DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 The utility model provides a technical solution: an outer diameter detection device for seamless steel pipe manufacturing, comprising: a base 1 and a support frame 7, a fixed frame 2 is installed on the top of the base 1, a top frame 3 is installed between two groups of fixed frames 2, a cylinder 4 is installed at the bottom of the top frame 3, a movable plate 5 is installed at the bottom of the cylinder 4, a fixed wheel 6 is installed at the bottom of the movable plate 5, and the support frame 7 is installed between the two groups of fixed frames 2;

[0024] Support wheels 8 are provided on both sides of the support frame 7. A slider 9 is installed at the bottom of the support wheel 8 through the slide groove of the base 1. One side of the slider 9 is connected to a rotating shaft 10 through a protrusion. One side of the rotating shaft 10 is connected to a connecting rod 11. The side of the connecting rod 11 away from the rotating shaft 10 is connected to a rotating rod 12 through a rotating shaft. The end of the rotating rod 12 away from the connecting rod 11 is connected to a connecting shaft 13. The outer sleeve of the connecting shaft 13 is connected to a gear set 14. One side of the gear set 14 is connected to a driving motor 15. The support wheel 8 forms a sliding structure between the slider 9 and the slide groove of the base 1.

[0025] During specific implementation, the outer diameter detection equipment for seamless steel pipe manufacturing can place the seamless steel pipe on the support frame 7 when it is necessary to limit the seamless steel pipe, and then drive the gear set 14 to rotate through the driving motor 15. The gear set 14 is composed of two meshing gears, one of which is connected to the driving motor 15, and the other gear is meshed with it, so that the two sets of gears rotate in opposite directions, and drive the rotating rod 12 to rotate through the connecting shaft 13. The other end of the rotating rod 12 is connected to the connecting rod 11 through the rotating shaft, and the other end of the connecting rod 11 is connected between the rotating shafts 10 through the rotating shaft. When the rotating rod 12 rotates, it will pull the connecting rod 11 to rotate. The rotating shaft 10 is connected between the two sets of sliders 9 through the ear angle. At this time, the connecting rod 11 will pull the rotating shaft 10 while causing the two sets of sliders 9 to slide, thereby driving the top support wheel 8 to slide along the base 1. At this time, when the seamless steel pipe is placed on the support frame 7, the seamless steel pipe can be limited by the support wheel 8 to avoid the seamless steel pipe from being offset and affecting the detection effect.

[0026] See also Figure 1 , Figure 2 and Figure 3 It can be seen that when in use, the position between the two sets of support wheels 8 can be changed according to the use requirements, so as to play a role in limiting the seamless steel pipe.

[0027] A connecting frame 16 is installed at the bottom of the movable plate 5, a transmission motor 17 is installed on the top of the movable plate 5 through the outer shell, a turntable 18 is connected to the bottom of the transmission motor 17 through the output shaft, sliding blocks 19 are connected to both sides of the turntable 18 through arc grooves, a connecting rod 20 is connected to one side of the sliding block 19, a fixed rod 21 passing through the connecting frame 16 is installed on one side of the connecting rod 20, a marking pen 22 is installed on one side of the fixed rod 21, a ruler 23 is installed on one side of the marking pen 22, the ruler 23 is installed between the top frame 3 and the support frame 7, and two groups of rulers 23 are installed symmetrically about the center line of the top frame 3.

[0028] In specific implementation, the outer diameter detection device for seamless steel pipe manufacturing can make the cylinder 4 drive the movable plate 5 to move downward during the detection, so that the fixed wheel 6 contacts the seamless steel pipe, and then the transmission motor 17 can be started, so that the transmission motor 17 drives the turntable 18 at the bottom to rotate. When the turntable 18 rotates, the two sets of arc grooves running through the middle rotate, and then the sliding block 19 moves along the arc groove, so that the sliding block 19 drives the connecting rod 20 to move. Since the connecting rod 20 is an "L"-shaped structure and the connecting rod 20 The other end is connected to a fixed rod 21, and the connecting rod 20 will drive the fixed rod 21 to move, and the fixed rod 21 slides along the connecting frame 16, so that the fixed rod 21 can move more stably, and the fixed block will make the marking pen 22 move when it moves. The marking pen 22 is generally chalk, and the marking pen 22 will move along the ruler 23. When the marking pen 22 passes through the ruler 23, it will leave a mark on the ruler 23. By passing through the marking position, the outer diameter of the seamless steel pipe can be measured more accurately, which can reduce the error.

[0029] See also Figure 1 , Figure 4 and Figure 5 It can be seen that when in use, the marking pen 22 can be slid along the ruler 23, and then the marking position can be observed, so that the outer diameter of the seamless steel pipe can be measured more intuitively to avoid large errors.

[0030] To sum up: when using the outer diameter detection equipment for seamless steel pipe manufacturing, the entire outer diameter detection equipment can be placed in a stable position through the base 1, and then the seamless steel pipe can be placed on the support frame 7, and then the movable plate 5 is driven downward by the cylinder 4 at the bottom of the top frame 3. At the same time, the two sets of fixed frames 2 can make the cylinder 4 drive the movable plate 5 to move more stably. When the movable plate 5 drives the bottom fixed wheel 6 to move downward, the fixed wheel 6 contacts with the seamless steel pipe, and the outer diameter of the seamless steel pipe can be measured by observing the mark of the marking pen 22 on the ruler 23. This is the use feature of the outer diameter detection equipment for seamless steel pipe manufacturing.
