It also reduces the frequency of equipment cleaning and maintenance, extending the chuck's service life by more than 30%. The chuck dust cover fixture is mainly used in the manufacturing and assembly of chuck dust covers. During machining, it accurately positions the dust cover, ensuring that the dimensional accuracy of each part meets requirements, avoiding machining errors caused by positional deviations, and improving machining quality and efficiency. During assembly, the fixture assists workers in quickly and accurately installing the dust cover onto the chuck and other components, ensuring assembly consistency and stability, and reducing errors caused by manual operation. Furthermore, the fixture's structural design protects the dust cover during machining and assembly, preventing scratches or other damage to its surface. It also facilitates operation, reducing worker workload. It is a key tool for improving process quality and ensuring product quality in the production and assembly of chuck dust covers.

[0003] Currently, existing chuck dust cover fixtures are typically fixed in place using bolts connected to the bolt holes on the flange. However, after long-term use, the bolts used for fixing may loosen due to vibrations generated during equipment operation. Over time, this can cause the entire chuck dust cover fixture to wobble, thus reducing its stability during use. Utility Model Content

[0004] The purpose of this utility model is to provide a chuck dust cover fixture, which aims to solve the problem that existing chuck dust cover fixtures are usually fixed by bolts connected to the bolt holes on the flange during installation. However, after long-term use, the bolts used for fixing may loosen due to vibrations generated during equipment operation. Over time, this may cause the entire chuck dust cover fixture to shake, thereby reducing its stability during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chuck dust cover tooling, including a connecting base, a connecting flange fixedly connected to the top of the connecting base, an upper connecting piece fixedly connected to the top of the connecting flange, three bolt connection holes distributed in a ring on the surface of the connecting flange, a first annular groove formed on the inner side of the three bolt connection holes, and a rubber gasket bonded to the inner side of the first annular groove.

[0006] As a preferred tooling for the chuck dust cover of this utility model, the top of the rubber gasket has multiple grooves.

[0007] As a preferred tooling for the chuck dust cover of this utility model, the plurality of grooves are distributed in a ring with equal spacing.

[0008] As a preferred embodiment of the dust cover tooling for the chuck of this utility model, the top cross-section of the upper connecting member is arc-shaped.

[0009] As a preferred embodiment of the chuck dust cover tooling of this utility model, the bottom of the connecting flange is provided with a second annular groove, and a sealing ring is bonded to the inner side of the second annular groove.

[0010] As a preferred tooling for the chuck dust cover of this utility model, the bottom of the connecting flange is provided with three assembly slots, and the three assembly slots are distributed in a ring with equal spacing between them.

[0011] As a preferred embodiment of the chuck dust cover tooling of this utility model, the three assembly slots are connected to the second annular slot, and the sidewalls of the three assembly slots are chamfered at 45°.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By creating a first annular groove inside the three bolt connection holes, and then adhering a rubber washer to the inner side of the first annular groove, the top of the rubber washer will protrude from the first annular groove. When the bolt passes through the bolt connection hole to fix the chuck dust cover fixture, the end of the bolt will contact the top of the rubber washer, and the rubber washer will be compressed when tightened. The resulting elastic force can maintain the preload. At the same time, the annular grooves on the top of the rubber washer can increase the friction between the bolt and the contact surface, thereby further improving the stability of the chuck dust cover fixture after installation.

[0013] By creating a second annular groove at the bottom of the connecting flange and bonding a sealing ring within it, the sealing ring will fit against the contact surface after the chuck dust cover fixture is installed and fixed via the connecting flange, thus improving the sealing performance. Furthermore, by creating an assembly groove at the bottom of the connecting base, when the sealing ring needs to be replaced, the operator can easily remove it by inserting a tool into the second annular groove through the assembly groove and then prying the sealing ring out of the second annular groove, thus facilitating the subsequent replacement of worn sealing rings.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 The present invention provides the following technical solution: a chuck dust cover tooling, including a connecting base 1, a connecting flange 2 fixedly connected to the top of the connecting base 1, an upper connecting piece 3 fixedly connected to the top of the connecting flange 2, three bolt connection holes 4 distributed in an annular pattern on the surface of the connecting flange 2, a first annular groove 5 opened on the inner side of the three bolt connection holes 4, and a rubber gasket 6 bonded to the inner side of the first annular groove 5.

[0018] Preferably, the top of the rubber gasket 6 has multiple grooves 7, which are distributed in a ring at equal intervals.

[0019] In practical use, a first annular groove 5 is opened inside the three bolt connection holes 4, and then a rubber washer 6 is glued to the inner side of the first annular groove 5. At this time, the top of the rubber washer 6 will protrude from the first annular groove 5. When the bolt passes through the bolt connection hole 4 to fix the chuck dust cover fixture, the end of the bolt will contact the top of the rubber washer 6, and the rubber washer 6 will be compressed when tightened. The resulting elastic force can maintain the preload. At the same time, the annularly distributed grooves 7 on the top of the rubber washer 6 can increase the friction between the bolt and the contact surface, thereby further improving the stability of the chuck dust cover fixture after installation.

[0020] Preferably, the top cross-section of the upper connector 3 is arc-shaped.

[0021] Preferably, the bottom of the connecting flange 2 is provided with a second annular groove 8, the inner side of the second annular groove 8 is bonded with a sealing ring 9, the bottom of the connecting flange 2 is provided with three assembly grooves 10, and the three assembly grooves 10 are distributed in an annular pattern with equal spacing, the three assembly grooves 10 are connected to the second annular groove 8, and the sidewalls of the three assembly grooves 10 are chamfered at 45°. It should be noted that the 45° chamfered sidewalls of the assembly groove 10 make it easier to insert tools, and the three equally spaced annularly distributed assembly grooves 10 allow workers to remove the rubber gasket 6 from the groove 7 from different positions, thus addressing the situation where the rubber gasket 6 breaks and is difficult to remove.

[0022] In practical use, a second annular groove 8 is opened at the bottom of the connecting flange 2, and a sealing ring 9 is bonded in the second annular groove 8. After the chuck dust cover tooling is installed and fixed through the connecting flange 2, the sealing ring 9 will fit against the contact surface, thereby improving the sealing performance. Furthermore, by opening an assembly groove 10 at the bottom of the connecting base 1, when the sealing ring 9 needs to be replaced, the operator can remove it by inserting a tool into the second annular groove 8 through the assembly groove 10 and then prying the sealing ring 9 out of the second annular groove 8, thus facilitating the subsequent replacement of the worn sealing ring 9.

[0023] Working principle: First, a first annular groove 5 is made inside the three bolt connection holes 4. Then, a rubber washer 6 is adhered to the inner side of the first annular groove 5. At this time, the top of the rubber washer 6 will protrude from the first annular groove 5. Then, when the bolt passes through the bolt connection hole 4 to fix the chuck dust cover fixture, the end of the bolt will contact the top of the rubber washer 6. The rubber washer 6 will be compressed when tightened, and the resulting elastic force can maintain the preload. At the same time, the annularly distributed grooves 7 on the top of the rubber washer 6 can increase the friction between the bolt and the contact surface, thereby further improving the chuck's performance. The stability of the dust cover fixture after installation is improved. By opening a second annular groove 8 at the bottom of the connecting flange 2 and bonding the sealing ring 9 in the second annular groove 8, the sealing ring 9 will fit against the contact surface after the dust cover fixture is installed and fixed by the connecting flange 2, thereby improving the sealing performance. Furthermore, by opening an assembly groove 10 at the bottom of the connecting base 1, when the sealing ring 9 needs to be replaced, the operator can remove it by inserting a tool into the second annular groove 8 through the assembly groove 10 and then prying the sealing ring 9 out of the second annular groove 8, thus facilitating the subsequent replacement of the worn sealing ring 9.

[0024] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
