Description

  The present invention relates to the field of rotating tool sockets.

  Conventionally, as a rotary tool socket, Japanese Patent Laid-Open No. 2006-175523 (A) has been disclosed. This rotary tool socket has a shaft fitting hole (1a) into which a shaft member (2) is fitted and fixed. The shaft member (2) is fitted and fixed in the shaft portion fitting hole (1a) by changing the diameter of the shaft member at the front and rear ends.

Therefore, the tightening allowance after the shaft member (2) is fixed by fitting is set and fixed so as to be small at the rear end side of the shaft portion fitting hole (1a) and large at the front end side.

Therefore, since the length of the shaft portion fitting hole (1a) for fitting and fixing the shaft member (2) is shortened, the shaft member (2) may be easily broken during the rotation operation.

  Further, the shaft member (2) of the socket for a rotary tool disclosed in the disclosed published patent application (A) has a small rear end side of the shaft portion fitting hole (1a) and a large tightening margin on the front end side. As a result, there was a risk that the socket would shake during the rotating operation of the tool.

In addition, the socket for a rotary tool disclosed in the above-disclosure published patent application (A) is designed to fix the length of the fitting portion of the shaft member (2) in consideration of an allowance for fitting and fixing the shaft member (2). Therefore, the length protruding from the socket member (1) is shortened, and there is a drawback that it is easy to break.
Japanese Patent Laid-Open No. 2006-175523 (A)

  However, the problem to be solved by the present invention is that the shaft fitting hole portion and the shaft fitting hole portion in the socket member are fixed to the shaft fitting hole portion. And the large-diameter shaft fitting hole portion, the shaft fitting hole portion, and the outer portion of the front end portion of the socket member is pressed to the extent that there is no gap, and the shaft portion is fixed. The projecting length of the tool was increased and the rattling of the rotary tool was eliminated.

  Further, in the rotary tool socket according to the present invention, since the fitting and fixing portion of the shaft portion is the two locations of the shaft fitting hole portion and the outer portion of the front end portion of the socket member, Inside, the blurring phenomenon was prevented in advance, and the above-mentioned shaking was prevented so that the shaft portion of the socket would not cause metal fatigue and breakage.

  Further, the present invention provides a durability of the rotary tool by forming a gap with a predetermined width between the outer surface of the shaft portion to be fitted and fixed in the shaft fitting hole portion and the large-diameter shaft fitting hole portion. Sexually increased.

  As a means for solving the problem, the invention according to claim 1 is directed to a rotary tool socket a including a socket member 1 and a shaft portion 2 fitted and fixed to the socket member 1, in the axial direction of the socket member 1. An opening fitting portion 3 is provided at the rear end 1b of the socket member in the axial direction from the opening fitting portion 3, and a hollow hole portion 4 is provided at the center of the flange of the socket member 1, so that the hollow hole portion 4 is extended. A shaft fitting hole portion 5 having a circular longitudinal cross-section in which one end portion of the shaft portion 2 is fitted to the socket member 1 between the front end portion 1a in the coaxial direction and the shaft fitting hole portion 5 A large-diameter shaft fitting insertion hole 6 having a circular longitudinal section with a larger inner diameter is sequentially extended toward the front end 1a, and the shaft portion 2 is extended from the large-diameter shaft fitting insertion hole 6 to the shaft. The shaft portion 2 is inserted into the inner side surface portion 5a of the fitting hole portion 5 so that the outer peripheral corner portion 2a of the shaft portion 2 is engulfed. While being fixedly fitted into the hole 5, the shaft 2 that is inserted into the large-diameter shaft fitting insertion hole 6 is pressed so that the front end 1a of the socket member 1 does not rattle from the outside. A rotary tool socket that is fixed and forms a gap 7 having a width that does not contact the outer peripheral corner 2a of the shaft 2 between the shaft 2 and the large-diameter shaft fitting insertion hole 6. .

  As means for solving the problems, the invention according to claim 2 is a rotary tool socket in which the shaft portion 2 to be inserted into the shaft fitting hole portion 5 has a hexagonal shape.

  As a means for solving the problem, the invention according to claim 3 is characterized in that the gap portion 7 has a uniform width between the large-diameter shaft insertion portion 6 and the outer peripheral corner portion 2a of the shaft portion 2. This is a tool socket.

  The invention described in claim 1 is a rotary tool socket a comprising a socket member 1 and a shaft portion 2 fitted and fixed to the socket member 1. The joint portion 3 is set in the axial direction from the opening-shaped fitting portion 3, and a hollow hole portion 4 extends in the center of the flange of the socket member 1, and the front end portion 1 a coaxial with the hollow hole portion 4 The socket member 1 in between is fitted with a shaft fitting hole portion 5 having a circular longitudinal section in which one end portion of the shaft portion 2 is fitted, and a circular longitudinal section having a larger inner diameter than the shaft fitting hole portion 5. The large-diameter shaft fitting insertion hole 6 is sequentially extended toward the front end 1a, and the shaft portion 2 is extended from the large-diameter shaft fitting insertion hole 6 to the inner side surface portion of the shaft fitting hole 5. 5a is inserted into the outer peripheral corner 2a of the shaft 2 so that the shaft 2 fits and is fixed to the shaft fitting hole 5. The shaft portion 2 to be inserted into the large-diameter shaft insertion hole portion 6 is pressed and fixed to such an extent that the front end portion 1a of the socket member 1 does not rattle from the outside. Since this is a rotary tool socket in which a gap 7 having a width that does not come into contact with the outer peripheral corner 2a of the shaft 2 is formed between the shaft-inserting hole 6 and the outer peripheral portion 2a of the shaft. The inner surface portion 5a of the portion 5 is caught and fixed, and is pressed and fixed to the extent that the front end portion 1a of the socket member 1 does not rattle. The shaft portion 2 has an advantage that it does not cause a shaking phenomenon during work.

Further, the present invention has an advantage of eliminating the possibility of breakage during the rotating operation because the shaft portion is projected longer than the end portion of the socket member.

The invention according to claim 2 has the same effect as the effect of the invention according to claim 1 because the shaft part 2 to be inserted into the shaft fitting hole part 5 is a hexagonal rotary tool socket. is doing.

In the invention according to claim 3, the gap 7 is a rotary tool socket having a uniform width between the large-diameter shaft fitting insertion portion 6 and the outer peripheral corner portion 2a of the shaft portion 2. Or it has the same effect as the effect of the device of the said 2 description.
