[0014] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0015] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0016] like Figures 1 to 3 As shown, a metallographic sample cutting device for aluminum material includes a base plate 100, on which an inclined swing arm 200 capable of swinging up and down is provided, a sample fixture 300 is provided at the upper end of the swing arm, and a cutting saw blade 400 driven by a motor is provided below the sample fixture 300, the cutting saw blade is fixed on the main shaft of the motor, and different rotation speeds can be controlled; a threaded hole penetrating the upper and lower sides is provided in the middle of the swing arm 200, and a limit screw 500 is provided in the threaded hole to support the base plate after the swing arm swings down to limit the swing arm swing angle. The device can cut samples from different positions and angles, and the sample preparation efficiency is high and stable and reliable; the limit screw 500 is used as a stroke adjustment switch, equivalent to a limit switch, for controlling the cutting depth of the sample. When the lower end of the limit screw is against the base plate, the swing arm cannot continue to swing.

[0017] In this embodiment, a fixing plate 110 is fixedly connected to the bottom plate 100, and the swing arm 200 is hinged to the fixing plate near the lower end; a sleeve rod 210 for mounting weights is provided on the upper side of the upper end and the upper side of the lower end of the swing arm. The swing arm is made of stainless steel, and the sleeve rod is used to place weights of different weights. The weights can form different loading weights on the sleeve rod, and different weights form different loading forces and torques. The weights are used to adjust the cutting force of the sample during cutting.

[0018] In this embodiment, a threaded hole is provided on the fixing plate 110, a connecting shaft 220 is passed through the threaded hole, the swing arm 200 is rotatably connected to the connecting shaft 220, the connecting shaft is provided with an external thread section threadedly matched with the threaded hole on the fixing plate, and one end of the connecting shaft is connected to a rotating wheel 221. The forward and backward movement of the rocker arm is controlled by the connecting shaft, and when the rotating wheel rotates forward and reversely, the connecting shaft can be extended and retracted relative to the fixing plate due to the threaded connection with the fixing plate, thereby driving the rocker arm to move forward and backward.

[0019] In this embodiment, the sample fixture 300 includes an upper clamping plate 310 and a lower clamping plate 320, and the upper and lower clamping plates are connected together by two bolts 330. The upper side of the upper clamping plate is fixedly connected with a connecting block 340, and the connecting block is connected to one side of the swing arm through an adjusting bolt 350. When the adjusting bolt 350 is loosened, the entire sample fixture 300 can be rotated around the adjusting bolt 350, thereby adjusting the cutting position and cutting angle of the sample, so as to achieve cutting of samples from different positions and angles, and the sample preparation efficiency is high and stable and reliable. The sample fixture is in a well shape, and the upper and lower clamping plates are connected by two bolts. The middle of the two upper and lower clamping plates can be made into different shapes for clamping samples of different shapes. The two upper and lower clamping plates have rubber pads close to the sample side for protecting the sample.

[0020] The following example illustrates the use of the aluminum metallographic sample cutting device. For example, if you want to take a block sample of a certain size from the center of a cylindrical sample:

[0021] (1) Select the upper and lower clamps with arc grooves in the middle, the sample fixture and clamp the sample;

[0022] (2) The front and rear positions of the rocker arm are adjusted by rotating the wheel, and the length of the sample cut is close to the cutting blade;

[0023] (3) Adjust the limiting screw in the middle of the rocker arm to ensure that the entire cylindrical sample can be cut;

[0024] (4) Place weights of different weights to control the cutting force;

[0025] (5) Start the motor and start cutting;

[0026] (6) Similarly, remove the excess part at the edge of the cylindrical sample to obtain a block sample in the center.

Any technician in the field should understand that the preferred numerical range is only a numerical value with a more obvious technical effect or representative value among many feasible numerical values. Since there are too many numerical values ​​to be exhaustive, the utility model discloses only some numerical values ​​to illustrate the technical solution of the utility model, and the numerical values ​​listed above should not constitute a limitation on the scope of protection of the utility model.

[0028] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).

[0029] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.
