Clamping workpiece, with three-jaw self-centering chuck clamping workpiece, with four-jaw chuck clamping workpiece.Because of product requirement, need
Milling Process is carried out on the eccentric shaft processed, this just needs to product effectively position and fix, and to process, and shows
Some clamping methods are clamped using Bidirectional flat-nose pliers positioning, or carry out clamping using three-jaw self-centering chuck mode.But these
Clamping positioning method is all difficult to ensure its precision on position degree and symmetry, and discontinuity then will produce deformation, dress
The folder time is longer, and efficiency is low.
For Mechanical Product's Machining, usual bulk article is if single processing, the much time on product clamping
Power, and Product Precision and dimensional uniformity it is difficult to ensure that, efficiency is low.It is cost-effective in order to improve efficiency, it is sought in product handling
It asks and shortens the time.Existing fixture scheme is to use fixture last time clamping more than one piece product, is processed, but this method is same
Sample needs piecemeal individually tighten independent release, discontinuity, be susceptible to clamping force not enough or Overexertion to
Lead to product rejection, the assembly and disassembly period is longer, low production efficiency.
