Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 7, the processing mold of brake piston, comprises upper bolster 11, core rod 12, drift positioning seat 21 and drift 22.The middle part of upper bolster 11 offers accommodating hole 13, and core rod 12 is located in accommodating hole 13.The internal diameter of accommodating hole 13 and the external diameter of core rod 12 match.The end face of core rod 12 and the end face of upper bolster 11.Drift positioning seat 21 offers centre bore, and the bottom of drift 22 is located in the centre bore of drift positioning seat 21.The central axis of core rod 12 and the central axis of drift 22 are on same straight line.Upper bolster 11 offers the first locating hole 111, drift positioning seat 21 offers the second locating hole 211.
As shown in Figure 1, the muscle 61 on the inner hole wall of brake piston 6 and the groove 62 on brake piston bottom surface need on the same line.
As shown in figures 2-3, drift location-plate 3 offers the first drift locating hole 31 and the second drift locating hole 32.Second drift locating hole 32 is open pore, is convenient to after drift 22 fixes, remove drift location-plate 3.
By as follows for the step that drift positioning seat is put in drift location:
Step 1: drift location-plate 3 is set on drift 22, makes drift 22 be located in the second drift locating hole 32 of drift location-plate 3, is inserted by alignment pin 5 in first locating hole 31 of drift location-plate 3;
Step 2: inserted the bottom of drift 22 in the centre bore of drift positioning seat 21, inserted by the alignment pin 5 be inserted in drift location-plate 3 in the 3rd drift locating hole 211 of drift positioning seat 21 meanwhile, realizes location;
Step 3: extract alignment pin 5, removes drift location-plate 3, and drift 22 is accurately positioned and is fixed in drift positioning seat 21.
