Position is welded and fixed, and to be formed to 1 lower end position of main body along the closure of 1 length direction of main body, is used to support drive rod 5.Together
When, in the present embodiment, two side positions held on the body 1 are respectively provided with a lifting lug 3, are realized and loop wheel machine for connecting lifting rope
Connection.
In conjunction with shown in Fig. 1, when carrying out turning operation to drive rod using the stock overturning tooling of the utility model, protect first
Drive rod 5 is moved to the inside of main body 1 by water holding placing flat state, and the bottom of drive rod 5 is made to be contacted with support plate 2；It connects
The open side that baffle 4 is placed in main body 1, to which drive rod 5 to be fixed on inside main body 1；Then by lifting rope by lifting lug 3 with
Loop wheel machine connects, you can carries out drive rod 5 by being horizontally arranged the overturning placed vertically.In the process, the open side of main body 1
Always upward, to keep to the holding state of drive rod 5, in this way by main body 1 to the support of 5 main body section of drive rod and
Support of the support plate 2 to 5 bottom of drive rod, can to avoid the flexural deformation that drive rod 5 may occur in switching process and
Degree of disturbing deform, to ensure that overturning after drive rod 5 verticality and straightness, and then ensure that subsequently lift it is smooth into
The normal operation in row and later stage.
Further, since drive rod 5 is stainless steel, therefore when drive rod 5 is fixed, as the case may be may be used
To set stainless steel thin slice in drive rod 5 and the contact position pad of overturning tooling, drive rod 5 is avoided directly to be connect with other metal materials
It touches and pollution condition occurs, such as avoid directly being in contact with using the main body 1 of carbon steel, to improve the guarantor to drive rod 5
Shield.
In conjunction with shown in Fig. 1 and Fig. 2, the stock of the utility model overturns tooling, further includes operating lever 6, and in main body 1
One side is equipped with guide sleeve 7, another side is equipped with cutting ferrule 8.Wherein, operating lever 6 is threaded through in guide sleeve 7, and is being led
It can be moved back and forth along the length direction of main body 1 under to the guiding role of set 7, one end and 6 company of being welded and fixed of operating lever of baffle 4
It connects, the other end is between main body 1 and cutting ferrule 8.In the present embodiment, cutting ferrule 8 is L-shaped structure, and one end and the welding of main body 1 are solid
Fixed, the other end and the length direction of main body 1 are arranged in parallel, and keep a determining deviation with main body 1, in order to place baffle 4.
It is further preferred that the length direction along main body 1 is equipped with multiple baffles 4 and cutting ferrule 8, and baffle 4 and cutting ferrule 8 one
One corresponds to.All baffles 4 are welded and fixed with operating lever 6 simultaneously, and in all baffles 4 are generally aligned in the same plane.At this point, by right
The lifting of operating lever 6 operates, you can all baffles 4 is driven to be carried out at the same time upper and lower reciprocating movement.In this way, leading in guide sleeve 7
To under effect, baffle 4 can be driven to move by the manual pull joystick of length direction along main body 16, to put baffle 4
Enter in cutting ferrule 8 or taken out from cutting ferrule 8, realizes the fixation to drive rod 5 and release and fix.
In the present embodiment, operating lever 6 is designed as L-shaped structure, including perpendicular end and horizontal end.Wherein, perpendicular end, which is threaded through, leads
Into set 7, horizontal end is located at the top position of a guide sleeve 7 topmost, that is, is located at a guide sleeve 7 nearest apart from lifting lug 3
Top position.In this way, the maximum distance that operating lever 6 is moved down along guide sleeve 7 can be limited by the horizontal end of operating lever 6,
It is slid to avoid occurring the unexpected of operating lever 6, ensures the safety and stability of the course of work.
In addition, a limit hole is additionally provided in operating lever 6, for inserting spacer pin 9.Limit hole is located at guide sleeve 7
Lower position, and the distance between limit hole and guide sleeve 7 are less than between the lower edge and the top edge of cutting ferrule 8 of baffle 4
Distance.In this way, only by spacer pin 9 after being taken out in limit hole, baffle 4 could be taken from cutting ferrule 8 by pull joystick 6
Go out, so as to prevent in switching process, operating lever 6 is surprisingly slided along the length direction of main body 1 and by baffle 4 from cutting ferrule 8
In take out of, to avoid release unexpected to drive rod 5 of baffle 4 from fixing, and then ensure that baffle 4 is to drive rod 5 in switching process
Fixed stability and reliability.
Further, one end of spacer pin 9 is connect by steel wire rope 10 with guide sleeve 7, so as to avoid losing for spacer pin 9
It loses, ensures the convenience used spacer pin 9.
