Description
technical field
The present invention relates to a kind of 8-shaped side plate cylindrical turning fixture being exclusively used in 8-shaped side plate cylindrical turning processing.
Background technology
8-shaped side plate is installed in the oil pumping chamber of gear oil pump, and during operation of oil pump and the end face movable contact of pump oilgear, 8-shaped side plate is accurately to locate in oil pumping chamber and to seal, and needs its outline left and right semicircle to have high roundness of external circle and fineness.And Excircle machining to be carried out to the left and right semicircle of 8-shaped side plate, the biggest problem of current existence is: 1. traditional diamond-making technique and defect: use conventional brace clamping on lathe, two circle centre-to-centre spacing precision can be ensured, but the cylindrical of left and right semicircle can not be processed, with fixture at plain-milling machine copying cylindrical, cylindrical fineness and circularity are difficult to reach drawing requirement, and production efficiency is not high yet; 2., by CNC milling machine or Cutter Body Processing with Machining Center: centre-to-centre spacing precision can reach drawing requirement, circularity and surface roughness are difficult to reach drawing requirement (high accuracy processing cost is very high), and production efficiency is low.Certainly also linear cutter can be adopted, but efficiency is lower, more cannot meet production in enormous quantities.
Summary of the invention
In view of current known technology Problems existing, the technical problem to be solved in the present invention is to provide a kind of cylindrical turning processing being exclusively used in 8-shaped side plate, structure is simple, make the roundness of external circle of workpiece and roughness easily can reach drawing requirement, and the 8-shaped side plate cylindrical turning fixture that production efficiency is high.
For solving the problems of the technologies described above, the present invention takes following technical scheme:
8-shaped side plate cylindrical turning fixture, comprise and be fixed on clamping apparatus disk on lathe spindle and replace lathe saddle to carry out the slide unit installed, it is characterized in that: the center of described clamping apparatus disk is provided with the location of positioning core axle for the centre bore of 8-shaped side plate, the axis of positioning core axle and the spinning central coaxial of described clamping apparatus disk, the end face neighboring of described clamping apparatus disk is provided with the concavo-convex dish of end face, and the height point of the concavo-convex dish of end face and the difference in height of low spot are greater than the thickness of 8-shaped side plate; Described slide unit comprises slide plate, slide, lathe tool mounting rod, cam follower and spring, slide is fixed on lathe middle carriage, slide plate is arranged along the axial direction slide anteroposterior of lathe spindle on slide, described lathe tool mounting rod is with the front end stretching in slide plate outside cam follower and be fixedly connected with slide plate, billmpse tool installed by the rod end of lathe tool mounting rod, roller installed by the rod end of cam follower, and the rolling surface of roller is arranged facing to the curved surface of the concavo-convex dish of end face, and the rear end that slide plate is located at by described spring pushes slide plate; When carrying out turnery processing to the cylindrical of 8-shaped side plate, the concavo-convex dish of end face and clamping apparatus disk rotate with lathe spindle, roller by rolling on the concavo-convex dish of end face drive slide plate and billmpse tool do on the axial direction of lathe spindle back and forth enter tool backlash movement.
After adopting technique scheme, engine lathe can realize carry out turnery processing to the cylindrical of 8-shaped side plate (clamping apparatus disk is fixed on lathe spindle, knife rest on lathe middle carriage is pulled down and changes slide unit), operation principle of the present invention is: first utilize the left side centre bore of 8-shaped side plate to carry out Internal hole positioning (left side centre bore is set on positioning core axle) and then clamp, then by the movement of lathe saddle make slide move to position that roller and the concavo-convex dish of end face carry out contacting and spring has certain decrement, adjust the position of billmpse tool simultaneously; When carrying out turnery processing to the cylindrical of 8-shaped side plate, lathe spindle drives clamping apparatus disk, the concavo-convex dish of end face and workpiece synchronous axial system, roller makes play back and forth by the rolling drive slide plate on the concavo-convex dish of end face and billmpse tool on the axial direction of lathe spindle, thus produce axial feed and tool backlash movement, the position of turning is needed at left half cylindrical of side plate, the low point cantact of roller and the concavo-convex dish of end face, lathe tool advance turning workpiece excircle; The position (i.e. the connecting part of half cylindrical and adjacent regions about 8-shaped side plate) of turning is not needed at left half cylindrical of side plate, the high point cantact of roller and the concavo-convex dish of end face, lathe tool retreats, lathe tool passes through above the end face of 8-shaped side plate, lathe tool can not encounter side plate, above-mentioned enters tool backlash movement and coordinates the axial feed of lathe saddle and the radial feed of lathe middle carriage, and a left side half cylindrical of 8-shaped side plate just can be made by turning to be reached the processing dimension of its cylindrical; After left half cylindrical turning of side plate machines, unclamp workpiece, carry out Internal hole positioning by utilizing the right centre bore of 8-shaped pad after workpiece turning 180 degree then to clamp, just can carry out turnery processing to right half cylindrical of side plate subsequently, turning process is the same with the turnery processing of left half cylindrical.In above-mentioned whole Tutrning Process, the circularity of excircle of workpiece is ensured by the precision of beating of lathe spindle completely, the roughness of excircle of workpiece is then controlled by the feed of lathe saddle and the rotary speed of lathe spindle, so the roundness of external circle of workpiece and roughness can be made easily can to reach drawing requirement.In addition, because workpiece can carry out the turnery processing of traditional approach on engine lathe, highly efficient in productivity.
