Description

Technical Field

[0001] This utility model relates to the field of MPP pipe processing technology, specifically a variable diameter MPP pipe processing fixture. Background Technology

[0002] MPP pipe processing refers to the entire process of transforming MPP resin as the core raw material into MPP pipes and related products with specific specifications, performance, and uses through a specific process. In order to assist in the stable clamping of MPP pipes of different sizes during the MPP pipe processing, a variable diameter MPP pipe processing fixture is needed.

[0003] Traditional MPP pipe processing fixtures typically place the MPP pipe on a processing platform and then use a threaded rod to rotate and move a clamping plate on the platform to hold the MPP pipe and assist in processing. However, traditional devices are difficult to adapt to the diameter of the MPP pipe while preventing the pipe from shifting position, which could affect the stable operation of the device.

[0006] As a preferred embodiment of this utility model, a sliding rod is fixedly sleeved on the inner wall of the sliding cylinder, an inner cylinder is slidably sleeved on the outer edge of the sliding rod, the outer edge of the inner cylinder is slidably sleeved with the inner wall of the sliding cylinder, the side of the sliding rod is fixedly assembled with the side of the side plate, and a spring is fixedly connected to the side of the outer cylinder, with the end of the spring away from the outer cylinder fixedly connected to the side of the side plate.

[0007] As a preferred embodiment of this utility model, a first magnetic ring is fixedly sleeved on the inner wall of the outer cylinder, and a second magnetic ring is fixedly assembled on the side of the sliding cylinder, with the second magnetic ring repelling the side adjacent to the first magnetic ring.

[0008] As a preferred technical solution of this utility model, a circular groove is provided on the side of the inner wall of the rotating frame, and a rotating rod is rotatably connected to the side of the inner wall of the circular groove. The side of the rotating rod is fixedly assembled with the side of the side clamping plate. A torsion spring is provided on the outer edge of the rotating rod. One end of the torsion spring is fixedly connected to the inner wall of the circular groove, and the end of the torsion spring away from the inner wall of the circular groove is fixedly connected to the side of the side clamping plate.

[0009] As a preferred technical solution of this utility model, an auxiliary plate is fixedly assembled at the bottom of the fixed plate, a positioning cylinder is fixedly assembled on the side of the auxiliary plate, a second spring is fixedly connected to the side of the inner wall of the positioning cylinder, and a positioning protrusion is fixedly connected to the end of the second spring away from the inner wall of the positioning cylinder, and the outer edge of the positioning protrusion is slidably sleeved with the inner wall of the positioning cylinder, and the shape and size of the convex surface of the positioning protrusion are adapted to the shape and size of the concave surface of the positioning groove.

[0010] As a preferred embodiment of this utility model, a base is fixedly mounted on the bottom of the fixing plate, a U-shaped frame is fixedly mounted on the inner wall of the base, and the top of the U-shaped frame is fixedly mounted to the bottom of the fixing plate. A self-locking motor is fixedly mounted on the bottom of the inner wall of the base, and the output shaft of the self-locking motor is fixedly sleeved with the inner wall of the positioning wheel.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This variable diameter MPP pipe processing fixture uses a toothed plate and a side plate in cooperation. The self-locking motor drives the gear to rotate through the positioning wheel, and then the gear drives the toothed plate to slide in the inner wall of the slide groove. The side plate drives the inner wall of the arc-shaped clamping plate to clamp and limit the outer edge of the MPP pipe. The rotating rod and the torsion spring drive the side clamping plate to rotate in the inner wall of the rotating frame, thereby assisting the side clamping plate to overlap with the outer edge of the MPP pipe, and further assisting the clamping and limiting of the MPP pipe. When the MPP tube vibrates during processing, the outer edge of the slide rod slides in the inner wall of the inner cylinder, the outer edge of the slide cylinder slides in the inner wall of the outer cylinder, and the inner wall of the slide cylinder slides in the outer edge of the inner cylinder. This causes the slide cylinder to move the second magnet ring towards the first magnet ring, thereby using the repulsion between the first and second magnet rings to assist in damping the MPP tube and ensuring stable clamping and limiting of the MPP tube.

[0012] 2. This variable-diameter MPP pipe processing fixture uses a self-locking motor and a positioning wheel in conjunction. The self-locking motor drives the positioning wheel to rotate, which in turn uses gears to adjust the position of the arc-shaped clamping plate. Once the arc-shaped clamping plate is in the desired position, the self-locking motor is turned off. Then, a spring pushes the positioning protrusion in the inner wall of the positioning cylinder to move. The convex surface of the positioning protrusion then aligns with the inner wall of the positioning groove, thus assisting the positioning wheel in limiting the position while also limiting the arc-shaped clamping plate. This ensures stable clamping of the MPP pipe and prevents it from becoming loose. Attached Figure Description

The outer edge of the positioning protrusion 24 is slidably sleeved with the inner wall of the positioning cylinder 22.

Through the cooperation of the spring 23 and the positioning protrusion 24, the spring 23 pushes the positioning protrusion 24 to move in the inner wall of the positioning cylinder 22, and then the convex surface of the positioning protrusion 24 contacts the concave surface of the positioning groove 20, thereby assisting the positioning wheel 19 to drive the gear 2 to perform limiting.

[0021] In a preferred embodiment, a base 26 is fixedly mounted on the bottom of the fixing plate 1, a U-shaped frame 27 is fixedly mounted on the inner wall of the base 26, and the top of the U-shaped frame 27 is fixedly mounted on the bottom of the fixing plate 1.

[0022] Working principle: When the device is in use, the self-locking motor 25 drives the positioning wheel 19 to rotate, which in turn drives the gear 2 to rotate within the inner wall of the fixed plate 1. The gear 2 then drives the toothed plate 3 to slide within the inner wall of the fixed plate 1. The toothed plate 3, through the side plate 5, moves the arc-shaped clamping plate 13 until its inner wall clamps and limits its movement against the outer surface of the MPP tube. The torsion spring 17, in conjunction with the rotating rod 16, causes the side clamping plate 18 to come into close contact with the outer edge of the MPP tube. Afterwards, the self-locking motor 25 is turned off, and the spring 23, within the positioning cylinder 22... The positioning protrusion 24 is pushed to move in the inner wall, and the convex surface of the positioning protrusion 24 is connected with the concave surface of the positioning groove 20 to assist the positioning wheel 19 in limiting its position. When the MPP tube body shakes during processing, the outer edge of the sliding rod 6 slides in the inner wall of the inner cylinder 9, and the outer edge of the sliding cylinder 7 slides in the inner wall of the outer cylinder 8. The inner wall of the sliding cylinder 7 slides on the outer edge of the inner cylinder 9, and the sliding cylinder 7 drives the second magnet ring 11 to move closer to the first magnet ring 10. The adjacent surfaces of the first magnet ring 10 and the second magnet ring 11 repel each other, thereby assisting in shock absorption.
