Abstract
The invention relates to a clamping device, in particular to a rotary inner clamping device. The device comprises a cylindrical clamp main body, wherein a ring of uniformly distributed clamping jaws are hinged at the circumference of the clamp main body; the clamping jaws radially rotate along the clamp main body; a driven end of each of the clamping jaws is used for clamping inner holes of a clamping workpiece, and a driving end of the clamping jaw is butted against the lower edge of a cam ring sleeved on the clamp main body; the upper edge of the cam ring is horizontally and slidingly matched with a convex ring arranged on the clamp main body; cams butted against the driving end of the clamping jaw are arranged at the lower edge of the cam ring; and a hole for inserting a handle is formed at the outer edge of the cam ring. By adopting the technical scheme, the rotary inner clamping device is simple in structure, convenient to operate and low in cost.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of interior clamping device.
Background technology
Generally when machining, workpiece to be processed all will be fixed, and clamping device plays vital effect when machining.
Although present clamping device miscellaneous can satisfy the requirement of Workpiece clamping to a certain extent, but owing to belonging to non-standard apparatus, often need according to product construction characteristics, working condition and actual needs self design, not necessarily be fit to and other people use, therefore can not relax the exploitation of clamping device, present a lot of clamping devices also exist complex structure in addition, not easy to operate, to the operator require highly, device is complicated, the problem that cost is higher.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of clamping device simple in structure, easy to operate, lower-cost.
In order to solve the problems of the technologies described above, the invention provides clamping device in a kind of rotation, include the jig main body of cylindricality, described jig main body circumferentially is hinged with the equally distributed claw of a circle, described claw is around the jig main body radial rotating, its driven end is used for the endoporus of clamping work pieces, its drive end offsets with the cam ring lower limb that is socketed on the jig main body, the cam ring top edge cooperates with a bulge loop horizontal slip on being arranged on jig main body, the cam ring lower limb is provided with the cam that offsets with the claw drive end, and the cam ring outer rim is provided with the hole of grafting handle.
Adopt the interior clamping device of rotation of technique scheme to have following advantage: 1, because device mainly includes the jig main body of cylindricality, described jig main body circumferentially is hinged with the equally distributed claw of a circle, described claw is around the jig main body radial rotating, its driven end is used for the endoporus of clamping work pieces, its drive end offsets with the cam ring lower limb that is socketed on the jig main body, the cam ring top edge cooperates with a bulge loop horizontal slip on being arranged on jig main body, the cam ring lower limb is provided with the cam that offsets with the claw drive end, the cam ring outer rim is provided with the hole of grafting handle, construct fairly simple, simple to operate, only handle need to be inserted the hole of cam ring outer rim during clamping, the rotating cam ring is so that the drive end of the cam of cam ring lower surface extruding claw, thereby makes the endoporus of the driven end extruding workpiece of claw realize clamping, and unclamp the beginning, only need the backward rotation cam ring, the drive end that makes the cam of cam ring below no longer push claw gets final product, and is easy to operate; 2, because simple structure, so the processing and manufacturing cost is lower.
As preferred version, for so that the clamp force distribution of claw is more even, more fastening to the workpiece clamping, described claw is provided with 3.
As preferred version, for so that handle when the position of being inconvenient to exert oneself, can be readjusted handling position, the hole of described grafting handle evenly is provided with 6.
Description of drawings
Fig. 1 is the structural representation of clamping device in the embodiment of the invention rotation.
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 clamping device in a kind of rotation, include the jig main body 1 of cylindricality, jig main body 1 circumferentially is hinged with the equally distributed claw 2 of a circle, claw 2 is around jig main body 1 radial rotating, its driven end is used for the endoporus of clamping work pieces, its drive end offsets with cam ring 3 lower limbs that are socketed on the jig main body 1, cam ring 3 top edges cooperate with bulge loop 4 horizontal slips on being arranged on jig main body 1, cam ring 3 lower limbs are provided with the cam that offsets with claw 2 drive ends, cam ring 3 outer rims are provided with the hole 5 of grafting handle, and claw 2 is provided with 3, and the hole 5 of grafting handle evenly is provided with 6.
Above-described only is preferred embodiment of the present invention, should be pointed out 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 can not affect effect of the invention process and practical applicability.
Claims (3)
