Description
Technical field
The utility model relates to a kind of detection platform, especially a kind of engine timing system phaser lock pin clearance detection platform.
Background technology
In the prior art, known technology is: VVT is wide model application on the new automobile engine, and it can promote engine capacity, moment of torsion, reduces oil consumption and exhaust emissions, the whole engine performance that improves.Continuous variable cam phaser system acts on blade by internal oil pressure and makes its deflection, has realized the step-less adjustment at phasing degree.When phaser is not worked, phaser is in lockup state, and phaser now is equivalent to a gear.When phaser is started working by the internal oil pressure effect, the system liquid force feed is pushed the rotor lock pin open, spinner blade deflection under the hydraulic oil effect, and phaser is started working.When phaser work is complete while getting back to initial position, lock pin is dropped into the locking pin seat hole.For ease of phaser lock pin energy smooth opening when initial position leads to oil, need to leave certain gap between lock pin and locking pin seat hole.Freely even rotor is not stuck likely to cause the phaser release when this gap is too small, if excesssive gap, engine is starting and the slow-speed of revolution is possible cause sound excessive, so must be controlled and detect in the lock pin gap when the initial position the phaser blade.
Traditional phaser lock pin gap detection adopts screw thread to drive fixedly time gear of profiling jaw, then rotor is connected with the rotation mandrel with screw, realizes the detection in phaser lock pin gap by rotation mandrel.In this pick-up unit, the installation of phaser is very loaded down with trivial details, and detection efficiency is not high, and it is poor to detect Data duplication, and this is the existing weak point of prior art.
The utility model content
The purpose of this utility model, be exactly for the existing deficiency of prior art, and a kind of technical scheme of engine timing system phaser lock pin clearance detection platform is provided, and this scheme is simple in structure, and testing process is simple and convenient, detects data more accurately and reliably.
This programme is achieved by the following technical measures: a kind of engine timing system phaser lock pin clearance detection platform, include control system, and frame, servomotor, transmission shaft, gear positioning mechanism, detect axle, cylinder and angular transducer; Servomotor and propeller shaft couplings; Transmission shaft is arranged at the middle part of frame bottom; The bottom of frame is provided with gear positioning mechanism; Cylinder is arranged at the frame top; Detecting axle connects with cylinder; Angular transducer is arranged at and detects on axle; Control system is for the motion of controlling servomotor and cylinder the data of accepting angular transducer output.
As this programme preferably: be provided with data display equipment on control system.
As this programme preferably: detect the axle bottom and be provided with friction pad.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because control system in this scheme is controlled the sequence of movement of each mechanism, and the information management that rotary angle transmitter is detected, between the phaser lock pin interstitial area by input, whether automatic discrimination is qualified, for underproof workpiece alarm.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment.
In figure, 1 is control system, and 2 is frame, and 3 is servomotor, and 4 is transmission shaft, and 5 is phaser rotor, and 6 is time gear, and 7 is gear positioning mechanism, and 8 for detecting axle, and 9 is cylinder, and 10 is friction pad, and 11 is angular transducer, and 12 is data display equipment.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and, in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing, can find out, this programme includes control system, frame, and servomotor, transmission shaft, gear positioning mechanism, detect axle, cylinder and angular transducer; Servomotor and propeller shaft couplings; Transmission shaft is arranged at the middle part of frame bottom; The bottom of frame is provided with gear positioning mechanism; Cylinder is arranged at the frame top; Detecting axle connects with cylinder; Angular transducer is arranged at and detects on axle; Control system is for the motion of controlling servomotor and cylinder the data of accepting angular transducer output.Be provided with data display equipment on control system.Detect the axle bottom and be provided with friction pad.
The utility model is controlled the each several part action by control system.After phaser is placed on to the detection station, gear positioning mechanism is fixed the phaser time gear, cylinder drives the detection axle and comes downwards to friction pad contact phaser rotor end face and be adjacent to, servomotor is clockwise to dead-centre position by the transmission shaft rotor driven, this Time Controller is by the zero setting of angular transducer angle, then the servomotor rotor driven is rotated counterclockwise to the position, dead point, rotor drives and detects the axle rotation by friction pad, now angular transducer reaches control system by the rotational angle signal of the detection axle that collects, after control system is processed the signal of angular transducer input, by the rotational angle of rotor, be that export by data display equipment in the lock pin gap, and be analyzed with the ultimate value of workpiece, to defective workpiece alarm, the purpose that reaches detected phase device lock pin gap and automatically judge.
The utility model, by friction gearing detected phase device lock pin gap, reduces the transmission error of intermediate transmission mechanism, makes phaser lock pin gap detection data more accurately and reliably.Control by the sequentially-operating of control system simultaneously, make testing process simple and fast more.
