How to conduct static test on precision nc lathe?

Vertical hob accuracy inspection: first, the numerical control instrument lathe equipment in the indexing ring, adjust the indexing chain, so that the number of index teeth and index worm teeth equal.Z. Install gauge plate on spindle of hob and add reading on column.The microreflector is used to determine the rotation of the standard indexing disk (i.e., the spindle of the hob).Full automatic CNC lathe equipment supply in the work table installation transverse instrument (or optical goniometer), in the work machine frame installation collimator (that is, parallel light tube), in the distance hanging a scale line, can determine the rotation of the work table.

RotationPOV.The spindle of the hob rotates once, and the table theoretically rotates 360°/z in worm gear. The spindle of the hob rotates once each time, returning to its original position through the transverse instrument, so that the viewpoint can rotate.The operation of the table forward rotation and reverse each check once, the practice of the operation table rotation view and the theoretical rotation view difference, is the mechanical indexing chain part of the degree transmission error.At the edge of the workspace.How to measure the transmission error of rolling disc?A: like the test insert machine, the transmission of the rotary disc supplied by ningbo precision CNC lathe is different in rotating principle.Wrong measurement.

Adjustment of hob's hob shaft?How to check the static inspection of nc lathe?The axis of the table is flat.The invention relates to a collision circular plate with a device arranged on a hob shaft, a fixed disc of the umbrella rod is arranged on a concentric device on the operating automatic ball head table, and a collision collision is located on the umbrella rod.

The diameter ratio of the two colliding disks is equal to the path movement ratio between the hob shaft and the base supplied by taizhou precision CNC lathe.When the colliding plate is rotated, the colliding plate is rolled by the colliding force and forms the colliding head.Comparative organization of sampling.If there is no transmission error from the hob shaft to the work cabin transmission chain, the collision plate and the fixing plate can be reversed synchronously, but the transmission is generated between the transmission chain.
