[0023] Embodiment 1:

[0024] The preferred embodiment of the performance test tooling for stainless steel flanges provided by the present utility model is as Figures 1 to 4 shown: A performance test tooling for stainless steel flanges includes a test bench 1, a support frame 2 is fixedly installed at the bottom end of the test bench 1, and a limiting mechanism 3 is arranged on the test bench 1;

[0025] The limiting mechanism 3 includes an electric push rod 301, a fixing plate 302 is fixedly installed at the output end of the electric push rod 301, a limiting arc plate 303 is fixedly installed at the top end of the fixing plate 302, a limiting arc groove 304 is opened on the test bench 1, the limiting arc plate 303 movably penetrates through the limiting arc groove 304, a baffle 305 is arranged at the top end of the limiting arc plate 303, a connecting shaft 306 is fixedly installed at the top end of the limiting arc plate 303, one end of the baffle 305 is rotatably sleeved on the outer wall of the connecting shaft 306 through a bearing, and a magnetic plate 307 is fixedly installed at the bottom end of the baffle 305.

[0026] Specifically in the above technical solution, first, the electric push rod 301 is started. The electric push rod 301 drives the fixed plate 302 to move upward, and the fixed plate 302 drives the limit arc plate 303 to move upward. A group of limit arc plates 303 corresponding to the center hole of the stainless steel flange to be tested can be extended out of the limit arc groove 304. Then, the stainless steel flange to be tested can be placed at the center of the test bench 1, so that the hollow hole of the stainless steel flange is sleeved outside the limit arc plate 303, and the limit arc plate 303 limits the stainless steel flange on the test bench 1. At this time, the baffle 305 can be rotated to make the baffle 305 snap onto the top surface of the stainless steel flange, so that the magnetic plate 307 is magnetically connected to the stainless steel flange, thus completing the limit fixation of the stainless steel flange on the test bench 1. Through this mechanism, stainless steel flanges of different specifications can be limited and fixed on the test bench 1, and the stability is relatively high, solving the problem that the existing test fixture for stainless steel flanges can usually only stably limit and fix stainless steel flanges of one specification, and the stability is poor when limiting and fixing stainless steel flanges of different specifications, thus affecting the normal test of stainless steel flanges.

[0027] Further, the number of the limit arc plates 303 and the limit arc grooves 304 is four, and the four limit arc plates 303 and the limit arc grooves 304 form a group. Multiple groups of limit arc plates 303 and limit arc grooves 304 can be arranged on the fixed plate 302 and the test bench 1, and the diameters of the multiple groups of limit arc plates 303 and limit arc grooves 304 increase sequentially from inside to outside.

[0028] Among them, by arranging the limit arc plate 303, the stainless steel flange can be limited.

[0029] Further, the number of the connecting shafts 306 and the baffles 305 on the limit arc plate 303 is two, and the limit arc plate 303 is adapted to the limit arc groove 304.

[0030] Among them, by arranging the baffle 305, the stainless steel flange can be longitudinally limited.

[0031] Embodiment 2:

[0032] On the basis of Embodiment 1, a preferred embodiment of the performance test fixture for stainless steel flanges provided by the present utility model is as Figures 1 to 4 shown: A cavity 4 is formed inside the test bench 1. An adsorption hole 5 is formed in communication between the top end of the test bench 1 and the cavity 4. A vacuum pump 8 is fixedly installed on the outer wall of the test bench 1. The output end of the vacuum pump 8 is communicated with a vacuum tube 7, and the vacuum tube 7 fixedly penetrates the outer wall of the test bench 1 and is communicated with the cavity 4.

[0033] Specifically in the above technical solution, when the stainless-steel flange is placed on the test bench 1, the vacuum pump 8 is started, and the vacuum pump 8 performs a vacuum suction operation on the cavity 4. At this time, the stainless-steel flange will be firmly adsorbed on the test bench 1 through the adsorption holes 5, further improving the stability of the stainless-steel flange on the test bench 1 during testing, ensuring the test accuracy, with a simple structure and strong practicability.

[0034] Furthermore, the number of the adsorption holes 5 is several, and an adsorption head 6 is inserted at the top of the adsorption hole 5;

[0035] Among them, by setting the adsorption head 6, the sealing performance between the stainless-steel flange and the adsorption hole 5 can be improved.

[0036] Furthermore, the material of the adsorption head 6 is wear-resistant rubber.

[0037] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
