The sensing mechanism is used to keep the grinding mechanism 400 at rest with the torsion spring 460 in an initial state when it is in inner cylinders of different inner diameters. The driving mechanism is used to horizontally move the fixed drum 410.
In this embodiment, a plurality of first hinge points 441 are disposed on the peripheral wall of the adjusting cylinder 440, and a plurality of second reserved openings 421 are uniformly distributed on the first collar 420 in the circumferential direction. The sensing mechanism includes a second collar 430 and a sensing assembly 470.

The sensing assembly 470 includes a telescoping rod 474, a second push rod 472, a ball 471, a second diagonal rod 475, and a third diagonal rod 476. One end of the telescopic rod 474 is arranged in the second reserved opening 421, and the other end of the telescopic rod 474 is arranged in the third reserved opening 431. The second jack 472 is slidably disposed in the second through hole 432, one end of the second jack 472 is connected to one end of the telescopic rod 474, and the ball 471 is disposed at the other end of the second jack 472.

One end of the third diagonal member 476 is rotatably coupled to the first hinge point 441 and the other end of the second diagonal member 475 is rotatably coupled to the other end of the telescoping member 474. When the radius of the cylinder barrel 200 to be ground is smaller, the balls 471 are pressed to move toward the axial center of the adjustment barrel 440, the telescopic rod 474 is stretched, the angle between the second diagonal rod 475 and the third diagonal rod 476 is increased, the second diagonal rod 475 pushes the second collar 430 to move rightward, and the third diagonal rod 476 pushes the first collar 420 to move leftward. Because the second diagonal stem 475 and the third diagonal stem 476 are equal in length, the first collar 420 and the second collar 430 are always symmetrical in distance about the first hinge point 441.

The built-in motor 120 is started, the pushing post 300 rotates, and the opening and closing member 490 is matched with the spiral groove 320 to drive the grinding mechanism 400 to move leftwards.
In the present embodiment, the spiral groove 320 is a continuous spiral groove, and the groove depth of the spiral groove 320 is deeper than the groove depth of the coplanar groove 310. When the opening and closing member 490 is pressed by the linkage ring 450 and inserted into the spiral groove 320, the opening and closing member 490 moves to the junction of the spiral groove 320 and the coplanar groove 310 and then enters the coplanar groove 310, and the grinding mechanism 400 does not move leftwards any more.
In the present embodiment, the pitch of the gradual helical groove 443 gradually increases from left to right. When the thickness to be cut is fixed, the larger the radius of the cylindrical drum 200 to be ground, the smaller the rate of increase of the torque force due to the gradual increase of the pitch of the gradual helical groove 443 from left to right, the smaller the rate of increase of the pressing force against the grinding stone 481.
In this embodiment, the width of the grinding stone 481 is the same as the distance between adjacent coplanar grooves 310. When the grinding position of the grinding stone 481 is finished to go to the next position, the width of the advancing grinding stone 481 is ensured, and the grinding efficiency is accelerated.
In this embodiment, a sliding rail 130 is disposed on the base 100, and a connecting rod is fixedly connected to the other end of the fixed drum 410 and slidably disposed in the sliding rail 130.
In this embodiment, an inner cylinder grinding apparatus further includes a third tension spring 491, a protruding ring 492 is provided on the circumferential wall of the opening and closing member 490, one end of the third tension spring 491 is fixedly connected to the protruding ring 492, and the other end of the third tension spring 491 is fixedly connected to the fixed cylinder 410. When the actuating ring 450 no longer presses the shutter 490, the shutter 490 springs back to a set height under the action of the third tension spring 491.
In this embodiment, a second tension spring 473 is sleeved on the second ejector rod 472, the second tension spring 473 is installed in the second through hole 432, a first tension spring 483 is sleeved on the first ejector rod 482, and the first tension spring 483 is installed in the first through hole 422. The cylindrical drum 200 to be ground with different radiuses is adapted so that the grinding stone 481 and the balls 471 always abut against the inner wall of the cylindrical drum 200 to be ground.
In this embodiment, the adjustment cylinder 440 is provided with a first mounting hole 442, the coupling ring 450 is provided with a second mounting hole 454, and the torsion spring head 461 is inserted into the first mounting hole 442 and the torsion spring tail 462 is inserted into the second mounting hole 454. When the linkage ring 450 moves rightward, the torsion spring 460 is driven to rotate, so that the torsion spring 460 generates torsion force.
The working process comprises the following steps: when the right end of the cylindrical drum 200 to be ground is ground, in the initial state, the grinding mechanism 400 is entirely at the ground place, and the balls 471 and the grinding stones 481 press against the ground inner wall to sense the corresponding inner diameter. At this time, the linkage ring 450 presses the opening and closing member 490, and the other end of the opening and closing member 490 is inserted into the spiral groove 320, and the torsion spring 460 is not twisted, and has no torsion force. The cylinder 200 to be ground rotates about its own axis by the external force.
The built-in motor 120 is started, the pushing post 300 rotates, and the opening and closing member 490 is matched with the spiral groove 320 to drive the grinding mechanism 400 to move leftwards. When the grinding stone 481 is propped against the grinding inner wall, the grinding stone 481 is compressed towards the axis of the adjusting cylinder 440, so that the linkage ring 450 is pushed to move rightwards relative to the adjusting cylinder 440, the linkage ring 450 does not press the opening and closing member 490 any more, the opening and closing member 490 is rebounded to set the height under the action of the third tension spring 491, and the opening and closing member 490 is still positioned in the spiral groove 320 at the moment. Under the action of the spiral groove 320, the grinding mechanism 400 continues to move leftwards until the opening and closing member 490 reaches the junction of the coplanar groove 310 and the spiral groove 320, and the pushing post 300 rotates to enable the opening and closing member 490 to come into the coplanar groove 310 because the opening and closing member 490 is not stressed at this time, the grinding mechanism 400 does not move leftwards any more, so that the grinding stone 481 grinds the inner wall of the cylindrical drum 200 to be ground at this point.
During the gradual left movement of the grinding mechanism 400, the linkage ring 450 moves rightward relative to the adjustment cylinder 440, and the adapter post 455 slides within the gradual helical groove 443, causing the second linkage ring 453 to rotate, thereby twisting the torsion spring 460, causing the torsion spring 460 to generate a torsion force. At this time, the radius of the cylindrical drum 200 to be ground is fixed, the thicker the ground portion is, the larger the difference between the radius of the grinding stone 481 and the radius of the balls 471 is, the larger the distance the link ring 450 moves right, the larger the torsion force of the torsion spring 460 is, the larger the force of the torsion spring 460 reacting against the second link ring 453 is,
the torsion of the torsion spring 460 causes the second link ring 453 to rotate and the adapter post 455 to move along the graduated helical groove 443 and thus exert a greater force on the link ring 450, so that the pressing force on the grinding stone 481 is also greater. When the thickness to be cut is fixed, the larger the radius of the cylindrical drum 200 to be ground, the smaller the rate of increase of the torque force due to the gradual increase of the pitch of the gradual helical groove 443 from left to right, the smaller the rate of increase of the pressing force against the grinding stone 481.
When the opening and closing member 490 is positioned in the same-plane groove 310, the grinding stone 481 grinds the ground part until the grinding stone 481 grinds, so that when the radius of the grinding stone 481 is consistent with that of the ball 471, the torsion spring 460 returns to the initial position to drive the linkage ring 450 to reset, and then the opening and closing member 490 is extruded, so that the opening and closing member 490 enters the spiral groove 320, and the grinding mechanism 400 continues to move leftwards.
When the radius of the cylinder barrel 200 to be ground is smaller, the balls 471 are pressed to move toward the axial center of the adjustment barrel 440, the telescopic rod 474 is stretched, the angle between the second diagonal rod 475 and the third diagonal rod 476 is increased, the second diagonal rod 475 pushes the second collar 430 to move rightward, and the third diagonal rod 476 pushes the first collar 420 to move leftward. Because the second diagonal stem 475 and the third diagonal stem 476 are equal in length, the first collar 420 and the second collar 430 are always symmetrical in distance about the first hinge point 441. When the grinding stone 481 is pressed and moved to the axis of the adjusting cylinder 440, the hinge point of the first inclined rod 484 and the second hinge point 452 is always co-rounded with the first hinge point 441, so that the torsion spring 460 is not twisted in the initial state.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
