The other end is welded with grip block 31, and the side that grip block 31 is bonded with workpiece is provided with rubber layer 36, for increasing clamping
Frictional force between plate 31 and workpiece, while grip block 31 being avoided to cause scratch to workpiece when clamping, the setting of fixed plate 32 is the
It between three threaded holes 33 and grip block 31, can be moved on support arm 30, between fixed plate 32 and grip block 31 there are two settings
Spring 34, spring 34 are separately positioned on the both ends of grip block 31, and the head end of spring 34 is fixedly connected with fixed plate 32, spring 34
Tail end is fixedly connected with grip block 31, pushes fixed plate 32 and grip block 31 that spring 34 is made to be in impaction state, spring 34 can
Extruding force is generated to grip block 31, to increase grip block 31 to the chucking power of workpiece, fixed plate 32 and third threaded hole 33 it
Between be provided with third nut 35, be provided with the external screw thread matched with third nut 35 on the outside of support arm 30, third nut 35 is used
In the position of limitation fixed plate 32, so that spring 34 is in impaction state in clamping always, it is lasting to the formation of grip block 31
Extruding force is conducive to grip block 31 to the stable holding of workpiece.
In use, the threaded post 2 that four are equipped with clamp assemblies 3 can be respectively moved to four ends of two dovetail grooves 11
Workpiece to be held, is placed on the center of two dovetail grooves 11 on pedestal 1 by point position, to the mobile one of dovetail in workpiece direction
Threaded post 2 in slot 11 adjusts second so that threaded post 2 slides into suitable position along dovetail groove 11 under the action of sliding block 4
Nut 22 and bung flange 21 screw corresponding first nut 23 and make spiral shell so that grip block 31, which is in, to be bonded with workpiece to be held
Line column 2 and pedestal 1 are fixed, screw corresponding second nut 22 and to fix between support arm 30 and threaded post 2, movement is same
Another opposite threaded post 2 is bonded the grip block 31 in the threaded post 2 with workpiece to be held in dovetail groove 11, adjusts simultaneously
21 fixed clamp component 3 of the second nut 22 and bung flange is screwed, compression clamping plate 31 screws phase after making workpiece be in steady status
The first nut answered
23 make the threaded post 2 and pedestal 1 fixed, push two fixed plates 32 that spring 34 is made to be in impaction state back spin
Tight third nut 35, limits the position of fixed plate 32, the spring 34 of compression makes grip block 31 further to the chucking power of workpiece
Enhancing.Other two threaded post 2 in another dovetail groove 11 is moved again, so that two opposite grip blocks 31 are further to work
Part carries out stable holding, and four grip blocks 31 carry out welding safely and efficiently the stable holding of workpiece, should
Device can realize the irregular workpiece of stable holding various shapes, can also to avoid artificial fixed workpiece bring security risk
It avoids unstable because clamping caused by irregular shape, influences welding efficiency.
Further, grip block 31 includes floor section 311, and the both ends of floor section 311 are symmetrically arranged with tilting section 312, incline
