Description

Technical Field

[0001] The utility model relates to the field of machining tools, in particular to a tool internal cooling conversion joint. Background Art

[0002] During the metal cutting process, the work done by chip shear deformation and the work done by friction in front and behind the tool are converted into cutting heat. A large amount of cutting heat will cause the temperature of the cutting area to rise rapidly, which will not only increase tool wear and reduce tool life, but also affect the surface processing quality of the workpiece and reduce the processing efficiency of the workpiece.

[0003] Currently, there are two main ways to cool tools: one is traditional external cooling, and the other is internal cooling, that is, internally cooled tools. Traditional externally cooled tools are to install coolant nozzles on the machine tool, and spray coolant onto the cutting part of the tool through an external pressurizing device. Although this method of cooling by pouring large amounts of coolant with a flexible plastic nozzle can achieve a certain cooling effect, it often has disadvantages such as inaccurate positioning, waste of resources, and is not conducive to environmental protection. Existing internally cooled tools, although they can improve the cooling effect, have a complex system structure and require professional coolant delivery pipelines, which increases equipment cost and maintenance difficulty. Utility Model Content

[0004] The purpose of the utility model is to provide a tool internal cooling conversion joint, which solves the technical problems pointed out in the background art that the existing internal cooling tool system is complex, costly and inconvenient to maintain.

[0005] To achieve the above-mentioned purpose, the utility model provides a tool internal cooling conversion joint, including a joint body and a clamping sleeve, the joint body having an inlet end and an outlet end, the clamping sleeve being connected to the outlet end of the joint body, and the clamping sleeve being radially provided with a locking piece, and the locking piece can move radially within the clamping sleeve.

[0006] Furthermore, a sealing member is provided between the joint body and the clamping sleeve.

[0007] Furthermore, the locking member is a machine screw.

[0008] Compared with existing technologies, the present invention offers the advantage of direct cooling of the tool's cutting edge and heat-generating areas, achieving precise and efficient cooling. This significantly improves the cooling effect, effectively lowers tool temperature, extends tool life, and reduces tool wear and damage due to overheating. The overall structure is simple, making replacement and maintenance easy and widely applicable. BRIEF DESCRIPTION OF THE DRAWINGS

After the clamping sleeve 3 is connected to the joint body 1, the inlet end of the joint body 1 forms a shoulder 11 in the clamping sleeve 3.

[0021] The operating principle of this utility model is as follows: When internal cooling of a machining tool is required, the clamping sleeve 3 is threaded onto the outlet end of the connector body 1. The locking member 4 is placed in the locking hole 10 of the clamping sleeve 3. The locking member 4 is initially pre-tightened. The rear end of the clamping sleeve 3 is mounted on the already fixed internal cooling shank 5 until the end of the internal cooling shank 5 contacts the shoulder 11. The locking member 4 is tightened until the internal cooling shank 5 cannot move axially or rotate. The inlet end of the connector body 1 is then connected to the cooling device using a braided hose.

[0022] A seal 2 may be provided between the connector body 1 and the clamping sleeve 3. The seal 2 is positioned within an annular groove 6 on the rear side of the inlet end of the connector body 1. When the clamping sleeve 3 is connected to the connector body 1, the seal 2 provides a good seal between the connector body 1 and the clamping sleeve 3. The seal 2 may be made of a material such as fluororubber or nitrile rubber. The locking member 4 may be a common component such as a machine screw or a hexagon socket head cap screw, preferably a machine screw due to its low cost.

[0023] This utility model has a simple overall structure, low manufacturing cost, and easy maintenance. It can be used for tool bars with internal cooling oil circuits, such as boring tools, threading tools, and drill bits, and has a wide range of applications.
