Detailed Description
The following describes in further detail embodiments of the present invention.
As shown in fig. 1 to 6, an automatic generator stator electrical performance detection apparatus according to the present invention includes a frame 10 and a protective cover (not shown) covering the entire frame 10, wherein the protective cover is provided with a workpiece inlet (not shown) for a worker (or by a conveyor belt) to put a stator to be detected on the protective cover or to take a qualified stator away after detection.
An index plate 14 is horizontally and rotatably arranged on the frame 10, four stations are respectively arranged on the index plate 14, and a workpiece table 16 for placing a generator stator 20 is rotatably arranged at each station. In the present embodiment, four symmetrical circular holes (not shown) are formed in the index plate 14, that is, a bearing (not shown) is disposed in the circular hole, a cylindrical workpiece table 16 is disposed in the bearing, and an annular groove (not shown) is disposed on the upper surface of the workpiece table 16 for placing the generator stator 20. Of course, many other similar configurations will occur to those of ordinary skill in the art in view of the functional requirements described above. They are not shown or limited in detail since they are not important innovations of the present invention.
The four stations are sequentially as follows:
a loading and unloading station 18: the device is used for placing the generator stator 20 to be detected and taking away the detected generator stator 20;
pin positioning station 22: the workpiece table 16 is rotated through the servo motor 40, the pin positions of the generator stator 20 are detected through the sensors, after all the pin positions are determined, the workpiece table 16 is continuously rotated until all the pins of the generator stator 20 placed on the workpiece table rotate to the set positions, the sensors and the servo motor 40 are connected with the control system, and the positions of all the pins 201 of the generator stator 20 are jointly calculated through the control system according to the time when the pins 201 of the generator stator 20 are detected through the sensors and the stroke of the servo motor 40;
electrical property detection station 24: the detection joints are arranged according to set positions, and when the indexing disc 14 rotates the generator stator 20 adjusted in place at the pin positioning station 22 to the electrical property detection station 24, the pins of the generator stator 20 are automatically connected, so that electrical property detection is carried out on the generator stator 20;
a blanking station 26: the generator stator 20 that is inspected and determined to be qualified or unqualified is removed.
Specifically, the pin positioning station 22 includes a vertically disposed upright column 28, a cantilever 30 is disposed on the upright column 28, a detection cylinder 32 is disposed vertically downward below the cantilever 30, 4 photoelectric sensors 34 are disposed on a cylinder arm of the detection cylinder 32, transmitters or receivers of the photoelectric sensors 34 are respectively disposed on a support 36, and the support 36 is connected to the cylinder arm of the detection cylinder 32. As the workpiece table 16 of the pin positioning station 22 rotates, the pins of the generator stator 20 pass in sequence between the bracket 36 and the cylinder arm of the cylinder so as to be detected by the photoelectric sensor 34. The four brackets 36 are symmetrically arranged with respect to the cylinder arm of the detection cylinder 32, and this structure makes the workpiece table 16 rotate 90 degrees, which ensures that each pin is detected by one of the photosensors 34. Upon detection, the control system marks the number of the photoelectric sensor 34 that found the pin and the length of time the servo motor 40 was rotated after the pin was found. This allows the position of the offset of that leg from the photosensor 34 to be determined after the servo motor 40 has stopped (the speed of the servo motor 40 can be set and thus the duration determined and the angle of rotation of the servo motor 40 uniquely determined).
In this embodiment, a jacking cylinder 38 is vertically arranged below the pin positioning station 22, the servo motor 40 is arranged on a cylinder arm of the jacking cylinder 38, an output shaft of the servo motor 40 is vertically arranged upwards, a cylindrical connecting column 401 is arranged on the output shaft, and an elongated groove 402 is arranged on the end surface of the connecting column 401. A connecting hole (not shown) for inserting the connecting rod 401 is formed below the workpiece table 16, and a protruding strip (not shown) matching with the groove 402 is formed in the connecting hole. This allows the output shaft of the servo motor 40 to be inserted into the coupling hole, and then the rib is engaged with the groove 402, thereby driving the workpiece table 16 to rotate together.
Each station is provided with a support 42, a screw 44 is horizontally threaded on the support 42, a tension wheel 46 is horizontally arranged on the screw 44, and a belt 48 is sleeved between the tension wheel 46 and the workpiece table 16. The tension pulley 46 and the workpiece table 16 are connected by a belt 48, and the belt 48 is tensioned by rotating the screw 44, so that a large friction force is generated, and spontaneous rotation of the workpiece table 16 due to a small friction force in the process of moving the index plate 14 is avoided.
A rotary table 50 is horizontally and rotatably arranged between the loading and unloading station 18 and the workpiece inlet, a longitudinal rotary arm 52 is fixedly arranged on the rotary table 50, and two clamping jaws 54 for clamping the generator stator 20 are respectively arranged at two ends of the rotary arm 52. The operator places the generator stator 20 at the workpiece entrance, presses the button to cause the clamping jaws 54 to grip the generator stator 20, rotates the turntable 50 by 180 degrees to rotate the generator stator 20 to the loading and unloading station 18, and releases the clamping jaws 54 to cause the generator stator 20 to fall onto the workpiece table 16. The other jaw 54 is then picked up from the workpiece table 16 and the qualified generator stator 20 is delivered to the workpiece entrance for removal by the operator. By the structure, an operator is far away from an electrified part during detection, so that the safety is greatly improved.
Further, a wiring cylinder 56 is vertically arranged at the electrical property detection station 24, a plurality of finger cylinders 58 are arranged on a cylinder arm of the wiring cylinder 56, and an electrical connector 60 is arranged on each finger of the finger cylinders 58.
