Description

Technical Field

[0001] The utility model relates to the technical field of workpiece rolling and chamfering, in particular to a workpiece rolling and chamfering processing device. Background Art

[0002] The existing workpiece hemming and chamfering device, when in practical use, first manually places the workpiece to be processed on the processing position of the mounting device, then starts the clamping device to fix the workpiece, then starts the hemming mechanism, moves the hemming wheel to the edge position of the workpiece, and then starts the rotating mechanism under the workpiece to make the workpiece rotate at high speed. During the rotation process, the hemming mechanism rotates slightly to perform hemming operation on the edge of the workpiece. When the hemming work is completed, the hemming wheel is released to separate the hemming mechanism from the workpiece, and then the chamfering mechanism on the other side is started to make the chamfering grinding block close to the edge of the workpiece, and the chamfering operation is performed on the edge of the workpiece after the hemming process. As the workpiece rotates, after the chamfering operation of the workpiece is completed, the chamfering grinding block is separated from the workpiece, and the rotating mechanism is stopped at this time. After the workpiece stops rotating, the clamping mechanism is released, and the workpiece is removed, and the work is completed.

[0035] Specifically, both ends of a short side surface of the movable shell 210 close to the conveyor 130 are fixed with connecting buckles 211, one end of the connecting buckle 211 is fixed to the end of the short side surface of the rotating plate 220, and the inner bottom surface of the movable shell 210 is rotatably connected to the middle of one end of the connecting buckle 211, and the top surface of the first pushing rod 240 is rotatably connected to one end of the bottom surface of the rotating plate 220.

When in use, the rotating plate 220 is rotated up and down by starting the setting of the first pushing rod 240, and the two third fixed The tops of the adjacent surfaces of the plate 310 are provided with arc-shaped sliding grooves 311, and a second rotating shaft 321 is fixed at the position of the rotating frame 320 corresponding to the arc-shaped sliding groove 311, and the outer side of the second rotating shaft 321 is slidably connected to the inner side of the arc-shaped sliding groove 311, and a third motor 330 is fixed to the outer side of a third fixed plate 310, and a mounting platform 331 is fixed to the bottom surface of the third motor 330, and the mounting platform 331 is fixedly connected to the third fixed plate 310, and a third rotating shaft 340 is fixed on both sides of the end of the rotating frame 320 close to the moving shell 210, and the third rotating shaft 340 is rotatably connected to the third fixed plate 310, and the motor shaft of the third motor 330 passes through the third fixed plate 310, and the outer side of the motor shaft of the third motor 330 is fixedly connected to the inner side of the end of a third rotating shaft 340, a movable groove is opened in the middle position of the rotating frame 320, a second push rod 350 is fixed to one end of the inner side wall of the movable groove of the rotating frame 320, a slider is fixed to one end of the second push rod 350, the top surface of the slider at the end of the second push rod 350 is rotatably connected to the first rolling wheel 360, and the top surface of one end of the rotating frame 320 close to the movable shell 210 is rotatably connected to the second rolling wheel 370, through the set arc sliding groove 311, when the rolling operation is performed, the second push rod 350 is started to make the first rolling wheel 360 close to the outer side of the edge of the workpiece. , and then start the third motor 330, so that the rotating frame 320 rotates along the trajectory of the arc-shaped sliding groove 311 with the third rotating shaft 340 as the axis, thereby driving the first hemming wheel 360 and the second hemming wheel 370 to rotate. Under the action of the first hemming wheel 360 and the second hemming wheel 370, the edge of the workpiece will be slowly rolled up to perform the hemming operation. The top surface height of the rotating frame 320 is lower than the bottom surface height of the first fixed plate 260. By setting the rotating frame 320 lower than the first fixed plate 260, when the workpiece is placed, the edge of the workpiece can smoothly enter between the first hemming wheel 360 and the second hemming wheel 370, which is convenient for the hemming operation.

[0036] Working principle: When in use, first place the workpieces on the top surface of the conveyor 130 in sequence, and transport them to the corresponding clamping mechanism 200 by the conveyor 130, and then start the first push rod 240, so that the rotating plate 220 drives the second motor 230 and the upper clamping assembly to flip along the connecting buckle 211. When the clamping assembly flips to a certain angle, start the first motor 180, so that the moving shell 210 drives the clamping mechanism 200 to move toward the conveyor 130. When the clamping assembly moves to the workpiece on the top of the conveyor 130, After the workpiece is inserted into the workpiece, the first motor 180 continues to drive the clamping assembly to move toward the inside of the workpiece, and at the same time, the electric telescopic rod 262 is started to adjust the relative position of the sliding sleeve 280 therewith. After the second fixed plate 282 contacts the inner wall of the workpiece, it moves along the electric telescopic rod 262 toward the sliding bracket 261, thereby driving the connecting rod 281 to rotate. At this time, the clamping block 270, driven by the connecting rod 281, will slide outward along the sliding groove on the sliding bracket 261, so that the clamping block 270 contacts and squeezes the inner wall of the workpiece, and clamps the workpiece from the inside.

[0037] Then, the first motor 180 is started to reverse, so that the clamping mechanism 200 moves to the original position. When the movable shell 210 moves to the initial position, the first push rod 240 is started again to shorten the first push rod 240. The rotating plate 220 rotates downward under the drive of the first push rod 240, so that the clamping assembly drives the workpiece to move downward. Since the depth of the workpiece is greater than the clamping assembly, the edge of the workpiece will exceed the bottom of the clamping device, so that the edge of the workpiece can be placed between the first hemming wheel 360 and the second hemming wheel 370.

[0038] At this time, the second motor 230 is started to make the upper clamping device and the workpiece rotate at high speed, and then the second push rod 350 is started to push the first rolling wheel 360 to move toward the movable shell 210. When the first rolling wheel 360 is close to the second rolling wheel 370, the first rolling wheel 360 and the second rolling wheel 370 clamp the edge of the workpiece. Then the third motor 330 is started to drive the third rotating shaft 340 and the rotating frame 320 to rotate, so that the second rotating shaft 321 slides inside the arc-shaped sliding groove 311, so that the first rolling wheel 360 and the second rolling wheel 370 clamp the edge of the workpiece for deflection. Because the workpiece is in a high-speed rotating state at this time, the first rolling wheel 360 and the second rolling wheel 370 can roll the edge of the workpiece.

[0039] After the workpiece hemming is completed, the second push rod 350 is started to shorten the second push rod 350, driving the first hemming wheel 360 to leave the edge of the workpiece, and then the third motor 330 is started to make the second hemming wheel 370 separate from the edge of the workpiece, and then the third push rod 430 is started to extend the third push rod 430, so that the sliding block 440 and the chamfering grinding block 450 move toward the moving shell 210, so that the chamfering grinding block 450 is close to the edge of the workpiece, and the edge of the workpiece is chamfered. After the chamfering work is completed, the third push rod 430 is started again to shorten the third push rod 430, so that the chamfering grinding block 450 separates from the edge of the workpiece.

[0040] After the chamfering is completed, the second motor 230 is turned off to stop the upper clamping device from rotating. When the workpiece stops, the first push rod 240 is started again to make the rotating plate 220 drive the second motor 230 and the upper clamping assembly to flip along the connecting buckle 211. When the clamping assembly flips to a certain angle, the first motor 180 and the electric telescopic rod 262 are started to make the movable shell 210 drive the clamping mechanism 200 to move toward the conveyor 130. When the workpiece is placed on the edge of the top surface of the conveyor 130, the electric telescopic rod 262 drives the sliding sleeve 280 to move so that the clamping block 270 is disengaged from the inner wall of the workpiece, thereby releasing the workpiece and disengaging the inner wall of the workpiece from the clamping block 270. At the same time, the second fixed plate 282 pushes the workpiece to move toward the conveyor 130. When the workpiece is pushed to a suitable position, the first motor 180 is started again to make the movable shell 210 drive the upper structure to return to its original position, so that the rotating plate 220 is flipped to its original position. At this point, the work is completed.
