Detailed description of the invention
Below in conjunction with accompanying drawing 1, this utility model is described further.
A kind of visitor changes the fixed middle drill unit of pound columnar region seat guide rail fastener hole under goods aircraft, and including support 14, its lower end contacts with the guide rail section lower surface 23 of seat guide rail section bar 22；Center positioning device, it is arranged in support 14, and center positioning device is inserted in the circular hole clipping 24 of seat guide rail section bar 22；Commutation support 9, its relative centre positioner horizontally rotates setting；
N number of drilling-hole positioning device, with the center of center positioning device for the center of circle, along the circumferential direction uniform being installed on is commutated on support 9, drilling-hole positioning device is axially disposed the pilot hole 13 matched with drill bit, drilling-hole positioning device is inserted vertically in the circular hole clipping 24 of seat guide rail section bar 22 and its lower surface contacts with the drilling face 25 of circular hole clipping 24 lower end, and the distance at drilling-hole positioning device Center-to-Center positioner center is the integral multiple of the pitch-row of two adjacent circular hole clippings 24.Being placed in support 14 by seat guide rail section bar during use, inserted in circular hole clipping 24 by center positioning device afterwards, then be inserted into by drilling-hole positioning device in the circular hole clipping 24 needing boring, drill bit downwards can by drilling pore-forming on drilling face 25 along pilot hole 13.Integral multiple due to pitch-row that the distance at drilling-hole positioning device Center-to-Center positioner center is two adjacent circular hole clippings 24, therefore after completion of processing, commutation support 9 is rotated and next drilling-hole positioning device can be turned to this circle hole clipping 24 place, afterwards next one drilling-hole positioning device is inserted in this circle hole clipping 24, owing to pilot hole 13 diameter in different drilling-hole positioning devices can vary in size, therefore the reaming step by step from aperture to macropore of the hole of drilling can be made by constantly change drilling-hole positioning device so that it is meet the transformation standard of Boeing.Owing to pilot hole 13 is perpendicular with drilling face 25 all the time, therefore effectively guarantee the perpendicularity of boring, make securing member concentric with the circular hole clipping 24 of seat guide rail section bar 22 after mounting, improve working (machining) efficiency, improve machining accuracy.Further N is 4, pilot hole 13 diameter in four drilling-hole positioning devices respectively 1/8 inch, 3/16 inch, 7/32 inch and 1/4 inch.1/8 inch, 3/16 inch, 7/32 inch and 1/4 inch is four sizes the most frequently used in actual transformation, therefore further increases efficiency.
Drilling-hole positioning device can be following structure, it includes the locating dowel 17 being arranged at the through hole 10 on commutation support 9, the hollow bolt 12 being plugged in through hole 10 and matching with circular hole clipping 24, axially disposed in locating dowel 17 have locating dowel inner bolt hole 18, it is combined in locating dowel inner bolt hole 18 by hollow bolt 12 and is fixed on commutation support 9 lower end with vertical state, and axially disposed in hollow bolt 12 have pilot hole 13.Locating dowel 17 is inserted in circular hole clipping 24, and drill bit pilot hole 13 in hollow bolt 12 straight down, completes guiding drilling, and locating dowel 17 is simple and convenient with the mounting structure of hollow bolt 12, when worn, is also convenient for changing.Support 4 can be C-shaped configuration, is entered from the opening of the support 4 of C-shaped configuration by seat guide rail section bar 22 during installation, is fixed on seat guide rail section bar 22 by support 4 thus convenient.
Support 4 lower end can be provided with nylon anvil block 16, and the guide rail section lower surface 23 of seat guide rail section bar 22 contacts with nylon anvil block 16.Nylon anvil block 16 can effectively prevent the crush injury that the guide rail section lower surface 23 of seat guide rail section bar 22 is caused by clamping after-poppet 4, improves the reliability of use.
Locking system can also be included, when center positioning device and a drilling-hole positioning device are plugged in two circular hole clippings 24 simultaneously, locking system is by locked fixing for the position of commutation support 9, when drilling-hole positioning device departs from from circular hole clipping 24, locking system unlocks, and commutation support 9 is freely rotatable.nullConcrete，Locking system is following structure，It includes swingle 3、Commutation driver-extractor 6 and upper ratchet 19，Described center positioning device is bottom ratchet wheel 20，Swingle 3 top is provided with threaded upper ends 2，Its bottom is provided with lower end screw thread 5，Swingle 3 is vertically combined in the internal thread hole 15 of support 14 upper end by threaded upper ends 2，Position, intermediate portion slip cap is loaded in the endoporus of commutation driver-extractor 6，Commutation support 9 center is provided with commutation support screwed hole 11，Commutation driver-extractor 6 is vertically screwed by the external screw thread 8 that its lower end is arranged and is fixed in commutation support screwed hole 11，Upper ratchet 19 is installed on commutation support 9 lower end，Bottom ratchet wheel 20 is screwed on the lower end screw thread 5 being fixed on swingle by ratchet internal thread hole 21，When center positioning device and a drilling-hole positioning device are plugged in two circular hole clippings 24 simultaneously, upper ratchet 19 is meshed with bottom ratchet wheel 20.The support 9 that commutates after engaging with bottom ratchet wheel 20 due to upper ratchet 19 cannot rotate, it is achieved that lockup state, when needs change drilling-hole positioning device, commutation driver-extractor 6 is upwards pulled out along swingle 3, commutation driver-extractor 6 drives and moves on commutation support 9, thus upper ratchet 19 departs from bottom ratchet wheel 20, and drilling-hole positioning device departs from from circular hole clipping 24, commutation support 9 can be rotated afterwards, next drilling-hole positioning device is made to be rotated in place, rear drive commutation driver-extractor 6 move down, while making the drilling-hole positioning device after replacing be inserted in this circle hole clipping 24, upper ratchet 19 engages again with bottom ratchet wheel 20, realize locking.
In order to improve operation ease during rotation, it is also possible to include the star grip knob 1 being arranged at swingle 3 top.And it is arranged at the star commutation driver-extractor handwheel 7 with chamfering structure on commutation driver-extractor 6 top.The clamping device of power tool or drilling drill bit will not be produced to interfere by the depressed area of commutation driver-extractor handwheel 7.Further, it is also possible to include the spring 4 being set on swingle 3, the upper and lower side of spring 4 contacts with commutation support 14 and commutation driver-extractor 6 respectively.When pulling up commutation driver-extractor 6, spring 4 is compressed, and after commutation support 9 completes commutation afterwards, spring 4 can drive commutation driver-extractor 6 to move down, and making ratchet 19 again engage with bottom ratchet wheel 20, thus realizing locking, further increasing the convenience of operation.
