Description

Technical Field

[0001] This utility model relates to control equipment for optical elements, and more particularly to a thin, large-area rotary table that can replace a breadboard. Background Technology

[0002] A rotary table is a motion control device used to adjust the rotational position of optical components. A breadboard is a flat plate covered with standard threaded holes, facilitating the installation of various optical components to form various optical systems. It can be easily fixed to optical platforms and other platforms. The thickness is typically 12.7mm, the thread pitch is generally 25mm, and the screw holes are mostly M6 screw holes. However, existing rotary tables are relatively thick, their area is not large enough, they are not the same height as the breadboard, and their area is not as large as a typical breadboard. Their structure is not compact enough, and they are not flexible enough under heavy loads. Furthermore, the screw hole arrangement and installation method of existing rotary tables are inconsistent with those of breadboards. Therefore, it is necessary to design a rotary table that can replace a breadboard. Utility Model Content

[0003] Purpose of the utility model: The purpose of this utility model is to provide a thin, large-area rotating table that can replace a breadboard.

[0004] Technical Solution: The thin, large-area rotary table of this utility model includes a rotating plate, a replaceable core plate, multiple core plate fixing screws, a fixed plate, an axial locking plate, a thrust roller bearing, multiple locking plate fixing screws, and multiple rubber-headed screws. From top to bottom, the components are a replaceable core plate, a rotating plate, a fixed plate, and an axial locking plate. The replaceable core plate is fixed on the rotating plate, and the rotating plate is mounted on the fixed plate with a small clearance fit. The rotating plate rotates relative to the fixed plate. The axial locking plate is located on the lower side of the fixed plate and is fixed to the lower side of the rotating plate. It rotates together with the replaceable core plate and the rotating plate. After rotating to the required angle, the rotating plate is locked in position by rubber-headed screws located on the side of the fixed plate. The rubber-headed screws point axially towards the center of the rotary table.

[0005] Furthermore, a thrust roller bearing is provided in the gap between the rotating plate and the fixed plate.

[0006] Furthermore, the replaceable core board is fixed to the rotating plate by core board fixing screws.

[0007] Furthermore, the axial locking plate is fixed to the underside of the rotating plate by locking plate fixing screws.

[0008] Furthermore, the rotating plate and the fixed plate are provided with scales, and the two zero marks are aligned at the initial moment.

[0009] Furthermore, the rotating plate is hollow in the middle, and a replaceable core plate is fixed on the upper side of the groove, while the axial locking plate is fixed on the lower side of the groove.

[0010] Furthermore, the fixing plate and the axial locking plate are hollow in the middle.

[0011] Beneficial effects: Compared with the prior art, this utility model has the following advantages: The rotary table of this utility model can replace the breadboard and has a rotation function. The symmetrical double-headed screws pointing axially towards the center of the rotary table ensure that the position of the rotary table does not change when locked, and increases the reliability of the fixation. The ingenious cross-sectional arrangement and the misalignment of the planar structure (axial locking plate, thrust roller bearing, replaceable core plate, and misaligned arrangement of screw holes) increase rigidity and reduce height. It not only allows the insertion of thrust bearings to ensure the requirements of heavy load, but also avoids the position of the screw holes in the breadboard. Attached Figure Description

[0017] Figure 6 This is an exploded view of the present invention from bottom to top. Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 , 2 As shown, this utility model includes a rotating plate 1, a replaceable core plate 2, multiple core plate fixing screws 3, a fixing plate 4, an axial locking plate 5, a thrust roller bearing 6, multiple locking plate fixing screws 7, and two rubber-headed screws 8.

[0020] like Figure 5 , 6 The exploded view shown is of this utility model. From top to bottom, the components are a replaceable core plate 2, a rotating plate 1, a fixing plate 4, and an axial locking plate 5.

[0021] The replaceable core plate 2 is fixed on the rotating plate 1, which is mounted on the fixed plate 4 with a certain gap between them. The rotating plate 1 rotates relative to the fixed plate 4. The lower side of the fixed plate 4 is an axial locking plate 5, which is fixed to the lower side of the rotating plate 1 and rotates together with the replaceable core plate 2 and the rotating plate 1. After rotating to the desired angle, the rotating plate 1 is locked in place by rubber-headed screws 8 located on the side of the fixed plate 4. The rubber-headed screws 8 axially point towards the center of the turntable. Figure 4 As shown.

[0022] A thrust roller bearing 6 is provided in the gap between the rotating plate 1 and the fixed plate 4. The replaceable core plate 2 is fixed to the rotating plate 1 by core plate fixing screws 3, as shown below. Figure 3 As shown, the axial locking plate 5 is fixed to the lower side of the rotating plate 1 by locking plate fixing screws 7. The rotating plate 1 and the fixing plate 4 are provided with scales. Initially, the two zero scale lines are aligned. The middle of the rotating plate 1 is hollow. The replaceable core plate 2 is fixed to the upper side of the groove, and the axial locking plate 5 is fixed to the lower side of the groove. The middle of the fixing plate 4 and the axial locking plate 5 is hollow.

[0023] Existing rotary tables cannot replace breadboards. This invention is a rotating breadboard with a replaceable center plate and can define various mounting hole positions.

[0024] The working principle of this utility model is as follows: The replaceable core plate 2 is fixed on the rotating plate 1. The rotating plate 1 can be pushed by hand and rotated to the required angle. Then, the position is locked by the rubber head screw 8 (the rubber head screw points axially to the center of the turntable to ensure that the turntable does not rotate when locked).

[0025] This utility model's rotary table can replace a breadboard and has a rotation function. The symmetrical double-headed screws axially point towards the center of the rotary table, ensuring that the position of the rotary table does not change when locked and increasing the reliability of the fixation. The ingenious cross-sectional arrangement and the misaligned use of the planar structure (axial locking plate, thrust roller bearing, replaceable core plate, and misaligned screw hole arrangement) increase rigidity and reduce height. This not only allows for the inclusion of a thrust bearing to meet heavy load requirements but also avoids the location of the screw holes on the breadboard.
