Description
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 vehicle thread spindle processing and positioning device is provided, it is simple in structure, and is easy and simple to handle, and the location machining accuracy is high, good economy performance.
The technical solution adopted in the present invention is as follows:
Vehicle thread spindle processing and positioning device comprises positioning sleeve, and described positioning sleeve comprises gripping section and clamp segment, and gripping section is with internal thread, on the cylindrical of clamp segment with external screw thread; On the circumference between gripping section and the clamp segment with elongated hole, the bottom of elongated hole to the end face of clamp segment 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 clamp segment binding nut is installed, the inner chamber of clamp segment is bellmouth, and chuck is installed in the bellmouth, and described chuck comprises taking over a business, and with centre bore, takes over a business the bottom with the intermediate plate that is separated from each other on taking over a business, and is the gap between the intermediate plate, and intermediate plate is bullet.
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 clamp segment is set, and on the cylindrical of clamp segment external screw thread is set, and open connecting sewing in clamp segment to its bottom, make positioning sleeve have certain elasticity, in the internal tapered hole of clamp segment, conical chuck is installed, cooperate with the cylindrical of clamp segment by binding nut, make chuck regulate the clamping degree of double thread axle, can carry out clamping and positioning to the thread spindle of different size by conical chuck; The present invention is simple in structure, and is easy and simple to handle, and the location machining accuracy is high, good economy performance.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
To shown in Figure 7, the present invention includes positioning sleeve such as Fig. 1, described positioning sleeve comprises gripping section 1 and clamp segment 4, and gripping section 1 is with internal thread, can cooperate with the external screw thread of the thread segment 12 of thread spindle, on the cylindrical of clamp segment 4 with external screw thread; On the circumference between gripping section 1 and the clamp segment 4 with elongated hole 2, the bottom of elongated hole 2 to the end face of clamp segment 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 10 is installed on the cylindrical of clamp segment 4, binding nut 10 cooperates with the external screw thread of clamp segment 4, the inner chamber of clamp segment 4 is bellmouth 11, in the bellmouth 11 chuck is installed, described chuck comprises taking over a business 6, take over a business on 6 with centre bore 9, taking over a business 6 bottoms with the intermediate plate 8 that is separated from each other, is gap 7 between the intermediate plate 8, and intermediate plate 8 is bullet, when rotating clamp jack panel 10, binding nut 10 withstands described chuck from the bottom surface of intermediate plate 8, and described chuck is moved upward along bellmouth 11, and intermediate plate 8 shrinks thereupon simultaneously, to be processed section 13 of the double thread axle clamps, and carries out the processing of car end or turning; Owing to having gap 7 between the intermediate plate 8 of described chuck, make chuck is had certain elasticity, can carry out clamping and positioning to the thread spindle of different size, improved range of application of the present invention, have higher economy.
Above description 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.
