Abstract

The invention relates to a threaded shaft turning positioning device comprising a locating sleeve. The threaded shaft turning positioning device is characterized in that the locating sleeve comprises a clamping section and a tapered section, wherein the clamping section is provided with an internal thread, and the tapered excircle of the tapered section is provided with an external thread; elongated holes are arranged at the periphery between the clamping section and the tapered section, connection seams are arranged from the bottoms of the elongated holes to the end face of the tapered section, the width of each connection seam is from the periphery of the locating sleeve to the inner wall of a center hole of the locating sleeve, and the connection seams divide the locating sleeve into four parts from the bottoms of the elongated holes; and clamping nuts are arranged on the excircle of the tapered section 4. The threaded shaft turning positioning device disclosed by the invention is simple in structure, convenient to operate and high in positioning machining precision.

Description

The thread spindle turning positioning device
Technical field
The present invention relates to technical field of tooling clamps, relate in particular to a kind of positioning tool to machining with externally threaded axle.
Background technology
Thread spindle refers to the externally threaded axle of excircle band, axle is being carried out face work or turning adds man-hour, usually axle clamp can be held on the scroll chuck of lathe, but for thread spindle, and the external screw thread that this kind method of clamping can the double thread axle causes major injury.
Summary of the invention
The present invention is directed to the problems referred to above of the prior art, a kind of thread spindle turning positioning device 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:
The thread spindle turning positioning device comprises positioning sleeve, it is characterized in that: described positioning sleeve comprises gripping section and conical section, and gripping section is with internal thread, on the conical external circle of conical section with external screw thread; On the circumference between gripping section and the conical section with elongated hole, the bottom of elongated hole to the end face of conical section has connecting sewing, the inwall of the centre bore of the width of connecting sewing from the periphery of described positioning sleeve to described positioning sleeve, connecting sewing is divided into four parts from the bottom of elongated hole with described positioning sleeve; On the cylindrical of taper 4 binding nut is installed.
The invention has the advantages that: internal thread is set to the thread segment cooperation location of the thread spindle of workpiece on the gripping section of positioning sleeve, at positioning sleeve conical section is set, and on the cylindrical of conical section external screw thread is set, and open connecting sewing in conical section to its bottom, make positioning sleeve have certain elasticity, cooperate with the cylindrical of conical section by binding nut, can regulate the clamping degree of double thread axle; 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 front view of positioning sleeve of the present invention.
Fig. 2 is that Fig. 1 is the A-A cutaway view.
Fig. 3 is the top view of Fig. 1.
Fig. 4 is the B-B cutaway view of Fig. 3.
Fig. 5 is that the master of the present invention when workpiece is positioned looks cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
To shown in Figure 5, the present invention includes positioning sleeve such as Fig. 1, described positioning sleeve comprises gripping section 1 and conical section 4, and gripping section 1 is with internal thread, can cooperate in the external screw thread of the thread segment 7 of thread spindle, on the conical external circle of conical section 4 with external screw thread; On the circumference between gripping section 1 and the conical section 4 with elongated hole 2, the bottom of elongated hole 2 to the end face of conical section 4 has connecting sewing 3, the inwall of the centre bore 5 of the width of connecting sewing 3 from the periphery of described positioning sleeve to described positioning sleeve, connecting sewing 3 is divided into four parts from the bottom of elongated hole 2 with described positioning sleeve, so that the cylindrical of described positioning sleeve has certain elasticity; Binding nut 6 is installed on the cylindrical of conical section 4, and binding nut 6 cooperates with the external screw thread of conical section 4, when rotation clamps screw thread 6, can make to be processed section 8 of conical section 4 double thread axles to clamp, and carries out the processing of car end or turning.
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.
