Description

Technical Field

[0001] This utility model relates to the field of fan inspection technology, specifically an inspection tool for automotive radiator fans. Background Technology

[0002] Existing automotive radiator fan inspection fixtures, such as the utility model patent with publication number CN203100611U, disclose an inspection fixture for an automotive radiator fan. It includes a base plate with a tray supporting the fan's air guard ring. The tray has protruding inspection posts for insertion into the screw holes of the air guard ring. Three protruding fixing posts are located on the base plate around the tray; two of these fixing posts have inspection holes, and the third has a side inspection hole. These inspection holes and side inspection holes correspond to the three mounting holes around the fan. The fixture also includes an insertion rod whose outer diameter mates with the inner diameter of the inspection holes and side inspection holes. Three inspection posts are arranged in a triangular pattern around the circular tray. The tray and fixing posts are fixed to pre-drilled fixing holes on the base plate using screws. The base plate has fixing holes for different fan models. The inspection posts are fixed to pre-drilled positioning holes on the tray using screws. The tray has positioning holes for different fan air guard ring models. The advantages of this invention are that the inspection fixture can quickly and effectively inspect the installation dimensions of multiple spaces in a radiator fan, and can simultaneously control the matching degree between the fan mounting holes and the motor mounting holes, ensuring the product's factory quality. To improve the versatility of the inspection equipment, the fixture's tray and fixing posts are fixed to pre-drilled fixing holes on the base plate with screws. The base plate has multiple sets of pre-drilled fixing holes for different fan models, and the inspection posts are also fixed to pre-drilled positioning holes on the tray with screws. The tray also has multiple pre-drilled positioning holes for different fan models' fan guards. Therefore, by simply changing the positions of the tray, fixing posts, and inspection posts, the fixture can adapt to the inspection of various fans, improving its utilization rate. Therefore, existing inspection tools for automotive radiator fans can usually only detect whether there is a deviation in the mounting hole position of the fan, but cannot detect the airflow of the fan. Therefore, it is necessary to design an inspection tool that can detect the airflow of automotive radiator fans. Utility Model Content

[0003] In view of the problems existing in the inspection tool for automotive radiator fans, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a tooling for inspecting automotive radiator fans, which solves the problem that existing automotive radiator fan tooling can usually only detect whether there is a deviation in the mounting hole position of the fan, but cannot detect the airflow of the fan. Therefore, it is necessary to design a tooling that can detect the airflow of automotive radiator fans.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A testing fixture for an automotive radiator fan includes a support platform with two support columns. A testing air duct is mounted on the support platform. A movable cylinder is slidably connected to the inner wall of the testing air duct. A sealing plate is connected to the left end of the testing air duct. A movable rod is fixedly connected to the left end of the movable cylinder. A spring is sleeved on the movable rod, and the spring is located between the sealing plate and the movable cylinder.

[0006] As a preferred embodiment of the inspection tool for an automotive radiator fan described in this utility model, the left end of the moving rod is provided with a scale line, an observation rod is welded on the support platform, the observation rod has a through hole for the moving rod to pass through, and the zero scale line of the moving rod is aligned with the left side of the observation rod.

[0007] As a preferred embodiment of the inspection fixture for an automotive radiator fan described in this utility model, a raised plate is welded to the bottom of the inspection fan duct, and the raised plate is fixed to the support platform by bolts.

[0008] As a preferred embodiment of the inspection tool for an automotive radiator fan described in this utility model, the bottom of the support column is slidably connected to the support platform, and a support block is welded onto the support platform. An electric push rod is installed between the support column and the support block.

[0009] As a preferred embodiment of the inspection fixture for an automotive radiator fan described in this utility model, a sliding groove is provided on the support platform, a slider is welded to the bottom of the support column, and the slider is slidably connected to the inner wall of the sliding groove.

[0010] In a preferred embodiment of the inspection fixture for an automotive radiator fan described in this utility model, a first support connecting seat is welded onto the support block, an electric push rod is inserted into the inner wall of the first support connecting seat, and the electric push rod and the first support connecting seat are fixed together by bolts.

[0012] Compared with existing technologies: By setting up a testing air duct, a movable cylinder is placed inside the testing air duct, and a spring is fitted on the movable rod on the left side of the movable cylinder. The movable cylinder is driven to move inside the testing air duct by the air force of the car radiator fan. The air force of the car radiator fan can be roughly determined by the compression length of the spring, thus enabling the testing of the air force of the car radiator fan.

[0013] By observing the distance the moving rod moves away from the observation rod, the amount of spring compression can be indirectly determined, making data observation more convenient. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] This utility model provides a tool for inspecting automotive radiator fans. Please refer to [link / reference]. Figure 1-4 The system includes a support platform 1, on which two support columns 4 are provided. A detection air duct 2 is installed on the support platform 1. A movable cylinder 15 is slidably connected to the inner wall of the detection air duct 2. A sealing disc 3 is connected to the left end of the detection air duct 2. A movable rod 12 is fixedly connected to the left end of the movable cylinder 15. A spring 14 is sleeved on the movable rod 12. The spring 14 is located between the sealing disc 3 and the movable cylinder 15.

[0018] The left end of the moving rod 12 is provided with a scale line, and an observation rod 13 is welded on the support platform 1. The observation rod 13 has a through hole for the moving rod 12 to pass through. The zero scale line of the moving rod 12 is aligned with the left side of the observation rod 13. Thus, when the car radiator fan 5 works and blows the moving cylinder 15, and the moving cylinder 15 moves to the left, the distance the moving rod 12 moves can be determined by observing the scale at the position where the left side of the moving rod 12 is aligned with the observation rod 13. This allows us to determine the contraction distance of the spring 14 and thus roughly determine the wind force of the car radiator fan 5.

[0019] A raised plate 11 is welded to the bottom of the testing air duct 2, and the raised plate 11 is fixed to the support platform 1 by bolts.

[0020] The bottom of the support column 4 is slidably connected to the support platform 1, and a support block 9 is welded onto the support platform 1. An electric push rod 6 is installed between the support column 4 and the support block 9. Specifically, a first support connecting seat 8 is welded onto the support block 9, and the electric push rod 6 is inserted into the inner wall of the first support connecting seat 8. The electric push rod 6 and the first support connecting seat 8 are fixed together by bolts. A second support connecting seat 7 is welded onto the support column 4, and the electric push rod 6 is inserted into the inner wall of the second support connecting seat 7. The electric push rod 6 and the second support connecting seat 7 are fixed together by bolts. The electric push rod 6 is used to drive the car radiator fan 5 installed on the support column 4 to move closer to the detection air duct 2, so that the airflow is more concentrated to drive the moving cylinder 15 to move within the detection air duct 2.

[0021] The support platform 1 is provided with a sliding groove, and the bottom of the support column 4 is welded with a slider 10, which is slidably connected to the inner wall of the sliding groove.

[0022] In practical use, bolts are used to fix the two sides of the car radiator fan 5 to the two support columns 4 respectively. The electric push rod 6 extends and drives the slider 10 to approach the detection air tube 2. Thus, the slider 10 drives the support column 4 to approach the detection air tube 2, and the support column 4 drives the car radiator fan 5 to approach the detection air tube 2. The moving tube 15 moves inside the detection air tube 2 under the action of wind force. By observing the distance of the moving rod 12 extending out of the observation rod 13, the contraction length of the spring 14 can be known. The magnitude of the force is calculated based on the spring contraction length and the elastic coefficient, so as to roughly know the wind force of the car radiator fan 5.

[0023] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
