Lower section.
It is of the present utility model to have technical effect that：This utility model product structure is simple, easy to process, assembles and maintenance side
Just；Melting welding state can be indicated, security performance is improved；Rapid, safety is separated, and separating force is adjustable；Protection device can reset tune
Perfect square just, can be reused, and save material.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is further described.
In Fig. 1, including slide block 1, ratchet 2, ratchet 3, clamp 4, actuating arm 5, back-moving spring 6, indication piece 7, microswitch 8
Deng.
As shown in figure 1, this utility model is a kind of chopper melting welding protection mechanism, the actuating arm 5 for arranging is rotated including one,
5 upper one end of the actuating arm is connected with indication piece 7, the linkage microswitch 8 of indication piece 7, the 5 top other end of the actuating arm
Connection back-moving spring 6；5 lower end of actuating arm extends to 4 surface of clamp, and 3 one end of ratchet is rotationally connected with clamp 4, and with driving
5 lower end of arm is connected, and rotates and arrange ratchet 2 beside clamp 4, and ratchet 3 blocks ratchet 2, arranges slide block 1 below ratchet 2.
The rotating shaft of actuating arm 5 is placed in 4 top position of clamp, and 5 lower end of actuating arm is provided with arc groove, 3 end of ratchet and institute
State arc groove to be engaged.The rotation connection end of generally ratchet 3 is also connected with one piece of guide pad, and guide pad is placed in the circular arc of actuating arm
In groove, when ratchet 3 is rotated, 5 synchronous axial system of actuating arm, after actuating arm 5 pushes microswitch 8, is realized resetting by back-moving spring 6
Action.
Indication piece 7 is obliquely installed, and microswitch 8 is placed in the obliquely downward of indication piece 7, and actuating arm 5 drives indication piece 7, by referring to
Show that part 7 promotes microswitch 8 to carry out corresponding actions.
The course of work of the present utility model is as follows：If chopper melting welding, now electricity is grasped when sub-gate signal is obtained, slide block
1 moves to OFF（The direction of arrow）, now ratchet 3 bear the motion counter-force from ratchet 2（Counter-force size is handle power）；
When slide block 1 moves to the extreme position of melting welding, slide block 1 stops, and 3 counter-force of ratchet increases；When counter-force increases to a numerical value
（More than the torque that back-moving spring 6 is provided）, ratchet 3 will be to Impact direction movement until ratchet 3 is disengaged.When ratchet 3 is moved, promote
Actuating arm 5 is rotated, and actuating arm 5 promotes indication piece 7 to rotate, until indication piece 7 pushes down microswitch 8, disconnects motor circuit, this
When ratchet 3 thoroughly disengage with ratchet 2 after, move to the draw-in groove maximum position of clamp 4, now the no longer stress of ratchet 3, actuating arm
5 are subject to the power of spring 6 back to move, and band pawl 3 is to draw-in groove upper direction, it is ensured that ratchet 3 is no longer contacted with ratchet 2, indicates
By buckle, part 7 ensures which no longer turns round, it is ensured that mechanism will not be powered again.Now mechanism provides power, slide block meeting without motor
ON positions are moved in the presence of circuit breaker handle counter-force.
Operation principle：When chopper melting welding, now by the power under ON to OFF state much larger than separating brake under normal condition
Power, in the extreme position of melting welding, thrust of the ratchet effect on ratchet is supplied to the power of ratchet 2 much larger than actuating arm 5 so as to
Move out, promote actuating arm 5 to move, actuating arm 5 drives indication piece 7, by microswitch, makes mechanism's power-off, reaches protection
Purpose.
