The driving motor is installed at the back of the sliding pillow of the knife rest, and symmetrical oil cylinders are installed on the knife rest body on two sides of the sliding pillow. The knife rest structure adopts a servo motor to drive the ball screw to rotate and feed, feeding quantity is easy to control, cutting force can be better balanced, and processing accuracy is guaranteed.
Description
Technical field
The present invention relates to a kind of cutter frame structure, especially a kind of structure that is applicable to the vertical lathe numerically-controlled slide belongs to the machinery industry field.
Background technology
In the vertical lathe industry, the precision of tool feeding structure has a direct impact the processing work precision, and the feed accuracy of feeding structure is low, and Workpiece Machining Accuracy is corresponding reduction also, therefore to the design of cutter feeding structure, to improving Workpiece Machining Accuracy very large meaning is arranged.In vertical lathe processing, the tool feeding structure that generally adopts is that ordinary three-phase synchronous drives screw mandrel rotation feeding, there is the low problem of feed accuracy in this kind feeding structure, therefore in the processing work process, Workpiece Machining Accuracy is low, adopt monolateral balancing cylinder balanced cutting power, equilibrant force is unstable, also can affect Workpiece Machining Accuracy.
Summary of the invention
Purpose of the present invention is being improved original technology, a kind of numerically-controlled slide feeding structure simple in structure, ingenious, rational is provided, this structure adopts the driven by servomotor ball screw to rotate feeding, the amount of feeding is easy to control, and the more original feeding structure precision of feed accuracy is high, balancing cylinder adopts symmetrical structure, better balance the cutting force of process, the raising of workpiece crudy is greatly improved.
According to technical scheme provided by the invention: a kind of vertical lathe cutter frame structure comprises pressing plate, wedge, drive motors, decelerator, shaft coupling, speed reducer base, bearing assembly, ball screw, tool-post structure, deep groove ball bearing, cover plate, oil cylinder gripper shoe, cylinder rod and cylinder body; Described wedge is by the first bolt, the second bolt and contiguous block are fixed on the pressing plate, described drive motors is connected with decelerator, decelerator is fixed on the speed reducer base, speed reducer base is fixed on the tool-post structure, shaft coupling connects ball screw and decelerator, described bearing assembly is installed in the tool-post structure, screw mandrel is by the bearing assembly internal diameter, the upper end is by spacer the first nut check, and described ball screw screws in hangs the angle nut, hangs the angle nut and is bolted on the ram by the 3rd, described deep groove ball bearing is installed on the tool-post structure, the screw mandrel axle journal is by the deep groove ball bearing endoporus, and described cover plate is bolted on the tool-post structure by the 4th, deep groove ball bearing outer ring, location, described oil cylinder gripper shoe is installed in ram top, cylinder rod is by the adjusting pad adjustment, and on the oil cylinder gripper shoe, cylinder body is fixed on the tool-post structure with the second nut check.
As a further improvement on the present invention, described drive motors is installed in knife rest ram back, and symmetrical oil cylinder is installed on the tool-post structure of ram both sides.
As a further improvement on the present invention, described drive motors is installed in the ram back.
The present invention compared with prior art, advantage is: the present invention adopts the driven by servomotor ball screw to rotate feeding and numerical control control, and the amount of feeding is easy to control, at ram both sides tool-post structure symmetrical oil cylinder is installed, in process, can better balanced cutting power, guarantee machining accuracy.
