[0025] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples.

[0026] like Figures 1 to 6 As shown:

[0027] Embodiment 1: This embodiment provides a seamless steel pipe straightness detection device, including a positioning assembly 1, which includes a mounting base 101, a fixed chuck 102, an electric push rod 103, a lifting plate 104 and a connecting column 105. The fixed chuck 102 is rotatably connected to the side of the mounting base 101, and the electric push rod 103 is fixedly installed on the top of the mounting base 101. The lifting plate 104 is fixedly installed on the top of the electric push rod 103, and the connecting column 105 is plugged into the outside of the lifting plate 104; it also includes a detection assembly, which is composed of an indicating mechanism 2 and an adjustment mechanism 3;

[0028] The indicating mechanism 2 includes an indicating seat 201, a transmission cone wheel 202, an indicating cone wheel 203 and a detection probe 204. The indicating seat 201 is fixedly mounted on the side of the connecting column 105, and the transmission cone wheel 202 is rotatably connected to the inside of the indicating seat 201. The indicating cone wheel 203 is fixedly mounted on the inside of the indicating seat 201, and the detection probe 204 is plugged into the bottom of the indicating seat 201.

[0029] The adjustment mechanism 3 includes a holder 301, a positioning seat 302, an adjustment rod 303 and a friction transmission wheel 304. The holder 301 is inserted into the inside of the indicator seat 201, and the positioning seat 302 is inserted into the inside of the indicator seat 201. The adjustment rod 303 is rotatably connected to the inside of the indicator seat 201. The friction transmission wheel 304 is rotatably connected to the side of the holder 301, and the top and bottom of the friction transmission wheel 304 are frictionally transmitted with the indicator cone wheel 203 and the transmission cone wheel 202 respectively.

[0030] In the embodiment of the present disclosure, a pointer is provided on the side of the indicating cone wheel 203, and a scale is provided on the outer side of the indicating seat 201. The pointer indicates on the scale. During use, the positioning component 1 can realize the positioning of the seamless steel pipe, which is convenient for subsequent detection operations. The two fixed chucks 102 can realize the positioning of the two ends of the seamless steel pipe. When the electric push rod 103 drives the lifting plate 104 to move, the connecting column 105 can be lifted and lowered synchronously and the detection probe 204 can be pressed against the outside of the seamless steel pipe that has been positioned. Therefore, the straightness of the seamless steel pipe can be detected when the seamless steel pipe is rotated and the detection component is moved. The detection data can be indicated on the scale by the pointer, which is easy to use and fast to detect.

[0031] In the embodiment of the present disclosure, a reset spring 2041 is provided inside the detection probe 204, and the two ends of the reset spring 2041 respectively press against the inside of the detection probe 204 and the inside of the indicator seat 201. In use, under the action of the reset spring 2041, when the detection probe 204 is detecting, it will always press against the pipe wall of the seamless steel pipe. When the straightness of the seamless steel pipe changes, the detection probe 204 will also move up and down inside the indicator seat 201. The transmission cone wheel 202 and the top of the detection probe 204 are connected by a gear rack transmission. When the detection probe 204 moves, it can drive the transmission cone wheel 202 to rotate through the gear rack. When the transmission cone wheel 202 rotates, it can drive the indicator cone wheel 203 to rotate through the friction transmission wheel 304, so that the indicator cone wheel 203 can change the indicated position of the pointer on the scale when it rotates, thereby displaying the detection data, which is convenient for the detection personnel to observe and record and the subsequent steel pipe correction operation.

[0032] In the embodiment of the present disclosure, the outside of the rod body of the adjusting rod 303 is provided with a thread, and the adjusting rod 303 is screwed into the inside of the positioning seat 302 through the rod body thread. In use, the indication accuracy of the indicating mechanism 2 can be adjusted by the adjusting mechanism 3. When the adjusting rod 303 is rotated, the adjusting rod 303 can drive the positioning seat 302 to move horizontally inside the indicating seat 201 through the rod body thread. The interior of the positioning seat 302 is provided with a vertically arranged track groove 3021, and the side of the retaining frame 301 is provided with a track block 3011, and the track block 3011 is inserted into the interior of the track groove 3021. When the positioning seat 302 moves, the track groove 3021 can The track block 3011 can drive the retaining frame 301 to move along the oblique direction of the transmission cone wheel 202 and the indicator cone wheel 203, thereby changing the position of the friction transmission between the friction transmission wheel 304 and the transmission cone wheel 202 and the indicator cone wheel 203. Since the transmission cone wheel 202 and the indicator cone wheel 203 are conical wheel bodies, the change in the position of the friction transmission wheel 304 changes the transmission ratio obtained by the transmission cone wheel 202 and the indicator cone wheel 203 through the friction transmission wheel 304, thereby changing the rotation angle of the transmission cone wheel 202 when the detection probe 204 changes the unit distance, that is, the indication accuracy of the pointer, which is convenient to control and flexible to use.

[0033] The specific usage and function of this embodiment are as follows:

[0034] When the detection probe 204 is moved, the guide wheel 203 is rotated to move the guide wheel 204, and the guide wheel 203 is rotated to move the guide wheel 203. When the adjusting rod 303 is rotated, the adjusting rod 303 can drive the positioning seat 302 to move laterally inside the indicating seat 201 through the rod body thread. When the positioning seat 302 moves, the track groove 3021 can drive the retaining frame 301 to move along the oblique direction of the transmission cone wheel 202 and the indicating cone wheel 203 through the track block 3011, thereby changing the position of the friction transmission between the friction transmission wheel 304 and the transmission cone wheel 202 and the indicating cone wheel 203. Since the transmission cone wheel 202 and the indicating cone wheel 203 are conical wheel bodies, the change of the position of the friction transmission wheel 304 changes the transmission ratio obtained by the transmission cone wheel 202 and the indicating cone wheel 203 through the friction transmission wheel 304, thereby changing the rotation angle of the transmission cone wheel 202 when the detection probe 204 changes the unit distance, that is, the indicating accuracy of the pointer.
