Description

Technical Field

[0001] The present invention belongs to the technical field of instrument transformer testing equipment and relates to an instrument transformer testing robot for laboratory use. Background Art

[0002] An instrument transformer testing robot is an intelligent device used for automatically detecting, calibrating, and diagnosing the performance of instrument transformers (such as current transformers and voltage transformers). It combines mechanical automation, sensor technology, data analysis, and artificial intelligence, aiming to improve testing efficiency, reduce manual operation errors, and meet the testing requirements of instrument transformers in complex environments.

[0003] In a laboratory environment, in order to improve the batch calibration efficiency, an instrument transformer testing robot is used to replace the traditional manual test bench. Therefore, the instrument transformer testing robot needs to have characteristics such as high precision, automation, and flexible adaptability. During testing, the instrument transformer is usually clamped on the end effector of the robot manipulator. The end effector is the direct contact part between the manipulator and the instrument transformer to be tested and is responsible for operations such as grasping, positioning, and fixing. Traditional fixtures are all replaceable and installed on the end effector of the manipulator. For bushing-type instrument transformers, a ring-shaped jaw is used to wrap the outer wall of the porcelain bushing of the instrument transformer. For post-type instrument transformers, clamping plates are used for clamping and fixing. Using the traditional method of replacing fixtures is not only very troublesome to operate, has poor flexibility, resulting in low testing efficiency, but also is prone to damage of the fixtures due to frequent replacement. Therefore, we propose an instrument transformer testing robot for laboratory use to solve the above-mentioned problems. Summary of the Invention

Detailed implementation manners

[0038] The following specific examples illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] Embodiment 1: As Figures 1-4 shown, a transformer testing robot for laboratory use includes a robot end effector arm 1 provided on a robot body, and a connecting plate 2 is connected to the end effector arm 1. By controlling the robot end effector arm 1 through a control system, the movement and horizontal rotation adjustment of the connecting plate 2 can be realized, so as to accurately position the transformer. At the bottom of the connecting plate 2, a clamping seat 6 is fixedly suspended by two symmetrically arranged connecting columns 3. An arc-shaped notch 62 is formed on one side of the clamping seat 6 for the docking and accommodation of the transformer. An arc-shaped rubber pad 9 is fixedly connected to the inner side wall of the arc-shaped notch 62 to increase the clamping stability and prevent the transformer from falling during movement.

[0040] The interior of the clamping seat 6 is provided with a clamping rod mechanism for positioning and clamping bushing current transformers of different specifications. Specifically, the clamping rod mechanism includes a bottom groove 61 opened at the bottom of the clamping seat 6, and a sliding strip plate 13 is slidably connected to the top inner wall of the bottom groove 61. On one side of the sliding strip plate 13, two connecting strip plates 15 are symmetrically and fixedly connected, and these two connecting strip plates 15 are respectively slidably connected to the two inner side walls of the bottom groove 61. On the side where the two connecting strip plates 15 are close to each other, racks 16 are fixedly connected, and an electric push rod 14 is also fixedly connected to the top inner wall of the bottom groove 61, and its output shaft is fixedly connected to one side of the sliding strip plate 13.

[0041] In addition, the clamping rod mechanism further includes two rotating shafts 17 symmetrically and rotatably connected to the top inner wall of the bottom groove 61. Fixed sleeves are sleeved on the outer walls of the two rotating shafts 17, and gears 18 meshing with the corresponding racks 16 are provided. Fixed sleeves are also sleeved on the outer walls of the two rotating shafts 17, and positioning clamping rods 10 extending into the arc-shaped notch 62 are provided. Two through holes 63 communicating with the bottom groove 61 are symmetrically opened on the inner wall of the arc-shaped notch 62, and one side of each of the two positioning clamping rods 10 passes through the corresponding through hole 63.

[0042] When it is necessary to test the bushing current transformer, first, the control system is used to control the end effector 1 of the robot to drive the connecting plate 2 to move, so that the bushing current transformer corresponds to the arc-shaped notch 62. Then, the electric push rod 14 is started to drive the sliding strip plate 13 to move, and then the two racks 16 are driven to move simultaneously through the two connecting strip plates 15. The meshing movement of the racks 16 and the gears 18 drives the two rotating shafts 17 to rotate, so as to drive the two positioning clamping rods 10 to move closer to each other in the corresponding through holes 63 at the same time, and clamp and fix the bushing current transformer at the middle position of the arc-shaped notch 62.

[0043] The present invention can be used in the field of transformer testing robots for laboratories, and can also be applicable to other fields of the present invention.

[0044] Embodiment 2: As a further improvement of the previous embodiment, as Figures 1-8 shown, the testing robot further includes a mounting plate 5 provided above the top of the clamping seat 6, and a driving mechanism for driving the mounting plate 5 to move and adjust is provided on the top of the clamping seat 6. The driving mechanism includes a lead screw motor 11 fixedly connected to the top of the clamping seat 6, a first fixing block 7 is fixedly connected to one side edge of the top of the clamping seat 6, a lead screw 19 is rotatably connected to one side of the first fixing block 7, and the end of the lead screw 19 away from the first fixing block 7 is fixedly connected to the output shaft of the lead screw motor 11. A first nut block 8 slidably connected to the top of the clamping seat 6 is fixedly connected to one side edge of the bottom of the mounting plate 5, and the first nut block 8 is threadedly sleeved on the lead screw 19. Starting the lead screw motor 11 to drive the lead screw 19 to rotate can drive the first nut block 8 to move back and forth on the top of the clamping seat 6, and further drive the mounting plate 5 to move back and forth for adjustment.

[0045] In addition, a vertical plate 12 is fixedly connected to the top of the mounting plate 5. Two guide rods 4 are symmetrically penetrated through the inside of the vertical plate 12, and one ends of the two guide rods 4 are fixedly connected to one side of the connecting plate 2. By guiding and moving the vertical plate 12 on the guide rods 4, the stability of the movement of the entire mounting plate 5 can be further improved, and at the same time, the stability of clamping the current transformer can also be improved.

[0046] A clamping plate mechanism is provided on one side of the bottom of the mounting plate 5 for correcting the deviation of the bushing type current transformer and clamping and fixing current transformers of different specifications of post type at the same time. The clamping plate mechanism includes two connecting blocks 20 symmetrically and fixedly connected to one side of the bottom of the mounting plate 5. Two sliding rods 22 are symmetrically and fixedly connected to the mutually remote sides of the two connecting blocks 20. The same slider 23 is slidably sleeved on the two sliding rods 22 on the same side. The bottoms of the two sliders 23 are fixedly connected with positioning clamping plates 24 located above the positioning clamping rods 10. Anti-slip lines are provided on the mutually approaching sides of the two positioning clamping plates 24 to increase the clamping stability.

[0047] In order to realize the movement control of the positioning clamping plate 24, an arc-shaped plate 25 is fixedly connected to the bottom of the mounting plate 5. Two arc-shaped sliders 26 are symmetrically and slidably connected to the outer side wall of the arc-shaped plate 25. Lower support blocks 27 and upper support blocks 29 are fixedly connected to the outer side walls of the two arc-shaped sliders 26. The tops of the two lower support blocks 27 are rotatably connected with connecting rods 28, and the other ends of the two connecting rods 28 are respectively rotatably connected to the tops of the corresponding sliders 23. Vertical rods 30 are fixedly connected to the tops of the two upper support blocks 29. The tops of the vertical rods 30 penetrate through the top of the mounting plate 5 and extend upward. Two arc-shaped strip holes 52 are symmetrically formed in the top of the mounting plate 5 and are in through-fit with the corresponding vertical rods 30.

[0048] Furthermore, two second fixing blocks 32 are symmetrically and fixedly connected to one side of the top of the mounting plate 5, and the same bidirectional screw 33 is rotatably connected between the two second fixing blocks 32. One side of the mounting plate 5 is fixedly connected to a support plate 21, and the top of the support plate 21 is fixedly connected to a servo motor 31. The output shaft of the servo motor 31 rotatably penetrates through one of the second fixing blocks 32 and is fixedly connected to one end of the bidirectional screw 33. Second nut blocks 35 are threadedly sleeved on both the positive and negative threaded sections of the bidirectional screw 33, and the bottoms of the two second nut blocks 35 are fixedly connected to moving blocks 34 that fit and slide on the top of the mounting plate 5. Strip-shaped holes 341 through which the top ends of the corresponding vertical rods 30 penetrate are formed in the tops of the two moving blocks 34. Starting the servo motor 31 to drive the bidirectional screw 33 to rotate can drive the two second nut blocks 35 to move relatively, and at the same time drive the two moving blocks 34 to move relatively. Furthermore, the two vertical rods 30 can be driven to move relatively in the corresponding arc-shaped strip holes 52 respectively. Through the arc-shaped movement of the arc-shaped slider 26 on the arc-shaped plate 25 and the cooperation of the connecting rod 28, the relative movement of the two positioning clamping plates 24 is realized, and the effect of correcting or clamping and fixing the current transformer is completed.

[0049] Embodiment 3: As a further improvement of the previous embodiment, as Figures 1-7 shown, a wire passing hole 51 is also formed in the top of the mounting plate 5, which is convenient for the wire to pass downward through the wire passing hole 51 during testing and then pass through the primary bushing hole in the bushing type current transformer. The wire passing hole 51 is designed in an elliptical shape, which can thread the wire at different positions and for different specifications of bushing type current transformers, making it more convenient to use.

[0050] Embodiment 4: As a further improvement of the previous embodiment, as Figure 1 、 Figure 9 shown, a plurality of sleeves 36 are fixedly connected to the inner wall of the arc-shaped notch 62 in an arc-shaped and equidistant manner, and one ends of the plurality of sleeves 36 all extend into the bottom groove 61. Inner rods 37 slidably penetrate through one ends of the plurality of sleeves 36 close to the arc-shaped rubber pad 9. The same return spring 38 is fixedly connected between one end of the inner rod 37 and the inner wall of one end of the sleeve 36, and the other end of the inner rod 37 is inserted into the arc-shaped rubber pad 9. When one side of the bushing type current transformer is squeezed and abutted against the arc-shaped rubber pad 9, the inner rod 37 can be pushed to extend into the sleeve 36 and the return spring 38 is squeezed. Through the abutment with the inner rod 37 and the elastic force of the return spring 38, the clamping and fixing effect on the bushing type current transformer can be further increased. When the fixation is released, the bushing type current transformer can be slowly rotated along with the positioning clamping rod 10, avoiding the situation that the bushing type current transformer falls off after the positioning clamping rod 10 rotates a little.

[0051] However, as is well-known to those skilled in the art, the working principles and wiring methods of the lead screw motor 11, the electric push rod 14, and the servo motor 31 are common knowledge, and they all belong to conventional means or well-known common sense. Therefore, they will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
