Abstract
The invention relates to an automatic leveling support for analyzing and measuring the three coordinates of a defective automobile off the production line of the vehicle general assembly in an automobile company. A coordinate system is established before the analysis and measurement of the defective automobile, and the establishment of the coordinate system needs to level the automobile body first, which means, an Z-direction automatic leveling function of the automobile body is completed by the device and method provided by the invention. The device comprises four tyre supports, four height gauges four lifting-up devices, two gap bridges, a control cabinet, a control computer and eight cables. The method comprises the steps: the automobile is put on the four tyre supports, Z-direction heights of the four corners on the automobile body are real-time measured through four height gauges and are fed back to the control cabinets, the control cabinets convert the height difference between the measured value and the target value into the pulse output to the tyre supports, so that the Z-direction height of the automobile body is adjusted. The adjusting process is a closed loop cyclic adjustment, and the final adjusting precision is plus or minus 0.05mm.
Description
Technical field
The present invention relates to and a kind ofly for car load factory, the automatic leveling brace before three-dimensional analysis to measure is carried out to the general assembly problem vehicle that rolls off the production line, can by vehicle Z-direction automatic leveling, simulation production line vehicle-state, then carries out three-dimensional analysis to measure, orientation problem basic reason.
Background technology
General assembly completes car and occurs size correlated quality problem, three coordinate measuring machine is used to carry out analysis to measure to the size of problem correlated parts with regard to needing, orient the basic reason of problem, thus Instructing manufacture carries out quality optimization, and general assembly completes the vehicle body state of car because add chassis, vehicle body state and production status inconsistent, suspension can cause deformation to a certain degree to vehicle body.Therefore three coordinate measuring machine is when measuring body dimensions, need first by vehicle body Z-direction lifting leveling, release suspension acting force, ensures that vehicle body state is as far as possible consistent with production status.The result measured like this has direct directive significance to production.
The leveling of vehicle body Z-direction is connected with vehicle body lower-edge beam by four jacking apparatus, carries out lifting to vehicle body, and it is that the deviation of size and digital-to-analogue theoretical position is in ± 0.05mm that lifting finally needs to ensure that vehicle body Z-direction is built.Traditional regulative mode is four operator's Non-follow control, four jacking apparatus, and observe deviate, manual adjustments is until result meets the requirements.Because vehicle body belongs to rigid body, the variation of jacking apparatus, other three places numerical value will change, so need chronic in manual adjustments to ± 0.05mm tolerance, test the good teamwork degree of four operators, efficiency is very low simultaneously.
Summary of the invention
In order to promote vehicle body Z-direction leveling efficiency, simultaneously in order to save human cost, the invention provides a kind of automatic leveling brace, regulating command is sent by switch board leveling button, four jacking apparatus can carry out closed loop adjustment automatically according to the height value of height gauge measurement, until result meets tolerance, regulate complete.This brace not only saves the human cost of 3 operators, regulates efficiency to be greatly improved simultaneously, saves 4 hours consuming time for traditional leveling to 0.5 hour.
The technical solution adopted for the present invention to solve the technical problems is: this automatic leveling brace comprises four Tire support devices altogether (for Tire support, be convenient for measuring arm to probe into vehicle bottom and measure), four jacking apparatus (for by the jacking of vehicle body Z-direction thus release suspension acting force), (capturing that vehicle body four Z-directions build in real time by adaptive structure is position height for four height gauges, and reading is fed back to control computer), a switch board (comprises the appliance such as multi-axis motion controller and servo driving.Control the difference of computer computed altitude chi measured value and theoretical position, be converted into umber of pulse, drive four AC servo motor to carry out lifting or descending motion by multi-axis motion controller simultaneously, circulate this process, completes vehicle body Z-direction and regulate) and control computer (for running leveling software).First vehicle is placed on Tire support; Open switch board, then click and control computer surrounding interlock raise button, lifting jack is risen to close to bodywork height; By connector, lifting machine is connected with vehicle body; Place four height gauges to measuring position, control the Z-direction numerical value that namely computer can read height gauge, regain height gauge, click coarse adjustment button, lifting machine carries out coarse adjustment automatically puts down; After coarse adjustment, discharge and adjust height gauge position, release lifting machine X and Y-direction acting force, the coupling bolt on fastening lifting machine and ground; Click accurate adjustment button, lifting machine carries out Z-direction leveling automatically, until height gauge measured deviation is within ± 0.05mm, leveling completes.
The invention has the beneficial effects as follows, by plant equipment and control system, achieve the automatic flat-adjustable function of vehicle body Z-direction height, save human cost, and leveling precision is high.
