Abstract
The utility model relates to a ball screw nut opening-closing mechanism which belongs to the component for transferring the power and the motion of the machinery. A nut whose excircle position is symmetrically opened with slots and the ball screw are together arranged in a nut seat which is opened with slots upward and downward. A fastener which can inserted into the boss of the outer circular slot of the screw nut is arranged on the position which is opened with slots upward and downward of the nut seat. The fastener is used for clamping or disengaging the ball screw nut. The problems that a general machine tool which is refitted to be controlled by a microcomputer can not still have the functions of hand operating and maneuver of the original machine tool can be solved. Thus the utilization rate of machine tools can be improved. The utility model has the advantages of convenient operation, low cost and simple structure.
Description
A kind of ball-screw nut open-and-close mechanism, belong to mechanically a kind of transferring power and the parts of motion.
It all is can only drive the slip crate system with leading screw drive nut mechanism to realize automatic processing that the ball-screw that uses is gone up in the simple nc machine repacking of generally carrying out in recent years, and the transmission system of former lathe partly is removed, and gearing does not recur.Thereby the machine tool original function has been subjected to certain restriction, makes a general lathe become single-minded automatic processing machine tool.This part to producing in enormous quantities has improved production efficiency.But the product little or various in style to manufacturing batch, because after the machine tool repacking, original mechanism partly is removed can't be according to the function operation of former lathe, thereby the lathe after the repacking just can not be participated in production, reduced the utilization rate of lathe, also be subjected to influence because the influence of this factor is carried out the repacking work of machine tool.
The purpose of this utility model is that microelectric technique is transformed that function behind the machine tool evolved by single-minded digital control processing type is numerical control and former transmission system function compatible type, make the lathe after the repacking both can process the part of some production in enormous quantities automatically as Digit Control Machine Tool, can throw off control of microcomputer again, power drive by former lathe, bring into play its original function, processing small batch, the part in addition of different cultivars.
Solution of the present utility model be at the place, outer garden of feed screw nut along the several trough of opening of contour direction symmetry, feed screw nut is together packed into movingly together with ball-screw is installed in the nut seat on the slip crate then.Nut seat have groove up and down.One end of a pair of clip that has a boss by pin be installed in ditch in the nut seat poor in, clip can rotate around pin.Be installed in the bolt on the nut seat, compression spring, nut clamp the other end of clip, and the boss close-fitting of clip is gone in the groove of feed screw nut.When stepper motor started, leading screw rotated, and makes slip crate do lengthwise movement on lathe by feed screw nut, clip, nut seat, can finish digital control processing by certain program.If need of work recovers former lathe function, only need nut (1) is unscrewed, because the effect of compression spring (6), throwing off the groove in the garden outside feed screw nut of the boss on the clip is that clip is in opening, lathe can drive slip crate by feed rod, rack-and-pinion according to motive power, transmission system and do lengthwise movement along lathe bed, realizes manual, motor-driven processing.At this moment, because the moving of slip crate, the feed screw nut empty rotation that only on leading screw, accompanies.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is operating position figure of the present utility model.
Fig. 2 is a profile of the present utility model.
Among the figure: 1, clamp nut; 2, spring washer; 3, clip; 4, pin.5, bolt; 6, compression spring; 7, nut seat; 8, feed screw nut; 9, ball-screw; 10, stepper motor; 11, slip crate;
Shown in accompanying drawing 1,2, in the feed screw nut (8) of having opened two grooves of place, outer garden symmetry and ball-screw (9) nut seat (7) of slotting up and down of packing into movingly.Nut seat (7) is by being bolted to slip crate (11) side.Two clips (3) that have boss are installed in the trough of nut seat (7) symmetrically by pin (4).Clip (3) one ends can rotate around pin (4), and the other end will be gone up lower catch hoop and is associated in together by bolt (5), compression spring (6), spring washer (2), nut (1).The boss of clip (3) is inserted in the outer garden groove of feed screw nut (8), and when fastening nut (1), the boss close-fitting of clip (3) is gone in the outer garden groove of feed screw nut (8).When stepper motor (10) startup, ball-screw (9) begins to rotate, by feed screw nut (8), and clip (3), nut seat (7) makes slip crate do lengthwise movement on lathe, finishes the function of numerical control of machine tools processing parts.Recover the original function of lathe if desired, only need nut (1) is unscrewed, because the effect clip (3) of compression spring (6) opens, it is that clip (3) is in opening that boss is thrown off from the outer garden groove of feed screw nut (8).Lathe can drive slip crate (11) along the lathe bed lengthwise movement by feed rod, rack-and-pinion according to motive power, transmission system, finishes work motor-driven, manual, processing parts.At this moment, because the moving of slip crate, feed screw nut (8) the empty rotation that only on ball-screw (9), accompanies.
The utility model uses on lathe and can make lathe both can realize the numerical control operation, can realize motor-driven, the manual working of former lathe again, has enlarged the accommodation of lathe.The utility model is simple in structure, easy to operate, can be widely used in microelectric technique and transforms in the machine tool.
Claims (1)
- A kind of ball-screw nut open-and-close mechanism of forming by ball-screw, feed screw nut, clip and nut seat, it is characterized in that having driven trough symmetrically at the cylindrical place of feed screw nut, feed screw nut is together packed into up and down movingly together with ball-screw in the nut seat of fluting, and the place of fluting up and down of nut seat is installed with a pair of clip that has the boss that can insert the feed screw nut peripheral groove by pin.
