Abstract
The invention discloses a spline machining method. The spline machining method includes the steps that an internal thread spline machining tool is used for machining an internal thread spline; the internal thread spline machining tool comprises a cutter rod with an external thread section and a top cover, the cutter rod is provided with a protruding part and sleeved with a spring, a power cylinder is arranged at the front end of the top cover, and a quartz sand layer is arranged on the inner surface of the internal thread section. The machining process includes the following steps that A, internal thread rough machining is carried out on a long cylinder, then fine machining is carried out through the internal thread spline machining tool, the cutter rod extends into the cylinder, the tail end of the cutter rod is fixed, the top cover is installed on the cylinder, and the top cover is connected with the power cylinder; B, the cylinder rolls on the external thread section of the cutter rod in a reciprocating mode under the action of the power cylinder and the spring, the quartz sand layer on the external thread section grinds an internal thread of the cylinder to finish fine machining of the internal thread; C, line segmentation is carried out on the cylinder obtained from the step B, so that multiple splines are obtained. The spline machining method resolves the problems that an existing internal thread spline machining method is complex and high in production cost.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of method for processing internal thread spline.
Background technology
In the technical field of machine-building, often can use a kind of internal thread spline, i.e. the external screw thread shape that radially rotates of the key of splined interior.Existing internal thread spline is generally use lathe to pull out in annulus with broaching tool, and difficulty of processing is comparatively large, and precision is satisfied to be protected, and processing cost is higher.Thus need to design a kind of result simple, easy to operate, the instrument that power consumption of polymer processing low cost is low and method, to improve the processing of internal thread spline.
Summary of the invention
Problem to be solved by this invention is to provide a kind of spline processing method, to solve existing internal thread spline processed complex, the problem that production cost is high.
In order to solve the problem, technical scheme of the present invention is: this spline processing method comprises a kind of internal thread spline machining tool machining internal thread spline of use; Described internal thread spline machining tool comprises the knife bar with external thread section, described knife bar is provided with one week protruding lug boss in the front end of described external thread section, described knife bar is equipped with spring in the front end sleeve of described lug boss, the front end of described knife bar is provided with the top cover for withstanding internal thread tube piece to be processed outside described spring, described top cover front end is provided with the power cylinder driving described top cover to move reciprocatingly along described knife bar axis direction, and described internal thread segment inner surface is provided with quartz sand layer;
Its processing comprises the following steps:
A, first internal thread roughing is carried out to microscler cylinder, re-use described internal thread spline machining tool and carry out fine finishining, the knife bar of described internal thread spline machining tool is stretched into cylinder, and described knife bar end is fixed, described cylinder installs top cover, and the front end of described top cover connects power cylinder;
B, start described power cylinder, described power cylinder stretches out and compresses described top cover and described cylinder, the internal thread segment of described cylinder relative motion spin friction on described knife bar external thread section, when described spring is compressed into extreme position, described power cylinder retraction, described power cylinder retraction force and described spring drive described top cover and described cylinder move along power cylinder direction and rotate, so repeatedly, under the effect of described power cylinder and described spring, described cylinder moves reciprocatingly and rotates, reciprocating rolling on described knife bar external thread section, the internal thread of cylinder described in quartz sand layer grinding on described knife bar external thread section, complete the fine finishining of internal thread,
C, the cylinder obtained by step B carry out Linear cut, are multistage by described cylinder transversely cutting, more than one piece internal thread spline.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
This spline processing method adopts a kind of special instrument, by arranging lug boss and spring with on the knife bar of external thread section, the internal thread tube piece of band processing installs top cover, before top cover, establish power cylinder, utilize the power of spring restoring force and power cylinder, make the external thread section of knife bar and the inside of internal thread tube piece produce crankmotion, with evenly quick and laborsaving the grinding completing the internal thread of internal thread spline, structure is simple, and easy to operate, difficulty of processing reduces greatly; This method adopts Linear cut that cylinder to be processed is cut into multiple internal thread spline again, is ensureing the technical of machining accuracy, simplified processing process, is accelerating working (machining) efficiency, cut down finished cost.
