Abstract
The present invention relates to a compound socket scribing countersink drill which comprises drill bits and a drill rod, wherein a central drill is inserted in the inner cavity of the drill rod and the countersink drill; the drill bit of the central drill extends out of the drill bit of the countersink drill; a sleeve body is assembled out of the drill rod; the inner surface of a guiding screw thread sleeve and the outer surface of the sleeve body are correspondingly assembled on the sleeve body; a sliding and rolling limiting sleeve is assembled outside the screw thread sleeve; a rolling slide track and a thrust bearing are arranged between the sliding and rolling limiting sleeve and the screw sleeve; a regulating nut is assembled between a locking nut and the sliding and rolling limiting sleeve; a sealing cover is assembled on the sliding and rolling limiting sleeve; a regulating pad is assembled between the sealing cover and the thrust bearing. The countersink drill is positioned by shaft holes and is fastened by regulating screws. The drill rod is assembled in a main shaft hole of a drill press and makes a rotation motion for torque transmission. The countersink drill can steadily work, complete the size processing of a valve sealing nest in one step, and raise the precision and the smoothness of sealing nest processing.
Description
Technical field
The present invention relates to a kind of stroke of compound combined countersink drill of nest, belong to a kind of drilling machine machinery tools, be mainly used in the processing of valve seal nest size.
Background technology
The machining accuracy of the sealing of hydraulic valve and valve body end face seal nest has direct relation.When adopting prior art processing valve seal nest, process the valve body centre bore with drill bit earlier, be inserted in the centre bore with central shaft then and draw nest again behind the location.When drawing nest, because centre bore inner surface fineness is low, central shaft is easy to generate radially runout in centre bore, and it is not steady to work when causing combined countersink drill to draw nest, makes valve seal nest diameter dimension tolerance, the degree of depth and fineness to be difficult to reach the design standard requirement.At present, still not having a kind of specific purpose tool can be used in addresses the above problem
In the prior art, ZL94240932.9 utility model patent disclosed " two drill bit " is mainly used in cover class, the wide-aperture disposable processing of nut class part, to solve the hole drill shift phenomenon that bit change more causes.This pair drill bit comprises drill bit, drilling rod, drillstock, and centre drill interts in main force's brill inner chamber, and the centre drill external diameter and the main force bore internal diameter and coincide, and the drill bit of centre drill leans out the drill bit that the main force bores, and centre drill is removable fixedlying connected with drillstock.But above-mentioned " twin tip drill " is not suitable for processing valve seal nest.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of be used to process the valve seal nest draw the compound combined countersink drill of nest.
The objective of the invention is to realize by following technological means.
A kind of stroke of compound combined countersink drill of nest, comprise centre drill, combined countersink drill and drilling rod thereof, it is characterized in that said centre drill is inserted in drilling rod and the combined countersink drill inner chamber, combined countersink drill internal diameter and centre drill external diameter coincide and are contained on the centre drill, the drill bit of centre drill leans out the drill bit of combined countersink drill, adopts dismantled and assembled fixed connection structure between centre drill and combined countersink drill and the drilling rod, and body is equipped with in the drilling rod outside, guide thread cover inner surface coincide with the cover external surface and is contained on the body, and spacing sliding roll sleeve is contained in the thread bush outside.Said guide thread cover inner surface is contained on the body with tapered the coincideing of cover external surface.Be provided with rolling slideway and thrust bearing between spacing sliding roll sleeve and the thread bush, be connected between lock nut and the thread bush, be contained in body and above the spacing sliding roll sleeve.
Between above-mentioned lock nut and the spacing sliding roll sleeve adjusting nut is housed; Above the spacing sliding roll sleeve seal cover is housed, between seal cover and the thrust bearing adjusting pad is housed.
Above-mentioned rolling slideway can adopt steel ball rolling slideway; Steel ball and adjusting pad are housed, the full glycerine of remaining space filling in this slideway.
Above-mentioned lock nut and fixedly between the body, between adjusting nut and the seal cover and between drilling rod and the centre drill, adjustment screw is housed all.
The provided by the present invention stroke of compound combined countersink drill of nest, centre drill and combined countersink drill and drilling rod are with axis hole, keyway location, and adjustment screw is fixed.Be loaded on to rotate in the drill press spindle hole with Mohs awl bar and carry out the moment of torsion transmission, finish valve seal nest dimensioned.The centering of employing centre drill, the combined countersink drill stable working can satisfy sealing nest diameter dimension tolerance and fineness 1.6 requirements when drawing nest; Adopt the spacing sliding roll sleeve end face grade iron of seeking death, can satisfy sealing nest depth accuracy tolerance, obtain the 0.05-0.09 tolerance with interior precision.Adopt this combined countersink drill to draw nest and can time processing go out finished product, with existing first drill centers, locate the mode of drawing nest again with centre bore then and compare, improved sealing nest machining accuracy and fineness, and the location heart that can utilize centre drill to stay, directly process oil through.
Introduce the embodiment of the invention in detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the centre drill 1 of this combined countersink drill is inserted in drilling rod 9 and combined countersink drill 2 inner chambers, combined countersink drill 2 internal diameters and centre drill 1 external diameter coincide and are contained on the centre drill 1, the drill bit of centre drill 1 leans out the drill bit of combined countersink drill 2, adopts dismantled and assembled fixed connection structure between centre drill 1 and combined countersink drill 2 and the drilling rod 9.Above-mentioned drilling rod 9 is provided with adjustment screw hole 11, and drilling rod 9 outsides are with the body 7 that is tightly fixed, and the outer surface of body 7 is tapered; Guide thread overlaps 14 inner surfaces and body 7 outer surfaces coincide, and is assemblied on the body 7.Spacing sliding roll sleeve 3 is assemblied in thread bush 14 outsides; Be provided with steel ball rolling slideway 13 between spacing sliding roll sleeve 14 and the thread bush 3, steel ball and adjusting pad 12 are housed in the slideway 13, remaining space filling has glycerine.Above the slideway 13, between spacing sliding roll sleeve 3 and the thread bush 14, single face thrust bearing 4 and adjusting pad 12 are installed successively; Above the spacing sliding roll sleeve 3 seal cover 5 is housed.Be connected between lock nut 8 and the thread bush 14, be contained in body 7 and above the spacing sliding roll sleeve 3, between lock nut 8 and the spacing sliding roll sleeve 3 adjusting nut 6 be housed.
