Description

Technical Field

[0001] The utility model belongs to the technical field of building construction equipment, in particular to a cutting machine for building construction. Background Art

[0002] With the development of modern mechanical processing industry, the requirements for cutting quality and precision are constantly increasing, and the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also increasing. There are many types of building specimens, including concrete specimens, steel specimens, mortar specimens, brick specimens, etc. These specimens are materials used in the construction process, so their performance and quality have an important impact on the safety and durability of the building. Most of the existing building specimens are cylindrical specimens. When evaluating the internal structure and properties of the material, it is necessary to expose the internal cross-section of the specimen in order to observe its internal organization, structure and material. Usually, the cylindrical specimen is sliced. By slicing the specimen, the microstructure and properties of the material, such as porosity, density, strength, etc., can be understood.

[0003] The Chinese patent with the publication number: CN220838244U discloses a construction sample cutting machine, including a cutting tool and a sample fixture, the cutting tool includes a rotary cutting blade that can be translated laterally, the sample fixture includes a base, the base is provided with a limit column and a support column arranged side by side, a support bar is provided on the base between the limit column and the support column, a pressure rod is hinged at the top of the support column, the end of the pressure rod is detachably connected to the top of the limit column, a pressure plate is fixed at the bottom of the pressure rod, a circular arc sample bayonet is provided on the bottom edge of the pressure plate, and the bottom of the rotary cutting blade is vertically located between the top surface of the base and the top surface of the support bar. This technology can solve the problem that the construction sample is fixed at both ends in the prior art, the length of the cut sample is limited, and the end of the sample cut seam is easily pushed and broken by the blade during the cutting process, resulting in an uneven cut surface;

[0004] However, in actual use, it was found that this cutting machine clamps the sample through the sample clamping hole on the pressure plate, but a plurality of sample clamping holes are opened on the pressure plate along the length direction, and the opening diameter of the sample clamping hole is fixed. In this way, when it is necessary to clamp samples of different specifications, it is impossible to clamp each sample in place. For example, when clamping a larger sample, the pressure plate as a whole is finally tilted, and the sample close to the rotating end of the pressure plate is clamped, while the sample at the other end is not clamped. As a result, the use of this cutting machine is only applicable to samples of one specification, and the scope of application is small, and there is still room for improvement. Utility Model Content

[0039] The clamping unit is used to clamp the sample 100, and the cutting unit 2 can cut the sample 100 clamped by the clamping unit on the cutting track;

[0040] In this embodiment, the clamping unit includes: a positioning seat 3, a movable seat 4, a clamping plate 5,

[0041] The positioning seat 3 is disposed on the base 1 , and a plurality of positioning grooves 301 with V-shaped cross sections are provided on the positioning seat 3 at intervals along the sliding direction of the cutting unit 2 , and each positioning groove 301 can hold a sample 100 ;

[0042] The movable seat 4 is arranged above the positioning seat 3; the clamping plate 5 is located below the movable seat 4, each positioning groove 301 corresponds to a clamping plate 5, and the distance between each clamping plate 5 and the movable seat 4 can be adjusted separately;

[0043] When clamping the sample 100, first adjust the clamping plate 5 upward to be away from the positioning seat 3, so that there is space between the clamping plate 5 and the positioning groove 301 for placing the sample 100, and then place the sample 100 in the positioning groove 301, so that the outer peripheral wall of the sample 100 contacts the two side walls of the positioning groove 301, and then adjust the clamping plate 5 downward to make the clamping plate 5 close to the sample 100, and finally the clamping plate 5 contacts the sample 100 and continues to squeeze the sample 100 downward, so that the clamping plate 5 cooperates with the positioning groove 301 to clamp the sample 100 in place;

[0044] The cutting unit 2 includes a motor, a circular blade, a guide rail 12, and a sliding frame 13;

[0045] The guide rail 12 is arranged on the base 1 along the length direction of the positioning seat 3, the sliding frame 13 is arranged on the guide rail 12 to slide along the setting direction of the guide rail 12, the motor is arranged on the sliding frame 13 and can move with the sliding frame 13, and the output shaft of the motor is coaxially connected with the circular blade to drive the circular blade to rotate;

[0046] In this embodiment, all the clamps 5 are adjusted upward, and a sample 100 is placed in each positioning groove 301. After the sample 100 is placed, all the clamps 5 are adjusted downward in sequence, so that the clamps 5 contact the sample 100 and cooperate with the corresponding positioning groove 301 to clamp the sample 100. The clamping state of the sample 100 is as follows: Figure 5 As shown, after all the samples 100 in the positioning grooves 301 are clamped, the motor is started to drive the circular blade to rotate, and the sliding frame 13 is driven by external force to slide on the guide rail 12 toward the sample 100. During this process, the circular blade contacts all the samples 100 in turn, thereby cutting all the samples 100 clamped in the positioning grooves 301.
