Abstract

The invention discloses an automobile part positioning and pressing hook pin structure, which comprises a support and a positioning pin which is fixedly arranged at the upper end of the support. A hook-head pin is vertically arranged in the support and the positioning pin. The hook-head pin comprises a pin body and pressing blocks which are arranged at the upper ends of the pin body. Each pressing block is connected with the pin body through a connecting part to form a downward L-shaped hook. A power mechanism is additionally arranged, can drive the pin body of the hook-head pin to move up and down and can enable the pressing blocks to retract into and extend out of the external side surface of the positioning pin. The automobile part positioning and pressing hook pin structure has the advantages that not only is the structure simple, but also the hook pin structure has dual functions of plate hole positioning and plate positioning and pressing, and the welding space can be also increased.

Description

Auto parts positioning compression hook nail latch structure
Technical field
The present invention 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 anchor clamps to position, the accessory size after guarantee welds like this keeps consistency, so detent mechanism in a large number utilization in the automobile body welding process.
But present, general detent mechanism is complicated, the while function singleness, and the weld jig narrow space, welding gun is interfered easily during welding, 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 invention provides a kind of auto parts positioning compression hook nail latch structure, 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 present invention 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 the alignment pin that is fixedly arranged 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 that this compact heap forms downward L-type gib head by a junction and described pin body; Other is provided with actuating unit, and the pin body that this actuating unit can drive described gib head pin moves up and down and described compact heap is retracted and stretches out the lateral surface of described alignment pin.
As a further improvement on the present invention, 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 piston rod upper end of this cylinder connects the lower end of described pin body, described pin body middle part is provided with a kidney slot, other is provided with a fixed axis activity and is set in the described kidney slot, and the two ends of described fixed axis are fixed in the described bearing.
As a further improvement on the present invention, described gib head pin is two, and is symmetric in described bearing and alignment pin.
As a further improvement on the present invention, the piston rod of described cylinder upper end 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 a further improvement on the present invention, between the piston rod of described cylinder and described pin body, be provided with a contiguous block.
As a further improvement on the present invention, be provided with locating piece below the corresponding described compact heap on the described bearing upper surface.
As a further improvement on the present invention, between described bearing and locating piece, be provided with pad.
The invention has the beneficial effects as follows: 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 preferred embodiment of the present invention.
As shown in Figure 1, 2, a kind of auto parts positioning compression hook nail latch structure comprises bearing 1 and the alignment pin 2 that is fixedly arranged 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 that this compact heap forms downward L-type gib head by a junction and pin body; Other is provided with a cylinder 5, and 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 part is respectively equipped with a kidney slot 6, and other is provided with a fixed axis 7 activities and is set in two kidney slots, and the two ends of fixed axis are fixed in the bearing.Be provided with locating piece 8 and pad 9 in addition below corresponding compact heap on the bearing, pad can be adjusted as required, guarantees that sheet metal part effectively is pressed on the locating piece.
During use, driving two pin bodies by moving up and down of cylinder jacking and retraction moves up and down, owing to wear respectively a fixed axis that is fixed on the bearing in the kidney slot at 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 such 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 such 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.
