Embodiment Construction
[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0013] Such as figure 1 As shown, the present invention includes a knife magazine support 1, a knife magazine swing frame 2, a knife magazine 3, a knife arm 4, a collision block 5, and a guide plate 6. For the structure of tool magazine 3, see figure 2 , mainly including a DC brushless motor 31, a cutter head 32, a knife claw 33, and a support shaft 34. The tool magazine 3 is located in front of the machine tool spindle box 7, and is suspended on the tool magazine swing frame 2, and a torsion spring (not shown in the figure) is installed at the connection between the tool magazine swing frame 2 and the tool magazine support 1 . Under the action of the torsion spring, the tool magazine 3 is tightly pressed against the upper part of the guide p...

The invention discloses an automatic cutter replacing device which comprises a cutter base, a cutter hitting arm, a striking block and a guiding plate, wherein the guiding plate is fixed on a spindle box of a machine tool, and the upper portion of the guiding plate protrudes outwards compared with the lower portion; in the non-cutter-replacing state, the cutter base abuts against the upper portion of the guiding plate; a plurality of cutter claws are arranged on the cutter base, and one cutter claw is hollow. The striking block and the cutter hitting arm are installed on the other side of the spindle box, and the cutter hitting arm is fixed on the spindle box. When the cutter needs replacing, the hollow cutter claw on the cutter base is arranged on the bottommost portion. When the spindle box rises, the cutter base slides to the lower portion of the guiding plate, and the hollow cutter base enters an annular groove filled with cutters; the cutter hitting arm rises along with the spindle box, is pushed to move rightwards by the striking block, and simultaneously drives the cutters on a machine tool to move rightwards, and the cutters can be caught by the cutter claws. The spindle box rises continuously, and the cutters are drawn out by the cutter claws. Then, the cutter required by the cutter base rotates to the bottommost portion. The components move backwards to finish cutter installation. The automatic cutter replacing device can replace cutters continuously, and working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of drilling devices, in particular to a device capable of automatically replacing drilling tools. Background technique [0002] The automatic tool changer is one of the most important key components in the drilling machining center. There are two common automatic tool changers: the first one is an automatic tool changer that uses a geared motor and a separator mechanism to distribute the tools. The second is an automatic tool changing device that uses a worm screw and a flat roller cam mechanism to distribute tools. These two kinds of tool changing devices belong to the gap type tool distributing device, the rotation of the cutter head is discontinuous when changing the tool, and the rotation of one tool position and one tool position is required when the tool is selected, and the tool changing time is longer. Contents of the invention [0003] The technical problem to be solved by this invention lies in ...
