Abstract
The utility model relates to a clamping fixture, specifically to a bidirectional clamping fixture comprising a fixture body, an outer wall clamping jaw, an inner wall clamping jaw, a bolt serving as a force-applying device, a nut and a gasket. The outer wall clamping jaw and the inner wall clamping jaw are used for clamping a workpiece; a drive end of the outer wall clamping jaw and a middle part of the inner wall clamping jaw are hinged to the fixture body; driven ends of the outer wall clamping jaw and the inner wall clamping jaw clamp the workpiece; a middle part of the outer wall clamping jaw is provided with a threaded hole; the bolt passes through the threaded hole; and one end of the bolt is connected with the nut and the gasket and the other end of the bolt is hinged to a drive end of the inner wall clamping jaw. The bidirectional clamping fixture has the advantages of high adjustability of pressing force applied to the workpiece, accurate positioning, simple structure and easy operation.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of two-way clamping device.
Background technology
In the machining manufacturing industry, the locating clip clamper plays important effect, and it guarantees that the relative lathe of workpiece, cutter etc. are in correct position all the time, guarantees uniformity and the crudy of workpiece processing.
Dissimilar workpiece have different requirements to clamping device, one-sided clamping device, the side direction level is easy to make the workpiece perk to break away from anchor point and destroys the location when clamping, cause the instability of workpiece machining accuracy, in addition, thereby common clamping device all is that the surface of the work application of force is fixed its position in process, but is its locating effect of workpiece in free crack unsatisfactory to inside, therefore, urgent need is a kind of can be the workpiece in free crack to position the device of clamping to inside.Common clamping device has the following disadvantages when being the workpiece in free crack to position clamping to inside: the modulability of the dynamics of exerting pressure when 1, are exerted pressure in the location on the surface is not strong, easily causes the damage of workpiece; 2, one-sided exerting pressure clamps the very difficult accurate location of workpiece in process of realizing; 3, traditional double is poor than complexity and operability to the clamping device mechanism structure.
The utility model content
It is strong that the technical problems to be solved in the utility model provides a kind of clamping dynamics modulability, locatees accurate and simple in structure, easy to operate two-way clamping device.
In order to solve the problems of the technologies described above, the utility model provides a kind of two-way clamping device, include chuck body, the outer wall jaw that is used for clamping work pieces and inwall jaw, the bolt as force application apparatus, nut, packing ring, wherein, the middle part of the drive end of described outer wall jaw and inwall jaw all is articulated in chuck body, the equal clamping work pieces of driven end, screwed hole is established at outer wall jaw middle part, described bolt passes screwed hole, the one end is connected with described packing ring with described nut, the drive end of the other end and inwall jaw is hinged, is with the compression spring on the described bolt.
During nut screwing clamping, the driven end of outer wall jaw moves clockwise to the downward pressure of clamped workpiece one, the drive end of the inwall of bolt drive simultaneously jaw moves along the axis direction of bolt, its driven end then rotates to clamped workpiece one pressure to the right along clockwise direction, when workpiece by outer wall downwards and inwall pressure to the right do the time spent simultaneously, its position is accurately fixed, and workpiece is clamped; When nut loosens, the driven end of outer wall jaw counterclockwise rotates, the drive end of inwall jaw moves along the bolt travel direction simultaneously, its driven end is then along counterclockwise rotating, depart from workpiece, at this moment, thus the outer wall pressure of workpiece and inner wall pressure disappear simultaneously and unclamp the workpiece that is fixed.
Adopt the two-way clamping device of technique scheme following advantage is arranged: 1, owing to adopted the combination of bolt, nut, spring, therefore the pressurization dynamics of workpiece is easily regulated, can be to the damage that causes of workpiece; 2, owing to adopted the mode of two-way clamping, therefore to the setting accuracy height of workpiece; 3, because the structure that this two-way clamping device adopts bolt and nut to fix to clamp realizes pressurization, manually can regulate the pressurization dynamics, so structure is simpler and easy to operate.
As preferred version, consider the manually operated convenience of nut, therefore on the described nut handle is set.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the two-way clamping device of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As shown in Figure 1, the utility model provides a kind of two-way clamping device, include chuck body 1, the outer wall jaw 3 and the inwall jaw 2 that are used for clamping work pieces, bolt 6 as force application apparatus, nut 4, packing ring 8, wherein, the middle part of the drive end of outer wall jaw 3 and inwall jaw 2 all is articulated in chuck body 1, the equal clamping work pieces of driven end, screwed hole is established at outer wall jaw 3 middle parts, bolt 6 passes screwed hole, the one end is connected with packing ring 8 with the nut 4 that is provided with handle 5, the drive end of the other end and inwall jaw 2 is hinged, is with compression spring 7 on the bolt 6, and handle 5 is set on the nut 4.
Specifically be to use method to be: when nut 4 is tightened, the driven end of outer wall jaw 3 moves clockwise to the downward pressure of clamped workpiece one, the drive end of bolt 6 drive inwall jaws 2 moves along the axis direction of bolt 6 simultaneously, its driven end then rotates to clamped workpiece one pressure to the right along clockwise direction, when workpiece by outer wall downwards and inwall pressure to the right do the time spent simultaneously, its position is accurately fixed, and workpiece is clamped; When nut 4 loosens, the driven end of outer wall jaw 3 counterclockwise rotates, the drive end of inwall jaw 2 moves along bolt 6 travel directions simultaneously, its driven end is then along counterclockwise rotating, depart from workpiece, at this moment, thus the outer wall pressure of workpiece and inner wall pressure disappear simultaneously and unclamp the workpiece that is fixed.
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.
