Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a new laser welding clamping device. Background Art

[0002] Laser welding is a welding method that uses a focused laser beam as energy to generate heat to bombard the weldment. Due to the optical properties of laser such as refraction and focusing, laser welding is very suitable for welding micro parts and parts with poor accessibility. Laser welding also has the characteristics of low heat input, small welding deformation, and no influence of electromagnetic fields. However, a clamping device is required in laser welding.

[0003] However, the prior art still has the following problems:

[0004] First, the laser welding clamping device of the prior art is not convenient for clamping multiple products at the same time. The clamping method is single, and usually only one product can be clamped at a time, which has a low clamping efficiency for the product, and the clamping position needs to be adjusted by the employees themselves, which causes certain difficulties in the operation.

[0005] Secondly, the laser welding clamping device of the prior art is not convenient for fixing and locking the jig plate. During laser welding, the product to be processed needs to be relatively stable. If the jig plate is not convenient for installation and fixing, the stability of the product during welding cannot be guaranteed, which may affect the quality of the processed product.

[0006] In view of the above problems, the inventor proposes a new laser welding clamping device to solve the above problems. Utility Model Content

[0007] In order to solve the problem that it is inconvenient to clamp multiple products at the same time and it is inconvenient to fix and lock the fixture plate; the purpose of the utility model is to provide a new laser welding clamping device.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions: a new laser welding clamping device, comprising a base, an upper end of the base is provided with an assembly welding jig plate, an upper end of the base is fixedly provided with a cylinder, an output end of the cylinder is fixedly provided with a spring preload mechanism, an upper end of the assembly welding jig plate is provided with a plurality of parts to be welded, ten parts to be welded are provided, and the ten parts to be welded are distributed at equal intervals, an installation member is provided at the upper end of the parts to be welded, four plug-in columns are fixedly provided at the lower end of the installation member, and a column groove for cooperating with the plug-in columns is provided at the upper end of the parts to be welded, a plurality of placement grooves for cooperating with the parts to be welded are provided at the upper end of the assembly welding jig plate, an insert plate is fixedly provided at the lower end of the parts to be welded, a plate groove for cooperating with the insert plate is provided at the upper end of the assembly welding jig plate, both sides of the assembly welding jig plate and both sides of one end of the insert plate are provided with fixing grooves, and the fixing grooves corresponding to the two positions are movably inserted with pins.

[0009] Preferably, fixed blocks are provided on both sides of the upper end of the base, and connecting blocks are connected to both sides of the upper end of the fixed block by bolts, one end of the fixed block is provided with a motor, the output end of the motor passes through the fixed block and is fixedly connected to a screw rod, one end of the screw rod is fixedly provided with a limiting disk, and a moving block is threadedly sleeved on the outer surface of the screw rod, one end of the fixed block is provided with a groove, one end of the screw rod is rotatably connected to an inner wall of one side of the groove, the outer surface of the moving block is fitted with the inner wall of the groove, and a fixing column is fixedly provided at the inner end of the moving block, and a sliding bar is fixedly provided at one end of the moving block, and a sliding groove for cooperating with the sliding bar is provided on the inner wall of one side of the groove, and locking grooves for cooperating with the fixing column are provided on both sides of one end of the assembly welding jig plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model assembles a welding jig plate. Under the action of the parts to be welded and the plug plate, multiple parts to be welded can be placed on the assembled welding jig plate. In this way, laser welding can be performed on multiple workpieces at the same time, which is highly efficient. The mounting parts on the parts to be welded can be equipped with welding structures. The parts to be welded are placed in the placement slots, inserted into the plate slots through the plug plates, and then the plug pins are inserted into the fixing slots to complete the installation. The installation of the parts to be welded is simple and convenient, and has strong firmness. The cooperation of the plug column and the column slot makes it easy to install the mounting parts, and the installation is relatively firm. Ten equidistantly distributed parts to be welded make it possible to weld more workpieces at one time. The product assembly is directly placed on the jig. After the assembly is completed, it is directly placed on the welding mechanism module for laser welding. The welding position is fixed each time to ensure quality and efficiency, reduce multiple turnovers, and reduce the efficiency loss caused by clamping. Multiple products can be clamped for laser welding, which reduces the position adjustment of employees after clamping, improves the work efficiency and quality, and can clamp multiple products at the same time, thereby achieving a high welding processing efficiency.

[0012] 2. The utility model fixes the jig plate through the fixed block, under the action of the screw rod and the moving block therein, and starts the motor to rotate the screw rod, thereby driving the moving block to move. The movement of the moving block drives the fixed column to move until the fixed column is inserted into the locking groove on the assembled welding jig plate to complete the fixation. The fixation is convenient and has a good fixing effect, thereby improving the subsequent laser welding process quality. The moving range of the moving block is limited by the limiting disk, and the movement of the moving block is made more stable by the groove. The cooperation of the slide bar and the slide groove improves the moving effect of the moving block, enhances the stability of the clamped welding plate, and can conveniently fix and lock the jig plate, thereby achieving a better welding effect.
