Abstract

The device has a tightening block (1) receiving a split adapter sleeve (2) that receives a cylindrical or polygonal unit (6) to be machined, in its hole, and two jig bushings (3, 4). The jig bushing (3) for drilling is replaced by the jig bushing (4) for tapping after a drilling operation. The block has three lateral screws (7) to maintain positioning of the adapter sleeve of different diameters and the jig bushings.

Description

i

  The present invention relates to an apparatus for drilling, tapping, threading all cylindrical or polygonal parts, various materials, strictly in the axis and perpendicular thereto.

  Until then, drilling, tapping or threading with traditional, manual tools, was a real feat, resulting in a considerable number of broken tools and deterioration of machined parts.

  Only the machine tools, with all the necessary preparation, partially allow this type of operation to be carried out, but remain limited as a function of the lengths of the workpieces, and the diameters to be treated, as part of their operations. opportunities.

  The device according to the invention makes it possible to remedy all constraints, all risks of deterioration or bad results, by rigorous guidance, in complete safety, of the various tools: drills, taps and dies.

  The saving of time of adjustment and preparation is considerable.

  The device is constituted by the square section clamping block, in which a bore in the direction of the length has been made.

  Milling parallel to this bore starts a large part of the block, to allow the pinch effect.

  The clamping block receives in the first half of its bore a reduced reduction bushing corresponding to the section of the workpiece.

  The second half is intended to house first, a barrel for guiding the drill, and then a corresponding barrel for guiding the tap.

  The assembly will be held by two lateral screws which block, one, the reduced reduction sleeve on the axis to be machined, the other, the guide barrel, before the final tightening in the vise.

  The device, thus kept perfectly concentric, avoids by pinching, any rotation of the workpiece and its deterioration.

  Note that the workpiece end, may have an indefinite length and unlimited.

  Drilling end of axis will be practiced using a simple hand drill.

  An exchange of guiding cannons will allow tapping by following.

  A device consisting of a bore perpendicular to the bore, on one side of the clamping block, may receive a guide bush, for drilling or tapping, maintained by a third side screw.

  The device will make a drilling and possibly a tapping perpendicular to an axis, to receive either a pin, a screw or a cross assembly.

  To perfect the device, a thread can be made at the end, on the cylindrical or polygonal parts.

  A staggered dice door intended to receive several sizes of dies, raised by a cylindrical bell, of a section equal to the diagonal of the clamping block will cap the latter and benefit from a perfect guiding, in its rotation, by the edges of the clamping block.

  The accompanying drawings illustrate the invention.

  Referring to Figure 1 the device comprises: - A clamping block (1) in which is housed, in one half of its bore, a reduced reduction sleeve (2) for receiving the workpiece (6), in the second half, the guide barrel (3), for drilling. The assembly will be maintained by the two screws (7) corresponding. The guide bushing (4), for tapping, will replace the guide bush (3) for the tapping operation after drilling.

  - A clamping block (1), in which is housed the drilling barrel (3), in the location adapted to one of the faces of the clamping block, perpendicular to the bore, and held by the screw (7) corresponding. The guide bushing (4), for tapping, will replace the guide bush (3) for the tapping operation after drilling.

  - A clamping block (1), which is housed in the end of its bore, a reduced reduction sleeve (2) for receiving the workpiece (6). This set will be maintained by the corresponding screw (7). A staggered sectional door, enhanced by a cylindrical guide bell, of a diameter equal to the diagonal of the clamping block.

  Referring to Figure 2 the device comprises a clamping block (1), which is housed in one half of its bore, a reduced reduction sleeve (2), 15 to receive the workpiece (6), in the second half, the guide barrel (3), for drilling. The assembly will be maintained by the screws (7) corresponding.

  Referring to Figure 3 the device comprises a clamping block (1), which is housed on a half of its bore, a reduced reduction sleeve (2) for receiving the workpiece (6), on the second half, the guide barrel (4), for tapping. The assembly will be maintained by the screws (7) corresponding.

  Referring to Figure 4 the device comprises a clamping block (1), which is housed on a half of its bore, a reduced reduction sleeve (2) for receiving the workpiece (6), and will be maintained by the corresponding screw (7).
