Abstract

PURPOSE: A device for opening and closing an APC(automatic pallet changer) of machining center is provided to replace a pallet by making the rest door also operated when one side door is operated in the APC door. CONSTITUTION: One side door among a right and a left door(20a,20b) is opened by holding a handle of the left side door in order to replace a work piece to process and a processed work piece. A guide bar(25a) for supporting the left side door rotates a first circumscription gear by the operation force of worker. Accordingly, a second circumscription gear butted with the first circumscription gear is interlocked. A right door is opened symmetrically with the left door through the guide bar of the right side.

Description

Machining Center A / P Door Opening and Closing Device

The present invention relates to an opening / closing device of a machining center APC door, and more particularly, when one door is operated in an APC door configured in a sliding form of left and right to replace a pallet, a machining center APC door is operated so that the remaining doors work together. It relates to a switchgear of.

In general, the machining center refers to a complex machine tool consisting of a boring machine, a milling machine, and a drilling machine, and is a vertical MC, horizontal MC, and vertical / horizontal hybrid type machines depending on the direction of movement of the main shaft. Separate. There are three kinds of machining center motions: linear motion, rotary motion and spindle rotation. These motions are controlled by numerical control servo and NC spindle to control positioning and spindle speed. The machining center consists of an automatic tool changer (ATC) and an NC machine that automatically changes the machine body and 20 to 70 tools to suit cutting conditions. Multi-axis machining and multi-processing can be done with just one setting, which is useful for automating the processing of small quantity parts. It is a device to secure enough working capacity in recent machining centers. It is a function to increase the reliability of APC (Automatic Pallet Changer or Pool) and machining. ① Process monitoring function, ② Automatic measurement and correction function, ③ Adaptive control (AC) and fault self-diagnosis are added to provide a flexible manufacturing system (FMS) that increases the flexibility of machining and machining processes.

As shown in FIGS. 1 and 2, the machining center is provided with a main body cover 10 which protects the user from the machine body and prevents cutting oil or fine cutting chips from scattering and contaminating the workplace. In particular, a sliding door type APC door 20 is configured to slide from the main body cover 10 on the APC side for the replacement of the workpiece to be processed and the workpiece to be processed.

On the other hand, the left and right doors 20a and 20b of the APC door 20 are configured such that the pivot point 22 is unified in one place.

In addition, the conventional APC door 20 is configured with guide rails (not shown) on the upper and lower portions of the main body cover 10 so that the left and right doors 20a and 20b are opened and closed with the same action.

However, such a conventional APC door 20 is configured only in the sliding form around the pivoting point 22, but only when the operator grasps the left and right doors 20a and 20b at the same time to open the door completely. It was very cumbersome because it was done.

In addition, since the conventional APC door 20, that is, the left and right doors 20a and 20b are moved by separate operations, the same opening and closing state cannot be maintained due to vibration in the machine.

Therefore, the present invention has been made in order to solve the above problems, the object of the machining center to operate the one side door in the APC door configured in the sliding form of the left and right to replace the pallet, the remaining door is also operated together An APC door opening and closing device is provided.

In order to achieve the above object, the present invention, the left and right door is configured to slide in the sliding form on the guide rail of the body cover around the pivot point to the opening and closing device of the machining center APC door to replace the workpiece of the pallet In

First and second external gears rotatably installed at an upper end of the main body cover and engaged with each other; One end is fixedly coupled to the rotation center axis of the first and second external gear, and the other end is fixed to each door is provided with a guide bar for guiding each door to the guide rail of the body cover to slide on a certain trajectory Has the features configured.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail based on attached drawing.

3 is a plan view showing the opening and closing device of the machining center APC door according to the present invention.

The configuration of the present invention, the left and right door (20a) is configured to slide in the sliding form on the guide rails (23a) (23b) of the main body cover 10 around the pivoting point 22 to replace the workpiece of the pallet In the opening and closing device of the machining center APC door,

The first and second external gears 24a and 24b which are rotatably installed at the upper end of the main body cover 10 and mesh with each other are configured.

The first and second external gears 24a and 24b are preferably provided to face each other on a horizontal line parallel to the pallet from the center of rotation.

In addition, one end is fixedly coupled to the rotation center axis of the first and second external gears (24a, 24b), the other end is fixed to each of the door (20a, 20b) to each of the door (20a, 20b) ) Is configured to include guide bars 25a and 25b guided to the guide rails 23a and 23b of the main body cover 10 so as to slide on a predetermined trajectory.

Reference numeral 26a, 26b is a handle that can open and close each door (20a, 20b).

Referring to the operation of the present invention configured as described above are as follows.

For the exchange of the workpiece to be processed and the workpiece to be processed by holding the handle of one of the doors, for example, the left door 20a of the left and right doors 20a and 20b according to the present invention, the left door 20a The guide bar 25a for supporting the first rotation gear is rotated by the operator's operating force. Accordingly, the second external gear () engaged with the first external gear () is interlocked with the first external gear () so that the right door () is symmetrically opened with the left door () through the guide bar 25b on the right side.

Since the operation state in which the door is closed is made in reverse to the above, detailed description thereof will be omitted.

The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

Applying the present invention as described above, by operating one of the left and right doors (20a, 20b) consisting of the APC door 20 by the movement of the external gears (24a, 24b) engaged with each other. Since the other door is configured to interlock, there is an advantage that the operator's convenience is increased.
