Problems solved by technology

[0003] It can be seen that when the existing laboratory vertical drilling coring machine takes cores from different positions of the same test piece, it needs to loosen and tighten the clamping device many times, and each time the clamping force is a serious problem to the test piece. If the damage is too large, the test piece will be damaged if the strength is slightly greater, resulting in the inability to take cores multiple times; at the same time, multiple operations are very troublesome, time-consuming and laborious, and the efficiency of coring is low

Embodiment 1

[0031] Such as figure 1 As shown, a vertical drilling and coring machine with arbitrarily positioned test piece trays includes a frame 3, a test piece tray 7, and a base 10. The frame 3 is fixed on the frame support 1 and the test piece tray 7 A clamp 6 is provided on it.

[0032] The frame 3 and the test piece disk 7 are connected by a cantilever type telescopic component; the cantilever type telescopic component can adjust the distance between the frame 3 and the test piece disk 7 through expansion, and the cantilever type telescopic component and the machine The frame 3 and the test piece disk 7 are rotatably connected, and a base 10 is also provided directly under the test piece disk 7, and the test piece disk 7 is suspended above the base 10 under the support of a cantilever telescopic assembly. A positioning device is also arranged between 7 and the base.

Embodiment 2

[0034] The structure of Embodiment 2 is the same as that of Embodiment 1, the difference lies in:

[0035] Such as Figure 2-3 As shown: the cantilever telescopic assembly includes four equal lengths of a first arm 41, a second arm 42, a third arm 43, and a fourth arm 44, the first arm 41 and the second arm One end of the arm 42, the third arm 43 and the fourth arm 44 is hinged through the rotating shaft 5, the other end of the first arm 41, the third arm 43 is rotatably connected to the frame, and a snap ring 11 is provided at the rotating connection. .

[0036] The other ends of the second arm 42 and the fourth arm 44 are rotatably connected with the bottom of the test piece disk 7, and a fixed ring 12 is provided at the bottom rotative connection.

[0037] The test piece disc is in the shape of an inverted T, and includes an upper disc body 71 and a cylindrical lower connecting column 72. Bearings are arranged between the second and fourth support arms 42 and 44 and the lower co...

Embodiment 3

[0040] The structure of Embodiment 3 is the same as that of Embodiment 2, the difference lies in:

[0041] Such as Figure 4 As shown, the positioning device is a bottoming bolt 8. The bottoming bolt 8 includes a hemispherical end, a plurality of through holes are arranged at intervals on the edge of the test piece disk, and the upper surface of the base is evenly densely covered with hemispherical grooves 9. The bottoming bolt 8 passes through the through hole, and the hemispherical end of the bottoming bolt 8 is clamped in the hemispherical groove 9 of the base to position the test piece plate.

[0042] There are 3 bottom bolts 8 evenly arranged along the edge of the test piece disk, and the top surface of the test piece disk 7 is also provided with a bubble level.

Abstract

The invention discloses a vertical drilling and coring machine with arbitrarily positioned test piece disk, which comprises a frame, a test piece disk and a base, the frame and the test piece disk are connected by a cantilever telescopic assembly, and the cantilever The cantilever-type telescopic assembly is four arms hinged by symmetrically arranged rotating shafts. The cantilever-type telescopic assembly is rotatably connected with the frame and the specimen disk. A base is also provided directly below the specimen disk. Supported by the cantilever telescopic assembly, it is suspended above the base, and the base is provided with a hemispherical groove, and the test piece plate is fixed with the hemispherical groove of the base through the touch-down bolt with a hemispherical end. The technical effect of the invention is: the position of the test piece disk can be adjusted arbitrarily, multiple elastic clamps are avoided, and the coring efficiency is improved.

Description

Technical field [0001] The invention relates to a vertical drilling and core machine, in particular to a laboratory vertical drilling and core machine. Background technique [0002] The test piece disc and the base of the existing vertical drilling and coring machine for laboratory use are fixedly connected, and the test piece clamping device is provided on the test piece disc. During the operation, the test piece is fixed on the test piece plate by the clamping device, and the coring bit fixed on the frame moves down to drill the core. After a coring is completed, the experimenter needs to use a wrench to loosen the clamping device, change the position of the test piece, and fix the test piece through the clamping device again to ensure the development of the coring work. [0003] It can be seen that when the existing laboratory vertical drilling and coring machine takes cores from different positions of the same test piece, it is necessary to loosen and tighten the clamp device ...
