Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0026] As shown in Figure 1 The utility model discloses an embodiment provides a deburring device, including connecting assembly 2 and spline roller 1. Connecting assembly 2 is used for connecting spline roller 1 on lathe tool tower, and spline roller 1 is configured to rotate around its axis. The spline of spline roller 1 and the spline of the part to be deburred have the same modulus. And the spline tooth number of spline roller 1 and the spline tooth number of the part are relatively prime.

[0027] After the lathe slotting, spline roller 1 is connected on lathe tool tower through connecting assembly 2. The part to be deburred is connected with power source and can rotate. And spline roller 1 has no power source and cannot rotate by itself. Therefore, make spline roller 1 close to the groove of the part and mesh with the spline of the part, then spline roller 1 will rotate with the part. With the rotation of spline roller 1, the spline of spline roller 1 and the spline of the part are extruded, so that the burr on the spline of the part can be flattened, realizing the deburring of the spline of the part. The spline of spline roller 1 and the spline of the part to be deburred have the same modulus, in order to make the spline of spline roller 1 mesh with the spline of the part. The spline tooth number of spline roller 1 and the spline tooth number of the part are relatively prime, which can avoid the teeth on the spline of the part mesh with the same teeth on spline roller 1, so that different teeth on spline roller 1 will mesh with the teeth on the spline of the part, so that the burr on the spline of the part is stressed more evenly, and the burr removal effect is better. By setting spline roller 1, the deburring of the spline of the part is realized by spline roller 1, which saves manpower and reduces the work load of workers. At the same time, the probability of error caused by machinery is smaller than that caused by manual work, so the use of spline roller 1 can also reduce the damage to the part.

[0028] Further, the pressure angle of the spline of spline roller 1 and the pressure angle of the spline of the part are different. By setting the pressure angle of the spline of spline roller 1 and the pressure angle of the spline of the part to be different, the meshing is more compact when the spline of spline roller 1 and the spline of the part mesh, so that the pressure on the protruding burr is greater, and the burr removal effect is better.

[0029] Further, the spline of the spline roller 1 is provided with a helix angle, that is, the spline teeth of the spline roller 1 are inclined teeth. By setting the helix angle, the radial cutting force can be increased, thereby facilitating the removal or flattening of the protruding burrs.

[0030] Further, the spline roller 1 is provided with a drain groove. During the removal of the burrs, some waste will be generated. The generated waste can be discharged through the drain groove, preventing the waste from affecting the removal of the burrs.

[0031] Further, as shown in Figure 1 and Figure 2 , the connecting assembly 2 includes a support 21, a fixed head 22, and a connecting rod 23. The support 21 is fixedly connected to the lathe tool turret. One end of the connecting rod 23 is connected to the support 21, and the other end of the connecting rod 23 is connected to the fixed head 22. The spline roller 1 is rotatably connected to the fixed head 22. A mounting groove 211 is formed in the side wall of the support 21, and the length direction of the mounting groove 211 is the same as the length direction of the connecting rod 23. The connecting rod 23 is slidably arranged along the length direction of the mounting groove 211. A spring 3 is arranged in the mounting groove 211, and the spring 3 is arranged along the length direction of the mounting groove 211. One end of the spring 3 is fixedly connected to the bottom of the mounting groove 211, and the other end is fixedly connected to the connecting rod 23.

[0032] By arranging the spring 3 on the support 21 and connecting the spring 3 with the connecting rod 23, when the spline roller 1 is close to the part for burr removal, the spline roller 1 can float, preventing damage due to collision between the spline roller 1 and the part. The floating of the spline roller 1 relies on the extension and contraction of the spring 3. When the spring 3 extends and contracts, the connecting rod 23 will slide in the mounting groove 211 along the length direction of the mounting groove 211.

[0033] Further, as shown in Figure 2 , the connecting rod 23 is arranged as a T-shaped rod. The connecting rod 23 includes a first connecting rod 231 and a second connecting rod 232, which are connected perpendicularly to each other. An end cover 4 is arranged at the slot opening of the mounting groove 211, and a through hole 41 is formed in the end cover 4. The second connecting rod 232 is arranged in the mounting groove 211, and the end of the first connecting rod 231 away from the second connecting rod 232 extends out of the mounting groove 211 through the through hole 41 and is connected to the fixed head 22. The diameter of the through hole 41 is smaller than the length of the second connecting rod 232, so as to prevent the second connecting rod 232 from sliding out of the mounting groove 211. When the connecting rod 23 slides in the mounting groove 211, the second connecting rod 232 is fixedly connected to one end of the spring 3. When the second connecting rod 232 slides to the through hole 41, since the diameter of the through hole 41 is smaller than the length of the second connecting rod 232, the second connecting rod 232 cannot pass through the through hole 41, and the end cover 4 limits the second connecting rod 232.

[0034] In some other embodiments of the present application, the end of the connecting rod connected with the spring is provided with a limiting head. A limiting block is arranged at the slot opening of the mounting slot, and the limiting block is used to prevent the limiting head from falling out of the mounting slot. The limiting block functions to limit the limiting head, and at this time, the limiting head is equivalent to the second connecting rod, and the limiting block is equivalent to the end cover.

[0035] Further, as shown in Figure 4 , the end cover 4 is detachably connected to the side wall of the support 21. Alternatively, the end cover 4 is fixedly connected to the support 21 by four screws 42. By arranging the end cover 4 to be detachable, the installation and replacement of the spring 3 and the connecting rod 23 are facilitated. At the same time, the detachable connection by the screws 42 is simple in structure and convenient to operate.

[0036] Further, as shown in Figure 2 and Figure 3 , the fixed head 22 is detachably connected with the connecting rod 23. Alternatively, the fixed head 22 is fixedly connected with the end of the connecting rod 23 protruding out of the mounting slot 211 by the countersunk head bolt 5. Correspondingly, the countersunk hole 221 is formed in the side wall of the fixed head 22.

[0037] Further, as shown in Figure 2 and Figure 3 , the fixed head 22 is arranged in a U-shaped plate structure, and the connecting rod 23 is connected to the bottom of the fixed head 22, that is, the outer bottom surface of the U-shaped groove of the fixed head 22. The pin shaft 6 is arranged through the opposite two side walls of the fixed head 22, and the spline roller 1 is located in the U-shaped groove of the fixed head 22 and is coaxially and rotatably connected to the pin shaft 6. Arranging the fixed head 22 in a U-shaped plate structure facilitates the connection of the spline roller 1 with the fixed head 22. At the same time, coaxially and rotatably connecting the spline roller 1 to the pin shaft 6 is relatively simple in structure.

[0038] Further, as shown in Figure 2 and Figure 3 , the end of the pin shaft 6 away from the plug is provided with a through hole 6141 perpendicular to the length direction of the pin shaft 6. The clamping piece 62 is arranged through the through hole 6141 to prevent the pin shaft 6 from falling off the fixed head 22. Limiting the pin shaft 6 by the clamping piece 62 is simple in structure and facilitates disassembly to replace the spline roller 1 in case of long-term use and wear.

[0039] Alternatively, as shown in Figure 2 and Figure 3 , the countersunk hole 221 is formed in the bottom of the U-shaped plate.

[0040] Further, as shown in Figure 3As shown, the spline roller 1 is provided with a concentric hole, and a bearing 7 is coaxially arranged in the concentric hole. The spline roller 1 is rotatably connected with the pin shaft 6 through the bearing 7. Optionally, the bearing 7 is a needle bearing. By arranging the bearing 7, the rotation of the spline roller 1 is smoother. Meanwhile, the wear of the spline roller 1 caused by the pin shaft 6 is reduced.

[0041] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
