Abstract
The invention discloses a laser measuring device for positioning a wheel, which consists of a laser straight-line beam generator, a central shaft and a fixed disk, wherein one end of the central shaft is vertically connected with the center of the fixed disk; the laser straight-line beam generator is connected with the other end of the central shaft; an emitted direction of a laser beam is vertical to an axial direction of the central shaft; a side of the central shaft is connected with a suspended support of which the upper end is provided with two suspension arms at intervals; the fixed disk is connected with three measuring arms through hinge pins; each of the measuring arms is provided with a chute; a distance measuring block is respectively arranged in each of the chutes; and adjusting screws are arranged between the distance measuring blocks and the measuring arms. The laser straight-line beam generator, the central shaft and the fixed disk are fixed by the suspension support, and a circle center is positioned by the three measuring arms and distance measuring blocks, so that the actual states of the camber angle, the inward inclination angle and the toe-in of a hub-deformed wheel can be accurately measured.
Description
Technical field:
The present invention relates to physical field, relate in particular to measuring technique, particularly wheel positioning device, concrete is a kind of laser measuring device for measuring that is used for wheel alignment.
Background technology:
The part vehicle in use, the camber angle of wheel, leaning angle and toe-in can change, and cause running out the way, the unbalanced wearing and tearing of tire.In the prior art, adopt laser measuring device for measuring that the inclination situation of wheel is amplified, cooperate, can accurately measure camber angle, leaning angle and toe-in with Magnetic Measurement chi, turning radius dip stick, prenex dip stick, electric slope angle instrument, and under the guiding of above-mentioned measurement mechanism, finish and repair and adjust.Laser measuring device for measuring is made of a laser rectilinear light beam generator, a central shaft and a three-jaw shaft collar, central shaft is vertically connected on the center of three-jaw shaft collar, laser rectilinear light beam generator is connected the other end of central shaft, the ejaculation direction of laser beam is axial perpendicular to central shaft, after the wheel shell of three-jaw shaft collar and wheel is fixing, rotary laser rectilinear light beam generator on central shaft, the wheel shell plane parallel through plane and wheel of laser beam, thus camber angle, leaning angle and prenex virtual condition reflected.But there is distortion in the wheel shell of part vehicle, when therefore adopting said apparatus to measure error can take place.
Summary of the invention:
The purpose of this invention is to provide a kind of laser measuring device for measuring that is used for wheel alignment, the described this laser measuring device for measuring that is used for wheel alignment will solve the technical matters that prior art laser wheel alignment meter is not suitable for taking turns the wheel alignment of shell distortion.
This laser measuring device for measuring of wheel alignment that is used for of the present invention is by a laser rectilinear light beam generator, a central shaft and a shaft collar constitute, one end of described central shaft is vertically connected on the center of shaft collar, described laser rectilinear light beam generator is connected the other end of central shaft, the ejaculation direction of laser beam is axial perpendicular to central shaft, wherein, the side of described central shaft is connected with a suspension holdfast, the upper end of described suspension holdfast is arranged at intervals with two cantilevers, be connected with three gage beams by bearing pin on the described shaft collar, be provided with chute in any one described gage beam, be provided with a range observation piece in any one described chute, be provided with the adjustment screw between described range observation piece and the gage beam.
Further, be provided with protruding thorn in the bottom side of described cantilever.
