Description

TECHNICAL FIELD

[0001] The utility model relates to part testing device technical field, concretely relates to a part airtightness test water testing tool. BACKGROUND

[0002] In the mechanical manufacturing industry, some parts are often tested for air tightness. For some products, air tightness is a crucial indicator. Poor air tightness can cause leakage, which directly affects the reliability, economy and overall performance of the machine, leading to problems such as machine failure, abnormal operation, reduced efficiency, shortened lifespan, oil waste and environmental pollution in actual use. Therefore, leakage testing is very important in production. Air tightness testing usually involves injecting water or gas into the part, observing whether the part leaks water or gas after injection, and determining whether the part's air tightness meets the requirements. To improve the efficiency of part air tightness testing, a testing device is usually used to test the air tightness of the part.

[0003] For example, the patent document with publication number CN220120310U discloses a shell air tightness testing table, which includes a water tank, a water tank assembly, and a gas tank. The gas tank is connected to the water tank assembly through a pipeline. The water tank is connected to the water tank assembly through a pipeline. The water tank assembly includes a water tank, a water tank bottom plate, a side sealing plate, a water inlet pipe, and an air vent. The water tank is connected to the water tank through the water inlet pipe. The water tank bottom plate and the side sealing plate are provided with sealing materials on their surfaces. The air vent is in communication with the gas tank and is provided on the water tank bottom plate. This technical solution uses a workpiece pressing component to achieve multi-point vertical sealing columns, which can satisfy the simultaneous sealing of multiple assembly holes on the upper part of the shell and also serve to fix the shell.

[0004] Although the above technical solution can test the air tightness of parts, it requires a certain degree of sealing performance in the air tightness testing table itself to prevent water in the water tank from leaking out during testing, resulting in a complex structure of the testing table. In addition, the part to be tested needs to be placed in the tank body of the water tank during testing, which makes the placement and retrieval of the part, as well as the installation and fixation of the part, susceptible to the influence of the water tank side wall, reducing the convenience of part air tightness testing operations.

[0019] The following is further described in detail by specific embodiments:

[0020] The reference signs in the drawings of the specification include: fixed part 1, base 101, fixed rod 102, connecting plate 103, fixed plate 104, fixing piece 105, fixed groove 106, through hole 2, buffer 201, fixed hole 3, limiting block 4, part 5, water inlet 501.

[0021] As shown in the accompanying Figure 1 A part 5 leak test water test tool, including fixed part 1 and test part, fixed part 1 is used for fixing the position of the part 5 to be tested, and the test part is used for testing the leak of the part 5.

[0022] As shown in the accompanying Figure 2 The fixed part 1 includes a base 101, and the top of the base 101 is a test table, wherein the test table is a plane, and the test table is used for placing the part 5 to be tested. A plurality of fixed rods 102 are fixedly connected on the test table by bolts, the plurality of fixed rods 102 are distributed along the circumference of the test table, one end of the fixed rod 102 extends to the center of the test table, the other end of the fixed rod 102 extends away from the test table, and the fixed rod 102 is used for applying downward pressure to the circumference of the part 5, so that the part 5 can be stably placed on the test table.

[0023] A connecting plate 103 is arranged between the fixed rod 102 and the test table, the extension direction of the connecting plate 103 is consistent with the extension direction of the fixed rod 102, the top of the connecting plate 103 is connected with the fixed rod 102, the bottom of the connecting plate 103 is integrally formed with a fixed plate 104, the extension direction of the two ends of the fixed plate 104 is consistent with the extension direction of the connecting plate 103, and the two sides of the fixed plate 104 extend outward away from the connecting plate 103, that is, the fixed plate 104 and the connecting plate 103 integrally form a "⊥" shape. A plurality of fixing pieces 105 are arranged on the fixed plate 104, the plurality of fixing pieces 105 are uniformly distributed on the two sides of the connecting plate 103, and the fixing piece 105 is used for fixedly connecting the fixed plate 104 and the test table, wherein the fixing piece 105 can be a bolt or a rivet, and the fixed plate 104 and the test table are fixedly connected by bolts in the embodiment. The fixed rod 102 can be stably connected with the test table, so that the fixed rod 102 is not easy to shake during the test, the fixed effect of the fixed rod 102 on the part 5 is affected, and the part 5 is not easy to fall during the test due to unstable fixation, so as to avoid damage to the part 5.

[0024] The fixing rod 102 and the connecting plate 103 are rotatably connected via a rotating component. Both ends of the fixing rod 102 can rotate up and down along the height direction around the rotating component as an axis. The rotating component can be a pivot or a hinge. Preferably, in this embodiment, the fixing rod 102 and the connecting plate 103 are rotatably connected via a pivot. This allows the fixing rod 102 to apply pressure to or release the fixing of the part 5 by rotating it up and down along the height direction when fixing the part 5. This improves the ease of connection between the fixing rod 102 and the part 5, as well as the ease of disassembling and assembling the part 5 before and after testing. Furthermore, by rotating the fixing rod 102, when fixing parts 5 of different shapes, the fixing rod 102 can rotate to a height that matches the actual situation of the part 5, improving the compatibility between the testing fixture and parts 5 of different shapes.

[0025] A fixing groove 106 is provided at the corresponding position of the test platform and the fixing plate 104. The extending direction of the fixing groove 106 is consistent with the extending direction of the fixing plate 104. The fixing groove 106 is used to accommodate the fixing plate 104. This allows the fixing plate 104 to be positioned under the action of the fixing groove 106, preventing the fixing plate 104 from shifting its position under pressure over a long period of time, thus affecting the fixing effect of the fixing plate 104 on the fixing rod 102.

[0026] As attached Figure 3 As shown, a through hole 2 is provided at one end of the fixed rod 102 near the test platform, extending through the fixed rod 102 along its height. A buffer member 201 is inserted into the through hole 2, with one end of the buffer member 201 fixedly connected to the through hole 2 on the fixed rod 102, and the other end extending downward along its height. The diameter of the end of the buffer member 201 near the test platform is larger than the diameter of the end of the buffer member 201 inserted into the through hole 2. By providing the buffer member 201 on the fixed rod 102, when the fixed rod 102 contacts and fixes with the surface of the part 5, the contact area between the fixed rod 102 and the part 5 is increased under the action of the buffer member 201, improving the fixing effect while preventing the part 5 from directly contacting the fixed rod 102, thus avoiding friction between the part 5 and the fixed rod 102 during the test, which would cause wear on the surface of the part 5 and affect its quality.

[0027] The buffer 201 is made of soft elastic material, and specifically, the buffer 201 can be made of rubber, plastic or other soft elastic material. The buffer 201 can be closely attached to the part 5, improve the stability of the buffer 201 attached to the surface of the part 5, reduce the wear of the part 5 surface by the buffer 201, and ensure the safety of the part 5 during testing. In addition, the buffer 201 made of soft elastic material can also cover and block the holes on the surface of the part 5, reduce the steps of blocking the holes on the surface of the part 5, and improve the convenience of installing the part 5 on the test bench.

[0028] A fixing hole 3 is formed on one side of the test bench, and the fixing hole 3 is used for fixed connection with the part 5 through bolts or other fixing structures.

[0029] A limiting block 4 is further arranged on the side of the test bench away from the fixing hole 3, and the limiting block 4 is fixedly connected with the test bench through bolts. The limiting block 4 is used for limiting the position of the part 5 to be tested. The two sides of the part 5 can be limited in position under the action of the fixing hole 3 and the limiting block 4, further improving the stability of the part 5 installed on the test bench, and reducing the displacement of the part 5 during testing.

[0030] The test part includes a water injection pipe, one end of the water injection pipe is connected with the water inlet 501 of the part 5 to be tested, and the other end of the water injection pipe is in communication with the water delivery pipe. The water injection pipe is used for delivering water into the part 5 to be tested. The specific structure of the water injection pipe is a prior art, which will not be described here.

[0031] The specific implementation process is as follows:

[0032] When testing the airtightness of the part 5, the part 5 to be tested is placed on the test bench, and the part 5 is fixed on the test bench through the fixing rod 102. After the holes on the part 5 are blocked by the rubber pad or other blocking cover, the water injection pipe of the test part is connected with the water inlet 501 on the part 5, water is injected into the part 5 through the water injection pipe, the water seepage on the surface of the part 5 is observed, and the airtightness of the part 5 is determined.

[0033] Compared with the prior art, in the present scheme, when testing the airtightness of the part 5, the part 5 is fixed on the test bench, so that when the part 5 is installed and connected, the circumferential direction of the part 5 is in an unobstructed state, which facilitates direct operation of the part 5 during installation and testing, and improves the convenience of testing the airtightness of the part 5. In addition, the airtightness of the part 5 is tested by injecting water into the part 5, so that the overall structure of the test tool can be simplified, and the portability of the test tool is improved.

[0034] It should be pointed out that for those skilled in the art, without departing from the technical solutions of the present application, a number of variations and improvements can be made, which should also be considered as the protection scope of the present application, which will not affect the effect and practicality of the present application. The scope of protection claimed in this application shall be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
