For a more clear explanation of the present application, the working principle and method of the present application will be further explained by taking the embodiments shown in fig. 2 to 4 as examples:
the automatic brake handle 10 of the brake controller is provided with a running position, an initial brake position, a full brake position, a suppression position, a reconnection position and an emergency brake position, and the single brake handle 11 is provided with a running position, a full brake position and a side buffer position.
Specifically, the first servo motor rotates to drive the first transmission mechanism 3 to rotate, the first transmission mechanism 3 is formed by meshing a large gear and a small gear, the large gear is connected with the first clamping mechanism 6, and the first clamping mechanism 6 is fixedly connected with the automatic braking handle 10 of the braking controller. Therefore, under the driving of the first servo motor, the first transmission mechanism 3 drives the first clamping mechanism 6 to synchronously rotate, and meanwhile, the first clamping mechanism 6 drives the automatic brake handle 10 of the brake controller to rotate back and forth, so that the gear conversion of the automatic brake handle 10 is realized.
More specifically, the first clamping member 61 drives the first connecting member 62 to rotate, the first connecting member 62 drives the three-dimensional load cell to rotate, and the three-dimensional load cell simultaneously drives the first clamp 63 to rotate, and the automatic brake handle 10 is driven to rotate under the action of the first clamp 63. Further, when the automatic brake handle 10 leaves a certain position, the force value required when leaving a certain position is relatively large because the automatic brake handle 10 has a positioning structure, when the automatic brake handle 10 enters another position, a sliding-in process can be generated because of the positioning structure, at this moment, the force value measured by the sensor can be rapidly reduced, meanwhile, when leaving the position, the measured force value can be rapidly increased, at this moment, a force can be formedThe value jitter peak. During the test of the automatic brake handle 10, 6 peak values are formed from the operation position to the emergency braking position, namely, one peak value corresponds to each gear position, each peak value of the test of the automatic brake handle 10 is the maximum pushing force of the automatic brake handle 10 moving away from the corresponding gear position, and the distance d between the first clamping piece 61 and the rotation center of the first clamping piece 611Is a fixed value, i.e. this distance d1Is the turning radius r of the automatic brake handle 101. The industrial personal computer 1 acquires the peak value transmitted back by the three-dimensional force transducer, namely the maximum force value F1According to the radius r of rotation of the automatic brake handle 101The industrial personal computer 1 adopts the maximum force value F of the automatic brake handle 10 leaving the corresponding gear1Radius r of rotation of brake handle 101Multiplying and calculating a damping (torque) value corresponding to the peak value, namely obtaining the handle damping of the automatic brake handle 10 leaving the corresponding position, so as to realize accurate testing of the damping of the automatic brake handle 10.
Similarly, when the individual brake handle 11 is shifted, two peak values are formed in the process, each peak value of the test of the individual brake handle 11 is the maximum pushing force of the individual brake handle 11 moving away from the corresponding shift position, and the distance d between the second clamping member 71 and the rotation center of the second clamping member 712Is a fixed value, i.e. this distance d2For braking the radius of rotation r of the handle 11 alone2. The industrial personal computer 1 acquires the peak value transmitted back by the three-dimensional force transducer, namely the maximum force value F2(ii) a According to the radius r of rotation of the individual brake levers 112The industrial personal computer 1 adopts the maximum force value F of the automatic brake handle 10 to leave the corresponding gear2Radius r of rotation of the independent brake handle 112Multiplying and calculating a damping (torque) value corresponding to the peak value, namely obtaining the handle damping of the independent brake handle 11 leaving the corresponding position, and realizing accurate testing of the damping of the independent brake handle 11.
At the same time, the rotation speed n of the first servo motor1Is constant in the test process according to the time t of each peak value acquired by the industrial personal computer 11The angle of the first servo motor rotating at two peak values can be calculated according to the transmission ratio i between the first clamping piece 61 and the first servo motor1Can beCalculates the angle a of the automatic brake handle 10 moving between the gears1. Similarly, the rotation speed n of the second servo motor2Is constant in the test process according to the time t of each peak value acquired by the industrial personal computer 12The angle of the second servo motor rotating at two peak values can be calculated according to the transmission ratio i between the second clamping piece 71 and the second servo motor2The angle a of the individual brake lever 11 moving between the gear positions can be calculated2。
Furthermore, a linear pull rod displacement sensor, a screw 81 and a third servo motor are arranged on the single brake handle 11. The industrial personal computer 1 can control a third servo motor, the third servo motor drives a lead screw 81 to rotate, the lead screw 81 drives a linear pull rod displacement sensor to move in the left and right directions, and meanwhile, the three-dimensional force measuring sensor, the second clamp 74 and the independent brake handle 11 are driven to move; when the side of the single brake handle 11 is slowed to the limit position, the three-dimensional force measuring sensor can instantly output a larger force value F3And apply the force value F3Transmit industrial computer 1, PLC control system in the industrial computer 1 receives this signal after, can control third servo motor stop motion, and linear pull rod displacement sensor can transmit the lateral displacement numerical value S who gathers to PLC control system this moment on, and industrial computer 1 calculates the angle that the side is slow according to this lateral displacement numerical value S and the length L of brake handle 11 alone.
In conclusion, by adopting the testing equipment and the testing method, the damping size of the handle can be automatically and accurately tested, and powerful test support is provided for damping adjustment; meanwhile, reliable test conditions are provided for whether the moving angle between the gears of each handle meets the requirements after the brake controller is assembled; and, still realize the measurement to the brake controller alone brake handle 11 side slow angle. In addition, when the test equipment is used for testing, the brake controller is also very convenient to install, a one-key operation test is realized, and the test efficiency is improved. The technical problem that in the prior art, the damping of the handle of the brake controller is tested in a manual push-pull mode, so that the damping of the handle cannot be accurately tested is solved. Meanwhile, the technical problems that the measurement of the moving angle of each gear of the brake controller in the prior art is only limited to the measurement on a control positioning part and the angle of each gear cannot be measured after the assembly is finished are solved; in addition, the technical problem that the side slow angle of the brake handle 11 alone of the brake controller in the prior art cannot be measured is solved.
