Abstract
The invention discloses a drilling technique method of supports of seats, which is characterized in that a guide drilling jig is arranged on an overall positioning tool to drill holes; since a distance between two rows of the seats is the same, each row of the seats are on the same straight line, mounting holes in the two rows of the supports are drilled firstly; after the mounting holes in the two rows of the supports are drilled, then the following holes are drilled; the holes in the overall positioning tool coincide with the drilled holes, and then the overall positioning tool is fixedly arranged on the drilled holes by locating pins; and the other row of holes are drilled, then the following holes are drilled, so that the relative position between each row of holes is ensured. According to the invention, overall positioning of the mounting holes in every two rows of the supports of the seats is adopted; after the mounting holes in the two rows of the supports are drilled, the following holes are drilled; the holes in the tool coincide with the drilled holes, and then the tool is fixedly arranged on the drilled holes by the locating pins; the other row of holes are drilled, and then the following holes are drilled, so that the relative position between each row of holes is ensured better; working efficiency is effectively improved; compared with drilling one by one by using a magnetic drill, the drilling is more accurate and faster; and the unnecessary waste of labor power and time is reduced.
Description
Technical field
The invention belongs to trolley coach mounting technology field, be applicable to EDI project upper strata seat support installation procedure.
Background technology
In the EDI626 project, the upper strata seat support is installed needs to use the BOM pulling rivet of HUCK to be fixed on the upper floor, need to drill through nearly 144 of staking hole on the plane of whole upper floor, owing to require very strict to the aperture during staking of BOM nail, size in control Manual drilling aperture, the process aspects such as perpendicularity, the prior art situation is, by using magnetic drill or using the drill bit guiding module, but magnetic drill for this project when same plane needs to drill through a large amount of holes simultaneously, mobile inconvenient, although can well guarantee single hole quality, can not guarantee the distance between the Kong Yukong; Drill bit guiding module self can swing with drill bit, can not reach follow-up staking operation to the requirement in aperture through the test drilling effect.
Summary of the invention
The purpose of this invention is to provide the problem for the two objective upper strata seat support stakings of EDI that solve outlet Australia, for size and the perpendicularity that guarantees the staking hole reaches high-precision process program.
For achieving the above object, the invention provides a kind of seat support bore process method, it is characterized in that: add the guiding drill jig at whole positioning tool and hole, identical according to distance between per two row's seats, every row's seat is on the same straight line, subdrilling two row's bearing installing holes, after two row's bearings installation hole drills are complete, downwards along moving a round, the hole that Kong Yuyi on the whole positioning tool has been bored overlaps, and with alignment pin whole positioning tool is fixed on the hole of having bored, and drills through another round, successively along moving, to guarantee the relative position between every round.
Because it is very large that drilling quality is affected by drill bit, for this irreversible operation of staking certain risk arranged, and adopts pore-forming twice for avoiding this risk, and the poor 0.5mm of diameter of twice use drill bit, the drill bit Integrated Chip effectively avoided.
Whole positioning tool is on two tie-beams of general frame, is fixedly connected with the boring model according to the distance between two bearing installing holes of seat.
The present invention adopts the whole location of per two row's seat support installing holes, after two row's bearings installation hole drills are complete, along moving a round, the hole that the Kong Yuyi on the frock has been bored overlaps, and frock is fixed on the hole of having bored with alignment pin downwards, drill through another round, along moving, so just well guarantee the relative position between every round successively, effectively raised operating efficiency, than using magnetic drill one hole one to move accurately, fast a lot, reduce unnecessary manpower and waste of time.
Description of drawings
Fig. 1 is tool structure schematic diagram of the present invention;
Fig. 2 is seat support boring model structural representation.
The specific embodiment
With reference to Fig. 1, Fig. 2, implementation process of the present invention is as follows:
1, positioning tool: whole positioning tool is on two tie-beams 2 of general frame, is fixedly connected with boring model 1 according to the distance between two bearing installing holes of seat.Take wallboard as benchmark, the corresponding wallboard center, center of any round is loaded onto in recruitment, guarantees that the frock edge is identical far from wallboard face both sides.Adding the guiding drill jig at whole positioning tool holes, drill jig by with whole positioning tool interference fit, make drill jig firmly be positioned on the frock, drill through first four holes on the corner location on the frock, then with alignment pin by these four holes with tool locating on the floor, frock is mobile when guaranteeing to drill through rear face; Can effectively limit when boring during owing to artificial origin and Manual drilling drill bit certainty rock the aperture out of plumb phenomenon that causes.
2, behind the fixing tool, disposable the drilling through of four rounds on the frock finished, to note in the boring procedure, at first to make electric drill slowly finish stably a boring procedure, in time check drill bit after having bored a hole, timely cleaning Integrated Chip, timely bit change more in the overheated situation of drill bit avoids causing Integrated Chip.
3, drill through successively next round: along moving a round, the hole that the Kong Yuyi on the frock has been bored overlaps, and with alignment pin frock is fixed on the hole of having bored, and drills through another round downwards.Along moving, so just well guaranteed the relative position between every round successively.
4, cut floor cloth, secondary drilling, cut off rear secondary pore-forming according to the floor cloth that boring model profile will have been completed.
Claims (3)
1. seat support bore process method, it is characterized in that: add the guiding drill jig at whole positioning tool and hole, identical according to distance between per two row's seats, every row's seat is on the same straight line, subdrilling two row's bearing installing holes, after two row's bearings installation hole drills are complete, downwards along moving a round, the hole that Kong Yuyi on the whole positioning tool has been bored overlaps, whole positioning tool is fixed on the hole of having bored with alignment pin, drill through another round, successively along moving, to guarantee the relative position between every round.
2. seat support bore process method according to claim 1 is characterized in that: adopt pore-forming twice, and use the poor 0.5mm of diameter of drill bit for twice.
3. seat support bore process method according to claim 1 and 2, it is characterized in that: whole positioning tool is on two tie-beams of general frame, is fixedly connected with the boring model according to the distance between two bearing installing holes of seat.
