Description

Technical Field

[0001] This utility model relates to the field of compressor welding technology, specifically a ring welding machine for welding upper and lower covers. Background Technology

[0002] A ring welding machine is a device specifically designed for welding circumferential seams. It achieves continuous and uniform welding through the circular motion of the welding torch and is suitable for connecting circumferential structures such as pipes, flanges, and cylinders. In compressor cylinders, the upper and lower covers of the cylinder body need to be sealed by welding, so a ring welding machine is required to weld the upper and lower covers of the cylinder body.

[0003] For example, patent CN209698351U discloses a welding mechanism for the upper cover of a refrigerator compressor, including an upper cover feeding device and a parts horizontal conveying device that causes a first electromagnet to reciprocate from the feeding position of the parts feeding device to the position below the parts mounting cavity. This can improve welding efficiency, ensure precise positioning during welding, achieve high welding quality, and is simple and convenient to operate, saving labor and eliminating the need for manual welding. Moreover, the turntable improves work efficiency, ensures precise positioning during welding, achieves high welding quality, and is simple and convenient to operate, saving labor. The welding column has a cooling function and a long service life. However, in the above case, some compressor cylinders have upper and lower covers, such as compressors that need to be used in a high-sealing environment. When welding the upper and lower covers, the cylinder body needs to be manually rotated or reversed to perform the weld, which reduces the overall work efficiency. Furthermore, the positioning deviation during manual rotation may lead to inconsistent welding quality of the upper and lower covers.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing ring welding machine used for welding the upper and lower covers. Utility Model Content

[0005] The purpose of this utility model is to provide a ring welding machine for welding upper and lower covers, so as to solve the problem mentioned in the background art that, since the compressor cylinder has an upper cover and a lower cover, the above case requires manual rotation or reversal of the cylinder body to weld the upper and lower covers, which reduces the overall work efficiency and may also lead to inconsistent welding quality of the upper and lower covers due to positioning deviation during manual flipping.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ring welding machine for welding upper and lower covers, comprising a worktable, a movable seat slidably connected to one side of the worktable, a collection box provided at the bottom of the worktable, and a clamping seat rotatably connected to the top of the worktable; a drive module is installed on one side of the movable seat, and a welding gun is provided on the other side of the movable seat; the clamping seat is provided with a clamping mechanism for clamping the cylinder body.

[0007] Furthermore, the clamping mechanism includes four rotating disks, which are rotatably connected to both ends of the inner wall of the clamping seat. The two rotating disks are provided with meshing teeth on the side that is close to each other. A clamping plate is installed on one side of the rotating disk, and a fixing column is fixedly connected between the two rotating disks on the same side.

[0008] Furthermore, a drive motor is installed inside the clamping seat, a fixed cylinder is installed at the output end of the drive motor, a quadrangular prism is slidably connected inside the fixed cylinder, an electric push rod is installed inside the clamping seat, and the output end of the electric push rod is rotatably connected to the quadrangular prism through a support plate.

[0009] Furthermore, a first bevel gear is rotatably connected to the top of the clamping seat. The interior of the first bevel gear is in movable contact with the top of the quadrangular prism. A second bevel gear is meshed with one side of the first bevel gear. The second bevel gear is rotatably connected to the top of the clamping seat via a transmission shaft. A spur gear is fixedly connected to one side of the transmission shaft on the second bevel gear and the outer wall of the fixed column. The two spur gears mesh with each other.

[0010] Furthermore, one side of the movable base is provided with an adjustment mechanism for adjusting the position of the welding torch. The adjustment mechanism includes a fixed rod, which is fixedly connected to the output end of the drive module. A movable rod is slidably connected inside the fixed rod. Both the movable rod and the fixed rod have threaded holes inside, and a threaded rod is installed inside the threaded holes. One side of the movable rod is fixedly connected to the welding torch.

[0011] Furthermore, an electric telescopic rod is installed inside the workbench, and a slider is fixedly connected to the output end of the electric telescopic rod. The top of the slider is fixedly connected to a movable seat, and a scraper is installed on one side of the bottom of the slider. A waste trough is opened inside the workbench, and the slider and scraper are slidably connected inside the workbench.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This ring welding machine for welding upper and lower covers uses a drive motor to drive the linkage between the fixed cylinder and the four-sided prism, and with the lifting control of the electric push rod, it realizes the 180-degree rotation function of the clamping seat. When the four-sided prism moves down and meshes with the bevel gear, the spur gear drives the rotating disk to move in opposite directions, completing the clamping and fixing of the cylinder body. When separating, it directly drives the clamping seat to rotate. After the upper cover ring welding is completed, the lower cover can be connected with the welding gun by rotating the clamping seat, thus effectively performing ring welding on the upper and lower covers of the cylinder body.

[0014] Furthermore, the moving rod and the fixed rod are height-adjustable through the cooperation of the threaded hole and the threaded rod. Combined with the drive module to drive the fixed rod to rotate, the welding gun can be positioned up and down and can also move in a circle to complete the ring welding. It can perform ring welds on the upper and lower covers according to the needs of different cylinder bodies.

[0015] Furthermore, when the electric telescopic rod pushes the slider to move, it not only positions the welding torch but also scrapes the waste into the collection box simultaneously through the scraper. This binds the welding displacement with the waste cleaning action, reduces downtime for cleaning, realizes continuous operation of welding and waste disposal, and improves overall production efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides the following technical solution: a ring welding machine for welding upper and lower covers, including a workbench 1, a movable seat 2 slidably connected to one side of the workbench 1, a collection box 3 provided at the bottom of the workbench 1, and a clamping seat 6 rotatably connected to the top of the workbench 1; a drive module 4 is installed on one side of the movable seat 2, and a welding torch 5 is provided on the other side of the movable seat 2; a clamping mechanism for clamping cylinder bodies is provided on the clamping seat 6; the clamping mechanism includes four rotating disks 8, the rotating disks 8 are rotatably connected to the two ends of the inner wall of the clamping seat 6, meshing teeth are provided on the side of two rotating disks 8 that are close to each other, a clamping plate 7 is installed on one side of the rotating disks 8, and a fixing column 9 is fixedly connected between two rotating disks 8 on the same side; the clamping seat 6 An internal drive motor 10 is installed, and a fixed cylinder 11 is installed at the output end of the drive motor 10. A quadrangular prism 12 is slidably connected inside the fixed cylinder 11. An electric push rod 16 is installed inside the clamping seat 6. The output end of the electric push rod 16 is rotatably connected to the quadrangular prism 12 through a support plate. A first bevel gear 13 is rotatably connected to the top of the clamping seat 6. The interior of the first bevel gear 13 is in movable contact with the top of the quadrangular prism 12. A second bevel gear 14 is meshed with one side of the first bevel gear 13. The second bevel gear 14 is rotatably connected to the top of the clamping seat 6 through a transmission shaft. A spur gear 15 is fixedly connected to one side of the transmission shaft on the second bevel gear 14 and the outer wall of the fixed column 9. The two spur gears 15 mesh with each other.

[0025] When welding is required on the upper and lower covers of the cylinder block, such as Figure 1 and Figure 2 As shown, by starting the drive motor 10, its output end drives the fixed cylinder 11 to rotate, as... Figure 3 and Figure 5 As shown, since a quadrangular prism 12 is slidably connected inside the fixed cylinder 11, the rotation of the fixed cylinder 11 will drive the quadrangular prism 12 to rotate, as... Figure 3 and Figure 5 As shown, when it is necessary to rotate the clamping seat 6, the electric push rod 16 is activated. At this time, the output end of the electric push rod 16 pushes the quadrangular prism 12 to slide up and down inside the fixed cylinder 11 through the support plate, so that the quadrangular prism 12 moves away from the first bevel gear 13. Then the drive motor 10 is activated. At this time, the drive motor 10 drives the fixed cylinder 11 and the quadrangular prism 12 to rotate. The quadrangular prism 12 drives the clamping seat 6 to rotate, so that the clamping seat 6 can rotate 180 degrees, flipping the cylinder body to achieve welding of the upper or lower cover of the cylinder body. Figure 3 and Figure 5As shown, when the cylinder body needs to be clamped and fixed, the electric push rod 16 rises, causing the quadrangular prism 12 to rise, thereby making the quadrangular prism 12 abut against the first bevel gear 13. At this time, the rotation of the quadrangular prism 12 will drive the first bevel gear 13 to rotate, as shown. Figure 5 As shown, since the first bevel gear 13 and the second bevel gear 14 mesh with each other, the rotation of the first bevel gear 13 will cause the second bevel gear 14 to rotate, as... Figure 3 and Figure 5 As shown, since spur gears 15 are fixedly connected to one side of the transmission shaft on the second bevel gear 14 and the outer wall of the fixed column 9, and the two spur gears 15 mesh with each other, the rotation of the second bevel gear 14 drives the fixed column 9 to rotate through the transmission of the spur gears 15, as shown. Figure 3 and Figure 5 As shown, since the fixed column 9 is connected to the two rotating disks 8 on the same side, the rotation of the fixed column 9 causes the rotating disks 8 to rotate. Since the two rotating disks 8 are provided with meshing teeth on the side that is close to each other, the two rotating disks 8 on the same side will rotate towards or away from each other. A clamping plate 7 is installed on one side of the rotating disk 8. The rotation of the rotating disk 8 causes the clamping plate 7 to move in a straight line towards or away from each other, thereby realizing the clamping or releasing operation of the cylinder body.

[0026] Example 2: Please refer to Figure 2 , Figure 4 and Figure 6 Based on Embodiment 1, an adjustment mechanism is also disclosed, the specific structure of which is as follows:

[0027] The adjustment mechanism includes a fixed rod 20, which is fixedly connected to the output end of the drive module 4. A movable rod 21 is slidably connected inside the fixed rod 20. Both the movable rod 21 and the fixed rod 20 have threaded holes 23 inside. A threaded rod 22 is installed inside the threaded holes 23. One side of the movable rod 21 is fixedly connected to the welding gun 5. An electric telescopic rod 18 is installed inside the worktable 1. A slider 17 is fixedly connected to the output end of the electric telescopic rod 18. The top of the slider 17 is fixedly connected to the movable seat 2. A scraper 19 is installed on one side of the bottom of the slider 17. A waste trough is opened inside the worktable 1. The slider 17 and the scraper 19 are slidably connected inside the worktable 1.

[0028] When it is necessary to adjust the position of welding torch 5, such as Figure 2 and Figure 4As shown, since both the movable rod 21 and the fixed rod 20 have threaded holes 23 inside, and the threaded rod 22 is installed inside the threaded hole 23, the movable rod 21 can slide up and down, allowing it to slide inside the fixed rod 20. After the movable rod 21 is slid to a suitable position, the relative position between the movable rod 21 and the fixed rod 20 can be fixed by fixing the threaded rod 22 inside the threaded hole 23 inside both the movable rod 21 and the fixed rod 20. Figure 4 and Figure 6 As shown, the drive module 4 is then activated. Once activated, its output drives the fixed rod 20 to rotate, which in turn drives the moving rod 21 to rotate, thus causing the welding torch 5 to rotate in a circular motion. This allows for the annular welding of the upper and lower covers of the cylinder body. During the welding process, some waste is generated, such as… Figure 4 and Figure 6 As shown, when cleaning up waste, the electric telescopic rod 18 inside the workbench 1 can be activated. After the electric telescopic rod 18 is activated, its output end pushes the slider 17 to slide inside the workbench 1. Since the top of the slider 17 is fixedly connected to the moving seat 2, the sliding of the slider 17 drives the moving seat 2 to move, so that the welding torch 5 reaches the welding position. At the same time, the scraper 19 installed on one side of the bottom of the slider 17 slides in the waste trough inside the workbench 1 as the slider 17 slides, scraping the waste generated during the welding process into the collection box 3, thereby realizing the collection and cleaning of waste.
