When the laser receiver is moved along the ring, the receiving end needs to be opposite to the laser transmitter at all times. When the error is large, the measurement cannot be performed. There are many positioning points that need to be detected along the ring on the flange. The operator needs to pay attention to the relative situation every time the laser receiver is moved, which affects the detection efficiency.

[0033] The present application will be further described in detail below in combination with the drawings and specific embodiments.

In this text, “one” not only means “only one”, but also means “more than one”, and “several” includes “two” and “more than two”.

[0035] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0036] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0037] like Figures 1-7 As shown, a flange precision detection platform includes a laser emitter 101 and a laser receiver 102, including: a movable seat 3, which is arranged on the flange along a circular movement; a slider 4, which is slidingly arranged on the movable seat 3, and the slider 4 slides close to or away from the axis of the flange; a rotating frame 5, which is rotatably arranged on the slider 4; a clamping seat 6, which is arranged on the rotating frame 5 and rotates with the rotating frame 5, and the clamping seat 6 is clamped and sleeved on the laser receiver 102; a mounting seat 7, which is rotatably arranged on the upper end of the laser emitter 101; a wire reel 8, which is arranged on the mounting seat 7, and a pull wire 801 is wound on the wire reel 8, and the end of the pull wire 801 is connected to the rotating frame 5, and the wire reel 8 provides tension to the rotating frame 5 through the pull wire 801, so as to make the receiving end 1021 of the laser receiver 102 opposite to the laser emitter 101.

[0038] During use, assuming the flange is positioned horizontally, laser emitter 101 is fixed to the flange end face. Mounting base 7 rotates above laser emitter 101, and cable reel 8 follows the rotation of mounting base 7. Moving base 3 moves in a circular motion on the flange, and slider 4 slides on moving base 3 to adjust the radial position of laser receiver 102 on the flange. Before testing, multiple point detections can be performed.

[0039] When detecting, the laser receiver 102 is fixed on a detection point of the flange, and the receiving end 1021 is opposite to the laser emitter 101, so that the detection of the point is completed. When changing the detection point, the moving seat 3 moves on the flange, away from or close to the laser emitter 101. Taking the case of moving away as an example, the laser receiver 102 moves away from the laser emitter 101, and when reaching the detection point, the pull line 801 is in a tension state, providing a pulling force to the rotating frame 5. Then, the pull line 801 is the shortest straight line between the winding device 8 and the rotating frame 5, so that one side of the rotating frame 5 is opposite to the winding device 8. The laser receiver 102 is installed on the clamping seat 6 below the rotating frame 5, and the receiving end 1021 of the laser receiver 102 is opposite to the pull line 801, so that the receiving end 1021 is automatically opposite to the laser emitter 101. When the sliding block 4 adjusts the radial position, the receiving end 1021 and the laser emitter 101 are automatically opposite in the same way.

[0040] The winding device 8 can adopt the following prior art. For example, the winding device 8 is automatically retracted and tensioned by elasticity (such as a telescopic tape measure structure), and the pull line 801 is pulled out from the outlet of the winding device 8 and fixedly connected to the rotating frame 5. When the rotating frame 5 moves on the flange under the action of the pulling force, one side of the rotating frame 5 is kept opposite to the winding device 8 automatically. The winding device 8 can also use winch technology to control the recovery and tension of the pull line 801 by a motor. When the laser receiver 102 moves, the winding device 8 tightens the pull line 801 to provide a pulling force to the rotating frame 5. Of course, the winding device 8 can also manually wind the pull line 801 to provide a pulling force.

[0041] The end of the pull line 801 can be connected to the middle of the rotating frame 5, or divided into two equal lines and connected to the two sides of the rotating frame 5 respectively.

[0042] The movement of the moving seat 3 and the sliding of the sliding block 4 can be manually operated by workers. The laser receiver 102 is a product in the prior art. When the laser receiver 102 is fixed by magnetic attraction, the switch of the magnetic attraction can be manually controlled by workers. Of course, it can be understood that, according to the prior art, the moving seat 3 and the sliding block 4 can be driven by electric control equipment to realize automatic movement and change the detection point. The laser receiver 102 can adopt or modify the magnetic attraction convenient for electric control, or drive the switch of the magnetic attraction by a motor to realize automatic flatness detection.

[0043] Further, the device further comprises a plurality of pulleys 301, which are rotatably arranged on the moving seat 3 and used to roll against the inner or outer ring surface of the flange. Two of the pulleys 301 roll against the outer ring surface of the flange, and one of the pulleys 301 rolls against the inner ring surface of the flange.

[0044] In use, three pulleys 301 can be arranged on the moving seat 3, two of which are located on the outer ring of the flange, and one is located on the inner ring of the flange, which can be relatively stable along the annular flange, and the pulley 301 can reduce the friction on the flange, and the roller can be arranged below the moving seat 3 and roll against the end surface of the flange to reduce friction and wear.

[0045] Further, the rotating frame 5 has a connecting column 501 at the upper part and a guide rod 502 at the lower part, and the end of the pull wire 801 is fixedly connected with the connecting column 501; the clamping seat 6 is arranged on the rotating frame 5 in a lifting manner, the clamping seat 6 has a vertical slide 601, and the guide rod 502 is slidingly arranged in the slide 601. One end of the sliding block 4 has an extension plate 401, the connecting column 501 is rotatably arranged on the extension plate 401, and the laser receiver 102 is located below the connecting column 501.

[0046] In use, the connecting column 501 at the upper part of the rotating frame 5 is located above the extension plate 401, a through hole can be formed in the extension plate 401, the connecting column 501 rotates in the through hole, and the guide rod 502 at the lower part of the rotating frame 5 is slidingly arranged in the slide 601 on the clamping seat 6. In the case that the clamping seat 6 tightly holds or clamps the laser receiver 102, the laser receiver 102 can be conveniently adjusted after being moved upward, and the abrasion of the laser receiver 102 on the end surface of the flange can be reduced. The slide 601 and the guide rod 502 are structurally matched, the guide rod 502 can be a quadrangular prism, so that the clamping seat 6 can be lifted and rotated with the rotating frame 5.

[0047] Further, the rotating frame 5 slides in the radial direction of the flange.

[0048] In use, when the sliding block 4 slides, the rotating frame 5 moves, and the movement path of the sliding block 4 can be calibrated according to the movement track of the rotating frame 5. The rotating frame 5 moves in the radial direction, so that the detection points of multiple turns can be better set in the radial direction, and the floating of the end surface of the flange in the radial direction can be better displayed through the multiple detection points in the radial direction.

[0049] Further, the device further comprises a lead screw 9 rotatably arranged on the moving seat 3, the sliding block 4 is threadedly connected with the lead screw 9, and the lead screw 9 is used to drive the sliding block 4 to reciprocatingly slide; and a driving motor 901 is used to drive the lead screw 9 to rotate.

[0050] In use, the sliding block 4 is driven by the lead screw 9 to change the detection position in the radial direction, so that the detection points of multiple turns can be more accurately set, and manual adjustment is reduced.

[0051] The mobile seat 3 can be provided with a support, the sliding block 4 slides on the support, the driving motor 901 is installed on the support and is supported by a small-diameter column in a hollow shape, the receiving end 1021 of the laser receiver 102 is opposite to the hollow position to reduce the shielding of the receiving end 1021.

In addition, the features and embodiments can be modified to adapt to specific conditions and materials under the guidance of the present application without departing from the spirit and scope of the present application.
