Description

Technical Field

[0001] This utility model relates to the field of box body processing fixtures, specifically a thin-walled box body processing fixture. Background Technology

[0002] During the machining of thin-walled box-shaped workpieces, these workpieces are particularly susceptible to vibration and deformation due to their thin walls, especially under welding or other high-temperature and high-pressure processing conditions. To ensure machining quality and avoid machining errors caused by uneven stress, specially designed machining fixtures for thin-walled box-shaped workpieces are traditionally used. The main function of this fixture is to ensure the correct position and orientation of the workpiece during machining by restricting its six degrees of freedom (i.e., translation and rotation along three coordinate axes), thus maintaining the workpiece's stable positioning throughout the machining process.

[0003] However, traditional fixtures for machining thin-walled boxes have significant limitations. Since thin-walled boxes are typically square, the fixture needs to fit snugly against all four sides of the box for effective clamping and fixation. This results in rigid designs and fixed dimensions for existing fixtures, making it difficult to adapt to thin-walled boxes of different sizes. If the dimensions of the box change slightly, existing fixtures cannot effectively clamp it, greatly limiting their application range and reducing their flexibility and practicality. Therefore, a new fixture for machining thin-walled boxes is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a thin-walled box-type machining fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thin-walled box processing fixture, including an inner fixture and an outer fixture respectively disposed on the inner and outer surfaces of the thin box. The outer fixture includes multiple sets of right-angle clamps and multiple sets of connecting components. Each set of adjacent right-angle clamps is connected by a connecting component. The connecting component includes an elastic element connecting two sets of adjacent right-angle clamps, and a limiting structure restricting the movement direction of the right-angle clamps is also provided between two sets of adjacent right-angle clamps.

[0006] As a further embodiment of this utility model: the limiting structure includes a sleeve plate installed on the end face of the right-angle clamping plate, a connecting rod installed inside the sleeve plate, one end of the connecting rod passing through the interior of the sleeve plate and connecting to the end face of the adjacent right-angle clamping plate, and a limiting head installed at the end of the connecting rod located inside the sleeve plate to prevent the connecting rod from detaching from the interior of the sleeve plate.

[0007] As a further embodiment of this utility model: the inner clamp includes a first inner clamping plate and a second inner clamping plate, and a rotating component connecting the first inner clamping plate and the second inner clamping plate, wherein an extension component is installed on the end face of the first inner clamping plate and the second inner clamping plate away from the rotating component.

[0008] As a further embodiment of this utility model: the rotating component includes two connecting plates respectively fixed on both sides of the first inner clamping plate, and each of the two connecting plates is equipped with a rotating shaft connected to the second inner clamping plate, for realizing rotation between the first inner clamping plate and the second inner clamping plate.

[0009] As a further embodiment of this utility model: the extension component includes a groove formed on the first inner clamping plate, the groove being located on the surface of the first inner clamping plate that is in contact with the thin box, the surface of the first inner clamping plate having a strip groove communicating with the groove, and symmetrical sliding grooves formed in the groove, with V-shaped positioning grooves formed in both sliding grooves.

[0010] As a further embodiment of this utility model: the extension component also includes a movable plate movably installed in the groove, a push rod located in the strip groove is installed on the surface of the movable plate, and sliders located in the slide groove are installed on both sides of the movable plate.

[0011] As a further embodiment of this utility model: a V-shaped positioning block is installed on the end face of the slider near the V-shaped positioning groove, and the end of the V-shaped positioning block is connected to a spring inside the slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This application comprises four sets of right-angle clamping plates and connecting components to form an adjustable-size square external clamp. This design not only increases the adaptability of the external clamp to the outer walls of thin-walled boxes of various sizes, but also ensures the stability of the clamping. At the same time, the combination of the first and second inner clamping plates provides effective support for the inner walls of the thin-walled boxes, preventing deformation during welding. Furthermore, under the action of elastic elements and extension components, the lengths of the first and second inner clamping plates are adjusted by the extension components to fit the inner walls of thin-walled boxes of different sizes, further enhancing the effect of internal support. It can also significantly improve the flexibility of the clamping system, enabling it to quickly adapt to thin-walled boxes of different sizes and shapes. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 In this embodiment of the present invention, a thin-walled box processing fixture includes an inner fixture 1 and an outer fixture 2 respectively disposed on the inner and outer surfaces of the thin box. The outer fixture 2 includes multiple sets of right-angle clamps 21 and multiple sets of connecting components 22. In this embodiment, there are four sets of right-angle clamps 21 and four sets of connecting components 22. Each set of adjacent right-angle clamps 21 is connected by connecting components 22. The design of the connecting components 22 allows the spacing between each set of right-angle clamps 21 to be adjusted within a certain range, thereby achieving the effect of adapting to thin boxes of different sizes. The connecting components 22 include elastic elements 22-1 that connect two sets of adjacent right-angle clamps 21, and a limiting structure 22 that restricts the movement direction of the right-angle clamps 21 is also provided between the two sets of adjacent right-angle clamps 21. -2, wherein the elastic element 22-1 is a tension spring, or it can be a tension rope or other elastic element with tension. In addition, in order to ensure the accuracy and stability of the right angle clamp 21 during position adjustment, a limiting structure 22-2 is specially designed. The function of the limiting structure 22-2 is to constrain the movement path of the right angle clamp 21, so that it can only be adjusted in a predetermined direction. This design feature ensures that even when multiple sets of right angle clamps 21 work together, the stability and consistency of the overall structure can be maintained. Through the tension provided by the elastic element 22-1 and the control of the movement direction by the limiting structure 22-2, the right angle clamp 21 can be flexibly adjusted in position when needed and can maintain a stable state after adjustment.

[0022] Please see Figure 2 In one embodiment, preferably, the limiting structure 22-2 includes a sleeve 22-21 installed on the end face of the right-angle clamp 21. A connecting rod 22-22 is movably installed inside the sleeve 22-21. One end of the connecting rod 22-22 extends out of the sleeve 22-21 and connects to the end face of the adjacent right-angle clamp 21. A limiting head 22-23 is installed at the end of the connecting rod 22-22 inside the sleeve 22-21 to limit the connecting rod 22-22 from detaching from the inside of the sleeve 22-21. It can also limit the maximum range of motion between the two sleeves 22-21, and prevent the elastic element 22-1 from failing to effectively rebound to the initial state due to excessive stretching distance between the two sleeves 22-21.

[0023] Please see Figure 3 In one embodiment, preferably, the inner clamp 1 includes a first inner clamping plate 11 and a second inner clamping plate 12, and a rotating member 13 connecting the first inner clamping plate 11 and the second inner clamping plate 12. The end faces of the first inner clamping plate 11 and the second inner clamping plate 12 away from the rotating member 13 are each equipped with an extension component 14. The rotating member 13 can adjust the tilt angle between the first inner clamping plate 11 and the second inner clamping plate 12, so as to adapt to the inner wall of the thin box at different angles. Even if the included angle of the inner wall of the thin box is not a right angle, it can ensure that the first inner clamping plate 11 and the second inner clamping plate 12 are in contact with the inner wall of the thin box, thereby clamping and fixing the thin-walled box, providing stability for the thin box during processing, and effectively preventing the thin box from deforming during processing.

[0024] Please see Figure 3 In one embodiment, preferably, the rotating component 13 includes two connecting plates 13-1 respectively fixed on both sides of the first inner clamping plate 11. Each of the two connecting plates 13-1 is equipped with a rotating shaft 13-2 connected to the second inner clamping plate 12, which is used to realize the rotation between the first inner clamping plate 11 and the second inner clamping plate 12. The connection plates 13-1 are provided so that a certain gap is maintained at the connection between the first inner clamping plate 11 and the second inner clamping plate 12, ensuring that the first inner clamping plate 11 and the second inner clamping plate 12 will not be jammed by the other when they move relative to each other.

[0025] Please see Figure 3-5In one embodiment, preferably, the extension component 14 includes a groove 14-1 formed on the first inner clamping plate 11, the groove 14-1 being located on the surface of the first inner clamping plate 11 that adheres to the thin box, a strip groove 14-2 communicating with the groove 14-1 being formed on the surface of the first inner clamping plate 11, symmetrical sliding grooves 14-3 being formed in the groove 14-1, and V-shaped positioning grooves 14-4 being formed in both sliding grooves 14-3, a movable plate 14-5 being movably installed in the groove 14-1, a push rod 14-6 located in the strip groove 14-2 being installed on the surface of the movable plate 14-5, and sliders 14-7 located in the sliding grooves 14-3 being installed on both sides of the movable plate 14-5, when the lengths of the first inner clamping plate 11 and the second inner clamping plate 12 cannot match the dimensions of the inner wall of the thin box, the extension component can be used. The design of the slide 14-3 and the V-shaped positioning groove 14-4 increases the effective length of the first inner clamping plate 11 and the second inner clamping plate 12, ensuring that they can fit and stably clamp the inner wall of the box. At the same time, the design of the slide 14-3 and the V-shaped positioning groove 14-4 can also effectively prevent the moving plate 14-5 from disengaging from the groove 14-1. In addition, in order to fix the adjusted position, a V-shaped positioning block 14-8 is installed on the end face of the slider 14-7 near the V-shaped positioning groove 14-4. The end of the V-shaped positioning block 14-8 is connected to the spring 14-9 in the slider 14-7. The function of the spring 14-9 is to push the V-shaped positioning block 14-8 towards the V-shaped positioning groove 14-4, so that the two fit tightly together. This ensures that once the user adjusts the position of the moving plate 14-5, it can be firmly locked in the required position, thereby effectively supporting the clamping function of the inner clamping plate on the inner wall of the box.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
