Problems solved by technology

In addition, since the shaft of the mandrel needs to be replaced when the tapered surface of the shaft is damaged, there is a problem that a large amount of work is required.
[0010] In addition, although it is possible to use the surface contact between the tapered surface provided on the outer periphery of the shaft and the tapered inner surface of each clamp, and the abutting surface of the shaft and The surface contact between the butt surfaces of each jig combines these two parts to achieve super-strong cutting, but there is no such invention

Embodiment 1

[0147] Embodiment 1 of the spindle of the present invention is shown in Figure 1 ~ Figure 4 and explain it. The spindle 91 used for the spindle 7a is provided with a flange portion on the front end surface of the spindle case 93, and has a substantially cylindrical shape except for the flange portion.

[0148] In addition, the shaft 90 is rotatably mounted on the bearing 93a provided on the front side and the bearing 93b provided on the rear side, and the front cover 93c is installed on the front side of the spindle box 93, and the rear cover is installed on the rear side, so that the shaft 90 penetrates the front cover 93c. And the rear outer cover protrudes outward.

[0149] An outer sleeve 16 having a tapered outer surface 16a is attached to the outer periphery of the front head end of the shaft 90, and an outer spring 17a is attached to the rear side of the outer sleeve 16, and the outer sleeve 16 is pushed forward by the outer spring 17a. The surface of the shaft locat...

Embodiment 2

[0171] Embodiment 2 of the tool holder is shown in Figure 6 ~ Figure 8 and explain it. Figure 6 ~ Figure 8 All are diagrams showing a state in which the tool holders 2 a to 2 c are gripped by the mandrel 91 . All of the tool holders 2a to 2c have outer pull studs 11 as outer grasping portions. The tool jigs 2a to 2c do not require the inner grasping portion, but by making the outer pull stud 11 having the hole 11e through which the inner pull stud can pass, it can be used in each of the other jigs to achieve common use of parts.

[0172] The outer pull stud 11 has an outer head portion 11a and an outer neck portion 11b, and a chamfered portion 11c is provided at the rear end. In the fixture base 12,20,26.

[0173] If the outer ball 92a is located in the outer large-diameter portion 90e, the outer clamping mechanism is set to a loosened state and the outer pull stud 11 is inserted, the outer head portion 11a of the outer pull stud 11 will push the outer ball 92a to the fro...

Abstract

Provided is a double grasping mechanism comprising a double grasped part and a double gripping mechanism, and also provided are a spindle, a holder holding mechanism, a main shaft, and a holder holding device each having the double gripping mechanism, and a tool holder, a chuck holder, and a clamp holder. The double grasped part comprises an external pull stud (11) and internal pull studs (22, 32, 42, 55). The double gripping mechanism comprises: an external gripping mechanism including an external major diameter portion (90e), an external minor diameter portion (90g), an external draw bar (85), and an external ball (92a); and an internal gripping mechanism including an internal major diameter portion (85b), an internal minor diameter portion (85c), an internal draw bar (84), and an internal ball (92b). The tool holders (2a to 2c) have the external pull stud (11). The chuck holders (6a to 6d) have the external pull stud (11) and the internal pull studs (22, 32). The clamp holders (8a, 8b) have the external pull stud (11) and the internal pull studs (42, 55).

Description

technical field [0001] The present invention relates to a gripping mechanism configured to allow any one of a tool, a chuck, and a clamp mechanism (hereinafter simply referred to as "chuck, etc.") to be attached to an arbor used in a spindle of a machine tool, and relates to the following content That is, by being able to attach and detach a plurality of types of chucks to the same spindle, it is possible to perform multiple types of processing or multi-step processing with a single machine tool. Background technique [0002] Conventionally, there has been an invention related to a spindle for a tool (for example, refer to Patent Document 1). However, even though these inventions can hold the pull studs of the tool holders, they cannot accommodate the chuck or clamp mechanism. [0003] In addition, there has been an invention related to a spindle for a chuck (for example, refer to Patent Document 2). However, these inventions do not maintain the pull stud or clamp mech...
