[0014] The utility model will be described in detail below in combination with the drawings.
[0015] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the utility model will be described in further detail below in combination with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.
[0016] Refer to Figs. 1-3This utility model provides a screwing and assembly device for plastic conduits, comprising a mounting block 1, a support block 2 horizontally mounted on the mounting block 1, a first slider 4 driven by a first cylinder 3 sliding laterally on the support block 2, and a second slider 6 driven by a second cylinder 5 sliding vertically on the first slider 4. The first cylinder 1 is a long-stroke cylinder, providing sufficient movement space. The third cylinder 8 is a two-jaw cylinder used to grip the plastic conduit. A polygonal shape resembling a nut is provided in the middle of the outer wall of the plastic conduit. A servo motor 7 is mounted downwards on the second slider 6, and the output shaft of the servo motor 7 is connected to the third cylinder 8. The servo motor can precisely control the rotation angle and speed, achieving precise screwing operations according to the specific requirements of plastic conduit assembly. It ensures uniform screwing force and speed and allows flexible adjustment of the third cylinder in the horizontal and vertical directions, realizing automated control of multiple actions such as gripping, moving, and screwing. This reduces manual intervention, lowers labor intensity, and improves production efficiency and product quality consistency. The second cylinder drives the second slider to move down and then up, causing the third cylinder to clamp the plastic tube. The first cylinder drives the first slider to move to the left, causing the third cylinder to clamp the plastic tube above the plastic nut. The second cylinder then drives the second slider to move down, and the servo motor drives the third cylinder and the plastic tube to rotate, causing the plastic tube to tighten the plastic nut. Then the third cylinder releases the plastic tube, the second cylinder drives the second slider and its components to rise and reset, and the third cylinder drives the first slider and its components to move to the right and reset.
[0017] The frame block 2 is concave in shape, and a horizontal slide rail 9 is provided on the frame block 2 to accommodate the sliding of the first slider 4. The first slider slides on the horizontal slide rail, and the first cylinder drives the first slider to move left and right, ensuring that the first slider and its components slide precisely left and right.
[0018] The second slider 6 is L-shaped, and a longitudinal slide rail 10 is provided on the first slider 4 to accommodate the sliding of the second slider 6. The second slider slides on the longitudinal slide rail, and the second cylinder drives the second slider to move up and down, ensuring that the second slider and its components slide up and down precisely.
[0019] A fixing block 11 is horizontally mounted at the lower end of the second slider 6, and the third cylinder 8 rotates on the fixing block 11. The fixing block allows the third cylinder to rotate stably and reliably. The output shaft of the servo motor is thin and long, and cannot support the weight of the third cylinder, making it prone to wobbling.
[0020] See Fig. 1 , Fig. 2 The frame block 2 is equipped with adjustable limiting bolts 12 on both sides for limiting the first slider 4. The limiting bolts can be adjusted left and right as needed, and can limit the first slider and its components to the left and right to determine the stroke.
[0021] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
