Description
Technical field
The present invention relates to the process tool of engineering goods part, especially multiaspect gang cutter milling mechanism.
Background technology
As you know, the most frequently used cutter in processing parts plane is exactly a face cutter, and generally milling several times of multilayer planar is arranged on the part to be processed.Like this, the multiple clamping part, time-consuming.If the multilayer planar on the part to be processed has higher depth of parallelism requirement, in parts fixation, design accurate in locating mechanism, otherwise the machining accuracy of part does not just reach requirement.
Summary of the invention
The purpose of this invention is to provide a kind of multiaspect gang cutter milling mechanism, can one-pass multilayer planar on just can milled part.
The technical solution adopted for the present invention to solve the technical problems is:
The large end face cutterhead is fixed on the milling machine spindle through the hole of left end; Mandrel from first axle journal of left number through key be contained in the large end face cutterhead from several the 3rd endoporus in a left side; Little retaining pad is contained in the left side of several the 3rd endoporus from a left side of large end face cutterhead; The hole that stay bolt passes on spring washer and the little retaining pad is contained in from first axle journal of left number, mandrel being fixed on the large end face cutterhead of mandrel; Swivel nut is contained in mandrel and can freely rotates from several second axle journal in a left side, and a plurality of radial blind holes are arranged on the cylindrical of swivel nut, mobile cutterhead through key be contained in mandrel from first axle journal of right number; Big retaining fills up the right side from right first axle journal of number that is fixed on mandrel with lag bolt and spring washer, moves the external screw thread of cutterhead left end and the screw-internal thread fit of swivel nut.
Six radial blind holes are arranged, the outer round surface annular knurl of swivel nut on the cylindrical of swivel nut.
Mandrel from first axle journal of left number through key be contained in the large end face cutterhead from several the 3rd endoporus in a left side, cooperate to be H7/h6.
Move cutterhead through key be contained in mandrel from first axle journal of right number, cooperate to be H7/g6.
The advantage of this multiaspect gang cutter milling mechanism is: stable cutting, machining accuracy be high, easy to operate, it is simple to make, cost is low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Accompanying drawing is the installation diagram of the multiaspect gang cutter milling mechanism of processing LM24-2C hulling machine gear-box.
1. large end face cutterheads among the figure, 2. swivel nut, 3. little retaining pad, 4. big retaining pad, 5. mandrel 6. moves cutterhead, 7. hulling machine gear-box front view, 8. hulling machine gear-box vertical view.
The specific embodiment
The side of LM24-2C hulling machine gear-box will process three planes, sees hulling machine gear-box front view (7) and hulling machine gear-box vertical view (8) in the accompanying drawing.Large end face cutterhead (1) is fixed on the milling machine spindle through the hole of left end, is used for processing the base plate side of hulling machine gear-box.Large end face cutterhead (1) is pressed the principle installed with milling cutter of layered cutting.The installation site of each milling cutter is according to being pressed by the allowance of milled part and milling cutter quantity: the milling cutter point of a knife is big to the distance of cutter hub rotation, and the milling cutter point of a knife is arranged in order to the little rule of the distance of cutter hub right side.So stable cutting.Mandrel (5) from first axle journal of left number through key be contained in large end face cutterhead (1) from several the 3rd endoporus in a left side, cooperate to be H7/h6.Little retaining pad (3) is contained in the left side of several the 3rd endoporus from a left side of large end face cutterhead (1), and the hole that stay bolt passes on spring washer and the little retaining pad (3) is contained in from first axle journal of left number, mandrel (5) being fixed on the large end face cutterhead (1) of mandrel (5).Swivel nut (2) is contained in mandrel (5) and from several second axle journal in a left side, can freely rotates, and both swivel nut (2) was H7/g6 with cooperating of mandrel (5).Large end face cutterhead (1) right side is pressed H9 manufacturing swivel nut (2) left side to the size of swivel nut (5) and is pressed the d9 manufacturing to the size of endoporus bottom surface.Six radial blind holes are arranged on the cylindrical of swivel nut (2), the outer round surface annular knurl of swivel nut (2), the swivel nut (2) of holding in hand of being convenient to the people rotates.Mobile cutterhead (6) is contained in through key and cooperating from first axle journal of right number of mandrel (5) is H7/g6.Big retaining pad (4) is fixed on the right-hand member from right first axle journal of number of mandrel (5) with lag bolt and spring washer, moves the external screw thread of cutterhead (6) left end and the screw-internal thread fit of swivel nut (2).With hand rotary threaded sleeve (2), mobile cutterhead (6) is moved right, withstand big retaining pad (4) after; Use the cylinder of suitable length again; Inject rotary threaded sleeve (2) in the blind hole on the cylindrical of swivel nut (2), mobile cutterhead (6) is moved right hold out against big retaining pad (4), loosening when preventing milling.Behind the big side on the intact hulling machine gear-box of milling, stop.Inject with the cylinder of suitable length in the blind hole on the cylindrical of swivel nut (2) and unclamp swivel nut (2),, mobile cutterhead (1) is moved to the left, hold out against the right side of the shaft shoulder of the maximum cylinder of mandrel (5) with hand rotary threaded sleeve (2).Drive, the little side of gear-box is accomplished in milling.The shift motion that moves cutterhead (6) is exactly that the right side of the shaft shoulder of the maximum cylinder of mandrel in the accompanying drawing (5) is to the distance b that moves cutterhead (6) left side.B is exactly the size of the little side of big side to the hulling machine gear-box on the hulling machine gear-box.Like this, one-pass just can have been cut the side omni mill of hulling machine gear-box one side.
