Description

Technical Field

[0001] The utility model relates to the technical field of index plates, and particularly relates to a new type of index plate. Background Technique

[0002] An index plate is a machine tool accessory that clamps a workpiece on a chuck or between two center points and rotates, indexes, and positions it. According to its transmission and indexing forms, it can be divided into worm gear index plates, dial index plates, hole index plates, groove index plates, end tooth index plates, and other index plates (including inductive index plates and grating index plates). According to its functions, it can be divided into universal index plates, semi-universal index plates, and equal division index plates. According to its structural form, there are also vertical and horizontal index plates, tilting index plates, and cantilever index plates. As a general-purpose machine tool accessory, the structure of the index plate mainly consists of a clamping part, an indexing and positioning part, and a transmission part. The index plate is mainly used in milling machines, and is also commonly used in drilling machines and surface grinding machines. It can also be placed on a platform for fitters to mark lines. There are mainly two types of index plates: universal index heads and optical index heads.

[0003] The patent document with the application number CN201922417871.4 discloses an index plate device, which includes a power mechanism, an index plate, a fixed seat, and a speed detection mechanism. The power mechanism includes a linkage shaft; the index plate is connected to the linkage shaft; the fixed seat is installed below the index plate; the speed detection mechanism includes an inductor and an inductive part that matches the inductor. The inductor is installed on one side of the fixed seat facing the index plate, and the inductive part is installed on the index plate and is located above the inductor. The inductor is installed on the fixed seat and does not move during use. The inductive part rotates with the rotation of the index plate, and the position of the inductive part is fixed. The distance between the inductive part and the center of the index plate is determined, and its moving arc length can be calculated. The rotation speed of the index plate can be calculated through the time when the inductor senses the inductive part twice and the moving arc length of the inductive part, providing a data basis for accurately controlling the operation of the index plate, which is beneficial to improving production quality and production efficiency. Based on the retrieval of the above patent and the combination with the existing index plates in the prior art, it is found that there are some problems in the existing index plate devices during use. Due to the structural design of the index plate device, continuous friction is borne between the index plate body and the lower-layer parts. During the rotation process, relatively large frictional forces may be generated, resulting in unstable operation of the equipment. Especially after long-term use, severe wear occurs, which also leads to a decrease in indexing accuracy. Content of the Utility Model

[0025] Please refer to Figures 1 to 8, in the embodiment of the present utility model, a new type of indexing plate includes a mounting plate 1. A regulation seat 2 is fixedly installed at the upper end of the mounting plate 1. A turntable body 3 is arranged at the upper end of the regulation seat 2. A lubrication mechanism 4 and a limiting mechanism 5 are arranged between the turntable body 3 and the regulation seat 2. The lubrication mechanism 4 includes a fixed bearing ring 401, a bearing rotating ring 402, a ball rotating ring 403, ball bodies 404, a liquid injection pipe 405 and a lubricating liquid tank 406. The fixed bearing ring 401 is fixedly installed at the upper end of the regulation seat 2. The ball rotating ring 403 is arranged inside the fixed bearing ring 401. The bearing rotating ring 402 is arranged inside the ball rotating ring 403. The ball rotating ring 403 is located between the fixed bearing ring 401 and the ball rotating ring 403. The liquid injection pipe 405 is fixedly installed on the regulation seat 2. The liquid injection pipe 405 is inserted into the outside of the fixed bearing ring 401 inwardly. The lubricating liquid tank 406 is arranged inside the liquid injection pipe 405. The ball bodies 404 are installed on the ball rotating ring 403. Multiple groups of ball bodies 404 are distributed and installed on the ball rotating ring 403. The lubrication mechanism 4 further includes a connecting plug rod 407 and a connecting slot 408. The connecting plug rod 407 is fixedly installed at the lower end of the turntable body 3. Multiple connecting plug rods 407 are fixedly installed at the lower end of the turntable body 3.

The connecting slot 408 and the connecting plug rod 407 are in a plugging relationship;

[0026] The cooperation between the bearing rotating ring 402 and the turntable body 3 effectively reduces the friction force and improves the rotation stability of the turntable body 3. The ball rotating ring 403 and the ball bodies 404 are used in combination, which greatly reduces the friction between the bearing rotating ring 402 and the fixed bearing ring 401. At the same time, the spherical design of the ball rotating ring 403 and the ball bodies 404 enables the turntable body 3 to rotate flexibly during the rotation process, improves the rotation efficiency of the equipment, thereby reducing the friction force and improving the rotation stability of the turntable body 3; the liquid injection pipe 405 enables the lubricating oil to be conveniently injected into the area of the ball rotating ring 403 and the ball bodies 404, ensuring the long-term stable operation of the equipment; the limiting mechanism 5 includes a threaded groove 501, a limiting screw 502 and a rotating ring body 503.

The limiting screw 502 is threadedly connected with the regulation seat 2. The end of the limiting screw 502 away from the regulation seat 2 is fixedly installed with the rotating ring body 503.

[0027] The working principle of the present utility model is as follows: This dividing disc is additionally provided with a lubricating mechanism 4 and a limiting mechanism 5. When using this dividing disc, the regulating base 2 can be enabled to rotate the turntable body 3. During the rotation of the turntable body 3, the bearing ring 402 in the lubricating mechanism 4 rotates synchronously with the turntable body 3. A ball ring 403 and ball bodies 404 are arranged between the bearing ring 402 and the fixed bearing ring 401, thereby providing a stable rotation effect. After long-term use, lubricating oil can be injected into the area of the ball ring 403 and ball bodies 404 through the liquid injection pipe 405 and the lubricating liquid tank 406 to lubricate the bearing structure and ensure the stability of the rotation of the turntable body 3. In summary, the lubricating mechanism 4 uses a bearing structure to support the regulating base 2 and the turntable body 3. The bearing structure can effectively reduce the friction during rotation, improve the stability of the equipment. At the same time, the rotation accuracy of the bearing is relatively high, which can improve the positioning accuracy of the dividing disc device. Moreover, a lubricating oil adding area is also provided in the lubricating mechanism 4, and lubricating oil can be quickly added to achieve the lubrication effect. The limiting mechanism 5 adopts the method of bolt fastening to cooperate with the stability of the bearing structure in the lubricating mechanism 4.
