Abstract

The utility model discloses a high-efficient handle drilling machine, and aims to provide a high-efficient handle drilling machine which can increase position precision of processing holes and processing efficiency and can avoid drilling oversize. The high-efficient handle drilling machine comprises a latch and a drilling die plate with a handle, a positioning pin with shape and size identical to those of a center hole of a to-be-processed part is arranged on a plane below the drilling die plate, and two sides of the positioning pin are provided with guide holes with pitches and sizes identical to the pitch and the size of the to-be-processed part. Compared with the prior art utilizing a manual marking positioning and eyeballing drill processing method, the high-efficient handle drilling machine is accurate and reliable in positioning, high in position precision, extremely high in processing yield and low in oversize rate, is convenient and fast, can be doubled in processing efficiency and greatly reduces cost of production and work time, and further, a drill bit of the drilling machine is not easy to deflect like drilling on a flat plate.

Description

Efficient handle drill

Technical field

The utility model relates to a kind of location drilling frock, and in particular, the utility model relates to a kind of efficient handle drill.

Background technology

In the prior art, on the same plane of a processing parts, to process often based on the fixing two side holes of a central hole location.This is 3 lines of the centre of location or the machining hole in 3 planes with the centre bore, and the processing method that the workman is traditional is by the centre bore that processes, line location earlier, and the heart position, hole in hole to be processed, both sides is determined in artificial line.Use the hole instrument then, rely on the artificial visually examine, align line axle center, hole and hole.This weak point to the unconfined bore mode of processing drill bit is, the easy sideslip of drill bit, and the pitch-row positional precision is poor, and secondly aperture overproof rate height is that efficient is low.Especially the processing in a large amount of holes to be processed of the same type on the wall panel parts, its low drilling efficiency is very obvious.

Summary of the invention

The purpose of this utility model is at above-mentioned the deficiencies in the prior art part, propose a kind ofly can improve machining hole positional precision and working (machining) efficiency, and it is overproof to avoid holing, and improves the efficient handle drill of qualification rate.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of efficient handle drill, comprise, a latch, it is characterized in that, it comprises that also has a little bushing plate that upwarps handle, on the lower, planar of this described bushing plate, be shaped on and part center hole shape to be processed, alignment pin of the same size, be shaped in the both sides of described alignment pin consistent with the pitch-row of part to be processed, and the identical pilot hole of size.

The utility model is than above-mentioned artificial line location, the prior art of range estimation boring processing, it is reliable to have an accurate positioning, positional precision height, drill bit can be as brill on flat board easy sideslip, passing rate of processing is high, overproof rate is little.Convenient and swift, working (machining) efficiency significantly improves, and produces time cost and significantly reduces.Through assemble a large amount of holes of wallboard part at aircrafts such as A320, A340 B747 B787 DS, hundreds of different size mesopore processing proof, compare traditional line processing, processing a hole can save 5 minutes, accumulative total is processed this type of hole more than 10,000, can save the above work time cost of thousands of man-hours and tens thousand of unit.。

Fig. 1 is the efficient handle drill of a utility model decomposing schematic representation.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is that the A-A of Fig. 2 is to cutaway view.

Fig. 4 is the embodiment schematic diagram that the utility model is embedded in steady pin bushing plate one side.

The specific embodiment

Consult Fig. 1～Fig. 3.On the lower, planar that has little bushing plate 1 that upwarps handle 5, be shaped on one with part center hole shape to be processed, alignment pin of the same size 3.Be shaped in the both sides of described alignment pin consistent with the pitch-row of part to be processed, and the identical pilot hole of size.The position of two pilot holes of alignment pin 3 and both sides just in time coincides with the pitch-row center in part hole to be processed.Two pilot holes can be set with the high and wear-resisting guide hole lining 2 by hardness, and as the guide hole that guides drill bit.The aperture of guide hole lining 2 is consistent with part preprocessing aperture nominal dimension.Bushing plate 1 alignment pin 3 diameters are consistent with the center-hole diameter on the part, and it is as positioning guide column to add man-hour.During boring, the workman grasps the handle 5 of perk, and at first the alignment pin 3 with bushing plate 1 below is embedded in the centre bore of part to be processed, then drill bit is put into 2 one guide holes of guide hole lining and is holed, and drill bit is directly put into boring.After processing a side workpiece hole, latch 4 is inserted in this hole, bushing plate 1 firmly is positioned on the plane of processing parts exactly, at this moment, drill bit is put into the guiding guide hole lining 2 of bushing plate 1 opposite side.

With bushing plate when boring finding, the handle 5 that upwarps that links to each other with bushing plate 1 can the zero degree flat board, the bushing plate material can select hardness to be higher than the material of drill bit, can be without inlay busher, direct by the guiding hole drill system machining hole on the relevant position on the bushing plate.

Working position is during with respect to the two side holes of centre bore symmetry, latch 4 can be changed into the side that steady pin shown in Figure 4 is embedded in bushing plate 1, be that centralized positioning pin 3 and latch 4 protrude from the guide pillar steady pin on the bushing plate 1 same plane, bore a hole, with bushing plate 1 turn-over, another hole is bored in the hole that centrepin and guide pillar steady pin insert centre bore respectively and just processed again.The utility model can be processing and three hole workpieces of alignment pin 3 conllinear, also can be isoplanar non-equidistant with alignment pin 3,3 three hole workpieces of conllinear not.
