Abstract
The utility model relates to a special machine tool for machining engine crankshaft oil duct holes. The machine tool is mainly designed to solve the problems that the labor intensity is great, etc. as radial drills are manually used to drill holes at present. The machine tool comprises a body, wherein workbenches are arranged above linear guideways on the body; bearing bush seats are arranged on the workbenches; sliders are connected with the linear guideways in a sliding manner; one ends of pressure plates on the workbenches are connected with rods of cylinders; the pressure plates are connected with connection plates; the connection plates are connected with the bearing bush seats by small shafts; positioning sleeves are arranged on fixed seats on the body; positioning pins in the positioning sleeves are connected with wrenches; positioning blocks are connected with T-shaped grooves on the workbenches fixedly; positioning guide keys on fixed plates are matched with key grooves on the body; handwheels are installed on the fixed plates; gears are arranged on the handwheels; racks on the workbenches are meshed with the gears on the handwheels; power head adjusting seats are fixedly connected with the fixed plates; power heads are arranged on rotary connection supports on the power head adjusting seats; and drill bits are installed on the power heads. The machine tool has the advantage of low labor intensity.
Description
Technical field:
The utility model relates to a kind of special purpose machine tool of processing the engine crankshaft oil hole.
Background technology:
At present, producing engine crankshaft when the machining crankshafts oil hole, all is manually to hole with radial drill, and shortcoming is: labour intensity is large, and effect is low, and speed is slow, and a workman can only process 30 six-cylinder crankshafts in 8 hours.
Summary of the invention:
It is high that technical problem to be solved in the utility model provides a kind of effect, and penetration rate is fast, the special purpose machine tool of the processing engine crankshaft oil hole that crudy is good.
Above-mentioned purpose is achieved in that it comprises lathe bed, line slideway is arranged on the lathe bed, there is workbench the line slideway top, be fixed with bush seat on the workbench, have the line slideway on slide block and the lathe bed to be slidingly connected below the workbench, pressing plate is arranged on the workbench, one end of pressing plate is connected with the cylinder bar of cylinder by little axle, cylinder is fixed on the workbench, and the middle part of pressing plate is connected with connecting plate by little axle, and connecting plate is connected with bush seat with little axle;
Holder is fixed by bolts on the lathe bed, positioning sleeve is fixed on the holder, alignment pin is arranged in the positioning sleeve, spanner is contained on the positioning sleeve by axle, one end of spanner and an end of alignment pin are slidingly connected, and the other end of alignment pin matches with fixing hole on the locating piece, plays the role of positioning, locating piece is connected and fixed with the T-shaped groove on bolt and the workbench, can move axially;
The positioning and guiding key is housed on the fixed head, keyway is arranged on the lathe bed, positioning and guiding key on the fixed head matches with the keyway on the lathe bed, fixed head can move axially, handwheel is contained on the fixed head, gear is housed on the handwheel, workbench is equipped with tooth bar on the position corresponding with handwheel on the fixed head, the engagement of gear on the handwheel and the tooth bar on the workbench has vertical positioning and guiding groove on the fixed head, the boss that matches with positioning and guiding groove on the fixed head is arranged on the unit head adjusting seat, unit head adjusting seat and fixed head are joined with bolts, on the unit head adjusting seat switching support is arranged, unit head is contained on the switching support and with bolt and fixes, and drill bit is contained on the unit head.
The course of work and advantage: the control button of pressing first the cylinder of control pressing plate, make pressing plate lift, bent axle is put on the bush seat, presses again the dynamic air cylinder button, with pressing plate bent axle is compressed, shake handwheel, bent axle on the workbench is transferred to the position that will process, alignment pin is inserted in the fixing hole, unit head work, bore oil hole, be worked into size after drill bit will automatically withdraw from (itself carries limit switch unit head).Advantage is that labour intensity is little, and effect is high, and speed is fast, and quality is good, and a people can process 80 six-cylinder crankshafts in 8 hours.
