The third embodiment is different from the first embodiment or the second embodiment in that the rest of the structures of the present embodiment are as follows:
As shown in fig. 1, the booster test apparatus further includes a translation error prevention mechanism 9. The translation error prevention mechanism comprises a vertical limit sleeve 9.1 arranged on the frame, a vertical limit rod 9.2 arranged in the vertical limit sleeve in a sliding manner, a lower annular stop block 9.3 and an upper annular stop block 9.4 arranged on the vertical limit rod, a limit piece 9.6 arranged on the sliding support, a vertical limit hole 9.7 arranged on the limit piece, a floating flat plate 9.5 positioned between the lower annular stop block and the upper annular stop block and a connecting piece 9.8 for connecting the lifting flat plate and the floating flat plate. The lower annular stop block is propped against the upper end of the vertical limiting sleeve. The floating flat plate is a long slat. The length direction of the floating flat plate is parallel to the first horizontal guide rail.
When the sliding support abuts against the inner limiting block, the vertical limiting hole is located right above the vertical limiting rod.
After the sliding support is abutted against the inner limiting block, in the process that the jacking mechanism drives the lifting flat plate to ascend, the floating flat plate is abutted against the upper annular stop block and drives the vertical limiting rod to move upwards, so that the vertical limiting rod extends into the vertical limiting hole; specifically, after the sliding support is abutted against the inner limiting block, the lifting mechanism drives the lifting flat plate to ascend, and before the motor driving part of the booster on the lifting flat plate is contacted with the test needle bed, the vertical limiting rod extends into the vertical limiting hole.
After the motor driving part of the booster is tested, the lifting mechanism is controlled to drive the lifting flat plate and the booster to descend and reset; then, the translation actuating mechanism can be controlled to drive the sliding support, the lifting flat plate and the booster to move; however, in the actual working process, an operator is unfamiliar or careless, an operation error occurs, before the lifting mechanism drives the motor driving part of the lifting flat plate and the booster to descend, and before the motor driving part is separated from the test needle bed, the translation actuating mechanism is controlled to drive the sliding bracket, the lifting flat plate and the booster to move, so that the motor driving part bends the test probe of the test needle bed and cannot be used, in order to solve the problem, the inventor tries to control the actions of the translation actuating mechanism and the lifting mechanism through automatic control, so that although the problem can be solved in most cases, manual control is needed in many cases, for example, when the automatic control is in fault, the maintenance is needed, the exercise operation is needed, and the like, so that the problem still exists, in order to thoroughly solve the problem, the inventor designs the translation error preventing mechanism,
After the motor driving part of the booster is tested, the lifting flat plate is driven by the jacking mechanism to descend and the motor driving part of the booster is driven by the jacking mechanism to descend, so that before the motor driving part is separated from the test needle bed, the vertical limiting rod is inserted into the vertical limiting hole, and the sliding support can be limited to translate through the cooperation of the vertical limiting rod and the vertical limiting hole;
And after the jacking mechanism drives the motor driving part of the lifting flat plate and the booster to descend and reset, the vertical limiting rod moves downwards and is separated from the vertical limiting hole, and at the moment, the translation actuating mechanism can smoothly drive the sliding support, the lifting flat plate and the booster to move, so that normal work is not influenced.
The foregoing description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any simple modification, variation and equivalent transformation of the above embodiment according to the technical substance of the present invention still fall within the scope of the technical solution of the present invention.
