DETAILED DESCRIPTION

[0024] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings of the specification.

[0025] As shown in Figures 1-4 A waterway air tightness test tool, comprising a fixed plate 10, the top of the fixed plate 10 is fixedly connected with positioning block 20 and support block 30 for workpiece positioning, the top of the fixed plate 10 is fixedly connected with fixed unit 40 for workpiece fixing at four corners, and the top of the fixed plate 10 is fixedly connected with air tightness test unit 50 on one side;

[0026] The air tightness test unit 50 comprises a pushing piece 52, the output end of the pushing piece 52 is fixedly connected with a fixed frame 53, and the first end of the fixed frame 53 is fixedly connected with a water nozzle 54. The positioning block 20 and the support block 30 are used for positioning and supporting the test workpiece, ensuring the accuracy of the test; the fixed unit 40 is used for firmly fixing the test workpiece on the fixed plate 10, preventing the test workpiece from moving or shaking during the test; and the air tightness test unit 50 pushes the fixed frame 53 to move horizontally through the pushing piece 52, so that the water nozzle 54 is in sealing cooperation with the test workpiece, thereby realizing the air tightness test of the waterway system.

[0027] The outlet of the water nozzle 54 is provided with a step structure for sealing cooperation with the workpiece, which can enhance the sealing performance between the water nozzle 54 and the workpiece and effectively prevent gas leakage during the test.

[0028] In some embodiments, the pushing piece 52 is a pneumatic cylinder, and the bottom of the pneumatic cylinder is fixedly connected to the top of the fixed plate 10 through a first mounting plate 51. The pneumatic cylinder drives the fixed frame 53 to move horizontally, so that the water nozzle 54 is in rapid sealing cooperation with the test workpiece.

[0029] In some embodiments, the pushing piece 52 is a manual clamp used to push the fixed frame 53 to move horizontally. By manually operating the manual clamp, the horizontal movement of the fixed frame 53 can be manually controlled, so as to realize the sealing fit of the water nozzle 54 with the test workpiece.

[0030] In some embodiments, the air tightness test unit 50 further comprises a second mounting plate 56, the top of which is fixedly connected with a guide rail, and the bottom of the fixed frame 53 is fixedly connected with a sliding block 55 which is slidingly connected to the guide rail, thereby improving the precise guidance and stable sliding of the fixed frame 53 and avoiding test errors caused by movement deviation.

[0031] The fixed unit 40 comprises a support 41, the top of which is fixedly connected with a mounting frame 42, the top of which is fixedly connected with a mounting frame 42, one side of the top of which is rotatably connected with a support plate 43, and the other side of the top of which is rotatably connected with a rotating piece 45; the side of the support plate 43 away from the mounting frame 42 is rotatably connected with a pressing piece 44, the leading end of which is rotatably connected to the rotating piece 45; the side of the rotating piece 45 away from the mounting frame 42 is fixedly connected with a pressing rod 47 through a fixing piece 46. By pressing the tail end of the pressing piece 44 downward, the bottom end of the pressing rod 47 is driven by the rotating piece 45 to move downward, thereby fixing the test workpiece. The uniform pressing force of the multiple fixed units 40 on the test workpiece prevents the movement or shaking of the workpiece during the test.

[0032] The bottom end of the pressing rod 47 is fixedly connected with a pressing pad 48, which has a soft material and hardness that not only ensures the uniform distribution of the pressing force on the workpiece, but also avoids damage to the workpiece caused by excessive pressing force.

[0033] The tail end of the pressing piece 44 is sleeved with a handle 49, the surface of which is provided with anti-slip patterns, so that the test personnel can hold and operate the pressing piece 44 more easily through the handle 49, thereby improving the work efficiency.

[0034] The bottom of the fixed plate 10 is fixedly connected with a foot pad 60 at each corner. The foot pad 60 provides stable support and anti-slip function for the tooling, and has a certain softness, which can effectively absorb the vibration and impact during the test, thereby ensuring the stability of the tooling and further ensuring the accuracy of the test results.

[0035] In use, the workpiece to be tested is placed on top of the fixed plate 10. The workpiece is supported and positioned by the positioning block 20 and the support block 30. The tail end of the pressing part 44 is pressed down, and the bottom end of the pressure rod 47 is moved downward by the rotating part 45. The pressure pad 48 is pressed and fixed on the surface of the workpiece. The fixed frame 53 is pushed horizontally by the pushing part 52, so that the water nozzle 54 is sealed with the workpiece to achieve the airtightness test of the water system.
