Detailed Description
As shown in fig. 2 to 5, a hydraulic fixture for end cover part machining center, including base 1, be equipped with juxtaposed mounting bracket 3 that is used for clamping end cover 2 on base 1, the top of mounting bracket 3 is equipped with tube-shape limiting plate 4, the last ring of end cover 2 cooperatees with the through-hole of limiting plate 4, the bottom that is close to mounting bracket 3 is equipped with the clamping mechanism who presss from both sides the lower ring of tight end cover 2, the outside of mounting bracket 3 is equipped with a pair of relative cylinder 5 that compresses tightly, the clamp plate 6 is connected to the piston rod that compresses tightly cylinder 5, two cylinders 5 that compress tightly drive the last ring outer fringe department of the lower pressure end of clamp plate 6 and end cover 2 and compress tightly. Vertically putting into in the through-hole of limiting plate 4 with end cover 2, through the lower ring of clamping mechanism clamp end cover 2, two relative compress tightly cylinder 5 drives clamp plate 6 and compresses tightly the last ring outer fringe department of end cover 2 of rethread to accomplish the clamp of end cover 2 and press from both sides fixedly, through this kind of tight mode of clamp, not only clamping stability is good, can effectively prevent simultaneously with end cover extrusion deformation, improved the machining precision of follow-up end cover.
