Description
Technical field
The utility model relates to a kind of clock and watch part processing equipment, is specifically related to a kind of tapping machine of processing watch making thread.
Background technology
Clock and watch are metering and the precision instrument of instruction time, and there are the parts such as the gear of many precisions and bolt and nut its inside.In clock and watch, the size of each parts is less, and for example the general diameter of bolt is at 0.6～1mm, and screw aperture is correspondingly also less, and in process of production, the tapping step of these small-bore screws often need to be utilized tapping machine to complete by skilled operating personnel.
Conventional tapping machine is when workpiece loading and unloading, and the screw tap that main shaft drives and the workpiece of processing need to keep certain safe distance (being generally 3-5cm), is beneficial to operating personnel's operation; And in tapping process, because the size of screw is less, the screw tap of main shaft bottom and workpiece only need contact the shorter time (the general 1-3mm of thickness of workpiece) and can complete tapping operation, thereby each screw tap is far longer than the tapping time by the spent time of safe distance, if can shorten the spent time of this LAP, the operating efficiency of tapping machine can further improve.
Utility model content
The technical problems to be solved in the utility model is the deficiency that overcomes above-mentioned background technology, and a kind of tapping machine is provided, and this tapping machine should have operating efficiency feature high, easy to operate, simple in structure.
The technical solution adopted in the utility model is: a kind of tapping machine, comprise base, be fixed on base top surface column, be fixed on the mounting platform of column upper end, be vertically arranged on main shaft on mounting platform and the drive motors of main shaft, the lower end of main shaft is provided with screw tap, on the base of screw tap below, work piece holder is installed, it is characterized in that: on the main shaft in described mounting platform, be fixed with two baffle rings, between two baffle rings, be provided with a loose collar, between loose collar and the baffle ring of downside, be provided with stage clip; The interior also hinged driving lever of mounting platform, the shift fork of the driving lever other end stretches between loose collar and the baffle ring of upside, one extension spring applies pulling force upward to driving lever, separately be provided with electromagnet and a travel switch toward below absorption driving lever, described travel switch and electromagnet, start button and relay are connected to form the control circuit of electromagnet.
The control circuit of described electromagnet comprises two branch roads in parallel; Article one, in branch road, electromagnet is connected with first group of normally opened contact of relay; In second branch road, second group of normally opened contact of the coil of relay, relay and the series connection of the normally-closed contact of travel switch, start button is connected in parallel on second group of normally opened contact two ends of relay.
Described driving lever is fixed with the magnetic block corresponding with electromagnet.
The control circuit of described electromagnet comprises two branch roads in parallel; Article one, in branch road, electromagnet is connected with first group of normally opened contact of relay; In second branch road, second group of normally opened contact of the coil of relay, relay and the series connection of the normally-closed contact of travel switch, start button is connected in parallel on second group of normally opened contact two ends of relay.
Operation principle of the present utility model is: press start button, main shaft forward, the coil of relay obtains electric, and first group of normally opened contact is closed, electromagnet obtains and electric driving lever is adsorbed downwards, driving lever is depressed loose collar, at the effect lower main axis drive screw tap fast-descending of stage clip, after electromagnetic actuation puts in place, stage clip continues to press down a bit of distance by main shaft, complete tapping operation (in this stage, second group of normally opened contact is closed, realizes circuit self-locking after start button resets);
Electromagnetic actuation puts in place, stage clip promotes main shaft and declines until the baffle ring of downside is encountered after travel switch, the normally-closed contact of travel switch is opened, the coil blackout of relay, first group of normally opened contact recovers open mode, electromagnet power-off and main shaft reversion, driving lever drives main shaft fast rise to reset under the effect of extension spring; Second group of normally opened contact recovers open mode, waits for next operation.
The beneficial effects of the utility model are: the utility model utilizes electromagnet that main shaft is fallen fast, utilize extension spring to make main shaft depart from fast workpiece, the time of expending in the time of can significantly saving tapping, effectively increase work efficiency, operate also more convenient, also there is feature simple in structure, with low cost.
