The invention discloses a clamp for press fitting of a short-axis pipe. The clamp for press fitting of the short-axis pipe comprises a clamp frame, an electrical controller, a first clamping mechanism, a second clamping mechanism, a pressing mechanism, a press fitting mechanism and a clamping sensor, wherein the first clamping mechanism and the second clamping mechanism respectively comprise a clamping guide rod and a clamping oil cylinder, and the pressing mechanism comprises a pressing guide rod and a pressing oil cylinder, the press fitting mechanism comprises multiple press fitting guide rods, a press fitting oil cylinder and a downward-pressing sensor. According to the clamp for press fitting of the short-axis pipe fitting, the two clamping oil cylinders are controlled by the electrical controller to fix the pipe through clamping, and the pipe fit is arranged on a workpiece in a press fitting mode through the cooperation between the pressing mechanism and the press fitting mechanism after being fixed. According to the clamp for press fitting of the short-axis pipe, the press fitting process is simple, operation is convenient, manual participation is not needed, the automation degree is high, and the effects that press fitting positioning is accurate, pressing fitting speed is high and press fitting efficiency is high are achieved due to the fact that position signals are detected through the clamping sensors and the downward-pressing sensor; the clamp can be used for press fitting of short-axis pipes with various sizes, and the application range is widened.
