Description

Technical Field

[0001] This utility model relates to a crossbeam for a laser cutting machine with movable calibration. Background Technology

[0002] Laser cutting equipment is widely used in machinery, construction and other fields. Different application areas have high requirements for the processing area, processing type and processing accuracy of laser cutting equipment, especially the improvement of processing accuracy is of paramount importance.

[0003] The most common bed structure in the current laser cutting industry is the gantry structure, which includes three main components: the bed beam and the module. Existing large-format laser cutting equipment typically has a long bed, generally between 10 and 30 meters, and often consists of spliced ​​beds. Therefore, suppliers often struggle to guarantee the parallelism tolerance of the guide rails on both sides during processing. Due to the excessive length of the bed, errors during processing are unavoidable, leading to deviations in the Y-axis parallelism of the beam movement from the drawing requirements. This affects the accuracy of laser-cut products, and in some cases, even prevents some products from meeting inspection standards. Summary of the Invention

[0004] The purpose of this invention is to provide a laser cutting machine crossbeam with movable calibration, which solves the problem of parallelism deviation in the Y-axis direction while ensuring the functionality of the original crossbeam, and avoids deviation in the parallelism of the Y-axis direction when the crossbeam moves.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a crossbeam body slidably mounted on a machine tool; the crossbeam body has a left end and a right end, the left end of the crossbeam body is slidably mounted on the machine tool via a first adjustment assembly, and the right end of the crossbeam body is slidably mounted on the machine tool via a second adjustment assembly; the first adjustment assembly includes a first sliding plate, a first sliding slider fixedly mounted on one side of the first sliding plate, a first adjustment slide rail fixedly mounted on the other side of the first sliding plate, and a first adjustment slider that can form a sliding fit with the first adjustment slide rail, wherein the first sliding slider is slidably mounted on the machine tool along the X-axis direction, and the first adjustment... The slide rail extends along the Y-axis. The first adjusting slider is fixedly mounted on the left end of the crossbeam body. The left end of the crossbeam body slides along the X-axis on the machine tool via the first sliding slider. The left end of the crossbeam body slides along the Y-axis on the machine tool via the sliding cooperation between the first adjusting slider and the first adjusting slide rail. The second adjusting assembly includes a second sliding plate and a second sliding slider fixedly mounted on one side of the second sliding plate. The second sliding slider slides along the X-axis on the machine tool. The right end of the crossbeam body is fixedly connected to the other side of the second sliding plate. The right end of the crossbeam body slides on the machine tool via the second sliding slider.

[0006] Furthermore, both sides of the first and second sliding sliders are provided with guide components. The guide components include extension blocks, rotating supports, connecting rods, guide wheels, and return springs. The extension blocks are fixedly mounted on both sides of the first and second sliding sliders. The rotating supports are fixedly mounted on the extension blocks and extend along the Y-axis. One end of the connecting rod has a through hole through which the rotating supports pass and form a rotating engagement with the rotating supports. Another end of the connecting rod has a rotating column extending along the Y-axis and forming a rotating engagement with the guide wheel. The connecting rod is rotatably mounted on the extension block through the through hole and the rotating engagement with the rotating supports. The rotating wheel is rotatably mounted on the connecting rod through the rotating engagement with the rotating column. Both sides of the first and second sliding sliders are fixed with return springs. One end of the return spring is fixedly mounted on the corresponding first or second sliding slider, and the other end acts on the corresponding connecting rod. The connecting rod rotates towards the corresponding first or second sliding slider due to the elastic force of the return spring and the rotating engagement with the rotating supports. The guide wheel moves towards the corresponding first or second sliding slider under the rotation of the connecting rod.

[0007] Furthermore, there are multiple first sliding sliders and multiple second sliding sliders. Each first sliding slider is evenly arranged on the first sliding plate along the X-axis direction, and each second sliding slider is evenly arranged on the second sliding plate along the X-axis direction. The guide wheel in the guide assembly on the first sliding slider is located between two adjacent first sliding sliders, and the guide wheel in the guide assembly on the second sliding slider is located between two adjacent second sliding sliders.

[0008] Furthermore, there are two first adjustment slide rails and two second adjustment slide rails, with the two first adjustment slide rails symmetrically arranged on the first sliding plate and the two second adjustment slide rails symmetrically arranged on the second sliding plate; there are three first adjustment sliders, with two of the three first adjustment sliders located on one first adjustment slide rail and the third first adjustment slider located on another first adjustment slide rail.

[0009] Furthermore, a rubber layer extending along the contour of the guide wheel is fixedly provided on the outer wall of the guide wheel, and multiple grooves are evenly arranged along the extension direction of the rubber layer on the rubber layer.

The first adjustment component includes a first sliding plate, a first sliding slider fixedly disposed on one side of the first sliding plate, a first adjustment slide rail fixedly disposed on the other side of the first sliding plate, and a first adjustment slider that can form a sliding fit with the first adjustment slide rail. By sliding the first sliding slider in the X direction on the machine tool and the first adjustment slider sliding in the Y direction on the first adjustment slide rail, the left end of the crossbeam and the right end of the crossbeam can be kept in the same parallelism when the crossbeam moves a long distance. Under the premise of ensuring the functionality of the original crossbeam, the problem of parallelism deviation in the Y direction is solved, and the deviation in parallelism in the Y direction when the crossbeam moves is avoided.

[0011] (2) The first and second sliding blocks of this utility model are provided with guide components on both side walls. The guide components include an extension block, a rotating support column, a connecting rod, a guide wheel and a return spring. The connecting rod rotates toward the corresponding first or second sliding block through the elastic force of the return spring and the rotational cooperation with the rotating support column. The guide wheel moves toward the corresponding first or second sliding block under the rotation of the connecting rod. The guide wheel can press against the slide rails that form a sliding cooperation between the first and second sliding blocks and the machine tool under the rotation of the connecting rod. When the guide wheel slides on the machine tool with the spliced ​​bed, the first or second sliding block can accurately form a sliding between the slide rails of two adjacent machine tools to ensure the stability of the crossbeam movement.

[0012] (3) The present invention has two first adjustment slide rails and two second adjustment slide rails. The two first adjustment slide rails are symmetrically arranged on the first sliding plate, and the two second adjustment slide rails are symmetrically arranged on the second sliding plate. The first adjustment slider has three parts. Two of the three first adjustment sliders are located on one first adjustment slide rail, and the third first adjustment slider is located on another first adjustment slide rail. The three points naturally determine a unique plane, which can perfectly adapt to the slight unevenness of the bottom surface of the workpiece, and ensure that the workpiece is in complete contact with all three support points, thereby achieving stable and repeatable positioning. It ensures that the crossbeam is in close contact with the first sliding plate and the second sliding plate.

[0013] (4) The outer wall of the guide wheel of this utility model is fixedly provided with a rubber layer extending along the contour direction of the guide wheel, and the rubber layer is provided with multiple grooves evenly arranged along the extension direction of the rubber layer; the rubber layer and the grooves can prevent slippage between the guide wheel and the slide rail when the guide wheel, the first sliding slider, the second sliding slider and the slide rail of the machine tool are pressed together, thus ensuring the stable use of the guide assembly.

[0018] Guide components 4 are provided on both side walls of the first sliding slider 22 and the second sliding slider 32. Each guide component 4 includes an extension block 41, a rotating support column 42, a connecting rod 43, a guide wheel 44, and a return spring 45. The extension block 41 is fixedly provided on both side walls of the first sliding slider 22 and the second sliding slider 32. The rotating support column 42 is fixedly mounted on the extension block 41 and extends along the Y-axis. One end of the connecting rod 43 has a through hole through which the rotating support column 42 passes and forms a rotatable engagement with it. Another end of the connecting rod 43 is fixedly provided with a rotating column extending along the Y-axis and forming a rotatable engagement with the guide wheel 44. The connecting rod 43 engages with the rotating support column 42 through the through hole.

The first sliding slider 22 and the second sliding slider 32 are both fixedly provided with the return spring 45 on their side walls. One end of the return spring 45 is fixedly mounted on the corresponding first sliding slider 22 or second sliding slider 32, and the other end of the return spring 45 acts on the corresponding connecting rod 43. The connecting rod 43 rotates towards the corresponding first sliding slider 22 or second sliding slider 32 through the elastic force of the return spring 45 and the rotational cooperation with the rotating column 42. The guide wheel 44 moves towards the corresponding first sliding slider 22 or second sliding slider 32 under the rotational action of the connecting rod 43.

[0019] The guide wheel 44, under the rotation of the connecting rod 43, can press against the slide rail that forms a sliding fit with the first sliding slider 22, the second sliding slider 32, and the machine tool.

[0020] Multiple first sliding sliders 22 and multiple second sliding sliders 32 are provided. Each first sliding slider 22 is evenly arranged on the first sliding plate 21 along the X-axis direction, and each second sliding slider 32 is evenly arranged on the second sliding plate 31 along the X-axis direction.

[0021] There are two first adjusting slide rails 23 and two second adjusting slide rails. The two first adjusting slide rails 23 are symmetrically arranged on the first sliding plate 21, and the two second adjusting slide rails are symmetrically arranged on the second sliding plate 31. There are three first adjusting sliders 24. Two of the three first adjusting sliders 24 are located on one first adjusting slide rail 23, and the third first adjusting slider 24 is located on another first adjusting slide rail 23. The three points naturally determine a unique plane, which can perfectly adapt to the slight unevenness of the bottom surface of the workpiece and ensure that the workpiece is in complete contact with all three support points, thereby achieving stable and repeatable positioning.

[0022] A rubber layer 441 is fixedly provided on the outer wall of the guide wheel 44, extending along the contour direction of the guide wheel 44. The rubber layer 441 has multiple grooves evenly arranged along the extension direction of the rubber layer 441.

[0023] The working principle of this utility model is as follows: the left end of the measuring body slides on the machine tool through the sliding of the first sliding slider 22 to form a sliding in the X-axis direction on the machine tool, and the left end of the crossbeam body 1 slides on the first sliding plate 21 through the sliding cooperation of the first adjusting slider 24 and the first adjusting slide rail 23 to form a sliding in the Y-axis direction. The right end of the measuring body slides along the machine tool via the second sliding slider 32, forming a sliding motion in the X-axis direction. With the right end of the crossbeam body 1 as the reference, when the left end of the measuring body slides along the machine tool in the X-axis direction, the left end of the crossbeam body 1 also slides in the Y-axis direction with the first sliding plate 21. This ensures that when the left end of the crossbeam body 1 moves in the X-axis direction, the left end of the crossbeam body 1 can slide and adjust in the Y-axis direction, ensuring that the left end of the crossbeam and the right end of the crossbeam are at the same parallelism. During the sliding process of the first sliding slider 22 and the second sliding slider 32, the guide wheel 44 in the guide assembly 4 presses against the slide rail on the machine tool. When the slide rail on the splicing machine tool slides, the guide wheel 44 always presses against the slide rail on the machine tool under the elastic force of the return spring 45, thereby guiding the first sliding slider 22 and the second sliding slider 32 to accurately form a sliding fit with the slide rail on the splicing machine tool.

[0024] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
