Description
Technical field
The present invention relates to car lathe process auxiliary equipment field, particularly relate to a kind of lathe workpiece alignment mechanism.
Background technology
The lathe of lathe to be main lathe tool to the workpiece rotated carry out turnery processing, it is indispensable pipeline, the equipment process equipment of petroleum chemical industry.
In the prior art, lathe many uses chuck realizes the fixing of parts to be processed.For making workpiece and lathe rotating shaft, there is good axiality, to obtain good machining accuracy, workpiece to be processed is generally wanted first to clamp in advance on chuck, then the rotary motion trace of workpiece is observed when the lathe spindle slow-speed of revolution is rotated, if there is larger swing at the radial direction workpiece of workpiece, need by again clamping or rap workpiece the axiality of the method adjustment workpiece such as operation and main shaft.During above operating cost, and the skill requirement of the size of beating point and percussion power to lathe operation personnel is high, is unfavorable for the turnery processing efficiency of lathe.
Summary of the invention
For above-mentioned existing lathe structure adjustment workpiece and lathe rotating shaft axiality time-consuming, and the problem high to the skill requirement of lathe operation personnel, the invention provides a kind of lathe workpiece alignment mechanism.
For solving the problem, a kind of lathe workpiece alignment mechanism provided by the invention solves problem by following technical essential: a kind of lathe workpiece alignment mechanism, comprise centering portion body, described centering portion body comprises mounting blocks, centering wheel bar and centering wheel, described mounting blocks is tabular, centering wheel bar is round bar shape, one end that one end and the centering of mounting blocks take turns bar is fixedly connected with, and the length direction of mounting blocks is parallel with the axis direction that centering takes turns bar, centering wheel is circular cone shape, centering wheel is provided with the through hole along its short transverse, described through hole and centering are taken turns bar and are become matched in clearance, and centering wheel and centering take turns the centerline collineation of bar.
The present invention is used for cylindrical work centering in bed.Concrete, the mounting blocks arranged is seated on the lathe tool mounting platform of knife rest, the fixing of the present invention and knife rest is realized by hold-down bolt on knife rest, workpiece pretension to be processed is on lathe chuck, after above operating procedure completes, brake lathe main shaft makes it slow circumvolve, by the cross slide of mobile lathe, knife rest is moved to chuck direction again, in the process of movement, centering roller contacts with surface of the work, interaction force between workpiece and centering roller realizes the adjustment of workpiece relative to lathe chuck inclination angle, automatically the axiality good with lathe spindle is adjusted at short notice to make workpiece.
Further technical scheme is:
Also comprise axle sleeve, outer limit screw cap and interior limit screw cap, described centering wheel bar is external thread rod, described axle sleeve is nested on centering wheel bar, and the internal diameter of axle sleeve and centering take turns the external diameter positive and negative deviation of bar in 0.2 millimeter, described centering wheel is nested on axle sleeve, and centering wheel becomes matched in clearance with axle sleeve, the internal diameter of centering wheel through hole is compared with the large 0.4-0.8 millimeter of the external diameter of axle sleeve, outer limit screw cap and interior limit screw cap are all taken turns bar with centering and are become threaded engagement, and centering wheel is between outer limit screw cap and interior limit screw cap.
In more than arranging, centering is taken turns bar and is set to external thread rod, be convenient to adjust the position of centering wheel on centering wheel bar, namely centering wheel is relative to the distance of knife rest, because the present invention only can utilize the round sides of workpiece to carry out workpiece automatic alignment, and minority workpiece complete clamping after its free end not there is desirable round sides, the setting that centering wheel is adjustable relative to centering wheel bar position, convenient operation personnel are according to the concrete shape of workpiece, best workpiece round sides is utilized to complete the automatic capturing of workpiece, and avoid because workpiece free end from knife rest too close to and cause workpiece and knife rest collision accident to occur, the length of preferred axle sleeve is slightly larger than the length of through hole, and axle sleeve is longer than through hole and is no more than 0.8 millimeter, takes turns and interior limit screw cap generation strong collision with workpiece, centering to prevent from take turns with centering during absorption surface at centering wheel, axle sleeve internal-and external diameter, centering wheel bar external diameter, centering take turns the setting of through hole internal diameter, make centering take turns the position conveniently moving on centering wheel bar, and only have centering wheel to rotate relative to axle sleeve when the present invention works, to prevent the external screw thread on boss failure centering wheel bar.
Because the lathe tool installed surface realized on knife rest is parallel relative to lathe spindle very easy, residing for the radial direction of taking turns for making centering and workpiece radial direction, plane is parallel to each other, also comprise the positive stop of tabular, described positive stop is fixedly connected on the side of mounting blocks, and positive stop is vertical relative to mounting blocks.Concrete, form a right angle angle between positive stop and mounting blocks, when the present invention is installed on knife rest, on described right angle angle and knife rest, the right angle good fit of lathe tool erector position, can ensure that mounting blocks is relative to lathe tool erector bit parallel.
For ease of processing of the present invention, described positive stop and mounting blocks as a whole.
For preventing the present invention from making premature breakdown of the present invention at centering wheel with impulsive force larger during absorption surface, the joint face of described centering wheel bar and mounting blocks smoothly transits.
The present invention has following beneficial effect:
1, after completing the present invention and the installation of workpiece on lathe, brake lathe main shaft makes it slow circumvolve, by the cross slide of mobile lathe, knife rest is moved to chuck direction again, in the process of movement, centering roller contacts with surface of the work, interaction force between workpiece and centering roller realizes the adjustment of workpiece relative to lathe chuck inclination angle, automatically adjusts to the axiality good with lathe spindle at short notice with making workpiece.Above operating process once completes, and axiality adjustment quality does not rely on the experience of producers, and axiality adjustment quality is high and efficiency is high.
2, centering wheel is set to circular cone shape, make the present invention to be applicable within the scope of certain diameter workpiece on lathe chuck with the adjustment of lathe spindle axiality, when workpiece is reducing workpiece, also realize centering wheel by the installation direction of adjustment centering wheel on centering wheel bar to contact with the optimum position of workpiece, make the present invention treat that turnery processing workpiece has good adaptive capacity to various.
3, install station because lathe saddle itself has multiple lathe tool, volume of the present invention is little, does not affect the installation of other lathe tools on lathe, normally cuts without impact lathe.
