Description
Technical field
The utility model relates to technical field of tooling clamps, especially a kind of screw rod fixture.
Background technology
In current screw flight process, one end of screw rod is clamped on machine tool three-jaw chuck, then just direct feed is cut, but because screw rod can bear very large radial cutting force when processing, screw rod is easy to produce vibrations, thus cause the rotten tooth of screw thread, grind one's teeth, therefore qualification rate is high and cannot ensure the precision of screw thread, and this kind of phenomenon more highlights when screw rod is longer.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of screw rod fixture.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of screw rod fixture, comprises back seat, screw rod folder bucket, chuck and locking member; The front end of described back seat is provided with connecting hole, and the rear end of described screw rod folder bucket is provided with connecting axle, and described connecting axle is rotatably assemblied in described connecting hole by bearing; Be provided with the folder chamber of front opening in described screw rod folder bucket, the front end in described folder chamber is provided with tapered portion; Described chuck is taper, and it is removably assemblied in described tapered portion, and the front end of described chuck is placed in described folder chamber front end outer side;
Described locking member comprises connecting portion and top, and the connecting portion of described locking member is set on the front end outer wall of described screw rod folder bucket, and chuck is supported in the top of described locking member front end with the locking of described locking member makes it to the inside compressing of folder chamber.
Compared with prior art, screw rod is except clamping by lathe, be clamped on lathe at the other end of screw rod by the utility model, when processing, fixture gives cutting force suffered on screw rod one counterforce counteraction workpiece, screw rod is stablized, can not vibrations be produced, thus improve the qualification rate of screw thread.
Further, locking member is locking nut, and described connecting portion is the sidepiece of locking nut, and described top is the front end face of locking nut, is provided with through hole in the middle part of this front end face.
Further, conveniently when the screw rod that is fixedly clamped, screw rod folder bucket can not produce relative motion relative to locking member, is provided with clamping face symmetrically, is held on clamping face by spanner or clip in the middle part of screw rod folder bucket, static screw rod folder bucket.
Further, described screw rod folder bucket is provided with retaining convex rib, i.e. close described clamping face place in the middle part of screw rod folder bucket, and described convex tendon is supported on the front end face of back seat connecting hole, positions when facilitating screw rod to press from both sides barrel assembly postpone seat.
Further, what bearing was arranged side by side is provided with two.
Accompanying drawing explanation
State diagram when Fig. 1 is utility model works;
Fig. 2 is explosive view of the present utility model;
Fig. 3 is sectional view of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figures 2 and 3, screw rod fixture of the present utility model, comprises back seat 1, screw rod folder bucket 2, chuck 4 and locking member 3; The front end of described back seat 1 is provided with connecting hole 13, and the rear end of described screw rod folder bucket 2 is provided with connecting axle 25, and described connecting axle 25 is rotatably assemblied in described connecting hole 13 by bearing 11, and what preferred bearing 11 was arranged side by side establishes two; Be provided with the folder chamber 21 of front opening in described screw rod folder bucket 2, the front end in described folder chamber 21 is provided with tapered portion 211; Described chuck 4 is taper, and it is removably assemblied in described tapered portion 211, and the front end 41 of described chuck 4 is placed in described folder chamber 21 front end outer side; Described locking member 3 comprises connecting portion 31 and top 32, the connecting portion 31 of described locking member 3 is threaded on the front end outer wall 22 of screw rod folder bucket 2, and chuck is supported in the top 32 of described locking member 3 front end 41 with the locking of described locking member 3 makes it to the inside compressing of folder chamber 21.
Locking member 3 is locking nut, and described connecting portion 31 is the sidepiece of locking nut, and described top 32 is the front end face of locking nut, is provided with through hole 321 in the middle part of this front end face.
Conveniently when the screw rod 5 that is fixedly clamped, screw rod folder bucket 2 can not produce relative motion relative to locking member 3, clamping face 23 is provided with symmetrically in the middle part of screw rod folder bucket 2, be held on clamping face by spanner or clip, static screw rod folder bucket 2, in addition, screw rod folder bucket 2 is provided with retaining convex rib 24, i.e. close clamping face 23 place in the middle part of screw rod folder bucket 2, described back seat is supported on described convex tendon 24, positions when facilitating screw rod to press from both sides barrel assembly postpone seat.
As shown in Figure 1, add and first the clamping part 12 of back seat 1 is fixed on lathe man-hour, then screw rod one end is clamped on the scroll chuck 6 of lathe, the other end then inserts folder chamber, by repairing tight locking member, make the inwall of step surface to the inside compressing of chuck to folder chamber, thus clamping screw; Last lathe feed, carries out turning.
Compared with prior art, screw rod is except clamping by lathe, be clamped on lathe at the other end of screw rod 5 by the utility model, when processing, fixture gives cutting force suffered on screw rod one counterforce counteraction workpiece, screw rod is stablized, can not vibrations be produced, thus improve the qualification rate of screw thread.
