Problems solved by technology

When the connecting shaft collides with the edge of the through hole of the connecting plate and slides against the edge of the through hole, it will be worn, and the gap between the connecting shaft and the connecting plate will expand.
When the gap between the connecting shaft and the connecting plate expands, each cover will move irregularly, and malfunctions, damages, etc. may occur

Embodiment Construction

[0017] Next, the machine tool of the present invention will be described based on the drawings. The front-back direction, the left-right direction, and the up-down direction used in the following description are as shown in each drawing. figure 1 It is a three-dimensional view of the appearance of the machine tool.

[0018] The machine tool has a base 1, an XY-axis moving device 2, a table 3, a Z-axis moving device 4, a tool magazine 5, and a control device 6 for controlling the operation of the machine tool. The X-axis direction corresponds to the left-right direction, the Y-axis direction corresponds to the front-rear direction, and the Z-axis direction corresponds to the up-down direction.

[0019] The XY axis moving device 2 is disposed on the upper surface of the base 1 . The workbench 3 is arranged on the XY axis moving device 2 . The XY axis moving device 2 has a ball screw mechanism. The table 3 can move in the left-right direction and the front-rear direction unde...

Abstract

The present invention provides a telescopic shield and a machine tool having the telescoping shield. One connecting plate and the other connecting plate have through holes in an intersecting portion. A connecting shaft runs through the through holes. The connecting shaft has a head portion, an opposite portion and an external thread portion, and the head portion, the opposite portion and the external thread portion are connected in the axial direction. The connecting shaft has a plurality of grooves arranged in the vertical direction on the peripheral surface of the opposite portion. Each groove extends in the circumferential direction of the opposite portion and entirely around the opposite portion. The grooves are located in portions, opposite to each edge portion of the through holes, of the opposite portion. The grooves can prevent the edge of the through holes from colliding with the connecting shaft, and the connecting shaft slides with respect to the edge of the through holes, thereby reducing the wear of the connecting shaft.

Description

technical field [0001] The invention relates to a telescoping cover and a machine tool with the telescoping cover. Background technique [0002] A machine tool is capable of holding a workpiece on a table and performing various processes such as milling and tapping on the workpiece using a tool mounted on a spindle. When machining a workpiece, the table moves relative to the installation surface of the machine tool in a direction parallel to the installation surface of the machine tool by the moving device. Chips from the workpiece, etc. fall and scatter from the table toward the moving device, causing the moving device to malfunction. [0003] In order to prevent the above failures, sometimes a workbench with a telescoping cover is used. Japanese Patent Laid-Open Publication No. 010479 of 1999 discloses a telescopic shield. The telescopic cover covers the mobile device, and the entire cover can be expanded and contracted along with the movement of the table, thereby prev...
