Description

Technical Field

[0001] The utility model belongs to the technical field of special-shaped plate processing, and more specifically relates to a special-shaped plate clamping device. Background Art

[0002] In many fields such as construction, metallurgy and mechanical processing, plate-shaped workpieces are one of the indispensable components for manufacturing various equipment, such as wood and steel plates. Plate-shaped workpieces are spliced ​​through welding and other technologies to form a complete structure. Before splicing, according to the equipment requirements, the plate-shaped workpieces need to be milled to meet the equipment splicing requirements.

[0003] Most of the plate-shaped workpieces required in various fields are flat plate structures. The milling operation of such flat plate structures is relatively easy, and they can be precisely milled after being fixed with some common clamping devices on the market. However, according to the needs of existing equipment, some special-shaped plates are required in some cases, such as arc-shaped plates with a part extending downward on both sides. Such special-shaped plates are often difficult to fix with conventional plate clamping devices, resulting in the inability to ensure milling accuracy, thus failing to meet equipment requirements.

[0004] For example, the Chinese patent application number is CN201511023486.1, and the patent document with the publication date of March 23, 2016 discloses a clamping and fixing seat for welding plate-like workpieces, including a base plate, on which two relatively positioned movable baffles are arranged, the movable baffles are connected to a driving mechanism, and the driving mechanism can drive the two movable baffles to move in the same direction or opposite directions in the horizontal direction, and the inner side surface of the movable baffle is provided with at least one plug, which is connected to a plug cylinder. The clamping and fixing seat is provided with two relatively positioned movable baffles on the base plate, so that the workpiece to be welded can be clamped between the two movable baffles. Since the end faces of most welded workpieces may not be flat, a plug is provided on each movable baffle, and the plug is connected to the plug cylinder, so that the workpiece with a non-flat end face can be fixed and clamped.

[0005] Although the above scheme can be used for welding workpieces with uneven end faces, it is to tighten and fix the workpiece from the outside. When it is used for the arc-shaped plates with a portion of both sides extending downward as mentioned above, it is difficult to ensure the fixing effect, which affects the milling accuracy.

[0006] The Chinese patent application number is: CN202110941355.0, and the patent document with the publication date of October 8, 2021 discloses a tightening mechanism, a side clamping device, an accessory welding tooling and a welding method, including a side tightening block, a first tightening mounting plate for pushing the side tightening block to tighten the workpiece, one side of the side tightening block is hinged to the first tightening mounting plate, and the other side is provided with at least one universal pressure head. The first tightening mounting plate is provided with a plurality of movable push rods along its tightening direction, and the push rods are used to directly and / or indirectly be universally rotatably connected with each universal pressure head. The first tightening mounting plate pushes the side tightening block to abut against the side wall of the workpiece. Depending on the swing angle of the side tightening block around the hinge, the universal pressure head matches the swing angle of the side tightening block for corresponding rotation adjustment, and the side tightening block is attached to the side wall of the workpiece by relying on the hinge and the universal pressure head.

[0007] This solution can achieve clamping and fixing of the special-shaped plate to a certain extent by setting up a tightening mechanism and a side clamping mechanism, but it is also not suitable for the arc-shaped plate mentioned above with a part of the two sides extending downward, and the fixing effect is not ideal.

[0008] In particular, both of the above solutions clamp and tighten the plate from the outside of the special-shaped plate, and this outer clamping device is likely to affect the operation of the milling equipment due to the space it occupies, and it is difficult to perform precise milling on the position of the plate located around the clamping part. Summary of the invention

Therefore, the scope of the present invention is limited only by the appended claims.

[0033] Example 1

[0034] A special-shaped plate clamping device is used in plate milling operations to clamp and fix special-shaped plates such as arc-shaped plates with a portion of both sides extending downward, thereby facilitating the operation of the milling equipment. The specific structure and technical effects are described in detail below.

[0035] like Figure 1 As shown, the clamping device includes a workbench 1, on which are mounted a side clamping device 2, an upper clamping device 3 and a point clamping device 4. The side clamping device 2 includes a side clamping block 21 and a lateral adjustment mechanism for adjusting the lateral position of the side clamping block 21, and the side clamping block 21 is located on the outside of the lateral adjustment mechanism. The upper clamping device 3 includes an upper clamping member 31 and a vertical adjustment mechanism for adjusting the vertical position of the upper clamping member 31, and the upper clamping member 31 is located on the upper side of the vertical adjustment mechanism. The point clamping device 4 includes a spherical clamping block 41 and a point adjustment mechanism for adjusting the vertical position of the spherical clamping block 41.

[0036] like Figure 2 As shown, when the milling equipment is working, the side clamping device 2 and the upper clamping device 3 can clamp and fix the special-shaped plate from the inside to the outside of the special-shaped plate in the horizontal and vertical directions, thereby improving the fixing effect of the special-shaped plate. Moreover, since the side clamping device 1 and the upper clamping device 2 are located on the inside of the special-shaped plate, they will not affect the operation of the milling equipment on the outside, thereby improving the milling effect of the special-shaped plate. In particular, by setting the point clamping device 4, it is possible to achieve the tightening of some small irregular positions at the bottom of the special-shaped plate, thereby further improving the fixing effect of the special-shaped plate.

[0037] Specifically, the side tightening block 21 is detachably fixedly mounted on the transverse adjustment mechanism, so as to facilitate replacement and adaptation according to different types of special-shaped plates. The transverse adjustment mechanism includes a transverse fixing frame 22 and a transverse telescopic member 23. The transverse fixing frame 22 is provided with a plurality of mounting holes along the height direction. The transverse telescopic member 23 is fixedly mounted in the mounting holes by bolts, and the side tightening block 21 is mounted on the transverse telescopic member 23. In this embodiment, the transverse telescopic member 23 is a cylinder.

[0038] The vertical adjustment mechanism includes a vertical fixing frame 32 and a vertical telescopic member 33. The vertical fixing frame 32 is provided with a plurality of mounting holes in the horizontal direction. The vertical telescopic member 33 is fixedly installed in the mounting holes by bolts, and the upper clamping member 31 is installed on the vertical telescopic member 33. In this embodiment, the vertical telescopic member 33 and the transverse telescopic member 23 are cylinders. The upper clamping member 31 adopts a pneumatic suction cup, which can suck the special-shaped plate to prevent the special-shaped plate from bouncing up due to vibration during the milling process and affecting the milling work.

[0039] The arrangement of the transverse telescopic member 23 and the vertical telescopic member 33 can realize the telescopic of the clamping device, which can better fix from the inside, and make the device applicable to special-shaped panels of different sizes. Similarly, by installing the transverse telescopic member 23 and the vertical telescopic member 33 in different mounting holes, the applicability of the device to special-shaped panels of different sizes is further improved.

[0040] At least one point clamping device 4 is installed in the middle of the workbench 1, and multiple point clamping devices 4 are installed at intervals around the middle of the workbench 1. In this embodiment, there is one point clamping device 4 in the middle, and four point clamping devices 4 are arranged at equal intervals around the point clamping device 4. A guide rod is fixedly installed on the upper side of the point adjustment mechanism, and a guide sleeve sleeved on the guide rod is fixedly connected to the lower side of the spherical top clamping block 41. A spring is sleeved on the guide rod between the guide sleeve and the upper side of the point adjustment mechanism, and the two ends of the spring are respectively connected to the guide sleeve and the upper side of the point adjustment mechanism. By setting the spring, a certain avoidance space is provided for the spherical top clamping block 41, which avoids the point clamping device 4 from being damaged by the spherical top clamping block 41 squeezed by the protruding part of the bottom of the special-shaped plate.

[0041] It is worth mentioning that the positions where the side clamping block 21 and the upper clamping member 31 contact the workpiece, as well as the spherical clamping block 41 are covered with flexible pads that can protect the panel when clamping the panel, thereby reducing the probability of damage to the panel.

[0042] In summary, the special-shaped plate clamping device of the present embodiment can effectively fix the special-shaped plate without affecting the operation of the outer milling device, thereby improving the milling effect of the special-shaped plate.
