Problems solved by technology

However, in several years of practice, we have found that it is difficult to arrange internal cooling pipes on the machine tool, and we have to use external cooling for processing; Gas jet cutting often affects the operation due to the interference of nozzles or pipes, and the cooling effect is not ideal. Switching to internal cooling processing has the following problems:
[0006] ●Because there is no heat preservation measure, the temperature loss is very serious when the low-temperature gas passes through the tool table, cutter head, and tool seat to the tool;
[0007] ●In order to reduce the temperature loss, the cold air duct is directly hard-connected with the nozzle near the cutting tool, and the heat preservation problem can be better solved; but when the tool is changed during processing, the cold air duct must be removed, and after the multi-angle cutter head is rotated , and then re-insert, very inconvenient

Embodiment Construction

[0014] Figure 1 , is a kind of implementation plan of the low-temperature fluid conveying device that the cutter head is connected automatically. It can be seen from the figure that a transition connection seat 3 is provided on the lathe tool table 4, and a hollow elastic joint made of thermal insulation material is provided on the transition connection seat 3. Sleeve 5; one end of the hollow elastic sleeve 5 communicates with the cooling medium supply system with heat preservation measures; a spring 7 is installed inside it, so that the other end is close to the working state on the polygonal cutter head 1 under the action of elasticity The inlet end 2 of the fluid passage forms a fluid passage connected to the cooling medium supply system with heat preservation measures; when the cutter head 1 is rotated, the hollow elastic sleeve 5 automatically retracts, and the cone at the front end exits from the cone hole on the inlet end 2 After the indexing is completed, the taper hol...

Abstract

An automatic butt connection mechanism for capstan and low-temp fluid delivering unit features that an insulating elastic sleeve tube is used between the cooling medium supplying system and the one of the fluid inlets on polygonal capstan. When said polygonal capstan ais turned by an angle, said elastic sleeve tube can be automatically withdrawn and then connected with another fluid inlet in working state.

Description

Technical field: [0001] The invention relates to a cutter head self-connecting low-temperature fluid delivery device, which is related to metal cutting processing technology and is mainly used for low-temperature cooling of the cutting point of a lathe to provide low-temperature cooling medium to the working tool position of an indexable multi-angle cutter head. Purpose. Background technique: [0002] Existing lathes, especially CNC lathes, mostly use indexable multi-angle cutterheads, generally with 6 to 8 tool installation positions. During cutting, in order to cool the tool, it is often necessary to inject coolant into the cutting area; usually, this work is done by direct spraying through external pipes. With the advancement of technology, the cooling method of injecting oil from the inside to the outside through the tool with holes has matured. This method is called internal cooling. As a result, internally cooled drills, internally cooled milling cutters, internally ...
