By setting the locking device 6 and the first spring block 8 and the second spring block 9, the connecting block 603 is locked by using the first spring block 8 and the second spring block 9, which can effectively assist the clamping device 7 to be fixed on the top of the support platform 1, thereby preventing the roller from moving during the rotation process. The overall safety of the user can be effectively guaranteed to prevent the roller from being injured due to negligence during the installation process.

[0033] The two first sprocket groups 2 each have three sprockets. The first sprocket group 2 and the chain 3 cooperate with each other through a sprocket structure. A gear 10 is fixedly connected to the rotating rod 5, and one side of the gear 10 is cooperated with a first motor 11. By setting the first sprocket group 2 and the chain 3, through the cooperation of the sprockets, the user can stably transport the roller installed between the two clamping devices 7 to the top of the support table 1.

[0034] The locking assembly includes a first spring block 8 and a second spring block 9. Second grooves 12 are provided on the tops of both sides of the support platform 1. Third grooves 13 are provided on the tops of both sides of the support platform 1. The first spring block 8 is fixedly connected in the two second grooves 12. The second spring block 9 is fixedly connected in the two third grooves 13. The tops of the first spring block 8 and the second spring block 9 are movably connected in the second slide groove 606 on the connecting block 603.

[0035] The two clamping devices 7 are fixedly connected to the second motor 16 on one side close to the connecting block 603, the collecting box 14 is movably connected to the center position of the top of the support platform 1, and the laser welding fixture 15 is slidably connected to one side of the top of the support platform 1.

[0036] There are inclined surfaces on both sides of the top of the first spring block 8, and the two inclined surfaces are staggered on the top of the first spring block 8. There are inclined surfaces on both sides of the bottom of one end of the sliding block 604, and the bottom of one side of the sliding block 604 is in contact with one side of the top of the first spring block 8. There are inclined surfaces on both sides of the top of the second spring block 9, and the shape of the sliding block 604 is L-shaped.

[0037] The power assembly includes a gear 10 and a first motor 11 . The gear 10 is fixedly connected to the rotating rod 5 , and one side of the gear 10 is cooperatively connected to the first motor 11 .

[0038] The tops of the first spring block 8 and the second spring block 9 are movably connected in the second slide groove 606, one end of the clamping block 6031 is movably connected between the first spring block 8 and the second spring block 9, one side of the clamping block 6031 contacts the non-slanted surface of the first spring block 8, and the other side of the clamping block 6031 contacts the non-slanted surface of the chamfered bottom of the second spring block 9, thereby achieving the effect of fixing and locking the clamping block 6031 on the non-slanted surface between the first spring block 8 and the second spring block 9.

[0039] The working process is as follows:

[0040] S1. The user installs the roller between the two clamping devices 7, and then starts the first motor 11. The first motor 11 drives the rotating rod 5 and the gear 10 to rotate. The rotation of the rotating rod 5 drives the second sprockets 4 at both ends to rotate. The rotation of the second sprocket 4 drives the chain 3 to roll on the first sprocket set 2. At this time, the chain 3 drives the fixing block 601 and the connecting block 603 back to the top of the support platform 1 (such as Figure 2 and Figure 1 shown);

[0041] S2. When the fixed block 601 and the connecting block 603 return to the top of the support platform 1, the inclined surface on one side of the bottom of the connecting block 603 pushes the first spring block 8 to make it shrink into the second groove 12 as a whole, and the connecting block 603 continues to move forward, thereby pushing the second spring block 9 to shrink into the third groove 13 through the inclined surface on one side of the connecting block 603, and the chain 3 drives the fixed block 601 and the connecting block 603 to continue to move forward. At this time, the sliding block 604 is not stuck between the first spring block 8 and the second spring block 9, and the fixed block 601 moves forward through the first groove 602 to push the second protrusion 608 on the sliding block 604 to move, so that one end of the sliding block 604 is stuck between the first spring block 8 and the second spring block 9, and the clamping block 6031 set on one side of the second slide groove 606 opened on the connecting block 603 will also be stuck between the first spring block 8 and the second spring block 9, which plays an auxiliary locking role as a whole (such as Figures 6 to 10 shown);

[0042] S3, stop the first motor 11, lock the fixing block 601, then move the laser welding fixture 15 to a suitable position, start the second motor 16, so that the second motor 16 drives the roller on the clamping device 7 to rotate, start the laser welding fixture 15 to process the surface of the roller, and collect the metal debris through the collection box 14;

[0043] S4, after the surface treatment of the roller is completed, the second motor 16 is turned off, the first motor 11 is reversed, the chain 3 moves to drive the fixed block 601 to move, and the fixed block 601 will drive the second protrusion 608 and the sliding block 604 in the first groove 602 to move. Since the bottom end of the sliding block 604 is provided with an inclined surface, it will push the first elastic block 8 to retract into the second groove 12 (such as Figure 8 shown);

[0044] S5. When the first protrusion 607 fixedly connected to the fixing block 601 slides to the other side in the first slide groove 605 provided on the connecting block 603, the first elastic block 8 is in a retracted state, and the bottom of the connecting block 603 pushes the second elastic block 9 to retract into the third groove 13. The clamping block 6031 provided on one side of the second slide groove 606 provided on the connecting block 603 moves forward (as shown in FIG. 1 ) without the obstruction of the first elastic block 8. Figure 7 and Figure 8 As shown), the fixed block 601 continues to drive the connecting block 603 to move, so that the connecting block 603 leaves the movable support table 1, and then the chain 3 transports the fixed block 601 and the connecting block 603 to the bottom of one side of the equipment, and finally removes the roller between the two clamping devices 7.

[0045] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
