Description

Technical Field

[0001] This utility model belongs to the field of calibration equipment technology, and in particular relates to a calibration device for an optical diopter tube. Background Technology

[0002] In the field of optical instruments, the optical diopter tube is an important component, widely used in various optical devices such as telescopes, microscopes, and sights. Its function is to help users adjust the relative position between the eyepiece and the objective lens to accommodate the differences in vision of different users, so that the observer can obtain a clear image. However, during the manufacturing process of the optical diopter tube, due to the influence of various factors, such as machining accuracy errors and assembly process deviations, the actual diopter of the diopter tube may deviate from the design requirements, so it is necessary to correct it.

[0003] However, existing optical diopter tube calibration equipment is not convenient for precisely adjusting the optical diopter tube to the appropriate angle during use, resulting in angular deviations during measurement and calibration, which in turn affects the final calibration accuracy, makes it difficult to achieve the ideal calibration effect, and leads to a decrease in the imaging quality of optical instruments. Utility Model Content

[0004] The purpose of this invention is to provide a calibration device for optical diopter tubes. By setting an adjustment mechanism, it solves the problem that existing optical diopter tube calibration devices are difficult to make the optical axis of the tube coincide with the optical axis of the target being measured during use, resulting in angular deviation during measurement and ultimately large errors in the measurement data, making the measurement results larger or smaller than the actual values.

[0005] The technical solution of this utility model is as follows:

[0006] This utility model is a correction device for optical diopter tubes, including a rectangular platform, on which an adjustment mechanism and a lifting mechanism are provided;

[0007] A tube fixing plate runs through the rectangular platform, and the tube fixing plate is rotatably connected to the rectangular platform. An optical vision tube is provided on the top of the tube fixing plate. The adjustment mechanism includes two rectangular support plates fixedly connected to the bottom of the rectangular platform. A bidirectional threaded rod is rotatably connected between the two rectangular support plates. A motor is fixedly connected to the front side of the rectangular support plate located on the front side. The output shaft of the motor is fixedly connected to the bidirectional threaded rod through a coupling. The lifting mechanism includes several hollow support legs arranged below the rectangular platform. Several connecting rods are fixedly connected to the bottom of the rectangular platform. The bottom of the connecting rods extends into the hollow support legs. Two L-shaped support plates are fixedly connected to the outer walls of the hollow support legs.

[0008] Two movable plates are threadedly connected to the outer wall of the bidirectional threaded rod. A slide rod is fixedly connected to one side of each movable plate that is close to each other. The rear side of the slide rod on the left side passes through the movable plate on the rear side, and the slide rod on the left side is slidably connected to the movable plate on the rear side. The front side of the slide rod on the right side passes through the movable plate on the front side, and the slide rod on the right side is slidably connected to the movable plate on the front side.

[0009] A connecting block is fixedly connected to the outer wall of each of the two sliding rods, and a connecting rod is hinged to the bottom of each of the two connecting blocks. The top of each of the two connecting rods is hinged to the tube fixing plate.

[0010] A rectangular plate is fixedly connected to the top of the two L-shaped support plates, and a motor is fixedly connected to the bottom of the rectangular plate.

[0011] The output shaft of the second motor is fixedly connected to a worm gear via a coupling. The top of the worm gear passes through a rectangular plate, and the worm gear is rotatably connected to the rectangular plate.

[0012] The top of the rectangular plate is fixedly connected to several U-shaped support blocks, and two rotating shafts pass through the several U-shaped support blocks. The two rotating shafts are rotatably connected to the several U-shaped support blocks.

[0013] Both of the two rotating shafts are fixedly connected to the outer walls of the shafts, and both of the worm gears mesh with the worm. Both of the worm gears are fixedly connected to the outer walls of the shafts.

[0014] The bottom of each of the connecting rods 2 is provided with a groove, and a sliding rod 2 is fixedly connected to the inner wall of each of the grooves. The outer wall of each sliding rod 2 extends into each of the connecting rods 3, and the sliding rods 2 are slidably connected to each of the connecting rods 3.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting an adjustment mechanism, when the angle of the optical diopter tube needs to be adjusted, motor one can be started. Motor one will drive the bidirectional threaded rod to rotate. At this time, the two connecting blocks will move closer or further apart under the interaction of the two moving plates and the two sliding rods. During this process, the tube fixing plate will shift in angle under the connection of the connecting rod, thereby completing the adjustment of the angle of the optical diopter tube. This ensures the stability of the connecting blocks during the movement, reduces shaking and offset, and makes the tube fixing plate more stable when adjusting the angle. This ensures that the optical diopter tube can accurately reach the set angle position, improving the accuracy and repeatability of angle adjustment.

[0017] 2. By setting up a lifting mechanism, after the angle adjustment is completed, motor two can be started according to the height of the optical diopter tube to be calibrated. Motor two will drive the rotating shaft on the U-shaped support block to rotate through the worm gear and worm wheel. When the rotating shaft rotates, connecting rod three will swing around the rotating shaft and cooperate with sliding rod two in the groove. Through connecting rod two, the optical diopter tube on the rectangular platform and tube fixing plate will be moved upward, thus completing the height adjustment of the optical diopter tube. This allows for convenient height adjustment according to actual measurement needs, enabling the optical diopter tube to be accurately positioned in space to the optimal measurement position. This provides strong support for achieving more complex and comprehensive optical measurement tasks and enhances the flexibility and multifunctionality of the equipment.
