Abstract

The invention discloses an automatic online phase measuring device and method for a crankshaft connecting rod neck. The device comprises a touch sensor, a driving device of the touch sensor, a main rotating shaft, a driving device of the main rotating shaft, and a rotating angle sensor; a measuring head center line of the touch sensor and an axis of the main rotating shaft are in the same plane, and the vertical position is used as the measuring position of the touch sensor. The method comprises the steps of driving the main rotating shaft at the measuring position to drive a crankshaft to rotate in two directions from the initial position to the position in contact with a measuring head to obtain angle coordinates A1 and A2 of the main rotating shaft at two positions; calculating (A1+A2-360) / 2 to obtain the angle coordinate of the main rotating shaft when the connecting rod neck rotates to reach the horizontal position. The device is accurate to position and high in efficiency; the problem of automatic fixing the phase in the automatic processing of the crankshaft connecting rod neck can be solved well; the requirements on softness and high efficiency under automatic processing can be met.

Description

technical field [0001] The invention relates to a workpiece angle measuring device and a measuring method, in particular to an automatic on-line phase measuring device and a measuring method of a crank pin. Background technique [0002] At present, in the grinding process of the crankshaft connecting rod neck, the positioning pin hole is generally used to determine the phase, such as figure 1 As shown, the positioning pin 2 is designed on the special jig 1 for the crankshaft, and the positioning pin is fixed according to the position of the positioning pin hole on the crankshaft 3. The angle is accurate. [0003] The disadvantage of pin hole positioning is poor flexibility. Because the size of the pin hole of different types of crankshafts and the distance between the pin hole and the center of the workpiece are different, each time the type is changed, the card needs to be replaced again, which increases the cost and cycle of the type change, and cannot satisfy automation....
