Technical Field

[0001] The utility model belongs to the technical field of jigs, and particularly relates to a box body fixing device. Background Art

[0002] A jig refers to a device used in the mechanical manufacturing process to fix a processing object, make it occupy a correct position, and accept construction or inspection. During the welding process of a box body structure workpiece, the two sides of the box body are usually abutted and fixed by two relatively arranged jigs to achieve the purpose of welding and fixing. However, for a box body structure workpiece with a relatively low hardness, during the abutting and fixing process, if the extrusion force is too large, the box body is likely to be deformed, and if the extrusion force is too small, the workpiece is likely to be displaced, affecting the welding effect. Content of the Utility Model

[0003] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a main box body fixing device. By forming a corner structure with a moving part and an abutting block, the corners of the extension part of the main box body are clamped and fixed, which can ensure that the main box body is not easily displaced during welding and can also prevent the main box body from being extruded and deformed.

[0004] A main box body fixing device includes a fixing mechanism for fixing the main box body and a rotating disk connected to a driving device. The rotating disk is connected to the fixing mechanism, and the driving device drives the rotating disk to rotate, thereby driving the fixing mechanism to rotate. The fixing mechanism includes a moving part driven by a first cylinder and an abutting block driven by a second cylinder. The moving part is triangular, and two sides of the moving part are respectively provided with abutting blocks. The moving part and the two abutting blocks move towards each other to form a corner structure to clamp and fix the corners of the extension part of the main box body.

[0005] Preferably, the fixing mechanism further includes a cross block. The first cylinder is installed on the protruding part of the cross block, and a guide rod is also installed on the protruding part of the cross block. The guide rod is connected to the moving part.

[0006] Preferably, an installation groove for accommodating the first cylinder is formed on the protruding part of the cross block, and a guide hole for embedding the guide rod is arranged at the position of the protruding part corresponding to the installation groove.

[0007] Preferably, the fixing mechanism further includes a bottom plate connected to the rotating disk. A fixing plate is installed on the bottom plate. There are four fixing plates, and the four fixing plates enclose a rectangular space for clamping the main box body.

[0008] Preferably, the moving part is located inside the rectangular space, and the triangular top angle part of the moving part is a copper block.

[0009] Preferably, the second cylinder is installed on the fixing plate, outside the rectangular space. The abutting block is connected to the driving end of the second cylinder, inside the rectangular space, and is used in cooperation with the moving part.

[0010] Preferably, the rotating disk is connected to the mounting seat. The mounting seat is drivingly connected to the driving device through the mounting plate. The mounting seat is internally provided with a bushing for connecting to the driving shaft of the driving device.

[0011] The beneficial effects of the present utility model are as follows: For this main box body fixing device, the first cylinder drives the moving part to move, and the second cylinder drives the abutting block to move. By utilizing the mutual cooperation between the triangular moving part and the abutting blocks arranged on both sides of the moving part, a corner structure is formed to clamp and fix the corners of the extension part of the main box body. Clamping and fixing the main box body at the corners can prevent the main structure of the main box body from deforming. At the same time, the corner structure formed by the moving part and the abutting blocks can also shape the corners of the extension part of the main box body. In addition, the driving device arranged externally drives the rotating disk and the fixing mechanism to rotate, thereby driving the main box body to rotate, which can adjust the angle of the main box body during welding and is beneficial to meeting different welding requirements.

Detailed Embodiments

[0018] Embodiment 1

[0019] As Figure 1As shown in the figure, a box body fixing device includes a fixing mechanism 3 for fixing the main box body 1 and a rotating disk 4 connected to a driving device. The rotating disk 4 is connected to the fixing mechanism 3, and the driving device drives the rotating disk 4 to rotate, thereby driving the fixing mechanism 3 to rotate. Specifically, the rotating disk 4 is connected to a mounting base 5, and the mounting base 5 is drivingly connected to the driving device through a mounting plate 6. The mounting base 5 is internally provided with a bushing 7 for connecting to the driving shaft of the driving device. Among them, the driving device (not shown in the figure) is an external machine tool device, and its structure is not specifically defined here. Its main function is to provide driving force for the rotation of the rotating disk 4 driving the fixing mechanism 3.

[0020] As Figure 1 shown, in this embodiment, an extension part 2 is connected to the main box body 1. As Figure 2 、 Figure 3 shown, the fixing mechanism 3 includes a moving part 10 driven by a first cylinder 9 and a butting block 11 driven by a second cylinder 12. Specifically, the moving part 10 is triangular, and two sides of the moving part 10 are respectively provided with butting blocks 11. The moving part 10 and the two butting blocks 11 move towards each other to form a corner structure to clamp and fix the corners of the extension part 2 of the main box body 1. Clamping and fixing the main box body 1 at the corners can avoid deformation of the main structure of the main box body 1. At the same time, the corner structure formed by the moving part 10 and the butting block 11 can also shape the corners of the extension part 2 on the main box body 1.

[0021] As Figures 2 to 4 shown, the fixing mechanism 3 further includes a cross block 8. The first cylinder 9 is installed on the protruding part of the cross block 8. A guide rod 13 is also installed on the protruding part of the cross block 8, and the guide rod 13 is connected to the moving part 10. Further, an installation groove 801 for accommodating the first cylinder 9 is formed in the protruding part of the cross block 8, and a guide hole 802 for embedding the guide rod 13 is provided at a position corresponding to the installation groove 801 on the protruding part. The driving end of the first cylinder 9 drives the moving part 10 to move to adjust the position of the moving part 10. At the same time, the guide rod 13 moves with the moving part 10, which can improve the stability of the moving part 10 when moving. Among them, the first cylinder 9 is set to drive synchronously to ensure that the moving distances, speeds, etc. of each moving part 10 are the same; the second cylinder 12 is set to drive synchronously to ensure that the moving distances, speeds, etc. of each butting block 11 are the same.

[0022] As Figure 2 、 Figure 3As shown, the fixing mechanism 3 further includes a bottom plate 15 connected to the rotating disk 4. A fixing plate 14 is installed on the bottom plate 15. There are four fixing plates 14, and the four fixing plates 14 enclose a rectangular space for clamping the main box body 1. Among them, the moving member 10 is located inside the rectangular space. The triangular top corner part of the moving member 10 is a copper block, which plays a role in heat dissipation during welding by using the heat conduction property of the copper block. The second cylinder 12 is installed on the fixing plate 14, located outside the rectangular space. The abutting block 11 is connected to the driving end of the second cylinder 12, located inside the rectangular space, and is used in cooperation with the moving member 10.

[0023] Working principle: For this box body fixing device, during use, the box body fixing device is connected to an external driving device through the mounting plate 6, and then the extension part 2 of the main box body 1 is clamped in the clamping groove formed by the moving member 10 and the abutting block 11 (as Figure 3 shown). Then, the first cylinder 9 is started to drive the moving member 10 to move, and the second cylinder 12 is started to drive the abutting block 11 to move. By using the mutual cooperation between the triangular moving member 10 and the abutting blocks 11 arranged on both sides of the moving member 10, a corner structure is formed to clamp and fix the corners of the extension part 2 of the main box body 1. During the welding process, the rotating disk 4 is driven to rotate by an external driving device, so as to drive the fixing mechanism 3 and the main box body 1 thereon to rotate to meet different welding requirements.
