DETAILED DESCRIPTION

[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments.

[0020] Referring to Figures 1-5 A kind of laser welding device for precision metal piece processing, comprising: bottom plate 1, the top of bottom plate 1 is fixedly installed with box 3, the inside of box 3 is rotatably installed with rotating rod 11, the outside of rotating rod 11 is fixedly installed with bevel gear one 12, the top of box 3 is slidably installed with two groups of inclined block one 9, the top of two groups of inclined block one 9 is fixedly installed with moving plate 10, the side of two groups of moving plate 10 is fixedly installed with annular base 19, the inside of two groups of annular base 19 is rotatably installed with annular ring 18, the side of two groups of annular ring 18 is fixedly installed with fixed plate 20, the side of two groups of inclined block one 9 adjacent inclined surface is abutted with inclined block two 16, the bottom of inclined block two 16 is fixedly installed with threaded sleeve 15, the inside of threaded sleeve 15 is threadedly connected with screw rod 14, the bottom of screw rod 14 is fixedly installed with bevel gear two 13, the top of bottom plate 1 is fixedly installed with four groups of support column 4, the top of four groups of support column 4 is fixedly installed with top plate 5, the top of top plate 5 is fixedly installed with electric push rod 6, the output end of electric push rod 6 is fixedly installed with laser welding head 7.

[0021] In the embodiment, the side of one group of moving plate 10 is fixedly installed with motor two 17, one group of fixed plate 20 is fixedly installed on the output end of motor two 17, the side of box 3 is fixedly installed with motor one 8, rotating rod 11 is fixedly installed on the output end of motor one 8, the inside of two groups of annular base 19 is provided with rotating rail, two groups of annular ring 18 are rotatably installed in corresponding rotating rail, and the synchronous rotation mechanism can ensure that the relative position accuracy of precision metal piece is maintained during welding process.

[0022] In the embodiment, the top of box 3 is provided with sliding rail, and two groups of inclined block one 9 are slidably installed in the sliding rail.

[0023] In the embodiment, the side of two groups of clamping plates 21 is provided with anti-skid lines, bevel gear one 12 and bevel gear two 13 are engaged, and the anti-skid lines can greatly increase the friction between clamping plate 21 and metal piece. During welding process, metal piece can be impacted by laser, gravity and various vibrations, and the anti-skid lines can effectively prevent metal piece from sliding or rotating between clamping plates 21.

[0024] In the embodiment, the bottom of bottom plate 1 is fixedly installed with four groups of supporting legs 2, the bottom of four groups of supporting legs 2 is fixedly installed with anti-skid pad, and the four groups of supporting legs 2 are evenly distributed to effectively disperse the weight of the device and prevent the device from falling due to unstable center of gravity.

[0025] In this embodiment, the two sides of the inclined block two 16 are provided with grooves, and the two groups of inclined block one 9 are slidingly installed in the corresponding grooves. The grooves on the two sides of the inclined block two 16 provide precise sliding paths for the inclined block one 9, ensuring that the inclined block one 9 moves linearly along the predetermined inclined surface direction. This precise linear motion is crucial during the operation of the clamping mechanism of the laser welding device.

[0026] In this embodiment, when in use, the precision metal parts are placed in the clamps, and the rotating rod 11 is driven to rotate in the box 3 by starting the motor two 17, thereby driving the bevel gear one 12 to rotate. Through the meshing between the bevel gear one 12 and the bevel gear two 13, the bevel gear two 13 is driven to rotate, thereby driving the screw rod 14 to rotate. Through the cooperation between the screw rod 14 and the threaded sleeve 15, the threaded sleeve 15 and the inclined block two 16 are driven to move up and down, thereby relatively approaching or moving away from the two groups of moving blocks one in the slide rails of the box 3. Then, through the relative movement of the moving plate 10, the annular rotating ring 18, the annular base 19, the fixed plate 20 and the clamping plate 21 are driven to move relatively, thereby stably clamping and fixing different sizes of precision metal parts and quickly releasing the fixation. The transmission between the bevel gear one 12 and the bevel gear two 13 has high precision, which can realize accurate angle and speed control. This makes the rotation of the screw rod 14 able to be accurately adjusted according to actual needs, and different sizes of precision metal parts can be clamped and fixed. Therefore, the laser welding device can be suitable for processing precision metal parts of various specifications, without the need to equip different clamps for different sizes of workpieces, greatly improving the universality of the equipment. Whether it is a small precision electronic component or a large mechanical part, it can be welded on the same equipment, reducing the enterprise's equipment investment cost.

[0027] By fixing the precision metal parts with the clamping plate 21, the fixed plate 20 and the clamping plate 21 are driven to rotate by starting the motor, and the other group of fixed plate 20 and clamping plate 21 are driven to rotate synchronously by the abutting precision metal parts, thereby driving the annular rotating ring 18 to rotate in the annular rotating track of the annular base 19. This makes the precision metal parts rotate more stably during laser welding, and the laser welding head 7 is adjusted in the up-down position by starting the electric push rod 6, thereby welding the precision metal parts. Without moving or rotating the welding head, the precision metal parts can be welded. This synchronous rotation mechanism can ensure the accuracy of the relative position of the precision metal parts during welding. For precision metal parts, any slight displacement or angle deviation may cause the welding quality to decrease. This synchronous rotation method can effectively avoid welding defects caused by asynchronous rotation, such as uneven welds and welding point deviation, thereby ensuring the welding precision.

[0028] The above has carried out the detailed introduction to the laser welding device for the precision metal piece processing provided by the utility model. The principle and implementation mode of the utility model are described in the paper by applying specific embodiments, and the above embodiment description is only used for helping to understand the method and core idea of the utility model. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claim.
