Abstract
The invention discloses a superhard tungsten carbide deep hole shock-resistant inner-cooling adjustable boring tool. The tool comprises a cemented carbide toolbar which is connected with a scale end of an eccentric bushing with scales through a screw, the other end of the eccentric bushing with the scales is connected with a non-standard side fixed toolbar, and the diameter of the eccentric bushing with the scales can be adjusted. According to the tool, the tool does not need to be directly adjusted through a tool setting gauge, and according to the required hole size precision and length-diameter ratio, the boring toolbar and the adjustable eccentric bushing with accurate scales are designed; according to the processed material, machine tool configuration, connection mode and rotation angle during the process, the cutting parameters of the tool in a static state are designed; and dimensional accuracy requirements can be ensured, and the tool is low in cost, is convenient and the manufacturing period is short.
Description
Technical field
The present invention relates to cold adjustable boring tool in a kind of superhard tungsten carbide deep hole shock resistance.
Background technology
High-precision hole is to add man-hour in diesel engine part, hydraulic part, the automobile and other industries, particularly cylinder head, requires interchangeability strong such as diesel engine cylinder cover installation installing hole, guide hole.The hole that high-end four-valve cylinder head is little and dark such as valve guide bushing bottom outlet and guide hole require dimensional accuracy below H7, below roughness Ra≤1.6um, and cylindricity, tapering≤6um, linearity≤5um.General domestic boring cutter processing is not reach drawing requirement, demands urgently improving.
Summary of the invention
For the problem that prior art exists, the object of the invention is to propose cold adjustable boring tool in a kind of superhard tungsten carbide deep hole shock resistance, by enforcement of the present invention, can guarantee dimension precision requirement, and cost is low, convenient, the manufacturing cycle short.
For reaching this purpose, the present invention by the following technical solutions:
Cold adjustable boring tool in a kind of superhard tungsten carbide deep hole shock resistance comprises:
The carbide alloy knife bar is connected with scale end with the eccentric bushing of scale by screw, is connected with the solid handle of a knife of nonstandard side with the other end of the eccentric bushing of scale, and this is with the eccentric bushing adjustable diameter of scale.
Preferably, described carbide alloy knife bar adopts superhard tungsten carbide boring cutter bar.
Preferably, described carbide alloy knife bar is provided with built-in water hole and directly cools off.
Preferably, the processing aperture is at 6～30mm, and draw ratio is at 5～20mm, below roughness Ra≤1.6um, and cylindricity, tapering≤6um, linearity≤5um.
Preferably, but described eccentric bushing left and right directions with scale is adjusted the point diameter size.
Compared with prior art, the present invention has following beneficial effect:
Among the present invention, without the direct toolsetting of tool setting gauge, on demand aperture size precision, the draw ratio of processing, design boring cutter bar and with the adjustable eccentric cover of exact scale; By machined material, lathe preparation, connecting mode and the anglec of rotation that adds man-hour, the cutting parameter when the design cutter is static; Can guarantee dimension precision requirement, and cost is low, convenient, the manufacturing cycle short.

The specific embodiment
The embodiment of the invention 1 provides cold adjustable boring tool in a kind of superhard tungsten carbide deep hole shock resistance, as shown in Figure 1 to Figure 3, comprise: carbide alloy knife bar 2, be connected with scale end with the eccentric bushing 3 of scale by screw 4, the other end with the eccentric bushing 3 of scale is connected with the solid handle of a knife 5 of nonstandard side, and this is with eccentric bushing 3 adjustable diameters of scale.Wherein, carbide alloy knife bar 2 can adopt superhard tungsten carbide boring cutter bar, uses the manufacturing of high tenacity formula materials, realizes high rigidity, high shock resistance, built-in water hole, directly cooling.Can improve linearity hole, surface quality and the dimensional accuracy of processed deep hole, relate to the aperture at 6～30mm, draw ratio is at 5～20mm.The dimensional accuracy, the surface quality that bore the hole are stable, below roughness Ra≤1.6um, and cylindricity, tapering≤6um, linearity≤5um.But adjust the point diameter size with the eccentric bushing left and right directions of scale, the diameter after when not needing tool setting gauge, adjustment can being known.The staight shank structure, working depth can must be asked Self-adjustment according to processing, can join the appointment blade of various label same sizes.
Among the present invention, can adjust length according to various different process requirements, adjustable eccentric cover with exact scale, but assisting user is adjusted to required scope easily, need not adjust at the cutter tool setting gauge, be adapted at most being used on the various numerically controlled machine tool, and the appointment blade of the various label same sizes of can arranging in pairs or groups, save the tool lapping time and significantly increase bore hole efficient.
The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
