Description

  The utility model relates to a machine tool, and more particularly, to an adapter that can prevent a pipe for cutting fluid from being exposed.

Please refer to FIG. 4, FIG. 5, and FIG. A tool storage assembly 80 used for a lathe includes a rotary tool changer 81, a fixed seat 82, an adapter 83, a cutter holder 84, a cutter 85, and a conduction pipe 86.
The fixed seat 82 is assembled to the rotary tool changer 81. Each of the rotary tool changer 81 and the fixed seat 82 has an inner pipe. The rotary tool changer 81 and the fixed seat 82 communicate with each other via these inner pipes. The adapter 83 is a sleeve having a joint portion 831 and a contact portion 832. The joint portion 831 has an outer diameter, and has a fastening bolt through hole 8311 that penetrates the joint portion 831 and is defined in the axial direction. The contact portion 832 is connected to the joint portion 831 in the axial direction, has an outer diameter, and has a cutter holder through hole 8321 and a connection hole 8322.
The cutter holder through-hole 8321 is defined by penetrating the contact portion 832 and communicates with the fastening bolt through-hole 8311 in the axial direction. The connection hole 8322 is defined in the contact portion 832 in the radial direction of the contact portion 832, and communicates with the cutter holder through hole 8321. The outer diameter of the contact portion 832 is larger than the outer diameter of the joint portion 831. The adapter 83 is attached to the fixed seat 82. The cutter holder 84 is mounted in the cutter holder through hole 8321 of the adapter 83. The cutter 85 is mounted in the cutter holder 84. Since the conduction pipe 86 is connected to the connection hole 8322 between the adapter 83 and the fixed seat 82, the fixed seat 82 and the adapter 83 are connected to each other via the conduction pipe 86.

  The cutting fluid supplied by the rotary tool changer 81 is guided into the fixed seat 82 by the inner pipe and then guided into the adapter 83 through the conduction pipe 86. The cutting fluid in the adapter 83 is guided into the cutter holder 84 and then discharged from the two spiral channels defined in the cutter 85 to lubricate and cool the cutter 85.

  The cutting fluid is guided into the conventional adapter 83 through the conduction pipe 86 attached to the connection hole 8322. Since the cutting fluid is guided by the exposed conductive pipe 86, the exposed conductive pipe 86 may be easily damaged due to a situation in which debris is blown off in the cutting process. In addition, the conduction pipe 86 is easily detached from the fixed seat 82 or the adapter 83 when the hydraulic pressure of the cutting fluid is too high. Further, the conduction pipe 86 located outside may collide with other parts of the tool storage assembly 80 during the operation of the rotary tool changer 81.

  In order to overcome the disadvantages of conventional adapters, the utility model provides a water pressure resistant adapter to alleviate or avoid the above problems.

  The main purpose of this utility model is to provide a water pressure resistant adapter that can withstand high water pressure.

  The adapter has a joint portion and a contact portion, and the contact portion is connected to the joint portion in the axial direction. The joint has an outer surface, a conductive recess, and an inlet hole. The conducting recess is defined on the outer surface of the joint and has a lower surface. The inlet hole is defined through the lower surface. In order to assemble the cutter holder, the abutting portion has a cutter holder through-hole defined through the abutting portion. An adapter can be used for a tool storage part, and a tool storage part has a rotary exchange part which supplies cutting fluid. Due to the presence of the concavity and inlet hole defined in the adapter, the exposed pipe may come off when the hydraulic pressure of the cutting fluid is too high, the problem that it will be easily damaged by debris, and the tool storage is in operation All the problems of easily colliding with other components can be solved.
