Detailed description of the invention
The technical scheme that the present invention will provide is that a kind of pallet that is applied to engine production technique, comprises tray substrate 1 and support column, instituteState tray substrate 1 lower surface and be provided with articulated link mechanism, described tray substrate 1 is connected with engine line hinge by described articulated link mechanismConnect; Between described tray substrate 1 and described support column, be provided with lateral displacement system, described lateral displacement system comprises slide plate assembly and line slideway 2,The glide direction of described slide plate assembly is vertical with the traffic direction of described pallet on production line, and described slide plate assembly comprises left skateboard 3 and right slide plate 4,Between described left skateboard 3 and right slide plate 4, be provided with hinge linkage assembly 5, the relative distance between described left skateboard 3 and right slide plate 4 is passed throughDescribed hinge linkage assembly 5 regulates. Described support column comprises left skateboard 3 support columns and right slide plate 4 support columns, described left skateboard 3 support columnsMounting arrangements is on described left skateboard 3, and described right slide plate 4 supports mounting arrangements on described right slide plate 4.
Described support column is provided with steady pin installing plate, and described steady pin installing plate is provided with steady pin. Described left skateboard 3 and right slide plate 4 are respectivelyBe fixed on described line slideway 2 by screw. Described hinge linkage assembly 5 is by short connecting rod, long connecting rod, and axis pin base, connects bearing pin, shortBearing pin, fixed pin shaft composition.
Described fixed pin shaft is directly fixed on described tray substrate 1 by screw thread. Described long connecting rod is arranged on fixed pin shaft. Described short connecting rodBe connected with long connecting rod by described short pin shaft. Described hinge linkage assembly 5 is connected with described left skateboard 3 by described connection bearing pin, by instituteStating axis pin base is connected with described right slide plate 4.
Technical solution of the present invention comprises line slideway 2. Be fixed on original pallet by screw, can make sleeve mechanism easily move along straight line.
Technical solution of the present invention comprises right side slide plate assembly, by right slide plate 4, and support column, alignment pin installing plate, alignment pin composition. Slide plate is logicalCrossing screw is fixed on line slideway 2. Two support columns are fixed on slide plate. Alignment pin installing plate is fixed on support column. Alignment pin is placed in fixedOn the pin installing plate of position.
Technical solution of the present invention comprises dead gear limited block. Be screwed on former pallet the aperture of restriction sleeve mechanism.
Technical solution of the present invention comprises closed position-limit mechanism assembly, by handle ball, and last item, last item guide holder, stroke limit piece, spreading pressing plate,Spring, spacer pin guide holder, spacer pin composition. Spacer pin guide holder and spacer pin are arranged on tray substrate 1. Remainder is arranged on left skateboardOn 3.
Closed position-limit mechanism is mainly used in accurately controlling the closing position of sleeve mechanism. When sleeve mechanism is in expanded position, when off position.Spreading pressing plate is pushed down spacer pin. Stroke limit piece prevents that last item from dropping out.
While needing closure, cylinder promotes left skateboard 3 and moves forward. In the time that the dowel hole on it moves to the position of spacer pin. Spacer pin loses pressure,Under the effect of spring, insert in the dowel hole of left skateboard 3. Thereby sleeve mechanism is locked. While needing tripping-gear, manually utilize handle ball gramTake spring force and press last item, spacer pin is pressed out from the dowel hole of slide plate to latch-release.
Technical solution of the present invention comprises left side slide plate assembly, by left skateboard 3, and support column, locating piece composition. Left skateboard 3 is fixed on straight line and leadsOn rail 2. Support column is fixed on slide plate. Locating piece is arranged on support column, for placing engine.
Technical solution of the present invention comprises steel-ball limiting assembly, by steel-ball limiting plate, and steel ball, spring, steel ball seat composition. Steel-ball limiting plate spiral shellNail links together with steel ball seat, and steel ball and spring are placed in the endoporus of steel ball seat. The whole series are spacing to be fixed on tray substrate 1 by steel ball seat.
Steel-ball limiting is mainly used in preventing that slide plate 4 assemblies in left and right are automatically closed. In the time that left skateboard 3 is expanded to relevant position, steel ball is at the work of springWith under head in the corresponding shrinkage pool of left skateboard 3, thereby latched position. Due to the unique design of steel-ball limiting plate structure, make the steel ball can be very lightIn the shrinkage pool of ground turnover left skateboard 3. Therefore, steel-ball limiting assembly is used in combination restriction deployed condition with dead gear limited block. While needing closure, only needApplying very little external force just can be easily closed.
Technical solution of the present invention comprises hinge linkage assembly 5, by short connecting rod, and long connecting rod, axis pin base, connects bearing pin, short pin shaft, GuRationed marketing axle composition.
Rationed marketing axle is directly fixed on tray substrate 1 by screw thread. Long connecting rod is arranged on fixed pin shaft. Short connecting rod is by short pin shaft and long connecting rodConnect. Between bearing pin and connecting rod, be matched in clearance, can freely rotate. A whole set of connecting rod is by connecting bearing pin and axis pin base and left and right slide plate 4 evenConnect.
Hinge linkage is key mechanism of the present utility model, is the hinge that connects left and right slide plate 4 assemblies. Can make left and right slide plate 4 by itAlways be shaped as interlock, launch with closed with identical speed.
