Problems solved by technology

[0002] A certain type of cabin is a circular part. During the assembly process, the requirements for the assembly of the two components, the dropout socket and the end switch, are high, and the measurement accuracy of the position and size after assembly is high. These dimensions are based on the horizontal position of the cabin. The highest point on the surface of the cabin (i.e. the point on the line of symmetry) is the mea

Example Embodiment

[0013] Hereinafter, the present invention will be further described with reference to the drawings and specific embodiments.

[0014] Such as figure 1 , 2 As shown, in this embodiment, it is a piece of assembly size measurement tool, which includes: a measuring base 1, a positioning glass plate 2 embedded in the measuring base, and a positioning pin 3 mounted on the measuring base, The self-checking board 4 installed on the measuring base is distributed with measuring holes 5, 6, 7, observation holes 8, and sample columns 9.

[0015] The measurement base 1 is L-shaped, the bottom surface is a curved surface, and the arc is the same as that of the cabin body, which can ensure that the measurement base 1 fits the cabin body when placed on the outer surface of the cabin. The top surface of the measurement base 1 is a flat surface along the cabin. The horizontal plane where the measurement reference point on the body is located moves parallel, and the top surface is kept in the horizon...

Abstract

The invention provides a tool for measuring an assembly size of a finished part. The tool is used for measuring the size of a finished part of a circular cabin body,and comprises a measuring base,a self-checking plate and a detection sample column,wherein the bottom face of the measuring base is a cambered surface matched with the camber of the cabin body,the measuring base is used for fitting thesurface of the cabin body during measurement,the top face of the measuring base is located in a flat when the tool is located in a measuring position; a measuring hole cooperating with a to-be-measured portion is formed in the measuring base; the detection sample column can be located in the to-be-measured portion through the measuring hole; the self-checking plate at the side of the measuring hole is rotationally arranged on the measuring base,is an assembly produced according to a go-no go fixed gauge principle,and can quickly detect whether or not the size of the to-be-measured portion iswithin a tolerance range through the cooperation with the detection sample column. The tool for measuring assembly sizes of finished parts improves the measurement efficiency and measurement result reliability of the measurement,thereby improving the assembly efficiency of the finished part.

Description

technical field [0001] The invention belongs to the technical field of measurement, and relates to a measuring tool for component assembly dimensions, in particular to a tool for measuring component assembly dimensions of a circular cabin body. Background technique [0002] A certain type of cabin is a circular part. During the assembly process, the requirements for the assembly of the two components, the dropout socket and the end switch, are high, and the measurement accuracy of the position and size after assembly is high. These dimensions are based on the horizontal position of the cabin. The highest point on the surface of the cabin (i.e. the point on the line of symmetry) is the measurement reference. Because the installation position of the end switch is located on one side of the cabin, it cannot be directly measured with a depth gauge. The general measurement method is: hoist the cabin to After leveling the cabin, multiple measurements are performed, and finally the...
