Description

Technical Field

[0001] This utility model relates to the field of plastic pipe processing technology, and in particular to a positioning structure for drilling holes in plastic pipes. Background Technology

[0002] Some customers order custom-made plastic pipes that require drilling for connection during construction. In existing technology, the plastic pipe is fixed in place before drilling is done using a drilling device. However, existing devices are generally designed for smaller diameter plastic pipes. Larger diameter plastic pipes are difficult to fix in the device, so a handheld drilling device is needed to drill holes in the plastic pipe.

[0003] This method can lead to inaccurate positioning, poor drilling quality, and even damage to the plastic tube. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a positioning structure for drilling holes in plastic pipes, which effectively solves the problem of inconvenient drilling of large-diameter plastic pipes.

[0005] The technical solution to the problem is: a positioning structure for drilling holes in plastic pipes, including a fixing plate, an mounting plate connected to the bottom of the fixing plate, a pre-drilled hole in the middle of the mounting plate, two arc-shaped positioning strips on both sides of the bottom of the mounting plate, anti-slip strips at the bottom of the positioning strips, the ends of the two positioning strips connected by a connecting plate, a first hydraulic cylinder fixed to the mounting plate with a telescopic rod, the first hydraulic cylinder controlling the positioning strips to bend and fit against the outer wall of the plastic pipe, thereby achieving positioning of the plastic pipe.

[0006] Preferably, a second hydraulic cylinder is connected to the rear of the fixing plate.

[0007] Preferably, multiple support columns are provided between the fixing plate and the mounting plate.

[0008] This utility model has a simple and ingenious structure and is easy to use. It can be positioned on the outside of plastic pipes of any diameter, thereby completing the drilling process of the plastic pipe. Attached Figure Description

[0012] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 3 It is known that a positioning structure for drilling holes in plastic pipes includes a fixing plate 1, a second hydraulic cylinder 8 connected to the rear of the fixing plate 1, the second hydraulic cylinder 8 can be fixed on some equipment to move and fix the device, an mounting plate 2 is connected to the bottom of the fixing plate 1, a drilling position 3 is reserved in the middle of the mounting plate 2, two arc-shaped positioning strips 4 are provided on both sides of the bottom of the mounting plate 2, and anti-slip strips 5 are provided at the bottom of the positioning strips 4. The ends of the two positioning strips 4 are connected by a connecting plate 6. A first hydraulic cylinder 7 with a telescopic rod fixed on the mounting plate 2 and fixed to the connecting plate 6 controls the positioning strips 4 to bend and fit against the outer wall of the plastic pipe to achieve positioning of the plastic pipe.

[0014] In practical use, this utility model

[0015] Install the drilling equipment at drilling position 3, place the plastic tube below the positioning strip 4, and bring the middle of the positioning strip 4 into contact with the plastic tube. The first hydraulic cylinder 7 extends, causing the connecting plate 6 to drive the end of the positioning strip 4 to bend and contact the plastic tube wall. The anti-slip strip 5 plays an anti-slip role, keeping the position of the positioning strip 4 and the plastic tube unchanged. At this time, the drilling equipment drills holes in the plastic tube, ensuring the accuracy of the drilling position 3 and the temperature.

[0016] In this device, the two first hydraulic cylinders 7 extend and retract synchronously, so that the two ends of the positioning strip 4 have the same curvature, which allows the punching device to be perpendicular to the plastic pipe wall, making the punching more accurate.

[0017] In this device, a connecting post is provided between the positioning strip 4 and the mounting plate 2. The connecting post connects to the middle part of the positioning strip 4, and both ends of the positioning strip 4 are connected to the connecting plate 6, so that when the positioning strip 4 is bent, the axis of the connecting post always passes through the axis of the plastic tube.

[0018] In this device, the positioning strip 4 is made of flexible and bendable sheet material, and the anti-slip strip 5 is made of flexible anti-slip material, such as rubber anti-slip strip 5, to improve the friction between the positioning strip 4 and the plastic tube and ensure positioning accuracy.

[0019] Multiple support columns 9 are provided between the fixing plate 1 and the mounting plate 2.

[0020] Compared with the prior art, this utility model has the following advantages: it can position plastic pipes of any diameter, and after positioning, it ensures that the hole is perpendicular to the pipe wall, thereby improving the accuracy and stability of drilling.
