The course of work of the present invention：
Remove cutting edge process：Cold shears is cut into tire 10 reclined and cut after tire locating piece 12 places, promote positioning trolley to paste locating rack 7
The side of cutting edge 9 is against, two latches 4 are sequentially inserted into the through hole of the through hole of latch connecting plate 5 and chute 3, makes to cut the He of tire 10
Cutting edge 9 is positioned.Vertical shift dolly 20 is promoted to make the collet head 13 of the front end of pneumatic impact spanner 17 close to the spiral shell of the front end of cutting edge fixing bolt 8
It is female（That is cutting edge fixing nut）, promote cross traveling trolley 21 collet head 13 of pneumatic impact spanner 17 is directed at cutting edge fixing nut, now
The center line of collet head 13 should be overlapped with the center line of cutting edge fixing bolt 8, be otherwise accomplished by two vertical guide rods 30 of release and entered
Row adjustment.Vertical shift dolly 20 is promoted collet head 13 is entangled cutting edge fixing nut again, operation pneumatic impact spanner 17 removes nut,
After this nut is removed, vertical shift dolly 20 is promoted collet head 13 is left to cut and is promoted cross traveling trolley to be directed at collet head 13 again after tire 10
Next cutting edge fixing nut, is removed until all nuts are removed after finishing, extraction latch 4 pushes locating rack 7 open one by one successively, then
Cutting edge fixing bolt 8 is removed successively, cutting edge 9 is finally removed.
Cutting edge process is installed：Cold shears is cut into tire 10 reclined and cut after tire locating piece 12 places, cutting edge 9 is positioned over and cuts tire 10
On the concave station of side, after all cutting edge fixing bolts 8 are put on, positioning trolley is promoted locating rack 7 is posted by the side of cutting edge 9,
Two latches 4 are sequentially inserted into the through hole of the through hole of latch connecting plate 5 and chute 3, makes to cut tire 10 and cutting edge 9 is positioned.According to
Secondary screw-in cutting edge fixing nut, promotion vertical shift dolly 20 makes the collet head 13 of the front end of pneumatic impact spanner 17 close to cutting edge fixing nut,
Cross traveling trolley 21 is promoted the collet head 13 of pneumatic impact spanner 17 is directed at cutting edge fixing nut, now the center line of collet head 13 should be with
The center line of cutting edge fixing bolt 8 is overlapped, and is otherwise accomplished by two vertical guide rods 30 of release and is adjusted.Promote vertical shift small again
Car 20 makes collet head 13 entangle cutting edge fixing nut, and operation pneumatic impact spanner fastens nut, after the fastening of this nut, promotes vertical shift small
Car 20 makes collet head 13 leave to cut and promote cross traveling trolley collet head 13 is directed at next nut again after tire 10, fastens one by one successively straight
After being finished to the fastening of all nuts, extract latch 4 and push locating rack 7 open.
In actual application, because the collet head 13 on pneumatic impact spanner 17 can directly stretch to cutting edge fixing nut, institute
To be fixed on the thin shape device 11 cut on tire 10 by thin shape device fixing bolt the dress of cold shears lower scissor blade can be completed without removing
Match somebody with somebody.
In actual use, positioning trolley can not only play a part of positioning scissors tire, and tight in pneumatic impact spanner
Gu the effect for preventing that bolt from retreating is may also function as during cutting edge fixing bolt, so as to reduce the input of fixing bolt personnel；Work as horizontal stroke
When moving dolly transverse shifting, can accordingly it be stopped according to the position of cutting edge fixing bolt, to realize tearing open one by one for nut
Remove or fasten；When vertical shift dolly is vertically moved, pneumatic impact spanner is moved, and the collet head of pneumatic impact spanner will stretch to cutting edge and consolidate
Nut is determined, because pneumatic impact spanner collet head can directly be inserted in working position in good time, so both can guarantee that fastening or remove cutting edge
Torque required by fixing nut, can realize the assembling of lower scissor blade in the case where not removing corbel back slab and thin shape device again, so that
The input of assembly crewman is further reduced on the premise of guarantee assembling quality；When assembling different batches or different size are cut
During sword, because the centre-height of cutting edge fixing bolt is different, the lifting by being arranged on vertical shift dolly is at this moment accomplished by
Mechanism adjusts the height of pneumatic impact spanner, to meet the assembling needs of different batches or different size cutting edge.
After the frock comes into operation, the assembly work per pair cutting edge is by averagely needing 4 people to complete within 1.5 hours to be reduced to only
Need 1 people just can complete for 0.5 hour, cold shears cutting edge assembly work efficiency is increased dramatically, meet production
Need, also greatly reduce the labor intensity of worker.The device has practical, reliable operation, easy to operate, dimension simultaneously
Shield is simple, low cost and other advantages, is with a wide range of applications and promotion prospect.
