Description

Technical Field

[0001] The utility model relates to the technical field of machine tool accessories, in particular to a high-strength head crossbeam. Background Art

[0002] The head crossbeam usually refers to the horizontal structure in a machine tool for supporting and moving machine tool components (such as worktables, cutting tools, etc.). It is generally located above, on the side or at a specific position of the machine tool, depending on the design and functional requirements of the machine tool. The main function of the head crossbeam is to provide stable support and guidance to ensure that the machine tool components can maintain the correct position and posture during the machining process.

[0003] Reference can be made to an existing document, a crossbeam of a numerically controlled gantry machine tool (CN216657081U). The reference has a good fixed installation mechanism for the crossbeam body, making the installation and disassembly of the crossbeam of the numerically controlled gantry machine tool convenient.

[0004] At present, when the current head crossbeam is used on a numerically controlled machine tool, it is often connected to an automated moving component. The head crossbeam is installed above the moving component and moves linearly with the head crossbeam. At the same time, a processing component is usually installed at the front end of the head crossbeam. The processing component can adjust its position in front of the head crossbeam. The installation of the head crossbeam generally uses a bolt fixation method. When the connection is loose or the vibration is large during the displacement of the processing component, stress is concentrated on one side, which makes the head crossbeam prone to tipping during movement, affecting its service strength. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies in the prior art and propose a high-strength head crossbeam. The utility model can laterally support both ends of the gantry crossbeam main body through a diagonal support component to ensure the stability of the movement of the gantry crossbeam main body. And when the equipment on the gantry crossbeam main body is running, stress will be concentrated on one side. The hydraulic shock absorber inside the slider can buffer and dissipate the stress, further improving the service strength of the gantry crossbeam main body and effectively preventing tipping.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A high-strength head crossbeam, comprising: a gantry crossbeam main body, diagonal support components are installed on both the left and right sides of the gantry crossbeam main body.

[0011] The utility model is further configured such that equally spaced positioning holes two are provided on the surface of the fixed part of the adjusting rod, and the length of the adjusting rod can be fixed by connecting bolt two from the surface of the movable part of the adjusting rod into the corresponding positioning holes two.

[0012] The utility model is further configured to include: a slide rail, the slide rail is fixedly installed above the machine tool, the slider is located inside the slide rail, and the rubber block abuts against the inner side wall of the slide rail.

[0013] The utility model is further configured such that slots are provided at the front ends of the slide rails, and insertion plates are integrally connected to the rear sides of the slide rails.

[0027] Refer to Figures 1-4, A high-strength machine head crossbeam, comprising: a gantry crossbeam main body 1, with diagonal bracing components installed on both the left and right sides of the gantry crossbeam main body 1. The diagonal bracing components provide lateral support and protection for both sides of the gantry crossbeam main body 1, effectively preventing the gantry crossbeam main body 1 from tipping over during its displacement on the machine tool.

[0028] For reference, Figure 4 , In the diagonal bracing component: Two adjusting seats 3 are welded to both ends of the gantry crossbeam main body 1. An adjusting disc 15 is rotatably connected to the inner side of the adjusting seat 3. Below the adjusting disc 15 is connected to an adjusting rod 4, and the lower part of the adjusting rod 4 is further connected to the same adjusting disc 15 through a support rod 19. The adjusting disc 15 is arranged inside the same adjusting seat 3. The lower adjusting seat 3 is fixed to a slider 6, and the slider 6 is located in a slide rail 5 and slides in the slide rail 5 as the gantry crossbeam main body 1 moves.

[0029] Specifically, for reference, Figure 4 , On the surfaces of the adjusting disc 15 and the adjusting seat 3, positioning holes three 16 and positioning holes four 17 are respectively provided. The positioning holes three 16 and positioning holes four 17 are both annularly and equidistantly distributed. When the adjusting disc 15 is rotated, after the positioning holes three 16 and positioning holes four 17 are aligned, a bolt three 18 can be connected into the positioning holes three 16 and positioning holes four 17, and thus the angle adjustment of the adjusting disc 15 can be quickly completed.

[0030] Specifically, for reference, Figure 4 , The adjusting rod 4 adopts a two-section design. The fixed part is arranged in the inner groove of the movable part. The fixed part is integrally designed with the upper adjusting disc 15. A positioning hole two 13 is provided on the surface of the fixed part. The movable part is integrally designed with the lower adjusting disc 15. By pulling the movable part to a suitable position and then connecting a bolt two 14 to the corresponding positioning hole two 13, the length adjustment of the adjusting rod 4 can be quickly completed.

[0031] Furthermore, when installing this machine head crossbeam, first, the gantry crossbeam main body 1 is fixed above the moving component of the machine tool through two mounting plates 2 at the bottom of the gantry crossbeam main body 1. Then, according to the actual installation requirements, the angle and length of the diagonal bracing component are adjusted, and the slide rail 5 is installed above the machine tool. The slider 6 in the diagonal bracing component is inserted into the inside of the slide rail 5.

[0032] Moreover, during the installation process of the slide rail 5, its length can be spliced according to the actual usage requirements of the machine tool. Slots 9 and insertion plates 11 are respectively provided on the front and rear sides of the slide rail 5. Therefore, when adjacent slide rails 5 are installed, the insertion plate 11 can be inserted into the slot 9, and then four bolts one 10 are connected from the side of the slide rail 5 to fix the insertion plate 11 in the slot 9, thereby completing the assembly of the slide rail 5.

[0033] Furthermore, for reference, Figure 2, two sets of hydraulic buffers 7 are fixedly installed inside the slider 6. The piston rod of the hydraulic buffer 7 is connected to the rubber block 8. When the lateral stress of the main body 1 of the gantry beam is relatively large, buffer energy dissipation can be carried out through the rubber block 8 and the hydraulic buffer 7. The hydraulic buffer 7 dissipates energy through the internal hydraulic oil, playing a certain degree of protective role and improving the stability of the main body 1 of the gantry beam during movement.

[0034] Working principle: When using the present utility model, diagonal bracing components are installed on both the left and right sides of the main body 1 of the gantry beam. The diagonal bracing components provide lateral support and protection for both the left and right sides of the main body 1 of the gantry beam. When the main body 1 of the gantry beam is displaced on the machine tool, it can effectively prevent the main body 1 of the gantry beam from tipping over. When the lateral stress of the main body 1 of the gantry beam is relatively large, buffer energy dissipation can be carried out through the rubber block 8 and the hydraulic buffer 7. The hydraulic buffer 7 dissipates energy through the internal hydraulic oil, playing a certain degree of protective role and improving the stability of the main body 1 of the gantry beam during movement. Moreover, when installing the diagonal bracing components, the angle can be adjusted by rotating the adjusting disk 15, and the angle can be fixed by connecting the bolt three 18 to the positioning hole three 16 and the positioning hole four 17. The adjusting rod 4 can be adjusted in length, and the length can be fixed by pulling the movable part of the adjusting rod 4 and then connecting the bolt two 14 to the positioning hole two 13.

[0035] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
