Technical Field

[0002] Roll grinding is a common surface treatment method, which is usually used to remove the rough parts of the material surface to make it smoother. This method uses a rotating abrasive wheel or sandpaper to achieve the grinding effect through contact and friction with the surface of the workpiece.

[0003] When the existing expansion and contraction reel is subjected to rolling grinding, the expansion and contraction reel body is usually fixed by a clamp, and then its surface is ground by a rotating abrasive wheel. However, in actual use, after the fixed expansion and contraction reel is ground on one side, it may be necessary to adjust the clamping position several times to ensure that the ground surface is treated evenly and comprehensively. This situation will affect the grinding efficiency of the expansion and contraction reel. For this reason, we propose a rolling grinding assembly for the expansion and contraction reel.

[0021] When performing rolling grinding of the expansion and contraction reel, first place the expansion and contraction reel to be grinded between the two rotating clamps 5, and use two displacement components to drive the first movable plate 3 and the second movable plate 4 to approach each other, so that the two rotating clamps 5 clamp and fix the expansion and contraction reel, then use the electric cylinder 13 to drive the grinder 16 to move to the top of the expansion and contraction reel, and use the grinding wheel 17 to grind the outer side of the expansion and contraction reel. During the grinding process, the expansion and contraction reel is driven to rotate under the action of the two rotating clamps 5 by the rolling component, and at the same time, the expansion and contraction reel is driven to move left and right above the bottom plate 1 in cooperation with the two displacement components, thereby further expanding the grinding surface of the expansion and contraction reel, further accelerating the grinding speed, and achieving uniform and comprehensive grinding of the expansion and contraction reel.

[0022] like Figure 1-Figure 4As shown, the rolling assembly includes a connecting block 6, which is fixedly connected to one side of the first movable plate 3, and the bottom of the connecting block 6 is rotatably connected to a worm 9, and one side of the first movable plate 3 is rotatably connected to a worm wheel 8, the outer side of the worm wheel 8 is meshed with the outer side of the worm 9, one end of the worm wheel 8 passes through the first movable plate 3 and is fixedly connected to the rotating clamping plate 5, and a power motor 7 is fixedly installed on the top of the connecting block 6, and the output end of the power motor 7 passes through the connecting block 6 and is fixedly connected to the worm 9.

[0023] The worm 9 is driven by the power motor 7 to rotate at the bottom of the connecting block 6. Since the outer side of the worm wheel 8 is meshed with the outer side of the worm 9, the worm 9 rotates and the worm wheel 8 is driven to rotate synchronously, and the expansion and contraction reel is further rotated under the action of the two rotating clamps 5, thereby facilitating the expansion and contraction reel The grinding area is expanded and the grinding efficiency is further improved.

[0024] like Figure 1-Figure 4 As shown, the displacement assembly includes two slide grooves 10, and the two slide grooves 10 are both opened at the top of the base plate 1.

During the grinding process, the power motor 7 drives the worm 9 to rotate at the bottom of the connecting block 6. Since the outer side of the worm wheel 8 is meshed with the outer side of the worm 9, the worm 9 rotates and drives the worm wheel 8 to rotate synchronously, further causing the expansion and contraction reel to rotate under the action of the two rotating clamping plates 5.
