Definitions

  • a milling machine has a main column'p'rovided with a vertical guideway on its front face'aud a spindle stock at its top.
  • a knee supporting a work table moves -ver- 3,397,616 Patented Aug. 20, 1968 a spindle stock 14 displaceable in a front and rear direction along horizontal gu ideways 15.
  • the spindle stock coutains the usual conventional horizontal spindle, the front end of which is indicated in general at 16.
  • Another horizontal guideway extends along the top of the spindle stock 14, in a direction parallel to the guideway 15, and on this second guideway there is movably mounted, in a front to rear "direction, a second spindle stock 18 which carries a spindle head 20 provided with a. spindle 21.
  • the spindlehead 20, is rotatable in the conventional manner about a horizontal axis, parallel to the above mentioned horizontal guideways and intersecting the axis of the tically on the guideway on the main column.
  • a vertically extending stationary bracing sltructure'having a vertical guideway on its rear face engaged with'a vertical guide part on the front face of the kne'e,'to give added stability to the knee.
  • Handwheels are'rnounted'on the front of the vertical bracing structure, for'performin'g various adjustments such as thevertical 'adjust'ment'of the knee and the horizontal adjustment of thespindle'stock, these handwheels remaining always ata predetermined convenient elevation notwithstanding upward'ar'id' downward movements of'the knee and work table.
  • a counterstay for a spindle head has asupporting post which is supported from the vertical bracing structureand which can be dropped down at least partly into a socket in the vertical bracing structure when it is not in'use.
  • This invention relates to a milling machine, and more particularly to a milling machine of the type iiiWhich the work table is supported from a vertically adjustable spindle 21. Therefore the spindle 21 is not necessarily always in a vertical position, but may be turned to various angular positions. However, it is quite frequently used in a "vertical position and is commonly referred to, in a machine of this general type, as the vertical spindle.
  • Still an'other'object is the provision, in a milling 'nia chine of the knee type, of rigid means serving the'double' purpose of promoting rigidity in the knee at any des ired vertically adjusted position thereof, and at thesame time furnishing a supportfor handwheels or "other control's which can remain at a fixed elevation at the height most convenient to the operator, regardles'sof the upward and same time anchoring a counterstaysupport when the counterstay is in use, and containing the support when the counterstay is not in use.
  • FIG. 1 is a side elevation, somewhat schematic and with parts broken away, of a milling machine in accordance with a preferred embodiment of the invention.
  • FIG. 2 is a perspective view of certain portions of the machine shown in FIG. 1.
  • the machine of the present invention in its preferred embodiment, comprises a rigid base 10, and a rigid column 12 rising from the rear portion of the base. On the top of the column 12 is with corresponding guide portions at the front of the knee structure 24. On the box 32, preferably on the front face thereof, there are suitable control members or manipulating members such as the handwheels 36 and 38.
  • the handwheel 36 is connected by bevel gears and shafts, as shown schematically in FIG. 1, with a handwheel 36' mounted on the side of the column 12, and with a worm 40 which, by means of a wormwheel 42, drives the vertical feed screw or feed spindle 26 for 3 adjusting the height of the knee 24 and work table 28.
  • the handwheel 38 is connected through shafts and bevel gears with a handwheel 38' on the side of the machine column 12, and with conventional feeding means including, for example, the worm 46, Wormwheel 48, and screw feed spindle 50 for imparting forward and rearward horizontal movements to the spindle stock 14.
  • conventional feeding means including, for example, the worm 46, Wormwheel 48, and screw feed spindle 50 for imparting forward and rearward horizontal movements to the spindle stock 14.
  • the control members 36 and 38 are mounted on the stationary box structure 32 rather than on the vertically movable knee 24, these control members remain at a constant elevation and such elevation can be designed to be at the most convenient height for the operator. Thus he can easily operate the control members at all times, overcoming the disadvantage experienced in conventional machines of the knee type, where the control members, if
  • the box structure 32 may be provided with a vertical socket or opening 51 in which a vertical post or support 52 may be seated when desired.
  • This post 52 serves to support the forward end of a counterstay or brace 54 for the vertical spindle head 20, when it is desired to use such a brace for giving greater rigidity to the spindle head.
  • a suitable clamp (conventional per se) clamps the post 52 in its elevated position when the counterstay is in use, and permits it to be dropped to a position wholly or mainly within the socket 51 when the counterstay is not being used.
  • the massive box-like structure 32 of the present invention having a relatively large area in plan or in horizontal section, gives adequate support against horizontal movement of the front end of the knee, and thus, in combination with the rear guideway 22, holds the knee rigidly against horizontal torsional movements.
  • a massive box-like structure serves admirably as a mounting place for mounting the controls and operating elements such as 36 and 38, which are always at a convenient height as above explained.
  • suitable clamping means may be used to clamp the front of the knee to the guideway 34 on the box 32, in any adjusted elevation of the knee, when greater stability in a vertical direction is desired.
  • the present construction is distinguished basically from machine tools in which the work table is not supported on a vertically adjustable knee but, rather, directly on the bed of the machine.
  • machines i.e., machines of the bed type
  • the parts which carry the control or operating elements are of greater or lesser rigidity.
  • a milling-machine of the type comprising a base, a machine columnrising from said base and having a vertically extending guideway, a vertically movable knee projecting forwardly from said guideway and having its rear side ,guidedfor upward and downward movement along said guideway,. a work table.
  • a milling machine of the type comprising a base,
  • a machine column rising from said base and having a placing forces encountered during the machining operation by mounting the control members at a fixed elevation on a rigid box-like structure which at the same time serves as an additional support or brace for the knee, particularly resisting horizontal displacing forces to which the knee may be subjected.
  • a milling machine of the type comprising a base, a machine column rising from said base and having a vertically extending guideway, a vertically movable knee vertically extending guideway, a vertically movable knee projecting forwardly from said guideway and having its rear side guided for upward and downward movement along said guideway, a work table carried by said knee, a tool spindle mounted on said column and adapted to carry a tool for operating on work carried by said table, a spindle stock in which said tool spindle is mounted, and a counterstay for bracing said spindle stock, characterized by the provision of stationary upstanding rigid means at the front of, said knee, saidmeans having a vertical guideway on its rear side for engaging the front side of said knee to give to said kneeadded stability against displacing forces, said upstanding rigid means having an opening therein, and a vertical support mounted on said upstanding rigid means for supporting a part of said counterstay, said vertical support being arranged so that it may be loweredinto and received at least
