Description

Technical Field

[0001] This utility model belongs to the technical field of airtightness testing equipment, specifically relating to an airtightness testing sealing floating compensator. Background Technology

[0002] The vehicle's thermal management system is a collection of components used to regulate the operating temperature of parts and the temperature environment of the passenger compartment. As the architecture of thermal management systems becomes increasingly complex, the number of components also increases. To improve the assembly efficiency of thermal management systems, flow channels in flow plates are often used instead of internal pipes in the thermal management system to reduce the assembly difficulty.

[0003] The existing flow channel plate is made of plastic and requires welding. During welding, the flow channel plate will deform, and the direction and amount of deformation cannot be accurately controlled. This makes it impossible for the original detection equipment to effectively seal the various cavities and nozzles of the flow channel plate. Based on this, our company has developed a gas detection sealing floating compensator to replace the existing technology. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a floating compensation device for airtightness testing to solve the technical problem that the testing equipment cannot compensate for the deformation of the flow channel plate during the airtightness testing of the flow channel plate.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a gas detection sealing floating compensator, characterized in that: a first fixing member and a connecting body fixed to the upper part of the first fixing member by bolts, a second fixing member and a third fixing member are connected by bolts, a receiving groove is formed between the second fixing member and the third fixing member, the connecting body is inserted into the receiving groove, a through hole is opened in the axis of the second fixing member, the axis of the connecting body is coaxial with the axis of the through hole, a sealing groove corresponding to the through hole is opened on the connecting body, a wave spring is installed in the sealing groove, and a wave ball is fixedly connected to the upper part of the wave spring.

[0006] Furthermore: the connecting ring extends the outer ring of the connecting body to divide the receiving groove into a first adjustment groove and a second adjustment groove, and a ball bearing tray is placed in the first adjustment groove and the second adjustment groove, and a seal is installed on the ball bearing tray.

[0007] Furthermore: the second fastener has a boss on its inner wall, and the third fastener is divided into two levels by a step. The upper level of the third fastener is bolted to the second fastener, and the connecting ring slides up and down along the boss and the step.

[0008] Compared with the prior art, this utility model has the following advantages: By combining the wave spring and the ball bearing, the wave spring 8 is compressed after contacting the ball bearing 9 at the flow channel outlet, compensating for defects in the flow channel outlet itself or defects caused by the deformation of the flow channel plate. On the other hand, the second fixing member 3 drives the third fixing member 4 to slide along the connecting ring 11 with the deformation of the flow channel plate, compensating for the deformation of the flow channel plate. It has good applicability and scalability. Attached Figure Description

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0012] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] In the first embodiment of this utility model, as Figure 1 As shown, a gas detection sealing floating compensator is characterized by: a first fixing member 1 and a connecting body 2 fixed to the upper part of the first fixing member 1 by bolts; a second fixing member 3 and a third fixing member 4 are connected by bolts; a receiving groove 5 is formed between the second fixing member 3 and the third fixing member 4; the connecting body 2 is inserted into the receiving groove 5; a through hole 6 is opened in the axis of the second fixing member 3; the axis of the connecting body 2 is coaxial with the axis of the through hole 6; a sealing groove 7 corresponding to the through hole 6 is opened on the connecting body 2; a wave spring 8 is installed in the sealing groove 7; and a wave ball 9 is fixedly connected to the upper part of the wave spring 8.

[0014] In the above technical solution: the first fixing member 1 is an annular ring used to connect the flow channel plate airtightness testing fixture. Since the flow channel plate airtightness testing fixture is not related to the technical effect of this solution, it will not be described. The axis of the connecting body 2 is coaxial with the first fixing member 1. The structure of the second fixing member 3 is L-shaped, with one long side and one short side. The long side is connected to the flow channel plate to be tested by bolts. The structure of the third fixing member 4 is a stepped ring. The upper ring of the third fixing member 4 is connected to the short side of the second fixing member 3 by bolts. An open receiving groove 5 is formed between the second fixing member 3 and the third fixing member 4. The connecting body 2 is inserted into the receiving groove 5, and the connecting body 2 is larger than the through hole 6. At the same time, an opening is made between the connecting body 2 and the through hole 6. The sealing groove 7 is coaxial with the perforation 6, and the sealing groove 7 is larger than the perforation. The sealing groove 7 is equipped with a wave spring 8. The lower part of the wave spring 8 is fixedly connected to the sealing groove 7, and the upper part is fixedly connected to the wave ball 9. The wave ball 9 is larger than the perforation 6. The flow channel plate airtightness detection fixture drives the device to descend so that the perforation 6 of this scheme connects with the flow channel outlet of the flow channel plate. After the flow channel outlet contacts the wave ball 9, the wave spring 8 is compressed to compensate for the defects of the flow channel outlet itself or the defects of the flow channel plate. Since the flow channel plate is inflated after sealing, it will cause the flow channel plate itself to deform. The deformation of the flow channel plate will cause the contact between the flow channel outlet and the wave ball 9 to be separated. At this time, the potential energy of the compressed wave spring 8 rebounds to ensure the contact between the wave ball 9 and the flow channel outlet and ensures the seal.

[0015] The outer ring of the connecting body 2 extends the connecting ring 11 to divide the receiving groove 5 into a first adjustment groove 12 and a second adjustment groove 13. A ball bearing tray 14 is placed in the first adjustment groove 12 and the second adjustment groove 13, and a seal 15 is installed on the ball bearing tray 14.

[0016] The second fixing member 3 has a boss 16 on its inner wall. The third fixing member 4 is divided into two levels by a step 17. The upper level of the third fixing member 4 is bolted to the second fixing member 3. The connecting ring 11 slides up and down along the boss 16 and the step 17.

[0017] In the above technical solution: the outer ring of the connecting body 2 is located in the receiving groove 5 and extends to the connecting ring 11. The connecting ring 11 does not contact the short side of the second fixing member 3. Its length is in contact with the inner wall of the boss 16 of the second fixing member 3 and the step 17 of the third fixing member 4 near the connecting body 2. The upper part of the connecting ring 11 has a ball bearing tray 14 facing the lower side wall of the long side of the second fixing member 3. There are balls 15 on the ball bearing tray 14.

[0018] The lower part of the connecting ring 11 has a ball bearing tray 14 facing the upper side wall of the lower part of the third fixing member 4. There are balls 15 on the ball bearing tray 14. Since the flow channel plate will deform itself when it is inflated after sealing, a second fixing member 3 and a third fixing member 4 are used to achieve rotation and sliding compensation in the connecting body 2. After the flow channel plate is inflated and deformed, the second fixing member 3 drives the third fixing member 4 to slide along the connecting ring 11 with the deformation of the flow channel plate to compensate for the deformation of the flow channel plate.

[0019] The above are merely preferred embodiments of the present utility model. It should be noted that, for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the scope of protection of the present utility model.
