Description

Technical Field

[0001] This utility model relates to the field of welding tooling manufacturing technology, specifically a horizontal fixed 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 horizontal friction welding fixture that enables omnidirectional fixation of workpieces in three-dimensional space, significantly improving production efficiency and welding quality. It is particularly 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:

[0009] A friction welding horizontal fixing fixture includes a base plate. A positioning block one is provided on one side of the upper part of the base plate, and the positioning block one forms a right-angle positioning reference in the X direction with the base plate. An X-direction pressing assembly is provided on the other side of the upper part of the base plate opposite to the positioning block one. A positioning block two is provided on the front or rear side of the upper part of the base plate, and the positioning block two forms a right-angle positioning reference in the Y direction with the base plate.

[0010] Furthermore, a reference seat one is provided on one side of the upper part of the base plate, which is set on the same side as the positioning block; a reference seat two is provided on the other side of the upper part of the base plate opposite to the reference seat one; a number of lifting cylinders are also provided on the upper part of the base plate, which are evenly distributed along the working surface of the base plate, and together form a support structure that can adjust the horizontal placement height of the workpiece.

[0011] Furthermore, the X-direction pressing assembly includes a drive cylinder fixed to the upper part of the base plate. The output end of the drive cylinder is rotatably connected to a transmission block. One side of the transmission block is provided with an inclined connecting part, and the inclined connecting part is provided with a push block that cooperates with it. The transmission block is driven by the drive cylinder, which drives the push block to make linear motion, aligning multiple workpieces simultaneously to the right-angle positioning reference in the X direction and pressing them together.

[0012] Furthermore, the Y-direction pressing assembly includes a second driving cylinder fixed to the upper part of the base plate. The output end of the second driving cylinder is rotatably connected to a second transmission block. One side of the second transmission block is provided with an inclined connecting part, and the inclined connecting part is provided with a second push block that cooperates with it. The second transmission block is driven by the second driving cylinder, which drives the second push block to make linear motion, so as to simultaneously align multiple workpieces to the right-angle positioning reference in the Y direction and perform pressing.

[0013] Furthermore, the Z-direction pressing assembly includes a third driving cylinder, the output end of which is connected to a pressing block. The pressing block has symmetrical linkage blocks on both sides. One end of the linkage block is rotatably connected to the pressing block, and the other end is rotatably connected to a connecting seat fixed on the third driving cylinder. The pressing block is driven by the third driving cylinder to swing around the rotation axis, and its pressing surface is used to press and fix the workpiece.

[0014] Compared with existing technologies, this invention offers the following advantages: It provides a horizontal friction welding fixture, including a base plate. A positioning block 1 is positioned on one side of the upper part of the base plate, forming a right-angle positioning reference in the X direction with the base plate. An X-direction pressing assembly is positioned on the opposite side of the upper part of the base plate. A second positioning block 2 is positioned on the front or rear side of the upper part of the base plate, forming a right-angle positioning reference in the Y direction with the base plate. A Y-direction pressing assembly is positioned on the opposite side of the base plate. A Z-direction pressing assembly is also positioned on the upper part of the base plate. By using the positioning block 1 to form an X-direction reference with the base plate and the positioning block 2 to form a Y-direction reference, rapid and accurate positioning of the workpiece in the horizontal plane is achieved, avoiding the cumbersome operation of multiple adjustments required by traditional fixtures. The X / Y direction pressing assembly and the Z-direction pressing assembly work together to achieve omnidirectional fixation of the workpiece in three-dimensional space, significantly improving production efficiency and welding quality, and is particularly suitable for friction welding production scenarios involving multiple workpieces and high precision.

Reference seats 7 and 8 provide auxiliary positioning references, and together with the evenly distributed lifting cylinders 9, they form an adjustable support structure to adapt to the horizontal calibration requirements of workpieces of different heights and improve the versatility of the fixture.

[0022] The X-direction pressing assembly 3 includes a drive cylinder 30 fixed to the upper part of the base plate 1. A transmission block 31 is rotatably connected to the output end of the drive cylinder 30. One side of the transmission block 31 has a sloping connecting portion, and a push block 32 cooperates with this sloping connecting portion. The transmission block 31 is driven by the drive cylinder 30, causing the push block 32 to move linearly, simultaneously aligning multiple workpieces to the X-direction right-angle positioning reference and performing pressing. The drive cylinder 30 pushes the push block 32 through the sloping connecting portion of the transmission block 31, converting the cylinder's rotational motion into a linear pressing action, achieving synchronous alignment and pressing of multiple workpieces, preventing loosening during welding, and improving welding quality.

[0023] The Y-direction pressing assembly 5 includes a second drive cylinder 50 fixed to the upper part of the base plate 1. A second transmission block 51 is rotatably connected to the output end of the second drive cylinder 50. One side of the second transmission block 51 has a sloping connecting portion, and this sloping connecting portion has a corresponding push block 52. The second transmission block 51 is driven by the second drive cylinder 50, causing the push block 52 to move linearly, simultaneously aligning multiple workpieces to the Y-direction right-angle positioning reference and performing pressing. The second drive cylinder 50 pushes the push block 52 through the sloping connecting portion of the second transmission block 51, converting the cylinder's rotational motion into a linear pressing action, achieving synchronous alignment and pressing of multiple workpieces, preventing loosening during welding, and improving welding quality.

[0024] Z-direction pressing assembly 6 includes a drive cylinder 3 60, the output end of which is connected to a pressing block 61. Symmetrical linkage blocks 62 are provided on both sides of the pressing block 61. One end of each linkage block 62 is rotatably connected to the pressing block 61, and the other end is rotatably connected to a connecting seat 63 fixed on the drive cylinder 3 60. Driven by the drive cylinder 3 60, the pressing block 61 can swing around its rotation axis. Its pressing surface presses and fixes the workpiece, ensuring that the workpiece is pressed in the Z-direction, preventing loosening during welding, and improving welding quality.

[0025] Working Principle: Workpiece 10, workpiece 21, and workpiece 312 are pre-assembled together. The pre-assembled whole workpiece is placed above the base plate 1. Workpiece 10 is placed on the upper part of the reference seat 17, workpiece 312 is placed on the upper part of the reference seat 28, and workpiece 21 is placed on the upper part of the support structure composed of multiple lifting cylinders 9. Initial positioning is achieved through right-angle positioning references in the X and Y directions. Drive cylinder 130 pushes push block 132 to press the workpieces to the right-angle positioning reference in the X direction, ensuring that the welding surfaces are collinear and preventing welding vibration displacement. Drive cylinder 250 pushes push block 252 to press the workpieces to the right-angle positioning reference in the Y direction, ensuring that the welding surfaces are collinear and preventing welding vibration displacement. The pressure block 61, driven by drive cylinder 360, can swing around the rotation axis, and its pressing surface presses and fixes the workpieces to prevent welding vibration displacement. Under the three-dimensional pressing action, the workpieces remain absolutely rigid and fixed, and the friction welding equipment can perform stable welding, 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, enabling continuous operation.
