Abstract
The utility model relates to a clamping device, in particular to a cam multi-point clamping device. The cam multi-point clamping device comprises a base, a cam plate, a rotating shaft, a rotating handle and clamping arms with clamping heads at one ends. The rotating shaft is fixedly connected with the center of the bottom of the cam plate. The rotating handle is perpendicular to the rotating shaft and is fixedly connected with the rotating shaft. A plurality of sets of the clamping arms with the middle portions hinged to the base are arranged. Force exertion sections corresponding to the lower ends of a plurality of sets of the clamping arms respectively are arranged on the edge of the cam plate. According to the cam multi-point clamping device, a plurality of rocker arms can clamp work-pieces synchronously and stably.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of cam multiple spot clamping device.
Background technology
In machine tooling, conventionally after need to using clamp mechanism that workpiece is fixing, carry out again follow-up processing, so clamp mechanism is widely used in workpiece manufacture field, and existing clamp mechanism shortcoming is: when by a common holding workpiece of the multiple pressing plates of power drive, each pressing plate clamping work pieces is asynchronous, so easily cause clamping unstable.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of cam multiple spot clamping device, synchronously holding workpiece of multiple rocking arms of this clamping device, holding workpiece is more stable.
For achieving the above object, the technical solution of the utility model is: cam multiple spot clamping device, comprise pedestal and cam disc, wherein, the clamping limb that is also provided with rotating shaft, handler and one end band clamping head, described rotating shaft is fixedly connected with cam disc bottom centre, and described handler vertical rotation axle is also fixedly connected with it, be provided with many groups middle part and be articulated with the clamping limb on pedestal, cam disc edge has the multistage corresponding application of force section that promotes many groups clamping limb lower end respectively.
While adopting technique scheme, workpiece is positioned over to the upper surface of cam disc, pull handler, handler drives the turning cylinder being fixedly connected with it to rotate, and meanwhile, the cam disc being fixedly connected with turning cylinder rotates thereupon, the application of force section at cam disc edge outwards promotes clamping limb, because clamping limb middle part is articulated with on pedestal, thus clamping limb clamping head one end to lower swing, from top by piece-holder.The application of force section that on cam disc of the present utility model, multistage is identical is corresponding many group clamping limbs respectively, and when cam disc rotates, the application of force section that multistage is identical outwards promotes respectively many group clamping limbs, so clamping limb can be synchronously by piece-holder.
Further, every group of clamping limb lower end is equipped with adjusting screw(rod), can adjust adjusting screw(rod) according to the thickness that regulates workpiece, to clamp the workpiece of different size.
Further, along cam disc, three groups of clamping limbs are circumferentially equidistantly set, and cam disc edge correspondence is provided with three sections of application of force sections, the edge of described application of force section is one section of arc that radius increases gradually, three groups of clamping limbs arranging like this can be on workpiece the even application of force; Application of force section is cam structure, and energy self-locking when holding workpiece, without continue the application of force on handler.
Further, described cam disc upper surface is provided with locating slot, workpiece can be positioned in predetermined locating slot, and clamping limb carries out the application of force in the position of workpiece symmetry, and clamping is stable.
brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model cam multiple spot clamping device embodiment.
Detailed description of the invention
As shown in Figure 1, a kind of cam multiple spot clamping device, comprise pedestal and cam disc 1, wherein, also be provided with rotating shaft, the clamping limb 4 of handler 2 and one end band clamping head, rotating shaft is fixedly connected with cam disc 1 bottom centre, handler 2 vertical rotation axles 3 are also fixedly connected with it, be provided with three groups of middle parts and be articulated with the clamping limb 4 on pedestal, three groups of clamping limbs 4 are along the circumferential equidistant placement of cam disc 1, clamping limb lower end is equipped with adjusting screw(rod) 5, cam disc 1 edge has three sections of corresponding application of force sections that promote three groups of clamping limb 4 lower ends respectively, the edge of application of force section is one section of arc that radius increases gradually, cam disc 1 upper surface is provided with the locating slot of place work piece 6.
Specific works flow process:
As shown in Figure 1, be illustrated as clamping limb 4 holding workpiece 6 states.Workpiece 6 is positioned in the locating slot of upper surface of cam disc 1 and pulls counterclockwise handler 2, handler 2 drives turning cylinder 3 de-rotation that are fixedly connected with it, simultaneously, the cam disc 1 being fixedly connected with turning cylinder 3 is rotated counterclockwise thereupon, the application of force section at cam disc 1 edge and clamping limb 4 contact portions go to by the little side of radius the side that radius is large, thereby cam disc 1 edge outwards promotes clamping limb 4, because clamping limb 4 middle parts are articulated with on pedestal, so clamping limb 4 clamping head one end, to lower swing, clamp from top by workpiece 6.Pull clockwise handler 2, the application of force section at cam disc 1 edge and clamping limb 4 contact portions go to by the little side of radius the side that radius is large, put on the outside thrust of clamping limb 4 and disappear, and workpiece 6 can be taken out.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of 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 affect effect and practical applicability that the utility model is implemented.
