| Abstract:
A milling &c. machine provided with over-arms comprises a standard, Fig. 1, a main spindle mounted for rotation in the standard, an attachment having a housing carrying a drive spindle, means on the side of the standard for supporting the attachment housing whereby this may be adjusted longitudinally, and driving means between the main spindle and the attachment spindle for maintaining continual driving engagement with the latter in any of its positions of adjustment while leaving the main spindle free to function in its normal manner. The attachment housing sleeve is supported in a split bracket, Fig. 12, carried at the side of the standard wherein the sleeve is rotatably and axially adjustable ; the forward end of the sleeve carries a rotatable head, Fig. 9, which houses the vertically adjustable attachment spindle. This spindle is driven by bevel gearing from a central spindle, which runs the length of the attachment sleeve and is rotatably mounted therein. A long gear 60 integral with the spindle is driven in all positions of axial adjustment of the spindle by gearing connecting the gear 60 with the main spindle of the machine. The gearing for this purpose is housed in a casing, Fig. 12, rotatable about the axis of the main spindle and held, with the last wheel of the driving train in alignment with either one of the openings for the over-arms, or with the attachment bracket, by a stud. This enables the attachment housing to be positioned in the place of either of the over-rms with the drive to the main spindle in engagement. One of the wheels of the train may be slid out of engagement to disconnect the drive to the attachment. A hinged bracket, Fig. 4, is clamped around the over-arms and a part of the attachment to obtain rigidity, and graduations indicate the inclination of the attachment spindle to the horizontal. The end of the attachment driving spindle, Fig. 8, is supported in a bearing at the rear end in the sleeve, a telescopic guard encloses the end of the sleeve, the parts of the guard being forced into the collapsed position by a tension spring and the outer end of the sleeve drawing these apart when the attachment is moved axially rearwardly such as when positioning the attachment in the inoperative position, Fig. 1. A lubricator, Fig. 8, is connected to a pipe, which passes into the hollow end of the spindle for distribution.
Claim:
A milling or like machine tool provided with over-arms comprising a standard, a main spindle mounted for rotation on the standard, an attachment having a housing carrying a drive spindle, means on the side of the standard for supporting the attachment housing whereby the latter can be adjusted longitudinally and driving means between the main spindle and the attachment spindle for maintaining continual driving engagement with the latter in any of its positions of adjustment while leaving the main spindle free to function in its normal manner. |
