Dedicated ruler for measuring width and position of spring clamping slots of constant-speed central fork

Abstract

The invention relates to the field of measurement of mechanical parts, in particular to a dedicated ruler for measuring the width and positions of spring clamping slots of a constant-speed central fork of a four-drive automobile, which comprises a main detection ruler and an auxiliary detection ruler; the main detection ruler is provided with a main detection ruler measurement claw, and the auxiliary detection ruler is provided with an auxiliary detection ruler measurement claw; the middle of the main detection ruler measurement claw is provided with a main ruler slot, and the clamping corner of the main detection ruler measurement claw is embedded with main ruler alloy; and the middle of the auxiliary detection ruler measurement claw is provided with an auxiliary ruler slot, and the clamping corner of the main detection ruler measurement claw is embedded with auxiliary ruler alloy. Compared with the existing caliper, the dedicated ruler disclosed by the invention has the following advantages that: the dedicated ruler is a convenient and accurate measurement tool; and 2 in the invention, the main detection ruler measurement claw and the auxiliary detection ruler measurement claw are respectively provided with the slot, so that dimension of the spring slot which is concaved in the plane can be measured, the clamping corners are embedded with the alloy which is more wear resistant than a steel material, the service life is long, and the measurement is more accurate.

Description

technical field [0001] The invention relates to the field of mechanical parts measurement, in particular to a measuring device ruler for measuring the width and position of the constant velocity center fork bullet slot of a four-drive automobile. Background technique [0002] At present, the constant velocity center fork of four-wheel drive vehicles is a new type of auto parts. It is very important to measure the machining accuracy of this new type of auto parts. The qualified machining accuracy can ensure the accuracy and reliability of the constant velocity center fork parts of four drive vehicles. sex. However, due to the limitations of its existing measuring tools, it is impossible to measure the width and position of the spring slots on both sides of the constant velocity center fork of a four-wheel drive vehicle very accurately, especially because the upper part of this part is a spherical shape that can rotate in 360 degrees.

Problems solved by technology

However, due to the limitations of its existing measuring tools, it is impossible to measure the width and position of the spring slots on both sides of the constant velocity center fork of a four-wheel drive vehicle very accurately, especially because the top of this part is a spherical shape that can rotate in 360 degrees. The inner sleeve cannot be fixed to measure its position, and the general caliper cannot measure this structural size, and the existing measurement methods cannot meet the strict requirements of the machining accuracy of the parts

The existing relatively common measurement techniques are ordinary calipers and instruments. The most advanced measurement should be a three-coordinate measuring instrument, but these measurements cannot meet the requirements of the assembly height of the constant velocity center fork assembly of a four-wheel drive vehicle. The measurement is accurate, fast, and 100% Inspection requirements, in addition, the cost of three-coordinate measurement is very high, the total cost of measuring small parts cannot be greater than the processing cost, otherwise the gain outweighs the loss
