Based on said structure of the present utility model, below operation principle of the present utility model is introduced.
Under normal operating conditions, the locking rod 123 of locking unit 12 is engaged in the teeth groove of bevel gear 19 with certain thrust, so that bevel gear 19 can not rotate, the leading screw 16 of pallet 1 can not rotate, thus achieve the locking to guide rails assembling plate 100, namely guide rails assembling plate 100 remains unchanged when pallet 1 circulates in each station with the relative position of jig pallet 102, and then ensures that the workpiece 10 being fixed on pallet 1 position when each assembly station remains unchanged relative to the position of jig pallet 102.
Each assembly station has needed that from lower groove part, the part such as ball, spacer rod is loaded side end face and has loaded the space between upper and lower groove, for this, lower groove part loads the position of side end face (assembling base plane) need to keep consistent, that is, lower groove part loads side end face and need to keep consistent with the locus of pallet 1. For different workpiece, the distance that under slide rail, the location pitch-row of groove loads side end face from part is often different, and therefore, the distance that under slide rail, groove part loads between side end face and the end face of workpiece positioning seat 11 is often different.
In order to make the assembling base plane of each lower groove remain unchanged relative to the locus of pallet 1, then can pass through the distance adjusting workpiece positioning seat 11 relative to solving latch mechanism 3 and realize. when needing the position adjusting workpiece positioning seat 11 according to different workpieces, the piston rod of the second cylinder 33 solving latch mechanism 3 stretches out, solution latch mechanism installing plate 34 is driven to move towards pallet 1, so that the contact head 317 of measuring of displacement sensing system 31 contacts the measurement contact block 116 on workpiece positioning seat 11, the stretching out further of piston rod along with the second cylinder 33, measure the retard motion of contact head 317 and stop, and make kinematic axis 312 be extruded retrogressing, so that the 3rd spring 315 is compressed by trace, displacement transducer 311 senses compression, measure and measure contact block 116 apart from the distance solving latch mechanism installing plate 34, it is workpiece positioning seat 11 relative to the distance solving latch mechanism 3, thus can calculate lower groove part and load side end face (assembling base plane) relative to the distance with pallet 1, and then determine the required distance value adjusted of workpiece positioning seat 11, with the assembling base plane that realizes different slide rail relative to the locus of pallet 1 for steady state value. in solving the process that latch mechanism installing plate 34 moves towards pallet 1, solve the push rod 32 on latch mechanism installing plate 34 and contact the swinging axle 127 of locking unit 12, and promote swinging axle 127 to rotate around supporting axle 126, to retract locking rod 123, now the first spring 122 is compressed, releasing bevel gear 19 locking, leading screw 16 unlocks.
Then, the piston rod of the first cylinder 23 on the driving mechanism 2 of pallet 1 opposite side stretches out, driving mechanism installing plate 24 is driven to move towards pallet 1, outer-hexagonal driving head 221 first contacts interior hexagonal driving head 15, the piston rod of the first cylinder 23 stretches out further, so that outer-hexagonal driving head 221 is extruded retraction, now the second spring 222 is compressed, and utilizes spring force that outer-hexagonal driving head 221 presses closer interior hexagonal driving head 15; Now, motor 21 slowly rotates, and when the corner of outer-hexagonal driving head 221 and interior hexagonal driving head 15 is mated, under spring force, outer-hexagonal driving head 221 inserts in interior hexagonal driving head 15. Hereafter, motor 21 rotarily drives leading screw 16 and rotates, thus driving two workpiece positioning seats 11 to move, and measured its displacement by displacement transducer 311, when reaching setting value, the assembling base plane being under slide rail groove arrives steady state value relative to the locus of pallet 1, motor 21 stops operating, the piston rod of the second cylinder 33 solving latch mechanism 3 is retracted, locking unit 12 is under the effect of the first spring 122, locking rod 123 therein is stretched out, latch cones gear 19, and then the locking workpiece 10 position on pallet 1; Finally, the first cylinder 23 of driving mechanism 2 is retracted so that outer-hexagonal driving head 221 departs from interior hexagonal driving head 15.
In sum, advantage of the present utility model is as follows:
1) by automatically adjusting workpiece locus on pallet, it is achieved that under seat slide, groove part loads the locus unification of side end face (assembling base plane), is effectively simplified the design of each assembly station technological equipment;
2) elastic force of the first spring and the mode of screw pair are utilized, it is achieved that adjustment and the locking to chucking position; Realize the locking to screw pair drive end by elastic force, utilize the lock feature of reversely stopping of screw pair, it is achieved the secure ratcs to workpiece positioning seat;
3) introduce displacement transducer to achieve to be in course of adjustment and adjust the dynamic measurement of distance, define closed loop control, the precision of the adjustment greatly improved and efficiency;
4) adopt the mode that inside and outside hexagonal driving head coordinates to realize the transmission of driving force, it is ensured that the reliability of driving force transmission, and to the big adaptability transmitting moment of torsion.
Above-described, it is only preferred embodiment of the present utility model, is not limited to scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes. Namely every claims according to this utility model application and description are made change simple, equivalent and modification, fall within the claims of this utility model patent. The not detailed description of this utility model be routine techniques content.
