Description

Technical Field

[0001] This utility model belongs to the technical field of sealing components, and in particular relates to an assembly fixture for non-disc-shaped end face sealing components. Background Technology

[0002] Non-disc-type end-face internal and external plug seals require clamps during assembly, mainly because their structure is precise, dimensional tolerances are small, and they are easily deformed. Manual installation makes it difficult to accurately position and control the compression, which can easily lead to positional deviation, uneven stress, or damage to the seal. Clamps, on the other hand, can achieve precise positioning, uniform pressure, and guided installation through customized structures, avoiding interference with surrounding components. They can also adapt to high-precision or complex working conditions, improve efficiency and consistency in mass production, ensure that the seal maintains stable performance after installation, and reduce the risk of leakage and human error.

[0003] However, the outer wall of existing non-disc-shaped end face inner and outer plug seals is usually an irregular arc-shaped outer ring. Existing assembled furniture is not convenient to adjust according to its outer ring, and it is not easy to stably position the seal at the center of the base top. As a result, the seal is prone to shaking before and during assembly, and has poor stability. Utility Model Content

[0004] The purpose of this utility model is to provide an assembly fixture for non-disc-shaped end face inner and outer plug seals, which solves the problem that the outer wall of existing non-disc-shaped end face inner and outer plug seals is usually an irregular arc-shaped outer ring, and existing assembly furniture is not convenient to adjust according to its outer ring, making it difficult to stably position the seal at the center of the top of the base, resulting in the seal easily shaking and poor stability before and during assembly.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an assembly fixture for non-disc-shaped end face inner and outer plug seals, including a base, on which a clamping mechanism and a positioning mechanism are provided; The clamping mechanism includes a motor fixedly connected to the inner wall of the base. The output end of the motor is fixedly connected to a rotating shaft via a coupling. A turntable is fixedly connected to the top of the rotating shaft. Four hinge shafts are fixedly connected to the top surface of the turntable. Hinge rods are rotatably connected to the outer walls of the corresponding three hinge shafts. Four sliding grooves are provided on the top of the base. Movable seats are slidably connected to the inner walls of the corresponding two sliding grooves. The ends of the corresponding two hinge rods away from the hinge shafts are rotatably connected to the sides of the two movable seats that are close to each other. The positioning mechanism includes a second movable seat that is slidably connected to the inner wall of the corresponding slide groove, and the end of the corresponding hinge rod away from the hinge axis is rotatably connected to the front side of the second movable seat.

[0006] Furthermore, two trapezoidal grooves are provided on the side of each of the two movable seats that are close to each other, and trapezoidal sliders are slidably connected to the inner walls of the four trapezoidal grooves. Clamping discs are fixedly connected to the side of each of the four trapezoidal sliders that is away from the trapezoidal grooves.

[0007] Furthermore, each of the four clamping discs has two trapezoidal grooves on its inner wall, and trapezoidal sliders are slidably connected to the inner walls of several trapezoidal grooves.

[0008] Furthermore, each of the trapezoidal sliders is fixedly connected to a clamping frame, and each of the clamping frames is rotatably connected to a positioning roller.

[0009] Furthermore, a connecting block is fixedly connected to the top of the movable seat 2, and a damper is fixedly connected to the front side of the connecting block.

[0010] Furthermore, an L-shaped plate is fixedly connected to one end of the damper away from the connecting block, and a fixing plate is fixedly connected to the top of the base, with the fixing plate located on the front side of the L-shaped plate.

[0011] Furthermore, a spring is wound around the outer wall of the damper, one end of the spring is fixedly connected to the connecting block, and the other end of the spring is fixedly connected to the L-shaped plate.

[0012] This utility model has the following beneficial effects: With the clamping mechanism in place, when the drive motor rotates the shaft and turntable, the two hinged rods work together to make the two moving seats slide closer to each other on the two sliding grooves. This allows multiple positioning rollers to fit against the outer wall of the arc-shaped outer ring of the seal to clamp and fix the seal. The seal can be positioned at the top center of the base, ensuring the stability of the seal before and during assembly, and preventing it from shifting or loosening during subsequent operations. This improves the accuracy and efficiency of the entire assembly process.

[0013] With the positioning mechanism in place, the sliding seat 2 moves forward in cooperation with the slide groove and the second moving seat during the rotation of the turntable. Before the multiple positioning rollers clamp the seal, the L-shaped plate abuts against the rear side of the seal, so that the front side of the seal contacts the fixed plate. As the connecting block continues to move forward, the spring is compressed, and with the damper, the L-shaped plate can firmly press the seal against the fixed plate. In conjunction with the clamping mechanism, this prevents the seal from tilting or shifting during subsequent positioning, further ensuring the accuracy of the assembly process.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
