Abstract
The utility model relates to a novel chuck, comprising a chuck body and a connecting rod, wherein the connecting rod is arranged in the chuck body. The novel chuck is characterized in that one end of the connecting rod is provided with a connecting block, and the other end is disposed on a pull bar; an oblique guiding hole is disposed in the upper part of the chuck body; a guide column is disposed in the guiding hole; the guide column is provided with a groove; the top end of the connecting block cooperates with the groove; the top end of the guide column is provided with a clamping block; the chuck body is provided with a plurality of positioning pins. The novel chuck is advantageous in that when workpiece clamping is conducted, with the oblique design of the guide column in the chuck body, the clamping block of the guide column, when being pulled, can not only generate radial clamping force, but also axial drawing force, and thereby the positioning of workpiece can be accurate and reliable, and no "discharging" of workpieces will occur.
Description
Technical field
The utility model relates to a kind of chuck, refers in particular to a kind of novel chuck of in numerically controlled lathe, using, and belongs to the machine tool element technical field.
Background technology
When the lathe in machining workpiece, generally adopt the gripper chuck clamping of workpieces, but the problem that the gripper chuck clamping of workpieces that uses is at present the most often run into is that workpiece " is told " outward; Most of reason is that service time is long more owing to connect the gapped between the gathering sill of piece and chuck body of claw on the chuck, and it is big more to support the gap that produces owing to wearing and tearing between piece and the chuck gathering sill; During the claw clamping work pieces, because reaction force, turning up of claw or introversion have just been caused in this gap like this; During clamping work pieces, cause " telling " phenomenon outward, make the workpiece axial location inaccurate; For the higher part of required precision, this kind chuck can not meet the demands.
The utility model content
The utility model purpose is for the deficiency that overcomes prior art a kind of radially clamping force that both produced to be provided, and produces axial tension again, makes workpiece spindle to accurate positioning, reliable novel chuck.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of novel chuck, comprise chuck body and connecting rod, and said connecting rod is arranged in the chuck body, it is characterized in that: said connecting rod one end is provided with contiguous block, and the other end is arranged on the pull bar; Said chuck body top is provided with an oriented hole; Be provided with guide pillar in the said pilot hole; Said guide pillar is provided with groove; Said contiguous block top cooperates with the groove convex-concave; Said guide pillar top is provided with clamp; Also be provided with a plurality of alignment pins on the said chuck body.
Preferably, the angle of inclination of said pilot hole and horizontal line angle are 22 °.
Preferably, said alignment pin is 3～6.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of novel chuck of the utility model scheme; When the clamping workpiece, because the apsacline of guide pillar design in the chuck body, when pulling; Clamp on the guide pillar had both produced radially clamping force to workpiece; Produce axial tension again, make accurate work piece positioning, reliable, workpiece can not occur and " tell " phenomenon outward.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the full sectional view of a kind of novel chuck of the utility model;
Wherein: 1, pull bar; 2, connecting rod; 3, contiguous block; 4, chuck body; 5, guide pillar; 6, alignment pin; 7, clamp; 8, groove; 9, pilot hole; 10, workpiece.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1 is the described a kind of novel chuck of the utility model, comprises chuck body 4 and connecting rod 2, and said connecting rod 2 is arranged in the chuck body 4, and said connecting rod 2 one ends are provided with contiguous block 3, and the other end is arranged on the pull bar 1; Said chuck body 4 tops are provided with the pilot hole 9 with 22 ° of horizontal plane inclinations; Be provided with guide pillar 5 in the said pilot hole 9; Said guide pillar 5 is provided with groove 8; Said contiguous block 3 tops and 8 concavo-convex cooperations of groove; Said guide pillar 5 tops are provided with clamp 7; Also be provided with 3 alignment pins 6 on the said chuck body 4.The hydraulic jack (not shown) is connected with chuck body 4 interior tension connecting rods 2 through pull bar 1, and tension connecting rod 2 drives contiguous blocks 3 and moves axially, and contiguous block 3 drives guide pillar 5 again; The pilot hole 9 of the 22 ° of inclinations in edge and horizontal plane moves, and clamp 7 is fixed on the guide pillar 5, when guide pillar 5 moves along pilot hole 9 backward; Clamp 7 had both moved down, and also moved backward simultaneously, was clamped to the outer bowlder of workpiece 10 when clamp 7; Except that producing radially clamping force, also produce axial tightening force, the rear end face of workpiece 10 is abutted against on 3 axial location pins 6; Make it accurate positioning, reliable, workpiece can not occur and " tell " phenomenon outward.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of novel chuck of the utility model scheme; When the clamping workpiece, because the apsacline of guide pillar design in the chuck body, when pulling; Clamp on the guide pillar had both produced radially clamping force to workpiece; Produce axial tension again, make accurate work piece positioning, reliable, workpiece can not occur and " tell " phenomenon outward.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
