Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a laser welding device that facilitates workpiece positioning. Background Technology

[0002] With the rapid development of modern manufacturing, laser welding has been widely used in many fields such as automobile manufacturing, electronics, and aerospace due to its advantages of high precision, high efficiency, and non-contact operation. However, existing laser welding devices have some unsatisfactory usage in terms of workpiece positioning. Traditional positioning structures have poor versatility and are difficult to adapt to the precise positioning requirements of workpieces of different shapes and sizes, which is very inconvenient, resulting in low welding efficiency and easy welding deviation. In order to solve the above problems, the inventor proposes a laser welding device that facilitates workpiece positioning. Utility Model Content

[0003] To solve the above technical problems, the present invention adopts the following technical solution: a laser welding device for easy workpiece positioning, comprising a worktable, a V-shaped seat fixedly installed at the top of the worktable, a support frame fixedly installed at the top of the V-shaped seat, a laser welding machine fixedly installed at the top of the support frame, a support plate fixedly installed on the top surface of the worktable, symmetrically distributed strip grooves opened on the inner side of the support plate, a lead screw rotatably installed on the inner side of each strip groove, a moving block threaded on the outer side of each lead screw, a fixed block fixedly connected to the top of each moving block, a fixed plate fixedly connected to the top of each fixed block, a cylindrical block fixedly installed at one end of each fixed plate, a clamping element rotatably connected to one end of each cylindrical block, a clamping plate fixedly connected to one end of each clamping element, and symmetrically distributed springs fixedly installed at one end of each clamping plate, with one end of each spring fixedly connected to the fixed plate.

[0004] Preferably, a rotating shaft is rotatably mounted on the inner side of the support frame, a fan is fixedly connected to the outer side of the rotating shaft, a sector gear is fixedly connected to one end of the fan, a forward and reverse motor is fixedly mounted to one end of the support frame, a full gear is fixedly connected to the drive end of the forward and reverse motor, and the full gear meshes with the sector gear.

[0005] Preferably, one end of the support plate is fixedly mounted with symmetrically distributed synchronous motors, the drive end of the synchronous motors is fixedly connected to the corresponding lead screws, and one end of each synchronous motor is fixedly mounted with a synchronization chip.

[0006] Preferably, a guide plate is fixedly installed on the inner side of each of the strip grooves, and one end of the moving block is slidably sleeved on the outer side of the guide plate.

[0008] Preferably, the workbench is fixedly equipped with symmetrically distributed handles on its side.

[0009] Preferably, an integrated controller is fixedly installed on one side of the top of the V-shaped seat.

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

[0011] 1. The lead screw is controlled by a synchronous motor. The rotation of the lead screw drives the moving block to move, which in turn drives the fixed block and the fixed plate to move. The fixed plate then pushes the clamping plate to move. The clamping plate, together with the V-angle of the V-shaped seat, clamps and positions the workpiece. The clamping device rotates on the cylinder block, and the spring effect enhances the clamping force. The triangular positioning formed by the clamping plate and the V-shaped seat makes it easy to position and process workpieces of different shapes, improving versatility and convenience.

[0012] 2. By starting the fan to dissipate heat from the workpiece during welding, and in conjunction with the forward and reverse motors controlling the reciprocating rotation of the full gear, the full gear drives the sector gear to reciprocate, thereby causing the rotating shaft to drive the fan to reciprocate to expand the heat dissipation area, thus effectively dissipating heat evenly from the workpiece, preventing excessively high temperatures during welding that could lead to deformation, and thus improving the yield rate.

[0018] 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.

[0019] Example: Figure 1-3 As shown, this utility model provides a technical solution: a laser welding device for easy workpiece positioning, including a worktable 1, a V-shaped seat 11 fixedly installed at the top of the worktable 1, a support frame 12 fixedly installed at the top of the V-shaped seat 11, a laser welding machine 13 fixedly installed at the top of the support frame 12, a support plate 14 fixedly installed on the top surface of the worktable 1, symmetrically distributed strip grooves 15 opened on the inner side of the support plate 14, a lead screw 16 rotatably installed on the inner side of each strip groove 15, a moving block 17 threaded on the outer side of each lead screw 16, a fixed block 18 fixedly connected to the top of each moving block 17, a fixed plate 19 fixedly connected to the top of each fixed block 18, a cylindrical block 20 fixedly installed at one end of each fixed plate 19, a clamping piece 21 rotatably connected to one end of each cylindrical block 20, a clamping plate 22 fixedly connected to one end of each clamping piece 21, and symmetrically distributed springs 23 fixedly installed at one end of each clamping plate 22, with one end of each spring 23 fixedly connected to the fixed plate 19.

[0020] A rotating shaft 24 is rotatably mounted on the inner side of the support frame 12, and a fan 25 is fixedly connected to the outer side of the rotating shaft 24. A sector gear 26 is fixedly connected to one end of the fan 25, and a forward and reverse motor 27 is fixedly mounted on one end of the support frame 12. A full gear 28 is fixedly connected to the drive end of the forward and reverse motor 27, and the full gear 28 meshes with the sector gear 26.

[0021] By adopting the above technical solution, the fan 25 is started to dissipate heat from the workpiece during welding. In addition, the forward and reverse motor 27 controls the reciprocating rotation of the full gear 28, which drives the sector gear 26 to reciprocate. This causes the rotating shaft 24 to drive the fan 25 to reciprocate, expanding the heat dissipation area and effectively dissipating heat evenly from the workpiece. This prevents the workpiece from deforming due to excessive temperature during welding, thereby improving the yield rate.

[0022] A symmetrically distributed synchronous motor 29 is fixedly installed at one end of the support plate 14. The drive end of the synchronous motor 29 is fixedly connected to the corresponding lead screw 16. A synchronous chip 30 is fixedly installed at one end of each synchronous motor 29.

[0023] By adopting the above technical solution, the rotation of the lead screw 16 is controlled by setting a synchronous motor 29, and the operation of the two synchronous motors 29 is synchronously controlled by the synchronous chip 30.

[0024] Guide plates 31 are fixedly installed on the inner side of the strip groove 15, and one end of the moving block 17 is slidably sleeved on the outer side of the guide plate 31.

[0025] By adopting the above technical solution, guide plate 31 is set to help guide the moving block 17.

[0026] The bottom surface of the workbench 1 is fixedly equipped with an array of pads 32.

[0027] By adopting the above technical solution, the support effect of the workbench 1 is improved by setting the pad 32.

[0028] The workbench 1 is fixedly equipped with symmetrically distributed handles 33 on its side.

[0029] By adopting the above technical solution, the workbench 1 can be easily moved by using the handle 33.

[0030] An integrated controller 34 is fixedly installed on one side of the top of the V-shaped base 11.

[0031] By adopting the above technical solution, the operation of the laser welding machine 13 and the synchronous motor 29 can be easily controlled by setting up an integrated controller 34.

[0032] Working principle: First, the workpiece is placed on the support plate 14. Then, the synchronous motor 29 is started to control the lead screw 16 to rotate. The rotation of the lead screw 16 drives the moving block 17 to move. The moving block 17 then drives the fixed block 18 and the fixed plate 19 to move. The fixed plate 19 pushes the clamping plate 22 to move. The clamping plate 22, together with the V-angle of the V-shaped seat 11, clamps and positions the workpiece. The clamping piece 21 rotates on the cylinder block 20, and the effect of the spring 23 enhances the holding force. The triangular positioning formed by the clamping plate 22 and the V-shaped seat 11 facilitates the positioning and processing of workpieces of different shapes, improving versatility and convenience. The fan 25 is started to dissipate heat from the workpiece during welding. The forward and reverse motors 27 control the reciprocating rotation of the full gear 28. The full gear 28 drives the sector gear 26 to reciprocate, thereby causing the rotating shaft 24 to drive the fan 25 to reciprocate, expanding the heat dissipation area and effectively dissipating heat evenly from the workpiece. This prevents deformation caused by excessive temperature during welding, thereby improving the yield rate.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
