Description
Technical field
This application involves bushing processing and manufacturing technology, especially a kind of eccentric bush line of symmetry engraves positioning device.
Background technique
In order to guarantee the structural compatibility of aircraft components or realize a certain movement exist in aircraft components motion structure a large amount of
Eccentric bush, the eccentric position of these eccentric bush of conventional mounting uses structure adaptive or rear finishing substantially, do not need
It is accurate to determine eccentric position.It is easy to cause bushing to rotate in adaptation process using the bushing of structure adaptive, if at the beginning of bushing
Holding position is improper, then be easy to cause bushing stress excessive or damage.According to airworthiness requirement, to the first dress position of this eccentric bush
It sets it needs to be determined that eccentric position, guarantees that bushing eccentric state meets structure basic demand when just dress.In addition, current machining is carved
Line be easy to cause sleeve surface concentration of tension forces, is easy to cause bushing to damage in use, so, using sharp in manufacturing process
Photoetching line.Laser scoring then needs to position structure, the position consistency of the position and laser scoring had good positioning.Due to
Eccentric bush will meet the quick of eccentric bush and position to solve production realistic problem in the extensive application of airplane motion mechanism,
There is an urgent need to study located in connection device and method.
Utility model content
The purpose of the application is to provide a kind of eccentric bush line of symmetry and engraves positioning device, which can be adapted for all kinds of
Eccentric bush line of symmetry engraves positioning and groove.
To achieve the above objectives, the application, which adopts the following technical scheme that, is achieved:
A kind of eccentric bush line of symmetry engraves positioning device, including dial gauge, bushing rotary shaft, pedestal, light-transmitting plate, turns
Disk, positioning pillars, bushing rotary shaft are installed on the base, and turntable is sleeved in bushing rotary shaft, and bushing rotary shaft drives turntable
It rotates on the base；Bushing rotary shaft and eccentric bush inner hole use, and the plate of cross hollow slots is provided with centered on light-transmitting plate
Shape part, and be fixed on right above pedestal top rotary table by positioning pillars, the symmetrical centre of the one of notch of cross hollow slots
The symmetrical centre face position consistency of face and eccentric bush inner hole and outer circle, dial gauge are arranged in side of base, dial indicator measuring head
Heart line is on the symmetrical centre face of eccentric bush inner hole and outer circle.Pedestal is made of bottom plate, placed cavity, turntable, magnet, bottom plate
The square plate structure of big chamfering is carried out for one jiao, placed cavity opens system respectively at bottom plate triangular, and placed cavity is intermediate hollow out
Turntable is arranged at big chamfering for " ┕ ┙ " structure, and rotating hole processed is opened at turntable center, and magnet is fixed in placed cavity.
The advantages of the application, is that dial gauge, which is utilized, surveys the basic principles such as outer circle and cross recess leakage laser, completes simple
A kind of easy, at low cost, high-efficient eccentric bush line of symmetry engraves positioning and groove, engraves positioning to eccentric bush line of symmetry
With general applicability.
The application is described in further detail with reference to the accompanying drawings and embodiments.
Detailed description of the invention
A kind of eccentric bush line of symmetry of Fig. 1 engraves positioning device structure figure；
Fig. 2 base construction figure；
Explanation: 1, dial gauge is numbered in figure；2, bushing rotary shaft；3, pedestal；4, light-transmitting plate；5, turntable；6, positioning pillars；
7, bottom plate；8, placed cavity；9, turntable；10, magnet；11, eccentric bush.
Specific embodiment
Referring to FIG. 1 to FIG. 2, a kind of eccentric bush line of symmetry engraves positioning device, including dial gauge 1, bushing rotary shaft 2,
Pedestal 3, light-transmitting plate 4, turntable 5, positioning pillars 6, bushing rotary shaft 2 are mounted on pedestal 3, and turntable 5 is sleeved on bushing rotary shaft
On 2, bushing rotary shaft 2 drives turntable 5 to rotate on pedestal 3；Bushing rotary shaft 2 and 11 inner hole of eccentric bush use, thoroughly
It is provided with the plate part of cross hollow slots centered on tabula rasa 4, and is fixed on right above 3 top rotary table of pedestal 5 by positioning pillars 6,
The symmetrical centre face position consistency of the symmetrical centre face of the one of notch of cross hollow slots and 11 inner hole of eccentric bush and outer circle,
Dial gauge 1 is arranged in 3 side of pedestal, and 1 gauge head center line of dial gauge is on the symmetrical centre face of 11 inner hole of eccentric bush and outer circle.
Pedestal 3 is made of bottom plate 7, placed cavity 8, turntable 9, magnet 10, and bottom plate 7 is one jiao of square for carrying out big chamfering
Hardened structure, placed cavity 8 open system respectively at bottom plate triangular, and placed cavity 8 is " ┕ ┙ " structure of intermediate hollow out, are arranged at big chamfering
Rotating hole processed is opened at turntable 9,9 center of turntable, and magnet 10 is fixed in placed cavity 8.
The method for carrying out positioning and groove using the device is as follows:
A, pedestal 3 is adsorbed on laser scoring platform；
B, eccentric bush 11 to be engraved is inserted into bushing and rotates fixing axle 2,1 gauge head of dial gauge is pressed on to be engraved inclined
11 outer rim of heart bushing；
C, rotary turnplate 5 drives bushing rotary shaft 2 to rotate, by the full-scale reading or most for reading the compression of 1 gauge head of dial gauge
Small reading determines 11 symmetrical centre face position of eccentric bush to be engraved；
D, light-transmitting plate 4 is fixed in positioning pillars, 4 lower surface of light-transmitting plate compacting table on eccentric bush 11 to be engraved
Face, laser carve 11 symmetrical center line of eccentric bush；
E, it removes light-transmitting plate and to complete the eccentric bush of groove, repeats 2-4 step, carry out next to be engraved inclined
The laser scoring of heart bushing.
