Problems solved by technology

The inclination of the front end of the ram differs depending on the load acting on the front end of the ram (the presence or absence of accessories, the type), so when the displacement of the front end of the ram is corrected first, the inclination of the front end of the ram becomes larger, and an inclination occurs on the main shaft, thereby There is a problem of height difference at the connection part of the processed surface

Abstract

The present invention provides a ram deflection correcting device and a correcting method capable of simultaneously correcting the displacement and inclination of the front end of the ram. Therefore, in the ram deflection correction device for correcting the deflection of the ram (15) of the machine tool supported by the saddle and capable of moving in the horizontal direction (H), there is a first tie rod (21) along The horizontal direction (H) is set at a position above the center line (L) of the ram (5), and the pulling force (F1) that pulls the front end of the ram (15) inward is applied; the second pull rod (22 ), which is set in the horizontal direction (H) above the center line (L) of the ram (15), and applies a pulling force (F2), which will be larger than the first pull rod (21 ) is pulled inward from the position of the front end close to the inner side.

Description

technical field [0001] The present invention relates to a ram deflection correcting device and correcting method in horizontal machine tools and the like. Background technique [0002] Figure 7 The schematic structure of the existing horizontal machine tool is shown in . In the horizontal machine tool 50 , a bed 51 is provided with a column base 52 movable in the horizontal direction (for convenience, referred to as the front-rear direction), and a column 53 is erected on the column base 52 . One side of the column 53 is supported with a saddle 54 capable of moving in the vertical direction (for convenience, referred to as the up and down direction). .) Moving ram 55. The ram 55 has a main shaft, and the workpiece to be processed is processed by a tool attached to the front end of the main shaft. When processing, desired processing is performed while moving the column base 52 , the saddle 54 , and the ram 55 . At this time, the ram 55 is deflected D along with the movem...
