Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a tooling for welding square tube frames. Background Technology

[0002] Welding fixtures are process equipment used to accurately position and reliably clamp products to be welded, facilitating assembly and welding. They have wide applications in the manufacturing industry. In existing technologies, welding fixtures typically use a pin connection between a full-circle pin hole and a pin hole on the chord ear plate to fix the chord. When the chord needs to be positioned on the welding fixture, the pin needs to be inserted into the full-circle pin hole. However, the common method of positioning and fixing square tube frames using a laser welding robot with a pin hole on the chord ear plate is not suitable for accurately positioning and fixing square tube frames of different shapes, which affects the welding work of the laser welding robot. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tooling for welding square tube frames.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design a tooling for welding square tube frames, including a tooling base plate, on which assembly holes and pin holes are evenly opened, and the tooling base plate is fastened to a tilting platform by bolts. Multiple push clamps and press clamps are welded on the tooling base plate, and a square tube component is set on the tooling base plate. The square tube component is held and fixed by the push clamps and press clamps, and corner brackets are inserted into the pin holes. The corner brackets are snapped into the bottom of the square tube component. Preferably, a square pin is provided at the bottom of the corner bracket, and the pin is inserted into a pin hole; Preferably, the push clamp includes a pad, the pad is welded to the tooling pad, the upper end face of the pad is fastened to the push clamp handle, the push clamp handle is rotatably hinged to a push rod, the push rod is threadedly connected to a threaded connector, and the threaded connector abuts against the side of the square tube. Preferably, the clamp includes a foot, which is welded to a tooling pad. A base is fastened to the foot. The base is rotatably connected to a "U"-shaped component and a rotating bracket via a first rotating shaft and a second rotating shaft. A clamp handle is welded to the top of the "U"-shaped component. A linkage is rotatably connected between the clamp handle and the rotating bracket. A clamping bolt is threaded to the end of the rotating bracket. The bottom of the clamping bolt abuts against the upper end of the square tube component. Preferably, the flipping platform is a square frame, and the upper surface of the flipping platform is evenly provided with multiple assembly holes.

[0005] The present invention proposes a tooling for welding square tube frames, which has the following advantages: by setting push clamps and pressure clamps to hold and fix the sides and top of the square tube frame, it is convenient for the subsequent welding robot to weld the square tube frame. At the same time, the flipping platform and the tooling pad are fixed by bolt assembly. Push clamps and pressure clamps are welded at different positions on the tooling pad to adapt to square tube parts of different shapes. Furthermore, when changing different fixtures, only the tooling pad installed on the flipping platform needs to be replaced, which is convenient and improves the efficiency of subsequent welding processing.

[0008] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0009] Reference Figure 1A fixture for welding square tube frames includes a fixture base plate 2. The surface of the fixture base plate 2 is evenly provided with assembly holes 3 and pin holes 4. The assembly holes 3 are evenly distributed along the surface of the fixture base plate 2. The fixture base plate 2 is fastened to the flipping platform 1 by bolts passing through the assembly holes 3. Multiple push clamps 5 and pressure clamps 6 are welded on the fixture base plate 2. The push clamps 5 and pressure clamps 6 are respectively welded and fixed on the fixture base plate 2 by their respective pads 9. A square tube part 8 is provided on the fixture base plate 2. The square tube part 8 is clamped and fixed by the push clamps 5 and pressure clamps 6. Angle brackets 7 are inserted into the pin holes 4 and are snapped into the bottom of the square tube part 8.

[0010] Reference Figure 6 The bottom of the corner bracket 7 is provided with a square pin 21. The pin 21 is inserted into the pin hole 4. The pin insertion method makes it easy to replace corner brackets 7 of different shapes to adapt to square tube parts 8 of different shapes, and the replacement process is convenient and quick.

[0011] Reference Figure 5 The push clamp 5 includes a foot 9, which is welded to the tooling plate 2. The upper end face of the foot 9 is fastened to the push clamp handle 20. The push clamp handle 20 is rotatably hinged to the push rod 18. The push rod 18 is threadedly connected to the threaded connector 19. The threaded connector 19 abuts against the side of the square tube 8. When clamping the side of the square tube 8, it is only necessary to rotate the threaded connector 19 so that the threaded connector 19 moves axially along the push rod 18 to abut against the side of the square tube 8.

[0012] Reference Figure 4 The clamp 6 includes a foot 9, which is welded to the tooling pad 2. A base 10 is fastened to the foot 9.
