Description
Technical Field
The invention relates to a threading tool for processing external threads of a sleeve by using a round die threading on a lathe, a boring machine and a drilling machine, in particular to a multi-specification round die threading quick-change tool for threading serial specifications of external threads. The threading tool can be used for threading screws of various specifications and models, can control the effective length of threading threads, and ensures the stability and reliability of thread threading.
Background
In the processing machinery industry, various shafts or rods are often required to be threaded. The external thread is a workpiece commonly used in machining industry, and the threading die is a thread machining tool for machining or correcting the external thread. The screw die is equivalent to a nut with high hardness, a plurality of chip removal holes are formed around the screw hole, and cutting cones are generally ground at two ends of the screw hole. The dies are classified into round dies, square dies, hexagonal dies and tubular dies according to their shapes and uses. The round die is the most widely used round die, and the specification range is M0.25-M68 mm. The square die is mainly used for processing external threads of a fixed lathe, the hexagonal die is rare compared with the square die, and the hexagonal die and the square die have no fixed national standards. The threading die can be installed in a threading die wrench for manually machining threads, and also can be installed in a threading die frame for use on a machine tool. Traditional die sleeve preparation is complicated, uses the material many, causes the price also relatively more expensive like this, directly overlaps the vertebra handle of vertebra handle chuck in the tailstock taper hole in the use, shakes out the tailstock, until being close the work piece, opens the lathe at a slow speed, and the die rotates with the work piece together, lets the work piece wind into with the screw tap by oneself in rotatory. Meanwhile, in the machining process, the phenomenon that the conical part of the clamp slips with the wall of the tailstock sleeve hole is easily caused, so that the abrasion of the tailstock sleeve hole is aggravated, the tooth form of the thread is damaged, and the tooth decay phenomenon is caused. The processing mode at the present stage is that a rotary chuck on a lathe is generally used for clamping a workpiece, a threading die is fixed in a ring sleeve of a threading chuck of the threading die, the threading die is fixed through a fixing screw, a workpiece is kept vertical to the threading die on the same horizontal line, the chuck drives the workpiece to rotate, so that the threading die is driven to rotate relatively, manual threading is carried out on external threads with single specifications, the threading die moves straightly along the direction of a main shaft of a machine tool, the workpiece is cut by rotating threads or extrusion cutting, and when the threading die rotates for 1/2-1 week, the threading die is inverted for 1/4 weeks until the threading is finished. The traditional processing method for threading the dies by hand has the defects that the dies are held by hands, the operation is difficult, and the threading speed is slow. The manual holding of the screw die handle exerts uneven force, the machined workpiece is easy to shake, the machined thread tooth profile is easy to generate the conditions of tooth decay, tooth damage, thread deformation and the like, the quality of the machined external thread is not high, and the machining stability and reliability are difficult to ensure. Secondly, the operation safety performance is low, and the swing of the screw die can occur to cause safety accidents. Aiming at the screw workpieces with different specifications of external threads and non-standard thread pitches and with thick threads and thin threads, the screw workpieces with the existing specifications need to be taken down, and the screw dies with the corresponding specifications are continuously replaced. The threading die is frequently replaced, so that the clamping and debugging are troublesome, time and labor are wasted, the machining efficiency is low, the production difficulty is caused by the machining difficulty, and the field production requirement is hardly met.
