Abstract
The utility model discloses a clamping device, and specifically relates to a wedge-type centring clamping device. The wedge-type centring clamping device comprises a clamp body. A hollow boss is arranged on the clamp body. A clamping device body is arranged in a cavity of the boss. The clamping device body comprises a guiding rod which can move in an up and down mode. An upper expanding block with an outer inclined plane and a lower expanding block with an outer inclined plane are actively sleeved on the guiding rod, and a reset spring is arranged between the upper expanding block and the lower expanding block. A locknut is arranged at an end of the guiding rod. A through hole is crosswise formed in a hole wall, corresponding to the outer inclined plane, of the boss. A ball nested in an O-shaped ring is arranged in the through hole. The ball is abutted against the outer inclined plane. The wedge-type centring clamping device is ingenious in structure and design, a workpiece is actively sleeved outside of the boss, the locknut is twisted, so that the upper expanding block and the lower expanding block are close inward through extrusion of the locknut, under the cooperation of the outer inclined plane and the ball, the ball is extruded outside of the through hole, and the clamping of the workpiece can be achieved. Compared with the prior art, the wedge-type centring clamping device is good in clamping effect, convenient to operate and is suitable for clamping components with deep through holes.
Description
Technical field
The utility model relates to a kind of grip device, is specifically related to a kind of wedge-type centering and clamping apparatus.
Background technology
In the process of parts; In order to guarantee machining accuracy and effect, it need be fixed in first being processed, anchor clamps arise at the historic moment.The parts of band deep via are owing to the particularity of its structure, and existing anchor clamps are unsatisfactory to the effect of its clamping; Be difficult to its clamping, and complex structure, cause inconvenient operation, thereby influence working (machining) efficiency.
The utility model content
The purpose of this utility model is to provide a kind of good clamping effect, easy to operate wedge-type centering and clamping apparatus.
The utility model is achieved through the following technical solutions:
A kind of wedge-type centering and clamping apparatus, comprise chuck body, chuck body is provided with cannular boss, be provided with clamping device in the cavity of described boss, described clamping device comprises the guide rod of a upper and lower movement, kink has the upper and lower bloated piece on the outer inclined-plane of band on the guide rod, is provided with back-moving spring between the upper and lower bloated piece, and the end of described guide rod is provided with locking nut; Laterally be provided with through hole on the boss hole wall of described outer inclined-plane correspondence, be provided with the nested ball of O shape circle in the through hole, described ball offsets with outer inclined-plane.
The beneficial effects of the utility model are:
The utility model structural design is ingenious, and the workpiece kink outside boss, is turned locking nut, and this moment, upper and lower bloated piece was subjected to the extruding of nut inwardly close, and under the cooperation of inclined-plane and ball, ball is extruded outside the hole, can realize the clamping to workpiece outside.Compared with prior art, the utility model good clamping effect, easy to operate is applicable to the clamping of the parts of band deep via.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
By reference to the accompanying drawings shown in 1, a kind of wedge-type centering and clamping apparatus, comprise chuck body 1, chuck body 1 is provided with cannular boss 2, be provided with clamping device in the cavity of described boss 2, described clamping device comprises the guide rod 3 of a upper and lower movement, and kink has the bloated piece 4 of going up of the outer inclined-plane 8 of band and following bloated piece 5 on the guide rod 3, be provided with back-moving spring 6 between the upper and lower bloated piece, the end of described guide rod 3 is provided with locking nut 7; Laterally be provided with through hole 9 on boss 2 hole walls of described outer inclined-plane 8 correspondences, be provided with O shape in the through hole 9 and enclose 10 nested balls 11, described ball 11 offsets with outer inclined-plane 8.
At first with workpiece 12 kinks outside boss 2, turn locking nut 7, this moment, upper and lower bloated piece was subjected to the extruding of nut 7 inwardly close, under the cooperation of inclined-plane 8 and ball 11, ball 11 is extruded outside the hole, can realize the clamping to workpiece 12 outside.Consider when turning nut 7, for preventing guide rod 3 rotations, can be with on the bloated piece 5 under the tail end embedding of guide rod 3, also can be as present embodiment, chuck body 1 bottom arranges groove seat 13, and the tail end of guide rod 3 is inserted in the groove seat 13, and horizontally set latch 14, prevent guide rod 3 rotations.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
