Abstract
The utility model relates to a spindle pull cutter device of a numerically controlled milling machine. The device comprises a spindle (8), pull claws, a pull rod (3) and pull claw pull nails. A through hole with the tapered front end is arranged in the spindle (8), the pull rod (3) capable of sliding is installed in the through hole, the pull claw pull nails are connected with the front end of the pull rod (3), and the plurality of pull claws are evenly installed in the space between the pull claw pull nails and the spindle (8) in the circumferential direction. The front ends of the pull claws can be fastened with the pull nails stretching into a cutter handle from the front end of the spindle (8). The device is simple in structure, capable of achieving replacement of cutter handles of JT standard and BT standard by simply replacing the pull claws and the pull claw pull nails, simple and convenient. The device reduces production cost due to the fact that the spindle is not required to be reprocessed, and other matched parts are not required.
Description
Technical field
The utility model relates to a kind of machine tool auxiliary device, particularly a kind of CNC milling machine main spindle broach device.
Background technology
At present, the structure of main shaft of numerical control machine tool broaching tool is that the handle of a knife rear portion is screwed into the handle of a knife blind rivet, and pulling claw tension handle of a knife blind rivet makes the handle of a knife conical surface be close to the main shaft conical surface under the effect of dish spring.Opening and straining of pulling claw is when it seesaws, to lean on variation and the broach travel of main shaft diameter of bore to change to realize.The most frequently used handle of a knife standard is JT standard (ISO 7388/1-A type is equal to German DIN 69871/1 type, is equal to Chinese GB10944) and BT standard (Japanese MAS 403BT) at present.Because the handle of a knife size of same size various criterion is different; Handle of a knife blind rivet size is also different; This just causes the pulling claw impulse stroke of various criterion different, and it is different to be deep into the inner position of main shaft, and hole dimension is also different in the main shaft of therefore suitable two kinds of handle of a knife broaching tool devices.For satisfying demands of different, lathe manufacturer also will process, assemble other kits such as different pull bars, loose knife oil cylinder and even main shaft except that the pulling claw that will process, assemble two kinds of various criterions, pulling claw blind rivet at present.After if complete machine is accomplished assembling, change again processing parts if desired, ressemble main shaft portion, waste time and energy.
Summary of the invention
The utility model technical problem to be solved provides a kind of CNC milling machine main spindle broach device, and is simple in structure, can be implemented in again machining spindle and drop into the handle of a knife of easy replacing BT standard and JT standard under the situation of other kits.
The utility model solves the technical scheme that its technical problem adopted: a kind of CNC milling machine main spindle broach device is provided; Comprise main shaft, pulling claw, pull bar and pulling claw blind rivet; The inside of described main shaft has the through hole that a front end has tapering; The inside of described through hole is equipped with slidably pull bar, and the front end of described pull bar is connected with the pulling claw blind rivet, and described pulling claw blind rivet along the circumferential direction evenly is equipped with several pulling claws in the space of main shaft; The rear end of described pulling claw and pulling claw blind rivet interlock, and the front end of described pulling claw interlocks with the handle of a knife blind rivet that stretches into from front-end of spindle.
Described pulling claw is special-purpose pulling claw of JT standard handle of a knife or the special-purpose pulling claw of BT standard handle of a knife.
Described pulling claw blind rivet is special-purpose pulling claw blind rivet of JT standard handle of a knife or the special-purpose pulling claw blind rivet of BT standard handle of a knife.
Beneficial effect
The utility model relates to a kind of CNC milling machine main spindle broach device; Simple in structure, only need replacing pulling claw and pulling claw blind rivet just can realize changing the outfit of JT standard handle of a knife and BT standard handle of a knife, simple and convenient; Do not need again machining spindle and drop into other kits, reduced production cost.
Description of drawings
Tension and relaxation state structure chart when Fig. 1 is the installation of the described JT standard of the utility model handle of a knife;
Tension and relaxation state structure chart when Fig. 2 is the installation of the described BT standard of the utility model handle of a knife.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Shown in Fig. 1-2; The embodiment of the utility model relates to a kind of CNC milling machine main spindle broach device; Comprise main shaft 8, pulling claw, pull bar 3 and pulling claw blind rivet, the inside of described main shaft 8 has the through hole that a front end has tapering, and the inside of described through hole is equipped with slidably pull bar 3; The front end of described pull bar 3 is connected with the pulling claw blind rivet; Described pulling claw blind rivet along the circumferential direction evenly is equipped with 4 pulling claws in the space of main shaft 8, the rear end of described pulling claw and pulling claw blind rivet interlock, and the front end of described pulling claw can interlock with the handle of a knife blind rivet that stretches into from main shaft 8 front ends; Described pulling claw can be special-purpose pulling claw 1 of JT standard handle of a knife or the special-purpose pulling claw 5 of BT standard handle of a knife, and described pulling claw blind rivet can be special-purpose pulling claw blind rivet 2 of JT standard handle of a knife or the special-purpose pulling claw blind rivet 6 of BT standard handle of a knife.
