[0029] Compared with the traditional method that requires designing a tooling fixture for almost every component to be inspected, by adjusting the position of the positioning assembly in the horizontal and vertical planes, the positioning space can adapt to the clamping and fixing position, shape and size requirements of components to be inspected with various structures and sizes. It has strong versatility and can meet the positioning and fixing requirements of various air-conditioning components, thereby providing a universal special inspection tooling for the inspection operation, facilitating inspection and improving inspection efficiency; mechanized operation and high positioning and installation efficiency further improve the inspection efficiency.

[0030] As an optional implementation, the positioning assembly includes a suspension mechanism 1 and a support portion; the horizontal adjustment assembly 32 is transmission-connected to the suspension mechanism 1 and can drive the suspension mechanism 1 to move in the horizontal direction; the vertical adjustment assembly 31 is installed on the suspension mechanism 1 and transmission-connected thereto; the suspension mechanism 1 alone or in cooperation with the support portion realizes the positioning and fixation of the air-conditioning component to be inspected.

[0033] The suspension beam 2 slides up and down along the suspension bracket 11 driven by the vertical adjustment component 31, and the suspension bracket 11 can move in the horizontal direction driven by the horizontal adjustment component 32, thereby adjusting the positioning space formed between the suspension beam 2 and the support part, so that the shape and / or size of the positioning space changes; or when the suspension beam 2 slides up and down, it drives the component to be detected installed thereon to move up and down to adjust the height of the component to be detected.

[0035] In order to suspend the component to be inspected, a fixed block 20 is retractably installed in the suspension beam 2. When inspecting the pipeline component, the fixed block 20 is extended out of the suspension beam 2 to suspend the component to be inspected; when the support part and the suspension beam 2 are needed to jointly support and position the component to be inspected (such as a heat exchanger assembly), the fixed block 20 is retracted into the suspension beam 2 to prevent the fixed block 20 from hitting the component to be inspected and causing damage.

[0036] As an optional implementation, the suspension beam 2 includes a hollow beam, a lifting joint 22 and a crankshaft 23. A plurality of telescopic holes are opened on the upper side of the hollow beam. The crankshaft 23 is arranged in the hollow cavity of the hollow beam. The first end 221 of the lifting joint 22 is pivotally connected to the crankshaft 23. The second end 222 of the lifting joint 22 is connected to the fixed block 20 through the telescopic hole. The rotation of the crankshaft 23 drives the lifting joint 22 and then drives the fixed block 20 to rise and fall.

[0037] like Figure 4 As shown, the pivot 25 is located on one side of the crankshaft 23. When the crankshaft 23 rotates, the pivot 25 revolves accordingly, and the lifting joint 22 pivotally connected thereto moves up and down accordingly; the fixed block 20 installed on the lifting joint 22 also moves up and down.

[0039] The two guide wings of the guide portion 26 limit and guide the lifting joint 22, so that the lifting and lowering of the lifting joint 22 is more reliable.

[0040] As an optional implementation, the fixing block 20 is detachably mounted on the lifting joint 22, and different fixing blocks 20 can be replaced according to the type of the component to be detected to meet the positioning requirements.

[0044] As an optional implementation, the fixing block 20 includes a connecting portion 202 and a mounting portion 201 that are fixedly connected to each other.

[0045] The fixing block 20 is connected to the lifting joint 22 via the connecting portion 202 , and the component to be detected is arranged on the mounting portion 201 for detection.

[0046] As an optional implementation, the mounting portion 201 of the pipe joint module has a mounting groove 2011 , and a top column 2012 is disposed in the mounting groove 2011 .

[0047] As an optional implementation, the mounting portion 201 of the flat head module has a mounting groove 2011 .

[0048] As an optional implementation, the installation groove 2011 is a step-type structure, consisting of a plurality of step grooves.

[0049] By adopting the differential structure, components to be inspected of different sizes (such as different pipe diameters) can be reliably installed and positioned.

[0050] As an optional implementation, the mounting portion 201 of the pointed module is a cone, and the connecting portion 202 is located at the bottom surface of the cone.

[0051] As an optional implementation, the suspension beam 2 is a supporting movable rod, and the supporting movable rod is used to position and fix the component to be detected together with the supporting part.

[0052] The height of the supporting moving rod can be adjusted according to the size of the component to be detected.

[0053] As an optional implementation, the suspension bracket 11 includes a guide rail 111 , and the suspension beam 2 can be slidably disposed on the guide rail 111 .

[0054] The suspension bracket 11 includes a guide rail 111 , and the suspension beam 2 is slidably disposed on the guide rail 111 . The suspension beam 2 slides in a vertical direction along the guide rail 111 .

[0055] As an optional implementation, a scale 112 is provided on the guide rail 111, which can be used to locate the height of the suspension beam 2 with higher accuracy.

[0056] As an optional implementation, the supporting portion is a stepped base or a U-shaped base 42 , and the stepped surface of the stepped base faces the suspension mechanism 1 .

[0057] The stepped base is suitable for situations where the bottom height of the component to be tested is inconsistent. When placed, all parts are supported, which is more reliable. The U-shaped base 42 is used to protect and support the heat exchanger to be tested. The U-shaped heat exchange tube can be embedded in the U-shaped groove and is not easily damaged by bumps.

[0058] The step-shaped base and the U-shaped base 42 are both made of rubber material to play a role of buffering and protection.

[0059] As an optional implementation, the adjustment mechanism is a screw rod 313 adjustment mechanism, which makes the adjustment more stable and the suspension mechanism 1 moves more smoothly.

[0060] like Figure 1 As shown, a detection auxiliary positioning device for air-conditioning components provided in a specific embodiment of the present invention includes an adjustment mechanism, a suspension mechanism 1 and a support portion.

[0061] like Figure 8 As shown, the ball screw as an adjustment mechanism mainly includes a screw handle 311, a screw, a coupling 312 and a support seat. During use, the mechanism is mainly used for position adjustment of the suspension mechanism 1 to achieve the purpose of rapid switching and accurate positioning. As the position adjustment screw of the horizontal adjustment component 32, the suspension mechanism 1 can be adjusted along the axial direction of the screw, especially during the inspection of the heat exchanger component, the front and rear position can be adjusted according to the size of the component to ensure that the component to be inspected meets the inspection position requirements. In the figure, the upper and lower position adjustment screws of the vertical adjustment component 31 are used to adjust the height of the fixed suspension beam 2 during the inspection process to meet the inspection requirements of different structural parts.

[0062] The material suspension system as the suspension mechanism 1 is mainly used for the suspension detection of different types of pipeline components. The system mainly includes a suspension beam 2 and a suspension bracket 11. In this embodiment, the number of the suspension mechanism 1 is two sets, one of which is a telescopic structure. Figure 4 , including a hollow beam, a crankshaft 23, a lifting joint 22, a fixed block 20 and an adjustment handle. The structural principle of the crankshaft 23 is utilized, and the lifting joint 22 is lifted and lowered by adjusting the handle, thereby avoiding the occurrence of the film reversal phenomenon caused by the influence of the fixed block 20 during the inspection of the heat exchanger assembly. While realizing the quality inspection of the structural parts, the quality risks of the process caused by the inspection are effectively eliminated; wherein another suspension beam 2 is a movable support rod 27, and the movable support rod 27 cooperates with the support part to support and position the component to be inspected. The suspension bracket 11 includes a guide rail 111, and a scale 112 is arranged on the guide rail 111, which can be accurately positioned and adjusted according to the inspection requirements during use.

[0063] The protective structure serving as the support part is mainly composed of two types of protective bases: a stepped rubber base and a U-shaped rubber base. The purpose is to prevent the U-shaped copper tube at the bottom of the heat exchanger assembly from being bumped during the inspection process, which may cause leakage during subsequent use and affect the performance of the air-conditioning system.

[0064] The fixing block 20 is mainly divided into three categories: pipe joint module, pointed head module and platform module, which can be selected according to the type of the detection structure. During the detection process, the fixing block 20 can be screwed together with the lifting joint 22 by threading to achieve detection of different parts of different structures. In order to ensure the universality of detection, the internal structure of the pipe joint and the flat head module is designed with differential structure to adapt to the fixation of structures with different pipe diameters.

[0065] For the heat exchanger assembly 5, before testing, the ball screw structure below the present invention must be adjusted to move the suspension beam 2 close to the base baffle, and ensure that the component to be tested is placed nearly vertically, with the part to be tested facing upward, and the bottom U-shaped tube is protected by a rubber fixing block 20, while ensuring that the part to be tested is parallel to the flat-panel detector and on the same horizontal line. During the testing process, the component to be tested can be rotated at any circumferential angle according to the test situation to achieve multi-angle testing and analysis; for pipeline components, considering that the types of components are more complicated, a suspension method is adopted for testing. Different fixing blocks 20 can be selected according to the characteristics of the test components for effective fixing to ensure that the components are stable and do not shake during the testing process. For large-sized components, the screw can be adjusted by the suspension beam 2 to move them up and down to avoid interference with the suspension of large-sized components. Fig. 9 The heat exchanger assembly 5 is shown as being installed and fixed via the stepped U-shaped base 42 and the suspension beam 2 .

[0066] The device is designed as a stacked structure, which can be selected according to the detection requirements during the detection process. The suspension bracket 11 is equipped with a scale line on one side, and the position can be determined according to the detection requirements later, so as to facilitate rapid adjustment to the required height during the detection process.

[0067] During the implementation of the solution, all manually adjusted screw structures can be adjusted by motor drive to improve the adjustment accuracy and automation level of the equipment.

[0068] The automatic telescopic structure in this solution can also be realized by a rack mechanism, and the adjustment accuracy may deviate.

[0069] On the other hand, the present invention provides a detection device, including a detection unit and any of the above air conditioning component detection auxiliary positioning devices, the detection unit includes a flat-panel detector as a detection probe, and the flat-panel detector is located above the air conditioning component detection auxiliary positioning device.

[0070] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
