Description

Technical Field

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

[0002] Fusion welding refers to the welding process in which the weld joint is brought to a molten state under the action of high temperature and other factors. Since the workpieces being welded are closely attached together, under the influence of temperature field, gravity, etc., without pressure, the molten liquid of the two workpieces will mix. After the temperature drops, the molten part solidifies, and the two workpieces are firmly welded together, thus completing the welding method. Fusion welding includes many types, such as electric arc welding (electric welding), gas welding, laser welding, electron beam welding, etc.

[0003] Laser welding machines are a type of fusion welding machine. During workpiece processing, to meet user needs and connect multiple different workpieces together, a fusion welding machine is required. When using a fusion welding machine, a positioning component is needed to position the workpieces, facilitating welding. A search reveals Chinese patent CN216178629U, which discloses a workpiece clamping and positioning component. Its key technical features include: a fixed base, a fixed plate welded to one end of the upper surface of the fixed base, a servo motor fixedly mounted on one side of the fixed plate, and a lead screw connected to the output end of the servo motor. A support plate is welded to the other end of the upper surface of the fixed base. The two ends of the lead screw are rotatably connected to the fixed plate and the lead screw, respectively. A slider is threaded onto the circumference of the lead screw. A worktable is welded to the upper surface of the slider. A side plate is welded to the upper surface of the worktable. A servo electric cylinder is fixedly installed on the surface of the side plate. A moving plate is fixedly connected to the output end of the servo electric cylinder. Two sets of clamping mechanisms are symmetrically arranged on the outer surface of the moving plate. The servo electric cylinder drives the moving plate to move, and the moving plate drives the clamping mechanism to move, so that the clamping mechanism clamps the edge of the workpiece, thereby facilitating the fixation of the workpiece and making it easier to process.

[0004] The existing technical solutions mentioned above have the following drawbacks: during the use of this positioning component, it is impossible to clean the welding slag generated during welding. The welding slag adheres to the surface of the positioning component, which can easily lead to unevenness of the surface of the positioning component and affect the placement of workpieces by the positioning component.

The welding machine 2 is a common laser welding machine on the market.

[0025] Cleaning component 8 is located on the back of clamping block 7;

[0026] The collecting mechanism 9 has its input end connected to the right side of the frame 3, and its left side is fixedly connected to the right side of the workbench 1.

A scraper 803 is fixedly connected to the surface of the crossbar 802. The scraper 803 is located inside the clamping block 7, and the bottom of the scraper 803 contacts the top of the placement plate 4.

[0028] As a technical optimization of this utility model, the top of the placement plate 4 can be cleaned by setting the cleaning component 8, so as to prevent the molten metal and welding slag splashed by the welding machine 2 from adhering to the top of the placement plate 4 when welding the workpiece.

[0029] refer to Figure 3 The collection mechanism 9 includes a connecting pipe 901, the input end of which is connected to the right side of the frame 3, the bottom of which is connected to a box 902, the bottom of which is connected to a fan 903, the left side of which is fixedly connected to the right side of the workbench 1, and a dust bag 904 is provided inside the box 902.

[0030] As a technical optimization of this utility model, the collection mechanism 9 can collect the molten metal and welding slag cleaned by the cleaning component 8, preventing the molten metal and welding slag from accumulating on the top of the placement plate 4 and affecting the placement of workpieces on the placement plate 4.

[0031] refer to Figure 3 A fixing frame 10 is provided at the top inside the box 902. The inner wall of the fixing frame 10 is fixedly connected to the top of the surface of the dust bag 904. A cover plate 11 is fixedly connected to the right side of the fixing frame 10. The left side of the cover plate 11 is fixedly connected to the right side of the box 902.

[0032] As a technical optimization of this utility model, the position of the dust bag 904 can be fixed and limited by the setting of the fixing frame 10, which facilitates the collection of molten metal and welding slag. The sealing of the box 902 can be increased by the setting of the cover plate 11, which facilitates the fan 903 to extract the molten metal and welding slag from the bottom of the frame 3.

[0033] refer to Figure 3 Both sides of the box 902 are provided with movable grooves that cooperate with the fixing frame 10. The top of the placement plate 4 is provided with a through hole.

The front of the limiting block 14 is fixedly connected to the back of the clamping block 7. A limiting groove that works with the limiting block 14 is opened on the back of the frame 3.

[0036] As a technical optimization of this utility model, the position of the clamping block 7 can be limited and supported by the cooperation of the limiting block 14 and the limiting groove, while preventing the clamping block 7 from falling off the frame 3.

A bushing 16 is fitted on the front side of the surface of the crossbar 802. The front of the bushing 16 is fixedly connected to the back of the threaded sleeve 6.

[0038] As a technical optimization of this utility model, the protective shell 15 can protect and limit the motor 801, and the bushing 16 can limit the position of the crossbar 802 and the scraper 803, preventing the crossbar 802 and the scraper 803 from shaking during rotation.

[0039] The working principle and usage process of this utility model are as follows: In use, the user places the workpiece on top of the placement plate 4, then rotates the handwheel 13 clockwise. The rotation of the handwheel 13 drives the forward and reverse threaded rods 5 to rotate, which in turn moves the threaded sleeve 6, clamping block 7, and limiting block 14 inwards, causing the clamping block 7 to clamp and position the workpiece on top of the placement plate 4. Afterwards, the user starts the welding machine 2 to weld the workpiece. After welding is completed, the operation is reversed to release the clamping block 7 from the workpiece. At this point, the user rotates the handwheel 13 clockwise. Move the screw sleeve 6 and clamping block 7, and start the motor 801. The output end of the motor 801 drives the crossbar 802 and scraper 803 to rotate counterclockwise, so that the rotating scraper 803 cleans the welding slag attached to the top of the placement plate 4. The welding slag generated by cleaning enters the bottom of the frame 3 through the through hole. Then the user starts the fan 903. The input end of the fan 903 sucks up the welding slag inside the frame 3 through the box 902 and the connecting pipe 901, so that the welding slag enters the dust bag 904 in the box 902, and the welding slag can be collected at this time.

[0040] In summary, the workpiece positioning component of this welding machine cleans the welding slag on the top of the placement plate 4 through the cleaning component 8, and then the collection mechanism 9 collects the cleaned welding slag to prevent it from scattering everywhere. This solves the problem that the positioning component cannot clean the welding slag generated during welding, and the welding slag adheres to the surface of the positioning component, which can easily lead to unevenness of the surface of the positioning component and affect the placement of workpieces by the positioning component.
