Abstract
The invention discloses a belt slip detecting device on a punching machine. The device comprises a flywheel, and a belt wheel coaxially and fixedly connected to an output shaft of a motor; and the belt wheel and the flywheel are in transmission through a belt. The device is characterized in that a large gear is coaxially fixed on the flywheel; the punching machine is coupled with a small gear; the small gear is engaged with the large gear; the small gear is coaxially fixed with an encoder; and the ratio of the outer diameter of the flywheel to the outer diameter of the belt wheel is equal to the ratio of the pitch diameter of the large gear to the pitch diameter of the small gear. The device has the following advantages: when the punching machine works, the detecting device detects the rotating angles of the belt wheel and the flywheel in real time to judge if the belt slips; and a control system of the punching machine can timely respond when the belt slips, so that such equipment as the belt and the punching machine and the personal safety are preferably protected.
Description
Technical field
The present invention relates to punch press, particularly relate to the belt skidding detecting device on a kind of punch press.
Background technology
In the punching production process of punch press, in order to prevent because slipping of belt causes abrasion or the damage of belt, even there is security incident, belt skidding detecting device is often installed in punch press. Whether current belt skidding detecting device by the pulse signal quantity of detection belt pulley and flywheel proximity switch within for some time, and can only exceed predetermined scope according to the ratio of both pulse signal quantity and judges whether belt exception of skidding occurs. But this kind of detection mode existing defects, it needs just can judge whether to skid by the detection of for some time, and in this period, belt is also caused damage by a segment distance that actual skidding has produced quite to grow, and therefore, whether it can not skid by real-time judge belt, the demand of actual production detection cannot be met, the damage of mould, punch press may be caused because detection is incured loss through delay, even jeopardize the personnel safety of operator, there is potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of skidding situation that can detect belt in real time, with the belt skidding detecting device on the punch press better protecting the equipment such as belt, punch press and personal security.
The present invention solves the problems of the technologies described above the technical scheme adopted: the belt skidding detecting device on a kind of punch press, the belt pulley comprising flywheel and be coaxially fixedly connected on the output shaft of motor, belt transmission is passed through between described belt pulley and described flywheel, described flywheel is coaxially fixedly installed master wheel, punch press is connected with pinion(gear), described pinion(gear) is meshed with described master wheel, described pinion(gear) is coaxially fixedly installed encoder, the external diameter of described flywheel equals the described pitch circle diameter of master wheel and the ratio of the pitch circle diameter of described pinion(gear) with the ratio of the external diameter of described belt pulley.
Being fixedly installed bearing support on described punch press, described pinion(gear) is arranged on described bearing support by transmission shaft, and described transmission shaft is coaxially fixedly connected with described encoder by shaft coupling.
Compared with prior art; it is an advantage of the invention that when punch press works; the skidding that the angle of rotation detecting belt pulley and flywheel in real time by this detection device judges belt is whether; and can be made a response in time when slipping of belt occurs by the Controlling System of punch press, protect the equipment such as belt, punch press and personal security better.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the enlarged diagram at A place in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in the figure, belt skidding detecting device on a kind of punch press, the belt pulley 3 comprising flywheel 1 and be coaxially fixedly connected on the output shaft of motor 2, by belt 4 transmission between belt pulley 3 and flywheel 1, flywheel 1 is coaxially fixedly installed master wheel 5, punch press is fixedly installed bearing support 6, bearing support 6 is provided with pinion(gear) 7 by transmission shaft (not shown), pinion(gear) 7 is meshed with master wheel 5, transmission shaft (not shown) is coaxially fixedly connected with encoder 9 by shaft coupling 8, the external diameter of flywheel 1 equals the ratio of the pitch circle diameter of master wheel 5 with the pitch circle diameter of pinion(gear) 7 with the ratio of the external diameter of belt pulley 3.
In above-described embodiment; this belt skidding detecting device realizes the process of detection: owing to belt 4 exists Elastic Sliding in actual transmission process; there is certain error in the angle indicated by encoder that encoder 9 and motor 2 carry; therefore; the Controlling System of punch press arranges certain limit of error and avoids flase alarm; when the angle that the encoder that encoder 9 and motor 2 carry is indicated exceeds limit of error; Controlling System judges slipping of belt, and controls motor 2 and stop work and other a series of sfgd..
