Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Please refer to fig. 1. According to the utility model discloses a servo driver aging testing system, including ageing room 1, a plurality of ageing servo motor 2, a plurality of to dragging servo motor 3, many to dragging servo driver 4 and controller 5.
The aging room 1 is internally provided with an aging rack 11, and the aging rack 11 is used for placing a plurality of servo drivers 9 to be tested.
A plurality of servo motor 2 that age, a plurality of to dragging servo motor 3, many to dragging servo driver 4 and controller 5 all set up outside ageing room 1, and a plurality of servo motor 2 that age, a plurality of to dragging servo motor 3 and many to dragging servo driver 4's quantity all is the same with the quantity of the servo driver 9 that awaits measuring.
The aging servo motors 2 are used for being respectively connected with the servo drivers 9 to be tested in a one-to-one correspondence mode, the output shafts of the pair dragging servo motors 3 are respectively connected with the output shafts of the aging servo motors 2 through the couplers 6 in a one-to-one correspondence mode, and the pair dragging servo drivers 4 are respectively connected with the pair dragging servo motors 3 in a one-to-one correspondence mode. In the present embodiment, the coupling 6 is a diaphragm coupling.
The controller 5 communicates with a plurality of servo drivers 9 to be tested and a plurality of drag servo drivers 4 through buses, respectively. In this embodiment, the controller 5 is an industrial personal computer. The controller 5 communicates with a plurality of servo drivers to be tested 9 and a plurality of pair-drag servo drivers 4 through an EtherCat bus.
Further, as shown in fig. 3, the controller 5 and a plurality of servo drivers 9 to be tested form a ring redundancy network, wherein the controller 5 is connected to the network ports of the servo drivers 9 at the head and the tail of the queue simultaneously. When a communication fault occurs in a certain servo driver 9 in the middle of the queue, the controller 5 may send out a test instruction in reverse direction, and continue to test other servo drivers 9 behind the faulty servo driver 9 in a reverse order manner without moving away the servo driver with the communication fault, thereby reducing the workload of the worker and improving the test efficiency.
Before the aging test system for the servo driver in this embodiment performs the aging test on the servo driver 9, the internal contracting brake of the counter-dragging servo motor 3 is opened. Then, the controller 5 controls the servo driver 9 to work in a rotating speed mode, so as to drive the aging servo motor 2 to rotate, and the aging servo motor 2 can drive the rotor of the twin-drag servo motor 3 to rotate together (at this time, the twin-drag servo motor 3 is not electrified). The controller 5 can know whether the aging servo motor 2 reaches the set rotation speed or not based on the feedback of the encoder of the aging servo motor 2. When the aging servo motor 2 reaches the set rotating speed, the controller 5 controls the drag servo driver 4 to start, and enables the drag servo driver 4 to work in a torque mode. The torque set for the counter-dragging servo driver 4 corresponds to the load driven by the aging servo motor 2, so that when the load of the aging servo motor 2 needs to be changed, only the torque set value of the counter-dragging servo driver 4 needs to be changed through the controller 5, and an inertia disc connected with the aging servo motor 2 does not need to be manually replaced like the prior art, so that the test efficiency is greatly improved.

The number of the vibration tables 71 is two, and the two vibration tables 71 are respectively placed on the two-layer shelf 111. The vibration table 71 has three vibration modes, i.e., low frequency, high frequency and synchronous impact, so that different vibration levels can be selected according to different application scenarios of customers.
