Special cylinder oblique oil hole angle detecting tool

Abstract

The invention discloses a special cylinder oblique oil hole angle detecting tool which comprises a measuring tool, adjusting bolts, a detecting bar, a spring and a steel ball. The measuring tool comprises two same protractors and a connecting piece, two ends of the connecting piece are connected with the two protractors, the detecting bar is arranged between the two protractors and rotatably connected with the protractors through the adjusting bolts, the adjusting bolts are coaxially arranged at center dots of the protractors, a positioning hole is formed in the lower end of the detecting bar,one end of the spring is fixed at the bottom of the positioning hole, the other end of the spring is fixedly connected with the steel ball, a recessed pointer is fixed onto the upper end of the detecting bar and provided with two inverted triangle sides, and inverted triangle apexes point to scales on the protractors, wherein the scales indicate angles formed by the detecting bar. The detecting tool has the advantages of simple structure, high measuring accuracy and measuring efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of engine accessory assembly, in particular to a special inspection tool for detecting the angle of an oblique oil hole in a cylinder block. Background technique [0002] The machining of the oblique oil hole in the engine cylinder block is generally completed by machining equipment. Due to the irregular shape of the engine cylinder block, it brings difficulties to the processing work after machining. At present, there is no special measurement and inspection tool for the angle of the inclined oil hole in the cylinder block, and the processing quality monitoring can only rely on the three-coordinate inspection for processing control. In the event of equipment maintenance and tooling adjustment during the inspection, it is necessary to send the debugged equipment to pass the inspection before normal production. This process seriously affects the production progress, resulting in waste of time waiting and low ...

[0002] The machining of the oblique oil hole of the engine cylinder block is generally completed by machining equipment. Due to the irregular shape of the engine cylinder block, it brings difficulties to the processing work after machining

At present, there is no special measurement and inspection tool for the angle of the inclined oil hole in the cylinder block, and the processing quality monitoring can only rely on the three-coordinate inspection for processing control. In the case of equipment maintenance, tooling adjustment, etc. during the inspection, it is necessary to send the debugged equipment to pass the inspection before normal production. This process seriously affects the production progress, resulting in waste of time and low work efficiency.

Moreover, the inspection frequency of the engine cylinder block is once a week, and the inspection frequency is high. Due to reasons such as the maintenance and debugging of the three-coordinate inspection equipment, the product cannot be inspected in time, the quality monitoring of the product processing process is lacking, and there are hidden dangers of uncontrolled processing. Failure to produce batches of unqualified products in time
