[0041] First, the bottom support fixing frame 6 of the present embodiment is provided with a base limiting slide rail 12, and the U-shaped support frame 1 is provided with two dovetail slide grooves 14. During operation, any dovetail slide groove 14 can be selected to cooperate with the bottom support fixing frame 6 according to the processing direction of the profile 11 to be expanded, and finally the assembly and fixation of the two are realized.

[0042] Preferably, the guide output mechanism of this embodiment includes:

[0043] Two base supports 5 are assembled and fixed inside the U-shaped support frame 1 by installing bolts, and an installation space is reserved between the two base supports 5;

[0044] A bottom support rotating rod 13 connected between the two base supports 5, the bottom support rotating rod 13 is rotatably connected to the base support 5; and

[0045] A rolling bearing 4 mounted on the upper surface of the base support 5;

[0046] At least one rolling bearing 4 is installed on each base support 5, and the space reserved between the two corresponding rolling bearings 4 on the two base supports 5 is a moving channel for the profile 11 to be expanded;

[0047] When the profile 11 to be expanded is expanded, the side surface of the profile 11 to be expanded is rollingly connected with the rolling bearing 4 on the corresponding side, and the bottom of the profile 11 to be expanded is rollingly connected with the bottom supporting rotary rod 13 .

[0049] The device of this embodiment installs the bottom support rotating rod 13 between the two base supports 5 to ensure that the bottom support rotating rod 13 can rotate freely, and the assembled base support 5 and the bottom support rotating rod 13 are fixed to the U-shaped support frame 1 by bolts through the mounting holes, and the four bearings at both ends are fixed to the base support 5 by the bearing fixing clamps 3 and the roller positioning pins 2, and the four rolling bearings 4 in the middle are fixed to the base support 5 by the roller positioning pins 2. In this way, a moving and clamping channel for the profile 11 to be expanded is formed.

[0050] Preferably, the tapered roller mechanism of this embodiment includes:

[0051] Rotate the rotating hand wheel 10 connected to the upper part of the U-shaped support frame 1, and the wheel rod of the rotating hand wheel 10 passes through the two side vertical plates of the U-shaped support frame 1; and

After confirming that the inspection device is operating well, the profile 11 to be expanded is opened upward, and the profile 11 to be expanded is introduced into the bottom of the tapered roller 8 through the cavity formed by the rolling bearings 4 on both sides of one end and the bearing fixing splint 3 and the bottom support rotary rod 13. The hand wheel 10 is rotated clockwise to drive the variable expansion tapered roller 8 to rotate clockwise. Due to the rolling friction between the profile 11 to be expanded and the tapered roller 8, the profile 11 to be expanded will move forward and complete the opening expansion. The rolling bearings 4 wheels installed on the left and right sides of the middle serve as the import and export wheels, and the bottom support rotary rod 13 can be rolled to guide and transmit the profile 11 to be expanded, and it is sent out from the cavity formed by the rolling bearings 4 on both sides of the other end and the bearing fixing splint 3 and the bottom support rotary rod 13.
