Keywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.

Background technology
The drilling in a plurality of holes processing mainly contains dual mode on the plane: a kind of is to use common driller, and by the bushing plate guiding, the position in a plurality of holes is carried out drilling processing one by one on the corresponding bushing plate, and the processing of this kind method takes time and effort, and working (machining) efficiency is low, low precision; Another kind is to be finished by Digit Control Machine Tool, and this kind processing method precision is high, but the lathe cost is higher, and the action required personnel qualifications is high.
Summary of the invention
The purpose of this utility model is to provide a kind of crankshaft end-face flange hole multiaxis drilling special plane, and a plurality of drill bits of primary feed are finished the boring of crankshaft end-face porous simultaneously, cuts down finished cost, and improves machining accuracy and working (machining) efficiency.
The utility model is achieved by the following technical programs:
A kind of crankshaft end face multi-drill is cut special plane, comprise base, be separately positioned on the feed system of base one end and the drilling system of the base other end, described feed system comprises Hydraulic Station, oil cylinder, drilling jig tool and slide unit, described slide unit comprises slide unit base, slide unit body, described slide unit base is fixed on base one end, the slide unit body is inlaid on the slide unit base, drilling jig tool is fixed on the slide unit, the oil pipe at oil cylinder two ends is connected with Hydraulic Station, oil cylinder one end is fixedly connected with slide unit base one end, and cylinder piston rod termination and slide unit body one end are hinged; Described drilling system is arranged on the other end of base, comprise unit head, gear-box and motor, motor is fixed on the base other end, be connected with the unit head input by driving-belt, unit head is connected with gear-box, and the handle of a knife that many output shafts of gear-box pass through separately respectively links to each other with the drill bit rear end.
The purpose of this utility model can also further realize by the following technical programs.
Aforesaid crankshaft end face multi-drill is cut special plane, wherein said drilling jig tool comprises base plate, riser, axial location axle, bushing plate and two V-type back-up blocks, described riser is vertically fixed on base plate one end, bushing plate is vertically fixed on the base plate other end relative with a plurality of drill bits, two V-type back-up blocks are between riser and bushing plate, on the base plate that is vertically fixed on respectively; Axial location axle one end passes riser, is connected with riser by screw thread.
The utility model is processed a plurality of thread Pilot holes of crankshaft end-face that the location is clamped on the drilling jig tool simultaneously by being arranged on the much knives tool on the gear-box, has greatly improved working (machining) efficiency.The relative position in each hole is determined by the relative position between the many output shafts of gear-box, as long as guarantee the positional precision of many output shafts, just can guarantee the relative position in a plurality of holes of crankshaft end-face, thereby guarantee each hole location.The relatively processing of the one by one single hole of prior art, machining accuracy of the present utility model improves a lot.The utility model has realized that a plurality of thread Pilot holes of crankshaft end-face process automatically, can reduce artificial intensity, saves a large amount of manpowers, has reduced processing cost.The utility model utilizes on the bushing plate guiding of locating hole to process, and has strengthened the rigidity of boring, and simple to operate, machining accuracy is high.
Advantage and disadvantage of the present utility model will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example with reference to accompanying drawing.
