Hole.
The external diameter for being oriented to push rod is not more than the aperture of the stamping holes.
What the drive device included being vertically arranged is used to be set with the sleeve for being oriented to push rod, and the sleeve is fixed on mobile branch
On frame, the open top of the sleeve is stretched for being oriented to push rod, and the bottom opening of the sleeve is inserted for the piston rod of cylinder
Enter, the first tracheae connected with source of the gas is provided with below the side wall of the cylinder, is provided with above the side wall of the cylinder and connects with source of the gas
The second logical tracheae.
The open top inwall of the sleeve is provided with guide sleeve, and the internal diameter of the guide sleeve is outer with the guiding push rod
Footpath is identical；Formed with limiting section on the guiding push rod, the limiting section is in cylindrical structural, the diameter of section of the limiting section
More than the external diameter of the guiding push rod.
The beneficial effects of the utility model are：
1. the utility model is simple in construction, stamping holes and the centering rate of accuracy reached of bolt are enabled to absolutely；
2. the utility model can be oriented to the diameter and collapsing length of push rod by changing, promote the use of all
It is very with practical value on the bolt of model and other similar structures.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is along A-A profile in Fig. 1；
Fig. 3 is use state figure of the present utility model.
In figure, 1 bolt, 2 are oriented to push rod, 21 limiting sections, 3 stamping holes, 5 sleeves, 6 cylinders, 61 first tracheaes, 62 second gas
Pipe, 7 guide sleeves.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
Referring to Fig. 1-3.
Conveyed the utility model discloses a kind of automatic projection welding positioning guide mechanism of bolt, including by automatic conveying equipment
Bolt 1, for bolt 1 position guiding push rod 2 and stamping holes 3, it is described guiding push rod 2 be arranged at the stamping holes 3
Lower section, the guiding push rod 2 drive its lower movement in vertical direction by drive device, and the guiding push rod 2 moves up
When pass through stamping holes 3, this case is positioned by scalable guiding push rod 2 to bolt 1, when being oriented to push rod 2 and stretching out, by stamping holes
3 lower section through complete stamping holes 3 position, be oriented to push rod 2 shrink when, be placed on be oriented to push rod 2 on bolt 1 with therewith to
Lower movement, is exactly into stamping holes 3, realizes that stamping holes 3 and the centering of bolt 1 are welded, simple in construction, enables to metal plate
The centering rate of accuracy reached of hole 3 and bolt 1 is to absolutely, and the automatic conveying equipment of bolt is prior art in this case.
Installation process：It is directed to set 7 to be set on the open top inwall of sleeve 5, is oriented to push rod 2 and is put by the lower section of sleeve 5
Enter in sleeve 5, by cylinder 6 below sleeve 5, and the piston rod of cylinder 6 is inserted by the bottom opening of sleeve 5 and is oriented to for driving
Set 7 does stretching motion in the open top of sleeve 5；The course of work：Source of the gas connects with the first tracheae 61 of cylinder 6, the piston of cylinder 6
Bar moves up the end for being directed to push rod 2 by the release sleeve 5 of guide sleeve 7, is oriented to push rod 2 and is passed through by the lower section of stamping holes 3, together
When bolt 1 placed it in by automatic conveying equipment and be oriented to the top of push rod 2 and after contacting while decline, bolt 1 is
It can accurately fall into stamping holes 3, then realize that stamping holes 3 are welded with the centering of bolt 1, source of the gas and cylinder 6 after welding
Second tracheae 62 connects so that the piston rod of cylinder 6 moves down, and is directed to push rod 2 and shrinks back in sleeve 5.
The external diameter for being oriented to push rod 2 is not more than the aperture of the stamping holes 3, it is ensured that metal plate can be passed through by being oriented to push rod 2
Hole 3, while the diameter and collapsing length for being oriented to push rod 2 can also be changed, the spiral shell of all models can be promoted the use of
It is very with practical value on bolt and other similar structures.
What the drive device included being vertically arranged is used to be set with the sleeve 5 for being oriented to push rod 2, and the sleeve 5 is fixed on shifting
On dynamic support, the open top of the sleeve 5 is stretched for being oriented to push rod 2, and the bottom opening of the sleeve 5 is used for cylinder 6
Piston rod is inserted, and the first tracheae 61 connected with source of the gas, the side wall top of the cylinder 6 are provided with below the side wall of the cylinder 6
Provided with the second tracheae 62 connected with source of the gas, the present embodiment is existed by the way that sleeve 5 is fixed on mobile support by mobile support
X, when the movement in y-axis ensures that be oriented to push rod 2 is stretched out by sleeve 5, stamping holes 3 can be passed through, complete the positioning of stamping holes 3.
The open top inwall of the sleeve 5 is provided with guide sleeve 7, the internal diameter of the guide sleeve 7 and the guiding push rod 2
External diameter it is identical；Formed with limiting section 21 on the guiding push rod 2, the limiting section 21 is in cylindrical structural, the limiting section
21 diameter of section is more than the external diameter of the guiding push rod 2, by setting guide sleeve 7 to coordinate with limiting section 21, it is ensured that guiding pushes away
