Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a positioning device for a fiber laser welding machine. Background Technique

[0002] Laser welding uses high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses into the interior of the materials through heat conduction, melting the materials to form a specific molten pool. It is a new type of welding method, mainly for welding thin-walled materials and precision parts, and can achieve spot welding, butt welding, lap welding, seal welding, etc. A fiber laser welding machine is a laser welding device that couples a high-energy laser beam into an optical fiber, transmits it over a long distance, collimates it into a parallel light through a collimating mirror, and then focuses it on the workpiece for welding.

[0003] Since most of the existing laser welding machines do not have a relatively stable clamping effect, the materials will shift during the welding process, increasing the situation of welding deviation or over-welding of the materials, reducing the working efficiency of the completed material welding. The relatively hard clamping components will increase the situation of material damage, increasing the probability of defective products during the material welding process, bringing certain adverse effects to the actual use.

[0004] As disclosed in a positioning device for a fiber laser welding machine in Chinese Patent CN214641117U, through the setting of a sliding component, the air cylinder 1 can drive the moving table to move relatively stably. Through the setting of a limiting component, the movement track of the clamping frame is limited, so that the rotation of the threaded rod can drive the clamping frame to move. Through the setting of a spring, the clamping effect of the moving plate is more stable. Through the setting of a soft pad, the situation of the moving plate being too hard and damaging the material is reduced. Through the setting of a telescopic rod, the movement of the moving plate is smoother and more stable, improving the working efficiency of the completed material welding, reducing the situation of material damage caused by the relatively hard clamping components, and reducing the probability of defective products during the material welding process, bringing convenience to the staff.

[0005] However, the positioning method of this device is relatively complex during use, affecting the welding efficiency.

[0006] Therefore, we urgently need to provide a positioning device for a fiber laser welding machine. Content of the Utility Model

[0007] The purpose of the utility model is to provide a positioning device for a fiber laser welding machine to solve the problem of relatively complex positioning method and affecting welding efficiency proposed in the above background technique.

The second electric push rod is fixedly installed on the top of the support frame, and the welding head is fixedly installed at the output end of the second electric push rod.

[0013] Preferably, the guide rods penetrate through the front and rear ends of the inside of the moving plate, and the threaded rod is threadedly connected to the inside of the moving plate.

[0028] The welding device includes a positioning unit, a clamping unit, and a welding unit. The positioning unit is arranged on the top of the workbench 1, the clamping unit is arranged on the top of the positioning unit, and the welding unit is arranged above the workbench 1.

[0029] The positioning unit includes a fixing plate 301, guide rods 302, a threaded rod 303, a handle 304, a moving plate 305, a fixing block 306, a positioning rod 307, a spring 308, and a positioning plate 309. The fixing plate 301 is fixedly installed on the left and right sides of the top of the workbench 1. A bearing is fixedly installed inside the right fixing plate 301, and the right end of the threaded rod 303 is fixedly installed on the inner ring of the bearing. The threaded rod 303 is supported by the bearing, making the rotation of the threaded rod 303 more stable. The guide rods 302 are fixedly installed at the front and rear ends of the adjacent sides of the left and right fixing plates 301. The guide rods 302 penetrate through the front and rear ends of the inside of the moving plate 305. The threaded rod 303 is threadedly connected to the inside of the moving plate 305. By rotating the handle 304 to drive the cooperation between the threaded rod 303 and the moving plate 305, the moving plate 305 can move left and right along the guide rods 302. The threaded rod 303 is installed between the front and rear two guide rods 302. The handle 304 is fixedly installed on the left side of the threaded rod 303. The moving plate 305 is installed above the workbench 1. The fixing block 306 is fixedly installed in the middle of the front of the moving plate 305. The positioning rod 307 is installed inside the fixing block 306. The lower end of the spring 308 is fixedly installed on the top of the fixing block 306 outside the positioning rod 307. The top of the spring 308 is fixedly connected to the top of the positioning rod 307. By the spring 308 providing a downward pulling force for the positioning rod 307, the positioning rod 307 is pushed to cooperate with the positioning plate 309 to position the moving position of the moving plate 305. The positioning plate 309 is fixedly installed at the front end of the top of the workbench 1. A positioning hole with the same diameter as the positioning rod 307 is opened on the upper surface of the positioning plate 309. By the cooperation of the positioning rod 307 and the positioning hole, the positioning of the position of the moving plate 305 is realized. The left and right sides of the positioning plate 309 are inclined planes.

[0030] The welding unit includes a support frame 312, a second electric push rod 313, and a welding head 314. The support frame 312 is fixedly installed at the rear end of the top of the workbench 1. The second electric push rod 313 is fixedly installed on the top of the support frame 312. By adjusting the height of the welding head 314 through the second electric push rod 313, it is convenient to weld the material. The welding head 314 is fixedly installed at the output end of the second electric push rod 313. Example 2:

[0031] On the basis of Embodiment 1: The clamping unit includes a first electric push rod 310 and a clamping plate 311.

The clamping plate 311 is fixedly installed at the output end of the first electric push rod 310. A rubber pad is installed on the side of the clamping plate 311 away from the first electric push rod 310 to prevent the clamping plate 311 from scratching the surface of the material.

[0032] During use, place the material to be welded on the top of the moving plate 305, then start the first electric push rod 310 to expand and contract so that the clamping plate 311 abuts against both sides of the material to clamp the material. Then rotate the handle 304 to drive the threaded rod 303 to rotate. When the threaded rod 303 cooperates with the moving plate 305, the moving plate 305 moves left and right along the guide rod 302, and at the same time drives the positioning rod 307 to slide. When the positioning rod 307 moves along the inclined surface of the positioning plate 309, the positioning rod 307 moves upward and stretches the spring 308. When the positioning rod 307 moves directly above the positioning hole, the spring 308 provides a downward pulling force for the positioning rod 307 to make the positioning rod 307 enter the positioning hole, thereby completing the positioning of the moving plate 305. Then stop rotating the handle 304, and then weld the material through the welding head 314.
