Embodiment Construction
[0023] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0024] This embodiment provides a spring load simulation device with adjustable load, see the attached figure 1 and figure 2 , including: load spring 6, outer shell 1, support 2, shear pin 7, locking pin 3, mounting seat 4, spring sleeve 5 and limit rod 8;
[0025] The outer casing 1 is a cylindrical structure with both ends closed, and one end is processed with a through hole, and the other end is processed with a threaded hole, and a limit rod 8 is installed in the threaded hole; the outer casing 1 is supported by a support 2 installed at the bottom on the support plane;
[0026] The load spring 6 is installed in the outer shell 1 through two spring sleeves 5 sleeved at its two ends, wherein one end of the spring sleeve 5 is open and the other end is closed, and an annular groove coaxial with it is processed at the open end. The end of loading spring...

The invention discloses a spring load simulation device with an adjustable load, and belongs to the technical field of load simulation. The device comprises load springs, an outer shell, a locking mechanism, a mounting seat, spring sleeves and a spacing rod, wherein the spacing rod is installed in the outer shell; the load spring is independently installed in the outer shell through two spring sleeves sheathed to two ends of the load spring; two spring sleeves are independently a spring sleeve A and a spring sleeve B; the sealing end of the spring sleeve A and the inner end surface of the outer shell are abutted; the sealing end of the spring sleeve B and the end part of the spacing rod in the outer shell are abutted to enable the load springs to be under a compression state; an end wherethe through hole of the outer shell is positioned is fixedly provided with the mounting seat; the piston rod of an actuation-type fire work device penetrates through the through hole of the outer shell to be in contact with the end surface of the sealing end of the spring sleeve A; and when the spring sleeve A moves along the direction of the spacing rod to a proper position, the spring sleeve A is locked through the locking mechanism. By use of the device, testing efficiency can be improved, development expenditure is saved, and development periods are shortened.
Description
technical field [0001] The invention belongs to the technical field of load simulation, and in particular relates to a spring load simulation device with adjustable load. Background technique [0002] The ground performance test is required for the actuating pyrotechnic device in the development stage. The load simulation test bench capable of simulating the force on the wing and the rudder surface is an indispensable equipment. Currently, most of the test benches used are electric loading load simulators and Pneumatic loading type load simulation device. [0003] Electric load simulators and pneumatic load simulators are generally more expensive, depending on the loading principle, the price is 1.5 million to 6 million, and the use and maintenance costs of the above two test benches are relatively high, and a lot of preparation is required before use. Work. Contents of the invention [0004] In view of this, the present invention provides a load-adjustable spring load s...
