Abstract

The utility model provides a clamp for clamping rotary column-shaped work piece, wherein the upper part of a pair of handles, which are crosswise or in parallel hinged with each other, is provided with a chute, the connection part between the pair of handles and the inner part of the chute are fixedly provided with bolts respectively, each bolt is connected with a rotary abrasion proof soft material cylinder. The utility model can clamp the rotary column-shaped work piece other than affecting the rotation of the column-shaped work piece; when the pair of handles are crosswise hinged with each other, the utility model can clamp the slender column-shaped work piece and lower or eliminate the oscillating phenomenon of the tail end of the column-shaped work piece; at the same time, the utility model can also cut off the working piece from a chuck, thereby saving time and labor and improving the processing quality of the work piece; when the pair of handles are hinged with each other in parallel, the utility model can clamp the column-shaped work piece with relative big bore and heavy weight, which avoids the damage of the work piece caused by the work piece being not directly held due to lack of specific tools when the work piece being nearly cut off.

Description

The column anchor clamps that are used for the clamping rotary state

Technical field:

The utility model relates to a kind of field of machining anchor clamps, especially relates to a kind of can clamping being in the column of rotary state and not influencing the anchor clamps that column is rotated.

Background technology:

At present, during the cylindrical workpiece of inconvenient brachymemma, serious swing can appear to the turning processing slim in the tail end of material, can make lathe serious vibrations occur again, and the workpiece machining accuracy reduces, and material tail end casualty accident perhaps occurs.Simultaneously, with the solid cylinder workpiece when chuck scales off because the diameter of work of incision diminishes gradually, rigidity reduces, so radial cutting component can make that the part distal process is right to become curved, causes the cutting knife breakage.At this type of situation, present way is the diameter at incision workpiece when also very big, and lathe spindle is stopped operating, and with hand part is broken off with the fingers and thumb, and then restarts main shaft, and car falls the part that incision stays again, wastes time and energy.And be about to by car owing to can't directly it be caught with hand or thin bar instrument, easily cause workpiece to damage when disconnected for the bigger and heavier cylindrical workpiece of endoporus.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of can clamping being in the column of rotary state and not influencing the anchor clamps that column is rotated, and uses these anchor clamps can reduce or eliminate the swing of elongated material tail end; Simultaneously, utilize these anchor clamps directly workpiece to be cut off from chuck; In addition, these anchor clamps also can be clamped the bigger and heavier column of endoporus that is cut, and have overcome the defective that background technology exists.

The technical solution of the utility model is: be provided with chute in pair of cross or parallel hinged handle top, be fixed with bolt in the junction of handle and the chute respectively, connect a rotating wear-resisting soft material cylinder on each bolt respectively.

Excessive in order to prevent the handle slewing area, the superincumbent handle back side is provided with limiting plate.

The utility model is owing to be to be provided with chute in pair of cross or parallel hinged handle top, be fixed with bolt in the junction of handle and the chute respectively, connect a rotating wear-resisting soft material cylinder on each bolt respectively, therefore, can clamping be in the column of rotary state and not influence the column rotation, when a pair of handle cross-articulation together the time, but the elongated cylindrical workpiece cylindrical of clamping reduces or eliminates the phenomenon of its tail end swing; Also can directly workpiece be cut off from chuck simultaneously, time saving and energy saving, improve the workpiece crudy; When a pair of handle parallel when hinged, but the bigger and heavier cylindrical workpiece of clamping endoporus when avoiding it to be about to be cut off, can't directly not caught it workpiece that causes owing to there being specific purpose tool and damage.

Description of drawings:

Fig. 1 is the structural representation of the utility model handle cross-articulation form;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the structural representation of the parallel articulated form of the utility model handle;

Fig. 4 is the right view of Fig. 3.

The specific embodiment:

With reference to Fig. 1, Fig. 2, handle 1 top hinged in pair of cross is provided with chute 2, is fixed with bolt 6 in the junction of handle and the chute respectively, connect a rotating wear-resisting soft material cylinder 3 on each bolt respectively, the 4th, pad, the 5th, hold-down nut, the 7th, limiting plate.Bowlder outside needing the elongated cylindrical workpiece that is rotating of clamping, open handle earlier, then workpiece is clamped and the handle that closes gets final product, because wear-resisting soft material cylinder 3 rotates, so when it contacts with the excircle of workpiece surface, can be along with the workpiece that is rotating rotates together, reduce or eliminate the phenomenon of its tail end swing, simultaneously, when this anchor clamps holding workpiece, can directly workpiece be cut off from chuck, and need not lathe spindle is stopped, restart main shaft again after with hand part being broken off with the fingers and thumb down, cut off the part that incision stays, time saving and energy saving, improve the workpiece crudy.

With reference to Fig. 3, Fig. 4, handle 8 tops hinged in pair of parallel are provided with chute 2, are fixed with bolt 6 in the junction of handle and the chute respectively, connect a rotating wear-resisting soft material cylinder 3 on each bolt respectively, the 4th, pad, the 5th, hold-down nut, the 7th, limiting plate.When needing the bigger and heavier cylindrical workpiece of clamping endoporus, open handle earlier, put in the endoporus of hollow cylinder workpiece, handle then closes, workpiece support clamp, when avoiding it to be about to be cut off, can't directly it not caught the workpiece that causes owing to there being specific purpose tool and damage.

During use, earlier by regulating position and/or the size of the regulating wear-resisting soft material cylinder diameter requirement that reach excircle of workpiece or endoporus size of bolt in chute.

Consider the intensity size after slotting in handle top, the chute on each handle can be made as two.
