Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical tooling, and in particular relates to a pressing tooling for segmented plates. Background Art

[0002] When welding the segmented plates and the T-rows, if the segmented plates are not fixed on the welding platform, the segmented plates will bend after welding and the two ends will warp and deform.

[0003] Therefore, during welding, a clamping fixture is needed that can firmly fix both ends of the segmented plate in the length direction to limit its deformation. Utility Model Content

[0004] The utility model aims to provide a clamping tool for segmented plates, which is characterized in that the segmented plates are placed on the surface of a working platform, and the two ends of the segmented plates in the length direction are respectively clamped by the clamping tool;

[0005] The clamping tooling includes a step block and a pressing block. The thickness of the step block is the same as that of the segmented plate. A back plate extends upward from the side of the step block away from the segmented plate. The two ends of the pressing block are respectively located on the upper surfaces of the step block and the segmented plate, and one end of the pressing block facing the step block abuts against the back plate. The pressing block is fixed to the working platform by fasteners.

[0006] Furthermore, a first scale line for positioning the segmented plate is provided on a side of the step block.

[0007] Furthermore, the back surface of the back plate is provided with numbers engraved thereon indicating the current height of the step block, and the numbers are matched with a second scale line locating the horizontal height indicated by the numbers.

[0008] Furthermore, a long U-shaped through hole is provided in the middle of the pressing block, and the fastener is a locking pin. The pressing block is fixed to the tooling platform by cooperating with the through hole on the upper surface of the working platform through the locking pin.

[0009] Furthermore, a backrest is extended upwardly from one end of the pressing block toward the step block, and a round through hole is arranged in the middle of the backrest.

[0010] Compared with the prior art, the beneficial effects of the utility model are mainly reflected in:

[0011] 1. The utility model can realize the compression of the segmented plate only by the step block, the pressure block and the locking pin, and has a simple structure and is easy to install and disassemble. And by making the thickness of the step block consistent with the thickness of the segmented plate, the pressure block is pressed down horizontally, so that the compression of the segmented plate is more stable and will not shake easily.

[0012] 2. In the utility model, the end of the pressing block is close to the step block, and the placement position of the segmented plate can be corrected by the scale lines on the side of the pressing block.

[0013] 3. When the thickness of the step block itself is different from the thickness of the segmented plate, a pad of fixed thickness can be placed on the upper surface of the step block and confirmed by the scale line on its back plate to achieve levelness of both ends of the pressing block, thereby making the pressing of the segmented plate by the pressing block more stable.

[0017] The following will be described in more detail with reference to schematic diagrams, in which a preferred embodiment of the present invention is shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the present invention.

[0018] like Figure 1 As shown, a clamping tool for segmented plates, wherein the segmented plate 1 is placed on the upper surface of a working platform, and the upper surface of the working platform is provided with a plurality of equally spaced circular holes for matching with the tooling on its upper surface and fixing it.

[0019] The segmented plate 1 is placed on the upper surface of the working platform. When it is welded to the T row, the high temperature of welding will cause the surface of the T row to bend, and its two ends will be lifted and deformed. Therefore, a device is needed to clamp the two ends of the tooling platform to limit its deformation during welding.

[0020] The utility model uses two sets of pressing tools to press the two ends of the segmented plate 1, and the two sets of pressing tools have the same structural settings, including a pressing block 3 and a step block 2. Among them, the step block 2 is arranged on the upper surface of the working platform at the end positions of the two ends of the segmented plate 1 in the length direction, and a back plate 21 is extended upward from the side of the side away from the segmented plate 1, and the back plate 21 is perpendicular to the upper surface of the step block 2 to form a right angle.

[0021] The pressing block 3 is in the shape of a long strip, and a backrest 31 extends upward from any end of the pressing block 3. The backrest 31 is vertically arranged with the pressing block 3 and forms a right angle, which is used to cooperate with the right angle formed between the step block 2 and the back plate 21. When the end of the pressing block 3 is pressed on the upper surface of the step block 2, the back side of the backrest 31 abuts against the front side of the back plate 21. A long U-shaped through hole is provided in the middle of the long pressing block 3 for fasteners to pass through and fix with the working platform.

[0022] The thickness of the step block 2 of the utility model is the same as the thickness of the segmented plate 1 to be welded. When the two ends of the pressing block 3 are placed on the upper surfaces of the segmented plate 1 and the step block 2, the pressing block remains horizontal. When the pressing block 3 is fixed to the working platform using fasteners, the contact surface between the bottom surface of the pressing block 3 and the segmented plate 1 and the step block 2 is the largest, making the pressing of the segmented plate 1 by the pressing block 3 more stable.

[0023] A first scale line 32 is provided on the side of the pressing block 3. When the segmented plate 1 is placed on the upper surface of the working platform and pressed, it is also necessary to check whether the placement positions of the segmented plate 1 are consistent. The position of the segmented plate 1 can be fine-tuned through the engraved first scale line 32.

[0024] The utility model provides a fastener as a quick locking pin 4, which can quickly fix the pressing block 3 on the upper surface of the tooling platform, and the disassembly is also faster.

[0025] A circular through hole 33 is provided in the middle of the backrest 31. The provision of the circular through hole 33 can reduce the manufacturing cost of the pressing tooling and reduce the weight of the pressing block 3. On the other hand, the circular through hole can also facilitate taking and transferring.

[0026] refer to Figure 2 When the thickness of the segmented plate 1 changes, the horizontal heights of the segmented plate 1 and the step block 2 are inconsistent, which will make the pressing block 3 unstable after being pressed, reducing the stability of the pressing. In contrast, we set a number 22 engraved on the back surface of the back plate 21. The number 22 is the horizontal height at which it is located based on the working platform. The number 22 is engraved with a second scale line 23 for locating the horizontal height indicated by the number. The second scale line 23 extends to the adjacent side of the back plate 21 for easy comparison. When the thickness of the segmented plate 1 is greater than the thickness of the current step block 2, we can only place a gasket 5 of fixed thickness on the upper surface of the step block 2 to raise the "actual height" of the step block 2 to make it the same as the thickness of the segmented plate 1, thereby making the pressing block 3 horizontal and maintaining the stability of the pressing.

[0027] The above are only preferred embodiments of the present invention and do not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, may make any equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which shall be deemed as the content of the technical solution of the present invention and still fall within the protection scope of the present invention.
