Description

Split type milling cutter saddle

Technical Field

The utility model relates to the technical field of machining, specifically be a split type milling cutter knife rest.

Background

The tool rest is a very important part of the numerical control lathe. According to the functions of the numerical control lathe, the number of the cutters which can be arranged on the tool rest is four, six, eight, ten, twelve, twenty and twenty-four, and some numerical control lathes can be provided with more cutters. The tool rest is generally in a rotary structure, and the tool is arranged on the tool rest along the circumferential direction and can be provided with a radial turning tool, an axial turning tool, a drill bit and a boring tool. The turning center can also be used for installing axial milling cutters and radial milling cutters. The tool post on the numerical control machine tool is an important part for placing the tool, and many tool posts also directly participate in cutting work, such as a square tool post on a horizontal lathe, a turret tool post of a turret lathe, a return pulley tool post of a return pulley type turret lathe, a turret tool post of an automatic lathe, a balance tool post and the like. These tool holders, which both hold the tools and are involved directly in the cutting, are subjected to extreme cutting forces, so that they often become a weak link in the process system. With the development of automation technology, the tool rest of the machine tool has changed, especially the numerical control machine tool adopts an automatic tool rest of electrohydraulic transposition, and some machine tools also use two rotary cutter heads. The machining center further adopts a tool magazine and a tool changing manipulator, the functions of storing tools in large capacity and automatically exchanging tools are achieved, the number of the tools placed in the tool magazine is dozens of tools to hundreds of tools, and the time for automatically exchanging tools is reduced from tens of seconds to seconds or even fractions of seconds. The numerical control lathe can be provided with two tool rests, a special tool rest is developed by a lathe manufacturer, and the used tool shank is also special. The advantage of such a blade holder is that it is inexpensive to manufacture, but lacks versatility. The universal tool rest is produced according to a certain universal standard, and a numerical control lathe manufacturer can select and configure the universal tool rest according to the functional requirements of the numerical control lathe. The development trend of the numerical control tool rest is that along with the development of a numerical control lathe, the numerical control tool rest begins to develop towards the directions of rapid tool changing, electro-hydraulic combined driving and servo driving. The domestic numerical control tool rest mainly adopts electric operation and is divided into a vertical type and a horizontal type. The vertical tool rest has two forms of four stations and six stations, and is mainly used for simple numerically controlled lathes, and the horizontal tool rest has eight stations, ten stations, twelve stations and the like, can rotate in the positive direction and the negative direction, selects a tool nearby, and is used for full-function numerically controlled lathes. In addition, the horizontal tool rest also comprises a hydraulic tool rest and a servo drive tool rest. And the milling cutter saddle in the existing market, it is integral more, it is inconvenient when dismantling the installation, reduce work efficiency, delay the working process, give people and bring inconvenience, consequently need improve.
