Description

Technical Field

[0001] The utility model relates to the field of welding, in particular to a riveting and welding tool for a V-shaped roller bracket. Background Art

[0002] The structure of the existing V-type roller bracket is as shown in the attached manual. Figure 1 and attached Figure 2 As shown, the V-shaped roller support is welded together from two opposing side panels (a), two crossbeams (b) connecting the two side panels, multiple center struts (c) located in the middle of the crossbeams for mounting rollers, and multiple ribs (d) connecting the side panels and the crossbeams. When welding this V-shaped roller support, the weld spacing between the top slope of the side panels and the center struts must be precisely controlled to accommodate the inclined rollers on both sides. The weld spacing between the two center struts for mounting the horizontal rollers in the center must also be precisely controlled.

[0003] The structure of the existing V-type roller bracket riveting tooling is as shown in the attached manual. Figure 3 As shown, the riveting welding fixture includes a welding platform 1 and a fixing member 2 provided on the welding platform for fixing the bottom of the side panel a, a limiting member 3 for positioning the top inclined surface of the side panel a, and a plurality of positioning members 4 for positioning the middle pillar c, wherein the positioning member also serves as a formwork for the crossbeam. During welding, the bottom of the side panel is fixed on the fixing member, the top inclined surface of the side panel is supported by the limiting plate of the limiting member, and the crossbeam is placed between the two side panels with the positioning member as a formwork. At the same time, the two ends of the crossbeam are overlapped with the fixing member, and the crossbeam and the side panel are spot welded. Then the middle pillar is placed on the positioning member, and the middle pillar and the crossbeam are spot welded. Finally, the rib plate is spot welded between the side panel and the crossbeam. After the above welding is completed, the bracket is removed, and the standard roller is installed in the corresponding position of the bracket to check whether the welding of the bracket meets the requirements. After the inspection shows that it meets the requirements, the bracket is then installed in the welding fixture for full welding. The existing riveting welding fixture has the following defects:

[0004] 1. It is necessary to remove the bracket and install the standard roller for inspection. After the inspection is completed, the tooling needs to be reinstalled to complete the welding, which is troublesome and inefficient.

[0005] 2. The crossbeam is positioned only by the positioning block as a template, and manual support welding is required. The operation is difficult and the welding quality cannot be guaranteed.

[0006] Based on this, the present application provides a V-shaped roller bracket riveting and welding tool that does not require the bracket to be removed for inspection and can fix the position of the beam to solve the above problems. Utility Model Content

[0033] Example 1

[0034] This embodiment provides a V-shaped roller bracket riveting welding tool, as shown in the attached Figure 4 As shown, it includes a welding platform 1 and a fixing member 2 arranged on the welding platform for fixing the bottom of the side panel a, a limiting member 3 for positioning the top inclined surface of the side panel a, a plurality of positioning members 4 for positioning the middle pillar c, and an inspection shaft 5 for inspecting the distance between the top inclined surface of the side panel a and the middle pillar c.

[0035] As attached Figure 4 and attached Figure 5 As shown, the stopper 3 comprises a stopper plate 3.1, arranged parallel to the top slope of the side panel a, and support plates 3.2, located at both ends of the stopper plate 3.1. The stopper plate 3.1 is provided with a U-shaped groove 3.1.0, which allows for the installation of the inspection shaft 5. This design allows the inspection shaft to avoid interference from the stopper plate, allowing for inspection of the bracket while it is still mounted on the fixture without removing the bracket, thus reducing operational difficulty and improving work efficiency.

[0036] Preferably, as attached Figure 4 As shown, the shaft head and the overall length of the inspection shaft 5 are consistent with the shaft head and length of the standard roller. In this embodiment, the inspection shaft is used instead of the standard roller for inspection. Compared with the standard roller, the inspection shaft is light in weight and can effectively reduce the labor intensity of inspection. In addition, the inspection shaft can also be installed on the bracket during the bracket welding process, and can support and limit the side panels and the middle pillar to ensure the welding effect.

[0037] Preferably, as attached Figure 4 and attached Figure 5 As shown, the position-limiting member 3 of this embodiment further includes a connecting plate 3.3, the two ends of which are connected to the supporting plate 3.2, for increasing the structural strength of the position-limiting member. The bottom of the connecting plate 3.3 extends from the supporting plate 3.2 to support the crossbeam b. This design provides the crossbeam with multiple support points.

[0038] As attached Figure 4 To the attached Figure 7 As shown, the positioning member 4 comprises two positioning uprights 4.1, a connecting rib 4.2 connecting the two positioning uprights, and an L-shaped support block 4.3 located outside the positioning uprights for supporting the crossbeam b. The positioning uprights 4.1 serve as a formwork for the crossbeam b, and the support block 4.3 and the positioning uprights 4.1 form a crossbeam placement slot. This design allows the crossbeam to be placed simply by snapping it into the slot and aligning its ends with the side panels. Furthermore, the support block 4.3 is provided with a handle bolt 4.4 for clamping the crossbeam b. This handle bolt can be used to tighten the crossbeam, securing its position.

[0039] As attached Figure 4 and attached Figure 5 As shown, the fixing member 2 includes a positioning panel 2.1, two side support plates 2.2 and fixing bolts 2.3. The two ends of the positioning panel 2.1 are arranged in the top positioning grooves of the two side support plates 2.2, and the positioning panel 2.1 is provided with two screw holes 2.1.0 that match the mounting holes of the side panel a. The fixing bolts 2.3 are used to fix the side panel a on the positioning panel 2.1.

[0040] During specific implementation, fix the bottom of the side panel on the positioning panel of the fixing part. At this time, the inclined surface of the top of the side panel is limited and supported by the limiting plate of the limiting part; place the beam in the beam placement groove, adjust the position of the beam so that its two ends are docked with the side panel, and then tighten the handle bolt; place the middle pillar on the positioning vertical plate of the positioning part, spot weld the middle pillar and the beam, spot weld the side panel and the beam, and spot weld the stiffener between the side panel and the beam; install the inspection shaft for inspection, and after the inspection meets the requirements, fully weld all welds.

[0041] It is worth noting that after the bracket is assembled and before welding, a test shaft can be installed in place, with one end connected to the side panel and the other end connected to the center support. This will act as a limit support to ensure the welding effect. Similarly, a test shaft can also be installed between the center supports before welding.

[0042] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
