Description

Technical Field

[0001] This utility model belongs to the technical field of adjustable bridge rectifier test bases, specifically an adjustable bridge rectifier test base. Background Technology

[0002] A bridge rectifier test fixture is a specialized electronic device used for testing and securing bridge rectifiers. Its main function is to provide an interface for connecting and testing bridge rectifiers, ensuring their performance and reliability during operation. Components such as rubber pads also prevent damage from compression, providing protection. The test fixture is electrically connected to the bridge rectifier pins via a fixing block or metal plate, and these connection points are then connected to testing equipment via wires or probes, thus enabling the testing of the bridge rectifier's performance.

[0003] Utility model patent CN219641865U discloses a bridge rectifier test holder, including a test holder body. A connecting lug is fixedly installed on one side of the test holder body. A bridge rectifier body is arranged inside the test holder body. A limit component is provided on one side of the test holder body. The limit component includes a threaded rod. A mounting plate is provided at one end of the threaded rod. An internal thread corresponding to the threaded rod is opened inside the test holder body. The threaded rod is rotatably connected to the test holder body through the thread. A buffer component is provided on one side of the mounting plate. The buffer component includes a buffer rod. One end of the buffer rod is fixedly connected to one side of the mounting plate. A limit plate is fixedly installed at the other end of the buffer rod. A buffer spring is sleeved on the surface of the buffer rod.

[0004] In the process of developing this application, the following problems were discovered with this technology: When using the limiting component to limit the bridge rectifier body in the above patent documents, it is fixed and clamped from both sides. Once bridge rectifier bodies of different sizes are clamped, there may be gaps between the front and rear sides of the bridge rectifier body and the test base. During the test, it is necessary to adjust the position or angle of the test base to ensure good contact between the bridge rectifier and the test equipment. This is because adjusting the angle of the bridge rectifier test base during the test can ensure good electrical contact between the bridge rectifier and the test equipment, thereby improving the accuracy and reliability of the test. In the above patent documents, once the bridge rectifier body is tilted, since it is only clamped from both sides, gaps may exist between the front and rear sides of the bridge rectifier body of different sizes and the test base, which may cause the bridge rectifier body to tilt, affecting the test. Therefore, the stability is not good when clamping bridge rectifier bodies of different sizes in different directions.

[0005] Therefore, we propose an adjustable bridge rectifier test fixture. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable bridge rectifier test stand so as to stably clamp bridge rectifier bodies of different sizes in different directions during testing.

[0007] The technical solution adopted in this utility model is as follows:

[0008] An adjustable bridge rectifier test stand includes a base plate, a lifting mechanism, a rotating mechanism, a test base, a bridge rectifier body, a clamping mechanism one, and a clamping mechanism two. The lifting mechanism is disposed on the upper surface of the base plate, the rotating mechanism is disposed on the right side of the lifting mechanism, and the right side of the rotating mechanism is connected to the test base. There are two clamping mechanisms one, and the two clamping mechanisms one are symmetrically disposed on the front and rear sides of the test base. The bridge rectifier body is disposed inside the test base.

[0009] The clamping mechanism two includes a motor two, which is fixedly connected to the outer surface of the lower right side of the test base. A lead screw two is installed at the output end of the motor two. The end of the lead screw two away from the motor two is rotatably connected to the inner left side wall of the test base through a bearing. The lead screw two has two threaded sections with opposite directions of rotation. Two rectangular clamping plates are threadedly connected to the outer surface of the lead screw two, and the two rectangular clamping plates are respectively located on the threaded sections with opposite directions of rotation. An overlapping plate is fixedly connected to the middle of the side of the two rectangular clamping plates that are close to each other. A rubber pad two is adhered to the outer surface of the rectangular clamping plates at the upper end of the overlapping plate.

[0010] The clamping mechanism includes a rotating block and a threaded rod. The outer surface of the threaded rod is threadedly connected to the side wall of the test base. A circular clamping plate is fixedly connected to one end of the threaded rod that extends into the interior of the test base. The other end of the threaded rod that extends outside the test base is fixedly connected to the rotating block. A rubber pad is adhered to the side of the circular clamping plate away from the threaded rod.

[0011] In a preferred embodiment of the utility model, the lifting mechanism includes a vertical plate, which is fixedly connected to the upper surface of the base plate. A side groove is formed on the right side of the vertical plate, and a guide groove is formed on the inner wall of the side groove. A motor is fixedly connected to the inner wall of the top of the side groove, and a lead screw is fixedly connected to the output end of the lower surface of the motor. The end of the lead screw away from the motor is fixedly connected to the inner wall of the bottom of the side groove through a bearing.

[0012] In a preferred embodiment of the utility model, the rotating mechanism includes a movable plate, which is threadedly connected to the outer surface of the lead screw, and the outer surface of the left end of the movable plate is slidably connected to the inner surface of the guide groove. A motor is fixedly connected to the right side of the movable plate, and a rotating rod is installed at the output end of the right side of the motor. The end of the rotating rod away from the motor is fixedly connected to the test base.

[0013] In a preferred embodiment of the utility model, a guide groove is provided on the inner bottom surface of the test base.

[0015] In a preferred embodiment of the invention, the input terminals of motor three and motor two are electrically connected to an external power source.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] In this invention, when testing the bridge rectifier body using this device, the bridge rectifier body needs to be placed inside the test base first. Then, the motor is started to rotate the lead screw. At this time, the two rectangular clamping plates will move closer to each other under the action of the lead screw, thereby causing the two rubber pads to press tightly against the left and right sides of the bridge rectifier body to clamp it. The lower surface of the bridge rectifier body can also overlap the upper surface of the overlapping plate. At the same time, rotating the two rotating blocks can cause the threaded rod to move the circular clamping plate and the rubber pads towards the front and rear sides of the bridge rectifier body until the rubber pads are in close contact with the front and rear sides of the bridge rectifier body, thus achieving clamping of bridge rectifier bodies of different sizes in different directions. When the test base and bridge rectifier body are tilted by the rotating mechanism for subsequent testing, the bridge rectifier body can be stably clamped continuously. Through the cooperation of the above structures, bridge rectifier bodies of different sizes can be stably clamped in different directions during testing. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The following will combine Figures 1-4 A detailed description is provided of an adjustable bridge rectifier test fixture according to an embodiment of this utility model. Example

[0025] Reference Figures 1-4An adjustable bridge rectifier test stand includes a base plate 1, a lifting mechanism 2, a rotating mechanism 3, a test base 4, a bridge rectifier body 5, a first clamping mechanism 6, and a second clamping mechanism 7. The lifting mechanism 2 is located on the upper surface of the base plate 1, and the rotating mechanism 3 is located on the right side of the lifting mechanism 2. The right side of the rotating mechanism 3 is connected to the test base 4. There are two first clamping mechanisms 6, which are symmetrically arranged on the front and rear sides of the test base 4. The bridge rectifier body 5 is located inside the test base 4. The second clamping mechanism 7 includes a second motor 71, which is fixedly connected to the lower right outer surface of the test base 4. A second lead screw 72 is installed at the output end of the second motor 71. The end of the second lead screw 72 away from the second motor 71 is rotatably connected to the left inner wall of the test base 4 through a bearing. The second lead screw 72 has two threaded sections with opposite directions of rotation. Two rectangular clamping plates 73 are threadedly connected to the outer surface of the second lead screw 72, and the two rectangular clamping plates 73 are located on the threaded sections with opposite directions of rotation. The two rectangular clamping plates 73 are close to each other. A lap plate 75 is fixedly connected to the middle of one side, and a rubber pad 76 is glued to the outer surface of the rectangular clamping plate 73 at the upper end of the lap plate 75. A guide groove 41 is opened on the inner bottom surface of the test base 4, and a limiting slide plate 74 is fixedly connected to the lower surface of the rectangular clamping plate 73, and the lower outer surface of the limiting slide plate 74 is slidably connected to the inner surface of the guide groove 41. Specifically, when using this device to test the bridge rectifier body 5, the bridge rectifier body 5 needs to be placed inside the test base 4 first, and then the motor 71 is started to make the lead screw... When screw 72 rotates, the two rectangular clamping plates 73 will move closer to each other under the action of screw 72. The moving rectangular clamping plates 73 will also cause the lower outer surface of the limiting slide plate 74 to slide on the inner surface of the guide groove 41, so as to prevent the rectangular clamping plates 73 from rotating in the same direction with screw 72. This will cause the two rubber pads 76 to be in close contact with the left and right sides of the bridge rectifier body 5, so as to clamp the bridge rectifier body 5. The lower surface of the bridge rectifier body 5 can also overlap the upper surface of the overlapping plate 75.

[0026] Reference Figures 1-4The clamping mechanism 6 includes a rotating block 61 and a threaded rod 62. The outer surface of the threaded rod 62 is threadedly connected to the side wall of the test base 4. A circular clamping plate 63 is fixedly connected to one end of the threaded rod 62 that extends into the test base 4, and a rotating block 61 is fixedly connected to the other end of the threaded rod 62 that extends outside the test base 4. A rubber pad 64 is adhered to the side of the circular clamping plate 63 away from the threaded rod 62. Specifically, rotating the two rotating blocks 61 can cause the threaded rod 62 to move the circular clamping plate 63 and the rubber pad 64 closer to the front and rear sides of the bridge rectifier body 5 until the rubber pad 64 is in close contact with the front and rear sides of the bridge rectifier body 5, thereby achieving clamping of bridge rectifier bodies 5 of different sizes in different directions. When the test base 4 and the bridge rectifier body 5 are tilted by the rotating mechanism 3 for subsequent testing, the bridge rectifier body 5 can be stably clamped continuously. Through the cooperation of the above structures, bridge rectifier bodies 5 of different sizes can be stably clamped in different directions during testing.

[0027] Reference Figures 1-4 The lifting mechanism 2 includes a vertical plate 21, which is fixedly connected to the upper surface of the base plate 1. A side groove 22 is provided on the right side of the vertical plate 21, and a guide groove 25 is provided on the inner wall of the side groove 22. A motor 23 is fixedly connected to the inner wall of the top of the side groove 22, and a lead screw 24 is fixedly connected to the output end of the lower surface of the motor 23. The end of the lead screw 24 away from the motor 23 is fixedly connected to the inner wall of the bottom of the side groove 22 through a bearing. Specifically, when it is necessary to adjust the height of the test base 4 and the bridge rectifier body 5, the motor 23 can be started to rotate the lead screw 24. At this time, the moving plate 31 will move upward under the rotation of the lead screw 24, and the left end of the moving plate 31 will slide on the inner surface of the guide groove 25 to guide the movement trajectory of the moving plate 31. Then, the motor 32 and the rotating rod 33 drive the test base 4 and the bridge rectifier body 5 to move upward or downward to adjust the test height.

[0028] Reference Figures 1-4 The rotating mechanism 3 includes a movable plate 31, which is threadedly connected to the outer surface of the lead screw 24. The outer surface of the left end of the movable plate 31 is slidably connected to the inner surface of the guide groove 25. A motor 32 is fixedly connected to the right side of the movable plate 31. A rotating rod 33 is installed at the output end of the right side of the motor 32. The end of the rotating rod 33 away from the motor 32 is fixedly connected to the test base 4. The input end of the motor 32 is electrically connected to an external power supply. Specifically, when it is necessary to tilt the test base 4 and the bridge rectifier body 5, the motor 32 can be started to make the rotating rod 33 drive the test base 4 and the bridge rectifier body 5 to tilt. At this time, the clamping mechanism 6 and the clamping mechanism 7 can stably clamp the bridge rectifier body 5 from different directions.

[0029] The implementation principle of an adjustable bridge rectifier test fixture embodiment of this application is as follows:

[0030] When using this device, first connect an external power source. When testing the bridge rectifier body 5 using this device, first place the bridge rectifier body 5 inside the test base 4. Then start motor 71 to rotate lead screw 72. At this time, the two rectangular clamping plates 73 will move closer to each other under the rotation of lead screw 72. The moving rectangular clamping plates 73 will also cause the lower outer surface of the limiting slide plate 74 to slide on the inner surface of guide groove 41, preventing the rectangular clamping plates 73 from rotating in the same direction as lead screw 72. This causes the two rubber pads 76 to press tightly against the left and right sides of the bridge rectifier body 5, thus clamping the bridge rectifier body 5. The lower surface can also overlap the upper surface of the overlapping plate 75; at the same time, rotating the two rotating blocks 61 can cause the threaded rod 62 to drive the circular clamping plate 63 and the rubber pad 64 to move closer to the front and rear sides of the bridge rectifier body 5 until the rubber pad 64 is in close contact with the front and rear sides of the bridge rectifier body 5, so as to clamp the bridge rectifier body 5 of different sizes in different directions. When the rotating mechanism 3 is used to drive the test base 4 and the bridge rectifier body 5 to tilt for testing, the bridge rectifier body 5 can be stably clamped continuously. Through the cooperation of the above structures, the bridge rectifier body 5 of different sizes can be stably clamped in different directions during testing.

[0031] On the other hand, when it is necessary to adjust the height of the test base 4 and the bridge rectifier body 5, the motor 23 can be started to rotate the lead screw 24. At this time, the moving plate 31 will move upward under the rotation of the lead screw 24. At the same time, the left end of the moving plate 31 will slide on the inner surface of the guide groove 25 to guide the movement trajectory of the moving plate 31. Then, the motor 32 and the rotating rod 33 will drive the test base 4 and the bridge rectifier body 5 to move upward or downward to adjust the test height. When it is necessary to tilt the test base 4 and the bridge rectifier body 5, the motor 32 can be started to rotate the rod 33 to tilt the test base 4 and the bridge rectifier body 5. At this time, the clamping mechanism 6 and the clamping mechanism 7 can stably clamp the bridge rectifier body 5 from different directions.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
