Problems solved by technology

[0004] For gaskets of different specifications, people have previously used tools such as vernier calipers and micrometers for manual measurement. However, due to factors such as burrs, reverse edges, and uneven thickness of the gasket itself, the measurement error is often large.

Embodiment Construction

[0015] Referring to the accompanying drawings, the present embodiment is provided with a splint-shaped measuring head. The splint-shaped measuring head is composed of a bottom measuring platform 8 and a measuring platen 9 above the measuring platform 8. The gasket is placed between the measuring platform 8 and the measuring platen 9. The measuring platform 8 is an axially moving member, and the shaft-shift measuring rod 12 is arranged along the axial direction of the measuring platen 9. The measuring head of the dial indicator 14 is against the top end face of the shaft-shift measuring rod 12, and the bottom end face of the shaft-shift measuring rod 12 extends toward the measurement The platform 8 is accessible to the measurement platform 8, and the axis displacement measuring rod 12 uses the measurement platform 8 as a sensing surface.

[0016] As shown in the figure, in this embodiment, the axial movement of the measurement platform 8 adopts a pneumatic control method, and an...

Abstract

An apparatus for measuring the width of distance piece has a characteristic that a gauge pin is installed. The gauge pin is consisted of measuring plate at the bottom and meaning above the plate. The distance piece to be measured is between the measuring plate and measuring plate. The measuring plate is axial moving component, the axial moving measuring stick. Being driven with the measuring head of dial gage is installed along the axial direction of measuring , the axial moving measuring stick makes the measuring plate. The invention has simple structure and practical use, high accuracy of distance piece width measurement and measuring efficiency.

Description

Technical field: [0001] The present invention relates to measuring devices, more particularly to a thickness measuring device. Background technique: [0002] The car drive axle is an important large assembly of the car. It is located at the end of the car drive train. Its basic function is to increase the torque transmitted from the drive shaft or directly from the transmission, distribute it to the left and right drive wheels, and make it The left and right drive wheels have the differential function required by the driving kinematics of the car; at the same time, they bear the full sprung load of the car and the vertical force, longitudinal force, Lateral forces and their moments, as well as impact loads. In a general automobile structure, the drive axle includes components such as the final reducer, the differential, the transmission device that drives the wheels, and the axle housing. Among them, the function of the main reducer is to further decelerate the power of th...
