Description
Technical field
It the utility model is related to airline carriers of passengers auxiliary power unit maintenance technique field, and in particular to a kind of gear-box processing
Use fixing device.
Background technology
Gear-box belongs to typical complicated and irregular mo(u)lded piece, and part machined surface has the morpheme public affairs of micron order
Difference requires, and size precision prescribed is higher.For the gear box structure processing request in airline carriers of passengers auxiliary power unit
Higher, while gear box structure asymmetry can cause centroid motion, therefore the gear-box processing to the type needs to design one kind
Fixed gear case upper surface but also the frock of lower face can be fixed, and also centroid position is accounted for, to ensure pair
Stability during two end face processing of gear-box.
The content of the invention
The purpose of this utility model is to provide a kind of simple in structure, clamping reliable gear-box processing fixing device.
The purpose of this utility model is achieved through the following technical solutions：A kind of gear-box processing fixing device, bag
Fixed seat and jacking apparatus are included, fixed seat includes center sleeve and the upper pallet and lower pallet that are fixed on center sleeve both ends,
The upper surface of upper pallet is equipped with multiple pressing plates arranged in a ring close to cylindrical place, and pressing plate is installed on upper pallet by bolt,
And backing plate is equipped between pressing plate and upper pallet, at least provided with a positioning pin on upper pallet, it is evenly provided with the lower pallet
Multiple threaded holes arranged in a ring；The jacking apparatus includes jacking screw rod and the jacking swivel nut for holding upper pallet.
Further, the quantity of the pressing plate for six and is evenly provided on upper pallet.
Further, the pressing plate is equipped with bar hole, and bolt is connected through bar hole with upper pallet.
Further, the pressing plate is equipped with compact heap close to the side at upper pallet center, and the lower edges of compact heap fall
There is angle.
Further, the quantity of the lower pallet upper screwed hole is eight.
The utility model is in assembling gear case, easy to operate, accurate positioning, and installation requirement is relatively low and will not be to part
Cause to damage, the time of assembling can be substantially reduced.

Embodiment
As shown in Figure 1 to 4, gear-box fixer for machining provided in this embodiment includes fixed seat and jacking apparatus 3,
Fixed seat is made of the upper pallet 1 and lower pallet 2 at 9 both ends of center sleeve 9 and center sleeve, and the upper surface of upper pallet 1 is close
Cylindrical place is evenly provided with six pressing plates 4 arranged in a ring, and is used for fixed gear case at least provided with one on upper pallet 1
The positioning pin 6 of 10 large round end surface, the pressing plate 4 are equipped with bar hole 7, and bolt screws in correspondence on upper pallet 1 after passing through bar hole 7
Screw hole in, so as to fulfill the mutual locking of pressing plate 4 and upper pallet 1.The lower section in the outside of pressing plate 4 is additionally provided with backing plate 5, the outside
Side of the acupressure probe 4 away from 1 center of upper pallet, the inner side of pressing plate 4 are equipped with compact heap, and in the present embodiment, compact heap is with pressing plate
Integrative-structure, the lower edges of compact heap have angle, which can avoid the rigidity mill of pressing plate 4 and 10 large round end surface of gear-box
Damage.The lower pallet 2 is less than the plectane of upper pallet 1 for diameter, and eight screw threads arranged in a ring are evenly provided with lower pallet 2
Hole 8.
The jacking apparatus 3 is located at the lower section of upper pallet 1, and jacking apparatus 3 includes jacking screw rod 32 and is set in jacking
Jacking swivel nut 31 on screw rod 32, jacking swivel nut 31 are used for the lower surface for holding upper pallet 1.
As shown in figure 5, the operation principle of the utility model is：, first will pressure when needing to process 10 roundlet end face of gear-box
Bolt is unscrewed on plate 4 so that pressing plate 4 can be displaced outwardly, and the large round end surface of gear-box 10 is bonded with the surface of upper pallet 1, be inserted
Entering positioning pin 6 prevents 10 displacement of gear-box, then promotes pressing plate 4 until pushing down the large round end surface of gear-box 10, tightens bolt, due to
Gear-box 10 is in irregular shape, jacking apparatus 3 is moved to the lower section of upper pallet 1 of that side of centre-of gravity shift, by screwing jacking spiral shell
Set 31 makes it hold upper pallet 1 so as to ensure the stability of whole device.When needing to process 10 large round end surface of gear-box, tear open
Lower tooth roller box 10 simultaneously overturns lower pallet 2 upward, while roundlet end face is inserted into 2 corresponding spiral shell of lower pallet the upset of gear-box 10
In pit 8, and with nut tighten can working gear-box 10 large round end surface.
The above is only the utility model preferred embodiment, but the scope of protection of the utility model is not limited to
This, any transformation carried out based on technical solution provided by the utility model and inventive concept and replacement should all be covered in this reality
With in new protection domain.
