[0002] In the fields of materials analysis, industrial testing and scientific research experiments, cutting equipment is widely used in sample preparation. When existing cutting equipment is used for cutting operations, in order to ensure operational safety and cutting accuracy, the sample to be cut must be firmly fixed on the cutting platform to prevent the sample from shifting, vibrating or accidentally splashing under the action of cutting force, which could cause equipment damage, sample scrapping or even personal safety accidents.

[0003] Currently, conventional sample fixing methods mainly rely on mechanical clamps, such as flat-jaw vises and pressure plate bolt structures. These fixing devices have good applicability and stability for regularly shaped plates. However, when faced with irregularly shaped or irregularly contoured columns, they often cannot achieve a good fastening effect. As a result, different auxiliary fixing clamps need to be prepared for different irregularly shaped columns, which increases the time and economic costs of using the equipment. Utility Model Content

The first arc-shaped gripper 340 and the second arc-shaped gripper 440 are suitable for cooperating to clamp and fix irregular cylindrical samples (not shown in the figure).

[0029] The beneficial effect of the cutting fixture 10 provided in this application is that, compared with the prior art, the cutting fixture 10 is provided with a first clamping unit 300 and a second clamping unit 400, which cooperate to form a clamping and fixing area. In this way, the relative distance between the first movable arm group 310 and the second movable arm group 410 can be adaptively adjusted according to the specific size of the irregular cylindrical sample to adjust the size of the clamping and fixing area accordingly. Then, based on the specific contour of the irregular cylindrical sample, the first adjusting shaft 320, the first arc-shaped jaw 340, the second adjusting shaft 420, and the second arc-shaped jaw 440 are rotated respectively to... The first arc-shaped gripper 340 and the second arc-shaped gripper 440 make good contact with the irregular cylindrical sample. Finally, the first adjusting screw 330 and the second adjusting screw 430 are rotated respectively to make the first arc-shaped gripper 340 and the second arc-shaped gripper 440 cooperate to squeeze the irregular cylindrical sample, thereby achieving a fastening effect on the irregular cylindrical sample. It can be seen that the above-mentioned cutting fixture 10 can adapt to the fastening and fixing of irregular main body samples of different sizes and contours, without the need to prepare different auxiliary fixing fixtures for different irregular cylindrical samples, thus reducing the time and economic costs of using the cutting equipment.

[0030] Please refer to the following: Figure 4 and Figure 5 In this embodiment, the first movable arm assembly 310 and the second movable arm assembly 410 are respectively movably sleeved on the adjusting guide rail 200 along the horizontal transmission direction of the adjusting guide rail 200. The first movable arm assembly 310 is threaded with a plurality of first fastening bolts 390, which are adapted to pass through the first movable arm assembly 310 to cooperate and fasten against the adjusting guide rail 200, thereby locking or unlocking the first movable arm assembly 310. The second movable arm assembly 410 is threaded with a plurality of second fastening bolts 490, which are adapted to pass through the second movable arm assembly 410 to fasten against the adjusting guide rail 200, thereby locking or unlocking the second movable arm assembly 410. In this way, based on the specific size of different irregular cylindrical samples, the relative distance between the first movable arm assembly 310 and the second movable arm assembly 410 can be adaptively adjusted along the horizontal direction to lock the first movable arm assembly 310 and the second movable arm assembly 410 respectively.

[0031] Please refer to the following: Figure 3 and Figure 4In this embodiment, the first clamping unit 300 further includes two first pivot nuts (not shown in the figure) and two first pivot bolts 350. The first adjusting pivot 320 is horizontally arranged. The two first pivot nuts are coaxially fixed at opposite ends inside the first adjusting pivot 320. The two first pivot bolts 350 pass through the first movable arm assembly 310, the first adjusting pivot 320, and the corresponding first pivot nuts in sequence, so as to be rotatably connected to the first movable arm assembly 310 and threadedly connected to the corresponding first pivot nuts. The end of each first pivot bolt 350 facing away from the first pivot nut is also provided for abutting against the first movable arm assembly 310 facing away from the first adjusting pivot 320. The first abutment part on side 0 (not shown in the figure) is such that by reverse-tightening the two first pivot bolts 350, the first abutment parts of the two first pivot bolts 350 are separated from the first movable arm assembly 310, thereby unlocking the first adjusting pivot 320 and allowing the first adjusting pivot 320 to rotate. By forward-tightening the two first pivot bolts 350, the first abutment parts of the two first pivot bolts 350 are respectively abutted against the first movable arm assembly 310, thereby locking the first adjusting pivot 320 and preventing the first adjusting pivot 320 from rotating. In this way, the tilt angle of the first adjusting screw 330 is adjusted adaptively by the first adjusting pivot 320 and the tilt angle is kept constant.

[0032] Please refer to the following: Figure 3 and Figure 5 In this embodiment, the second clamping unit 400 further includes two second pivot nuts (not shown in the figure) and two second pivot bolts 450. The second adjusting pivot 420 is horizontally arranged. The two second pivot nuts are coaxially fixed at opposite ends inside the second adjusting pivot 420.

The end of each second pivot bolt 450 facing away from the second pivot nut is also provided for abutting against the second movable arm assembly 410 facing away from the second adjusting pivot 420. The second abutment part on one side of 20 (not shown in the figure) allows the second adjusting shaft 420 to be unlocked by reverse-tightening the two second rotating shaft bolts 450, so that each second abutment part of the two second rotating shaft bolts 450 separates from the second movable arm assembly 410, thereby allowing the second adjusting shaft 420 to rotate on its own. By forward-tightening the two second rotating shaft bolts 450, so that each second abutment part of the two second rotating shaft bolts 450 abuts against the second movable arm assembly 410, the second adjusting shaft 420 can be locked, thereby preventing the second adjusting shaft 420 from rotating on its own. In this way, the tilt angle of the second adjusting screw 430 is adjusted adaptively by the second adjusting shaft 420 and the tilt angle is kept constant.

[0033] Please refer to the following: Figure 3 and Figure 4 The first clamping unit 300 further includes a first fixing nut 360, a first adjusting nut 370, and a first rotating handle 380.

The first rotating handle 380 is fixedly disposed at the end of the first adjusting screw 330 facing away from the clamping area. Thus, through... By reverse-tightening the first adjusting nut 370, the first adjusting nut 370 and the first fixing nut 360 are relatively separated, thus unlocking the first arc-shaped clamp 340 and allowing it to rotate freely. By forward-tightening the first adjusting nut 370, the first adjusting nut 370 and the first fixing nut 360 are tightly engaged and abut against the first arc-shaped clamp 340, thus locking the first arc-shaped clamp 340 and preventing it from rotating freely. In this way, the rotation angle of the first arc-shaped clamp 340 is adjusted adaptively and kept constant.

[0034] Please refer to the following: Figure 3 and Figure 5 The second clamping unit 400 further includes a second fixing nut 460, a second adjusting nut 470, and a second rotating handle 480. The second adjusting screw 430 is radially threaded to the center of the second adjusting shaft 420.

The second rotating handle 480 is fixedly disposed at the end of the second adjusting screw 430 facing away from the clamping area. Thus, through... By reverse-tightening the second adjusting nut 470, the second arc-shaped clamp 440 is unlocked, allowing it to rotate freely, as it engages and disengages from the second fixing nut 460. By forward-tightening the second adjusting nut 470, the second adjusting nut 470 engages and disengages from the second fixing nut 460, locking the second arc-shaped clamp 440 and preventing it from rotating freely.
