When the equipment is required to work, a worker grasps the pressing frame 3, and presses the controller button 7f, the controller button 7f is an elastic button, when the controller button 7f is pressed for the first time, the controller button 7f transmits a signal to the controller 7e, the controller 7e drives the motor 7d to rotate for a preset number of turns, the first driving shaft 7a drives the threaded column 1e and the first gear 5a to rotate, so that a part needing to be cut is cut off, the worker presses the controller button 7f again, the controller button 7f transmits a signal to the driving motor 7d, the driving motor 7d rotates reversely, the first driving shaft 7a rotates reversely, the threaded column 1e and the first gear 5a rotate reversely, and the cut metal ring automatically drops.
The working principle is as follows: when a metal ring on the automobile oil tank 6 needs to be cut off, firstly, a worker grasps the cover cap 3e, sleeves the anti-skid pad ring 3a on the outer edge of the metal ring, tightly presses the anti-skid pad ring 3a on the automobile oil tank 6, and in the process, the expansion clamping mechanism 1 is inserted into the metal ring;
then, a worker presses the controller button 7f, the controller button 7f is an elastic button, when the controller button 7f is pressed for the first time, the controller button 7f transmits a signal to the controller 7e, the controller 7e drives the motor 7d to rotate for a preset number of turns, and the first driving shaft 7a drives the threaded column 1e and the first gear 5a to rotate so as to cut off a part needing to be cut;
when the first driving shaft 7a drives the threaded column 1e to rotate, the threaded column 1e is meshed with a threaded hole in the mounting top plate 1c, the mounting top plate 1c moves upwards along the axial direction of the threaded column 1e, the two expansion arms 1a are abutted to the outer edge of the conical column 1d, the two expansion arms 1a move outwards, and the two expansion arms 1a clamp the metal ring;
and in the process that the installation top plate 1c rises, the installation top plate 1c drives two first guide posts 1b to move simultaneously, when the first guide posts 1b move upwards, the rotary seat 2a moves upwards, so that the rotary seat 2a pushes the push rod 2b upwards, so that the push rod 2b rotates and slides along the support post 2c, the end part of the push rod 2b presses the interference circular plate 2h downwards, so that the lower push post 2e moves downwards, so that the lower push post 2e drives the rotary cutting mechanism 4 to move downwards, and in the process that the interference circular plate 2h presses downwards, the interference circular plate 2h compresses the second interference spring 2f, and by the way of prying motion energy transmission, the descending distance of the lower push post 2e is short relative to the ascending distance of the expansion arm 1a, so as to ensure that at the very beginning, the distance between the two expansion arms 1a and the metal ring is large, the expansion clamping mechanism 1 is convenient to insert into the metal ring;
when the lower pushing column 2e descends, the lower pushing column 2e drives the clamping ring 4d to descend, so that the clamping ring 4d drives the circular mounting plate 4a to descend through the two connecting arc plates 4e, the circular mounting plate 4a drives the cutter 4b to descend through the extension frame 4c, and the cutter 4b cuts the automobile oil tank 6;
when the circular mounting plate 4a descends, the first gear 5a rotates to drive the second gear 5b to rotate, the second gear 5b drives the gear ring 5c to move, the gear ring 5c drives the circular mounting plate 4a to rotate, and in the descending process of the rotary cutting mechanism 4, the gear ring 5c also descends, the thickness of the gear ring 5c is larger than that of the second gear 5b, therefore, the gear ring 5c is meshed with the second gear 5b, the gear ring 5c drives the cutter 4b to rotate through the circular mounting plate 4a and the extension frame 4c, the cutter 4b is enabled to annularly cut the top of the automobile oil tank 6, and the cutter 4b is enabled to rotate and descend through the combination of the rotation of the cutter 4b, so that the cutter 4b can cut a part to be cut;
so that the rotary cutting mechanism 4 performs annular cutting on the automobile oil tank 6, when the cutting is not completed, the expansion clamping mechanism 1 clamps the metal ring, but the two expanding and clamping mechanisms 1 still move for a certain distance due to the action of the rubber pads 1a1, the rubber pads 1a1 are soft rubber pads, the thickness of the rubber pads 1a1 is set according to the actual cutting requirement, and during the compression of the rubber pad section 1a1, the rubber pad 1a1 will also pull the metal ring upwards, the part to be cut is pulled upwards, the thin wall at the last point which is cut is collided with the cutter of the rotary cutting mechanism 4, so that the cutter can cut off the part to be cut more quickly, the cutting time is reduced, due to the clamping action of the two expansion arms 1a, the cut metal ring cannot fall into the automobile oil tank 6;
the controller button 7f is pressed again by a worker, the controller button 7f transmits a signal to the driving motor 7d, the driving motor 7d rotates reversely, the first driving shaft 7a rotates reversely, the threaded column 1e and the first gear 5a rotate reversely, the cut metal ring automatically drops, the complete use action of the equipment is further completed, and the process is repeated when the metal ring on the next automobile oil tank 6 is cut.
Example two:
this embodiment is substantially the same as the first embodiment, and is characterized in that:
in this embodiment, referring to fig. 13 and 14, the driving mechanism includes a second driving shaft 8a, a third limiting ring 8b and a handle 8c, one end of the second driving shaft 8a is fixedly connected to the threaded column 1e through a coupler, the other end of the second driving shaft 8a is fixedly connected to the handle 8c, two third limiting rings 8b are fixedly mounted on the second driving shaft 8a, inner sides of the two third limiting rings 8b are attached to two sides of the connecting plate 3d, and the first gear 5a is fixedly mounted on the second driving shaft 8 a. When needs equipment carries out the during operation, rotate handle 8c through the workman for handle 8c drives second drive shaft 8a and rotates, makes second drive shaft 8a drive screw post 1e and first gear 5a rotate, makes the position that will cut down, when the position that needs will cut moves down, through reverse rotation handle 8c, makes screw post 1e and first gear 5a reversal rotation, makes the becket that cuts automatically drop.
