Description

Technical Field

[0002] In circuit experiments, clamping mechanisms are often used to hold and fix the circuit board in order to ensure that the experimenters can work stably. However, the existing clamping mechanisms for circuit boards are too uniform in specifications, while the shapes and sizes of circuit boards are diverse. This makes the clamping effect less than ideal when clamping irregularly shaped circuit boards. In addition, the clamped circuit board is inconvenient to operate during circuit experiments, and the experimenters need to constantly change their position, which affects the efficiency of the experiment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a clamping mechanism for operating circuit experimental boards, which clamps the circuit experimental boards at multiple angles according to their shape, thereby improving the stability of the clamping.

[0005] Furthermore, the guide groove is a straight groove and has a certain angle with the axis of the slide groove.

[0006] Furthermore, a limiting plate is provided at one end of the clamping rod away from the middle of the clamping base, and an elastic element is disposed between the limiting plate and the baffle. The elastic element can extend and retract along the clamping rod.

[0007] Furthermore, a rubber plate is fixedly connected to one end of the clamping rod near the middle of the clamping base.

[0008] Furthermore, the clamping mechanism also includes a base plate and a rotating assembly; the mounting plate is rotatably connected to the base plate via the rotating assembly.

[0009] Furthermore, the rotary assembly includes a gear ring fixed on the base plate, a rotating ring located inside the gear ring and rotatably connected thereto, a transmission gear meshing with the outer teeth of the gear ring, and a servo motor; a mounting plate is fixedly mounted on the rotating ring; the transmission gear is mounted on the mounting plate, and the servo motor drives the transmission gear to rotate so that it makes a circular motion around the gear ring, thereby driving the mounting plate to rotate.

[0010] Furthermore, both the guide base and the clamping base have a circular groove in the middle, and a fixed post is provided in the circular groove. One end of the fixed post clamping base is fixedly connected to a placement plate for placing the circuit experimental board, and the other end of the fixed post is fixedly connected to the mounting plate; the clamping base and the fixed post are rotatably connected.

[0011] Furthermore, the drive assembly includes an output cylinder, a cylinder mounting base, and a connecting rod; the output cylinder is hinged to the mounting plate via the cylinder mounting base, one end of the connecting rod is fixedly connected to the output shaft of the output cylinder, and the other end of the connecting rod is hinged to the clamping base; the output cylinder drives the connecting rod to perform linear reciprocating motion, thereby pushing the clamping base to rotate relative to the guide base.

[0012] Furthermore, the output cylinder is fixedly connected to a support plate, and the support plate is slidably connected to the mounting plate.

[0013] Furthermore, the mounting plate is provided with a moving groove along the moving trajectory of the support plate, and the support plate is embedded in the moving groove and slidably connected to the mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model features a baffle that can slide along a groove on a clamping base, clamping rods that slide along the baffle under the action of an elastic element, and a guide groove on a guide base. When the clamping base rotates relative to the guide base, multiple guide rollers move within the guide groove, causing multiple baffles to move radially synchronously. Simultaneously, after multiple clamping rods contact different positions of the experimental circuit board, the multiple clamping rods move synchronously or independently relative to their respective baffles and clamp the circuit experimental board under the action of the elastic element. The clamping rods that can move individually or synchronously in different positions break the limitations of traditional single-specification clamping and can adapt to multiple angles according to the irregular shape of the circuit experimental board, solving the problem of difficult clamping of irregularly shaped boards.

[0015] 2. The elastic element between the baffle and the clamping rod in this utility model allows the rubber plate to fit tightly against the surface of the experimental board, preventing damage to the board caused by rigid clamping. Multiple gripper modules work together to apply a stable clamping force to the circuit experimental board from different directions, preventing the board from shaking during the experiment and ensuring operational accuracy.

[0016] 3. The mounting plate of this utility model can be rotatably connected to the base plate through a rotating component, so that the circuit experimental board can rotate relative to the base plate while being clamped. Experimenters can obtain the best operating view without moving their own position, reducing wasted operation actions and improving experimental efficiency.

[0017] 4. Both the guide base and the clamping base of this utility model have a circular groove in the middle. A fixed column is fixedly connected to the mounting plate in the circular groove. The clamping base rotates around the fixed column to ensure the stability of the clamping base rotation and to ensure the smoothness of the entire clamping process.

[0018] 5. The output cylinder of this utility model drives the clamping base to rotate through the connecting rod, replacing the traditional manual adjustment method, reducing manpower consumption, and the adjustment process is stable and precise, which can quickly and smoothly realize the clamping action of the circuit experimental board.

[0019] 6. This utility model uses a support plate to support the output cylinder, ensuring the stability of the output cylinder, reducing the shaking when the output cylinder moves, and preventing the shaking from affecting the clamping effect. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] This utility model provides a clamping mechanism for operating a circuit experimental board, such as... Figure 1 As shown, the clamping mechanism includes a base plate 1, a mounting plate 11, a clamping assembly 2, a drive assembly 3, and a rotary assembly. The mounting plate 11 is rotatably connected to the base plate 1 via the rotary assembly; the clamping assembly 2 and the drive assembly 3 are mounted on the mounting plate 11.

[0028] like Figure 2 , 3 As shown, the clamping assembly 2 includes a guide base 21, a clamping base 22, and gripper modules. The guide base 21 is fixed on the mounting plate 11 and has two or more guide grooves 23. The clamping base 22 is rotatably connected to the guide base 21. The circuit experimental board is placed in the middle of the clamping base 22. Two or more sliding grooves 28 are radially arranged around the middle of the clamping base 22, that is, the two or more sliding grooves 28 are arranged radially around the middle of the clamping base 22. In addition, the sliding grooves 28 penetrate the clamping base 22 along the line connecting the guide base 21 and the clamping base 22. Two or more gripper modules are arranged radially on the clamping base 22.

[0029] The gripper module includes a baffle 29, a guide roller 26, and a gripper rod 210. The baffle 29 is slidably connected to the slide groove 28, and the bottom of the baffle 29 is rotatably connected to the guide roller 26. The guide roller 26 extends out of the slide groove 28 and is slidably connected to the guide groove 23. The top of the baffle 29 extends out of the slide groove 28, and the gripper rod 210 passes through the protruding part of the baffle 29 radially (radial means along the axis of the slide groove 28) and is slidably connected to it. An elastic element is provided between the gripper rod 210 and the baffle 29.

[0030] The drive assembly 3 is used to drive the clamping base 22 to rotate relative to the guide base 21 around the middle of the clamping base 22, so that the guide roller 26 moves in the guide groove 23, drives the baffle 29 to move in the slide groove 28, thereby driving the clamping rod 210 to move radially, and the clamping rod 210 clamps and releases the circuit experimental board under the action of the elastic force of the elastic element.

[0031] In this embodiment, two or more clamping rods 210 are arranged radially, and the clamping rods 210 move radially relative to the baffle 29 via elastic elements. While the clamping base 22 rotates, the positions of the two or more clamping rods 210 are adjusted synchronously or independently, enabling multi-directional adaptation to the irregular shape of the experimental board and solving the problem of difficult clamping of irregularly shaped boards. Simultaneously, the clamping rods 210 in different positions apply stable clamping forces to the circuit experimental board from different directions, preventing board shaking during the experiment and ensuring operational accuracy.

[0032] In this embodiment, the guide groove 23 is a straight groove and has a certain angle with the sliding groove 28. When the clamping base 22 rotates relative to the guide base 21, the guide roller 26 moves linearly along the guide groove 23, which has a certain angle with the sliding groove 28 (radial direction of the clamping base 22). This causes the guide roller 26 to move radially relative to the center of the clamping base 22, thereby driving the baffle 29 to move radially within the sliding groove 28. Under the premise that the clamping base 22 rotates relative to the guide base 21 at the same speed, the speed at which the guide roller 26 moves radially relative to the center of the clamping base 22 can be adjusted by setting the angle between the guide groove 23 and the sliding groove 28.

[0033] In a specific implementation, as the guide roller 26 moves from one end of the guide groove 23 to the other end, the movement trajectory of the baffle 29 is entirely within the slide groove 28. In some embodiments, when the guide roller 26 is located at one end of the guide groove 23, the baffle 29 is located at one end of the slide groove 28; and when the guide roller 26 is located at the other end of the guide groove 23, the baffle 29 is located at the other end of the slide groove 28.

[0034] In this embodiment, as Figure 3 As shown, a clamping moving block 27 is connected to one end of the baffle 29 facing the guide base 21. The clamping moving block 27 is located in the slide groove 28 and can move along the slide groove 28. One end of the guide roller 26 is rotatably connected to the clamping moving block 27 through a bearing, and the other end of the guide roller 26 is located in the guide groove 23 and can move along the guide groove 23.

[0035] In some embodiments, a limiting plate 213 is provided at one end of the clamping rod 210 away from the middle of the clamping base 22, and an elastic element is disposed between the limiting plate 213 and the baffle 29, and the elastic element can extend and retract along the clamping rod 210. As an improvement, a rubber plate 212 is fixedly connected to one end of the clamping rod 210 near the middle of the clamping base 22.

[0036] Specifically, the baffle 29 is slidably connected to the clamping rod 210. A limiting plate 213 is placed at one end of the clamping rod 210 away from the center of the clamping base 22 to prevent the clamping rod 210 from falling off the baffle 29. A spring 211 is wound around the surface of the clamping rod 210, with both ends of the spring 211 fixed to the baffle 29 and the limiting plate 213, respectively. When two or more baffles 29 move simultaneously toward the center of the clamping base 22 (circuit test board) within their respective sliding grooves 28, they drive the corresponding clamping rods 210 to move in the same direction. After the rubber plates 212 on the clamping rods 210 at different positions contact different parts of the circuit test board, the springs 211 are compressed. Simultaneously, the elastic force of the springs 211 allows the rubber plates 212 to tightly adhere to the circuit test board, thereby clamping the circuit test board.

[0037] Two or more radially arranged clamping rods 210 allow for multi-directional clamping of the circuit experimental board, making it suitable for circuit experimental boards of different shapes. Furthermore, the adaptability to the circuit experimental board can be further enhanced by incorporating springs 211.

[0038] The guide base 21 is fixed on the mounting plate 11, serving to position and guide the movement of the guide roller 26. In this embodiment, both the guide base 21 and the clamping base 22 have a circular groove 24 in the middle, and a fixed post 251 is provided in the circular groove 24. A placement plate 25 is fixedly connected to one end of the fixed post 251 near the clamping base 22. The placement plate 25 is used to place the circuit experimental board, and the other end of the fixed post 251 is fixedly connected to the mounting plate 11. The clamping base 22 and the fixed post 251 are rotatably connected, that is, the clamping base 22 rotates around the fixed post 251.

[0039] In some embodiments, such as Figure 5 As shown, the rotary assembly includes a gear ring 38 fixed on the base plate 1, a rotating ring 39 located inside the gear ring 38 and rotatably connected thereto, a transmission gear 37 meshing with the outer teeth of the gear ring 38, and a servo motor 36. The mounting plate 11 is fixedly mounted on the rotating ring 39; the transmission gear 37 is mounted on the mounting plate 11, and the servo motor 36 drives the transmission gear 37 to rotate so that it makes a circular motion around the gear ring 38, thereby causing the mounting plate 11 to rotate relative to the base plate 1.

[0040] In other words, the clamping component 2 mounted on the mounting plate 11 can rotate relative to the base plate 1, meaning the circuit experimental board held by the clamping component 2 can rotate relative to the base plate 1, providing the circuit experimental board with a degree of freedom of rotation. It can rotate while being clamped, allowing the experimenter to obtain the optimal operating view without moving their own position, reducing wasted operational actions and improving experimental efficiency. In some embodiments, such as Figure 4 As shown, the drive assembly 3 includes an output cylinder 33, a cylinder mounting base 34, a hinge base 31, and a connecting rod 32. The output cylinder 33 is hinged to the mounting plate 11 via the cylinder mounting base 34. One end of the connecting rod 32 is fixedly connected to the output shaft of the output cylinder 33, and the other end of the connecting rod 32 is hinged to the clamping base 22 via the hinge base 31. The output cylinder 33 drives the connecting rod 32 to perform linear reciprocating motion, thereby pushing the clamping base 22 to rotate relative to the guide base 21.

[0041] As an improvement, the output cylinder 33 is fixedly connected to a support plate 35, and the support plate 35 is slidably connected to the mounting plate 11. As a further improvement, the mounting plate 11 is provided with a moving groove along the moving trajectory of the support plate 35, and the support plate 35 is embedded in the moving groove and slidably connected to the mounting plate 11.

[0042] The working principle of this invention is as follows: The circuit experimental board is placed in the middle of the clamping base 22. The clamping base 22 has two or more radially arranged sliding grooves 28 around the circuit experimental board. The guide base 21 has a corresponding sliding groove 23 with a certain angle to the sliding grooves 28. When the clamping base 22 rotates relative to the guide base 21, the guide roller 26 moves along the sliding groove 23, driving the baffle 29 to move along the sliding groove 28, thereby driving the clamping rod 210 to move along the sliding groove 28. When the rubber plate 212 on the clamping rod 210 contacts the circuit experimental board, the spring 211 is compressed to generate elastic force. The elastic force of the spring 211 allows the rubber plate 212 to fit tightly against the surface of the experimental board, thereby clamping the circuit experimental board. This design can adapt to circuit experimental boards of different shapes and sizes, thus achieving more flexible and precise clamping. In addition, the mounting plate 11 can rotate relative to the base plate 1, providing an additional degree of rotational freedom for the entire clamping mechanism. While the circuit experimental board is being clamped, the circuit experimental board can also be rotated by rotating the mounting plate 11, further facilitating the experimenter to adjust the orientation of the experimental board.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
