Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, and particularly relates to a linkage fixture structure. Background Technology

[0002] In the field of electronic component repair and inspection, small precision components (such as chips, circuit board assemblies, Type-C interface modules, etc.) need to be frequently clamped and fixed to ensure the stability of the component position during the repair and inspection process and avoid detection errors or repair mistakes caused by shaking.

[0003] Currently, the mainstream clamping solutions are mainly divided into two categories: one is a manually adjustable independent clamp, which requires the operation of two or more chucks to fix the component. The operation steps are cumbersome, and it is difficult to ensure the consistency of clamping force in multiple directions. Excessive force on one side can easily cause component deformation and pin damage. The other is a pneumatic or electric driven linkage clamp, which can achieve synchronous clamping, but it has a complex structure and large size. It requires an external air source or power source, which cannot meet the needs of "portable mobile operation" in maintenance and inspection scenarios. Moreover, the equipment cost and maintenance cost are high, and it is not suitable for the flexible handling of small batches of multi-specification components.

[0004] Therefore, a new fixture needs to be designed to meet the clamping requirements in the testing and repair process of small electronic components. Utility Model Content

[0005] This utility model provides a linkage clamp structure. The clamp has problems such as cumbersome operation, poor protection of components, and insufficient adaptability and ease of use, making it difficult to efficiently, safely and flexibly meet the clamping needs of small components.

[0006] This utility model is implemented as follows: a linkage clamping structure includes a base plate. A first clamping unit that can slide laterally and a second clamping unit that can slide longitudinally are provided on the upper surface of the base plate. The movement directions of the first clamping unit and the second clamping unit are perpendicular to each other. A placement groove for placing components is formed on the base plate at the intersection of the movement directions of the first clamping unit and the second clamping unit.

[0007] The first clamping unit includes a rotating wheel, and the second clamping unit includes a guide plate extending toward one side of the first clamping unit and inclined forward at its outer end, with the front side of the guide plate contacting the rotating wheel;

[0008] When the first clamping unit is pulled outward, the rotating wheel moves outward and squeezes the guide plate, pushing the second clamping unit to move backward synchronously. The tail of the first clamping unit and the tail of the second clamping unit are respectively provided with elastic elements that drive them to reset and clamp the workpiece in the direction of the placement slot.

[0009] Preferably, the first clamping unit includes a first sliding plate, a first clamp is provided at the head end of the first sliding plate, and an inclined outwardly extending mounting position is provided on the first sliding plate, and the rotating wheel is rotatably disposed at the mounting position.

[0010] Preferably, the second clamping unit includes a second sliding plate, a second chuck is provided at the front end of the second sliding plate, and a positioning groove adapted to the rotating wheel is formed at the connection between the second sliding plate and the guide plate.

[0011] Preferably, a baffle is provided on one side and the rear end of the substrate, a first spring is provided between the tail of the first clamping unit and the baffle, and a second spring is provided between the tail of the second clamping unit and the baffle.

[0012] Preferably, a handle is provided at the rear end of the substrate. Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The linkage clamping structure of this utility model, through the transmission cooperation of the rotating wheel and the guide plate and the spring-driven reset design, only needs to drive the first clamping unit to drive the second clamping unit to move synchronously vertically, realizing single-operation linkage clamping, greatly simplifying the operation steps, ensuring accurate clamping position, avoiding component offset, and the spring-driven method can adapt to slight differences in component size, adapting to clamping multiple specifications of components, and has strong versatility; the overall structure has no complex driving components, is compact in size and light in weight, easy to operate with one hand, adaptable to flexible working scenarios, and effectively solves the problems of cumbersome operation, poor protection, and insufficient adaptability and convenience of traditional clamps.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a linkage clamp structure, including a base plate 1. A first clamping unit 4 that can slide laterally and a second clamping unit 5 that can slide longitudinally are provided on the upper surface of the base plate 1. The movement directions of the first clamping unit 4 and the second clamping unit 5 are perpendicular to each other. A placement groove 6 for placing components is formed on the base plate 1 at the intersection of the movement directions of the first clamping unit 4 and the second clamping unit 5.

[0021] like Figure 1 As shown, the first clamping unit 4 is located on the left side and can slide left and right, while the second clamping unit 5 is located on the right side and can slide back and forth. The placement groove 6 is located at the intersection of the two movement directions, that is, at the right front of the substrate 1. When the first clamping unit 4 moves to the right, the second clamping unit 5 moves forward, and the two work together to clamp the workpiece.

[0022] The first clamping unit 4 includes a rotating wheel 44, and the second clamping unit 5 includes a guide plate 53 extending to one side of the first clamping unit 4 and inclined forward at its outer end. The front side of the guide plate 53 contacts the rotating wheel 44.

[0023] like Figure 2 As shown, the installation position of the rotating wheel 44 is inclined along the axial direction of the first sliding plate 41 to the side away from the placement groove 6, that is, inclined towards the tail of the second clamping unit 5, so that it can contact the guide plate 53 on the second clamping unit 5.

[0024] When the first clamping unit 4 is pulled outward, the rotating wheel 44 moves outward and squeezes the guide plate 53, pushing the second clamping unit 5 to move backward synchronously. The tail of the first clamping unit 4 and the tail of the second clamping unit 5 are respectively provided with elastic elements that drive them to reset and clamp the workpiece in the direction of the placement groove 6.

[0025] When the first clamping unit 4 is in the outermost position and stationary, the rotating wheel 44 is in the outermost position, that is, in contact with the outermost end of the front side of the guide plate 53. Since the outer end of the guide plate 53 is tilted forward, the guide plate 53 is limited by the rotating wheel 44 and is in the rearmost position. At the same time, the second clamping unit 5 is stationary in the rearmost position. The second clamping unit 5 is subjected to the elastic force of the elastic element and has a tendency to move forward. However, since the guide plate 53 is pressed against the rotating wheel 44, the second clamping unit 5 cannot move forward and achieves synchronous stationary position.

[0026] When the first clamping unit 4 moves inward, the rotating wheel 44 also moves inward synchronously, that is, it gradually moves to the innermost position of the guide plate 53. The second clamping unit 5 is always pushed forward by the elastic element. Since the outer end of the guide plate 53 is tilted forward and the front side is in contact with the rotating wheel 44, a position difference will be formed between the outer end and the inner end of the front side of the guide plate 53, that is, a certain movement space will be formed. Therefore, when the rotating wheel 44 moves inward, the second clamping unit 5 will move forward synchronously under the action of the elastic element until the first clamping unit 4 moves inward.

[0027] The rotating wheel 44 can rotate, so that there is rolling friction or sliding + rolling friction between it and the guide plate 53. The friction is small, the service life is better, and the accuracy will not be reduced due to friction.

[0028] Since the tail end of the first clamping unit 4 is also equipped with an elastic element, when there is no external force, it will be subjected to the action of the elastic element, so that the first clamping unit 4 and the second clamping unit 5 are located at the innermost and the frontmost positions respectively. The two cooperate to automatically clamp the workpiece. When it is necessary to release the workpiece, the first clamping unit 4 is pulled outward, which will drive the second clamping unit 5 to move backward synchronously, so that the two clamping units are disengaged from the workpiece, thereby picking up and putting down the workpiece. After the new workpiece is placed in place, the first clamping unit 4 is released. Under the action of the elastic element, the two clamping units move synchronously to return to the state of clamping the workpiece.

[0029] Please refer to Figure 3 Furthermore, in this embodiment, the first clamping unit 4 includes a first sliding plate 41, the head end of the first sliding plate 41 is provided with a first clamp 42, the first sliding plate 41 is provided with an inclined outward extending mounting position 43, and the rotating wheel 44 is rotatably disposed at the mounting position 43.

[0030] The first sliding plate 41 is slidably connected to the base plate 1 via the first slide rail 7. The first sliding plate 41 is also provided with a pull plate 41 for pulling the first sliding plate 41 to move towards the tail end.

[0031] Mounting position 43 is tilted at a certain angle toward the rear end of the entire device, and the side of the first sliding plate 41 is also tilted at a certain angle to avoid interference with the guide plate 43.

[0032] The rotating wheel 44 is mounted at the mounting position 43 via the mounting shaft.

[0033] Please refer to Figure 4 Furthermore, the second clamping unit 5 includes a second sliding plate 51, a second chuck 52 is provided at the front end of the second sliding plate 51, and a positioning groove 54 adapted to the rotating wheel 44 is formed at the connection between the second sliding plate 51 and the guide plate 53.

[0034] In this embodiment, the second sliding plate 51 is slidably connected to the base plate 1 via the second sliding rail 8.

[0035] The positioning groove 51 is an arc-shaped groove. When the first clamping unit 4 is at the innermost end, the second clamping unit 5 is at the front end at the same time. At this time, the rotating wheel 44 is embedded in the positioning groove 54 to achieve a locking effect and avoid the small movement caused by external force from affecting the clamping stability.

[0036] Both the first chuck 42 and the second chuck 52 have elastic protective pads at their heads, which can be made of silicone, to prevent the chucks from making direct rigid contact with the workpiece, thus avoiding damage or deformation to the workpiece.

[0037] Furthermore, a baffle 2 is provided on one side and the rear end of the substrate 1, a first spring 9 is provided between the tail of the first clamping unit 4 and the baffle 2, and a second spring 10 is provided between the tail of the second clamping unit 5 and the baffle 2.

[0038] Both the first spring 9 and the second spring 10 are compression springs, which are always in a compressed state. When no external force is applied, the first clamping unit 4 and the second clamping unit 5 are always in the position of clamping the workpiece under their elastic force.

[0039] The first spring 9 and the second spring 10 can be selected from different models of springs to obtain sufficient elastic force to achieve clamping. Since the workpiece being clamped is a small electronic component, the spring is fully capable of meeting the force required to clamp the workpiece.

[0040] A handle 3 is provided at the rear end of the base plate 1. It is used to hold the entire device for inspecting and repairing workpieces.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
