Technical Field

[0001] This utility model relates to the field of water-based drilling and polishing machine technology, and in particular to a grinding and polishing machine indexing fork device. Background Technology

[0002] The indexing fork is a key component in a grinding and polishing machine used to drive the rotation of the clamping worm gear. It achieves the angle adjustment function of the clamping pin by meshing with the worm gear.

[0003] In the prior art, such as the indexing device of a diamond grinding and polishing machine disclosed in patent publication number CN217914502U, an indexing fork is fixedly installed on the slide and driven to rotate by the fork drive component.

[0004] However, when grinding and polishing machines process high-precision workpieces such as diamonds, the alignment accuracy of the indexing fork and worm gear is extremely high. If the indexing fork experiences slight collisions or wear due to angular deviations, vibrations, or uneven loads during sliding or rotation, it can easily damage the contact surface between the fork connector on the indexing fork and the worm gear, thereby affecting the adjustment accuracy and service life of the clamping pin.

[0005] The existing indexing fork generally has an integrated structure where the indexing shaft and the fork connector are installed in the bearing housing and are not easily disassembled. As a result, when the fork connector needs to be replaced due to wear, the entire unit must be replaced or the fork must be sent back to the factory for repair, which significantly increases maintenance costs. Utility Model Content

[0006] This utility model proposes a dividing fork device for a grinding and polishing machine. Through modular design, it can be replaced individually, avoiding overall scrapping, significantly reducing the cost of use, and solving the above-mentioned problems existing in the use of the prior art.

[0020] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example: like Figures 1 to 6As shown, this utility model discloses a grinding and polishing machine indexing fork device, including a bearing seat 1, an indexing shaft 2, and a fork connector 3. The indexing shaft 2 is rotatably fitted in the bearing seat 1 through a bearing 6. Both ends of the indexing shaft 2 protrude from the bearing seat 1. The fork connector 3 is detachably connected to one end of the indexing shaft 2. Two symmetrically arranged indexing seats 31 are provided on the end of the fork connector 3 away from the indexing shaft 2. The two indexing seats 31 are detachably connected to an indexing plate 4 on their opposite side. The indexing plate 4 is made of chromium-containing steel and has been quenched. It is in direct contact with the worm gear and is a vulnerable part that can be replaced separately.

[0022] The detachable connection between the indexing shaft 2 and the fork connector 3 is as follows: a cross-shaped connector 21 is integrally formed on the end of the indexing shaft 2 facing the fork connector 3, while a cross-shaped slot socket 32 ​​is integrally formed on the end of the fork connector 3 facing the indexing shaft 2. The cross-shaped slot socket 32 ​​has a cross-shaped slot 321 for the cross-shaped connector 21 to be inserted into. The cross-shaped connector 21 is inserted into the cross-shaped slot 321 of the cross-shaped slot socket 32, forming a stable connection. The cross-shaped design ensures that the indexing shaft 2 and the fork connector 3 can be quickly aligned during assembly, reducing installation errors and enhancing connection strength.

[0023] Furthermore, the shift fork connector 3 also has a receiving groove 33 at the end away from the indexing shaft 2, and a connecting post 22 is integrally formed on the cross connector 21. The shift fork connector 3 has a through hole 34 at the bottom of the receiving groove 33, through which the connecting post 22 passes and enters the receiving groove 33. The connecting post 22 is provided with a fixing mechanism for fixing the shift fork connector 3. The fixing mechanism specifically includes a fixing member 51 that abuts against the bottom of the receiving groove 33, and a threaded opening 23 on the connecting post 22. A screw 52 is threaded onto the threaded opening 23. The screw 52 is used to fix the fixing member 51 to the connecting post 22. By tightening the screw 52, ​​the fixing member 51 locks the shift fork connector 3 onto the cross connector 21, realizing a stable connection between the shift fork connector 3 and the indexing shaft 2. When disassembling, the parts can be separated simply by loosening the screw 52.

[0024] The indexing shaft 2 is supported and limited as follows: Several bearings 6 are provided in the bearing housing 1, and the indexing shaft 2 is rotatably fitted in the bearings 6. In addition, a limiting plate 24 is integrally formed between the indexing shaft 2 and the cross connecting seat 21. The end of the cross groove socket 32 ​​abuts against the limiting plate 24. The limiting plate 24 prevents the indexing shaft 2 from axially displacing. In addition, a snap ring mounting groove 25 is provided on the side of the bearing housing 1 away from the limiting plate 24. A snap ring can be installed on the snap ring mounting groove 25 to further fix the position of the indexing shaft 2 and ensure operational stability.

[0025] The detachable connection between the indexing seat 31 and the indexing plate 4 is as follows: The indexing seat 31 has several screw passage ports 311, and the indexing plate 4 has internally threaded connection holes 41 corresponding to the screw passage ports 311. The indexing plate 4 is fixed to the indexing seat 31 by passing a screw 52 through the screw passage port 311 and screwing it into the internally threaded connection hole 41. The hardening treatment of the indexing plate 4 gives it high wear resistance, but it can still be replaced individually by removing the screw 52 after wear, without needing to replace the entire shift fork connector 3, significantly reducing operating costs. The symmetrically arranged indexing plates 4 can balance the force and reduce the risk of unilateral wear.

[0026] In this invention, a sealing shell 7 is fixedly connected to the bearing housing 1. Specifically, the sealing shell 7 is threaded onto the outside of the bearing housing 1. The sealing shell 7 extends from the bearing housing 1 to the outside of the shift fork connector 3, enclosing the cross connector 21, the cross groove socket 32, and the shift fork connector 3. Inside the sealing shell 7, a sealing ring 8 is located on the outside of the shift fork connector 3. The sealing ring 8 can be replaced by any other sealing structure, which is common knowledge to those skilled in the art. It serves to prevent external dust and water mist from entering the bearing housing 1 and the transmission components.

[0027] An opening 11 is also fixed on the bearing seat 1 to enable the present invention to be fixed on a slide in the prior art.
