Description

A flip positioning structure

Technical Field

The utility model relates to the technical field of flip positioning, in particular to a flip type positioning structure.

Background Art

The main function of the flip positioning structure is to quickly and accurately place the workpiece on the equipment and fix the workpiece in a precise position in the fixture by clamping it with a clamp. This positioning method helps to improve production efficiency because loading can be carried out at one station while processing is carried out at another station without interfering with each other. In addition, by limiting the degree of freedom of the workpiece, it can be ensured that the workpiece will not shift during the processing process, thereby maintaining the original positioning accuracy.

For example, the Chinese utility model patent with the publication number of CN218426974U discloses a flip-type reference positioning structure, including a fixed seat and a support column, the top of the fixed seat is provided with a movable carrier plate, the bottoms of the two ends of the fixed seat are respectively welded and fixed with mounting plates, the internal active connection of the support column is provided with a bidirectional lead screw, and the top and bottom ends of the outside of the bidirectional lead screw are respectively threadedly connected with nuts. The flip-type reference positioning structure is provided with a positioning knob, a positioning block, a bidirectional lead screw, a nut, a connecting block and a limit groove. When in use, the positioning knob is rotated, and the positioning knob drives the bidirectional lead screw to rotate. The bidirectional lead screw will simultaneously drive two sets of nuts through the threaded connection, so that the nut drives the positioning block to move in opposite directions through the connecting block, thereby clamping and positioning the workpiece through the positioning block, which is convenient for fast clamping and positioning of workpieces of different specifications, and is more convenient to use. It solves the problem that it is inconvenient to quickly clamp and fix workpieces of different specifications and it is not convenient to use. The cylinder will drive the telescopic rod to extend and retract, and the telescopic rod will push and pull one side of the supporting column, so that the supporting column will flip with the supporting block as the fulcrum, so that the workpiece can be automatically flipped and adjusted.

In the above technical solution, the telescopic rod is driven to extend and retract by the cylinder, so that the workpiece is automatically flipped and adjusted in position. However, after the adjustment is completed, there is no positioning measure to limit the stability of the angle. The stability of the length of the telescopic rod is achieved only by relying on the pressure of the cylinder. For the cylinder, it is easy to be damaged due to long-term force. In addition, there is no limit device. During the processing, the flipping angle is prone to deviation, which affects the processing accuracy of the workpiece.

The utility model realizes that when the flip positioning structure is used, the synchronous motor drives the bidirectional screw rod to rotate, and the screw nut converts the rotational motion of the bidirectional screw rod into linear motion, so as to realize the lifting and lowering of the screw nut.

At this time, the reset spring is subjected to tension, and the magnetic block is magnetically fixed to one side of the positioning plate by magnetic force. The position of the guide rod is fixed by magnetic force. Since the guide rod is fixedly connected to the positioning shell, the angle of the positioning shell is limited, which prevents the problem of angle deviation during processing and ensures accurate and stable processing.

The utility model provides a technical solution: a flip-type positioning structure, including: a base plate 1 and an electric hydraulic rod 6, an electric slide rail 2 is provided on the top of the base plate 1, a slide plate 3 is provided above the electric slide rail 2, bearing seats 4 are provided on both sides of the top of the slide plate 3, a positioning shell 5 is rotatably provided between the bearing seats 4, an electric hydraulic rod 6 is provided between one side of the positioning shell 5 and the slide plate 3, guide rods 9 are provided on both sides of the outer wall of the positioning shell 5, a positioning plate 7 is provided on the outer wall of the bearing seat 4, an arc groove 8 is opened inside the positioning plate 7, one end of the guide rod 9 is located inside the arc groove 8, a connecting seat 10 is provided at one end of the guide rod 9, an electromagnet 11 is provided at the bottom of the connecting seat 10, and the center of the arc groove 8 is on the same horizontal line as the axis of the bearing seat 4. By extending and retracting the electric telescopic rod 6, the positioning shell 5 and its components are driven to rotate around the axis of the bearing seat 4. During the rotation, the guide rod 9 and its components will also rotate in the arc groove 8. When the rotation is completed and the angle needs to be fixed, the electromagnet 11 is started to generate a magnetic force, which is directly adsorbed on the positioning plate 7. At the same time, the magnetic force will act on the magnetic block 13, driving the magnetic block 13 to slide on the guide rod 9. At this time, the reset spring 12 is subjected to tension, and the magnetic block 13 is magnetically fixed to one side of the positioning plate 7 by magnetic force, and the position of the guide rod 9 is fixed by magnetic force.

Bidirectional screws 17 are rotatably arranged on both sides of the positioning housing 5, and screw nuts 16 are arranged between the bidirectional screws 17. There are two screw nuts 16, which are respectively arranged at the two ends of the bidirectional screw 17. A clamping rod 15 is arranged on one side of the screw nut 16. A synchronous motor 14 is arranged on the top of the positioning housing 5, and one end of the output shaft of the synchronous motor 14 is fixedly connected to one end of the bidirectional screw 17. The bidirectional screw 17 is driven to rotate by the synchronous motor 14, and the rotational motion of the bidirectional screw 17 is converted into linear motion by the screw nut 16 to realize the lifting and lowering of the screw nut 16. Since it is a bidirectional screw 17, when it rotates, the screw nuts 16 with different thread directions can be moved away or close at the same time, thereby realizing the clamping and loosening of the clamping rod 15, and realizing the clamping or removal of the workpiece.

A return spring 12 is provided on the outside of the guide rod 9, and a magnetic block 13 is provided at one end of the return spring 12.

When the flip positioning structure is used, the bidirectional screw 17 is driven to rotate by the synchronous motor 14, and the rotational motion of the bidirectional screw 17 is converted into linear motion by the screw nut 16 to realize the lifting and lowering of the screw nut 16. Since it is a bidirectional screw 17, when it rotates, the screw nuts 16 with different thread directions can move away from or close to each other at the same time, thereby realizing the clamping and loosening of the clamping rod 15, and realizing the clamping or removal of the workpiece;

By extending and retracting the electric telescopic rod 6, the positioning shell 5 and its components are driven to rotate around the axis of the bearing seat 4. During the rotation, the guide rod 9 and its components will also rotate in the arc groove 8. When the rotation is completed, when the angle needs to be fixed, the electromagnet 11 is started to generate a magnetic force through the electromagnet 11, which is directly adsorbed on the positioning plate 7. At the same time, the magnetic force will act on the magnetic block 13, driving the magnetic block 13 to slide on the guide rod 9. At this time, the reset spring 12 is subjected to tension, and the magnetic block 13 is magnetically fixed to one side of the positioning plate 7 through magnetic force, and the position of the guide rod 9 is fixed through magnetic force. Since the guide rod 9 is fixedly connected to the positioning shell 5, the angle of the positioning shell 5 is limited, which prevents the problem of angle deviation during processing and ensures accurate and stable processing.
