Description

Technical Field

[0001] This invention relates to the technical field of tower fan testing fixtures, and in particular to an automatic testing fixture for tower fan withstand pressure testing. Background Technology

[0002] In the production of tower fans, pressure resistance is a key indicator to ensure their safe use. Traditional tower fan pressure tests are mostly conducted manually with handheld pressure rods, which suffers from low testing efficiency and significant susceptibility to human error in the accuracy of test results. Moreover, manual testing makes it difficult to achieve precise control of the testing process and accurate data recording, failing to meet the demands of large-scale production and high-quality testing. Summary of the Invention

[0003] The present invention aims to overcome the shortcomings of low efficiency and low testing accuracy in the prior art by providing an automated testing fixture for tower fan withstand voltage testing that can automate the testing operation and improve testing efficiency and accuracy.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automated testing fixture for tower fan withstand voltage testing includes: A base, wherein a positioning template is fixed on the upper surface of the base; An adjustable cylinder one is placed on the base and on the side of the positioning template. The height of the adjustable cylinder one is higher than the upper surface of the positioning template. An adjustable cylinder two is fixed to one end of the movable rod of the adjustable cylinder one. The adjustable cylinder two is placed above the positioning template. A pressure block is fixedly connected to the lower end of the movable rod of the adjustable cylinder two. The pressure block is placed above the positioning template. The remote control controller is fixed inside both the adjustable cylinder one and the adjustable cylinder two; The test probes are of several kinds and are all placed on the lower end face of the pressure block, and the upper end of the test probes is inserted into the lower end face of the pressure block. A programmable controller is fixed to the upper surface of the base; The solenoid valve is fixed on the upper surface of the base. The solenoid valve, remote controller, and test probe are all connected and controlled by a programmable controller.

[0005] During use, first install each component on the base according to the design requirements, ensuring a secure connection and correct electrical wiring. After installation, perform equipment debugging, including stroke calibration of adjustable cylinder one and adjustable cylinder two, solenoid valve operation testing, and programmable controller program debugging, to ensure the normal operation of each component. Then, place the tower fan to be tested on the positioning template, and use adjustable cylinder one and adjustable cylinder two to move the pressure block to the corresponding position. The pressure block then presses down on the tower fan. To increase stability, the test probe contacts the tower fan. Connect the external withstand voltage tester to the socket, and the operator presses the start reset switch, and the equipment enters the initialization state. During the test, the equipment automatically executes the positioning, testing, and result judgment procedures. If any abnormal situation occurs during the test (such as excessive test current or equipment failure), the withstand voltage tester automatically stops the test and issues an alarm signal. After the test is completed, based on the test results, the equipment performs the corresponding reset operation, and the operator removes the tower fan, completing one test cycle. This achieves the goal of automating the tower fan withstand voltage test operation and improving testing efficiency and accuracy.

[0006] Preferably, the upper surface of the positioning mold is provided with a limiting groove. The limiting groove has an arc-shaped cross-section, and one end of the limiting groove is connected to one side of the positioning mold. Sensors are fixed at the center of the lower surface of the pressure block and on the center line of the limiting groove. The sensors are connected to a programmable controller and are interconnected. The limiting groove increases the placement stability of the tower fan, and the sensors help the pressure block quickly reach the appropriate position.

[0007] Preferably, the pressure block is provided with several limiting rods, which pass through the upper end face of the pressure block and are positioned below it. The limiting rods are threadedly connected to the pressure block. The limiting rods increase the installation stability of the tower fan.

[0009] Preferably, a start / reset switch is fixedly connected to the base, and the start / reset switch is connected to both the programmable controller and the solenoid valve. The start / reset switch facilitates the operator's reset of the equipment at the start and end of the test, making operation simple and convenient.

[0010] Preferably, a socket is fixedly connected to the base. The socket facilitates the connection of an external test power supply and data acquisition equipment.

[0011] Preferably, the programmable controller includes a data acquisition unit, which is electrically connected to the programmable controller. The data acquisition unit can collect and summarize multiple sets of data for convenient statistical analysis.

[0012] Preferably, the pressure block is provided with several insertion interfaces, through which the test probe is inserted into the pressure block. The insertion interfaces facilitate the replacement or repositioning of the test probe.

[0013] Preferably, a display screen is mounted on the outer surface of the programmable controller, and the programmable controller is electrically connected to the display screen. The display screen facilitates the display of data, warning lights, etc.

[0014] Preferably, the base is made of aluminum alloy, and the positioning template is made of bakelite. By utilizing the insulation of bakelite and the rigidity of aluminum, the positioning template is made to accurately position and fix the tower fan, ensuring safety and preventing displacement during testing.

[0015] The beneficial effects of this invention are: it automates the tower fan withstand pressure test operation, improving testing efficiency and accuracy; the limiting groove increases the placement stability of the tower fan, and the sensor helps the pressure block quickly reach the appropriate position; the limiting rod increases the installation stability of the tower fan; the waterproof cover protects the solenoid valve and increases its service life; the start-up reset switch facilitates the operator's equipment reset operation at the start and end of the test, making operation simple and convenient; the socket facilitates connection to external test power supplies and data acquisition equipment; the data acquisition unit can collect and summarize multiple sets of data for easy statistics; the plug interface facilitates the replacement or repositioning of test probes; the display screen facilitates the display of data warning lights, etc.; utilizing the insulation of bakelite and the rigidity of aluminum blocks to create a positioning template, it accurately positions and fixes the tower fan, ensuring safety and preventing displacement during the test.
