[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Reference Figure 1The utility model provides an embodiment: a generator EP meter test device, including a workbench 1, a detection component is arranged on the surface of the workbench 1, and the detection component includes a limit groove 11, a hydraulic cylinder 12, a test plate 13, a probe 14, and a mounting block 15. The workbench 1 is provided with limit components on both sides of the detection component, the detection component is used to detect the generator EP meter, and the limit components are used to position the two sides of the generator EP meter.
[0029] Reference Figure 1 - Figure 2 The surface of the workbench 1 is fixedly connected with a mounting frame 2, and the side wall of the mounting frame 2 is provided with a plurality of array-distributed slide grooves 3, and the inside of the slide groove 3 is slidably connected with a moving seat 4, and the slide groove 3 is used to provide a track for the moving seat 4 to move up and down, and to guide it, and the surface of the mounting frame 2 is fixedly connected with a driving motor 31, and the output shaft of the driving motor 31 penetrates and is rotatably connected to the inner wall of the slide groove 3, and the end of the output shaft of the driving motor 31 is fixedly connected with a screw rod 32, and the bottom end of the screw rod 32 is rotatably connected to the inner wall of the slide groove 3, and the screw rod 32 penetrates and is threadedly connected to the bottom surface of the moving seat 4. The driving motor 31 is used to drive the screw rod 32 to rotate, so that the position of the moving seat 4 moves downward, and the end of the moving seat 4 is fixedly connected with a cross plate 41, and the side wall of the cross plate 41 is fixedly connected with a support plate 42, and a reinforcement component 5 is arranged on the surface of the support plate 42, and the cross plate 41 fixes the support plate 42 and the moving seat 4 together, so that the support plate 42 moves synchronously, so that the reinforcement component 5 reinforces the generator EP meter.
[0030] Reference Figure 3 The reinforcement assembly 5 includes a threaded rod 51, which penetrates and is threadedly connected to the surface of the support plate 42. A brake wheel 52 is fixedly connected to the top of the threaded rod 51, and a turntable 53 is rotatably connected to the bottom of the threaded rod 51. The brake wheel 52 is used to facilitate the rotation of the threaded rod 51. The height of the turntable 53 can be adjusted by rotating the threaded rod 51. Grooves 54 are provided on both sides of the turntable 53. A hinge rod 55 is hinged inside the groove 54. A slider 56 is hinged at the bottom of the hinge rod 55. A through hole is provided on the side wall of the slider 56, and a cross bar 57 is slidably connected in the through hole. A fixing seat 58 is fixedly connected to both sides of the cross bar 57. A pressing plate 59 is fixedly connected to the bottom of the fixing seat 58. A rubber plate 510 is provided on the bottom of the pressing plate 59. When the reinforcement assembly 5 moves downward, the pressure plate 59 contacts the surface of the EP meter. Due to the different heights of the EP meter, the pressure plate 59 moves upward to different degrees, causing the inclination angle of the hinge rod 55 to change, making the distance between the pressure plate 59 and the turntable 53 smaller, thereby avoiding damaging the EP meter during the fixing process.
[0031] Two sets of symmetrically arranged guide rods 511 are fixedly connected to the surface of the pressing plate 59. The guide rods 511 penetrate and are slidably connected to the surface of the support plate 42. The guide rods 511 are used to guide the pressing plate 59, and will not rotate when the threaded rod 51 drives the turntable 53 to move downward. The pressing plate 59 is elastically connected to the support plate 42 via a return spring 512. The return spring 512 is used to provide elastic support to ensure the stability and appropriate rebound force of the pressing plate 59, so that a certain pressure is provided when the pressing plate 59 contacts the surface of the EP meter.
[0032] Working principle: When using the generator EP meter testing device, first, place the generator EP meter to be tested on the detection component of the workbench 1, and ensure that both sides of the EP meter are accurately positioned by the limit components. Then, start the drive motor 31, the output shaft of the drive motor 31 drives the screw rod 32 to rotate, and the rotation of the screw rod 32 drives the moving seat 4 to move downward along the track of the slide slot 3.
[0033] As the moving seat 4 moves downward, the horizontal plate 41 and the supporting plate 42 also descend synchronously, so that the reinforcement assembly 5 gradually approaches the surface of the generator EP meter. Since the height of the generator EP meter may vary, the pressure plate 59 will move upward to varying degrees due to the height difference when it contacts the EP meter. This movement will further adjust the inclination angle of the hinge rod 55, while avoiding damage to the EP meter due to excessive pressure. The operator can rotate the threaded rod 51 by rotating the brake wheel 52, and the rotation of the threaded rod 51 will drive the turntable 53 to move downward to accurately position the generator EP meter.
[0034] During the process of the pressure plate 59 contacting the EP meter and applying pressure, the return spring 512 provides appropriate elastic support to ensure the stability and appropriate rebound force of the pressure plate 59, so that the pressure plate 59 can provide a certain pressure when contacting the surface of the EP meter, but at the same time will not damage the EP meter due to excessive pressure.
[0035] After the reinforcement component 5 stably fixes the generator EP meter in the test position, the detection component starts to work. The limit groove 11, hydraulic cylinder 12, test plate 13 and probe 14 and other components work together to test various indicators of the generator EP meter. During the entire test process, the reinforcement component 5 always maintains stable reinforcement of the EP meter to ensure the accuracy and reliability of the test results.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
