Abstract
Description
Technical Field
[0001] This application relates to the field of fan testing, and more specifically, to a multi-station testing device for fan production. Background Technology
[0002] Industrial fans are widely used in large spaces such as industrial plants, logistics warehouses, waiting rooms, exhibition halls, stadiums, and shopping malls. As the preferred solution for space ventilation and personnel cooling, they can most efficiently drive a large amount of air movement, generate a huge air volume, and create a moving and circulating airflow field in the space, effectively solving the air circulation problem in industrial production workshops.
[0003] Industrial fans need to undergo strength testing on a strength testing machine before leaving the factory. 1. When installing the fan, multiple fasteners are required to fix the fan to the machine, making the installation process complicated and time-consuming, and inconvenient for installers. 2. When the fan is subjected to strength testing, the fan often throws out small parts under external pressure, which can scratch nearby operators, resulting in low safety.
[0004] Chinese patent application CN202320042326.5 discloses a machine for testing the strength of an industrial fan, including a fixed plate, protective covers, and elastic components. A base is fixedly connected to the bottom of the fixed plate, and two protective covers are provided on the base. A fixing block is provided inside the protective cover. When the fan is placed between four clamping plates, the clamping plates will expand and contract according to the size of the fan through the elastic adaptive force of the elastic components, so that the side of the four clamping plates closest to the fan is always in close contact with the fan and clamps it. The four circularly arranged clamping plates can be positioned for fans of different sizes and shapes through the elastic components, making the fan installation process simpler and easier to operate.
[0005] The above solution also has the following shortcomings: When in use, the fan strength testing machine is not easy to test the strength of multiple fans at the same time, resulting in low batch testing efficiency. At the same time, the opening and closing of the protective cover requires manual operation of the slide rail and limit block structure. Before and after the test, the handle needs to be pulled repeatedly and the position of the protective cover needs to be adjusted. The operation process is cumbersome, which increases time and labor costs, especially in frequent testing scenarios, thereby reducing the practicality of the device. Utility Model Content

The servo motor 121 is installed inside the worktable 110, the rotating shaft 122 is connected to the output end of the servo motor 121, and the rotating shaft 122 is rotatably connected to the worktable 110. The turntable 123 is fixedly connected to one end of the rotating shaft 122. The configuration of the servo motor 121, the rotating shaft 122, and the turntable 123 facilitates the loading and unloading of the fan, thereby improving work efficiency.
[0033] In the specific setup, a support plate 140 is provided on one side of the workbench 110, and the turntable 123 is attached to the support plate 140. The attachment of the turntable 123 to the support plate 140 facilitates support and ensures structural stability during fan testing.
[0034] In a specific configuration, an elastic component 130 is provided inside the turntable 123. The elastic component 130 includes a placement slot 131, a clamping plate 132, and a second spring 133. Several placement slots 131 are evenly distributed on one side of the turntable 123. The four inner walls of each placement slot 131 are provided with a second spring 133. The clamping plate 132 is fixedly connected to the second spring 133. The placement slots 131, the clamping plate 132, and the second spring 133 facilitate the fixing of fans of different diameters.
[0035] In a specific configuration, a slide bar 150 is provided on one side of the clamping plate 132. The slide bar 150 is slidably connected to the turntable 123. The slidable connection between the slide bar 150 and the turntable 123 facilitates the limitation of the movement of the clamping plate 132.
[0036] Please see Figure 1 and Figure 4 The test structure 20 includes a U-shaped support frame 210, two hydraulic cylinders 220, a protective cover 230, a first spring 240, a sliding plate 250, and a pressure plate 260. The U-shaped support frame 210 is fixedly connected to the workbench 110. The two hydraulic cylinders 220 are installed in parallel on one side of the U-shaped support frame 210. The movable ends of the two hydraulic cylinders 220 are provided with sliding plates 250. The protective cover 230 is slidably connected to the hydraulic cylinders 220. The two ends of the first spring 240 are respectively connected to the inner walls of the sliding plate 250 and the protective cover 230. The pressure plate 260 is fixedly connected to one side of the sliding plate 250.
[0037] In the specific setup, a control panel is provided on one side of the U-shaped support frame 210. The hydraulic cylinder 220 and the servo motor 121 are both electrically connected to the control panel.

[0039] In the specific setup, a viewing window is embedded on one side of the protective cover 230, which facilitates the user's observation of the test situation.
[0040] The working principle of the multi-station testing device for fan production is as follows: When using the multi-station testing device for fan production, the fan to be tested is placed in the placement slot 131 of the turntable 123. The four second springs 133 of the elastic component 130 push the clamping plate 132 to adaptively clamp the fan. The slide rod 150 is slidably connected to the turntable 123 to limit the offset of the clamping plate 132. The servo motor 121 drives the turntable 123 to rotate through the rotating shaft 122. The support plate 140 fits against the bottom surface of the turntable 123 to enhance the load-bearing stability and realize the cyclic switching of multiple stations. During testing, the hydraulic cylinders 220 on the U-shaped support frame 210 are activated. The slide plate 250 is pushed vertically downward along the inner wall groove of the protective cover 230. The first spring 240 is stretched, which drives the protective cover 230 to move, so that the protective cover 230 fits with the turntable 123 to form a sealed space for protection. At the same time, the pressure plate 260 connected to the slide plate 250 applies pressure to the fan to test the fan strength, which facilitates simultaneous testing at multiple stations and improves testing efficiency. After the test is completed, the hydraulic cylinder 220 retracts, the first spring 240 resets, and the protective cover 230 resets, which facilitates the automatic opening and closing of the protective cover 230. The turntable 123 is driven by the servo motor 121 to rotate to the next station, and the batch test is completed in a cycle.
[0041] It should be noted that the specific models and specifications of the servo motor 121 and hydraulic cylinder 220 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0042] The power supply and operating principle of the servo motor 121 and the hydraulic cylinder 220 are clear to those skilled in the art and will not be described in detail here.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
