DETAILED DESCRIPTION

[0024] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0025] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0026] Reference Figure 1-4 The utility model provides a metallographic test sample preparation grinding tool, comprising: a limiter 1 and a handle 2.

[0027] The bottom surface of the limiter 1 has a plurality of limit grooves 11 evenly distributed along the length direction, the depth of the limit grooves 11 is less than the diameter of the screw of the bolt, so that the part to be ground out extends from the bottom surface, and the length of the limit grooves 11 is less than or equal to the length of the screw of the bolt. The limiter 1 is, for example, a rectangular block with a rectangular cross section, and the material can be hard metal. The cross-sectional shape of the limit groove 11 is, for example, a fan-shaped, so that the bolt part placed in the limit groove 11 extends from the bottom surface of the limiter 1. When the staff uses it, they hold the handle 2, and then place multiple bolts to be ground in the limit groove 11, start the grinding equipment at the bottom, and quickly grind the multiple bolts, which simplifies the grinding difficulty, reduces the risk of accidents caused by workers' grinding, improves safety, and can grind multiple bolts at a time, improving work efficiency. The handle 2 is connected to the top surface.

[0028] In one embodiment, the limiting member 1 includes a fixed member 12 and a movable member 13, and an adjusting groove 121 is provided on the fixed member 12 near the bottom surface, and the movable member 13 can move along the length direction of the limiting member 1 in the adjusting groove 121, and the limiting groove 11 includes a first limiting groove 111 and a second limiting groove 112, wherein the first limiting groove 111 is provided on the fixed member 12, and the second limiting groove 112 is provided at the bottom of the movable member 13. The adjusting groove 121 is provided on the fixed member 12, and is horizontally penetrated in the horizontal direction, and has openings on both sides, so that the movable member 13 can extend partly from the openings on both sides. The two side arc surfaces that the first limiting groove 111 butts with are the arc surfaces of the two side parts of the bolt, and the first limiting groove 111 butts with the top and the arc segments on both sides of the bolt.

[0029] The locking member 3 is connected to both sides of the fixed member 12 and the movable member 13, and is used to squeeze the fixed member 12 and the movable member 13 from both sides to make the first limiting groove 111 and the second limiting groove 112 cooperate with the screw of the locking bolt. The locking members 3 on both sides make the locking members 3 on both sides, and the locking members 3 can be connected to both sides of the fixed member 12 by bolts, buckles, etc., so that the movable member 13 after abutment has a lateral thrust along the length direction of the adjustment groove 121. Under the thrust of the locking member 3, the two first limiting grooves 111 and the second limiting grooves 112 with a tendency to move relative to each other cooperate from different positions respectively, and the bolt is locked, so that the unlocked bolt is clamped from both sides of the top of the stud, and the position of the bolt can be locked on the basis of facilitating the operator to clamp multiple times, so as to prevent the bolt from flying and collapsing during the grinding process, and the locking position can prevent the grinding position from being not unique, causing the bolt to rotate and damage the bolt sample, thereby improving safety.

[0030] In a specific embodiment, the movable member 13 has a first sliding surface 4 at the top located in the adjustment groove 121, and the fixed member 12 has a second sliding surface 5 in the corresponding adjustment groove 121. During adjustment, the fixed member 12 and the movable member 13 cooperate through the first sliding surface 4 and the second sliding surface 5 to prevent the position of the movable member 13 in the vertical direction in the fixed member 12 from changing, wherein the first sliding surface 4 and the second sliding surface 5 can be two planes parallel to the horizontal plane, or can be inclined planes with an angle to the horizontal plane, to prevent the movable member 13 from moving upward when working as a component of the clamping bolt, causing part of the bolt abutting in the second connecting groove to fall off and lose the locking effect.

[0031] More specifically, the locking member 3 includes a pad 31 and an adjusting bolt 32, wherein the pad 31 is connected to the fixing member 12 through the adjusting bolt 32 and abuts against the moving member 13. Threaded holes are provided on both sides of the fixing member 12, and the position between the moving member 13 and the fixing member 12 is adjusted by adjusting the bolt 32 to achieve the purpose of locking the bolt.

[0032] A sample preparation system comprises any one of the above-mentioned metallographic test sample preparation abrasive tools.

[0033] It also includes: a grinding wheel assembly (not shown in the figure), which has a rotatable grinding wheel for grinding the bolts in the limiting groove 11 to remove the excess.

[0034] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the utility model.
