It is provided with the second centering pin and the 3rd centering pin on the line in the center of circle, the distance of first positioning pin and the first centering pin,
Second positioning pin and the distance of the second centering pin and the 3rd positioning pin are identical with the distance of the 3rd centering pin, the chassis it is upper
Surface is evenly arranged with several pressing plates, and pressing plate is connected with chassis by studs.
The outer end of the sliding block is arranged in the groove at chassis edge.
First fixing piece is "Ji" type.
The pressing plate is provided with 8.
Compared with prior art, it is as follows the advantages of the utility model：
The utility model is by setting the first positioning pin so that the first positioning pin is cast as sliding block is along moving radially
Benchmark first positions finger setting, then the position by adjusting sliding block using second and the 3rd, makes the first positioning pin along footpath in positioning
To outwards withstanding part, then tightening housing screw fixes the first positioning pin, is eliminated or weakened due to benchmark molten error with this
The position gap of generation, so as to improve the fit precision of positioning fixture and part, controls part machining deformation.
After the utility model casting origin reference location, centering can be carried out by 3 centering pins, can be to avoid conventional positioning fixture
After positioning can not centering the problem of, due to adding part centering, thus improve part machined surface with cast benchmark position degree,
Improve the precision of part processing.
