Track is included, several assembling sub-platforms being arranged side by side and can slide along track, the assembling sub-platform packet are set on the track
Crossbeam is included, two automatic clamping devices in left and right are provided on the crossbeam；The automatic clamping device includes being connected by pin shaft
Left claw and right pawl, the pin shaft are connected on the drive rod that is vertically arranged of lower section, so that pawl is also therewith when drive rod is gone up and down or so
Opening and closing；The spring for reset is provided with below the drive rod.Left claw and right pawl are connected using pin shaft, enable the two around
It is stirred inside and outside pin shaft.Due to the presence of spring, so that usually drive rod is jacked up, left and right pawl turns up opening.And when sand core is pressed on
When in pawl, drive rod decline, interior receive of left and right pawl realizes self-holding function.
As an improvement the automatic clamping device further includes the L shape support frame for connecting with crossbeam, the support
Mounting box is fixed on frame；Guide groove is provided on the mounting box, the drive rod and spring are set in guide groove.Guide groove
Width with driving shank diameter it is consistent, avoid drive rod radial-play.
As an improvement being provided with guide post below the left claw and right pawl, the guide post is inserted on mounting box
In pilot hole, the division for specification left and right pawl is acted.
As a kind of further improvement, further includes the lid for closing guide groove, be provided with limit hole on the lid；
The limited post through limit hole is fixed on the drive rod.The scope of activities of drive rod is limited, avoids it by spring
Pop up guide groove.
As another further improvement, it is provided on the transverse slat and riser of support frame as described above several for adjusting position
The long hole set；And support frame back is provided with stiffening plate.It is provided with several screw holes being axially arranged on crossbeam, is bolted
Long hole and screw hole enable the position of support frame easily to adjust.And the height that the long hole on riser is used to adjust left and right pawl is used
In the sand core of cooperation different model.
As an improvement being provided with positioning convex platform, the left and right two between the automatic clamping device of the left and right two
Positioning slide plate is provided on the outside of automatic clamping device.For positioning sand core.
As an improvement the crossbeam bottom is provided in the sliding slot of track cooperation；It further include for driving crossbeam to exist
The driving device slided on track.
As an improvement further including the rack gear with parallel track, the driving device includes the gear with rack gear cooperation
And the shaft of sliding tooth wheel rotation.Entire assembling sub-platform can be driven using the rotation of handle drives shaft to move forward and backward.Benefit
Brake positioning is easier with rack pinion cooperation.
The large-scale sand core positioning and clamping platform having the beneficial effect that with above structure of the utility model, substitution tradition
Lifting splicing, sand core assembling when will not shake, improve the accurate of splicing.Sand core falls on assembly platform under simultaneously
By Automatic-clamping when upper, its movement was avoided, artificial regular time has been saved, has provided production efficiency significantly, improved product
Quality.
