The positioning and locking of type workpiece, but under safer production environment, some miniature workpieces are moved to fixed position, together
The positioning and locking of Shi Shixian miniature workpieces, single-handedly completion is only needed manually, therefore, urgent need is a kind of only next by Manual-pushing and pulling
Realize the device for moving and being fixedly clamped of miniature workpiece.The common clamping device to miniature workpiece has the following disadvantages：It is dynamic
Power source makes the complicated of pressing device, production cost and use cost are higher using air pressure, hydraulic pressure, electronic, electromagnetic power；
The dynamics of clamping exists excessive, easily workpiece is caused to damage；Clamping force is uneven, poor to the locating effect of workpiece.
The content of the invention
It is an object of the invention to solve above-mentioned technical problem, there is provided a kind of self-centering fixing tool, have it is simple in construction,
Clamping effect is good, ensures the characteristics of workpiece quality.
In order to solve the above technical problems, present invention employs a kind of self-centering fixing tool, including pedestal, driving group, connection
Dynamic group and driven group, wherein, the driving group includes rotating shaft, the rotating shaft and the erecting bed axial rotation on the pedestal
Connection, the end that the rotating shaft extends downwardly from the erecting bed is provided with gear；The linkage groups include connecting rod and supports block, described to support
Block is connected with the pedestal vertical sliding motion and the upper end of the supports block is taper, and lower end is provided with to be slided with skewback set on the connecting rod
The dynamic skewed slot coordinated, the connecting rod are slidably connected with the base level, and the drive end of the connecting rod is provided with rack, the rack and
The gear engagement；The described driven group supporting table for including being fixed on the pedestal, the supporting table is interior to be provided with installation cavity, institute
State and be provided with clamping jaw in installation cavity, the inwall level of the clamping jaw and the installation cavity is slidably matched, and the clamping jaw is along the branch
Support platform is circumferentially evenly arranged with least two, and the drive end of the clamping jaw and the upper end of the supports block offset, and are set on the clamping jaw
There is latch plate, it is horizontal between the latch plate and the lateral wall of the installation cavity to be provided with compression spring.
Further, in above-mentioned technical proposal, the upper end of the rotating shaft is provided with retaining mechanism and handle.
Further, in above-mentioned technical proposal, axle sleeve is provided between the rotating shaft and the erecting bed.
Further, in above-mentioned technical proposal, the clamping jaw is circumferentially evenly arranged with three.
Beneficial effect possessed by the present invention：Due to circumferentially uniformly being exerted a force using by three clamping jaws, realize to workpiece inner wall
Clamping, there is the characteristics of clamping effect is good, while can be in inner hole of workpiece self-centering；Link motion is driven by gear, had
Effect transmits clamping force to clamping jaw, passes through the effect of the compression spring during supports block promotion clamping jaw, the chucking power of clamping jaw
Degree keep it is moderate, avoid workpiece because clamping force is excessive and caused by damage, ensured the quality of workpiece.
