Abstract
The invention relates to a clamping device, in particular to a clamping device of a rotary pressing plate. The clamping device comprises a clamp body, a jaw for pressing a lower surface of a workpiece and an adjusting nut used as a force applying device, wherein the clamp body is provided with a baffle used for pressing an upper surface of the workpiece; the jaw vertically penetrates through the clamp body; the lower part of the jaw is designed to be L-shaped and used for pressing the lower surface of the workpiece; the upper part of the jaw is matched with the adjusting nut and fixedly connected with a handle; and the handle is located above the adjusting nut. With the adoption of the technical scheme of the invention, the clamping device of the rotary pressing plate has the characteristics of simple structure, low cost and convenience for use.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of rotary pressing plate clamping device.
Background technology
In industry spot, also more and more higher to the positioning accuracy request of each lathe in the process and each manufacturing procedure along with the required precision to workpiece is more and more higher, so clamping device is absolutely necessary.And the pressing plate clamping device is wherein common a kind of clamping device, and the nut that this clamping device normal open overregulates on the pressing plate is with the dynamic pressure plate workpiece pressing.
On-the-spot in small-scale workshops, this clamping device has solved process requirements to a certain extent, but because the environmental factor of operation field and treat the irregular of workpiece pressing profile, and the many in one direction motions of pressing plate, thus cause workpiece clamp with the process that fetches in a lot of difficulties appear.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of rotary pressing plate clamping device simple in structure, with low cost and easy to use.
In order to solve the problems of the technologies described above, the invention provides a kind of rotary pressing plate clamping device, comprise chuck body, be used for the claw of workpiece pressing lower surface, as the adjusting nut of force application apparatus, wherein, chuck body is provided with the baffle plate of workpiece pressing upper surface, claw vertically passes chuck body, L-type is arranged in its underpart, is used for the workpiece pressing lower surface, and claw top cooperates with adjusting nut, described claw top is fixedly connected with handle, and this handle is positioned at the adjusting nut top.
Adopt the rotary pressing plate clamping device of technique scheme to have following advantage: 1, to increase handle because this rotary pressing plate clamping device is only simple at original common pressing plate clamping device, satisfied simultaneously the process requirements of miniature workpiece, therefore simple in structure and with low cost; 2, because handle drive claw circumferentially rotates, avoided because the irregularly shaped clamping difficulty of bringing of the environmental factor of operation field and workpiece is therefore easy to use.
As preferred version, thereby consider that turning handle drives in the circumferential process of rotating of claw, claw is difficult for the location when clamping, thus be provided with shotpin in the middle part of the described claw, and chuck body is provided with the stopper slot of 90 ° of rotations of restriction shotpin.
As preferred version, consider adjusting nut in clamping process, with chuck body extruding place very large frictional force is arranged, for reducing its frictional force, and be convenient in time change wearing terrain, extruding place of described adjusting nut and chuck body is provided with packing ring.
Description of drawings
Fig. 1 is the structural representation of the rotary pressing plate clamping device of the embodiment of the invention;
Fig. 2 is the A-A partial cutaway schematic of the rotary pressing plate clamping device of the embodiment of the invention.
The specific embodiment
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As depicted in figs. 1 and 2, the invention provides a kind of rotary pressing plate clamping device, comprise chuck body 1, the claw 2 that is used for the workpiece pressing lower surface, adjusting nut 3 as force application apparatus, wherein, chuck body 1 is provided with the baffle plate of workpiece pressing upper surface, claw 2 vertically passes chuck body 1, L-type is arranged in its underpart, be used for workpiece pressing, its top is provided with the screw thread that is complementary with adjusting nut 3, and for reducing friction, extruding place in adjusting nut 3 and chuck body 1 is provided with packing ring 6, and claw 2 tops are fixedly connected with handle 5, and this handle 5 can be regulated claw 2 and circumferentially rotate, claw 2 middle parts are provided with shotpin 7 simultaneously, and chuck body 1 is provided with the stopper slot of restriction shotpin 7 nine ten degree rotations.
Concrete using method is: at first workpiece 4 is placed on the chuck body 1, turning handle 5 again, claw 2 is in clamps the position, then rotate adjusting nut 3, drive claw 2 driven ends and move upward clamping work pieces 4; If take out workpiece 4, then at first counter-rotate adjusting nut 3, then turning handle 5, claw 2 are in unclamp the position to get final product.
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.
