Abstract
The invention relates to a clamping fixture, in particular to a bidirectional clamping fixture. The bidirectional clamping fixture comprises a fixture body, an outer wall clamping jaw, an inner wall clamping jaw, a bolt, a nut and a washer, wherein the outer wall clamping jaw and the inner wall clamping jaw are used for clamping a workpiece; the bolt serves as a force application device; the driving end of the outer wall clamping jaw and the middle part of the inner wall clamping jaw are respectively hinged on the fixture body; driven ends of the outer wall clamping jaw and the inner wall clamping jaw are respectively used for clamping the workpiece; the middle part of the outer wall clamping jaw is provided with a threaded hole; the bolt passes through the threaded hole; one end of the bolt is connected with the nut and the washer; and the other end of the bolt is hinged with the driving end of the inner wall clamping jaw. The bidirectional clamping fixture disclosed by the technical scheme adopted by the invention is strong in adjustability on pressure strength of the workpiece, accurate in positioning, simple in structure and easy in operation.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of Bidirectional clamping anchor clamps.
Background technology
In the machining manufacturing industry, the locating clip clamper plays very 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 has different requirements to clamping device, one-sided clamping device, side direction horizontal is easy to make the workpiece perk to break away from anchor point and destroys the location when clamping, cause the unstable 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 of free gap unsatisfactory to inside, therefore, urgent need is a kind of can be the workpiece of free gap to position the device of clamping to inside.Common clamping device has the following disadvantages when being the workpiece of free gap 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, complexity and operability are poor to the clamping device mechanism structure for traditional double.
Summary of the invention
It is strong that the technical problem to be solved in the present invention provides a kind of clamping dynamics modulability, registration and simple in structure, easy to operate Bidirectional clamping anchor clamps.
In order to solve the problems of the technologies described above, the invention provides a kind of Bidirectional clamping anchor clamps, 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, one end and described nut be connected packing ring and be connected, the drive end of the other end and inwall jaw is hinged, and cover has Compress 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 simultaneously bolt drive inwall jaw moves along the axis direction of bolt, its driven end is then along rotating to clamped workpiece one pressure to the right clockwise, when workpiece by outer wall downwards and inwall pressure to the right do simultaneously the time spent, 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 direction that bolt moves 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 Bidirectional clamping anchor clamps of technique scheme to have the following advantages: 1, owing to having 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 the mode that has adopted Bidirectional clamping, therefore high to the setting accuracy of workpiece; 3, because the structure that this Bidirectional clamping anchor clamps adopt 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 embodiment of the invention Bidirectional clamping anchor clamps.
The specific embodiment
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As shown in Figure 1, the invention provides a kind of Bidirectional clamping anchor clamps, 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 with the nut 4 that is provided with handle 5 and is connected, the drive end of the other end and inwall jaw 2 is hinged, and cover has Compress Spring 7 on the bolt 6, and handle 5 is set on the nut 4.
Specifically using method is: 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 is then along rotating to clamped workpiece one pressure to the right clockwise, when workpiece by outer wall downwards and inwall pressure to the right do simultaneously the time spent, 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 the direction that bolt 6 moves 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 invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
