Abstract
The invention discloses a clamp for cylindrical workpieces. The clamp comprises a clamp body and a first clamping jaw and a second clamping jaw which are used for clamping cylindrical workpieces. The clamp is characterized in that a lead screw is horizontally arranged on the clamp body, wherein threads which are reverse in direction are respectively arranged at the two ends of the lead screw; the center of the lead screw is fixed by a bolt, and the two ends of the lead screw are respectively connected with the first clamping jaw and the second clamping jaw through a first nut and a second nut; the first clamping jaw and the second clamping jaw are hinged with the clamp body through a first connecting shaft and a second connecting shaft; the bottom layer of a cavity formed between the first clamping jaw and the second clamping jaw is provided with an elastic layer with certain elasticity; the first clamping jaw and the second clamping jaw are in the shapes of arcs; and auxiliary clamping jaws capable of clamping the cylindrical workpieces are symmetrically arranged on the first clamping jaw and the second clamping jaw. When used for clamping the cylindrical workpieces, the clamp is firmer, so that a skidding phenomenon is avoided, and processing effects are improved.
Description
Technical field
The present invention relates to a kind of fixture of cylindrical work.
Background technology
Milling machine is the lathe with milling cutter, workpiece being carried out to Milling Process.Can process the profile of more complicated, efficiency comparatively planer is high, is used widely in machine-building and repairing department.Milling machine, in process, needs to carry out clamping and positioning to workpiece, and when traditional fixture is used for the clamping and positioning of cylindrical work, the sidewall point of two jaws and cylindrical work or linear contact lay, be easy to occur skidding, affect processing effect.
Summary of the invention
For the problems referred to above, the invention provides a kind of fixture of cylindrical work, during for clamp cylinders shape workpiece, more firmly, avoid occurring skidding, improve processing effect.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of fixture of cylindrical work, comprise chuck body and for the first jaw of clamp cylinders shape workpiece and the second jaw, it is characterized in that, described chuck body has been horizontally disposed with leading screw, the two ends of described leading screw are respectively arranged with the contrary screw thread in direction, the center of described leading screw fixed by screw and two ends respectively by the first nut, second nut is connected with the second jaw with the first jaw, it is hinged that described first jaw and the second jaw pass through the first connecting axle and the second connecting axle and chuck body, the bottom of the cavity formed between described first jaw and the second jaw is provided with has certain flexible elastic layer, described first jaw and the second jaw curved, and the first jaw and the second jaw are symmetrically arranged with can the auxiliary jaw of clamp cylinders shape workpiece.
Preferably, when the first jaw and the second jaw are in clamped position, described auxiliary jaw is the arc of horizontal-clamping cylindrical work.Further, described auxiliary jaw is connected in intersecting cross with the first jaw and the second jaw respectively.
The invention has the beneficial effects as follows: when screw turns, hand of spiral due to its two ends is contrary and self fixed by screw, can only rotate and can not move, drive the first nut and the second nut to move, the movement of nut drives two jaws to rotate around pin joint then, coordinate the elastic layer of bottom and the auxiliary jaw at top simultaneously, common clamp cylinders shape workpiece, during for clamp cylinders shape workpiece, more firmly, avoid occurring skidding, improve processing effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fixture of a kind of cylindrical work of the present invention;
The mark implication of accompanying drawing is as follows:
1: chuck body; 2: leading screw; 3: screw; 4: the first nuts; 5: the second nuts; 6: the first connecting axles; 7: the second connecting axles; 8: the first jaws; 9: the second jaws; 10: cylindrical work; 11: elastic layer; 12: auxiliary jaw.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.
A kind of fixture of cylindrical work, comprise chuck body 1 and the first jaw 8 and the second jaw 9 for clamp cylinders shape workpiece 10, as shown in Figure 1, described chuck body 1 has been horizontally disposed with leading screw 2, the two ends of described leading screw 2 are respectively arranged with the contrary screw thread in direction, and such as, the right-hand member of the leading screw 2 in Fig. 1 arranges left hand thread, then left end arranges right-handed thread, and the screw thread at the two ends of best leading screw 2 is identical, equally spaced.
The center of described leading screw 2 is fixed by screw 3 and two ends are connected with the second jaw 9 with the first jaw 8 respectively by the first nut 4, second nut 5, it is hinged that described first jaw 8 and the second jaw 9 pass through the first connecting axle 6 and the second connecting axle 7 and chuck body 1, the bottom of the cavity formed between described first jaw 8 and the second jaw 9 is provided with has certain flexible elastic layer 11, described first jaw 8 and the second jaw 9 curved, and the first jaw 8 and the second jaw 9 are symmetrically arranged with can the auxiliary jaw 12 of clamp cylinders shape workpiece 10.
Can according to the optimum position of the size Design assistant jaw 12 of cylindrical work to be clamped: namely, when the first jaw 8 and the second jaw 9 are in clamped position, the arc of described auxiliary jaw 12 in horizontal-clamping cylindrical work 10.Illustrate only part in Fig. 1, from the side, in fact, auxiliary jaw 12 is connected in the cross intersected with the first jaw 8 and the second jaw 9 respectively, symmetrical clamp cylinders shape workpiece.
Wherein, described elastic layer 11 has certain thickness abrasive rubber layer, or described elastic layer 11 is the springs with certain altitude.Wherein, in the first scheme, preferably the center of abrasive rubber layer is provided with the cambered surface to lower recess, clamping effect is better.
When leading screw 2 rotates, hand of spiral due to its two ends is contrary and self fixed by screw 3, can only rotate and can not move, drive the first nut 4 and the second nut 5 to move, the movement of nut drives two jaws to rotate around pin joint then, coordinate the elastic layer 11 of bottom and the auxiliary jaw 12 at top simultaneously, common clamp cylinders shape workpiece 10, during for clamp cylinders shape workpiece 10, more firmly, avoid occurring skidding, improve processing effect.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present invention.
