Abstract
The utility model discloses a small part positioning mechanism used for a welding fixture air cylinder. The welding fixture air cylinder comprises an air cylinder with a piston rod, and an air cylinder fixing support; the air cylinder is fixed under the air cylinder fixing support; the small part positioning mechanism is connected with the piston rod; and the small part positioning mechanism comprises a connecting rod, a connecting plate, a stamping part positioning supporting block and two positioning pins. According to the small part positioning mechanism used for the welding fixture air cylinder, the connecting rod drives the positioning pins arranged on two sides of the connecting plate to stretch out and draw back by means of the telescopic motion of the piston rod of the air cylinder, waist-shaped open grooves are formed in two ends of the connecting plate, two symmetric positioning surfaces are arranged on joints of the positioning pins and the connecting plate, and therefore anti-rotating effect of anti-rotating pins can be effectively ensured; Meanwhile, the positioning pins are just in surface contact with the connecting plate, so the depth of parallelism of the axes of the positioning pins and the connecting rod is completely controlled by a guide sleeve on the stamping part positioning supporting block; the small part positioning mechanism can effectively ensures that the positioning pins stretch out and draw back, and ensures reliability and accuracy of positioning.
Description
Technical field
The utility model relates to welding equipment, relates in particular to a kind of finding detent mechanism for the weld jig cylinder.
Background technology
The structure of finding location is comparatively compact at present, the locating hole hole heart is apart from less on the part, for guaranteeing that robot has enough spaces when welding, adopt the mode of two alignment pins of an air cylinder driven (is main alignment pin, and is stop pin) to save the anchor clamps space during jig Design.
The mechanism of two alignment pins of existing single air cylinder driven, with bolts between its alignment pin and the connecting plate.Bolt is loosening easily at work on the one hand, causes that rotating or rocking appears in stop pin, can't satisfy the pinpoint requirement of anchor clamps, on the other hand because processing and the rigging error of clamp part parts cause alignment pin to stretch out or to retract easily.
Summary of the invention
The purpose of this utility model provides a kind of for the finding detent mechanism weld jig cylinder, simple and compact for structure, reasonable in design, that effect remarkable, application conveniently has anti-rotating function exactly in order to address the above problem.
The purpose of this utility model is achieved in that
A kind of finding detent mechanism for the weld jig cylinder of the present utility model, described weld jig cylinder comprises cylinder and the cylinder fixed support with piston rod, described cylinder be fixed in described cylinder support bracket fastened under, described finding detent mechanism is connected with described piston rod, described finding detent mechanism comprises connecting rod, connecting plate, stamping parts positioning support bracer and two alignment pins, wherein
The bottom of described connecting plate is connected with the top of described piston rod by connecting rod, and the two ends of described connecting plate have waist type open slot;
Have two through holes on the described stamping parts positioning support bracer, and be equipped with fairlead in this through hole;
Corresponding fairlead is passed respectively in the upper end of described two alignment pins, and the bottom of described two alignment pins is located at respectively on the described connecting plate in the corresponding waist type open slot, on the described alignment pin and be positioned at the locating surface that is provided with two symmetries with the joint of described waist type open slot.
The utility model finding detent mechanism is by the stretching motion of cylinder piston rod, (one is main alignment pin to drive the alignment pin of connecting plate both sides by connecting rod, one for stop pin) stretch out and retract, the two ends of connecting plate have waist type open slot, alignment pin and connecting plate joint are provided with the locating surface of two symmetries, therefore can effectively guarantee the anti-rotation effect of stop pin, alignment pin only has face to contact with connecting plate simultaneously, therefore the depth of parallelism of alignment pin axis and connecting rod is controlled by the fairlead on the stamping parts back-up block fully, can effectively guarantee stretching out and returning of alignment pin, guarantee that the location is precisely reliable.
Description of drawings

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See also Fig. 1, there is shown the finding detent mechanism that the utility model is used for the weld jig cylinder.The weld jig cylinder comprises cylinder 1 and the cylinder fixed support 11 with piston rod 12, cylinder 1 be fixed in cylinder fixed support 11 under, the utility model finding detent mechanism comprises that (one is main alignment pin 5 for connecting rod 2, connecting plate 3, stamping parts positioning support bracer 4 and two alignment pins, one is stop pin 6), wherein:
The bottom of connecting plate 3 is connected with the top of piston rod 12 by connecting rod 2, and the two ends of connecting plate 3 have waist type open slot 31 as shown in Figure 2;
Have two through holes on the stamping parts positioning support bracer 4, and be equipped with fairlead in this through hole;
The upper end of main alignment pin 5 and stop pin 6 is passed corresponding fairlead separately, the bottom of main alignment pin 5 and stop pin 6 is located at respectively in the waist type open slot corresponding on the connecting plate 3 31 (as shown in Figure 2), on main alignment pin 5 and the stop pin 6 and be positioned at waist type open slot 31 joints and be provided with locating surface 7 two symmetries, as shown in Figure 3, the locating surface 7 of these two symmetries fits tightly with the both sides internal groove side wall of waist type open slot 31.
The utility model finding detent mechanism is by the stretching motion of piston rod 12, (one is main alignment pin 5 to drive the alignment pin of connecting plate both sides by connecting rod 2, one for stop pin 6) stretch out and retract, the two ends of connecting plate 3 have waist type open slot 31, alignment pin and connecting plate 3 cooperation places are provided with the locating surface 7 of two symmetries, therefore can effectively guarantee the anti-rotation effect of stop pin 6, alignment pin only has face to contact with connecting plate 3 simultaneously, therefore the depth of parallelism of alignment pin axis and connecting rod 2 is controlled by the fairlead on the stamping parts positioning support bracer 4 fully, can effectively guarantee stretching out and returning of alignment pin, guarantee that the location is precisely reliable.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
