Description

Technical Field

[0001] The utility model relates to the technical field of rail transit vehicle body welding, in particular to an adjustable flexible tooling structure for welding. Background Art

[0002] In all the existing sites of the current main engine factories, there is no gasket adjustment for the tooling structure of high-speed train welding. The positioning accuracy of the tooling in the current main engine factories is generally above 3mm. The technology used is completed with a jig, which is also a small part in the field of automated welding. The current welding environment in the factory generally shows the effect of poor positioning positions. What makes up for this deficiency is manual labor. The workers have rich welding experience and can adjust to the required size through later repair welding and tools. With the development and progress of the times, the requirements for automated production in workshops have gradually increased, the accuracy of parts tooling has been improved, and the requirements for assembly line operations have increased the accuracy of single parts. In the past, the accuracy of tooling was generally controlled at more than 2mm, but if a new flexible tooling structure is used, we can now achieve within 0.5mm. The accuracy requirements in the future will continue to increase. This is a major trend in national development, so the current tooling cannot meet the current welding quality.

[0003] The original mold production or simple sample frame production can no longer meet the current requirements. Now the output is increasing, the number of models is increasing, and there is demand for self-use, subway, export, and production capacity. The original green body does not require much precision, and the mold just meets the requirements.

[0004] Therefore, we propose an adjustable flexible tooling structure for welding in order to solve the above-mentioned problems. Utility Model Content

[0014] Preferably, the inner wall of the locking hole is provided with an internal thread that cooperates with the positioning bolt, and the positioning bolt is screwed into the locking hole on the vertical support and the locking hole on the adjustment block to complete the fixation of the two.

[0015] By adopting the above technical solution, the internal thread of the locking hole can facilitate the screwing in of the positioning bolt.

[0016] Preferably, five adjusting gaskets are provided, and the adjusting gaskets are patches made of Q235 material.

[0032] The assembly of the tooling is completed by fixing the fixture base plate 1, the connecting base block 2, the adjusting block 4, the connecting block 7 and the part supporting bracket 9, so that the workpiece has the same position relationship each time it is placed on the tooling, thereby determining the position relationship in the Y and Z directions. At the same time, a part supporting bracket 9 is used for part support, so only the Y and Z directions need to be positioned.

[0033] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above-mentioned embodiment 1. When performing part support welding, it is not convenient to adjust the height of the tooling according to actual needs. Figure 1-Figure 3 As shown, this embodiment discloses the following technical contents: locking holes 5 are provided on both the vertical support 3 and the adjusting block 4, and the vertical support 3 is fixed to the adjusting block 4 by positioning bolts 6; there are multiple locking holes 5 evenly distributed on the vertical support 3, and the inner diameter of the locking holes 5 on the vertical support 3 is equal to the diameter of the locking holes 5 on the adjusting block 4. The inner wall of the locking hole 5 is provided with an internal thread that cooperates with the positioning bolt 6, and the positioning bolt 6 is screwed into the locking hole 5 on the vertical support 3 and the locking hole 5 on the adjusting block 4 to complete the fixation of the two.

[0034] Unscrew the positioning bolts 6 on the adjusting block 4 and the vertical support 3, then push the adjusting block 4 so that the locking holes 5 on the adjusting block 4 are aligned with the locking holes 5 at other positions on the vertical support 3. At this time, screw the positioning bolts 6 again so that the positioning bolts 6 are screwed into the locking holes 5 on the adjusting block 4 and the vertical support 3. In this way, the position of the adjusting block 4 after height adjustment can be fixed. The height of the part support bracket 9 can be changed by changing the height of the adjusting block 4.

There are five adjusting gaskets 8, and the adjusting gaskets 8 are patches made of Q235 material. The total height of the five adjusting gaskets 8 is 5mm, and the heights of the five adjusting gaskets 8 are 2mm, 1mm, 1mm, 0.5mm, and 0.5mm, respectively.

[0036] In actual processing, in order to ensure that the parts have the same positional relationship with the base plate in space every time, after the fixture is assembled, a three-coordinate measuring instrument is used to measure the top profile block. A set of 5mm adjustment gaskets 8 are used. The sizes of the 5 adjustment gaskets 8 are 2mm+1mm+1mm+0.5mm+0.5mm respectively. Different size deviations increase or decrease the height of the gasket. Within the deviation range allowed by the tooling design, the size of the part support is adjusted.
