Description

Technical Field

[0001] This utility model relates to the field of friction stir welding technology, specifically to a pipeline handling mechanism for friction stir welding equipment. Background Technology

[0002] Friction stir welding equipment generally consists of a welding machine tool, welding tools, a fixture system, and a control system. The welding machine tool has a moving component that can perform vertical downward or upward reset movements. A spindle is located at the bottom of the moving component, and a rotating welding tool (such as a stirring needle) is connected to the bottom of the spindle. During operation, the vertical downward movement of the spindle can drive the rotating welding tool to penetrate the workpiece. When the welding tool penetrates to the specified depth, the spindle will drive the welding tool to move along the welding direction to achieve welding work in the specified direction. After welding is completed, the upward reset movement of the spindle will drive the welding tool to reset upward.

[0003] During the use of the aforementioned friction stir welding equipment, technicians typically install a pressure roller mechanism on the main shaft to ensure stable movement of the welding tool along the welding direction on the workpiece. Specifically, the pressure roller mechanism includes a cylinder fixedly mounted on the main shaft and a pressure roller rotating at the piston rod of the cylinder. The pressure roller mechanism operates as follows: After the workpiece is placed in the designated position, i.e., after the welding direction is determined, the pressure roller mechanism rotates until it reaches the designated position. At this point, viewed along the welding direction, the pressure roller mechanism is located at the front end of the welding tool. During welding, the cylinder drives the pressure roller downwards to contact the workpiece, and the main shaft moves the welding tool along the welding direction. During this process, the pressure roller remains at the front end of the welding tool and rolls and presses firmly against the workpiece.

[0004] Based on the working principle of the pressure roller mechanism described above, when welding different types of workpieces, the welding direction of each workpiece may differ. Therefore, the position of the pressure roller mechanism needs to be adjusted according to the welding direction of the workpiece to ensure it remains at the front end of the welding tool along the welding path. However, since the cylinder in the pressure roller mechanism requires pipes and wiring to operate normally, these pipes and wiring are typically fixed at the moving component, with their ends connected to the corresponding positions on the cylinder. Sufficient movement allowance is provided for cylinder rotation in both pipes and wiring. However, technicians have found that in actual use, this reserved movement allowance results in significant oscillation during cylinder rotation. This not only loosens the pipe and wiring joints at the cylinder but can also cause the pipes and wiring to become entangled in other components, interfering with the welding process and affecting normal welding operations.

[0005] To address these issues, we propose a pipeline handling mechanism for friction stir welding equipment. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the prior art by proposing a pipeline winding mechanism for friction stir welding equipment. This winding mechanism uses winding and unwinding parts to wind or unwind the pipeline in the corresponding working state, so that the pipeline is always kept taut, and the protective cover can be used to further protect the pipeline.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A pipeline winding mechanism for friction stir welding equipment includes a first winding and a second winding component mounted on a moving assembly. The first winding and the second winding component are connected to the pipeline, and the second winding and the second winding component are connected to the line. When the pressure roller mechanism rotates with the main shaft, the first winding and the second winding component are used to synchronously wind up or unwind the pipeline.

[0009] As a further embodiment of this invention, the receiving mechanism also includes a protective cover disposed on the moving component. The protective cover is used to house a portion of the pipes and lines inside it, so that when the pressure roller mechanism rotates with the main shaft, the portion of the pipes and lines is restricted to move within the protective cover.

[0010] As a further embodiment of this utility model: the protective cover includes a protective cylinder, the two ends of which are an open end and a sealing end, and the protective cylinder is set at the bottom of the movable component by means of its open end.

[0011] As a further embodiment of this utility model, the sealing end of the protective cylinder is provided with a first through hole for the passage of pipelines and lines.

[0012] As a further embodiment of this utility model, the sealing end of the protective cylinder is provided with a notch for avoiding the main shaft.

[0013] As a further embodiment of this utility model: a shelf is provided on the side of the moving component, and the first and second retractable components are both mounted on the moving component through the shelf, and a second through hole is provided on the shelf for pipes and lines to pass through.

[0014] As a further embodiment of this utility model: the first retractable component includes two automatic telescopic hose reels fixedly mounted on the shelf, and the two automatic telescopic hose reels are respectively used to connect to two pipes in the pressure roller mechanism.

[0015] As a further embodiment of this utility model: the second take-up and release component includes an automatic telescopic cable reel fixedly mounted on the shelf, the automatic telescopic cable reel being used to connect to the wiring in the pressure roller mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The pipeline winding mechanism of this friction stir welding equipment achieves automatic winding or unwinding of the pipeline as the pressure roller mechanism rotates with the main shaft through the synchronous operation of the first winding and unwinding components. This avoids large rotation amplitudes of the pipeline and lines, prevents pipeline entanglement, and greatly improves the working efficiency of the equipment and the convenience of pipeline management. At the same time, the design of the protective cover effectively protects the pipeline and lines, reduces damage caused by external factors, and improves the overall safety and stability of the equipment.

[0018] 2. The protective cover adopts a protective cylinder structure. Its open end and sealed end design allow pipelines to enter and exit in an orderly manner. At the same time, the protective cylinder is set at the bottom of the moving component by the open end, which not only facilitates installation and maintenance, but also ensures the stability and durability of the protective cover.

[0019] 3. The first through hole opened on the sealing end provides a through passage for pipelines and lines. This design not only ensures the smooth entry and exit of pipelines, but also avoids potential risks caused by pipelines being directly exposed to the external environment, further improving the protection performance of the equipment.

[0020] 4. The notch design at the sealing end cleverly avoids the main shaft, ensuring that the normal operation of the main shaft is not affected, while protecting the pipeline from interference from the movement of the main shaft, reflecting the precision and thoughtfulness of the design.

[0021] 5. The shelf on the side of the moving component provides a stable mounting platform for the first and second take-up and take-up components. At the same time, the design of the second through hole allows the pipeline to pass through smoothly. This layout is not only reasonable and compact, but also improves the overall aesthetics and practicality of the equipment. Attached Figure Description

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] like Figures 1-4 As shown, a pipeline handling mechanism for friction stir welding equipment includes a first take-up / untake-up component 1 and a second take-up / untake-up component 2. Both the first take-up / untake-up component 1 and the second take-up / untake-up component 2 are mounted on a moving assembly a on the friction stir welding equipment. Since a pressure roller mechanism b is provided on the moving assembly a, the cylinder in the pressure roller mechanism b needs to be equipped with pipelines and lines for use. Therefore, the first take-up / untake-up component 1 is connected to the pipeline for taking up or unwinding the pipeline, and the second take-up / untake-up component 2 is connected to the line for taking up or unwinding the line.

[0031] During the rotation of the pressure roller mechanism b driven by the main shaft c, the cylinder drives the pipes and wires on it to move accordingly. At this time, the first take-up / untake-down component 1 unfolds the pipes, and the second take-up / untake-down component 2 unfolds the wires, ensuring that the movement margin of the pipes and wires can match the corresponding action of the cylinder. Furthermore, the pipes and wires remain taut at all times, thus preventing significant swaying during the follow-up motion and reducing interference with other components. When the main shaft c drives the pressure roller mechanism b to reset and rotate, the cylinder drives the pipes and wires on it to move in the opposite direction. At this time, the first take-up / untake-down component 1 winds up the pipes, and the second take-up / untake-down component 2 winds up the wires, again maintaining the tautness of the pipes and wires.

[0032] It should be noted that the first winding / unwinding component 1 and the second winding / unwinding component 2 mentioned above can both be set with conventional technical means in the prior art, such as automatic telescopic hose reels and automatic telescopic cable reels. This article does not limit the type and structure of the first winding / unwinding component 1 and the second winding / unwinding component 2, as long as they can realize the automatic winding or unwinding function of pipes and lines. At the same time, the cylinder generally needs to be equipped with two pipes for use, so the first winding / unwinding component 1 generally includes two automatic telescopic hose reels set on the shelf 4. In some practical application scenarios, pipes can be wound or unwound using an air drum, and lines can be wound or unwound using an electric drum.

[0033] Furthermore, in order to facilitate the installation and maintenance of the first retractable component 1 and the second retractable component 2, a shelf 4 can be provided on the side of the moving component a. The first retractable component 1 and the second retractable component 2 are both mounted on the moving component a through the shelf 4, and the shelf 4 is provided with a second through hole 5 for pipes and lines to pass through.

[0034] Example 2:

[0035] This embodiment adds a protective cover 3 to the first embodiment. The protective cover 3 is set on the moving component a. The protective cover 3 is used to house the pipes and lines inside it. When the pressure roller mechanism b rotates with the main shaft c, the effect of the first take-up and release component 1 on the pipes will be restricted within the protective cover 3, and the effect of the second take-up and release component 2 on the lines will also be restricted within the protective cover 3. That is, during the operation of the first take-up and release component 1 and the second take-up and release component 2, the pipes and lines will be restricted to move within the protective cover 3, and the pipes and lines will be further protected, with good protection effect.

[0036] Specifically, the protective cover 3 includes a protective cylinder 301, with an open end and a sealed end at its two ends. The open end is arranged upward and the sealed end is arranged downward. The protective cylinder 301 is set at the bottom of the moving component a by its open end. A first through hole 302 for pipelines and lines to pass through is opened on the sealed end of the protective cylinder 301.

[0037] Pipelines and wiring can be assembled in various ways, and they can be installed in a way that adapts to different types of first take-up and second take-up components 1 and 2, as shown in the following two installation methods:

[0038] (1) One end of the pipeline and line is pre-connected to the corresponding supply source. Then, the other end of the pipeline and line can be passed through the opening end of the protective cylinder 301 and the first through hole 302 from top to bottom. Then, the pipeline and line end is installed at the corresponding interface of the cylinder to realize the normal operation of the cylinder. Then, the pipeline and line are connected to the first take-up and release member 1 and the second take-up and release member 2 respectively, so that the first take-up and release member 1 and the second take-up and release member 2 can drive the pipeline and line to perform take-up or undo actions respectively.

[0039] (2) One end of the pipeline and line is pre-connected to the corresponding supply source. Then, the other end of the pipeline and line can be passed through the first take-up and release member 1 and the second take-up and release member 2 respectively. Then, the end of the pipeline and line is passed through the opening end of the protective cylinder 301 and the first through hole 302 from top to bottom. Finally, the end of the pipeline and line is installed at the corresponding interface of the cylinder to realize the normal operation of the cylinder, so that the first take-up and release member 1 and the second take-up and release member 2 can drive the pipeline and line to perform take-up or unwinding actions respectively.

[0040] The installation method of the above-mentioned pipelines and lines is adapted to the selected type of the first retractor 1 and the second retractor 2. Under the above installation design, in order to ensure that the installation position of the protective cover 3 does not interfere with the normal operation of the spindle c, a notch 303 for avoiding the spindle c can be opened at the sealing end of the protective cylinder 301.

[0041] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
