Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and in particular to a welding device for stud processing. Background Technology

[0002] Stud welding is a method of welding in which one end of a stud is brought into contact with the surface of a plate (or pipe), an electric arc is ignited, and after the contact surface melts, a certain pressure is applied to the stud to complete the welding. Arc stud welding with cylindrical head studs is suitable for high-rise steel-framed buildings, industrial plants, highways, railways, bridges, towers, automobiles, energy and transportation facilities, airports, stations, power plants, pipe supports, lifting machinery, and other steel structures.

[0003] Most improvements to welding equipment in the prior art focus on increasing welding efficiency. For example, Chinese patent document CN219805507U discloses a stud welding device, including a worktable. The worktable includes a moving mechanism and a feeding mechanism. A support column is fixedly installed at the top of the worktable, and a support platform is fixedly installed at the top of the support column. A first electric cylinder is installed through the outside of the support platform. By adopting the above technical solution and setting up the moving mechanism, a second electric cylinder drives the first push column to slide, the first push column drives the first moving plate to slide, the first moving plate drives the second limiting plate to slide, a third electric cylinder drives the second moving plate to slide, and the second moving plate drives the welding plate to move. This facilitates the movement of the metal plate and the continuous welding on the metal plate. After one welding is completed, the moving mechanism moves once, facilitating the next welding, thereby improving the welding efficiency and reliability of the device, significantly reducing labor costs, and achieving more precise welding than manual welding.

[0004] While the aforementioned device has certain advantages in improving welding efficiency, it still has shortcomings:

[0005] The aforementioned device lacks protective measures. If the welding plate is not fitted with studs or the studs fall off, the feeding mechanism will come into contact with the welding plate, forming a welding circuit, which poses a certain safety hazard. Utility Model Content

[0006] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a welding device for stud processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a welding device for stud processing, comprising a support rod, a placement plate, a transmission mechanism, and a welding mechanism. Multiple sets of support rods are fixedly connected to the bottom of the placement plate and distributed at the four corners of the bottom of the placement plate. A transmission mechanism is provided at the top of the placement plate. The welding mechanism is located at the top of the placement plate and at the rear end of the transmission mechanism. The welding mechanism includes a support column, a support plate, an electric cylinder, a telescopic rod, an outer sheath, a welding rod, and a welding head. The top of the support column is fixedly connected to the bottom of the support plate. An electric cylinder is placed at the top of the support plate and is connected to the telescopic rod via a transmission mechanism. An outer sheath is fixedly connected to the bottom of the telescopic rod. A welding rod is disposed inside the outer sheath. The top of the welding rod is fixedly connected to the bottom of the telescopic rod, and a welding head is fixedly connected to the bottom of the welding rod.

[0008] As a further embodiment of this utility model, the support column is fixedly connected to the top of the placement plate, and the support column is used to support the entire welding mechanism.

[0009] As a further embodiment of this utility model, the telescopic rod penetrates through the support plate and reaches the lower end of the support plate.

[0010] As a further embodiment of this utility model, the transmission mechanism includes a drive motor, a threaded shaft, a limiting plate, a lead screw, and a moving plate. The drive motor is connected to the threaded shaft via a coupling. Two sets of limiting plates are provided, arranged symmetrically on the left and right sides. The two sets of limiting plates are fixedly connected to the top of the placement plate. The threaded shaft passes through one set of limiting plates, and its end is connected to the other set of limiting plates. Two sets of lead screws are provided between the two sets of limiting plates, and the two sets of lead screws are distributed on the left and right sides of the threaded shaft. The outer surfaces of the threaded shaft and the two sets of lead screws are connected to the moving plate. The transmission device is used to adjust the position of the welding operation.

[0011] As a further embodiment of this utility model, the top of the movable plate is provided with multiple sets of placement holes, which are used to place studs.

[0012] As a further embodiment of this invention, the diameter of the outer sheath is larger than the diameter of the placement hole.

[0013] As a further embodiment of this utility model, the length of the welding rod and the welding head is less than the length of the outer sheath. Since the length of the welding rod and the welding head is less than the length of the outer sheath, it means that if the bottom of the outer sheath is in complete contact with the moving plate, and if the placement hole on the moving plate is not filled with a stud or the stud falls off, the welding head will not contact the moving plate.

[0014] Compared with the prior art, this utility model provides a welding device for stud processing, which has the following features:

[0015] Beneficial effects:

[0016] In this invention, a welding mechanism is provided at the upper end of the placement plate. Through the cooperation of the telescopic rod and the outer sheath, the outer sheath can completely surround the threaded post placed in the placement hole when the user is performing welding work, thereby enabling welding. The outer sheath improves the safety of the welding work. At the same time, since the length of the welding rod and the welding head is less than that of the outer sheath, it means that even if the bottom of the outer sheath is in complete contact with the moving plate, if the placement hole on the moving plate does not contain a threaded post or the threaded post falls off, the welding head will not come into contact with the moving plate to form a welding circuit, reducing the risk and improving the safety of the device.

[0027] A welding device for stud processing includes a support rod 1, a placement plate 2, and a transmission mechanism 3. The support rod 1 is provided in multiple sets, and the multiple sets of support rod 1 are fixedly connected to the bottom of the placement plate 2 and distributed at the four bottom corners of the placement plate 2. The transmission mechanism 3 is provided on the top of the placement plate 2.

[0028] Please see Figure 3-4 In this embodiment of the utility model, a welding mechanism 4 is also included. The welding mechanism 4 is disposed on the top of the placement plate 2 and placed at the rear end of the transmission mechanism 3. The welding mechanism 4 includes a support column 41, a support plate 42, an electric cylinder 43, a telescopic rod 44, an outer sheath layer 45, a welding rod 46, and a welding head 47. The top end of the support column 41 is fixedly connected to the bottom of the support plate 42. The electric cylinder 43 is placed on the top of the support plate 42 and is connected to the telescopic rod 44. The bottom of the telescopic rod 44 is fixedly connected to the outer sheath layer 45. The welding rod 46 is disposed inside the outer sheath layer 45. The top end of the welding rod 46 is fixedly connected to the bottom of the telescopic rod 44, and the bottom end of the welding rod 46 is fixedly connected to the welding head 47.

[0029] Please see Figure 1-4 In this embodiment of the utility model: the support column 41 is fixedly connected to the top of the placement plate 2, and the support column 41 is used to support the welding mechanism 4 as a whole.

[0030] Please see Figure 1-4 In this embodiment of the utility model: the telescopic rod 44 passes through the support plate 42 and reaches the lower end of the support plate 42.

[0031] Please see Figure 5 In this embodiment of the utility model: the transmission mechanism 3 includes a drive motor 31, a threaded shaft 32, a limiting plate 33, a lead screw 34, and a moving plate 35. The drive motor 31 is connected to the threaded shaft 32 via a coupling. Two sets of limiting plates 33 are provided, arranged symmetrically on the left and right sides. The two sets of limiting plates 33 are fixedly connected to the top of the placement plate 2. The threaded shaft 32 passes through one set of limiting plates 33, and its end is connected to the other set of limiting plates 33. Two sets of lead screws 34 are provided between the two sets of limiting plates 33. The two sets of lead screws 34 are distributed on the left and right sides of the threaded shaft 32. The moving plate 35 is connected to the outer surface of the threaded shaft 32 and the two sets of lead screws 34. The transmission device is used to adjust the position of the welding operation.

[0032] Please see Figure 1-5 In this embodiment of the utility model: the top of the movable plate 35 is provided with a plurality of placement holes 351, which are used to place studs.

[0033] Please see Figure 1-5 In this embodiment of the utility model: the diameter of the outer sheath layer 45 is larger than the diameter of the placement hole 351.

[0034] Please see Figure 1-5 In this embodiment of the utility model: the length of the welding rod 46 and the welding head 47 is less than the length of the outer sheath layer 45. Since the length of the welding rod 46 and the welding head 47 is less than the length of the outer sheath layer 45, it means that if the bottom of the outer sheath layer 45 is in complete contact with the moving plate 35, and if the placement hole 351 on the moving plate 35 is not used to place the stud or the stud falls off, the welding head 47 will not contact the moving plate 35.

[0035] The working principle is as follows:

[0036] When using the device, the user first places the stud to be welded into the placement hole 351. Then, the drive motor 31 is started. The drive motor 31 moves the moving plate 35 to a position that matches the welding mechanism 4 by rotating the threaded shaft 32. At this time, the electric cylinder 43 is activated, which moves the telescopic rod 44 downward. The outer sheath 45 completely surrounds the stud placed in the placement hole 351. When the welding head 47 contacts the stud, the telescopic rod 44 stops moving downward, and the welding head 47 welds the stud. After one set of studs has been welded, the electric cylinder 43 is adjusted, which moves the telescopic rod 44 upward. The user then adjusts the drive motor 31 to move the next set of studs to be welded to the corresponding position. The above actions are repeated to continue welding.

[0037] Compared with the prior art, this utility model provides a welding device for stud processing, which has the following features:

[0038] Beneficial effects:

[0039] In this invention, a welding mechanism 4 is provided at the upper end of the placement plate 2. Through the cooperation of the telescopic rod 44 and the outer sheath layer 45, the outer sheath layer 45 can completely surround the threaded post placed in the placement hole 351 when the user is performing welding work, thereby enabling welding. The outer sheath layer 45 improves the safety of welding work. At the same time, since the lengths of the welding rod 46 and the welding head 47 are less than the length of the outer sheath layer 45, it means that even if the bottom of the outer sheath layer 45 is in complete contact with the moving plate 35, if the placement hole 351 on the moving plate 35 does not contain the threaded post or the threaded post falls off, the welding head 47 will not contact the moving plate 35 to form a welding circuit, reducing the risk and improving the safety of the device.
