DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example

[0025] As attached Figure 1 To Attachment Figure 5 As shown:

[0026] A laser cladding welding machine includes a frame 1, a bracket 2 and a workbench 6. The bracket 2 is fixedly connected to the top of the frame 1, the bracket 2 is installed and limited by the frame 1, and the workbench 6 is installed above the middle of the frame 1. The workpiece is limited by being installed above the workbench 6 and is welded.

[0027] It should be understood that the above-mentioned fixed connection means that there can be no relative movement between the two. There are many ways of fixed connection. Here, bolts can be used for fixing, so that it is more convenient to disassemble and maintain the rack 1 later.

[0028] A slide rail is installed on the top of the bracket 2, and a slide 201 is slidably connected on the top of the slide rail. A motor corresponding to the slide 201 is installed inside the slide rail. When the slide 201 is driven to slide on the top of the slide rail by the motor as a driving member, the output end of the motor side is fixedly connected to a roller located in the slide rail. The motor is fixedly installed inside the slide 201. When the motor drives the roller to rotate, the roller will move inside the corresponding slide rail, so that it pushes the slide 201 to drive the crossbeam 3 fixedly connected above to move longitudinally. During the longitudinal movement of the crossbeam 3, the crossbeam 3 will drive the longitudinal beam 4 installed on the side to move. During the movement of the longitudinal beam 4, the welding head 402 installed on the side of the side bracket 401 will be driven to move together, thereby making the welding head 40 2 can move longitudinally to perform welding processing on the workpiece. During the movement of the longitudinal beam 4, an installation cavity 301 is provided inside the cross beam 3 and the longitudinal beam 4, and a motor is fixedly installed on the outer side of the installation cavity 301. One end of the threaded rod 302 rotatably connected inside the installation cavity 301 is fixedly connected to the side output end of the motor, so that during the operation of the motor, the side output end of the motor will drive the threaded rod 302 to rotate in the installation cavity 301, and during the rotation of the threaded rod 302, the threaded rod 302 will push the sliding sleeve 303 threadedly connected to the rod body to move in the installation cavity 301. An opening is provided on the side wall of the installation cavity 301, and the sliding sleeve 303 is fixedly connected to a clamping plate penetrating into the opening on the side wall, so that the threaded rod 302 pushes the sliding sleeve 303 to move When the screw rod 302 is in the working state, the sliding sleeve 303 is in the working state, and the sliding sleeve 303 is in the working state. ... The welding head 402 can be moved so that the welding head 402 can process the workpiece in a more comprehensive direction and angle during the welding process of the workpiece. A bogie 403 is installed on the side of the bracket 401, and the welding head 402 is fixedly installed on the top through the bogie 403, so that the bogie 403 can slide in the slide groove 405 provided on the side of the bracket 401 through the rotating block 404 fixedly connected at the back, so that the bogie 403 can drive the side welding head 402 to rotate, so that the welding head 402 can adjust the angle longitudinally, transversely and up and down. The welding head 402 can also be adjusted in an offset manner, so that the welding head 402 can be more flexible in the process of welding the workpiece, thereby improving the processing efficiency of the workpiece. After the rotating block 404 slides in the slide groove 405,The limiting rod 406 threadedly connected to the side wall of the bracket 401 can be rotated in so that the side end of the limiting rod 406 will abut against the side wall of the rotating block 404 inside the slide groove 405, thereby limiting the rotating block 404 in the slide groove 405 to prevent the bogie 403 from loosening after adjusting the angle.

[0029] A turntable 5 located at the bottom of the workbench 6 is fixedly installed above the middle part of the frame 1, and the workbench 6 is installed and limited at the top through the turntable 5. After the workpiece is installed above the workbench 6, when the workbench 6 is pushed to rotate above the turntable 5, the slider 601 fixedly connected to the bottom of the workbench 6 will slide in the sliding cavity 501 opened above the turntable 5. After the workbench 6 is rotated above the turntable 5, the locking screw 602 threadedly connected on the side wall of the turntable 5 is rotated, so that the locking block fixedly connected to the side end of the locking screw 602 is squeezed on the side wall of the slider 601, and then the slider 601 is limited in the sliding cavity 501 to prevent the workbench 6 from loosening above the turntable 5, so that the workpiece installed above the workbench 6 can be rotated to adjust the processing angle, so that the workpiece can be more accurate during the processing, thereby improving the processing efficiency of the workpiece.

[0030] Working principle: When the slide 201 is driven by the motor as a driving member to slide on the top of the slide rail, the motor will drive the roller to move inside the corresponding slide rail, thereby pushing the slide 201 to drive the upper crossbeam 3 to move longitudinally. During the longitudinal movement of the crossbeam 3, the crossbeam 3 will drive the longitudinal beam 4 installed on the side to move. During the movement of the longitudinal beam 4, the welding head 402 installed on the top of the side bracket 401 will be driven to move together, so that the welding head 402 can move longitudinally to perform welding processing on the workpiece. During the movement of the longitudinal beam 4, the motors on the sides of the crossbeam 3 and the longitudinal beam 4 are driven to operate. When the motor is running, it will drive the threaded rod 302 through the side output end. When the slide 303 is moved in the installation cavity 301, the clamping plate on the side of the slide 303 will slide in the opening and limit it, so that the slide 303 will not rotate with the threaded rod 302. When the slide 201 drives the welding head 402 on the side of the cross beam 3 to move longitudinally, the threaded rod 302 inside the cross beam 3 rotates, and the threaded rod 302 pushes the slide 303 to move, which will drive the welding head 402 on the side of the longitudinal beam 4 to move horizontally. The bogie 403 can also slide in the slide groove 405 on the side of the bracket 401 through the rotating block 404 on the back, so that the bogie 403 can drive the side welding head 402 to rotate, so that the welding head 402 can also be adjusted in an offset manner, so that the welding head 402 can be more flexible in the process of welding the workpiece. After the rotating block 404 slides in the slide groove 405, the limiting rod 406 on the side wall of the bracket 401 can be turned in, so that the side end of the limiting rod 406 will be against the side wall of the rotating block 404 inside the slide groove 405, thereby rotating the rotating block 404. After the workpiece is limited in the slide groove 405 and installed above the workbench 6, when the workbench 6 is pushed to rotate above the turntable 5, the slider 601 at the bottom of the workbench 6 will slide in the slide cavity 501 inside the turntable 5, so that the workbench 6 will rotate above the turntable 5. After the workbench 6 is rotated to adjust the processing angle of the workpiece, the locking screw 602 on the side wall of the turntable 5 is rotated so that the locking block at the side end of the locking screw 602 is squeezed on the side wall of the slider 601, and then the slider 601 is limited in the slide cavity 501 to prevent the workbench 6 from loosening above the turntable 5, so that the workpiece is more accurate during the processing and the processing efficiency of the workpiece is improved.
