摘要:
A drilling machine for drilling securing holes for furniture fittings, for example hinges, includes a drive motor which drives drills by way of a multispindle drilling head with a drill gearing and a plurality of drilling spindles. A stop rule with adjustable stop blocks and a feed device for the feed drill are provided, as well as a press-in die for mounting the furniture fittings on a furniture part. The drilling machine is equipped with a set of replaceable multispindle drilling heads and a set of replaceable stop rules which can be exchangeably fixed to the drilling machine by quick-action clamping devices which can be operated without the use of a tool.

The invention relates to a machine for drilling and boring tubular plates, the workpiece-carrying elevator being embedded, weight compensation being provided by appropriate means, the machining units moving substantially at ground level opposite thrust tubes bearing on the plate before each machining cycle and absorbing tool thrusts. The machine is characterized by an elevator which supports the plate for machining and which moves on slideways with balancing by hydraulic rams in a constant proportion to the weight of the workpiece being machined. Thrust means retain the thrusts of the spindles, the movements of the latter spindles and means being synchronized by means, the tilting torque produced by the thrust of the spindles is limited by the provision at ground level of a closed framing which interconnects all the constituent elements. The invention is of use for drilling and boring any article, more particularly for the baffle plates of heat exchangers, boilers, water purifiers, heaters and the like.

An arrangement for the drilling of holes to apply builders' hardware to windows in which an upper locating rail for accommodating a window frame is located between side members of a framework. A fixed drilling assembly with several spindles is located above the center of the locating rail. The spindles from the drilling assembly are lowerable. Two pipes above and parallel to the locating rail carry two auxiliary drilling assemblies which are coupled by a cable connection. The auxiliary drilling assemblies have several lowerable spindles and can be moved synchronously in opposite directions on the pipes.

A frame structure supports a work surface above which there is provided an elongated head number supporting a series of drills. A torque tube having an axis parallel to and spaced from a line passing through the series of drills is mounted to the frame structure for rotation about its axis. The drill head member is coupled to the torque tube such that rotation of the torque tube initially swings the head member in an arc and thereafter urges the head member through a lost motion coupling arrangement against a pair of spaced parallel guide rails, secured to the frame structure normal to the work surface so that the remaining travel of the drill head is rectilinear. The stiffness of the torque tube assures that one end of the elongated drill head will not move ahead or drop behind the other end so that all holes are drilled simultaneously.

Elongated workpieces such as structural profile members are machined on apparatus suitable for drilling holes or performing other operations at predetermined points by equipment comprising a support with rollers on which the workpiece can be displaced, said support comprising a portal member spanning the workpiece and embodying a tool-carrying cross member having suitable driving tool spindles. The workpiece is located on the support rollers and held in position by vertical and horizontal guide rollers on the portal unit which are pressed into engagement with the workpiece. The cross member which may carry drills or the like is operable towards the workpiece with a cutting feed by means of hydraulic piston devices, and locating means are provided for correctly positioning the workpiece on the rollers. Lengthwise positioning of the cross member is effected by means of an indicator device with a floating zero system which is operated by the displacement of the portal member on the support and is thus available for determining the position of the portal member for effecting drilling at the required points of the workpiece.
摘要:
A multiple-spindle drilling machine is provided with a plurality of drilling spindle units each of which is driven from a common power supply means but which are readily adjustable longitudinally and normal to the drilling spindle axis to provide a multiplicity of drilling patterns as the plurality of units are advanced simultaneously to accomplish a drilling operation. A plurality of drilling spindle units may be adjustably mounted on a common support in a horizontal row and additional horizontal rows may be provided having the identical or different lateral spacing therebetween. The horizontal rows of spindles may be disposed parallel to each other or may be inclined relative to each other.
