Description
Technical Field
[0001] This utility model relates to the field of sealing processing technology, specifically a multifunctional positioning tool for sealing processing. Background Technology
[0002] Seal processing refers to the process of transforming raw materials into components with sealing functions through a series of processes. Seal processing involves manufacturing or repairing seals using specific processes and techniques. Seals are widely used in various equipment and systems to prevent liquid or gas leakage, ensuring the normal operation and safety of the system. The processing quality of seals directly affects their sealing performance and service life.
[0003] Positioning fixtures are primarily used to fix and position seals during machining, ensuring they are machined in the correct position to guarantee machining accuracy and stability. These fixtures typically include various positioning elements, such as locating pins and support plates, to ensure the seals do not move or deform during machining.
[0004] When conventional positioning fixtures are used to position and clamp workpieces, the material structure limits their ability to cause unnecessary structural wear on the workpiece surface, thus limiting positioning safety and affecting the workpiece's machining quality. Utility Model Content

The bottom of the stabilizing frame away from the lifting push rod is equipped with the assembly seat.
[0009] Furthermore, the support rod includes a guide rod, a limiting block, and a support base. The top end of the guide rod is fitted with a limiting block, and the bottom end of the guide rod is connected to a support base.
[0010] Furthermore, the inner surface structure of the first docking groove matches the bottom surface structure of the first docking groove, the inner surface structure of the second docking groove matches the bottom surface structure of the support base, the stabilizer and the assembly base are fixedly connected, and the limiting block and the support base are fixedly connected.
[0011] Furthermore, the movable platform assembly includes a platform, a swivel base, and a combination plate. The swivel base is movably mounted on the top of the platform, and the combination plate is provided on the top of the swivel base.
[0012] Furthermore, the docking seat is movably installed on the bottom surface of the platform, and the guide rod slides vertically through the four opposite corners of the platform. The combination plate is movably installed on the bottom surface of the fixed seat. The lifting components and support rods are distributed in a circular array structure with the movable platform assembly as the center, and each is provided in four sets.

This utility model, by installing a set of buffer pads on each of the four vertical side surfaces of the movable gripper, enables the workpiece to be quickly and stably clamped and positioned when the three sets of circularly arranged movable grippers are adjusted horizontally under the operation of the pneumatic control console. The use of buffer pads can ensure the structural stability of the device structure in clamping the workpiece, ensuring sufficient clamping friction, and can also avoid unnecessary structural wear or extrusion on the surface of the workpiece when the movable gripper clamps the workpiece, thereby ensuring the stability and clamping safety of the entire positioning component.
[0016] 2. This utility model, by setting a lifting component and a movable platform component at the bottom of the positioning component, allows the movable platform component and positioning component connected at the top to be adjusted vertically within a certain range by utilizing the structural operation of the lifting push rod. The operation of the rotary seat can drive the entire positioning component connected at the top to be adjusted axially in the vertical direction. By using the above-mentioned structural design, the operational flexibility and convenience of the device structure can be ensured as much as possible, thereby assisting the processing equipment in processing the workpiece and ensuring the processing quality of the workpiece.
[0017] 3. This utility model combines the base component, lifting component, support rod, movable platform component, and positioning component into a modular structure. Utilizing the modularity and ease of assembly and disassembly, each component offers both structural stability and flexible disassembly, facilitating maintenance. Furthermore, support rods are vertically inserted through the four diagonal points of the movable platform component, with their bottoms fixed to the base component. This design allows the platform to slide synchronously along the guide rod surface during vertical lifting of the movable platform component. The support rods provide both structural guidance and support, ensuring the stability of the device's operational adjustments. Attached Figure Description
