Description

Technical Field

[0001] This utility model belongs to the field of workpiece processing technology, and relates to a welding line side-pushing mechanism and a marine group-erecting welding line side-pushing device. Background Technology

[0002] In the orderly operation of a small assembly line, precise workpiece orientation adjustment is undoubtedly the absolute key prerequisite for the smooth execution of subsequent complex processing steps such as back welding. Currently, in actual production scenarios, the condition of incoming workpieces varies greatly, potentially exhibiting shape deviations, dimensional tolerances, surface unevenness, and many other issues. These problems can easily cause misalignment during workpiece movement on the assembly line. Once workpiece misalignment occurs, subsequent processing steps such as back welding cannot accurately position the workpiece. This not only leads to a significant reduction in processing efficiency, requiring frequent position calibration and rework, but also severely impacts processing quality, increasing product defect rates and production costs. For example, in the production of certain ship components with extremely high welding precision requirements, welding position deviations caused by workpiece misalignment may prevent the component's strength and sealing performance from meeting design standards, thereby affecting the overall performance and safety of the ship.

[0003] In summary, there is an urgent need in the market for a new type of efficient and reliable workpiece posture adjustment side-pushing mechanism, which is of great significance for improving the production efficiency and product quality of small-scale assembly lines. Utility Model Content

[0036] Example 1

[0037] The welding line side-pushing mechanism in this embodiment includes the following:

[0038] Drive Source: The side-push mechanism is equipped with a powerful side-push drive source, which is diverse in type, including but not limited to motors, hydraulic cylinders, and pneumatic cylinders. These drive sources can provide stable and controllable power output to meet the requirements of side-push force and speed under different working conditions. For example, when handling large and heavy workpieces, a motor with a large output torque or a hydraulic cylinder that provides strong thrust can be selected; while for some scenarios with high response speed requirements, the pneumatic cylinder can achieve efficient side-push operation due to its rapid action characteristics.

[0039] Transmission Components: The drive unit is tightly connected to the side push rod via a specific connection method, precisely transmitting the power generated by the drive source to the side push rod. The side push rod is cleverly positioned within the push rod guide, whose design ensures that the side push rod can move precisely along a predetermined straight trajectory, thereby ensuring the stability and accuracy of the side push operation. In actual design, to pursue even higher motion precision, more advanced linear motion mechanisms such as guide rails and sliders can be used to replace the traditional push rod guide slots. The guide rail and slider mechanism, with its high-precision manufacturing process and excellent motion smoothness, can significantly improve the overall performance of the side push mechanism.

[0040] Push plate adjustment: Multiple equally spaced slots are evenly distributed above the side push bar, facilitating the flexible installation of the push block. In actual production, operators can accurately place the push block into the corresponding slot according to the different widths of the incoming parts. This design greatly enhances the versatility and adaptability of the side push device, enabling it to easily handle the processing needs of parts of various sizes and specifications.

[0041] Example 2

[0042] The side-push device for the marine substation welding line in this embodiment mainly consists of three core parts: a conveyor roller conveyor, a side-push mechanism, and a positioning control mechanism. These parts work together to achieve precise attitude adjustment and stable pushing of the workpiece.

[0043] The marine substation welding line side thruster in this embodiment includes:

[0044] The welding line side-pushing mechanism, conveyor rollers, and positioning control mechanism in Example 1.

[0045] The positioning control mechanism mainly consists of two key parts: a flexible guard and a positioning sensor. The flexible guard acts as a soft protective barrier, effectively preventing the incoming material from directly impacting the roller conveyor side guard after being pushed by the pusher, thus ensuring smooth operation of the entire mechanism. Meanwhile, the positioning sensor acts like a sensitive "sentinel," monitoring the workpiece's position in real time. When the workpiece is pushed to the predetermined position, it quickly sends a sensing signal, providing accurate position information for subsequent processing steps, achieving automated and precise control of the entire processing flow.

[0046] In this embodiment, during actual use, the drive unit 1 drives the side push rod 21 to move linearly within the push rod guide 32. The push block 4 is positioned appropriately in the slot 22 according to the width of the incoming material. The length of the push block 4 to the side hard limit 51 minus the width of the incoming material is less than the stroke of the drive unit. After the incoming material arrives, the conveyor roller 5 stops rotating, and the drive unit 1 is activated, driving the push block 4 towards the side hard limit 51. Once the proximity switch 52 senses the product, the drive unit 1 stops, ensuring the material is clamped between the push block 4 and the side hard limit 51. The drive unit then reverses its direction, releasing the push block 4. At this point, the conveyor roller 5 continues to run, and the material flows downwards into the processing area.

[0047] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0048] As used in this invention, the term "comprising" is an open-ended expression, meaning it includes the contents specified in this invention, but does not exclude other aspects.

[0049] As used in this invention, the term "and / or" includes any one and all combinations of one or more of the related listed items.

[0050] The scope of protection of this utility model is not limited to the above embodiments. Any variations and advantages that can be conceived by those skilled in the art without departing from the spirit and scope of the utility model are included in this utility model and are protected by the appended claims.
