Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment, and specifically relates to a welding device for long strip-shaped workpieces. Background Technology

[0002] Welding involves heating the joint area of ​​a workpiece using heat sources such as flames, electric arcs, lasers, or resistance thermometers. This raises the temperature until it reaches the material's melting point, intensifying atomic activity and creating conditions for atomic diffusion and bonding. Welding can connect disparate components into a complete structure, ensuring its strength and stability. However, when welding long, rectangular workpieces, they need to be pressed and fixed. Current technology typically only allows for clamping and fixing workpieces of specific lengths.

[0003] Referring to Chinese patent document CN218556061U, entitled "A Welding Fixture for Screw Plates," the fixture includes a welding seat, a receiving groove, a positioning block, a pressure plate, and a locking bolt. The welding seat has a receiving groove and a positioning block, arranged symmetrically in two sets for holding two long strips. The pressure plate is detachable for pressing the two long strips, and a locking bolt is installed on the pressure plate. In use, the two long strips are initially positioned by abutting against the receiving groove and the positioning block, respectively. Then, the pressure plate is pressed onto the two long strips to further fix them, and the locking bolt is used to secure the pressure plate. The locking bolt's helix passes through a helical groove in the welding seat. Finally, the two workpieces are welded together using a welding component.

[0004] Referring to the above technical solution, before welding long strip-shaped workpieces, the workpieces are placed in a specific receiving groove for preliminary positioning, and then pressure plates and locking bolts are used to further fix the workpieces to facilitate subsequent welding. However, the equipment can only weld long strip-shaped workpieces of the same specification. For workpieces of other specifications, the equipment needs to be changed, and when welding the front and back sides of the workpiece, manual flipping is required, which is cumbersome. Therefore, this utility model provides a welding device for long strip-shaped workpieces to solve the problems existing in the prior art. Utility Model Content

[0005] The technical problem to be solved by this utility model is that it can not only adapt the device to welding long strip workpieces of different lengths and specifications, thus enhancing the practicality of the device, but also easily achieve the flipping of the workpiece, reducing labor intensity.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a welding device for a long strip workpiece, including a worktable and a welding component. The welding component is used to weld the long strip workpiece. Two sets of clamping assemblies for clamping the workpiece are installed on the worktable. The clamping assembly includes a support plate installed on the worktable, a rotating plate installed on the support plate, a fixed clamping plate and a sliding clamping plate installed on the rotating plate, and a telescopic sleeve provided on both the fixed clamping plate and the sliding clamping plate. A telescopic rod is slidably installed inside the telescopic sleeve, and a clamping block for clamping and fixing the middle part of the long strip workpiece is installed on the telescopic rod.

[0007] By adopting the above technical solution, the rotating plate can drive the workpiece to flip, allowing for easy welding of the front and back sides or all four sides of the workpiece, thus improving welding efficiency. Simultaneously, the sliding clamping plate, in conjunction with the fixed clamping plate, can clamp and fix long strip-shaped workpieces of different thicknesses. By adjusting the position of the telescopic rod within the telescopic sleeve, the clamping blocks can further support and clamp the middle or near the welding end of workpieces of different lengths, enhancing the stability of the workpiece during welding.

[0008] Optionally, the two sets of clamping components are respectively configured as sliding clamping parts and fixed clamping parts, and a driving component is installed on the worktable to drive the sliding clamping parts to move.

[0009] By adopting the above technical solution, the sliding clamping component can move closer to or further away from the fixed clamping component under the drive of the driving component, which enables the device to weld long strip workpieces of different lengths and specifications, thus enhancing the versatility and practicality of the device.

[0010] Optionally, the driving component includes a slide groove on the worktable, a T-shaped slider at the bottom of the sliding clamp, a motor mounted on the worktable, a lead screw connected to the output shaft of the motor inside the slide groove, and the lead screw passing through the T-shaped slider to drive the T-shaped slider to slide.

[0011] By adopting the above technical solution, the lead screw can be rotated around its own axis under the drive of the motor, and the T-shaped slider can drive the sliding clamping part to move closer to or away from the fixed clamping part under the limit of the slide groove.

[0012] Optionally, both the telescopic sleeve and the telescopic rod are provided with locking holes, and locking bolts are installed in the locking holes.

[0013] By adopting the above technical solution, the locking bolt can fix the telescopic rod to the telescopic sleeve, preventing the telescopic rod from moving during welding and thus improving the stability of the workpiece during welding. At the same time, the locking bolt also facilitates the user's adjustment and fixation of the clamping components, improving the ease of use of the device.

[0014] Optionally, a motor is installed on the support plate to drive the rotating plate to rotate.

[0015] By adopting the above technical solution, the rotating plate can be driven by the second motor to rotate the workpiece, thereby realizing the automatic flipping of the workpiece, which facilitates welding of the front and back or all four sides of the workpiece and improves welding efficiency.

[0016] Optionally, friction pads are installed on the fixed clamping plate, the sliding clamping plate, and the clamping block.

[0017] By adopting the above technical solution, the friction pad can increase the friction between the workpiece and the clamping assembly, and prevent the workpiece from sliding during the welding process.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By moving the sliding clamping component closer to or further away from the fixed clamping component, the clamping assembly can clamp long strip workpieces of different lengths. Through the cooperation of the sliding clamping plate and the fixed clamping plate, long strip workpieces of different thicknesses can be clamped and fixed. Compared with the traditional technology where the equipment can only clamp workpieces of a specific length, this device can adapt to welding long strip workpieces of different lengths and thicknesses, thus enhancing the practicality and versatility of the device.

[0019] 2. The two workpieces can be rotated synchronously by the symmetrical rotating plates on both sides, which makes it easy to weld the front and back or all four sides of the workpiece, reducing labor costs and improving welding efficiency.

[0020] 3. By setting up the telescopic sleeve, telescopic rod and clamping block, when welding long strip workpieces of different lengths, the position of the telescopic rod in the telescopic sleeve can be adjusted to adapt to the length of the workpiece, so that the clamping block can provide support and clamp and fix the middle of the workpiece or near the welding end, ensuring the stability of the workpiece during the welding process.

Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0025] like Figure 1-4 As shown, a welding device for elongated workpieces includes a worktable 100, a clamping assembly 200, a driving component 300, and a welding component 400. The clamping assembly 200 consists of a sliding clamping component 201 and a fixed clamping component 202. The sliding clamping component 201 and the fixed clamping component 202 are symmetrically mounted on the worktable 100 with identical structures for clamping and fixing two elongated workpieces. The driving component 300 is mounted on the worktable 100 to move the sliding clamping component 201 away from or towards the fixed clamping component 202. The welding component 400 is disposed on the worktable 100 for welding the connection between the two workpieces.

[0026] like Figure 1 and Figure 2 As shown, the clamping assembly 200 includes a support plate 203, a second motor 212, a rotating plate 204, a fixed clamping plate 205, and a sliding clamping plate 206. The support plate 203 on the sliding clamping member 201 is slidably mounted on the worktable 100, and the support plate 203 on the fixed clamping member 202 is fixedly mounted on the worktable 100. The second motor 212 is mounted on the upper part of the support plate 203, and the rotating plate 204 is connected to the output shaft of the second motor 212. The fixed clamping plate 205 is fixedly mounted on the rotating plate 204, and the sliding clamping plate 206 is slidably disposed on the rotating plate 204, with the sliding clamping plate 206 being close to or away from the fixed clamping plate 205.

[0027] like Figure 3As shown, the clamping assembly 200 also includes a telescopic sleeve 207, a telescopic rod 208, a clamping block 209, a friction pad 213, a locking hole 210, and a locking bolt 211. Two telescopic sleeves 207 are provided on both the fixed clamping plate 205 and the sliding clamping plate 206. A telescopic rod 208 is slidably installed inside the telescopic sleeve 207. A clamping block 209 is fixedly installed at the end of the telescopic rod 208. The clamping block 209 is horizontal to both the fixed clamping plate 205 and the sliding clamping plate 206. While the fixed clamping plate 205 and the sliding clamping plate 206 clamp the workpiece, the clamping block 209 can clamp and fix the middle or welding end of the workpiece. Friction pads 213 are installed on the fixed clamping plate 205, the sliding clamping plate 206, and the clamping block 209 to ensure the stability of the workpiece clamping during the welding process. The locking holes 210 are arranged in a multiple even array on the telescopic sleeve 207 and the telescopic rod 208. Locking bolts 211 are installed on the locking holes 210. The locking bolts 211 are U-shaped. One locking bolt 211 can lock the telescopic sleeve 207 and the telescopic rod 208 on the same horizontal plane at the same time, which is convenient for the staff to operate.

[0028] As shown in the figure, the driving component 300 includes a slide groove 301, a T-shaped slider 302, a motor 303, and a lead screw 304. The slide groove 301 is horizontally formed on the worktable 100. The T-shaped slider 302 is fixedly installed at the bottom of the support plate 203 in the sliding clamping component 201. The motor 303 is set on the side wall of the worktable 100. The lead screw 304 is connected to the output shaft of the motor 303. A screw spool that meshes with the lead screw 304 is provided on the T-shaped slider 302. The lead screw 304 passes through the screw spool of the T-shaped slider 302. By rotating the motor 303 forward or backward, the sliding clamping component 201 can move closer to or further away from the fixed clamping component 202.

[0029] like Figure 4 As shown, the welding component 400 includes a horizontal sliding module 401, a vertical sliding module 402, a longitudinal sliding module 403, an extension plate 404, and a welding pen 405. The horizontal sliding module 401, vertical sliding module 402, and longitudinal sliding module 403 each consist of a support frame, a motor, a rotating lead screw, and a slider. The extension plate 404 is mounted on the longitudinal sliding module 403, and the welding pen 405 is disposed on the extension plate 404 for welding two elongated workpieces.

[0030] Working principle: In use, firstly, adjust the length of the telescopic rod 208 extending beyond the telescopic sleeve 207 according to the length of the workpiece, so that the clamping block 209 can clamp the middle part of the workpiece or the part near the welding end. Then, place the two long strip workpieces between the fixed clamping plate 205 and the sliding clamping plate 206 of the two sets of clamping components 200 respectively. Move the sliding clamping plate 206 according to the thickness of the long strip workpiece. At this time, the fixed clamping plate 205 and the sliding clamping plate 206 clamp and fix the end of the workpiece that does not need to be welded, and the clamping blocks 209 distributed vertically clamp and fix the middle part of the workpiece or the part near the welding end.

[0031] Next, based on the length of the workpiece, motor 303 is started. Motor 303 drives the lead screw 304 to rotate. Under the limit of the slide groove 301, the T-shaped slider 302 drives the sliding clamp 201 to move, so that the workpiece on the sliding clamp 201 gradually approaches the workpiece on the fixed clamp 202, allowing the welding part 400 to weld the two workpieces. After one side is welded, motor 212 is started. Motor 212 drives the rotating plate 204 to rotate, and the rotating plate 204 causes the workpiece to flip, so that the welding part 400 completes the welding of the front and back or all four sides of the workpiece. Finally, the workpiece can be removed.

[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
