[0032] As attached Figure 1 and attached Figure 2 The diagram shows the main body of a spider car frame. The main body primarily includes a frame A, support plates B welded to the upper and lower surfaces at both ends of the frame, a flange cylinder C welded to one end of the frame, and a connecting frame D welded to the end of the frame away from the flange cylinder. The frame mainly consists of a U-shaped groove formed by bending, a partition plate welded to the U-shaped groove, and a panel welded to the upper surface of the U-shaped groove. The flange cylinder consists of a cylinder, a flange plate at the top of the cylinder, a reinforcing plate below the flange plate, and multiple ribs between the reinforcing plate and the flange plate. For the welding of the flange cylinder and the support plate, it is required to ensure the coaxiality and orientation of the flange cylinder and the mounting holes on the frame. The upper and lower surfaces at both ends of the frame, relative to the support plates, need to ensure positional accuracy and parallelism. Therefore, this embodiment provides a riveting and welding fixture for the main body of a spider car frame.

[0033] Example 1

[0034] As attached Figure 3 Appendix Figure 4 and attached Figure 6 As shown, this embodiment provides a riveting and welding fixture for the main body of a spider vehicle frame, including a base plate 1 and a first positioning component disposed on the base plate for positioning the frame body A, a second positioning component for positioning the flange cylinder C, and a third positioning component for positioning the support plate B, wherein:

[0035] The first positioning component includes multiple baffles 2 disposed at one end of the base plate 1 and side positioning seats 3 disposed on one side of the base plate near its two ends; the baffles are used to position the ends of the frame, and the side positioning seats are used to position the sides of the frame. In this embodiment, the number of baffles is at least two, preferably right-angled triangular plates with the vertical surface as the positioning surface. The side positioning seat 3 in this embodiment includes a fixed base plate 3.1, a positioning panel 3.2 disposed at one end of the fixed base plate, and a connecting plate 3.3 disposed on the back of the positioning panel. Preferably, a panel 3.4 is also provided at the end of the connecting plate for connecting to the positioning plate of the third positioning component.

[0036] The second positioning component includes a positioning frame 4 bolted to the flange body C and support frames 5 located on both sides of the frame on the base plate. The two ends of the positioning frame 4 are detachably mounted on the two support frames 5. Preferably, in this embodiment, the positioning frame 4 includes a frame 4.1 and a circular positioning plate 4.2 located on the lower surface of the frame. The circular positioning plate matches the flange of the flange body and has multiple mounting holes 4.2.1 for connecting to the flange body. In this embodiment, the central axis of the circular positioning plate is coaxial with the central axis of the mounting holes on the frame for mounting the flange body. The top of the support frame 5 has a limiting groove 5.1, and the positioning frame is positioned within the limiting groove and fixed by pins 6 at both ends of the limiting groove. When positioning the flange body, first insert the flange body into the mounting hole of the frame and adjust its installation orientation. Then, roughly adjust it to the correct position according to the hole position of the circular positioning plate on the positioning frame. Finally, fix the positioning frame on the support frame and use bolts to securely connect the flange body to the circular positioning plate, ensuring the flange body's position is fixed.

[0037] In another embodiment, the positioning frame and the support frame are connected as follows: the top of the support frame is provided with a limiting groove, one end of the positioning frame is rotatably installed in the limiting groove by a pin, and the other end is fixed in the limiting groove by pins at both ends of the limiting groove. This flip-up positioning frame design makes it easy to quickly open the positioning frame and remove the riveted and welded vehicle frame body; it also facilitates the quick lowering and fixing of the positioning frame to fix the flange cylinder.

[0038] The third positioning component includes a first positioning seat 7 for positioning the outer sides of both ends of the support plate B, and at least one positioning pin 8 for limiting the ends of the support plates through through holes on the upper and lower support plates B, which is screwed or inserted into the base plate, as shown in the attached figure. Figure 2 and attached Figure 5As shown. Preferably, the first positioning seat 7 in this embodiment includes a positioning base plate 7.1 for positioning the outer side of the lower support plate B, a positioning vertical plate 7.2 vertically disposed on the positioning base plate for positioning the side of the upper support plate, and a connecting rib plate 7.3 disposed between the positioning base plate and the positioning vertical plate. In this embodiment, the positioning base plate and the positioning vertical plate of the first positioning seat are used to position the outer sides of the lower support plate and the upper support plate, respectively, while the ends of the upper support plate and the lower support plate are positioned using positioning pins. In this embodiment, two positioning pins are used for positioning to ensure positioning accuracy.

[0039] Because the U-shaped groove of the frame is formed by bending, there is an error in the height of the two sides of the U-shaped groove. If the upper support plate is placed directly on the upper surface of the frame, it may not be possible to guarantee its level with the lower support plate. Therefore, this embodiment also includes two positioning plates 9, which are detachably mounted on the first positioning seat 7. The upper surfaces of the two positioning plates 9 are on the same horizontal plane and parallel to the bottom plate 1, and are used to support the two ends of the upper support plate B. This ensures that the first support plate and the second support plate are parallel to each other.

[0040] To ensure the stability of the positioning plate, in this embodiment, the outer surface of the first positioning seat 7 on the same side as the side positioning seat 3 is on the same vertical plane as the outer surface of the side positioning seat (i.e., the panel on the connecting plate of the side positioning seat away from the positioning panel is coplanar with the positioning vertical plate). Both ends of the positioning plate 9 are fixedly mounted to the first positioning seat 7 and the side positioning seat 3 respectively using screws. The other end of the support plate B is provided with a support seat 10 on the same vertical plane as the outer surface of the first positioning seat 7. Both ends of the positioning plate 9 are fixedly mounted to the first positioning seat 7 and the support seat 10 respectively using screws. In this embodiment, the support seat 10 has the same structure as the first positioning seat 7.

[0041] Since both the upper and lower support plates protrude from the ends of the frame, the positioning surface of the baffle 2 in this embodiment is provided with clearance openings 2.1 at the upper and lower ends to avoid the upper and lower support plates, respectively.

[0042] In practice, firstly, the lower support plates located at both ends of the frame are positioned on the base plate using the third positioning component and positioning pins. Then, the frame is positioned on the base plate using the first positioning component, completing the riveting and welding of the lower support plates to the frame. Next, the positioning plate is fixed on the first positioning seat and the support seat / side positioning seat. The upper support plate is positioned on the frame using the third positioning component and positioning pins, and then riveted and welded to the frame. Finally, the flange cylinder is hoisted into the mounting hole of the frame and its position is adjusted. The positioning frame is fixed on the support frame, and the flange cylinder is fixed to the circular positioning plate with bolts. The flange cylinder is then riveted and welded to the frame. After riveting and welding, the positioning plate is removed, the positioning pins are pulled out, and the positioning frame is removed so that the workpiece can be hoisted out.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
