Embodiment Construction
[0015] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.
[0016] figure 1 It is a structural schematic diagram of the present invention.
[0017] In order to realize the clamping and fixing of the crossbeam 5, the present invention includes a column 6, a crossbeam 5 and a crossbeam clamping cylinder 4, and multiple sets of crossbeam clamping cylinders 4 are installed on the four corners of the crossbeam 5, and the crossbeam clamping cylinder on each corner 4 is responsible for the fixing of this position and the column 6. When the beam clamping cylinder 4 is clamped, the beam 5 is fixed on the column 6. When the beam clamping cylinder 4 is loosened, the beam 5 is loosened by its own elasticity. At this time, the beam 5 can move along the column 6 after being acted by external force.
[0018] In order to realize the movement of the beam 5 , the present invention also includes a fixed plate 1 , a clampin...

The invention discloses a clamping and moving device and method of a cross beam of a horizontal type tensile and compression testing machine. The device comprises a column, the cross beam and cross beam clamping cylinders, wherein the cross beam clamping cylinders are installed on the four corners of the cross bean; and the cross beam is clamped or released from the column through the cross beam clamping cylinders. The device further comprises a push-pull oil cylinder, a fixing plate and fixing plate clamping cylinders, wherein the fixing plate is arranged in parallel to the cross beam; the fixing plate is clamped or released from the column through the fixing plate clamping cylinders; the push-pull oil cylinder is arranged inside a frame and positioned between the cross beam and the fixing plate; the push-pull oil cylinder is a double action hydraulic cylinder; the piston and the cylinder barrel of the push-pull oil cylinder are respectively linked with the cross beam and the fixing plate; and hydraulic oil paths of the fixing plate clamping cylinders, the push-pull oil cylinder and the cross beam clamping cylinders are switched under electric control so as to clamp, release and move along the column in a stepless adjustment mode. By combining cross beam hydraulic clamping and hydraulic pushing, the resource of a testing machine is sufficiently utilized, occupied field is small and operation is convenient.
Description
technical field [0001] The invention relates to a clamping and moving device for a beam of a testing machine, in particular to a clamping and moving device for a beam of a horizontal tensile and compression testing machine with relatively large test space adjustment. Background technique [0002] With the progress and development of society, testing machines are used more and more widely as equipment for material testing and testing. For some large materials or structural parts, a testing machine that can adjust the test space to a large extent is needed to perform tension, compression or fatigue tests on materials or components, such as horizontal tension and compression testing machines. The crossbeam (moving beam) needs to adjust the test space at any time according to the length of the test piece. For large horizontal tensile and compression testing machines, the crossbeam is generally fixed by a bolt structure or a bolt fastening structure. The former fixing method requ...
