Description
Technical field
The utility model belongs to field of fixtures, is specifically related to a kind of positioning clamping device of spheroid.
Background technology
Milling refers to the multiple-cutting-edge tool cutting workpiece using and rotate, be high efficiency processing method, during work, cutter rotates (primary movement), workpiece movable (doing feed motion), workpiece also can be fixed, but the cutter now rotated also must move (completing main motion and feed motion) simultaneously.
In the process of milling, need to use polytype clamping device, conventional adds man-hour to ball, usual employing sleeve type or jaw class fixture clamp, and when conventional sleeve or jaw class fixture clamping spherical work-piece, due to the rounding of spherical work-piece, make spherical work-piece in the process of clamping, can rotate around the centre of sphere, thus make the weak effect of clamping, fix tightly solidity is poor.
Utility model content
The technical problems to be solved in the utility model is that it easily rotates for the existing clamping device for spherical work-piece, the defect of fastness difference, provides a kind of clamping effect to cut well the positioning clamping device of the good spheroid of fastness.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: the positioning clamping device of spheroid, comprise pedestal, U-shaped fork, lower clamp and upper fixture, the bottom of U-shaped fork is embedded in pedestal, the side of U-shaped fork is left protruding end, the opposite side of U-shaped fork is right protruding end, left protruding end and the right protruding end of U-shaped fork are all positioned at above pedestal, bottom and the pedestal of U-shaped fork are hinged, the right protruding end side that pedestal is positioned at U-shaped fork is provided with fixed block, is provided with the lower positioning sliding block be connected with fixed block lower slide above right protruding end; Lower clamp comprises lower fixture block, lower V shaped slab, and lower end and the left protruding end of lower fixture block offset, and lower positioning sliding block is connected with lower fixture block, and lower V shaped slab is connected to lower fixture block top, and the V-shaped part of V shaped slab upward; Upper fixture comprises fixture block and upper V shaped slab, and the side of upper fixture block and the top of fixed block are slidably connected, and opposite side and the upper V shaped slab of upper fixture block are hinged, and the V-arrangement of upper V shaped slab is opening down, and the upper end of lower fixture block is provided with the push rod be connected with upper fixture block.
Adopt the positioning clamping device of the spheroid of technical solutions of the utility model, U-shaped fork is according to the pressure of the left protruding end of the pressure balance be subject to and right protruding end, when left protruding end is subject to the pressure of the lower fixture block that fixture block gives, pressure is passed in U-shaped fork by lower fixture block, due to U-shaped fork and pedestal hinged, therefore, after being under pressure, U-shaped fork is according to the balance shape of self, by the upwards lifting of right protruding end, to keep balance, power is upwards then transmitted to lower positioning sliding block after lifting by right protruding end, lower positioning sliding block then by power back transfer in upper positioning sliding block, upper positioning sliding block is owing to being subject to lifting force upwards, then power is transmitted to further connected upper fixture block, therefore, in order to maintain balance, upper V shaped slab rotates around the pin joint with upper fixture block, transmission of pressure is to spheroid again, pressure is continued to be transmitted to lower fixture block, continue to maintain balance, till spheroid is clamped.Compared with the clamping mode of existing chuck or jaw, clamping mode of the present utility model, can according to the clamping force of lower clamp in the large balance of pressure, and then the rotation avoiding spheroid to cause when discontinuity, fixation.
Further, the junction of described lower fixture block and lower positioning sliding block is provided with dovetail groove, and the junction of lower positioning sliding block and lower locating piece is provided with dovetail shaped projection, dovetail groove and dovetail shaped male cooperation.Dovetail groove connected mode dismounting, easy to connect, simple to operate.
Further, the lower end of described lower fixture block is provided with the jacking block offseted with left protruding end.The contact area of jacking block and left protruding end is little, and pressure is large.
Further, the inside contact surface of described upper V shaped slab and lower V shaped slab is equipped with multiple projection.Multiple projection contacts with surface of the work, increasing friction force, thus avoids spheroid to rotate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the schematic diagram of the positioning clamping device embodiment of the utility model spheroid.
Detailed description of the invention
In figure: left protruding end 1, right protruding end 2, lower fixture block 3, lower positioning sliding block 4, fixed block 5, upper fixture block 6, upper V shaped slab 7, lower V shaped slab 8.
As shown in Figure 1, the positioning clamping device of the utility model spheroid, comprise pedestal, U-shaped fork, lower clamp and upper fixture, the bottom of U-shaped fork is embedded in pedestal, the side of U-shaped fork is left protruding end 1, the opposite side of U-shaped fork is right protruding end 2, left protruding end 1 and the right protruding end 2 of U-shaped fork are all positioned at above pedestal, bottom and the pedestal of U-shaped fork are hinged, right protruding end 2 side that pedestal is positioned at U-shaped fork is provided with fixed block 5, is provided with the lower positioning sliding block 4 be connected with fixed block 5 lower slide above right protruding end 2; Lower clamp comprises lower fixture block 3, lower V shaped slab 8, lower end and the left protruding end 1 of lower fixture block 3 offset, the lower end of lower fixture block 3 is provided with the jacking block offseted with left protruding end 1, lower positioning sliding block 4 is connected with lower fixture block 3, lower fixture block 3 is provided with dovetail groove with the junction of lower positioning sliding block 4, and lower positioning sliding block 4 is provided with dovetail shaped projection, dovetail groove and dovetail shaped male cooperation with the junction of lower locating piece, lower V shaped slab 8 is connected to lower fixture block 3 top, and the V-shaped part of V shaped slab upward; Upper fixture comprises fixture block 6 and upper V shaped slab 7, the side of upper fixture block 6 and the top of fixed block 5 are slidably connected, opposite side and the upper V shaped slab 7 of upper fixture block 6 are hinged, and the V-arrangement of upper V shaped slab 7 is opening down, the upper end of lower fixture block 3 is provided with the push rod be connected with upper fixture block 6, and upper V shaped slab 7 and the inside contact surface of lower V shaped slab 8 are equipped with multiple projection.
In specific implementation process, ball is positioned in the V-shaped groove on lower V shaped slab 8, then fixture block 6 and upper V shaped slab 7 pressure is given, upper fixture block 6 pressure by lower fixture block 3 for the downward pressure of left protruding end 1, make jacking block give left protruding end 1 to press downwards, thus right protruding end 2 is upwards lifted, by lower positioning sliding block 4 along fixed block 5 upward sliding, fixture block 6 in lifting, after upper fixture block 6 upwards lifts, in drive, V shaped slab 7 is positioned at pin joint and moves down, continue again pressure to be transmitted to lower fixture block 3, repetition like this, maintain balance, until spheroid is clamped by upper V shaped slab 7 and lower V shaped slab 8, multiple projection then increasing friction force, make spheroid self-centering, keep fixing.
