introduction：The differential indexing method connects the main shaft of the indexing head and the side shaft of the exchange wheel with the exchange teeth in time，Its connected to the index dial，And loosen its sturdy screws，In this way, when turning the dividing handle to divide，The actual number of revolutions of the handle will be equal to the number of revolutions of the handle relative to the index plate will be equal to the difference between the number of revolutions of the handle relative to the index plate and the revolution of the index plate itself，In order to realize that the values are not commensurable and there is no corresponding hole ring on the parting plate。

introduction：The method of controlling the turning stop of precision divider is introduced： 1、Dividers generally have4Division and six division，One end of the splitter is driven by a motor，The other end serves as the control part，Judging by the proximity switch，The start and positioning of the motor are judged by the proximity switch。 2、For example4Segmented speaking，The other end of the splitter has a round metal body with a quarter notch，And the proximity switch is sensing this metal，Per revolution，A quarter of the gap is imperceptible，That means the splitter is in place，You can stop.，That should put the stop in place。

introduction：There are three modes of heat dissipation for switching power supplies：Natural cooling、Fan cooling、A combination of fan and natural cooling。 1、Natural cooling Natural cooling method is the traditional cooling method in the early stage of switching power supply，This method mainly relies on a large metal radiator for direct heat conduction heat dissipation。Heat exchange capacityQ=KA△t(KHeat transfer coefficient，AHeat transfer area，△tTemperature difference)。When the rectifier output power increases，The temperature of its power element will rise，△tThe temperature difference also increased，So when the rectifierAWhen the heat transfer area is satisfied，Its heat dissipation is no time lag，The power element has a small temperature difference，The thermal stress and thermal shock are small。However, the primary defect of this method is the large size and weight of the heat sink。Transformers are wound to reduce temperature rise as much as possible，Prevent temperature rise from affecting its operating performance，So its d
