Abstract
The utility model relates to a kind of fixture for lathe, comprise supporting base and retaining sleeve, described supporting base is provided with the centre bore of accommodating retaining sleeve, centre bore is made up of bellmouth and circular port, and retaining sleeve is arranged in bellmouth, and retaining sleeve is set to the pyramidal structure adapted with bellmouth, moveable pull bar is provided with in circular port, pull bar is fixedly connected with retaining sleeve, and described retaining sleeve is provided with clamping hole, and multiple notch be connected with clamping hole.It is simple that the utility model has structure, the features such as working (machining) efficiency is high, and use cost is low.
Description
Technical field
The utility model relates to clamp art, particularly a kind of fixture for lathe.
Background technology
At present, on lathe during processing work, general use chuck or various power clamp head clamping workpiece, the complex structure of chuck or power chuck, cost is large, use also comparatively loaded down with trivial details, and the efficiency adding man-hour is also lower, the effect after impact processing.
Summary of the invention
For the problems referred to above, it is simple that the purpose of this utility model is to provide a kind of structure, and working (machining) efficiency is high, the fixture for lathe that use cost is low.
Realize the technical solution of the utility model as follows:
A kind of fixture for lathe, comprise supporting base and retaining sleeve, described supporting base is provided with the centre bore of accommodating retaining sleeve, and centre bore is made up of bellmouth and circular port, and the diameter of bellmouth upper end is greater than lower end diameter, retaining sleeve is arranged in bellmouth, retaining sleeve is set to the pyramidal structure adapted with bellmouth, and be provided with moveable pull bar in circular port, pull bar is fixedly connected with retaining sleeve, described retaining sleeve is provided with clamping hole, and multiple notch be connected with clamping hole.
Have employed above-mentioned scheme, for holding workpiece in clamping hole, pull retaining sleeve by pull bar, make it move down, due to the effect of bellmouth trough mouth, retaining sleeve tightens up to center, thus realizes the object of Workpiece clamping; Oppositely promoted by pull bar to take off workpiece, easy to use, working (machining) efficiency is high, and use cost reduces greatly.
Described pull bar and circular port are for being threaded, and be provided with internal thread in circular port, pull bar is provided with external screw thread, and advantage is that structure is simple, easy to use, and location is given firmly, not easily slides.
The described pull bar other end is connected with spacing handle, and spacing handle is circular, and its diameter is greater than circular port diameter, and advantage prevents hole, retaining sleeve off center.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the top view of retaining sleeve;
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As Fig. 1 and Fig. 2, a kind of fixture for lathe, comprise supporting base 1 and retaining sleeve 4, described supporting base 1 is provided with the centre bore of accommodating retaining sleeve 4, centre bore is made up of bellmouth 2 and circular port 3, the diameter of bellmouth 2 upper end is greater than lower end diameter, retaining sleeve 4 is arranged in bellmouth 2, retaining sleeve 4 is set to the pyramidal structure adapted with bellmouth 2, moveable pull bar 6 is provided with in circular port 3, pull bar 6 is fixedly connected with retaining sleeve 4, described retaining sleeve 4 is provided with clamping hole 5, and multiple notch 8 be connected with clamping hole 5, notch 8 is provided with three, form 120 ° of angles each other.
Described pull bar 6 and circular port 3, for being threaded, are provided with internal thread in circular port 3, and pull bar 6 is provided with external screw thread, and advantage is that structure is simple, easy to use, and location is given firmly, not easily slides.
Described pull bar 6 other end is connected with spacing handle 7, and spacing handle 7 is circular, and its diameter is greater than circular port diameter, and advantage prevents hole, retaining sleeve off center.
