Description

Technical Field

[0001] This utility model relates to the technical field of welding machines, and in particular to a material ejector mechanism for a welding machine. Background Technology

[0002] Laser welding uses high-energy laser pulses to locally heat a small area of ​​material. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material and forming a specific molten pool. It is a new type of welding method.

[0003] Laser welding machines are also a commonly used welding equipment. They are usually equipped with a material-ejecting mechanism. A utility model patent with the existing patent publication number CN218874095U discloses a laser welding machine, which includes a worktable, a welding mechanism, a conveying mechanism, a feeding mechanism, a storage mechanism, a pressing mechanism, a material-ejecting mechanism, and a material-unloading mechanism. The material-ejecting mechanism is located on the worktable and below the storage mechanism for placing the plate to be welded upwards.

[0004] The top material mechanism on the laser welding machine in the aforementioned patent has certain drawbacks in use. When the piston rod of the top material cylinder retracts and the upper top plate descends, the buffering effect on the upper top plate is relatively poor, resulting in insufficient practicality. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a welding machine top material mechanism that can improve the buffering effect when the top plate descends and improve its practicality.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a material-ejecting mechanism for a welding machine, comprising a base plate, on which two sets of mounting brackets for mounting onto a workbench are fixedly mounted, and a material-ejecting cylinder is fixedly mounted on the base plate. A material-ejecting plate is fixedly connected to the output end of the material-ejecting cylinder. A buffer mechanism is provided at the top of each of the two sets of mounting brackets. The buffer mechanism includes a buffer plate, and a sliding rod is provided at the bottom end of the buffer plate. A sleeve plate is provided on the mounting bracket, and the sliding rod is slidably mounted on the sleeve plate. Two sets of guide holes are symmetrically arranged on the mounting bracket, and two sets of guide rods are symmetrically slidably mounted on the mounting bracket through the cooperation of the guide holes. Ear plates are fixedly provided on the outer sides of each set of guide rods, and the ear plates are integrally formed with the guide rods. A buffer spring is fitted on each set of guide rods, and both ends of the buffer spring are respectively connected to the mounting bracket and the guide rod. Two sets of connecting seats are symmetrically fixed at the bottom end of the buffer plate, and support rods are hinged to each set of connecting seats. The bottom ends of the two sets of support rods are rotatably connected to the two sets of ear plates.

[0008] Preferably, the slide rod and the sleeve plate are provided in four sets. The four sets of slide rods are symmetrically fixedly connected to the bottom end of the buffer plate, and the four sets of sleeve plates are symmetrically fixedly connected to the upper sides of the left and right sides of the mounting frame. The four sets of slide rods are slidably installed on the sleeve plates respectively.

[0009] Preferably, both sets of buffer plates have a buffer pad fixedly connected to their top ends.

[0010] Preferably, each of the four sets of sliding rods has a limiting block fixedly provided at its bottom end.

[0011] Preferably, a sliding sleeve is fixedly installed in the guide hole of each of the two sets of mounting brackets.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, after the top plate is raised, the buffer plate is initially in a raised state, and the inner sides of the two sets of guide rods abut against each other. When the piston rod in the top plate cylinder retracts, the top plate cylinder drives the top plate to move down. During the downward movement of the top plate, the bottom end of the top plate will first contact the top end of the buffer plate, and as the top plate moves down, it pushes the buffer plate to move downward, causing the buffer plate to push the slide rod to slide down along the sleeve plate. This causes the buffer plate to pull the guide rod outward through the support rod, compressing the buffer spring. When the top plate cylinder is fully retracted, the top plate descends to the lowest position, and the buffer spring is no longer compressed. By compressing the buffer spring, a buffering effect is achieved when the top plate descends, thereby improving the buffering effect when the top plate descends and improving practicality.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. Example

[0019] Please see Figures 1-4 This utility model discloses a material-ejecting mechanism for a welding machine, comprising a base plate 1. Two sets of mounting brackets 2 for mounting onto a workbench are fixedly mounted on the base plate 1. A material-ejecting cylinder 13 is fixedly mounted on the base plate 1, and a material-ejecting plate 14 is fixedly connected to the output end of the material-ejecting cylinder 13. Each of the two sets of mounting brackets 2 has a buffer mechanism at its top, comprising a buffer plate 3. A sliding rod 4 is provided at the bottom end of the buffer plate 3. A sleeve plate 5 is provided on the mounting bracket 2, and the sliding rod 4 is slidably mounted on the sleeve plate 5. Two sets of guide holes are symmetrically arranged on the mounting bracket 2. Two sets of guide rods 6 are symmetrically slidably arranged on the mounting bracket 2 through the cooperation of the guide holes. Ear plates 7 are fixedly mounted on the outer sides of each set of guide rods 6, and the ear plates 7 are integrally formed with the guide rods 6. A buffer spring 8 is fitted onto each set of guide rods 6, and the two ends of the buffer spring 8 are respectively connected to the mounting bracket 2 and the guide rod 6. Two sets of connecting seats 9 are symmetrically fixed at the bottom end of the buffer plate 3, and each set of connecting seats 9 is hinged to... Support rod 10, the bottom ends of two sets of support rods 10 are rotatably connected to two sets of ear plates 7 respectively; in use, after the top plate 14 is raised, the buffer plate 3 is initially in a raised state, and the inner sides of the two sets of guide rods 6 abut against each other. When the piston rod in the top cylinder 13 retracts, the top cylinder 13 drives the top plate 14 to move down. During the downward movement of the top plate 14, the bottom end of the top plate 14 will first contact the top end of the buffer plate 3, and as the top plate 14 moves down, it pushes the buffer plate 3 to move downward, so that the buffer plate 3 pushes the slide rod 4 to slide down along the sleeve plate 5, and then the buffer plate 3 pulls the guide rod 6 outward through the support rod 10, so that the buffer spring 8 is compressed. When the top cylinder 13 is fully retracted, the top plate 14 descends to the lowest position, and the buffer spring 8 is no longer compressed. By compressing the buffer spring 8, the buffer effect of the top plate 14 when it descends is achieved, thereby improving the buffering effect when the top plate descends and improving practicality.

[0020] Both the slide rod 4 and the sleeve plate 5 are provided with four sets. The four sets of slide rods 4 are symmetrically fixedly connected to the bottom end of the buffer plate 3, and the four sets of sleeve plates 5 are symmetrically fixedly connected to the upper sides of the left and right sides of the mounting frame 2. The four sets of slide rods 4 are slidably installed on the sleeve plates 5 respectively. Through the four sets of slide rods 4 symmetrically distributed at the bottom end of the buffer plate 3, when the top plate 14 is raised, the buffer plate 3 rises under the rebound action of the buffer spring 8, which plays a stable guiding role, making the buffer plate 3 less prone to shaking and improving stability.

[0021] Both sets of buffer plates 3 are fixedly connected to the top of the buffer pads 11; by setting the buffer pads 11, when the top plate 14 descends, the bottom of the top plate 14 is prevented from directly contacting the top of the buffer plate 3, thus playing a preliminary buffering role.

[0022] Each of the four sets of slide rods 4 is fixedly provided with a limiting block 12 at its bottom end; by setting the limiting block 12, when the buffer plate 3 rises due to the rebound of the buffer spring 8, the slide rod 4 can be limited to prevent the slide rod 4 from separating from the sleeve plate 5.

[0023] Sliding sleeves 15 are fixedly installed in the guide holes of both sets of mounting brackets 2; by setting the sliding sleeves 15, the guide rod 6 can slide more smoothly on the mounting bracket 2.

[0024] The present invention relates to a top-loading mechanism for a welding machine. In operation, after the top plate 14 is raised, the buffer plate 3 is initially in a raised state, with the inner sides of the two sets of guide rods 6 abutting against each other. When the piston rod in the top-loading cylinder 13 retracts, the cylinder drives the top plate 14 downwards. During this downward movement, the bottom of the top plate 14 contacts the top of the buffer plate 3 first, and as the top plate 14 moves downwards, it pushes the buffer plate 3 downwards, causing the buffer plate 3 to push the slide rod 4 downwards along the sleeve plate 5. This, in turn, causes the buffer plate 3 to pull the guide rod 6 outwards via the support rod 10, compressing the buffer spring 8. When the top cylinder 13 is fully retracted, the top plate 14 descends to its lowest position, and the buffer spring 8 is no longer compressed. The compression of the buffer spring 8 provides a buffering effect during the descent of the top plate 14.

[0025] The material-eating mechanism for a welding machine of this utility model has common mechanical installation, connection or setting methods, and can be implemented as long as it can achieve its beneficial effect. The base plate, mounting frame, material-eating cylinder and material-eating plate of this utility model are prior art disclosed in a laser welding machine with patent publication number CN218874095U. Its specific structure and working principle have been described in detail, so this application will not repeat them in detail.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
