Tension-pressure conversion aid for calibration of tensile machine

The invention relates to a tension-pressure conversion aid for a calibration of tensile machine, which comprises a left tensile plate, a right tensile plate, two left tensile rods and two right tensile rods. Each of the left tensile plate and the right tensile plate is provided with four tensile rod holes in uniform distribution, two ends of the two left tensile rods and two ends of the two right tensile rods are provided with screws, the two left tensile rods penetrate through the two tensile rod holes on each of the left tensile plate and the right tensile plate, one end of each left tensile rod is fixedly connected with the right tensile plate, the other end of each left tensile rod is fixedly connected with a left three-hole tensile plate, and a left tensile ring is fixedly connected to the middle of the outer lateral side of the left three-hole tensile plate. The two right left tensile rods penetrate through the two tensile rod holes on each of the left tensile plate and the right tensile plate, one end of each right tensile rod is fixedly connected with the left tensile plate, the other end of each right tensile rod is fixedly connected with a right three-hole tensile plate, and a right tensile ring is fixedly connected to the middle of the outer lateral side of the right three-hole tensile plate. Using standard pressure sensor for calibration of the tensile machine is realized by means of the tension-pressure conversion aid, and the tension-pressure conversion aid can be used with the tensile machine for researching on material pressure withstand performance, so that application range of the tensile machine is widened.
