Abstract
The invention relates to a device for processing reversed taper teeth of an internal spline of an automobile synchronizer tooth case, in particular to a numerical control gear rolling machine, which comprises a lathe bed and an upright post fixed on the lathe bed; an up-and-down slipway is connected with the upright post through a linear guide rail A; a hydraulic cylinder is arranged on the top of the upright post to control the slipway to move up and down; a cutter shaft internal taper sleeve is arranged in the up-and-down slipway; a workpiece end face pressing piece is connected with the up-and-down slipway through a linear guide rail B; a spindle is supported and arranged on the lathe bed through a bearing; a servomotor A drives the spindle and the spindle drives a cutter shaft to rotate; and an extruding slipway is arranged on the lathe bed through a linear guide rail C and is connected with a servomotor B through a ball screw. The M value variation of products processed by the numerical control gear rolling machine at a 2MM position is controlled within 0.03mm, the precision of the processed products is greatly improved, and the quality of the products is stabilized.
Description
Technical field
The present invention relates to automobile synchronizer tooth cover internal spline back taper tooth processing unit (plant), particularly a kind of numerical control gear tooth burnishing machine.
Background technology
Synchronizer gear sleeve internal spline back taper tooth processing request height, the M of 2MM place value variation requires in 0.06mm, the common gear tooth burnishing machine of former use adds man-hour, the M of 2MM place value variation is more than 0.1, former common gear tooth burnishing machine is to adopt the HYDRAULIC CONTROL SYSTEM radial feed, owing to be subjected to workpiece material hardness and ambient temperature effect, the radial feed positioning accuracy is poor, can't guarantee to process qualified product.
Summary of the invention
The object of the invention provides the high numerical control gear tooth burnishing machine of a kind of machining accuracy.
Technical solution of the present invention: a kind of numerical control gear tooth burnishing machine, comprise lathe bed and be fixed in the lathe bed upper pillar stand, slide unit is connected with column by the line slideway first up and down, slide unit moved up and down about hydraulic cylinder was installed in the control of column top, up and down in the slide unit cutter shaft inner conical drogue is being installed, the workpiece end face compressing member is connected with slide unit up and down by line slideway second; Main shaft is installed on the lathe bed by bearings, servomotor first drive shaft, and main shaft drives the cutter shaft rotation; The extruding slide unit is installed on the lathe bed by line slideway third, and it connects servomotor second by ball-screw.
Extruding slide unit radial feed accuracy is at 0.008mm.
The present invention is easy and simple to handle, has alleviated operator's labour intensity greatly, has improved production efficiency, generally speaking, can finish the processing of single-piece synchronizer gear sleeve internal spline back taper tooth in 40 seconds; Product processed has been controlled in the 0.03mm in the M of 2MM place value variation, has improved the precision of converted products greatly, has stablized product quality.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is Fig. 1 left view.
1 servomotor first among the figure, 2 main shafts, 3 tooth covers (workpiece), 4 cutter shafts, 5 workpiece end face compressing members, 6 cutter shaft inner conical drogues, slide unit about in the of 7,8 hydraulic cylinders, 9 extruding slide units, 10 ball-screws, 11 servomotor second, 12 columns, 13 line slideway first, 14 line slideway second, 15 line slideways, the third, 16 lathe bed.
The specific embodiment
The present invention is made up of lathe bed, column, extruding slide unit, workpiece end face compressing member, Hydraulic Station, control system etc., and main shaft adopts the SERVO CONTROL frequency control, and the vehicle positioning stop function is arranged, and Hydraulic Station places the lathe bed rear portion, easy access and maintenance.
Lathe bed is welded into by steel plate, and is steadily reliable for guaranteeing moving component, and the main components casting forms.Slide unit is connected with column by the line slideway first up and down, slide unit moved about hydraulic cylinder was installed in the control of column top, the workpiece end face compressing member is connected with slide unit up and down by line slideway second, the workpiece end face compressing member can about adjust the position, make the workpiece end face compressing member guarantee all the time with workpiece at same center; Slide unit is connected guaranteed that the end face compressing member moves up and down steadily reliable with hydraulic system up and down, for preventing the cutter shaft distortion, in the slide unit cutter shaft inner conical drogue is being installed up and down, there is being radial support the cutter shaft upper end, strengthening the cutter shaft rigidity to greatest extent and prolonged service life; Extruding slide unit servomotor second connects the extruding slide unit by ball-screw, and line slideway third has guaranteed the precision of extruding slide unit motion, and the extruding slide unit is connected with lathe bed by line slideway third, and extruding slide unit radial feed can accurately be positioned at 0.008mm during extruding; The servomotor first connects main shaft, and main shaft is connected with lathe bed by bearings, guarantees the main axis rotation precision.
Manual material loading of lathe and discharging, workpiece processing is finished automatically; Control system has sets the function that extruding slide unit radial feed displacement and spindle speed, the number of turns are complementary, and satisfies the processes requirement.The machine operation person can set parameters such as the speed of mainshaft, the forward and backward number of turns and the displacement of extruding slide unit radial feed; Generally speaking, finish the processing of single-piece synchronizer gear sleeve internal spline back taper tooth in can be in 40 seconds, product processed has been controlled in the 0.03mm in the M of 2MM place value variation, has improved the precision of converted products greatly.
During work, at first the workpiece end face compressing member moves downward the workpiece pressing end face, and the extruding slide unit is fast-forward to the initial position of program setting; Main shaft starts by setting the rotating speed rotation, when main shaft starts, the extruding slide unit is fed into the operating position of setting simultaneously, main shaft counter-rotating after just forwarding the setting number of turns to, after rotating to the setting number of turns, stop, the extruding slide unit returns to original position, and the workpiece end face compressing member upwards returns to original position, takes out workpiece and machines.
