Description

Technical Field

[0001] This utility model relates to a laser welding flipping mechanism, which is mainly applicable to the welding of metal cylindrical workpieces and belongs to the field of welding tooling technology. Background Technology

[0002] Laser welding machines use high-energy laser pulses to locally heat materials in a small area, allowing the energy of the laser radiation to diffuse into the interior of the material through heat conduction, melting the material and forming a specific molten pool. Currently, in the process of using laser welding machines, it is necessary to clamp, fix and flip the workpiece to facilitate the welding work.

[0003] Traditional laser welding machines use a purely mechanical flipping mechanism, where the workpiece is manually fixed to a specific position on the flipping mechanism with screws, or the workpiece is manually flipped and then fixed in position using a ratchet mechanism. This has the following drawbacks:

[0004] a. The flipping mechanism has no electric flipping function and can only be manually flipped and fixed. When the workpiece has a certain weight, multiple people need to work together at the same time, which not only increases the workload but also affects work efficiency.

[0005] b. The flipping mechanism is not flexible enough and is not convenient to adjust and use, which cannot meet the need for the workpiece to be flipped freely, resulting in insufficient precision in welding processing;

[0006] c. The flipping mechanism does not have an automatic self-locking function. Generally, the self-locking of the flipping mechanism is achieved manually by using screws or a fixing structure, which is cumbersome and time-consuming.

[0007] d. The flipping mechanism has poor safety. When the workpiece falls or the self-locking structure malfunctions, it can easily cause injury to the workers.

[0008] Therefore, there is an urgent need to develop and design a new flipping mechanism suitable for laser welding. Summary of the Invention

[0009] To address the aforementioned technical problems, this utility model provides a laser welding flipping mechanism that achieves automatic self-locking at any flipping position through a bidirectional free flipping function.

[0010] To achieve the above objectives, this utility model provides a laser welding flipping mechanism, including a base, a support assembly mounted on the base, and a flipping assembly and a positioning assembly mounted on the support assembly;

[0011] The bracket assembly includes a left front column, a right front column, and a rear bracket respectively installed at the left front, right front, and rear of the base;

[0012] The flipping assembly includes two bearings symmetrically mounted on the inner sides of the left and right front columns, a contour frame for placing the workpiece, and two screws; the contour frame includes a circular base, an arc-shaped fence mounted on the front of the top of the circular base, two connecting shafts symmetrically mounted on both sides of the upper part of the arc-shaped fence, and a fixing ring mounted in the middle of the rear of the circular base; the two connecting shafts are respectively inserted into the corresponding bearings and connected together by corresponding screws;

[0013] The positioning assembly includes a bidirectional self-locking winch installed on the outer side of the left front column, an anti-jump guide wheel assembly installed on the rear bracket, and a lifting rope; one end of the lifting rope is wound around the bidirectional self-locking winch, and the other end extends vertically downward after passing around the anti-jump guide wheel assembly and connects to the fixing ring of the contour frame, and can drive the contour frame and the workpiece inside to rotate up and down.

[0014] Furthermore, the rear support includes a left rear column and a right rear column respectively installed on the left rear and right rear of the base, a top square column connecting the left rear column and the right rear column, and an extension square column vertically installed on the front side of the top square column.

[0015] The anti-jump guide wheel assembly includes anti-jump guide wheel one, anti-jump guide wheel two, anti-jump guide wheel three, and anti-jump guide wheel four; anti-jump guide wheel one is installed on the outer side of the right rear column; anti-jump guide wheel two is installed on the right end of the top surface of the top square column; anti-jump guide wheel three is installed in the middle of the top surface of the top square column; and anti-jump guide wheel four is installed on the front end of the top surface of the extended square column.

[0016] Furthermore, the flipping assembly further includes two washers; the two washers are respectively placed between the two connecting shafts and the corresponding screws.

[0017] Furthermore, the lifting rope can drive the contour frame and the workpiece inside to rotate up and down by ±60°.

[0018] In summary, this utility model uses a support assembly as a support, and fixes both sides of the contour frame to the support assembly through bearings with seats, connecting shafts, washers, and screws. The lifting rope is operated by a two-way self-locking winch, so that the other end of the lifting rope can be twisted up and down, thereby driving the contour frame and the workpiece inside to adjust and rotate arbitrarily and quickly in the vertical plane, and can lock the position.

[0019] Compared with existing products, the technical advantages of this utility model are as follows:

[0020] 1. Using contoured parts to place the workpiece is especially suitable for welding cylindrical metal workpieces. It not only eliminates the need for manual contact with the workpiece, avoiding the tedious manual operation of workers, reducing the workload and improving welding efficiency, but also prevents the workpiece from falling during the flipping process, thus enhancing the stability of the welding operation.

[0021] 2. It has the function of flipping up and down by ±60°, which not only allows for arbitrary and quick adjustment of the flipping angle, but also allows for locking any flipping position, improving the flexibility of use and making the processing and welding more precise.

[0022] 3. It has an automatic self-locking function at any position during flipping, which ensures a more stable process for flipping and welding workpieces and improves the safety of welding operations. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings. In the description of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0028] In the following description, reference is made to the accompanying drawings, which illustrate several embodiments of the present application. It should be understood that other embodiments may also be used, and changes in mechanical composition, structure, electrical, and operation may be made without departing from the spirit and scope of this disclosure. The following detailed description should not be considered limiting, and the scope of the embodiments of the present application is defined only by the claims of the published patents. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the present application. Spatially related terms, such as “upper,” “lower,” “left,” “right,” “front,” “rear,” etc., may be used herein to illustrate the relationship between one element or feature shown in the figures and another element or feature.

[0029] like Figures 1 to 3 As shown, this embodiment provides a laser welding flipping mechanism, including a base 1, a support assembly 2 mounted on the base 1, and a flipping assembly and a positioning assembly mounted on the support assembly 2, which are described in detail below.

[0030] like Figure 1 As shown, the bracket assembly 2 includes a left front column, a right front column, and a rear bracket, which are respectively installed at the left front, right front, and rear of the base 1. In specific implementations, the rear bracket can be designed into various shapes as needed, such as a rectangular bracket mainly composed of a left rear column, a right rear column, and a top square column.

[0031] like Figure 2 , Figure 3 As shown, the flipping assembly includes two bearings 3 with seats symmetrically mounted on the inner sides of the left front column and the right front column, a contour frame 4 for placing the workpiece, and two screws 6.

[0032] The profiling frame 4 includes a circular base 41, an arc-shaped fence 42 installed on the front top of the circular base 41, two connecting shafts 43 symmetrically installed on both sides of the upper part of the arc-shaped fence 42, and a fixing ring 44 installed in the middle of the rear part of the circular base 41. In a specific implementation, the arc-shaped fence 42 can be designed as a semi-circular arc concentric with the circular base 41, and the two connecting shafts 43 are symmetrically placed along the diameter of the circular base 41, thereby facilitating the rotation of the entire profiling frame 4.

[0033] The two connecting shafts 43 are respectively inserted into the corresponding bearings 3 and connected together by corresponding screws 6. In specific implementation, a mounting through hole is opened at the top of the left front column and the right front column, and the center hole of the bearing 3 is aligned with the corresponding mounting through hole, so that the connecting shaft 43 is fixed at the mounting through hole by the screws 6.

[0034] In other embodiments, such as Figure 3As shown, the flipping assembly also includes two washers 5; the two washers 5 are respectively placed between the two connecting shafts 43 and the corresponding screws 6.

[0035] It should be noted that, with the support assembly 2 as the support, the two sides of the contour frame 4 are fixed to the support assembly 2 through the seated bearing 3, connecting shaft 43, washer 5, and screw 6, so that the contour frame 4 can rotate up and down in the vertical plane with the seated bearing 3 as the axis. Furthermore, due to the size limitations of the suspension rope 8 and the contour frame 4, the contour frame 4 can only achieve a 120° vertical rotation range, which is sufficient for actual working requirements.

[0036] like Figure 1 As shown, the positioning assembly includes a bidirectional self-locking winch 7 installed on the outer side of the left front column, an anti-jump guide wheel assembly installed on the rear bracket, and a hoisting rope 8; one end of the hoisting rope 8 is wrapped around the bidirectional self-locking winch 7, and the other end extends vertically downward after passing over the anti-jump guide wheel assembly and connects to the fixing ring 44 of the contour frame 4.

[0037] In other embodiments, such as Figure 1 As shown, the anti-jump guide wheel assembly includes anti-jump guide wheel one 9, anti-jump guide wheel two 10, anti-jump guide wheel three 11, and anti-jump guide wheel four 12; the rear bracket includes a left rear column and a right rear column respectively installed on the left rear and right rear of the base 1, a top square column connecting the left rear column and the right rear column, and an extension square column vertically installed on the front side of the top square column.

[0038] Wherein, the central axis of the bidirectional self-locking winch 7 is perpendicular to the outer side of the right front column; the first anti-jump guide wheel 9 is installed on the outer side of the right rear column, and its central axis is perpendicular to the outer side of the right rear column; the second anti-jump guide wheel 10 is installed on the right end of the top surface of the top square column, and its central axis is parallel to the top surface of the top square column; the third anti-jump guide wheel 11 is installed in the middle of the top surface of the top square column, and its central axis is perpendicular to the top surface of the top square column; the fourth anti-jump guide wheel 12 is installed on the front end of the top of the extended square column, and its central axis is perpendicular to the left side of the extended square column.

[0039] In this way, the other end of the suspension rope 8 starts from the bidirectional self-locking winch 7, first turns around the anti-jump guide wheel 1 9, then extends vertically upward along the right rear column, then turns around the anti-jump guide wheel 2 10, then extends horizontally to the left along the top square column, then turns around the anti-jump guide wheel 3 11, then extends horizontally forward along the extended square column, then turns around the anti-jump guide wheel 4 12, then extends vertically downward until it reaches the fixing ring 44 connecting to the contour frame 4. By manipulating the bidirectional self-locking winch 7, the contour frame 4 can be pulled up and down by the suspension rope 8.

[0040] In operation, the workpiece is first placed inside the contour frame 4, which is particularly suitable for placing cylindrical metal workpieces. Next, the lifting rope 8 is manipulated by the bidirectional self-locking winch 7, causing the other end of the rope 8 to twist up and down via the anti-jump guide wheel assembly. This causes the contour frame 4 and the workpiece inside to rotate vertically, with the horizontal plane as a reference. The workpiece inside the contour frame 4 can rotate freely ±60° vertically. Then, through the automatic self-locking function of the bidirectional self-locking winch 7, the contour frame 4 and the workpiece inside can be fixed at any rotation angle, allowing welding operations to begin.

[0041] In this way, when using this utility model to weld metal cylindrical workpieces, it is not only convenient to place and fix the workpiece, improving work efficiency, but also allows for arbitrary and quick adjustment of the workpiece's flipping angle, improving the flexibility of use and enhancing the precision of welding. Furthermore, it allows for locking the position at any flipping angle, improving the safety and stability of welding.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
