[0031] A fixed hydraulic rod 26 is fixedly mounted on the top of the bottom plate 22 , a connecting block 27 is fixedly mounted on the output end of the fixed hydraulic rod 26 , and the bottom of the fixed column 24 is fixedly mounted on the top of the connecting block 27 .

[0032] The fixing columns 24 are located at the upper and lower sides of the top plate 21 , and the fixing columns 24 are evenly arranged inside the top plate 21 .

[0033] In this embodiment, when fixing the workpiece, the workpiece is placed on the fixed column 24, and the fixed hydraulic rod 26 at the corresponding position is started according to the shape of the workpiece. The fixed hydraulic rod 26 drives the corresponding fixed column 24 to move, and the corresponding fixed column 24 is moved up or down to make the fixed column 24 rest against the corresponding position on the workpiece, so that multiple fixed columns 24 can be attached to the outer surface of the workpiece, so that the irregular workpiece can be stably fixed above the fixed column 24, which solves the problem that the irregular workpiece is easily offset during extrusion detection.

[0034] Reference Figures 1 to 4In one aspect of the present embodiment, the protective assembly 3 includes a cross rod 33, which is fixedly mounted at the bottom of the output end of the extrusion hydraulic rod 6, and an extrusion column 34 is fixedly mounted at the bottom of the cross rod 33, and a protective cover 31 is slidably connected to the outer side of the extrusion column 34, and a bottom frame 32 is fixedly mounted on the top of the top plate 21, and the protective cover 31 and the bottom frame 32 are located on the outer side of the fixed column 24.

During detection, the cross rod 33 and the extrusion column 34 are driven downward by starting the extrusion hydraulic rod 6, and the protective cover 31 is driven downward. The protective cover 31 first contacts the bottom frame 32, and then the extrusion column 34 continues to move downward, the spring 35 is compressed, and the extrusion column 34 moves downward to drive the extrusion head 37 and contact the workpiece below. The workpiece is squeezed by the extrusion head 37, and the test data is recorded by the pressure sensor 36.
