Detailed description of the invention
Hereinafter, referring to the drawings and embodiment the present invention is described in detail:
As shown in Fig. 1 ~ 4, the outer holder clamping device of a kind of long tube kind part of weak rigidity, including being internally formed the base 13 of through hole, Described through hole inner radius is provided with multiple bearing, is provided with connecting bushing 12 in bearing inner race, and described connecting bushing 12 right-hand member sets It is equipped with support seat 10, supports seat 10 right-hand member and be provided with the support tapered sleeve 6 that internal diameter is from left to right gradually increased, described base 13 upper end Being provided with gripper shoe 15, gripper shoe 15 upper end is provided with hydraulic cylinder 1, and the piston rod of hydraulic cylinder 1 is connected with the cylinder rod on guide plate 3 Seat 2 is connected, and guide plate 3 left end is inserted in the pilot hole of base 13, is provided with right flange 5 below its right-hand member, and left flange 4 is with right Flange 5 matches the lock sleeve 7 that is fixedly clamped, and is provided with spring chuck 8 in lock sleeve 7 internal diameter, described spring chuck 8 outer wall with Support tapered sleeve 6 internal diameter composition sliding pair, described spring chuck 8 inwall clamping workpiece 9.
The multiple U-lag parallel with axis of uniform formation on the circumference of described spring chuck about 8 two ends.
The right baffle-plate 14 that described base 13 left end is provided with and limits connecting bushing 12, bearing left-hand moves, base 13 right-hand member It is provided with and limits the right baffle plate 11 that connecting bushing 12, bearing dextrad move.
