Detecting a machine foot glue body: if the automobile engine emits obvious noise or abnormal vibration occurs on the automobile body, the external detection electric push rod 12 drives the external pressure sensing head 13 to move towards the rubber shock absorbing member 2 until the external pressure sensing head 13 contacts with the rubber shock absorbing member 2 and extrudes the rubber shock absorbing member 2, so that the elasticity and toughness of a pressed area of the rubber shock absorbing member 2 are judged by recording the stroke length of the external detection electric push rod 12 and the pressure sensed by the external pressure sensing head 13, meanwhile, the electric slide table 11 can drive the external detection electric push rod 12 to move up and down, the driver 15 can carry the electric slide table 11 to perform arc sliding along the arc guide rail 14, so that the position of the external detection electric push rod 12 is changed, the external pressure sensing head 13 can perform multi-point detection on the part of the rubber shock absorbing member 2 positioned outside the alloy upper shell 1, so as to obtain the current hardness and aging degree of the rubber shock absorber 2, meanwhile, the internal detection electric push rod 16 can drive the internal pressure sensing head 17 to move towards the alloy upper shell 1, the internal pressure sensing head 17 is in butt joint with the butt joint groove 1901 on the opening and closing arc plate 19, then the driver 15 drives the internal detection electric push rod 16 to move along the arc guide rail 14, and further drives the opening and closing arc plate 19 to slide on the opening and closing slide rail 18, so that the inspection arc hole 101 is opened, the internal pressure sensing head 17 is inserted into the inspection arc hole 101 to detect the part of the rubber shock absorber 2 positioned at the inner side of the alloy upper shell 1, meanwhile, the internal pressure sensing head 17 is matched with the driving of the arc guide rail 14 and the driver 15 to detect multiple points of the rubber shock absorber 2 at the inner side, the condition of the foot rubber body is directly detected, the reasons of abnormal conditions of engine noise and vehicle body vibration are examined, and when outside part of rubber shock absorber spare 2 is examined to outside pressure sensing head 13, the outside detection electric putter 12 top the fluid inductor 28 can contact the surface of rubber shock absorber spare 2 simultaneously, if when crack and damage appear on the surface of rubber shock absorber spare 2, lead to the inside sealed oil pocket of rubber shock absorber spare 2 when damaged oil leak, fluid can be along the surface of rubber shock absorber spare 2 downwardly sliding, and fluid inductor 28 can carry out the response to the fluid of the surface of rubber shock absorber spare 2 and detect this moment, carries out further investigation for the damage reason of the machine foot rubber body.
