Cylinder cover top surface auxiliary hole pitch measuring tool

Abstract

The invention discloses a cylinder cover top surface auxiliary hole pitch measuring tool. The cylinder cover top surface auxiliary hole pitch measuring tool comprises a measuring plate, a fixed elastic pin, a limiting block, a sliding guide rail assembly, a movable elastic pin and a dial indicator, wherein the fixed elastic pin is inserted into one end of the lower surface of the measuring plate;the limiting block is fixed in the middle of the lower surface of the measuring plate; the sliding guide rail assembly comprises a connecting plate, fixed sliding seats, a movable sliding seat and baffle plates; the baffle plates are arranged on the upper side and the lower side of the connecting plate, and the fixed sliding seats are fixed to the left side and the right side of the connecting plate to define a movable sliding seat accommodating space; the movable sliding seat can be arranged in the movable sliding seat accommodating space in an up-down sliding mode; the upper end of the movable elastic pin is inserted into the other end of the lower surface of the measuring plate, and the lower end of the movable elastic pin is inserted into the movable sliding seat and the connecting plate; and a detection head of the dial indicator abuts against the upper end of the movable elastic pin. The cylinder cover top surface auxiliary hole pitch measuring tool improves the production efficiency while improving the detection accuracy.

Description

technical field [0001] The invention relates to the field of engines, in particular to a tool for measuring the distance between technical holes on the top surface of a cylinder head. Background technique [0002] During the processing of the cylinder head, it is necessary to drill and ream two pin holes on the top surface, which is convenient for subsequent processes to use the pin holes on the top surface for positioning and processing the rest. The distance between the pinholes on the two top surfaces requires high precision, so that the subsequent use of the pinholes for positioning is accurate and there is no deviation in the position. In the process of implementing the three-inspection system, in order to accurately and quickly measure the center distance between the two pin holes on the top surface, and avoid batch failures that are not detected in time, simple and suitable measuring tools are required. The vernier calipers currently used in the production site have ...

AI Technical Summary

Problems solved by technology

The vernier calipers currently used in the production site have poor accuracy and low reliability. The three-coordinate measurement takes a long time, and the data cannot be obtained in time, and the on-site production cannot be effectively guided in a timely manner, which has greatly affected the quality judgment and production efficiency of the machining production process.
