The first overturning arm is provided with a connecting support, the second limiting block is arranged on the connecting support, and the second overturning arm is provided with a limiting structure matched with the second limiting block.

The first overturning arm is perpendicular to the stretching direction of the cylinder when in a vertical overturning state, the second overturning arm is perpendicular to the first overturning arm when in a horizontal overturning state, and the cylinder, the first overturning arm and the second overturning arm are integrally C-shaped.

And the positioning pin and the rotating point of the pressing arm of the clamping cylinder are positioned on the same horizontal line.

The positioning pin is arranged at the head end of the second overturning arm through a pin support.

And a sensor is arranged on the second overturning arm.

Advantageous effects

The utility model discloses wholly be the C type when turning over and pressing the orientation state, can realize 180 through the two-stage upset and open, it is big to open the angle, and the whole vertical height who opens back equipment is low, is favorable to reducing the business turn over height of work piece level upper and lower piece, avoids carrying with the work piece and produces the interference, and equipment is turned over from the location station simultaneously, is favorable to avoiding taking place to interfere with other processing technology (if border technology) equipment of work piece. The utility model discloses turn over the level of pressing the state and the second upset arm and turn over the state and fix a position the vertical state of pressing of first upset arm and second upset arm through first stopper and second stopper respectively, the part structural arrangement is compact, has guaranteed high positioning accuracy.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

The positioning mechanism for the secondary turnover pin shown in fig. 1 and 2 comprises a first fixed support 1, a cylinder 2, a second fixed support 3, a first turnover arm 4, a clamping cylinder 5, a second turnover arm 6 and a positioning pin 7.

The cylinder 2 is horizontally arranged, and the tail end of the cylinder is hinged with the first fixed support 1. The second fixing support 3 is arranged above the cylinder 2 and is perpendicular to the telescopic direction of the cylinder 2. The bottom of the first turnover arm 4 is hinged to a telescopic rod of the cylinder 2, the first turnover arm 4 is connected with the second fixed support 3 through a hinge support pin 8 above a hinged point of the telescopic rod, and the first turnover arm 4 can be pushed to rotate along the hinge support pin 8 through telescopic driving of the cylinder 2. Above the hinge support pin 8, be equipped with first stopper 9 between first upset arm 4 and the second fixing support 3, when vertical state was overturned to first upset arm 4, first upset arm 4 was fixed a position through first stopper 9, guaranteed that first upset arm 4 is perpendicular with the flexible direction of cylinder 2.

The clamping cylinder 5 is mounted on the first flipping arm 4 and the second flipping arm 6 is mounted on the press arm of the clamping cylinder 5. Connecting support 11 is installed at the top of first upset arm 4, and H type second stopper 10 is installed at connecting support 11's top, and second upset arm 6 corresponds the position both sides of second stopper 10 and is equipped with the recess for second upset arm 6 can be with the nested cooperation of recess at second stopper 10 top. The pressing arm is driven to swing through the clamping cylinder 5 to drive the second turnover arm 6 to overturn, when the second turnover arm 6 overturns to be perpendicular to the first turnover arm 4, the second turnover arm 6 and the connecting support 11 form positioning through the second limiting block 10, and positioning accuracy is guaranteed.
