Abstract
The utility model relates to a clamping device, in particular to a positioning clamping device for a workpiecces with a hole. The positioning clamping device comprises a clamping platform, a clamping mechanism and a positioning pillar. The positioning clamping device further comprises a positioning plate arranged on the clamping platform, the positioning pillar is connected with the positioning plate, and the clamping mechanism comprises a clamping plate, clamping pins and a base connected to the clamping platform, the two sides of one end of the clamping plate are hinged to the base, and tension springs are arranged between the other end of the clamping plate and the base. The clamping pins are arranged on the face, close to the positioning pillar, of the clamping plate and can be used for clamping the workpiece. According to the clamping device, the positioning pillar and the tension springs are used for positioning and clamping the workpiece, so that resources are saved, and clamping force is small.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of positioning clamping device of workpiece with hole.
Background technology
In field of machining, all will be first by Workpiece clamping, some even also will be located workpiece, so positioning clamping device all will be set on grain-clamping table.Existing positioning clamping device is divided into hand-operated clamping and motor-driven clamping, and the power source of hand-operated clamping is manpower, the power source of motor-driven clamping be pneumatic, surge or electronic etc., current motor-driven clamping device uses comparatively extensive.
But for a workpiece that only needs simple positioning clamping, adopt the mode of motor-driven clamping not only to waste resource, and the larger chucking power of motor-driven clamping is easily by bad workpiece clamp.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of positioning clamping device of workpiece with hole, and this clamping device utilizes the power of extension spring as clamping work pieces, and saving resource and chucking power are less.
For achieving the above object, the technical solution of the utility model is: the positioning clamping device of workpiece with hole, comprise grain-clamping table, clamp mechanism and locating dowel, wherein, also comprise the location-plate being arranged on grain-clamping table, described locating dowel is connected with location-plate, described clamp mechanism comprises clamping plate, holding pin and is connected in the base of grain-clamping table, both sides and the base of described clamping plate one end are hinged, between the other end and base, be provided with extension spring, described holding pin is arranged at the nearly locating dowel one side of clamping plate above and can holding workpiece.
While adopting technique scheme, workpiece is positioned on location-plate, locating dowel runs through the hole of workpiece, now, pull clamping plate, clamping plate turn to a side of workpiece to be clamped around hinged end, extension spring pulls clamping plate downwards, and clamping plate free end puts on the component of level of side surface of workpiece and locating dowel jointly by piece-holder.The utility model utilizes the power of extension spring as clamping work pieces, locates by locating dowel, and clamping plate and locating dowel are jointly by piece-holder, so the utility model saving resource and chucking power are less.
Further, the upper holding pin of the nearly locating dowel of described clamping plate one side, clamping plate is during from side surface of workpiece holding workpiece, and holding pin props up workpiece from workpiece top, guarantees stable on vertical of workpiece.
Further, described clamping plate both sides are equipped with extension spring, and the extension spring of both sides makes clamping plate be cancelled towards the component of a side, guarantee the process stabilization of clamping plate in both sides upset.
Accompanying drawing explanation
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 positioning clamping device embodiment of the utility model workpiece with hole.
The specific embodiment
As shown in Figure 1, a kind of positioning clamping device of workpiece with hole 8, comprise grain-clamping table 1, clamp mechanism and locating dowel 3, wherein, also comprise the location-plate 2 being arranged on grain-clamping table 1, described locating dowel 3 is connected with location-plate 2, described clamp mechanism comprises clamping plate 5 and is connected in the base 4 of grain-clamping table 1, the upper holding pin 7 of described clamping plate 5 nearly locating dowel 3 one side in upper end, both sides and the base 4 of described clamping plate 5 one end are hinged, between the other end and base 4, be provided with extension spring 6, be not subject under the state of external force, extension spring 6 can only rest on the both sides of hinged place.In the present embodiment, clamping plate 5 both sides are equipped with extension spring 6, and described holding pin 7 is arranged at nearly locating dowel 3 one sides of clamping plate 5 above and can holding workpiece 8.
Specific works flow process:
As shown in Figure 1, workpiece 8 is positioned on location-plate 2, clamping plate 5, to complete the location of workpiece 8, now, is pulled clockwise in the hole that assurance locating dowel 3 runs through workpiece 8, clamping plate 5 turn to workpiece 8 one sides clockwise around hinged end, extension spring 6 pulls clamping plate 5 downwards, and clamping plate 5 is from the side application of force of workpiece 8, and clamping plate 5 and locating dowel 3 clamp workpiece 8 jointly, holding pin 7 in nearly locating dowel 3 one sides of clamping plate 5 is from the workpiece 8 upper surface application of forces, and restriction workpiece 8 is offset on vertical.
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.
