The telescopic measuring rod 105 is fixedly connected to the middle positioning plate 104 and is located on the side of the middle positioning plate 104 away from the end positioning plate 101. The sliding sleeve 106 is bolted to the telescopic measuring rod 105 and sleeved on the outside of the telescopic measuring rod 105. The hole positioning block 107 is bolted to the sliding sleeve 106 and is erected on the sliding sleeve 106.The end positioning plate 101 is T-shaped. A guiding sliding groove 1011 is provided at the wider upper end of the end positioning plate 101. The opening of the guiding sliding groove 1011 faces the direction of the middle positioning plate 104. The guiding sliding groove 1011 provides a sliding installation condition for the movable clamping assembly 103. Two clamping blocks 102 are slidably installed at the left and right ends of the end positioning plate 101 on the side close to the middle positioning plate 104 through the movable clamping assembly 103. The movable clamping assembly 103 is used to drive the two clamping blocks 102 to move synchronously and approach or move away from each other, so as to clamp I-beams of different sizes. The I-beam hole opening measurement and positioning device is clamped at one end of the I-beam, and the bottom of the middle positioning plate 104 abuts against the rib of the I-beam. Then the telescopic measuring rod 105 is located above the middle position of the rib of the I-beam. The telescopic measuring rod 105 can be telescopically adjusted, so that the sliding sleeve 106 sleeved on the telescopic measuring rod 105 is adjusted and moved above the I-beam. The sliding sleeve 106 is of a square frame structure. A threaded hole is provided at the middle position of the top of the sliding sleeve 106, which is used for a bolt to pass through the threaded hole to realize the fastening and positioning operation of the sliding sleeve 106 and the telescopic measuring rod 105. However, the hole positioning block 107 is also detachably connected by the same bolt. The hole positioning block 107 is of a U-shaped structure. A through hole matching the bolt is provided at the middle position of its top. Through holes are provided at both ends of the hole positioning block 107, which are used to fix the punching position. And the width of both ends of the hole positioning block 107 can be set according to the distance between the punching positions. Different hole positioning blocks 107 are set according to different requirements. Therefore, the end positioning plate 101 is close to the end of the I-beam, and the bottom of the middle positioning plate 104 is placed on the rib of the I-beam. Then the movable clamping assembly 103 is used to drive the two clamping blocks 102 to approach the outer sides of the two ends of the I-beam, so as to fixedly clamp the I-beam hole opening measurement and positioning device on the I-beam. Then the adapted hole positioning block 107 is fixed on the sliding sleeve 106 by bolts. The position of the hole positioning block 107 is adjusted by sliding the sliding sleeve 106 on the telescopic measuring rod 105, which is convenient for positioning punching, so as to realize the hole opening measurement and positioning of I-beams of different sizes within a certain range, and improve the applicability and universality of the device.

[0022] Among them, the slider 1031 is sleeved on the bidirectional screw 1032, threadedly connected to the bidirectional screw 1032, and extends into the guiding chute 1011; the bidirectional screw 1032 extends into the guiding chute 1011 and is rotatably connected to the end positioning plate 101 through a bearing; the driving member 1033 is installed on the end positioning plate 101, connected to the bidirectional screw 1032, and drives the bidirectional screw 1032 to rotate. The shape of the slider 1031 matches the shape of the guiding chute 1011, and the two sliders 1031 are provided with threaded holes matching the threads at both outer ends of the bidirectional screw 1032. Under the cooperation and limitation of the guiding chute 1011, when the bidirectional screw 1032 rotates, it drives the two sliders 1031 to move closer to or away from each other. Both ends of the bidirectional screw 1032 are connected to both ends of the end positioning plate 101 through bearings. The threads on the outer sides of both ends of the bidirectional screw 1032 are opposite, and the end of the bidirectional screw 1032 is connected with the driving member 1033. By driving the bidirectional screw 1032 to rotate clockwise or counterclockwise through the driving member 1033, the bidirectional screw 1032 drives the two sliders 1031 sleeved on the outside to move closer to or away from each other, thereby driving the clamping block 102 fixedly installed on the slider 1031 to move, so that the moving clamping assembly 103 drives the two clamping blocks 102 to clamp I-beams with different widths, realizing the clamping and positioning of the I-beam hole-opening measuring and positioning device.

Therefore, by rotating the fastening screw 10332 away from the end positioning plate 101, the turning handle 10331 can drive the bidirectional screw 1032 to rotate through manual rotation. When the two clamping blocks 102 are tightened against both sides of the I-beam, rotate the fastening screw 10332 to tighten against the end positioning plate 101, realize the rotation limit of the turning handle 10331, and realize the driving and fixing operation of the driving member 1033.

A threaded hole matching the bolt is provided on the upper side of one end of the measuring telescopic rod 1052 close to the measuring fixed rod 1051, which is used to realize the fixation with the measuring fixed rod 1051 through the threaded rotation of the bolt and facilitate the sliding adjustment of the measuring position. The measuring telescopic rod 1052 is slidably connected to the sliding sleeve 106. Through the measuring fixed rod 1051 and the measuring telescopic rod 1052, the telescopic measurement operation of the telescopic measuring rod 105 is realized, which is convenient for positioning the opening of I-beams with different lengths.

[0025] When using the I-beam hole-opening measurement and positioning device of the present utility model, the end positioning plate 101 is close to the end of the I-beam, and the bottom of the middle plate 104 is placed on the rib of the I-beam. Then, the two clamping blocks 102 are driven by the moving clamping assembly 103 to approach the outer sides of both ends of the I-beam, and the I-beam hole-opening measurement and positioning device is fixedly clamped on the I-beam. Then, the adapted hole positioning block 107 is fixed on the sliding sleeve 106 by bolts, and the position of the hole positioning block 107 is adjusted by sliding the sliding sleeve 106 on the telescopic measuring rod 105, which is convenient for positioning punching, realizes the hole-opening measurement and positioning of I-beams with different sizes within a certain range, and improves the applicability and universality of the device.

[0028] In this embodiment, the support rod 208 is fixedly connected to the measuring telescopic rod 1052 and is located at one end of the measuring telescopic rod 1052 away from the middle plate 104. The bottom of the support rod 208 and the bottom of the middle plate 104 are on the same horizontal line, and the width of the support rod 208 is the same as the width of the measuring telescopic rod 1052. By installing the support rod 208 on the measuring telescopic rod 1052, the installation and support effect of the telescopic measuring rod 105 is better, and it is avoided that the longer telescopic measuring rod 105 is deformed and bent, resulting in inaccurate measurement.
