[0024] like Figure 1-2 As shown, a preferred embodiment of the utility model provides an internal expansion type beveling machine auxiliary device, comprising: a base 1, a gantry 2, a fixing clamp 3 and a height adjustment device 4;

[0025] The gantry 2 is vertically fixed on the base 1, and the height adjustment device 4 passes through the top of the gantry 2 and is movably connected to the gantry 2;

[0026] The closed end of the fixing clamp 3 is movably connected to the bottom of the height adjustment device 4, and the open ends on both sides of the fixing clamp 3 are movably connected to both sides of the gantry 2. This structure can ensure that the height adjustment device 4 and the fixing clamp 3 remain in a vertical state when lifting.

[0027] Furthermore, in the internal expansion beveling machine auxiliary device, the fixing clamp 3 is connected in sequence by a first vertical plate 9, a first side plate 10 inclined to the left, a horizontal plate 11, a second side plate 12 inclined to the right, and a second vertical plate 13, so that the whole is an arch structure. The design of the first side plate 10 and the second side plate 12 can effectively save some materials.

[0028] Furthermore, in the internal expansion type beveling machine auxiliary device, grooves 6 are provided inside both sides of the gantry 2, and the first vertical plate 9 and the second vertical plate 13 of the fixing clamp 3 are slidably fixed in the grooves 6 on both sides by screws. This structure can effectively enhance the overall stability.

[0029] Furthermore, in the auxiliary device of the internal expansion beveling machine, the height adjustment device 4 includes a hand crank 7 and a screw 8, the screw 8 passes through the top of the gantry 2 and is movably connected to the gantry 2 through a nut, one end of the screw 8 is connected to the hand crank 7, and the other end is movably connected to the horizontal plate 11 of the fixing clamp 3 through a nut. The height of the machine can be accurately adjusted by rotating the hand crank 7 and the inner thread of the nut.

[0030] Furthermore, in the internal expansion type beveling machine auxiliary device, a universal wheel 5 is provided under the base 1, and the universal wheel 5 can enable the entire device to move in all directions.

[0031] In this embodiment, a preferred implementation scheme also provides a method for using the internal expansion beveling machine auxiliary device, which is as follows:

[0032] The internal expansion beveling machine is installed in the auxiliary device through the fixing clamp 3. The movement of the auxiliary device relies on the universal wheel 5 under the base 1. When the user pushes the auxiliary device, the wheel moves forward, thereby driving the movement of the entire device. When the entire device moves to the end of the pipe to be processed, the beveling machine on the lower fixing clamp 3 is driven to rise by turning the hand crank 7. At the same time, the inner thread of the nut can also accurately adjust the height of the machine so that the beveling machine reaches a position that matches the pipe. Then move the auxiliary device and move the beveling machine's cutter head to the pipe end. Operate the control button at the back of the device to start processing.

[0033] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes.
