Description

Technical Field

[0001] This utility model relates to the field of gantry structure technology, specifically a quick clamping device for workpieces in a gantry structure. Background Technology

[0002] In modern industrial manufacturing, the industry is moving towards high precision, high efficiency, and large-scale production. Gantry-type equipment, with its unique structural advantages, plays an indispensable role in many fields. For example, in the machining industry, gantry milling machines, gantry planers, and gantry machining centers can perform various machining operations such as milling, planing, and boring on large workpieces, meeting the high-precision machining needs of large parts in aerospace, shipbuilding, and automotive manufacturing industries.

[0003] However, for workpiece clamping on gantry structure equipment, most of the clamping methods are manual. For example, the workpiece is fixed on the worktable by using bolts, nuts and pressure plates. The operator needs to manually tighten multiple bolts to adjust the clamping force applied by the pressure plate to the workpiece so that the workpiece is placed stably. Each time the workpiece is clamped, a lot of time is spent tightening the bolts one by one. In the case of mass production, the frequent clamping operations cause the equipment to be in standby mode for a long time, which seriously reduces the overall production efficiency. Moreover, when disassembling the workpiece, a lot of time is also spent loosening each bolt. The entire clamping and disassembly process is cumbersome and labor-intensive.

[0004] In view of this, we propose a gantry structure for quick workpiece clamping. Summary of the Invention

[0005] The purpose of this utility model is to provide a quick clamping device for workpieces in a gantry structure. This quick clamping device for workpieces in a gantry structure solves the problem that most workpiece clamping on gantry structure equipment is done manually, which seriously reduces the overall production efficiency during mass production.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A workpiece quick clamping device with a gantry structure includes a gantry frame, a slide saddle slidably connected to the surface of the gantry frame, a hydraulic rod fixedly installed at the bottom of the slide saddle, a slider fixedly installed on the surface of the hydraulic rod, and the slider slidably connected to the surface of the slide saddle.

[0008] It also includes clamping components for quick clamping of workpieces;

[0011] Preferably, a connecting strip is fixedly installed on the surface of the slider, a telescopic rod is fixedly installed inside the connecting strip, a fixing spring is fixedly installed on the surface of the telescopic rod, and a positioning block is fixedly installed at the bottom of the telescopic rod.

[0012] Preferably, a limiting block is slidably connected to the top of the fixed strip, and the limiting block is fixedly installed on the top of the movable block.

[0013] Preferably, the movable component includes: a fixed plate, which is rotatably connected to the inner side of the connecting frame; the surface of the fixed plate is connected to the surface of the movable rod via a belt drive; a sliding plate is slidably connected to the surface of the fixed plate; a connecting spring is installed inside the sliding plate; the connecting spring is fixedly installed on the outer wall of the fixed plate; and a support plate is fixedly installed on the outer side of the sliding plate.

[0014] Preferably, the top of the fixed plate is hinged with an insert plate, a spiral spring is fixedly installed on the outside of the insert plate, the spiral spring is fixedly installed on the top of the fixed plate, an insert block is fixedly installed on the bottom of the insert plate, a toothed plate is fixedly installed on the top of the slide plate, and the insert block is inserted into the inner side of the toothed plate.

[0015] Preferably, the top of the fixing strip has a groove, the top of the limiting block has a recess, and the cross-section of the tray is triangular.

[0016] Preferably, the active components are provided in two sets, and both sets of active components are symmetrically arranged about the center line of the slider as the axis of symmetry.

[0017] By employing the above technical solution, this utility model provides a workpiece quick clamping device for a gantry structure. It possesses at least the following beneficial effects:

[0018] (1) By setting up the clamping component, the present invention drives the sliding block and connecting plate to slide upward by activating the telescopic cylinder and pulls the movable block to move closer to the center point of the fixed strip on the surface of the fixed strip. When the movable block moves, it will drive the bottom connecting frame and clamping block to slide in the same direction as the movable block. When the clamping block slides, it will quickly clamp the workpiece, preventing the use of traditional and cumbersome clamping methods, greatly saving the workpiece clamping time and improving production efficiency.

When the pallet swings downward, it will move to the bottom of the workpiece. The length of the sliding plate is adjusted on the surface of the fixed plate. After the adjustment is completed, it will be reset under the action of the connecting spring, so that the pallet fits against the bottom of the workpiece to restrict it and prevent the bottom of the workpiece from being suspended. For some workpieces with large size and heavy weight, the workpiece may be deformed under the long-term action of its own weight if it is only fixed by the clamping force of the surrounding area. This improves the protection of the workpiece and enhances the stability of the workpiece transportation. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] A gantry structure workpiece quick clamping device, such as Figures 1-3 As shown, it includes a gantry frame 1, a sliding saddle 2 slidably connected to the surface of the gantry frame 1, a hydraulic rod 3 fixedly installed at the bottom of the sliding saddle 2, a slider 4 fixedly installed on the surface of the hydraulic rod 3, and the slider 4 slidably connected to the surface of the sliding saddle 2.

[0031] It also includes a clamping assembly 5 for quick clamping of the workpiece;

[0032] Movable component 6 is used to lift the bottom of the clamped workpiece;

[0033] First, the clamping assembly 5 includes: a telescopic cylinder 51, which is fixedly installed on the top of the slider 4. A sliding block 52 is fixedly installed on the surface of the telescopic cylinder 51. A connecting plate 53 is fixedly installed on the surface of the sliding block 52. One end of a movable rod 54 is hinged to the inner side of the connecting plate 53. A movable block 55 is hinged to the other end of the movable rod 54. A fixing strip 56 is fixedly installed on the surface of the slider 4. The movable block 55 is slidably connected to the surface of the fixing strip 56. A connecting frame 57 is fixedly installed at the bottom of the movable block 55. A clamping block 58 is fixedly installed on the inner side of the connecting frame 57. The sliding of the sliding block 52 and the connecting plate 53 can be controlled by the telescopic cylinder 51 to move the movable rod 54 and the clamping block 58 at the bottom toward the surface of the workpiece.

[0034] Secondly, a connecting strip 59 is fixedly installed on the surface of the slider 4, and a telescopic rod 510 is fixedly installed inside the connecting strip 59. A fixing spring 511 is fixedly installed on the surface of the telescopic rod 510, and a positioning block 512 is fixedly installed at the bottom of the telescopic rod 510. The fixing spring 511 on the surface of the telescopic rod 510 can be used to achieve the effect of resetting the telescopic rod 510 after use.

[0035] Furthermore, a limiting block 513 is slidably connected to the top of the fixed strip 56. The limiting block 513 is fixedly installed on the top of the movable block 55. The upward swing of the abutment positioning block 512 can be achieved by sliding the limiting block 513.

[0036] In this embodiment, by setting up the clamping component 5, the telescopic cylinder 51 is activated to drive the sliding block 52 and the connecting plate 53 to slide upward and pull the movable block 55 to move closer to the center point of the fixed strip 56 on the surface of the fixed strip 56. When the movable block 55 moves, it will drive the connecting frame 57 and the clamping block 58 at the bottom to slide in the same direction as the movable block 55. When the clamping block 58 slides, it will quickly clamp the workpiece, preventing the use of traditional and cumbersome clamping methods, greatly saving the workpiece clamping time and improving production efficiency.

[0037] Example 2

[0038] like Figures 4-6 As shown, the movable component 6 includes: a fixed plate 61, which is rotatably connected to the inner side of the connecting frame 57. The surface of the fixed plate 61 is connected to the surface of the movable rod 54 via a belt drive. A sliding plate 63 is slidably connected to the surface of the fixed plate 61. A connecting spring 64 is installed inside the sliding plate 63. The connecting spring 64 is fixedly installed on the outer wall of the fixed plate 61. A support plate 65 is fixedly installed on the outer side of the sliding plate 63.

[0039] Furthermore, a plug plate 66 is hinged to the top of the fixed plate 61, and a spiral spring 67 is fixedly installed on the outside of the plug plate 66. The spiral spring 67 is fixedly installed on the top of the fixed plate 61, and a plug block 68 is fixedly installed on the bottom of the plug plate 66. A toothed plate 69 is fixedly installed on the top of the slide plate 63, and the plug block 68 is inserted into the inside of the toothed plate 69. The spiral spring 67 provided on the surface of the plug plate 66 can achieve the effect of resetting after the plug plate 66 moves.

[0040] Finally, a groove 560 is provided at the top of the fixing strip 56, which allows the sliding block 55 to slide along the limiting block 513 when it slides. A groove 5130 is provided at the top of the limiting block 513, which allows the positioning block 512 to be inserted into the limiting block 513 for fixation. The cross-section of the support plate 65 is triangular, which allows different sized workpieces to resist the support plate 65. Two sets of movable components 6 are provided, and both sets of movable components 6 are symmetrically arranged with the center line of the slider 4 as the axis of symmetry. The balance of the movable component 6 in lifting the workpiece can be achieved by the two sets of movable components 6.

[0041] In this embodiment, through the setting of the movable component 6, when the movable rod 54 slides, it will also drive the fixed plate 61, the sliding plate 63 and the support plate 65 to swing downwards via the belt. When the support plate 65 swings downwards, it will move to the bottom of the workpiece. The sliding plate 63 is used to adjust the length on the surface of the fixed plate 61. After the adjustment is completed, it will be reset under the action of the connecting spring 64, so that the support plate 65 fits against the bottom of the workpiece to restrict it and prevent the bottom of the workpiece from being suspended. For some large and heavy workpieces, if there is no effective support at the bottom and they are only fixed by the clamping force of the surrounding area, the workpiece may deform under the long-term action of its own weight, which will destroy its original shape and dimensional accuracy. This improves the protection of the workpiece and enhances the stability of workpiece transportation.

[0042] In use, the workpiece quick clamping device of this utility model with a gantry structure can be adjusted by sliding the slide saddle 2 left and right on the surface of the gantry frame 1. Activating the hydraulic rod 3 drives the slider 4 to slide downwards on the surface of the slide saddle 2. When the slider 4 slides downwards, it drives the clamping assembly 5 to slide downwards. When clamping the workpiece, activating the telescopic cylinder 51 drives the sliding block 52 to slide upwards on the surface of the slider 4. When the sliding block 52 slides upwards, it drives the connecting plate 53 to slide upwards. When the connecting plate 53 slides upwards, it drives the movable rod 54 to pull the movable block 55 on the surface of the fixed bar 56 towards the center point of the fixed bar 56. When the movable block 55 moves, it drives the bottom connecting frame 57 and clamping block 58 to slide in the same direction as the movable block 55, thereby using the clamping block 58 to quickly clamp the workpiece. When the movable block 55 slides on the surface of the fixed strip 56, it also drives the limiting block 513 to slide. When the limiting block 513 slides, it will slide upward against the positioning block 512 through the groove 5130. When the positioning block 512 slides upward, it will drive the telescopic rod 510 to retract. After the clamping block 58 has finished clamping the workpiece, the telescopic rod 510 will be reset under the action of the fixed spring 511, so that the positioning block 512 will be re-inserted into the limiting block 513 for restriction. This prevents the use of traditional and cumbersome clamping methods, greatly saving the workpiece clamping time. Operators can quickly fix the workpiece in place and then immediately carry out subsequent processing, inspection and other work, reducing the standby time of the equipment and making the entire production process more compact and efficient. Especially in the case of batch production, it can significantly improve the overall production efficiency.

[0043] When the movable rod 54 slides, it also drives the fixed plate 61 to swing downwards inside the connecting frame 57 via the belt. When the fixed plate 61 swings downwards, it drives the sliding plate 63 and the support plate 65 to swing downwards. When the support plate 65 swings downwards, it moves to the bottom of the workpiece. By using workpieces of different sizes, the sliding plate 63 can be adjusted in length on the surface of the fixed plate 61. After adjustment, it returns to its original position under the action of the connecting spring 64, so that the support plate 65 fits against the bottom of the workpiece for restraint. When the sliding plate 63 slides on the surface of the fixed plate 61, it also drives the toothed plate 69 on the surface of the sliding plate 63 to abut against the insert block 68. The insert plate 66 swings away from the surface of the toothed plate 69. After adjustment, the insert plate 66 will reset under the action of the spiral spring 67, so that the insert block 68 and the insert plate 66 are reset. When the insert block 68 is reset, it will be re-inserted into the surface of the toothed plate 69 to restrict it and prevent the bottom of the workpiece from being suspended. For some large and heavy workpieces, if there is no effective support at the bottom and they are only fixed by the clamping force around them, the workpiece may be deformed under the long-term action of its own weight, which will destroy its original shape and dimensional accuracy. This improves the protection of the workpiece and enhances the stability of the workpiece transportation.
