Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a coaxiality inspection tool for a mould. Background Art

[0002] Circular runout refers to the difference between the maximum and minimum readings measured by a fixed indicator in a given direction when the measured element rotates around the reference axis. The existing method is to use a three-jaw chuck of a machine tool to fix the workpiece whose runout needs to be measured to ensure the accuracy of the reference axis, and then use a dial indicator to measure its runout value to see if it is within the tolerance standard. However, this method has a high detection cost and is not suitable for assembly line production. Therefore, we propose a mold coaxiality inspection fixture to solve the above problem.

[0010] (1) In the utility model, the user places the raw material into the placement groove, and then uses the angle adjustment mechanism to make the dial indicator and the surface of the raw material fit together. Then, the user can control the rotation of the rotating disk and the raw material to realize the inspection of the raw material, thereby reducing the inspection cost, being suitable for batch measurement on the assembly line, and greatly improving the production efficiency.

[0011] (2) In the present invention, the raw material is positioned by means of a placement groove, so that the raw material can coincide with the axis between the fixing rods after being inserted into the placement groove, thereby improving the accuracy of the measurement data of the raw material by the dial indicator.
