Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically relating to a welding pressure sleeve compatible with welding equipment. Background Technology

[0002] When welding pipe fittings, it is often necessary to ensure the alignment accuracy of the two pipe fitting end faces so that the welded pipe fittings are on the same axis. Fixing the pipe fittings on both sides with clamps is also a common method.

[0003] However, existing clamping structures for pipe fittings often use triangular chucks or bolts for locking. While these methods can provide a secure hold, they are not very compatible. When clamping pipe fittings of different diameters, uneven force can easily cause deformation or scratches. Furthermore, the operation is quite complex and requires external tools for locking, making them impractical. Utility Model Content

[0004] The purpose of this invention is to provide a welding pressure sleeve compatible with welding equipment, which can use clamping components to clamp pipes of different diameters, so that the critical ends are in the welding station area, avoiding problems such as weld seam offset and misalignment caused by pipe shaking and displacement.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A welding pressure sleeve compatible with welding equipment includes a cylinder, a movable sleeve threadedly connected to the side wall of the cylinder, an inclined surface formed on the inner wall of the movable sleeve, a plurality of clamping components evenly arranged on the side wall of the cylinder, and an air blowing component also provided on the side wall of the cylinder.

[0007] Furthermore, the clamping assembly includes a movable rod movably connected to the side wall of the cylinder. One end of the movable rod abuts against the inclined surface, and the other end of the movable rod passes through the cylinder and is fixedly connected to an arc-shaped plate. A baffle is fixedly connected to the side wall of the movable rod, and a spring is sleeved on the side wall of the movable rod between the baffle and the arc-shaped plate.

[0008] Furthermore, the end face of the movable rod is rotatably connected with a ball bearing, which abuts against the inclined surface.

[0009] Furthermore, rubber pads are fixedly connected to the side wall of the arc-shaped plate near the center of the cylinder.

[0010] Furthermore, the air blowing assembly includes an annular groove inside the cylinder, a connector is fixedly connected to the side wall of the annular groove, the connector communicates with the annular groove, and a plurality of air outlet holes are provided on the side wall of the annular groove near the center of the cylinder.

[0011] Furthermore, all the air outlets are angled.

[0012] Furthermore, support plates are fixedly connected to both ends of the cylindrical sidewall.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model discloses a welding pressure sleeve compatible with welding equipment. Through the cooperation of a cylinder, a movable sleeve, a clamping assembly, and an air blowing assembly, the clamping assembly can strictly fix the pipe inside the cylinder, so that the critical end is in the welding station area, avoiding problems such as weld seam offset and misalignment caused by pipe shaking and displacement, ensuring the dimensional accuracy of the welded joint, and the clamping or releasing can be completed without the aid of other tools, making the operation relatively simple and convenient.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] Example 1:

[0023] like Figures 1-4 As shown, a welding pressure sleeve compatible with welding equipment includes a cylinder 1, a movable sleeve 2 threadedly connected to the side wall of the cylinder 1, an inclined surface 3 opened on the inner wall of the movable sleeve 2, a plurality of clamping components evenly arranged on the side wall of the cylinder 1, and an air blowing component also provided on the side wall of the cylinder 1.

[0024] like Figure 2 and Figure 3As shown, the clamping assembly includes a movable rod 4 movably connected to the side wall of the cylinder 1. One end of the movable rod 4 abuts against the inclined surface 3, and the other end of the movable rod 4 passes through the cylinder 1 and is fixedly connected to an arc-shaped plate 5. A baffle 6 is fixedly connected to the side wall of the movable rod 4, and a spring 7 is sleeved between the baffle 6 and the arc-shaped plate 5 on the side wall of the movable rod 4. When the movable sleeve 2 is rotated in the opposite direction, the spring 7 can drive the arc-shaped plate 5 into an expanded state, while ensuring that the ball bearing 8 can always be in contact with the inclined surface 3. Rubber pads 9 are fixedly connected to the side wall of the arc-shaped plate 5 near the center of the cylinder 1.

[0025] The clamping assembly allows for the opening and closing of the arc plate 5 by rotating the movable sleeve 2, thus adapting to clamping pipes of different diameters and increasing compatibility with pipes during welding. Furthermore, the threaded connection allows for manual rotation to control the clamping tightness without the need for external tools. In addition, the arc plate 5, when used in conjunction with the rubber pad 9, can effectively increase the friction between the plate and the pipe, thereby improving clamping stability.

[0026] like Figure 3 As shown, a ball bearing 8 is rolled onto the end face of the movable rod 4, and the ball bearing 8 abuts against the inclined surface 3. The ball bearing 8 reduces the friction between the movable rod 4 and the inclined surface 3, making the rotation of the movable sleeve 2 easier and smoother.

[0027] Support plates 13 are fixedly connected to the side walls of cylinder 1 near both ends.

[0028] The support plate 13 has an L-shaped structure and mounting holes are provided on its surface to facilitate its installation on welding equipment. Furthermore, the specifications of the support plate 13 are not limited to those in this solution and can be determined according to actual needs.

[0029] Example 2:

[0030] Based on Embodiment 1, this embodiment specifically discloses the cleaning structure for pipe fittings during welding;

[0031] like Figure 2 and Figure 4 As shown, the air blowing assembly includes an annular groove 10 inside the cylinder 1. A connector 11 is fixedly connected to the side wall of the annular groove 10. The connector 11 communicates with the annular groove 10. Several air outlet holes 12 are opened on the side wall of the annular groove 10 near the center of the cylinder 1.

[0032] All vents 12 are angled.

[0033] Specifically, during use, the external air pipe is inserted into the connector 11, and the gas is injected into the annular groove 10 and blown out from multiple air outlets 12 toward the welding position of the pipe fitting. Before welding, the dust and impurities on the surface of the pipe fitting are cleaned. After welding, the weld is cooled by increasing the airflow around the weld. It is highly practical.

[0034] The working principle of this utility model is as follows: First, the cylinder 1 is fixed in the corresponding position of the welding equipment by the support plate 13. When in use, two cylinders can be set on the same horizontal plane. The area between the two cylinders 1 is the welding area. When welding the pipe fittings, the pipe fittings on both sides are inserted into the cylinder 1 respectively and located between multiple arc plates 5. Then, the movable sleeve 2 is rotated to move to the left. The inclined surface 3 of the movable sleeve 2 is used to squeeze the movable rod 4. The movable rod 4 drives the arc plate 5 to move towards the pipe fitting side to clamp the pipe fitting, so that the end faces of the pipe fittings on both sides are facing each other, thus accommodating pipe fittings of different diameters.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
