Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1 and Fig. 2, upper as can be seen from figure, the utility model is used for the driving mechanism of two-way clamping, and comprise mount pad 1, be provided with rectangular enclosure on mount pad 1 surface, in cavity, two ends are symmetrically installed with rotating shift fork 3 respectively by declutch shift shaft 2.In the middle part of cavity floor, be provided with center hole, be provided with the shift fork guiding plug 4 that can slide up and down in center hole, shift fork guiding plug 4 upper end is arranged in cavity, and shift fork guiding plug 4 is in the active shift fork slot 5 being circumferentially provided with ring-type of cavity segment.Be provided with actuating unit in mount pad 1 bottom surface, actuating unit and the shift fork plug 4 that leads is connected and centrally moves up or down in hole with the shift fork plug 4 that leads.One of them shifting block of two shift forks inserts in active shift fork slot, and another shifting block of two shift forks performs member acts as the driving head performing component separately to drive.
Particularly, another shifting block of two shift forks 3 is driven by slide block 6 and performs component 8 action, chute is provided with on the surface at mount pad 1, trough width is greater than cavity width, slide block 6 is located in chute and also can be horizontally slipped along chute, slide block 6 bottom surface is respectively equipped with passive shift fork jack 7, and another shifting block of shift fork 3 inserts in passive shift fork jack 7, and described execution component 8 is removably mounted on slide block 6.Described execution component 8 is for by the chuck of Workpiece clamping or claw, and two chucks or claw are oppositely arranged.
During work, actuating unit shift fork guiding plug 4 centrally moves down in hole, moving down of shift fork guiding plug 4 drives shift fork 3 to center rotating, because shift fork 3 is connected with slide block 6 passing hole, so slide block 6 under the transmission of shift fork 3 along chute slide in opposition, be arranged on slide block 6 owing to performing component 8, therefore perform component 8 also relative motion symmetrically, thus workpiece is synchronously clamped.If the complete needs of work pieces process unclamp exit, now actuating unit shift fork guiding is filled in centrally hole and to be moved up certain distance, and course of action with clamping on the contrary.
Further, in the middle part of described slide block 6, upwardly form inverted T shape structure, perform component 8 and be arranged on protrusion surface; The both sides of every block slide block 6 are respectively equipped with pressing plate 9, and pressing plate 9 to be fixed on mount pad 1 and to be pushed down slide block 6 both sides.Such slide block just can not move up and down, and can only along chute side-to-side movement.So more convenient processing of structure simultaneously and fluting.
Described execution component 8 is arranged on slide block 6 protrusion surface by mounting blocks 10, is provided with vertical adjustable plate 11 in slide block 6 outer face, and adjustable plate 11 is fixed by bolt and slide block 6.Adjustable plate 11 is provided with adjusting bolt 12 simultaneously, and adjusting bolt 12 passes adjustable plate 11 and is against mounting blocks 10 end face.Make the distance of slide block movement limited because shift fork rotates, namely the adjustable range between slide block is limited, may not meet the clamping needs of the larger workpiece of some size difference, this structure changes the spacing of mounting blocks further by adjusting bolt, and this spacing determines the minimum and maximum spacing of chuck.Namely the adjustable range of chuck is shift fork adjustable range and adjusting bolt adjustable range sum, can be practically applicable to the need of different size workpiece like this.If workpiece is pipe, so this device just can have larger accommodation to the external diameter of pipe.
The both ends of the surface that two slide blocks 6 are relative are provided with symmetrical draw-in groove 13, baffle plate 14 cover on shift fork guiding plug 5, baffle plate 14 two ends are stuck in draw-in groove 13.The design of the draw-in groove degree of depth, to make baffle plate can not come off from draw-in groove, no matter slide block is in maximum spacing or minimum spacing.During actual clamping, circular pipe workpiece just can directly be placed on baffle plate, and baffle center position arranges a groove, and pipe can be avoided to be in place rear rolling.Shift fork guiding plug hides by baffle plate, avoid processing the iron produced to cut etc. enter shift fork guiding plug place cavity in because this may bring clamping stagnation to moving up and down of shift fork guiding plug.
Described actuating unit can be stepper motor, and also can be hydraulic mechanism, hydraulic mechanism comprises oil cylinder and piston, drives shift fork guiding plug to move up and down by moving up and down of piston.
The utility model drives two to perform component move toward one another by a set of actuating unit dexterously, and can realize the clamping to workpiece with dynamics, locating effect is better simultaneously.Can be convenient for changing on slide block owing to performing Components installation, to adapt to the clamping needs of different workpieces, flexibility is good.
This execution component distance controllability is large, both can be regulated by shift fork, and also can be regulated by the adjusting bolt on adjustable plate, can adapt to the workpiece that size span is large, versatility is better.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
