Description

Technical Field

[0001] This utility model belongs to the field of EMC bracket technology, and in particular relates to an EMC bracket pin bending angle adjustment device. Background Technology

[0002] EMC brackets are metal components used to support and secure electronic components or circuit boards. Their primary purpose is to provide sufficient mechanical support while meeting electromagnetic compatibility (EMC) testing requirements. In EMC testing, bracket design must consider the electrical performance of the pins, thermal management, and electromagnetic interactions with the device.

[0003] In current technology, the pins of EMC brackets usually need to be manually bent to meet different working environments or usage requirements. Since this process is manual, it is often impossible to ensure that the bending angle of all pins is completely consistent. This results in a certain difference in the bending angle of each pin. This inconsistency not only affects the overall stability of the bracket, but may also have a negative impact on the performance and reliability of the equipment. Therefore, we propose a pin bending angle adjustment device for EMC brackets. Utility Model Content

[0004] The purpose of this invention is to provide a pin bending angle adjustment device for an EMC bracket. Through the design of components such as the electric telescopic rod, rotating gear, and bending plate of the bending mechanism, the problems of low bending accuracy and inconvenient adjustment in the prior art are solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a pin bending angle adjustment device for an EMC bracket, including a base, a support frame fixedly connected to the top of the base, a positioning frame fixedly connected to the top of the base, and a bending mechanism provided on the top of the base. The bending mechanism includes an electric telescopic rod, which is fixedly connected to the bottom of the positioning frame. A fixing plate is fixedly connected to the telescopic end of the electric telescopic rod, and a connecting plate is fixedly connected to the side of the fixing plate. A rack is fixedly connected to the end of the connecting plate away from the telescopic end of the electric telescopic rod. A support shaft is rotatably connected inside the base. A rotating gear is fixedly passed through the circumferential surface of the support shaft, and a bending plate is fixedly connected to the circumferential surface of the support shaft. The purpose of this mechanism is to adjust the angle of the pins on the bracket so as to more accurately test, debug, or fix the equipment.

[0006] Furthermore, the number of support shafts is set to four, in pairs, and symmetrical to each other along the vertical central axis of the base. The purpose is to ensure torque balance during the bending process, prevent the support from tilting or bending asymmetrically, thereby improving bending accuracy and stability.

[0007] Furthermore, a gear one is fixedly connected to the circumferential surface of one support shaft, and a gear two is fixedly connected to the circumferential surface of another support shaft, ensuring that the four support shafts can rotate synchronously.

[0008] Furthermore, a compression spring is fixedly connected to the bottom of the fixing plate, and a pressing plate is elastically connected to the fixing plate through the compression spring. The purpose of this is to ensure that the pressing plate can stably press the EMC bracket.

[0009] Furthermore, the rack meshes with the rotating gear, and gear one meshes with gear two. The purpose of this is to ensure that the movement of the rack can drive the rotating gear to rotate, and to ensure that the rotation of gear one can drive gear two to rotate.

[0010] Furthermore, a feeding mechanism is provided on the top of the base. The feeding mechanism includes a sliding groove, which is opened on the top of the base. A pushing inclined plate is slidably connected inside the sliding groove. A push rod is fixedly connected to the side of the rack. The purpose of the feeding inclined groove on the top of the base is to ensure that the bent EMC bracket can be automatically fed, reducing manual operation.

[0011] Furthermore, a return spring is fixedly connected inside the sliding groove. The end of the return spring away from the sliding groove is fixedly connected to the bottom of the pushing inclined plate. The purpose of this is to ensure that the pushing inclined plate can automatically reset and reduce manual intervention.

[0012] Furthermore, the bottom of the pushing ramp is located on the displacement trajectory of the push rod, the purpose of which is to ensure that the movement of the push rod can push the pushing ramp.

[0013] Furthermore, the pushing inclined plate is located to the left of the unloading chute. Its purpose is to ensure that the bent EMC bracket can be smoothly pushed into the unloading chute and slide out along the chute through the inclined surface design of the inclined plate, thereby realizing automatic unloading and avoiding jamming.

[0014] Furthermore, the number of reset springs is set to several and arranged linearly along the inside of the sliding groove. The purpose is to distribute the reset force evenly through the synergistic effect of multiple springs, ensuring the smooth reset of the inclined plate in the sliding groove, improving reset efficiency and consistency, and thus preparing for the next operation.

[0015] This utility model has the following beneficial effects: 1. This utility model utilizes the interplay between components such as the electric telescopic rod, rotating gear, and bending plate of the bending mechanism to place the EMC bracket on the positioning frame. The electric telescopic rod drives the fixed plate to move downward, causing the rack and pinion to mesh with the rotating gear, which in turn drives the support shaft to rotate. The bending plate completes a precise bend, and the pressing plate prevents the bracket from slipping. Gear one and gear two transmit synchronously, ensuring that the bending plates on both sides bend synchronously, thus improving bending accuracy and stability.

[0016] 2. This utility model utilizes the cooperation between components such as the pushing inclined plate, push rod, and feeding chute of the feeding mechanism. After bending, the electric telescopic rod resets, drives the push rod upward, pushes the inclined plate to overcome the elastic force of the return spring, and pushes the bent EMC bracket into the feeding chute, automatically completing the feeding. When the electric telescopic rod descends again, the push rod separates and pushes the inclined plate, and the return spring drives the inclined plate to automatically reset, preparing for the next operation. This design improves feeding efficiency and automation.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] Please see Figures 1-5 This utility model is a pin bending angle adjustment device for an EMC bracket, including a base 1, a support frame 2 fixedly connected to the top of the base 1, a positioning frame 3 fixedly connected to the top of the base 1, and a bending mechanism 4 provided on the top of the base 1. The bending mechanism 4 includes an electric telescopic rod 41, which is fixedly connected to the bottom of the positioning frame 3. A fixing plate 47 is fixedly connected to the telescopic end of the electric telescopic rod 41. A connecting plate 42 is fixedly connected to the side of the fixing plate 47. A rack 43 is fixedly connected to the end of the connecting plate 42 away from the telescopic end of the electric telescopic rod 41. A support shaft 44 is rotatably connected inside the base 1. A rotating gear 45 is fixedly passed through the circumferential surface of the support shaft 44. A bending plate 46 is fixedly connected to the circumferential surface of the support shaft 44. The purpose of this is to adjust the angle of the pins on the bracket so as to more accurately test, debug or fix the equipment.

[0023] There are four support shafts 44, arranged in pairs and symmetrically arranged along the vertical central axis of the base 1. The purpose is to ensure torque balance during the bending process, prevent the support from tilting or bending asymmetrically, thereby improving bending accuracy and stability.

[0024] Gear 48 is fixedly connected to the circumferential surface of the support shaft 44, and gear 49 is fixedly connected to the circumferential surface of the other support shaft 44. The purpose is to ensure that the four support shafts 44 can rotate synchronously.

[0025] A compression spring 410 is fixedly connected to the bottom of the fixing plate 47. The fixing plate 47 is elastically connected to the pressing plate 411 through the compression spring 410. The purpose is to ensure that the pressing plate 411 can press the EMC bracket stably.

[0026] The rack 43 meshes with the rotating gear 45, and the first gear 48 meshes with the second gear 49. The purpose is to ensure that the movement of the rack 43 can drive the rotating gear 45 to rotate, and to ensure that the rotation of the first gear 48 can drive the second gear 49 to rotate.

[0027] The base 1 is provided with a feeding mechanism 5 on its top. The feeding mechanism 5 includes a sliding groove 51, which is opened on the top of the base 1. A pushing inclined plate 52 is slidably connected inside the sliding groove 51. A push rod 53 is fixedly connected to the side of the rack 43. The base 1 is provided with a feeding inclined groove 54. The purpose is to ensure that the bent EMC bracket can be automatically fed, reducing manual operation.

[0028] A return spring 55 is fixedly connected inside the sliding groove 51. The end of the return spring 55 away from the sliding groove 51 is fixedly connected to the bottom of the push plate 52. The purpose is to ensure that the push plate 52 can automatically reset and reduce manual intervention.

[0029] The bottom of the push plate 52 is located on the displacement trajectory of the push rod 53, the purpose of which is to ensure that the movement of the push rod 53 can push the push plate 52.

[0030] The inclined plate 52 is located to the left of the unloading chute 54. Its purpose is to ensure that the bent EMC bracket can be smoothly pushed into the unloading chute 54 and slide out along the chute through the inclined surface design of the inclined plate, thereby realizing automatic unloading and avoiding jamming.

[0031] The number of reset springs 55 is set to several and arranged in a linear array along the inside of the sliding groove 51. The purpose is to distribute the reset force evenly through the synergistic effect of multiple springs, so as to ensure the smooth reset of the inclined plate 52 in the sliding groove 51, improve the reset efficiency and consistency, and thus prepare for the next operation.

[0032] A specific application of this embodiment is as follows: When it is necessary to bend the pins of the EMC bracket, the EMC bracket is placed on the positioning frame 3, and then the electric telescopic rod 41 is activated. Its telescopic end extends downward, driving the fixing plate 47 to move downward together. The fixing plate 47 drives the rack 43 to move linearly downward in the vertical direction through the connecting plate 42. The downward moving rack 43 meshes with the rotating gear 45, thereby driving the rotating gear 45 to rotate. The rotating gear 45 drives the support shaft 44 to rotate synchronously. The rotation of the support shaft 44 directly drives the bending plate 46 fixed on its circumference to swing. The bending plate 46 rotates from the initial position by a predetermined angle. During this process, its The working surface contacts and presses the pins of the EMC bracket, completing a precise bending action. While the fixing plate 47 moves, it drives the pressing plate 411 to stabilize and fix the EMC bracket during bending to prevent slippage. At the same time, one support shaft 44 meshes with the gear 49 on another support shaft 44 through the gear 48 on it. When one of the rotating gears 45 is driven by the rack 43, the support shaft 44 on that side begins to rotate. Through the meshing transmission of the gear 48 and the gear 49, the support shaft 44 on the symmetrical side is driven to rotate synchronously and in opposite directions. This design ensures that the bending plates 46 on both sides of the device can bend the pins on both sides of the EMC bracket synchronously.

[0033] After the EMC bracket is bent, the electric telescopic rod 41 returns to its original position. As the rack 43 returns to its original position with the extension end of the electric telescopic rod 41, the push rod 53 also moves upward. On the upward displacement trajectory of the push rod 53, its top end will contact and push the bottom of the pushing inclined plate 52. Since the bottom of the pushing inclined plate 52 is located on the displacement trajectory of the push rod 53, the upward movement of the push rod 53 will overcome the elastic force of the return spring 55, pushing the pushing inclined plate 52 to slide upward in the sliding groove 51. The inclined surface of the pushing inclined plate 52 will contact and push the completed... The bent EMC bracket is pushed away from the working position and falls into the unloading chute 54 opened on the base 1. The workpiece slides out along the unloading chute 54, completing the automatic unloading. When the electric telescopic rod 41 moves downward again to perform the next bend, the rack 43 and push rod 53 move downward and separate from the push plate 52. At this time, the compressed return spring 55 releases its elastic potential energy, driving the push plate 52 to slide downward in the sliding groove 51 and automatically return to the initial position, preparing for the next unloading action.
