example 1

[0051] Machine tool used: Pietro Carnaghi (Pietro Carnaghi) 1.6m vertical compound turning and milling machining center.

[0052] Scope of application: medium and large parts with a slewing diameter > 1600m, a clamping height > 170mm, and asymmetrical clamping types.

[0053] Processed parts: fixed planet carrier. Fixed planet carrier structure such as Figure 3a and 3b As shown, the rotation diameter of the fixed planet carrier is 1760mm, and the minimum clamping rotation diameter is 1920mm, which is far beyond the working range of the workbench of 1600mm; The connection beam at the place), it is impossible to achieve symmetrical clamping; the coaxiality and position of the parts are required to be high, and there are many processing positions for the hole type, so it is not suitable for repeated clamping.

[0054] Tooling process for fixing the planet carrier:

[0068] Machine tool used: Pietro Carnaghi (Pietro Carnaghi) 1.6m vertical compound turning and milling machining center.

[0069] Scope of application: medium and large parts with a slewing diameter > 1600m, a clamping height > 170mm, and asymmetrical clamping types.

[0070] Machining parts: input planet carrier. Fixed planet carrier structure such as Figure 6a and 6b As shown, the height of the input planet carrier is relatively high, so the clamping height must meet the processing force requirements and should not be too low; Figure 6a As shown, the upper side of the input planet carrier connection (the lower side of the input planet carrier, the far end of the planetary hole) has a non-rotating design, and the theoretical clamping position is the casting surface, which cannot achieve symmetrical clamping, and cannot be used as a secondary clamping The benchmark; the coaxiality and position of the parts have higher requirements, such as Figure 6b The flange faces on ...

Abstract

The invention relates to the technical field of vertical composite turning and milling, in particular to a special fixture for a vertical composite machining center. The tooling fixture includes a rotary tray 2, a claw high support 3 and several bolts and nuts fixing parts, as well as ring pad iron, a central fixed plate of a ring structure, a contour pad, and a pressure plate. The diameter of the circle is smaller than the rotary limit range of the rotary table of the vertical compound machining center, and the high-position support of the jaws is a weldment, which is used to increase the clamping position of the chuck jaws. The present invention can maximize the processing range of the workbench of the vertical composite machining center without affecting the machining accuracy; moreover, it can simulate the clamping method of the workbench, so that the clamping method is not only limited to the modes that the workbench itself can provide, but also What matters is diversity. The invention can be widely popularized in the fields of machine tool processing and the like.

In terms of efficiency, some parts need repeated clamping and processing to complete, and some parts cannot be processed at all because they exceed the processing range; in terms of accuracy, errors caused by repeated clamping are undoubtedly to be avoided to ensure processing accuracy , the processing of multiple steps should be completed with the least number of clamping times, the purp...
