Description

Technical Field

[0001] This utility model relates to the field of magnetic core ejection force detection technology, and more specifically to a detection device for measuring magnetic core ejection force. Background Technology

[0002] The push-pull force testing method is used to measure the holding force of a magnetic core within a coil. It reduces measurement error and achieves accurate measurement of the holding force by applying a force gauge to the end face of the magnetic core while holding the coil in place. The testing station consists of an inductor mounting block, a push-pull force gauge, an electrical control unit, and a base. It can operate automatically and also allows for the measurement of the push-pull force of products of different specifications.

[0003] Traditional detection methods have limited measurement range, uneven force during measurement, and significant measurement errors, failing to accurately reflect specific numerical values. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a detection device for measuring the pushing force of a magnetic core, which solves the problems of traditional detection methods, such as limited measurement range, uneven force during measurement, large measurement errors, and inability to accurately reflect specific values.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detection device for measuring the thrust of a magnetic core, comprising: a base, an electrically controlled fixing block disposed on the upper part of the base and a backrest plate disposed on the side of the electrically controlled fixing block, an electrically controlled unit disposed on the side of the backrest plate and a thrust gauge disposed at the output end of the electrically controlled unit, a limit block disposed on the upper part of the base and a support plate disposed on the upper part of the limit block, an inductor fixing block disposed on the upper part of the support plate and an inductor fixing block having an installation groove disposed inside the inductor fixing block, the installation groove corresponding to the thrust gauge.

[0006] In a preferred embodiment of this utility model, the inductor fixing block is provided with a positioning hole inside and the surface of the support plate is provided with a positioning post corresponding to it.

[0007] In a preferred embodiment of the present invention, the side of the mounting groove is provided with an outwardly extending slot.

[0008] In a preferred embodiment of this utility model, a guide rod is provided on the side of the backrest panel and the guide rod is connected to the thrust gauge.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention features an electrically controlled fixing block on the upper part of a base, with a backrest plate on its side. An electrical control unit is located on the side of the backrest plate, and a thrust gauge is installed at the output end of the electrical control unit. An inductor fixing block is also located on the upper part of the base, with a mounting groove inside the inductor fixing block. The mounting groove corresponds to the thrust gauge. The electrical control unit controls the thrust gauge to move downward at a uniform speed to contact the corresponding inductor core in the inductor fixing block, pushing out the core inside the coil. The value on the thrust gauge is read, and the pushed-out core and coil are removed from the fixing block before the next product measurement can be performed. The motor of the electrical control unit drives the thrust gauge to move up and down stably, ensuring uniform force on the core. This allows for accurate measurement of the holding force of the core within the coil at different downward pressure speeds. Compared to traditional tubular thrust gauges, this method offers higher accuracy and provides a more intuitive display of the specific values. Attached Figure Description
