Detailed Description
The utility model is further described below with reference to the drawings and specific examples.
As shown in fig. 1-3, the tail reducer dragging and starting moment detection device in the helicopter according to the embodiment of the utility model comprises a bottom plate 1, a slide box 2, a torque test assembly 3 and a distance detection assembly 4 (such as a laser sensor); the bottom plate 1 is installed on an integral bracket through up-down lifting of an up-down telescopic piece, two parallel horizontal guide rails 101 are arranged on the bottom plate 1, a plurality of sliding blocks 102 are arranged on the back surface of the sliding box 2, sliding grooves are formed in the sliding blocks 102, and the corresponding horizontal guide rails 101 are positioned in the sliding grooves of the sliding blocks 102, so that horizontal sliding of the sliding blocks 102 on the horizontal guide rails 101 is realized; the torque testing component 3 is arranged on the front surface of the sliding box 2; the torque testing assembly 3 includes a servo motor 301, a torque limiter 302 (e.g., a torque limiter), a torque detector 303 (e.g., a torque sensor), and a docking member 304 (e.g., a sleeve); the servo motor 301, the torque limiter, the torque sensor and the sleeve are sequentially in butt joint; the torque sensor is electrically connected with the servo motor 301; a floating joint 305 is arranged between the sleeve and the torque sensor; a guide rod thin cylinder 306 is arranged between the torque limiting piece 302 and the floating joint 305; the distance detection assembly 4 is located on one side of the docking piece 304.
Specifically, the torque limiter is a component for protecting the torque sensor, so that a larger clamping stagnation phenomenon is prevented when a workpiece rotates, and the torque limiter is additionally arranged after exceeding the measuring range of the torque sensor and being used in an overscan manner, so that the torque sensor is damaged. When the set torque of the torque limiter is smaller than the maximum measurement range of the torque sensor, if the rotation torque of the workpiece is larger than the set range of the torque limiter, the torque limiter automatically disconnects the rotating shaft system and alarms, and the servo motor 301 stops rotating.
Because the cylinder force driving the bottom plate 1 to move downwards is larger, the shaft of the torque detection member 303 is thinner, the detection torque is smaller (less than or equal to 1 Nm), and if the bottom plate 1 directly drives the floating joint 305 to contact the product, the torque detection member 303 is easy to damage. Therefore, the guide rod thin air cylinder 306 is adopted to drive the floating joint 305 to be finally in butt joint with the product. The guide rod thin cylinder 306 has a small force value, and can fully protect the torque detection member 303 from impact damage. The floating joint 305 can be relatively moved by providing a certain elasticity between the sleeve and the torque detecting member 303, and the influence of the force during the torque measurement on the measurement accuracy can be avoided. The floating connector 305 may be a conventional fixed floating connector or a floating connector, which will not be described herein.
When the dragging or starting moment is measured, the flange tool driving plate is firstly manually placed on the flange plate, after the bottom plate 1 and the slide box 2 move to the set positions, the guide rod thin cylinder 306 is released, the butt joint piece 304 is in butt joint with the flange tool driving plate, and whether the butt joint piece 304 is attached to the flange tool driving plate is measured through the distance detection assembly 4. If the abutting piece 304 is attached to the flange tool driving plate, a torque detection program is started. If the butt joint part 304 is not attached to the flange tool driving plate, the guide rod thin air cylinder 306 is retracted to lift the floating joint 305, the servo motor 301 drives the floating joint 305 to rotate by a certain angle according to a system setting program, the guide rod thin air cylinder 306 is released again, so that the cylindrical pin on the butt joint part 304 is clamped into the annular hole of the flange tool driving plate in a floating mode, attachment is completed, and therefore a torque detection program is started.
According to the dragging and starting moment detection device for the tail speed reducer in the helicopter, a servo driving rotation technology is adopted, when dragging and starting moment is measured, the input shaft is driven to rotate by the servo motor 301, and the problems of uneven rotating speed and non-horizontal rotating speed during manual rotation are solved; the torque sensor is adopted to measure the rotation moment of the input shaft, the torque value is read in real time, the maximum, minimum, running and other torques are automatically recorded, and whether the measurement result is qualified or not is automatically judged through a torque real-time curve; the torque sensor is protected by the torque limiter, meanwhile, the measurement reliability is improved by additionally arranging the floating joint 305, and the torque detection piece 303 is protected from damage caused by impact during butt joint by additionally arranging the guide rod thin cylinder 306 with a small force value.
In addition, the detection device is integrally arranged on the equipment substrate of the detection system, and the detection system further comprises a speed reducer automatic positioning and clamping device (a conventional cylinder clamping mechanism), an electric control system, a data processing system and the like. Wherein the equipment matrix is the basis of the whole equipment, other devices and mechanisms are fixed on the matrix, and the equipment matrix is formed by welding high-rigidity and high-strength steel plates; the automatic positioning and clamping device of the speed reducer is responsible for positioning and clamping the middle-tail speed reducer on the equipment, and is convenient for automatic butt joint measurement of each detection device and the speed reducer. The electric control system mainly comprises a PLC (programmable logic controller), an HMI (human machine interface), a low-voltage electric system, a safety light curtain and other control systems and a safety system and is responsible for motion control, logic action and the like of the whole equipment. The data processing system consists of an industrial personal computer, an acquisition plate, data processing software and the like and is responsible for acquisition, analysis, judgment, data storage, uploading and downloading, summarization, report production and the like of the data of each sensor of the whole equipment.
