Description

Technical Field

[0001] The present utility model relates to a welding fixture for a middle tile in an armored vehicle air intake cap. Background Art

[0002] The tile is an important part with a relatively complex shape and large usage quantity in the air intake cap of armored vehicles, and its structure is formed by welding two L-shaped parts, as shown in Figure 1 the figure. However, the L-shaped part itself is characterized by small width and long length, which is prone to large welding deformation after welding, resulting in that the tile cannot be installed into the grooves of the bottom plate and the top plate during the subsequent assembly of the air intake cap. Therefore, how to control the welding deformation of the tile is of great importance, and it is necessary to develop a welding fixture for the tile. Contents of Utility Model

[0003] In order to solve the above technical problems, the present utility model provides a welding fixture for a middle tile in an armored vehicle air intake cap with simple structure and reliable operation.

[0004] The technical solution adopted by the present utility model to solve the above technical problems is as follows: a welding fixture for a middle tile in an armored vehicle air intake cap, the tile comprises an upper L-shaped part and a lower L-shaped part, the fixture includes a base, a backup plate and a pressing plate, a groove is formed in the middle of the upper surface of the base, the lower L-shaped part is placed in the groove, the pressing plate for pressing the lower L-shaped part is arranged in the groove, a plurality of backup plates for placing the upper L-shaped part are longitudinally arranged on the side of the groove, and clamping components for clamping the upper L-shaped part and the lower L-shaped part together are arranged on the base.

[0005] In the above welding fixture for the middle tile in the armored vehicle air intake cap, the clamping component comprises a portal frame, a nut seat and a bolt, a plurality of portal frames are longitudinally arranged on the base, the portal frames span above the groove, each portal frame is provided with one nut seat, and a bolt is arranged in the nut seat.

[0006] In the above welding fixture for the middle tile in the armored vehicle air intake cap, the groove is arranged along the longitudinal direction of the base and penetrates through the base.

[0007] The beneficial effects of the present utility model are as follows: the cooperation of the pressing plate and the base of the present utility model can realize the fixation of the lower L-shaped part on the base, the cooperation of the base and the backup plate can combine the upper L-shaped part and the lower L-shaped part together, and the cooperation of the portal frame, the nut seat and the bolt can clamp the upper L-shaped part and the lower L-shaped part together. The fixture has the advantages of simple structural design, convenient clamping and disassembly, low manufacturing cost, and can effectively control the welding deformation of the tile, ensure the welding precision of the product, and ensure that the subsequent assembly requirements can be met. Brief Description of the Drawings

[0008] Figure 1 is a schematic structural view of the middle tile in the armored vehicle air intake cap.

[0009] Figure 2 is a schematic structural view of the present utility model. Detailed Description of the Embodiments

[0010] The present utility model is further described below with reference to the accompanying drawings and embodiments.

[0011] As shown in Figure 2 the figure, a welding fixture for a tile in an armored vehicle air inlet cap comprises a base 1, a backup plate 2, and a pressing plate 3. A groove is formed in the middle of the upper surface of the base 1, a lower L-shaped part 4 is placed in the groove, the groove is arranged longitudinally along the base 1 and penetrates through, the pressing plate 3 for pressing the lower L-shaped part 4 is arranged in the groove, a plurality of backup plates 2 for placing the upper L-shaped part 5 are longitudinally arranged on the side of the groove, and the base 1 is provided with a clamping component for clamping the upper L-shaped part 5 and the lower L-shaped part 4 together.

[0012] The clamping component comprises a gate-shaped frame 6, a nut seat 7, and a bolt 8. A plurality of gate-shaped frames 6 are longitudinally arranged on the base 1, the gate-shaped frames 6 span above the groove, each gate-shaped frame 6 is provided with one nut seat 7, and the bolt 8 is arranged in the nut seat 7.

[0013] The lower L-shaped part 4 can be fixed on the base 1 through the cooperation of the pressing plate 3 and the base 1, the upper L-shaped part 5 and the lower L-shaped part 4 can be combined together through the cooperation of the base 1 and the backup plate 2, and the upper L-shaped part 5 and the lower L-shaped part 4 can be clamped together through the cooperation of the gate-shaped frame 6, the nut seat 7 and the bolt 8.

[0014] The working process of the present utility model is as follows: in actual production and assembly welding, as shown in Figure 2 the figure, first pass the pressing plate 3 through the bent part of the lower L-shaped part 4 to fix the lower L-shaped part 4 on the pressing plate 3, then insert the pressing plate 3 into the groove of the base 1 to fix the lower L-shaped part 4 on the base 1, then lean the upper L-shaped part 5 against the backup plate 2, adjust the position, then tighten the bolts 8 in sequence to clamp the upper L-shaped part 5 and the lower L-shaped part 4 together, and finally weld the clamped tile. After welding, loosen the bolts 8 in sequence, pull out the pressing plate 3, and the tile can be taken out from the fixture.
