Description
Technical field
The present invention relates to a kind of roll extrusion assemble mechanism, belong to machinery manufacturing technology field.
Background technology
Some product structures are that part combines with the plug-in type of part, and have certain adhesion (properties of product requirement) through mechanical presses.The thin-plate member insertion and the press fit (being generally the parts of plastic metal material) of thin-plate member with the band groove of band chimb are typically arranged, and the morpheme size tolerance requirements of assembly is strict.Its assembly technology universal method is at present: each parts manufacturing is finished, insert assembling, push the combination assembling with roller then.
This roll extrusion work is the special process process, does not have suitable fixture and unique process program to be difficult to realize.Yielding in the multiple clamping of thin-plate member in different operations (machined, assembling etc.), form and position tolerances such as the linearity of parts, flatness are difficult for guaranteeing; Benchmark secondary centering during assembling, final assembly parts size form and position tolerance also are difficult to guarantee; The important technologies such as adhesion of parts require to be difficult for realizing and guaranteeing in the assembly; Usually rolling wheel self precision and roll extrusion kinematic accuracy are not enough, cause some assembly technical requirements (extruding adhesion) of product not reach drawing requirement.
Summary of the invention
The object of the present invention is to provide and a kind ofly can realize roll extrusion assembling, improve assembled precision, the compact a kind of roll extrusion assemble mechanism between the workpiece.
Technical solution:
A kind of roll extrusion assemble mechanism comprises: numerically controlled machine is installed with symmetrically arranged clamping supporter on numerically controlled machine; Clamp on the supporter inwall and be respectively equipped with workpiece; It is fastening by clip to clamp supporter and workpiece top, and symmetry has rolling groove on the workpiece opposite face, and second workpiece is installed in the rolling groove of workpiece relative inner; Workpiece relative inner bottom is established first respectively and is clamped the voussoir and the second clamping voussoir, and second clamps voussoir places first to clamp the voussoir middle part.
Said first clamps voussoir and second clamps voussoir inclined-plane crimping.
Said clamping supporter is provided with reinforcement.
Component processing of the present invention and assembled concentrate on the equipment carries out, and after the parts cut, does not does not load and unload, and carries out the roll extrusion assembling continuously, makes component processing and assembly manipulation unify benchmark; Roll extrusion control accurately; Final load module form and position tolerance meets drawing, and technical indicators such as adhesion, gap meet the demands, and the uniformity of assembly is good.

The specific embodiment
Embodiment 1:
A kind of roll extrusion assemble mechanism; Comprise: numerically controlled machine 1, on numerically controlled machine, be installed with symmetrically arranged clamping supporter 6, clamp supporter 6 and be provided with reinforcement; Be respectively equipped with workpiece 4 on the inwall of clamping supporter 6; It is fastening by clip 5 with workpiece 4 tops to clamp supporter 6, and symmetry has rolling groove on workpiece 4 opposite faces, and second workpiece 3 is installed in the rolling groove; Workpiece 4 relative inner bottom establishes the first clamping voussoir 8 respectively and the second clamping voussoir, 7, the second clamping voussoirs 7 place first to clamp voussoir 8 middle parts.
The roll extrusion installation step is following:
1) be installed with symmetrically arranged clamping supporter 6 on the numerically controlled machine 1, the spacing dimension and the depth of parallelism that clamp supporter 6 opposite faces will be adjusted in advance; Clamp on supporter 6 inwalls and be respectively equipped with workpiece 4; It is fastening by clip with workpiece 4 tops to clamp supporter 6; The two ends of bottom are placed with the first clamping voussoir 8, the second respectively and clamp the middle part that voussoirs 7 place first clamping 8, and the second clamping voussoir, 7 inclined-planes butt up against first and clamp voussoir 8 inclined-planes; Place first of the second clamping voussoir, 7 two ends to clamp on the voussoir 8 and be respectively equipped with bolt, and the inclined-plane crimping that in fastening bolt, second clamping voussoir 7 inclined-planes and first is clamped voussoir 8 is adjacent to; So just workpiece 4 is fixed in the clamping supporter 6 securely, the precision that the opposite face spacing dimension precision of workpiece 4 and the depth of parallelism lean on above-mentioned accurate adjustment to clamp supporter 6 opposite faces guarantees.
2) utilize Digit Control Machine Tool, through the metal cutting campaign of metal saw cutter, process symmetrically arranged rolling groove on workpiece 4 opposite faces, the size of the groove on the workpiece 4 and mutual alignment size are able to good assurance, and dimensional uniformity is good.
3) do not unload workpiece 4, second workpiece, 3 two ends are inserted respectively in the rolling groove of workpiece 4.In in second workpiece 3 inserts workpiece 4 grooves, hand-held second workpiece 3 is straight, and it is slow that action is wanted, and prevent the friction of second workpiece 3 and workpiece 4 grooves, has drawn the metal fillings, burr of plastic metal material etc.In whole insertion process, run into difficult slightly place of inserting, be lubricated with absolute ethyl alcohol.
4) with second workpiece 3 respectively with workpiece 4 on roll extrusion cell wall riveted joint.Promptly rap on the roll extrusion cell wall on workpiece 4 two ends with pointed Metallic rod, second workpiece 3 has been lived in riveting like this, prevent second workpiece 3 in follow-up roll extrusion process along roll extrusion direction of advance play.
5) rolling wheel 2 is placed in the main shaft of numerical control machine tool 1;
6) utilize Digit Control Machine Tool, through the accurate motion of rolling wheel 2, the joint to the workpiece 4 and second workpiece 3 carries out roll extrusion respectively.In motion process; Under the situation of given machine spindle speed not; Rolling wheel 2 moves according to the numerical control program of finishing rolling pressing on the chimb of the rolling groove of workpiece 4, and rolling wheel 2 rotates with the mobile feeding of rolling wheel and together with machine tool chief axis 1 owing to roll extrusion frictional force; Rolling wheel 2 is the pressing coordinate on workpiece 4 chimbs, is through early stage, repeatedly the test of roll bonded power was selected.
A kind of rolling wheel 2 that is used for the roll extrusion assembly method comprises the cutter handle of a knife, is provided with wheel shaft in the cutter handle of a knife, and wheel shaft is provided with pinch roller, and said cutter handle of a knife, wheel shaft and pinch roller are one, and the working face of pinch roller is the conical surface.
Through above-mentioned steps, the roll bonded of the workpiece 4 and second workpiece 3 is achieved, and form and position tolerance such as dimensional accuracy of assembly, the depth of parallelism is guaranteed, and each size of components uniformity of batch assembling is good.
Rolling wheel of the present invention also can be cutter handle of a knife and wheel shaft, and to be designed to one or wheel shaft and pinch roller be one.
