Abstract

The utility model provides ''anti-upward-warping'' flat-nose pliers for a machine, comprising: a fixed jaw (1), a clamp body (2), a leading screw (3), a movable clamp body (4), a movable jaw (5), a compression spring (6), and a limiting screw; the ''anti-upward-warping'' flat-nose pliers are characterized in that, the movable jaw (5) and the movable clamp body (4) are in an inclined plane contact. The defect of workpiece ''upward-warping'' during clamping of the flat-nose pliers with ''the leading screw being disposed at the lower part'' is overcome. The inclined structure of the movable jaw (5) being in a contact with the movable clamp body (4) is adopted. When the flat-nose pliers are used to clamp a workpiece, the movable jaw (5) generates a downward pressure and moves downward, and the workpiece bears downward pressure at the side of the movable jaw (5), overcoming the defect of workpiece ''upward-warping'' during clamping of the flat-nose pliers. The ''anti-upward-warping'' flat-nose pliers for the machine are also advantaged by simple structure and convenient operation.

Description

" anti-upwarping " machine vise
Technical field
The utility model belongs to machining universal fixturing machine vise, is specifically related to " anti-upwarping " machine vise.
Background technology
Machine vise is to use one of the widest universal fixturing in the mechanical processing process, and is easy to operate, cost is low, easy-maintaining, but a kind of defective of ubiquity, i.e. the defective that " upwarps " of workpiece.The existing general using method of machine vise is: knock workpiece when clamping work pieces, the workpiece positioning datum is overlapped fully with the flat-nose pliers datum level.But workpiece still can produce " upwarping " in the moving jaw side, thereby can't guarantee the workpiece precise positioning, more can't guarantee the workpiece machining high-precision.
Summary of the invention
Defects when having the machine vise clamping workpiece now in order to solve, the utility model provide " anti-upwarping " machine vise.The utility model is by changing existing flat-nose pliers building block topology layout, operation principle, that is: with being fixedly connected with of former machine vise moving caliper and moving jaw, changing into " preventing upwarping " machine vise moving caliper and contact with the inclined-plane with moving jaw; Compress Spring and spacing connection of stop screw auto back redoubling make moving jaw produce downforce, by the frictional force of jaw and workpiece, make workpiece to moving down not " upwarping ", produce " anti-upwarping " machine vise.
" anti-upwarping " machine vise building block mainly comprises: regular jaw, caliper, leading screw, moving caliper, moving jaw, Compress Spring, stop screw; Its advantage is: during the flat-nose pliers clamping work pieces, contact between moving jaw and the moving caliper and produce active force between the inclined-plane, moving jaw is moved down, drive simultaneously workpiece and move down, workpiece can " not upwarp ";
The angle of inclination that contacts the inclined-plane between moving jaw and the moving caliper is decided to be 70 °;
When jaw unclamped, the pin-and-hole between moving jaw and the moving caliper was for Compress Spring automatically replies, and moving jaw is moved on the moving caliper inclined-plane, and moving jaw moves down the gap is provided during for the flat-nose pliers clamping work pieces;
Realize the function of " anti-upwarping " machine vise, its core is improved and is comprised three: one be moving jaw with moving caliper between contact the inclined-plane the angle of inclination be decided to be 70 °;
It is two for when jaw unclamps, and the pin-and-hole between moving jaw and the moving caliper is to automatically reply for Compress Spring, and moving jaw is moved on the moving caliper inclined-plane, and moving jaw moves down the gap is provided during for the flat-nose pliers clamping work pieces;
It three is the stop screw syndeton of moving jaw and the rational deployment of above-mentioned three associated components, guarantee that " anti-upwarping " is when machine vise clamps, the amount of moving down that moving jaw produces is greater than the amount of moving in the moving caliper generation, make workpiece be subjected to all the time the downforce effect, guarantee that workpiece " does not upwarp ".
Beneficial effect: by improving " anti-upwarping " machine vise building block topology layout, operation principle, analyzing to produce makes workpiece " upwarp " reason, formulate " anti-upwarping " machine vise " anti-upwarping " organization plan, through the actual processing of building block, assembling, debugging, when using " anti-upwarping " the machine vise clamping workpiece after improving, accurate positioning, clamping are firm, during Precision Machining, can not affect workpiece size, the accuracy of form and position because workpiece " upwarps ", can be widely applied in the precision optical machinery process.

Fig. 2 is the front view of moving caliper 4.
Fig. 3 is the top view of moving caliper 4.
Fig. 4 is the front view of the formation schematic diagram of moving jaw 5.
Fig. 5 is that the A of formation schematic diagram of moving jaw 5 is to view.
The specific embodiment
Embodiment 1 is shown in accompanying drawing 1-5, and the utility model provides " anti-upwarping " machine vise.The utility model is by changing existing flat-nose pliers building block topology layout, operation principle, that is: with being fixedly connected with of former machine vise moving caliper 4 and moving jaw 5, changing into " anti-upwarping " machine vise moving caliper 4 and moving jaw 5 and contact with the inclined-plane; Compress Spring 6 and spacing connection of stop screw auto back redoubling make moving jaw 5 produce downforce, by the frictional force of jaw and workpiece, make workpiece to moving down not " upwarping ", produce " anti-upwarping " machine vise.
" anti-upwarping " machine vise building block mainly comprises: regular jaw 1, caliper 2, leading screw 3, moving caliper 4, moving jaw 5, Compress Spring 6, stop screw, its advantage is: during the flat-nose pliers clamping work pieces, contact between moving jaw 5 and the moving caliper 4 and produce active force between the inclined-plane, moving jaw 5 is moved down, drive simultaneously workpiece and move down, workpiece can " not upwarp ";
The angle of inclination that contacts the inclined-plane between moving jaw 5 and the moving caliper 4 is decided to be 70 °;
When jaw unclamped, the pin-and-hole between moving jaw 5 and the moving caliper 4 was for Compress Spring 6 automatically replies, and moving jaw 5 is moved on moving caliper 4 inclined-planes, and moving jaw 5 moves down the gap is provided during for the flat-nose pliers clamping work pieces;
Realize the function of " anti-upwarping " machine vise, its core is improved and is comprised three: one be moving jaw 5 with moving caliper 4 between contact the inclined-plane the angle of inclination be decided to be 70 °;
It is two for when jaw unclamps, and the pin-and-hole between moving jaw 5 and the moving caliper 4 is to automatically reply for Compress Spring 6, and moving jaw 5 is moved on moving caliper 4 inclined-planes, and moving jaw 5 moves down the gap is provided during for the flat-nose pliers clamping work pieces;
It three is the rational deployment of moving jaw 5 stop screw syndetons and above-mentioned three associated components, guarantee that " anti-upwarping " is when machine vise clamps, the amount of moving down that moving jaw 5 produces is greater than the amount of moving in moving caliper 4 generations, make workpiece be subjected to all the time the downforce effect, guarantee that workpiece " does not upwarp ".
