There is a through hole at the center of described footstock, and the right of the upside of described footstock has a breach, and described breach is communicated with through hole.
Fine adjustment shaft between described fine setting door closure and trimming handle is provided with a hex nut.
The center of the end face that described connecting plate is connected with footstock has a centre bore, and during end face with centre bore is
The heart evenly has 3 grooves, and described groove is connected with centre bore.
Can relatively rotate between described cylinder and cylinder door closure.
The intermediate vertical of another end face of described connecting plate is provided with connecting axle, and described connecting axle has the Morse's taper matched with tailstock tool.
Described cylinder can replace to oil cylinder.
beneficial effect
The present invention relates to and a kind of adjustable centering clamp for numerical control machine is provided, utilize the principle of triangle polyester fibre, three bearings are used to be fixed by the afterbody of longaxones parts, longaxones parts is steadily processed, apparatus structure is simple, easy to operate, can be suitable for the axial workpiece with different-diameter, improve the crudy of product, reduce the percent defective of product.
