DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 3 A digital display rotary fine-tuning device comprises a digital display differential mechanism 1; a connecting seat 2 is installed at the left end of the digital display differential mechanism 1, a positioning block 3 is embedded in the memory of the connecting seat 2, a fine-tuning rotary table 4 is fixed to the rear end of the positioning block 3, a convex rod is provided at the bottom of the fine-tuning rotary table 4, and the convex rod is plugged into the inner side of the positioning mechanism 5, the digital display differential mechanism 1 comprises a reading head 11, a control button 12, a display screen 13, a rotating micrometer screw 14, a measuring rod 15, and a locking block 16, the control buttons 12 are evenly distributed at the top front end of the reading head 11, and the reading head 11 A display screen 13 is embedded in the top, and a rotating micrometer screw 14 is installed at the right end of the reading head 11, and the rotating micrometer screw 14 is movably connected to the inner side of the right end of the reading head 11, and the rotating micrometer screw 14 is connected to the right end of a measuring rod 15, and the measuring rod 15 slides with the inner side of the reading head 11, and a locking block 16 is fixed to the left end of the measuring rod 15, and the measuring rod 15 passes through the middle of the connecting seat 2, and the connecting seat 2 moves synchronously with the measuring rod 15, and the right end surface of the rotating micrometer screw 14 is circumferentially distributed with anti-slip grooves to facilitate the rotation of the rotating micrometer screw 14.

[0031] In some embodiments, the reading head 11 is a common electronic display. When the rotating micrometer screw 14 rotates in the reading head 11, the rotating micrometer screw 14 advances or retreats along the direction of the rotation axis by a pitch. Therefore, the small distance moved along the axis direction can be represented by the reading on the circumference. The sensor in the electronic display converts the rotational motion into an electrical signal. After signal conversion, amplification processing and nonlinear correction, the display screen 13 is driven to display the measurement result. The forward movement of the rotating micrometer screw 14 drives the measuring rod 15 to move synchronously, so that the measuring rod 15 drives the connecting seat 2 to move to a corresponding position, and then the position of the fine-tuning rotating table 4 can be changed to achieve fine-tuning of the fine-tuning rotating table 4. The fine-tuning rotating table 4 is an ordinary fine-tuning rotating table, also known as a precision rotating table or a fine-tuning rotating table, which is a device that can adjust a small angle manually or electrically. It is mainly used in the fields of optics, precision machinery, semiconductor manufacturing, etc. to achieve high-precision angle positioning, rotation and fine-tuning. Objects to be detected can be placed on it, and the rotation of the objects to be detected is achieved through the fine-tuning rotating table 4.

[0032] See also Figure 4-Figure 7 A digital display rotary fine-tuning device, the positioning mechanism 5 includes a placement table 51, a positioning hole 52, and a clamping mechanism 53. The placement table 51 is fixed to the rear end of the positioning block 3. A positioning hole 52 is provided in the middle of the top of the placement table 51. The clamping mechanism 53 is installed inside the placement table 51. The clamping mechanism 53 includes a pressing plate 531, a compression spring 1 532, a compression spring 2 533, a support seat 534, a clamping block 535, and a groove 536. The pressing plate 531 runs through the middle of the placement table 51, and the pressing plate 531 is slidably matched with the inner side of the placement table 51. A groove 536 is provided in the middle of the pressing plate 531, and the middle of the groove 536 A clamping block 535 runs through the clamping block 535, the bottom of which is fixed to the support seat 534, the compression spring 1 532 and the compression spring 2 533 are symmetrically arranged, and the tops of the compression spring 1 532 and the compression spring 2 533 are fixedly connected to the pressure plate 531, and the bottoms of the compression spring 1 532 and the compression spring 2 533 are fixed to the inside of the placement table 51, and the clamping blocks 535 are arranged in multiple groups, and the clamping blocks 535 are distributed circumferentially along the top of the support seat 534, the lower end of the clamping block 535 is inclined, and the diameter of the clamping block 535 gradually increases from top to bottom, and the inner wall of the groove 536 is inclined, and the inclination angle is consistent with the inclination angle of the lower end of the clamping block 535.

[0033] In some embodiments, a convex rod is embedded in the inner side of the clamping block 535, and the compression spring 1 532 and the compression spring 2 533 are ordinary springs. A spring is a mechanical part that works by using elasticity. Parts made of elastic materials deform under the action of external forces and return to their original state after the external force is removed. It is also called a "spring". It is generally made of spring steel. By pressing the pressing plate 531, the pressing plate 531 moves downward, and the compression spring 1 532 and the compression spring 2 533 are deformed and contracted. When the pressure on the pressing plate 531 is removed, the pressing plate 531 is driven to reset by the compression spring 1 532 and the compression spring 2 533.

[0034] In summary, when in use, first press the pressing plate 531 downward to release the pressing plate 5631 from the upward embrace of the clamping block 535, so that the clamping block 535 opens to the surroundings of the support seat 534, and then align the bottom protruding rod of the fine-tuning rotating table 4 with the middle of the clamping block 535 to be embedded, and at the same time, the positioning block 3 is embedded in the inner side of the connecting seat 2;

[0035] Then, the pressure on the pressure plate 531 is released, and the pressure plate 531 is driven to move upward by the compression springs 1 532 and 2 533, so that the groove 536 of the pressure plate 531 gathers the clamping block 535 toward the middle, so that the clamping block 535 embraces and clamps the protruding rod, thereby realizing the rapid clamping and positioning of the fine-tuning rotating table 4 and increasing the efficiency of assembly.
