Abstract

The present invention provides a cooling liquid conveying apparatus having a ball-and-socket connecting structure. The socket has a through hole along its axial direction, and the through hole communicates with a ball-shaped hole formed in an upper portion of the socket. The O-ring for airtightness is provided in an annular undercut formed at the bottom portion of the inner edge of the ball-shaped hole, and the O-ring for fixing is assembled to the upper end of the ball-shaped hole. The spray head is integrally coupled to an upper ball base and a lower ball base, which can rotate around a plurality of axes. Therefore, the direction of the nozzle protruding outward from the upper ball can be adjusted to a predetermined angle by the rotation operation of the lower ball base in the ball-like hole so that the cooling liquid discharged to the outside of the nozzle can accurately aim the target zone.

Description

Technical Field [0001] The present invention relates to a COOLANT DELIVERY DEVICE FOR CUTTING TOOLS,

The present invention relates to a coolant delivery device for a cutting tool, and more particularly, to a new coolant delivery device for a cutting tool that enables orientation of a coolant nozzle at a certain angle so that the coolant discharged from the nozzle can aim at the target zone .

In general, various cutting tools for metal working and machining processes are sometimes equipped with a spray head for conveying the cutting fluid to the interface between the cutting tools and the workpiece. Latches are the most important machine in the industry and widely used in the industry because they can be applied to various materials processing as well as having various cutting functions. With the constant improvement of latches, the production of products has become more sophisticated. The tools used in the latches are often referred to as latching tools, which are typically mounted on tool holders, and the tools are forced to contact the workpieces when the latch is in operation. Latch tools can be easily exchanged for maintenance and production purposes.

Metal cutting operations, which are performed by conventional latches, sometimes generate heat due to friction between tools and workpieces at high rotational speeds. In order to protect the cutting tools from wear and to protect the workpieces from deformation due to overheating, the spray heads are sometimes used to transport the cutting fluid to the interface between the tools and the workpieces.

Conventional spray heads for delivering coolant can achieve predicted results with regard to transporting the coolant fluid to the interface between the tools and the workpieces, but there is a limit on the spray angle of the coolant carried from the spray heads Found out in the implementation process. This causes a great inconvenience during the operation. Therefore, there is still room for further improvement in the overall implementation of the spray head.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

FIG. 1 is a schematic exploded perspective view showing the structure of the present invention, FIG. 2 is a schematic assembled perspective view showing the structure of the present invention, and FIG. 3 is a schematic assembled sectional view showing the structure of the present invention. As shown in the drawings, the coolant delivery device for a cutting tool of the present invention includes a socket 1 and a spraying head 2.

The socket (1) has a threaded portion (11) provided at its bottom portion for threaded engagement and is thus fixed in a predetermined position. The socket 1 has a through hole 12 along the axial direction thereof and the through hole communicates with the ball hole 13 formed in the upper portion of the socket 1. [ The airtight O-ring 14 is provided in an annular undercut 131 formed at the bottom of the inner edge of the ball-shaped hole 13, And assembled at the upper end.

The spray head 2 is integrally joined with an upper ball base 22 and a lower ball base 21 placed in the ball hole 13 of the socket 1. [ A conduit 23 coinciding with the through hole 12 of the socket 1 and communicating therewith is formed in the upper ball base 22 and the lower ball base 21 and has a nozzle 24 communicating with the conduit 23, Is provided protruding outward from the upper ball base 22. Also, the conduit 23 of the spray head 2 is connected at an angle of 10 to 90 with the nozzle 24 as shown in FIG.

The practice of the present invention will be described with reference to a schematic cross-sectional view of FIG. 5 showing an implementation state of the present invention. The O-ring 14 for airtightness is placed in the annular undercut 131 formed in the ball forming hole 13 of the socket 1 and then the lower ball base 21 of the spraying head 2 is inserted into the ball- 13). Thereafter, the fixing O-ring 14 is assembled to the upper end of the ball-shaped hole 13 so that the lower ball base 21 can not be detached in the ball-like hole 13. In this way, the coolant delivery device for a cutting tool of the present invention can be installed to engage with a cutting tool on a tool holder. 6 is a schematic diagram showing an assembled state for the implementation of the present invention. According to this figure, the threaded portion 11 of the socket 1 is screwed into a suitable position on the air holder 3 for firmly securing the socket 1 to the tool holder 3. The lower ball base 21 of the spraying head 2 rotates within the ball-shaped hole 13 so that the nozzle 24 of the spraying head 2 can aim at the interface between the tool and the workpiece, . In operation, the cooling fluid exiting the through-hole 12 through the conduit 23 of the spray head 2 to the nozzle 24 is discharged to the interface between the tool and the workpiece. Since the spray head 2 is an integral coupling between the upper ball base 22 and the lower ball base 21, the tilting direction of the nozzle 24 is controlled by the operation of the lower ball base 21 in the ball- And can be adjusted to a predetermined angle. The conduit 23 of the spray head 2 is also connected to the nozzle 24 at an angle of 10 to 90 degrees so that the cooling fluid is supplied by the nozzle 24 of the spray head 2, It can be more accurately sprayed on the interface between the objects. The coolant delivery device can be adjusted for use with various types of cutting tools with better cooling effect and long life of the cutting tools.

Further, the threaded portion 11 located at the bottom portion of the socket 1 according to the present invention can be fitted to the other threaded portion. Therefore, for this purpose, a connecting portion 111 is provided on the upper portion of the screw portion 11. [ Alternatively, the threaded portion 11 may be an integral structure more suitable for this purpose, as shown in Fig.

Based on the above description of the structural construction and implementation of the present invention, the tilting direction of the nozzle is such that the lower ball base in the ball-like hole has a 360 ° angle from the front to the rear and a 35 ° to 180 ° angle As shown in FIG. In addition, the coolant delivery device can be adapted for use in various types of cutting tools, for example, triangular, diamond-like, circular cutting tools, so that the cooling fluid can flow through the nozzles of the spray head, It can be more accurately sprayed to the interface.

The foregoing description of the embodiments of the present invention is intended to be illustrative, not limiting. Variations and modifications made without departing from the spirit and scope of the present invention are still considered to be within the scope of the present invention.
