CN203616526U - Angle-adjustable objective table used in microscopic hardness test - Google Patents

Abstract

The utility model provides an angle-adjustable microhardness testing stage, which belongs to the field of microscopic testing and mainly solves the problem of sample angle adjustment in the microhardness testing process. Its structure includes a rotary table, a gear adjustment mechanism and a worktable; the rotary table places the sample to be tested; the gear adjustment mechanism is composed of two gears, large and small, which mesh with each other. The large gear is fixedly connected to the rotary table, and the small gear is fixedly connected to the angle adjustment knob. , can realize the rotation of the rotary table; the table part can realize the linear adjustment in the XY direction through its own linear adjustment knob. The stage can be directly installed on the microhardness tester. During the test, the linear position of the sample in the XY direction can be adjusted through the linear adjustment knob on the workbench, and then the angle adjustment knob can be combined with the angle scale on the cover to make the test Rotate it like this to adjust its angle until it meets the requirements.

Description

A Microhardness Test Stage with Adjustable Angle

technical field

The utility model relates to an angle-adjustable microhardness testing stage, which belongs to the field of microscopic testing.

Background technique

The stage is a component that must be used in the field of microscopic testing. During the test, the sample is placed on the stage, and the position of the sample in the field of view is adjusted by adjusting the knob. Usually the stage consists of a base, a workbench and an adjustment knob. During the microhardness test, when testing the hardness layer, it is necessary to adjust the position of the sample in the field of view of the eyepiece so that the edge is parallel to the edge of the worktable, and then test the hardness value at different depths to obtain the thickness of the hardness layer.

In the existing published documents, such as CN102540441A "Microscope Stage" and CN1254098A "Microscope Stage", although the XY linear position of the sample can be adjusted, it is necessary to adjust the angle of the sample during the microhardness test. This process can only be operated manually at present, and the error in the microscopic view is very large.

Utility model content

The utility model designs a rotatable microhardness test stage for the current situation that the current microhardness test stage cannot realize the adjustment of the sample angle.

The technical scheme that the utility model solves its technical problem to take is:

The microhardness test stage includes a rotary table, a gear adjustment mechanism and a worktable. The sample to be tested is placed on the rotary table, the gear adjustment mechanism can realize the rotation of the rotary table, and the worktable part can realize XY through its own linear adjustment knob. Straight-line adjustment of direction.

The gear adjustment mechanism is composed of two gears, large and small, which mesh with each other. The large gear is fixedly connected to the rotary table, and the small gear is fixedly connected to the angle adjustment knob.

There is a pointer on the angle adjustment knob, and an angle scale is arranged around the cover plate mounting hole.

The utility model has the beneficial effects of simple structure, compact shape, convenient operation and good versatility, and can be used as a stage for ordinary microhardness testers and other microscopic testing instruments.

In the figure: 1 upper table, 2 screws, 3 cover plate, 4 rotary table, 5 lower table, 6 linear adjustment knob, 7 middle table, 8 angle adjustment knob, 9 support sleeve, 10 large gear, 11 small gear .

Detailed ways

As shown in Figure 1 and Figure 2, a microhardness test stage with adjustable angle, its structure includes 1 upper table, 2 screws, 3 cover plate, 4 rotating table, 5 lower table, 6 linear adjustment Knobs, 7 worktables, 8 angle adjustment knobs, 9 support sleeves, 10 large gears, 11 small gears. The rotary table places the sample to be tested, the gear adjustment mechanism can realize the rotation of the rotary table, and the worktable part can realize the linear adjustment in the XY direction through its own linear adjustment knob; the gear adjustment mechanism is composed of two gears, large and small, which mesh with each other. The gear is fixedly connected to the rotary table, and the pinion is fixedly connected to the angle adjustment knob; there is a pointer on the angle adjustment knob, and there is an angular scale around the mounting hole of the cover plate.

When in use, place the sample on the rotating table, observe it in the field of view of the eyepiece, adjust the linear position of the sample in the XY direction through the linear adjustment knob on the workbench, and then adjust the angle by combining the angular scale on the circumference of the cover mounting hole Knob to rotate the sample to adjust its angle until it meets the requirements.

Claims (1)
