摘要： The present invention discloses a self-locking head-replaceable hard alloy drill bit, comprising a cutter head and a cutter bar. The cutter head is disposed at the upper end of the cutter bar, a cylindrical handle is disposed at the lower part of the cutter head, a vertical cylindrical handle holding slot or round handle holding hole is disposed at the upper end of the cutter bar, at least two cutter head notches are disposed on the drilling body of the cutter head, and each cutter head notch is formed by intersecting a first cutter head contact face and a second cutter head contact face, which are vertical or vertically oblique. At least two protrusions which protrude upward are disposed on the wall of the upper end of the cutter bar and have the same number as the cutter head notches. The protrusions have such a structure that during the process of assembling the cutter head and the cutter bar, the cutter head ridge edges and the inner surfaces of the protrusions are in non-contact fit, interference fit and non-interference fit in sequence. According to the present invention, the drill bit realizes rapid assembly/disassembly between the cutter head and the cutter bar, remains stable after assembly, has the self-locking function, and ensures highly-reliable transmission of the cutter head and the cutter bar, and the assembly/disassembly operation does not need screws for fastening and is very convenient and rapid.

摘要： The modular carrier tool (2), in particular drilling tool, extends along a central longitudinal axis (4) in axial direction (6) and comprises a carrier (8) as well as a tool head (10) that can be reversibly mounted on the front-end of the carrier (8). The carrier (8) has a head retainer (14) for the insertion of the tool head (10) as well as clamping webs (24), which radially delimit the head retainer (14) and also have bearing surfaces (28). The tool head (10) comprises clamping surfaces (35) extending in axial direction as well as underhead bearing surfaces (34). In a mounted state the clamping webs (24) clamp the tool head (10) in radial direction to the clamping surfaces (35) and the underhead bearing surfaces (34) are pressed against the bearing surfaces (28). In order to generate a force component (K) acting in radial direction unto the clamping webs (24), the bearing surfaces (28) as well as the underhead bearing surfaces (34) are tilted in radial direction towards the central longitudinal axis (4) by a tilt angle α. This particularly supports the radially exerted clamping force of the elastic clamping webs (24).

摘要： A cutting tool for rotary cutting includes a rotatable basic body and a replaceable cutting part or loose top, which is connectable to the basic body via a male/female coupling, which includes a groove and a male part. The groove is formed in a front end of the basic body and is delimited by a bottom surface and two side surfaces. The male part is insertable into the groove along the axis of rotation and protrudes rearwardly from the loose top. The male part has an end surface and two flank surfaces. In the front part of the basic body a forwardly open slot is formed, which separates two elastically deflectable legs wich clamp the male part in the groove. In either the end surface or the bottom surface a recess is formed for receiving a projection on the other surface. The recess is larger than the projection in order to enable the male part to reciprocate a short distance in the groove, whereby the loose top is self-centering with respect to the axis of rotation.

摘要： A rotary milling cutter has a cutter body mountable on an adapter. A first side of the adapter is provided with circumferentially arranged drive pins centered about a centrally positioned, conically tapered male locating member. A first side of the cutter body is provided with circumferentially arranged drive grooves centered about a centrally positioned, conically tapered female locating member. The drive pins have a base portion connected to a head portion while the drive grooves have an insertion portion connected to a retaining portion. During assembly, the first side of cutter body and the first side of the adapter are first moved into an initial mating position in which the drive pins enter the insertion portions of the drive grooves and the male locating member enters the female locating member. The cutter body is then rotated relative to the adapter such that the drive pins enter the retaining portions of the grooves. With the adapter retained in an inverted position with its drive pins extending vertically downward, the cutter body may thus be supported by the heads of the drive pins. A center bolt normally resident in a throughbore of the cutter body is then screwed into a threaded bore formed in the male locating member of the adapter.
