Description
Technical field
The invention belongs to a kind of vibration test fixture, using the fixture can will missile launcher it is fixed after, complete it is vertical, The vibration test in three directions of transverse direction and longitudinal direction.
Background technique
Vibration test is a big event in environmental test, can be used to find in product design and production process Defect improves the purpose of the vibration resistance environment capacity of product to reach improvement product design.
Test indoor simulation guided missile passes through the vibration test for leading the guided missile for the truth that hair frame is suspended on aircraft at present, is It effectively examines guided missile and leads the most effective mode of hair frame vibration resistance ability.So a fixed missile launcher need to specially be made Vibration test fixture.
Summary of the invention
The purpose of the present invention：It proposes a kind of vibration test fixture, rigid connection fixation is carried out to suspension type missile launcher.
Technical solution of the present invention：
A kind of vibration test fixture, including：
Sliding block loose slot (1), movable slider (2), outer adjutage (3), connecting screw (4), pitman (5), ball screw (6), valve (7)；
Sliding block loose slot (1) is screwed on cage fixture, and pitman (5) are passed through to the lifting lug of missile launcher, make lifting lug Intermediate position in pitman (5)；Pitman (5) and two movable sliders (2) are subjected to clearance fit installation；Movable slider (2) from below in insertion sliding block loose slot (1)；Connecting screw (4) passes through the through-hole and movable slider on sliding block loose slot (1) (2) through-hole on the U-type groove of two sides and pitman (5) is fixed；Outer adjutage is installed on the outside of sliding block loose slot (1) (3)；Threaded hole is equipped on the outside of outer adjutage (3)；Valve (7) and ball screw (6) are sub-assembly, and valve (7) can be around bulb Screw rod (6) one end turns an angle；Ball screw (6) other end is screwed onto the threaded hole of outer adjutage (3)；Governor valve (7) position and angle, missile launcher is fixed.
The vibration test fixture is using 30CrMnSiA as making material.
Advantages of the present invention：Cooperated by the intercombination of several group parts and reasonable size design, reaches fixation and lead The purpose of launcher is played, and can be with the valve distance and different length of flexible choice different location when installing missile launcher Spiro rod length installed, can satisfy stationary phase with the technical requirements of lifting lug spacing but various sizes of missile launcher, Suitable for the missile launcher of multiple and different models, the experimentation cost of vibration test has been saved.
Detailed description of the invention：
Fig. 1 is the part combination part front view of the fixed lifting lug of the present invention.
Wherein：1 --- --- movable slider 3 --- outer adjutage 4 --- connecting screw of sliding block loose slot 2
5 --- pitman

Specific embodiment：
The invention will be described in further detail with reference to the accompanying drawing.
The present invention provides a kind of vibration test fixture, as shown in Figure 1,2,3, 4, including：
Sliding block loose slot 1, movable slider 2, outer adjutage 3, connecting screw 4, pitman 5, ball screw 6, valve 7；
Sliding block loose slot 1 is screwed on cage fixture, and pitman 5 is passed through to the lifting lug of missile launcher, is in lifting lug The intermediate position of pitman 5；Pitman 5 and two movable sliders 2 are subjected to clearance fit installation；Movable slider 2 is inserted into from below In sliding block loose slot 1；The U-type groove and connection that connecting screw 4 passes through through-hole and 2 two sides of movable slider on sliding block loose slot 1 Through-hole on stick 5 is fixed；Outer adjutage 3 is installed on the outside of sliding block loose slot 1；Threaded hole is equipped on the outside of outer adjutage 3；It is living Door 7 is sub-assembly with ball screw 6, and valve 7 can turn an angle around 6 one end of ball screw；6 other end spiral shell of ball screw It connects in the threaded hole of outer adjutage 3；The position of governor valve 7 and angle, missile launcher is fixed.
The vibration test fixture should be using the big material that meets with stresses, for example uses 30CrMnSiA as making material.
Use process：
The present invention is divided into two groups with piece pitman of two sliding blocks for one group and fixes two lifting lugs respectively.Pitman and sliding block Sliding slot is installed by clearance fit, this component is seated to sliding block loose slot, is reused screw rod and is passed through leading on sliding block loose slot Hole is fixed with the through-hole in the U-type groove and pitman of sliding block two sides；Outer adjutage is installed in the outside of sliding block loose slot And the sub-assembly of ball screw and valve, the specific position of valve is determined by the selection of the position of opening on outer adjutage It sets, thus fixed various sizes of missile launcher.
