PAGE 32 棬磬涨 Abstract Machine Tool fixture design, should first of all parts of the map and parts of the components or assembly assembly,master of the components or parts in the assembly in the positi function or not, as well as parts of the assembly of the tech requirements of specific parts The main work surface to a point of order in the formulation process is to take measures to guarantee. In the machining process, using the method of processing machinery, the change in rough shape, size, location and mutual-facequality, making it a requirement to be completed using some parts of the process. In the processing machine parts, in order to be part of the process by processing the surface can achieve the required size and location of tolerance requirements, starting in machine for processing before, we must first make a correct position of the workpiece possession. Machine Tool fixture mechanical processing system is an important part. Workpiece clamping the accuracy, rapid, convenient and reliable, will directly parts of the processing quality, productivity, manufacturing costs and production safety. In bulk, mass production,workpiece clamping fixture through the machine to achieve. 3 6 7 7 7 8 . 29 32 33 , İ () () HT200 12-84-11164-M8 260 3桢桢棬0.02mm0.03mm 棬棬 5000顶21.1-2;豸豸 1 HT200顶412.2-5,繫CT-10 2 顶412.2-5MA-F2.2-4 CT D1105F1.5 107.4 10 D260F0.5262.410Z160F4 3 () 1 2 羫,顶201.4-71.4-81.4-11 1 棬D,DX51 2 D,D棬DDX51 3 D,D棬DDX51 4 60Z550 5 4-11Z550 6 4-166.3Z550 7 2-8Z550 8 4-M8Z550 9 20T232Z525 10 11 缰 1磺 60 4CT100.5IT859.53.33.53.5460.1IT859.93.20.3540.446 0 IT7603.00.0540.1304-11 0IT11111111.114-160IT10166.35.0752-80IT9888.0362湤磺 2.4CT1001, 0.2 105 6 1.5 7.7502D,D 0.7 61.7 10 1.5 7.7503D,D 0.5 60 7 1.8 6.383 1 棬D,D 1.
