[0002] Deburring is a process used to remove burrs or flash formed on the edges of parts during machining. Due to the irregular shape of parts, deburring operations often involve problems such as irregular geometric features of the machining area and inconsistent chamfer contours, which increases the requirements for tool posture adaptability.

[0003] Currently, floating mechanisms are used to compensate for the movement between the tool and the drive unit. However, the existing floating mechanisms are complex in structure, which leads to complicated assembly and debugging processes, thereby increasing production and maintenance costs.

Detailed Implementation

[0017] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] See appendix Figure 1 To be continued Figure 8 The present invention provides a radial floating mechanism, including a connecting base 1, a floating joint 4 and a positioning sleeve 2. The floating joint 4 is rotatably connected to the connecting base 1 through a rotating shaft 5, and then limited by the positioning sleeve 2 to control the swing range of the floating joint 2 in the lateral direction (the lateral direction is the radial direction of the connecting base).

[0019] Specifically, one axial end of the connecting base 1 is used to connect to a drive source, providing power input to the radial floating mechanism. The other axial end has a mounting portion 11 along its longitudinal axis. The positioning sleeve 2 is coaxially arranged with the connecting base 1, and the positioning sleeve 2 is detachably fitted onto the mounting portion 11 via a locking member 6. The positioning sleeve 2 surrounds the mounting portion 11 to form a top-opening receiving cavity 3. The floating connector 4 includes a floating portion 41 and a connecting portion 42 integrally connected to the floating portion 41 for mounting a tool. Here, the tool is often a deburring and chamfering tool (see attached diagram). Figure 8(As shown). The floating part 41 is inserted into the receiving cavity 3 and is movably connected to the mounting part 11 through the rotating shaft 5. The floating joint 4 can swing laterally relative to the connecting base 1 around the rotating shaft 5.

[0020] Therefore, the radial floating mechanism provided in this embodiment has regular parts shapes, which is convenient for production and processing; the overall structure is simple and easy to assemble and produce. This mechanism can realize the flexible radial floating of the tool through a simple structure, which reduces production and maintenance costs while meeting the usage requirements.

[0021] It should be noted that the positioning sleeve is used to limit the swing range of the floating joint, and therefore its axial length is not limited. The setting method can be found in the appendix. Figure 7 and attached Figure 8 .

[0022] Furthermore, the mounting portion 11 is a U-shaped longitudinal groove formed in the middle of the other end of the connecting base 1, which includes two inner planar walls 111 arranged opposite each other along the longitudinal direction, and a groove bottom surface 112 connected to the bottom of the two inner planar walls 111; there is a gap between the two side planar walls 411 of the floating portion 41 and the two inner planar walls 111 to ensure that the floating joint will not get stuck when it swings, ensuring the flexibility of the swing. At the same time, the U-shaped longitudinal groove provides guidance for the swing of the floating joint, ensuring that the floating joint swings radially and ensuring the consistency of the swing. In addition, there is an activity space A31 between the bottom plane 412 of the floating portion 41 and the groove bottom surface 112, providing sufficient freedom of movement for the bottom of the floating joint (i.e., in the longitudinal direction) to ensure the reliability of the floating mechanism.

[0023] Furthermore, the positioning sleeve 2 closes the two lateral openings of the mounting part 11 to form the receiving cavity 3; the two lateral side walls of the floating part 41 are respectively provided with movable spaces B32 between them and the positioning sleeve 2, which provides the floating joint with a degree of freedom in the radial direction, so that it can form a certain tilt angle or swing angle relative to the longitudinal axis, thereby meeting the flexible swing requirements in the actual working process.

[0024] Furthermore, to ensure the elastic adjustment of the floating joint in its working position, the cutting edge of the tool is offset relative to the longitudinal axis X by a cutting path corresponding to a cutting radius R. The floating part 41 is provided with a first adjustment hole 413, which extends laterally through the floating part 41 and is located near the top opening of the receiving cavity 3. A spring 7 and a screw A8 for adjusting the deformation of the spring 7 are provided within the first adjustment hole 413. One end of the spring 7 elastically abuts against the screw A8, and the other end elastically abuts against the inner wall of the positioning sleeve 2. The positioning sleeve 2 has a first through hole 21, which is coaxial with the first adjustment hole 413 and located near the screw A8. The screw A8 is adjusted by extending through the first through hole 21 into the first adjustment hole 413. The spring 7 is a helical spring, which applies a force to the floating joint 4 relative to the inner wall of the positioning sleeve 2. This force causes the upper end of the floating part 41 to contact the upper end of the positioning sleeve 2, thereby pressing the floating joint against the positioning sleeve. The range of action of spring 7 can be adjusted by screw A8 set in the first adjustment hole 413 to realize the elastic adjustment of the floating joint in the working position and meet the needs of dynamic cutting path of the tool blade under different cutting conditions.

[0025] Furthermore, in order to adjust the cutting radius R, the floating part 41 is also provided with a second adjustment hole 414. The second adjustment hole 414 is in the same direction as the first adjustment hole 413 and is spaced apart. A screw B9 is connected inside the second adjustment hole 414. The end of the screw B9 facing away from the other end of the spring 7 protrudes out of the second adjustment hole 414 and abuts against the inner wall of the positioning sleeve 2.

[0026] Specifically, the positioning sleeve 2 has a second through hole 22 on the side opposite to the first through hole 21. The second through hole 22 is coaxially arranged with the second adjusting hole 414. The length of the screw B9 protruding from the second adjusting hole 414 is adjusted by the second through hole 22 extending into the second adjusting hole 414. The protruding part of the screw B9 is used to limit the tilt angle or swing angle of the floating joint around the rotation axis 5 and form a corresponding minimum distance d to adjust the cutting radius.

[0027] Furthermore, the connecting portion 42 is provided with a longitudinally extending shaft hole 421 for connecting the tool holder and a transversely extending locking hole 422 communicating with the shaft hole 421 for accommodating fasteners to lock the tool holder. The longitudinal axis of the shaft hole 421 is either coincident or parallel to the longitudinal axis of the connecting base 1. Specifically, when the longitudinal axis of the shaft hole 421 coincides with the longitudinal axis X, the tool is offset relative to the longitudinal axis X by a cutting path corresponding to the cutting radius R. When the longitudinal axis of the shaft hole 421 is parallel to the longitudinal axis X, the corresponding cutting radius of the tool is R plus the distance between the shaft hole 421 and the longitudinal axis, to adapt to the needs of different cutting paths and improve the applicability of the floating mechanism.

[0028] In summary, the radial floating mechanism provided by this utility model has a simple structure and few parts, which facilitates production and maintenance by rotatably connecting the floating joint to the connecting base through a rotating shaft and limiting the swing angle through a positioning sleeve. In addition, by setting a spring, the floating joint can be elastically adjusted in the working position, so that the tool can meet different cutting conditions. By setting screw B, the cutting radius of the tool can be adjusted, which improves the adaptability and flexibility of the floating mechanism and meets diverse cutting needs.
