Problems solved by technology
[0002] In the structure of the actuator, a process compensation part is generally designed to adjust the relative installation direction of the actuator joint and the outer cylinder and ensure the length of the actuator to meet the design requirements; after the actuator is assembled to meet the relative installation direction and working Due to the length requirement of the actuator, the process compensation parts need to be supplemented. However, due to the structural shape of the traditional actuator process compensation parts, it is necessary to disassemble the actuator and reassemble it to remove the process compensation parts, which increases the product assembly work. amount, and it is easy to cause damage to related parts, especially the sealing ring

An actuating cylinder structure achieving quick disassembling and adjustment comprises an outer barrel, one end of the outer barrel is sleeved with an upper joint, and the other end of the outer barrel is provided with a lower end cover. A technological compensation part is arranged between the upper joint and the outer barrel. The technological compensation part is of an open annular structure and is made of an elastic material. A piston rod penetrates through the lower end cover and extends into the outer barrel. An extension cavity pipe joint and a retraction cavity pipe joint are arranged on the outer barrel. The structural mode of the technological compensation part is improved, specifically, the structure of the technological compensation part is changed from an integral ring into an open ring, so that when the requirements for the relative installation direction and length of parts are not met after an actuating cylinder is assembled, and makeup machining needs to be carried out on the technological compensation part, an operator just needs to disassemble the technological compensation part instead of disassembling and reassembling the actuating cylinder, the product assembling efficiency is effectively improved, and the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to the technical field of aircraft structures, in particular to a quick-release and adjustable actuator structure. Background technique [0002] In the structure of the actuator, a process compensation part is generally designed to adjust the relative installation direction of the actuator joint and the outer cylinder and ensure the length of the actuator to meet the design requirements; after the actuator is assembled to meet the relative installation direction and working Due to the length requirement of the actuator, the process compensation parts need to be supplemented. However, due to the structural shape of the traditional actuator process compensation parts, it is necessary to disassemble the actuator and reassemble it to remove the process compensation parts, which increases the product assembly work. amount, and it is easy to cause damage to related parts, especially the sealing ring.
