Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to an automotive key welding machine with a positioning structure. Background Technology

[0002] In the automotive manufacturing and repair industry, the welding quality of car keys directly affects their performance and security. Traditional car key welding machines have several shortcomings in the welding process. On the one hand, the replenishment of welding wire often relies on manual operation. When the welding wire in the machine runs out, it needs to be manually replaced, leading to frequent interruptions in welding operations, greatly reducing production efficiency. Furthermore, manual operation is prone to problems such as untimely replenishment and improper installation, affecting welding quality. On the other hand, existing welding machines have a relatively simple positioning structure for car keys, making it difficult to adapt to different models, sizes, and thicknesses of car keys. The fixing effect is poor, and the key is prone to displacement during welding, resulting in welding position deviations and a high scrap rate. Therefore, there is an urgent need to develop a car key welding machine that can automatically replenish welding wire and has an efficient positioning structure to meet production requirements.

[0003] While existing technologies can achieve certain welding effects, they suffer from drawbacks such as a lack of efficient automatic material replenishment and adaptive positioning capabilities for multi-specification workpieces. In view of this, we propose an automotive key welding machine with a positioning structure, which solves the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a car key welding machine with a positioning structure.

[0005] The technical solution of this utility model is as follows: A car key welding machine with a positioning structure includes a mounting frame and a welding machine assembly. The mounting frame houses the welding machine assembly, and a mounting plate is fixedly connected to one side of the welding machine assembly. The mounting plate is provided with a first guide rail, and multiple welding wires are arranged in the first guide rail. The mounting plate is provided with a movable frame, and one end of the outer wall of the movable frame is fixedly connected to one end of a first spring. The other end of the first spring is fixedly connected to one side of the outer wall of the mounting plate. The first guide rail is the movement track of the welding wire when the welding machine assembly replenishes welding wires. The first spring is always in a stretched state and continuously releases elastic tension.

[0006] When using a car key welding machine with a positioning structure as described in this solution, according to the size of the car key to be welded, the threaded rod is rotated to move the moving plate along the second guide rail, the pressure plate is raised, the car key is placed between the pressure plate and the moving block, the pressure plate is released, and the second spring causes the pressure plate to reset and fix the car key; the welding machine assembly welds the car key, and when the welding wire in the welding machine assembly is consumed and the welding wire is replaced, after the welding wire installation slot in the welding machine assembly is opened, under the thrust of the first spring, the moving frame pushes the welding wire along the first guide rail into the welding wire installation slot to complete the automatic replenishment of the welding wire.

[0007] Preferably, the movable frame penetrates one side of the outer wall of the mounting plate, with one end of the movable frame located on the side of the welding wire and the other end located on the outside of the mounting plate. Under the tension of the first spring, the movable frame maintains the potential energy to move inward into the mounting plate, causing one side of the movable frame to squeeze the welding wire. When the welding wire passage of the welding machine assembly is opened, the welding wire can be automatically replenished.

[0008] Preferably, the lower end of the mounting bracket is fixedly connected to the upper outer wall of the workbench, and the lower end of the workbench is provided with multiple brackets. The workbench is used to fix the car key.

[0009] Preferably, two symmetrical fixing plates are fixedly connected to the upper outer wall of the worktable. The fixing plates are provided with threaded rods that penetrate the fixing plates. The fixing plates are provided with threads, and the threads of the fixing plates engage with the threads of the threaded rods.

[0010] Preferably, one end of the threaded rod is connected to the movable block via a bearing, and the movable block is provided with two limiting rods that pass through the fixed plate to prevent the movable block from shifting during movement.

[0011] Preferably, the upper outer wall of the worktable is provided with a plurality of second guide rails, the second guide rails are connected to the lower end of the moving block, and the moving block moves along the trajectory of the second guide rails without disengaging, thus preventing excessive movement.

[0012] Preferably, the upper outer wall of the movable block is provided with two symmetrical connecting rods, the upper outer wall of the connecting rod is fixedly connected with a fixing ring, the connecting rod is provided with a pressure plate, and the car key to be welded is fixed between the pressure plate and the movable block.

[0013] Preferably, the lower outer wall of the fixing ring is fixedly connected to the upper end of the second spring, and the lower end of the second spring is fixedly connected to the upper outer wall of the pressure plate. When fixing the car key, the second spring continuously releases elastic tension downwards to achieve a fixing effect that adapts to car keys of different thicknesses.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model utilizes a first spring that is always under tension. The continuously released elastic force of this spring pulls a moving frame, which in turn moves the welding wire within the guide rail. When the welding wire passage of the welding machine assembly is open, the welding wire is automatically replenished to the assembly without manual operation, achieving an automatic wire replenishment function. This design significantly improves welding efficiency, reduces downtime during welding, and makes welding operations more continuous and efficient.

[0016] II. Based on the first beneficial effect, this utility model adjusts the position of the moving block by rotating the threaded rod, and ensures the linear motion accuracy of the moving block in conjunction with the guide rail and limit rod, thus achieving positioning adjustment for car keys of different sizes. Simultaneously, the car key is clamped between the pressure plate and the moving block by the elastic tension of a spring. The elasticity of the spring can adapt to car keys of different thicknesses, ensuring reliable fixing of different models of car keys. This adaptive positioning and clamping structure allows the welding machine to be used for welding various models of car keys, improving the versatility and applicability of the equipment and reducing the equipment procurement costs for enterprises.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1-4 As shown, this embodiment is a car key welding machine with a positioning structure, including a mounting frame 1 and a welding machine assembly 2. The mounting frame 1 houses the welding machine assembly 2, and a mounting plate 5 is fixedly connected to one side of the welding machine assembly 2. The mounting plate 5 has a first guide rail 8, and multiple welding wires 3 are arranged in the first guide rail 8. The mounting plate 5 has a movable frame 6, one end of which is fixedly connected to one end of a first spring 7, and the other end of the first spring 7 is fixedly connected to one side of the outer wall of the mounting plate 5. In use, the first guide rail 8 serves as the movement track for the welding wires 3 when the welding machine assembly 2 needs to replenish them. The first spring 7 is always in a stretched state, continuously releasing elastic tension. When the welding machine assembly 2 needs to replenish the welding wires 3, the elastic tension of the first spring 7 pulls the movable frame 6, causing the movable frame 6 to push the welding wires 3 to move within the first guide rail 8, thereby achieving automatic replenishment of the welding wires 3 without manual operation, improving welding efficiency. The welding machine assembly 2 in this device has a series of built-in electric welding structures, mainly for energizing the welding wires 3 to achieve welding. The specific structure is not described further as it does not involve innovative parts.

[0030] Example 2

[0031] Please see Figures 1-4As shown, this embodiment, based on embodiment 1, further includes: a movable frame 6 penetrating one side of the outer wall of the mounting plate 5, with one end of the movable frame 6 located on one side of the welding wire 3 and the other end located on the outside of the mounting plate 5. During use, under the tension of the first spring 7, the movable frame 6 maintains a tendency to move inwards towards the mounting plate 5, ensuring that one side of the movable frame 6 constantly presses against the welding wire 3. When the welding wire 3 passage of the welding machine assembly 2 is opened, under the action of the first spring 7, the welding wire 3 can automatically move along the first guide rail 8 towards the welding machine assembly 2, ensuring timely replenishment of the welding wire 3 and guaranteeing the continuity of the welding process.

[0032] The lower end of the mounting bracket 1 is fixedly connected to the upper outer wall of the worktable 4. Multiple supports 9 are provided at the lower end of the worktable 4. During use, the worktable 4 is used to hold the car key to be welded, and the supports 9 support the worktable 4, making the entire welding machine structure more stable. By fixing the mounting bracket 1 to the worktable 4, the relative position between the welding machine assembly 2 and the worktable 4 is ensured to be stable, thereby improving the welding accuracy and stability.

[0033] Two symmetrical fixed plates 16 are fixedly connected to the upper outer wall of the workbench 4. Each fixed plate 16 has a threaded rod 15 that passes through it. During use, the threads within the fixed plate 16 engage with the threads of the threaded rod 15. Rotating the threaded rod 15 allows it to move linearly within the fixed plate 16. By rotating the threaded rod 15, the position of the moving block 13 can be adjusted to accommodate different sizes of car keys, enabling the positioning and clamping of car keys of various specifications.

[0034] One end of the threaded rod 15 is connected to the movable block 13 via a bearing. The movable block 13 is provided with two limiting rods 14, which pass through the fixed plate 16. In use, the limiting rods 14 pass through the fixed plate 16. When the threaded rod 15 rotates and drives the movable block 13 to move, the limiting rods 14 can prevent the movable block 13 from shifting or rotating, ensuring that the movable block 13 moves in a straight line along the direction of the second guide rail 11, thereby improving the accuracy of positioning.

[0035] The upper outer wall of the worktable 4 is provided with multiple second guide rails 11. The second guide rails 11 are connected to the lower end of the moving block 13. In use, the lower end of the moving block 13 is connected to the second guide rails 11, so that the moving block 13 can move along the trajectory of the second guide rails 11 during the movement process, avoiding excessive movement of the moving block 13 and ensuring the movement stability and positioning accuracy of the moving block 13.

[0036] The upper outer wall of the movable block 13 is provided with two symmetrical connecting rods. A fixing ring 10 is fixedly connected to the upper outer wall of the connecting rod. The connecting rod is provided with a pressure plate 17. In use, the pressure plate 17 can move up and down on the connecting rod. The car key to be welded is placed between the pressure plate 17 and the movable block 13. Through the cooperation of the pressure plate 17 and the movable block 13, the car key can be effectively clamped and positioned to prevent the car key from moving during the welding process and ensure the welding quality.

[0037] The lower outer wall of the retaining ring 10 is fixedly connected to the upper end of the second spring 12, and the lower end of the second spring 12 is fixedly connected to the upper outer wall of the pressure plate 17. In use, when the second spring 12 is fixing the car key, it continuously releases elastic tension downwards, so that the pressure plate 17 can press tightly onto the car key. Due to the elastic effect of the second spring 12, the device can adapt to car keys of different thicknesses, realize reliable fixing of car keys of different thicknesses, and improve the versatility and applicability of the device.

[0038] Instructions for use: When using this device, according to the size of the car key to be welded, rotate the threaded rod 15 to move the moving plate along the second guide rail 11, raise the pressure plate 17, place the car key between the pressure plate 17 and the moving block 13, release the pressure plate 17, and the second spring 12 will reset the pressure plate 17 to fix the car key; the welding machine assembly 2 welds the car key. When the welding wire 3 in the welding machine assembly 2 is consumed and the welding wire 3 is replaced, after the welding wire 3 mounting slot in the welding machine assembly 2 is opened, under the push of the first spring 7, the moving frame 6 pushes the welding wire 3 along the first guide rail 8 into the welding wire 3 mounting slot to complete the automatic replenishment of the welding wire 3.

[0039] 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.
