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 characteristics such as energy-efficient, is desirable blanking equipment.Band saw for metal is the core part of band sawing machine, and with closed metal saw blade that sharp teeth be stretched in driving wheel on tough and tensile by constitutes, and is used for cutting metal.In actual sawing processing, because band saw for metal receives differential tension in whole process different deformation can take place, its linear velocity circumferentially can change in driving wheel disc upper edge.It is thus clear that the band saw for metal linear velocity is very important sawing parameter, it is not only directly relevant with band saw for metal each point deformation quantity, influences the service life of bands for band, also can produce bigger influence to the production efficiency of band sawing machine.Therefore, omnidistance linear velocity detection method of development band saw for metal 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 constitutes by sensor or near switch; Like the patent No. is the speed measuring device of the related a kind of belt conveyer scale of CN200820210079.0 patent, measures belt speed, the contactless structure of sensor and belt through magnetosensitive near the pulse signal that switch produces; The sensor long service life is arranged, advantages such as certainty of measurement height.In this scheme, the signal source of magnetosensitive switch is installed on the roller carrier shaft, and roller carrier shaft directly contacts with belt again; Therefore, it is numerous and diverse that its mechanism shows slightly, and the belt speed that can't be applied to not have the band sawing machine of roller carrier shaft mechanism detects; 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 belt speed checkout gear of CN101634660A patent like patent publication No., directly contacts with belt through 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 through on installation of L type cantilever beam and the frame, and whole institute of mechanism takes up space bigger, and the belt speed that can't be applied to the band sawing machine of compact conformation is measured.In addition; More than the linear velocity that all can only accomplish ad-hoc location specified point place of two kinds of schemes detect in real time; The linear velocity that but can't realize omnidistance bands for band detects in real time, also just can't satisfy deformation or the big or small needs of load in the research closed metal bands for band global extent.
Summary of the invention
The utility model provides a kind of band saw machine omnidistance linear velocity real-time detection apparatus to the deficiency of prior art.This device through with the scaffold of the parallel installation of pulley sheaves, and be uniformly distributed with the multipoint mode testing agency that is installed on the framework, realize the real-time detection and the feedback of whole band saw for metal linear velocity.
The technical scheme that the utility model technical solution problem is adopted is:
The omnidistance linear velocity real-time detection apparatus of band saw 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, the distance between pillar top nut rotation scalable detecting unit and the pulley sheaves to be measured.
The beneficial effect of the utility model is:
1, simple with existing band sawing machine mechanism assembling, less to actual sawing load effect.
2, testing agency's response speed is fast, and inverse signal is the fiduciary level signal, is easy to subsequent treatment.
3,, be convenient to realize that the omnidistance saw band linear velocity of band saw for metal measures through being uniformly distributed with of testing agency.

The specific embodiment
Below in conjunction with accompanying drawing utility model is carried out detailed description.
As shown in Figure 1, the omnidistance linear velocity real-time detection apparatus of band saw machine comprises scaffold 2 and a plurality of detecting units, scaffold 2 and pulley sheaves 4 coaxial settings.On scaffold 2, be evenly equipped with 20 through holes; 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 according to band saw for metal 3 surface with the linear velocity of detecting unit roller touching position, 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
1Be the rotating speed of pulley sheaves 4, 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 linear velocity in real time 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 the real-time detection and the feedback of whole band saw for metal 3 linear velocities.
Like Fig. 2, shown in 3, detecting unit comprises that roller, reflective photoelectricity are near switch 11, pillar 1, stage clip 6 and bearing spider 8.Roller is made up of the bearing 7 that is with cushion rubber cover 9; One end of pillar 1 and bearing spider 8 are fixing; Pillar 1 is equipped with stage clip 6 near bearing spider 8 positions, and wheel shaft 12 is installed in the bearing spider 8, is fixed with bearing 7 on the wheel shaft 12; The side of bearing spider 8 is equipped with reflective photoelectricity near switch 11, the reflecting plate that photoelectricity is uniformly distributed with on cushion rubber cover (9) side near the probe of switch 11.
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, is uniformly distributed with 4 reflecting plates at the side of cushion rubber cover 9.Reflective photoelectricity is near switch 11 emission laser, and probe can send a pulse signal after receiving reverberation.The athletic meeting of band saw for metal 3 drives bearing 7 and correspondingly rolls, and in 7 every one weeks of rolling of bearing, reflective photoelectricity can receive four secondary reflection light and send four pulse signals near switch 11.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).
Like Fig. 4, shown in 5, scaffold 2 is fixed on the axle sleeve 13 through 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 the through hole on the scaffold 2, makes stage clip 6 between scaffold 2 and bearing spider 8, and the precession nut 5 again, regulates the length that the bearing 7 be with cushion rubber cover 9 stretches out.After being fixed on the axle sleeve 13 through bolt 14 scaffold 2, loosen nut 5 again, 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 reflective photoelectricity near switch 11 linked to each other with measuring instrument, just can measure the linear velocity of band saw for metal 3.
