Abstract

The utility model relates to a fixture for a lathe. The fixture comprises a hollow taper sleeve 1, a spring 10, a push rod 6 and a hollow spring collet 3. An elastic collet portion 3-2 is arranged at the front end of the hollow spring collet 3, an internal thread section 3-1 is arranged at the rear end of the hollow spring collet 3, the push rod 6 is connected into the hollow spring collet 3 in a threaded manner, the hollow spring collet 3 is arranged inside the hollow taper sleeve 1 in a matched manner through a taper surface, one end of the spring 10 is abutted to the end face of the push rod 6, and the other end of the spring 10 is abutted to the bottom of the hollow taper sleeve 1. By the aid of the fixture, workpiece positioning precision can be improved, auxiliary time of mounting a workpiece is saved, and the labor intensity of workers is reduced.

Description

A kind of clamp for lathe
Technical field
The utility model relates to a kind of anchor clamps, especially a kind of clamp for lathe.
Background technology
The engine lathe clamping workpiece often adopts scroll chuck or chuck at present, part of every processing all need use the voltaic spanner that chuck is clamped and unclamp, not only clamping workpiece efficient is low, and labor strength is also large, and the uniformity of Workpiece Machining Accuracy also is difficult to guarantee when batch machining.Chinese patent literature (ZL201020689340.7) discloses a kind of taper sleeve expander fixture of numerical-control lathe, realize by the butterfly spring as main clamping force, when promoting extension bar and compressing butterfly spring, promote pushing sleeve by connecting pin, expander shrinks, realize unclamping of workpiece, after the false reasoning that promotes extension bar was withdrawn from, butterfly spring promoted extension bar, retracts pushing sleeve by connecting pin, expander expands, and workpiece is clamped.These anchor clamps are fit to the quick-clamping of cover parts, but then inapplicable for axial workpiece.
The utility model content
The technical problems to be solved in the utility model is: a kind of turning attachment of quick-clamping part is provided, improves shaft-like workpiece and adding the positioning accuracy in man-hour, the non-cutting time when saving the workpiece installation, reduce labor strength.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of clamp for lathe, comprise hollow tapered sleeve, spring, push rod and hollow collet, described hollow collet has the elastic clip head of front end and the internal thread segment of rear end, push rod is by the inside of thread connection at described hollow collet, described hollow collet is by the inside of cone match in described hollow tapered sleeve, described spring one end withstands on the end face of push rod, and the other end withstands on the bottom of hollow tapered sleeve.
Preferably, described push rod comprises apical axis, respectively by thread connection at apical axis, the locking nut of left end and adjusting nut, the internal thread segment that the outer surface of described adjusting nut is provided with the rear end of external screw thread and hollow collet links.
Preferably, described clamp for lathe also comprises and the joining end cap of described hollow tapered sleeve.
The beneficial effects of the utility model are, have solved the defective that exists in the background technology, can realize quick-clamping during the batch machining axial workpiece on lathe, reduce workman's labour intensity when production efficiency obtains to improve.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Among the figure: 1. hollow tapered sleeve; 2. end cap; 3. hollow collet; 3-1. internal thread segment; 3-2. elastic clip head; 4. workpiece; 5. top; 6. push rod; 6-1. apical axis; 6-2. adjusting nut; 6-3. locking nut; 7. spring.
The specific embodiment
With preferred embodiment the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of clamp for lathe as shown in Figure 1, comprise hollow tapered sleeve 1, spring 7, push rod 6 and hollow collet 3, described hollow collet 3 has the elastic clip head 3-2 of front end and the internal thread segment 3-1 of rear end, push rod 6 is by the inside of thread connection at described hollow collet 3, described hollow collet 3 is by the inside of cone match in described hollow tapered sleeve 1, described spring 10 1 ends withstand on the end face of push rod 6, and the other end withstands on the bottom of hollow tapered sleeve 1.
Preferably, described push rod 6 comprises apical axis 6-1, and by locking nut 6-3 and the adjusting nut 6-2 of thread connection at apical axis 6-1 left end, the internal thread segment 3-1 that the outer surface of described adjusting nut 6-2 is provided with the rear end of external screw thread and hollow collet 3 links respectively.Adjusting nut 6-2 in the determining positions on the apical axis 6-1 the maximum elastic force of the turning attachment of the described quick-clamping spring 7 during at clamping work pieces 4, namely the closer to apical axis 7 left ends, the elastic force of spring 10 is larger, the effect that ejects workpiece 4 is also just better.
Preferably, the utility model also comprises and described hollow tapered sleeve 1 joining end cap 2, and described end cap 2 can prevent that the turning attachment of quick-clamping from ejecting hollow collet 3 and push rod 6 together when unclamping workpiece 4.
Operation principle of the present utility model is as follows: hollow tapered sleeve 1 can be contained on the three-jaw self-centering chuck, can match with the lathe spindle taper hole when described hollow tapered sleeve 1 left outer surface is the conical surface.During clamping workpiece, first workpiece 4 is inserted hollow collet 3 right-hand members, then with top 5 right-hand members that withstand workpiece 4 it is held out against left, at this moment workpiece 4 will promote apical axis 6-1 and be moved to the left, then apical axis 6-1 also is moved to the left with hollow collet 3, the elastic clip head 3-2. of hollow like this collet 3 shrinks, and realizes the clamping of workpiece 4; After workpiece 4 machines, unclamp toply 5, then hollow collet 3 moves right under the effect of spring 7, realizes unclamping of workpiece 4.
What describe in the above specification is the specific embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field after having read specification can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of utility model.
