Abstract

The utility model relates to a multi-head adjustable round drilling machine which is composed of a machine body, a cross beam, a housing, etc. A spline transmission shaft is arranged in the cross beam. The distance among multi-head machining drilling seats can be adjusted at will by a distance adjusting spline transmission shaft and a distance adjusting transmission screw rod, and the distance can be kept unchanged in order to achieve the purpose of simultaneously machining through holes by multiple heads. The utility model greatly improves productivity, reduces manufacture cost, and obviously improves machining precision.

Description

Multiple-head adjustable row-hole drilling machine

Technical field: the utility model relates to a kind of machining equipment, particularly relates to a kind ofly can process porous simultaneously, and the adjustable multiple-head adjustable row-hole drilling machine of pitch-row.

Technical background: in daily life, all need on the crossbeam of a lot of burglary-resisting windows to be processed into several equidistant through holes, be used for the insertion of anti-thefting strip.Crossbeam on processing burglary-resisting window on the general drilling machine, all need on crossbeam, rule, equal length of equal portions crossbeam, to calculate on the crossbeam needing to process what through holes, mark signature line then, towards locating hole, crossbeam is placed on the drilling machine processing in a hole, a hole, Jia Gong through hole like this, efficient is lower on the one hand, wastes a large amount of time; On the other hand, required precision can not get the assurance of essence.The purpose of this utility model will provide a kind of multiple-head adjustable row-hole drilling machine exactly, and it can disposablely finish the processing of porous, and the pitch-row between the Kong Yukong can need be regulated at all arbitrarily, and the precision of control can reach millimetre-sized level.

Summary of the invention: the utility model multiple-head adjustable row-hole drilling machine is made up of lathe bed, crossbeam, case, drill bit, retaining mechanism, it is characterized in that: be respectively arranged with spline shaft in the crossbeam, roll adjustment spline shaft, roll adjustment turn-screw; Described spline shaft is provided with several bevel gears and links to each other with drill bit respectively, is provided with the tooth bar converter at the middle part of location drill bit, is connected with second drill bit by tooth bar, is provided with scale on the top of spitting drill; Described roll adjustment spline shaft is provided with several spline silk braids, and each spline silk braid is fixed on the boring anchor with junction of the edges of two sheets of paper sieve silk, and an end of described boring anchor is fixed on the roll adjustment spline shaft with plane bearing; Described roll adjustment drive lead screw is arranged on the top of crossbeam, and the one end connects available handwheel adjustment by gear with gear, and the other end is fixed on the boring anchor of outermost end with nut; Be provided with the location in the outer end of described tooth bar converter and regulate fixture.The utility model structural design is fairly simple, manipulates more conveniently, and machining accuracy is than higher, working (machining) efficiency is significantly improved than old-fashioned drilling machine, can not produce inclined to one side hole, locate defectives such as inaccurate, can reduce production costs significantly, reduce workman's production, labour intensity.

Fig. 3 is the utility model side view

In the drawings: 1, fixture is regulated in lathe bed 2, crossbeam 3, case 4, location drill bit 5, retaining mechanism 6, spline shaft 7, roll adjustment spline shaft 8, roll adjustment drive lead screw 9, bevel gear 10, tooth bar converter 11, tooth bar 13, scale 14, spline silk braid 15, junction of the edges of two sheets of paper sieve silk 16, boring anchor 17, plane bearing 18, gear 19, handwheel 20, nut 21, location

The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing, in the drawings, the utility model multiple-head adjustable row-hole drilling machine is made up of lathe bed 1, crossbeam 2, case 3, location drill bit 4, retaining mechanism 5, it is characterized in that: be respectively arranged with spline shaft 6, roll adjustment spline shaft 7, roll adjustment turn-screw 8 in the crossbeam 2; Described spline shaft 6 is provided with several bevel gears 9 and links to each other with drill bit respectively, is provided with tooth bar converter 10 at the middle part of location drill bit 4, is connected with second drill bit by tooth bar 11, is provided with scale 13 on the top of location drill bit 4; Described roll adjustment spline shaft 7 is provided with several spline silk braids 14, and each spline silk braid 14 usefulness junction of the edges of two sheets of paper sieve silk 15 is fixed on the boring anchor 16, and an end of described boring anchor 16 is fixed on the roll adjustment spline shaft 7 with plane bearing 17; Described roll adjustment drive lead screw 8 is arranged on the top of crossbeam 2, and the one end connects available handwheel 19 by gear to be adjusted with 18 gears, and the other end is fixed on the boring anchor 16 of outermost end with nut 20; Be provided with the location in the outer end of described tooth bar converter 10 and regulate fixture 21.During concrete enforcement, multiple-head adjustable row-hole drilling machine, can adjust the distance between machining hole and the hole as required arbitrarily, by being arranged on the scale on the drill bit 4 of location, distance between the control machining hole, regulate the distance that fixture 21 is adjusted between two drill bits by adjusting the location during adjustment, and according to the adjusting arbitrarily of scale 13 dos, along with moving of tooth bar 11, driving second boring anchor moves, and be arranged on spline silk braid 14 on the roll adjustment spline shaft 7 in the crossbeam 2 because of being fixed on the boring anchor 16 with junction of the edges of two sheets of paper sieve silk 15, along with moving of boring anchor 16, the active force of the front end of spline silk braid 14 will act on the plane bearing 17 of the boring anchor in front, moves forward thereby promote the boring anchor in front.Identical therewith, form circulation.The boring anchor of back with active force push to the boring anchor of front, all along roll adjustment drive lead screw 8 to front slide, the distance of being slided just in time equates with required roll adjustment distance.When adjusting to desired location, the retaining mechanism 5 that is arranged on crossbeam 2 tops locked successively get final product.When work is finished, reset can be by handwheel 19 rotation, with the nut 20 that is arranged on roll adjustment drive lead screw 8 tops along screw mandrel with the boring anchor of outermost to pulling back, drive remaining boring anchor and be recovered to the home position.
