Description
Technical field
The utility model relates to field of fixtures, especially a kind of self adaptation flat-nose pliers.
Background technology
Flat-nose pliers has another name called machine vice, is a kind of universal fixturing, is usually used in installing miniature workpiece, and it can be used in the processing such as filing, grinding, saw, drilling; It also can be used as the random annex of milling machine, grinding machine, is fixed on platen, is used for holding workpiece to carry out machining.
At present, common flat-nose pliers is primarily of fixing vice body, movable vise body, leading screw, jaw plate composition, and jaw plate is with fixing vice body, be all fixedly connected with between jaw plate with movable vise body.But due to jaw plate wearing and tearing, by the surface irregularity of holding workpiece own, transmission system gap error, by the existence of the situations such as the design feature of holding workpiece itself, cause jaw plate and can not fully be contacted between holding workpiece, contact surface is too small.When clamping work pieces, so that surface of the work is crushed.
Utility model content
Technical problem to be solved in the utility model is to provide one makes jaw plate fully contact with workpiece, avoids workpiece by the self adaptation flat-nose pliers crushed.
The utility model solves the technical scheme that its technical problem adopts: self adaptation flat-nose pliers, comprise fixed caliper, moving caliper and driving mechanism, described fixed caliper and moving caliper are slidably matched, and the projection of the clamping face of described fixed caliper and moving caliper in the plane perpendicular to the moving caliper direction of motion coincides, also comprise jaw plate one and hemisphere, the hemispherical plane of described hemisphere is fixedly connected with described jaw plate one, the clamping face of described moving caliper is provided with the groove matched with the sphere of described hemisphere, described hemisphere is provided with the ladder hole perpendicular to hemispherical plane, screw is provided with in described ladder hole, described screw and ladder hole matched in clearance, the outside diameter of described screw is greater than the diameter of aperture in ladder hole, be less than the diameter of macropore, and described screw runs through described ladder hole and is threaded with moving caliper.
The clamping face of described moving caliper is provided with two grooves, each groove respectively with the mating spherical surfaces of a hemisphere.
The clamping face of described fixed caliper is provided with jaw plate two, and size, the shape of described jaw plate two and jaw plate one are consistent.
Described jaw plate one and hemisphere are bolted to connection.
The nut that described driving mechanism is screw mandrel and is fixed as one with screw mandrel, described fixed caliper is provided with installation through hole, and described moving caliper is provided with tapped through hole, and described screw mandrel and described tapped through hole threaded engagement, be slidably matched with described installation through hole.
The beneficial effects of the utility model are: owing to there is mobile space between screw and the shoulder hole of hemisphere, hemisphere can freely swing within the specific limits along groove, when jaw plate wearing and tearing, be there is factor compared with wide arc gap error by the surface irregularity of holding workpiece own, transmission system time, hemisphere can drive jaw plate one automatic swing in certain angle to ensure fully to contact with by clamping face, to prevent workpiece from being crushed.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the A-A view of the utility model jaw plate one;
Fig. 3 is the partial enlarged drawing of the utility model part ii.
In figure, 1 is leading screw; 2 is nut; 3 is moving caliper; 4 is jaw plate two; 5 is fixed caliper; 8 is screw; 9 is hemisphere; 10 is jaw plate one; 11 is bolt; 12 is macropore, and 13 is the large end of screw; 14 is aperture.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in figures 1 and 3, self adaptation flat-nose pliers of the present utility model, comprise fixed caliper 5, moving caliper 3 and driving mechanism, described fixed caliper 5 is slidably matched with moving caliper 3, and the projection of clamping face in the plane perpendicular to moving caliper 3 direction of motion of described fixed caliper 5 and moving caliper 3 coincides, it is characterized in that: also comprise jaw plate 1 and hemisphere 9, the hemispherical plane of described hemisphere 9 is fixedly connected with described jaw plate 1, the clamping face of described moving caliper 3 is provided with the groove matched with the sphere of described hemisphere 9, described hemisphere 9 is provided with the ladder hole perpendicular to hemispherical plane, screw 8 is provided with in described ladder hole, described screw 8 and ladder hole matched in clearance, large end 13 diameter of described screw 8 is greater than the diameter of aperture 14 in ladder hole, be less than the diameter of macropore 12, and described screw 8 runs through described ladder hole and is threaded with moving caliper 3.
Driving mechanism, for promoting moving caliper 3, makes moving caliper 3 and fixed caliper 5 can clamping work pieces; The groove of moving caliper 3 and hemisphere 9 can matched in clearance, also can be slidably matched, due to screw 8 and the ladder hole matched in clearance of hemisphere 9, there is mobile space, hemisphere 9 can freely swing within the specific limits along groove, when jaw plate 1 wear and tear, be there is factor compared with wide arc gap error by the surface irregularity of holding workpiece own, transmission system time, hemisphere 9 can drive jaw plate 1 automatic swing in certain angle to ensure fully to contact with by clamping face, to prevent workpiece from being crushed.
Stable in order to what ensure that jaw plate 1 installs, the clamping face of described moving caliper 3 hemisphere is provided with two grooves, each groove respectively with the mating spherical surfaces of a hemisphere 9.A pair groove and hemisphere 9 are set, are fixedly connected with the two ends of jaw plate 1 respectively, can prevent jaw plate 1 from rotating, increase clamping dynamics simultaneously.
The clamping face of described fixed caliper 5 is provided with jaw plate 24, and size, the shape of described jaw plate 24 and jaw plate 1 are consistent.The jaw plate 24 that shape, size are identical and jaw plate 1 acting in conjunction, can improve the positional precision of workpiece.Fixed caliper 5 also can not arrange jaw plate 24, is directly clamped by caliper.
Jaw plate 24 and hemisphere 9 have multiple connected mode, and as welding etc., preferably, as shown in Figure 2, described jaw plate 1 is fixedly connected with by bolt 11 with hemisphere 9.Bolt attended operation is convenient, and adjustment is easy, and handling ease, be connected firmly.
Driving mechanism can adopt hydraulic-driven or motorized motions, preferably, the nut 2 that described driving mechanism is screw mandrel 1 and is fixed as one with screw mandrel 1, described fixed caliper 5 is provided with installation through hole, described moving caliper 3 is provided with tapped through hole, described screw mandrel 1 and described tapped through hole threaded engagement, be slidably matched with described installation through hole.Simply, cost is low, and manual operation more easily controls clamping degree for screw mandrel 1 and nut 2 structure.
