Description

Technical Field

[0001] This utility model belongs to the field of stainless steel double-walled tube processing, and specifically relates to a tooling for processing stainless steel double-walled tubes. Background Technology

[0002] In modern industry, stainless steel double-walled tubes are widely used in aerospace, energy transmission, food processing, and other industries due to their excellent corrosion resistance, thermal insulation, and mechanical properties. Double-walled tubes consist of an inner and an outer tube, and their unique structure requires careful consideration of the concentricity, assembly accuracy, and connection strength of the inner and outer tubes during processing. Traditional tooling is insufficient to meet the demands of high-precision and high-efficiency production. As industries continuously raise their requirements for product quality and production efficiency, developing specialized tooling capable of precisely positioning and efficiently assembling stainless steel double-walled tubes has become an important direction for optimizing processing technology and driving industry development.

[0003] Although existing stainless steel double-walled pipe processing fixtures can effectively improve production efficiency, ensure the concentricity and assembly accuracy of the inner and outer pipes through precise positioning and stable clamping, and guarantee product quality; some fixtures integrate automated operation functions, reducing manual intervention and labor intensity; and modular design facilitates adaptation to different pipe specifications, improving equipment versatility and processing flexibility, the existing technology cannot effectively achieve rotation and lifting when processing double-walled pipes. This increases the difficulty of work for workers and reduces practicality. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a tooling for processing stainless steel double-walled tubes, so as to solve the problems in processing stainless steel double-walled tubes.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A stainless steel double-walled tube processing fixture includes a fixed base, a worktable fixedly mounted on the upper end of the fixed base, a drive motor fixedly mounted inside the fixed base, a push cylinder fixedly mounted on the output shaft of the drive motor, the push cylinder rotating inside the worktable, a support plate slidably mounted inside the upper end of the worktable, fixed rods fixedly mounted on both sides of the support plate away from the worktable, a lower semi-circular cover integrally formed on the ends of the two fixed rods away from the support plate, an upper semi-circular cover hinged to one side of the two lower semi-circular covers away from the fixed rods, and the side of the upper semi-circular cover away from the hinge point of the lower semi-circular cover engaging with the upper end of the lower semi-circular cover.

[0007] As a preferred technical solution, a square slot is provided at the center of the fixed base, and the drive motor is fixedly installed inside the fixed base through the square slot.

[0008] As a preferred technical solution, a circular groove is provided at the center of the workbench, and the pushing cylinder rotates inside the workbench through the circular groove.

[0009] As a preferred technical solution, the output shaft of the drive motor is fixedly mounted with a stabilizing block, the bottom of the push cylinder is fixedly mounted on the upper end of the stabilizing block, and the output shaft of the drive motor is fixedly connected to the push cylinder through the stabilizing block.

[0010] As a preferred technical solution, limiting plates are fixedly installed on both sides of the upper end of the square groove, and a limiting groove is opened in the center of the limiting plate. The output shaft of the drive motor rotates inside the limiting groove, and the output shaft of the drive motor is fixedly connected to the stabilizing block through the limiting groove.

[0011] As a preferred technical solution, the upper end of the workbench is provided with a mounting groove, the output shaft of the push cylinder is fixedly installed at the center position of the bottom of the support plate, and the support plate is slidably installed inside the upper end of the workbench through the mounting groove.

[0012] As a preferred technical solution, a plug plate is fixedly installed on the upper end of the integrally formed protrusion plate on one side of the lower semi-circular cover. The upper end of the plug plate has slots on both sides, and springs are fixedly installed inside the slots. A locking block is fixedly installed on the end of the spring away from the slot.

[0013] As a preferred technical solution, the upper semi-circular cover has a raised plate on the side away from the hinge, which is the same as the lower semi-circular cover. The raised plate on one side of the upper semi-circular cover has an insertion groove inside. The insertion plate passes through the raised plate on one side of the upper semi-circular cover through the insertion groove. The locking block is engaged with the upper sides of the raised plate on one side of the upper semi-circular cover.

[0014] As a preferred technical solution, a support pad is fixedly installed at the center of the upper end of the support plate, and support legs are fixedly installed around the bottom of the fixed base.

[0015] In summary, the present invention has the following main advantages:

[0016] First, after the drive motor starts, its output shaft rotates, which drives the push cylinder to rotate through the stabilizing block. Since the push cylinder is connected to the circular groove inside the worktable and the drive motor output shaft rotates within the limiting groove of the limiting plate, the stability and accuracy of the rotation are ensured. The rotation of the push cylinder then drives the support plate, the fixing rod, and the double-walled tube clamped in the semi-circular cover to rotate together, so as to realize the angle adjustment of the double-walled tube during the processing to meet different processing requirements.

[0017] Secondly, the upper end of the worktable has a mounting groove, and the output shaft of the push cylinder is fixedly installed at the center of the bottom of the support plate. The support plate is slidably installed inside the upper end of the worktable through the mounting groove. When the piston rod of the push cylinder extends or retracts, the support plate will move up and down, which can effectively adjust the processing position to the optimal position and improve the processing accuracy and efficiency.

[0026] Example

[0027] refer to Figures 1-7This embodiment of a stainless steel double-walled tube processing fixture includes a fixed base 7, a worktable 6 fixedly installed on the upper end of the fixed base 7, a drive motor 19 fixedly installed inside the fixed base 7, a push cylinder 17 fixedly installed on the output shaft of the drive motor 19, the push cylinder 17 rotates inside the worktable 6, a support plate 3 is slidably installed inside the upper end of the worktable 6, and fixed rods 5 are fixedly installed on both sides of the end of the support plate 3 away from the worktable 6, and a lower semi-circular cover 4 is integrally formed on the end of each of the two fixed rods 5 away from the support plate 3, and an upper semi-circular cover 1 is hinged to one side of the two lower semi-circular covers 4 away from the fixed rods 5, and the side of the upper semi-circular cover 1 away from the hinge point of the lower semi-circular cover 4 is engaged and installed on the upper end of the lower semi-circular cover 4.

[0028] refer to Figure 1 , Figures 4 to 7 A square slot 20 is provided at the center of the fixed base 7. The drive motor 19 is fixedly installed inside the fixed base 7 through the square slot 20. A circular slot 15 is provided at the center of the worktable 6. The push cylinder 17 rotates inside the worktable 6 through the circular slot 15. A stabilizing block 16 is fixedly installed on the output shaft of the drive motor 19. The bottom of the push cylinder 17 is fixedly installed on the upper end of the stabilizing block 16. The output shaft of the drive motor 19 is fixedly connected to the push cylinder 17 through the stabilizing block 16. The stabilizing block 16 can improve the hard connection between the drive motor 19 and the push cylinder 17, and can also effectively ensure that the drive motor 19 will not fall off or become unstable when rotating. Limiting plates 18 are fixedly installed on both sides of the upper end of the square slot 20. A limiting slot 21 is provided at the center of the limiting plate 18. The output shaft of the drive motor 19 rotates inside the limiting slot 21. The output shaft of the drive motor 19 is fixedly connected to the stabilizing block 16 through the limiting slot 21. The limiting plate 18 can effectively prevent the output shaft of the drive motor 19 from shifting or shaking.

[0029] refer to Figures 4 to 6 The upper end of the workbench 6 has a mounting groove 14. The output shaft of the push cylinder 17 is fixedly installed at the bottom center of the support plate 3. The support plate 3 is slidably installed inside the upper end of the workbench 6 through the mounting groove 14, which can effectively store the support plate 3 inside the upper end of the workbench 6 for better maintenance.

[0030] refer to Figures 2 to 3A connecting plate 11 is fixedly installed on the upper end of a raised plate 9 integrally formed on one side of the lower semi-circular cover 4. The upper end of the connecting plate 11 has slots 12 on both sides, and springs 13 are fixedly installed inside each slot 12. A locking block 10 is fixedly installed on the end of each spring 13 away from the slot 12. The upper semi-circular cover 1 has a raised plate 9 similar to the lower semi-circular cover 4 on the side away from the hinge. A connecting groove 22 is opened inside the raised plate 9 on one side of the upper semi-circular cover 1, and the connecting plate 11 passes through the connecting groove 22 through the raised plate on one side of the upper semi-circular cover 1. 9. The locking block 10 engages with both sides of the upper end of the protruding plate 9 on one side of the upper semi-circular cover 1, causing the upper semi-circular cover 1 to rotate around the hinge point and close with the lower semi-circular cover 4, forming a complete circular structure that encloses the double-walled tube. At this time, the insertion plate 11 of the lower semi-circular cover 4 is inserted into the insertion groove 22 of the upper semi-circular cover 1, and the spring 13 pushes the locking block 10 to pop out and engage with both sides of the upper end of the protruding plate 9 on one side of the upper semi-circular cover 1, thus achieving a firm engagement between the upper semi-circular cover 1 and the lower semi-circular cover 4, thereby stably clamping the double-walled tube in the tooling.

[0031] refer to Figures 1 to 2 A support pad 2 is fixedly installed at the center of the upper end of the support plate 3, and support legs 8 are fixedly installed around the bottom of the fixed seat 7. The support pad 2 is used to place the pipes to be processed.

[0032] Operating principle and advantages: In use, the fixed base 7 serves as the foundation of the entire fixture, with a worktable 6 fixedly mounted on its upper end. A drive motor 19 is fixedly mounted inside the worktable 6. The output shaft of the drive motor 19 is connected to a push cylinder 17 via a stabilizing block 16, allowing the push cylinder 17 to rotate inside the worktable 6. A support plate 3 is slidably mounted inside the upper end of the worktable 6, sliding under the action of the push cylinder 17. Fixed rods 5 are located on both sides of the end of the support plate 3 furthest from the worktable 6. A lower semi-circular cover 4 is integrally formed at the other end of the fixed rods 5, hinged to an upper semi-circular cover 1. The upper semi-circular cover 1 can be secured by a latch. The upper semicircular cover 1 connects with the lower semicircular cover 4 to form a complete circular structure for clamping the stainless steel double-walled tube. When processing the stainless steel double-walled tube, the double-walled tube is first placed on the placement pad 2 at the center of the upper end of the support plate 3. The placement pad 2 supports and protects the double-walled tube, preventing damage during processing. Then, the worker places the double-walled tube inside the lower semicircular covers 4 on both sides. Next, the upper semicircular cover 1 is rotated around the hinge to close it with the lower semicircular cover 4, forming a complete circular structure that encloses the double-walled tube. At this time, the insertion plate 11 of the lower semicircular cover 4 is inserted into the upper semicircular cover 4. In the insertion slot 22 of cover 1, spring 13 pushes the locking block 10 out, engaging with both sides of the upper end of the protruding plate 9 on one side of the upper semi-circular cover 1, thus achieving a firm engagement between the upper semi-circular cover 1 and the lower semi-circular cover 4, thereby stably clamping the double-walled tube in the tooling. After the drive motor 19 starts, its output shaft rotates, driving the push cylinder 17 to rotate through the stabilizing block 16. Since the push cylinder 17 is connected to the circular groove 15 inside the worktable 6, and the output shaft of the drive motor 19 rotates within the limiting groove 21 of the limiting plate 18, this structural design ensures the stability and accuracy of the rotation. The rotation of the push cylinder 17 then drives the support... The support plate 3, the fixing rod 5, and the double-walled tube clamped in the semi-circular cover rotate together to adjust the angle of the double-walled tube during processing to meet different processing requirements. For example, welding, cutting and other processes may require the double-walled tube to be in different angle positions. The upper end of the worktable 6 has a mounting groove 14. The output shaft of the push cylinder 17 is fixedly installed at the bottom center of the support plate 3. The support plate 3 is slidably installed inside the upper end of the worktable 6 through the mounting groove 14. When the piston rod of the push cylinder 17 extends or retracts, the support plate 3 will move up and down, which can effectively adjust the processing position to the optimal position and improve the processing accuracy and efficiency.
