Abstract

A centre drilling machine tool comprises a horizontal workbench, wherein a drive clamp assembly and a driven clamp assembly are respectively arranged at the middle part of the horizontal workbench, a fixed tailstock assembly and an adjustable movable tailstock assembly are respectively arranged at the two sides of the horizontal workbench, a left-handed rotation centre drill is assembled on the fixed tailstock assembly, a right-handed rotation centre drill is assembled on the adjustable movable tailstock assembly, air cylinders are respectively fixed at the rear parts of the fixed tailstock assembly and the adjustable movable tailstock assembly, a linear guide rail assembly is arranged between the upper body of the adjustable movable tailstock assembly and a base, and a location oil cylinder is fixed at one side of the drive clamp assembly on the horizontal workbench. According to the centre drilling machine tool, the deviated centre drilling phenomenon can be prevented from occurring; and meanwhile, an adjustable clamping drive device is adopted, so the centre drilling machine tool can be suitable to drill centre holes for shafts of different lengths.

Description

A kind of centre-drilling hole lathe

Technical field

The utility model relates to a kind of Machining of Shaft-type Parts device, especially a kind of centre-drilling hole lathe that is applicable to many kinds axial workpiece.

Background technology:

At present, known axial workpiece drill centers lathe generally is that axle spare is clamped, and the axle part does not rotate; The two ends unit head drives the centre drill rotation and moves axially feeding, realizes drill centers.But this axle part clamps not rotation mode drill centers, and is higher to axle spare blank Geometrical Tolerance Principle, because the axle part clamps do not rotate, and observes not undesirable phenomenon of shaft spare blank form and position tolerance and the incorrect phenomenon of clamping behind the clamping.As the blank of semiaxis class, be hot forging; The forge hot half-shaft blank of especially flanged dish, aspect form and position tolerance: linearity and ring flange end face like bar portion jump to, and all have the lower phenomenon of precision; Promptly not reaching 100% meets the requirements; The inclined to one side problem of centre drill then can appear in the drill centers lathe drill centers with general, part processing of influence axle or occurrence of waste.

Summary of the invention:

For overcoming the defective that above-mentioned prior art exists; The utility model provides a kind of centre-drilling hole lathe, and the adjustable driving clamping device of these machine adopted two covers clamps the rotation of rear drive shaft spare to the axle part; Both sides are adopted left-handed respectively and the dextrorotation centre drill, promote the centre drill drill centers with cylinder.This covering device not only can observe a part form and position tolerance whether qualified, avoid processing defective work, can also adapt to different length the axle part.

The technical scheme that adopts:

A kind of centre-drilling hole lathe; Comprise that horizontal table laterally is provided with location T type groove on the horizontal table; Be respectively equipped with initiatively anchor clamps assembly and passive anchor clamps assembly at the horizontal table middle part; Be respectively arranged with fixedly tailstock assembly and adjustable mobile tailstock assembly in the both sides of horizontal table, fixedly on the tailstock assembly left-handed centre drill be housed, be equiped with the dextrorotation centre drill on the adjustable mobile tailstock assembly; Fixedly the rear portion of tailstock assembly and adjustable mobile tailstock assembly is fixed with a cylinder respectively; Between adjustable mobile tailstock assembly upper body and base, be provided with the line slideway assembly, on horizontal table, be positioned at active anchor clamps assembly one side and be fixed with a location oil cylinder, the front end of positional cylinder piston is equiped with locating piece; A side that on horizontal table, is positioned at adjustable mobile tailstock assembly is fixed with one and vertically spurs oil cylinder; Vertically piston and the adjustable mobile tailstock assembly upper body of pulling oil cylinder are hinged, initiatively are equiped with a drive motors on the anchor clamps assembly, and the belt pulley of installing on the drive motors power output shaft is connected with belt pulley on the active anchor clamps assembly through belt.

The beneficial effect of the utility model is: when behind axle spare clamping, rotating, whether whether can observe a part clamping correct qualified with axle part form and position tolerance, avoid occurring the inclined to one side phenomenon of centre drill; Adopt adjustable driving clamping device simultaneously, can adapt to the axle part drill centers of different length.

The specific embodiment

A kind of centre-drilling hole lathe; Comprise; Horizontal table 5 laterally is provided with location T type groove on the horizontal table 5, be respectively equipped with initiatively anchor clamps assembly 4 and passive anchor clamps assembly 3 at horizontal table 5 middle parts; Be respectively arranged with fixedly tailstock assembly 7 and adjustable mobile tailstock assembly 1 in the both sides of horizontal table 5; Left-handed centre drill 6 fixedly is housed on the tailstock assembly 7, is equiped with dextrorotation centre drill 2 on the adjustable mobile tailstock assembly, fixedly the rear portion of tailstock assembly 7 and adjustable mobile tailstock assembly 1 is fixed with cylinder 13,9 respectively; Fixedly tailstock assembly 7 laterally moves through cylinder 13,9 with adjustable mobile tailstock assembly 1; Between adjustable mobile tailstock assembly 1 upper body and base, be provided with line slideway assembly 11, be used to adjust the distance of dextrorotation centre drill 2 relative workpiece, on horizontal table 5, being positioned at initiatively, a side of anchor clamps assembly 4 is fixed with a location oil cylinder 15; The front end of positional cylinder 15 pistons is equiped with locating piece 16; A side that on horizontal table 5, is positioned at adjustable mobile tailstock assembly 1 is fixed with a vertical pulling oil cylinder 10, and the piston that vertically spurs oil cylinder 10 is hinged with the upper body of adjustable mobile tailstock assembly 1, is equiped with a drive motors 12 on the active anchor clamps assembly 4; The belt of installing on drive motors 12 power output shafts 17 is taken turns 8 and is connected with belt pulley 17 on the anchor clamps assembly 4 initiatively through belt, and the middle part of horizontal table 5 is equipped with push-botton operation dish 14.

Job step:

Control cylinder 15 promotes locating pieces 16 and vertically enters anchor point, the adjustable mobile tailstock assembly of cylinder 10 pullings 1 upper body and vertically fall back on initial point → axle spare is packed into from passive anchor clamps assembly 3 end cross, vertically falls back on initial point, vertically spurs oil cylinder 10 and promote adjustable mobile tailstock assembly 1 upper body and vertically enter central task point → startups drive motors 12 driving shaft spares rotation (whether observe the axle part normal) → cylinder 13 and cylinder 9 and promote the left-handed centre drill of left-handed centre drill 6, dextrorotation centre drill 2 traverse feed drill centers → cylinders 13 and cylinder 9 pullings 6, dextrorotation centre drill 2 and laterally return to initial point → close motor → manually unclamp anchor clamps, take out a part up to running into the clamp shaft spare → control cylinder 15 pulling locating pieces 16 of locating piece → manually.
