The utility model provides a kind of easy to use, effective alignment pin that has jaw, is used for the location of automobile welding assembly.
A kind of jaw pin retention mechanisms that is used for automobile welding comprises bearing and is fixed on alignment pin on this bearing that described alignment pin has perforation gathering sill radially, is provided with along alignment pin to extend radially out or the location hook of this gathering sill of retraction.
Can compress the automobile component that needs the location when location hook stretches out gathering sill, during location hook retraction gathering sill, automobile component can break away from from alignment pin.
In order to realize that location hook can adopt multiple type of drive along alignment pin moving radially, as preferably, be provided with jaw, described jaw comprises:
Fork;
Described location hook is fixed on an end of fork;
Connecting rod, an end of connecting rod is hinged by an end that has location hook of first rotating shaft and fork, and the other end of connecting rod is hinged by second rotating shaft and bearing;
Cylinder, its cylinder barrel and bearing are fixed, and the end away from location hook of piston rod and fork is hinged.
Air cylinder driven fork, fork can drive described location hook along alignment pin moving radially.
As preferably, the piston rod of described cylinder is parallel to the axial arranged of described alignment pin.
As preferably, the bottom of described bearing is provided with support column.Can adjust the height of support column as required.
Described bearing top has a shape carriage, and this shape carriage is made of horizontal top board and two risers that are connected the top board both sides, has pin-and-hole on the wherein said top board, and the top of described alignment pin passes this pin-and-hole and fixes with respect to top board.
Described two riser correspondences be provided with circular hole, the two ends of described first rotating shaft are positioned at corresponding circular hole.Described circular hole cooperates with the gap between two ends of first rotating shaft.The two ends of first rotating shaft can be in circular hole appropriate exercise, to cooperate moving of location hook.
The corresponding position of the gathering sill of described top board and alignment pin has the installation gap, and when location hook was installed, location hook entered into the gathering sill of alignment pin by this installation gap.
The sidewall of described top board has the locking screw that is communicated with the pin-and-hole inwall, can the locking positioning pin by clamping screw.
It is simple in structure easy to use that the utility model is used for the jaw pin retention mechanisms of automobile welding, and utilizing movably, location hook can effectively solve the problem that ghost formula parts are difficult to compress the location.Utilizing lever principle can clamp by little cylinder puts in place.Effectively solved compressing and locating of little locating hole parts.Can also the size of each building block be done corresponding adjustment according to the size in different automobile types aperture.

The specific embodiment
Referring to accompanying drawing, the utility model is a kind of to be used for the jaw pin retention mechanisms of automobile welding, comprises bearing 1 and is fixed on alignment pin 2 on this bearing, and the bottom of bearing 1 is provided with support column 3, can adjust the height of support column 3 as required.
Alignment pin 2 has perforation gathering sill 18 radially, is provided with jaw 4, and jaw 4 comprises:
Fork 6;
Be fixed on the location hook 5 of an end of fork 6, location hook 5 is arranged in gathering sill 18;
Connecting rod 7, an end of connecting rod 7 is hinged with an end that has location hook 5 of fork 6 by first rotating shaft 8, and the other end of connecting rod 7 is hinged with bearing 1 by second rotating shaft 9;
Cylinder 11, its cylinder barrel and bearing 1 are fixing, and piston rod 10 is hinged with the end away from location hook 5 of fork 6, and piston rod 10 is parallel to the axial arranged of alignment pin 2.
