Workpiece welding is a process of connecting two or more metal materials together through hot processing; common workpiece welding methods include arc welding, gas welding, laser welding, etc. In order to improve the welding accuracy of workpieces, it is necessary to position the workpiece fittings to be welded.

[0003] The currently used welding positioning mechanisms still have the following problems:

[0004] 1. The workpiece to be welded and processed needs to be placed after the workpiece after welding and processing is removed, which increases the installation time of the workpiece and reduces the welding efficiency of the workpiece;

[0005] 2. The workpiece after welding and processing generally needs to be manually removed by workers, resulting in the workpiece after welding being prone to scalding workers and posing a safety hazard;

[0006] 3. The workpiece is generally positioned pneumatically or electrically, and it is impossible to automatically position the workpiece fittings to be welded before welding and processing. As a result, it is necessary to press the control button to position the workpiece before welding, and it is necessary to press the control button to release the positioning after the workpiece is welded, which increases the operation steps and is not conducive to the efficient welding of the workpiece.

[0025] 2. In the present invention, it is convenient for the operator to connect the laser welding head and the welding slider through screws; when the motor works, the driving lead screw can drive the welding slider to move, realizing the automatic welding of the workpiece;

[0026] In addition, it plays an automatic clamping role for the workpiece to be welded, saving the clamping time of the workpiece to be welded and improving the welding efficiency of the workpiece; when the two clamping and extrusion frames are separated from the two rectangular movable rods, the two V-shaped clamping plates automatically move outward under the action of two reset springs A, facilitating the sliding of the welded workpiece and also facilitating the operator to pre-install the workpiece to be welded;

[0027] In addition, when welding the workpiece on the left side, the operator can pre-install the workpiece to be welded on the right working station, and when welding the workpiece on the right side, the operator can pre-install the workpiece to be welded on the left working station, saving the installation time of the workpiece to be welded and improving the welding efficiency of the workpiece; the setting of the two support and limit rods plays a limiting role on the connecting discharge plate, ensuring that when the workpiece is welded, the connecting discharge plate is in a stable state, preventing the workpiece from moving during welding and ensuring the welding accuracy of the workpiece.

[0061] Specific usage method and function of this embodiment:

[0062] When the present invention is in use, first, the staff installs the mounting base plate 100 in the welding workshop through bolts, and then places the workpiece fittings to be welded between the two V-shaped clamping plates 303. After that, the motor 503 is started. When the motor 503 works, the driving lead screw 504 can drive the welding slider 502 to move, realizing the automatic welding of the workpiece; the setting of the two clamping and squeezing frames 603 plays an automatic clamping role for the workpiece to be welded, saving the clamping time of the workpiece to be welded and improving the welding efficiency of the workpiece; when the two clamping and squeezing frames 603 are separated from the two rectangular movable rods 302, the two V-shaped clamping plates 303 automatically move outward under the action of the two return springs A 305, facilitating the sliding of the welded workpiece and also facilitating the staff to pre-install the workpiece to be welded in advance; when welding the workpiece on the left side, the staff can pre-install the workpiece to be welded on the right working station, and when welding the workpiece on the right side, the staff can pre-install the workpiece to be welded on the left working station, saving the installation time of the workpiece to be welded and improving the welding efficiency of the workpiece; the setting of the two support and limit rods 604 plays a limiting role for the connecting and discharging plate 203, ensuring that the connecting and discharging plate 203 is in a stable state during workpiece welding, avoiding the movement of the workpiece during welding, and ensuring the welding precision of the workpiece;

[0063] After welding, the worker starts the electric cylinder 401 to contract the output shaft of the electric cylinder 401. At this time, the output shaft of the electric cylinder 401 drives the temporary storage box body 404 to move, so that the temporary storage box body 404 moves out of the protection frame 403. When the output shaft of the electric cylinder 401 contracts, it can push the unloading plate 402 to squeeze the U-shaped unloading rack 204. After the U-shaped unloading rack 204 receives the extrusion force, it can turn downward, causing the connecting unloading plate 203 to tilt, and the welded workpiece can automatically slide into the temporary storage box body 404. When the welded workpiece is unloaded, when the worker extends the output shaft of the electric cylinder 401, the output shaft of the electric cylinder 401 drives the temporary storage box body 404 to move, so that the temporary storage box body 404 moves into the protection frame 403, preventing the worker from being scalded by the welded workpiece when installing the workpiece to be welded. When the worker extends the output shaft of the electric cylinder 401, the connecting unloading plate 203 can automatically reset under the action of the two reset bending springs 207. When the workpiece in the temporary storage box body 404 needs to be transferred, the worker pulls out the two handles on the temporary storage box body 404 outward. At this time, the output shaft of the electric cylinder 401 can squeeze the two circular connecting rods 406 to move outward, separating the two circular connecting rods 406 from the arc-shaped groove 4011, facilitating the transfer of the welded workpiece. When the temporary storage box body 404 needs to be reset, the worker first slidably installs the temporary storage box body 404 inside the protection frame 403, and then pushes the two handles on the temporary storage box body 404, so that the two circular connecting rods 406 are inserted into the arc-shaped groove 4011.
