Abstract
The utility model relates to an automatic change and equip, specifically a two round pins in one side location frock of large-scale work piece, which comprises a fixing plate and i, the centre bore is seted up in order to dodge three-jaw centering chuck set firmly first locating pin on the fixed plate, at every the centering clamp finger sets firmly on the jack catch of three-jaw centering chuck, the upper surface that the centering clamp finger sets firmly spacer pin, locating piece, it is three discoid limiting plate is placed to the upper surface that the centering clamp finger, radial, corresponding to of limiting plate three slotted hole is seted up to the position of spacer pin. Compared with the prior art, the utility model discloses greatly reduced the location demand, not lose positioning accuracy again.
Description
Technical Field
The utility model relates to an automatic equipment specifically is a two round pin location frocks of one side of large-scale work piece.
Background
A one-surface two-pin positioning tool is a common positioning mode in machining. However, for the automated processing of large-sized workpieces, on one hand, the size precision of the positioning holes on the workpieces cannot be guaranteed, and on the other hand, the assembly precision of robots and robots cannot be guaranteed, so that the existing one-surface two-pin positioning tool cannot adapt to the automated processing of large-sized workpieces.
SUMMERY OF THE UTILITY MODEL
For solving the above-mentioned technical problem, the utility model provides a two round pin location frocks of one side of large-scale work piece, the technical scheme who takes is:
the utility model provides a two round pins in one side location frock of large-scale work piece, includes the fixed plate, the fixed plate is seted up the centre bore in order to dodge three-jaw centering chuck set firmly first locating pin on the fixed plate, every set firmly the centering on the jack catch of three-jaw centering chuck and press from both sides the finger, the upper surface that the centering pressed from both sides the finger sets firmly spacer pin, locating piece, it is three discoid limiting plate is placed to the upper surface that the centering pressed from both sides the finger, radial, corresponding to of limiting plate three slotted hole is seted up to the position of spacer pin.
Furthermore, a plurality of compression rotary oil cylinders are uniformly and fixedly arranged on the fixing plate around the center of the center hole.
Compared with the prior art, the utility model discloses utilize centering chuck, centering to press from both sides to indicate "second locating pin" that forms one side two round pins location, and "second locating pin" can stretch out and draw back, is equivalent to "second locating pin" clearance very big, only needs to accomplish the cooperation of another one fixing location round pin during consequently the robot material loading, greatly reduced the location demand, follow the shrink of three-jaw centering chuck behind the material loading, "second locating pin" accurate return, do not lose positioning accuracy again.

Detailed Description
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
In the description of the present invention, unless otherwise specified, "a plurality" means two or more unless explicitly defined otherwise.
In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
The present invention will be described in further detail with reference to the accompanying drawings.
The one-surface two-pin positioning tool for the large workpiece shown in fig. 1-2 includes a fixing plate 200, wherein the fixing plate 200 is provided with a central hole 201 to avoid the three-jaw centering chuck 100, the fixing plate 200 is fixedly provided with a first positioning pin 300, each jaw of the three-jaw centering chuck 100 is fixedly provided with a centering finger 401, the upper surface of each centering finger is fixedly provided with a limiting pin 402 and a positioning block 405, the upper surface of each centering finger is provided with a disc-shaped limiting plate 403, and the radial direction of each limiting plate 403 and the position corresponding to the limiting pin 402 are provided with three long circular holes 404. And 6 compression rotary oil cylinders 500 are uniformly and fixedly arranged on the fixing plate 200 around the center of the center hole 201.
The limiting plate is used for limiting the stroke of the centering clamp finger, the centering chuck and the centering clamp finger replace the other pin shaft in the two pins on one surface, the limiting pin on the centering clamp finger is matched with the long round hole on the limiting plate, so that the centering clamp finger moves in a limited range, and when the centering clamp finger moves to the limit position on one side, the positioning blocks on the three centering clamp fingers form new positioning pins to complete the positioning of a workpiece.
Before the operation material loading, the centering chuck moves to the loose end, and the robot carries out the material loading, because of the chuck stroke is great, is equal to that the work piece is great with one of them round pin axle clearance, and the robot material loading only needs to accomplish the cooperation of another fixed position round pin. After the feeding is finished, the centering chuck drives the centering clamp fingers to move, and the long holes in the limiting plates limit the centering clamp fingers to move to fixed positions, so that the workpieces are positioned.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the invention is not limited to the embodiments described herein, but is capable of other embodiments with obvious modifications, variations, and equivalents without departing from the scope of the invention. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments by the technical entity of the present invention all still belong to the protection scope of the technical solution of the present invention.
