Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, specifically a positioning structure for laser welding. Background Technology

[0002] In the laser welding process, positioning fixtures are tools that assist in controlling position or movement and are widely used in various fields. However, existing laser welding positioning fixtures cannot effectively position and fix workpieces of different specifications. They are prone to falling off during processing. They cannot adjust the angle of the workpiece for multi-directional processing during processing and require disassembling parts to readjust the workpiece angle, which is cumbersome and inconvenient for users.

[0003] Publication No. CN216227536U discloses a positioning structure for laser welding of iron shell shaft cores. By setting a movable limiting rod and a limiting spring within the movable rod to form a nested telescopic structure, when the drive motor is turned and the adjusting rod is rotated, the movable rod moves in the opposite direction under the action of the opposite thread. This utilizes rubber pads to limit and clamp the outer walls of the iron shell and shaft core, effectively improving the stability of the device. However, this patent still has the following problems in practical use:

[0004] Although the positioning structure for laser welding of iron shell shaft cores causes the movable rod to move in opposite directions under the action of the opposite thread when the driving motor rotates the adjusting rod, thereby using the rubber pad to limit and clamp the outer wall of the iron shell and shaft core, the cooperation between the two fixed plates alone cannot clamp and fix some curved or differently shaped workpieces, thus reducing the stability of the device's clamping.

[0005] A positioning structure for laser welding is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning structure for laser welding, in order to solve the problem mentioned in the background art that when the adjusting rod is rotated by the drive motor, the moving rod will move in opposite directions under the action of the opposite thread, thereby using the rubber pad to limit and clamp the outer wall of the iron shell and the shaft core. However, the cooperation between the two fixed plates alone cannot clamp and fix some curved or differently shaped workpieces, thus reducing the stability of the device clamping.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a positioning structure for laser welding, including a clamping mechanism and a first drive motor installed on one side of the clamping mechanism;

[0008] A drive mechanism is provided above the clamping mechanism, and a second drive motor is installed on one side of the drive mechanism.

[0009] Also includes:

[0010] The clamping mechanism includes a frame, a support platform is fixedly connected to one side inside the frame, and a support plate is fixedly connected to the top of the support platform.

[0011] One side of the support plate is fixedly connected to the first drive motor. The output end of the first drive motor passes through the support plate and is fixedly connected to a bidirectional threaded rod. The end of the bidirectional threaded rod away from the first drive motor is rotatably connected to the support plate.

[0012] The two ends of the bidirectional threaded rod are symmetrically connected to threaded sleeves on the outer sides. The top ends of the two threaded sleeves are fixedly connected to clamping blocks. The clamping blocks are rotatably connected to a first semi-circular clamping block.

[0013] Preferably, the first semicircular clamping block is symmetrically rotatably connected to the inside of a second semicircular clamping block, and the second semicircular clamping block is symmetrically rotatably connected to the inside of a third semicircular clamping block.

[0014] Preferably, a fourth semicircular clamping block is symmetrically rotatably connected inside the third semicircular clamping block, and a workpiece is attached to one side of the fourth semicircular clamping block, while the bottom side of the workpiece is attached to the support plate.

[0015] Preferably, the drive mechanism includes a bracket, the top of which is fixedly connected to the frame, and one side of which is fixedly connected to the second drive motor.

[0016] Preferably, the output end of the second drive motor passes through the bracket and is fixedly connected to a roller. The end of the roller away from the second drive motor is rotatably connected to the bracket, and a groove is provided on the outer side of the roller.

[0017] Preferably, a slider is slidably connected inside the groove, one end of the slider is fixedly connected to a sliding sleeve, and a guide rod is slidably connected inside the sliding sleeve.

[0018] Preferably, both ends of the guide rod are fixedly connected to the bracket, a telescopic rod is fixedly connected to the bottom side of the sliding sleeve, and a welding device is fixedly connected to the output end of the telescopic rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this positioning structure for laser welding can clamp workpieces of different shapes by setting a clamping mechanism, and can drive the welding equipment to move by setting a driving mechanism, thus enabling welding treatment at different positions on the surface of the workpiece. The specific details are as follows:

[0020] 1. By setting up a clamping mechanism, workpieces of different shapes can be clamped. The first drive motor drives the bidirectional threaded rod to rotate. By utilizing the thread action between the bidirectional threaded rod and the threaded sleeve, the two clamping blocks move towards each other simultaneously. By utilizing the cooperation between the first semicircular clamping block, the second semicircular clamping block, the third semicircular clamping block and the fourth semicircular clamping block, workpieces of different shapes can be clamped.

[0021] 2. By setting a drive mechanism, the welding equipment can be moved, and welding can be performed on different positions on the workpiece surface. The second drive motor drives the roller to rotate, thereby moving the slider in the groove. The guide rod limits the sliding sleeve, so that the slider moves back and forth in the groove along the horizontal direction of the guide rod, thereby driving the welding equipment to move left and right in the horizontal direction, and can perform welding on different positions of the workpiece in the horizontal direction.

[0030] One side of the support plate 103 is fixedly connected to the first drive motor 104. The output end of the first drive motor 104 passes through the support plate 103 and is fixedly connected to a bidirectional threaded rod 105. The end of the bidirectional threaded rod 105 away from the first drive motor 104 is rotatably connected to the support plate 103. The bidirectional threaded rod 105 is driven to rotate by the first drive motor 104.

[0031] The outer sides of both ends of the bidirectional threaded rod 105 are symmetrically threaded with threaded sleeves 106. The top ends of the two threaded sleeves 106 are fixedly connected with clamping blocks 107. The inside of the clamping blocks 107 is rotatably connected with a first semi-circular clamping block 108. The threaded sleeves 106 are used to fix the position of the clamping blocks 107.

[0032] The first semicircular clamping block 108 is symmetrically rotatably connected to the second semicircular clamping block 109, the second semicircular clamping block 109 is symmetrically rotatably connected to the third semicircular clamping block 110, and the third semicircular clamping block 110 is symmetrically rotatably connected to the fourth semicircular clamping block 111. The workpiece 112 is attached to one side of the fourth semicircular clamping block 111, and the bottom side of the workpiece 112 is attached to the support plate 103. By utilizing the cooperation between the first semicircular clamping block 108, the second semicircular clamping block 109, the third semicircular clamping block 110, and the fourth semicircular clamping block 111, workpieces 112 of different shapes can be clamped.
