Abstract

The utility model relates to the technical field of CNC machining centers, in particular to a CNC machining tool changing device. Technical problem current tool changing device, when carrying out the tool changing, operating procedure is comparatively loaded down with trivial details, leads to the inefficiency of tool changing to the cutter that the tool changing was down often attached to cutting piece etc. and current tool changing device is inconvenient to clean the cutter that the tool was down, leads to remaining smear metal and scale deposit can accelerate cutter wearing and tearing, influences cutting edge sharpness, shortens cutter life. A CNC machining tool changing device comprises a mounting plate and two guide rails fixedly connected to the mounting plate. When rotating frame switches the cutter, the upper and lower both ends of cutter can be with double-deck brush contact, stir the frame pivoted simultaneously and can promote double-deck brush removal repeatedly, make double-deck brush reciprocating motion under the effect of first compression spring and second compression spring, and then brush the cutter both ends that get off and wipe, and then get rid of the metal fillings that adhere on the cutter to the life of extension cutter.

Description

CNC processing tool changing device Technical Field The utility model relates to the technical field of CNC machining centers, in particular to a CNC machining tool changing device. Background In CNC machining process, need frequent change cutter to this satisfies different processing demands, when changing the sword, uses the manipulator to change the sword generally, snatchs and exchanges the cutter, reaches the purpose of changing the sword. Because when CNC processing, cutter quantity is more, and current tool changing device, when carrying out the tool changing, operation procedure is comparatively loaded down with trivial details, leads to the inefficiency of tool changing to the cutter of changing often adheres to cutting chip, coolant liquid and remains or processing material scale deposit, and current tool changing device is inconvenient to clean the cutter of changing down, leads to remaining smear metal and scale deposit can accelerate cutter wearing and tearing, influences cutting edge sharpness, shortens cutter life-span. Disclosure of utility model In order to overcome the defects, the utility model provides the CNC machining tool changing device which can quickly complete the switching of the tools so as to improve the tool changing efficiency and clear the replaced tools and prolong the service life of the tools. The technical scheme is that the CNC machining tool changing device comprises: A mounting plate; Two guide rails fixedly connected to the mounting plate; The electric sliding blocks are respectively connected to the two guide rails in a sliding manner; the tool magazine with the notch is fixedly connected to the electric slide block; the switching assembly is arranged on the tool magazine; eight groups of clamping components arranged on the rotating frame; and the cleaning assembly is arranged on the tool magazine. Further, the switching assembly comprises a servo motor fixedly connected to the tool magazine and a rotating frame fixedly connected to an output shaft of the servo motor. Further, each clamping assembly comprises two clamping jaws and a torsion spring, the two clamping jaws are symmetrically arranged and are both rotationally connected with the rotating frame, and the torsion springs are connected between the two clamping jaws and the rotating frame. Further, a cutter is clamped on one group of clamping assemblies. The cleaning assembly further comprises a rotating column fixedly connected to the rotating frame, a poking frame connected to the rotating column in a sliding mode, a first compression spring connected between the poking frame and the rotating column, an extrusion block fixedly connected to the inner wall of the tool magazine, an arc-shaped rod fixedly connected to the inner wall of the tool magazine, a double-layer brush connected to the arc-shaped rod in a sliding mode, and a second compression spring connected between the double-layer brush and the arc-shaped rod. The cutter changing device has the beneficial effects that 1, when a cutter is clamped between the clamping jaws, the clamping jaws clamp the cutter to be changed under the action of the torsion spring, then a worker controls the cutter shaft to loosen the cutter, then the worker controls the output shaft of the servo motor to rotate, the rotation of the output shaft of the servo motor drives the cutter to be changed to rotate through the rotating frame, the rotating angle of the servo motor is controlled to correspond to the cutter shaft according to the number of the cutter to be changed, the cutter shaft is connected with the cutter, and then the cutter changing is completed, so that the cutter changing is faster and more accurate, and the cutter changing efficiency is improved. 2. When rotating frame switches the cutter, the upper and lower both ends of cutter can be with double-deck brush contact, stir the frame pivoted simultaneously and can promote double-deck brush removal repeatedly, make double-deck brush reciprocating motion under the effect of first compression spring and second compression spring, and then brush the cutter both ends that get off and wipe, and then get rid of the metal fillings that adhere on the cutter to the life of extension cutter.
