Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a tool head holder that can be used in so-called tooling for attaching and detaching a tool head to and from a machine tool, particularly when the tool head is stored and transported depending on a person.

[0002]

[Prior art]

 Conventionally, this type of manual-based tooling involves the work of taking out a tool head from a storage rack and mounting it on a machine tool, and the work of removing the tool head from the machine tool and storing it in a storage unit. Since the storage rack stores many tool heads holding tools, it is often of the rack type or cabinet type that stores multiple tool heads in multiple stages and multiple rows. They are stored in a substantially vertical direction, a substantially horizontal direction, or an inclined direction. Generally, a chuck portion for connecting a tool is provided at one end of a tool head, and a shank portion which is pushed into a main shaft of a machine tool is provided at the other end. Further, a flange portion used for tooling is provided between the chuck portion and the shank portion of the tool head, and an annular groove is formed in the flange portion. The tool head is fitted in the hole of the storage rack with the tool connected to the chuck portion and the tool directed downward. When mounting a tool on a machine tool, pull out the tool head holding the tool from the storage rack, turn it over, turn the tool upward, transport it to the machine tool, and move the tool head shank to the machine tool spindle. Fit. When storing a tool in the storage rack, remove the tool head from the main spindle of the machine tool, transport the tool to the storage rack with the tool facing upward, insert the tool holder upside down into the storage rack. .

[0003]

[Problems to be solved by the invention]

 However, in conventional hand-based tooling, the tool head is inverted before the tool head is taken out of the storage rack or before being stored in the storage rack. There is also the problem of being injured.

An object of the present invention is to provide a tool head holder that can solve the above-mentioned problems, can shorten tooling time, and can prevent injury to an operator.

[0005]

[Means for Solving the Problems]

 A tool head holder according to the present invention for achieving the above object has a horizontal portion having a substantially semicircular hole for receiving a groove on an outer peripheral surface of a tool head, and a rear portion of the horizontal portion. It is characterized by comprising a vertical part raised perpendicularly and a hook part provided on the upper part of the vertical part.

[0006]

[Embodiment of the invention]

 The present invention will be described in detail based on the illustrated embodiment. FIG. 1 is a perspective view of a holder 2 according to a first embodiment holding a tool head 1, and shows a state in which the holder 2 is hooked on a rod 4 of a storage unit 3. The storage section 3 is, for example, a rack type, in which a plurality of rods 4 are arranged at intervals in the horizontal and vertical directions, and rotation of the holder 2 is prevented by the rods 4 located below. . If a plurality of rods 4 arranged in the vertical direction are provided in the storage section 3 in multiple rows in the horizontal direction, a large number of tool heads 2 can be stored in the storage section 3.

FIG. 2 is a sectional view of the holder 2 shown together with the tool head 1. The tool head 1 has a chuck portion 11 for detachably connecting a tool 10 and a groove portion 12 and is used for tooling. A flange portion 13 to be fitted, a shank portion 14 fitted to a main shaft of a machine tool (not shown), and a stud portion 15 pushed and pulled by the machine tool are sequentially provided from below.

The holder 2 is provided with a horizontal portion 21 that is held in a substantially horizontal state during tooling, and a plate-shaped vertical portion 22 that is raised substantially perpendicularly from the rear of the horizontal portion 21. Have been. A substantially semicircular hole 23 for receiving the groove 12 of the tool head 1 is formed in the horizontal portion 21, and the hole 23 is reinforced by a boss 24. At an upper end of the vertical portion 22, a hook portion 25 to be hooked on the rod 4 of the storage portion 3 is bent.

The vertical length of the vertical portion 22 of the holder 2 is slightly larger than the interval between the vertically adjacent rods 4 of the storage portion 3, and the rearward rotation of the vertical portion 22 is restricted. It has been. The inner diameter of the hole 23 of the holder 2 is slightly smaller than the outer diameter of the groove 12 of the tool head 1 so that friction can be generated between the tool head 1 and the holder 2.

In the storage section 3, the tool 10 is connected to the chuck section 11 of the tool head 1, the flange section 13 of the tool head 1 is held by the horizontal section 21 of the holder 2, and the hook section 25 of the holder 2. Is hooked on the rod 4 of the storage section 3.

In tooling, when attaching the tool head 1 to a machine tool (not shown), the holder 2 holding the desired tool head 1 is taken out of the storage unit 3 by hand, and the horizontal portion 21 of the holder 2 is removed. It is held in a substantially horizontal state, or the vertical portion 22 side of the horizontal portion 21 is inclined in the direction of gravity and transported to the machine tool. Then, the holder 2 is lifted and the shank portion 14 of the tool head 1 is pushed into the main shaft of the machine tool. After the tool head 1 is mounted on the main shaft, the holder 2 is separated from the tool head 1.

On the other hand, when the tool head 1 is stored in the storage part 3, the tool head 1 is held by the holder 2 so that the groove 12 of the tool head 1 is stored in the hole 23 of the holder 2. Then, the tool head 1 is removed from the machine tool. Then, the holder 2 holding the tool head 1 is held in the above-described posture and transported to the storage section 3, and the hook 25 of the holder 2 is hooked on the rod 4 of the storage section 3. At this time, since friction can be generated between the tool head 1 and the holder 2, even when the front end of the horizontal portion 21 is slightly inclined in the direction of gravity during tooling, the tool head can be used. 1 does not fall from the holder 2.

FIG. 3 shows a second embodiment of the present invention, in which claw portions 32 are provided on both sides of an upper portion of a vertical portion 22 ′ of a holder 2 ′ so as to be hooked on a locking hole 31 of a storage portion 3 ′. Is provided. A metal bar 33 is bent and welded to the periphery of the substantially semicircular hole 23 '.

In order to attach the holder 2 ′ to the storage section 3 ′ after holding the tool head 1, it is only necessary to hook the claw 32 into the locking hole 31 of the storage section 3 ′. It is easy to remove.

[0015]

[Effect of the invention]

 As described above, the tool head holder according to the present invention is arranged so that the horizontal portion having a substantially semicircular hole for receiving the groove on the outer peripheral surface of the tool head and the rear portion of the horizontal portion substantially perpendicularly intersect. It consists of a raised vertical part and a hook part provided on the upper part of the vertical part, so that the tool head groove can be received in the hole and the tool head can be transported between the storage part and the machine tool. The tool head can be housed in the storage section by hooking the stop on the rod of the storage section. Therefore, it is not necessary to turn the tool head at the time of tooling, so that the tooling time can be reduced and the operator can be prevented from being injured.
