Abstract
The utility model discloses a universal joint yoke boring and milling head with 90 degree extension arm for boring and milling machines, comprising an extension arm cylinder, an intermediate driving shaft and a milling cutter spindle. The utility model is characterized in that the front end of the extension arm cylinder is fixed with a box body of a support head, and the intermediate driving shaft is arranged inside the extension arm cylinder and is supported by the method that the end parts of the front side and the back side are sheathed with bearings. The front part of the intermediate driving shaft penetrates the inner of the box body of a support head, and the front end is provided with a bevel wheel. The milling cutter spindle is arranged inside the box body of the support head and is arranged with the intermediate driving shaft in 90 degrees. One end of the milling cutter spindle penetrates out of the box body of a support head, and the penetrating end is provided with a discal cutter. The milling cutter spindle is supported by the bearings sheathed on the end parts of the both sides of the milling cutter spindle. The milling cutter spindle is provided with a bevel wheel which is engaged with the bevel wheel installed on the front end of the extension arm. The utility model can become the special process tool which can process the wedge sliding surface of the support device of the upper part of the converter body with 250 ton steel, and can carry out the milling process to the four wedge sliding surfaces of two converters with 250 ton steel, which can reach and be superior to the design requirement.
Description
(1) technical field
The utility model relates to a kind of boring and milling machine, especially relates to a kind of boring and milling machine 90 ° of universal boring and milling head outer of extension arm.
(2) background technology
It is more smooth that existing 90 ° of universal boring and milling head outer do not have the processing of blocking outer surface to workpiece, but the workpiece complicated to structure adds man-hour, because the particularity of Workpiece structure, be difficult to reach processing request, for example, 250 tons of converter body upper support device chock sliding surfaces are at a high 660mm, wide 410mm, process in the square hole of length 3900mm, add and in above-mentioned hole, to carry out Milling Process man-hour the chock sliding surface, chock sliding surface width is 300mm, working depth is 0.5mm-5mm, length is 3900mm (the middle 885mm that is interrupted), the machined surface that also to can be considered two length be 1507.5mm, the depth of parallelism of machined surface requires less than 0.3mm, desired value is 0.1mm, surface roughness is Ra=3.2 μ m, and the such machining accuracy and the range of work are processed at all with existing special-purpose boring and milling head outer and can't be finished processing tasks.
(3) summary of the invention
In order to make existing special-purpose boring and milling head outer can be suitable for difficult processing structure, reach satisfied machining accuracy, the utility model provides a kind of boring and milling machine 90 ° of universal boring and milling head outer of extension arm, this extension arm can be installed on the existing floor-type milling ﹠ boring machine, and is combined into two 90 ° of universal boring and milling head outer with 90 ° of universal boring and milling head outer on the existing floor-type milling ﹠ boring machine.
The technical scheme that adopts is:
