Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a laser welding tooling and fixture. Background Technology

[0002] Laser welding is a modern welding technology that uses a high-energy-density laser beam as a heat source to join materials. It focuses the laser beam to a very small point, typically less than 1 millimeter in diameter, or even smaller, generating extremely high local temperatures in a very short time, causing the materials to be welded to melt and form a strong joint.

[0003] Laser welding fixtures are auxiliary tools specifically designed and manufactured for laser welding processes. They are used to precisely and securely fix the workpiece to be welded during the welding process. They ensure the positional accuracy and stability of the workpiece during welding, thereby guaranteeing the consistency and reliability of the weld quality.

[0004] Existing laser welding fixtures mostly use manual knobs, screws, or spring clamping for clamping, requiring operators to apply continuous pressure to complete the clamping action. Prolonged operation can easily lead to fatigue and affect work efficiency. Moreover, for unskilled workers, the operation is cumbersome and prone to errors. When in use, the structure needs to be further processed and improved, increasing the number of steps and reducing work efficiency. To address these issues, the inventors have proposed a laser welding fixture to solve the aforementioned technical problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] A laser welding fixture includes a chuck, a support rod, and an adjusting block. One end of the chuck is a support platform. The support rod abuts against the surface of the support platform via a buffer rod. The adjusting block has a contraction groove in the middle, which is an inverted trapezoidal structure. The inner surface of the contraction groove fits against the outer surface of the support rod. Limiting holes are provided on the surfaces of both the adjusting block and the support rod. The limiting holes are through-holes. The adjusting block limits the position of the support rod through the limiting holes via a limiting rod. The surface of the chuck is equipped with a detachable anti-slip structure.

[0007] This structure uses an adjusting block that slides on the surface of the support rod. By aligning the limiting hole on the surface of the adjusting block with the limiting hole on the surface of the support rod, and inserting the limiting rod into the limiting hole, the limiting rod can limit the position of the support rod. In addition, since the shrinkage groove has an inverted trapezoidal structure, it can adjust the opening degree between the two support rods when the adjusting block moves, so as to clamp the corresponding parts. This structure uses a simple adjustment method to adjust the opening degree of the clamp, reducing the traditional manual clamping process and freeing the operator's hands, avoiding fatigue caused by continuous application of force.

[0008] The chuck, as a clamping component, is used to fix the parts to be welded, while the support platform provides a support platform for the support rod to ensure the stability of the clamping action. The anti-slip structure is installed on the surface of the chuck to enhance the clamping stability and prevent the parts from slipping during the welding process. By inserting the limit rod into the limit hole, the position of the fixture can be quickly locked, which facilitates the clamping or processing of subsequent processes.

[0009] Furthermore, the anti-slip structure includes an anti-slip wedge and a locking block, which are integrally formed. The surface of the chuck is provided with a locking groove for matching and installing with the locking block. The surface of the chuck is provided with a clearance groove for reducing heat transfer. The locking groove passes through one end of the clearance groove. The top of the chuck is provided with an anti-slip rubber block for matching with the anti-slip wedge.

[0010] Anti-slip wedges and locking blocks provide the main clamping friction, ensuring that the workpiece is less likely to slip during welding. The one-piece molding design improves the overall strength and durability of the structure and reduces the risk of loosening or failure due to improper assembly. The anti-slip wedges, locking blocks and anti-slip rubber blocks work together to form a multi-layered anti-slip system, ensuring that the workpiece remains stable during welding. The clearance groove effectively reduces the transmission of high temperature during welding and maintains the operating temperature of the fixture within a safe range.

[0011] Furthermore, the support rod has a symmetrical structure, and adjacent support rods are connected by a limiting plate. The surface of the limiting plate is connected to a rotating shaft to assist the movement of the support rod. The support rod moves in a circle around the rotating shaft as the center point. The rotating shaft serves as the rotation center of the support rod, providing multiple angle adjustment possibilities, allowing the fixture to clamp workpieces of more than one geometric shape. The limiting plate not only serves as a connection but also provides additional support and guiding functions to ensure that the support rod remains stable during rotation.

[0012] Furthermore, the limiting holes are arranged in a linear pattern, with the distance between two adjacent limiting holes being equal. The diameter of the top of one end of the limiting rod is larger than the diameter of the limiting hole, while the diameter of the other end of the limiting rod is the same as that of the limiting hole. The limiting rod and the limiting hole are detachable.

[0013] The linear arrangement allows operators to more intuitively select the appropriate limiting hole for locking, reducing the difficulty of operation. When the position of the support rod needs to be adjusted, simply pull out the limiting rod and reinsert it into the appropriate limiting hole. This structure adopts a simple and quick operation method, reducing training time and allowing operators to become more proficient in a short period of time, thereby reducing training costs.

[0014] Furthermore, the adjusting block has a U-shaped structure. One end of the adjusting block near the support platform has a groove for assisting the adjusting block in locking onto the surface of the support platform. The surface of the groove is provided with a limiting rubber block to increase friction. When the groove fits the contour of the support platform, it enhances the contact area. The two ends of the adjusting block support the support platform, reducing uneven force and preventing tilting or misalignment. The limiting rubber block embedded in the groove increases friction, achieving anti-slip and locking effects, and further limiting the position.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the structure uses an adjusting block to slide on the surface of the support rod, and aligns the limiting hole on the surface of the adjusting block with the limiting hole on the surface of the support rod, and inserts the limiting rod into the limiting hole, so that the limiting rod can play the role of limiting the position of the support rod.

[0016] In addition, since the shrink groove is an inverted trapezoidal structure, when the adjusting block moves, it can adjust the opening and closing degree between the two support rods so as to clamp the corresponding parts. This structure adopts a simple adjustment method to adjust the opening and closing degree of the clamp, reducing the traditional manual clamping process and freeing the operator's hands, avoiding fatigue caused by continuous application of force.

[0017] When the position of the support rod needs to be adjusted, this structure can be easily adjusted by simply pulling out the limit rod and re-inserting it into the appropriate limit hole. This structure adopts a simple and quick operation method, reducing training time and allowing operators to become more proficient in a short period of time, thereby reducing training costs.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] For this embodiment, please refer to Figures 1-6 The present invention relates to a laser welding fixture, comprising a chuck 1, a support rod 2, and an adjusting block 3. One end of the chuck 1 is a support platform 4. The support rod 2 abuts against the surface of the support platform 4 via a buffer rod 5. A shrinkage groove 6 is provided in the middle of the adjusting block 3. The shrinkage groove 6 has an inverted trapezoidal structure. The inner surface of the shrinkage groove 6 fits against the outer surface of the support rod 2. Limiting holes 7 are provided on the surfaces of both the adjusting block 3 and the support rod 2. The limiting holes 7 have a through structure. The adjusting block 3 limits the position of the support rod 2 by passing through the limiting holes 7 via a limiting rod 8. A detachable anti-slip structure is installed on the surface of the chuck 1.

[0027] This structure uses an adjusting block 3 that slides on the surface of the support rod 2. By aligning the limiting hole 7 on the surface of the adjusting block 3 with the limiting hole 7 on the surface of the support rod 2, and inserting the limiting rod 8 into the limiting hole 7, the limiting rod 8 can limit the position of the support rod 2. In addition, since the shrinkage groove 6 has an inverted trapezoidal structure, it can adjust the opening degree between the two support rods 2 when the adjusting block 3 moves, so as to clamp the corresponding parts. This structure uses a simple adjustment method to adjust the opening degree of the clamp, reducing the traditional manual clamping process and freeing the operator's hands, avoiding fatigue caused by continuous application of force.

[0028] The chuck 1 serves as a clamping component to fix the parts to be welded, while the support platform 4 provides a support platform for the support rod 2 to ensure the stability of the clamping action. An anti-slip structure is installed on the surface of the chuck 1 to enhance the clamping stability and prevent the parts from slipping during the welding process. The position of the fixture is quickly locked by inserting the limiting rod 8 into the limiting hole 7, which facilitates the clamping or processing of subsequent processes.

[0029] The anti-slip structure includes an anti-slip wedge 9 and a locking block 10, which are integrally formed. The surface of the chuck 1 is provided with a locking groove 11 that is matched and installed with the locking block 10. The surface of the chuck 1 is provided with a clearance groove 12 for reducing heat transfer. The locking groove 11 passes through one end of the clearance groove 12. The top of the chuck 1 is provided with an anti-slip rubber block 13 that is matched with the anti-slip wedge 9.

[0030] The anti-slip wedge 9 and the locking block 10 provide the main clamping friction, ensuring that the workpiece is less likely to slip during the welding process. The one-piece molding design improves the overall strength and durability of the structure and reduces the risk of loosening or failure due to improper assembly. The anti-slip wedge 9, the locking block 10 and the anti-slip rubber block 13 work together to form a multi-layered anti-slip system, ensuring that the workpiece remains stable during the welding process. The clearance groove 12 effectively reduces the transmission of high temperature during the welding process and maintains the working temperature of the fixture within a safe range.

[0031] The support rod 2 has a symmetrical structure, and two adjacent support rods 2 are connected by a limiting plate 14. The surface of the limiting plate 14 is connected to a rotating shaft 15 for assisting the movement of the support rod 2. The support rod 2 moves in a circle with the rotating shaft 15 as the center point. The rotating shaft 15 serves as the rotation center of the support rod 2, providing multiple angle adjustment possibilities, so that the fixture can clamp workpieces of more than one geometric shape. The limiting plate 14 not only plays a connecting role, but also provides additional support and guiding functions to ensure that the support rod 2 remains stable during rotation.

[0032] The limiting holes 7 are arranged in a linear pattern, and the distance between two adjacent limiting holes 7 is equidistant. The diameter of the top of one end of the limiting rod 8 is larger than the diameter of the limiting hole 7, and the other end of the limiting rod 8 is the same as the diameter of the limiting hole 7. The limiting rod 8 and the limiting hole 7 are detachable.

[0033] The linear arrangement allows operators to more intuitively select the appropriate limiting hole 7 for locking, reducing the difficulty of operation. When the position of the support rod 2 needs to be adjusted, simply pull out the limiting rod 8 and reinsert it into the appropriate limiting hole 7. This structure adopts a simple and quick operation method, reducing training time and allowing operators to become more proficient in a short period of time, thereby reducing training costs.

[0034] The adjusting block 3 has a U-shaped structure. One end of the adjusting block 3 near the support platform 4 has a groove 16 for assisting the adjusting block 3 in clamping the surface of the support platform 4. The surface of the groove 16 is provided with a limiting rubber block 17 for increasing friction. When the groove 16 fits the contour of the support platform 4, it enhances the contact area. The two ends of the adjusting block 3 support the support platform 4, reducing uneven force and preventing tilting or misalignment. The limiting rubber block 17 is embedded in the groove 16, which increases friction, achieves anti-slip and locking effects, and further limits the position.

[0035] The key design feature of this utility model is that: while the adjusting block 3 slides on the surface of the support rod 2, the limiting hole 7 on the surface of the adjusting block 3 is aligned with the limiting hole 7 on the surface of the support rod 2, and the limiting rod 8 is inserted into the limiting hole 7, so that the limiting rod 8 can limit the position of the support rod 2.

[0036] In addition, since the shrinkage groove 6 has an inverted trapezoidal structure, when the adjusting block 3 moves, it can adjust the opening and closing degree between the two support rods 2 so as to clamp the corresponding parts. This structure adopts a simple adjustment method to adjust the opening and closing degree of the clamp, reducing the traditional manual clamping process and freeing the operator's hands, avoiding fatigue caused by continuous application of force.

[0037] When the position of the support rod 2 needs to be adjusted, simply pull out the limit rod 8 and reinsert it into the appropriate limit hole 7. This structure adopts a simple and quick operation method, reducing training time and allowing operators to become more proficient in a short period of time, thereby reducing training costs.

[0038] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
