Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel debugging, in particular to a fixture which is convenient for adjusting the tightness of a grinding wheel fastening disc. Background Art

[0002] In some industrial scenarios, the surface of soft products needs to be polished, and grinding with a grinding wheel is one of the polishing methods. During the grinding process, the sandpaper on the surface of the grinding wheel rotates at high speed along with the grinding wheel, and the sandpaper is prone to fall off. At this time, the fastening disk needs to be loosened. After tightening the sandpaper, the fastening disk needs to be tightened. However, since the space where the fastening disk, i.e., the chuck, is located is very small, it is inconvenient for the operator to use conventional tools to adjust it, which affects the work efficiency.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0026] like Figure 1-2 As shown, in one embodiment, a jig for adjusting the tightness of a fastening disk of a grinding wheel 3 includes a jig body, and the jig body is engaged with the circumference of a chuck 4 and openings 5 ​​uniformly provided outside the circumference of the chuck 4;

[0027] The utility model also includes a handle 2, which is fixedly connected to the jig body. After the jig body and the chuck 4 are fixed, the chuck 4 can be loosened or tightened by applying force through the handle 2. By using the jig, the chuck 4 can be adjusted conveniently and quickly, thereby improving work efficiency and reducing the impact on the polishing process.

[0028] For further information, please refer to Figure 1 The fixture body includes an arc-shaped portion 11 adapted to the circumference of the chuck 4 and an embedded portion 12 engaged with the opening 5 opened on the circumference of the chuck 4. In this embodiment, the two are integrally formed and are made of metal. The embedded portion 12 is arranged at the head end of the arc-shaped portion 11. The embedded portion 12 is hook-shaped. When the embedded portion 12 is inserted into the opening 5, the arc-shaped portion 11 can fit on the outer surface of the circumference of the chuck 4, so that when the handle 2 is used to apply force, the chuck 4 can be driven to rotate.

[0029] The size of the embedded portion 12 is adapted to the inner diameter of the opening 5. It should be noted that the size here refers to the width and thickness of the embedded portion 12. The two sizes are adapted so that the embedded portion 12 can fit tightly with the opening 5, so that when the handle 2 applies force, the chuck 4 can be driven to rotate. Preferably, the width of the embedded portion 12 is 2-2.5 cm, and the size of the entire embedded portion 12 shows a trend of gradually decreasing, so it can be adapted to openings 5 ​​of more sizes. If the inner diameter of the opening 5 is small, the depth of the embedded portion 12 inserted into the opening 5 is shallow. If the inner diameter of the opening 5 is large, the depth of the embedded portion 12 inserted into the opening 5 is deep.

[0030] The connection between the fixture body and the handle 2 can be one-piece molding, welding or fixed connection by bolts, as long as the two are stably connected.

[0031] The arc portion 11 and the embedded portion 12 are roughened on the side in contact with the circumferential surface of the chuck 4 so as to make the circumferential connection with the chuck 4 tighter and reduce the risk of slipping.

[0032] Working principle: Figure 3-4 When the chuck 4 of the grinding wheel 3 needs to be adjusted, the jig only needs to be stuck in the opening 5, the handle 2 is gently pressed by hand, and the grinding wheel 3 is rotated by hand to adjust the tightness of the fastening disk of the grinding wheel 3. With the assistance of this jig, the work efficiency is greatly improved.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
