Description

Umbrella-shaped tool magazine structure of processing machine tool

Technical Field

The utility model relates to a machine tool technical field specifically is an umbrella type tool magazine structure of machine tool.

Background

The umbrella type tool magazine used in the industry at present adopts a planetary reducer to be matched with a servo motor to perform indexing positioning, and after the umbrella type tool magazine is used for a long time, the indexing position is inaccurate after the tool is collided, the tool shank can be damaged after the umbrella type tool magazine is used for a long time, a series of reactions can be generated, the processing precision of products is reduced, and defective products are increased. For example, 12 cutter capacities of a cutter magazine are divided into 12 equal parts at 360 degrees, the cutter positions are numbered in a sequence of 1-20, after the cutter magazine is used for a long time, any one cutter needs to be adjusted to replace the cutter on the main shaft, an angle error occurs, the cutter is not concentric with the main shaft, the cutter is changed for a long time, the cutter handle is deflected, the most serious problem is that the main shaft conical hole is abraded, the main shaft conical hole needs to be abraded, the maintenance cost of a common mechanical main shaft is about 3000 yuan, the maintenance cost of an imported electric main shaft is at least ten thousand yuan once, an imported supplier needs to maintain the electric main shaft on an installed machine, and the machine tool is in a standby state in the period. The tool claw material of the tool magazine is polyoxymethylene, the material is fast in abrasion, the main shaft can shake when the main shaft is used for replacing a tool feeding handle, and the handle is different from the tool claw. The ageing is also relatively fast, and basically no tool claws are arranged on the tool magazine after the tool magazine is used for one year, so that an umbrella-shaped tool magazine structure of a processing machine tool is provided.
