Description

Technical Field

[0001] The utility model relates to the field of clamps, in particular to a core sample clamp used for a small diamond wire cutting machine. Background Art

[0002] Paleomagnetism is a discipline that takes rocks and various sediments as its basic research objects. It studies the magnetic records of natural geological samples and analyzes their natural residual magnetization intensity and direction, and then inverts the geomagnetic field morphology of the geological history period and the structural characteristics of the research object when it is magnetized, so as to understand the geological structure, mineral occurrence, environmental changes and other important geological information of the area. In paleomagnetism related experiments, the collected samples need to be cut before the experiment to ensure that the sample surface is flat and the length is uniform.

[0003] In the prior art, a special double-knife cutting machine for paleomagnetic samples is often used to cut standard samples. It is suitable for cylindrical samples with a diameter of 25.4 mm. For small cylindrical samples with a diameter of 10 mm and samples that do not meet the expected standards after cutting with a double-knife cutting machine, a small diamond wire cutting machine is often used for fine processing and cutting. The sample is fixed by heating the sample block, resin ceramic block and sample on a heating platform and then bonding and fixing them with a paraffin rod. For cylindrical samples, hot melt adhesive is also required to strengthen the fixation to prevent rolling. After cutting, the colloid needs to be reheated to melt the sample, resin ceramic block and sample block to separate and remove the sample. This method of fixing and removing samples is inefficient, and repeated heating will have a certain impact on the magnetism of the core sample, affecting the measurement results of later experiments.

[0014] 3. After the sample is fixed, put the fixture with the sample into the slot platform of the small diamond wire cutting machine, fix and lock the carrier and the slot platform, and start cutting after the fixation is completed. After cutting one end, you can cut the other end by rotating the slot platform of the wire cutting machine. There is no need to disassemble the sample again.

DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, the present embodiment provides a core sample fixture for a small-sized diamond wire cutting machine, comprising a carrier, a clamping bolt and a rotating handle.

[0023] The carrier includes a bottom plate portion 1 arranged horizontally and a vertical plate portion 2 arranged vertically on the top of the bottom plate portion 1. The bottom plate portion 1 is a rectangular parallelepiped structure, and each of the four corners has a cutout 101, so that it can fit the slot platform of the wire cutting machine, and is convenient for fixing using the locking screws on the slot platform. The vertical plate portion 2 has a slot hole 201 for placing the core, and the slot hole 201 is provided with one, and the slot hole 201 includes a semicircular placement hole portion at the bottom and a rectangular hole portion connected above the semicircular placement hole portion. The top of the vertical plate portion 2 has a threaded hole 202 that is vertically distributed and connected to the slot hole 201. The thickness of the vertical plate portion 2 is less than the height of the sample, so that it can be directly reverse cut by rotating the slot platform of the wire cutting machine during cutting, avoiding the complicated process of disassembly and fixing; a certain distance is set between the bottom end of the slot hole 201 and the bottom plate portion 1, which can prevent the cutting line from cutting onto the carrier when working, avoiding damage to the cutting line, and improving the cutting efficiency while being convenient to use, realizing full utilization of the cutting function.

[0024] The clamping bolt includes a screw portion 3 and an assembly and disassembly platform portion 4 integrally connected to the top of the screw portion 3. The screw portion 3 has an external thread adapted to the threaded hole 202. The screw portion 3 can be screwed downward to clamp the sample placed at the slot 201 from top to bottom. The assembly and disassembly platform portion 4 has an insertion hole 401.

[0025] The rotating handle is a "Z"-shaped rod structure, including an insertion rod portion 5, a connecting rod portion 6 and a holding rod portion 7 connected in sequence. The insertion rod portion 5 can be inserted into the insertion hole 401, and the length of the holding rod portion 7 is greater than the length of the insertion rod portion 5. The user inserts the insertion rod portion 5 into the insertion hole 401, grasps the holding rod portion 7 with his hand, and rotates the rotating handle, which can drive the assembly and disassembly platform portion 4 to rotate forward and reverse, thereby driving the screw portion 3 to rotate forward and reverse, realizing the downward screwing in and upward screwing out of the clamping bolt, clamping the sample or releasing the clamping of the sample. Through the use of the carrier and the clamping bolt, the sample can be firmly fixed, and the shaking caused by cutting is avoided to a great extent.

[0026] This embodiment is durable, easy to use, and has reasonable cost. It can firmly fix the sample when the small diamond wire cutting machine is working, and can also ensure that the surface to be cut of the sample is level and meet the flatness requirements of the cutting surface. All parts of this clamp are made of non-magnetic rust-proof materials, which can reduce the impact on the magnetism of the sample, and at the same time ensure that it will not be corroded by the coolant during the cutting process, thereby increasing its service life. After the sample is fixed by the clamping bolt, the carrier is fit through the incision 101 and placed on the platform with the card slot of the small diamond wire cutting machine. After it is fixed, the cutting work can be started, which effectively replaces the method of using the sample block, the resin ceramic block and the sample to be heated on the heating platform and then adhered and fixed by the paraffin rod. This embodiment will not affect the magnetism of the core sample.

[0027] Embodiment 2

[0028] like Figure 3-Figure 5 As shown, the present embodiment proposes a core sample clamp for a small diamond wire cutting machine. Compared with the first embodiment, in the present embodiment, three slots 201 are arranged horizontally side by side, and the slots 201 correspond to the threaded holes 202 one by one, that is, three threaded holes 202 are arranged correspondingly, and the size of the threaded holes 202 in the present embodiment is smaller than the size of the threaded holes 202 in the first embodiment. The size of the slots 201 in the present embodiment is smaller than the size of the slots 201 in the first embodiment, so that it can be used to clamp samples of smaller size, and when clamping samples of smaller size, multiple samples can be clamped at the same time. The size of the clamping bolt used in the present embodiment is smaller than the size of the clamping bolt in the first embodiment, but the present embodiment and the first embodiment can share the rotating handle.

[0029] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
