Special tool fixture for vertical type combined machining center

Abstract

The invention relates to the technical field of vertical type combined turning-milling machining, in particular to a special tool fixture for a vertical type combined machining center. The tool fixture comprises a rotary tray 2, clamping jaw high-position supports 3, a plurality of bolt and nut fixing components, an annular sizing block, a center fixing disc of an annular structure, equal-height pads and pressing plates, wherein the rotary tray is of an annular structure, the diameter of the annular outer circle of the rotary tray is smaller than the rotary limit range of a rotary workbench ofthe vertical type combined machining center, and the clamping jaw high-position supports are weld assemblies and are used for heightening the clamping positions of chuck jaws. By means of the specialtool fixture for the vertical type combined machining center, the machining range of the workbench of the vertical type combined machining center can be widened to the maximum extent, and machining precision is not influenced; and in addition, a clamping method of the workbench can be simulated, clamping modes are not only limited to modes provided by the workbench, and more importantly, the clamping modes are diversified. The special tool fixture for the vertical type combined machining center can be widely popularized in the field of machining with machine tools and the like.

Description

technical field [0001] 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. Background technique [0002] At present, as far as the field of mechanical processing is concerned, in most cases the supporting facilities of the machine tool itself are very limited. Under the premise of no special requirements, the corresponding tooling matched with the machine tool is also the most basic, so in the process of processing, it can meet the processing needs. conditions are thus limited. 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...

[0002] At present, as far as the field of mechanical processing is concerned, in most cases the supporting facilities of the machine tool itself are very limited. Under the premise of no special requirements, the corresponding tooling matched with the machine tool is also the most basic, so in the process of processing, it can meet the processing needs. conditions are thus limited

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 purpose is to ensure the uniformity and consistency of the benchmark; in terms of cost, the price of customizing the corresponding tooling from the machine tool manufacturer is generally 4 to 5 times that of self-made, Imported equipment is even worse, and the types are limited. Its accuracy cannot be effectively guaranteed because it is out of reality and has not been surveyed and understood on the spot. Generally, it cannot be used directly. It needs to be calibrated or modified later, and even if it can be customized Procurement, but the customization cycle is long and unpredictable, which seriously affects the processing efficiency
