[0026] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0027] Please refer to Figures 1-9 The utility model provides a kind of technical scheme: a high-precision plate shearing machine for bridge production, including plate shearing machine support one 1 and plate shearing machine support two 2, the bottom end of the left and right sides of plate shearing machine support one 1 is fixedly connected with the stand 3, the opposite side of the top of two stands 3 is fixedly connected with drive guide rail one 4 by being provided with recess, drive block one 5 is slidably connected in two drive guide rail one 4, the corresponding side of two drive block one 5 is respectively fixedly installed with the side of plate shearing machine support two 2;

[0028] The plate shearing machine support one 1 and the plate shearing machine support two 2 are provided with a stabilizing assembly 6, which is used to improve the stability of the plate shearing machine during use. The stabilizing assembly 6 comprises a hydraulic cylinder one 61, which is fixedly connected to the inner bottom wall of the groove on the plate shearing machine support one 1 and the plate shearing machine support two 2, respectively. The output end of the hydraulic cylinder one 61 is fixedly installed with a tool holder 62. The front and rear sides of the plate shearing machine support one 1 and the plate shearing machine support two 2 are fixedly installed with spring sleeves 63. One end of the spring rod 64 is fixedly installed on the inner wall of the spring sleeve 63. The other end of the spring rod 64 is fixedly connected with a clamping plate 612, which is slidingly connected in the spring sleeve 63. The opposite sides of the two clamping plates 612 are in contact with the tool holder 62.

[0029] The left and right sides of the plate shearing machine support one 1 and the plate shearing machine support two 2 are fixedly installed with a driving guide rail two 65. The driving block two 66 is slidingly connected in the two driving guide rails two 65. The front and rear sides of the opposite sides of the two driving blocks two 66 are fixedly connected with long plates 67. The opposite sides of the two long plates 67 are fixedly connected with hydraulic cylinders two 68. The output end of the two hydraulic cylinders two 68 is fixedly installed with a plug-in block 69. The left and right sides of the tool holder 62 are fixedly connected with extension plates 610. The front and rear sides of the extension plates 610 are provided with plug-in grooves 611. The extension plates 610 are located between the two plug-in blocks 69. The plug-in block 69 is plugged into the plug-in groove 611.

[0030] It should be noted that the stabilizing assembly 6 in the plate shearing machine support one 1 and the plate shearing machine support two 2 is composed of the same elements. The only difference is that the plate shearing machine support one 1 is placed with the groove opening direction upward, and the plate shearing machine support two 2 is placed with the groove opening direction downward, so that the cutting edges of the two tool holders 62 are oppositely placed and on the same vertical line. The clamping plate 612 and the contact end of the tool holder 62 are the friction end. When the tool holder 62 moves, it will rub with the clamping plate 612. Since the tool holder 62 moves upward when the hydraulic cylinder one 61 is ejected, it will vibrate. Since the two clamping plates 612 are tightly fitted when the tool holder 62 moves, when the tool holder 62 vibrates, it will be absorbed by the spring rod 64 and the clamping plate 612, thereby ensuring the stability of the tool holder 62 during movement. The spring torque on the spring rod 64 will be checked regularly, and the spring torque of the front and rear sides of the spring rod 64 is the same value.

[0031] The driving guide rail two 65 and the driving block two 66 move with the tool holder 62. The moving speed of the driving block two 66 is equal to the moving speed of the output end of the hydraulic cylinder one 61. The hydraulic cylinder two 68 drives the plug-in block 69 to plug into the plug-in groove 611 on the extension plate 610 on both sides of the tool holder 62, and stabilizes the installation of the tool holder 62. The installation method of the tool holder 62 and the hydraulic cylinder one 61 is mostly plug-in or clamped by buckle.

[0032] The upper surface of the plate shearing machine support one 1 is fixedly provided with a hydraulic cylinder three 7 on both sides, and the opposite side of the vertical support 3 is also fixedly provided with a hydraulic cylinder three 7.

[0033] The front and back sides of the plate shearing machine support two 2 are fixedly connected with a U-shaped frame 9, and the U-shaped frame 9 is fixedly provided with a servo motor 10, and the output end of the servo motor 10 is fixedly provided with one end of a transmission rod 11, and the other end of the transmission rod 11 extends inwardly and penetrates the bearing hole of the U-shaped frame 9, and is rotatably connected with the inner wall of the U-shaped frame 9, and the transmission rod 11 is fixedly connected with a positioning plate 12.

[0034] The upper and lower sides of the vertical support 3 are fixedly provided with a cover plate 13, and the two cover plates 13 are respectively in contact with the bottom side of the plate shearing machine support one 1 and the top side of the plate shearing machine support two 2.

[0035] Working principle: when the bridge production is used in the high-precision plate shearing machine, the operator places and moves the required cutting plate to the plate shearing machine support one 1 through the external conveying equipment, and when the plate to be processed moves to the required cutting position, the two hydraulic cylinders three 7 will drive the limiting plates 8 to clamp the two sides of the plate, and it should be noted that because the length of the cutting plate is different, an independent clamping device is provided in the external conveying equipment, which is used to limit the upper part of the cutting plate after the cutting plate is moved and positioned, and most of them use hydraulic cylinders to push the pressing plate to press the cutting plate, which is a prior art scheme and will not be described here. When the thickness of the bridge is relatively thick, the cutting plate will not deform when the two limiting plates 8 are extruded, and when the cutting plate is clamped, the driving guide rail one 4 drives the internal driving block one 5 to move downward, and the plate shearing machine support two 2 moves downward with the driving block one 5, at this time the servo motor 10 drives the transmission rod 11 to rotate, and the two positioning plates 12 are combined, and the gap between the two positioning plates 12 is the required cutting position, and it should be noted that when the cutting position is positioned, one end of the two positioning plates 12 is in contact, and the contact position is the determined cutting position, and when the cutting position is determined, the two positioning plates 12 will be slightly moved, so that a gap is formed between the two positioning plates 12, at this time the output end of the hydraulic cylinder one 61 drives the tool holder 62 to extend, the tool holder 62 in the plate shearing machine support two 2 moves downward, and the tool holder 62 in the plate shearing machine support one 1 moves upward, and the cutting plate is cut, the tool holder 62 in the plate shearing machine support two 2 is located between the two positioning plates 12, at this time the two positioning plates 12 are in contact with the surface of the cutting plate, so as to ensure the accuracy of the cutting position, and when the tool holder 62 extends, the clamping plate 612 is in contact with the surface of the tool holder 62 through the clamping force provided by the spring rod 64, so as to reduce the vibration of the tool holder 62 during movement.
