As shown in fig. 3-5, the rotation chuck 11 rotates around the power output shaft 3 in the circumferential direction, and the middle bevel gear carrier 10 is driven to rotate around the power output shaft 3 in the axial direction by the clamping groove structure, and the protrusion on the rear end surface of the rotation chuck 11, which is pushed by the rotation spring 2, is embedded in the concave groove on the power output mechanism 1, so that the radial position of the rotation chuck 11 is locked.

The helical angle of each helical gear is 45 degrees, so that the vertical steering function of power is realized, the bearing capacity is increased, the impact force and noise are effectively reduced, and in addition, the helical gear transmission is adopted to increase the transmission stability, so that the highest rotating speed of the polishing machine is increased.
In the angle limiting device 9, the limit switch cover 16 is screwed into the axial end part of the hinge shaft clockwise around the thread pair 14 to provide an axial inward extrusion force to the limit piston 15, and the limit piston 15 moves axially inward to provide pressure to the limit rotary spring 13 to increase the elastic potential energy of the limit rotary spring. When the latch at the tail end of the final limiting piston 15 extends into the limiting clamping groove 12 on the middle bevel gear carrier 6 and the tail end bevel gear carrier 10, the latch and the limiting clamping groove 12 are completely matched to be incapable of moving inwards, the limiting fixing function of the tail end polishing disc 7 in rotation is completed, the polishing disc 7 cannot rotate at the moment, and the rotation angle and the position cannot be adjusted.
On the contrary, when the limit switch cover 16 is screwed out from the axial end part of the hinge shaft counterclockwise around the thread pair 14, the limit piston 15 moves outwards along the axial direction under the pressure of the limit rotary spring 13, and after the tail end latch of the limit rotary spring is separated from the limit clamping groove 12, the polishing disc 7 is rotated again, the rotation angle is adjusted again, namely, a proper angle is selected to finish the work by using the polishing machine.
In specific implementation, the power output mechanism 1 is fixedly connected with a power-assisted handle, so that two hands can work together conveniently to achieve a better polishing effect.
The radial slewing mechanism is mainly composed of a rotating spring and a rotating chuck, and the radial 360-degree rotation adjustment of the tail end of the polishing machine is realized by pushing the rotating chuck to be meshed with a rotating clamping groove on the power output mechanism through the rotating spring, so that the radial angle adjustment of the tail end of the polishing machine is realized, and the radial slewing mechanism is suitable for complex operation environments.
The tail end angle adjusting device of the polishing head mechanism of the multi-degree-of-freedom polishing machine is provided with a range limiting device to limit the adjustable range of the tail end angle.
In the present invention, the intermediate helical gear is simultaneously engaged with the end helical gear to complete the transmission of power from the intermediate helical gear to the end helical gear. The meshing between the middle helical gear and the end helical gear is vertical to each other in the axial direction, so that the vertical steering function of the power is realized, and at this time, the power completes two vertical steering directions, namely, the axes of the three helical gears are vertical to each other two by two and present the same trend with the three directions of a rectangular coordinate system x, y and z, wherein the end helical gear is installed in the middle of an end helical gear rack, and the end helical gear rack is hinged on a shaft system where the middle helical gear is located, so that the end helical gear rack is not rigidly connected with the above-mentioned driving helical gear rack, and the angle adjusting mechanism in the multi-freedom polishing head mechanism is involved, and the detailed description is provided below. The tail end bevel gear in the tail end bevel gear rack and the shaft handle of the polishing disk form a tail end shaft system together, and finally the polishing disk is rapidly rotated.
In the angle adjusting mechanism, the limiting clamping grooves are positioned at the tail end and the right end of the middle bevel gear frame and are distributed on the tail end and the middle bevel gear frame in an array mode, and the center of the array is the center of the middle bevel gear shaft system. The limiting piston just needs to be matched with the limiting clamping groove to achieve the purpose of limiting the tail end angle, the matching mode is that the limiting piston is coaxial with the middle bevel gear frame, and the number and the shape of teeth, which are the same as those of the limiting clamping groove, of the limiting piston are distributed at one end, facing the limiting clamping groove.
After the limiting piston moves to the limiting clamping groove along the axial direction and is matched with the tail end of the limiting piston, the limiting piston cannot move inwards in the axial direction, the limiting function is achieved, the angle adjusting mechanism is limited, and the tail end angle adjustment of the polishing head mechanism of the multi-degree-of-freedom polishing machine cannot be achieved at the moment. The axial inward displacement of the limit piston is achieved by a limit switch cover coaxial with and adjacent to the piston. The limit switch cover is connected with the tail end of the middle bevel gear shaft through threads,
when the limit switch cover is screwed clockwise, the limit piston receives the axial extrusion force of the limit switch cover and moves inwards in the axial direction to finish the limit operation. The limiting spring which is coaxial with the limiting piston in the limiting piston is the key for releasing the limiting.
When the tail end of the polishing head mechanism of the multi-degree-of-freedom polishing machine is limited, the limiting spring is in a pressing state due to axial movement of the limiting piston, the limiting switch cover is rotated anticlockwise, the limiting piston starts to move outwards in the axial direction due to the pressure action of the limiting spring, when the limiting piston is completely separated from the limiting clamping groove, the tail end limiting state of the polishing head mechanism of the multi-degree-of-freedom polishing machine is relieved, and the tail end angle of the mechanism can be adjusted in a rotating mode.
Therefore, the mechanism increases two degrees of freedom for the working device at the tail end of the polishing machine by skillfully matching the bevel gears and assisting the angle adjusting mechanism, so that the tail end of the polishing machine can radially rotate by 360 degrees, and the front and back angle adjusting range is as high as 120 degrees, so that the mechanism can adapt to complex working environments, is more convenient and flexible, and improves the working efficiency.
It should be understood that this example is only for illustrating the present invention and is not intended to limit the scope of the present invention. Further, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
