Description

Technical Field

[0001] This invention belongs to the technical field of aluminum welding tools, and in particular relates to a novel welding fixture for aluminum parts in engine room. Background Technology

[0002] In the manufacturing of the cabin, aluminum components are an important part. During the processing of aluminum components, they need to be welded together to form specific parts for cabin assembly. Welding, also known as mechanical tailoring, is responsible for welding stamped workpieces together and is widely used in the manufacturing industry. The degree of automation and flexibility of welding determines the development prospects and future of welding. In the welding process, welding fixtures are used to clamp and fix the workpieces for welding.

[0003] Existing welding fixtures typically use clamping mechanisms to directly fix workpieces during installation. However, this process can cause excessive pressure on the workpiece, leading to deformation and damage, which affects the stability of welding. Furthermore, the fixtures lack stability when clamping workpieces, which is not conducive to welding. To address these issues, we propose a novel welding fixture for aluminum cabin parts. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a novel welding fixture for aluminum parts in the cabin, which avoids the problems of existing welding fixtures causing excessive compression on the workpiece during installation and fixing, which can lead to deformation and damage of the workpiece, affecting the stable welding of the workpiece, and the lack of stability when clamping the workpiece, which is not conducive to the subsequent welding work of the workpiece.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a novel welding fixture for aluminum parts in a cabin, comprising a base plate, two support plates fixedly connected to the upper surface of the base plate, two housings fixedly connected to the upper surface of the base plate, and a first cylinder disposed within the housing. The output end of the first cylinder is hinged to a clamping mechanism via a pin. Two connecting plates are disposed on the outer wall of the bottom end of the clamping mechanism, and the two ends of the connecting plates are respectively connected to the outer wall of the clamping mechanism and the outer wall of the housing via pins. Three tubular pads are clamped to the upper surface of each of the two support plates. The bottom ends of the three tubular pads are connected to the same connecting pipe. A cavity is disposed outside the connecting pipe. A piston block is disposed within the cavity. A pull rope is fixedly connected to one end of the piston block, and the other end of the pull rope is connected to the clamping mechanism. A pad is disposed within each tubular pad. Two second springs are fixedly connected to the lower surface of the pad. A magnetic disk is fixedly connected to the inner wall of the tubular pad. The bottom ends of the second springs are fixedly connected to the upper surface of the magnetic disk.

[0006] As a preferred embodiment of the present invention, the outer wall of the pad is provided with a rubber layer, and the upper surface of the pad is provided with anti-slip texture.

[0007] In a preferred embodiment of the present invention, the pad is made of magnetic material, and the magnetic pole direction of the pad is the same as that of the magnetic disk.

[0008] As a preferred embodiment of the present invention, the upper surface of the magnetic disk is provided with through holes, and the through holes have a mesh structure.

[0009] As a preferred embodiment of the present invention, one end of the piston block is fixedly connected to a first spring, and the other end of the first spring is fixedly connected to the back side of the inner wall of the cavity.

[0010] As a preferred embodiment of the present invention, an inner support plate is provided on one side of the support plate, and the left and right sides of the inner support plate are respectively fixedly connected to the opposite surfaces of the two inner support plates. A plurality of fixing strips are provided on the lower surface of the base plate, and the fixing strips are made of rubber.

[0011] As a preferred embodiment of the present invention, a fixing frame is fixedly connected to the upper surface of the base plate, a second cylinder is installed on the upper surface of the fixing frame, and a pressure plate is fixedly connected to the output end of the cylinder through a damper.

[0012] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0013] 1. This device supports the workpiece using a support plate. The cooperation between the first cylinder and the housing allows the extension and retraction of the first cylinder to rotate one end of the clamping mechanism, causing both clamping mechanisms to grip the workpiece. When the clamping mechanism is open, a pull rope pulls the piston block outward, creating negative pressure in both the cavity and the tubular pad. This causes the pad to contract into the tubular pad, allowing the workpiece to be placed stably on the support plate. When the clamping mechanism rotates to pressurize and fix the workpiece, the piston block returns to its original position, bringing the tubular pad to normal pressure. This allows the pad to extend from the tubular pad via a second spring, providing elastic protection for the workpiece. This design ensures stable workpiece fixation and automatically provides elastic shock absorption during clamping, facilitating welding operations.

[0014] 2. This device, through the cooperation of the fixed frame and the cylinder, can drive the pressure block to rise and fall. When the workpiece is pressed and fixed by the two clamping mechanisms, the pressure block is driven to fall and squeeze and fix the upper part of the workpiece. With the cooperation of the clamping mechanism, the workpiece can be fixed in multiple directions to prevent it from loosening and deforming under force. Moreover, through the action of the damper, it can prevent the pressure block from over-compressing the workpiece, thus providing good stability for the workpiece. Attached Figure Description

However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0023] Example

[0024] like Figures 1-6The above describes a novel welding fixture for aluminum components in an engine compartment. It includes a base plate 1, with two support plates 5 fixedly connected to the upper surface of the base plate 1. Two housings 3 are also fixedly connected to the upper surface of the base plate 1, and a first cylinder 2 is housed within each housing 3. The output end of the first cylinder 2 is hinged to a clamping mechanism 6 via a pin. Two connecting plates 7 are provided on the outer wall of the bottom end of the clamping mechanism 6, and both ends of the connecting plates 7 are connected to the outer wall of the clamping mechanism 6 and the outer wall of the housing 3 respectively via pins. Three tubular pads are clamped to the upper surfaces of both support plates 5. 8. The bottom ends of the three tubular pads 8 are connected to the same connecting pipe 10. A cavity 11 is provided outside the connecting pipe 10. A piston block 13 is provided inside the cavity 11. A pull rope 4 is fixedly connected to one end of the piston block 13, and the other end of the pull rope 4 is connected to the clamping mechanism 6. A pad 9 is provided inside the tubular pad 8. Two second springs 14 are fixedly connected to the lower surface of the pad 9. A magnetic disk 15 is fixedly connected to the inner wall of the tubular pad 8. The bottom end of the second spring 14 is fixedly connected to the upper surface of the magnetic disk 15.

[0025] In other embodiments, the outer wall of the pad 9 is provided with a rubber layer, and the upper surface of the pad 9 is provided with anti-slip texture;

[0026] This design allows the outer wall of the pad 9 to fit tightly against the tubular pad 8. When the tubular pad 8 is under negative pressure, the pad 9 can be forcefully contained within the tubular pad 8, preventing obstruction of workpiece placement. Furthermore, when the pad 9 extends to provide elastic shock absorption for the workpiece, the anti-slip texture increases the friction between it and the workpiece, thus providing an anti-slip effect.

[0027] In other embodiments, the pad 9 is made of magnetic material, and the magnetic pole direction of the pad 9 is the same as the magnetic pole direction of the magnetic disk 15.

[0028] With this design, when the pad 9 is subjected to workpiece pressure, it can provide shock absorption protection for the workpiece through the second spring 14, and through the magnetic force of repulsion between the same level, it can further provide shock absorption and buffering function.

[0029] In other embodiments, the upper surface of the magnetic disk 15 is provided with through holes 16, and the through holes 16 have a mesh structure;

[0030] This design ensures ventilation inside the tubular pad 8, allowing for air extraction from its inner wall to maintain a negative pressure state. Meanwhile, the mesh structure of the through-hole 16 contributes to its structural stability.

[0031] In other embodiments, one end of the piston block 13 is fixedly connected to a first spring 12, and the other end of the first spring 12 is fixedly connected to the back side of the inner wall of the cavity 11.

[0032] With this design, when the clamping mechanism 6 rotates to pressurize and fix the workpiece, the piston block 13 can be automatically reset by the first spring 12.

[0033] In other embodiments, an inner support plate 17 is provided on one side of the support plate 5, and the left and right sides of the inner support plate 17 are fixedly connected to the opposite surfaces of the two inner support plates 17 respectively. A plurality of fixing strips 22 are provided on the lower surface of the base plate 1, and the fixing strips 22 are made of rubber.

[0034] This design allows the support plate 5 to support the workpiece from below, and the bottom of the base plate 1 has a good anti-slip effect during installation, making the welding fixture structurally stable during installation.

[0035] In other embodiments, a fixing frame 18 is fixedly connected to the upper surface of the base plate 1, and a second cylinder 19 is installed on the upper surface of the fixing frame 18. The output end of the cylinder is fixedly connected to a pressure plate through a damper 20.

[0036] This design allows the damper 20 to prevent the pressure block 21 from excessively squeezing the workpiece.

[0037] In use, the workpiece is first placed stably on the support plate 5. When the clamping mechanism 6 is in the open state, the piston block 13 is pulled outward by the pull rope 4, so that both the cavity 11 and the tubular pad 8 are in a negative pressure state. This causes the pad 9 to be compressed and contracted into the tubular pad 8, preventing obstruction of the workpiece placement. Then, the two first cylinders 2 are activated at the same time to push one end of the clamping mechanism 6 to rotate, so that the other end pressurizes and fixes the workpiece. The piston block 13 is reset, so that the tubular pad 8 becomes a normal pressure state. The pad 9 extends out of the tubular pad 8 through the second spring 14, providing elastic protection for the workpiece.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above" the second feature; "above" and "over" include the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below" the second feature; "below" and "under" include the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
