Abstract
The invention provides a fixture for a numerically controlled lathe rotary turret and relates to the technical field of mechanical manufacture. The fixture is pressed tightly in a turret tool groove by a first numerically controlled lathe turret screw; the fixture is internally provided with a V-shaped groove; a straight shank drill is pressed tightly in the V-shaped groove in the fixture by a second screw; the fixture can be internally provided with a taper hole in which a taper shank drill is installed; the fixture is fixed in the numerically controlled lathe turret; an adjusting gasket is arranged between the bottom surface of the fixture and the turret. The upper surface of the fixture can be provided with a V-shaped groove. Based on the full utilization of numerically controlled lathe resources, the fixture is installed on a four-station rotary turret of a numerically controlled lathe and the straight shank drill or the taper shank drill are installed in the V-shaped face or the taper hole in the fixture; the central position of the straight shank drill or the taper shank drill can be located rapidly; the center height or the small carrier plate value requires no adjustment; by changing different straight shank drills or taper shank drills, the tool positions are switched rapidly, so that the production quality is improved; the turning and drilling can be switched, so that the whole work piece machining is automatic.
Description
Technical field
The present invention relates to machinery manufacturing technology field, specifically a kind of fixture for numerically controlled lathe circular cutter holder.
Background technology
Existing centre numerically controlled lathe four station circular cutter holder, when the simple workpiece of some profiles of turning, often occur that cutter spacing is left unused, and the centre bore of workpiece, through hole or screwed hole need to add man-hour, the handle at rotation number control lathe tailstock rear portion and change centre drill and drill bit, all need manual operation, labour intensity is large, inefficiency.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of fixture for numerically controlled lathe circular cutter holder, to improve working (machining) efficiency, reduces operator's labour intensity.
For achieving the above object, fixture of the present invention is pressed in the cutter groove of knife rest by the screw one of Tool-rest of Numerical Control Lathe, and the inside of fixture is with V-type groove, and straight shank drill is pressed in the V-type groove of fixture inside by the screw two of fixture.
Described fixture inside also can with taper hole, and taper-shank drill is arranged in the taper hole in fixture.
Described fixture is fixed in Tool-rest of Numerical Control Lathe, is provided with adjustment pad between the bottom surface of fixture and knife rest, and the upper surface of fixture also can with V-shaped groove.
The angle [alpha] of described V-shaped groove is 0 ° of < α < 180 °.
The present invention compared with prior art, make full use of the resource of numerically controlled lathe, sectional fixture on four station circular cutter holders of centre numerically controlled lathe, in V-type face straight shank drill or taper-shank drill being arranged on fixture inside or taper hole, can the center of quick position straight shank drill or taper-shank drill, high or the little supporting plate value in its center is without the need to adjustment, by changing different straight shank drills or taper-shank drill, carry out cutter spacing switching fast, to ensure the quality of product, and between turning and drilling, the automation of whole work pieces process can be realized.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
Fig. 2 is the structure diagram of another structure of the present invention.
Fig. 3 is the structure diagram of the fixture of Fig. 2.
Fig. 4 is the structure diagram of the another structure of the present invention.
Detailed description of the invention
As shown in Figure 1, fixture 4 is pressed in the cutter groove of knife rest 1 by the screw 1 of Tool-rest of Numerical Control Lathe 1, and straight shank drill 3 is pressed in the V-type groove of fixture 4 inside by the screw 25 of fixture 4, center height H and the numerically controlled lathe workpiece centre of gyration in the V-type face of fixture 4 join work, the center height H in V-type face is the size of V-type fixture VXing Mian center to bottom surface, center height when working to make straight shank drill 3 meets the requirement of processing, change different-diameter straight shank drill 3, center height H is without the need to adjustment, the angle [alpha] of the V-shaped groove of fixture 4, can manufacture and design according to the size of actual straight shank drill 3, the angle [alpha] of V-shaped groove is 0 ° of < α < 180 °.When holing to workpiece, as long as the position, little pallets level direction of adjustment numerically controlled lathe, overlap with the centre of gyration of workpiece, center height does not need adjustment.
As shown in Figure 2 and Figure 3, fixture 4 is pressed in the cutter groove of knife rest 1 by the screw 1 of Tool-rest of Numerical Control Lathe 1, the endoporus of fixture 4 is with Morse's taper, taper-shank drill 6 is arranged in the taper hole of fixture 4 inside, the Morse's taper center height H of fixture 4 joins work with the numerically controlled lathe installed, and center height when working to make taper-shank drill 6 meets the requirement of processing.After installing first, the little supporting plate value of adjustment numerically controlled lathe, taper-shank drill 6 overlaps with the centre of gyration of workpiece.When workpiece is holed, change the taper-shank drill 6 of different-diameter, without the need to adjusting the little supporting plate value of numerically controlled lathe, taper-shank drill 6 overlaps with the centre of gyration of workpiece, center height also without the need to adjustment because it is self centering that taper-shank drill 6 coordinates with the taper hole of fixture 4 inside.Meanwhile, taper-shank drill 6 can be the drill chuck of band taper shank, and the drill chuck of band taper shank can be arranged in the taper hole of fixture 4 inside, and band taper-shank drillchuck can clamp straight shank drill and use, and makes the scope of application of this fixture larger.The Morse's taper of fixture 4 taper hole can according to the installing space of different taper-shank drills 6 and numerically-controlled machine tool rest, designs different Morse's taper number (also can be other can the tapering of self-locking), to meet different instructions for uses.
As shown in Figure 4, the upper surface of fixture 4 is with V-shaped groove, straight shank drill 3 is pressed in the V-shaped groove of fixture 4 by the screw 1 of Tool-rest of Numerical Control Lathe 1, and between the bottom surface of fixture 4 from knife rest 1, be provided with different adjustment pads 7, for compensating the straight shank drill 3 changing different-diameter, center height when working to make straight shank drill 3 meets the requirement of processing.When workpiece is holed, as long as the little supporting plate place value in the horizontal direction of adjustment numerically controlled lathe, overlap with the centre of gyration of workpiece.The angle [alpha] of the V-shaped groove of fixture 4, can manufacture and design according to the size of actual straight shank drill 3, and the angle [alpha] of V-shaped groove is 0 ° of < α < 180 °.
