Description

Technical Field

[0001] This utility model relates to the field of production line positioning tooling technology, specifically a rotary station tooling for a serial stamping production line. Background Technology

[0002] Currently, stamping production lines are mainly serial stamping. Serial stamping automation includes six-axis robots, four-axis robotic arms, and other types of robotic arms used for the automated handling of parts on the entire line. However, when four-axis robotic arms handle parts between presses on a stamping production line, they have few degrees of freedom and cannot change the angle of the vertical material flow direction. This severely limits the development of stamping dies, as they can only handle parts without changing the angle of the vertical material flow direction, reducing the flexibility of die matching on the production line. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rotary workstation fixture for a tandem stamping production line, which overcomes the limitation of existing four-axis robotic arms being unable to change the angle of the vertical material flow direction when handling parts between presses in a stamping production line.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotary station tooling for a tandem stamping production line, comprising: A pair of bushings are fixedly installed at the center of the bottom frame along its length; A rotating frame is fixedly provided with a rotating shaft at its center along its length direction. The rotating shaft is rotatably engaged with a pair of bushings. A crossbar is fixedly provided inside the rotating frame and on one side of the rotating shaft. A cylinder, the bottom of which is hinged to the bottom frame, and the end of which is hinged to the crossbar; Several extension rods are adjustablely mounted on the four sides of the flip frame and extend outward from the sides; Each of the extension rods is equipped with an L-shaped support plate, the upper side of which is inclined outward.

[0005] Preferably, a support block made of rubber is fixedly installed inside the L-shaped support plate.

[0006] Preferably, a pipe clamp is detachably connected to the bottom of the L-shaped support plate. The pipe clamp is clamped to one end of the extension rod, and the position of the pipe clamp can be adjusted along the length direction of the extension rod.

[0007] Preferably, the other end of the extension rod is detachably connected to a second tube clamp, which is clamped onto the frame of the flip frame and can be adjusted in position along the length of the frame.

[0008] Preferably, a plurality of ear plates are fixedly provided at the bottom of the base frame.

[0009] Preferably, multiple lifting hooks are fixedly installed on the bottom frame.

[0010] This utility model provides a rotary workstation fixture for a tandem stamping production line, which has the following advantages: The rotation of the flipping frame is achieved by lifting with a cylinder, changing the angle of the stamped part in the vertical material flow direction. This allows for precise matching of the stamped part's gripping angle with the loading / unloading robot, thereby shortening the production cycle, improving overall efficiency, and significantly overcoming the limitations of four-axis robotic arms in tandem stamping production lines. It also enables greater flexibility and diversity in the development of molds for four-axis robotic arm tandem stamping lines. Through the cooperation of pipe clamp one and pipe clamp two, the position and tilt angle of the extension rod on the flipping frame, as well as the position adjustment of the L-shaped baffle on the extension rod, are achieved. Multiple adjustable L-shaped baffles form a support and limiting frame that matches the workpiece, ensuring the repeatability and positioning accuracy of the workpiece. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Please see Figures 1-3 This utility model provides a technical solution: a rotary station tooling for a tandem stamping production line, comprising: A pair of bushings 2 are fixedly installed at the center of the bottom frame 1 along its length direction; A rotating frame 4 is fixedly provided with a rotating shaft 3 at the center along its length direction. The rotating shaft 3 is rotatably engaged with a pair of bushings 2. A crossbar 5 is fixedly provided inside the rotating frame 4 and on one side of the rotating shaft 3. Cylinder 6, with its cylinder body hinged to the bottom frame 1 and its piston rod hinged to the crossbar 5, can drive the tilting frame 4 to rotate around the axis of the rotating shaft 3 when the piston rod of cylinder 6 extends or retracts. Several extension rods 7 are installed in adjustable positions on the four sides of the flip frame 4 and extend outward from the sides; L-shaped trays 8 are mounted on each of the extension rods 7 in an adjustable position. The L-shaped trays 8 on the multiple extension rods 7 are used to place stamped parts. The edges of the stamped parts can abut against the sides of the L-shaped trays 8. The upper part of the sides of the L-shaped trays 8 is inclined outward to facilitate the placement of stamped parts.

[0015] As an embodiment of this utility model, a support block 9 made of rubber material is fixedly provided inside the L-shaped support plate 8 to avoid rigid contact between the stamped part and the L-shaped support plate 8 when placing it.

[0016] As an embodiment of this utility model, the bottom of the L-shaped support plate 8 is detachably connected to a pipe clamp 10, which is clamped at one end of the extension rod 7. By loosening and re-locking the pipe clamp 10, the position of the L-shaped baffle 8 along the length of the extension rod 7 can be adjusted to adapt to stamped parts of different shapes.

[0017] As an embodiment of this utility model, the other end of the extension rod 7 is detachably connected to a second pipe clamp 11, which is clamped on the frame of the flip frame 4. By loosening and re-locking the second pipe clamp 11, the position of the extension rod 7 along the length of the frame of the flip frame 4 can be adjusted. In addition, since the extension rod 7 is connected to the flip frame 4 through the second pipe clamp 11, the tilt angle of the extension rod 7 can be adjusted through the second pipe clamp 11. By selecting a suitable angle and locking it, the height adjustment of the L-shaped baffle 8 can be realized simultaneously.

[0018] As an embodiment of the present invention, the bottom of the base frame 1 is fixedly provided with a plurality of ear plates 12, so as to fix the base frame 1 at a predetermined work position on the production line and ensure its spatial positional relationship with the loading and unloading robotic arm.

[0019] As an embodiment of this utility model, a plurality of lifting hooks 13 are fixedly provided on the bottom frame 1 to facilitate the lifting and transportation of the bottom frame 1.

[0020] The working principle and usage process of this utility model are as follows: Before use, adjust the positions of the extension rod 7 and the L-shaped support plate 8 according to the shape of the stamped part. After adjustment, the stamped part is placed on multiple L-shaped baffles 8 by the loading robot arm, which support and limit its movement. After placement, the cylinder 6 is activated to push the flipping frame 4 and the stamped part on it to rotate around the rotating shaft 3 to a predetermined angle. At this time, the spatial posture of the stamped part is adjusted so that it can be precisely matched with the gripping angle of the unloading robot arm in the subsequent station, and then it can wait for the unloading robot arm to grip it.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
