Abstract
The utility model provides an inner spiral groove cutter head which is capable of processing deep spiral grooves, high in processing accuracy and easy to operate. The inner spiral groove cutter head comprises a box body, an input shaft and an output shaft, wherein the input shaft and the output shaft are rotatably arranged on the box body; the input shaft is used for driving the output shaft to rotate through a transmission mechanism; the input shaft and the output shaft can form an included angle less than 90 DEG C and used for mounting a cutter head of a milling cutter on the output shaft.
Description
Technical field
The utility model relates to the inner spiral groove milling head of processing inner spiral groove.
Background technology
Kind and the processing method of groove are more, but the processing of inner spiral groove is a processing technology that difficulty is large.The processing of internal thread spline, has electric pulse, broaching machine, the techniques such as cold extrusion.But these methods have larger limitation, processing technology complexity, machining accuracy is poor, and workpiece strength declines large.
Also have milling cutter on the power shaft to be arranged on rotation to process inner spiral groove, but now require the axis of workpiece to have a certain degree with power shaft (equating with the lead angle of inner spiral groove), power shaft moves along input shaft axis under the drive of actuating unit in rotating, workpiece phase opposing connection transfer input shaft is moving simultaneously, can on the inner hole wall of workpiece, process inner spiral groove.While movement along input shaft axis due to power shaft, actuating unit etc., can with the interfere in ends of workpiece, the degree of depth of the inner spiral groove in this way processing in input shaft axis direction is limited, cannot process the inner spiral groove that the degree of depth is larger.In addition, also there is the problems such as milling head rigidity of structure deficiency, directly affect spiral fluted machining accuracy, and this processing method is to requiring processing staff to have consummate operant level.
Utility model content
The purpose of this utility model is to provide a kind ofly can process deep spiral groove, machining accuracy is high, working (machining) efficiency is high, easy and simple to handle inner spiral groove milling head.
Inner spiral groove milling head of the present utility model, comprise casing, rotate the power shaft and the output shaft that are arranged on casing, power shaft drives output shaft rotation by transmission mechanism, and power shaft becomes to be less than the angle of 90 ° with output shaft, is arranged on output shaft for the cutterhead that milling cutter is installed.
The angle of described power shaft and output shaft can be 30 °, 45 °, 60 ° etc.
Above-mentioned inner spiral groove milling head, described transmission mechanism is gear drive.Described gear drive is one or more levels transmission mechanism.
Above-mentioned inner spiral groove milling head is provided with at least one strain part centered by input shaft axis on cabinet exterior, and strain part inner ring embeds on cabinet exterior, and strain part periphery is given prominence to cabinet exterior.Best, casing is a cylinder, and input shaft axis is coaxial with cylinder axis or parallel.Strain part external diameter and processed endoporus are in the same size, like this, are adding man-hour, and strain part is supported on processed inner hole wall, and the vibration meeting of casing is less, guarantee to add the stability in man-hour, can improve machining accuracy.
Above-mentioned inner spiral groove milling head, the front end of casing has processed groove, and groove has side and inclined-plane; Output shaft is connected with cutterhead through described inclined-plane; Cutterhead is parallel with inclined-plane.On casing, machined grooves is used for placing cutterhead, the integral rigidity of the inner spiral groove milling head that can break even, and long service life, machining accuracy is high.
Above-mentioned inner spiral groove milling head, is provided with cooling liquid outlet on the side of groove.The cooling fluid flowing out from cooling liquid outlet can be carried out cooling to working position.
Above-mentioned inner spiral groove milling head, casing is a cylinder, input shaft axis is coaxial with cylinder axis or parallel; Groove is positioned at cylindrical front end, and the axis of output shaft is perpendicular to groove floor.Like this, this inner spiral groove milling head overall structure is simple, intensity is high, easy to operate.
The beneficial effects of the utility model: the angle of power shaft and output shaft is exactly the lift angle that needs the inner spiral groove of processing, add man-hour, the axis of power shaft is coaxial or parallel with the endoporus of workpiece, the axis along power shaft in inner hole of workpiece such as casing moves, the power shaft being connected with power input mechanism drives output shaft rotation simultaneously, and cutterhead can process inner spiral groove on inner hole of workpiece wall.Because power shaft is parallel with inner hole of workpiece axis, thus when power shaft, casing move not can with the interfere in ends of workpiece, power shaft, casing etc. can move arbitrarily with respect to workpiece in input shaft axis direction, so can process the inner spiral groove of any degree of depth.Adopt the bevel gear transmission of drive bevel gear and driven wheel of differential engagement, the appearance and size that structure is small and exquisite, further reduced casing, the scope of application is wider, has also further strengthened the rigidity of this milling head simultaneously, can improve machining accuracy and working (machining) efficiency.
