Description

Technical Field

[0002] Welding is a crucial step in the processing of metal parts. To ensure the quality and efficiency of welding, stable and precise clamping tools are indispensable.

[0003] When using existing clamping tools for welding metal parts, most clamping tools use splint clamping to fix the parts. Although this method can meet the clamping needs of parts to a certain extent, when faced with larger parts, its clamping effect is insufficient. Due to the limited clamping area, large parts are often difficult to maintain stability during the welding process and are prone to deformation or displacement due to uneven force, thus affecting the accuracy and quality of welding.

[0004] Furthermore, existing clamping fixtures generally lack the ability to support parts. During the welding process, parts often need to be held suspended in mid-air, and most clamping fixtures only provide a single clamping force, failing to effectively support and lift the parts. This can easily cause parts to slip due to gravity during welding, which can not only damage the parts but also pose a threat to the operator's safety.

[0005] In view of the above problems, a metal parts welding processing clamping fixture is now designed. Utility Model Content

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] An embodiment of the present application provides a clamping tool for metal parts welding processing, which can solve the problem in the related art that when faced with large parts, the existing clamping tool generally lacks the function of lifting the parts and is unable to effectively support and lift the parts.

[0028] See also Figure 1-Figure 3A metal parts welding processing clamping tool includes: a support beam 1, two clamping arms 2 are provided at the bottom of the support beam 1 for relative sliding, a driving member 3 is provided on the support beam 1, the driving member 3 is connected to the two clamping arms 2 and is used to drive the two clamping arms 2 to expand or retract, a clamping plate 4 is provided at the bottom of the clamping arm 2, the clamping plate 4 is used to clamp parts, and a lifting mechanism 5 is also provided at the bottom of the support beam 1, the lifting mechanism 5 is used to support the clamped parts; the lifting mechanism 5 includes a lifting member 51 and a lifting frame 52, the lifting frame 52 is arranged below the middle of the two clamping plates 4, the lifting member 51 is connected to the lifting frame 52 and is used to drive the lifting frame 52 to rise and fall.

[0029] In actual operation, the driver 3 pushes the clamping arms 2 to move smoothly along the support beam 1. When a part needs to be clamped, the driver 3 drives the two clamping arms 2 toward each other until the clamping plate 4 firmly clamps the part. The clamping plate 4 is the direct component for clamping the part. The shape and size of the clamping plate can be designed according to the specific part to ensure the best clamping effect.

[0030] The tool also features a lifting mechanism 5 to support the clamped parts during welding. This mechanism consists of a lifting member 51 and a lifting frame 52. The lifting member 51 drives the lifting frame 52 upward and downward. The lifting frame 52 is located below and between the two clamping plates 4. Once the part is clamped by the clamping plates, the lifting frame 52 rises to an appropriate height, providing additional support.

[0031] By designing two relatively slidable clamping arms 2, the tooling can adapt to metal parts of different sizes and ensure that the parts can remain stable during the welding process, which greatly improves the accuracy and quality of welding.

[0032] The lifting mechanism 5 provides additional support for the parts, especially when welding large or heavy parts, which helps prevent the parts from being deformed or shifted due to gravity, thereby ensuring the smooth progress of the welding process.

[0033] The automatic control of the driving member 3 makes the movement of the clamping arm 2 and the lifting mechanism 5 more flexible and accurate. The operator only needs to follow simple operating instructions to achieve the clamping and support of the parts, which greatly improves work efficiency.

[0034] Specifically, the driving member 3 in this embodiment includes two cylinders 31 relatively arranged above the support beam 1, two slide rails 32 relatively arranged at the bottom of the support beam 1, a movable platform 33 is slidably arranged on the slide rail 32, and the movable platform 33 is sleeved on the support beam 1, the piston rod of the cylinder 31 is connected to the corresponding movable platform 33, and the clamping arm 2 is arranged below the movable platform 33.

[0035] The two cylinders 31 are relatively arranged above the support beam 1. This layout ensures that the cylinders 31 can generate sufficient horizontal thrust to drive the clamping arm 2 to expand or retract along the slide rail 32 at the bottom of the support beam 1.

[0036] The piston rod of the cylinder 31 is connected to the corresponding moving platform 33, which is sleeved on the support beam 1 and can slide smoothly on the slide rail 32, so that the thrust of the cylinder 31 can be directly transmitted to the moving platform 33, thereby driving it to move horizontally along the slide rail 32.

[0037] When the piston rod of the cylinder 31 extends or retracts, the moving platform 33 moves accordingly, thereby driving the clamping arm 2 to expand or retract along the slide rail 32 .

[0038] Further, such as Figure 3 As shown, the movable platform 33 includes a slide plate slidably arranged on the top of the slide plate, two support plates are arranged opposite to each other on the top of the slide plate, the two support plates on the same side are arranged on both sides of the support beam 1, and a connecting shaft is provided between the tops of the two support plates on the same side, and the piston rod of the cylinder 31 is sleeved on the connecting shaft.

[0039] When a metal part needs to be clamped, the piston rod of the cylinder 31 extends, pushing the movable platform 33 toward the center along the slide rail 32. As the movable platform 33 moves, the clamping arms 2 gradually move closer until the clamping plates 4 firmly clamp the metal part. When the metal part needs to be released, the piston rod of the cylinder 31 retracts, pulling the movable platform 33 outward along the slide rail 32, which in turn causes the clamping arms 2 to gradually expand.

[0040] In one embodiment, Figure 1 and Figure 4 As shown, the clamping arm 2 includes a mechanical arm 21 arranged at the bottom of the movable platform 33, and a slide 22 is sleeved on the bottom of the mechanical arm 21. A cylinder 23 is also provided on the mechanical arm 21. The piston rod of the cylinder 23 is connected to the corresponding slide 22 and is used to control the lifting and lowering of the slide 22; the two clamps 4 are arranged in the middle of the two slides 22.

[0041] To clamp a metal part, the robot arm 21 is first moved to the appropriate position through the collaboration of the movable table 33 and the cylinder 31. Then, the piston rod of the second cylinder 23 extends, pushing the slide 22 and the clamping plate 4 toward the metal part. When the clamping plate 4 contacts the metal part and generates sufficient clamping force, the piston rod of the second cylinder 23 stops extending, and the metal part is now firmly clamped between the clamping plates 4. When the metal part needs to be released, the piston rod of the second cylinder 23 retracts, pulling the slide 22 and the clamping plate 4 away from the metal part, thereby releasing the part.

[0042] As a preferred embodiment, Figure 1 and Figure 4 As shown, a rotating member 6 is further provided, wherein the rotating member 6 includes a rotating shaft 61 rotatably provided on the slide 22, both ends of the rotating shaft 61 extend outward, and the clamping plate 4 is provided at one end of the rotating shaft 61, and the two clamping plates 4 are arranged opposite to each other;

[0043] A driving motor 63 is provided on one side of the slide 22 , and an output shaft of the driving motor 63 is connected to one end of any rotating shaft 61 .

[0044] Rotating member 6 primarily consists of a shaft 61 and a drive motor 63. Shaft 61 is rotatably mounted on slide 22, with both ends extending outward, providing a mounting base for clamping plates 4. Two clamping plates 4 are positioned at opposite ends of shaft 61, ensuring they can simultaneously clamp two opposing surfaces of a metal part.

[0045] A drive motor 63 is mounted on one side of the slide 22, with its output shaft connected to one end of each shaft 61. When the drive motor 63 is activated, it rotates the shaft 61, which in turn rotates the clamping plate 4. This design allows the clamping plate 4 to be fine-tuned to the shape and size of the metal part when clamping it, ensuring optimal grip.

[0046] When the clamping plates 4 come into contact with the metal part and generate sufficient clamping force, the drive motor 63 can be started to fine-tune the clamping plates 4 as needed to ensure that the metal part is firmly and accurately clamped between the clamping plates 4. When the metal part needs to be released, the piston rod of the second cylinder 23 retracts, pulling the slide 22 and the clamping plates 4 away from the metal part, and the drive motor 63 stops working.

[0047] In one embodiment, Figure 2 and Figure 5 As shown, the lifting member 51 includes a fixing frame 511 arranged at the bottom of the support beam 1, the fixing frame 511 is U-shaped, and is arranged between the two clamping arms 2, and a cylinder three 512 is provided on the fixing frame 511, and the bottom end of the piston rod of the cylinder three 512 is connected to the lifting frame 52.

[0048] Lifting member 51 primarily consists of a fixed frame 511 and a cylinder 512. Fixed frame 511 is U-shaped and securely attached to the bottom of support beam 1, positioned between two clamping arms 2. This design ensures the stability and support of lifting member 51, enabling it to withstand the weight of lifting frame 52 and the metal components mounted thereon.

[0049] Cylinder three 512 is mounted on the fixed frame 511, with the bottom end of its piston rod connected to the lifting frame 52. When the piston rod of cylinder three 512 extends, it pushes the lifting frame 52 upward; when the piston rod retracts, it pulls the lifting frame 52 downward. This design allows the lifting frame 52 to move smoothly vertically, enabling flexible lifting of metal parts of varying heights.

[0050] During operation, when a metal part needs to be lifted, the piston rod of cylinder three 512 is first extended, pushing the lifting frame 52 up to the appropriate height. Then, the clamping arm 2, through the collaboration of the movable platform 33, cylinder 31, and cylinder two 23, moves the clamping plates 4 to either side of the metal part, generating sufficient clamping force. At this point, the metal part is securely clamped between the clamping plates 4 and supported by the lifting frame 52. When the metal part needs to be released, the piston rod of cylinder three 512 is retracted, driving the lifting frame 52 down. Simultaneously, the clamping arm 2 releases the clamping plates 4, thereby releasing the metal part.

[0051] In one embodiment, Figure 2 and Figure 5 As shown, the lifting frame 52 includes a sleeve 521 relatively embedded in the fixed frame 511, a connecting rod 522 is inserted into the sleeve 521, a lifting plate 523 is set between the bottom ends of the two connecting rods 522, the lifting plate 523 is located between the two clamping plates 4, and a transmission plate 524 is set between the tops of the two connecting rods 522. The transmission plate 524 is U-shaped and surrounds the outside of the cylinder 3 512; the piston rod of the cylinder 3 512 is connected to the lifting plate 523. The fixed frame 511 is provided with a through hole for accommodating the piston rod.

[0052] The design of the connection between sleeve 521 and connecting rod 522: Sleeve 521 is embedded in the fixed frame 511, providing stable support and guidance for connecting rod 522. Connecting rod 522 is inserted into sleeve 521 and secured by bolts or pins to prevent it from sliding or rotating inside sleeve 521. This design allows for smooth vertical movement of lifting frame 52 while improving its overall stability.

[0053] The connection between the lifting plate 523 and the connecting rods 522: A lifting plate 523 is provided between the bottom ends of the two connecting rods 522. Positioned between the two clamping plates 4, this lifting plate 523 directly supports the metal parts. The design of the lifting plate 523 can be adjusted to the shape and size of the metal parts to ensure optimal support. Furthermore, the lifting plate 523 can be made of high-performance materials such as wear-resistant and heat-resistant materials to enhance its service life and durability.

[0054] Design of the transmission plate 524: A U-shaped transmission plate 524 is positioned between the tops of the two connecting rods 522 and surrounds the outside of cylinder three 512. The design of the transmission plate 524 not only enhances the overall stability of the lifting frame 52 but also allows the piston rod of cylinder three 512 to connect directly to it. When the piston rod of cylinder three 512 extends or retracts, it pushes or pulls the connecting rods 522 and the lifting plate 523 through the transmission plate 524, causing them to move upward or downward. This design simplifies the lifting mechanism of the lifting frame 52, improving its efficiency and reliability.

[0055] Connection between the piston rod of cylinder three 512 and lifting plate 523: The piston rod of cylinder three 512 is directly connected to lifting plate 523. This design ensures that the piston rod's thrust and pull forces are directly transmitted to lifting plate 523, thereby achieving stable lifting of metal parts. Furthermore, the through-holes in the fixing frame 511 allow the piston rod to pass smoothly through, ensuring that the lifting and lowering movement of the lifting frame 52 is unimpeded.
