Description
Technical field
The present invention relates to testing equipment, specifically, is a kind of testing machine detected for tire dynamic and balance.
Background technology
Doughnut is due to the reason of the aspect such as material and manufacture, more or less can there is mass distribution inequality, the problem that mass centre does not overlap with tire geometric center, when tire exists mass eccentricity, the radial force of alternation can be produced when High Rotation Speed, cause Vehicular vibration, produce noise, affect smoothness, time serious, can traffic hazard be caused, before therefore using, transient equilibrium detection must be carried out to tire.
The transient equilibrium checkout equipment of current use, lubricating system mainly adopts mechanical arm to position tire, complex structure, and strength controls difficulty, difficulty is regulated in fixed, large with the contact of tire, easily make softer squeegee action, destroy the shape that tire originally has, lubricating structure is immersed in lubricating fluid, lubricating fluid consumption is large, the locking mode that upper apparatus for locking main shaft mainly adopts is that gas pawl drives three lock dogs to step up, bearing pin location structure brings because of bearing pin wearing and tearing, bending, have impact on the circularity of three lock dog clampings, cause stepping up bias, axle cannot be alignd, the locking mode that lower main axis locking device mainly adopts is the gentle pawl locking of ball lock, ball lock is connected with lower main axis by the steel ball of air push shrinking device, complex structure, because steel ball and lower main axis are point cantact, steel ball easily weares and teares, locking effect is deteriorated, the locking of gas pawl uses gas pawl to step up lower main axis, locking effect is better, but gas pawl fixed installation testing machine is inner, inconvenience is installed, regulate difficulty, a year mechanism for tire for test station is all stationary stage, in tire transportation and process of the test, the sidewall of tire all likely rubs with table top, test position is caused to offset, affect test findings, serious meeting makes tire wear and tear, and table top size is fixed, the size of the tire that can hold is limited, poor compatibility.
A kind of dynamic balance test machine tool is devised at first patent number " full-automatic heavy load tyre static and dynamic balance weighing apparatus/jumping degree tester " patent No. ZL200620026711.7, although the robotization that tire dynamic and balance tests each operation can be realized to be carried out, multiple functional, automaticity is high, but still have many defects, utilize cylinder to promote lock dog and carry out lower main axis locking, locking poor stability, the alignment of shafts easily offsets, make dynamic balance running result inaccurate, main shaft is by wedge V belt translation, wedge band easily loosens, main shaft is vulnerable to shearing force, and shearing force regulates difficulty, cannot eradicate, affect the rotary balance of main shaft, affect operating accuracy, carried out the transmission of tire by roller-way between each station, roller-way location is inaccurate, many groups arm is installed center, structure is too complicated, printing equipment is provided with rotating mechanism, complex structure, angular setting bothers.
