Abstract
The utility model discloses a labor-saving chuck which comprises a chuck body and clamping jaws. A wire scroll is arranged in the chuck body, the bottom portions of the clamping jaws are meshed with the wire coil on the surface of the wire scroll, a swing block stretching out of the chuck body is fixed on the wire scroll, and a swing hole corresponding to the swing block is formed in the chuck body. An impact block is arranged on one side of the swing block, one end of the impact block is rotatably connected with the swing block, and a connecting piece connected with a power device is arranged at the other end of the impact block. The labor-saving chuck can reduce labor intensity of workers, and is simple in structure.
Description
Technical field
The utility model relates to a kind of chuck, relates in particular to a kind of laborsaving chuck that can external power source.
Background technology
Chuck is to be used for the mechanical device of clamping work pieces on the lathe, utilizes moving radially of the movable jaw that is distributed on the chuck body, workpiece is clamped and the machine tool accessories of location.From working power, can be divided into: hand chuck, air spider, oild chuck, electric chuck and mechanical chuck.Hand chuck is simple in structure, easy to use, but for larger-size chuck, needs bigger strength just can pull, and harder than clamping when particularly unclamping claw, not only working strength of workers is big, and efficient is also low.Though present startup chuck etc. are laborsaving, complex structure, cost are also higher.
Summary of the invention
At above-mentioned weak point of the prior art, the utility model provides a kind of chuck, and is simple in structure, can reduce working strength of workers, can make especially to unclamp chuck and become easier.
The technical solution of the utility model is a kind of laborsaving chuck, comprise chuck body and claw, be provided with the silk dish in the described chuck body, the wire ring engagement of described claw bottom and described silk panel surface, be fixed with the swinging block that stretches out chuck body on the described silk dish, described chuck body has the swing hole corresponding to described swinging block; One side of described swinging block is provided with impact block, and an end and the swinging block of described impact block are rotatably connected, and the other end of described impact block is provided with the connector that connects power set.
Further, described swinging block is the spring bloom.Spring steel has better elastic, higher yield strength, when bearing heavy load, do not cause plastic deformation, have high fatigue strength, under load acts on repeatedly, have long service life, and enough toughness and plasticity are arranged, can prevent brittle failure suddenly under percussion.
Further, the length in described swing hole equates with the range of claw.
Further, described power set are oscillating cylinder; Described power set are oscillating cylinder; Described connector is a hinge.Hinge passes to impact block with the swing of oscillating cylinder.
Further, described swinging block is provided with column, and described impact block is provided with the hole with described column loose fit.Realization is rotatably connected.
The beneficial effects of the utility model are: swinging block can be under impact block and external power set effect, and clamping work pieces need not manpower and pulls, and is time saving and energy saving; When unclamping, impact block can be given impulsive force of swinging block, makes that unclamping becomes is more prone to.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of silk dish in the utility model.
The specific embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of laborsaving chuck such as Fig. 1 and shown in Figure 2, a kind of laborsaving chuck, comprise chuck body 1 and claw 2, be provided with silk dish 8 in the described chuck body 1, wire ring 6 engagements on described claw 2 bottoms and described silk dish 8 surfaces, be fixed with the swinging block 3 that stretches out chuck body 1 on the described silk dish 8, described chuck body 1 has the swing hole corresponding to described swinging block 3; One side of described swinging block 3 is provided with impact block 4, and an end and the swinging block 3 of described impact block 4 are rotatably connected, and the other end of described impact block 4 is provided with the connector 5 that connects power set.Described swinging block 3 is the spring bloom.The length in described swing hole equates with the range of claw 2.Described power set are oscillating cylinder; Described connector 5 is a hinge.3 are provided with column 7 on the described swinging block, and described impact block 4 is provided with the hole with described column 7 loose fits.
The course of work of the present utility model is as follows, clamping work pieces: under the effect of oscillating cylinder, impact block 4 pulling swinging blocks 3 are towards a side oscillation of impact block, up to clamping work pieces.Unclamp workpiece: under the effect of oscillating cylinder, impact block 4 strikes on the swinging block 3 towards swinging block 3 motions, and impact block 4 drives the opposite side swing of swinging block 3 towards impact block 4 again, up to being totally released workpiece.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
