Abstract

The invention relates to a tool structure for measuring plunger bottom clearance groove depths. The tool structure comprises a base, a first assembling unit and a measuring unit, wherein the first assembling unit is perpendicular to the measuring unit. Second assembling units are further arranged on the base relative to the first assembling unit at intervals. The tool structure is simple and convenient to install, the first assembling unit and the second assembling units are utilized to effectively achieve horizontal positioning of plungers, standard positioning of the plungers is achieved by arranging flat position columns, accuracy in plunger bottom clearance groove measurement is guaranteed, and the tool structure is flexible and convenient to adjust and effectively achieves depth measurement of massive plunger bottom clearance grooves of different sizes.

Description

technical field [0001] The invention relates to a tooling structure, in particular to a tooling structure for measuring the depth of a top clearance groove of a plunger. Background technique [0002] The plunger couple is formed by the precision fit of the plunger and the plunger sleeve, and the oil outlet valve couple (composed of the oil outlet valve and the oil outlet valve seat) is installed above it. The plunger can be divided into different types according to the applicable fuel injection pump. Type A, Type B, Type K, Type AD, Type P, etc., to meet the needs of different diesel engines. At present, according to the requirements of product drawings, the depth of the top clearance groove at the end of the plunger needs to be measured. Due to the mass production of the plunger, the traditional measurement method using measuring tools has the problems of time-consuming, laborious and inaccurate measurement, which not only improves The human resource cost of the enterp...
