Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a tool magazine mounting structure in a machining center.

[0002]

[Prior art]

 Conventionally, a machining center mainly uses rotating tools, has an automatic tool change function, and performs many types of machining without replacing work pieces, which is extremely convenient and has excellent work efficiency. It is a thing.

However, also in this machining center, when the tool mounted in the tool magazine is worn out due to use and needs to be replaced with a new one, or when the tool is damaged, it is necessary to manually replace it. There is.

[0004] Usually, there are a tool magazine that horizontally turns and a tool that vertically rotates like a ferris wheel in an annular vertical direction. In both cases, the tool magazine is above the moving space of the moving column of the machining center. It is installed on the support base that is erected in the main body bed, and is located inside the main body bed. The height of the machining center is about 2 m, and I could not reach it, I got on the step, etc., and even if I bent my upper body to the tool magazine side and approached it and pulled out the tool for replacement, the work was extremely complicated.

As a known document of a conventional example, in a machining center disclosed in Japanese Utility Model Laid-Open No. 1-149232, a frame 3 is fixed on a bed 1, and a tool magazine 21 is mounted on the frame. However, the tool magazine is provided within the width of the bed 1 parallel to the longitudinal direction of the bed.

Further, the machining center described in Japanese Utility Model Publication No. 7-30260 is characterized in that the tool magazine is provided within the width of the main body bed, and all of these known documents are for manual replacement of tools. Is not considered.

[0007]

[Problems to be solved by the device]

 Therefore, the present invention provides a tool magazine mounting structure in a machining center that allows a worker to easily and manually replace a tool attached to a tool changer in the machining center when the tool is worn or damaged. It is to develop.

[0008]

[Means for Solving the Problems]

 In this invention, a part of a tool magazine provided on a frame or a supporting base erected on a main body bed of a machining center is provided so as to project outward from the main body bed, and the protrusion of the manual tool for each tool of the tool magazine is provided. It is configured so that it can be easily replaced.

[0009]

[Embodiment of the invention]

 An embodiment of the present invention will be described in detail below with reference to the drawings. A spindle column (3) can be vertically moved on a moving column (2) that horizontally moves in the left-right and front-rear directions with respect to a bed body (1). Tool (X) mounted on a horizontal spindle which is rotatably supported on the spindle head (3) and tools (Y, Y ', Y "...) of the tool magazine (4). Are exchanged by a tool exchanging device (6) equipped with one tool exchanging arm (5), and the main body bed (1) is provided above the moving space of the moving column (2). In a machining center in which a magazine support base (7) is integrally provided, and the tool magazine (4) is provided in the magazine support base (7), a part of the tool magazine (4) is provided so as to protrude from the main body bed width, Manually change the tool located on the protrusion (4a). It is those composed of the mounting structure of the engineering tool magazine in a machining center, characterized in that the target tool.

The tool magazine (4) may be configured so as to rotate horizontally as shown in FIGS. 1, 2, 3 and 4, and as shown in FIGS. 5 and 6. It may have a structure in which it is vertically swiveled.

Further, an oil pan (8) for preventing oil adhering to the tool from dripping along the magazine is provided in the lower part of the tool magazine (4) that swivels in the horizontal direction, and the oil pan (8) is provided. A pan and an outer peripheral cover (9) or a protective cover (10) may be provided. In such a case, one of these oil pan, outer peripheral cover, and protective cover protrudes from the main body bed (1). A space (Z) is formed in the part and an openable / closable opening lid (11) is provided so that the exchange tool (Y) can be directly attached and detached from below. Open the lid (11), remove it, and close it when not needed.

Further, as shown in FIG. 7, even when a plurality of machining centers are used and arranged side by side like a transfer line, they can be accommodated within the width of the maintenance space provided between adjacent machining centers. There is no fear of unnecessarily expanding the parallel pitch.

[0013]

[Effect of the invention]

 According to this invention, the tool magazine is provided so as to project from the main body bed of the machining center and is located above the maintenance space. It is possible to work, and a maintenance space is required not only when using the machining centers as a single unit, but also when they are installed side by side like a transfer line, and there is no problem because the tool magazine projects in that space. Has a very beneficial effect.

Claims (1)

[Utility model registration claims] 1. A main spindle head is vertically movably mounted on a movable column that horizontally moves in the left-right and front-back directions with respect to a bed body, and is mounted on a horizontal main spindle rotatably supported by the main spindle head. The tool and the tool in the tool magazine are exchanged by a tool exchanging device having one tool exchanging arm, and a magazine support base is integrally formed with the main body bed above the moving space of the moving column. In a machining center provided with the tool magazine on the magazine support base, a part of the tool magazine is provided so as to project from the bed width of the main body, and the tool located at the projecting portion is a tool for manual replacement. Tool magazine mounting structure for machining centers.
