A horizontal through and two longitudinal holes are arranged in the casing, the two longitudinal holes extend to the horizontal through hole from the upper portion of the casing, a cam shaft is arranged in the horizontal through hole, two ends of the cam shaft are limited through location parts, one end of the cam shaft extends out the casing, the rotating handle is arranged at the end, extending out the casing, of the cam shaft, the jack-props are respectively arranged in the two longitudinal holes, the lower ends of the jack-props abut against the cam shaft, and the upper ends of the jack-props abut against a work piece. By means of the technical scheme, the double-floating cam jack-prop clamping device can be used for clamping the work piece and is simple to operate, high in using flexibility and low in cost.
Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to the two unsteady fore-set clamping devices of a kind of cam.
Background technology
Anchor clamps are important process equipments indispensable in the machinery manufacturing industry, can guarantee mechanical processing quality, enhance productivity, reduce production costs, reduce labor intensity.
In the process of reality, the shape and structure of workpiece is ever-changing, for heteroid workpiece designs corresponding with it anchor clamps, is mechanical field staff's long-range mission.Though nipper offers convenience to machine-building,, it still exists following deficiency in the actual use: 1, common anchor clamps are only at specific workpiece, and usage is single, use flexibility ratio not strong; 2, common anchor clamps are one-body molded, the part replacement inconvenience.
The utility model content
The technical problems to be solved in the utility model provides a kind of more time saving and energy saving, uses the two unsteady fore-set clamping devices of the low cam of flexibility height and cost.
In order to solve the problems of the technologies described above, the utility model provides a kind of cam two unsteady fore-set clamping devices, include shell, camshaft, turning handle and fore-set, wherein, a cross through hole and two vertical holes are arranged in the shell, cross through hole is led to from shell upper in two vertical holes, camshaft is placed in the cross through hole, two ends limit the position by keeper makes it can only axial float and rotation, wherein an end stretches out shell and the round pie turning handle is installed, fore-set is placed in respectively in two vertical holes, and its lower end and camshaft offset, and upper end and workpiece offset, described fore-set moves up and down by the rotation of camshaft, compress simultaneously to reach at 2, float about by the axial float of camshaft, adapt to various nonplanar workpiece; In order to limit the fore-set direction of motion and to prevent that fore-set from deviating from, top, the vertical hole of shell is furnished with the adapter sleeve with its threaded engagement, be with stage clip on the described fore-set respectively, the fore-set bottom is provided with a circle projection and the stage clip lower end offsets, and the adapter sleeve in the upper end of stage clip and the vertical aperture of shell offsets.
The two unsteady fore-set clamping devices of this cam are adjusted the upper-lower position of two fore-sets by rotation and push-and-pull camshaft turning handle, thereby workpiece are carried out 2 even stressed compressing in conjunction with cam and the unsteady principle that compresses.
As preferred version, consider the attractive in appearance and practical of camshaft turning handle, in conjunction with mechanics, it is that rotation or push-and-pull are all stressed the most even that the turning handle of round pie uses, and seems that the comparison slyness is attractive in appearance, therefore described turning handle is selected round pie for use.
As preferred version, consider that the fore-set position needs restriction, and in the cash pledge process fore-set often wear and tear can influence service life and the operating accuracy of equipment, must in time change, so vertical aperture of shell is provided with the adapter sleeve restriction fore-set position of its threaded engagement and make things convenient for fore-set to change.
As preferred version, consider the convenience of the stressed even and operation of fore-set, spring can be realized to stressed buffering of fore-set and can fore-set be rebounded automatically at the cam lower, therefore is with stage clip at fore-set.
Adopt the thrust hold down gag of technique scheme to have following advantage: 1, because described camshaft can axial float, adjust the relative upper-lower position of two fore-sets thereby can float, therefore can adapt to various planes and on-plane surface workpiece, use flexibility ratio stronger; 2, because the vertical aperture of described shell is provided with adapter sleeve, therefore, after fore-set wearing and tearing, can change in time, easily and cost of manufacture lower.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the two unsteady fore-set clamping devices of the utility model embodiment cam.
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 cam two unsteady fore-set clamping devices, include shell 1, camshaft 2, turning handle 3 and fore-set 4, wherein, a cross through hole and two vertical holes are arranged in the shell 1, cross through hole is led to from shell 1 top in two vertical holes, camshaft 2 is placed in the cross through hole, two ends limit the position by keeper makes it can only axial float and rotation, wherein an end stretches out shell 1 and round pie turning handle 3 is installed, fore-set 4 is placed in respectively in two vertical holes, and its lower end and camshaft 2 offset, and upper end and workpiece offset, described fore-set 4 moves up and down by the rotation of camshaft 2, compress simultaneously to reach at 2, float about by the axial float of camshaft 2, adapt to various nonplanar workpiece; In order to limit fore-set 4 directions of motion and to prevent that fore-set 4 from deviating from, top, shell 1 vertical hole is furnished with the adapter sleeve 5 with its threaded engagement, be with stage clip 6 respectively on the described fore-set 4, fore-set 4 bottoms are provided with a circle projection and stage clip 6 lower ends offset, and the adapter sleeve 5 in the upper end of stage clip 6 and shell 1 vertical aperture offsets.
Concrete using method is: the two unsteady fore-set clamping devices of cam are placed the plane, workpiece is placed on the fore-set 4, adjust the potential difference up and down of two fore-sets 4 by push-and-pull camshaft 2, rotation by camshaft 2 realizes the compressing and unclamp of workpiece, the replacing that the keeper at camshaft 2 two ends can the convenient disassembly part.
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; should be considered as protection domain of the present utility model, these can not influence effect and practical applicability that the utility model is implemented yet.
