The elastic locating mechanism further comprises a guide rod (4), wherein a hole which is matched with the guide rod (4) is formed in the open locating pin (1). The elastic locating mechanism further comprises a driving mechanism which is used for driving the guide rod (4) to enter or leave the hole in the open locating pin (1). The situation that a plate can be smoothly taken out after welding is accomplished no matter what happens.
Description
Technical field
The utility model belongs to the frock field of being welded, and relates in particular to a kind of elastic locating mechanism.
Background technology
In the frock clamp that use in the workshop that is welded, alignment pin is the main benchmark in body panel location, and alignment pin and plate have the gap of 0.2 millimeter.But when the location, limit by the product design in early stage, often can locating hole occur irregular, locating hole face and Master Datum Plane are not parallel, and perhaps welded plates produces distortion etc. problem.Cause plate pickup difficulty after positioning welding, the workshop workman that is welded requires great effort in operation especially, greatly reduces efficiency.When especially welding the part of longeron class, due to reasons such as plate welding deformations, when being welded the jacking pickup and alignment pin stuck, and cause plate locating hole distortion, and then can't guarantee the precision of weld size.
Just present welding and assembling technics situation, this problem does not obtain effective solution, even if in the workshop that is welded of having produced in batches, the station of a lot of more difficult operations is arranged still.Cause operating personnel can't finish the work in the beat of regulation, caused temporal waste, cause even sometimes and stop line.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of elastic locating mechanism that facilitates pickup.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of elastic locating mechanism, comprise opening alignment pin and location key seat, described opening alignment pin is arranged on location key seat, described opening alignment pin comprises pin and flange, and described pin is provided with the opening that runs through pin; Also comprise guide rod, described opening alignment pin is provided with the hole suitable with guide rod; Also comprise the driving mechanism that enters or leave opening alignment pin mesopore for drive leader.
Described opening alignment pin both sides are provided with locating piece.
Described driving mechanism is cylinder, and described cylinder is connected with guide rod.
The end of described pin is taper, and the end of described guide rod is taper.
Described opening alignment pin, locating piece and location key seat are bolted.
The utility model has the advantage of, change original diameter fixed locating stud into diameter elasticity collapsible alignment pin, can guarantee what situation no matter plate after welding is completed, occur, and can take out smoothly.Guaranteed that not only the station beat is unaffected, can also reduce workman's labour intensity, and guaranteed the precision size of workpiece.

The specific embodiment
Fig. 1 and Fig. 2 are the structural representation of a kind of elastic locating mechanism of the utility model, comprise opening alignment pin 1 and location key seat 3, opening alignment pin 1 is arranged on location key seat 3, and opening alignment pin 1 comprises pin 11 and flange 12, and pin 11 is provided with the opening 111 that runs through pin 11; Also comprise guide rod 4, opening alignment pin 1 is provided with the hole suitable with guide rod 4; Also comprise the driving mechanism that enters or leave opening alignment pin 1 mesopore for drive leader 4.
Locating piece 2 is controlled the excircle dimension of opening alignment pin 1, and when being hit, plays a supportive role.2 locating pieces 2 and opening alignment pin 1 respectively with 2 pins with is connected a bolt and is connected; Guide rod 4 is that precision coordinates with the aperture of opening alignment pin 1, can not shrink when locating plate with the outside dimension that ensures opening alignment pin 1; Opening alignment pin 1 plays the opening contraction; Guide rod 4 is used in conjunction with opening alignment pin 1 effect of playing the location plate.
Use procedure is:
One: guide rod 4 alignment pins rise, and coordinate with opening alignment pin 1, reach the location theoretical position, as shown in Figure 3;
Two: after opening alignment pin 1 diameter reaches the location theoretical value, put the part welding, as shown in Figure 4;
Three: weld complete after, guide rod 4 alignment pins descend, opening alignment pin 1 diameter dwindles thereupon, size narrows down to less than theoretical value, as shown in Figure 5;
Four: the alignment pin size narrows down to less than after theoretical value, and is large with plate gap change, gets final product smooth pickup, as shown in Figure 6.
By when the pickup, shrink opening alignment pin 1 diameter, be 1 ~ 2 millimeter with the gap enlargement of 0.2 millimeter of original alignment pin and plate, thus make plate can because of distortion and alignment pin not stuck, thereby realize smoothly pickup.This scheme is simple in structure, use is flexible and efficient.Especially when longeron class weld parts, can effectively avoid having extended the service life of alignment pin because of the wearing and tearing of plate distortion to alignment pin, the replacement cycle of having reduced spare part, save use cost, and can improve the welding quality of vehicle body.
After adopting such mechanism, change original diameter fixed locating stud into diameter elasticity collapsible alignment pin, can guarantee what situation no matter plate after welding is completed, occur, and can take out smoothly.Guaranteed that not only the station beat is unaffected, can also reduce workman's labour intensity, and guaranteed the precision size of workpiece.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
