Problems solved by technology
However, at present, there are tens of millions of ordinary drilling machines owned by domestic small and medium-sized enterprises, factories and small processing workshops. This type of ordinary drilling machine has a low level of automation technology, relatively low processing accuracy, requires more labor during the processing process, and has low production efficiency. , mainly used for small batch production or single piece production
Usually in the process of processing, if the workpiece is too thick or the chip removal of the tool is not smooth, the rotation speed of the tool will be reduced, the attack will be difficult, or even stuck, and the tool head will be broken. Therefore, there must be an operator monitoring and Adjust operations in time
Therefore, this type of machine tool wastes a lot of manpower, material resources and financial resources, but if these equipments that have not yet reached their service life are eliminated, a lot of resources will be wasted

Abstract
The invention discloses a control system and method for preventing an ordinary drilling machine from getting stuck. The control system for preventing the ordinary drilling machine from getting stuck comprises a Hall sensor, a triode pulse signal amplifier, an AT89C51 single-chip microcomputer, a comparator, a signal processor, a solid-state relay, a three-phase asynchronous motor, a main shaft gearbox, a main shaft feeding box, a main shaft, an LED displayer, a buzzer, a watchdog and the like, wherein the Hall sensor acquires a pulse signal through the main shaft and a main shaft box, the pulse signal is amplified through the triode pulse signal amplifier and then is transmitted to the AT89C51 single-chip microcomputer to be calculated, so that a rotating speed signal is obtained, the comparator compares the rotating speed signal with the a preset valve, a comparison result is shaped through the signal processor and then is transmitted to the solid-state relay, and then a forward-rotation signal or a reverse-rotation signal is generated. According to the control system for preventing the ordinary drilling machine from getting stuck, automation improvement on the ordinary drilling machine is achieved through an electrical control element, the structure is simple, cost is low, the problem that the ordinary drilling machine gets stuck easily when the ordinary drilling machine is used for drilling is solved, the production efficiency is high, the safety performance is high, and the control system and method are suitable for equipment such as radial drills and vertical drills used for hole machining in the machine manufacturing industry.
Description
technical field [0001] The invention relates to a common drilling machine control device, in particular to an anti-jamming braking system and a method thereof for a common drilling machine. Background technique [0002] Ordinary radial drilling machines, vertical drills, etc. are machine tools that use drills to process holes in workpieces. Usually the drill bit rotates as the main movement, and the axial movement of the drill bit is the feed movement. The machining accuracy is relatively low. It can drill through holes, blind holes, replace special tools, and can be reamed, countersinked, reamed, or tapped. During the machining process, the workpiece does not move, let the tool rotate and move longitudinally, and the center of the tool is aligned with the hole machining center. As a general-purpose equipment for mechanical processing, drilling machines have always played an irreplaceable role in the machinery manufacturing industry, and have become the main equipment in mo...
