Abstract
The utility model discloses a counterbore machining drill. The drill comprises a drilling handle which is conveniently clamped by a drill clamping head and extends axially along the vertical direction, wherein a thin-diameter twist drill section for drilling the small-diameter section of a counterbore is arranged at the lower part of the drilling handle; a thick-diameter twist drill section with the radial size larger than that of the thin-diameter twist drill section is arranged on the drilling handle and above the thin-diameter twist drill section; and a 90-degree stepped twist drill section for drilling the conical countersunk head part of the conterbore is arranged at the connecting transitional position between the thick-diameter twist drill section and the thin-diameter twist drill section, and is of a structure with a large upper part and a small lower part. When the counterbore machining drill is used for driving the drilling handle to do rotary movement, the thin-diameter twist drill section finishes the drilling on the small-diameter section of the counterbore, while the 90-degree stepped twist drill section on the drilling handle finishes the drilling on the conical countersunk head part of the conterbore, therefore, the counterbore on a plate for buildings can be drilled and molded once through the machining drill provided by the utility model.
Description
Technical field
The utility model belongs to the boring processing technique field, particularly a kind of being used for the hole counter sink processing drilling tool of processing of structural lumber.
Background technology
Building field and civil buildings prefabricated house board such as the calcium silicate boards of being convenient to processing and manufacturing, convenient installation again of adopting are constructed more at present; Calcium silicate board mainly is the both sides matrix with the calcium silicate board; Inject the heat insulating polyurethane foam liquid in the centre; Process through special processes such as high-pressure foam, curing, cuttings again, realize the bonding compound of core and calcium silicate board plane materiel.
When construction, sheet material needs overlap joint each other, and this is just need on the calcium silicate board of the both sides up and down of sheet material, bore row's counter sink, overlaps so that carry out sheet material during construction.Present bore process is to bore an aperture with hand drill earlier, bores counter sink again, manually with after the sheet material upset, repeats above-mentioned drilling operation more then, and borehole accuracy is not high like this, and efficient is low and working strength of workers is higher.
The utility model content
The purpose of the utility model is to provide a kind of can process the path section of counterbore and the counter sink processing drilling tool of taper countersunk head portion, the lower technical problem of working (machining) efficiency when on structural lumber, processing counter sink to solve in the prior art.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: counter sink processing drilling tool; Described drilling tool comprises the drillstock that axially extends along the vertical direction of being convenient to the drill chuck clamping when using; Be provided with in the bottom of drillstock and be used for the hole thin footpath fluted drill section of processing of the path section of counter sink; Above the fluted drill section of thin footpath, be provided with the particle size fluted drill section of radial dimension on the drillstock greater than the radial dimension of thin footpath fluted drill section; The transition position that is connected that bores between the section particle size fluted drill section and thin footpath fiber crops is provided with hole 90 degree step drill sections of processing of the taper countersunk head portion that is used for counter sink, the big up and small down structure of this 90 degree step drill section.
Between described 90 degree step drill sections and the thin footpath fluted drill section is the level and smooth cambered surface transition of indent.
The beneficial effect of the utility model is: the drillstock of counter sink that the utility model provided processing drilling tool is provided with and is used for the hole thin footpath fluted drill section of processing of the path section of counter sink; On drillstock, also be provided with the 90 degree step drill sections that taper countersunk head portion holes and reaming is processed that are used for counter sink; So in use; When drill chuck drive drillstock is done gyration; Thin footpath fluted drill section is accomplished the boring processing to the path section of counter sink, and the degree of 90 on drillstock step drill section is accomplished the boring processing to the taper countersunk head portion of counter sink, and the counter sink on the structural lumber can be by the processing drilling tool that the utility model the provides machine-shaping of once holing like this; Effectively raise the working (machining) efficiency of the counter sink on the structural lumber, reduce labour intensity.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the counter sink processing drilling tool that provides of the utility model.
The specific embodiment
As shown in Figure 1; A kind of embodiment of counter sink processing drilling tool; Counter sink processing drilling tool among this embodiment comprises the drillstock 1 that axially extends along the vertical direction of being convenient to the drill chuck clamping when using; The top of drillstock 1 has the clamping part that supplies drill chuck to be fixedly clamped when using; Be provided with in the bottom of drillstock 1 and be used for the hole thin footpath fluted drill section 5 of processing of the path section of counter sink, this thin footpath fluted drill section 5 is the main body of drilling tool, and cutting edge and row through fluted drill section end, thin footpath cut groove; Accomplish boring; Above thin footpath fluted drill section 5, be provided with the particle size fluted drill section 2 of radial dimension greater than the radial dimension of thin footpath fluted drill section on the drillstock 1, boring between the section 5 the transition position that is connected particle size fluted drill section 2 and thin footpath fiber crops is to be used for hole 90 degree step drill sections 3 of processing of taper countersunk head portion to counter sink, this 90 degree step drill section 3 be level and smooth cambered surface 4 transition between the fluted drill section 5 directly carefully.
During use; With corresponding being installed in the drill chuck of the clamping part on the main drillstock of drilling tool; Do gyration by drill chuck through main drillstock drive fluted drill and alloy blade; Thin footpath fluted drill section 5 is accomplished the boring processing to the path section of counter sink, and the boring processing that the degree of 90 on drillstock step drill section 3 is accomplished the taper countersunk head portion of counter sink, thereby realize time processing moulding to the counter sink on the calcium silicate board for building.Because the material of calcium silicates for building own; Add man-hour when adopting above-mentioned drilling tool that sheet material is holed; Resulting scrap is Powdered, and this Powdered scrap is not high to the chip removal functional requirement of drilling tool, so need not propose very high chip removal requirement to drilling tool to chip removal.
Drillstock in the foregoing description promptly can be applicable on the drill chuck of electric hand drill, also can be fixedly mounted on the special-purpose drilling machine, installs and uses all more convenient.
