Abstract
The utility model relates to a metal bar centering guide apparatus which achieves the integrated multiple functions of automatic centering guide and clamping to aligned metal bars, and is characterized in that a flange sleeve and a holding chuck are arranged on a support, the flange sleeve is located by the center of the holding chuck, an inner guide bushing is mounted in the flange sleeve, a bearing and a shaft are arranged on a gripping jaw of the holding chuck, and a sheath is arranged on the periphery of the holding chuck. The utility model has good concentric stability, the contact surface of the metal bar and a roller has no scraping phenomena, and meanwhile the resistance force of the metal bar is reduced in the operating process, the dust prevention measures are adopted, dirty substances and dust are not allowed to enter, the cleaning is not needed in any environment, and the utilization is flexible and reliable.
Description
Technical field
The utility model relates to a kind of device that uses in the process of metallic rod, relate in particular to a kind of metallic rod after the alignment has been realized the self-centering guiding, clamped the multi-functional metal rod centering guiding device of one that is.
Background technology
At present, known metallic rod to any material all must guiding and centering in process, conventional centering pilot method is according to different metallic rod materials, selects different centering pilot materials for use, by the processing technology form, adopt different structures, generally use guide pin bushing, mould or wheeled.Basic structure is that the former is made up of the guide pin bushing support, the roller set that the latter is made up of the monocycly two-wheel.These two kinds of citation forms all are to change corresponding guide pin bushing or roller pass size according to different metallic rod outside dimensions.Wherein the problem of guide pin bushing existence is, metallic rod is in the process of operation, and the metallic rod surface contacts with the guide pin bushing endoporus and produces the static friction wearing and tearing comparatively fast, loses positioning accuracy very soon, or wound metallic rod surface, and the centering of two kinds of forms does not possess versatility with guiding.
The utility model content
The utility model is in order to solve the problem that exists in the above-mentioned conventional art; by a large amount of tests and constantly exploration; the metal rod centering guiding device of a kind of centering pilot precision height, highly versatile is provided; lose the problem on positioning accuracy or sliding injury metallic rod surface when having solved centering pilot metallic rod in the prior art easily; the utility model can carry out static state adjustment according to different metal bar outside dimension simultaneously; also can be in the metallic rod running; the self-centering precision is adjusted in folding and unfolding, need not to shut down to carry out.
To achieve these goals, the technical solution of the utility model is as follows:
Flange cover and chuck are set on the support, and the flange cover is by the chuck centralized positioning; Fairlead in install the inside of flange cover; The jaw of chuck is provided with bearing and axle, and the periphery of chuck is provided with sheath.
Described jaw is three, is separately installed with on the jaw to have certain distance and two bearings on same central line.
Described support and sheath seam axially between be provided with back-up ring, back-up ring and sheath are for movingly.
The adjustment hole of described chuck is corresponding with the hole in the sheath, and sheath is by adjusting the corresponding chuck of packing into of slot to make way that the place, hole offers with three of chucks.
The utility model also comprises the bolt of fastening metal bar.
The utility model has the advantages of as follows:
The utility model has taked the centering of bikini straight line to have good entad stability, the surface that metallic rod contacts with roller does not have the scuffing phenomenon, reduced the resistance of metallic rod in running simultaneously, and taked dust prevention, no foul and dust enter, working in any environment all need not to clear up, and uses flexibility and reliability.
Owing to adopted technique scheme, the utility model to overcome weak point in common metal bar, the centering pilot.The utility model is a special-purpose member in the corollary equipment.Be exclusively used in the centering pilot of metallic rod, use the utility model to coiling scrubbing of round aluminium rod surface, dish circle aluminium bar is taken turns through alignment, enter the utility model device after the alignment, the aluminium bar is scrubbed in the process in operation, does not have any porpoising phenomenon, high life, roller and aluminium bar contact zones action-oriented wheel rolling-operation does not produce any guiding undesirable element in the jaw.Compare the stability height with other guidance method, easy to use flexible.
Principle of the present utility model is as follows:
Introduce smoothly in the utility model clamping mechanism for the assurance metallic rod, in the flange cover, interior guide pin bushing is housed, and fixes by holding screw, when metallic rod enters the operation of this mechanism, between metallic rod and the inner catheter certain interval is arranged, do not produce friction, only play the introducing effect, interior guide pin bushing is the pre-guide of metallic rod.The centering of metallic rod, guiding and clamping are realized by chuck; When needs adjustment clamping guiding was spent, the hole that rotates on the outer back-up ring was corresponding with shield bore.By the chuck wrench adjustment, rotate any one angle of outer back-up ring when overlapping with sheath angle hole, sheath has promptly formed a closed cavity, thereby has prevented entering of foul, dust; Introduce metallic rod, after the adjustment metallic rod needs direct bearing, metallic rod is fastening by bolt.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further specified.
