Description
Technical field
The utility model relates to a kind of boring bar tool, relates in particular to a kind of portable adjustable-depth brill, fraising plumb.
Background technology
Machining hole mainly adopts machine tooling and electric hand drill processing at present, use the machine tooling hole, cost is higher, and the position in hole is limited by the lathe shape, being permitted multipoint hole can't process, although and adopt electric hand drill processing cost low, present universal method is directly boring after the line, do not have other auxiliary mould, the dimensional tolerance in the degree of depth of machining hole, perpendicularity and hole is uncontrollable.Although more existing auxiliary workpiece for drilling tools can guarantee the perpendicularity in hole and certain precision, the working depth in uncontrollable hole.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of portable adjustable-depth brill, fraising plumb, can regulate the keyhole degree of depth, improve the drilling of electric hand drill precision, reduce the machining equipment occupancy, reduce cost, the resource such as conserve water, electricity, very practical.
The technical solution of the utility model is: a kind of portable adjustable-depth bores, the fraising plumb, the cylindrical shell that comprises both ends open, hollow, cylindrical shell lower end outer wall thread is connected with adjusting nut, be provided with spring in the cylindrical shell, spring is packaged in the cylindrical shell by back-up ring, back-up ring and the coaxial installation of cylindrical shell are coaxially installed with drill bushing on the back-up ring, be provided with some steel balls between drill bushing 4 and the back-up ring; The cylinder lateral wall outer surface is provided with the scale layer.
As preferably, adjusting nut is connected with cylindrical shell by the flush end holding screw, and cylindrical shell lower end outer wall has the chip removal otch.
As preferably, the drill bushing lower end is connected with back-up ring by holding screw, is provided with stop screw on the back-up ring.
As preferably, the back-up ring upper surface has the groove that cooperates with drill bushing, and steel ball is positioned at groove, and the steel ball surface is provided with grease layer.
As preferably, the pitch of adjusting nut is 1mm, and the axiality between cylindrical shell, drill bushing and the back-up ring is 0.012mm, and the perpendicularity of cylindrical shell, drill bushing and back-up ring is 0.02mm.
Therefore the beneficial effects of the utility model are: have very high perpendicularity and axiality requirement between cylindrical shell of the present utility model and drill bushing and the back-up ring, add the effectively perpendicularity of control hole and the dimensional accuracy in aperture of man-hour.The utility model is owing to have a depth adjustment, and the therefore effective working depth of control hole avoids using electric hand drill etc. to cause blind hole to become through hole because of misoperation or the degree of depth surpasses the product rejection that the regulation requirement causes.The utility model compact conformation, volume is small and exquisite, and is therefore easy to use, low processing cost, can manufacture in a large number, be particularly suitable for that the degree of depth, precision to the hole has higher requirements and can only with the operation process of electric hand drill processing, can be widely used in the industries such as machinery, building.The other flexible keyhole degree of depth of the utility model, stopping becomes through hole because misoperation causes blind hole, thereby makes the product failure with sealing function become the situation of waste product, very practical.

The specific embodiment
As a kind of embodiment of the present utility model, extremely shown in Figure 8 such as Fig. 1, a kind of portable adjustable-depth bores, the fraising plumb, the cylindrical shell 1 that comprises both ends open, hollow, cylindrical shell 1 lower end outer wall thread is connected with adjusting nut 2, be provided with spring 8 in the cylindrical shell 1, spring 8 is packaged in the cylindrical shell 1 by back-up ring 3, back-up ring 3 and cylindrical shell 1 coaxial installation are coaxially installed with drill bushing 4 on the back-up ring 3, be provided with some steel balls 5 between drill bushing 4 and the back-up ring 3, in the present embodiment, as preferably, drill bushing 4 lower ends are connected with back-up ring 3 by holding screw 6, are provided with stop screw on the back-up ring 3.Cylindrical shell 1 sidewall outer surface is provided with the scale layer.
In the present embodiment, as preferably, adjusting nut 2 is connected with cylindrical shell 1 by flush end holding screw 7, and cylindrical shell 1 lower end outer wall has the chip removal otch.Back-up ring 3 upper surfaces have the groove that cooperates with drill bushing 4, and steel ball 5 is positioned at groove, and steel ball 5 surfaces are provided with grease layer.The pitch of adjusting nut 2 is 1mm, and the axiality between cylindrical shell 1, drill bushing 4 and the back-up ring 3 is 0.012mm, and the perpendicularity of cylindrical shell 1, drill bushing 4 and back-up ring 3 is 0.02mm.
First adjusting nut 2 is screwed on the cylindrical shell 1 during assembling, in the cylindrical shell 1 of again spring 6 being packed into, keep free state; And then back-up ring 3 packed in the cylindrical shell 1, drill bushing 4 is packed in the back-up ring 3, keep first between the two the gap greater than the diameter of steel ball 5, then will be wiped with in steel ball 5 some grooves of packing between back-up ring 3 and the drill bushing 4 of lubricating grease, depress drill bushing 4 and make it and steel ball 5 Surface Contacts, regulate holding screw 6 and make that maintenance moves up and down consistent between drill bushing 4 and the back-up ring 3; Utilize flush end holding screw 7 that adjusting nut 2 is fixed on the cylindrical shell 1.
Use the key step of the utility model converted products as follows:
(1) turn adjusting nut 2 is aimed at zero graduation.
(2) the utility model is placed on the flat board, again the cutters such as boring fluted drill or reamer is put into plumb, clamp shank with electric hand drill, electric hand drill must hold out against back-up ring 3 of the present utility model.
(3) turn adjusting nut 2 is to the depth value of needs.
(4) one hand-held the utility model place cylindrical shell 1 bottom on the processed product surface that pulls the position, hole.
(5) start electric drill, slowly firmly press down, until stop screw withstands adjusting nut 2, till drill bit 9 can't continue deeply.Spring 8 is subjected to force compresses when pressing down, drill bit 9 slowly descends, owing to be provided with steel ball 5 between drill bushing 4 and the back-up ring 3, drill bushing 4 keeps certain interval with back-up ring 3 endoporus, drive simultaneously drill bushing 4 rotations when therefore drill bit 9 rotates, add the smear metal in man-hour and discharge from the chip removal otch of cylindrical shell 1 lower end, until get into desired depth, stop to apply downward active force, drill bit 9 withdraws from rapidly under the reaction of spring 8.Because the thread pitch of adjusting nut 2 is 1mm, its rotation half-turn is 0.5mm, so the pitch of screw thread has determined degree of regulation of the present utility model.
(6) take out electric drill, metal fillings in the hole is got rid of clean with Compressed Gas.
More than to a kind of portable adjustable-depth provided by the utility model bore, the fraising plumb carried out detailed introduction, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.To change of the present utility model with to improve will be possible, and can not exceed design and the scope that accessory claim can be stipulated.
