Description

Technical Field

[0001] The utility model relates to the field of program-controlled multi-tooth indexing tables, in particular to a novel program-controlled multi-tooth indexing table. Background Art

[0002] The program-controlled multi-tooth indexing table is a precision instrument for detecting angles. It consists of two end face toothed discs with the same outer diameter, tooth shape, and tooth pitch. It can be used as an angle reference for measurement and as an indexing device for precision machining. It is widely used in the fields of mechanical processing and instrument detection. The control process of the traditional program-controlled multi-tooth indexing table is as follows: control the lifting motor to lift the upper toothed disc to a specified height to separate the upper and lower toothed discs; control the indexing motor to rotate the upper toothed disc to the target angle; control the lifting motor to drive the upper toothed disc to descend, so that the upper and lower toothed discs re-engage, and obtain the output value or measurement value of the angle.

[0003] At present, the more advanced programmable multi-tooth indexing table technology at home and abroad adopts a closed-loop control scheme. An angle sensor is installed at the end of the system transmission, that is, the upper gear disc, to feedback the real-time angle of the gear disc. However, in the specific implementation of this scheme, since the rotation and lifting actions are all completed by the upper gear disc, the lifting shaft system cannot be completely perpendicular to the gear disc plane. The sensor is installed on the upper gear disc, and when the lifting action moves with the gear disc, it will cause an angle offset. There is a deviation between the feedback angle value and the actual value, and it is easy to have faults such as top teeth, wrong teeth and stalling, resulting in a decrease in the system stability and measurement accuracy of the multi-tooth indexing table. What's more, it will cause the mechanical structure of the multi-tooth indexing table to be damaged, causing irreparable losses. In order to solve the above problems, the utility model adopts a design scheme in which the rotating gear disc only performs a rotating action and the lifting gear disc only performs a lifting action, and the rotation and lifting actions are separated into two different gear discs to complete. It not only inherits the advantages of the traditional closed-loop scheme to reduce electromagnetic interference and high measurement accuracy, but also reduces the failure rate of the programmable multi-tooth indexing table, improves stability, and reduces the accuracy loss caused by the processing technology and assembly process.
