DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] Embodiment

[0037] The present utility model will be further described below in conjunction with the accompanying drawings.

[0038] As Figure 1 shown, a dressing device for the abrasive surface of an abrasive coated abrasive provided in this embodiment includes:

[0039] A dressing frame 1 and a dressing rod 2. The dressing frame 1 is connected to the machine table 3 and the horizontal position of the dressing frame 1 relative to the machine table 3 is adjustable. The dressing rod 2 is installed on the dressing frame 1. A guide roller 4 is installed on the machine table 3, and an abrasive coated abrasive 5 is wound around the guide roller 4. The dressing rod 2 is located on the side of the abrasive coated abrasive 5 and contacts the abrasive surface of the abrasive coated abrasive 5.

[0040] The working principle and beneficial effects of the present utility model are as follows:

[0041] A dressing device for the abrasive surface of an abrasive coated abrasive provided in this embodiment. The dressing frame 1 is installed on the machine table 3 of the abrasive coated abrasive flexing machine. The dressing rod 2 is fixed by the dressing frame 1, and the dressing rod 2 is arranged on one side of the guide roller 4. When the abrasive coated abrasive 5 travels on the guide roller 4, the dressing rod 2 contacts the protruding particles on the abrasive surface of the abrasive coated abrasive 5. The dressing rod 2 squeezes and breaks the sharp corners of the abrasive particles protruding from the abrasive surface. After breaking, the abrasive particle debris falls with the movement of the abrasive coated abrasive 5 under the action of gravity and will not adhere to the surface of the abrasive coated abrasive 5 too much.

[0042] Through the above structural design, a dressing device for the abrasive surface of an abrasive coated abrasive is installed on the abrasive coated abrasive flexing machine to dress the protruding particles on the abrasive surface, achieving the effect of equal height distribution of the abrasive particles on the abrasive surface, overcoming the problem that linear groove defects are likely to appear on the workpiece during the grinding process, significantly improving the surface processing quality of the workpiece, with a simple structure, obvious effect, and strong practicability. At the same time, the attachment of particulate matter on the surface of the abrasive coated abrasive 5 during the dressing process is reduced, thereby reducing the wear of the dressing rod 2, extending the service life, and reducing the risk of deformation of the abrasive coated abrasive 5 caused by the accumulation of attachments.

[0043] As Figures 1 to 3 shown, in one embodiment, the dressing frame 1 includes:

[0044] Support plates 11. Two support plates 11 are symmetrically connected to both sides of the machine table 3;

[0045] Dressing frame slide rail 12, the dressing frame slide rail 12 is connected to the top end of the support plate 11, and the dressing frame slide rail 12 extends in the horizontal direction and is arranged perpendicular to the guide roller 4;

[0046] Slider 13, the slider 13 is slidably connected to the top end of the dressing frame slide rail 12;

[0047] Cross bar 14, the cross bar 14 is connected between the two sliders 13;

[0048] Mounting rings 15, two mounting rings 15 are symmetrically connected to the cross bar 14, and both ends of the dressing rod 2 are respectively connected to the two mounting rings 15.

[0049] The working principle and beneficial effects of the above technical solution are as follows:

[0050] The dressing frame 1 is used to fix the dressing rod 2. The two support plates 11 of the dressing frame 1 are respectively welded to both sides of the machine table 3. The dressing frame slide rail 12 is welded on the support plate 12, the cross bar 14 is welded on the dressing frame slide rail 12, and the mounting rings 15 are welded on both sides of the cross bar 14. The dressing rod 2 is installed in the two mounting rings 15. The length of the dressing rod 2 is greater than the length of the guide roller 4, so that the dressing rod 2 can contact the coated abrasive 5 on the entire guide roller 4; Push the slider 13 to slide on the dressing frame slide rail 12, adjust the distance between the dressing rod 2 and the coated abrasive 5 to a preset value, and dress the particles protruding from this preset value on the sand surface, so that the abrasive particles on the sand surface are evenly distributed in height.

[0051] As Figure 4 shown, in one embodiment, a first locking bolt 16 is provided through the top end of the mounting ring 15, and the first locking bolt 16 presses against the top end of the dressing rod 2. Rotate the first locking bolt 16 at the top end of the mounting ring 15, and the end of the first locking bolt 16 presses against the dressing rod 2 to limit and fix it.

[0052] In one embodiment, the inner diameter of the mounting ring 15 is larger than the diameter of the dressing rod 2. So that the mounting ring 15 can use dressing rods 2 of different sizes and is convenient for the installation of the dressing rod 2.

[0053] As Figure 5 shown, in one embodiment, a locking hole 17 is provided on the side surface of the end of the dressing rod 2, and the bottom end of the first locking bolt 16 is connected to the locking hole 17. With the setting of the locking hole 17, the bottom end of the first locking bolt 16 can be clamped in the locking hole 17 to limit the dressing rod 2 in the left and right directions and prevent the dressing rod 2 from being displaced due to force during the dressing process.

[0054] In one embodiment, a plurality of locking holes 17 are provided, and the plurality of locking holes 17 are evenly arranged along the circumferential direction of the dressing rod 2. By providing a plurality of locking holes 17, when the dressing rod 2 is used for a period of time, rotate the dressing rod 2 so that different positions of it contact the coated abrasive 5, improve the utilization rate of the dressing rod 2, and reduce the local wear of the dressing rod 2.

[0055] As Figure 6 shown, in one embodiment, the dressing frame 1 further includes:

[0056] Side guide plates 18, which are connected to the support plate 11 and are located on one side of the dressing frame slide rail 12. A side guide groove 19 is horizontally arranged on the side guide plates 18;

[0058] The working principle and beneficial effects of the above technical solution are as follows:

[0059] When the slide seat 13 slides on the dressing frame slide rail 12, the slide seat 13 drives the guide bolts 20 to move synchronously, and the guide bolts 20 slide in the side guide groove 19 to guide the slide seat 13.

[0060] In one embodiment, a second locking bolt 21 is connected through the top end of the slide seat 13, and the second locking bolt 21 passes through the slide seat 13 and presses against the top end of the dressing frame slide rail 12. After the slide seat 13 moves to a preset position, rotate the second locking bolt 21 so that its bottom end presses against the dressing frame slide rail 12 to limit and fix the slide seat 13.

[0061] As Figure 6 shown, in one embodiment, a screw rod 22 is rotatably connected to one end of the inner wall of the slide seat 13 away from the guide roller 4. A threaded hole is arranged at the end of the dressing frame slide rail 12, and the screw rod 22 is connected in the threaded hole.

[0062] The end of the screw rod 22 extends out of the slide seat 13 and is connected to a turntable 23. An adjusting handle 24 is connected to the turntable 23, and scale lines are arranged on the turntable 23.

[0063] The working principle and beneficial effects of the above technical solution are as follows:

[0064] When adjusting the position of the slide seat 13, rotate the adjusting handle 24 at its end. The adjusting handle 24 drives the turntable 23 to rotate, and the screw rod 22 at the center of the turntable 23 rotates accordingly. The screw rod 22 is in threaded transmission with the threaded hole, thereby driving the slide seat 13 to slide on the dressing frame slide rail 12. The adjustment process is simple and labor-saving; the scale lines arranged on the turntable 23 can display the adjustment distance of the slide seat 13. Through the above structural design, by adopting threaded transmission and the turntable 23 with scale lines, the adjustment accuracy of the slide seat 13 is improved, which is convenient for the precise positioning of the dressing rod 2, and further improves the dressing quality of the coated abrasive 5.
