Abstract
The invention discloses a spline machining tool which comprises a cutter rod with an outer-threaded section. The cutter rod is provided with a circle of protrusion at the front end of the outer-threaded section. A spring sleeves the cutter rod at the front end of the protrusion. A top cover pushing against a to-be-machined inner-threaded pipe fitting is disposed at the front end of the cutter rod and outside the spring. A power cylinder for driving the top cover to reciprocate along the axis of the cutter rod is disposed at the front end of the top cover. An inner-threaded section is provided with quartz sand layer on the inner surface. Compared with the prior art, the spline machining tool has the advantage that the problems that an existing inner-threaded spline is complex to machine and high in production cost are solved.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of instrument 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, 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 machining tool, 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 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.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
This spline machining tool is 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, power cylinder is established before top cover, 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, easy to operate, difficulty of processing reduces greatly, and processing cost also reduces.
Accompanying drawing explanation
Fig. 1 is the front view of the embodiment of the present invention;
Fig. 2 is the A place enlarged drawing in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
Spline machining tool as shown in Figure 1 and Figure 2, it comprises the knife bar 7 with external thread section 4, knife bar 7 is provided with one week protruding lug boss 3 in the front end of external thread section 4, knife bar 7 is equipped with spring 2 in the front end sleeve of lug boss 3, and the front end of knife bar 7 is provided with the top cover 1 for withstanding internal thread tube piece 5 to be processed outside spring 2.Top cover 1 front end is provided with the power cylinder driving top cover 1 to move reciprocatingly along knife bar 7 axis direction, and power cylinder is here cylinder 8.External thread section 4 outer surface is provided with quartz sand layer 6.
During use, knife bar 7 end is fixed, screw thread on top cover 1 is connected fastening with cylinder 5 external screw-thread to be processed, top cover 1 connects the clutch end of cylinder 8, and under the effect of power cylinder and spring 2, cylinder 5 moves reciprocatingly and rotates, reciprocating rolling on knife bar 7 external thread section 4, the internal thread of the quartz sand layer 6 grinding cylinder 5 on external thread section 4, completes the processing of internal thread, with Linear cut, cylinder 5 to be processed can be cut to multiple spline afterwards.
