Description
Technical field
The present invention relates to a kind of on-line measuring device of band saw machine, particularly relate to a kind of band saw for metal real-time detecting device for full-distance linear velocity.
Background technology
Band saw machine is the renewal product that replaces old-fashioned hacksawing machine, is widely used in the various black nonferrous materials of sawing, and the sawing precision is high, saw kerf is little, has the characteristics such as energy-efficient, is desirable blanking equipment.Band saw for metal is the core component of band sawing machine, and closed metal saw blade that sharp teeth tough and tensile by is stretched on the driving wheel and consists of, and is used for cutting metal.In actual sawing processing, because band saw for metal is subject to differential tension in whole process different deformation can occur, its linear velocity is driving on the wheel disc along circumferentially changing.As seen, the band saw for metal linear velocity is very important sawing parameter, and it is not only directly relevant with band saw for metal each point deformation quantity, affects the service life of bands for band, also can produce larger impact to the production efficiency of band sawing machine.Therefore, development band saw for metal full-distance linear velocity detection method and device have very important significance to the dependability of research band saw machine.
Present band saw velocity measuring device mainly contains contact and contactless.Contactless linear velocity detection device, it mainly is made of sensor or approach switch, be the speed measuring device of the related a kind of belt conveyer scale of CN200820210079.0 patent such as the patent No., measure belt speed by the pulse signal that magnetosensitive approach switch produces, the contactless structure of sensor and belt, the sensor long service life is arranged, the advantages such as certainty of measurement height.In this scheme, the signal source of magnet-sensitive switch is installed on the roller carrier shaft, and roller carrier shaft directly contacts with belt again, therefore, its mechanism is slightly aobvious numerous and diverse, can't be applied to the belt speed detection without the band sawing machine of roller carrier shaft mechanism, and this scheme can only detect the belt linear velocity of ad-hoc location, is of limited application.The contact linear velocity detection device is the related a kind of ribbon conveyer band speed detector of CN101634660A patent such as patent publication No., directly contacts with belt by rubber tire, again by measuring belt speed with the coaxial mounted encoder of rubber tire.But the mechanism of mentioning in this scheme need be by on the installation of L-type cantilever beam and the frame, and whole institute of mechanism takes up space larger, and the belt speed that can't be applied to the band sawing machine of compact conformation is measured.In addition, the linear velocity that above two schemes all can only be finished ad-hoc location specified point place detects in real time, the linear velocity that but can't realize omnidistance bands for band detects in real time, also just can't satisfy the needs of the interior deformation of research closed metal bands for band global extent or load.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of real-time detecting device for full-distance linear velocity of metal band sawing machine is provided.This device by with the scaffold of the parallel installation of pulley sheaves, and the uniform multipoint mode testing agency that is installed on the framework realizes real-time detection and the feedback of whole band saw for metal linear velocity.
The technical scheme that technical solution problem of the present invention adopts is:
A kind of real-time detecting device for full-distance linear velocity of metal band sawing machine comprises scaffold and a plurality of detecting unit;
Semiorbicular scaffold places outside the pulley sheaves to be measured of band saw machine, with the coaxial setting of pulley sheaves to be measured, a plurality of detecting units is housed on the scaffold.

Screw thread has been attacked on described pillar top, and pillar top nut rotation can be regulated the distance between detecting unit and the pulley sheaves to be measured.
The invention has the beneficial effects as follows:
1, simple with existing band sawing machine mechanism assembling, less to actual sawing load effect.
2, testing agency's fast response time, inverse signal is the fiduciary level signal, is easy to subsequent treatment.
3, pass through the uniform of testing agency, be convenient to realize the saw band linear velocity measurement of band saw for metal whole process.

The specific embodiment
Below in conjunction with accompanying drawing detailed description is carried out in invention.
As shown in Figure 1, a kind of real-time detecting device for full-distance linear velocity of metal band sawing machine comprises scaffold 2 and a plurality of detecting unit, scaffold 2 and pulley sheaves 4 coaxial settings.Be evenly equipped with 20 through holes at scaffold 2, can in the process of the gyration of 3 180 ° of bands saw for metal, a plurality of detecting units be set circumferentially, each detecting unit all fits tightly with band saw for metal 3 surfaces respectively, realizes that the omnidistance of band saw for metal 3 linear velocities detects in real time.
The detection method of checkout gear: identical with the linear velocity of detecting unit roller touching position according to band saw for metal 3 surface, i.e. 2 π n
1 D=2 π n
2 d DBe the diameter of pulley sheaves 4,
dBe detecting unit roller external diameter, n

2Rotating speed for the detecting unit roller.Checkout gear is measured the rotation speed n of roller
2After, can be according to 2 π n
2 dCalculate in real time the linear velocity with the band saw for metal 3 of roller touching position.Because the deformation of band saw for metal 3 mainly occurs in its 180 ° of gyration processes, therefore only detect in real time and feedback this process is omnidistance, can realize real-time detection and the feedback of whole band saw for metal 3 linear velocities.
Shown in Fig. 2,3, detecting unit comprises roller, reflection type photoelectricity proximity switch 11, pillar 1, stage clip 6 and bearing spider 8.Roller has the bearing 7 of cushion rubber cover 9 to consist of by cover, one end of pillar 1 and bearing spider 8 are fixing, pillar 1 is equipped with stage clip 6 near bearing spider 8 positions, wheel shaft 12 is installed in the bearing spider 8, be fixed with bearing 7 on the wheel shaft 12, the side of bearing spider 8 is equipped with reflection type photoelectricity proximity switch 11, the probe of photoelectricity approach switch 11 uniform reflecting plate on cushion rubber cover (9) side.
Measure the rotation speed n of roller
2Detection method: cushion rubber on the bearing 7 cover 9 fits tightly with band saw for metal 3 surfaces, at uniform 4 reflecting plates of side of cushion rubber cover 9.Reflection type photoelectricity proximity switch 11 Emission Lasers, probe can send a pulse signal after receiving reverberation.The athletic meeting band dynamic bearing 7 of band saw for metal 3 correspondingly rolls, and in 7 every one weeks of rolling of bearing, reflection type photoelectricity proximity switch 11 can receive four secondary reflection light and send four pulse signals.One period running time
tIn, the number of counting pulse signal
n, then can extrapolate the rotating speed of bearing (7)
n 2=
n/ (4
t).
Shown in Fig. 4,5, scaffold 2 is fixed on the axle sleeve 13 by bolt 14.In order to make cushion rubber cover 9 can tightly be pressed in band saw for metal 3 surfaces, the pillar 1 that is fixed on the bearing spider 8 needs to be used with scaffold 2 and nut 5.Before the detection, pillar 1 is attacked a threaded end and is run through through hole on the scaffold 2, makes stage clip 6 between scaffold 2 and bearing spider 8, and the precession nut 5 again, the length that regulating sleeve has the bearing 7 of cushion rubber cover 9 to stretch out.After being fixed on the axle sleeve 13 by bolt 14 scaffold 2, loosen again nut 5, rely on the elastic force of stage clip 6 self, withstand bearing spider 8, thereby make cushion rubber cover 9 on the bearing 7 tightly be pressed in the surface of band saw for metal 3.
At last, the holding wire of reflection type photoelectricity proximity switch 11 is linked to each other with measuring instrument, just can measure the linear velocity of band saw for metal 3.
