Description

Technical Field

[0001] This utility model relates to the field of sheet metal welding, and in particular to a sheet metal welding connection structure. Background Technology

[0002] Sheet metal parts are thin sheet metal parts, which are parts that can be processed by stamping, bending, stretching and other means. A general definition is that the thickness of the parts does not change during the processing, and they are often assembled into accessories by welding.

[0003] Chinese Patent No. CN218426595U discloses a sheet metal welding connection structure, including a base frame and a first fixed frame. A slide rail is fixedly installed on the top of the base frame, and a threaded rod is threadedly connected to the inside of the first fixed frame. In this solution, two sheet metal parts are respectively installed on the upper ends of the first fixed frame and the second fixed frame. Rotating the rotating block drives the threaded rod to rotate, controlling the first fixed frame to move on the upper end of the slide rail, so as to fix the two sheet metal parts, making it convenient for the user to weld the two sheet metal parts, making it easier for the user to position the sheet metal parts, and making it more convenient when welding multiple sheet metal parts. The operation is simple.

[0004] However, the aforementioned patent requires manual rotation for the connection and positioning of sheet metal parts, making it difficult to automatically position and connect them, which reduces the connection and positioning speed during sheet metal welding. To address this issue, we propose a sheet metal welding connection structure. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through the setting of the positioning seat, can initially position the sheet metal parts. By starting the electric cylinder and cooperating with the sliding plate and the moving positioning plate, the moving positioning plate can be moved to contact the sheet metal parts, realizing automatic positioning and clamping of the sheet metal parts without manual operation.

[0023] Please see Figures 1-4In this utility model, a sheet metal welding connection structure includes a transmission mechanism 1. Two movable plates 2 are provided on one side of the transmission mechanism 1. Positioning seats 3 are installed on the upper surface of each of the two movable plates 2. Fixing blocks 4 are fixedly connected to the bottom surface of each of the two movable plates 2. Electric cylinders 5 are installed on one side of each of the two fixing blocks 4. The electric cylinder 5 is an electric drive device that converts the rotational motion of an electric motor into the linear reciprocating motion of the electric cylinder 5. It can be used as an execution machine in various simple or complex processes to achieve remote control, centralized control or automatic control. Sliding plates 6 are installed on the telescopic ends of each of the two electric cylinders 5. Moving positioning plates 8 are installed on one side of each of the two sliding plates 6. Limiting slide seats 9 are fixedly connected to the bottom surface of the transmission mechanism 1. Limiting sliders 10 are fixedly connected to one side of each of the two fixing blocks 4. The outer surfaces of the two limiting sliders 10 are slidably connected to the inner wall of the limiting slide seat 9. By sliding the limiting sliders 10 on the inner wall of the limiting slide seat 9, the movement of the movable plates 2 is limited and guided, ensuring the smooth movement of the movable plates 2.

[0024] In a further embodiment, the transmission mechanism 1 includes a transmission base 101. Two transmission blocks 104 are slidably connected to the inner wall of the transmission base 101. A dual-head motor 102 is mounted on the inner wall of the transmission base 101. The dual-head motor 102 is a dual-head DC motor with two rotors and one stator. The two rotors are located at the front and rear of the motor, respectively. When current passes through the motor, both rotors begin to rotate. A transmission screw 103 is mounted on each of the two output ends of the dual-head motor 102. The outer surfaces of the two transmission screws 103 are threadedly connected to the inner walls of the two transmission blocks 104, respectively. One side of each of the two transmission blocks 104 is connected to one side of each of the two moving plates 2. Two bearings are mounted on the inner wall of the transmission base 101. The bearing housing 105 is a support for mounting the inner ring of the bearing. The inner rings of the two bearing housings 105 are respectively connected to the inner rings of the two transmission screws 103. Through the operation of the double-head motor 102, the two transmission screws 103 can be driven to connect with the two transmission blocks 104 respectively, which can make the two transmission blocks 104 move towards or away from each other along the inner wall of the transmission seat 101. At the same time, it will also drive the moving plate 2 and the positioned sheet metal parts to move, which can adjust the distance between the two sheet metal parts to be welded, so that they can reach a suitable welding position. The bearing housing 105 can provide support and rotation assistance for the transmission screws 103, making the rotation of the transmission screws 103 more stable.

[0025] In a further embodiment, a sliding seat 11 is fixedly connected to the bottom surface of each of the two fixed blocks 4, and a sliding block 12 is slidably connected to the inner wall of each of the two sliding seats 11. The upper surfaces of the two sliding blocks 12 are respectively connected to the bottom surfaces of the two sliding plates 6. By sliding the sliding blocks 12 on the inner wall of the sliding seat 11, the movement of the sliding plate 6 can be assisted, making its movement more stable. A sliding hole 7 is provided on the upper surface of each of the two moving plates 2, and the outer surfaces of the two sliding plates 6 are respectively slidably connected to the inner walls of the two sliding holes 7. By setting the sliding holes 7, the moving plates 2 can slide smoothly inside them. The bottom surface of the movable seat 11 is equipped with movable pulleys 13, and the upper surface of the transmission mechanism 1 is equipped with a controller 15. The bottom surface of the transmission mechanism 1 is fixedly connected with two support seats 14. The movable pulleys 13 can support the sliding seat 11 and the movable plate 2, which will make the movable plate 2 more stable when supporting the sheet metal parts. The two support seats 14 can provide stable support for the bottom of the transmission mechanism 1. The controller 15 can start and stop the dual-head motor 102 and control the extension and retraction of the electric cylinder 5, realizing the automated control of the sheet metal welding connection structure.

[0026] The working principle of this utility model is as follows: First, the operator places the sheet metal part to be welded on top of the two movable plates 2, and makes one side of the sheet metal part contact the positioning seat 3. The positioning seat 3 can initially position the sheet metal part to be welded. Then, the electric cylinder 5 is started to retract, which can drive the sliding plate 6 and the movable positioning plate 8 to move until the movable positioning plate 8 contacts the sheet metal part to be welded, which can further position and clamp the sheet metal part. Then, the transmission mechanism 1 is started to work, which can drive the two movable plates 2 and the positioned sheet metal part to move closer to each other until the two sheet metal parts contact each other, thereby completing the connection and positioning of the two sheet metal parts, which facilitates subsequent welding.
