The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:
As shown in Figure 2, the mutual upright opening of a kind of ultralong thin walled zirconium pipe is the milling built-up jig, and it comprises milling machine table 19; Calibration positioning jacket 11 before one end of milling machine table 19 connects; The other end connects back calibration positioning jacket 17, and preceding calibration positioning jacket 11 is installed in respectively on the support 18 with back calibration positioning jacket 17, on the preceding calibration positioning jacket 11 front rack 13 is installed; On the back calibration positioning jacket 17 tail-bracket 16 is installed, clamping device 14 and positioner 15 are installed on the milling machine table 19.
As shown in Figure 2; Be connected with front rack 13 and tail-bracket 16 on the milling machine table 19; Front rack 13 supports through support 18 with tail-bracket 16 bottoms; Preceding calibration positioning jacket 11 endwisely slips in the axial slideway of the sealing of front rack 13, and back calibration positioning jacket 17 endwisely slips in the axial slideway of the sealing of tail-bracket 16, is fixed with clamping device 14 and positioner 15 on the milling machine table 19 respectively; Preceding calibration positioning jacket 11 is clamped an end of workpiece 12, and the other end of workpiece 12 clamps through clamping device 14.
Each functional part of relevant built-up jig specifically describes as follows:
As shown in Figure 3; Chuck 32 before preceding calibration positioning jacket comprises; Support set 31 before preceding chuck 32 outer being set with, fluting cylinder screw 33 passes the sidewall of preceding support set 31 and preceding support set 31 and preceding chuck is fixed, and the sidewall of preceding support set 31 also is installed with the oval styletable holding screw 34 of fluting.
As shown in Figure 4; Back calibration positioning jacket comprises back support set 35; The back chuck 36 outer back support sets 35 that are set with, fluting cylinder screw 37 passes the sidewall of back support set 35 and also back support set 35 is fixed with back chuck 36, and the sidewall of back support set 35 also is installed with the oval styletable holding screw 38 of fluting.
Forward and backward calibration positioning jacket operation principle is to lean on the gap between movable intermediate plate and chuck to come clamping work pieces.Concrete job step is: unclamp that the oval styletable holding screw of fluting → workpiece inserts chuck hole → tighten the oval styletable holding screw of fluting → movable intermediate plate and the chuck gap dwindles clamping work pieces.Because chuck hole circle arc is consistent with the excircle of workpiece arc, its contact-making surface is big, and therefore, workpiece can not produce the caliber distortion under the clamping force effect.In order to prevent the axial float of chuck, support set and chuck are fixed together with a fluting cylinder screw.In addition, 4 90 ° of calibration pin-and-holes that are uniformly distributed with are arranged on the chuck, be fixed in the locating hole on the carriage, be used for the calibration and the axial location of workpiece circumferencial direction through latch.This device integrates two kinds of functions of calibration and location, changes two kinds of drawbacks that function can not be taken into account of calibration and location.Use this device to carry out calibration, location, can guarantee that the workpiece calibration is reliable, accurate positioning, and easy and simple to handle, can not crush workpiece.
As shown in Figure 5; Support 18 comprises plinth 46, is welded with equal leg angle 45 on the base 46, and the top of equal leg angle 45 is connected with support shank 42 through two groups of hex nuts 43 and hexagon-headed bolt 44; Be welded with U-shaped gripper shoe 41 on the support shank 42, the side of gripper shoe 41 has bolt hole.
