Linear tool magazine clamping jaw

Abstract

The invention discloses a linear tool magazine clamping jaw. The linear tool magazine clamping jaw comprises a body connected with a tool magazine installation frame, wherein the body is provided with a U-shaped opening used for containing a tool handle, and stop pins used for limiting the tool handle in the opening are arranged at the left end and the right end of the opening; an inner wall of the opening is symmetrically provided with a left flange and a right flange which are used for being matched with an annular groove in an outer wall of the tool handle to axially limit the tool handle; a clamping plate used for being matched with a positioning groove in the tool handle to limit the tool handle in a circumferential direction is arranged in the opening; an inner wall of the left / right flange is composed of a left / right inner arc surface and a left / right inner inclined surface, and the inner wall of the opening where the left / right flange is located is composed of a left / right outer arc surface and a left / right outer inclined surface; and the stop pins are movably connected with the body through a fixing frame. According to the invention, a tool handle can be accurately positioned in a tool magazine, the tool handle can be firmly locked and flexibly loosened, the action is safe and reliable, strength is high, a structure is simple, manufacturability is good, machining is convenient, the manufacturing cost is low, the service life is long, and the problems that when a spindle loosens a tool, the tool handle is ejected out, a tool magazine clamping jaw is bent and deformed, and the tool handle and a machine tool are damaged are effectively solved.

Description

technical field [0001] The invention belongs to the field of numerical control machining, and in particular relates to a claw of a linear tool magazine. Background technique [0002] In the field of CNC machining, linear tool magazines are widely used in CNC milling machines and CNC drilling machines because of their simple structure, low failure rate, and low cost. One-person multi-machine production operation mode. As the key component of the linear tool magazine, the jaws of the tool magazine have the functions of accurately positioning the knife handle in the tool magazine, locking the knife handle, and releasing the knife handle. [0003] The existing linear tool magazines mainly have structural forms such as plastic jaws, steel elastic jaws, and two-lobed jaws. There are common problems such as inaccurate positioning of the jaws, easy loosening, low strength, and many failures. Contents of the invention [0004] The object of the present invention is to overcome th...
