Description

Elbow stand vertical and horizontal dual-purpose five-surface machining center

Technical Field

The utility model relates to a digit control machine tool, machining center technical field relate to an elbow stand is dual-purpose five-face machining center of crouching immediately.

Background

The traditional boring and milling machining center has a vertical and horizontal division; for a workpiece in clamping, the traditional vertical machining center can only machine the top surface (horizontal surface) of the workpiece, and the traditional horizontal machining center can only machine the periphery (all the surfaces around) of the workpiece. For a workpiece needing to be machined on five surfaces, the traditional machining process method is that a top plane of the workpiece is machined vertically, and the periphery of the workpiece is machined by a horizontal machining center. For a factory with only a vertical machining center, when a five-surface workpiece is machined, the five-surface machining can be realized only by adopting a mode of clamping for multiple times (5 times). For a factory which only has a horizontal machining center, a five-surface workpiece is machined, the five-surface machining program can be machined and finished only by clamping twice, the workpiece is clamped for multiple times, the positioning error is large, time and labor are wasted, the workpiece turnover time is long, the production efficiency is low, the manufacturing cost is high, and the traditional machining center cannot meet the market demand due to the fact that the five-surface machining demand is larger and larger. In recent years, five-side machining centers of various versions are available on the market. The two five-surface processing centers have huge structures and large occupied area, are extremely inconvenient for workpiece installation and operation, and have relatively high manufacturing cost and use cost; in addition, the five-surface machining center has two single-column type five-surface machining centers, the two five-surface machining centers take a vertical machining center as a basic type, a vertical spindle box and a horizontal spindle box share one column, a rotary worktable (or an indexing worktable) is additionally arranged on the table top of a worktable of the vertical machining center to form the five-surface machining center, and the two single-column machining centers are only distinguished; one is to add a pair of guide rail pairs on the side of the original upright post, and hang a horizontal main spindle box on the upper side of the guide rail pairs; the other type is a five-machine machining center which utilizes the original upright post guide rail pair, a horizontal main shaft box is arranged on the front surface of the guide rail pair, and the vertical and horizontal main shaft boxes share the upright post guide rail pair; the side-hung five-face machining center is most typically a so-called single-upright vertical-horizontal composite multi-face machining center, the most typical one of which is a vertical-horizontal dual-purpose machining center, the most typical one of which is a novel patent application published under the publication No. CN 208196162U, the most typical one of which is a vertical-horizontal dual-purpose machining center, the most typical one of which is a patent application published under the publication No. CN 109807381A, and the two five-face machining centers derived by taking the vertical machining center as a base have the common defects that the overhang of the vertical main shaft box is lengthened by one section, and the distances from the end face of the horizontal main shaft to the guide face of the upright post are the same in length, so; the excessive unbalance loading moment and the overhung moment not only can influence the stability of the main shaft box in motion, but also have obvious influence on the service life of a main shaft bearing and the surface roughness of a machined zero surface, and particularly have difficulty in avoiding the chattering of the main shaft box in high-speed, high-precision and heavy-load operation. In particular, when heavy cutting is carried out, an overlong overhanging spindle box can generate irregular vibration, so that a cutter is damaged quickly, and can be disassembled and broken, so that a machine tool cannot work normally, besides the common defect, the invention patent application publication No. CN 109807381A is a vertical and horizontal dual-purpose machining center, and has two problems, one is the processing, assembling and adjusting difficulty caused by the fact that a vertical column needs to be increased and the vertical column guide rail grows, and the other is the congenital defect caused by the fact that the scheme itself is not well considered, so that the feasibility and practicability problems of the patent can be related, for example, the vertical and horizontal machine head (spindle box) shares a guide rail pair on the vertical column, before the vertical spindle box is put into a machined workpiece, the spindle box of the horizontal machining center must firstly be lowered to the lowest end of the vertical column guide rail to make the guide rail effective space out, when the vertical spindle box is put into machining, a cutter arranged on the high-speed rotating spindle head can throw chips generated in machining out at a high speed along with cutting fluid, splash around and scatter everywhere, and at the moment, the spindle taper hole of the horizontal spindle box at the lower end of the guide rail becomes a chip and cutting fluid accommodating hole and can be filled with the spindle taper hole instantly, most feasibly, the high-temperature chips thrown out at a high speed can directly hit the conical surface of the horizontal spindle taper hole sometimes, and spots and fusion points are generated to cause the direct scrapping of the spindle.
