[0021] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0022] It should be noted that like reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not require further detailed discussion and description in the description of the subsequent drawings.

[0023] like Figure 1-3 As shown, the fiberglass rubber cutting saw blade groove grinding fixture includes: a base 1, a bearing seat 2 and a core shaft 3.

[0024] The base 1 is provided with a slide groove 4, and the bottom of the bearing seat 2 is provided with a slide table 5 matching the slide groove 4. The slide table 5 is provided with a T-shaped slide hole 6. In this embodiment, two T-shaped slide holes 6 are provided, and a T-shaped limit block 7 is slidably provided in the T-shaped slide hole 6. The T-shaped limit block 7 is fixedly connected to the base 1 by bolts. The bearing seat 2 can move along the slide groove 4 through the slide table 5, and its moving range is determined by the length of the T-shaped slide hole 6. Among them, the bearing seat 2 and the slide table 5 are both provided with through holes at the center position, which are used for screws to penetrate the bearing seat 2 and the slide table 5 in turn to fix the two.

[0025] The bearing seat 2 is convex, and the bearing seat 2 is composed of a seat plate 8 and a protrusion 9. A bearing 10 is arranged on the outside of the protrusion 9, and the inner ring of the bearing 10 is fixedly connected to the bearing seat 2; a groove is arranged on the bottom surface of the core shaft 3, and the inner wall of the groove is fixedly connected to the outer ring of the bearing 10. The core shaft 3 is rotatably connected to the bearing seat 2 through the bearing 10.

[0026] Furthermore, the core shaft 3 is stepped, and the core shaft 3 consists of a first step 11, a second step 12 and a third step 13 from bottom to top, and their cross-sections are all circular, and the diameters decrease successively; the side wall of the second step 12 is outer-circularly provided with a ratchet ring 14, and the ratchet ring 14 is fixedly connected to the first step 11 by bolts, and the outer ratchet teeth of the side wall of the ratchet ring 14 correspond to the groove 16 to be cut of the fiberglass rubber cutting saw blade 15, and the side wall of the third step 13 is used to sleeve the fiberglass rubber cutting saw blade 15, and the bottom surface of the fiberglass rubber cutting saw blade 15 is in contact with the top of the second step 12.

[0027] In addition, the fiberglass rubber cutting saw blade groove grinding fixture also includes an open pressure plate 17 and a locking nut 18. The diameter of the open pressure plate 17 is larger than the diameter of the third step 13. The locking nut 18 penetrates the open pressure plate 17 to the core shaft 3, clamping the fiberglass rubber cutting saw blade 15 between the open pressure plate 17 and the second step 12.

[0028] Furthermore, a support block 19 is provided on the side wall of the first step 11 , and a shoulder screw 20 is provided on the support block 19 . A torsion spring 21 and a pawl 22 are provided on the outer sleeve of the shoulder screw 20 . The torsion spring 21 enables the pawl 22 to maintain engagement with the outer ratchet of the ratchet ring 14 .

[0029] When in use, a slotting device is provided on the outside, and its slotting output end is fixed. The on-site staff pushes the bearing seat 2 to slide toward the slotting device. When the bearing seat 2 moves to the limit position, the slotting device completes a slotting of the fiberglass rubber cutting saw blade 15. The staff pulls the bearing seat 2 back, away from the slotting device, and rotates the bearing seat 2. When the pawl 22 is engaged with the outer ratchet on the side wall of the next ratchet ring 14, the rotation stops.

[0030] The staff repeats the above steps in sequence until the ratchet ring 14 rotates a full circle.

[0031] Among them, since the outer ratchet on the side wall of the ratchet ring 14 corresponds to the cutting groove 16 of the fiberglass rubber cutting saw blade 15, when grooving different types of fiberglass rubber cutting saw blades 15, it is only necessary to replace the corresponding ratchet ring 14, which is more convenient and improves the versatility of the equipment.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
