[0016] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 3 It can be seen that a plastic tube punching device includes a frame 1, a punching mechanism is slidably arranged on the frame 1, a plurality of brackets 2 are arranged on both sides of the frame 1, support rods 3 are telescopically arranged on the brackets 2, and the support rods 3 on both sides are always symmetrical about the vertical plane where the punching mechanism is located, a fixed plate 4 is provided at the end of the frame 1, a fixed rod 5 is vertically slidably arranged on the fixed plate 4, a plurality of groups of pressure rods 6 are provided on the fixed rod 5, the pressure rods 6 cooperate with the support rods 3 to fix the plastic tube, and then the punching mechanism punches holes in the plastic tube from below.

[0018] When the utility model is used in a specific way,

[0019] Adjust the position of the support rod 3 according to the size of the plastic tube, and then place the plastic tube on the support rod 3. The support rods 3 on both sides are always symmetrical about the punching position. Therefore, the center line of the plastic tube is above the punching position. Insert the fixing rod 5 into the plastic tube, and press the plastic tube against the support rod 3 after the pressing rod 6 moves downward to fix the position of the plastic tube. Then start the punching mechanism to complete the punching of the plastic tube from the bottom.

[0020] A horizontal slide groove 7 is provided on the frame 1, and a lead screw 8 is provided in the horizontal slide groove 7. The lead screw 8 is driven by a motor 9 located at the end. When the plastic tube is fixed, one end contacts the fixed plate 4. The punching position can be displaced by controlling the rotation of the lead screw 8 by the motor 9, thereby moving the punching mechanism to a suitable and precise punching position.

[0021] The punching mechanism includes a first slider 10 sliding in a horizontal slide groove 7, an electric drill 11 is vertically slidably arranged inside the first slider 10, the electric drill 11 is driven to rise and fall by a first hydraulic cylinder 12, a mounting plate 13 is provided under the first slider 10, the mounting plate 13 and the first slider 10 are connected to each other by the first hydraulic cylinder 12 for lifting and lowering, a connecting rod 14 is provided between the mounting plate 13 and the electric drill 11, and the electric drill 11 is vertically facing upward.

[0022] After the first slider 10 moves to the accurate position, the first hydraulic cylinder 12 drives the electric drill 11 to rise to complete the drilling of the plastic tube. There is a certain distance between the electric drill 11 and the mounting plate 13, so that the electric drill 11 can be lifted to a very high height to complete the drilling of the plastic tube.

[0023] The support rod 3 is L-shaped, and a first ball 15 is provided at the end of the support rod 3. The first ball 15 is higher than the top of the bracket 2. The support rod 3 is telescopically arranged on the bracket 2 through a second hydraulic cylinder 16. The support rods 3 on both sides are simultaneously controlled to be telescopically extended by the second hydraulic cylinder 16, and are always symmetrical. The first ball 15 at the top of the support rod 3 contacts the outer wall of the plastic tube to support the plastic tube, and can adapt to plastic tubes of various specifications.

[0024] A vertical slide groove 17 is provided on the fixed plate 4, and a second slider 18 is slidably arranged in the vertical slide groove 17. The second slider 18 is lifted and lowered by a third hydraulic cylinder 19. The fixed rod 5 is telescopically arranged on the second slider 18 by a fourth hydraulic cylinder 20. The third hydraulic cylinder 19 controls the lifting and lowering of the second slider 18, so that the height can be adapted to plastic pipes of different diameters. The fixed rod 5 is telescopically controlled by the fourth hydraulic cylinder 20, so that the pressure rod 6 can be moved a certain distance along the axial direction, so as to be staggered with the position of the electric drill 11 to avoid affecting the drilling.

[0025] Each group of pressure rods 6 includes two and is symmetrical about the vertical plane. The pressure rods 6 are telescopically arranged inside the fixed rod 5. A second ball 21 is provided at the end of the pressure rod 6. A spring 22 is sleeved on the pressure rod 6. The spring 22 pushes the pressure rod 6 outward. The pressure rod 6 is pushed outward by the spring 22. When the plastic tube is compressed, the spring 22 is in a compressed state. The pressure rod 6 is tightly pressed against the inner wall of the plastic tube. Due to the telescopic effect of compression, the pressure rod 6 can be adapted to plastic tubes with different inner diameters.

[0026] When drilling, since the drilling position and the axis of the plastic tube are in the same vertical plane, the plastic tube will not rotate, ensuring stability during drilling. When multiple drilling positions are not in the same plane, the plastic tube can be rotated. Since the inner and outer contact points of the plastic tube are both balls, it is easy to rotate.

[0027] Compared with the prior art, the utility model has the following beneficial effects: the plastic tube does not need to be marked after being fixed, the punching position can be controlled according to the rotation of the lead screw to ensure the accuracy of the punching position, and multiple holes can be punched at one time without repeated marking, which greatly improves the punching efficiency.
