Abstract

A special cutter disassembly bar applicable to a numerical control milling cutter relates to a tool for mechanical machining, and in particular to a special cutter disassembly tool applicable to a numerical control milling cutter. In order to solve the problem that a long pin is directly knocked by a hammer to disassemble a milling cutter, which lowers accuracy of a cutter handle and even causes damage to the cutter handle. The special cutter disassembly bar applicable to the numerical control milling cutter comprises a first bar and a second bar fixedly connected along an axial direction, the cross section of the second bar is smaller than that of the first bar, external threads are arranged on the outer wall of one end of the first bar connected with the second bar, and a hand sleeve or a handle is fixedly connected to the other end of the first bar. The special cutter assembly bar is particularly applicable to disassembling milling cutters in a numerical control milling machine.

Description

What be specially adapted for CNC milling cutter unloads the cutter rod

Technical field

The utility model relates to tool for mechanical machining, particularly relates to a kind of the Knife tool that unloads that is specially adapted for CNC milling cutter.

Background technology

Handle of a knife on the CNC milling machine is after using the vertebra shank milling cutter, the dismounting milling cutter is difficulty relatively, normally utilize the rod of having strong market potential to insert in the groove of vertebra shank milling cutter, use hammer that the vertebra shank milling cutter is pounded, directly knock the rod of having strong market potential with hammer, long-term use can make the precise decreasing of handle of a knife, sometimes even can damage handle of a knife.

Summary of the invention

The purpose of this utility model is directly to knock the rod of having strong market potential with hammer and unload milling cutter in order to solve, the problem that makes the handle of a knife precise decreasing even can damage, and then provide a kind of be specially adapted for CNC milling cutter unload the cutter rod.

The technical solution of the utility model is: the cutter rod that unloads that is specially adapted for CNC milling cutter of the present utility model comprises barred body one and barred body two, one end of barred body one and an end of barred body two are affixed vertically, the cross section of described barred body two is processed with external screw thread less than the cross section of barred body one on the outer wall of the end that barred body one and barred body two join.

The utlity model has following beneficial effect: the helicitic texture that the cutter rod matches with the vertebra shank milling cutter is unloaded in the utility model utilization; the vertebra shank milling cutter is released the handle of a knife of milling machine by the rotation of unloading the cutter rod; the protection handle of a knife is not subjected to directly knocking of external force, and then prolongs the service life of handle of a knife.

Description of drawings

Fig. 1 is the structural representation of handle of a knife and taper-shank cutter on the milling machine; Fig. 2 is a structural representation of the present utility model; Fig. 3 is the structural representation of the specific embodiment three.

The specific embodiment

The specific embodiment one: in conjunction with Fig. 1 and Fig. 2 illustrate present embodiment be specially adapted for CNC milling cutter unload the cutter rod, it comprises barred body one 1-1 and barred body two 1-2, the end of the end of barred body one 1-1 and barred body two 1-2 is affixed vertically, the cross section of described barred body two 1-2 is less than the cross section of barred body one 1-1, is processed with external screw thread 1-3 on the outer wall of the end that barred body one 1-1 and barred body two 1-2 join.External screw thread 1-3 on described barred body one 1-1 matches with the internal thread 2-1 of handle of a knife 2 one ends, the diameter of barred body two 1-2 is less than the internal diameter of taper-shank cutter 3 groove 3-1, and the length B of barred body two 1-2 is less than or equal to the distance A between outer face to the bottom surface of taper-shank cutter 3 groove 3-1 of handle of a knife 2 internal thread 2-1.

The specific embodiment two: in conjunction with Fig. 2 illustrate present embodiment be specially adapted for CNC milling cutter unload the cutter rod, it also comprises gloves 1-4, the described other end that gloves 1-4 is set in barred body one 1-1.When gloves 1-4 is flexible gum sleeve, more comfortable when the operator is held.Other compositions of present embodiment are identical with the specific embodiment one with annexation.

The specific embodiment three: in conjunction with Fig. 3 illustrate present embodiment be specially adapted for CNC milling cutter unload the cutter rod, it also comprises handle 1-5, handle 1-5 is that the cross section is square or circular steel pipe, handle 1-5 is vertically installed in the end of barred body one 1-1.Be "T"-shaped handle 1-5, can make the operator in rotation and advance when unloading the cutter rod more laborsaving.Other compositions of present embodiment are identical with the specific embodiment one or two with annexation.

The specific embodiment four: in conjunction with Fig. 2 and Fig. 3 illustrate present embodiment be specially adapted for CNC milling cutter unload the cutter rod, the end of described barred body 1-2 is a sphere, spherical radius is 12mm.Stressed more even during use, other compositions of present embodiment are identical with the specific embodiment one, two or three with annexation.

Operation principle of the present utility model is: be fixed with BT(JT50 on the milling machine) handle of a knife, the Morse taper shank milling cutter is arranged in the handle of a knife, to unload in the groove of barred body two by the screwed hole insertion taper-shank cutter of handle of a knife of cutter rod, because of the internal thread of the external screw thread on the barred body one with handle of a knife one end matches, by unloading the rotation of cutter rod, handle of a knife can at the uniform velocity be released with taper-shank cutter in the top of barred body two, thereby taper-shank cutter is laid down from milling machine.
