Description

Parallel adjustment mechanism for Y-axis main and auxiliary guide rails of workshop-type automatic three-coordinate measuring machine

Technical Field

Background

With the development of modern precision machining and manufacturing technology, the requirements of more and more products on precision are becoming stricter, and the traditional measuring methods and tools, such as: tools such as a measuring tape, a caliper, a dial indicator and the like are far from meeting the requirement of product precision measurement, and a three-coordinate measuring machine is produced in order to detect geometric figures of complex products. The three-dimensional coordinate measuring machine is a precise measuring instrument for three-dimensional dimensions, and is mainly used for detecting the dimensions, shapes and mutual positions of parts. The method is based on a three-coordinate measuring principle, namely, a measured object is placed in a measuring space of a three-coordinate measuring machine, the coordinate positions of all measuring points on the measured object are obtained through a measuring head, and the geometric size, the shape and the position of the measured object are solved through mathematical operation of measuring software according to the space coordinate values of the points, so that whether the measured product reaches the tolerance range marked by a processing drawing or not is judged.

The automatic three-coordinate measuring machine of the workshop type is mainly applied to the fields of automobiles, die checking tools, aerospace, electronics, military industry and the like.

The prior parallel adjusting mechanism for the Y-axis main and auxiliary guide rails of the automatic three-coordinate measuring machine in the workshop mainly comprises the following mechanisms:

(1) the auxiliary guide rail is directly connected with the upright post. The advantages of this connection are that the connection is stable and is not easy to shift and deform. The defect is that the automatic adjustment cannot be carried out, if the parallelism of the main guide rail and the auxiliary guide rail of the machine is not good, the machine is easy to bear force, so that the precision of the machine cannot reach a high standard, and the motion state of the machine is influenced.

(2) The upright post is connected with the sliding block in a needle roller mode. The adjusting mode has the advantages that the external force caused by the unparallel of the main guide rail and the auxiliary guide rail can be effectively adjusted, and the precision of the machine is effectively ensured. The defect is that the upright post ejector rod and the roller pin are in point contact, so that the deformation is easy to occur after a long time, and the long-term stability of the machine precision cannot be ensured.

In order to solve the technical problems, a new technical scheme is especially provided.
