Abstract

The invention relates to a locating clamp for turning an excircle with high accuracy. The locating clamp comprises a locating column and a locating cap, wherein a column body of the locating column is divided into a clamping section and a thread section; a square groove is formed in the end face of the thread section; a cylindrical pin and a gas hole are arranged inside the square groove; an inner thread is arranged on the locating cap; a turning hole is formed in the end face of the locating cap, and the locating cap is matched with the thread section through the inner thread. The locating clamp is simple in structure, simple and convenient to operate, and high in locating and machining accuracy.

Description

High accuracy turning positioning fixture
Technical field
The present invention relates to technical field of tooling clamps, relate in particular to the positioner that a kind of precision workpiece carries out finish turning processing.
Background technology
Workpiece 1 as shown in Figure 1, workpiece 1 comprises square floor 11, on the base plate 11 vertically with cylinder 12, cylinder 12 has locating hole 13, now need as requested the cylindrical of cylinder 12 is carried out fine finishining, be difficult for adopting modes such as milling processing for this class formation workpiece 1, Vehicle Processing is usually used in the cylinder cylindrical is carried out thick finish turning processing, but the size of workpiece 1 is less and with square floor 1, be difficult for workpiece 1 is carried out direct clamping, need special tooling, just easily guarantee the fine finishining precision of workpiece 1 cylinder 12 cylindricals.
Summary of the invention
The present invention is directed to the problems referred to above of the prior art, a kind of high accuracy turning positioning fixture is provided, it is simple in structure, and is easy and simple to handle, and the location machining accuracy is high.
The technical solution adopted in the present invention is as follows:
High accuracy turning positioning fixture comprises locating dowel and positioning cap, and the cylinder of locating dowel is divided into gripping section and thread segment, and with square groove, square groove is interior with straight pin and gas hole on the end face of described thread segment; Positioning cap is with internal thread, and with the car hole, positioning cap cooperates with described thread segment by described internal thread on the end face of positioning cap.
The invention has the advantages that: on the locating dowel upper surface, in setting party's connected in star and the groove straight pin is set, workpiece is accurately located, attacked external screw thread on the cylindrical of locating dowel simultaneously, with the screw-internal thread fit of positioning cap, take workpiece by force and carry out axial location; The present invention is simple in structure, and is easy and simple to handle, and the location machining accuracy is high.
Description of drawings
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 use state diagram of the present invention.
The specific embodiment
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 used for cylinder 21 is clamped to the chuck of lathe, on the end face of described thread segment with square groove 22, square groove 22 is interior with straight pin 23 and gas hole 24, groove 22 can cooperate with the base plate 11 of workpiece 1, straight pin 23 cooperates with locating hole 13 on the workpiece 1, play the effect to workpiece 1 radial location, and the locating hole 13 of straight pin 23 and workpiece 1 is interference fit, after machining, can workpiece 1 be blown out by gas hole 24, be convenient to workpiece 1 is taken off from straight pin 23; Positioning cap 3 is with internal thread, on the end face 32 of positioning cap 3 with car hole 31, positioning cap 3 cooperates with the described thread segment of cylinder 21 by described internal thread workpiece 1 is carried out axial location, adds man-hour, and the cylindrical of the cylinder 12 by the 31 pairs of workpiece 1 in car hole machines.
More than describing is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
