Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, and in particular to a fixture structure for a fiber laser welding machine. Background Technology

[0002] Laser welding machines, also known as laser welding machines or laser welding machines, are machines used for laser material processing. According to their working method, they are divided into laser mold welding machines, automatic laser welding machines, laser spot welding machines, and fiber optic transmission laser welding machines. During welding, clamps are used to hold and fix the workpiece before welding.

[0003] The fixture structure of most existing fiber laser welding machines does not allow for the flipping and rotation of the clamped workpiece, making it inconvenient to weld at different angles and positions. Furthermore, the need for multiple installations and disassemblies makes processing inconvenient and reduces work efficiency.

[0004] Therefore, those skilled in the art have provided a fixture structure for a fiber laser welding machine to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a clamping structure for a fiber laser welding machine. This device can flip and adjust the clamped workpiece to be in front of the operator, allowing the operator to weld the back of the workpiece without moving. It can also clamp, fix, and disassemble the workpiece to be welded, aligning the workpieces and facilitating welding for the operator, thus improving its practicality and convenience.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixture structure for a fiber laser welding machine, comprising a base, a rotating shaft rotatably disposed at the upper center of the base, a first motor fixedly disposed at the inner center of the base, a disc fixedly disposed at the upper end of the rotating shaft, first fixing blocks fixedly disposed on both sides of the middle of the disc, a connecting rod rotatably disposed between the two first fixing blocks with one end extending out of the first fixing block, a rotating block fixedly disposed on the outer wall of the connecting rod, a gear fixedly connected to the extended end of the connecting rod, and a U-shaped groove fixedly disposed at the upper end of the disc and located below the gear;

[0007] The rotating block is fixedly connected to the front end of the mounting block. The mounting block has a groove in the middle of its front end. A lead screw is rotatably installed inside the groove. A second motor is fixedly installed on one side inside the mounting block. The output end of the second motor is fixedly connected to the end of the lead screw. Slider blocks are threaded on the outer walls of both sides of the lead screw. Mounting plates are fixedly installed at the front ends of the two sliders. Fixing plates are fixedly installed at the middle of the front ends of the two mounting plates. Connecting strips are slidably installed inside the two fixing plates. Clamping plates are fixedly connected to the upper ends of the two connecting strips.

[0008] Furthermore, the output end of the first motor is fixedly connected to the end of the rotating shaft;

[0009] Through the above technical solution, the first motor drives the rotating shaft to rotate, thereby driving the disc to rotate, which in turn rotates the workpiece, making it easier for the operator to weld it.

[0010] Furthermore, a sliding rod is fixedly installed at the upper end of the U-shaped groove, and a movable sleeve is fitted on the outer wall of the sliding rod. A first electric push rod is fixedly installed on one side of the lower end of the U-shaped groove, and the output end of the first electric push rod is fixedly connected to one side of the movable sleeve. A rack is fixedly installed at the upper end of the movable sleeve.

[0011] The above technical solution involves using a first electric push rod to move the movable sleeve inside the U-shaped groove, which in turn moves the rack.

[0012] Furthermore, the rack and gear are meshed together;

[0013] The above technical solution involves moving the rack and pinion, which in turn drives the gear to rotate, thereby achieving the flipping of the workpiece.

[0014] Furthermore, the two sliders slide within the groove in a limited manner;

[0015] The above technical solution allows the slider to slide inside the groove, thereby achieving the limiting function.

[0016] Furthermore, a vertical plate is fixedly installed above the front end of each of the two mounting plates;

[0017] The above technical solution provides a vertical plate and a clamping plate for clamping and fixing the workpiece to be welded.

[0018] Furthermore, a rotating plate is rotatably provided at the lower end of the two connecting strips, a rotating seat is rotatably provided at the lower end of the two rotating plates, a second fixing block is fixedly provided on one side below the front end of the two mounting plates, a second electric push rod is fixedly provided inside the two second fixing blocks, and the output end of the two second electric push rods is fixedly connected to the front end of the rotating seat.

[0019] The above technical solution uses a second electric push rod to rotate the rotating plate, thereby moving the connecting strip and causing the clamping plate to move, thus clamping and fixing the workpiece to be welded.

[0020] This utility model has the following beneficial effects:

[0021] 1. The present invention proposes a clamping structure for a fiber laser welding machine. The first electric push rod drives the movable sleeve to move, thereby driving the rack to move, causing the gear to rotate, which in turn drives the mounting block to rotate, thus flipping the clamped workpiece. At the same time, under the action of the first motor, the flipped workpiece can be adjusted to the operator's face, so that the operator can weld the back of the workpiece without moving, thereby improving its functionality.

[0022] 2. The fixture structure of the fiber laser welding machine proposed in this utility model drives the rotating plate to rotate through the operation of the second electric push rod, thereby driving the connecting bar to move, which in turn drives the clamping plate to move. Under the action of the fixing plate, the welding workpiece can be clamped, fixed and disassembled. At the same time, with the cooperation of the lead screw, the clamping mechanisms on both sides can move relative to each other, which can align the workpieces on the clamping mechanisms on both sides, making it easier for the operator to weld the workpieces and improving its practicality and convenience.
