The auxiliary assembly 22 comprises a support body 223, and at least two round rollers 221 for clamping and fixing the core sample and a positioning roller 222 for supporting and positioning are arranged on the support body 223. When the core sample is sliced, the clamping mechanism 2 and the auxiliary mechanism clamp the core sample together, so that the clamping of a single clamp is reduced, and the possibility of deflection due to unbalanced stress when the core sample is cut for a long time is reduced.

In order to better clamp the core sample, the clamping block 212 is rectangular, and one surface of the clamping block 212 for clamping the core sample is provided with a V-shaped groove penetrating through the clamping block 212. The round roller 221 is a rotating body, and the side of the axial cross section of the round roller 221 is hyperbolic. The positioning block 213 and the clamping block 212 have the same shape and size, and the positioning roller 222 and the round roller 221 have the same shape and size, so that when the core sample is clamped, the cylindrical core sample is clamped on the V-shaped groove of the clamping block 212 and the concave side surface of the round roller 221, and the clamping stability is further facilitated.

The fixture body 211 comprises a sliding table 2111 and a tripod 2112, the sliding table 2111 is a rectangular plate, the tripod 2112 comprises two supporting plates with the same shape and size and similar rectangular plates, one end of each of the two supporting plates is welded to enable the two supporting plates to be fixed, an included angle between the two supporting plates is 60 degrees, and one ends, far away from the welding point, of the two supporting plates are welded to the upper surface of the sliding table 2111. An isosceles triangle space is formed between the inner side surface of the tripod 2112 and the upper surface of the sliding plate. The positioning block 213 is fixedly connected to the upper surface of the sliding table 2111, one end of the positioning block 213 where the V-shaped groove is located is welded upward to the upper surface of the sliding table 2111, and the positioning block 213 is located at the center of the bottom surface of the triangular space formed between the inner side surface of the tripod 2112 and the upper surface of the sliding plate. The clamping blocks 212 are slidably mounted to the two support plates of the tripod 2112, respectively, and when clamping the fixed core sample, the clamping blocks 212 and the positioning blocks 213 are uniformly arranged along the circumference of the core sample. In order to facilitate the sliding of the clamping block 212 on the supporting plate and the fixation after the sliding, the supporting plate is in threaded connection with a threaded rod 23, the threaded rod 23 is rotatably connected with a U-shaped frame 24, and the clamping block 212 is fixedly connected on the U-shaped frame 24. The U-shaped frame 24 includes a transverse plate and two longitudinal plates fixedly connected to both ends of the transverse plate, and a rectangular groove-shaped space is formed between the two transverse plates and the longitudinal plates. The through hole is arranged at the center of the transverse plate, the U-shaped frame 24 is rotatably connected with a bolt, the bolt penetrates through the through hole in the transverse plate, one end of the bolt penetrating out of the transverse plate is welded at one end, close to the U-shaped frame 24, of the threaded rod 23, and the diameter of the through hole is larger than that of the bolt and smaller than that of a bolt head of the bolt. The clamping block 212 is welded between the two longitudinal plates, and the clearance between the clamping block and the transverse plate is ensured to prevent the relative rotation between the U-shaped frame 24 and the threaded rod 23. After the core sample is placed on the positioning block 213, the threaded rod 23 is rotated to drive the two clamping blocks 212 capable of sliding to clamp the core sample.

In order to facilitate continuous cutting, a sliding groove 11 is formed in the base 1, the sliding table 2111 can be slidably mounted in the sliding groove 11, one surface, away from the auxiliary mechanism, of the sliding table 2111 is rotatably connected with a pushing screw 12, and the pushing screw 12 penetrates through the sliding groove 11, is away from the side wall of the auxiliary mechanism and is in threaded connection with the side wall. The base 1 is engraved with graduation lines 13, the graduation lines 13 are arranged along the sliding direction of the sliding table 2111, and for the convenience of observation, one end of the graduation line 13 is attached to the side wall of the sliding groove 11 close to the graduation line 13. When the core sample needs to be cut continuously, the sliding table 2111 can be pushed to drive the whole clamp assembly 21 to slide towards the cutting assembly 4 by rotating the threaded push rod, and the sliding amount, namely the thickness of the slice, can be determined by the position of the sliding table 2111 relative to the scale mark 13.

The auxiliary assembly 22 comprises a support body 223, the support body 223 is the same as the tripod 2112 of the clamp assembly in shape and size, the support body 223 is also connected with the threaded rods 23 and the U-shaped frames 24 which are the same in number as the round rollers 221, and the connection mode of the support body 223 with the threaded rods 23 and the U-shaped frames 24 is the same as that of the tripod 2112 with the threaded rods 23 and the U-shaped frames 24. The support plate on the support 223 of the auxiliary assembly 22 is welded to the base 1 at the end remote from the weld between the two support plates. Two longitudinal plates of the U-shaped frame 24 of the auxiliary assembly 22 are respectively provided with a through hole, the through holes on the two longitudinal plates are coaxial, the circle centers of two ends of the circular roller 221 are welded with short shafts, and the two short shafts are respectively and rotatably arranged in the two through holes, so that the circular roller 221 can freely rotate under the support of the U-shaped frame 24.

After the core sample is placed on the positioning roller 222 on the base 1, the threaded rod 23 is rotated to drive the round roller 221 to clamp the core sample. When the clamp assembly 21 slides by pushing the screw 12, the core sample moves and rubs the surfaces of the round roller 221 and the positioning roller 222, so that the round roller 221 and the positioning roller 222 are driven to rotate, and the core sample can slide while the clamping of the auxiliary assembly 22 is not loosened.

In order to keep away from the saw blade 41 after the chips cut by the core sample fall, the chute 3 is formed in the base 1, one side of the chute 3 is attached to the plane where one side of the saw blade 41 far away from the clamping mechanism 2, the bottom surface of the chute 3 is an inclined surface, the inclined surface can roll to be far away from the saw blade 41 after the chips fall, the saw blade 41 can be kept away when the worker picks up the saw blade 41, and the danger caused by the saw blade 41 can be reduced.

The implementation principle of the embodiment is as follows: when core sample slicing is required, the core sample is placed on the fixed positioning block 213 and the positioning rollers 222, and then the four threaded rods 23 are tightened to clamp the other clamping blocks 212 and the round rollers 221 to fix the core sample. The threaded push rod is rotated to push the sliding table 2111 to move, the thickness of the core sample extending out of the saw blade 41 reaches the thickness required by the experiment by referring to the scale mark 13, and the cutting assembly 4 is started to finish cutting. When multiple cutting is needed, the threaded push rod is continuously rotated to push the sliding table 2111 to move, the scale mark 13 is referenced, the thickness of the core sample extending out of the saw blade 41 reaches the thickness required by the experiment, the cutting assembly 4 is started to finish cutting, and the like. The cut slices fall into the chute 3 and roll away from the saw blade 41 along the slope of the chute 3 to reduce the risk that the worker may get too close to the saw blade 41 when picking up the slices.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
