Abstract
The utility model brings forward a vibration test clamp, capable of rapidly reversing, for a solid rocket engine compartment segment. The vibration test clamp is composed of a clamp base plate, an installing plate and rolling balls. The clamp base plate is a circular base plate. The installing plate is of a cylindrical structure, a groove is disposed in the outer side surface of the installing plate, and the rolling balls are embedded into the groove. The clamp base plate and the installing plate are welded and fixed in a coaxial manner. When the installing plate and a solid rocket engine compartment segment are cooperated for installation, the inner side surface of the solid rocket engine compartment segment is in clearance fit with the outer side surface of the installing plate, and can fit the rolling balls and rotate around the axis of the segment itself. The installing plate and the solid rocket engine compartment segment are cooperated through the rolling balls, a testpiece is fixed and locked via bolts during a test, rapid reversing can be achieved as long as the locking bolts are loosened with no need of hoisting equipment, and the solid rocket engine compartment segment is prevented from being hoisted because of being too high so that inconvenient and unsafe problems are overcome.

Solid propellant rocket cabin section and missile equipment thereof can be vibrated and the effect of the dynamics environment such as impact in development, use and transportation, in order to check the working condition of product under true environment, specify according to national military standard, must carry out random vibration test, to verify reliability and the environmental suitability of product.In test, product is arranged on vibration table and realizes the requirement that multiple directions are tested in order to be held water, conventionally adopt fixture to connect product and shaking table, and be delivered on product distortionless the vibration signal on vibration table by fixture, realize the test examination to product, with reliability and the environmental suitability of checking product, can make like this vibration test more approach service condition, avoid undertesting or overtesting.
Vibration test is the important component part of environmental test, and fixture is being brought into play very important effect in vibration test.The function of vibration test fixture is, from shaking table, mechanical energy is passed to test specimen.Fixture is to design weight minimum, rigidity maximum, safe, easy for installation, simple to operate, fixture that can recurring structure resonance within the scope of test frequency in the difficulty running into aspect overall design.
Because solid propellant rocket cabin section testpieces size is higher, in the time of test, testpieces outer wall posts the sensors such as the strain of many roads, temperature, electric current, conventional design mode is large in shaking table slide unit controlling test difficulty, the low error of measuring accuracy is large, Product Assembly difficulty, when commutation, need Large-scale Hoisting equipment and a lot of testing crew co-operate, waste time and energy, security is low.
Summary of the invention
The technical matters solving
The problem existing for solving prior art, the utility model proposes a kind of solid propellant rocket cabin section vibration test fixture that can commutate fast, addressing the above problem the requirement of docking having met again with product simultaneously, and there is higher rigidity, the vibrational energy of shaking table can be delivered on underproof product effectively.
Technical scheme
The technical solution of the utility model is:
Described a kind of solid propellant rocket cabin section vibration test fixture that can commutate fast, is characterized in that: be made up of clamp bottom board, installing plate and ball; Clamp bottom board is annulus base plate, has with shaking table the mounting hole that docks use is installed on clamp bottom board; Installing plate is column structure, has a circle groove at installing plate lateral surface, has been embedded in ball at groove, and ball can roll in groove, also has the fixed orifice for being fixedly connected with solid propellant rocket cabin section madial wall on installing plate lateral surface; Clamp bottom board and installing plate coaxial welding are fixed, installing plate coordinates with solid propellant rocket cabin section while installation, solid propellant rocket cabin section medial surface and installing plate lateral surface clearance fit, and can fit ball rotating around self axis of solid propellant rocket cabin section medial surface.
Described a kind of solid propellant rocket cabin section vibration test fixture that can commutate fast, is characterized in that: be made up of clamp bottom board, installing plate, ball and adaptor; Clamp bottom board is annulus base plate, has with adaptor the mounting hole that docks use is installed on clamp bottom board; Installing plate is column structure, has a circle groove at installing plate lateral surface, has been embedded in ball at groove, and ball can roll in groove, also has the fixed orifice for being fixedly connected with solid propellant rocket cabin section madial wall on installing plate lateral surface; Adaptor is hollow round table structure, on adaptor sidewall, has view window; Adaptor one end and shaking table fixed installation, the adaptor other end is coaxially fixedly connected with clamp bottom board; Clamp bottom board and installing plate coaxial welding are fixed, installing plate coordinates with solid propellant rocket cabin section while installation, solid propellant rocket cabin section medial surface and installing plate lateral surface clearance fit, and can fit ball rotating around self axis of solid propellant rocket cabin section medial surface.
Beneficial effect
In this device, installing plate adopts ball to coordinate with solid propellant rocket cabin section, at the trial with bolt by testpieces fixing and locking, when commutation, as long as clamping screw is unclamped and do not needing to have realized quick commutation in hanging device situation, while having avoided commutation that solid propellant rocket cabin section superelevation causes, need to lift and inconvenient and unsafe problem.Adopt this device will greatly save the time and artificial, ensured the safety of test specimen in process of the test simultaneously, avoided the generation of accident, improved test efficiency and security, reduced experimentation cost.
