The invention relates to welding equipment for a rotary target, which comprises the following working procedures:
in the invention, in the initial state, the electromagnet 73 is in a power-off state, the pawl spring 72 is in a release state, the pawl 75 is abutted with the outer circular surface of the annular ratchet 70, and the reset torsion spring 71 is in a release state.
Two sections of rotary targets to be welded are respectively arranged between the left clamping seat 30 and the right clamping seat 30 and the workbench 20 at the left side and the right side.
The lifting motor 40 is started to drive the lifting motor shaft 49 to rotate, so that the driving belt pulley 41 rotates, the driving belt 42 drives the driven belt pulley 43 to rotate, so that the lifting screw rod 44 moves downwards, the driven adjusting wheel 64 moves downwards, the clamping force adjusting seat 60 moves downwards, the clamping seat 30 moves downwards through the pressure spring 33, the upper clamping wheel bracket 32 moves downwards, and the upper clamping wheel 31 moves downwards.
When the upper clamping wheel 31 touches the surface of the target, the upper clamping seat 30 stops moving downwards due to the reaction force of the target to the upper clamping wheel 31, and the lifting screw rod 44 continues to move downwards due to the rotation of the lifting motor 40, at this time, the lifting screw rod 44 drives the limiting block 45 to move downwards continuously, so that the limiting block 45 is far away from the lower end face of the clamping seat 30, and the contact switch 46 moves downwards to be separated from the lower end face of the clamping seat 30, so that the contact switch 46 is triggered.
The contact switch 46 is triggered, so that the lifting motor 40 is turned off, and the lifting screw 44 stops moving downwards, and the upper clamping wheel 31 applies pressure to the target surface, namely the compression amount of the pressure spring 33.
During the rotation of the elevator motor shaft 49, the elevator motor shaft 49 drives the reset torsion spring 71 to twist the power.
During the lowering of the holder 30, the welding box 50 moves downward together with the holder 30, and when the upper holder 30 stops moving downward, the welding box 50 also stops moving downward, and the lower end of the welding gun 52 approaches the target surface.
After the lifting motor 40 is turned off, the pawl 75 abuts against the outer circumferential surface of the annular ratchet wheel 70, so that the annular ratchet wheel 70 cannot rotate reversely under the torsion action of the reset torsion spring 71, and the reset torsion spring 71 is kept in a power storage state.
At this time, the welding gun 52 is moved left and right so that the welding gun 52 stops after being aligned with the weld.
At this time, the rotating motor 21 is started, so that the rotating motor 21 drives the friction wheel shaft 23 to rotate, thereby enabling the friction wheel 22 to rotate, further enabling the lower clamping wheel 31 to rotate, and further driving the target to rotate.
Simultaneously, the welding gun 52 is started to weld the left and right targets, and after the welding is completed, the rotating motor 21 and the welding gun 52 are turned off.
At this time, the electromagnet 73 is started, so that the electromagnet 73 electrically attracts the pawl 75, the pawl 75 moves backwards into the pawl sliding cavity 74 against the elastic force of the pawl spring 72, and the elevator motor shaft 49 reverses under the torsion action of the reset torsion spring 71, so that the driving pulley 41 is driven to reverse, the elevator screw 44 moves upwards, and the upper clamping force adjusting seat 60 moves upwards to the initial position.
When the clamping force adjusting seat 60 drives the clamping seat 30 to move upwards to the initial position, the electromagnet 73 is turned off, and the device is restored to the initial state.
If the clamping force of the clamping wheel mechanism is required to be adjusted according to the wall thickness of the rotary target to be welded, the clamping force indicating disc 62 is rotated, so that the driving adjusting wheel 61 rotates, the driven adjusting wheel 64 is driven to rotate by the belt 63, the driven adjusting wheel 64 moves up and down along the lifting screw 44, the distance between the clamping force adjusting seat 60 and the clamping seat 30 is changed, namely, the compression amount of the pressure spring 33 is changed, and the clamping force when the upper clamping wheel 31 clamps the target is changed.
It will be apparent to those skilled in the art that various modifications to the above embodiments may be made without departing from the general spirit and concepts of the invention. Which fall within the scope of the present invention. The protection scheme of the invention is subject to the appended claims.
