Description
Technical field
The utility model relates to endoporus and internal thread machining technical field, especially relates to a kind of endoporus and internal thread machining lathe.
Background technology
In the industry such as Aero-Space, modern machinery and equipment, automobile and instrument, thread part is very important fastening connection piece, and its consumption is very large.There is data to show, in the parts of modern machines, have the part of screw thread process to account for more than 60%.
In machining, the workload of about 30% is the processing in various hole, and the processing of internal thread account for 14% of all hole machined workloads.Because internal thread machining belongs to semi-enclosed multiple cut, processing conditions is poor, makes the processing of internal thread have certain difficulty.
Current, general employing hand tapping and machine tool tapping two kinds of manufacturing process.
Hand tapping can be special equipment, also can carry out in the plant equipment such as upright drill.On drilling machine during hand tapping, the gyration of screw tap is realized by motor drive transmission device, and feed motion is by manually realizing.An its energy part is delivered on screw tap by motor by transmission mechanism, and a part is provided by people.Its production efficiency is lower, wayward, and the crudy of the experience of workman to workpiece has considerable influence.
Machine tool tapping refers to the machining screw on workpiece with forming tool or grinding tool, and main method has milling, turning, mantle fiber, tapping, grinding, grinding and whirling etc.During by motor-driven method machining screw, workpiece is often gone around, and the driving-chain of lathe ensures that milling cutter, lathe tool or emery wheel are along workpiece spindle to moving a helical pitch accurately and uniformly.
The method of machining internal thread is a lot, but in general, the internal thread segment processed can not be oversize, especially in the process of turnery processing internal thread, the length of cutter needs the length with internal thread segment increase and increase, and long knife bar can produce vibration in process, causes clamping unstable, easily cause the damage of cutter, and affect the machining accuracy of screw thread; Moreover longer pipe fitting is more difficult when the material returned; 3rd, tapping is if a tapping is to size, because of the too large not easily chip removal of cutting depth, so cutting force is very large, the intensity of screw tap is difficult to meet, and screw tap loss is very large, and the iron filings of huge cutting force and accumulation are easy to damage the thread processed, cause the imperfect generation waste product of tooth form; And if adopt multiple tracks tap tapping, greatly can reduce working (machining) efficiency, increase processing cost.
But, along with the development of advanced material and advanced technologies, there is increasing strange shape part, especially needed the long pipe fittings of machining internal thread.Existing internal thread machining mode, when processing the internal thread of this long pipe fittings, be difficult to ensure its machining accuracy, and processing cost is higher.
Utility model content
