Working machinery having separation plate

Abstract

Provided is a working machine with separating plate which can be placed tightly while opened. The opening can be made big enough for various operation to the machining unit by opening the separating plate. The working machine has a machining unit in the front, and separating plates (40A, 40B) for separating machining areas (S1A, S1B) as the peripheral spaces of the machining unit and the upper space (S2). The separating plates can be switched freely on the front position (P1) and the rear position (P2), while separating on the front position and not separating on the second position out the machining areas and upper space. The working machine is further equipped with a separating plate supporting mechanism (70) which is in oblique pose while the separating plate is on the front position and in level pose while the separating plate is on the rear position.

Description

[0001] technology area [0002] The present invention relates to a machine tool provided with a partition plate for partitioning a processing area and a space above it. Background technique [0003] In a working machine such as a lathe, an openable partition plate is provided to partition a machining area from a space above it (for example, Patent Document 1). The partition plate is used to prevent chips and the like from flying out of the processing area, and is closed during processing, and opened when preparing the machine tools in the processing area, performing maintenance, cleaning, etc. in the processing area. As shown in the working machine disclosed in Patent Document 1, conventional partition plates are installed horizontally. In addition, Patent Document 2 discloses a structure in which a door that partitions a processing area from a space in front thereof is provided so as to be inclined so as to be located toward the rear as it goes toward the upper end side. ...

Problems solved by technology

In addition, when a mechanism that opens and closes by sliding in a direction inclined along the partition plate is used, since the position of the partition plate in the opened state by sliding backward is higher than that in the closed state, the vertical dimension of the machine becomes larger.

In particular, when a loader for supplying and discharging workpieces to the processing machine is provided above the main body of the machine tool, the loader must be placed at a higher position in order to avoid interference with the partition plate in the open position. On the other hand, the upper and lower dimensions of the machine are further increased, and the lifting stroke of the loader must be increased
