Abstract
A linearly distributed multi-drill comprises an input shaft, a connection sleeve, a shell, drill bits and a spindle, wherein the drill bits are fixedly mounted at the bottom of the spindle; a taper handle at the upper end of the input shaft is plugged into a taper hole of the drilling spindle, and the taper face of the taper handle and the taper face of the taper hole are in matched contact to transmit torque; the connection sleeve and a feeding sleeve of a drilling tool are matched and tightly locked; the shell is arranged at the bottom of the connection sleeve; the bottom of the input shaft is fixedly connected with an input gear; the input gear is in external engaged transmission with upper gears of two duplicate gears; a lower gear of each duplicate gear is in external engaged transmission with two spindle gears at the same time, the four spindle gears are distributed on the same straight line, and the bottom of each spindle gear is fixedly provided with one drill bit. The functions of a main driving and feeding system of a prior drill are fully utilized, the structure of the multi-drill is simplified, and the manufacturing cost is reduced; multiple holes in the same straight line are machined at the same time, and accordingly the machining efficiency is improved.
Description
Technical field
The present invention relates to drill press parts technical field, particularly a kind of can the multi-drill in the simultaneously multiple hole arranged in a straight line of drilling.
Background technology
Refrigerating machine has cooling tube part as shown in Figure 1, pipe diameter 30mm, and being uniformly distributed the linear distributing diameter of 2 row at about length 1000mm is the aperture of 1-1.5mm, and hole count is close to 200.Process this some holes with single-spindle drilling machine, labour intensity is large, efficiency is low; As manufactured numerical control drilling machine processing, separate unit also can not meet the demands, and also there is the problems such as equipment volume is large, input is high.Manufacture and design multi-drill and then can overcome above shortcoming, improve working (machining) efficiency, reduce costs.
Summary of the invention
For overcoming problems of the prior art, the invention provides a kind of multi-drill of lineal layout, carrying out the porous processing be located along the same line simultaneously, improve working (machining) efficiency, control process equipment volume, reduce input cost and processing cost.
The present invention solves the technical scheme that its technical problem takes: the multi-drill of this kind of lineal layout, comprise power shaft, adapter sleeve, housing, drill bit and main shaft, drill bit is fixedly installed in the bottom of main shaft, it is characterized in that: the upper end taper shank of described power shaft inserts in drill press spindle taper hole, both cone match contact transmitting torques, adapter sleeve coordinates with the feeding sleeve of drilling machine and locks, housing is had in the bottom of adapter sleeve, the bottom of described power shaft is fixedly connected with input gear, the first line of a couplet gear external toothing transmission of described input gear and two duplicate gears, the second line of a couplet gear of each duplicate gear simultaneously with two mainshaft gear external toothing transmissions, and four mainshaft gear distributions on the same line, a drill bit is all fixed with bottom each mainshaft gear.
Further, four described main shafts are connected with housing by bearing, and main shaft is connected with bearing inner race, and bearing outer ring is fixedly connected with housing.
Further, two described dual gear structures are measure-alike, and two duplicate gears are positioned at the both sides of the straight line that four mainshaft gears are formed.
Further, this multi-drill can be used for common desktop drilling machine.
To sum up, the beneficial effect of technique scheme of the present invention is as follows:
Make full use of original equipment main transmission and feed system function, simplify multi-drill structure, reduce manufacturing cost; Porous processing is carried out to the hole be on same straight line simultaneously, improve working (machining) efficiency.

Detailed description of the invention
Be described in detail to characteristic sum principle of the present invention below in conjunction with accompanying drawing 1-5, illustrated embodiment, only for explaining the present invention, not limits protection scope of the present invention with this.
As shown in Figure 2-5, a kind of multi-drill of lineal layout of this disclosure of the invention, comprise power shaft 1, adapter sleeve 2, housing, drill bit 7 and main shaft 6 etc., wherein drill bit is fixedly mounted on the bottom of main shaft.The upper end of described power shaft is taper shank shape, and taper shank inserts in the taper hole of drill press spindle, contacts transmitting torque by taper shank with taper hole cone match.Adapter sleeve 2 coordinates with the feeding sleeve of drilling machine and locks, and has housing in the bottom of adapter sleeve, and the feeding sleeve do not rotated due to drilling machine and adapter sleeve 2 are locked together, so this device case does not rotate, main shaft 6 and housing can relatively rotate.
The bottom of described power shaft 1 is fixedly connected with by key with input gear 3, and the first line of a couplet gear external toothing transmission of described input gear and two duplicate gears 4, in order to prevent duplicate gear from interfering, the diameter of input gear is greater than the diameter of the first line of a couplet gear of duplicate gear.The second line of a couplet gear of each duplicate gear 4 simultaneously with two mainshaft gear 5 external toothing transmissions, and four mainshaft gears 5 distribute on the same line, are all fixed with a drill bit 7 bottom each mainshaft gear 5.Two described dual gear structures are measure-alike, and two duplicate gears are positioned at the both sides of the straight line that four mainshaft gears 5 are formed, to ensure the balance of this structure.Four described main shafts are connected with housing by bearing, and main shaft is connected with bearing inner race, and bearing outer ring is fixedly connected with housing.This multi-drill can be used for common desktop drilling machine.
During work, drilling machine power drive power shaft 1 rotates, and input gear 3 drives two duplicate gears 4 simultaneously, the second line of a couplet gear of each duplicate gear is meshed with two mainshaft gears 5 simultaneously, on the same line, mainshaft gear 5 rotates, and can realize bit in four main shaft distributions.Feed system still utilizes drilling machine original function, and when namely manually making feeding sleeve move down, drive whole device to move down, four drill bits process 4 holes simultaneously.Due to the restriction of bearing diameter size, in the design, the distance of adjacent two drill bits is corresponding with the pitch-row in hole to be processed, then coordinates drill jig to use, can time processing porous, greatly improves working (machining) efficiency.Make full use of original equipment main transmission and feed system function, simplify multi-drill structure, reduce manufacturing cost.
Above-described embodiment is only the description carried out the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; relevant technical staff in the field, to various distortion of the present invention and improvement, all should expand in the determined protection domain of claims of the present invention.
