Description
Technical field
The utility model relates to a kind of electric drill of carrying magnetic seat, belongs to the electric tool technical field.
Background technology
Motor, transmission mechanism, main shaft, control circuit and manual delivering gear etc. are installed on support, frame and the frame of existing magnetic drill press by charged magnet to be constituted.Manually delivering gear is made up of gear, tooth bar and the control stick that is connected on the gear.Hole and add man-hour, must be by artificial rotation manual control stick, apply downward pressure and carry out drilling processing, owing to be artificial feeding processing, the aperture surface that processes is very coarse during drilling, and precision is not high, working depth also is difficult to accurately control, influence boring crudy, and operator's labour intensity is big, inefficiency.Moving back when boring, is that triangle contract iron moves back drill bit because magnetic drill press adopts, formation be oblique extruding force, make and move back that to bore difficulty big, waste time and energy, and need have triangle contract iron at any time, extremely inconvenient.So, realize that the magnetic drill press autofeed carries out drilling processing, be the problem that the long-term endeavour of magnetic drill press industry solves always.Because, it is little that magnetic support is drilled with volume, in light weight, the requirement of being convenient to go out to carry and directly on large-scale workpiece, processing, so, before this, though people have done a large amount of effort, go out a kind of magnetic drill press of the practical autofeed of being satisfied with and fail development and production, at present, the widely used magnetic drill press that remains manual delivering gear.
The utility model content
The purpose of this utility model is exactly the deficiency that exists at existing magnetic drill press, improves, and provides a kind of volume little, in light weight, autofeed formula magnetic drill press easy to use.
The purpose of this utility model is to realize like this, autofeed formula magnetic drill press, comprise motor, transmission mechanism, main shaft, the control circuit installed on support, frame and the frame of charged magnet, it is characterized in that magnetic drill press is provided with auto-feed transmission mechanism and travel control switch, the armature spindle of motor is connected with spindle drive by the auto-feed transmission mechanism, and travel control switch connects control circuit.The motor of installing on described frame and the frame, transmission mechanism, control circuit are arranged in the casing.The auto-feed transmission mechanism is input gear, feed gear, travelling gear to be set on the splined shaft and differential gear, output gear are installed on thread spindle, and being meshing with each other to connect through gear constitutes.Described travelling gear and splined shaft sliding connection, the feed gear is fixedlyed connected with splined shaft.Described output gear is threaded with thread spindle, and differential gear is fixedlyed connected with thread spindle.Described main shaft is a hollow shaft, at the hypomere of hollow axis hole drill bit is installed, and epimere is installed striker, and the top of striker is provided with stop.Described travel control switch is separately positioned on the upper and lower of output gear.
In drive disk assembly, by motor by the one-level change-speed gearing with transmission of power to splined shaft.On splined shaft, be provided with two gears, a travelling gear on splined shaft, sliding, another is and the fixing feed gear of splined shaft.On the one hand, by slidable travelling gear, with the output gear of transmission of power to the thread spindle, output gear and thread spindle be by threaded engagement, again by output gear with transmission of power to main shaft, main shaft is done gyration; On the other hand, by with the fixing feed gear of splined shaft, be meshed with differential gear on the thread spindle, drive thread spindle and rotate, and then the output gear crop rotation of drive and thread spindle threaded engagement is risen or the motion of decline, does reseting movement upwards or downward feed campaign thereby drive main shaft.
Use autofeed formula magnetic drill press to hole and add man-hour, earlier drill bit is clamped in the hollow axis hole of main shaft, and gear shifting handle placed at a slow speed or high gear, magnetic drill press is placed on the fixing pedestal, aim at position to be processed, open the magnet base power switch, magnet base is sucked on basal plane, prop up good support bar, assurance autofeed formula magnetic drill press is holed and is added the stable of man-hour.Open motor switch again, starter motor, by armature spindle transmission of power is arrived the input gear, splined shaft begins to rotate, travelling gear and feed gear begin to rotate simultaneously, on the one hand, travelling gear drives output gear and rotates, and output gear to main shaft, drives transmission of power cutter and does gyration work, on the other hand, to differential gear, differential gear drives thread spindle and does gyration the feed gear with transmission of power, and thread spindle drives output gear again, main shaft and travelling gear are done downward feed motion together, promptly finish the action of feed, beginning automatic drilling cutwork.The pointer that drives in the main shaft decline process on the dial rotates, by the degree of depth that can read feeding of the pointer on the dial.
In transmission mechanism, be provided with travel switch, just changeing and adding man-hour, adjusting the position of travel switch, after drill bit goes downwards to the degree of depth of regulation, contact travel switch, just connect reverse turn control circuit, drill bit is auto-reverse and do motion upwards, when drill bit returns to original position, to contact another travel switch, just automatic shutdown circuit, motor stops operating, and realizes processing and the autofeed function that resets.
When bit change more, only need to start move back the brill button, main shaft is done motion upwards, and the drill bit in the main shaft contacts the striker that is installed in the hollow shaft, and drill bit is ejected main shaft, moves back brill automatically.
The utility model compactness rational in infrastructure is manufactured easily, and volume is little, and is in light weight, be easy to carry, use easy to operately, reduce operator's labour intensity, improve labor productivity, the automatic controlling level height has guaranteed the degree of depth and precision that boring is cut, improves the crudy of product.
