Abstract

PROBLEM TO BE SOLVED: To reduce the swinging of a pendant operation part to improve operability during the operation of a machine, by assembling a swing preventive member in the hanging arm of a pendant operation part. SOLUTION: A falling preventive jaw part 6 is externally fitted and fixed to the top of a hanging arm 3, and a buffer 7 is nippedly mounted between the lower surface of the faw part 6 and the inner surface of a horizontal arm 2, to externally fit and fix an automatic self-aligning bearing unit 8 to a neck part adopted as the rotary bearing part of the arm 3. In editing a program during the operation of a machine, the arm 3 of a pendant operation part 1 can be operated freely in oscillation and rotation by the jaw part 6, the buffer 7, and the bearing unit 8 in the connection part with the arm 2. Consequently vibration from a machine main body and so on can be absorbed and reduced to eliminate transmitting swinging to the operation part 1 directly, thereby safely operating program editing and so on.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing a pendant operating portion from swinging in a processing machine or the like integrated with a control device.

[0002]

2. Description of the Related Art In a processing machine such as a turret punch press integrated with a control device equipped with a numerical control device, a control device is provided on a base provided directly on the main body of the processing machine via a vibration isolator such as a vibration isolating rubber. The main body is mounted. Usually, a machine or the like is fixed to the floor with anchor bolts, but it is customary to install a vibration isolator or the like on the installation surface of the processing machine main body in order to avoid the influence of ground vibration.

[0003]

However, in the above-mentioned conventional example, even when the vibration isolator is used for the processing machine main body, the machine itself largely shakes, so that the control device itself is affected and shakes. There is a problem that the swing is transmitted directly to the pendant operation unit, and it becomes difficult to edit a program or the like in the operating pendant operation unit.

The present invention has been made in view of the above points, and provides a pendant operating portion swing preventing method which can improve operability during operation of a machine and can prevent a failure due to parts falling off due to swinging of a pendant. The purpose is to do.

[0005]

The present invention can solve the above-mentioned problems by providing the following constitution.

(1) In a pendant operating section of a processing machine or the like, which is provided with a numerical control device and has an operation section having a display section, which can be freely moved and operated by an operator, a horizontal extending from the numerical control apparatus is provided. A pendant operation part swing prevention method, wherein a swing prevention member is incorporated in a suspension arm of the operation part in a suspended state at an end of the arm.

(2) The swing-preventing member is provided with a flange for preventing dropping at a portion connected to the horizontal arm and at a position located at the head of the hanging arm, and a contact between the lower surface of the flange and the horizontal arm is provided. A shock absorber for reducing shock or vibration is clamped on the surface, and the suspension arm swings, and a self-centering type is provided below the flange so as to be rotatable, and on the neck of the suspension arm. The pendant operating part swing prevention method according to the above (1), further comprising a bearing unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.

FIG. 1A is an overall side view of a numerically controlled turret punch press incorporating the pendant operating portion swing prevention method according to the present invention, FIG. 1B is a detailed longitudinal side view, and FIG.
Is a detailed vertical sectional side view of another embodiment, and FIG. 3 is a schematic side view showing a configuration of a conventional example.

Referring to the drawings, reference numeral 1 denotes a pendant operation unit, 2 denotes a horizontal arm, and 3 denotes a hanging arm. The horizontal arm 2 is rotatably supported at one end by a numerical controller S and extends horizontally. The suspension arm 3 is suspended from the distal end, and the suspension arm 3 is provided with an operation box serving as an operation unit to constitute the pendant operation unit 1.

Reference numeral 4 denotes an anti-vibration rubber, and 5 denotes an anti-vibration device. The turret punch press TP main body is fixed to the floor via an anti-vibration device 5 with an anchor bolt (not shown) at the time of installation. The numerical controller S is mounted on a base B provided on the main body frame via a vibration-proof rubber 4.

Reference numeral 6 denotes a collar for preventing a fall, 7 denotes a shock absorber (damper, absorber, etc.), 8 denotes a self-aligning type bearing unit, and 9 denotes a slide bearing. A fall prevention flange 6 is externally fitted and fixed, a buffer 7 is sandwiched between the lower surface of the fall prevention flange 6 and the inner surface of the horizontal arm, and a neck serving as a rotary bearing of the suspension arm 3 is provided. A self-aligning type bearing unit 8 is externally fitted and fixed so that the head can swing, and the pendant operation unit 1 rotates.
It is configured to be able to swing freely. The vertical arm 1 connecting the numerical control device S and the horizontal arm 2
0 is provided with a sliding bearing 9 so that the horizontal arm 2 can rotate around the vertical arm 10.

Reference numeral 3a denotes a wiring hole through which a transmission wiring connecting the numerical controller S and the pendant operation unit 1 can be inserted.

The operation will be described based on the above configuration.

In a processing machine such as a turret punch press or a bender with a so-called pendant operation unit, which allows the operator to operate the operation box while moving the operation box freely, the operator executes program editing and the like while the machine is operating. At this time, the hanging arm 3 of the pendant operating unit 1 is connected to the horizontal arm 2 at the connection portion with the horizontal arm 2, a flange 6 for preventing falling provided at the top of the hanging arm 3, a buffer (a damper, an absorber, etc.). 7. The self-aligning bearing unit 8 provided on the neck serving as the rotation bearing unit can swing and rotate freely to absorb vibrations from the machine body. Reduce
The shaking is not transmitted directly to the pendant, and operations such as the program editing can be safely executed.

Another embodiment will be described with reference to FIG.

A collar 6a provided at the top of the suspension arm 3 which is connected to the horizontal arm 2 in a suspended state.
The bottom portion is formed in a spherical shape, and the shape of the receiving seat 6b for loosely fitting and holding the flange portion 6a is also formed in a spherical shape,
The flange 6a is rotatable and slidable, and a vibration absorbing buffer 7a is provided in close contact with the lower surface of the receiving seat 6b, so that the swing of the pendant operating unit 1 is reduced and the swing and rotation of the pendant operating unit 1 are reduced. Both are free, and the same effects as in the above-described embodiment can be obtained.

TU is an upper turret, TL is a lower turret, and C is a clamping device.

FIG. 3 is a schematic side view showing a conventional structure, in which the bearing is only a slide bearing, and the swinging operation is impossible, and at the same time, no shock absorber such as a damper or an absorber is used. Therefore, an example of a situation in which vibration from the machine body cannot be reduced will be described.

[0020]

According to the present invention, it is possible to reduce the swing of the pendant operating portion and improve the operability by using the swinging structure of the rotating shaft and the bearing portion of the pendant.
