Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a switch box that is disposed on the side of a machine tool via a support or the like and has a built-in switch such as a start switch or an emergency stop switch.

(Conventional technology) A conventional switchbox is shown in FIG.

In the figure, a shows a switchbox main body mounted on a support column b, and a pair of left and right starting switch operators c, c and an intermediate emergency stop switch operator d are arranged on the upper surface of the switchbox body.

The reason why the starting switch operators c are arranged in a pair is to ensure that the machine tool is started only when they are pressed at the same time, and to prevent inadvertent starting.

(Problem that the invention aims to solve) By the way, workers who handle machine tools wear rubber gloves to avoid injuring their hands when attaching and detaching workpieces, and operate switch controls c and d while wearing the gloves. Therefore, there is a problem in that the cutting fluid that adheres to the gloves adheres to the operators c and d and the top surface of the box body a when the switch is operated, and this drips down onto the floor along the circumferential surface of the box body a, staining the floor.

The purpose of the present invention is to provide a switch box that solves these problems.

(Means for Solving the Problems) In the present invention, in order to achieve the above object, a gutter portion is formed on the upper side of the circumferential surface of the switch box main body on which the switch operator is arranged.

(Function) Cutting fluid dripping from the top surface of the switchbox body is received by the gutter and prevented from falling to the floor.

In addition, since a gutter is provided on the upper side of the circumference of the switch box body, when pressing the switch operator with your thumb, you can hook your other fingers on the bottom of the gutter and use your grip force to move your fingers without moving your entire arm. In particular, in a device equipped with a pair of starting switch operators, it is easier to perform simultaneous operations with a finger rest, and even repeated starting operations become less tiring.

(Example) An embodiment of the present invention shown in FIG. 2 and below will be described.

In the drawing, 1 is a column installed on the side of the machine tool, 2
1 shows a switch box body mounted on the support column 1, and a pair of left and right start switch operators 3 ₁ , 3 ₁ and an intermediate emergency stop switch operator 3 ₂ are arranged on the top surface of the main body 2. , the respective operating elements 3 _{1 and} 3 ₂ can be operated by pushing against the spring _3a as shown in FIG. The start switches connected in series are activated to start the machine tool, and when the emergency stop switch operator ₃₂ is operated, an emergency stop switch (not shown) in the main body 2 is activated. It was activated so that the machine tool operation was stopped.

A gutter portion 4 extending all the way around is formed on the upper side of the circumferential surface of the main body 2, and each of the operating elements 3 is
₁ , 3 ₂ and the upper surface of the main body 2 so that when it drips down from the upper surface, it can be received by the gutter section 4, and a tube 5 connected to an appropriate collection tank is connected to the gutter section 4. The cutting fluid collected in the gutter section 4 was then returned to the collection tank.

Note that the gutter portion 4 can be integrally molded with the main body 2, but in the illustrated example, the gutter portion 4 is formed by fixing a frame 6 having an L-shaped cross section to the circumferential surface of the main body 2. I took it as a thing.

Further, when the upper surface of the main body 2 faces obliquely upward, the gutter portion 4 may not be formed on the upper circumferential surface portion in the oblique direction.

By the way, the gutter 4 also functions as a place to hang your fingers when operating a switch. For example, when operating a pair of starting switch operators 3 ₁ , 3 ₁ , the appropriate fingers of both hands are shown in Fig. 3. By hanging it on the bottom of the gutter part 4 in this way, it is possible to press both the operating elements 3 ₁ and 3 ₁ simultaneously with good operability without moving the entire arm and just by moving the fingers using grip strength.

In this case, although some cutting fluid adheres to the bottom of the gutter 4, the third
It is advantageous to form a second gutter section 7 located below the gutter section 4, as shown by the imaginary line in the figure, to prevent this cutting fluid from falling onto the floor.

(Effect of the invention) As described above, according to the invention, even if the cutting fluid adheres to the top surface of the switchbox body due to the switch operation, the cutting fluid dripping from the top surface is removed by the gutter formed on the upper side of the circumferential surface of the main body. This has the effect that the switch operator can be operated by placing one's finger on the bottom of the gutter, thereby improving operability.
