Description

Technical Field

[0001] The utility model belongs to the technical field of microscope observation instruments, and more specifically, relates to an upright microscope specimen stage. Background Art

[0002] Metallographic inspection is a conventional method for steel quality inspection and defect analysis. During the metallographic inspection process, specimens need to be cut, inlaid, ground, polished, etc., and the surface conditions of the specimens are observed under a metallographic microscope. The microscope has relatively high requirements for the parallelism of the surface of the specimens to be detected. However, during the actual specimen preparation process, the specimens often show inclination, making it difficult or impossible to observe under the metallographic microscope, increasing the inspection difficulty.

[0003] In the prior art, the microscope specimen stage cannot automatically level the specimen. Usually, it is necessary to manually add shims under the specimen to adjust the specimen levelness. The operation process is complex, and a flattening device needs to be used in advance to flatten the specimen. The surface of the flattening device is in full contact with the surface of the specimen, which easily causes foreign matters to adhere to the detected surface of the specimen, reducing the surface finish of the specimen and affecting the observation effect. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an upright microscope specimen stage to solve the problem that the microscope specimen stage in the prior art cannot automatically level the specimen.

[0005] To achieve the above purpose, the utility model provides an upright microscope specimen stage, which includes:

[0006] A frame, the upper part of the frame is open, the inside has an installation space, and the bottom has an installation surface;

[0007] A planar limiting component, the planar limiting component is connected to the upper part of the frame, forms an observation opening, and the bottom can horizontally limit the observation surface of the sample;

[0008] An elastic component, the elastic component is installed on the installation surface and can apply an elastic force to the sample so that the observation surface of the sample contacts the bottom of the planar limiting component;

[0009] A stage for placing the sample;

[0010] A universal connection structure, the stage is connected to the elastic component through the universal connection structure, so that the stage can move in any direction.

[0011] The universal connection structure includes:

[0012] A groove body, the lower end of the groove body is connected to the elastic component, and the groove body has a ball groove;

[0013] Universal ball, the universal ball is matched with the ball groove in size and is arranged in the ball groove. The universal ball can move in any direction in the ball groove, and the universal ball is connected to the carrier.

[0014] The elastic component includes:

[0015] A cylindrical sleeve, a cylindrical rod and a spring. The lower end of the cylindrical sleeve is connected to the mounting surface. The cylindrical rod penetrates into the cylindrical sleeve and can slide telescopically in the cylindrical sleeve. The spring is sleeved outside the cylindrical sleeve and its upper part is connected to the upper part of the cylindrical rod.

[0016] The frame includes:

[0017] A base and at least a pair of fixing rods. At least a pair of the fixing rods are arranged on the upper surface of the base. The upper surface of the base forms a mounting surface. An installation space is formed between at least a pair of the fixing rods. The planar limiting component is connected to at least a pair of the fixing rods.

[0018] The planar limiting component includes at least two fixing claws. At least two of the fixing claws are respectively connected to at least a pair of the fixing rods. The bottoms of at least two of the fixing claws are located in the same plane.

[0019] There are multiple fixing rods. The number of the fixing claws is the same as the number of the fixing rods. Multiple fixing claws are respectively connected to multiple fixing rods. The bottoms of multiple fixing claws are located in the same plane.

[0020] The height of the cylindrical sleeve is less than the height of the cylindrical rod.

[0024] The present utility model provides an upright microscope sample stage, and its beneficial effects are as follows: The sample stage has a frame, and the bottom of the frame has a mounting surface; a planar limiting member is connected to the upper part of the frame, forming an observation opening, and the bottom can limit the plane; an elastic member is mounted on the mounting surface; the stage is connected to the elastic member through a universal connection structure. When in use, place the sample on the stage and press it downwards. After releasing the sample, the elastic member drives the stage and the sample to move upwards. When the detection surface of the sample contacts the bottom of the planar limiting member, the universal connection structure drives the stage to adjust the angle until the detection surface of the sample is in full contact with the bottom of the planar limiting member. At this time, the detection surface of the sample and the bottom of the planar limiting member are in the same plane. Then move the sample stage under the metallurgical microscope, and observe the sample through the observation opening of the planar limiting member.

[0034] The preferred embodiments of the present utility model will be described in more detail below. Although the preferred embodiments of the present utility model are described below, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present utility model more thorough and complete, and to fully convey the scope of the present utility model to those skilled in the art.

[0035] As Figure 1 shown, the present utility model provides an upright microscope sample stage, and the sample stage includes:

[0036] A frame 1, the upper part of the frame 1 is open, the inside has an installation space, and the bottom has an installation surface;

[0037] A planar limiting member, the planar limiting member 2 is connected to the upper part of the frame 1, forms an observation opening 22, and the bottom can horizontally limit the observation surface of the sample;

[0038] An elastic member 3, the elastic member 3 is installed on the installation surface, and can apply an elastic force to the sample so that the observation surface of the sample contacts the bottom of the planar limiting member 2;

[0039] A stage 4 for placing the sample;

[0040] A universal connection structure 5, the stage 4 is connected to the elastic member 3 through the universal connection structure 5, so that the stage 4 can move freely in any direction.

[0041] During specific implementation, place the sample on the stage 4 and press it downwards to compress the elastic member 3 downwards. After releasing the sample, the elastic member 3 applies an upward thrust to the stage 4 and drives the stage 4 and the sample to move upwards. When the detection surface of the sample contacts the bottom of the planar limiting member 2, the universal connection structure 5 drives the stage 4 to adjust the angle until the detection surface of the sample is in full contact with the bottom of the planar limiting member 2. At this time, the detection surface of the sample and the bottom of the planar limiting member 2 are in the same plane, and the elastic member 3 continues to apply an elastic force to keep the detection surface of the sample in this position, completing the automatic leveling of the sample. Move the sample stage under the metallurgical microscope, and observe the sample through the observation opening 22 of the planar limiting member 2. The bottom of the planar limiting member 2 can use multiple limiting points, multiple limiting lines, or use a limiting surface for limiting. The planar limiting member 2 can be of an integral structure or a split structure, and its specific form is not limited as long as it can limit the plane. The universal connection structure 5 can be implemented by various structures in the prior art.

[0042] Furthermore, the universal connection structure 5 includes:

[0043] A groove body 51, the lower end of the groove body 51 is connected to the elastic member 3, and the groove body 51 has a ball groove;

[0044] The universal ball 52, the universal ball 52 is matched with the size of the ball groove and is arranged in the ball groove. The universal ball 52 can rotate in any direction in the ball groove, and the universal ball 52 is connected to the carrier 4.

[0045] In this embodiment, the groove body 51 is of a cuboid structure, the ball groove is of a hemispherical structure, the size of the groove body 51 is larger than that of the ball groove, and the diameter of the universal ball 52 is slightly smaller than the diameter of the ball groove, so that the universal ball 52 can tilt in any direction in the ball groove and can be fixed in the ball groove.

[0046] Furthermore, the elastic member 3 includes:

[0047] A cylindrical sleeve 31, a cylindrical rod 32 and a spring 33. The lower end of the cylindrical sleeve 31 is connected to the mounting surface. The cylindrical rod 32 passes through the cylindrical sleeve 31 and can slide telescopically in the cylindrical sleeve 31. The spring 33 is sleeved outside the cylindrical sleeve 31 and its upper part is connected to the upper part of the cylindrical rod 32.

[0048] Specifically, when the cylindrical rod 32 is subjected to a downward pressure, it can slide downward in the cylindrical sleeve 31 and compress the spring 33. After the spring 33 is compressed, it can generate an upward restoring force, causing the cylindrical rod 32 to have an upward movement tendency.

[0049] Furthermore, the frame 1 includes:

[0050] A base 11 and at least a pair of fixing rods 12. At least a pair of the fixing rods 12 are arranged on the upper surface of the base 11. The upper surface of the base 11 forms a mounting surface. An installation space is formed between at least a pair of the fixing rods 12. The planar limiting member 2 is connected to at least a pair of the fixing rods 12.

[0051] In this embodiment, the base 11 is of a plate-like structure and is horizontally arranged. Two fixing rods 12 are vertically and oppositely arranged on the left and right sides of the base 11. The planar limiting member 2 is horizontally arranged above the two fixing rods 12. The two fixing rods 12 fix and support the planar limiting member 2.

[0052] Furthermore, the planar limiting member 2 includes at least two fixing claws 21. At least two of the fixing claws 21 are respectively connected to at least a pair of the fixing rods 12. The bottoms of at least two of the fixing claws 21 are located on the same plane.

[0053] In this embodiment, two fixing claws 21 are respectively arranged on the left and right sides. While ensuring the limiting accuracy, the structure of the device is simplified, which is suitable for observing samples with smaller sizes.

[0054] Furthermore, there are multiple fixing rods 12, the number of the fixing claws 21 is the same as the number of the fixing rods 12, the multiple fixing claws 21 are respectively connected to the multiple fixing rods 12, and the bottoms of the multiple fixing claws 21 are located in the same plane.

[0055] Specifically, when the sample size is large, using only two fixing claws 21 may result in low positioning accuracy. Using multiple fixing claws 21 can improve the stability and accuracy of sample positioning.

[0056] Furthermore, the height of the cylindrical sleeve 31 is smaller than the height of the cylindrical rod 32. Specifically, the height of the cylindrical sleeve 31 is smaller than the height of the cylindrical rod 32, which can increase the compression stroke of the spring 33 and improve its applicability.

[0057] Furthermore, the diameter of the cylindrical rod 32 is smaller than that of the cylindrical sleeve 31. Preferably, the diameter of the cylindrical rod 32 is slightly smaller than that of the cylindrical sleeve 31, so as to ensure the guiding accuracy of the cylindrical sleeve 31 to the cylindrical rod 32.

[0058] Furthermore, the height of the spring 33 is twice the height of the cylindrical sleeve 31. Specifically, this height setting ensures that the cylindrical rod 32 can always move vertically up and down in the cylindrical sleeve 31, and ensures that the cylindrical rod 32 does not separate from the cylindrical sleeve 31.

[0059] Furthermore, the frame 1 has a lifting structure that can adjust the height of the plane limiting component 2. Specifically, the height of the plane limiting component 2 can be adjusted according to the size of the sample, which has higher applicability.

[0060] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
