Problems solved by technology
However, when the thickness of the flange to be tested is not uniform (the contact surface of the flange to be tested and the pressure plate is an inclined plane), or when the pressure plate is deformed due to force, the pressure plate cannot be closely attached to the surface of the test method. Will damage the surface of the flange to be tested

Embodiment Construction
[0017] Such as Figure 1 to Figure 3 As shown, a flange connection device includes a tooling flange 1 and a flange 2 to be tested. There are four compression bolts 3 distributed on the tooling flange 1 in a circle, which can also be set according to the actual situation. A plurality of compression bolts 3, the tooling flange 1 is connected with a pressure plate 4 through the compression bolts 3; the compression bolts 3 are installed in the through holes opened on the pressure plate 4; the pressure end 4.1 of the pressure plate 4 is provided on the lower surface A hemispherical pressing protrusion 5; a cushion block 6 matching the pressing protrusion 5 is placed on the flange plate 2 to be tested; Groove, the pressing protrusion 5 abuts against the cushion block 6 through the arc groove. The pressing plate 4 presses the flange 2 to be tested on the flange 1 of the tooling through the pressing protrusion 5 and the spacer 6 .
[0018] The tooling flange 1 is also provided with ...

The invention discloses a flange connection device which comprises a tool flange, wherein the tool flange is connected with a pressure plate through a hold-down bolt; a hemispherical compaction bulgeis arranged on the lower surface of the compaction end of the pressure plate; the compaction bulge is abutted against a cushion block matched with the compaction bulge; the pressure plate compacts a to-be-tested flange on the tool flange through the compaction bulge and the cushion block. Since the cushion block is placed on the to-be-tested flange and tightly fits the to-be-tested flange, the compaction bulge can press the cushion block from a plurality of angles so as to compact the to-be-tested flange on the tool flange. While the tool flange can cooperate with various to-be-tested flanges,the pressure plate can be prevented from damaging the flanges, and thus the quality of the to-be-tested flanges is guaranteed.
Description
technical field [0001] The invention relates to the field of flange plate assembly; in particular, it relates to a flange plate connecting device. Background technique [0002] In the power transmission device, bolts are usually used to connect two flanges to realize torque transmission. The power transmission device needs to be tested before leaving the factory. Since the bolt specifications, quantity and distribution positions of the flanges of various products are different, it is necessary to make a tooling flange that matches the flange to be tested before the test. When there are many types of products, it is necessary to manufacture multiple tooling flanges for matching, the cost is high, and the management and maintenance of tooling are difficult; and when testing different types of flanges to be tested, different tooling methods need to be replaced Blue plate, the work efficiency is low. [0003] In order to solve the above problems, in the prior art, a pressure p...
