plate 5 begins to sinter, the motor 13 is started first to drive the gear 14 to rotate, which in turn drives the gear ring 15 to rotate, thereby driving the gear 16 and gear 17 to rotate. The fixed plate 5 rotates synchronously, making the inner diameter of the polytetrafluoroethylene inside the fixed plate 5 more uniform during sintering. This can prevent uneven sintering temperature and also expand the functional boundaries of the tooling.

[0039] This sintering fixture can reduce the difficulty of positioning during manual operation, prevent workpiece displacement, prevent uneven sintering temperature, and expand the functional boundaries of the fixture.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
