Abstract
The utility model discloses a high-strength boring and milling shaft mechanism which comprises a boring rod main shaft. The boring rod main shaft is connected with an inner sleeve of the main shaft through a key, and the inner sleeve of the main shaft is arranged inside an outer sleeve of the main shaft in an assembling mode. A facing cutter is arranged on the outer sleeve of the main shaft in a clamping mode, and the end face of the facing cutter is perpendicular to the center line of a boring rod. A motor shaft of a servo motor is connected with a gear speed changing mechanism to drive a main shaft gear to rotate. The main shaft gear is connected with the inner sleeve of the main shaft through a guide key. One end of the boring rod main shaft is assembled with a protective knife handle through a broaching tool mechanism, the protective knife handle is provided with the facing cutter in an assembling mode, and the diameter of the protective handle is greater than the diameter of the boring rod. The perpendicularity of the end face of the facing cutter which is clamped by the inner sleeve of the main shaft and the center line of the boring rod main shaft is guaranteed to be within 0.005 mm. According to the high-strength boring and milling shaft mechanism, the shortcoming of lack of rigidity due to the fact the a boring rod shaft is arranged on a facing milling large cutter disk through the broaching tool mechanism is overcome, and meanwhile, after facing milling is finished, a facing milling disk cutter does not need to be dismantled, only is the protective knife cutter dismantled, the boring rod shaft extends out, and boring can be achieved only by the fact that a boring cutter is mounted.
Description
Technical field:
The utility model relates to the boring and milling mainshaft mechanism, uses when being specially adapted to horizontal boring-mill work.
Background technology:
Existing horizontal boring and milling main shaft boring bar diameter is generally Φ 110～Φ 130, the sky that hits, thereby have all not enough weakness of flexural rigidity and moment of torsion rigidity, by tool-broaching mechanism large cutterhead heavy cut facing cut is installed, there are the shortcomings such as vibration, bite is little, the cutting feeding is slow, and facing cut efficient is low.
Summary of the invention:
Task of the present utility model is to dismantle a kind of high strength boring and milling mainshaft mechanism of facing cutter behind a kind of boring and milling main shaft heavy cut of proposition, large cutterhead, the facing cut.Task of the present utility model is finished like this, a kind of high strength boring and milling mainshaft mechanism, it comprises spindle of boring bar, it is characterized in that: spindle of boring bar is connected by key with the main shaft inner sleeve, be equipped with the main shaft inner sleeve in the spindle jacket, handle is closing facing cutter on the described spindle jacket, end face is vertical with the spindle of boring bar center line, motor shaft on the servomotor is connected the drive shaft gear and rotates with gear shift, described mainshaft gear is connected by feather key with the main shaft inner sleeve, spindle of boring bar one end is equipped with facing cutter by tool-broaching mechanism and protection handle of a knife assembling on the protection handle of a knife, applies mechanically screw in facing cutter and the main shaft and is connected.The diameter of described protection handle of a knife is greater than the spindle of boring bar diameter.Described main shaft inner sleeve handle closes the facing cutter end face and spindle of boring bar center line perpendicularity should guarantee in 0.005mm.
The utlity model has following effect: the utility model has been avoided the shortcoming of the large cutterhead of facing cut by tool-broaching mechanism installation boring bar axle rigidity deficiency, after facing cut finishes simultaneously, needn't dismantle the facing cut dise knife, only need unload the protection handle of a knife, the boring bar shaft extension goes out, and boring cutter is installed can be carried out Boring, the utility model has also been given full play to the permanent torque characteristics of spindle servo electric machine, adopt the new material cutter, realize dark bite, cut fast the high efficiency facing cut processing of feeding.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Drawing explanation: 1, servomotor, 2, gear shift, 3, main spindle box body, 4, spindle jacket, 5, mainshaft gear, 6, key, 7, the main shaft inner sleeve, 8, spindle of boring bar, 9, feather key, 10, tool-broaching mechanism, 11, the protection handle of a knife, 12, facing cutter, 13, coolant jacket.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, spindle of boring bar 8 is connected by key 6 with main shaft inner sleeve 7, the main shaft inner sleeve is contained in 4 li rotations of spindle jacket by bearing, spindle jacket is installed on the main spindle box body 3, put in the main shaft closing facing cutter 12, end face is vertical with the spindle of boring bar center line, and perpendicularity guarantees in 0.005mm, spindle of boring bar leads with feather key 9, can be in arrow W axially-movable shown in Figure 1; Motor shaft on the servomotor 1 is connected drive shaft gear 5 and rotates with gear shift 2, the main shaft inner sleeve is connected by feather key with mainshaft gear, output torque can reach 1308mm, applying mechanically high-strength screw in facing cutter and the main shaft is connected, the pin location, spindle of boring bar is equipped with protection handle of a knife 11 by tool-broaching mechanism 10, the protective knife shank diameter is greater than the spindle of boring bar diameter, be equipped with facing cutter on the protection handle of a knife, the purpose of assembling protection handle of a knife is for fear of adding man-hour, enter iron pin impurity from the taper shank of spindle of boring bar, coolant jacket 13 is sleeved on the spindle jacket, and spindle jacket is anchored on the main spindle box body.Facing cut takes off the protection handle of a knife after finishing, and spindle of boring bar stretches out, load onto folder boring cutter cutter, just can directly carry out Boring, thereby guarantee the vertical precision of hole and end face, can carry out the outer circulation cooling to main shaft bearing by coolant jacket, main shaft high-speed cutting processing is achieved.
