The utility model can accurately adjust the radial dimension of the cutter block mounted on the cutter body through a screw thread micro-adjustment mechanism. The micro-adjustable milling cutter is applied to plain milling machines for completing the three-side groove processing that requires rather high precision by one pass.
Description
Technical field
The utility model relates to a kind of milling cutter, particularly relates to the fine-tuning milling cutter of higher cylinder of diesel engine of a kind of requirement on machining accuracy and bearing cap faying face.
Background technology
The faying face of cylinder of diesel engine and bearing cap has degree of precision to require (as Fig. 3), uses common apparatus (as vertical milling) and universal cutter (as slotting cutter) processing M
1Face and M
2Face needs feed more than 2 times, processing M
3, M
4Face needs twice tool setting, is difficult to guarantee L and L
1Required precision is wasted time and energy, and production efficiency is low.Address the above problem, use special plane (as special broaching machine) processing to guarantee.But the special machine apparatus expensive, utilization rate is low, particularly in the new product advanced development or small lot batch manufacture of diesel engine, is not suitable for using special purpose machine tool.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of fine-tuning milling cutter, goes up processing diesel engine cylinder block bearing cap faying face at common apparatus (vertical milling), has guaranteed requirement on machining accuracy, and milling cutter construction is simple, easy to use simultaneously, and cost is low.
The fine-tuning milling cutter of the utility model comprises cutter piece, cutter hub, micrometer adjusting screw, ejector pin, attachment screw, hold-down screw, micrometer adjusting screw is the band tapered configuration, the cutter piece fuses by attachment screw and ejector pin, be arranged in the cutter groove of cutter hub, micrometer adjusting screw is arranged in the locating hole at cutter hub center, and hold-down screw is fixed on the cutter piece on the cutter hub.
In the fine-tuning milling cutter of the utility model, cutter piece and attachment screw and ejector pin are provided with 6 respectively, and cutter hub is provided with 6 cutter grooves, and 6 cutter pieces are installed in respectively in 6 cutter grooves.The micrometer adjusting screw of band tapering contacts with the ejector pin afterbody, forms the screw thread micro-adjusting mechanism, can accurately adjust the radial dimension that is installed in 6 cutter pieces on the cutter hub by this screw thread micro-adjusting mechanism.
The utility model has the advantages that: the cutter radial size adjusting is convenient, and the production efficiency height is simple in structure, can reface, and cost is low.Be specially adapted on plain-milling machine, finish three higher groove processing of required precision.

Part is among the figure: 1-cutter piece (6), 2-cutter hub, 3-micrometer adjusting screw, 4-ejector pin (6), 5-attachment screw (6), 6-hold-down screw (12).
The specific embodiment
Fine-tuning milling cutter (as Fig. 1, Fig. 2) of the present utility model is the dedicated tool of the design for the higher cylinder of diesel engine bearing cap faying face (as Fig. 3) of requirement on machining accuracy.This fine-tuning milling cutter is applicable to that on plain-milling machine once feed finishes three higher grooves processing of required precision.
Fine-tuning milling cutter of the present utility model can not have under the situation of special plane, goes up processing cylinder of diesel engine bearing cap faying face as shown in Figure 3 at common apparatus (as vertical milling), has guaranteed requirement on machining accuracy.
As shown in Figure 1, cutter piece 1 (6) fuses by attachment screw 5 (6) and ejector pin 4 (6) respectively, install to respectively in equally distributed 6 the cutter grooves of cutter hub, micrometer adjusting screw 3 is screwed among the locating hole D1 at cutter hub center, up to the conical surface of micrometer adjusting screw with till 6 ejector pins all contact, then by hold-down screw 6 dead knife pieces on cutter hub.Assemble the blade of back on feeler block on the instrument mill and carry out sharpening assurance milling cutter radial dimension D.
During not passivation, can unclamp hold-down screw 6 when tool wear slightly, forward with Allen wrench rotary fine adjustment screw 3, make the conical surface on the micrometer adjusting screw promote 6 ejector pins 4, ejector pin 4 drives 6 cutter pieces 1 and moves certain distance in radial direction, till meeting the requirements, tightens hold-down screw 6 again.The conical surface of micrometer adjusting screw 3 is 30 °, and screw thread is M30 * 1.5, and pitch is 1.5, and micrometer adjusting screw revolves to turn around and moves axially 1.5mm, and the amount of movement of cutter piece on radius is:
1.5×tg(30°÷2)＝0.40mm。
If the adjustment amount of cutter piece on radius is 0.01, so, the number of degrees of micrometer adjusting screw rotation are:
360°×(0.01÷0.40)＝9°
Like this, graduation mark (as carving a graduation mark by per 9 °, every lattice represent 0.01) evenly is set on the cutter hub large end face, on the micrometer adjusting screw fillet surface, engraves a graduation mark again, just can adjust the radial dimension of milling cutter easily.
After the cutter passivation wearing and tearing, can outwards adjust 0.10 to cutter piece 1 on radius, promptly the rotary fine adjustment screw is 90 °, and sharpening guarantees the cutter radial dimension D on the instrument mill then.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to the above embodiments,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
