Abstract
The invention relates to a pair of bidirectional flat-nose pliers for a machine. When the bidirectional flat-nose pliers serve as a pair of double-jaw flat-nose pliers for a machine, the bidirectional flat-nose pliers can clamp two workpieces one time instead of one, the number of shutdown times is reduced, production efficiency is improved by more than one time, and the method is suitable for an occasion with a low requirement for centering of the workpieces; when the bidirectional flat-nose pliers serve as a pair of centering flat-nose pliers for a machine, axial displacement of a lead screw is precisely limited under the abutting effect of a front centering steel ball and a rear centering steel ball and the force applied by the two centering steel balls of two locking mechanisms jointly, and therefore precise centering of the workpieces is achieved. In this way, the bidirectional flat-nose pliers can achieve dual purposes.
Description
technical field
The present invention relates to a kind of flat-nose pliers using on lathe, be specifically related to a kind of machine Bidirectional flat-nose pliers.
background technology
Traditional machine vise, is called again machine vice, only has a jaw, once can only clamp a workpiece.Not only shut down number of times more, machine tool track concentrated wear is comparatively serious, and use is convenient not, and production efficiency is also very limited.On the other hand, its regular jaw seat single load bearing, easily fractures, and its service life is shorter, and cannot use as centering vice.
Summary of the invention
Technical problem to be solved by this invention is, a kind of machine Bidirectional flat-nose pliers is provided, and can either use again and can use as centering machine vise as two jaw machine vises, in order to overcome the deficiency of above-mentioned existing procucts.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme:
Machine Bidirectional flat-nose pliers, comprise base, be fixed on the vice body on base, regular jaw seat is installed on vice body, on vice body, offer X axis manhole, and in this manhole, leading screw is installed, in the left and right sides of vice body, be respectively arranged with left moving jaw seat and right moving jaw seat, these two moving jaw seats respectively with two of the left and right nut tight fit connection being socketed on leading screw, two sections of screw thread trends that leading screw matches with two of left and right nut are contrary, it is characterized in that: regular jaw seat is detachable.
In the centre position of leading screw, be processed with the ring groove of an arc shaped groove form; And each manhole before and after offering on described vice body, the axis of two manholes coincide and with the intersect vertical axis of leading screw; In each through hole, be respectively arranged with a centering plunger, the inner of centering plunger offers conical bore, in this conical bore, centering ball is installed, and matches with ring groove in the inner side of centering ball; Centering plunger outer end is installed with adjusting screw mandrel; Outer end opening position at described manhole is provided with hold-down nut, and the external screw thread of described hold-down nut matches with the internal thread of manhole, and the internal thread of hold-down nut matches with regulating screw mandrel; Also comprise and the adjusting nut that regulates screw mandrel external part to be threaded.
Good effect of the present invention is:
(1), while using as two jaw machine vises, the quantity of a holding workpiece is increased to two by one, and has reduced shutdown number of times, production efficiency is more than doubled, this form is suitable for the centering to workpiece and requires not too high place; While using as centering machine vise, at forward and backward centering ball, hold out against under effect, rely on two common application of forces of centering ball of two cover locking mechanisms, accurately limited the axial displacement of leading screw, thereby played the precision centering to workpiece.Realized dual-use.
(2), the left and right sides due to leading screw is designed with rightabout screw thread, during arbitrary end of rotating threaded shaft, two moving jaw seats all move and clamp two workpiece to regular jaw seat direction, two moving jaw seats are simultaneously to the middle application of force, the stressed of regular jaw seat is two-way, solved the problem that unidirectional force easily makes regular jaw seat bending distortion even fracture.
(3), increased the feed stroke of lathe, effectively reduced the concentrated wear of track.
Accompanying drawing explanation
Fig. 1 is that the present invention is as the structural representation of two jaw machine vises.
Fig. 2 is that the present invention is as the structural representation of centering machine vise.
Fig. 3 is the structural representation of leading screw axial positioning mechanism of the present invention.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the invention will be further described:
Embodiment mono-: the present invention is as the embodiment of two jaw machine vises.
As shown in Figure 1, the present embodiment comprises base l, is bolted on the vice body 4 on base 1, and detachable regular jaw seat 7 is installed on vice body 4.Detachable regular jaw seat 7 is installed and is positioned on vice body 4 by bolt and two cone pins.
On vice body 4, offer X axis manhole, and in this manhole, leading screw 3 is installed.In the left and right sides of vice body 4, be provided with two the moving jaw seats in left and right, be left moving jaw seat 9 and right moving jaw seat 5, these two moving jaw seats respectively with two of left and right nut 10 tight fit connections that are socketed on leading screw 3, two sections of screw threads trend that leading screw 3 matches with two of left and right nut 10 is contrary.
Two the moving jaw seats in left and right are slidably mounted on vice body 4 respectively in the X-axis.
When rotational lead screw 3, two of left and right nut 10 drives two the moving jaw seats in left and right to move to centre, coordinates respectively the workpiece clamping in two jaws with detachable regular jaw seat 7.
In the centre position of leading screw 3, be processed with the ring groove 6 of an arc shaped groove form, on the vice body 4 below described ring groove 6, along Y direction, offer circular hole, the unsteady steel ball 8 that spring 11 is installed in this circular hole and is withstood by spring 11.Steel ball 8 upper ends are stuck in this ring groove 6.
When the workpiece size of two the jaw clampings in left and right is inconsistent, the active force that leading screw 3 moves horizontally can be pushed steel ball 8 open, realizes floating of leading screw 3.
Embodiment bis-: the present invention is as the embodiment of centering machine vise.
As shown in Figure 2, in the present embodiment, the detachable regular jaw seat 7 of dismantling on the basis of embodiment mono-, and increase following leading screw axial positioning mechanism.
As Fig. 3, described leading screw axial positioning mechanism is as follows:
Each manhole before and after offering on described vice body 4, the axis of two manholes coincide and with leading screw 3 intersect vertical axis.In each through hole, be respectively arranged with a centering plunger 12, the inner of centering plunger 12 offers conical bore, and centering ball 13 is installed in this conical bore, matches with ring groove 6 in the inner side of centering ball 13.Centering plunger 12 outer ends are installed with and regulate screw mandrel 14.
Outer end opening position at described manhole is provided with hold-down nut 15, and the external screw thread of described hold-down nut 15 matches with the internal thread of manhole, and the internal thread of hold-down nut 15 matches with regulating screw mandrel 14.Also comprise and the adjusting nut 16 that regulates screw mandrel 14 external parts to be threaded.
Rotate two adjusting screw mandrels 14, inwardly promote two centering plungers 12, make two centering balls 13 withstand the middle ring groove 6 of leading screw, too tight, with very close to each other, be advisable.Finally lock two lock nuts 16, lead screw shaft is to not moving.
While needing two jaw machine vise function, be first totally released above-mentioned two centering balls 13, then load onto detachable regular jaw seat 7.Note, the steel ball 8 that floats, no matter use which kind of function of vice, is not all dismantled.
For easy to assembly and operate steadily, at the two ends, left and right of vice body, lining 2 has been installed.
