Description
Technical field
The utility model belongs to precision assembly field, and in particular to a kind of little gear suitable for inertial measuring unit is dismantled
Device.
Background technology
Inertial measuring unit applies the advantage in weaponry with self-calibration.It is related to gear during the used group precision assembly
Dismounting, gear assembling typically coordinated and gear axis connection using interference fits or small―gap suture.Original method for dismounting is to use hand
Gear is uniformly rapped by copper rod makes gear axial direction movement under force to reach the purpose of dismounting.This method both can be because of sky in dismounting
Between deficiency and be not easy to exert a force, again can because manual operations force it is uneven, cause axle or gear destruction.
Inertial measuring unit belongs to precision instruments, and the gap between motor and gear on gear shaft does not surpass typically
Cross 5 millimeters, conventional La Mayin insufficient spaces and can not use.Such as a kind of drawing horse provided in patent CN201320059372.2
Including drag hook, the arm of force, connection screw thread pull bar on the arm of force, the arm of force is provided with locating slot, and drag hook is symmetrically movably installed in locating slot；
The top of thread is set with boosting-rod, and bottom is provided with support base.The drawing horse of this kind of structure is due to using drag hook stress, hook end
Contacted for, lifting surface area is small, easily scratches part.And insufficient strength, it is easy to pull.The drawing horse of existing jack catchs type
There are these defects.
For this close apparatus of inertial measuring unit, the space that drag hook or claw needs stretch into is extremely narrow and small, current
Structure can not stretch into, if it is desired to go deep into small space, certainly will reduce drag hook or claw manufactured size, can so cause again
Pull the insufficient strength of gear.
Utility model content
In order to more preferably control a used group precision assembly quality, the quality problems such as part injury caused by dismounting are reduced, and
Extremely narrow space is also easy to use.The utility model aims to provide a kind of little gear suitable for inertial measuring unit and torn open
Handler.
The utility model solve problem technical scheme be：A kind of little gear suitable for inertial measuring unit dismantles dress
Put, including support base, the accommodating cavity for penetrating support base both sides is radially provided with along support base；
Support base tail end is provided with the screwed hole connected with accommodating cavity along support base central axis, and screw thread is equipped with screwed hole
Push rod；
Support base front end is provided with the clamp that can seal accommodating resonator end surface, in radial directions from clamp center to clamp side
Edge is provided with U-shaped through hole.
The clamp of such scheme has a bigger area, is caught in gear shaft from the open side of U-shaped through hole during use, same in this
When, the gear on gear shaft enters accommodating cavity, and clamp abuts with gear face, then precession screw putter, allows screw thread
Push rod front end pushes against with gear shaft end face, and gear just by the power opposite with the screw putter direction of motion, makes gear transport vertically
It is dynamic, reach the purpose of dismounting gear.The whole plate face of clamp all contacts, stress in addition to U-shaped lead to the hole site with gear face
Evenly, will not pull.Due to being face contact, also gear face will not be caused to damage.It is big just because of contact area, so
Clamp can be done to relatively thin, the deep enough small space for being less than 5 millimeters of energy on the premise of enough power is provided.
Further, the screw putter front end is provided with push rod, and push rod front end is the conical surface.Because gear shaft is in process
In, axial end can centering as fabrication hole, design the push rod with the conical surface herein, it is therefore an objective to which screw putter supports with gear shaft
When connecing, the conical surface of push rod front end just docks with centre bore, ensures all the time along gear shaft axis uniform stressed.
The clamp thickness is no more than 5mm.
Further, sprocket drive spindle is inserted in the U-shaped through hole, the gap between U-shaped through hole and gear shaft outer surface is
0.2-0.5mm.The measure, which enables to clamp to make, has sufficiently large area.
Remarkable result of the present utility model is：
1. the whole plate face of clamp all contacts in addition to U-shaped lead to the hole site with gear face, stress evenly, Bu Huila
It is de-.Due to being face contact, also gear face will not be caused to damage.A used group precision assembly quality can more preferably be controlled, reduce because
The quality problems such as part injury caused by dismounting, reduce defective work, and efficiency of assembling is improved compared to dismounting is tapped.
2. because contact area is big, it is possible to clamp done on the premise of enough power is provided it is relatively thin, extremely narrow
Small space is also easy to use.
