A deburring device for tachometer injection shell

Abstract

The invention discloses a deburring device for machining an injection molding shell of a tachometer. The deburring device comprises a machining table, the supporting rods are fixedly mounted at the four corners of the top end of the machining table correspondingly, and a supporting plate is fixedly connected among the top ends of the four supporting rods; a vertically-arranged first servo electricpush rod is rotationally installed on the supporting plate, an output shaft of the first servo electric push rod is vertically downward and is fixedly connected with a horizontally-arranged installing plate, the bottom end of the installing plate is slidably connected with an adjusting box, and the side, away from the adjusting box, of the bottom end of the installing plate is fixedly connected with a vertically-arranged fixing plate. The deburring device is ingenious in structure and is convenient to use, the distance between the two grinding wheels and the horizontal positions of the two grinding wheels both can be adjusted, the device can be used for polishing and deburring the injection molding shells of the tachometers with different diameters and different wall thicknesses, the application range of the device is wider, the two grinding wheels can be driven by just one driving motor, and the device is more energy-saving and environment-friendly, is more efficient and can reduce the production cost effectively.

Description

technical field [0001] The invention belongs to the field of tachometers, and in particular relates to a deburring device for an injection molded shell of a tachometer. Background technique [0002] The parts of the tachometer are generally installed in the plastic casing through injection molding. The plastic casing has a cylindrical shell structure. One side of the plastic casing is used to fix the round glass, and the inside of the plastic casing is used to install various components. Plastic When the shell is produced, it is molded once by an extruder and a mold. The side where the round glass is installed on the formed plastic shell has burrs because the extruder squeezes a small amount of plastic fluid into the injection mold during injection molding. These burrs In the prior art, it is generally removed by manual use of a file in the later stage. This processing method is extremely inefficient and consumes a lot of manpower and time.
