[0025] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0026] This utility model provides a stepless damping navigation tool, comprising:

[0027] The base is held in place, with one end used to connect to the dynamic adjustment head.

[0028] Navigation components, connected to the grip base;

[0029] The sleeve is inserted into the center hole of the holding base. The holding base also has a mounting hole, which is perpendicular to the axis of the center hole. A damping block is inserted into the mounting hole, and the damping block is in contact with the outer surface of the sleeve through a damping plate.

[0030] Specifically, in this navigation tool, the navigation component and the sleeve are mounted on the holding base. The navigation component is used to receive infrared light to monitor the position of the sleeve. The sleeve is shaped and limited by the wall of the central hole, which can ensure that the relative position of the sleeve and the navigation component is fixed and ensure accurate monitoring of the sleeve's position. The sleeve is in contact with the damping plate on the damping block, which can ensure that the sleeve will not loosen during the movement of the holding base.

[0031] Optionally, the navigation component includes a reflective base, which is connected to the holding base by screws. The reflective base has multiple fixing holes along its circumference, and the reflective ball is set in the fixing holes through a bottom cover.

[0032] Optionally, the navigation components are located on one or both sides of the grip base.

[0033] Specifically, the reflective ball and the sleeve in the navigation component are set on the same holding base and are fixedly connected to each other, thereby improving navigation accuracy and being unaffected by the robot system. In addition, the navigation component has reflective bases set on both sides of the holding base, and the two sets of reflective balls are arranged in parallel, which is conducive to multi-angle identification and observation. The sleeve and insertion tool are inserted from the center of the double-sided reflective ball, which is not limited to three-sided or multi-sided design.

[0034] Optionally, the fixing hole extends through both sides of the reflective base, with one end of the fixing hole having an opening larger than the reflective ball, and the other end of the fixing hole engaging with the outer surface of the reflective ball. One end of the fixing hole is detachably connected to the bottom cover.

[0035] Optionally, the spherical surface of the reflective sphere protrudes beyond the outer surface of the reflective base.

[0036] Specifically, the reflective ball is installed in the fixing hole through one end, and then the bottom cover supports the reflective ball. This ensures that the part of the reflective ball protruding from the reflective base is an arc surface, which is convenient for receiving infrared light. Multiple reflective balls are set on the surface of the reflective base. The orientation of the navigation component can be determined by three reflective balls, so that the position of the sleeve can be quickly determined.

[0037] Optionally, the holding base is provided with an installation direction indicator, which allows the sleeve to be installed quickly and accurately on the holding base.

[0038] Optionally, a pin is screwed onto the wall of the mounting hole, and the pin is connected to the damping block.

[0040] Specifically, after the sleeve is installed in the center hole, the damping block is inserted into the installation hole, and the damping plate is pressed against the outer surface of the sleeve. Since the damping plate is arc-shaped, it can be firmly pressed against the sleeve. When it is necessary to adjust the position of the sleeve in the center hole, it can be adjusted at will simply by forcefully inserting and pulling the sleeve.

[0041] Optionally, an observation hole is provided at the connection between the mounting hole and the center hole. This observation hole allows for confirmation of the fit between the damping plate and the sleeve, preventing the sleeve from accidentally slipping off.

[0042] Optionally, a snap-fit ​​block is provided at one end of the holding base to dynamically adjust the connection between the machine head and the robot system.

[0043] Specifically, the navigation tool can be quickly connected to the dynamic adjustment mechanism via a snap-fit ​​block, improving the installation efficiency of the navigation tool. Example
