Description

Tooth-shaped triple gear machining tool with angular relation

Technical Field

The utility model relates to the field of machining, concretely relates to profile of tooth has angle to relation trigeminy gear machining frock.

Background

With the development and progress of social technology, the structural characteristics that the tooth directions of the gear, the duplicate gear and the triple gear have angular relation requirements have been widely applied to special fields with directional positions, such as unmanned aerial vehicles, radar antennas and the like. Among them, the machining method of the single gear and the double gear having a certain angular relationship with a certain structure (square, straight edge, etc.) is common, and the machining method is mature. The processing method of angular relation between the tooth form of the triple gear and a certain structure (square, straight edge and the like) is less. The method for machining the triple gear according to the angular relation of the tooth profile of the double gear has the advantages of same principle, higher machining difficulty, high technical level required by operators, low qualified rate of machined parts and unstable quality of the machined parts.

As shown in fig. 8-9, the conventional gear machining tool includes a positioning tool body 01; a through hole 010 for the triple gear 02 to pass through is arranged in the middle of the positioning tool body 01 in a penetrating manner, and three cylindrical pins 011 are embedded at the periphery of the through hole 010 at the upper part; the positioning tool body 01 is further provided with fixing holes 012 on two opposite sides of the through hole 010; this location frock body 01 has still seted up a plurality of recesses 014 along circumference. The triple gear 02 includes a gear shaft 021, a first gear 022, a second gear 023, and a third gear 024. Before the gear machining tool for positioning and machining the gear with the angular position is used, the gear hobbing machining of the second gear 023 of the triple gear 02 is completed firstly, gear shaping machining can be performed if no gear hobbing equipment exists, but the gear shaping machining efficiency is low because the gear hobbing machining efficiency is high, and then the gear shaping machining is performed on the first gear 022 and the third gear 024 in gear manufacturing equipment (a gear shaping machine).

In the conventional gear machining tool, based on the tooth profile machined by the second gear 023, the tool is designed and the tooth profile of the second gear 023 is fixed in position by three cylindrical pins 011, two teeth (symmetrical to the cylindrical pins 011) are marked on the second gear 023, and a line 013 is marked at the position shown in the figure as a starting position for machining the first gear 022 and the third gear 024. After first gear 022 processing is accomplished, take off frock and triple gear 02, then install the frock, the triple tooth 02 of installation turns around in order to be ready to process third gear 024, and two teeth that second gear 023 has marked need be put in the position with processing first gear 022 when noting the installation of triple gear 02, and the initial position of processing is the same with processing first gear 022 position, and until third gear 024 processing is accomplished. According to the method, the triple gear 02 needs to be taken down and clamped for the second time, the efficiency of the processed triple gear 02 is low, the product percent of pass is low, and the quality is unstable. Because the machining of the second gear 023 in the triple gear 02 has machining errors, the errors are accumulated to enlarge the subsequent machining errors, which is good for machining the double gear but not suitable for machining the triple gear 02.

In view of the foregoing, there is a need for further improvements in the prior art.
