Abstract
The invention relates to a using method of a positioning clamp for turning a conical face. The method includes the steps that first, a positioning column of a base is sleeved with a workpiece, and a boss in an inner cavity of the workpiece is enabled to be matched with a groove in the outer circle of the positioning column; second, a positioning block presses a shoulder in the inner cavity of the workpiece through a screw, and the workpiece is axially positioned; third, a base plate on the base is clamped through a three-jaw chuck on a machine tool, and clamping of an outer circle of the workpiece is avoided; the workpiece and the base rotate together, and the conical face of the outer circle of the workpiece is turned. The using method is simple in structure, economical, practical and high in machining efficiency.
Description
Technical field
The present invention relates to technical field of tooling clamps, particularly relate to a kind of using method of the positioning tool for turning shell workpiece outer conical surface.
Background technology
The workpiece 1 of thin wall class is as shown in Figure 1 when carrying out the turning conical surface 11 to it, general processing method is that the cylindrical section 14 of workpiece 1 is held on the scroll chuck of lathe, but because this type of workpiece 1 cylindrical wall is thinner, if carry out clamping with lathe chuck, workpiece very easily deforms, particularly be obviously for the precision workpiece that required precision is higher, cause machining accuracy undesirable.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, provide a kind of using method of car conical surface positioning fixture, its structure is simple, and economical and practical, machining accuracy is high.
The technical solution adopted in the present invention is as follows:
The using method of car conical surface positioning fixture, comprises the steps:
The first step, is enclosed within workpiece in the locating dowel of pedestal, and make boss in workpiece lumen respectively with the fit depressions on locating dowel cylindrical;
Second step, by screw by the convex shoulder in locating piece workpiece pressing inner chamber, carries out axial location to workpiece;
3rd step, makes the chassis in the scroll chuck clamp base of lathe, avoids the clamping with excircle of workpiece; Workpiece rotates together with pedestal, machines the outer conical surface of workpiece.
The invention has the advantages that: process the groove that can match with the inner chamber boss of workpiece at the locating dowel circumference of pedestal, workpiece is applied to the effect of circumferencial direction power, at locating dowel end face, locating piece is installed, the dome in positioning workpieces on cavity wall simultaneously, axially workpiece is being positioned; Avoid excircle of workpiece at radial direction stress deformation, ensure machining accuracy, structure is simple, and economical and practical, machining accuracy is high.

Fig. 1 is the front sectional view of workpiece.
Fig. 2 is the stereogram of pedestal of the present invention.
Fig. 3 is the stereogram before the present invention uses.
Fig. 4 is the state diagram of the present invention when using.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figures 1 to 4, the present invention includes and comprise pedestal 2, pedestal 2 has chassis 21, is adding man-hour, and the scroll chuck of lathe is clamped chassis 21, avoids the effect cylindrical of workpiece 1 being applied to radial load, chassis 21 there is locating dowel 22, the uniform groove 24 of cylindrical of locating dowel 22, groove 24 matches with the uniform boss of cavity wall 12 in workpiece 1 and both quantity is identical, in the process of processing, locating dowel 22 applies the effect of circumferencial direction power by groove 24 pairs of workpiece 1, make workpiece 1 with pedestal 2 together High Rotation Speed, groove 24 extends to the upper surface 25 of locating dowel 22, with locating hole 23 on described upper surface 25, described upper surface 25 is provided with locating piece 3, locating piece 3 can be designed to three claw types, also can be disc, locating piece 3 to be arranged on the upper surface 25 of locating dowel 22 by screw 4 and to push down on the convex shoulder 13 in workpiece 1 inner chamber, axial location clamping is carried out to workpiece 1,
Method of operating of the present invention is as follows:
The first step, is enclosed within workpiece 1 in the locating dowel 22 of pedestal 2, and the boss 12 in workpiece 1 inner chamber is matched with the groove 24 on locating dowel 22 cylindrical respectively;
Second step, by screw 4 by the convex shoulder 13 in locating piece 3 workpiece pressing 1 inner chamber, carries out axial location to workpiece 1;
3rd step, makes the chassis 21 in the scroll chuck clamp base 2 of lathe, avoids the clamping with excircle of workpiece 14; Workpiece 1 rotates together with pedestal 2, machines the outer conical surface 11 of workpiece 1.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
