The quantity of described trapezoidal clamping screw is 2, and the quantity of described clamping screw via hole is 4, and trapezoidal clamping screw correspondence, through clamping screw via hole and pressing plate, screws with described clamp nut.
The quantity of described gusset is 4, is symmetrically distributed in described placenta surrounding, and with placenta centre bore for the center of circle, according to the diameter dimension of valve body excircle echelon formation, in the vertical direction be three grades stepped.
The effect of described head screwed hole is after process finishing, is conveniently taken out by mandrel.
Process a using method for the mold of welding butterfly valve body axis hole, comprise following three steps:
A. trapezoidal clamping screw is put into boring table dovetail groove, mandrel is arranged on workbench centre bore, utilizes coordinating of clamping screw via hole and trapezoidal clamping screw, is arranged on by placenta on boring table;
B. valve body is put into placenta, then pressing plate is placed on valve body, screw in clamp nut and valve body is compressed;
C. after utilizing boring cutter to process the axis hole of valve body one end, 180 ° rotate boring table, the axis hole of the processing valve body other end.
When utilizing mold of the present invention to process welding butterfly valve body axis hole, there is following characteristics:
1. mold handling are simple, convenient to use;
2. can being fixed on central line of table from being about to valve axis, saving the time of valve body clamping centering, improve production efficiency, effectively shortening the production cycle of product, solving Set and Positioning problem during batch machining simultaneously;
3. mold all adopts small―gap suture to coordinate with each location place of valve body, workbench, and make axiality and the symmetry of valve body axis hole, and all meet technical requirement with the perpendicularity of valve body end face, the quality of product is more reliable and more stable.
