Abstract
The invention relates to a fixture for a lathe. The fixture comprises a supporting seat and a clamping sleeve, wherein a center hole for accommodating the clamping sleeve is formed in the supporting seat; the center hole comprises a taper hole and a circular hole; the clamping sleeve is arranged in the taper hole; the clamping sleeve adopts a taper structure adapted to the taper hole; a movable pull rod is arranged in the circular hole; the pull rod is fixedly connected with the clamping sleeve; a clamping hole and a plurality of notches connected with the clamping hole are formed in the clamping sleeve. The fixture disclosed by the invention is simple in structure, high in machining efficiency and low in use cost.
Description
Technical field
The present invention 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, the object of this invention is to provide a kind of structure simple, working (machining) efficiency is high, the fixture for lathe that use cost is low.
Realize technical scheme of the present invention 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.
Described pull bar and retaining sleeve are structure as a whole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of retaining sleeve;
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
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.
Described pull bar 6 is structure as a whole with retaining sleeve 4.
