Illustrate that the present embodiment is applied to the assemble sequence of the dowel device of multi-vehicle-type lower body positioning below.
First, carrying weldment 102, Y-direction block 106, positive stop 503, lift cylinder 405 and breeches joint 601 are consolidated It is scheduled on column 101.Then, pin hook cylinder 304, linear bearing 7, lifting adapter 602 are installed on lower skateboard 402.Then, Vertical supporting plate 403 is installed on lower skateboard 402.Then, the upper mounting plate of combination pin (internal pin hook 301) will be assembled with 404 carry out X to translation, are then coordinated by pin-and-hole and are installed on vertical supporting plate 403.Then, it is limited block installing plate 501 is (attached Band limited block 502) it is installed on by pin-and-hole cooperation on vertical supporting plate 403.Then, breeches joint 601 and lifting are transferred with axle First 602 connection.Then, the lower end through hole insertion guide rod 401 opened up from the lower loading plate 103 of carrying weldment 102, after straight line Bearing 7, most at last in the upper end through holes that open up of upper loading plate 102a of the insertion of guide rod 401 carrying weldment 102, and locked with screw Tightly.
Illustrate below the present embodiment be applied to the dowel device of multi-vehicle-type lower body positioning positioning hole shape it is different and/ Or how body position of getting off is positioned and is stepped up when having deviation.
When the positioning hole shape of automobile lower body is different, or position of positioning hole is offset, pass through floor fixture digital-to-analogue pair The position of positioning hole and shape carry out three-dimensional coordinates measurement, and X is adjusted to adjust pad 104, Y-direction adjusting pad according to measurement result Piece 105, Z-direction adjust pad 204 and circular gasket a, and then realize the adjustment to round pin 201 and the X, Y, Z location of square cotter 202. Wherein, by adjusting circular gasket a, the Z-direction positional precision of round pin 201 is adjusted;By adjusting Z-direction adjust pad 204, adjustment side The Z-direction positional precision of pin 202.
To sum up, the elevating mechanism in the present embodiment and height limiting mechanism control different automobile types and cut in Z-direction height and position Change.Linear bearing 7 with guide rod 401 ensure that round pin 201 and square cotter 202 X to Y-direction positional precision.In addition, this implementation is set X is easy to three-dimensional coordinates measurement, quickly and easily adjustment circle to adjust pad 104, Y-direction adjust pad 105, Z-direction adjust pad 204 The positional precision of pin 201 and square cotter 202.
Guide rod 401 coordinates (H7/g6) with carrying weldment 102 gap, in the upper end screw lock of guide rod 401.Lifting In the presence of cylinder 405, lower skateboard 402 moves up and down along guide rod 401, and frictional force is small, is be easily moved, and stable movement, protects Demonstrate,proved combination pin (square cotter 202 and round pin 201) X to Y-direction positional precision.
It should be noted that by positioning finger setting, mode connects for screw, Stability Analysis of Structures between each part of the present embodiment.Each zero Part is substantially steel, and material is simple, easy to manufacture.
The dowel device that the present embodiment is applied to the positioning of multi-vehicle-type lower body includes round pin 201 and square cotter 202, round pin 201 in the second groove of square cotter 202, and round pin 201 and square cotter 202 are all located at least two pairs of pin hooks 301 of strainer The region that limits jointly of upper end in because pin hook 301 can be flared out in the presence of pin hook cylinder 304 or inwardly receive Tightly, therefore during tensioning with the round pin 201 in pushing pin hook 301 and square cotter 202 change in location can occur for pin hook 301, this When can carry out pinpointing grafting positioning in automobile lower body bottom due to round pin 201 and square cotter 202, therefore, the utility model leads to Cross the round pin of change in location and square cotter to be on the one hand adapted to automobile lower body be respectively that these are of different shapes for square hole and circular hole It positioning, on the other hand can meet the positioning needs of position degree deviation, and can be realized and be tensioned with itself, can be suitably used for different cars The conllinear mixes line production locating and machining of type, different parts.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
