Description

Technical Field

[0001] This utility model relates to the field of aluminum processing, and in particular to a precision positioning device for aluminum welding. Background Technology

[0002] Aluminum welding requires extremely high positioning accuracy. Traditional clamps often directly lock aluminum profiles with bolts, which can easily cause indentation and deformation of thin-walled parts and lack angle adjustment function. Existing equipment is difficult to achieve precise positioning of multiple degrees of freedom at the same time. Especially in the case of bevel welding and other work that requires tilting angle, the operation is cumbersome. Manual clamping devices cannot guarantee repeatability and positioning accuracy, which affects the quality of batch welding. At the same time, ordinary rotating mechanisms lack self-locking stability and the angle is easy to deviate in the vibration environment.

[0003] Therefore, in order to address the above problems, a precision positioning device for aluminum welding is now being developed. Utility Model Content

[0004] To overcome the shortcomings of existing devices, such as difficulty in achieving precise positioning of multiple degrees of freedom simultaneously, cumbersome operation in conditions requiring tilt angles such as bevel welding, inability of manual clamping devices to guarantee repeatability of positioning accuracy affecting batch welding quality, lack of self-locking stability of ordinary rotating mechanisms, and easy angle deviation under vibration environment, this utility model provides a precise positioning device for aluminum welding.

[0005] The technical implementation scheme of this utility model is as follows: a precision positioning device for aluminum welding includes a mounting plate. A first placement platform is provided on the upper left side of the mounting plate. An adjusting rod is threadedly connected to the front side of the first placement platform. A first clamping plate is slidably connected to the upper side of the first placement platform. The first clamping plate is rotatably connected to the adjusting rod. Two symmetrical support frames are provided on the upper right side of the mounting plate. Each support frame has an arc-shaped groove. A second placement platform is slidably connected between the arc-shaped grooves. An adjusting component is also threadedly connected to the second placement platform. A second clamping plate is slidably connected to the second placement platform. The second clamping plate is rotatably connected to the adjusting component. A rotating mechanism is provided at the rear of the mounting plate. The rotating mechanism is used to adjust the angle of the second placement platform.

[0006] Furthermore, the rotating mechanism includes a drive assembly, which is mounted on the upper rear side of the mounting plate. The drive assembly includes a mounting bracket and a drive motor. Both the output shaft of the drive motor and the rear side of the second placement platform are connected to a driven gear, and the two driven gears mesh with each other.

[0007] Furthermore, it also includes a clamping mechanism, which includes a mounting component. The mounting component is provided on the second placement platform. A pull rod is slidably connected to the mounting component, and a clamping plate is connected to the pull rod. The clamping plate is used to clamp and fix the aluminum material.

[0008] Furthermore, both the first and second clamping plates have anti-slip textures on their inner sides.

[0009] Furthermore, each of the adjusting components is equipped with an assist handle.

[0010] Furthermore, four springs are provided between the clamping plate and the mounting component.

[0011] By adopting the above technical solution, compared with the prior art, this utility model has the following advantages:

[0012] This invention uses an arc-shaped groove guide rail and a drive assembly to drive the gears to achieve stepless and precise adjustment of the placement table tilt angle, meeting the needs of complex bevel welding. At the same time, the independently controlled threaded clamping mechanism provides bidirectional horizontal fine adjustment function to ensure weld alignment accuracy. Overall, it significantly improves the stability of welding quality, reduces rework rate and increases production efficiency. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] A precision positioning device for aluminum welding, such as Figures 1-5 As shown, the device includes a mounting plate 1. A first placement platform 2 is provided on the upper left side of the mounting plate 1. An adjusting rod 3 is threadedly connected to the front of the first placement platform 2. A first clamping plate 4 is slidably connected to the upper side of the first placement platform 2. The first clamping plate 4 is rotatably connected to the adjusting rod 3. Two symmetrical support frames 7 are provided on the upper right side of the mounting plate 1. Each support frame 7 has an arc-shaped groove. A second placement platform 6 is slidably connected between the arc-shaped grooves. An adjusting component is also threadedly connected to the second placement platform 6. A second clamping plate 5 is slidably connected to the second placement platform 6. The inner sides of the first clamping plate 4 and the second clamping plate 5 are provided with anti-slip textures. The second clamping plate 5 is rotatably connected to the adjusting component. The adjusting component is provided with an assist handle. The rear of the mounting plate 1 is provided with a rotating mechanism 8. The rotating mechanism 8 is used to adjust the angle of the second placement platform 6. The rotating mechanism 8 includes a drive assembly 81. The drive assembly 81 is installed on the upper rear side of the mounting plate 1. The drive assembly 81 includes a mounting frame and a drive motor. The output shaft of the drive motor and the rear side of the second placement platform 6 are both connected with driven gears 82. The two driven gears 82 mesh with each other.

[0021] It also includes a pressing mechanism 9, which includes a mounting component 91. The mounting component 91 is provided on the second placement platform 6. A pull rod 92 is slidably connected to the mounting component 91. A pressing plate 93 is connected to the pull rod 92. The pressing plate 93 is used to press and fix the aluminum material. Four springs 94 are provided between the pressing plate 93 and the mounting component 91.

[0022] It should be noted that during operation, the two sections of aluminum material to be welded are first placed on the left first placement platform 2 and the right second placement platform 6 respectively, with the left fixed end positioned. The adjusting rod 3 on the front of the first placement platform 2 is rotated, and its threaded transmission pushes the first clamping plate 4, which is rotatably connected to it, to move horizontally along the platform slide rail. The inner anti-slip texture engages with the end face of the aluminum material, achieving precise horizontal clamping and positioning. Then, the assist handle on the adjusting component of the second placement platform 6 is rotated simultaneously, driving the second clamping plate 5 to slide and clamp the other section of aluminum material. Next, the drive motor of the rotating mechanism 8 is started, and its output shaft, driven by the gear 82, precisely meshes with the driven gear 82 on the rear side of the second placement platform 6. The motor rotates forward and backward through the inter-tooth force, driving the second placement platform 6 to slide along the arc-shaped groove on the support frame 7, so that the right side... The aluminum material can be tilted from 0 to 90° around the axis. The mechanical limit of the arc groove ensures smooth angle changes without deviation. If the aluminum material is thin and prone to vibration, the clamping plate 93 can be controlled by the pull rod 92 to apply a flexible constant pressure to the surface of the aluminum material. The spring 94 buffers the force, avoiding material indentation and eliminating welding thermal deformation displacement. The anti-slip texture of the clamping plates on both sides ensures that the aluminum material does not slide circumferentially when under welding force. By finely adjusting the left adjustment rod 3 and the right adjustment piece, the weld gap and misalignment can be precisely calibrated. After the drive motor has adjusted the angle, it self-locks and holds the position. The whole process realizes independent control of the aluminum material at both ends. The left side provides an axial reference, and the right side completes the spatial angle orientation. Combined with the deformation protection of the clamping mechanism 9, it provides a free and stable clamping environment for high-precision welding.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
