Tool puller device applied to iso, bt, bbt, sk, cat push-pull tool system

Abstract

The invention discloses a puller device of a cutter. The puller device of the cutter is characterized in that the smallest-diameter place of the tail end of a standard push-pull knife handle segment of the cutter is correspondingly connected with a puller portion. The outer diameter of the puller portion is slightly smaller than that of the smallest-diameter place of the tail end of the standard push-pull knife handle segment. A ring groove is fixedly arranged on the outer diameter and a large-caliber through hole is arranged at the center of the puller portion. Besides, the puller portion can be integrally formed with the push-pull knife handle segment or be arranged in a split type corresponding assembly mode. Thus, the outer diameter of the puller portion of the cutter can provide the function of fastening and performs an automatic tool changing (ATC) function by combining with a knife handle interface which complies with international standard specifications. Meanwhile, functions of an assisting working machine are possessed by the puller device of the cutter so as to overcome the defect of incomplete functions of existing equipment, wherein the functions of the assisting working machine include that a large-power transmission shaft can correspondingly penetrate through the through hole of the knife can pen, air is used for blowing and cleaning, and a cutting fluid can pass through.

Description

technical field [0001] The present invention relates to a tool puller device applied to ISO, BT, BBT, SK, CAT push-pull tool systems, especially to a tool clamping puller structure for the main shaft of a machine tool, which can be combined with Existing international standard tool holders can also be used for automatic tool change (ATC) and have a larger through hole diameter for large-sized transmission shafts to pass through, as feed axes such as U-axis or machining power axis, right-angle milling The first-class power transmission is applied to the tool puller device of ISO, BT, BBT, SK, CAT push-pull tool system. Background technique [0002] Generally, the tool system of existing processing machines adopts standard 7 / 24 push-pull tools in response to mechanisms such as replacement. Please refer to Figure 1A ~ Figure 1C As shown, the reference diameters of the standard push-pull tools are the same (such as specification 7 / 24), and the main difference is the position of...

AI Technical Summary

Problems solved by technology

[0004] 1. Limited by the standard size of the slider, the diameter that can pass through the center hole is very small, only small power can be transmitted, and the function is limited

[0005] 2. The original tool center hole can pass through the function of cutting fluid, but it cannot be used

[0009] 1. The tool system and the slider device adopt the existing international standards. Although it can automatically change tools (ATC) and the existing tools can be fully utilized, it cannot provide the central water outlet function, the transmittable power is small, and the application is limited. shortcoming

[0010] 2. If a special tool system is used, either the tool cannot be changed automatically, or the tool change device needs to be redeveloped. In addition to the complicated mechanism, the old tool cannot be used as a major disadvantage. Therefore, it is only suitable for special processing machines
