Description

Technical Field

[0001] The utility model relates to the technical field of compressor processing tooling, and in particular to a tooling for processing diaphragm compressor parts. Background Art

[0002] With the advancement of welding technology, key components of diaphragm compressors are gradually manufactured by welding. Among them, the circular component, with a diameter of about 3m, is composed of multiple fan-shaped parts. Each fan-shaped part is welded by multiple ribs and connecting plates. Because the size of each workpiece is different, the position of each rib is irregular, manual measurement is difficult, and the inspection time is long. There is a certain height difference between the bottom surface of the rib plate and the bottom surface of the connecting plate. Due to the small size of the rib plate and the connecting plate, the welding volume is concentrated, the position and size requirements of the rib plate are strict, and manual measurement is limited in many positions. The measurement is not comprehensive, and it is impossible to fully measure to ensure the assembly size. It may cause the size to exceed the tolerance after welding, which will affect the subsequent use, resulting in the inability to install, affecting the product quality and subsequent on-site assembly. In addition, the special material of the rib plate and the connecting plate cannot be repaired and can only be scrapped, which will cause huge losses. In this case, the need for new processing tools is very urgent.

[0003] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0033] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings. Example

[0034] like Figure 1-6As shown together, the utility model provides a tool for processing diaphragm compressor parts, which is used for welding fan-shaped parts.

[0035] The plurality of positioning lines 7 are radially distributed from the same center point. Specifically, the plurality of positioning lines 7 are spaced apart from each other and arranged in a fan shape.

[0036] The tooling base plate 1 can be made of a plate and a workpiece placement plane 6 can be formed by machining.

[0037] A height positioning assembly is provided on the workpiece placement plane 6, which is used to support and position the height of the connecting plate 10 to ensure the height difference between the bottom surface of the rib plate 9 and the bottom surface of the connecting plate 10; the height positioning assembly includes a plurality of height determining blocks 2, and the plurality of height determining blocks 2 are arranged in sequence at intervals; the height determining blocks 2 and the positioning line 7 are staggered with each other to avoid interference.

[0038] Preferably, two height positioning assemblies are provided, and the two height positioning assemblies are spaced apart along the radial extension direction of the positioning line group.

[0039] The bottom surface of the height setting block 2 is connected to the tooling base plate 1, and the end surface of the height setting block 2 away from the tooling base plate 1 is the support positioning surface; the flatness of the support positioning surface is 0.1mm, and the parallelism between the support positioning surface and the workpiece placement plane 6 is 0.5mm.

[0040] Furthermore, the bottom surface and the supporting positioning surface of the height determining block 2 are both formed by machining.

[0041] When the rib plate 9 and the connecting plate 10 are paired, the bottom surface of the connecting plate 10 is completely in close contact with the supporting positioning surface of the height-fixing block 2, and the bottom surface of the rib plate 9 is completely in close contact with the workpiece placement plane 6, which can ensure the relative height of the connecting plate 10 and the rib plate 9 in the direction perpendicular to the workpiece placement plane 6, and ensure the flatness of the workpiece.

[0042] The tooling also includes a reinforcing tooling, which is used for assembly reinforcement during the welding stage after the rib plate 9 and the connecting plate 10 are assembled; the reinforcing tooling includes a reinforcing plate 3, which is pressed tightly on the assembled workpiece and is fastened to the tooling base plate 1 by connecting bolts.

[0043] The number of the reinforcing plates 3 is one or more, preferably two in this embodiment, and the two reinforcing plates 3 are arranged at intervals along the radial extension direction of the positioning line group to better realize the assembly reinforcement of the workpiece.

[0044] Furthermore, a first bolt hole 4 is provided on the tooling base plate 1, and a second bolt hole 8 corresponding to the first bolt hole 4 is provided on the reinforcing plate 3.
