Description
Technical field
The utility model relates to technical field of tooling clamps, relates in particular to a kind of positioner for the thin-walled tubular workpiece being carried out turning processing.
Background technology
Carry out turning for the thin-wall pipe of as shown in Figure 1 longer size and add man-hour, in order to prevent workpiece deformation, usually adopt fixed axis insertion tube intracavity to position from the two ends of pipe fitting, although this type of locate mode can be avoided the distortion of pipe fitting preferably, but can not be from reducing to the full extent distortion to the impact of machining accuracy, especially still can there be the defective of deformation effect machining accuracy in the pipe fitting thinner for inwall, that Length Ratio is larger.
The utility model content
The utility model provides a kind of shell workpiece turning frock for above-mentioned shortcoming of the prior art, and it is simple in structure, and is economical and practical, and machining accuracy is high.
The technical scheme that the utility model adopts is as follows:
Tubular workpiece high accuracy turning positioning device, comprise fixed axis, fixed axis has gripping section and positioning section, on gripping section with the location dome, positioning section has endoporus, and the bottom of endoporus is provided with the chock with screw rod, is provided with movable block in endoporus, the top of movable block is with tapering point, and the root of movable block is with external screw thread; Overlap to have to insert on positioning section and match with the end face of workpiece, fixture is installed on the root of movable block withstands the end face of inserting; Inserting voussoir on positioning section matches with tapering point on movable block;
Further technical scheme is as follows:
Be inserted with 2 or 3 voussoirs on described positioning section;
Described fixture is nut.
The utility model has the advantage of: the location dome is set on the gripping section of fixed axis and is set with on positioning section and insert, pipe fitting is carried out the location, two ends; Match with movable block in the positioning section endoporus inserting voussoir on positioning section simultaneously, voussoir can position from the interior cavity wall of pipe fitting, increases a support to pipe fitting, prevents that lathe tool from applying the masterpiece used time to the pipe fitting cylindrical, pipe fitting deforms, and guarantees the machining accuracy of cylindrical; Simple in structure, economical and practical, machining accuracy is high.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1 to Figure 3, the utility model comprises fixed axis 1, fixed axis 1 has gripping section 11 and positioning section 12, on gripping section 11 with the location dome 2, positioning section 12 has endoporus 10, and the bottom of endoporus 10 is provided with the chock 3 with screw rod 9, is provided with movable block 5 in endoporus 10, the top of movable block 5 is with tapering point 51, and tapering point 51 has internal thread hole; The root 7 of movable block 5 is with external screw thread; On positioning section 12, cover has to insert and 6 matches with the end face of workpiece 13, on the root 7 of movable block 5, fixture 8 is installed and withstands 6 the end face of inserting, and fixture 8 can contain for nut etc. the securing member of internal thread; Insert 3 or 4 voussoirs 4 on positioning section 12 and match with tapering point 51 on movable block 5, the bottom of voussoir 4 is that the conical surface of inclined-plane and tapering point 51 matches.
Use method of operating of the present utility model is as follows:
The first step is put into chock 3 in the endoporus 10 of positioning section 12, make screw rod 9 outside;
Second step inserts voussoir 4 in the installing hole on positioning section 12;
The 3rd step, the tapering point 51 of movable block 5 is inwardly inserted in the endoporus 10 of positioning section 12, the movable block 5 of walking around makes the internal thread hole of its tapering point 51 coordinate with screw rod 9;
The 4th step was enclosed within pipe fitting 13 on positioning section 12, and just an end of pipe fitting 13 and location dome 2 close-fittings on gripping section 11 put at the cylindrical of positioning section 12 and insert 6, made 6 the outer face of pushing down pipe fitting 13 of inserting;
The 5th step was further rotated movable block 5, made its tapering point 51 with voussoir 4 jack-up, and voussoir 4 enters the inwall that withstands pipe fitting 13 in the groove of pipe fitting 13 inner chambers;
The 6th step, mounting fixing parts 8 on the root 7 of movable block 5, nut 8 and 6 the end face close-fitting of inserting;
The 7th step was clipped in gripping section 11 on the scroll chuck of lathe, made pipe fitting High Rotation Speed together with fixed axis 1, and pipe fitting 13 is carried out turning processing.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
