The pre-buried pipes in the composite slab are cut according to the actual length requirements. The commonly used cutting method is that the cutting machine directly cuts the pipes, which lacks a positioning structure and needs to measure the size before cutting. The cutting efficiency is low, and the existing cutting equipment that can automatically adjust the cutting length still has some problems during use.

The utility model forms a positioning structure for building pipes by setting positioning rollers and cutting wheels, and the positioning structures installed on different frames are clamped independently.

[0004] Although the above-mentioned cutting equipment can realize automatic length adjustment before cutting, it lacks a positioning structure before pipe cutting, which affects the cutting accuracy and has low practicality. Therefore, the present application provides a cutting equipment for embedded pipes on assembled composite panels to meet the needs. Utility Model Content

[0024] Example 1: Reference Figure 1-4 The shown cutting equipment for embedded pipes on an assembled composite plate includes a mounting plate 1 and a first mounting seat 2 and a second mounting seat 3 mounted on the mounting plate 1, a pair of first positioning wheels 6 are rotatably connected to the first mounting seat 2 and the second mounting seat 3, and a positioning cutting unit 7 for positioning and cutting the pipe is provided on the first mounting seat 2 and the second mounting seat 3. The positioning and cutting unit 7 includes a rotating frame 8 rotatably connected to the first mounting seat 2 through a pin shaft, a first rotating shaft is rotatably connected to the rotating frame 8, a cutting wheel 9 is fixedly connected at the middle position of the first rotating shaft, a rotating sleeve 10 is rotatably connected to both sides of the first rotating shaft corresponding to the cutting wheel 9, a second positioning wheel 11 is fixedly connected to the rotating sleeve 10, and a cutting control unit for driving the cutting wheel 9 and the rotating sleeve 10 to rotate simultaneously is provided on the rotating frame 8.

[0025] When in use, the two ends of the pipe are placed at the positions of the first positioning wheels 6 on the first mounting seat 2 and the second mounting seat 3, and then the rotating frame 8 on the first mounting seat 2 is pushed to drive the second positioning wheel 11 to clamp and position one end of the pipe. The second positioning wheel 11 is a flexible non-slip rubber structure with a certain elasticity. It is deformable when squeezed and automatically recovers when the pressure is lost. At this time, the second positioning wheel 11 is squeezed and deformed to cooperate with the first positioning wheel 6 to clamp and position one end of the pipe, and then the position of the second mounting seat 3 is adjusted to achieve the purpose of adjusting the cutting length of the pipe. After the adjustment is completed, the rotating frame 8 on the first mounting seat 2 and the second mounting seat 3 is pushed to move at the same time, and the second motor 12 is started at the same time, so that the cutting wheel 9 and the second positioning wheel 11 are rotated to achieve simultaneous cutting of the two ends of the pipe, and during the cutting process and after the cutting is completed, the second positioning wheel 11 keeps squeezing the pipe, thereby ensuring that the pipe remains in a clamped state before and after cutting, thereby improving the cutting accuracy and having high practicality.

When the rotating frame 8 is no longer under force, the reset spring can drive the rotating frame 8 to automatically rotate and reset. Through the setting of the second screw 19 structure, the rotating frame 8 can be pushed to rotate, thereby driving the second positioning wheel 11 to move and extrude the pipe, thereby realizing the positioning of the pipe, which is convenient for the next step of length adjustment and cutting.

[0028] The first mounting seat 2 is fixedly connected to the mounting plate 1, and the second mounting seat 3 is slidably connected to the mounting plate 1.
