Description

A kind of core setting jig for casting that has the lifting frame

Technical field

The utility model relates to a kind of core setting jig for casting, especially can be applied on the high efficiency Foundry Production streamline, can reduce the core jig of core labour intensity under the workman.

Background technology

At present, on most of Foundry Production streamlines, following core operation can't realize mechanical automation.Following core process still is a core or use some simple and easy auxiliary core jigs to realize under the conventional a dead lift.Such process all exists hand labor intensity big usually, simple and easy fixture operation inconvenience, and core is easily damaged, the external form die cavity easily bumps shortcomings such as collapsing scarce, core and external form dislocation, causes foundry goods fleshiness, few meat, dislocation, defectives such as wall unevenness cause the cast product decrease in yield.

Summary of the invention

At the deficiencies in the prior art, the utility model provides for a kind of core setting jig for casting that has the lifting frame, problems such as scarce are run into, bumped to core and external form when overcoming the conventional operation of core down, and reduce working strength of workers effectively, thereby improve the quality that core precision down guarantees foundry goods.

The core setting jig for casting structure that the utility model has the lifting frame comprises guide housing and lifting frame, guide housing is the shaped as frame structure, lifting guide pillar and lifting guide pillar support are installed in guide housing top, alignment pin is installed in the guide housing bottom, the lifting frame is installed on the lifting guide pillar between the lifting guide pillar support of guide housing top, can slide up and down along lifting guide pillar, utilize lifting guide pillar to realize location and slide-and-guide; Jig arm is installed in the middle of the lifting frame drives cylinder, jig arm and suspension rod, they can move up and down with the lifting frame, keep the balance of anchor clamps.

The utility model has in the core setting jig for casting of lifting frame, and adopting an annular guide housing is fundamental parts, and 2 alignment pins are installed on the guide housing, in order to realize core jig and the external form sandbox location of placing the core assembly tire of core in advance or being about to place core; Secondly, four lifting guide pillar supports are installed on the guide housing, are installed in respectively on four angles of guide housing, four lifting guide pillars are installed between guide housing and lifting guide pillar support, the lifting guide pillar support is provided with the lifting frame up and down respectively and slides up and down stop surface, limits lifting frame sliding distance.The lifting frame is positioned at guide housing, determines its position in guide housing by lifting guide pillar, and utilization lifting power is realized independent up and down the slip, and determines its upper and lower dead-centre position by the upper and lower stop surface of lifting guide pillar support; The core jig arm is installed on the lifting frame, the clamping that realizes core by the effect that drives cylinder with unclamp, can follow the lifting frame when core is clamped and move up and down; Four suspension rods also are installed on the lifting frame, and an end of suspension rod is installed on the lifting frame, and the other end is installed on the hanger; Every suspension rod comprises a tension pipe and two pull bars, uses spiral marking connection between them, in order to regulate the balance of core jig when non-core clamped condition lifts by crane.

As another kind of improvement the of the present utility model, arrange on the lifting frame of described core jig that a balance weight and balance weight drive cylinder, balance weight is regulated the balance of core jig when the core clamped condition lifts by crane by the effect that drives cylinder.

The utility model has the advantages that: lifting frame and guide housing are skillfully constructed, compact conformation, can solve core group and sandbox location simultaneously, problem such as tilt during the core handling, the many shortcomings that overcome conventional artificial core down or brought with core under the simple lifting tool, and down core is easy and simple to handle, safe, with low cost, is more suitable in productive temp Foundry Production streamline core operational applications up and down faster.

The specific embodiment

Further specify the structure and the occupation mode of the utility model foundry goods core jig below in conjunction with accompanying drawing.

The utility model primary structure is connected and installed and is: lifting guide pillar support 2, lifting guide pillar 4 and alignment pin 5 are installed on the guide housing 1, lifting frame 3 is installed on the lifting guide pillar 4 that reaches on the guide housing 1 between the guide bar support 2, utilizes lifting guide pillar 4 to realize location and slide-and-guides; Jig arm drives cylinder 8 and jig arm 9, and balance weight 6 and balance weight drive cylinder 7 and be installed on the lifting frame 3, move up and down with lifting frame 3; Suspension rod 10 is installed on the lifting frame 3, realizes the pre-equilibration adjusting of anchor clamps and the priority motion of lifting frame 3 and guide housing 1; 4 suspension rods 10 are installed on the lifting frame 3, and suspension rod is made up of 11 and 2 pull bars 10 of tension pipe.

Embodiment of the present utility model is such: at first by being connected of boom hoisting and hanger 13, the anchor clamps of slinging are regulated the sub-assembly tension pipe 11 and pull bar 12 of suspension rod 10 again, and anchor clamps can not be tilted, and are in poised state.Anchor clamps descend then, by alignment pin 5, anchor clamps are cooperated with the core assembly tire location of placing core in advance, when the lower plane of guide housing 1 with after the core assembly tire contacts fully, guide housing 1 transfixion, and lifting frame 3 continues to move down along lifting guide pillar 4, lower position-arresting face until lifting frame 3 contacts fully with the lower position-arresting face of lifting guide pillar support 2, this moment, whole anchor clamps remained static, jig arm drives 9 motions of cylinder 8 driving jig arm and clamps cores, the anchor clamps balance when balance weight driving cylinder 7 driven equilibrium pieces 6 arrive the precalculated position with adjustment core clamped condition; Boom hoisting rises then, and lifting frame 3 and the core that clamps thereof move on lifting guide pillar 4, and with after the upper position-arresting face of guide bar support 2 contacts fully, guide housing 1 rises, whole anchor clamps disengaging core assembly tire until the upper position-arresting face of lifting frame 3.When anchor clamps carry the core arrival sandbox end face of clamping, anchor clamps descend, make anchor clamps cooperate the above process that repeats by alignment pin 5 with the sandbox location, different is after 3 declines of lifting frame put in place, jig arm drives 9 motions of cylinder 8 driving jig arm and unclamps core, balance weight drives cylinder 7 driven equilibrium pieces 6 resets balance weight, and whole then anchor clamps rise, and finish the working cycles of a following core.
