Background technology
Common endoporus grinding machine can be realized the taper hole of grinding straight hole and little tapering (tapering is in 12 °).Its structure is made up of headstock assembly, lathe bed, guide rail, bistrique assembly, deflection mechanism, transmission device and control system.Because the restriction of lathe bed structure, guide rail width and deflection mechanism stroke, this class grinding machine can not realize the grinding to ISO system taper hole (be the 7:24 taper hole, its tapering is 16.3 °), more can not finish to big specification as
The grinding of the ISOBT60 taper hole on the workpiece of length more than 4000.The endoporus grinding machine of manufacturer production such as domestic major vendor Shanghai Machine Tool Plant, Wuxi lathe Co., Ltd, Beijing No.2 Machine Tools Factory all is in this state, and the comply with one's wishes endoporus grinding machine of productions such as big profit, Germany, Czech of advanced in the world lathe production country can not solve the grinding that the ISO on the large-size workpiece makes taper hole.Along with China " ten. the First Five-Year Plan " plan revitalizes the manufacturing enforcement of domestic equipment, the main shaft of numerical control machine tool unit almost all designs and uses ISO system taper hole structure, existing endoporus (or omnipotent) grinding machine can not realize that this difficulty becomes the technical bottleneck of main axle unit functional part exploitation to the processing of ISO system taper hole.
Summary of the invention
The object of the present invention is to provide a kind of universal boring grinding machine, the grinding that this universal boring grinding machine can be realized the ISO system taper hole on the large-size workpiece also can realize the grinding of straight hole, mohs tapered bore, metric system taper hole, special-purpose taper hole simultaneously.
For achieving the above object, technical program of the present invention lies in: comprise lathe bed, bistrique assembly, transmission device, control system, centre frame is arranged on the upper table surface, centre frame one end is corresponding with the bistrique assembly, one end is corresponding with headstock assembly, and upper table surface one end has the headstock assembly of upper table surface moving linearly relatively, and upper table surface has bearing pin to be connected with bridge plate, upper table surface can rotate around bearing pin, and upper table surface is equipped with the deflection mechanism that can regulate its angle.
Following table, bridge plate are housed on the said lathe bed, and upper table surface is installed on following table and the bridge plate, and the following table size shape is greater than ISO system taper hole tapering.
Said its base of deflection mechanism of regulating the upper table surface angle is loaded on the side of following table and connects with upper table surface by feed screw nut's transmission, drives screw mandrel, and nut drives upper table surface and rotates the adjusting that realizes tapering around bearing pin.
An end of screw mandrel described in said feed screw nut's transmission is for realizing the semiglobe of universal property.
Said bearing pin and upper table surface matched in clearance, bearing pin and bridge plate interference fit, a pivot that eccentric position is a bearing pin of bridge plate.
The headstock assembly of said upper table surface moving linearly relatively is loaded on the backing plate assembly, and the transmission of gear in the backing plate assembly and upper table surface upper rack realizes the rectilinear motion of headstock assembly with the backing plate assembly.
Its operation principle is: after work piece hoisting finishes, start lathe, drive deflection mechanism and bistrique assembly, adjust tapering, regulate annexes such as centre frame, the bus benchmark of calibration workpiece, every adjustment is suitable, starts headstock assembly, the workpiece rotation, start the bistrique assembly, the grinding tool feeding realizes the grinding to the workpiece taper hole.
After adopting structure of the present invention, following table is by make its size shape of taper hole taper design greater than ISO during design, structural design in the deflection mechanism realizes universal property, pivot at upper table surface adopts an eccentric design, and these combinations that improve design have realized the accurate grinding processing of ISO system taper hole on the large-size workpiece.The present invention can realize 45 ° of deflections (22.5 ° of cone angles) with interior tapering at any angle, and the processing work length range is 1500～5000, diameter
Reaching machining accuracy is: awl orifice end circularity 0.004, and check rod stretches out 300 place's circles and beats 0.008～0.01, and surface roughness Ra 0.4 adheres to specification fully, also can realize the grinding of straight hole, mohs tapered bore, metric system taper hole, special-purpose taper hole simultaneously.
