Abstract
Disclosed is a detecting device for a scale shutdown mechanism, consisting of a movable base, a rotor, a rotor shaft, a sensor bracket, a sensor, a tension-spring base, a tension spring and a fin; wherein, two strip through grooves, two screwed holes used for installing the sensor frame, a screwed hole used for installing the rotor shaft and a screwed hole used for installing the tension-spring base are arranged on the movable base; the rotor is arrange on the movable base by the rotor shaft; the sensor frame is arranged on the movable base by a bolt; the sensor is arranged on the sensor frame; the tension-spring base is arranged in the screwed holes of the tension-spring base on the movable base; the tension spring is arranged between the tension-spring base and the rotor; and the fin is fixed on the rotor by a rivet.
Description
Technical field
The utility model relates to the pick-up unit of a kind of fixed ruler cutting mechanism, particularly a kind of fixed ruler cutting pick-up unit that uses on the high speed concrete-bar straightening-cutting machine.
Background technology
At present, the pick-up unit that on the high speed concrete-bar straightening-cutting machine, is used for fixed ruler cutting be a cover with the rotary encoder of coaxial friction pulley, structure as shown in Figure 1, friction pulley 1 is near the reinforcing bar in advancing, under the effect of friction force, rotate, thereby drive 2 rotations of coaxial rotary encoder light bolt.ω satisfies formula ω=1/r-ω when the accumulative total corner
0The time (in the formula: 1-cut lengths, r-friction pulley radius, ω
0-angle of advance), scrambler sends electric signal, and after control system was handled, commander's shut-off mechanism cut off reinforcing bar.
The shortcoming of this pick-up unit is: exist skidding between friction pulley and the reinforcing bar (particularly Ribbed Bar), and unstable, so the testing result deviation is bigger, actual scale error often 〉=± 20mm.And along with the radius r of friction pulley reduces because of wearing and tearing gradually, the scale error can be increasing.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of pick-up unit that is used for fixed ruler cutting on the high speed concrete-bar straightening-cutting machine is provided.
The technical solution of the utility model is: the pick-up unit of a kind of fixed ruler cutting mechanism, it is made up of mobile seat, rotor, armature spindle, sensor stand, sensor, extension spring seat, extension spring and fin.Be used for the threaded hole of sensor installation support, a threaded hole and a threaded hole that is used for installing the extension spring seat that is used for installing armature spindle moving the groove that is provided with two strips on the seat, two.Rotor is installed in by armature spindle and moves on the seat, sensor stand is installed in by screw and moves on the seat, and sensor is installed on the sensor stand, and the extension spring seat is installed in the extension spring seat threaded hole that moves on the seat, extension spring is located between extension spring seat and the rotor, and fin is fixed on the rotor by rivet.
During use, pick-up unit is installed on the appropriate location of unloading rack, can meticulous adjustment pick-up unit position, front and back by the groove that moves two strips on the seat.During concrete-bar straightening-cutting machine work, the epitrochanterian fin of its head impact of reinforcing bar to be cut, and it is backed down, therefore rotor rotates an angle, the catch on rotor top forwards under the detecting head of position transducer, sensor sends electric signal at once, and this signal indicates shut-off mechanism to cut off reinforcing bar after MICROCOMPUTER PROCESSING immediately.
The utility model compared with prior art has following characteristics: this device reaction is rapid, the repeatable accuracy height, through test proof in enormous quantities, the scale error can be controlled at ± 3mm within, precision than the rotation coder structure exceeds several times, and cost has only the former 1/tens.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
