Description

Technical Field

[0001] The utility model relates to the technical field of flanging and pressing shafts, in particular to a flanging and pressing shaft device for workpieces. Background Technique

[0002] The flanging and pressing shaft device is a device that flanges a workpiece by lining, and the process is flanging and pressing the shaft. Then, rivets are pressed into the inside of the bracket and the swivel arm lining to improve the efficiency of pressing the rivets, thereby greatly improving the production efficiency of the workpiece.

[0003] The traditional device for externally flanging a workpiece on a machine includes two transition disks. At least two positioning pins for inserting into the positioning holes on the workpiece are arranged on the transition disks. When flanging, a manipulator is used to take the workpiece from the fixture of the machine tool, place the workpiece on the first transition disk, and insert the positioning pins on the first transition disk into the corresponding positioning holes on the workpiece to position the workpiece on the first transition disk. Then, the second transition disk is covered on the upper surface of the workpiece, and the positioning pins of the second transition disk are inserted into the corresponding positioning holes on the workpiece. Then, the first transition disk, the workpiece, and the second transition disk are integrally flipped so that the second transition disk is located below the workpiece and the first transition disk is located above the workpiece. At this time, the flanging of the workpiece is completed. The first transition disk is removed, and the manipulator is used again to grab the workpiece and place it on the fixture of the machine tool.

[0004] However, the existing flanging equipment has a complex structure and does not have an automatic rivet removal mechanism, resulting in inconvenient rivet removal, which affects the efficiency of flanging and pressing the shaft.

[0028] In summary, for the flanging and pressing equipment for workpieces, during use, the working state is divided into manual and automatic. Select the workpiece type, and check whether the pressing cylinder 5 has risen in place, whether the transverse movement cylinder 28 has retracted in place, and whether the corner cylinder 20 has extended in place. Place the workpiece turntable or bracket on the positioning block 18 at the position corresponding to the workpiece. Only place one piece at a time. When the proximity switch detects a workpiece, the corresponding light on the screen lights up. At the same time, place the rivet on the rivet positioning shaft 15. When the proximity switch detects a rivet, the corresponding light on the screen lights up. When the installation light curtain has no obstruction, the three-color light is green. The operator presses the start button 10 with both hands. The corner cylinder 20 retracts and presses down in place, and the detection switch lights up. The workpiece is clamped. The corner cylinder 20 extends and retracts, and single-step operations can be performed on the screen in the manual state. After the workpiece is clamped, the pressing cylinder 5 drives the transverse movement cylinder 28, the electromagnetic rivet suction head 29, and the flanging shaft 30 to move downward. When it moves in place, flanging and rivet taking are performed simultaneously. When the switch detects that the cylinder has descended in place, a time delay of 0 - 1 second is set (the delay time can be modified on the screen). The pressing cylinder 5 drives the above mechanisms to rise. When it rises in place, the detection switch sends a signal. The pressing cylinder 5 rises and descends, and single-step operations can be performed on the screen in the manual state. After the pressing cylinder 5 rises in place, the transverse movement cylinder 28 drives the electromagnetic rivet suction head 29 and the flanging shaft forward. When the electromagnetic rivet suction head 29 moves above the positioning block 18 and the cylinder extends in place, the detection switch detects the position. The transverse movement cylinder 28 extends and retracts, and single-step operations can be performed on the screen in the manual state. After the transverse movement cylinder 28 extends in place, the pressing cylinder 5 drives the transverse movement cylinder 28, the electromagnetic rivet suction head 29, and the flanging shaft 30 to move downward again, and at the same time presses the rivet into the workpiece. When the pressing cylinder 5 descends in place, the detection switch detects the position, and a time delay of 0 - 1 second is set (the delay time can be adjusted on the screen). The pressing cylinder 5 drives the above mechanisms to rise. When it rises in place, the detection switch sends a signal. After the pressing cylinder 5 rises in place, the transverse movement cylinder 28 drives the electromagnetic rivet suction head 29 and the flanging shaft 30 to move backward. When the cylinder retracts in place, the detection switch detects the position. The corner cylinder 20 rotates and extends. When it extends in place, the detection switch lights up, and the equipment operation is completed. The worker takes out the finished product, puts in the workpiece and the rivet again, and enters the third-step cyclic operation process. When an emergency occurs, press the emergency stop button 11 or touch the display screen. All components remain in their current positions, switch to the manual mode, perform single-step operations on each mechanism, return to the initial state, remove the danger, reset the emergency stop button 11 and the display screen alarm, and then operate the equipment again.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
