Description

Technical Field

[0002] Laser welding machine, also often called laser welding machine, laser welding machine, is a machine used for laser welding in material processing. It mainly uses high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool.

[0003] Existing laser welding machines mainly use conical parts to overlap and extrude another set of workpieces. However, the support point at the end of the conical part is small, which makes it inconvenient to extrude and fix workpieces of other shapes. The applicability is low. In addition, when the workpiece is rotated for full welding, the end of the workpiece is prone to rotational wear with the conical part.

[0004] The reason for this problem is that, when welding, the current laser welding machine mainly fixes the tubular workpiece on the fixture on the laser welding machine and then uses the conical part to overlap and extrude another set of workpieces. Since the conical part is inserted into the inner cavity at the end of the tubular workpiece for extrusion and fixation, and the end of the conical part is relatively sharp and the support point is small, it is not convenient to extrude and fix other workpieces of different shapes, and its applicability is low. Moreover, when the fixture on the laser welding machine drives the workpiece to rotate for full welding, the workpiece will rotate on the outer surface of the conical part, which can easily cause wear on the end of the workpiece. In view of the shortcomings of the existing technology, we propose a positioning and clamping device and its laser welding equipment to solve the above problems. Utility Model Content

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] The embodiment of the present application solves the problem that the current laser welding machine mainly uses a conical part to overlap and extrude another group of workpieces, and the support point at the end of the conical part is small, which is not convenient for squeezing and fixing other workpieces of different shapes, and has low applicability. In addition, when the workpiece is rotated for full welding, the end of the workpiece is prone to rotational wear with the conical part.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] The embodiment of the utility model discloses a positioning and pressing device and laser welding equipment thereof.

[0029] According to the attached Figure 1-5 As shown, a positioning and pressing device and laser welding equipment thereof include a pressing slide 1 provided on a laser welding machine, and a pressing structure 2 is provided on the top of the pressing slide 1;

[0030] The pressing structure 2 includes a slider 21 , a rotating plate 22 , a clamp 23 and a fixing rod 25 ; the slider 21 can slide on the pressing rail 1 through a driving member such as a cylinder or a hydraulic rod.

[0031] The slider 21 is slidably connected to the top of the clamping slide rail 1, and the slider 21 is used to move the workpiece. The turn plate 22 is rotatably connected to the side wall of the slider 21. The clamp 23 is set on the side wall of the turn plate 22. The clamp 23 is used to fix the workpiece. The fixing rod 25 is slidably connected to the inside of the slider 21, and the fixing rod 25 is inserted into the end of the turn plate 22. The fixing rod 25 is used to fix the turn plate 22.

[0032] A rotating shaft 221 is fixedly connected to the side wall of the rotating plate 22 . The rotating shaft 221 is rotatably connected to the interior of the slider 21 . The fixing rod 25 is inserted into the side wall of the rotating shaft 221 .

[0033] The fixing rod 25 is in the shape of a hexagonal column.

[0034] The end of the fixed rod 25 is fixedly connected to a movable rod 251 . The movable rod 251 passes through the side wall of the slider 21 . The movable rod 251 is used to move the fixed rod 25 .

[0035] The pressing structure 2 further includes a right-angle piece 26 and a clamping rod 27;

[0036] The right-angle piece 26 is fixedly connected to the clamping rod 27. Both the right-angle piece 26 and the clamping rod 27 pass through both sides of the movable rod 251. The clamping rod 27 is clamped inside the slider 21. The clamping rod 27 is used to fix the fixed rod 25. By manually pressing the two sets of right-angle pieces 26, the clamping rod 27 can be driven to retract inside the movable rod 251. At this time, the movable rod 251 can be moved toward the rotating plate 22 until the fixed rod 25 is inserted into the side wall of the rotating shaft 221. At this time, the fixed rod 25 can fix the rotating plate 22, preventing the rotating plate 22 from rotating at will.

[0037] A spring 28 is fixedly connected between the right-angle piece 26 and the movable rod 251. The spring 28 is used to reset the right-angle piece 26. After loosening the right-angle piece 26, the elastic force of the spring 28 can reset the right-angle piece 26 and the clamping rod 27. At this time, the clamping rod 27 will be inserted into the interior of the slider 21 to fix the fixed rod 25.

[0038] The clamp 23 includes an upper clamping piece 231 and a lower clamping piece 232 , and the upper clamping piece 231 and the lower clamping piece 232 are arranged opposite to each other.

[0039] The lower clamp 232 is fixedly connected to the side wall of the rotating plate 22. The side wall of the rotating plate 22 is provided with a slide groove 222. The internal rotation of the slide groove 222 is connected to the screw rod 24. The upper clamp 231 is threadedly connected to the outer peripheral wall of the screw rod 24. By rotating the screw rod 24, the upper clamp 231 can be driven to move downward. At this time, the upper clamp 231 and the lower clamp 232 can clamp the workpiece. At the same time, the V-shaped clamp 23 can clamp both rod-shaped workpieces and plate-shaped workpieces.

[0040] When the present invention is in use, first clamp one group of workpieces on the laser welding machine, then place the other group of workpieces on the lower clamp 232, and rotate the screw rod 24 to drive the upper clamp 231 to move downward and fix the workpieces with the lower clamp 232. Secondly, the hydraulic rod can drive the slider 21 to move toward the other group of workpieces until the two groups of workpieces overlap and press tightly. At this time, the laser welding machine can be driven to weld the connection between the workpieces. After welding one side, by manually pressing the two groups of right-angle pieces 26, the clamping rod 27 can be driven to shrink inside the movable rod 251. At this time, the movable rod 251 can be moved outward until the fixed rod 25 slides out of the rotating shaft 221. Then, the clamp on the laser welding machine can be driven to drive the two groups of workpieces to rotate, and the connection between the workpieces can be fully welded.

[0041] The specific functions and operation of the laser welding machine can refer to the automatic welding machine model LY-LPF-1000.
