Description
The utility model relates to a kind of Thicknesser probe, and relating in particular to a kind of being used for inductosyn is the online dynamic Thicknesser probe of sensor.
Thicknesser probe is the critical component of on-line dynamic measurement product thickness, and the measurement of product thickness relates to production fields such as rubber, plastics, weaving, papermaking, sheet metal, and along with high-tech development, requires the thickness measuring precision just higher.Utilize inductosyn also many at present as the product of sensor preparation Thicknesser probe; generally the variation of measured object thickness is converted to the variation of probe displacement by Thicknesser probe; and utilize inductosyn that the high resolving power (can reach micron order) of displacement measurement is realized that the high precision thickness measuring measures; but because this body structure of Thicknesser probe is unreasonable; often do not reach required measurement high precision; in addition; when measured object thickness is excessive; itself do not protect structure because of popping one's head in; probe is damaged, so can not satisfy the demand of production field.
The purpose of this utility model is to provide a kind of high-precision Thicknesser probe with super thickness measuring protective device, and realizing high-acruracy survey in the thickness measuring application, and usable range is wide, long service life.
The purpose of this utility model is to realize like this, a kind of Thicknesser probe includes housing, is arranged at the forward and backward axle bed in the housing, decide grillage, be linked to the inductosyn stator of deciding on the grillage with axle bed bottom, front and back is connected, the moving grillage that is connected with the front and back axle bed is arranged at the inductosyn moving plate on the moving grillage, moving turning rolls, moving roller, decide turning rolls, decide roller, it is characterized in that:
Move, decide roller and be the solid wheel that two has axle, it respectively is arranged in moving, as the to decide turning rolls bearing seat, and is moving, decide turning rolls and be made up of upper and lower plate two parts, and the frame that rolls surely is fixedly arranged on the fixture, moving turning rolls is linked on the moving grillage, which is provided with jackscrew; Moving grillage two ends and centre are provided with three bearings altogether; with with moving plate on set three axles serve as that the guiding of rolling moves and cooperates; moving grillage middle part is connected with the optical axis cover by joint; before the optical axis cover is arranged at; in two arms of back axle bed; and be arranged at the connection of rolling mutually of the linear bearing at optical axis two ends and ball in the set ball rack of two arm ends by it; be provided with a back plug at the back axle bed other end; in the plug of back, be provided with the jackscrew of a spring base and regulating spring power; spring freely is arranged in the cover of optical axis cover; the one end is fixed on the spring base; the inner side end of the other end and joint is inconsistent; deciding to be provided with a moving super thickness measuring protective device of roller on the grillage; this device is by being arranged at the excentric shaft of deciding on the grillage; screw rod on the excentric shaft is set; off-centre is located at the hook on this and is arranged at the hook plate on the connection seat and blocks the clutch shaft of establishing mutually with hook plate with linking up with hook and forms; clutch shaft is arranged in the rolling bearing at connection seat two ends; and with decide grillage and be connected; on connection seat, be provided with a spring case; one end and the box of box medi-spring are connected; the other end and centrifugal shaft are connected; the hook lower end is a hook; the middle part be provided with one with the eccentric hole that is provided with of excentric shaft; top is a push rod; this push rod; on the center line of screw rod and the moving turning rolls the center line of fixed jackscrew all in same plane, the motion of jackscrew follower rollers can touch screw rod and rotate around excentric shaft.
The Thicknesser probe of said structure is because of moving; it is moving to decide roller and its; decide between turning rolls; between moving grillage and moving plate; moving grillage with before; the rolling that being dynamically connected between back axle bed all adopted rolling bearing connects; therefore friction force is little; guidance quality is good; make this Thicknesser probe than general Thicknesser probe degree of accuracy height; abrasion is little and the life-span is long; above-mentioned in addition super thickness measuring protective device is super when thick at measured object; the screw rod that jackscrew contacts on the excentric shaft makes it rotate around excentric shaft; owing between eccentric rotation back excentric shaft and the hook hole gap is arranged; make excentric shaft contact disengaging with hook; hook is just unclamped with hook plate; under spring force and the action of gravity of probe own, whole probe is rotated to counter-clockwise direction around clutch shaft; thereby making roller is that super thick measured object gives way, and makes roller and the whole probe can be because of super thick damaged.
The advantage of this Thicknesser probe is:
1, measuring accuracy height, precision can reach 0.01mm.
2, probe is roller type, it can be according to measured object size, the different probe size shape of selecting, so it is applied widely, this probe also can install to level, vertical, vergence direction and carry out multi-faceted measurement in addition, and when measurement needs multiple spot, then can adopt a plurality of spy points and realize multimetering, thereby usable range is wide.
3, because of being provided with the adjustable pressure regulation jackscrew of pressure measurement amount, the pressure measurement wide ranges can reach 25-200g, and also can strengthen in special requirement.
4, the thickness measuring scope is big, can reach 0-10mm, and special requirement also can strengthen.
5, match with any kind of inductosyn digital display meter, can form high precision, multifunctional intelligent thicknessmeter.
With embodiment and accompanying drawing structure of the present utility model is further narrated below.
