Positioning adjustment mechanism

Abstract

The invention provides a positioning adjustment mechanism and relates to the field of machining. The positioning adjustment mechanism comprises a mandrel, a coarse positioning mechanism and a precisepositioning mechanism, wherein the coarse positioning mechanism is provided with an axial through hole, and the mandrel and a buffer force adjusting mechanism are arranged in the through hole; the precise positioning mechanism is installed on the coarse positioning mechanism in a sleeving mode and forms a micrometer-like structure together with the coarse positioning mechanism; the buffer force adjusting mechanism is connected with the mandrel and used for buffering pressure impact caused by stop of a target tool; and the coarse positioning mechanism roughly presets the forwarding or stop position of the target tool, and the precise positioning mechanism further adjusts the position of the target tool precisely by precisely positioning and adjusting differential motion of a thread on a dial according to the position of the coarse positioning mechanism. The positioning adjustment mechanism is simple in structure and convenient to operate, impact pressure of loads is effectively buffered, and in the process that the target tool is stopped and positioned, precise positioning and accurate reading are achieved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a precise positioning adjustment mechanism capable of recording numerical values. Background technique [0002] At present, in the adjustment process of equipment and tooling in many fields such as desktop lathes, processing equipment, automation equipment, tooling mechanism positioning, etc., stop, jacking screw, tip, profiling, or measurement while adjusting, there are many automation equipment It is completely adjusted by experience and feel. The problem caused by the above phenomena is that the position is not accurate, and the products produced by different people adjusting the same equipment and the same tooling are not the same, and accurate laser measurement is only a measurement method, which cannot achieve stop. Effects, such as high precision of micrometer, but not resistant to impact and heavy load; products with buffer plus gear stop, whether it is oil pressure b...

Problems solved by technology

[0002] At present, in the adjustment process of equipment and tooling in many fields such as desktop lathes, processing equipment, automation equipment, tooling mechanism positioning, etc., stop, jacking screw, tip, profiling, or measurement while adjusting, there are many automation equipment It is completely adjusted by experience and feel. The problem caused by the above phenomena is that the position is not accurate, and the products produced by different people adjusting the same equipment and the same tooling are not the same, and accurate laser measurement is only a measurement method, which cannot achieve stop. Effects, such as high precision of micrometer, but not resistant to impact and heavy load; products with buffer plus gear stop, whether it is oil pressure buffer or spring buffer, including brands such as festo, smc and srk, cannot be adjusted accurately and record data. It caused a lot of inconvenience and unstable tooling positioning to the equipment adjustment and the people who took over the equipment later.

[0003] In the prior art, micrometer knobs are mostly used, but they are not resistant to pressure shocks in production, and the purchase cost is high
