[0002] During the process of electrolytic polishing the inner surface of pipe fittings, a clamp is a specially designed tool or device used to hang and fix pipe fittings, ensuring that they can be safely immersed in and removed from the electrolytic cell while maintaining a stable position and posture. The main structure of this type of clamp usually includes a corrosion-resistant hanging part and a fixing part. Through the design of these components, it is ensured that the pipe fittings are safely hung and stable in the electrolytic cell. Its working principle lies in providing a stable hanging and fixing mechanism to ensure that the surface of the pipe fittings uniformly contacts the electrolyte, thereby achieving a consistent electrolytic polishing effect. However, at present, the number of pipe fittings that can be assembled by the electrolytic polishing clamp for pipe fittings during use is small. Usually, each pipe fitting needs to be assembled with an individual clamp, and the operator needs to spend a lot of time assembling and adjusting the clamp. Moreover, each clamp requires a certain amount of space for operation and storage. Especially for a large number of pipe fittings that need to be processed simultaneously, it increases the complexity and difficulty of personnel operation. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5 , an embodiment provided by the present utility model: an electrolytic polishing fixture for the inner surface of a pipe fitting, including a cross beam 1 and right-angle ear seats 2 fixed at both ends of the cross beam 1. A plurality of U-shaped foot platforms 3 are equidistantly installed at the bottom end of the cross beam 1 in the horizontal direction, and a square-mouth longitudinal beam 301 is fixed at the bottom end of the U-shaped foot platform 3. A rectangular convex block is fixed at the bottom end of the cross beam 1. A plurality of internal threaded holes for bolting to the rectangular convex block are provided on the front and rear outer walls of the U-shaped foot platform 3;

[0019] A plurality of equally spaced shaft support plates 5 are installed on the outer wall of one side of the U-shaped foot platform 3, and a longitudinal shaft 6 is rotatably installed between the plurality of shaft support plates 5 in the Y-axis direction. A first crawler drive structure 7 for maintaining power transmission is installed between the plurality of longitudinal shafts 6 in the X-axis direction. A plurality of pipe fitting hanging structures 10 for hanging pipe fittings are fixed on the surface of the longitudinal shaft 6. The arrangement of the plurality of square-mouth longitudinal beams 301 and the longitudinal shaft 6 allows the parallel suspension of pipe fittings, which can effectively utilize the space of the production site, optimize the layout of the production line, and is suitable for large-scale production environments in limited spaces;

[0020] A rotary drive module 9 for driving one of the longitudinal shafts 6 to rotate is installed at one end of the surface of the U-shaped foot platform 3;

[0021] A plurality of loop-shaped bolt sleeves 4 are sleeved and bolted on the surface of the U-shaped foot platform 3, and one end of the outer wall of the loop-shaped bolt sleeve 4 is fixedly connected to one end of the shaft support plate 5;

[0022] The pipe fitting hanging structure 10 includes a spoon plate 1001 fixed on the surface of the longitudinal shaft 6, a connecting plate 1002 installed at the bottom end of the spoon plate 1001, and a docking column 1003 installed on the outer wall of one side of the connecting plate 1002. The extending direction of the docking column 1003 is perpendicular to the extending direction of the connecting plate 1002; when the staff places the pipe fitting on the pipe fitting hanging structure 10, the staff docks one of the pipe ends of the pipe fitting with the docking column 1003 so that the pipe fitting is inserted on the docking column 1003. In this process, the spoon plate 1001 and the connecting plate 1002 serve the purpose of connecting the docking column 1003 and the longitudinal shaft 6;

[0023] The pipe fitting to be electrolytically polished should not be too long, otherwise the pipe fitting will fall off from the docking column 1003. It is applicable to some pipe joints and short pipe joints. If long pipe fittings need to be clamped, long-specification docking columns 1003 can be selected to ensure the stable clamping of long pipe fittings;

[0024] One end of the surface of the docking column 1003 is sleeved with a rubber sleeve. An external thread groove is arranged on the outer peripheral surface of the docking column 1003, and an internal thread groove for cooperating with one end of the docking column 1003 is arranged inside the connecting plate 1002. The internal thread groove and the external thread groove enable the connecting plate 1002 and the docking column 1003 to be quickly assembled;

[0025] The rotary drive module 9 includes a support box 8 installed at one end of the surface of the cross beam 1, a reduction motor installed inside the support box 8, and a second crawler transmission structure installed at the output end of the reduction motor for driving one of the vertical shafts 6 to rotate. The structural designs of the rotary drive module 9 and the first crawler transmission structure 7 enable multiple vertical shafts 6 to rotate together. When the rotary drive module 9 uses a reduction motor, the reduction motor increases the torque by reducing the speed, enabling the multiple vertical shafts 6 to operate efficiently at a lower speed and maintain a stable angle;

[0026] The first crawler transmission structure 7 and the second crawler transmission structure can also be replaced with a sprocket chain transmission structure, enabling the shafts to rotate more stably and preventing the shafts from slipping.

[0027] When the embodiment of the present application is in use, first, the cross beam 1 is installed on the lifting equipment through two right-angle ear seats 2 in a bolted manner. The external lifting equipment is used to control whether the fixture is immersed in or withdrawn from the electrolytic cell. Subsequently, the staff places multiple pipe fittings to be electrolytically polished one by one on the pipe fitting lifting and supporting structure 10, and the end of the pipe fitting is stably docked with the pipe fitting lifting and supporting structure 10. At this time, the pipe fitting lifting and supporting structure 10 is in a horizontal state, and the connected pipe fittings are in a vertical state. Then the staff starts the rotary drive module 9 to work. The rotary power of the rotary drive module 9 is transmitted to one of the vertical shafts 6, and the remaining parallel vertical shafts 6 also rotate synchronously and in the same direction under the drive of the first crawler transmission structure 7. Then the vertical shafts 6 and the pipe fitting lifting and supporting structure 10 rotate counterclockwise until the central axis of the pipe fitting deviates from the vertical direction, making the pipe fitting in an inclined upward state. Subsequently, the lifting equipment controls the fixture and the assembled pipe fittings to be immersed in the electrolytic cell for electrolytic polishing by the electrolytic cell. After introducing multiple vertical shafts 6 and multiple pipe fitting lifting and supporting structures 10 into the fixture, multiple pipe fittings can be assembled and processed simultaneously, effectively expanding the number of pipe fittings processed in a single production, thereby improving the batch processing capacity of the pipe fittings in the electrolytic polishing process. Moreover, the operator can easily fix multiple pipe fittings on the pipe fitting lifting and supporting structure 10 during the assembly stage, and after the processing is completed, the pipe fittings can also be quickly removed from the fixture, reducing the time and labor intensity of manual workpiece assembly and providing convenience for the operation.
