Description
Technical field
The utility model relates to the process tool of engineering goods part, especially step cutter.
Background technology
As you know, the most frequently used cutter in processing parts plane is exactly face cutter, and generally several times milling 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 accurately detent mechanism, otherwise the machining accuracy of part does not just reach requirement.
Summary of the invention
The purpose of this utility model provides a kind of step cutter, and the energy one-pass is with regard to the multilayer planar on the energy milled part.
The technical scheme that its technical problem that solves the utility model adopts is:
The large end face cutterhead is fixed on the milling machine spindle by the hole of left end, mandrel from first axle journal of left number by key be contained in the large end face cutterhead from left several the 3rd endoporus, little gear pad is contained in the left side from left several the 3rd endoporus of large end face cutterhead, the hole that stay bolt passes on spring washer and the little gear 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 left several second axle journal, a plurality of radial blind holes are arranged on the cylindrical of swivel nut, mobile cutterhead by key be contained in mandrel from first axle journal of right number, large gear pad is fixed on the right side from right first axle journal of number of mandrel with lag bolt and spring washer, movable knife the face left external screw thread held 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 by key be contained in the large end face cutterhead from left several the 3rd endoporus, cooperate to be H7/h6.
Mobile cutterhead by key be contained in mandrel from first axle journal of right number, cooperate to be H7/g6.
The advantage of this step cutter 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 drawings and Examples the utility model is further described.
Accompanying drawing is the installation diagram of the step cutter of processing LM24-2C hulling machine gear-box.
1. large end face cutterheads among the figure, 2. swivel nut, 3. little gear pad, 4. large gear pad, 5. mandrel 6. moves cutterhead, 7. hulling machine gear-box front view, 8. hulling machine gear-box top view.
The specific embodiment
The side of LM24-2C hulling machine gear-box will process three dimensions, sees hulling machine gear-box front view (7) and hulling machine gear-box top view (8) in the accompanying drawing.Large end face cutterhead (1) is fixed on the milling machine spindle by 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 of layered cutting milling cutter is installed.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 large 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 by key be contained in large end face cutterhead (1) from left several the 3rd endoporus, cooperate to be H7/h6.Little gear pad (3) is contained in the left side from left several the 3rd endoporus of large end face cutterhead (1), and the hole that stay bolt passes on spring washer and the little gear 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 can freely rotates from left several second axle journal, 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 hand of being convenient to the people is caught swivel nut (2) rotation.Mobile cutterhead (6) is contained in by key and cooperating from first axle journal of right number of mandrel (5) is H7/g6.Large gear fills up (4) and uses lag bolt and spring washer, is fixed on the right-hand member from right first axle journal of number, the external screw thread of mobile cutterhead (6) left end and the screw-internal thread fit of swivel nut (2) of mandrel (5).With hand rotary threaded sleeve (2), mobile cutterhead (6) is moved right, after withstanding large gear pad (4), use again the cylinder of suitable length, rotary threaded sleeve (2) in the blind hole on the cylindrical of reeve swivel nut (2), mobile cutterhead (6) is moved right hold out against large gear pad (4), loosening when preventing milling.Behind the large side on the complete 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), with hand rotary threaded sleeve (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).Drive, the little side of gear-box is finished in milling.The shift motion of mobile 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 of mobile cutterhead (6) left side.B is exactly the size of the little side of large 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.
