DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figs. 1-3 As shown, this utility model provides an auxiliary positioning device for drilling steel pipes in construction, including a base plate 1, on which a mounting frame 2 is mounted, and also includes the following two main mechanisms: firstly, a positioning mechanism 3, which is mounted on the mounting frame 2 and is used to adjust the drilling position of the drilling mechanism; the mounting frame 2 is composed of two first support plates 21 and two second support plates 22, and a threaded rod 32 is rotatably connected to the top of the opposite side of the first support plate 21, and a crank 31 is installed at one end of the threaded rod 32, which can be rotated by turning the crank 31. A crossbar 33 is installed on the top of the opposite side of the second support plate 22. A movable plate 34 is threadedly connected to the threaded rod 32. The other end of the movable plate 34 is sleeved on the outer surface of the crossbar 33. When the threaded rod 32 rotates, the movable plate 34 will move linearly along the direction of the crossbar 33 and the threaded rod 32 due to the limiting effect of the crossbar 33, thereby realizing the adjustment of the position of the drilling mechanism. A mounting seat 35 is installed at the center of the upper surface of the movable plate 34. The mounting seat 35 is used to install the drilling mechanism. A positioning hole 36 is opened at the center of the upper surface of the movable plate 34. The positioning hole 36 can be used to more accurately determine the drilling position. A scale 38 is installed on the two second support plates 22. The scale 38 is provided with a scale bar. A triangular index 37 is installed at the end of the movable plate 34 away from the mounting seat 35. The axis of symmetry of the triangular index 37 coincides with one of the axes of symmetry of the positioning hole 36. By observing the scale on the ruler 38 corresponding to the triangular index 37, the position of the moving plate 34 can be determined intuitively, thereby precisely adjusting the drilling position of the drilling mechanism.

[0020] When the device is used, first of all, the base plate 1 is stably placed on the workbench, the device is ensured to be stable, the punching mechanism such as an electric drill is installed on the mounting seat 35, secondly, the steel pipe needing to be drilled is placed on the clamping seat 45, the steel pipe is located at the middle position of the arc-shaped clamping plate 48, and then the pneumatic cylinder 47 is started to make the pneumatic cylinder 47 contract, drive the two arc-shaped clamping plates 48 to close, and tightly clamp the steel pipe, at this time, the antiskid plate 46 and the antiskid block 49 are in close contact with the surface of the steel pipe, the friction is increased, the steel pipe is ensured to be stable, then the handle 31 is rotated to drive the threaded rod 32 to rotate, the moving plate 34 is moved along the cross rod 33, the scale on the scale 38 corresponding to the triangular index 37 is observed, the punching mechanism is moved to the position needing to be punched, the punching mechanism is started, and the steel pipe is drilled.
