Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of transformer detection devices, and in particular relates to a transformer pin length detection device. Background Art
[0002] Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: power transformer and special transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mining transformer, audio transformer, medium frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, mutual inductor, etc.). Circuit symbols often use T as the beginning of the number. For example: T01, T201, etc.; in the production process of transformers, various tests need to be performed on the transformer. Among them, the length of the transformer pin needs to be detected. If the transformer pin is too short, it will affect the stability of the subsequent plug-in process and the electrical connection effect. The existing transformer pin length detection method is to use CCD camera imaging and identification. This detection method is easily affected by the imaging effect and has detection uncertainty. At the same time, if there is mutual occlusion between the pins, it cannot be detected by this method. Utility Model Content
[0003] In view of the technical problem of inaccurate detection of the existing transformer pin length, the utility model provides a transformer pin length detection device, which can effectively detect the situation that the transformer pins are too short.
[0004] The utility model provides a transformer pin length detection device, comprising a sensor mounting seat, a spring mounting seat, a transformer fixing seat, a plurality of spring rods, a plurality of probes and a plurality of pressure sensors, wherein the transformer fixing seat is located above the spring mounting seat at intervals, the spring mounting seat is located above the sensor mounting seat at intervals, a plurality of pin holes are opened on the transformer fixing seat, a plurality of spring holes are opened at positions corresponding to the plurality of pin holes on the spring mounting seat, a plurality of spring rods are installed in the plurality of spring holes in a one-to-one correspondence, the tops of the plurality of probes extend into the plurality of pin holes in a one-to-one correspondence, the plurality of probes are connected to the plurality of spring rods in a one-to-one correspondence, a plurality of pressure sensors are arranged at positions of the sensor mounting seat corresponding to the plurality of probes, and the bottoms of the plurality of spring rods abut against the plurality of pressure sensors in a one-to-one correspondence.
[0005] Furthermore, a fixing block is provided on the top of the transformer fixing seat, and the fixing block is detachably mounted on the top of the transformer fixing seat, and a cavity for fixing the transformer is formed between the fixing block and the transformer fixing seat.
[0006] Furthermore, a base is included, and the sensor mounting seat is located on the base.
[0007] When the transformer pin length detection device is used to detect the pins of the transformer, the transformer can be fixed on the transformer fixing seat, and multiple pins of the transformer can be passed through the multiple pin holes one by one. The multiple pins press down the multiple probes, and the multiple probes then transmit the pressure to the multiple pressure sensors through the multiple spring rods. When the pins of the transformer are too short, the pressure sensor will have too little pressure. The pressure data of the pressure sensor can reflect whether the pins are too short. The device has the characteristics of sensitive response and high detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
