Technical Field

[0001] The utility model relates to the field of positioning tooling, in particular to an auxiliary tooling for installing fasteners in a narrow space. Background Art

[0002] During the welding process of sheet metal parts, it is necessary to clamp and position the workpiece and dock the connecting parts between the workpieces to facilitate welding. However, on both sides of the two positioning and adapting and docking workpieces, after synchronous opening, the gap at the connection between the two is small, the space is very limited, and the driving structure is not easy to install, resulting in very limited positioning accuracy. At the same time, the two driving structures interfere with each other, and the synchronous opening and positioning on both sides cannot be achieved, affecting the positioning accuracy of the tooling.

[0003] Therefore, aiming at the problem that the space between workpieces is very narrow after the existing positioning tooling clamps the workpiece, resulting in very limited positioning accuracy, an auxiliary tooling for installing fasteners in a narrow space can be designed to facilitate simultaneous opening on both sides and ensure the positioning accuracy. Summary of the Utility Model

[0004] In order to overcome the problem that the space between workpieces is very narrow after the existing positioning work clamps the workpiece, resulting in very limited positioning accuracy.

[0005] The technical solution of the utility model is: an auxiliary tooling for installing fasteners in a narrow space, including a first fixing seat and a second fixing seat, further including a lifting cylinder and a workpiece body. A clamping cylinder is fixedly installed on the side of the upper end of the first fixing seat, a tooling seat is fixedly installed on the front end face of the second fixing seat, a top pressing plate is rotatably installed at the output end of the clamping cylinder, pressing blocks are arranged on both sides of the end of the top pressing plate far from the clamping cylinder, a front stop block is installed at the front end of the tooling seat, a connecting seat is arranged on the surface of the lifting cylinder, a hinge seat is arranged at the upper end of the connecting seat, and a positioning stop block is arranged at the upper end of the hinge seat.

[0006] Preferably, the lower end of the first fixing seat is detachably connected to the tooling platform, the front end of the second fixing seat is detachably connected to the tooling platform, and the rear end face of the lifting cylinder is detachably connected to the tooling platform.

A clamping cylinder 4 is fixedly installed on the side of the upper end of the first fixing seat 1, a tooling seat 3 is fixedly installed on the front end face of the second fixing seat 2, the output end of the clamping cylinder 4 is rotatably installed with a pressing plate 5, both sides of the end of the pressing plate 5 away from the clamping cylinder 4 are provided with pressing blocks 6, a front stop block 7 is installed at the front end of the tooling seat 3, a connecting seat 9 is arranged on the surface of the lifting cylinder 8, a hinge seat 10 is arranged at the upper end of the connecting seat 9, and a positioning stop block 11 is arranged at the upper end of the hinge seat 10. Fixing the first fixing seat 1 and the second fixing seat 2 on the tooling platform facilitates the clamping and fixing of the workpiece body 12, and the upper end of the workpiece body 12 is tightly clamped by the pressing blocks 6, and the end of the workpiece body 12 is positioned by the positioning stop block 11, which facilitates the butt joint between the workpiece bodies 12. The lifting cylinder 8 can drive the two positioning stop blocks 11 to move synchronously, which is convenient for synchronous opening in a narrow space and ensures the positioning accuracy.

[0022] Please refer to 1 Figure 2 and Figure 3 , in this embodiment, two tooling seats 3 are symmetrically arranged on the left and right sides of the second fixing seat 2. A workpiece groove is arranged on the upper end surface of the tooling seat 3. The lifting cylinder 8 is located inside the tooling seat 3. The upper end of the front stop block 7 is adapted to the workpiece groove, and the workpiece body 12 is adapted to the workpiece groove. The workpiece body 12 is placed in the workpiece groove, and the front stop block 7 limits the front side of the workpiece body 12, which is convenient for receiving the workpiece.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , in this embodiment, a fulcrum seat 41 is fixedly installed on the surface of the fixed end of the clamping cylinder 4. A hinge plate 42 is rotatably installed on the surface of the upper end of the fulcrum seat 41. The upper end of the hinge plate 42 is rotatably connected to the pressing plate 5. The pressing plate 5 is designed in a T-shaped structure. Two pressing blocks 6 are arranged on the left and right sides of the pressing plate 5. The clamping cylinder 4 is used to push the rear end of the pressing plate 5 to move, and through the connection of the hinge plate 42, the front end of the pressing plate 5 is synchronously turned over, so that the pressing blocks 6 tightly fix the upper end of the workpiece body 12, which is convenient for clamping.

[0024] Please refer to Figure 1 ,Figure 4 , Figure 5 , in this embodiment, there are two connecting seats 9 arranged on both sides of the lifting cylinder 8. The upper end of the connecting seat 9 is rotatably connected to the lower end of the hinge seat 10. The hinge seat 10 is designed in an H-shaped structure. The lower end of the hinge seat 10 is rotatably connected to the positioning stop block 11. There are two positioning stop blocks 11 arranged symmetrically. An extension plate 111 is arranged on the surface of the positioning stop block 11. One end of the extension plate 111 away from the positioning stop block 11 is rotatably connected to the output end of the lifting cylinder 8. The output end of the lifting cylinder 8 drives the positioning stop block 11 to move, and through the rotational connection of the hinge seat 10, the upper end of the positioning stop block 11 moves synchronously, facilitating the positioning of the end of the workpiece body 12 and the docking between workpieces.

[0025] During operation, the first fixing seat 1 and the second fixing seat 2 are fixed on the tooling platform, and the workpiece body 12 is placed in the workpiece groove. The front stop block 7 limits the front side of the workpiece body 12 to facilitate receiving the workpiece. Then, the clamping cylinder 4 is used to push the rear end of the pressing plate 5 to move, and through the connection of the hinge plate 42, the front end of the pressing plate 5 flips synchronously, so that the pressing block 6 presses and fixes the upper end of the workpiece body 12 to achieve clamping. Moreover, the output end of the lifting cylinder 8 drives the positioning stop block 11 to move, and through the rotational connection of the hinge seat 10, the upper end of the positioning stop block 11 moves synchronously, facilitating the positioning of the end of the workpiece body 12 and the docking between workpieces. Since the space between workpieces is small, the lifting cylinder 8 drives the positioning stop block 11 to move, facilitating the synchronous opening and closing on both sides in a narrow space, preventing mutual interference between driving parts, and ensuring the positioning accuracy.

[0026] Through the above steps, the lifting cylinder 8 can drive the two-sided positioning stop blocks 11 to move synchronously, facilitating the synchronous opening in a narrow space and ensuring the positioning accuracy, so as to solve the problem that the space between workpieces is very narrow after the existing positioning work clamps the workpiece, resulting in very limited positioning accuracy.
