Description

Temperature control actuator with state feedback and method

Technical Field

The invention relates to an electronic actuator, in particular to a temperature control actuator with state feedback and a method.

Background

The existing mainstream military product pin pulling and pushing device mainly uses gunpowder as a driving energy source, the gunpowder burns to generate air pressure to push a machine to generate pin pulling action, the pin pulling and pushing device can be used only once, the performance cannot be tested in the production process and after assembly, the test only mainly uses a small amount of pulling and testing, and the performance of batch products cannot be truly reflected; the testing of the initiating explosive device pin pulling device increases the testing cost and brings risks to the testing and the production. The development of the initiating explosive device products is limited due to the small number of enterprises with the initiating explosive device qualifications.

Based on the problems of low safety, high price and unrepeatable test of the initiating explosive device ejector pin, the electromagnet is also used as the ejector pin at present. The cost of the electromagnet is reduced to some extent, repeated testing can be carried out, and the use safety is also solved. However, the electromagnet also has a fatal weakness, the pulling pin force is not as large as that of an initiating explosive device, the state cannot be maintained, and the heating speed is high, because the pulling force of the electromagnet completely depends on the power supply, if the pulling force is increased, the power supply is increased, and the state is required to be maintained to continuously supply power, so that the load is increased on the spring power supply.

The smaller the required size on the bullet is, the better the size on the bullet is, and the larger the drawing force of the electromagnet is, the more the wire diameter of the electromagnet coil can be reduced and the number of turns of the coil can be increased in the limited space, so that the consequence is that the current resistance of the electromagnet is reduced, the electromagnet is easy to generate heat, the electromagnet is easy to burn out due to overheating during testing, and the coil is damaged to a certain extent even if the electromagnet is not damaged temporarily, thereby bringing hidden troubles to products.

At present, some products use a relay as an electric switch, but the relay also has problems in the use process, and because the relay also acts by the suction force of an electromagnet, the suction force of a contact is limited and cannot meet the use environment of large overload.

In summary, in order to realize the pushing and pulling actions of the pin puller and have the functions of repeated testing and feedback actions, researchers developed electronic actuators. However, with the increase of the intelligent requirement of ammunition, all products are developing towards miniaturization, and because the motor drive adopted in the ammunition is easy to be influenced by low temperature, the application of the products is limited. Therefore, the conventional techniques have problems that they are large in size and are easily affected by low temperature.
