Abstract
The invention relates to a clamping device, in particular to a pneumatic wedge-block clamping device. The pneumatic wedge-block clamping device comprises a base, an air cylinder, a pressing plate provided with a clamping head, and a wedge block with the lower portion provided with an inclined surface. A piston rod of the air cylinder is fixedly connected with the upper end of the wedge block. The middle of the pressing plate is hinged to the base. The pneumatic wedge-block clamping device is further provided with an ejector rod, wherein the ejector rod is fixedly connected with the end, far away from the clamping head, of the pressing plate. The ejector rod is connected with the base in a sliding mode. The end, close to the wedge block, of the ejector rod is provided with an idler wheel which is in contact with the inclined surface. A reset spring is arranged between the bottom end of the pressing plate and the base. When the pneumatic wedge-block clamping device is used, the friction of the wedge block is small, and therefore the service life of the pneumatic wedge-block clamping device is prolonged.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of pneumatic tapered wedges clamping device.
Background technology
The clamping device overwhelming majority who uses in jig utilizes inclined-plane to change the thrust of voussoir into clamping force to carry out clamping work pieces, wherein the most basic form is exactly directly to utilize bevelled voussoir, and eccentric wheel, cam, screw etc. are all the distortion of voussoir.Wedge is reinforcement and locking element the most basic in clamping device, and wedge clamping device is to utilize the inclined-plane on voussoir directly or indirectly to wait Workpiece clamping.
Existing wedge block clamping device directly contacts by two inclined-planes, and in license notification number a kind of wedge clamping device that is CN203062611U, between movable block and tapered wedges, wedge surface coordinates, by the extruding of sliding between the two, thus clamping work pieces.This is that between the movable block of inclined-plane contact and tapered wedges, frictional force is large, easily wearing and tearing by the inclined-plane problem that directly clamping device of contact exists.
Summary of the invention
The defect existing for above-mentioned prior art, the object of the present invention is to provide a kind of pneumatic tapered wedges clamping device, and this clamping device in use, less to the friction of tapered wedges, so extend the service life of energy clamping device.
For achieving the above object, technical scheme of the present invention is: gas tapered wedges clamping device, comprise pedestal, cylinder, there is the pressing plate of clamping head and the tapered wedges that inclined-plane is established in bottom, the piston rod of described cylinder is fixedly connected with tapered wedges upper end, described pressing plate middle part is hinged with pedestal, wherein, is also provided with the push rod being fixedly connected with pressing plate clamping head far away one end, described push rod and pedestal are slidably connected, and the nearly tapered wedges of push rod one end is provided with the roller contacting with inclined-plane; Between described pressing plate bottom and pedestal, be provided with back-moving spring.
While adopting technique scheme, when the piston rod of cylinder promotes tapered wedges downwards, tapered wedges puts on component downward on roller rolls roller, the horizontal component putting on roller moves horizontally the push rod being connected with roller, now, push rod promotes pressing plate clamping head far away one end, and pressing plate rotates around pin joint, then clamping head clamping work pieces.In the present invention, adopt roller to contact with the inclined-plane of tapered wedges, friction is between the two rolling friction, and frictional force is very little, so can effectively extend the service life of clamping device.
Further, the pedestal of a relative side on described tapered wedges inclined-plane is provided with directive wheel, and in the slope driving roller process of tapered wedges, both relativity power is larger, so tapered wedges can just move towards inclined-plane rightabout, directive wheel can effectively limit just moving of tapered wedges.
Further, described push rod is threaded with pressing plate, and both are threaded and are convenient to dismounting, so maintenance or replacing push rod and pressing plate are more convenient.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the pneumatic tapered wedges clamping device of the present invention embodiment.
The specific embodiment
As shown in Figure 1, a kind of gas tapered wedges clamping device, comprise pedestal, cylinder 1, there is the pressing plate 5 of clamping head 51 and the tapered wedges 2 that inclined-plane is established in bottom, the piston rod 11 of described cylinder 1 is fixedly connected with tapered wedges 2 upper ends, described pressing plate 5 middle parts and pedestal are hinged, wherein, also be provided with the push rod 4 being connected with pressing plate 5 clamping head 51 threaded one ends far away, described push rod 4 is slidably connected with pedestal, and push rod 4 nearly tapered wedges 2 one end are provided with the roller 3 contacting with inclined-plane, on pedestal, be also provided with directive wheel 7, and directive wheel 7 with roller 3 in the relative both sides of tapered wedges 2, described pressing plate 5 bottoms are fixed with connecting pin, between connecting pin and pedestal, be provided with back-moving spring 6, for unclamping of pressing plate 5 clamping heads 51.
The concrete flow process of using:
Figure 1 shows that clamping head 51 is in clamp position.When the air admission hole on cylinder 1 top enters Compressed Gas, Compressed Gas promotes piston and piston rod 11 moves down, piston rod 11 promotes tapered wedges 2 downwards simultaneously, tapered wedges 2 puts on component downward on roller 3 rolls roller 3, and the horizontal component putting on roller 3 moves right push rod 4 levels that are connected with roller 3, now, push rod 4 promotes pressing plate 5 clamping head far away 51 one end, pressing plate 5 rotates counterclockwise around pin joint, clamping head 51 clamping work pieces then, and the back-moving spring 6 of pressing plate 5 bottoms is stretched; When the air admission hole of cylinder 1 bottom enters Compressed Gas, Compressed Gas promotes to move on piston and piston rod 11, and piston rod 11 upwards pulls tapered wedges 2 simultaneously, now, the back-moving spring 6 that pressing plate 5 bottoms are stretched pulls connecting pin, and pressing plate 5 clockwise rotates, and clamping head 51 unclamps workpiece.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of 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.
