Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling for pipe and valve assembly, specifically, to a top-pressing mechanism for pipe and valve assembly. Background Technology

[0002] Pipe valves are devices that combine the functions of connectors, plugs, and shut-off valves in a water supply system. They consist of components such as screw plugs, return valve sleeves, pistons, valve seats, and inlet valve sleeves. During pipe valve assembly, because some components need to be suspended in the air, a pressure-pressing mechanism is often used to press the components together for assembly. However, existing pressure-pressing mechanisms can only press one component at a time, requiring users to feed different components multiple times, making the pressure-pressing process cumbersome and inconvenient.

[0003] Utility model patent CN222582237U discloses a rotor assembly fixture for an air conditioner motor, including a worktable and several molds. An electric push rod is fixedly connected to the upper surface of the worktable, and a top plate is fixedly connected to the output end of the electric push rod. An iron core and a rotating shaft are engaged with the inner wall of the molds. An adjustment structure is provided on the surface of the worktable, including a rotating rod rotatably connected to the worktable, with a rotating plate fixedly connected to the upper end of the rotating rod. This rotor assembly fixture for an air conditioner motor, through its adjustment structure, allows the rotating plate to move the rotating shaft and iron core during rotor assembly. The top plate then presses the rotating shaft, causing it to insert into the iron core along the inner wall of the mold, thus completing the rotor assembly. During this process, the worker's hands do not need to be placed between the top plate and the molds, thus avoiding hand injuries and eliminating safety hazards. However, because this rotor assembly fixture for an air conditioner motor involves horizontal pressing, it is not suitable for assembling pipes and valves that require vertical assembly processes.

[0016] The feeding tray is slidably mounted on the square rod. The feeding tray has several circular inclined slots for placing the parts to be assembled. The clamping assembly is disposed on the feeding tray and located on both sides of the circular inclined slots.

[0017] The lower end of the square rod is mounted on the base, and the upper end of the square rod passes through the receiving plate. The square rod is used to drive the feeding tray to rotate.

[0018] Based on the above, the lower surface of the feeding tray slides in conjunction with the upper surface of the receiving plate.

[0021] The guide rod is connected to the feeding tray, the tension spring is sleeved on the guide rod, and the outer end of the tension spring is connected to the positioning plate.

[0022] Based on the above, in order to prevent the parts from shifting, magnetic pads are provided on the inner side of the positioning plate.

[0023] Based on the above, a rubber ring is provided in the circular inclined groove for elastically supporting the part to be assembled.

[0024] Based on the above, the receiving plate is provided with an assembly clearance hole and a square rod assembly hole for the square rod to pass through. The assembly clearance hole is arranged vertically and vertically corresponding to the top pressure cylinder and the clamping fixing seat.

By utilizing the upward movement of the lifting frame and the rotational movement of the loading tray, the parts to be assembled on the loading tray are pressed one by one onto the most basic component, thereby simplifying the assembly process and improving the practicality of the device.

[0026] Furthermore, by setting guide rods, positioning plates, and tension springs, after the component is placed inside the circular inclined groove, the tension springs drive the positioning plates to move closer to each other, thereby further clamping and fixing the position of the component, making its top pressure movement more stable and improving the stability of the device.

[0027] Therefore, this type of pressure-pressing mechanism for pipe valve assembly can perform multiple pressure presses during pipe valve assembly and can adjust the pressure-pressing stroke. Attached Figure Description

[0050] This embodiment provides a top-pressing mechanism for valve assembly. The main difference from Embodiment 1 is that, in this embodiment, to prevent parts from shifting, magnetic pads 19 are provided on the inner side of the positioning plate 15. A rubber ring 11 for elastically supporting the parts to be assembled is provided inside the circular inclined groove 10. Mounting plates 21 are provided on both sides of the base 1, and mounting grooves 22 are formed on the mounting plates.

[0051] Example 5

[0052] This embodiment provides a top-pressing mechanism for valve assembly. The main difference from Embodiment 1 is that, in this embodiment, an inverted L-shaped connecting frame 26 is provided on the lifting frame.
