Description

Double end numerical control special purpose lathe
Technical field
The utility model relates to double-ended boring machine and lathe, and particularly a kind ofly be mainly used in processing and be difficult for the secondary positioning and clamping, and the double end numerical control special purpose lathe of the axiality disk cover parts of having relatively high expectations.Belong to the lathe technical field.
Background technology
Existing lathe generally has only a cutter head, and is positioned at the outside portion of rotational workpieces, and when running into the higher disk cover parts of hole, two requirement on machining accuracy, its precision and working (machining) efficiency will obviously descend.Existing double end numerical control borer is mostly by left and right carriage saddle, left and right saddle, left and right vertical ball screw assembly,, left and right servo longitudinal motor, left and right rotating knife (boring) tool, and be fixed on fixation workpiece seat between the left and right carriage saddle and numerical control device is formed, can be used for processing the disk cover parts that is difficult for the secondary positioning and clamping.But be difficult for the secondary positioning and clamping for processing, and the disk cover parts that axiality is had relatively high expectations, as automobile brake wheel hub, because two cutter (boring) tool of double end numerical control borer is in rotation status, workpiece in the middle of placing remains static, thereby, when machine tool component has wearing and tearing, must cause the shaft center line of cutter (boring) tool and the axial line of workpiece deviation to occur, directly influence the axiality of workpiece.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of at above-mentioned weak point and is applicable to that processing is difficult for the secondary positioning and clamping, and the double end numerical control special purpose lathe of the axiality disk cover parts of having relatively high expectations.
Technical solution of the present utility model is: a kind of double end numerical control special purpose lathe, comprise left and right carriage saddle, left and right saddle, left and right vertical ball screw assembly,, left and right servo longitudinal motor and numerical control device, it is characterized in that: between left and right carriage saddle, be provided with the spindle drum of fixedlying connected, be provided with main shaft, transmission case and variable-frequency motor in this spindle drum with it.Be provided with horizontal left and right middle carriage on left and right saddle, this left and right middle carriage is provided with supporting left and right lead screw pair and the left and right horizontal servomotor of laterally rolling.On left and right middle carriage, be respectively equipped with electric driving tool post.
The utility model is owing to be provided with spindle drum between left and right carriage saddle, and in spindle drum, be provided with main shaft, transmission case and variable-frequency motor, thereby, when the disk cover parts that will be difficult for the secondary positioning and clamping such as automobile brake wheel hub clamping workpiece after on the main shaft, just this workpiece can be with main axis rotation.Simultaneously, by the position of numerical control device adjustment and fixing left and right electric driving tool post, making the cutter blade is workpiece radius to be processed to the distance of spindle axis line; Promote left and right saddle and move, finish processing workpiece to the center.Obviously, said process can guarantee the axiality unanimity of workpiece two ends processing fully.Even the machine tool component wearing and tearing occur, also just the rotation centerline and the cutter height of workpiece produce some micro-deviations, and this deviation is easy to revise by adjusting, and does not influence the axiality of workpiece.The utility model is mainly used in processing and is difficult for the secondary positioning and clamping, and the axiality disk cover parts of having relatively high expectations.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the plan structure schematic diagram of Fig. 1; Fig. 3 is main shaft and workpiece clamping schematic diagram; Fig. 4 is the spindle drive schematic diagram.
The specific embodiment
As shown in Figures 1 to 4.Left and right carriage saddle 2,13 symmetries are fixed on spindle drum 19 two ends.Left and right carriage saddle 2,13 is provided with regulator cubicle door 3,12.Left and right saddle 4,11 is separately positioned on the left and right carriage saddle 2,13, and respectively with left and right vertical ball screw assembly, 15,23, left and right servo longitudinal motor 1,14 matches.About vertically ball screw assembly, 15,23 inner ends be in respectively on the leading screw seat 18,20.Left and right middle carriage 5,10 is separately positioned on the left and right saddle 4,11, matches with left and right horizontal ball wire bar pair 16,22 and left and right horizontal servomotor 17,21 respectively.Left and right electric driving tool post 6,9 is separately positioned on the left and right middle carriage 5,10.Main shaft 24 is positioned at spindle drum 19 tops, and transmission case 8 is positioned at spindle drum 19 middle parts, and variable-frequency motor 27 is positioned at spindle drum 19 bottoms, and main shaft 24, mainshaft gear 28, carrier gear 29, motor gear 30 and variable-frequency motor 27 match, and control by numerical control device.Numerical control device can adopt conventional numerical control device.Numerical control operation panel case 7 is used to finish the operation of workpiece process.Numerical control device can conveniently be controlled the location of left and right electric driving tool post 6,9 and move to workpiece coaxially, finishes the coaxial processing to the workpiece two ends.
Workpiece 26 is an automotive hub, be difficult to the secondary positioning and clamping, be fixed on the main shaft 24 by axial anchor clamps and locating ring 25, and there is the strict requirement of beating seam, end face many places to workpiece 26 two ends, and adopt the utility model to process, can on same axial line, finish the seam at two ends, the processing of end face simultaneously, and overcome the phenomenon of the malalignment that double end thorax bed produces because of lathe wearing and tearing fully.
