In the utility model, the boring of stepped holes can be one-time completed, and the stepwise hole boring cutter has the advantages of high production efficiency and simple structure.
Description
Technical field
The utility model relates to the Machining Technology field, is specifically related to a kind of indexable staged hole boring cutter.
Background technology
At present, in machining, the boring endoporus generally with hilted broadsword processing, when needs boring shoulder hole, needs manual toolsetting to realize the processing dimension of workpiece in process, and this just needs to divide to process several times surplus is processed.This kind conventional method inefficiency, machining accuracy are not high, and the hand grinding cutter is lack of standardization, although be experienced skilled worker's operation, are difficult to guarantee the precision and the work efficiency of processing yet.
Summary of the invention
The utility model purpose is to provide a kind of indexable staged hole boring cutter, and the utility model has advantage of high production efficiency by the disposable boring processing of finishing shoulder hole.
The technical scheme that realizes the utility model purpose is as follows:
Indexable staged hole boring cutter, comprise cutter hub, at least be interval with three blade mount pads on the periphery of described cutter hub, be equipped with blade on each blade mount pad, wherein the second blade mount pad apart from the radial spacing at cutter hub center greater than the radial spacing of the first blade mount pad apart from the cutter hub center, the 3rd blade mount pad apart from the radial spacing at cutter hub center greater than the radial spacing of the second blade mount pad apart from the cutter hub center; The first blade mount pad, the second blade mount pad, the 3rd blade mount pad mount pad have axial spacing at interval successively.
The difference of the second blade mount pad apart from the radial spacing at cutter hub center and the first blade mount pad apart from the radial spacing at cutter hub center is 3mm, and the difference of the 3rd blade mount pad apart from the radial spacing at cutter hub center and the second blade mount pad apart from the radial spacing at cutter hub center is 3mm.
Be interval with four blade mount pads on the periphery of cutter hub.
It is 0.5mm that the first blade mount pad, the second blade mount pad, the 3rd blade mount pad have axial spacing at interval successively.
Adopted such scheme, at least be interval with three blade mount pads on the periphery of described cutter hub, these blade mount pads axially have spacing along cutter hub, and also there is pitch difference in the radial direction of cutter hub, therefore when work, blade on each blade mount pad participates in cutting successively, thereby is plastic shoulder hole by time processing, is beneficial to and enhances productivity.And the layout aspect of above-mentioned blade mount pad has is convenient to the cutting force that disperses each blade suffered, is beneficial to the service life that prolongs cutter.In addition, the utlity model has advantage of simple structure.
Blade on described each blade mount pad all has tool cutting edge angle, and the angle of this tool cutting edge angle is 80 °.The axial resistance that blade is subjected to when by tool cutting edge angle the dispersion feed being arranged is beneficial to the service life that prolongs blade.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the schematic diagram of the workpiece of employing milling cutter machine-shaping of the present utility model;
In the accompanying drawing, 1 is cutter hub, and 11 is the first blade mount pad, and 12 is the second blade mount pad, and 13 is the 3rd blade mount pad, and 14 is four blade sheet mount pad, and 2 is blade, and α is a tool cutting edge angle.3 is workpiece, 31 first holes, 32 first holes, 33 first holes, 34 first holes.
The specific embodiment
With reference to Fig. 1 and Fig. 2, indexable staged hole boring cutter of the present utility model, comprise cutter hub 1, be interval with the first blade mount pad 11, the second blade mount pad 12, the 3rd blade mount pad 13 and four blade sheet mount pad 14 on the periphery of cutter hub 1, be equipped with blade 2 on each blade mount pad, blade 2 is anchored on each blade mount pad by screw.Blade on each blade mount pad all has tool cutting edge angle α, and the angle of this tool cutting edge angle α is 80 °.Greater than the radial spacing of the first blade mount pad 11 apart from the cutter hub center, wherein, the blade mount pad is meant the distance of blade mount pad top apart from the cutter hub center apart from the radial spacing at cutter hub center to the second blade mount pad 12 apart from the radial spacing at cutter hub center.The difference of the second blade mount pad apart from the radial spacing at cutter hub center and the first blade mount pad apart from the radial spacing at cutter hub center is 3mm.Greater than the radial spacing of the second blade mount pad 12 apart from the cutter hub center, the difference of the 3rd blade mount pad apart from the radial spacing at cutter hub center and the second blade mount pad apart from the radial spacing at cutter hub center is 3mm to the 3rd blade mount pad 13 apart from the radial spacing at cutter hub center.Greater than the radial spacing of the 3rd blade mount pad apart from the cutter hub center, the difference of four blade sheet mount pad apart from the radial spacing at cutter hub center and the 3rd blade mount pad apart from the radial spacing at cutter hub center is 3mm to four blade sheet mount pad 14 apart from the radial spacing at cutter hub center.The first blade mount pad 11, the second blade mount pad 12, the 3rd blade mount pad 13 and four blade sheet mount pad 14 have axial spacing at interval successively.It is 0.5mm that the first blade mount pad, the second blade mount pad, the 3rd blade mount pad and four blade sheet mount pad have axial spacing at interval successively.The number of blade mount pad of the present utility model is provided with as required.
With reference to Fig. 2 and Fig. 3, when adopting cutter of the present utility model that workpiece 3 is carried out bore hole, at first workpiece is carried out boring by the blade on the first blade mount pad, bore first hole 31, blade workpiece on the first blade mount pad is, the blade on second, third and the four blade sheet mount pad is in idling conditions.When the blade completion of processing on the first blade mount pad dallied, the blade on the second blade mount pad then carried out boring processing to workpiece, bores second hole 32, in this process, the 3rd and four blade sheet mount pad on blade also be in idling conditions.When the blade completion of processing on the second blade mount pad dallied, the blade on the 3rd blade mount pad then carried out boring processing to workpiece, bores first hole 33, in this process, first and four blade sheet mount pad on blade also be in idling conditions.When the blade completion of processing on the 3rd blade mount pad dallied, the blade on the four blade sheet mount pad then carried out boring processing to workpiece, bores first hole 34, and in this process, the blade on the first and second blade mount pad also is in idling conditions.Finally process stepped hole as shown in Figure 3.
