Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a production line type multi-station sealing welding assembly. Background Technology

[0002] In modern industrial manufacturing, welding, as a key joining process, plays a decisive role in the quality and performance of many products. In the early welding production process, especially when it comes to the manufacturing of products that require sealing welding, traditional manual welding or relatively simple semi-automatic welding methods were mostly used. This method involves high labor intensity for workers, and long-term welding operations can easily lead to fatigue, which in turn affects the stability of welding quality. Furthermore, the connection between each welding step is not tight and efficient enough, resulting in low overall production efficiency. However, with the advancement of technology, assembly line-type multi-station sealing welding components have emerged.

[0003] Existing welding equipment typically involves workers placing the workpiece to be welded under the welding head, then activating an electric push rod to bring the welding head into contact with the workpiece. The welding operation is then performed by the operator manually setting basic parameters such as welding time and current intensity.

[0004] In the prior art, when welding some workpieces, the material in the welding area heats up and melts rapidly, and then cools and solidifies. When the material cools and solidifies, different parts will produce different degrees of elastic deformation due to the difference in thermal stress. This will cause the workpiece to become unbalanced, and then cause the workpiece to shake during the welding process, resulting in a decrease in welding quality. Therefore, in order to address the above shortcomings, a production line type multi-station sealing welding assembly is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-station sealing welding assembly for assembly lines. This assembly aims to improve the problem of reduced welding quality caused by object shaking during the welding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station sealed welding assembly for assembly lines, comprising a housing, a working plate fixedly connected to the top of the housing, a transmission groove formed at the top of the working plate, a welding assembly for support fixedly connected to the top of the working plate, an electric push rod fixedly connected to the bottom of the housing, a force plate fixedly connected to the driving end of the electric push rod, two pressing blocks fixedly connected to the top of the force plate, two receiving holes formed inside the top of the working plate, two sliding rods slidably connected to the inner wall of the top of the working plate, a sliding disc fixedly connected to the outside of the sliding rods, a telescopic spring sleeved on the outside of the sliding rods, clamping plates fixedly connected to the adjacent sides of the two sliding rods, and a support assembly for bearing load fixedly connected to the bottom of the housing.

[0007] Furthermore, a feeding trough is provided on the top left side of the working plate, two support plates are fixedly connected to the top rear side of the working plate, and a fixing rod is fixedly connected to the adjacent side of the two support plates. A feeding block is fixedly connected to the top front side of the working plate, an electric push rod II is fixedly connected to the right end of the box, a connecting block is fixedly connected to the driving end of the electric push rod II, a connecting rod is rotatably connected to the right side of the connecting block, a connecting block is fixedly connected to the outer top of the connecting rod, a sliding block is rotatably connected to the left side of the connecting block, a push plate is fixedly connected to the left side of the sliding block, and a support rod is fixedly connected to the right top of the box.

[0008] Furthermore, the welding assembly includes a support frame, the bottom end of which is fixedly connected to the top end of the work plate, and a linear motor is fixedly connected to the top end of the support frame, with a welding head fixedly connected to the drive end of the linear motor.

[0009] Furthermore, a sliding hole is provided inside the top of the box body, the outside of the force plate is slidably connected to the inside of the sliding hole, and the outside of the extrusion block is slidably connected to the inside of the sliding hole.

[0010] Furthermore, the curved side of the extrusion block contacts the curved side driven by the sliding rod, and the outside of the sliding disk is slidably connected inside the receiving hole.

[0011] Furthermore, one end of the telescopic spring is fixedly connected to the inside of the receiving hole, and the other end of the telescopic spring is fixedly connected to one side of the sliding disc.

[0012] Furthermore, the support assembly includes multiple support legs, the top ends of which are fixedly connected to the bottom end of the housing, and the bottom ends of the support legs are fixedly connected to a pad.

[0013] Furthermore, the outer middle end of the connecting rod is rotated to connect to the inside of the right side of the support rod, the outer side of the sliding block is slidably connected to the inside of the transmission groove, the outer side of the push plate is slidably connected to the inside of the transmission groove, and the inner side of the push plate is slidably connected to the outside of the fixed rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by activating the electric push rod, the force plate is driven to make the arc of the extrusion block contact the arc of the sliding rod, thereby extruding the sliding rod. This not only causes the sliding plate to extrude the telescopic spring, but also causes the clamping plate to clamp the workpiece, ensuring that the workpiece maintains a stable position throughout the welding process. This prevents the weld from deviating from the correct position due to workpiece displacement, thereby improving the welding accuracy and quality.

[0016] 2. In this utility model, after welding is completed, the electric push rod is activated, which causes the connecting block to drive the connecting rod to push the sliding block and push the push plate to push the workpiece, thus completing the pushing of the workpiece. This facilitates the loading and unloading of the workpiece, enabling the entire production process to proceed continuously, reducing downtime and waiting time in the production process, and improving the operating efficiency of the entire production line.

[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] Reference Figures 1 to 3 This utility model provides an embodiment of a multi-station sealed welding assembly for assembly lines, including a housing 1. The housing 1 serves as the basic outer shell structure of the entire device, protecting the internal components and providing an overall support frame. A work plate 2 is fixedly connected to the top of the housing 1. A transmission groove 3 is provided at the top of the work plate 2. A welding assembly for support is fixedly connected to the top of the work plate 2. A linear motor 5 is fixedly connected to the top of the support frame 4. A welding head 6 is firmly fixedly connected to the drive end of the linear motor 5. The welding head 6 can move to a designated welding position for welding operations under the drive of the linear motor 5. An electric push rod 7 is fixedly connected to the bottom of the interior of the housing 1. A force plate 8 is fixedly connected to the drive end of the electric push rod 7. Two extrusion blocks 9 are fixedly connected to the top of the force plate 8. A sliding hole 10 is provided inside the top of the housing 1. The outside of the force plate 8 can slide smoothly up and down inside the sliding hole 10. The outside of the extrusion blocks 9 can also slide inside the sliding hole 10. Two receiving holes 11 are provided inside the top of the work plate 2.

[0025] Two sliding rods 12 are slidably connected to the inner wall of the top of the working plate 2. A sliding disk 13 is fixedly connected to the outside of the sliding rods 12. The curved side of the extrusion block 9 contacts the curved side of the sliding rod 12. This curved design allows the extrusion block 9 to effectively extrude the sliding rod 12 when it moves up and down. The outside of the sliding disk 13 can slide smoothly inside the receiving hole 11. A telescopic spring 14 is sleeved on the outside of the sliding rod 12. One end of the telescopic spring 14 is fixedly connected to the inside of the receiving hole 11, and the other end is fixedly connected to the side of the sliding disk 13. When the sliding disk 13 moves, the telescopic spring 14 will be compressed accordingly. Clamping plates 15 are fixedly connected to the adjacent sides of the two sliding rods 12. The clamping plates 15 can move closer to each other under the action of the sliding rods 12, thereby realizing the clamping and releasing action of the workpiece. The bottom of the housing 1 is fixedly connected to a support assembly for bearing load. The support assembly includes multiple support legs 16. The top ends of the multiple support legs 16 are fixedly connected to the bottom of the housing 1. The bottom ends of the support legs 16 are fixedly connected to a pad 17. The pad 17 can increase the contact area between the support legs 16 and the ground, thereby improving the stability of the entire device.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The top left side of the work plate 2 has a feeding groove 18, which provides an outlet channel for the workpiece after welding. Two support plates 19 are fixedly connected to the rear top of the work plate 2. The two support plates 19 are parallel to each other and spaced a certain distance apart. A fixing rod 20 is fixedly connected to the adjacent side of the two support plates 19, which provides guidance and support for the movement of subsequent components. A feeding block 21 is fixedly connected to the front top of the work plate 2. The feeding block 21 has an arc-shaped groove inside. The inclined angle allows the workpiece to fall naturally. When pushing a workpiece for clamping and welding, the sliding block 26 blocks the feeding hole of the feeding block 21, ensuring that only one workpiece can be fed at a time. Electric push rod 22 is fixedly connected to the right end of housing 1. Electric push rod 22 is another key power component. Its drive end is fixedly connected to connecting block 23. Connecting block 23 can move left and right under the drive of electric push rod 22. Connecting rod 24 is rotatably connected inside the right side of connecting block 23. Connecting rod 24 can rotate around the connection point with connecting block 23.

[0027] A connecting block 25 is fixedly connected to the outer top of the connecting rod 24. The connecting block 25 is tightly connected to the connecting rod 24. A sliding block 26 is rotatably connected to the left end of the connecting block 25. The outer side of the sliding block 26 can slide left and right inside the transmission groove 3. A push plate 27 is fixedly connected to the left end of the sliding block 26. The push plate 27 is integrally formed with the sliding block 26. The outer side of the push plate 27 can slide inside the transmission groove 3, and the inner side of the push plate 27 can slide outside the fixed rod 20. A support rod 28 is fixedly connected to the right top of the housing 1. The outer middle end of the connecting rod 24 is rotatably connected to the right inner side of the support rod 28. The support rod 28 provides a stable support point for the rotation of the connecting rod 24, enabling the entire loading, unloading and welding process to be carried out.

[0028] Working principle: First, the workpiece is placed in the loading block 21, which has an arc-shaped groove inside. The workpiece falls naturally using the tilt angle. When the electric push rod 22 is activated, its drive end drives the connecting block 23 to move to the right. The connecting block 23 drives the connecting rod 24, which is rotatably connected to it, to rotate around the support rod 28. The rotation of the connecting rod 24 causes the connecting block 25 to move to the left. The connecting block 25 drives the sliding block 26, which is rotatably connected to it, to slide to the left inside the transmission groove 3. The sliding block 26 drives the push plate 27 to slide to the left inside the transmission groove 3. The push plate 27 slides along the outside of the fixed rod 20, pushing a workpiece from the loading block 21 to a predetermined position on the working plate 2. At this time, the sliding block 26 will block the unloading hole of the loading block 21 to ensure that only one workpiece is loaded at a time.

[0029] After the workpiece is in place, the electric push rod 7 is activated. The drive end of the electric push rod 7 pushes the force plate 8 upward. The force plate 8 slides inside the sliding hole 10. The force plate 8 drives the extrusion block 9 to slide upward inside the sliding hole 10. The arc-shaped surface of the extrusion block 9 contacts the arc-shaped surface of the sliding rod 12 and extrudes the sliding rod 12. The sliding rod 12 slides on the inner wall of the top of the working plate 2 and drives the sliding disk 13 to slide inside the receiving hole 11. The sliding disk 13 extrudes the telescopic spring 14. At the same time, the two sliding rods 12 drive the clamping plate 15 to move closer to each other to clamp the workpiece, ensuring that the workpiece maintains a stable position throughout the welding process and avoiding the weld from deviating from the correct position due to workpiece displacement, thereby improving welding accuracy and quality. After the workpiece is clamped and positioned, the linear motor 5 is activated. The drive end of the linear motor 5 drives the welding head 6 to move to the welding position to perform the sealing welding operation.

[0030] After welding is completed, the electric push rod 7 is operated in the opposite direction, causing the force plate 8 to move the pressing block 9 downward. The force on the sliding rod 12 disappears, and the telescopic spring 14 generates a rebound force to push the sliding disk 13, thereby causing the clamping plate 15 to reset and release the workpiece. Then, the electric push rod 22 is started again, driving the connecting block 23 to move to the left, causing the connecting rod 24 to rotate in the opposite direction around the support rod 28, causing the connecting block 25 to move to the right. The connecting block 25 drives the sliding block 26 to slide to the right inside the transmission groove 3, and the sliding block 26 drives the push plate 27 to slide to the right inside the transmission groove 3, pushing the welded workpiece to the unloading groove 18 to complete the unloading. This allows the entire production process to proceed continuously, reducing downtime and waiting time during production and improving the operating efficiency of the production line.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
