The technical scheme of the utility model: many kinds engine mixed flow assembling upset chassis of the utility model comprises pedestal, drive part, rotating shaft; Be connected the rotating disk in the rotating shaft; Be installed in the clamp mechanism on the rotating disk; Its clamp mechanism comprises sliding way and the glide path of secured in parallel on rotating disk, is installed in the adjusting screw(rod) with bidirectional helical is installed on the screw rod fixed supported slab at slideway two ends, and left clamp and right clamp are installed on the adjusting screw(rod); Left side clamp and right clamp constrain between sliding way and the glide path, and an end of adjusting screw(rod) has rotating handle; At left clamp of correspondence and right clamp bottom the following fixedly fixture block that is fixed on the rotating disk is arranged.

Described rotating disk sidewall is established four guide slots, and the manual turntable retaining mechanism is installed at 90 ° of angles, four guide slot intervals on the pedestal stationary plane; The manual turntable retaining mechanism comprises the bearing pin installing hole that is fixed on pedestal stationary plane top; Bearing pin is installed in the bearing pin installing hole, and the middle part and the bearing pin of latch handle are hinged, and the front end of latch handle places in the groove of latch sidewall; Latch points to the rotating disk sidewall by the guide pad guiding; Have on the guide pad to apply pressure to the installing hole of spring of latch handle front end, spring locks it in compressive state by the step screw, makes the latch lower end be positioned at a guide slot on the rotating disk sidewall.

The advantage of the utility model

The fast fixture of the utility model can be connected clamping fast with the joint on the motor body, thereby realizes the quick conversion of different type of machines.Can accomplish the quick connection of multi-model, many specifications, multi-series engine.

The safety in order to guarantee fast, rotating disk is provided with the manual turntable retaining mechanism, and when turning device rotated to the technological angle that needs, the latch of manual turntable retaining mechanism sprang into rotating disk latch groove automatically, and realization technology attitude is accurately located; Behind the manual release latch, can continue to rotate to another technological angle that needs.

The utility model adapts to engine assembling process development requires and reaches 8 series, and discharge capacity is from 3.9L-13L, and power falls 545 horsepowers, different 3.66 times of big or small engine block product moment from 125 horsepowers.

The specific embodiment

Like Fig. 1, Fig. 2, Fig. 3, Fig. 4: many kinds engine mixed flow assembling upset chassis of the utility model comprises pedestal 1, drive part 2, rotating shaft 3; Be connected the rotating disk 4 in the rotating shaft 3; Be installed in the clamp mechanism on the rotating disk 4; Its clamp mechanism comprises the sliding way 5 of secured in parallel on rotating disk 4 and glide path 6, is installed on the screw rod fixed supported slab 11 at slideway two ends the adjusting screw(rod) 9 with bidirectional helical is installed, and left clamp 7 and right clamp 8 are installed on the adjusting screw(rod) 9; Left side clamp 7 and right clamp 8 constrain between sliding way 5 and the glide path 6, and an end of adjusting screw(rod) 9 has rotating handle; With right clamp 8 bottoms the following fixedly fixture block 10 that is fixed on the rotating disk 4 is arranged at the left clamp 7 of correspondence.

Adaptive quick attachment plug is installed on the cylinder body cooperates, guaranteed the safety butt joint of quick conversion type with clamp mechanism.

Through rotation adjusting screw rod 9, drive left clamp 7 and do counter motion with right clamp 8, left clamp 7 and right clamp 8 near the time, with fixing fixture block 10 down, realize clamping fast, otherwise realize discharging.

Like Fig. 2: rotating disk 4 sidewalls are established four guide slot 4a, and four guide slot 4a are 90 ° of angles at interval.

Like Fig. 1, Fig. 3, Fig. 4: the manual turntable retaining mechanism is installed on pedestal 1 stationary plane 1a; The manual turntable retaining mechanism comprises the bearing pin installing hole 12c that is fixed on the pedestal 1 stationary plane 1a; Bearing pin 12b is installed in the bearing pin installing hole 12c, and middle part and the bearing pin 12b of latch handle 12a are hinged, and the front end of latch handle 12a places in the groove of latch 12 sidewalls; Latch 12 points to rotating disk 4 sidewalls by guide pad 12d guiding; Have on the guide pad 12d to apply pressure to the installing hole of spring 12f of latch handle 12a front end, spring 12f locks it in compressive state by step screw 12e, makes latch 12 lower ends be positioned at a guide slot 4a on rotating disk 4 sidewalls.

Do not having external force to do the time spent, through step screw 12e locking and spring 12f active force, latch handle 12a drives latch 12 and inserts in rotating disk 4 guide slots 4, realizes directed.
