Description

Technical Field

[0001] This invention relates to the field of stainless steel plate welding technology, specifically to a guiding docking and positioning mechanism and welding equipment for stainless steel plate welding. Background Technology

[0002] Stainless steel sheet is a versatile and durable material used in a wide range of applications, from kitchenware to construction projects. To fully utilize its properties, stainless steel sheets are often welded together. Stainless steel sheet welding is the process of joining two stainless steel sheets together using heat and pressure. The weld forms a strong, permanent bond between the metals, allowing them to function as a whole.

[0003] However, existing steel plate welding equipment requires welding both sides of the steel plate when welding thicker steel plates. This makes it inconvenient for operators to flip the steel plates, is laborious, and involves a large workload. Furthermore, it cannot weld two steel plates of different sizes, making it difficult to position and clamp the two plates. For irregularly shaped steel plates that require welding at special angles, it is also inconvenient to fix them. Therefore, it does not meet the current requirements. To address this, we propose a guiding docking and positioning mechanism and its welding equipment for welding stainless steel plates. Summary of the Invention

[0004] The purpose of this invention is to provide a guiding and positioning mechanism and welding equipment for welding stainless steel plates, so as to solve the problems mentioned in the background art. When welding thicker steel plates, existing steel plate welding equipment requires welding on both sides of the steel plate, which is inconvenient for operators to flip the steel plate, is laborious, and has a large workload. It also cannot weld two steel plates of different sizes, and it is inconvenient to position and clamp the two steel plates. For irregularly shaped steel plates that need to be welded at a special angle, it is inconvenient to fix them.

[0006] Preferably, the moving mechanism includes a threaded rod, the outer surface of which is fitted with a threaded plate, the upper end face of which is fixedly connected to the lower end face of the vertical plate, and a first motor for rotating the threaded rod is installed on both sides of the outer surface of the base plate.

[0007] Preferably, the clamping mechanism includes a horizontal plate, a groove is provided on one side of the front end face of the horizontal plate, an electric push rod is installed at the front and rear of the upper end face of the horizontal plate, a pressure plate is fixedly connected to the lower end face of the electric push rod, and a plurality of vacuum suction cups are evenly installed on the lower end face of the pressure plate.

[0008] Preferably, a vacuum pump is installed in the middle of the upper surface of the horizontal plate, and the vacuum pump is connected to the vacuum suction cup through a connecting pipe.

[0009] Preferably, the inner side of the rotating seat is provided with a motor cavity, and a second motor is installed inside the motor cavity. The output end of the second motor is fixedly connected to the outer surface of the cross plate through a coupling.

[0010] Preferably, the limiting mechanism includes a fixed shell, a movable plate is mounted on the inner side of the fixed shell by a spring, and a movable block is mounted on the upper end surface of the movable plate.

[0011] Preferably, a locking block is installed on one side of the outer surface of the movable block, the other side of the outer surface of the movable block is an arc surface, and an opening is provided on the upper end face of the fixed shell. The movable block passes through the opening, and the locking block can be locked into the inside of the opening.

[0012] Preferably, the outer surface of the fixed shell is fixedly connected to the inner wall of the shell, the front end face of the short shaft is fixedly connected to the rear end face of the rotating shaft through a connecting shaft, and the rear end face of the short shaft is rotatably connected to the inner wall of the shell through a bearing.

[0013] Preferably, a torsion spring is fitted on the outer surface of the short shaft, one end of the torsion spring is fixedly connected to the inner wall of the housing, the other end of the torsion spring is fixedly connected to the outer surface of the rotating disk, and the rear end face of the rocker arm is fixedly connected to the front end face of the rotating shaft through a horizontal axis.

[0014] Preferably, a welding device is characterized by including the guiding and positioning mechanism for welding stainless steel plates as described in any one of claims 1-9. Compared with the prior art, the beneficial effects of the present invention are: 1. This invention features a moving mechanism that allows adjustment of the positions of the two vertical plates by controlling the switch of the first motor. A clamping mechanism places the stainless steel plate to be welded inside the groove, ensuring the rear end face of the stainless steel plate is flush with the inner wall of the groove. Controlling the switch of the electric push rod causes the pressure plate to press down, bringing the vacuum suction cup into contact with the upper end face of the stainless steel plate. Turning on the vacuum pump performs vacuum treatment on the vacuum suction cup, improving the stability of the stainless steel plate's adsorption. A second motor drives the clamping mechanism to rotate, allowing the horizontal plate and stainless steel plate to be flipped. This invention can flip steel plates and position and clamp two steel plates of different sizes. 2. This invention, by incorporating a rotating disk, a limiting mechanism, a short shaft, and a torsion spring, allows for the adjustment and fixing of stainless steel plates at specific angles during welding. Rotating the rocker arm clockwise causes the rotating shaft to rotate, which in turn causes the short shaft to rotate clockwise. This causes the serrations that engage with the locking block to rotate clockwise, disengaging from the outer surface of the locking block. The arc-shaped end of the right-side serration contacts the arc surface, pressing the movable block downwards. Once the desired angle is reached, rotation stops, and the locking block is pushed upwards by the spring. Rotating the rocker arm counterclockwise allows the locking block to engage with an opening in one of the suitable serrations, limiting the rotation of the rotating disk. The torsion spring applies a continuous reverse torque to the short shaft, ensuring the locking block remains stable inside the opening and guaranteeing reliable locking. This invention allows for the adjustment and fixing of the horizontal angle of stainless steel plates, facilitating welding at specific angles. Attached Figure Description

[0020] The moving mechanism 7 includes a threaded rod 702, and a threaded plate 703 is fitted on the outer surface of the threaded rod 702. The upper end face of the threaded plate 703 is fixedly connected to the lower end face of the vertical plate 3. A first motor 701 for rotating the threaded rod 702 is installed on both sides of the outer surface of the base plate 1. The first motor 701 drives the threaded rod 702 to rotate. The threaded plate 703 can move left and right on the outer surface of the threaded rod 702, thereby driving the vertical plate 3 to move and adjusting the distance between the two clamping mechanisms 6.

[0021] The clamping mechanism 6 includes a horizontal plate 601. A groove 606 is provided on one side of the front end face of the horizontal plate 601. An electric push rod 603 is installed at the front and rear of the upper end face of the horizontal plate 601. A pressure plate 604 is fixedly connected to the lower end face of the electric push rod 603. Multiple vacuum suction cups 605 are evenly installed on the lower end face of the pressure plate 604. When the electric push rod 603 is working, it can drive the pressure plate 604 to press down.

[0022] A vacuum pump 602 is installed in the middle of the upper end face of the horizontal plate 601. The vacuum pump 602 is connected to the vacuum suction cup 605 through a connecting pipe. When the vacuum pump 602 is working, it can perform vacuum treatment on the vacuum suction cup 605.

[0023] The inner side of the rotating base 5 is provided with a motor cavity 10, and a second motor 9 is installed inside the motor cavity 10. The output end of the second motor 9 is fixedly connected to the outer surface of the horizontal plate 601 through a coupling. The operation of the second motor 9 can drive the horizontal plate 601 to rotate.

[0024] The limiting mechanism 13 includes a fixed shell 1301. A movable plate 1303 is installed on the inner side of the fixed shell 1301 via a spring 1302. A movable block 1305 is installed on the upper end face of the movable plate 1303. A locking block 1306 is installed on one side of the outer surface of the movable block 1305. The other side of the outer surface of the movable block 1305 is an arc surface 1307. An opening 1304 is provided on the upper end face of the fixed shell 1301. The movable block 1305 passes through the opening 1304. The locking block 1306 can be locked into the inner side of the opening 17. When the short shaft 14 rotates clockwise, the saw teeth 16 that are locked with the locking block 1306 rotate clockwise and leave the outer surface of the locking block 1306. The arc end of the right saw teeth 16 contacts the arc surface 1307, pressing the movable block 1305 downward.

[0025] The outer surface of the fixed shell 1301 is fixedly connected to the inner wall of the shell 11. The front end face of the short shaft 14 is fixedly connected to the rear end face of the rotating shaft 8 through a connecting shaft. The rear end face of the short shaft 14 is rotatably connected to the inner wall of the shell 11 through a bearing, thereby improving the stability of the fixed shell 1301 and the rotation stability of the short shaft 14.

[0026] A torsion spring 15 is fitted on the outer surface of the short shaft 14. One end of the torsion spring 15 is fixedly connected to the inner wall of the housing 11, and the other end of the torsion spring 15 is fixedly connected to the outer surface of the rotating disk 12. The rear end face of the rocker arm 18 is fixedly connected to the front end face of the rotating shaft 8 through a horizontal axis. The torsion spring 15 applies a counterclockwise elastic force to the short shaft to ensure that the locking block 1306 remains stable inside the opening 17. The rotating shaft 8 can be rotated by rotating the rocker arm 18.

[0027] A welding device, characterized in that it includes a guide docking and positioning mechanism for welding stainless steel plates as described in any one of claims 1-9.

[0028] The guide and positioning mechanism for stainless steel plate welding is used by first connecting the power supply. The moving mechanism 7, controlled by the first motor 701, adjusts the positions of the two vertical plates 3. The clamping mechanism 6 places the stainless steel plate to be welded inside the groove 606, ensuring the rear end face of the plate is flush with the inner wall of the groove. The electric push rod 603 then presses down the pressure plate 604, causing the vacuum suction cup 605 to contact the upper surface of the stainless steel plate. The vacuum pump 602 is then turned on to vacuum the suction cup 605, improving the stability of the stainless steel plate's adhesion. The second motor 9 rotates the clamping mechanism 6, allowing the horizontal plate 601 to be flipped, thus flipping the stainless steel plate. When welding at a specific angle, the rocker arm 18 can be turned clockwise, causing the rotating shaft 8 to rotate. When the short shaft 14 rotates clockwise, the serration 16 that engages with the locking block 1306 rotates clockwise, leaving the outer surface of the locking block 1306, and the arc end of the right serration 16 contacts the arc surface 1307, pressing the movable block 1305 downward. When the rotation reaches a suitable angle, the rotation stops, and the locking block 1306 is pushed upward under the action of the spring 1302. Then, the rocker arm 18 is rotated counterclockwise, so that the locking block 1306 engages in the opening 17 on the surface of one of the suitable serrations 16, limiting the rotation disk 12. Furthermore, through the provision of a torsion spring 15, the torsion spring 15 applies a counterclockwise elastic force to the short shaft 14, ensuring that the locking block 1306 remains stable inside the opening and ensuring reliable locking. This invention can flip steel plates, position and clamp two steel plates of different sizes, and adjust and fix the horizontal angle of stainless steel plates, thereby facilitating welding of stainless steel plates at special angles.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
