firstly, a knife rest 10 is arranged on a workbench 1, the knife rest 10 is pressed and fixed through a fixing bolt 9, the installation of the knife rest 10 is completed, a second hydraulic rod 11 is started, a reflecting frame 12 and a first adapting plate 13 are driven to contact the right side of the knife rest 10 leftwards, when the first adapting plate 13 contacts the knife rest 10 and is not parallel to the knife rest 10, the first adapting plate 13 and the knife rest 10 are extruded through contact and extrusion to rotate, the reflecting frame 12 and the second hydraulic rod 11 are driven to rotate, and the hinge joint between the second hydraulic rod 11 and the right fixing plate 3 is used for adapting the rotation of the second hydraulic rod 11, so that the contact surfaces of the reflecting frame 12 and the first adapting plate 13 and the knife rest 10 are kept parallel, and an extrusion sleeve 15 is extruded to slightly deform under the action of the second hydraulic rod 11;
then, the first hydraulic rod 7 is started and drives the connecting cylinder 8, the sleeve 18, the connecting block 19, the hinging block 20 and the second adapting plate 16 to move rightwards, so that the right rear side of the second adapting plate 16 is in contact with the left side of the tool rest 10, the second adapting plate 16 rotates until the second adapting plate 16 is in contact with the left side of the tool rest 10 in a contact manner in the moving process, at the moment, the second adapting plate 16 drives the hinging block 20 to rotate, the hinging adaptation of the second adapting plate 16 and the hinging block 20 is completed, at the moment, after the second adapting plate 16 is in contact with the tool rest 10, the first hydraulic rod 7 drives the connecting cylinder 8 to continuously move rightwards, as shown in fig. 4 and 5, the first spring 26 is continuously compressed until the left side of the inner wall of the connecting cylinder 8 is in press contact with the left end of the sleeve 18, the second adapting plate 16 rotates in a contact manner with the telescopic column 22, at the left side of the telescopic column 22 is in contact with the telescopic column 22, at the moment, the second adapting plate 16 is connected with the second adapting plate 16, the second adapting plate 27 is uniformly compressed and is uniformly distributed on the basis of the second adapting plate 20, and the second adapting plate is uniformly compressed on the basis of the second adapting plate 20, and the second adapting plate is in contact with the telescopic column 22, and the second adapting plate is uniformly compressed on the basis of the second adapting plate 20, and the second adapting plate is in contact with the telescopic column 20, and the second adapting plate is uniformly compressed, and the second adapting plate 20 is in contact with the telescopic column, and the second adapting plate is in contact with the telescopic column, and the second adapting plate is uniformly, and the second adapting plate is in contact with the telescopic column, and the right;
then, setting the second adapting plate 16 and the tool rest 10 to be in an original state after the adapting pressing contact is completed, recording the pressure generated by the first hydraulic rod 7 at the moment as F, starting the laser lamp 17, enabling laser generated by the laser lamp 17 to irradiate into the reflecting frame 12, reflecting laser rays through two groups of reflecting mirrors 25 on the inner wall of the reflecting frame 12 as shown in fig. 4 and 9, finally falling on the laser capturing plate 6, and recording the falling point of the laser rays at the moment;
finally, the hydraulic lever 7 is continuously started and extended rightward, the pressure is set to f, and the following is injected: f is the reaction force that cutter on the knife rest receives when processing the work piece, drive connecting cylinder 8, sleeve 18 and No. two adapter plates 16 are exerted pressure to knife rest 10 is whole, the slight displacement of knife rest 10 that produces slight deformation can take place to the right to make laser ray take place slight skew and react the skew of the landing point on laser catch plate 6, at this moment, the atress condition of knife rest 10 presents with the deformation volume (namely rigidity) that knife rest 10 takes place after receiving operating pressure this moment, through the skew equivalent replacement of laser ray, the atress test of knife rest 10 possesses the advantage that test condition is reasonable, the test result is accurate.
