Device for positioning measurement of reciprocating rudder mechanism

Abstract

A positioning and measuring device for reciprocating helm shifting mechanisms comprises a main connecting rod, auxiliary connecting rods, fastening bolts matched with the auxiliary connecting rods, a connecting sleeve, a fastening bolt matched with the connecting sleeve, a positioning stud, a sample needle, a dial indicator rod, a dial indicator clip and fastening bolts matched with the dial indicator rod and the dial indicator clip. Reinforcing rods for preventing swinging are welded on the main connecting rod, the positioning stud is used for guaranteeing measurement accuracy, and machining precision of a service surface of the positioning stud is high. The tool device can measure deflection of positions of hydraulic cylinders of the reciprocating helm shifting mechanisms in the front-back directions and the left-right directions and deflection of vertical heights of plungers of the reciprocating helm shifting mechanisms, repeated measurement is omitted, and large quantities of time are saved. Besides, when the tool device is used for measuring the positions of the hydraulic cylinders of the helm shifting mechanisms in the front-back directions and the left-right directions, scales with poor measurement precision can be omitted, and when the positioning and measuring device is used for measuring the vertical positions of the plungers, upper planes of helms with poor machining precision are not required. Accordingly, measurement precision is greatly improved, and installation quality and service quality of the helm shifting mechanisms are guaranteed.

Description

technical field [0001] The invention relates to a measuring device, in particular to a device for measuring the position of a rudder steering mechanism in the shipbuilding process. Background technique [0002] Before positioning the reciprocating rudder mechanism in marine equipment, it is necessary to measure the front, rear, left, and right positions of the hydraulic cylinder, such as Figure 13 , the distances a, b, c, and d from the center of the rudder stock to the reference point 26 on the four hydraulic cylinders must be within the required range. The traditional measurement method is to use a ruler gauge 27 to measure such as Figure 14 , fix one end of the ruler gauge 27 to the center of the rudder stock 23, and use the other end of the ruler gauge 27 to check the center of the rudder stock to the reference point 26 on the four hydraulic cylinders (such as Figure 16 Shown) whether the distance is within the required range, its disadvantages are: [0003] 1.
