Abstract:
An object of the invention is the provision of a generally improved and more satisfactory machine tool capable of a wide variety of operations. Another object is the provision of improved driving means for the spindle or spindles of a machine tool, particularly a machine tool of the type having two spindles mounted in two separate heads or carriers which are shiftable relative to each other. Still another object is the provision of an improved machine tool having a main spindle mounted on a main gear case (either directly, or on an intermediate member which is mounted on and adjustable relative to the main gear case) and a second spindle mounted on a separate spindle head which is adjustable relative to the mounting means of the main spindle, there being simple and effective driving means for driving either or both spindles in all effective operating positions thereof. A further object is the provision of a machine tool having a spindle head mounted for movement along a guideway to various operative positions and also to inoperative position so placed as to allow space for mounting an auxiliary spindle head or special machining head on the same guideway, and especially such an arrangement so designed and constructed that a single operator can handle all necessary parts when mounting or demounting the auxiliary machining head. A still further object is the provision of simple stop means for limiting the movement of the spindle head along its guideway.
Claim:
A machine tool comprising a supporting member having a substantially horizontal guideway thereon, a spindle head mounted on and movable horizontally along said guideway throughout an operative working range, and a tool spindle rotatably mounted in said spindle head, characterized by the fact that said guideway is sufficiently long so that said spindle head may be moved along said guideway to an inoperative position beyond its working range, thereby freeing a portion of the length of said guideway for attachment thereto of a supplementary tool head and further characterized by driving gear means in said supporting member and located in a position opposite the position of said spindle head when said spindle head is in its working range, to engage with driven gear means in said spindle head, and in a position opposite The position of a supplementary tool head attached to said guideway, to engage with driven gear means in such supplementary tool head.
