Summary of the invention
The purpose of this invention is to provide that a kind of overall structure is simple, rotation and feed motion by a driving mechanism finish, equipment cost is low, the cutter driving device that is used for metal cutting equipment of processing ease, overcomes the deficiencies in the prior art.
Cutter driving device for metal cutting equipment of the present invention, but comprise casing and the main shaft that is supported on the front portion mounting cutter on the casing, the rear portion of main shaft and the line shaft in the rotary drive mechanism join, it is characterized in that: be connected to connector between described main shaft and the line shaft, key syndeton for moving to axial between connector and the line shaft, the connector outside is provided with roller, roller and cam path match, cam path is located on the madial wall of cam front portion, the cam rear sleeve is contained in the line shaft outside and connects rotary drive mechanism, and the outside of connector and the inboard of cam match and can move to axial.
Cutter driving device for metal cutting equipment of the present invention, wherein said main shaft is bearing in collar bush endoporus place by bearing, axially is slidingly matched outside the collar bush with the flange cover, and the flange cover is fixedlyed connected with casing.
Cutter driving device for metal cutting equipment of the present invention, wherein said rotary drive mechanism is the gear drive that joins with motor, comprise the left box body that joins with casing, at left box body and casing upper support power transmission shaft is arranged, the rear portion of cam is bearing on the casing by bearing, second gear and the 3rd gear are housed on the power transmission shaft, the 5th gear that is meshed with second gear is housed in the termination of line shaft, the 4th gear that is meshed with the 3rd gear is equipped with at the rear portion of cam, first gear that is meshed with motor gear on the motor is equipped with in the termination of power transmission shaft, and motor is fixedly connected on the left box body by the end plate of left box body side.
The present invention compared with prior art, the main shaft that driving mechanism not only can drive mounting cutter rotates, and also can make the main shaft axially-movable simultaneously, reaching cutter can rotate, and can do feed motion again, and entire equipment is simplified, also reduced simultaneously the cost of equipment, processing ease.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
As shown in Figure 1: 8 is casing, is connected with left box body 5 in the left end bolting of casing 8, and the side bolting of left box body 5 has end plate 2, and motor 1 is connected with end plate 2 bolting, and the output shaft on the motor 1 is equipped with motor gear 29.On casing 8 and left box body 5, be supported with power transmission shaft 4 by bearing, first gear 3 that is meshed with motor gear 29 is installed in the termination of power transmission shaft 4.At power transmission shaft 4 second gear 6 and the 3rd gear 7 are installed.
Fixedlying connected with an end of connector 20 by main shaft pin 19 in the termination of main shaft 18, is in axial sliding connection for spline between the other end of connector 20 and the line shaft 25.The outside at connector 20 is connected with roller 12 by jackscrew 11, and roller 12 matches with cam path 22, namely places in the cam path 22.Cam path 22 is located on the anterior madial wall of cam 21.The rear sleeve of cam 21 is contained in line shaft 25 outsides, and is bearing on the casing 8 by bearing, and at the baffle ring 23 that the inboard useful baffle ring pin 24 of cam 21 connects, cam 21 is rotatable with respect to line shaft 25.The 5th gear 28 is housed in the termination of line shaft 25 is meshed with second gear 6, the 4th gear 26 is housed at cam 21 rear portions is meshed with the 3rd gear 27.Be connected with the axial limiting that nut 27 is used for the 4th gear 26 at cam 21 posterior end head threads. Second gear 6 and 28 engagements of the 5th gear can drive line shaft 25 and rotate, the engagement of the 3rd gear 7 and the 4th gear 26 can drive cam 21 and rotate, it is differential to reach between line shaft 25 and the cam 21 realization when rotating, and namely line shaft 25 and cam 21 are relative to rotating.
Processing for convenience, cam path 22 can be divided into left and right two parts with cam 21, and left half and right half are combined into one by the adapter sleeve 9 of outside suit, and fixing by left attachment screw 10 and right attachment screw 13.
