Straight pin 7, straight pin 8, sliding block 9, base 10, leading screw 11 and centering block 12, pivoted arm 1 are arranged on sliding block 9 by bearing 4, are turned
A rocker piece 2 is respectively installed at the both ends of arm 1, is connected between rocker piece 2 and pivoted arm 1 by the first threaded 3, and two rocker pieces 2 are with turning
Arm 1 forms the rotation of Y-direction；Pivoted arm 1 forms the rotation in Z1 directions with bearing 4 by the second threaded 5；On each rocker piece 2
Respectively one two-sided pressure head 6 of installation, two two-sided pressure heads 6 are connected with rocker piece 2 by the first straight pin 7 below, are on two-sided pressure head 6
It is the rotation that Z2 directions are formed by hole on mating holes, rocker piece 2；The rotation in Z1 directions and Z2 directions passes through in pivoted arm 1, double
A ring-type slotted hole is opened in face pressure first 6 coordinates the second straight pin 8 to realize that the anglec of rotation is spacing, and the rotation of Y-direction passes through pivoted arm 1
Top and bottom realize that the anglec of rotation is spacing；Bearing 10 is spirally connected with sliding block 9, and sliding block 9 slides in the T-slot of base 10；When for
When the profile-followed clamping device of multiple spot of black skin is two pawl, two sliding blocks 9 are connected by leading screw 11, and a left side is formed with one of sliding block 9
Revolve screw thread with 11 left-handed end of leading screw to coordinate, right-handed thread is formed with another sliding block and is coordinated with the dextrorotation end of leading screw 11；Made on leading screw 11
There is centering annular groove to coordinate with centering block 12, ensure the centerings of two clamping jaws during assembling to realize self-centering.
The beneficial effects of the utility model：Have be servo-actuated at two or three 8 points on the profile-followed clamping device of multiple spot for black skin
Hold-down mechanism.Mechanism cleverly make use of the general principle of symmetrical lever, and fixed clamping jaw is changed into Y, Z1, Z2 both direction
Floating platen structure on three positions.A clamping point is changed into eight and compress point and eight clamping points can effectively and work
Part contacts.According to the principle of symmetrical lever, the stress of eight clamping points is all equal, is eight by F points original of a clamping point power
Individual clamping point power, the active force f=F/8 of each clamping point.F thus can be increased and be evenly distributed in the table of part
Face.Self-centering clamping is realized by left-right turning screw rod transmission or Archimedian screw transmission.The utility model solves aircraft
Part medium casting clamps unreliable and Workpiece clamping problem on deformation with forging part.It can realize that clamping point uniformly divides with clamping force
Cloth, and self-centering can be realized.
