Abstract
Description
Technical Field
[0001] This utility model relates to the field of automation equipment, and in particular to a double-sided, double-rail, smooth sliding gantry structure for a machining center. Background Technology
[0002] Machining is the foundation of the machinery industry; with the continuous advancement of technology, gantry machining centers have been widely used in machining.
[0003] The gantry frame of a gantry machining center is often large in size and heavy in weight, so it requires a large driving force when working. The profiles used in this gantry machining center are also large profile products, which are also characterized by large size and heavy weight.
[0004] When traditional gantry machining centers process profiles, linear guides need to be installed inside the gantry bed. However, the height of the linear guides is almost the same as the processing surface of the profile, which causes some debris to fall onto the linear guides during profile processing, affecting the movement of the processing equipment sliding on the linear guides. Utility Model Content
[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a double-sided, double-rail, smooth sliding gantry structure for a machining center, which solves the problem that some debris falls onto the linear rails during profile processing, affecting the movement of the machining equipment sliding on the linear rails.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a double-sided, double-rail, smooth sliding gantry structure for a machining center, comprising a gantry bed and a frame slidably mounted on the gantry bed. The gantry bed is provided with two mounting platforms protruding from the machining surface, and guide rails are provided at the upper ends of the two mounting platforms. The frame slides on the guide rails via a drive assembly, and a baffle is provided at the lower part of the side of the frame adjacent to the machining surface to block the guide rails. A movable machining head is provided on the frame, and the machining head is located in front of the baffle.
[0007] Furthermore, there are no fewer than two guide rails on the installation platform, and the two guide rails are divided into a first guide rail near the side wall of the gantry bed and a second guide rail near the center of the machining surface, with a baffle covering the side wall of the second guide rail.
[0008] Furthermore, the drive assembly includes a rack disposed between the first linear guide and the second linear guide, and a drive member that engages with the rack.
[0009] Furthermore, the teeth of the rack face the first linear guide, and the rack contains multiple segments.
[0010] Furthermore, sliders are slidably connected to both the first and second linear rails, and the sliders are connected to the frame.
[0011] Furthermore, the first and second linear rails are recessed on both sides with slots, and the slider is provided with a block that is inserted into the slot.
[0012] Furthermore, a first gap is provided between the opposite sidewalls of the baffle and the slider.
[0013] Furthermore, a second gap is provided between the lower end face of the slider and the processing table surface of the mounting platform.
[0014] Furthermore, the driving component includes a driving cylinder and a gear disposed on the output shaft of the driving cylinder, the gear meshing with a rack.
[0015] Furthermore, the drive cylinder is connected to the frame via a mounting bracket, and the mounting bracket is slidably connected to the slider.
[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, the guide rail applied in the gantry machining center is installed on the mounting platform, and the mounting platform is higher than the machining surface of the gantry bed, so that the debris generated by the workpiece placed on the machining surface during machining is not easily splashed onto the guide rail. In addition, the side edge of the guide rail near the middle of the machining surface is blocked by the baffle to prevent the debris splashed during workpiece machining from entering the frame or the drive assembly, so as to ensure the stability of the frame when moving on the guide rail.
[0017] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0031] Please refer to Figure 1-6 As shown, this invention illustrates the specific structure of a preferred first embodiment of a machining center, which is a double-sided, double-rail, smoothly sliding gantry structure. It includes a gantry bed 10 and a frame 20 slidably mounted on the gantry bed 10. The gantry bed 10 has two mounting platforms 30 protruding from the machining surface 11, with guide rails 40 at their upper ends. The frame 20 slides on the guide rails 40 via a drive assembly 50. A baffle 21 is provided on the lower part of the frame 20 near the machining surface 11 to block the guide rails 40. A movable machining head 22 is mounted on the frame 20, located in front of the baffle 21. This design improves upon existing gantry machining centers where the linear guides for moving the gantry are nearly parallel to the workpiece, causing debris to easily fall onto the linear guides during machining and hindering gantry movement. The guide rail 40 used in this gantry machining center is mounted on the mounting platform 30, which is higher than the machining surface 11 of the gantry bed 10. This prevents debris generated during machining of the workpiece placed on the machining surface 11 from splashing onto the guide rail 40. In addition, the side edge of the guide rail 40 near the center of the machining surface 11 is blocked by the baffle 21 to prevent debris splashed during workpiece machining from entering the frame 20 or the drive assembly 50, thus ensuring the stability of the frame 20 when moving on the guide rail 40.
[0032] like Figure 1 As shown, for example, a mounting platform 30 has at least two guide rails 40, and the two guide rails 40 are divided into a first guide rail 41 near the side wall of the gantry bed 10 and a second guide rail 42 near the center of the machining surface 11. A baffle 21 covers the side wall of the second guide rail 42. The design of two guide rails 40 on the mounting platform 30 can enhance the stability of the gantry bed 10 during sliding. In addition, the baffle 21 is located next to the second guide rail 42, and the second guide rail 42 is near the center of the machining surface 11.
[0033] It should be noted that the frame 20 is equipped with a movable machining head 22, and the baffle 21 is located behind the machining end of the machining head 22, so that the debris generated by the machining head 22 when machining the workpiece will not splash onto the subsequent movement trajectory of the frame 20, thereby ensuring that the sliding of the frame 20 on the guide rail 40 remains stable and enhancing the machining accuracy of the machining head 22.
[0034] like Figure 2 As shown, exemplarily, the drive assembly 50 includes a rack 51 disposed between the first linear guide 41 and the second linear guide 42, and a drive member 52 that meshes with the rack 51. Due to the meshing of the drive member 52 and the rack 51, when the drive member 52 is running, it can drive the frame 20 to slide along the guide rail 40 by meshing and pressing with the rack 51.
[0035] It should be noted that the movement of the frame 20 is driven by the meshing of the drive component 52 and the rack 51. The drive component 52 is mounted on the frame 20, which makes the frame 20 suitable for gantry beds 10 of different lengths, thus increasing the adaptability of the gantry structure.
[0036] like Figure 5 As shown, for example, the teeth of the rack 51 face the first linear guide 41, and the rack 51 contains multiple segments. Because the teeth face the first linear guide 41, and the first linear guide 41 is located next to the side wall of the gantry bed 10, the debris splashed when the machining head 22 processes the workpiece will not splash onto the meshing end of the rack 51, thereby improving the stability of the frame 20 during operation.
[0037] like Figure 5 As shown, for example, sliders 43 are slidably connected to both the first rail 41 and the second rail 42, and the sliders 43 are connected to the frame 20. By connecting the sliders 43, which slide on the first rail 41 and the second rail 42, to the frame 20, the frame 20 can be limited and the stability of the frame 20 during sliding can be improved.
[0038] Specifically, the first linear guide 41 and the second linear guide 42 are recessed on both sides with slots 44, and the slider 43 is provided with a locking block 45 that inserts into the slot 44. By locking the locking block 45 and the slot 44, the frame 20 can be prevented from shifting due to the meshing of the drive member 52 and the rack 51.
[0039] like Figure 3 As shown, for example, a first gap 1 is provided between the opposite sidewalls of the baffle 21 and the slider 43. Because the baffle 21 and the slider 43 are provided with the first gap 1, the baffle 21 can block the debris that splashes during processing from falling onto the subsequent sliding path of the frame 20, while also preventing the friction between the baffle 21 and the slider 43 from affecting the smoothness of the sliding of the frame 20.
[0040] like Figure 5As shown, for example, a second gap 2 is provided between the lower end face of the slider 43 and the processing table surface of the mounting platform 30. By setting the second gap 2 between the slider 43 and the processing table surface of the mounting platform 30, even if the debris splashed during workpiece processing falls onto the processing table surface, the second gap 2 will prevent the slider 43 from rubbing against the processing table surface due to the debris, thus reducing the stability of the frame 20 during sliding.
[0041] The drive unit 52 includes a drive cylinder 521 and a gear 522 disposed on the output shaft of the drive cylinder 521, the gear 522 meshing with the rack 51.
[0042] The drive cylinder 521 is connected to the frame 20 via the mounting bracket 3, and the mounting bracket 3 is slidably connected to the slider 43.
[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
