Description

Technical Field

[0001] This utility model relates to the field of laser welding machines, specifically a laser welding machine that is easy to adjust in angle. Background Technology

[0002] Laser welding machines, also known as laser welders or laser arc welding machines, are machines used for laser material processing. Laser welding utilizes high-energy laser pulses to locally heat a small area of ​​material. The energy of the laser radiation diffuses into the material through heat conduction, melting the material to form a specific molten pool. It is a new type of welding method, mainly used for welding thin-walled materials and precision parts.

[0003] Utility model patent CN213351191U discloses a laser welding machine with an easily adjustable welding angle. This utility model relates to the field of laser welding machine technology. The laser welding machine with an easily adjustable welding angle includes a large box, a small box, a laser, and an operating table. The small box is fixed below the front surface of the large box, and the operating table is located directly above the small box. The laser is located directly above the operating table. A column is welded to the upper surface of the large box, and a connecting rod is fixedly connected to the upper end of the column. The laser is fixed to the front end of the connecting rod. A rotating shaft is rotatably connected inside the small box.

[0004] This utility model allows the operating table to rotate freely in the horizontal direction through the cooperation of a handle, turntable, rotating rod, first bevel gear, second bevel gear, and rotating shaft, making it convenient to adjust the horizontal angle of the workpiece welding. However, when the operating table is clamped, the side facing the operating table cannot be reached even if the angle is adjusted, which makes it less effective for circumferential welding of parts. In addition, after the angle is adjusted, the double-ended studs need to be tightened manually, which adds cumbersome operation steps and makes the entire angle adjustment process not particularly convenient. Utility Model Content

[0005] In view of the technical problems in the prior art, the present invention provides a laser welding machine that is easy to adjust the angle, and the purpose is to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A laser welding machine with adjustable angle includes a welding machine base. A laser welder is provided on the left side of the upper side of the welding machine base. A support platform is provided laterally on the upper side of the welding machine base corresponding to the laser welder. The support platform can retract downward into the welding machine base. Clamping blocks are symmetrically provided on the left and right sides of the upper side of the welding machine base on the support platform. A fixing block is provided on the upper side of the welding machine base corresponding to the two clamping blocks. A rotating shaft is fixed on the opposite side of the two clamping blocks, inserted into the corresponding fixing block and rotatably connected to it. A telescopic structure for driving the lateral movement of the fixing block is also provided in the left clamping block. A motor for driving the right fixing block to rotate is provided on the upper side of the welding machine base corresponding to the right fixing block.

[0008] Preferably, the telescopic structure includes a sliding rod disposed within a transverse rotation shaft. One end of the sliding rod facing the clamping block is fixedly connected to the clamping block. The sliding rod can drive the clamping block to slide laterally within the rotation shaft. A drive rod is provided laterally on the left side of the rotation shaft corresponding to the sliding rod. The right side of the drive rod passes through the rotation shaft and is threadedly connected to the sliding rod. The drive rod is rotatably connected to the rotation shaft.

[0009] Preferably, a limiting groove is provided on the upper and lower sides of the sliding connection of the sliding rod inside the rotating shaft, and a limiting slider that can slide laterally inside is provided on the upper and lower sides of the sliding rod corresponding to the limiting groove.

[0010] Preferably, the upper side of the welding machine base is provided with a groove for longitudinal movement at the support platform, and an electric push rod for driving longitudinal movement is provided at the bottom of the groove at the center of the support platform.

[0011] Preferably, the top of the left and right side walls of the groove is provided with a limiting block corresponding to the support platform. When the support platform rises to the left and right sides and abuts against the limiting block, the upper side of the support platform and the upper side of the welding machine base are on the same horizontal plane.

[0012] Preferably, a dust suction pipe is provided on the side wall of the corresponding groove inside the welding machine base, and the dust suction pipe passes through the welding machine base and is connected to an external dust collection device.

[0013] Preferably, a protective cover is provided on the welding machine base corresponding to the motor.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model provides a laser welding machine that facilitates angle adjustment. By placing the workpiece to be welded on a support platform, manually rotating the drive rod until the sliding rod moves the clamping block closer to the workpiece, and clamping it with the right-side clamping block, the support platform is retracted into the groove by an electric push rod. The laser welder then performs welding on the workpiece. When angle adjustment is required, the workpiece angle can be flipped by controlling the motor to rotate a certain angle. Without the interference of the support platform, the workpiece can be rotated 360°, allowing for multi-angle ring welding. It is easy to adjust and has wide applicability.

[0016] Meanwhile, the groove is equipped with a suction pipe that connects to external vacuuming equipment, which can adsorb the exhaust gas and waste generated during welding, ensuring a good working environment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3This application proposes a laser welding machine with easy angle adjustment, including a welding machine base 1. A laser welder 11 is provided on the left side of the upper side of the welding machine base 1. A support platform 2 is provided laterally on the upper side of the welding machine base 1 corresponding to the laser welder 11. The support platform 2 can be retracted downward into the welding machine base 1. Clamping blocks 3 are symmetrically provided on the left and right sides of the upper side of the welding machine base 1 on the support platform 2. Fixing blocks 12 are provided on the upper side of the welding machine base 1 corresponding to the two clamping blocks 3. A rotating shaft 31 is fixed on the opposite side of the two clamping blocks 3, inserted into the corresponding fixing block 12 and rotatably connected to it. A telescopic structure 4 for driving the fixing block 12 to move laterally is also provided in the left clamping block 3. A motor 5 for driving the right fixing block 12 is provided on the upper side of the welding machine base 1 corresponding to the right fixing block 12. A protective cover 8 is provided on the welding machine base 1 corresponding to the motor 5 to protect the motor 5.

[0023] Specifically, during welding, the workpiece to be welded is first placed on the support platform 2. The telescopic structure 4 inside the rotating shaft 31 of the left clamping block 3 drives the corresponding clamping block 3 to move to the right, cooperating with the right clamping block 3 to clamp the workpiece to be welded. After clamping, the support platform 2 is retracted into the welding machine base 1. When the angle needs to be adjusted, the support platform 2 is avoided from obstructing the work. When the angle needs to be adjusted, the rotation of the motor 5 drives the rotating shaft 31 of the right clamping block 3 to rotate, cooperating with the rotating shaft 31 of the left clamping block to rotate the clamped workpiece. Since there is no obstruction from the support platform 2, 360° angle rotation can be performed, which is convenient for adjustment and has wide applicability.

[0024] Meanwhile, the starting of motor 5 and the lifting of support platform 2 can be controlled by external control equipment, thereby achieving more precise angle adjustment. This control and drive method is also a commonly used control method in existing technology, and will not be elaborated here.

[0025] Further details can be found here. Figure 1-3 The telescopic structure 4 includes a sliding rod 41 disposed in the transverse rotation shaft 31. The end of the sliding rod 41 facing the clamping block 3 is fixedly connected to the clamping block 3. The sliding rod 41 can drive the clamping block 3 to slide laterally within the rotation shaft 31. A drive rod 42 is provided laterally on the left side of the rotation shaft 31 corresponding to the sliding rod 41. The right side of the drive rod 42 passes through the rotation shaft 31 and is threadedly connected to the sliding rod 41. The drive rod 42 is rotatably connected to the rotation shaft 31.

[0026] By rotating the drive rod 42, the sliding rod 41, which is threaded to it, moves laterally within the rotating shaft 31, thereby driving the clamping block 3, which is fixedly connected to the sliding rod 41, to move laterally. This facilitates the clamping and release of the workpiece and can also clamp workpieces of various sizes. As is well known, the threaded connection has a self-locking function, which prevents the clamping from loosening when adjusting the angle of the workpiece.

[0027] Meanwhile, limit grooves 43 are provided on the upper and lower sides of the sliding connection of the sliding rod 41 inside the rotating shaft 31. Limit sliders 44 that can slide laterally are provided on the upper and lower sides of the sliding rod 41 corresponding to the limit grooves 43. When the sliding rod 41 moves laterally, the limit sliders 44 are provided to prevent it from rotating and being unable to move laterally. Furthermore, the rotation of the rotating shaft 31 can be manually restricted when clamping or unclamping, which facilitates adjustment.

[0028] In order to make the rotation of the rotating shaft 31 smoother, a ball bearing can be added at the rotatable connection between the rotating shaft 31 and the fixed block 12.

[0029] Further details can be found here. Figure 1-2 The upper side of the welding machine base 1 is provided with a groove 13 for longitudinal movement of the support platform 2. The bottom of the groove 13 is provided with an electric push rod 6 for driving longitudinal movement of the support platform 2. The top of the left and right side walls of the groove 13 is provided with a limit block 14 corresponding to the support platform 2. When the support platform 2 rises to the left and right sides and abuts against the limit block 14, the upper side of the support platform 2 and the upper side of the welding machine base 1 are on the same horizontal plane, so that the workpiece placed on the support platform 2 can be clamped by the clamping block 3.

[0030] Meanwhile, a dust suction pipe 7 is provided on the side wall of the groove 13 inside the welding machine base 1. The dust suction pipe 7 passes through the welding machine base 1 and is connected to an external dust suction device (a conventional dust suction component in the prior art). It can adsorb the exhaust gas and waste generated during welding to ensure a good working environment.
