Abstract
The invention relates to a using method of a positioning clamp for high-precision external circle turning. The using method comprises the steps that firstly, a clamping section of a positioning column is clamped to a chuck of a turning lathe; secondly, a workpiece is installed in a square groove; thirdly, a positioning cap is installed to a threaded section of the positioning column; fourthly, turning is carried out on the external circle of the cylindrical body of the workpiece through hole turning. According to the using method, the positioning clamp is simple in structure, easy and convenient to operate and high in positioning and machining precision.
Description
Technical field
The present invention relates to technical field of tooling clamps, particularly relate to the using method that a kind of precision workpiece carries out the positioner of finish turning processing.
Background technology
Workpiece 1 as shown in Figure 1, workpiece 1 comprises square floor 11, vertical with cylinder 12 on base plate 11, cylinder 12 has locating hole 13, now need as requested to carry out fine finishining to the cylindrical of cylinder 12, not easily the modes such as Milling Machining are adopted for this type of form workpiece 1, Vehicle Processing is usually used in carrying out thick finish turning processing to cylinder cylindrical, but the size of workpiece 1 is less and with square floor 1, not easily direct clamping is carried out to workpiece 1, need special tooling, just easily ensure the fine finishining precision of workpiece 1 cylinder 12 cylindrical.
Summary of the invention
The present invention is directed to the problems referred to above of the prior art, provide a kind of using method of High-precision vehicle excircle orientation fixture, its structure is simple, easy and simple to handle, and location machining accuracy is high.
The technical solution adopted in the present invention is as follows:
The using method of High-precision vehicle excircle orientation fixture, comprises the steps:
The first step, by the gripping section clamping of locating dowel on the chuck of lathe;
Second step, is loaded on workpiece in square groove;
3rd step, is filled to positioning cap on the thread segment of locating dowel;
4th step, is machined by the cylindrical cylindrical of car hole to workpiece.
The invention has the advantages that: setting party's connected in star on locating dowel upper surface and in groove, straight pin is set, workpiece is accurately located, the cylindrical of locating dowel has simultaneously attacked external screw thread, with the screw-internal thread fit of positioning cap, has taken workpiece by force and carry out axial location; Structure of the present invention is simple, easy and simple to handle, and location machining accuracy is high.
Accompanying drawing explanation
Fig. 1 is the stereogram of workpiece.
Fig. 2 is the stereogram of locating dowel of the present invention.
Fig. 3 is the stereogram of positioning cap of the present invention.
Fig. 4 is using state figure of the present invention.
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 locating dowel 2 and positioning cap 3, the cylinder 21 of locating dowel 2 is divided into gripping section and thread segment, described gripping section is for being clamped to the chuck of lathe by cylinder 21, with square groove 22 on the end face of described thread segment, with straight pin 23 and gas hole 24 in square groove 22, groove 22 can coordinate with the base plate 11 of workpiece 1, straight pin 23 coordinates with the locating hole 13 on workpiece 1, play the effect to workpiece 1 radial location, and straight pin 23 is interference fit with the locating hole 13 of workpiece 1, after machining, by gas hole 24, workpiece 1 is blown out, workpiece 1 is convenient to take off from straight pin 23, positioning cap 3 is with internal thread, with car hole 31 on the end face 32 of positioning cap 3, positioning cap 3 to be coordinated with the described thread segment of cylinder 21 by described internal thread and carries out axial location to workpiece 1, adds man-hour, is machined by the cylindrical of the cylinder 12 of the 31 pairs of workpiece 1 in car hole.
Using method of the present invention is as follows:
The first step, by the gripping section clamping of locating dowel 2 on the chuck of lathe;
Second step, is loaded on workpiece 1 in square groove 22;
3rd step, is filled to positioning cap 3 on the thread segment of locating dowel 2;
4th step, is machined by the cylindrical of the cylinder 12 of the 31 pairs of workpiece 1 in car hole.
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.
