Specific embodiment
Below with reference to diagram, preferred embodiments of the present invention will be described.
Embodiment 1:
As illustrated in fig. 1 and 2, a kind of clamp for machining of thin-wall round workpiece, including the bottom being mounted in machine tooling equipment
Plate 1, the supporter 2 being mounted on bottom plate 1, several fixed pivots 3 being mounted on supporter 2, the work being mounted on supporter 2
Activity supporting point 4 and limit shaft 5 are mounted on limit shaft 5 and moving fulcrum 4 are driven to do the adjusting block 6 of alternating translational and assign into
The adjustment threaded rod 7 cooperated on supporter 2 and with adjusting block 6.
The supporter 2 is at hollow cylinder.One end of the supporter 2 is mounted on bottom plate 1；Other end center
It is equipped with supporting plate 8.The adjustment threaded rod 7 is mounted on the supporting plate 8.
Several fixed pivots 3 can be along the axial direction distribution of supporter 2, can also be along the circumferencial direction of supporter 2 point
Cloth.It looks up from the axis of supporter 2, the fixed pivot 3 is to be uniformly distributed in the circumferencial direction of supporter 2 with moving fulcrum 4
's.
The moving fulcrum 4 is at T font comprising main part 9 and main body 9 extend vertically the support portion 10 to be formed.
Spring 11 is arranged on the support portion 10 of the moving fulcrum 4.The spring 11 is between moving fulcrum 4 and supporter 2.Institute
Stating moving fulcrum 4 is internally mounted on supporter 2 from supporter 2, i.e., the support portion 10 of moving fulcrum 4 is out of supporter 2
Portion passes through supporter 2.
The limit shaft 5 is arranged in the inside of supporter 2 and perpendicular to the axial direction of supporter 2.The limit shaft 5 can
By welding or being threadedly secured on supporter 2.The moving fulcrum 4, limit shaft 5 and adjustment threaded rod 7 are mutually perpendicular to pacify
It fills on supporter 2.
The adjusting block 6 is equipped with the limit hole 12 passed through for limit shaft 5.The limit hole 12 is elongated hole.The limit
Position axis 5 slides in limit hole 12.Described 6 one end of adjusting block is equipped with the threaded hole cooperated with adjustment threaded rod 7.
It is connected between the other end of the adjusting block 6 and the main part 9 of moving fulcrum 4 by connecting rod 13.The connecting rod 13
It is connected on adjusting block 6 and moving fulcrum 4 by pin shaft 14.
Clamp for machining application method of the invention is as follows: first thin-wall round workpiece being set on supporter 2；Then on one side
Thin-wall round workpiece is resisted against on fixed pivot 3, another side rotation adjustment threaded rod 7；It adjusts threaded rod 7 and drives adjusting block 6
Along the axial movement of supporter 2, adjusting block 6 is driven by connecting rod 13 to moving fulcrum 4, and 4 compressed spring 11 of moving fulcrum is to branch
