Abstract
The utility model discloses a supporting frame for a workpiece such as a lathe shaft. The supporting frame is provided by overcoming the defects that when the large workpiece such as shaft is turned on a lathe in the prior art, a crane is required to hoist the workpiece so that the workpiece can be precisely positioned and clamped directly on a chuck; the operation is time-consuming and labor-consuming; and the chuck is easy to collide during the positioning process and the turning precision of the lathe can be affected. A concave arc-shaped supporting tile that can support the workpiece such as shaft to be aligned to the central line of the chuck precisely is arranged on the supporting frame that is arranged on the upper surface of a guideway on a lathe body. As the crane can firstly hoist the workpiece such as shaft on the upper surface of the lathe guideway so that the workpiece such as shaft can be arranged on the concave arc-shaped supporting tile on the upper part of the base; therefore, the workpiece such as shaft is aligned to the central line of the chuck; the workpiece such as shaft is not directly hoisted into a chuck claw of the lathe by the crane; the crane does not need to be operated for leading the workpiece and the chuck to be precisely aligned to each other; therefore, the workpiece can be easily arranged on the concave arc-shaped supporting tile so that the chuck is not damaged and the turning precision of the lathe is not affected.
Description
Technical field
The utility model belongs to instrument, specifically a kind of bracing frame that the machining large shaft-like workpiece is used on lathe.
Background technology
With the common elongated shaft-like workpiece of lathe turning, generally be to hold workpiece to be machined during clamping, the one of which end is clamped on the pawl of chuck, the other end on the centre bore of axle head head, carries out turning with the thimble pinnacle of installing on the tail stock then.After machining, unscrew chuck jaw and live workpiece with hand rest again and unload.
The turning processing of removing motionless large-scale shaft workpiece for manpower need be transported near the chuck of lathe by the overhead traveling crane large-scale shaft workpiece of slinging, and the suspension hook position of adjustment overhead traveling crane leads workpiece in the clamp jaw of chuck with hand again, does to clamp after the accurate contraposition; Sling from lathe chuck with overhead traveling crane again after the turning and unload.Above-mentioned, effort not only time-consuming by overhead traveling crane clamping large-scale shaft workpiece; Simultaneously when operation crown block; To the handling workpiece be come in the clamp jaw of lathe chuck lightly and do accurate contraposition, and can not cause collsion damage chuck, otherwise; In case strike chuck, just probably the turning accuracy of lathe impacted.
Summary of the invention
The utility model technical problem to be solved is; When overcoming the large-scale shaft-like workpiece of prior art turning on lathe; To directly on chuck, make accurate contraposition clamping with the overhead traveling crane workpiece that plays, time-consuming, effort, bump chuck easily also during contraposition; Influence the shortcoming of lathe turning precision, a kind of lathe spindle class workpiece holder is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: on the bracing frame on can be placed in body of lathe bed guide rail, be supported with the arcs of recesses holder watt that can hold up the accurate subtend chuck hub of shaft-like workpiece line.
The utility model also has following technical characterictic:
The structure of support frame as described above is to be provided with two bases in the front and back along said bed ways, and the bottom surface of two bases is provided with the track that adapts, can be buckled in work front and back slip on the guide rail with the rail level of guide rail; Correspondence is provided with Tuo Wa respectively on two base tops, is connected and installed with the support arm that can regulate two holder watt height simultaneously on the base;
The installation of said support arm is on two bases before and after the said guide rail, to be positioned at centre position separately, along the parallel support of guide rail direction two pairs of down hinges is installed respectively; Be the lower end of the following support arm of two couples of herringbone setting relatively, be installed in respectively on the down hinge of said correspondence; Two couple below said two holders watt be just splay on support arm, its lower end is corresponding with the upper end of said down support arm respectively, and by along the setting of guide rail direction, be positioned at that the connecting axle and the outer connecting axle of both sides is through together inside and outside holding in the palm watt; Two holder watt connecting rods that are provided with along the guide rail direction, its two ends pass said hole of going up the support arm upper end respectively, support below the following recessed position that is installed in arcs of recesses holder watt, be positioned at the lateral aperture that its both sides are set up in parallel; The external end head of screw rod on the adjusting yoke is screwed in the middle penetrating screw of said outer connecting axle, the open-work in the other end of adjusting yoke passes in the middle of the connecting axle, and its termination is provided with handle;
Said down hinge is installed in the centre position on the base, is that the heart portion at former and later two bases is provided with groove, and the two ends of down hinge are supported on respectively on the medial surface that passes through groove two relative walls on the base.
During work, large-scale shaft-like workpiece is sling, be put on the cancave cambered surface that is positioned at said base top holder watt with overhead traveling crane; Shaft-like workpiece is held in the palm watt not to be held and can roll; And accurate subtend chuck hub line, the base above the chuck direction promotes guide rail can make workpiece get in the chuck jaw of lathe very like a cork; Tighten the chuck jaw clamping work pieces then, and carry out turning processing with the centre hole that the shaft-like workpiece spindle nose is stated in the residence, thimble pinnacle of installing on the tail stock; After accomplishing turning, with the order opposite workpiece is unloaded again with clamping workpiece.
The advantage and the good effect of the utility model are; Owing to can be earlier shaft-like workpiece be hung in the arcs of recesses holder watt of laying base top above the lathe guide rail with overhead traveling crane, and makes the center line of shaft-like workpiece subtend chuck, and then base is pushed in the chuck jaw; Rather than directly shaft-like workpiece is hung in the chuck jaw of lathe and do contraposition accurately with chuck with overhead traveling crane; The workpiece of handling does not contact chuck earlier, like this during people's operation crown block, just can be very like a cork workpiece be placed in the arcs of recesses holder watt; Can not damage chuck, just can the turning accuracy of lathe not impacted yet; Simultaneously, use above-mentioned bracing frame also to reduce the artificial potential safety hazard that leads man-machine cooperation in the work-handling process, also improved the efficiency of loading and unloading of workpiece.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to detail.
Among Fig. 1, on the bracing frame on can be placed in body of lathe bed guide rail 10, be supported with the arcs of recesses holder watts 2 that can hold up the accurate subtend chuck hub of shaft-like workpiece line.
