The hooked nail pin has a simple structure, has functions of positioning a plate hole and positioning and compressing plates, and can also increase working space of welding.
Description
Technical field
The utility model relates to a kind of auto parts positioning compression hook nail latch structure.
Background technology
General body of a motor car is made of more than 400 stamping parts, and the welding through multiple working procedure finally becomes a vehicle body.When the welding of each station, could weld after all needing fixture to position, the accessory size after guarantee welds like this keeps consistency, so detent mechanism utilization in a large number in the automobile body welding process.
But at present, general detent mechanism is more complicated, the while function singleness, and the weld jig narrow space, during welding, welding gun is easily interfered, thereby affects welding quality, and then the size of the rear parts of impact welding, causes the problems such as all kinds of assemblings of vehicle body and security performance.
Summary of the invention
In order to overcome defects, the utility model provides a kind of auto parts positioning compression hook nail latch structure, and this structure is not only simple, possesses simultaneously two functions of location panel hole and plate positioning compression, can also increase the weld job space.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of auto parts positioning compression hook nail latch structure comprises bearing and is fixedly arranged on alignment pin on this bearing upper end; Vertically be provided with gib head pin in described bearing and alignment pin, this gib head pin comprises the pin body and is located at the compact heap of this pin body upper end, and this compact heap forms downward L-type gib head by a junction and described pin body; Separately be provided with actuating unit, the pin body that this actuating unit can drive described gib head pin moves up and down and described compact heap is retracted and stretch out the lateral surface of described alignment pin.
As further improvement of the utility model, the pin body that described actuating unit can drive described gib head pin moves up and down and described compact heap retracted and the structure of stretching out the lateral surface of described alignment pin is: described actuating unit is a cylinder, the lower end of the described pin body of piston rod upper end connection of this cylinder, described pin body middle part is provided with a kidney slot, the fixed axis activity that separately is provided with is set in described kidney slot, and the two ends of described fixed axis are fixed in described bearing.
As further improvement of the utility model, described gib head pin is two, and is symmetric in described bearing and alignment pin.
As further improvement of the utility model, the piston rod upper end of described cylinder connects the lower end of the pin body of described two gib head pins simultaneously, and described fixed axis is set in the kidney slot of pin body of described two gib head pins simultaneously.
As further improvement of the utility model, be provided with a contiguous block between the piston rod of described cylinder and described pin body.
As further improvement of the utility model, be provided with locating piece below corresponding described compact heap on described bearing upper surface.
As further improvement of the utility model, be provided with pad between described bearing and locating piece.
The beneficial effects of the utility model are: the function that can realize locating panel hole by the alignment pin that is fixedly arranged on the bearing upper end, rise retraction movement by cylinder top simultaneously and realize locating plate clamping opening function, it is not only simple in structure, reliable in function, and can increase the weld job space, promote welding quality.

The specific embodiment
Below in conjunction with description of drawings a kind of preferred embodiment of the present utility model.
As shown in Figure 1, 2, a kind of auto parts positioning compression hook nail latch structure comprises bearing 1 and is fixedly arranged on alignment pin 2 on this bearing upper end; Vertically be arranged with two gib head pins in bearing and alignment pin, this each gib head pin comprises pin body 3 and is located at the compact heap 4 of this pin body upper end, and this compact heap forms downward L-type gib head by a junction and pin body; Separately be provided with a cylinder 5, the piston rod upper end of this cylinder connects respectively the lower end of two pin bodies by contiguous block 10, and two pin bodies middle parts are respectively equipped with a kidney slot 6, and fixed axis 7 activities that separately are provided with are set in two kidney slots, and the two ends of fixed axis are fixed in bearing.Separately be provided with locating piece 8 and pad 9 below corresponding compact heap on bearing, pad can be adjusted as required, guarantees that sheet metal part effectively is pressed on locating piece.
During use, driving two pin bodies by moving up and down of cylinder jacking and retraction moves up and down, wear respectively a fixed axis that is fixed on bearing in kidney slot due to the middle part of two pin bodies, therefore two pin bodies when the motion of cylinder jacking and retraction along the orbiting motion of kidney slot, thereby the compact heap of realizing gib head pin is retracted and is stretched out the alignment pin side.Status architecture schematic diagram when retracting for compact heap as shown in Figure 3A, this moment, cylinder rose to highest point, and fixed axis is positioned at the kidney slot lowermost end of pin body; Be the status architecture schematic diagram of compact heap when opening gradually as Fig. 3 B and 3C, this moment, cylinder was retracted gradually, and the pin body moves down gradually with the spacing of kidney slot; Be the status architecture schematic diagram of compact heap when opening fully as Fig. 3 D, this moment, cylinder piston rod was compressed to the shortlyest, and fixed axis is positioned at the most significant end of the kidney slot of pin body.
