Along with the development of auto industry, the pendulum that the safety problem of tire also becomes increasingly conspicuous is in face of people.All can there is national compulsory safety verification project before general tire shipment, comprise tire intensity service check, tire bead unseating resistance service check, the inspection of tyres durable performance and the inspection of tire high speed performance.Wherein tire casting-off resistance experiment mainly carries out for car tubeless tyre, because in the process of running at high speed, it turns to centrifugal force very large to car, for there is the tire of mass defect likely because making tyre and rim throw off gas leakage thus cause serious security incident by the impact of steering force.
Regulation tire bead unseating test in " GB/T4502-2009 tyres for passenger cars performance Experimental Method in Laboratory ", casting-off pressing block is placed in tire sidewall surface, the crossbeam initial position level of fixing casting-off pressing block.But traditional tire bead unseating test machine regulates the cross beam water complex steps at ordinary times of fixing casting-off pressing block, main by testing crew visual observations casting-off pressing block and tire sidewall surface contact whether, observe crossbeam level and mainly lean on surveyor's staff; If casting-off pressing block squeezes too tight with tire sidewall surface or does not contact, or the out-of-level test findings that all can make of crossbeam produces difference, the impact of testing crew subjective factor is large, and thus make testing equipment precision low, test findings is difficult to have comparability and repeatability.The data of synthesise various, Current Domestic does not also effectively improve this problem, in the case, the utility model proposes a kind of automatic level adjusting device, can well address this problem.
Utility model content
Utility model object:
The utility model be solve the crossbeam Level tune fixing casting-off pressing block in tire bead unseating test loaded down with trivial details, there is the problems such as error by testing crew visual observations, to improve for the purpose of device operability, test efficiency and test reliability, utilitarian design is novel.
Technical scheme:
In order to solve the problem, take a kind of new design proposal, by the Level tune robotization of tire bead unseating test middle cross beam, utilize servo-drive system and force measuring system and laser distance measuring system, the level of automatic adjustment crossbeam, makes casting-off pressing block and tire sidewall surface contact but does not produce large extruding force, all can automatically return to original horizontal position after every bit off-test, each on-test and at the end of all keep the horizontal level of crossbeam, thus make test findings objective, true.
The crossbeam level(l)ing device for tire bead unseating test machine of the utility model design, is made up of drive motor, lead screw guide rails transmission component, bracket assembly, force snesor and displacement sensor component.
Drive motor, lead screw guide rails transmission component are made up of two AC servo motor, motor cabinet, shaft coupling, screw-nut, line slideway auxiliary and limit bases, be installed on the screw-nut on motor cabinet and limit base, line slideway auxiliary forms kinematic pair, convert rotational motion is the rectilinear motion of screw by driven by motor leading screw.
Bracket assembly is made up of crossbeam and support, and crossbeam is connected by axle with support, and support can rotate centered by axle.
Force snesor and displacement sensor component are made up of pull pressure sensor and laser displacement sensor, force snesor upper end is connected with mair motor leading screw by bearing pin, lower end is connected with crossbeam by screw, laser displacement sensor is fixed on support, can measure the distance between crossbeam and support by the reflected signal of crossbeam.
Mair motor is utilized to control the upper-lower position of crossbeam near casting-off pressing block one end, utilize from the upper-lower position of Electric Machine Control crossbeam near support shaft one end, utilize the distance between laser displacement sensor control crossbeam movable end and support, utilize force snesor to control casting-off pressing block and tire sidewall surface contact.It is simple that the utility model has structure, compact, and good reliability is easy to operate, practical, the advantage that accuracy is high.
Beneficial effect:
The utility model has following beneficial effect:
(1) adjustment casting-off pressing block and tire sidewall surface contact are that system judges automatically before the test, avoid the error of testing crew range estimation subjective determination, guarantee that test error is all in testing standard claimed range each time.
(2) each testing site is terminated crossbeam and is returned Shi Douhui and get back to original horizontal position, manually adjusts the level of crossbeam, reduces the labour intensity of testing crew, add the accuracy of test findings, reach the effect of anticipation without testing crew.
(3) in result of use, the utility model is simple for structure, and operability is good, adjusts easy for installation, saves function admirable from damage.

Embodiment
Embodiment: in the accompanying drawings, the utility model is used for the crossbeam level(l)ing device of tire bead unseating test machine, by axle (1), support (2), mair motor leading screw (3), mair motor (4), guide rail (5), from motor (6), shaft coupling (7), bearing pin (8), screw (9), force snesor (10), laser displacement sensor (11), crossbeam (12), forms from motor leading screw (13), casting-off pressing block (14) and each several part assembly holding screw.
Support (2) is fixed on apparatus body by guide rail, and one end is fixed with from the screw (9) motor leading screw (13), and the other end is connected with crossbeam (12) by axle (1).By controlling can control support (2) upper-lower position from motor (6), and then control the position that crossbeam (12) is attached thereto one end.
Crossbeam (12) in addition one end is connected with mair motor leading screw (3) by force snesor (10), can control the position of crossbeam (12) relative to support (2) by controlling mair motor (4).
Laser displacement sensor (11) is fixedly installed on support (2), can determine crossbeam (12) distance between movable end and support by the reflected signal of crossbeam (12).After initial positions is given, any point off-test, crossbeam (12) and initial horizontal level can be back to.
Casting-off pressing block (14) and tire sidewall surface contact before on-test but do not produce extruding, adjust by force snesor (10).After installing test tire, control mair motor (4) with certain speed ratio, run from motor (6), support (2), axle (1), crossbeam (12) entirety is made to shift near tire downwards, when having feedback signal to force snesor (10), mair motor (4), out of service from motor (6).Judge that this signal is no more than test error and judges that casting-off pressing block (14) and tire sidewall surface contact meet the requirements; If exceed test error requirement, then system automatic reverse runs, till making the signal of force snesor (10) reach requirement.
The automatic adjustment of this process implementation to tire bead unseating test middle cross beam level, thus make test findings just accurate, decrease the labour intensity of personal error and testing crew.No matter from operability, or experiment automatized level, all there is larger lifting.
