Description
Technical field
The utility model is related to the auxiliary power unit maintenance technique fields of airline carriers of passengers, and in particular to a kind of fanning strip table
Face machining fixing device.
Background technology
Fanning strip is the precision component with high speed rotation part such as rotor coordinating operation, the common damage packet of fanning strip
Include deformation and surface abrasion etc., it is therefore desirable to repairing sizes are carried out to the surface of fanning strip, when repairing fanning strip surface size,
Fanning strip accurate positioning should be limited fanning strip and occurs deviating or deform in processing again, and existing three-jaw or four paws
Structure can only screw stretching workpiece from perpendicular to the direction of Central of the parts line, and this fixed form can not only make three-jaw or four paws knot
Structure influences part surface to be processed, causes processing inconvenient, and contact stabilization is poor.
Invention content
The purpose of this utility model is to provide a kind of fanning strip surface machining fixing device, device positioning is accurate
Really, fastening is reliable, and does not interfere with the surface processing of part.
The purpose of this utility model is achieved through the following technical solutions：A kind of fixed dress of fanning strip surface machining
It puts, including pedestal, top board and lower platen, the pedestal carries the annulus of boss for a side end face, is set in the boss of pedestal
There is endoporus, and endoporus is stepped hole, the inner hole wall of pedestal is equipped with slideway, and top board is bolted on the upper table of slideway
Face, lower platen is located in the bottom surface of pedestal by least two positioning pins, and lower platen is fixedly connected by bolt with pedestal, under
Pressing plate carries the annulus of boss for a side end face, and the boss of lower platen is located in the endoporus of pedestal, and the boss and base of lower platen
Gap is formed between the inner hole wall of seat, pedestal side is additionally provided with multiple bolt of long stem for fixed sectors piece back side.
Further, the slideway carries the annulus of boss for a side end face, between the boss of slideway and pedestal inner hole wall
Form sliding slot.
The utility model, can be by fanning strip by the way that top board and lower platen to be distinguished to the top and bottom of fixed sectors piece
Piece surface exposes, consequently facilitating processing is repaired, and by the back side of bolt of long stem fixed sectors piece, can limit fanning strip
Position, to prevent fanning strip from displacement or deformation occur when processing and repairing.

Specific embodiment
As depicted in figs. 1 and 2, fanning strip surface provided in this embodiment machining includes pedestal 4, upper pressure with fixing device
Plate 6 and lower platen 2, pedestal 4 carry the annulus of boss for a side end face, are provided with endoporus in the boss of pedestal 4, endoporus is step
Hole, stepped hole have two layers, and the diameter of upper strata endoporus is more than the diameter of lower floor's endoporus, in pedestal 4 one on the inner hole wall of minor diameter
Body formed have a slideway 9, and slideway 9 carries the annulus of boss for middle part, the boss of slideway 9 and the inner hole wall of minor diameter in pedestal 4 it
Between form sliding slot, the protrusion at the 8 top back side of fanning strip is connected in sliding slot, makes 8 Primary Location of fanning strip on pedestal 4, upper pressure
Plate 6 is fixed on the upper surface of small diameter inner hole in slideway 9 and pedestal 4 by bolt 5, top board 6 can fixed sectors piece 8 top
Portion, the bottom surface of pedestal 4 are fixed there are two positioning pin 3, and lower platen 2 is located in the bottom surface of pedestal 4 by positioning pin 3 and passes through bolt
1 is fixedly connected with pedestal 4, and lower platen 2 carries the annulus of boss for a side end face, and the boss of lower platen 2 is located at the endoporus of pedestal 4
In, and gap is formed between the inner hole wall of minor diameter in the boss of lower platen 2 and pedestal 4, which is used to be clamped fanning strip 8
The protrusion of bottom rear, the side of pedestal 4 are additionally provided with multiple bolt of long stem 7 for being used to connect 8 back side of fanning strip.
The course of work of the utility model is：First the protrusion of 8 top back side of fanning strip is connected in the sliding slot of slideway 9,
Lower platen 2 by positioning pin 3 is located in the bottom of pedestal 4 again, makes the boss of lower platen 2 by the convex of 8 bottom rear of fanning strip
It rises and is pressed on the small diameter inner hole wall of pedestal 4, tightening bolt 1 makes lower platen 2 be fixedly connected with pedestal 4, then by top board 6
The top of fanning strip 8 is pressed on, the position that bolt 5 further positions fanning strip 8 is tightened, finally screws in the multiple of 4 side of pedestal
Bolt of long stem 7 connect bolt of long stem 7 and the bolt hole at 8 back side of fanning strip, so as to fulfill the abundant fixation of fanning strip 8.
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 novel protection domain.
