Description

Technical Field

[0001] The utility model relates to the field of metallographic sample grinding, in particular to a high-efficiency metallographic sample surface grinding device. Background Art

[0002] In the study of materials, the grinding of metallographic samples is an indispensable link. At present, the common practice is to place the sample flat on the sandpaper on the work surface, keep the sample in full contact with the sandpaper, and the operator holds the sandpaper with one hand to fix it, and holds the side of the sample with the other hand, relying on the friction generated by the relative movement between the sample and the sandpaper to gradually reduce the roughness of the sample surface. If a large number of samples need to be prepared, holding the sample for a long time for grinding will cause soreness and fatigue in the operator's fingers and a slow grinding rate. Sometimes, because the operator's fingers do not exert force evenly, the ground surface of the sample will become uneven or have a new surface. Summary of the invention

[0003] In view of the above problems, this utility model patent designs a high-efficiency metallographic sample surface grinding device.

[0004] The problem solved by the utility model is achieved through the following solutions:

[0005] A high-efficiency metallographic sample surface grinding device comprises a hand wheel (1), a pin (2), a spiral rod (3), a bracket (4), a screw sleeve (5), a box (6), a mechanical claw (7), a wheel (8), a shaft (9), an abrasive belt (10), a bolt (11), and a motor (12). The hand wheel (1) and the spiral rod (3) are fixedly connected via the pin (2).

[0006] In the utility model, a screw sleeve (5) is installed inside the bracket (4) to fix the screw rod (3), wherein the screw rod (3) is connected to the mechanical claw (7) of the clamped sample, and the sample is controlled to be raised or lowered to a suitable position through the hand wheel (1).

[0007] In the utility model, the bracket (4) is fixed to the box body (6) by bolts (11), and a motor (12) is arranged inside the box body (6) and connected to the sanding belt (10) to drive the sanding belt (10) to rotate at high speed, thereby grinding the sample surface with high efficiency.

[0008] In the utility model, a wheel (8) and a shaft (9) are provided at the bottom of the device, and the two are connected to each other and are used for the high-speed operation and rotation of the sanding belt (10).

[0009] In the utility model, the motor drives the sanding belt to rotate at a high speed, and the grinding speed of the sample surface is fast. There is no need to manually hold the sample for grinding, which effectively avoids the operator's finger soreness and fatigue caused by long-term holding of the sample for grinding, and the uneven force of each finger of the operator, which makes the grinding surface of the sample uneven or new, thereby improving work efficiency and safety.
