Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a control box for a machine tool.
In particular, it relates to improvements that make transportation easier.

[Conventional technology]

Historically, control boxes for machine tools have been small items that have the function of accommodating electromagnetic switches for controlling lead screw drive motors, etc.
With the development of various automatic machine tools, they gradually became larger. At the same time, a so-called pendant-type operating box that extends from the machine tool body was developed with the aim of improving operability and safety. The conceptual configuration (plan view) of the machine tool at this stage is shown in Figure 2. In the figure, 1 is a machine tool main body, 2 is a control box, 3 is a pendant type operation box, and 4 is an arm extending from the machine tool.

By the way, for automated machine tools such as NC machine tools, a large amount of wiring 5 is required between the machine tool body 1 and the control box 2, and this wiring must be done after the machine tool is installed. Since this is complicated and there is a possibility of erroneous connection, it was decided that the machine tool main body 1 and the control box 2 were connected from the beginning, as shown in FIG. At the same time, the arm for suspending the operation box was attached to the control box instead of being attached to the machine tool itself.

[The problem that the idea aims to solve]

In the machine tool control box shown in Fig. 3, the pendant type operation box can be placed at the optimal position for operation, so it is suitable for operation. Since it has poor properties and is inconvenient to transport, it is necessary to disassemble it or use reinforcing support means during transport, resulting in extremely high transport costs.

The purpose of the present invention is to eliminate this drawback, and is arranged in close contact with the machine tool body 1.
A pendant arm 4 is provided which protrudes from the top, extends horizontally, and whose tip extends downward.
Improves stability during transportation of a machine tool control box with a pendant type operation box 3 suspended from the tip of the machine tool.
The object of the present invention is to reduce transportation costs without requiring any special additional means.

[Means to solve the problem]

The above purpose is to provide a machine tool control box 2 that is disposed in close contact with a machine tool body 1, and a pendant that protrudes from the top of the machine tool control box 2, extends horizontally, and extends downward. A type arm 6 is provided, and this pendant type arm 6
The horizontal part 61 of the arm 6 can be bent and rotated in the horizontal direction, and the pendant-type operation box 3 is suspended from the tip of the arm 6, and the pendant-type operation box 3 is folded to form a recess that accommodates the operation box 3. 7 is formed by a combination of the machine tool main body 1 and the machine tool control box 2, and the operation box 3 suspended from the pendant type arm 6 is accommodated in the recess 7 only during transportation. This is achieved by a machine tool control box.

[Effect]

As mentioned above, the horizontal part 61 of the pendant arm 6 is free to bend and rotate in the horizontal direction.
On the other hand, since a recess 7 corresponding to the dimensions of the pendant type operation box 3 is formed by the combination of the machine tool body 1 and the machine tool control box 2, the horizontal part 61 of the pendant type arm 6 is removed during transportation. It can be folded horizontally and accommodated in the recess 7 mentioned above. Therefore, stability can be improved and transportation costs can be reduced without requiring special means during transportation.

After arriving at the site, the pendant type arm 6
By extending the horizontal portion 61 of the pendant-type operation box 3, the pendant-type operation box 3 can be placed at the optimal position for operation, as in the case of the prior art.

However, the horizontal part 61 of the bendable and rotatable pendant-type arm 6 according to the present invention is to be used in a fixed position after installation on site, and there is no consideration given to freely changing its position. Its mechanical strength does not have to be very high, and its range of movement is limited between the transport accommodation recess 7 and the optimal operational position, which is fixed after field installation. Therefore, there is an advantage that there is no burden on cost at all.

〔Example〕

Hereinafter, a control box for a machine tool according to an embodiment of the present invention will be described in further detail with reference to the drawings.

See Figures 1a and 1c Figure 1a shows the horizontal part 61 of the pendant arm 6.
FIG. 1c is a plan view showing the extended state in use, and FIG. 1c is a perspective view thereof.

In the figure, 1 is the machine tool body, 2 is a control box, 3 is a pendant type operation box, and 6
1 is the horizontal part of the bendable pendant-type arm 6 (see FIG. 1c) according to the gist of the present invention, which is shown in the distracted state. In this state, the operation box 3 can be used freely, but is fixed at the optimum position for operation. 7 is a recess according to the gist of the present invention, the size of which is determined in accordance with the size of the operation box 3.

Refer to Figure 1b. The figure shows that the pendant type operation box 3 is placed in the recess 7 by bending the horizontal part 61 of the pendant type arm 6 in the horizontal direction.
FIG. In this state, stability during transportation is good, and transportation costs can be reduced without requiring special additional means during transportation.

As described in the [Function] section, the reason why the horizontal portion 61 of the pendant type arm 6 according to the present invention is bendable is because it is bent during transportation and the pendant type operation box 3 is accommodated in the recess 7. After arriving at the site, the operation is limited to extending and fixing the pendant type operation box 3 at the optimal position for operation, and it is not assumed that the pendant type operation box 3 can be moved to any position according to the operator's request. Therefore, there is no need to particularly increase the mechanical strength of the pendant type arm 6 for suspending the pendant type operation box 3 whose own weight is about 50 kg.

[Effect of idea]

As explained above, in the machine tool control box according to the present invention, in the machine tool control box disposed in close contact with the machine tool body, the machine tool control box has a structure that protrudes from the top and extends horizontally. A pendant-type arm is provided that extends from above to downward, and the horizontal part of this pendant-type arm can be bent and rotated in the horizontal direction, and a pendant-type operation box is suspended from the tip of this arm. A recess in which the pendant type arm is folded and the operation box is accommodated is formed by the combination of the machine tool body and the machine tool control box. Since it is housed in a recess only at the bottom, stability is improved and transport is possible easily.
