Description
Technical field
The utility model relates to numerically controlled lathe, particularly relates to a kind of numerically controlled lathe fixture.
Background technology
Numerically controlled lathe is widely used in bearing industry, can be used for soft car or hard car, no matter soft car or hard car, distortion during Workpiece clamping is the most formidable current difficult problem, and bearing enclose belongs to circular part, and the universal fixturing holding ring profile shaft bearing ring of numerically controlled lathe must cause lasso to be out of shape, cause the circular deviation of processing work overproof, although the precision of numerically controlled lathe is very high, because the reason of fixture, be difficult to process high-precision product.
In order to overcome the problems referred to above, technology has now been had to propose a kind of digital control lathe clamper, this fixture is moving forward and backward by collet, by the taper-face contact on the conical surface of collet and conical sleeve time mobile, swell or reduce, and then clamping ring-shaped work pieces, even if clamping force is excessive, also can be cancelled under the effect of the conical surface of collet; Although this fixture effectively overcomes above-mentioned technical problem, but this fixture is that whole fixture is all in rotation at work, after working long hours, because the fuselage produced when work pieces process trembles, the fixing appearance of fixture and lathe can be caused trickle loosening, and the fixture in rotation more can increase the weight of this loosening, fixture is caused to rotate irregular, namely, not on a movement locus, cause the part after processing to occur the situations such as eccentric, badly influence the precision of part.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides and a kind ofly can to overcome because fixture loosens the numerically controlled lathe fixture causing processing rear element precision difference.
For achieving the above object, the technical scheme that the utility model provides is:
A kind of numerically controlled lathe fixture, comprises clamping fixture seat, main body, collet, supporting seat, conical sleeve, location cylinder base, disk, pull bar, fixture block, connecting bolt and positioning tube; Described clamping fixture seat is fixed on main shaft, and body front end is fixedly connected with clamping fixture seat, and supporting seat is positioned at main body, and the front end of supporting seat is fixed on clamping fixture seat; Described location cylinder base is fixed on the rear end face of supporting seat, positioning tube is fixed on the rear end face of location cylinder base, body rear inwall is provided with annular groove, annular groove is built with tapered sleeve, tapered sleeve inwall is the conical surface, and described collet is set in main body, and collet rear end outer wall is provided with the conical surface, this conical surface mates with the conical surface of tapered sleeve inwall and contacts, and the rear end inwall of collet is fixed with fixture block; The front end of described collet is connected with disk, the center of disk is provided with connecting hole, and connecting hole is built-in with spherical bushing, and pull bar is positioned at the front end of disk, the rear end of pull bar is provided with screwed hole, and connecting bolt screws in the screwed hole of pull bar through the spherical bushing of disc centre.
The inner surface of described fixture block is provided with elastic layer.
The inner conical surface of described tapered sleeve is taper seat, and the conical surface of collet rear end outer wall is also taper seat.
The inner conical surface of described tapered sleeve is the rectangle conical surface, and the conical surface of collet rear end outer wall is also taper seat.
the usefulness of technique scheme is:
Basis is novel provides a kind of numerically controlled lathe fixture, adding man-hour, workpiece in rotation can drive collet and disk to take spherical bushing as axis rotation, avoid whole fixture in conventional art to rotate, make the bad stability that fixture is fixing, cause the part after processing to occur the generation of the phenomenons such as bias.
Be further described originally novel below in conjunction with the drawings and specific embodiments.
Accompanying drawing explanation
Fig. 1 is this new embodiment 1 structural representation;
Fig. 2 is the sectional view at connecting bolt place in Fig. 1.
Detailed description of the invention
embodiment 1
A kind of numerically controlled lathe fixture as shown in Figure 1-2, comprises clamping fixture seat 1, main body 2, collet 3, supporting seat 4, conical sleeve 5, location cylinder base 6, disk 7, pull bar 12, fixture block 8, connecting bolt 9 and positioning tube 10; Described clamping fixture seat 1 is fixed on main shaft 11, and main body 2 front end is fixedly connected with clamping fixture seat 1, and supporting seat 4 is positioned at main body 2, and the front end of supporting seat 4 is fixed on clamping fixture seat 1; Described location cylinder base 6 is fixed on the rear end face of supporting seat 4, positioning tube 10 is fixed on the rear end face of location cylinder base 6, main body 2 rear end inwall is provided with annular groove 20, annular groove 20 is built with conical sleeve 5, conical sleeve 5 inwall is the conical surface, and described collet 3 is set in main body 2, and collet 3 rear end outer wall is provided with the conical surface 30, this conical surface 30 mates with the conical surface of conical sleeve 5 inwall and contacts, and the rear end inwall of collet 3 is fixed with fixture block 8.
The front end of described collet 3 is connected with disk 7, the center of disk 7 is provided with connecting hole, as shown in Figure 2, connecting hole is built-in with spherical bushing 70, pull bar 12 is positioned at the front end of disk 7, and the rear end of pull bar 12 is provided with screwed hole, and connecting bolt 9 screws in the screwed hole of pull bar 12 through the spherical bushing 70 at disk 7 center, the other end of pull bar 12 is connected with the clamping cylinder of lathe, is the power source of this fixture; Be fixed on by disk on pull bar, realizing disk can rotate around spherical bushing circumference, and namely collet realizes rotating; Adding man-hour, the workpiece in rotation can drive collet and disk to be axis rotation with spherical bushing, avoids whole fixture in conventional art and rotates, make the bad stability that fixture is fixing, causes the part after processing to occur the generation of the phenomenons such as bias.
In this is novel, the inner surface of described fixture block 8 is provided with elastic layer, and this elastic layer comprises rubber ring or turn; By the setting of elastic layer, can guarantee that surface of the work can not be crushed by fixture.
