Description

Technical Field

[0001] This application relates to the field of shaft machining technology, and in particular to a machining debris shielding structure. Background Technology

[0002] When machining shaft-type workpieces, the shaft rotates rapidly, and the cutting tool approaches the shaft to complete the machining. To increase stability during the shaft machining process, such as... Figure 1 As shown, a stabilizer 4 is provided at the end of the shaft 5, and three bearings 41 are arranged at equal intervals along the circumference inside the stabilizer 4. The end of the shaft 5 is located between the three bearings 41 to reduce friction when the long shaft rotates.

[0003] However, during the turning process, chips are generated, which can easily splash onto the bearings. Due to the high-speed rotation of the shaft, the chips that splash between the shaft and the bearing can easily damage the workpiece, which needs to be improved. Utility Model Content

[0004] To reduce the amount of machining debris splashing between the shaft and the bearing, this application provides a machining debris shielding structure.

[0005] The processing debris shielding structure provided in this application adopts the following technical solution:

[0006] A chip shielding structure includes a shielding plate and a connecting assembly, wherein the connecting assembly is used to connect the shielding plate to the side of the stabilizer near the cutter head; the shielding plate has a movable hole for the shaft to pass through, and the inner wall of the movable hole abuts against the outer wall of the shaft.

[0007] By adopting the above technical solution, the baffle plate is connected to the side of the stabilizer near the cutting head, which can effectively block the chips generated during turning and prevent chips from splashing onto the bearing, thereby avoiding damage to the shaft and bearing caused by chips. The movable hole in the baffle plate allows the shaft to pass through, and the inner wall of the movable hole abuts against the outer wall of the shaft, further reducing the possibility of chips passing through the gap between the movable hole and the shaft, and further improving the blocking effect.

[0008] Optionally, the connecting assembly includes a bolt, the baffle plate has a first threaded groove, the stabilizer has a second threaded groove for engaging with the first threaded groove, and the bolt engages with the first threaded groove and the second threaded groove.

[0009] By adopting the above technical solution, the connecting assembly utilizes the engagement of bolts with the first and second threaded grooves to achieve a detachable connection between the baffle plate and the stabilizer frame. This connection method is not only simple in structure and easy to operate, but also ensures the stability of the baffle plate installation, effectively preventing the baffle plate from loosening due to vibration or impact during processing, thereby better fulfilling its function of blocking debris and protecting the bearing from damage caused by flying debris.

[0010] Optionally, a plug-in post is provided on one side of the shield, and the stabilizer is provided with a plug-in slot for the plug-in post to be inserted.

[0011] By adopting the above technical solution, the cooperation between the plug and the slot can achieve rapid positioning between the shield and the stabilizer, ensuring accurate alignment of the two during installation.

[0012] Optionally, the connecting assembly includes a hinge plate and an elastic locking block. The hinge plate is rotatably mounted on the outer peripheral wall of the shield plate. The elastic locking block is disposed on one side of the hinge plate, and the outer peripheral wall of the stabilizer has an elastic slot for the elastic locking block to be inserted.

[0013] By adopting the above technical solution, the hinge plate is rotatably installed on the outer peripheral wall of the baffle plate, and the elastic block is engaged with the elastic slot on the stabilizer. This not only enables the quick installation and disassembly of the baffle plate, but also facilitates individual replacement when components are damaged, effectively improving the assembly efficiency and maintenance convenience of the overall structure.

[0014] Optionally, a reinforcing rod is provided on one side of the shield, and the outer wall of the reinforcing rod is covered with a rubber layer; the stabilizer is provided with a reinforcing groove for the reinforcing rod to be inserted.

[0015] By adopting the above technical solution, the elasticity of the rubber layer can increase the friction between the reinforcing rod and the stabilizer, thereby reducing the possibility of the reinforcing rod slipping in the reinforcing groove during the insertion of the elastic clip, and effectively improving the stability of the baffle after installation.

[0016] Optionally, the inner wall of the movable hole is provided with a rubber strip, and the inner wall of the rubber strip is provided with an arc surface for abutting against the outer wall of the shaft.

[0017] By adopting the above technical solution, a rubber strip is provided on the inner wall of the movable hole on the baffle plate, and the inner wall of the rubber strip is provided with an arc surface that abuts against the outer wall of the shaft, which can increase the friction between the inner wall of the movable hole and the shaft, thereby improving the stability of the baffle plate on the shaft.

[0018] Optionally, the outer wall of the rubber strip is coated with a wear-resistant coating.

[0019] By adopting the above technical solution, coating the outer wall of the rubber strip with a wear-resistant coating can effectively improve the wear resistance of the rubber strip and extend its service life.

[0020] Optionally, one side of the rubber strip is integrally formed with a connector strip, and the inner wall of the movable hole is provided with an installation groove for the connector strip to be inserted into, and the connector strip is interference-fitted with the installation groove.

[0021] By adopting the above technical solution, the interference fit between the insert strip and the mounting groove allows the rubber strip to be detachably installed on the inner wall of the movable hole. When the rubber strip becomes severely worn due to long-term use, it can be easily removed from the movable hole and replaced with a new rubber strip, thereby extending the overall service life of the baffle plate and ensuring that the protection effect on the shaft is always in good condition.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a baffle, the chips generated during the turning process can be effectively blocked, preventing chips from splashing onto the bearing and thus avoiding damage between the shaft and the bearing caused by chips;

[0024] 2. The interference fit between the insert strip and the mounting groove allows the rubber strip to be detachably installed on the inner wall of the movable hole, making it easy to remove it from the movable hole and replace it with a new rubber strip; and the inner wall of the rubber strip is provided with an arc surface that abuts against the outer wall of the shaft, which can increase the friction between the inner wall of the movable hole and the shaft, thereby improving the stability of the baffle on the shaft.

[0033] The following is in conjunction with the appendix Figures 2-7 This application will be described in further detail.

[0034] Example 1:

[0035] This application discloses a processing debris shielding structure.

[0036] Reference Figure 2 A chip shielding structure includes a shielding plate 1 and a connecting assembly 2. The shielding plate 1 is installed on the side of the stabilizer 4 near the cutter body, and the connecting assembly 2 is used to connect the shielding plate 1 and the cutter body.

[0037] Reference Figure 3 and Figure 4 The baffle plate 1 has a movable hole 11 for the shaft body 5 to pass through. In this embodiment, a rubber strip 3 is provided on the inner wall of the movable hole 11. The rubber strip 3 is arranged in a ring shape, that is, the two ends of the rubber strip 3 are connected. An arc surface 31 is provided on one side of the rubber strip 3, and the arc surface 31 is used to abut against the outer wall of the shaft body 5.

[0038] In this embodiment, the rubber strip 3 is coated with a wear-resistant coating. Coating the outer wall of the rubber strip 3 with a wear-resistant coating can effectively improve the wear resistance of the rubber strip 3 and extend its service life.

[0039] Reference Figure 4 One side of the rubber strip 3 has an integrally formed insert strip 32. The inner wall of the movable hole 11 has a mounting groove 12 for the insert strip 32 to be inserted and fitted. The interference fit between the insert strip 32 and the mounting groove 12 allows the rubber strip 3 to be disassembled and installed, so that the severely worn rubber strip 3 can be replaced, thereby extending the overall service life of the baffle plate 1 and ensuring that the protection effect on the shaft 5 is always in good condition.

[0040] Reference Figure 3 The connecting component 2 includes multiple bolts 21 and multiple plug-in posts 22. All plug-in posts 22 are located on one side of the shielding plate 1 and are arranged in a circumferential manner. The stabilizer 4 has a plug-in slot 43 for the plug-in posts 22 to be inserted. The insertion and engagement of the plug-in posts 22 and the plug-in slot 43 can increase the stability of the folding plate installed on the stabilizer 4.

[0041] The baffle plate 1 has a first threaded groove 13, and the stabilizer 4 has a second threaded groove 42 that is directly opposite to the first threaded groove 13. The bolt 21 engages with the first threaded groove 13 and the second threaded groove 42. The engagement of the bolt 21 with the first threaded groove 13 and the second threaded groove 42 enables a detachable connection between the baffle plate 1 and the stabilizer 4; this facilitates individual replacement of damaged components and effectively improves the assembly efficiency and maintenance convenience of the overall structure.

[0042] The implementation principle of Embodiment 1 of this application is as follows:

[0043] The baffle plate 1 is connected to the stabilizer 4 on the side near the cutting head, effectively blocking the chips generated during turning and preventing them from splashing onto the bearing 41. This avoids damage to the shaft 5 and bearing 41 caused by chips, improving the stability of the machining process. The baffle plate 1 has a movable hole 11 for the shaft 5 to pass through, and the rubber strip 3 abuts against the outer wall of the shaft 5, further reducing the possibility of chips passing through the gap between the movable hole 11 and the shaft 5, further enhancing the blocking effect.

[0045] This application discloses a processing debris shielding structure.

[0046] Reference Figure 5 and Figure 6 The difference between Embodiment 2 and Embodiment 1 is that the connecting component 2 includes a hinge plate 23, an elastic block 24, and a reinforcing rod 25. The reinforcing rod 25 is fixed to one side of the baffle plate 1, and the outer wall of the reinforcing rod 25 is covered with a rubber layer 26. A reinforcing groove 45 is provided on one side of the stabilizer 4 for the reinforcing rod 25 to be inserted. The insertion and cooperation between the reinforcing rod 25 and the reinforcing groove 45 can increase the installation of the baffle plate 1 on one side of the stabilizer 4, and the rubber layer 26 can increase the stability of the reinforcing rod 25 inserted into the reinforcing groove 45.

[0047] Reference Figure 7 The hinge plate 23 is rotatably mounted on the side wall of the folding plate, and a torsion spring 27 is provided at the hinge point between the hinge plate 23 and the cover plate 1; the elastic block 24 is fixed on one side of the hinge plate 23, and the outer peripheral wall of the stabilizer 4 is provided with an elastic slot 44 for the elastic block 24 to be inserted, and the elastic force of the torsion spring 27 is used to drive the elastic block 24 to be inserted into the elastic slot 44.

[0048] The implementation principle of Embodiment 2 of this application is as follows:

[0049] The hinge plate 23 is rotatably mounted on the outer peripheral wall of the shield plate 1. The elastic block 24 is inserted into the elastic slot 44 on the stabilizer 4, which not only enables the quick installation and disassembly of the shield plate 1, but also facilitates individual replacement when the component is damaged, effectively improving the assembly efficiency and maintenance convenience of the overall structure.
