Embodiment Construction
[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings.
[0025] This embodiment provides a conical test piece pressing block pre-tightening excitation device, its structure is as follows: Figure 1 to Figure 6 As shown, it includes the main part 1 and the pressure block 2 of the excitation device.
[0026] Such as figure 2 As shown, the main part 1 of the excitation device includes a test piece installation place 1-1 for installing the test piece 3 and an excitation loading bracket 1-2;
[0027] combine figure 2 with image 3 It can be seen that the test piece installation place 1-1 is a complete ring, the inner wall 10 of the ring is a conical surface, and the taper is θ, which is the same as the taper of the outer wall of the tapered test piece 3, and can be closely matched; the two sides of the inner wall 10 of the ring The end is chamfered, which is convenient for the installation and dis...

The invention belongs to the technical field of conical test piece horizontal double-stand parallel-excitation test tools, in particular to a conical test piece pressing block pre-tightening exciting device. An exciting device main body part (1) of the device comprises a test piece mounting part (1-1) and an exciting loading bracket (1-2); the inner wall of the test piece mounting part (1-1) is a conical surface and multiple pressing block grooves (7) are formed in the inner wall of the test piece mounting part (1-1); a plurality of radial through holes (11) are formed in the circular ring and used for connecting a test piece (3); the exciting loading bracket (1-2) comprises an exciting lug boss (8) and a support plate (1-3); the exciting lug boss (8) is perpendicular to the test piece mounting part (1-1); the support plate (1-3) is connected with the exciting lug boss (8) and the test piece mounting part (1-1); pressing blocks (2) are mounted in the pressing block grooves (7). The conical test piece pressing block pre-tightening exciting device has the benefits as follows: the conical test piece pressing block pre-tightening device has the advantages of firmness in mounting and high in rigidity and the problems about mounting and exciting of the horizontal double-stand parallel-excitation test of the conical test piece (3) are solved. The system is high in test frequency and meanwhile, the safety of the test product is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of horizontal double-stage parallel excitation test tooling for conical test pieces, and in particular relates to a pre-tightening excitation device for conical test piece pressing blocks. Background technique [0002] At present, the horizontal double-stage parallel excitation test of cylindrical specimens mostly adopts split excitation devices. This type of device is composed of upper and lower parts. It is clamped in it and fixed by screws. However, for conical specimens, this fixing method is easy to cause slippage during the test, so it is no longer applicable. Therefore, for the test product with a taper, it is necessary to design a new type of excitation device to achieve lateral excitation, so as to solve the above technical problems. Contents of the invention [0003] The object of the present invention is to solve the problems existing in the prior art, and provide a conical test piece pressing ...
