Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-3, workpiece quick positioning clamp of the present utility model comprises matrix 1 and flipping block 2, described flipping block comprises and being integrally formed and the pressing plate 21 arranged in acute angle or right angle and push pedal 22, described pressing plate and the medial surface of push pedal are provided with circular arc respectively highlightedly and touch face 23, column roller bearing 24 is respectively arranged with in the outside of described pressing plate and push pedal intersection, the hole slot 11 of pressing plate described in permission and push pedal upset is formed in the middle part of described matrix, the groove 12 mated with described roller bearing is set in described hole slot both sides, simultaneously, the convex tongue 13 that can mate and insert table positions groove is provided with in the bottom of described matrix.Wherein, also comprise and to be fixedly connected with being positioned at by roller bearing in groove with substrate and limited block, the lateral surface 18 of described hole slot is that inclined-plane is to locate outside push pedal.Pressing plate simultaneously and the medial surface of push pedal intersection are provided with inner groovy 25 to avoid interfering.Do not suppress for ease of workpiece and lift pressing plate and be in top, be provided with magnetic block between described push pedal lateral surface top and matrix or extension spring tilts to make its free state lower platen.Coordinate magnet piece or extension spring by the inclined design of hole slot, can ensure that briquetting is in optimum position, when workpiece falls, play best self-align effect.
Specifically, positioning fixture of the present utility model, utilize bascule principle, when large-scale workpiece drops on pressing plate under Primary Location guides, along with falling of workpiece, the circular arc contact surface of push pedal can contact with the lateral surface of workpiece, and when the falling further of workpiece, effect by lever produces an inside thrust, and active force may be used for jam-packed workpiece from the side, realizes the meticulous self-adjusting of a position.When specifically using, according to pre-aligned good this automatic positioning clamp several of the shape of workpiece, getting final product a step and realizing meticulous location, ensure that the required precision of following process, greatly improving efficiency simultaneously.
Further, for improving the stability of automatic positioning clamp, presenting a theatrical performance as the last item on a programme in order to depression bar contact is provided with in described matrix upper surface both sides, this fixture is fixed by the depression bar coordinated with workbench, simple to operate, and utilize formula reserved location design of presenting a theatrical performance as the last item on a programme, the convenience that arranges of depression bar is promoted further.
Further, described both sides, rear portion, matrix bottom surface are provided with caulking groove 16, and the convex tongue 13 that can snap in matchingly in described caulking groove is fixedly connected on described caulking groove place by bolt and alignment pin.Namely this convex tongue positions mainly through alignment pin, bolt is only prevent from departing from, alignment pin one end is stuck in the T-slot of platen, one end is stuck in the bottom of matrix, this convex tongue is used for fixing of matrix and platen, that alignment pin can not be split away off from matrix by the object that convex tongue and matrix are tightened by bolts, wherein, making interchangeable alignment pin is that the reason of syndeton is to be convenient to change, what the utility model quick clamping device the most easily wore and tore is exactly column roller bearing and these alignment pins, column roller bearing can be increased the service life by surfaces nitrided technique, but this alignment pin can only take hardness, and lower material makes, avoid the T groove damaging platen.Make interchangeable object and be just this, need easily to change when changing alignment pin.
Further, the upper surface of described matrix is formed with forward the boss 14 supporting workpiece highlightedly, described boss front portion is provided with through hole 15, workpiece is fixedly connected with matrix by the bolt running through through hole setting from described boss bottom from bottom to top, the lower surface certain distance of described boss distance matrix provides operating space to the setting of bolt, all boss upper surfaces used on the same device require it is identical height, object ensures that the workpiece bottom that boss supports with it is plane, prevent the workpiece of clamping from tilting, cause the part that processes defective.For different workpiece or different retaining parts, may correspond to the boss that different length is set and the bolt that setting is mated with the bolt hole of workpiece on boss, this positioning fixture and workpiece are bolted and are integrated, enhance the stability of connection, simultaneously, connection by bolt also can the precision of detection and location, prevents workpiece from loosening in process, ensures that following process does not occur error.
Specifically, be protection workbench and workpiece, described matrix and spill spin block adopt S50C steel to make, and wherein, the side face of circular arc contact surface and roller bearing are provided with nitriding layer.What take on namely on circular arc contact surface and roller bearing is Nitrizing Treatment technique (being commonly called as nitrogenize), in degree of depth 0.2mm top layer after nitrogenize, hardness is HV650, arc surface can not be burnt when stressed, and wherein burn refers to the phenomenon of the surface damage that a kind of heating that the steel material close to same rigidity produces under the effect of larger frictional force causes.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
