Description
Technical Field
[0001] The utility model relates to the technical field of microscope stage adjustment, in particular to a microscope stage system. Background Art
[0002] The stage of the current microscope mainly achieves XYZ three-axis translation by electric or manual means. Conventional stages are connected by screws, and the verticality of the stage and the microscope needs to be adjusted during assembly, or high-precision tolerances need to be used.
[0003] The utility model with application number: CN201220429944.7 discloses an adjustable stage for a microscope, comprising a substrate arranged on a main body of the microscope, a Y-direction moving plate arranged on the substrate and slidingly matched with the substrate, an X-direction moving plate arranged on the Y-direction moving plate and slidingly matched with the Y-direction moving plate, and an adjusting plate arranged on the X-direction moving plate, an object to be measured is placed on the adjusting plate, and an adjusting device and a pre-tightening device are arranged between the X-direction moving plate and the adjusting plate. By setting the adjusting device and the pre-tightening device, the principle of three points not on the same straight line forming a plane is utilized, and the adjusting plate and the X-direction moving plate are pressed by the screw in the knob pre-tightening device. Since a steel ball is placed between the X-direction moving plate and the adjusting plate, a certain gap is left between the X-direction moving plate and the adjusting plate. Then, through the two screws in the knob adjusting device, the adjusting plate can be rotated in the X-axis and Y-axis directions with the steel ball as a fulcrum, thereby improving the adjustment accuracy of the stage.
[0004] In the prior art, the stage of the microscope may cause the verticality of the stage and the microscope tube to change during transportation. During use, the objective lens is not well protected. Once an operation error occurs, the lens cannot be effectively protected. Moreover, the conventional method is also very inconvenient to adjust, especially when screws are used for connection, which makes it difficult to quickly adjust the stage. Utility Model Content
[0005] The utility model aims to provide a microscope stage system, which has the advantage of convenient adjustment in actual use and can realize the precise adjustment of the horizontality of a stage plate in the stage.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0007] A microscope stage system, comprising a stage plate for mounting on a mounting plate in a microscope translation stage assembly, wherein the stage plate is provided with three mounting holes, the three mounting holes are distributed in an L shape, and an adjustment assembly is respectively mounted in the three mounting holes;
[0008] A first positioning hole, a second positioning hole and a third positioning hole are provided on the mounting plate of the microscope translation stage assembly, and the first, second and third positioning holes correspond to the three adjustment assemblies one by one respectively;
[0009] The adjustment component includes a ring and a screw with a steel ball movably arranged at the bottom. The ring is used to be fixedly installed in the mounting hole on the stage plate. The screw is installed in the ring through threads, and the steel balls in the screws in the three adjustment components are respectively in contact with the first, second and third positioning holes on the mounting plate; the stage plate and the mounting plate are adsorbed together by a magnetic suction component.
[0010] Among them, the first positioning hole is a stepped hole, and the steel ball in the screw contacts the bottom surface of the stepped hole, so that the screw can move on the XY plane on the bottom surface of the stepped hole.
[0011] Furthermore, the second positioning hole includes a circular hole and a conical groove connected to the bottom of the circular hole, and the steel ball in the screw contacts the side of the conical groove, so that the steel ball can only rotate around the center line of the conical groove.
[0012] Wherein, the third positioning hole is a V-shaped groove.
[0013] Furthermore, the third positioning hole includes a first circular hole and side grooves arranged on both sides of the first circular hole and connected to the first circular hole, and round rods are arranged in the side grooves. The round rods in the grooves on both sides are in contact with the steel balls in the screw, so that a V-shaped slide is formed between the round rods so that the steel balls in the screw move along the axis direction of the round rods.
[0014] Among them, the round rod is a steel rod.
[0015] Furthermore, the magnetic attraction assembly includes a first magnet and a second magnet, the first magnet is mounted on the stage plate, and the second magnet is mounted on the mounting plate.
[0016] The stage plate and the mounting plate are respectively provided with a first mounting hole and a second mounting hole for mounting the first magnet and the second magnet, and the positions of the first magnet and the second magnet correspond to each other.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] In actual use, the utility model realizes the adjustment of the horizontality of the loading platform plate by setting up three groups of adjustment components. Since the adjustment component includes a ring and a screw with a steel ball movably provided at the bottom, it is only necessary to rotate the screw for adjustment so that the loading platform plate can rotate at the position of the steel ball. The loading platform plate can be quickly adjusted by adjusting the position of the screw. Moreover, since the loading platform plate and the mounting plate are connected after being adsorbed by the magnetic suction component, when the screw is rotated to adjust the horizontality of the loading platform plate, it is ensured that the loading platform plate can be slightly displaced, thereby realizing the adjustment of the loading platform plate.
