Description

Two drill bit horizontal drilling machines
Technical field
The utility model relates to a kind of drilling machine, relates to particularly once and can bore the drilling machine in two holes simultaneously.
Background technology
In mechanical processing process, the product that needs to bore a plurality of holes in same plane is very common, also has such special equipment at present, for example, the both sides of engine cylinder cover are respectively provided with two mail gallery holes, in prior art, the mail gallery holes of engine cylinder cover all adopts CNC lathe to process, and the problem of its existence is, drill bit is long, beat large, easily bore partially, often breaking of rod head.The time of the above-mentioned operation of CNC machine tooling is long, generally needs within 31 minutes, just can complete, and belongs to the bottleneck operation in process, cannot meet Production requirement, and CNC lathe cost is high in addition, and every CNC lathe expense is about 500,000 yuan, business burden weight.
Utility model content
The utility model, according to above not enough, provides a kind of pair of drill bit horizontal drilling machine, can bore two holes simultaneously, also can be for the processing of the mail gallery holes of engine cylinder cover.
The technical solution of the utility model is:
A drill bit horizontal drilling machine, comprising:
Frame, is arranged with at least two guide rails in parallel;
Base plate, its below be fixed with feed screw nut and with the supporting slide block of described guide rail;
Transmission case, is arranged on the top of base plate, and transmission case is provided with two power transmission shafts, and one end of this power transmission shaft is fixed with drive, and the other end is fixed with the drill chuck for clamping drilling bit;
Motor, is fixed on the top of transmission case, and the driving wheel on machine shaft is taken turns by driving-belt joint transmission, and electric machine rotation drives drill bit to rotate;
Stepper motor, is fixed in described frame, and the rotating shaft of stepper motor connects with screw mandrel, and screw mandrel coordinates with feed screw nut, and stepper motor rotates and drives base plate to move along guide rail, finally drives drill bit to move axially.
It should be noted that, workpiece can be fixed in frame of the present utility model by workpiece holder, also can be fixed in special-purpose frame, this special-purpose frame can be the part on streamline, and workpiece fixing on streamline passes to next process after the utility model boring.
Described motor is fixed on motor fixing plate, and motor fixing plate one end is hinged on the edge of described transmission case, and another edge and the screw of transmission case are hinged, and the other end of motor fixing plate is fastened by two nut clip through screw.
By regulating the angle of motor fixing plate and transmission case can regulate the degree of tightness of driving-belt.
The utlity model has beneficial effect simple in structure, that cost is low, machining accuracy is high, easy to process, process time is short, operating efficiency is high.
