Description

Technical Field

[0001] This utility model belongs to the field of sealing component testing technology, and specifically relates to a sealing component sealing performance testing device. Background Technology

[0002] In the field of industrial production and equipment manufacturing, seals are key components that ensure the sealing performance of equipment and prevent media leakage. Their sealing quality is directly related to the safe and stable operation of the equipment.

[0003] However, traditional sealing performance testing devices have significant drawbacks: First, the testing process is linear, and other operations cannot be carried out simultaneously during the steps of gas injection, pressure testing, result judgment, and removal of the sealing components. This results in a lengthy testing cycle, making it difficult to adapt to the high-speed operation of automated production lines and meet the batch testing needs of large-scale production scenarios. Second, after the test is completed, the sealing components must be manually removed one by one. Moreover, the sealing components are generally compatible with the placement slots, making them inconvenient to remove, which further leads to the low efficiency of the entire device. Therefore, a sealing performance testing device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a sealing performance testing device to solve the problems of not being able to carry out other operations simultaneously during the testing process and relying on manual removal of the sealing components one by one.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sealing component sealing performance testing device, comprising a collection box, wherein a rotating cylinder is rotatably disposed inside the collection box, and an air injection component is disposed directly above the rotating cylinder;

[0006] The rotating cylinder is provided with multiple transverse cavities, and multiple air injection cavities are provided inside the transverse cavities. Each air injection cavity is provided with several air injection inlet pipes and pressure detectors.

[0007] The air injection assembly includes a lifting plate, an air injection pipe, and an electric push rod. The air injection inlet pipe is partially made of a telescopic flexible hose. The top end of the air injection inlet pipe passes through a C-shaped frame and connects to the air injection device. The air injection inlet pipe is installed on the lifting plate.

[0008] Furthermore, a connecting shaft is provided laterally on the rotating cylinder, and both ends of the connecting shaft are rotatably connected to the collection box.

[0009] Furthermore, the air inlet pipe is T-shaped, and the groove at the top of the air inlet pipe is adapted to the shape of the seal to be tested.

[0010] Furthermore, the multiple sets of transverse cavities are located at the axis of the rotating cylinder and are rotationally symmetrical.

[0011] Furthermore, the gas injection assembly is mounted on a C-shaped frame, the bottom of which is connected to the top of the collection box.

[0012] Furthermore, the gas injection assembly also includes an electric push rod, which is mounted on a C-shaped frame, and the top of the lifting plate is mounted on the push shaft of the electric push rod.

[0013] Furthermore, a mounting base is provided on one side of the collection box, and a motor is mounted on the top of the mounting base. The output shaft of the motor is located near the side of the collection box, and a first gear is mounted on the output shaft of the motor. The first gear is meshed with a second gear, and the second gear is mounted on the connecting shaft of the rotating cylinder.

[0014] Furthermore, the ratio of the number of gears of the second gear to the number of gears of the first gear is the same as the number of transverse cavities.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This sealing performance testing device can effectively improve the working efficiency of the testing device by placing a sealing component in the groove of another set of air inlet pipes while gas is being injected into the first set of air injection cavities.

[0017] After the sealing performance testing device is completed, the sealing components will fall into the collection box under the action of gravity as the rotating drum rotates, which facilitates the collection and subsequent processing of the tested sealing components. This eliminates the need for manual removal of each component, effectively improving the convenience of the device. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments.

[0025] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0026] Please see Figure 1-5 This utility model provides a sealing performance testing device, including a collection box 10, a rotating cylinder 20 rotatably disposed inside the collection box 10, and an air injection component disposed directly above the rotating cylinder 20.

[0027] A connecting shaft 210 is horizontally arranged in the middle of the rotating cylinder 20, and both ends of the connecting shaft 210 are rotatably connected to the collection box 10. Six horizontal dividing plates 220 are horizontally arranged inside the rotating cylinder 20, dividing the interior of the rotating cylinder 20 into six horizontal cavities 201. The six horizontal dividing plates 220 are located on the connecting shaft 210 and are rotationally symmetrical. Multiple vertical dividing plates 230 are arranged inside the horizontal dividing plates 220, dividing the horizontal cavities 201 into multiple gas injection cavities 202. Several gas injection inlet pipes 240 and pressure detectors 250 are arranged on the rotating cylinder 20. The gas injection inlet pipes 240 and the pressure detectors 250 are respectively connected to a gas injection cavity 202. Gas is injected through the gas injection inlet pipes 240, causing the internal pressure of the gas injection cavity 202 to change. The gas is injected and then paused for a period of time. The pressure detectors 250 detect whether the internal pressure has changed.

[0028] The air intake pipe 240 is T-shaped, and the top groove of the air intake pipe 240 can hold a seal. The top groove of the air intake pipe 240 has the same shape.

[0029] The air injection assembly is installed on the C-shaped frame 110, the bottom of which is connected to the top of the collection box 10. The air injection assembly includes a lifting plate 310, an air injection pipe 320, and an electric push rod 330. The number of air injection pipes 320 is the same as the number of air injection inlet pipes 240 on a transverse cavity 201. The air injection inlet pipe 240 is partially made of a retractable hose. The top end of the air injection inlet pipe 240 passes through the C-shaped frame 110 and connects to the air injection device. The air injection inlet pipe 240 is installed on the lifting plate 310, and the electric push rod 330 is installed on the C-shaped frame 110. The top of the lifting plate 310 is installed on the push shaft of the electric push rod 330.

[0030] A mounting base 410 is provided on one side of the collection box 10. A motor 420 is mounted on the top of the mounting base 410. The output shaft of the motor 420 is located near the side of the collection box 10, and a first gear 421 is mounted on the output shaft of the motor 420. The first gear 421 is meshed with a second gear 422, and the second gear 422 is mounted on the connecting shaft 210 of the rotating cylinder 20.

[0031] Gear 422 and gear 421 are two gears of the same size but different numbers of gears. The ratio of the number of gears of gear 422 to gear 421 is the same as the number of transverse cavities 201. After gear 421 drives gear 422 to rotate, the rotation angle of the rotating cylinder 20 is the same as the angle of the two adjacent transverse cavities 201.

[0032] The working principle and usage process of this utility model are as follows: See Figure 5 The sealing element is placed in the groove of the upper left air inlet pipe 240. The motor 420 is started, which drives the first gear 421 to rotate. After the first gear 421 drives the second gear 422 to rotate, the rotating cylinder 20 rotates at the same angle as the two adjacent transverse cavities 201, so that the upper left air inlet pipe 240 rotates to the position directly below the air injection assembly. The electric push rod 330 is started to push the lifting plate 310 down, allowing the air injection pipe 320 to be inserted into the air inlet pipe 240, while simultaneously pressing the sealing element. Then, gas is injected into the air injection cavity 202 through the air injection device. While injecting gas, the sealing element can be placed in the groove of the upper left air inlet pipe 240 again, which can effectively improve the working efficiency of the detection device. After the gas injection is stopped, the pressure inside the air injection cavity 202 is detected by the pressure detector 250. If the sealing performance of the sealing element is poor, the pressure in the air injection cavity 202 will decrease faster, thereby detecting whether the sealing performance of the sealing element is qualified.

[0033] After the inspection is completed, the lifting plate 310 moves up to remove the unqualified seals. The rotating cylinder 20 continues to rotate to inspect the next side. As the rotating cylinder 20 rotates, the seals will fall into the collection box 10 under the action of gravity.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
