Description

Technical Field

[0001] This utility model belongs to the technical field of guide rail suction cup equipment, specifically relating to a double-row guide rail suction cup equipment. Background Technology

[0002] In the general welding manufacturing of pressure pipelines, heat pipelines, pressure vessels, and steel structures, manual arc welding or semi-automatic welding is often used. This method is labor-intensive, has low production efficiency, and results in poor weld quality, large deformation, and welding defects such as cracks and lack of fusion. Adopting automatic welding technology is an effective way to improve welding efficiency, weld quality, reduce welder labor intensity and production costs, and represents a future direction for welding technology development. Therefore, it is necessary to develop automatic welding technology.

[0003] According to patent number CN201721593931.2, a vacuum adsorption type flexible guide rail for an automatic welding machine includes a guide rail, a suction cup frame, a support block, and a suction cup pneumatic control system. The guide rail is a strip structure, and multiple suction cup frames are evenly distributed on the bottom surface of the guide rail. The suction cup frames are connected to the guide rail through the support block, and the suction cup pneumatic control system is connected to the suction cup frames.

[0004] The above solution still has certain defects in actual use. Since the same set of suction cups is connected to the guide rail through the crossbeam and support block, although it can adsorb non-planar tools in the direction of the guide rail, in the process of use, if the workpiece has a non-planar structure such as a stepped or inclined surface when the two suction cups in the same set adsorb the workpiece, the suction cups will not be able to adsorb the workpiece stably, which will seriously affect the stability of the workpiece after adsorption. Therefore, we propose a double-row guide rail suction cup device. Utility Model Content

[0005] The purpose of this invention is to provide a double-row guide rail suction cup device to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-row guide rail suction cup device, comprising a flexible guide rail, a movable frame, and a support sleeve. Multiple first movable seats are fixedly connected to the bottom of the flexible guide rail. The bottom end of each first movable seat is movably connected to the movable frame. The bottom of the movable frame is movably connected to a second movable seat. A suction cup is fixedly installed at the bottom of the second movable seat. Connecting plates are fixedly welded to both ends of the movable frame. The connecting plates have a semi-circular plate structure. The connecting plates at both ends of the movable frame extend into the interior of the first and second movable seats respectively and are movably connected to them via pins. A support sleeve is also provided between the first movable seat and the movable frame. The top end of the support sleeve is movably connected to the first movable seat via a movable connecting seat. A telescopic rod is slidably arranged inside the support sleeve. A resistance spring is provided at one end of the telescopic rod extending into the support sleeve. One end of the telescopic rod is movably connected to the movable frame via the movable connecting seat.

[0007] Preferably, the support sleeve has limit grooves on both sides inside, and the telescopic rod has limit blocks on both sides at the top end. The limit blocks extend into the limit grooves and are slidably connected to their inner walls.

[0008] Preferably, a vacuum generator is provided in the middle of the two suction cups in the same group at the bottom of the flexible guide rail, and the vacuum generator is fixedly installed at the bottom of the flexible guide rail.

[0009] Preferably, the bottom of the flexible guide rail is also provided with a pipe, which is connected in parallel with the vacuum generator and the suction cup.

[0010] Preferably, a manual master valve is provided at one end of the pipeline, and the end of the pipeline with the manual master valve is connected to the gas source.

[0011] Preferably, a vacuum release valve is provided on one side of the top of the suction cup.

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

[0013] 1. By utilizing the movable frame and its connecting plates at both ends, and with the help of pins, the two ends are movably connected to the first movable seat and the second movable seat respectively. This allows the suction cup at the bottom of the second movable seat to move independently and stably adsorb the corresponding position on the workpiece. In conjunction with the support sleeve and its internal resistance spring and telescopic rod, a certain reset effect is achieved, so that after the workpiece is released, the suction cup can be pulled back to its original position for the next use. This design allows it to handle workpieces of different shapes during use, thereby achieving the purpose of stably adsorbing the workpiece and greatly improving the applicability of the equipment.

[0014] 2. By setting limiting blocks on the inner walls of both sides of the support sleeve, and in conjunction with the limiting blocks set on both sides of the top of the telescopic rod, the extension length of the telescopic rod is limited, so as to prevent the telescopic rod from detaching from the support sleeve, which would prevent it from forming an effective connection with the movable frame and thus cause the suction cup to fail to reset.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4This utility model provides a technical solution for a double-row guide rail suction cup device, including a flexible guide rail 1, a movable frame 3, and a support sleeve 8. Multiple first movable seats 2 are fixedly connected to the bottom of the flexible guide rail 1. The bottom end of each first movable seat 2 is movably connected to the movable frame 3. The bottom of the movable frame 3 is movably connected to a second movable seat 4. A suction cup 5 is fixedly installed at the bottom of the second movable seat 4. Connecting plates 17 are fixedly welded to both ends of the movable frame 3. The connecting plates 17 are semi-circular plate structures. The connecting plates 17 at both ends of the movable frame 3 extend into the interiors of the first movable seats 2 and the second movable seats 4, respectively, and are movably connected to them via pins 6. A support sleeve 8 is also provided between the first movable seats 2 and the movable frame 3. The top end of the support sleeve 8 is movably connected to the first movable seat 2 via a movable connecting seat 9. A telescopic rod 11 is slidably provided inside the support sleeve 8. A resistance spring 10 is provided at one end of the telescopic rod 11 extending into the interior of the support sleeve 8. One end of the telescopic rod 11 is movably connected to the movable frame 3 via the movable connecting seat 9.

[0022] Specifically, the support sleeve 8 has limit grooves 12 on both sides inside, and limit blocks 13 are provided on both sides of the top of the telescopic rod 11. The limit blocks 13 extend into the interior of the limit grooves 12 and are slidably connected to their inner walls.

[0023] Specifically, a vacuum generator 14 is provided in the middle of the two suction cups 5 in the same group at the bottom of the flexible guide rail 1, and the vacuum generator 14 is fixedly installed at the bottom of the flexible guide rail 1.

[0024] Specifically, the bottom of the flexible guide rail 1 is also provided with a pipe 15, which is connected in parallel with the vacuum generator 14 and the suction cup 5.

[0025] Specifically, a manual master valve 16 is installed at one end of the pipeline 15, and the end of the pipeline 15 with the manual master valve 16 is connected to the gas source.

[0026] Specifically, a vacuum release valve 7 is provided on one side of the top of the suction cup 5.

[0027] In this embodiment, during use, an air source is connected through pipe 15. The airflow passes through vacuum generator 14, creating a vacuum on the suction cup 5 placed on the workpiece surface. This generates suction force in the suction cup 5 and maintains a vacuum state inside the suction cup 5, thereby adsorbing the workpiece. When the workpiece surface is not planar at the position of the same set of suction cups 5, during the adsorption process, the suction cup 5 that has not adsorbed the workpiece will rotate at a certain angle around the pin 6 on the first movable seat 2 under the action of the adsorption force, causing the suction cup 5 to rotate downward. At the same time, the telescopic rod 11 inside the support sleeve 8 is stretched outward by 11 times, and stretched... The resistance spring 10 allows the suction cup 5 to have a certain degree of mobility, thereby adsorbing the non-planar position of the workpiece surface to be adsorbed. At this time, the corresponding position of the flexible guide rail 1 will bend laterally to cope with the extension of the suction cup 5. Together with the second movable seat 4, the pin 6 and the connecting plate 17, the suction cup 5 has the function of self-flipping, so as to ensure that the suction cup 5 can be closely attached to the surface of the workpiece to be adsorbed, thereby achieving a stable adsorption effect. This design allows it to cope with workpieces of different shapes during use, thereby achieving the purpose of stable adsorption of workpieces and greatly improving the applicability of the equipment.
