Description

Automobile turntable

The utility model relates to a kind of vehicle inspection and test auxiliary device, particularly relates to a kind of Automobile turntable.

In order to guarantee the safety of automobile night running, car headlamp is except must having enough illumination, and light-beam position also has exacting requirements, according to G B 7258-97 " self-propelled vehicle safe in operation engineering factor " relevant regulations, 10 meters apart from the time, the left and right side-play amount of dipped beam is≤100mm; Distance light left side lamp left avertence≤100mm, right avertence≤170mm; Left and right equal≤the 170mm partially of right lamp.But because automobile is when detecting on detection line, the longitudinal centerline of automobile often can not with the driving central lines on the detection line, promptly can not satisfy the pacing factor that detects the car headlamp light-beam position, therefore, make the car headlamp beam detection lose meaning.At present, both at home and abroad detection line is equipped with and can bears axle loaden mass less than 1 ton miniature car straight-putting unit.It is by cylinder or cylinder pushes baffle plate, promote tested automotive wheel from the outside, wheel is slided on steel plate, make the driving central lines on automobile longitudinal line of centers and the detection line at last, and axle loaden mass is big owing to quality greater than 1 ton automobile, then can not use this straight-putting unit to ajust, also just can't accurately detect the headlight beam position.

The purpose of this utility model is to provide a kind of can make the tested automobile longitudinal line of centers of any axle loaden mass and the Automobile turntable of detection line up train central lines.

The utility model Automobile turntable is achieved in that it by preceding shaft platform, forms forward and backward flat-bed central lines with the cooresponding back of preceding shaft platform shaft platform.Preceding shaft platform comprises front frame, a plurality of translation rollers are installed on it and with the line of centers be axis of symmetry be symmetrically distributed two before shifting boards, the translation roller rolls with front frame and cooperates, be connected on the front frame by preceding expansion rack device, and before the position is higher than shifting board and with the line of centers be axis of symmetry be symmetrically distributed two before expand framves, be installed on the front frame and the engine installation that cooperates with preceding expansion frame, be installed on the front frame and with preceding expansion frame bonded assembly guide piece, and be installed on the front frame and with preceding shifting board bonded assembly translation returning device; Back shaft platform comprises after poppet, the translation roller is installed on it and is the two back movable stands that axis of symmetry is symmetrically distributed with the line of centers, the translation roller rolls with after poppet and cooperates, be positioned on the movable stand of back and by turntable bearing and back movable stand bonded assembly two rotating disks, the a plurality of swing rollers that roll and cooperate with the back movable stand are installed on the rotating disk, with rotating disk and back movable stand bonded assembly swing returning device, expanding rack device by the back is connected on the after poppet and the position is higher than rotating disk and be that framves are expanded in two backs that axis of symmetry is symmetrically distributed with the line of centers, be installed on the after poppet and and expand the engine installation that frame cooperates with the back, be installed on the after poppet and expand frame bonded assembly guide piece with the back, be installed on the after poppet and with back movable stand bonded assembly translation returning device.Wherein, preceding expansion rack device is made up of with the front rod that the front rod seat is rotationally connected the front rod seat that is fixed on the front frame, and front rod is connected with preceding expansion frame; Rack device is expanded by the rear linking rod seat that is fixed on the after poppet in the back, the rear linking rod that is rotationally connected with the rear linking rod seat, and connect rear linking rod and back and expand the slip free bearing of frame and form.Engine installation is generally two covers, every cover engine installation is by cylinder block, the cylinder that is installed on the cylinder block is formed, its cylinder piston rod expands frame with preceding expansion frame or back respectively and is connected, piston rod movement, expand frame or back before promoting and expand frame and move, expand framves or two backs before linkage keeps two and expand framves parallel motion symmetrically synchronously.Before being exclusively used in, expands guide piece the guiding that frame is expanded in frame or back, making two preceding expansion framves or two back expansion framves be parallel to line of centers all the time moves, it is respectively by the guide holder that is fixed on front frame or the after poppet, be installed in the bearing set on the guide holder, and one end expand frame with preceding expansion frame or back respectively and be connected, the other end is formed with the pilot bar that the bearing set rolling cooperates, expand before general one and expand frame behind frame or one two guide piecees should be arranged, be installed in respectively and expand the frame two ends, guarantee to expand frame path of motion whenever and all be parallel to line of centers.The return of shifting board or back movable stand before the translation returning device is exclusively used in, be after each tested automobile sails out of, can both automatically reset, it is by the return seat that is installed in respectively on front frame or the after poppet, be rotatably connected on the return bar on the return seat, respectively with preceding shifting board or the back movable stand return plate of captiveing joint, be arranged on the return plate and the finger that cooperates with the return bar, and the one end is separately fixed on front frame or the after poppet, the pull back spring that the other end is fixed on the return bar is formed, before tested automobile leaves shifting board and after behind the movable stand, because spring force makes return bar return, during return bar return, stirs finger, make the return sheet reset, thereby shifting board resets with the back movable stand before making.The swing returning device by with back movable stand bonded assembly support, with rotating disk bonded assembly compression spring seat, and one end stretch in the compression spring seat, the other end and support bonded assembly swing pull back spring are formed, because the swing returning device is the both sides that symmetry is installed in back movable stand and rotating disk, when rotating disk is that axle center and the rolling by the swing roller produce when swing with the turntable bearing, promptly produce relative angular displacement with the back movable stand, at this moment, the compression spring of rolling to each side in the returning device just produces difference of pressure, after automobile sailed out of, rotating disk just can automatically reset.The slip free bearing is arranged in the free bearing body and with rear linking rod bonded assembly bearing and forms by expanding frame bonded assembly free bearing body with the back, and it can bear the pulling force and the thrust of rear linking rod.

The advantage of the utility model Automobile turntable be accurately to ajust left alone without help on detection line head lamp detect tested automobile before the left alone without help fare, make its longitudinal centerline and the utility model central lines, to satisfy the pacing factor that detects the car headlamp light-beam position, easy to use, be suitable for various types of vehicles and use.
