Abstract
The utility model discloses a floated positioning pin mechanism which comprises a pin seat (1), wherein a bushing (2) is arranged in the pin seat (1); a chassis (4) located in the bushing (2) is arranged on a positioning pin (3), and one end of the positioning pin (3) is located at the outer part of the pin seat (1). The floated positioning pin mechanism is characterized in that a gap with the range of +/-D (the diameter of the positioning pin) exists between the bushing (2) and the pin seat (1). The floated positioning pin mechanism which is applied in an automobile welding production line can be used for automatically correcting the positioning location and making up for the deviation of a positioning hole caused by rebounding or stamping deformation of a stamping piece.
Description
Technical field
The utility model relates to a kind of detent mechanism, and the unsteady dowel mechanism of position location can be adjusted, be revised to especially a kind of being applied in during the automobile frame automation is welded automatically.
Background technology
Alignment pin is one of aid indispensable in the automobile welding and assembling clamp, is generally fixed or telescopic, common alignment pin and requires must be maintained fixed in the part loading process, could guarantee accurate positioning like this.But some special situations are arranged: because stamping parts bounce-back or distortion in practical position work, often make the position of locating hole have certain deviation, when needs position two workpiece simultaneously, the position location of one of them need be consistent with another part, just it can't be adjusted to suitable position if use traditional fixed or telescopic alignment pin like this, even if adjust, also need the operator to expend a large amount of work.For these reasons, present many automobile production producer can only utilize the mode of artificial location, has seriously influenced production efficiency.Therefore need a kind of novel dowel mechanism that can address the above problem now.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, a kind of being applied in the car body welding producing line proposed, can remedy because the locating hole deviation that causes is out of shape in stamping parts bounce-back or punching press, can revise the unsteady dowel mechanism of position location automatically.
Concrete solution of the present utility model is: a kind of unsteady dowel mechanism, comprise key seat 1, be provided with lining 2 in the key seat 1, the alignment pin 3 that one end is positioned at key seat 1 outside is provided with chassis 4, chassis 4 is positioned at lining 2, it is characterized in that: have the gap between described lining 2 and the key seat 1, the magnitude range in gap is: ±
D(alignment pin diameter).
The utility model is compared with prior art, has following advantage:
This device simple in structure, design ingenious, it can remedy because of stamping parts bounce-back or punching press and be out of shape caused locating hole deviation, do not need manually-operated just can in having the locating hole of certain error, locate automatically, can revise the location of part in deviation pore radius scope voluntarily, save a large amount of manually-operateds, improved production efficiency, thereby reduced the production cost of enterprise.Therefore we can say that this device has possessed multiple advantage, be particularly suitable in the automobile production industry, applying that its market prospects are more wide.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the user mode schematic diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1 and Figure 2: a kind of unsteady dowel mechanism, comprise a key seat 1 as the basis, key seat 1 is provided with connector, can say that by it key seat 1 and drive unit (as cylinder) couple together, in key seat 1, be provided with lining 2, be provided with alignment pin 3 in the key seat 1, one end of alignment pin 3 is positioned at key seat 1 outside, its head is coniform, the other end is provided with chassis 4, chassis 4 is arranged in the lining 2, and has a gap between lining 2 and key seat 1, and the big or small span in this gap is: ±
D, wherein D is the diameter of alignment pin 3.
The course of work of the unsteady dowel mechanism of the utility model embodiment is as follows: in use, generally the unsteady dowel mechanism with a plurality of versions is connected with connecting plate 5 by connector, connecting plate 5 is connected (cylinder 6 as shown in Figure 2) with drive unit, when needs position sheet material, cylinder 6 drives connecting plate 5, drive all unsteady dowel mechanism motions on it, enter locating hole on the sheet material until the termination of all alignment pins 3.
If sheet material is because distortion to a certain degree takes place in the punching press bounce-back, there is certain error in size between each locating hole, alignment pin 3 is in entering the process of locating hole, owing to there is a gap between key seat 1 and the lining 2, therefore alignment pin 3 can be along the contour motion of locating hole, until entering fully in the locating hole, and coaxial chassis 4 of this moment and alignment pin 3 and the lining 2 that matches with it also can relatively move with key seat 1, to adapt to locating hole, all enter the locating hole of sheet material when all alignment pins 3 after, location work is finished, and carries out subsequent processing.
When to after the machining of sheet material, cylinder 6 drives connecting plates 5 counter motions, and all alignment pins 3 are extracted out from locating hole, change a plate material parts to be processed, repeat above-mentioned action, realize locating.
Claims (1)
