Claims

[Claims for Utility Model Registration] 1. A chuck part A consisting of a jaw body 1 that chucks a workpiece M and an operating rod 2 that operates the jaw body 1 is moved from the position of the main shaft S to a processing position to perform IJ. IJ Song is a chuck device for milling, etc., in which the operating rod 2 is mounted on a mounting member 3, and the mounting member 3 is connected to a shaft 6 having a drive unit 4 that opens and closes the claw body 1 using fluid pressure. The shaft 6 is slidably and rotatably supported, and the operating rod 2 is rotated by a transmission mechanism 5'' provided on the shaft, and during the rotation process of the operating rod 2, the chucked object is A chuck device for an automatic lathe, characterized in that it is equipped with a pushing positioning part B for a workpiece M. 2. The operating rod 2 serves as a lever for holding the chuck part A and a lever to assist in opening and closing the chuck claw body 1. The lever 2 is supported by the shaft 6 and moves the chuck claw body 1 in pressure contact with the tapered inner wall surface by sliding the chuck claw body 1 in the axial direction of the shaft 6. The chuck device described in 3. Practical use in which the mounting member 3 is a cylindrical body with a flange portion 3□, and is fitted into the fitting hole of the operating rod 2 through a gap d on the circumferential surface. Scope of patent registration request No. 1
The chuck device according to item 1 or 2. 4. The drive unit 4 consists of a piston 41 provided at one end of the shaft 6 and a cylinder 4° into which the piston 4 is slidably fitted, and is connected to a pressure air source and has a flow path 43 for supplying and discharging air.
4. A chuck device according to any one of claims 1 to 3, which is an air cylinder equipped with a utility model. 5. Utility model registration claims 1 to 4, wherein the transmission mechanism 5 is a pinion gear fixed to a shaft 6, and is operated by a cam C with a lever 5□ via a fan-shaped gear 5□ on the pinion gear. The chuck device according to any one of the following paragraphs. 6. The push-in positioning part B includes a flexible push-in body 7 provided in the moving path at the center of the chuck part A, and a bracket 73 with a mounting part 7□ of the push-in body 7 and a positioning piece 7°.
A chuck device according to any one of claims 1 to 5 of the utility model registration claim, which comprises: 7. The shaft 6 is rotatably and slidably supported on the main body, is operated in the axial direction by a cam 9 via a lever 8, and is connected to the mounting member 3 at one end on the shaft and the other end. A chaff device according to any one of claims 1 to 6, which is provided with a drive unit 4 and a drive unit 4.
