Description

Technical Field

[0001] The utility model relates to the field of electrical component processing, in particular to a clamping and fixing device for electrical components. Background Art

[0002] Electrical components refer to various components and parts that play a key role in electrical equipment. They are the basis of electrical systems. In China, the manufacture and use of electrical components are subject to strict standards and regulations to ensure the safety, reliability and efficiency of electrical equipment. Therefore, during the production and processing of electrical components, they need to be inspected, quality controlled, and reprocessed. In this process, clamping devices are needed.

[0003] The utility model patent with publication number CN220007492U discloses a component clamping device, including a mounting seat, a clamping base is installed on the upper side of the mounting seat, a first bolt is installed between the mounting seat and the clamping base, a first gripper is fixed on the upper side of the clamping base, a second gripper is slidably engaged with the upper side of the clamping base, a rotating clamping hand is rotatably engaged with the second gripper, a clamping block is fixed to one end of the first gripper and one end of the rotating clamping hand, a threaded rod is threadedly engaged with one side of the clamping base, the threaded rod corresponds to the second gripper, and a collection box is slidably engaged in the mounting seat.

[0004] The utility model can ensure that the vertical positions of the two clamping blocks remain unchanged through the above design, thereby expanding the scope of application of the gear parts and clamping the parts more firmly. A rotating clamping hand is installed on the second gripper, and the angle of one of the clamping blocks can be changed by changing the angle of the rotating clamping hand, so that the curved special-shaped parts can be clamped. However, the prior art still has room for improvement:

[0005] 1. In the above-mentioned prior art, the first gripper is fixed on the base, and clamping can only be achieved by controlling the second gripper to approach the first gripper. Such a design limits the flexibility and diversity of the clamped object, especially when symmetrical or balanced clamping is required. This unilateral motion design may not meet the requirements. And in the case of unilateral drive, the clamping force may produce a large torque on one side of the clamping block, resulting in unstable clamping or uneven pressure on the clamped object. This uneven force distribution may cause the object to slip or be damaged during the clamping process. Therefore, the structure is not stable enough and needs to be improved.

[0006] 2. In the above-mentioned prior art, although the special-shaped parts can be clamped by installing a rotating clamp, the shape of the clamping surface of the rotating clamp is ultimately unchanged, which results in the clamping area of ​​the clamping surface changing when facing special-shaped parts of different shapes. For some parts with special shapes, the clamping surface may not provide sufficient contact area, resulting in unstable clamping, and even sliding or loosening, affecting the normal operation of the equipment.

[0007] In view of this, it is necessary to improve the above defects. Utility Model Content

[0033] 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. 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.

[0034] Embodiment 1:

[0035] like Figure 1 , Figure 2 , Figure 5 As shown, the present embodiment proposes a clamping and fixing device for electrical components, which mainly includes a base plate 1, a motor 3, a clamping drive assembly 7 and a clamping block 13, wherein the base plate 1 is distributed in a state of being wide at the rear and pointed at the front, and a slide groove 2 is opened in the middle of the front end of the base plate 1; the motor 3 is fixedly connected to one side of the rear portion of the top end of the base plate 1, and its function is to provide a certain power for the clamping and driving assembly 7. Specifically, a screw rod 4 is fixedly connected to the output shaft of the motor 3, a threaded block 5 is threadedly connected to the screw rod 4, and a sliding limit portion 6 is fixedly connected to the bottom end of the threaded block 5, and the sliding limit portion 6 is slidably connected to the inside of the slide groove 2; when the motor 3 is powered on and driven, its output shaft will drive the screw rod 4 to rotate, and under the influence of the threaded connection, the screw rod 4 will drive the threaded block 5 to move thereon, and the sliding limit portion 6 at the bottom end of the threaded block 5 will slide inside the slide groove 2, providing support for the threaded block 5 while also limiting its displacement in other directions, ensuring that it can move stably on the screw rod 4.

[0036] The clamping drive assembly 7 includes a fixed base 8 fixedly connected to both sides of the top of the bottom plate 1, the top of the fixed base 8 is rotatably connected to a connecting rod 1 9, the front end of the connecting rod 1 9 is rotatably connected to a connecting rod 2 10, the front end of the connecting rod 2 10 is provided with a connecting rod 3 11, the connecting rod 3 11 and the side of the connecting rod 2 10 away from the thread block 5 are both rotatably connected to a connecting rod 4 12, and at the same time, the proximal ends of the connecting rod 2 10 on both sides are both rotatably connected to the thread block 5, and the proximal ends of the connecting rod 3 11 on both sides are both rotatably connected to the thread block 5. Therefore, when the thread block 5 moves, it will drive the connecting rod 2 10 and the connecting rod 3 11 to rotate, and under the action of the lever principle, the other end of the connecting rod 2 10 will move in the opposite direction, thereby changing its position with the connecting rod 4 12, so that the front ends of the connecting rod 4 12 are close to each other, achieving the clamping effect.

[0037] The clamping block 13 is fixedly connected to the front end of the adjacent sides of the connecting rod four 12 on both sides. The front ends of the clamping blocks 13 on both sides are provided with a plurality of replaceable special-shaped clamping parts 14 of different shapes.

[0038] Embodiment 2:

[0039] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0040] like Figure 1 , Figure 2 , Figure 4 As shown, this embodiment proposes a clamping and fixing device for electrical components, the top end of the fixed base 8 is fixedly connected with an insertion shaft 16; the insertion shaft 16 is inserted into the connecting rod 1 9; the front end of the connecting rod 1 9 is inserted with an insertion shaft 2 17, and the insertion shaft 2 17 is inserted into the connecting rod 2 10; the separated ends of the connecting rods 2 10 on both sides are inserted with insertion shafts 3 18, and the insertion shaft 3 18 is inserted into the connecting rod 4 12; the separated ends of the connecting rods 3 11 on both sides are inserted with insertion shafts 4 19, and the insertion shaft 4 19 is inserted into the connecting rod 4 12.

[0041] Embodiment 3:

[0042] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

However, this does not mean that the above-mentioned components do not exist in the utility model, nor can it be interpreted as a practical limitation on the utility model.

[0046] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
