Abstract
The invention discloses a deep-hole drilling jig for processing deep holes. Two drilling jig plates and a drilling jig body are positioned by positioning pins; a workpiece is arranged in the drilling jig body and between the two drilling jig plates and is pressed by a pressing screw; and the two drilling jig plates are internally and respectively provided with a drilling sleeve I and a drilling sleeve II which are concentric. The deep-hole drilling jig adopts a method of oppositely drilling at two ends to process the deep holes, and since holes concentrically drilled by the two drilling sleeves are not easy to deviate, are high in concentricity are not subjected to limitation of equipment, and the processing of the deep holes can be realized on any drilling machine; the drilling jig can be designed and manufactured according to the shape of the workpiece, and is simple in structure and low in cost; and a lengthened twist drill can not be adopted, chip removal is easy, the fracture of a drilling bit is effectively prevented, the processing cost is reduced and the hole drilling efficiency is high.
Description
Technical field
The present invention relates to the Machining Technology field, is a kind of deep hole drill jig that is used for drilling deep hole specifically.
Background technology
At present, the workpiece drilling deep hole adopts lengthening fluted drill and drill gun
usually.During with lengthening fluted drill drilling deep hole, workpiece is put on the drilling machine, starts drilling machine; Shake handle and make the lengthening spiral bit downfeed; The hole drill of workpiece is logical, and have following defective: 1, the purchase cost of lengthening fluted drill is high, and a lengthening fluted drill needs 500～1000 yuan; 2, chip removal difficulty, chip removal often, efficient is low, drilling time is long; 3, chip removal is not thorough, and iron filings block the lengthening fluted drill easily, makes the fried dough twist drill chuck disconnected, and the fluted drill that breaks in workpiece hole is difficult to take out, and workpiece also can only be scrapped, and use cost is high.During with the drill gun drilling deep hole, workpiece is put on the drilling machine, starts the drilling machine rotating disc; Driving workpiece is center of circle rotation with the deep hole center line, shakes handle drill gun is downfeed holed, simultaneously; Add cooling fluid through the drill gun centre bore to machined surface, play and force cooling and force the chip removal effect, until hole drill is logical; Have following defective: 1, cost is high, and a drill gun is wanted 4～5,000 yuan; When 2, holing with drill gun, drill gun does not rotate, and workpiece changes, and most of equipment can't use, and must use special plane, and equipment limitation is big.
Summary of the invention
For overcoming the deficiency of prior art, goal of the invention of the present invention is to provide a kind of deep hole drill jig, not limited to by equipment, with convenient and swift drilling deep hole, realizes reducing cost and improves the purpose of working (machining) efficiency.
Be to realize above-mentioned purpose, two bushing plates of the present invention are through alignment pin and model drilling body location, and workpiece is contained in the model drilling body, between two bushing plates, compress with clamping screw, and it is concentric to be respectively equipped with drill bushing one and two, two drill bushings of drill bushing in two bushing plates.
The present invention compared with prior art has the following advantages:
1, adopt the method deep hole processing of two to boring, because two drill bushings are concentric, the hole that gets out is difficult for sideslip;
2, do not need rotating disc, do not receive device-restrictive, on any drilling machine, all can realize the processing of deep hole;
3, drill jig can be according to workpiece shaped design and manufacturing, and is simple in structure, at the bottom of the cost;
3, simultaneously, can not adopt the lengthening fluted drill, chip removal is easy, can effectively prevent the drill bit fracture, cuts down finished cost, and drilling efficiency is high.
Description of drawings
Accompanying drawing is a structure diagram of the present invention.
The specific embodiment
Shown in accompanying drawing, the present invention is made up of four alignment pins 1, two bushing plates 2, clamping screw 3, drill bushing 1, drill bushing 28, a model drilling body 5.Stud with drill bushing 1 and drill bushing 28 in two bushing plates 2 respectively, bushing plate 2 is positioned at model drilling body 5 through four alignment pins 1, and workpiece 6 is contained in the model drilling body 5, between two bushing plates 2, compress with clamping screw 3, and drill bushing 1 is concentric with drill bushing 28.
During boring, workpiece 6 is put into model drilling body 5, model drilling body 5 is clamped, insert four alignment pins 1 with two bushing plates 2; Tighten clamping screw 3, drill jig is put on the drilling machine, drill bushing 1 starts drilling machine up; Shake handle and make spiral bit 9 downfeed, through drill bushing 1 boring, when hole drill to a half withdrawing; Upset drill jig, drill bushing 28 repeat said process deep hole 7 are drilled through up.
