Device for measuring mouth inside diameter of three-cylinder pot shell

Abstract

The invention discloses a device for measuring the mouth inside diameter of a three-cylinder pot shell, comprising a three-cylinder pot shell and a cylindrical measuring block. The mouth on the inner wall of the three-cylinder pot shell is a slope; an axial through hole is arranged in the middle part of the cylindrical measuring block; the outer side wall of the cylindrical measuring block is a conical surface; the cylindrical measuring block is arranged in the mouth of the three-cylinder pot shell; the outer side wall of the cylindrical measuring block is attached to the inner wall of the three-cylinder pot shell; the point where the cylindrical measuring block contacts the mouth of the three-cylinder pot shell is a positioning point; and a measuring point is arranged in the mouth of the three-cylinder pot shell opposite to the positioning point. The invention has simple structure; as the cylindrical measuring block is arranged in the mouth of the three-cylindrical pot shell, the conical surface on the outer wall of the cylindrical measuring block is inosculated with the slope on the inner wall of the three-cylinder pot shell and is used as a positioning point and the measuring point is arranged on the opposite position, the mouth inside diameter of the three-cylinder pot shell can be measured through a vernier caliper. The invention solves the problem that the traditional mouth inside diameter is difficult to measure, can be used for measurement of any specifications and has good practical value.

Description

technical field [0001] The invention relates to a device for measuring the inner diameter of the mouth of a three-column tank shell. Background technique [0002] In the transmission system of automobiles, universal joint transmissions are often used to realize power transmission between a pair of rotating shafts whose axes intersect and whose relative positions often change. The universal joint transmission device is generally mainly composed of a universal joint and a transmission shaft, and sometimes an intermediate support shaft. In the automobile transmission system, the universal joint is a relatively important component, which directly affects the working condition of the automobile transmission system, thus affecting the safety of driving, so the detection of the automobile universal joint is very important. [0003] The size of the inner diameter of the mouth of the three-column groove shell directly affects the swing angle and slippage of the inner ball cage in th...
