[0028] First embodiment:

[0029] See also Figures 1 to 5 The present invention provides a flange transposition device, including a base 101 and a transposition component, wherein the transposition component includes a clamping unit, a flange 102, a moving unit, a motor 103, a bracket 104, a support plate 105, a plurality of first electromagnets 106, a plurality of pressing units, two second electromagnets 107, two metal blocks 108 and a limiting unit, wherein the support plate 105 has two limiting grooves 109, the clamping unit includes a first cylinder 110 and a clamping plate 111, the moving unit includes a slide rail 112, a slider 113 and a first screw machine 114, the pressing unit includes a second cylinder 115, a connecting block 116, a connecting rod 117, a rotating shaft 118, two fixing plates 119, a pressure sensor 120 and a protective pad 121, the limiting unit includes a slide rod 122, a stabilizing rod 123 and a spring 124, the slide rod 122 has a groove 125, and the slide rail 112 has a slide groove 126.

[0030] Among them, the clamping unit is arranged above the base 101, the flange 102 is arranged on the clamping unit, the moving unit is arranged above the base 101, the motor 103 is arranged on the moving unit, the bracket 104 is arranged at the output end of the motor 103, the support plate 105 is arranged below the bracket 104, and multiple first electromagnets 106 are fixedly connected to the support plate 105 and symmetrically distributed on both sides of the support plate 105. Multiple pressing units are symmetrically arranged on the support plate 105, and the support plate 105 has two limiting grooves 109. Two second electromagnets 107 are respectively arranged inside the corresponding limiting grooves 109. The limiting unit is arranged on the moving unit and the motor 103, and the two metal blocks 108 are both arranged on the limiting unit. The flange 102 is fixed by the clamping unit. After the processing is completed, the moving unit drives the support plate 105 to approach the flange 102, and then the second electromagnet 107 is energized to suck the metal block 108 into the limiting groove 109, limiting the support plate 105 so that it cannot rotate. At this time, the first electromagnet 106 contacts the flange 102 and is energized to generate magnetic force to adsorb and fix the flange 102. At the same time, the pressing unit presses and fixes the flange 102, and then the clamping unit is released to move the flange 102 out. At the same time, an unprocessed flange 102 is installed on the other side of the support plate 105. It is only necessary to start the motor 103 to drive the bracket 104 and the support plate 105 to rotate, and then place the unprocessed flange 102 in the clamping unit and re-fix it. When the flange 102 is installed and processed, the moving unit can drive the support plate 105 to move, so that the processed flange 102 is transported to the placement position. After it is removed, a new unprocessed flange 102 is re-installed on the support plate 105, and the above operation is repeated.

[0031] Secondly, the first cylinder 110 is disposed above the base 101, the output end of the first cylinder 110 is fixedly connected to the clamping plate 111, and the flange 102 is disposed between the two clamping plates 111. When the first cylinder 110 is started, the clamping plate 111 is driven to move, clamping and fixing the flange 102, thereby facilitating drilling and grinding and deburring operations.

[0032] Meanwhile, the slide rail 112 is disposed above the base 101, the slider 113 is slidably connected to the slide rail 112, the first screw machine 114 is disposed on the slide rail 112, the slider 113 is disposed at the output end of the first screw machine 114, and the motor 103 is fixedly connected to the slider 113 and is located below the slider 113. When the first screw machine 114 is started, the slider 113 is driven to slide in the slide rail 112, thereby driving the support plate 105 to move.

[0033] In addition, the second cylinder 115 is rotatably connected to one end of the support plate 105, the output end of the second cylinder 115 is fixedly connected to one end of the connecting block 116, one end of the connecting rod 117 is rotatably connected to one side of the connecting block 116, the two fixed plates 119 are both fixedly connected to the support plate 105, the two ends of the rotating shaft 118 are respectively fixedly connected to the corresponding fixed plates 119, the connecting rod 117 is sleeved on the outside of the rotating shaft 118, the connecting rod 117 is rotatably connected to the rotating shaft 118, the pressure sensor 120 is fixedly connected to the other end of the connecting rod 117, and the protective pad 121 is arranged on the pressure sensor 120. The second cylinder 115 is started, driving the connecting block 116 to move, driving the connecting rod 117 to rotate on the rotating shaft 118, so that the connecting rod 117 presses and fixes the flange 102. At the same time, the pressure sensor 120 can monitor the pressure value of the pressing to avoid looseness due to the pressing. The protective pad 121 can prevent the flange 102 from being scratched and worn.

[0034] Finally, the slide rod 122 has a groove 125, the slide rail 112 has a slide groove 126, one end of the slide rod 122 is slidably connected to the slide groove 126, the other end of the slide rod 122 is located on one side of the limiting groove 109, the two ends of the stabilizing rod 123 are respectively fixedly connected to the slide rod 122 and the motor 103, the two ends of the spring 124 are respectively movably connected to the inner side wall of the groove 125 and one end of the metal block 108, and the other end of the metal block 108 is located inside the limiting groove 109. When the support plate 105 moves, the slide bar 122 slides in the slide groove 126, and the stabilizing rod 123 is connected to the motor 103 to provide stability to the slide bar 122. When the support plate 105 moves to the slide bar 122, the second electromagnet 107 is energized to suck the metal block 108 out of the groove 125 and into the limiting groove 109, thereby limiting the support plate 105 and preventing it from rotating, thereby ensuring the stability of the docking with the flange 102 on the clamping unit. When the support plate 105 needs to rotate, the second electromagnet 107 is de-energized, and the spring 124 contracts at this time, driving the metal block 108 to disengage from the limiting groove 109.

[0035] When using a flange replacement device of this embodiment, the first cylinder 110 is started to drive the clamping plate 111 to move, clamp and fix the flange 102, so as to facilitate drilling and grinding and deburring operations. After the processing is completed, the first screw machine 114 is started to drive the slider 113 to slide in the slide rail 112, drive the support plate 105 to move close to the flange 102, and at the same time the motor 103 is started to drive the support plate 105 to rotate and adjust the position so that the first electromagnet 106 is facing the flange 102. At this time, the second electromagnet 107 is energized to suck the metal block 108 into the limiting groove 109, limiting the support plate 105 so that it cannot rotate. At this time, the first electromagnet 106 contacts the flange 102 and is energized to generate magnetic force to absorb and fix the flange 102. Then the second cylinder 115 is started to drive the connecting block 116 to move and drive the connecting rod 117 to rotate on the rotating shaft 118, so that the connecting rod 117 presses and fixes the flange 102. At the same time, the pressure sensor 120 can monitor the pressure value of the pressing to avoid loosening during pressing. The protective pad 12 1 can avoid scratching and wearing the flange 102, and then the clamping unit is loosened to remove the flange 102. At this time, an unprocessed flange 102 is still installed on the other side of the support plate 105. The second electromagnet 107 is powered off, and the spring 124 contracts to drive the metal block 108 to break away from the limiting groove 109, canceling the limit of the support plate 105, and then the motor 103 is started to drive the bracket 104 and the support plate 105 to rotate, and the unprocessed flange 102 is placed in the clamping unit and fixed. After the flange 102 is installed, the moving unit can drive the support plate 105 away, so that the processed flange 102 is transported to the placement position, removed, and a new unprocessed flange 102 is reinstalled on the support plate 105, and the above operations are repeated. Through the above structural setting, the new flange 102 can be quickly installed after unloading, which greatly reduces the replacement time and improves the speed of reloading after the flange 102 is removed, avoiding the influence of long waiting time on efficiency. At the same time, only one device is needed, and there is no need to set up two devices for loading and unloading for cooperation, and the operation is simple and fast.
