Description

Technical Field

[0001] This utility model relates to the field of sealing detection technology, specifically a device for testing the sealing performance of rubber seals. Background Technology

[0002] Seals are materials or parts used to prevent fluid or solid particles from leaking between adjacent mating surfaces and to prevent external impurities such as dust and moisture from entering the interior of machinery and equipment. They are typically annular in shape. In modern industrial manufacturing, seals are critical components, and their sealing performance is essential for ensuring the normal operation of the entire equipment. To ensure that seals meet the expected sealing effect after production, sealing performance testing has become an indispensable process. Currently, various seal testing devices are available on the market, aiming to improve testing efficiency and accuracy.

[0003] Utility model patent application CN222514438U discloses a rubber seal sealing performance testing device, comprising a housing, a circular base, a controller, and further comprising: an electric push rod, which is fixedly connected to the top surface of the housing by a bracket, and a pressure block is fixedly installed at the telescopic end of the electric push rod; a testing mechanism, which is disposed on the circular base; wherein, the testing mechanism includes a water storage tank, which is arranged in a ring on the circular base, and a support part is provided inside the water storage tank; a water reservoir is provided at the center of the circular base, and a through groove for connecting the water storage tank and the water reservoir is provided on the top surface of the circular base; an air supply part is provided at the lower end of the circular base; and a drive part is provided inside the housing.

[0004] As shown in the above utility model, existing rubber seal sealing performance testing devices allow operators to conveniently place and remove seals from other support blocks while testing one seal, thereby improving testing efficiency. However, although the circular base of the existing rubber seal sealing performance testing device can hold multiple seals, the support structure is relatively fixed, resulting in poor adaptability to different models and sizes of rubber seals. This may prevent the accurate placement and testing of some special-specification seals, thus limiting the applicability of the testing device. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides two technical solutions:

[0029] First embodiment: A rubber seal sealing performance testing device includes a testing box 1, a driving mechanism 2, an adsorption mechanism 3, a pressing component 4, and a placement component 5. The testing box 1 is used to store the testing liquid and to perform sealing performance testing on the rubber seal. A mounting plate 11 is fixed at the top center of the testing box 1, and a drain valve 12 is fixed at the bottom center of the testing box 1 to drain the testing liquid in the testing box 1 after the test is completed.

[0030] Specifically, the drive mechanism 2 is installed on the top of the test box 1 and is used to drive the clamping mechanism to clamp the rubber seal. The drive mechanism 2 includes a telescopic cylinder 21 fixed in the middle of the upper surface of the mounting plate 11. The output shaft of the telescopic cylinder 21 is fixed with a connecting column 22. Multiple support plates 23 arranged in a ring array are fixed on the lower periphery of the connecting column 22. The ends of the support plates 23 are connected to the clamping member 4. The upper surface of the support plates 23 is connected to the connecting column 22 through a reinforcing plate 24 to improve the support strength of the support plates 23.

[0031] Specifically, the adsorption mechanism 3 is installed on the top of the detection box 1 and is used to draw through the channel sealed by the rubber seal through the adsorption element to detect the sealing performance of the rubber seal. The adsorption mechanism 3 includes a vacuum pump 31 fixed on the upper surface of the mounting plate 11. The output end of the vacuum pump 31 is connected to a collection box 32. An annular diverter pipe 33 is fixed in the middle of the lower surface of the mounting plate 11. The output end of the annular diverter pipe 33 is connected to the vacuum pump 31. The input end of the annular diverter pipe 33 is connected to multiple connecting pipes 34 arranged in an annular array. The connection between the annular diverter pipe 33 and the connecting pipes 34 is connected by a miniature solenoid valve. The end of the connecting pipe 34 is connected to the clamping element 4.

[0032] More specifically, the clamping component 4 is located inside the detection box 1. The clamping component 4 is connected to the output end of the drive mechanism 2 and the input end of the adsorption mechanism 3 respectively. The clamping component 4 includes multiple pressure plates 41 located on the edge of the inner cavity of the detection box 1. An annular convex plate 42 is fixed on the lower surface of the pressure plate 41. A mating groove 43 is opened in the middle of the lower surface of the pressure plate 41. Multiple air inlet grooves, i.e. air inlet holes 44, are opened on the annular convex plate 42. A collecting groove with an annular groove structure is opened at the bottom of the groove of the air inlet hole 44. The collecting groove is connected to the connecting pipe 34.

[0033] The second embodiment differs from the first embodiment in that: the placement component 5 is installed at the bottom of the inner cavity of the test chamber 1 and is used to place the rubber seal. The placement component 5 includes a placement plate 51 located below the pressing component 4. The lower surface edge of the placement plate 51 is connected to the inner bottom wall of the test chamber 1 through a plurality of support columns 52 arranged in a ring array. A positioning column 53 is fixed in the middle of the upper surface of the placement plate 51. The positioning column 53 corresponds to the mating groove 43. A placement groove 54 is opened on the upper surface edge of the placement plate 51. The placement groove 54 is used to place the rubber seal. The placement groove 54 corresponds to the annular convex plate 42. A plurality of through holes 55 arranged in a ring array are opened at the bottom of the placement groove 54. The positioning column 53 and the mating groove 43 are used for positioning the pressing plate 41 and the placement plate 51, so that the annular convex plate 42 can be accurately moved into the placement groove 54.

[0034] When this device is in operation, the rubber seal to be tested is first placed into the placement groove 54 on the placement plate 51. Different placement plates 51 in the testing box 1 can hold rubber seals of different sizes. When placing the rubber seal, a suitable placement groove 54 is selected. Then, the telescopic cylinder 21 is activated. The telescopic cylinder 21 drives the pressure plate 41 to move downward through the connecting column 22 and the support plate 23 until the annular convex plate 42 on the pressure plate 41 contacts the rubber seal. At this time, the rubber seal seals the air inlet 44 on the annular convex plate 42. The through hole 55 in the placement groove 54 is also blocked. Then, the test liquid is injected into the test box 1 until the liquid overflows the lower surface of the placement plate 51. Then, the vacuum pump 31 is started. The vacuum pump 31 evacuates the collecting groove in the pressure plate 41 through the annular diverter pipe 33 and the connecting pipe 34, creating a negative pressure in the collecting groove. If the sealing performance of the rubber seal is not good, the test liquid in the test box 1 will be drawn into the collecting groove and finally flow into the collection box 32. If the sealing performance of the rubber seal is good, the test liquid will not flow into the collection box 32.
