Be provided with lining and following lining between described axle sleeve outer sleeve and the screw mandrel overcoat.
The drilling method of this steering wheel pedestal boring that proposes according to above technical scheme, comparing with the processing method that now traditional hand-held pneumatic drilling machine carries out bore operation has the following advantages:
1, owing to carry out in the process in processing at the axle sleeve center and the steering wheel center of screw mandrel formula driving and reversing mechanism
All the time be under constant spacing and the parastate, therefore, be connected with frock under the firm condition, guarantee in the whole air drill rotation process that the centre of gyration of drill bit is stable at the air drill afterbody, can not produce the swing that hand-held operation produces afterbody like that, thereby provide technical guarantee for improving drilling quality.
2,, and rely on feed wheel to rotate the stable centripetal force that produces because the reliable location of frock,
It is firm that boring procedure is stablized more, overcome the rotating interrupted phenomenon of cutter that traditional artificial hand held drilling causes because of unstable centripetal force, therefore has higher feeding efficient.
3, reduce working strength of workers greatly, improve the security of operation.
4, overcome under the narrow cabin because of adopting under the traditional diamond-making technique near the boring of bulkhead position
Difficulty, it is more convenient that the workman is operated.

The specific embodiment
The drilling method of this steering wheel pedestal boring, with the steering wheel top center as initial point, being provided with one is the pivoted arm auxiliary clamp 15 at center with this initial point, and in the outer end of described auxiliary clamp 15 an affixed drilling tool of forming by screw mandrel formula driving and reversing mechanism A and hand-held air drill 12, realize the drilling of each boring one by one according to the position of setting, hole, around steering wheel 14 outer rings.
Described pivoted arm auxiliary clamp 15 is made up of a connecting rod 15.1, right angle rack 15.3 and anchor ear 16, the right-angle side of described connecting rod 15.1 and right angle rack 15.3 is integral through attachment screw is affixed, and the anchor ear 16 of one level to banding is set at the connecting-rod head that is connected with described right angle rack 15.3, on the body of rod of described connecting rod 15.1, be provided with a connecting hole and the nut 15.2 that is used to be connected the steering wheel center origin simultaneously.
Described screw mandrel formula driving and reversing mechanism A comprises feeding handwheel 1, feed screw 9, screw mandrel overcoat 2, abutment sleeve 3, axle sleeve outer sleeve 6, adapter sleeve 7, feed screw 9 wherein is set in the screw mandrel overcoat 2 and with the one section screw mandrel that is arranged on screw mandrel overcoat 2 inner chambers and advances cover 10 to be spirally connected, and forms the screw mandrel push structure; Simultaneously, the upper end of described feed screw 9 is affixed through connecting key and feeding handwheel 1, and is connected with abutment sleeve 3 outside being placed in screw mandrel overcoat 2 through attachment screw and the top cover 11 of being located at feeding handwheel bottom; The bottom of described abutment sleeve 3 is provided with the axle sleeve outer sleeve 6 that an end connects through attachment screw 4, and described outer sleeve 6 is connected with screw mandrel overcoat 2 to the dog screw that is provided with through level again; In addition, screw mandrel overcoat 2 inner chambers in described feed screw 9 bottoms are provided with an adapter sleeve 7 that can advance downwards in cavity.
Be provided with lining 8 and following lining 5 between described axle sleeve outer sleeve 6 and the screw mandrel overcoat.
The operation principle of the drilling method of this steering wheel pedestal boring is as follows:
The pivoted arm anchor clamps that utilization is made of right angle rack 15.3 and connecting rod 15.1, and straight by being arranged on
Subsequently, by install hand-held air drill 12 at the adapter sleeve 7 of the bottom of screw mandrel formula driving and reversing mechanism A, form the drilling method of steering wheel pedestal boring that can easy operation at this point.In the time will handing the drill bit boring point of air drill 12 bottoms, along with the brill of hand-held air drill 12 is moving, the operator needs only swivel feeding handwheel 1 easily, the feed screw 9 that is connected with feeding handwheel 1 will advance downwards under the effect of the screw mandrel propelling cover 10 that is arranged at screw mandrel overcoat 2 inner chambers, apply feed pressure for the hand-held air drill 12 in the running, finish the drilling task of a boring until hand-held air drill 12.After the drilling task for the treatment of this boring is finished, as long as reverse rotation feeding handwheel 1, feed screw 9 is carried under the acting in conjunction of screw mandrel propelling cover 10, return to the home position, just can withdraw from from the boring that has become handing air drill 12 this moment, and be the axle center, be displaced to next boring point and carry out a next drilling of holing with steering wheel 14 central upper portion point with whole screw mandrel formula driving and reversing mechanism A.And the like can finish the drilling of all borings on the whole steering wheel very goodly.
Show that through the reality use employing of this technology can bring following economic benefit:
1, improves penetration rate, shortened steering wheel installation period
By each hole drill cut save the man-hour=former drilling man-hour (1.2 hours)-existing drilling man-hour (0.5 hour), each boring can save time 0.7 hour.
Every ship drilling save the man-hour=each hole drill cut save the man-hour * steering wheel hole number (by 10 holes), each bar ship is saved 7 hours drilling time.
Save 2 hours unproductive times.
Saved labor hour 18 hours.
2, improved the quality of drawbore, for the fine finishining in hole provides assurance
Adopt the ovality＞1mm of conventional art drawbore, adopt the ovality≤0.3mm of this device back drawbore, the surface quality of processing metapore originally is very low, the time generation of step phenomenon arranged; Eliminated this type of phenomenon after adopting this device, for follow-up fraising has improved the processing quality assurance.
3, reduce operator's labour intensity, improved production security
The workman need not to rely on all the time in boring procedure manpower directly to apply centripetal force, and only need rotate handwheel, and labour intensity obviously greatly reduces; And the workman so Labor Safety also obviously improves, more meets the theory of green shipbuilding because do not need hand-held all the time air drill to overcome the moment of torsion of generation.
