Description

[Detailed Description of the Invention] The present invention relates to a device for protecting the end face of a front plate attached to the front surface of a headstock of a horizontal boring machine or the like.

A front plate is attached to the front of the headstock of large machine tools such as horizontal boring machines.
Various processing attachments are attached to the front plate. When attaching this attachment to the front plate, it is necessary to completely remove chips, cutting oil, etc. adhering to the front end surface of the front plate, but in the past, this removal work was done manually. It was not possible to automate the exchange of attachments, which was a major stumbling block in efforts to achieve unmanned operation.

In view of the above-mentioned conventional problems, the present invention is a protective plate that eliminates the need to clean the front end surface of the front plate when attaching an attachment, and therefore enables automatic replacement of attachments. a main body that can be brought into close contact with the front end surface of a front plate attached to the front surface of the headstock; a means fixed to the main body for sealing the front end surface of the front plate; a clamp pin for attaching and detaching the main body to the front plate; and a fluid and electrical connection port provided at the.

Embodiments of the present invention will be described below based on the drawings. 1 is a front view, FIG. 2 is a side view, and FIGS. 3 and 4 are partially detailed views of FIG. 2. In the figure, 1 is the plate body, 2 is the front plate, and 3 is the headstock. A plurality of nozzles 4 are embedded around the main shaft hole 5 for blowing out cutting oil. The spouting nozzle 4 has a spherical shape and has a cutting oil spouting hole 6, and is rotatably attached via a spherical washer 7 and a presser foot 8, with the spouting hole b directed toward the machining part position a. It can be rotated arbitrarily. Reference numeral 9 denotes a cutting oil introduction hole, which communicates with each of the four jetting nozzles described above, and an automatic oil supply connection port 10.
The cutting oil that is pressure-fed from the hose 11 is introduced into the jet nozzle. 12 is a seal plate that covers the entire 1' area of the front plate's outer periphery (4 sides in this figure)
This prevents chips and cutting oil from flowing into the front of the front plate. Reference numeral 13 denotes clamp pins for automatic replacement, and a plurality of them protrude from the rear surface of the plate main body 1, and are automatically clamped by a clamp device (not shown in this figure) built into the front plate 2 side, and attached to the front surface of the front plate 2. Ru. Reference numeral 14 indicates a notch provided in the plate body 1 to prevent interference when the changer arm for automatic tool changing rotates.

FIG. 5 shows a detailed cross section of the automatic refueling joint. In the figure, reference numeral 15 is a holding block for the automatic refueling connection port 10, which is paired with block 16 of the refueling connection port located on the front plate 2 side. It is provided in 17 indicates an automatic connection coupler. Also, when installing the attachment, the hydraulic connection ports 18, 19,
20, an electrical control connection port 21, etc. are arranged in the block 16 of the oil supply side connection port. 2
2 and 23 indicate automatic connection electrical identification devices. This is arranged facing the attachment side and the machine body side. This identification device is provided with a unique combination of shell terminals for each attachment, and identifies which attachment is attached. In addition to this identification, signals from the limit switch and proximity switch are simultaneously detected using the remaining terminals. Reference numeral 24 denotes a stopper that also serves as a reference seat for inserting the protection plate into a storage (not shown).

In the above-mentioned embodiment, a notch is provided to avoid interference between the spindle through hole and the tool changing arm, so automatic tool changing to the spindle is possible even when this device is attached to the front plate. Equipped with an attachment identification function, it is effective for automatic attachment replacement. It can also be used as a cutting oil supply device and a coolant device.

As explained above, according to the present invention, there is no need to remove chips and cutting oil adhering to the front plate surface, and by providing fluid and electrical connection ports, cutting oil piping and power supply terminals can be automatically connected and disconnected. By doing so, it is possible to greatly shorten the setup time when replacing attachments, and it is possible to improve efficiency. At the same time, it is possible to completely automate the attachment exchange, and the work can be unmanned, resulting in significant labor savings. Furthermore, since the surface and outer periphery of the front plate on the machine body side can be completely protected, attachments and the like can be mounted smoothly and with high precision. Furthermore, even when this protective cover is attached to the front plate, cutting oil can be supplied to the machining position, and a function can be provided to identify that the protective cover is attached.
