Description

Technical Field

[0001] This utility model relates to the technical field of grinding wheel dressing tools, specifically a manual dressing device for a fine grinding machine grinding wheel. Background Technology

[0002] During the grinding process, the abrasive grains of the grinding wheel in a precision grinding mill gradually wear down and become dull, leading to a decrease in cutting efficiency. In order to restore the sharpness of the grinding wheel, it is necessary to remove the surface passivation layer.

[0003] In existing technologies, when dressing grinding wheels, the following methods are typically used: Figure 4 The handheld grinding wheel dresser shown is used for manual dressing of grinding wheels. The handheld grinding wheel dresser mainly includes a handheld bar, a connecting block, and a dressing head. The handheld bar, connecting block, and dressing head adopt an integrated connection structure. During operation, the operator holds the handheld bar and brings the dressing head close to and in contact with the grinding wheel to dress it.

[0004] In the process of implementing the above, the inventors discovered at least the following problems with the technology: existing handheld grinding wheel dressers are all one-piece structures, requiring replacement of the entire device after the dressing head is damaged, resulting in high operating costs. Therefore, we propose a manual dressing device for fine grinding wheels. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a manual dressing device for a fine grinding mill wheel, which has the following advantages:

[0019] 1. This utility model, by setting an installation block and an installation groove, allows for the initial installation of the dressing head when using the device. The installation block of the dressing head is inserted into the installation groove, allowing the dovetail block to slide along the dovetail groove, thus limiting the front and rear movement of the dressing head. Then, the drive component rotates the screw, causing the screw to drive the movable block to slide along the guide rod. The movable block then drives the locking block to insert into the locking groove of the installation block, locking the installation block into the installation groove. This completes the installation of the dressing head, enabling the device to dress the grinding wheel. If the dressing head is damaged, simply reverse the rotation of the screw using the drive component to remove the locking block from the locking groove, allowing the dressing head to be removed and replaced separately, reducing operating costs.

[0020] 2. By setting grooves and cover plates, this utility model can protect the nuts and prevent powder generated during the trimming process from contaminating the nuts. Attached Figure Description

[0030] This utility model provides a technical solution:

[0031] Please see Figures 1-3 A manual dressing device for a fine grinding wheel includes a hand-held rod 1, a connecting block 2, and a dressing head 3. The surface of the hand-held rod 1 is provided with anti-slip texture 11 to prevent the operator from slipping when holding the rod. The dressing head 3 is made of diamond to ensure its hardness and rigidity, thus extending its service life.

[0032] Reference Figures 1-3The connecting block 2 is fixedly connected to one end of the handheld rod 1. The trimming head 3 is detachably installed on the connecting block 2. A mounting block 31 is fixedly connected to one side of the trimming head 3. Two locking grooves 32 are provided on one side of the mounting block 31. A mounting groove 21 that matches the mounting block 31 is provided on one side of the connecting block 2. A cavity is provided inside the connecting block 2. A screw 22 is rotatably installed in the cavity. A movable block 23 is threadedly connected to the screw 22. Locking blocks 24 are fixedly connected to both ends of the movable block 23. One end of the locking block 24 passes through the mounting groove 21. A driving component 25 for driving the screw 22 to rotate is provided on the connecting block 2. Dovetail grooves 33 are provided on both sides of the mounting block 31. Dovetail blocks 26 that slide with the dovetail grooves 33 are provided on both sides of the mounting grooves 21. A guide rod 2 arranged parallel to the screw 22 is fixedly installed inside the cavity. 9. The movable block 23 is slidably sleeved on the guide rod 29. By setting the mounting block 31 and the mounting groove 21, when using the device, the dressing head 3 can be installed first. The mounting block 31 of the dressing head 3 is inserted into the mounting groove 21, and the dovetail block 26 slides along the dovetail groove 33 to limit the front and rear movement of the dressing head 3. Then, the drive member 25 rotates the screw 22, causing the screw 22 to drive the movable block 23 to slide along the guide rod 29, so that the movable block 23 drives the locking block 24 to insert into the locking groove 32 of the mounting block 31, locking the mounting block 31 into the mounting groove 21. The installation of the dressing head 3 is completed, so that the device can be used to dress the grinding wheel. After the dressing head 3 is damaged, the drive member 25 only needs to rotate the screw 22 in the opposite direction to remove the locking block 24 from the locking groove 32, so that the dressing head 3 can be removed and replaced separately, reducing the cost of use.

[0033] Specifically, the driving component 25 includes a nut 251 rotatably mounted on the surface of the connecting block 2. The nut 251 is fixedly connected to one end of the worm 252. A worm wheel 253 that meshes with the worm 252 is fixedly connected to the screw 22. By setting the driving component 25, during operation, a tool can be used to rotate the nut 251, causing the nut 251 to drive the worm 252 to rotate, which in turn causes the worm 252 to drive the worm wheel 253 to rotate, which in turn causes the worm wheel 253 to drive the screw 22 to rotate.

[0034] Furthermore, the surface of the connecting block 2 is provided with a groove 27, and the nut 251 is located in the groove 27. The opening of the groove 27 is magnetically connected to a cover plate 28. By setting the groove 27 and the cover plate 28, the nut 251 can be protected, and the powder generated during the trimming process can be prevented from contaminating the nut 251.

[0035] In practical use, the working principle of this utility model is as follows:

[0036] First, install the trimming head 3 by inserting the mounting block 31 of the trimming head 3 into the mounting groove 21, allowing the dovetail block 26 to slide along the dovetail groove 33 to limit the trimming head 3's movement. Then, use a tool to rotate the nut 251, causing the nut 251 to rotate the worm 252, which in turn rotates the worm wheel 253, which in turn rotates the screw 22. This causes the screw 22 to move the movable block 23 along the guide rod 29, allowing the movable block 23 to move the locking block 24 into the locking groove 32 of the mounting block 31, thus locking the mounting block 31 into the mounting groove 21 and completing the installation of the trimming head 3.

[0037] When using the device, the operator can hold the anti-slip texture 11 part of the holding rod 1, and then bring the dressing head 3 close to and contact the grinding wheel for dressing.

[0038] After the trimming head 3 is damaged, the drive component 25 only needs to rotate the screw 22 in the opposite direction to move the locking block 24 out of the locking groove 32, and the trimming head 3 can be removed and replaced separately, reducing the cost of use.

[0039] In summary, this manual dressing device for the grinding wheel of the fine grinding mill, by setting up the mounting block 31 and the mounting groove 21, allows the dressing head 3 to be removed and replaced separately after it is damaged, thus reducing the cost of use.

[0040] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
