Description

Technical Field

[0001] This utility model relates to the field of automated conveying technology for ceramic bottles, and in particular to a venturi tube performance testing device. Background Technology

[0002] In the desorption system of a turbocharged engine, the venturi tube is a key component. Through the venturi effect, it converts the positive airflow generated by the turbocharger into negative pressure at the carbon canister end, driving fuel vapor into the combustion chamber to improve fuel efficiency and reduce HC emissions.

[0003] To ensure its desorption performance meets stringent environmental regulations, the manufacturing process requires a full inspection of the venturi tube, covering core parameters such as flow coefficient, vacuum level, and pressure-flow characteristics. However, existing testing technologies have significant shortcomings:

[0004] Firstly, the testing equipment is decentralized. Flow testing relies on independent wind tunnel equipment, differential pressure testing requires an external U-shaped pressure gauge, and vacuum calibration requires a dedicated negative pressure generator, which means that the testing process needs to be completed at multiple isolated workstations.

[0005] Secondly, the mobility and integration are insufficient. The separate equipment (such as air volume regulating valves, differential pressure gauges, and flow meters) are temporarily spliced ​​together through pipelines, occupying an area of ​​more than 2 square meters, which cannot meet the flexible scheduling needs of the production line, especially when switching between multiple detection points in the factory.

[0006] Therefore, there is an urgent need to develop an integrated testing platform that combines multi-parameter detection, is mobile and convenient, and automatically integrates data to improve the efficiency and accuracy of 100% inspection of Venturi tubes. Utility Model Content

[0033] Example 1

[0034] like Figures 1-7 As shown, this utility model provides a technical solution:

[0035] A venturi tube performance testing device includes, but is not limited to, a housing structure 1, a sliding stage 2, a fixing block 3, and a testing component 4. The housing structure 1 is provided with a support plate 11 for supporting the sliding stage 2. The fixing block 3 is detachably mounted on the sliding stage 2. Multiple fixing blocks 3 are configured according to different venturi tube models 5. The fixing block 3 is provided with a fixing groove for fixing the venturi tube 5. When the venturi tube 5 to be tested is fixed in the groove and the fixing block 3 is fixed on the sliding stage 2, the sliding stage 2 can slide and connect with the air inlet plug 42 of the testing component 4.

[0036] Based on the above structure, a detachable fixing block 3 is provided on the sliding stage 2, which can be fixed with different models of Venturi tubes 5 and tested. The fixing block 3 is provided with a fixing groove that matches the model of Venturi tube 5, such as "T" shape, "Y" shape, etc., so that it can be quickly assembled with the Venturi tube 5, realizing the testing of different models of Venturi tubes 5. After the fixing block 3 is fixed, the direction and position of the Venturi tube 5 are fixed. By sliding, it can be quickly docked with the air inlet plug 42 of the detection component 4, improving the detection efficiency.

[0037] As an example, the housing structure 1 may include a storage cavity 12 and a detection cover 13; the storage cavity 12 and the detection cover 13 are hinged by a hinge 14, and a hinge support is also provided between the storage cavity 12 and the detection cover; one end of the hinge support is hinged to the inner wall of the storage cavity 12, and the other end is hinged to the detection cover 13.

[0038] Based on the above structure, the hinge 14 can be used to connect the storage cavity 12 and the detection cover 13, which can facilitate the opening of the detection cover 13. At the same time, a hinge support is provided between the storage cavity 12 and the detection cover 13 to support the detection cover 13 when it is open and close it as needed, so that the testing can be carried out efficiently.

[0039] As an example, the hinge support may include a first hinge plate 15 and a second hinge plate 16. The contact portion of the first hinge plate 15 and the second hinge plate 16 is provided with an adjustment seat 17 for adjustable tightness. The adjustment seat 17 includes a rotating cover 171 and a threaded rod 172. A limiting disc 173 is provided at the end of the threaded rod 172 away from the rotating cover 171. The threaded rod 172 is hinged to the first hinge plate 15 and the second hinge plate 16 respectively, and the rotating cover 171 is sleeved on the threaded rod 172.

[0040] Based on the above structure, when the first hinge plate 15 and the second hinge plate 16 are fixed as needed, they are locked by rotating the rotating rod. At this time, the inspection of the Venturi tube 5 can be performed. When it is necessary to close the inspection cover 13, the locking state of the first hinge plate 15 and the second hinge plate 16 is released, allowing the inspection cover 13 to close smoothly.

[0041] As an example, a claw 18 may be provided on the outer wall of the storage cavity 12, and the claw 18 is symmetrically arranged along the center position of the storage cavity 12.

[0042] Based on the above structure, the claw lugs facilitate the movement of the housing structure 1. This solution integrates both the detection unit and the fixing unit into the housing structure 1, allowing for the detection of various key parameters of different venturi tubes 5 using a single device, greatly reducing the difficulty of subsequent testing.

[0043] As an example, the sliding stage 2 may include a support rail 21, a sliding block 22, a sliding plate 23, and a limiting plate 24; the support rail 21 is disposed on the support plate 11 inside the box structure 1; the sliding block 22 is disposed at the bottom position of the sliding plate 23, and the sliding block 22 is provided with a sliding groove structure that cooperates with the support rail 21, so that the sliding block 22 can move along the length direction of the support rail 21; the limiting plate 24 is disposed at the side position of the sliding plate 23, and the sliding plate 23 is provided with a limiting structure that cooperates with the limiting plate 24.

[0044] Based on the above structure, the sliding plate 23 can slide smoothly along the predetermined direction with the cooperation of the sliding block 22 and the support rail 21. At the same time, the limiting structure on the sliding plate 23 can cooperate with the limiting plate 24 to limit the extreme positions at both ends of the sliding plate 23, preventing the sliding platform from detaching from the support rail 21.

[0045] As an example, the sliding plate 23 is provided with a connection hole that mates with the fixing block 3. The fixing block 3 is detachably connected to the sliding platform by bolts to achieve the matching of different models of venturi tubes 5.

[0046] As an example, the limiting plate 24 is set perpendicular to the support plate 11. The end of the limiting plate 24 away from the support plate 11 is provided with a limiting groove 25. The limiting structure can be a limiting protrusion 26. The limiting protrusion 26 is set in the limiting groove 25. The limiting protrusion 26 can move along the length direction of the limiting groove 25 and is limited at both ends of the limiting groove 25.

[0047] Based on the above structure, by setting a limiting structure on the side of the sliding platform, the extreme positions at both ends of the sliding platform can be quickly restricted. At the extreme position at the end, the venturi tube 5 on it just contacts and cooperates with the air intake plug 42, so as to achieve rapid assembly.

[0048] As an example, the fixing block 3 may include a pipe fixing groove 31, a mating groove 32, and an assembly hole 33; the assembly hole 33 is provided through the fixing block 3, the pipe fixing groove 31 is provided across both ends of the fixing block 3, and the mating groove 32 is connected to the pipe fixing groove 31.

[0049] Based on the above structure, the fixing block 3 is connected to the sliding plate 23 at the bottom through the assembly hole 33, the venturi tube 5 is fixed in the tube body fixing groove 31, the negative pressure plug is inserted into the mating groove 32, and the key parameters of the venturi tube 5 are measured by the negative pressure plug.

[0050] As an example, the detection component 4 may include an air inlet pipe 41, a flow measurement pipe (not shown), a vacuum pressure measurement pipe (not shown), an air inlet plug 42, and an air outlet plug 43; the air inlet plug 42 is fixedly mounted on the support plate 11 at a predetermined position by a support, and the air outlet plug 43 is movably mounted on the support plate 11. The air inlet plug 42 is connected to the air inlet pipe 41, and the air outlet plug 43 is connected to the flow meter 44 and the vacuum pressure gauge 45 on the detection cover 13 through the flow measurement pipe and the vacuum pressure measurement pipe, respectively.

[0051] The intake pipe 41 is located on the outside of the housing structure 1. A pressure valve 46 is installed on the intake pipe 41. A regulating valve 47 and an emergency stop switch 48 for controlling the pressure valve 46 are installed on the support plate 11. The intake pipe 41 is also connected to the intake pressure gauge 49 on the detection cover 13 via a pipe.

[0052] Based on the above structure, this solution uses the intake pipe 41 to connect the venturi tube 5 to the intake plug 42 to achieve pressurization. The negative pressure plug is used to measure the negative pressure outlet of the venturi tube 5, measuring its flow rate and vacuum pressure value, thus achieving the measurement of key data of the venturi tube 5. The negative pressure plug can be moved to quickly match different venturi tubes 5. The measured data is displayed in real time by the vacuum pressure gauge 45 and the flow meter 44. The pressure gauge can be set to measure the pressure of the pipeline. The pressure regulating valve 47 and the emergency stop switch 48 can ensure pressure regulation and emergency on / off during use.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
