Description

A rock specimen cutting and rotating fixture

technical field

The utility model relates to the field of cutting machines, in particular to a rock test piece cutting rotary fixing device.

Background technique

As a cutting tool, the traditional cutting machine has a wide range of applications and can be used to cut many metal or non-metal materials, and the cutting is fast and convenient. At present, multifunctional rock cutting machines are generally large-scale equipment with high cost and complicated operation, which is obviously not suitable for experimental research in colleges and universities. The rock specimen cutting machine generally used in college research is a small equipment, which has the advantages of simple and flexible operation, high safety factor, and low cost. But its function is also limited, especially for the cutting of square rock specimens. However, the rock specimen cutting machine used in college experiments can only meet the requirements of cutting cylindrical specimens at present, and it is difficult to cut square specimens required for experiments.

At the same time, the current fixing device for rock specimen cutting is relatively simple. Generally, a fixed baffle is installed on the cutting platform. The operator needs to fix the specimen with one hand while cutting with the other hand. The operation is difficult and dangerous. At the same time, the processing precision of the test piece made by this fixture is low, and the processing of the test piece is unqualified.

Utility model content

The utility model overcomes the above-mentioned problems, and provides a rock test piece cutting rotary fixing device with simple structure, convenient operation, capable of cutting square test pieces, and high precision of finished test pieces.

The technical scheme of the utility model is as follows: a rock test piece cutting and rotating fixing device, including a base and a rotating seat located on the base and coaxial with the base; two vertically intersecting grooves are arranged on the surface of the rotating seat, and There are 4 positioning holes evenly on the side, the center of the positioning hole is directly below the groove, and the centers of the 4 positioning holes are on a plane; one end of the detachable right-angle bolt is fixed in the positioning hole, and the other end is fixed on the base On the surface of the base and outside the rotating seat, there are two fixed rods vertically arranged, which correspond to the two ports of one of the grooves; the fixed rods are vertically pierced with support rods, and the inner ends of each support rod are provided with V V-shaped fasteners, the outer ends of which are fixed to the fixed rod by fastening bolts; the openings of the two V-shaped fasteners are opposite.

The V-angle of the V-shaped fastener is preferably 90-135 degrees. The inner surface of the V-shaped fastener is preferably provided with a buffer rubber layer, the purpose of which is to prevent the V-shaped fastener from being damaged by excessive pressure on the surface of the test piece.

Among them, the coaxial rotating seat and the base are connected by bearings, making it combined into an integral structure, and the conversion of the test piece can be completed only through the rotating positioning hole, which greatly improves the cutting accuracy and work efficiency of the test piece .

The specific operation method is:

(1) Pull the two sides of the V-shaped fastener apart, place the test piece in the center of the rotating seat, clamp the two sides of the V-shaped fastener close together, and fix it with fastening bolts; insert the right-angle bolt into the positioning hole and the corresponding hole of the base, and fix it firmly , to cut;

(2) When one side of the specimen is cut, reversely rotate the fastening bolts so that both sides of the V-shaped fastener leave the specimen, open the right-angle bolt, turn the rotating seat 90 degrees clockwise or counterclockwise, and then reinsert the right-angle bolt into the positioning hole and the corresponding hole of the base; adjust the support rod so that the V-shaped fixture re-clamps the test piece until the end of the operation;

If it is necessary to cut the remaining two sides, repeat step (2) twice. Finally, adjust the support rod, open the V-shaped fastener, take out the cut test piece, and the operation ends.

The utility model has the advantages that the V-shaped firmware is firm and reliable, the structure is simple, the base can be rotated and positioned precisely, and the operation is convenient and easy to grasp.
