The cylindrical workpiece outer wall automatic grinding device of this structural form has a simple structure, ingenious design and reasonable layout. It designs an automatic structure to solve various problems existing in the traditional manual grinding method. It uses two rollers (active roller and passive roller) to support the cylindrical workpiece to be ground. At the same time, due to the special design of these two rollers, the cylindrical workpiece can rotate while moving radially, so that the two grinding mechanisms arranged above the workpiece can automatically grind the outer wall of the workpiece, thereby realizing automatic grinding.

DETAILED DESCRIPTION

The specific implementation of the utility model will be described below in conjunction with the accompanying drawings. As shown in Figures 1 and 2: An automatic grinding device for the outer wall of a cylindrical workpiece includes a working platform 1 supported by a frame, on which an active roller 2 and a passive roller 3 are rotatably supported, one end of the active roller 2 is connected to the working end of an active roller motor 4 located below the working platform 1 through a sprocket chain transmission pair, the axis of the active roller 2 is horizontally distributed, and the axis of the passive roller 3 forms an angle of 5-10° with the horizontal plane,

The working platform 1 is provided with a first grinding mechanism 5 and a second grinding mechanism 6 having the same structure.

The first grinding mechanism 5 includes a first base 8 slidably connected to the X-axis guide rail 7, a nut block is arranged in the first base 8, the nut block is threadedly connected to the first screw rod 9 rotatably supported on the working platform 1, a hand wheel 10 is arranged at the end of the first screw rod 9, a first support frame 11 is arranged on the first base 8, an inclined guide rail 12 is arranged on the side wall of the first support frame 11, a second base 13 is slidably connected to the inclined guide rail 12, a nut block is arranged in the second base 13, the nut block is threadedly connected to the second screw rod 14 rotatably supported on the first support frame 11, a hand wheel 10 is arranged at the top end of the second screw rod 14, the inclined guide rail 12 forms an angle of 5-10° with the plumb line,

The active roller 2 is distributed along the Y-axis direction.

A second support frame 15 is provided on the second base 13, and a grinding motor 16 is supported on the second support frame 15. The output end of the grinding motor 16 is connected to a grinding shaft 18 rotatably supported at the bottom of the second support frame 15 through a pulley transmission pair 17, and a grinding cloth wheel 19 is provided at one end of the grinding shaft 18.

The working process of the cylindrical workpiece outer wall automatic grinding device of the embodiment of the utility model is as follows: first, the workpiece 20 to be subjected to outer wall grinding treatment is placed between the active roller 2 and the passive roller 3, and the two rollers jointly support the workpiece 20 upward from the oblique bottom, and then the first grinding mechanism 5 and the second grinding mechanism 6 are adjusted to make the grinding cloth wheel 19 on the first grinding mechanism 5 contact with the outer wall of the workpiece 20, and at the same time, the grinding cloth wheel 19 on the second grinding mechanism 6 is also adjusted to a position where the workpiece 20 can contact with its outer wall after moving over (the adjustment position of the second grinding mechanism 6 can be determined according to the adjustment position of the first grinding mechanism 5), and the preparation work is completed;

Then start the device, the active roller motor 4 works to drive the active roller 2 to rotate through the sprocket chain transmission pair, and the active roller 2 will drive the workpiece 20 to rotate when it rotates. At the same time, since the passive roller 3 is tilted (one end is high and the other end is low), the workpiece 20 will gradually move from a relatively high end to a relatively low end (along its own axial direction) during the rotation process, thereby realizing automatic feeding action;

After passing through the first grinding mechanism 5 , the workpiece 20 will enter the area where the second grinding mechanism 6 is located and continue to be ground by the second grinding mechanism 6 . The operator only needs to remove the workpiece 20 that has been ground twice in the discharge direction of the device.

When adjusting the first grinding mechanism 5 and the second grinding mechanism 6, the hand wheel 10 at the end of the first screw 8 can be rotated to drive the first screw 9 to rotate, and the first screw 9 will drive the first base 8 to move along the X-axis guide rail 7 in the X-axis direction; then the hand wheel 10 at the end of the second screw 14 can be rotated to drive the second screw 14 to rotate, and the second screw 14 will drive the second base 13 to move in the longitudinal direction along the inclined guide rail 12; through the above adjustment, it is ensured that the grinding cloth wheel 19 on the first grinding mechanism 5 can contact the outer wall of the workpiece 20; since the structures of the first grinding mechanism 5 and the second grinding mechanism 6 are exactly the same, when adjusting the second grinding mechanism 6, the second grinding mechanism 6 can be adjusted according to the adjustment parameters of the first grinding mechanism 5 (such as the number of rotations of the first screw 8, the number of rotations of the second screw 14, etc.), so as to ensure that when the workpiece 20 moves to the secondary grinding station, the grinding cloth wheel 19 in the second grinding mechanism 6 can contact its outer wall.
