Abstract
The utility model discloses a telescopic structure of a locating pin suitable for picking a piece after welding. The telescopic structure of the locating pin suitable for picking the piece after welding includes a thin-type air cylinder. The thin-type air cylinder is connected with a support fixedly. A piston rod matching with the thin-type air cylinder protrudes into an inner hole of the support and is connected with one end of a guide rod disposed in the inner hole of the support. The other end of the guide rod protrudes outside the support. An outer tip of the guide rod is connected with a locating pin. An installation connection bolt is connected to a side face of the support. The telescopic structure of the locating pin suitable for picking the piece after welding is installed on a welding production line through the installation connection bolt. When the locating pin needs to be used for locating a working piece, the piston rod can be driven to move through a pneumatic device, thereby driving the guide rod to protrude out and making the locating pin insert into a locating hole in the working piece. When taking the work piece after welding, the air cylinder drives the guide rod to retract and makes the locating pin return. The action is reliable and the work piece can be picked easily after welding. The working efficiency is high, and the labor strength of works is low, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of alignment pin Collapsible structure that is suitable for welding the back pickup, is particularly useful on the single weld jig alignment pin quantity more than under 2 the situation.
Background technology
At present, along with the sustainable growth of automobile market, each big automobile factory is all strengthening output, the compression productive temp, but automobile factory's welding and assembling production lines percent of automatization is not high, and the many places station is welded as the master with manual work, and resultant is that working strength of workers is big.The location of sheet metal component generally needs major-minor two alignment pins; If n sheet metal component of a soldering cramping apparatus welding; Usually need 2n alignment pin, welding finishes the back because the influence of factors such as material and thickness of slab, and the multilayer sheet metal component causes the frictional force between sheet metal component and the alignment pin sharply to strengthen in various degree distortion; The very inconvenience of back workman's pickup thereby welding finishes; If rough power pickup also very easily destroys the positioning reference hole of workpiece, main cause is that the alignment pin on the present welding production line is fixed more, not flexible.
Summary of the invention
The purpose of the utility model provides the alignment pin Collapsible structure that is suitable for welding the back pickup that a kind of alignment pin is scalable, the location is convenient, the postwelding pickup is easy, enhance productivity, reduce labor intensity, and overcomes the deficiency of prior art.
The alignment pin Collapsible structure that is suitable for welding the back pickup of the utility model; Comprise slim cylinder; Slim cylinder is fixedly connected with bearing, and the piston rod that matches with slim cylinder stretches into the endoporus of bearing and joins with an end of the guide post that is positioned at the bearing endoporus, and the other end of guide post extend out to the outside of bearing; The external end head of guide post is connected to alignment pin, is connected to the installation connecting bolt in the side of bearing.
The alignment pin Collapsible structure that is suitable for welding the back pickup of the utility model, wherein said bearing endoporus is provided with boss, and the step of this boss and guide post below matches, and is fixed with pressing plate in the termination of bearing, and the side step of pressing plate and guide post top matches.
The alignment pin Collapsible structure that is suitable for welding the back pickup of the utility model; Through being installed, connecting bolt is installed on the weld jig; When utilizing alignment pin that workpiece is located as required, can drive piston rod through pneumatic means and move, stretch out thereby drive guide post; Alignment pin is inserted in the locating hole on the workpiece that is welded, thereby realize location workpiece hole.During the postwelding pickup, cylinder drives the guide post retraction, and alignment pin is return, reliable in action, and the postwelding pickup is easy, and production efficiency is high, and labor strength is low, has reduced production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is that sketch map is looked on a left side shown in Figure 1;
Fig. 3 is a schematic top plan view shown in Figure 1;
Fig. 4 is that A-A shown in Figure 1 looks and shows enlarged diagram.
The specific embodiment
Like Fig. 1,2,3, shown in 4: 8 is the slim cylinder that joins with air control unit; Slim cylinder 8 is connected with the bearing 7 of band endoporus through bolt, stretches into the endoporus of bearing 7 with piston rod 9 that slim cylinder 8 matches and is connected through engage thread with an end of the guide post 3 that is positioned at bearing 7 endoporus, and the other end of guide post 3 extend out to the outside of bearing 7; The external end head of guide post 3 is connected to alignment pin 1; On the alignment pin 1 conical surface is arranged, the trip bolt 2 that has been threaded on the guide post 3, the inner termination that fastens screw 2 leans on the conical surface; Make alignment pin 1 have inside axial force to be used for axial limiting, on alignment pin 1, have step to be stuck in the termination of guide post 3.Be connected to adjustment pad 6 in the side of bearing 7 and connecting bolt 10 is installed.Moving axially of guide post 3 is provided with lining 5 between guide post 3 and bearing 7 for ease.
Bearing 7 endoporus are provided with boss, and the step of this boss and guide post 3 belows matches, and through bolt pressing plate 4 is arranged in the termination of bearing 7, and pressing plate 4 matches with the side step of guide post 3 tops, guide post 3 is played the effect of axial limiting.
This structure is installed on the welding production line through connecting bolt 10 is installed, and in the time of need utilizing alignment pin that workpiece is located, can drive piston rod 9 through pneumatic means and move, and stretches out thereby drive guide post 3; Alignment pin 1 is inserted in the locating hole on the workpiece that is welded, and during the postwelding pickup, cylinder drives guide post 3 retractions; Alignment pin 1 is return, reliable in action, the postwelding pickup is easy; Production efficiency is high, and labor strength is low, has reduced production cost.
