Description

A kind of ultrasound wave bench drill

Technical field

This utility model relates to producing equipment technical field, is specifically related to a kind of ultrasound wave bench drill。

Background technology

Bench drill is made up of base, column, turriform belt wheel, bead apex, drill bit feeding handle, main shaft frame, set lever etc., is widely used in the occasion of machine components processing, is the first-selection of manufacturing batch hole part。

More and more extensive in the use of current metal and hard brittle materia, especially ceramic material has the advantages such as hardness is high, wear-resistant, high temperature resistant, chemical stability is good, not oxidizable, if material has high hardness and fragility is so processed very difficult。Common drilling machine cannot complete the processing that hole in piece part requires at all。

Bench drill there will be lower column defects in the process carrying out hole machined: hole be polygon, boring position deflection or crooked, boring expands, hole wall is coarse etc.。

Hole is that polygon is caused by following situation: drill bit back angle is too big or two main cutting edge length, angle asymmetry cause。

The position deflection of boring or crooked caused by following situations: working surface tilts, auger axis and work top out of plumb, the amount of feeding are uneven, workpiece is fixed not tight。

Boring expands that to be because on drill bit ligament too big with built-up edge, the amount of feeding, drill bit swings, drill bit two main cutting edge has length and has height to cause。

Hole wall is coarse is because that relief angle is too big, drill bit is not sharp, cooling is not enough, and cutting fluid poor performance causes。

In the course of processing, drill bit also there will be problem, such as broken drill, the abrasion rapidly of drill bit cutting edge etc., the two phenomenon is mainly following situations and causes: the amount of feeding is too big, workpiece loosens, the blunt speed also continuing to use, cut of drill lip is too high, drill sharpening angle is unreasonable。In the part course of processing, the effect of cutting force makes part easily deform, particularly cutting fluid cutting region difficult to get access during deep hole processing, cause that cutting temperature is high, tool wear fast, produce built-up edge, thus causing cutting force to increase, working (machining) efficiency and precision is made to reduce, surface roughness increases, and life tools are short。

Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。

With reference to Fig. 1 and Fig. 2, a kind of ultrasound wave bench drill described in this utility model embodiment, support bar 20 afterbody is threaded and coordinates with base 2 screwed hole, fixed effect well and support bar 20 play the effect of slide rail。Drive lead screw 5 couples with base 2 bearing 1, rotation effective。Drive lead screw 5 is driven to move by shaking rotating disk 3, regulate the height of workbench 6 and drive the distance between cross bar 17 motor adjustment tool heads 15 and workbench 6 by cylinder 22, make the position reaching to meet processing part, workbench 6 has aperture and reuses through fluid pipeline 7 flow back fluid case 8 to meet part abrasive material abrasive particle liquid in the course of processing。

With reference to Fig. 1 and Fig. 4, take part to be processed and be put on workbench 6, with spanner, double nut 10 is unclamped, part is put between clamping device movable block and fixed block, by promoting movable block and turning the nut of up and down motion and make it clamp, reach the purpose of retaining element。Adjust swinging, telescopic bar 19, make position all around meet the requirement of processing part, lock the first stop hands handle。Fixed cover 21 and swinging, telescopic bar 19 adopt thread connection, and middle rest will be partially loaded on transducer 13 and horn 14, and with being screwed。Horn 14 lower part is then for checking whether it is the waveform required for processing part。

With reference to Fig. 3, Fig. 4 and Fig. 5, after supersonic generator 12 is correctly connected with oscillograph, again oscillograph is opened, again by hyperacoustic power supply opening behind school zero, start supersonic generator after a period of time, adjust ultrasonic frequency vibratory parameter, oscillograph will show a waveform, and hear that horn 14 has slight chatter, now need to observe the atomizating phenomenon of water, water the end of horn 14 with spoon water, see whether water flashes, if not, need also to adjust waveform, to the last occur till atomizating phenomenon。Finding that this waveform is the sharp wave peak with burr, this illustrates that waveform is correctly the waveform needing to obtain。Then pass through horn 14 and mechanical energy is vibrated displacement and the movement velocity amplification of particle, by transducer 13 transmission to tool heads 15。

With reference to Fig. 1, pouring fluid box 8 into after abrasive material adds suitable water stirring, adding water is purpose in order to play cooling when carrying out hole machined。Starting pump 9 to make abrasive material abrasive particle liquid arrive rifle head 11 through fluid pipeline 7 to go out to spray abrasive particle liquid, with regard to Impact abrasive abrasive particle when tool heads 15 moves up and down, abrasive material abrasive particle impacts machined surface again thus reaching the purpose of processing part。

The open a kind of ultrasound wave bench drill of this utility model in sum, penetration power is very strong, be hardly damaged object, spread speed is fast, simple in construction, stable movement, can realize the requirements such as multiple directions action, it is applicable to process various hard brittle materials, especially the non-conductive nonmetallic materials that miscellaneous equipment cannot be processed, the Low rigidity workpiece such as processing little, the thin-walled of force request is highly beneficial；Ultrasound wave processes steady noiseless, and process time is short, and the equipment of processing wants it simple, without complicated frame for movement, it is simple to regulates, has good promotional value。
