Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, specifically a vertical fixing fixture for friction welding. Background Technology

[0002] Friction welding, as a highly efficient and environmentally friendly solid-state joining technology, has been widely used in aerospace, automotive manufacturing, and other fields. With the improvement of industrial automation, welding processes have placed higher demands on the positioning accuracy, rigid fixation, and simultaneous processing capability of workpiece clamping fixtures.

[0003] Traditional friction welding fixtures mostly adopt a split positioning structure, which has the following technical defects:

[0004] The workpiece clamping requires repeated adjustments to the X / Y / Z axis positions, which is cumbersome and the positioning efficiency is difficult to meet the needs of continuous production.

[0005] In multi-workpiece welding scenarios, traditional fixtures struggle to achieve synchronous alignment and pressing of the workpieces, and the cumulative error between workpieces directly affects the collinearity of the welding surfaces.

[0006] In summary, existing technologies have not yet effectively solved the challenges of rapid positioning and dynamic rigid fixation in high-precision, multi-workpiece welding scenarios. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a vertical friction welding fixture. Through the synergistic effect of right-angle positioning reference, multi-dimensional pressing components, and mechanical locking, it achieves rapid and precise clamping and stable welding of workpieces, significantly improving production efficiency and welding quality. It is especially suitable for friction welding production scenarios involving multiple workpieces and high precision.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0023] 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.

[0024] Please see Figures 1 to 6This utility model provides a technical solution: a vertical friction welding fixture, including a base plate 1 and a vertical plate 2 mounted on the base plate 1. A positioning block 3 is provided on one side of the main surface of the vertical plate 2, forming a right-angle positioning reference with the vertical plate 2. An X-direction pressing component 4 is provided on the other side of the main surface of the vertical plate 2. Y-direction pressing components 5 are respectively provided on both sides of the main surface of the vertical plate 2, and a locking component 6 and a Z-direction pressing component 7 are provided on the upper part of the Y-direction pressing components 5. The right-angle positioning reference formed by the positioning block 3 and the vertical plate 2 enables rapid and accurate positioning of the workpiece. The collaborative design of the X-direction pressing component 4 and the Y-direction pressing component 5 enables multi-dimensional pressing of the workpiece in the horizontal and vertical directions, ensuring stability during the welding process. The design of the locking component 6 and the Z-direction pressing component 7 further prevents vibration or displacement during the welding process. This friction welding vertical fixture achieves rapid and precise workpiece clamping and stable welding through the synergistic effect of right-angle positioning reference, multi-dimensional pressing components and mechanical locking, significantly improving production efficiency and welding quality. It is especially suitable for friction welding production scenarios with multiple workpieces and high precision.

[0025] The X-direction pressing assembly 4 includes a drive cylinder 40 fixed to the back of the upright plate 2. The output end of the drive cylinder 40 passes through the upright plate 2 and is rotatably connected to a transmission block 41. One side of the transmission block 41 has an inclined connecting portion, and this inclined connecting portion has a push block 42 that cooperates with it. The transmission block 41 is driven by the drive cylinder 40, which drives the push block 42 to move linearly, aligning multiple workpieces simultaneously to a right-angle positioning reference and pressing them together. The drive cylinder 40 pushes the push block 42 through the inclined connecting portion of the transmission block 41, converting the rotational motion of the cylinder into a linear pressing action, realizing the synchronous alignment and pressing of multiple workpieces, preventing loosening during the welding process, and improving the welding quality.

[0026] The Y-direction pressing assembly 5 includes a fixed base 50 fixed to the main surface of the vertical plate 2. A middle block 51 and a swing block 52 are sequentially arranged on the upper part of the fixed base 50. A rotating shaft 53 is internally connected to the fixed base 50 and the middle block 51. One end of the swing block 52 is rotatably connected to the rotating shaft 53, and the other end has a connecting block 54 perpendicularly arranged to it. The side of the swing block 52 has a horizontal surface. The swing block 52 rotates along the rotating shaft 53 and aligns multiple workpieces simultaneously to the main surface of the vertical plate 2 through its horizontal side surface. The design of the swing block 52 rotating via the rotating shaft 53 achieves adaptive alignment of the workpieces to the main surface of the vertical plate 2, accommodating workpieces of different sizes. The modular structure of the fixed base 50, the middle block 51, and the swing block 52 facilitates maintenance and replacement, improving the durability of the fixture.

[0027] The locking assembly 6 includes a second drive cylinder 60 fixed to the upper part of the connecting block 54. The output end of the second drive cylinder 60 is connected to a locking tongue 61 that passes through the connecting block 54. When driven by the second drive cylinder 60, the locking tongue 61 extends downward and abuts against the back of the upright plate 2, thereby mechanically locking the swing block 52. The mechanical locking design between the locking tongue 61 and the back of the upright plate 2 provides reliable rigid fixation, prevents loosening during the welding process, and improves welding quality.

[0028] The Z-direction pressing assembly 7 includes a drive cylinder 3 70 fixed to the upper part of the connecting block 54. A pressing block 71 is connected to the output end of the drive cylinder 3 70. At least one pressing part 72 is provided at the lower part of the pressing block 71. The bottom surface of the pressing part 72 is horizontal. When the pressing block 71 is driven by the drive cylinder 3 70, it moves downwards, aligning the workpiece to the main surface of the base plate 1 and performing pressing through the horizontal surface of its pressing part. By designing the pressing part 72, the workpiece is pressed in the Z-direction while avoiding the connecting block 54, preventing loosening during welding and improving welding quality. To better press the workpiece in the Z-direction, pressing parts 72 can be provided at both ends of the lower part of the pressing block 71 according to actual production needs to further improve pressing stability.

[0029] The front side of the main surface of the base plate 1 is provided with a support body 8 for supporting the fixed seat 50 and a support body 9 for supporting the swing block 52. The rear side of the main surface of the base plate 1 is provided with a support body 3 10 for fixing the upright plate 2. The design of the support body 8, support body 9 and support body 3 10 enhances the overall rigidity of the fixture.

[0030] Working Principle: Workpieces 11, 12, and 13 are pre-assembled together. The pre-assembled whole workpiece is placed on the base plate 1, and initial positioning is achieved through the right-angle reference formed by the upright plate 2 and the positioning block 3. Drive cylinder 40 pushes the push block 42 to press the workpiece against the right-angle reference, ensuring that the welding surfaces are collinear. The swing block 52 of the Y-direction pressing assembly 5 rotates through the rotating shaft 53, so that the workpiece is in contact with the main surface of the upright plate 2, completing the Y-direction alignment. Drive cylinder 60 controls the locking tongue 61 to press against the back of the upright plate 2, locking the position of the swing block 52 to prevent welding vibration displacement. Drive cylinder 70 drives the pressure block 71 to press down, so that the bottom of the workpiece is tightly against the base plate 1, eliminating vertical gaps. Under the combined action of three-dimensional pressing and mechanical locking, the workpiece remains absolutely rigid and fixed, and the friction welding equipment can perform welding stably, avoiding weld defects caused by vibration. After welding is completed, each cylinder resets in sequence, the pressing assembly is released from constraint, and the workpiece can be quickly removed, realizing continuous operation.
