Description

Combined multiple-spindle honing, drilling, reaming and toothing device

For complying with a large amount of economization production, from the boring processing of traditional unit, single axle, process by the boring of progressive multiaxial type up till now and tapping for drilling machine, and present multiaxial type drilling-tapping machine mainly is distinguished into spindle nose:

(1) fixed cluster head:

As shown in Figure 4, it is on spindle nose, with motor transmission one driving shaft (14), makes the terminal linked gear (15) of driving shaft (14) drive each driven shaft (41), because the terminal gears engaged of each driven shaft (41) makes each driven shaft (41) rotation; Because of driven shaft (41) directly passes holder (7), holder is early fixing with each cutter shaft (4), only treats driven shaft (41) transmission, just the cutter in the cutter shaft (4) can be driven, to hole or the work of tapping.

Because this kind spindle nose only can hole or tapping on certain bore position, therefore when certain produce object produced finish after, this kind formation machinery just can not use and let alone damage.With regard to the viewpoint of economic benefit, be too to waste and lack multi-functional applicability really.

(2) universal joint formula cluster head:

As shown in Figure 5, this kind universal joint formula cluster head boring tooth machine is to design at the shortcoming of fixed cluster head, still locates at driving shaft (14), does transmission with linked gear (15); It is the upper and lower intrinsic universal joint (6) that respectively connects with an expansion link (12), when adjusting seat (8) adjustment position to cooperate, but still transmission.Yet adjust seat (8) though can do adjustment on the angle, but because of cutter shaft (4) and universal joint directly articulate, only come the packing location and adjust seat (8) with dog screw (84), so cutter shaft (4) stability of transmission deficiency, and the expansion link (12) in the support (1) easily makes dirts such as dust, grease enter, and lack the noise that effectively covers between the axle transmission, therefore make operating personnel feel uncomfortable deeply.

(3) adjustable type universal joint formula cluster head:

As Fig. 6, be the stability of promotion operation and being suitable for of multiple object production, so the final drive shaft (16) of (being the universal joint under the power transmission shaft) is gone up an affixed gear under the universal joint (6) of support (1), and be meshed with it with a pinion gear (83), this gear (83) is fixed on to be adjusted on the seat (8), and coaxial with cutter shaft (4), the bite of (5) so that direct transmission cutter shaft (4) is fixed a cutting tool; Adjust seat (8) and be provided with a chute (81), pass with a location screw (84), and be fixed on the screw (71) of holder (7), adjust seat (8) so that can stablize, also extend a binding sheet (82) in the seat (8) under final drive shaft (16) gear and adjust.The characteristic of this kind structure is:

When action, final drive shaft (16) rotation when driving pinion gear (83) turn simultaneously, makes cutter shaft (4) rotation, does cutting for cutter (5) and uses.

When adjusting, then loosen dog screw (84), borrow brace (82) and the pivot joint of final drive shaft (16) and the engagement of gear (83); When make adjusting center that seat (8) can final drive shaft (16) and doing 360 ° of rotations, the arbitrfary point of gear (83) in these 360 ° adjusted, as long as be transferred to preposition, screwed in place screw (84) again, can relend the engagement of gear (83) and final drive shaft (16), cutter shaft (4) still can rotate, and cutter (5) still can cut.

This is the most advanced at present, the spindle nose of most popular multiaxial type drilling-tapping machine, but this spindle nose still has following shortcoming:

The fastening vibration that is subjected to the motor transmission of dog screw causes that loosening phenomenon is arranged, and occurs flaw and error when making a large amount of production identical product.

The support bottom lacks dust cover, causes dust, detritus to be fallen in the transmission mechanism, the rotation of influence cutting, and the transmission mechanism gear parts of dress is scrapped fully in causing.

It is isolated to lack good bottom, so that noise is big.

Still must install and use drill jig and guided mode, the position that just can make each cutter shaft gets out or the hole or the screw of tapping exact position accurately inerrably when cutting, yet, adjust with manpower, still have great error amount.

So plant the still few of difference of spindle nose of spindle nose and universal joint formula, still there is noise big, transmission mechanism is got dirty and is undermined and must measure and proofread and correct out definite cutting position with drill jig, do not exist together and only be that its spindle nose than universal joint formula has bigger adjusting and applicability.

The purpose of this utility model is to provide that a kind of improved combination type multi-shaft is warded off, bored, hinge, tapping device, to overcome the existing in prior technology shortcoming.

This kind device need not after can directly fixing, install cutter additional and cut immediately again with the foundation of drill jig as tool compensation, and can prevent that the damage of dust detritus and noise content are very low.

According to the utility model, this improved combination type multi-shaft is warded off, is bored, hinge, tapping device comprise elements such as support, localization tool plate, bearing block, cutter shaft, cutter, and cutter is fixed in the cutter shaft; Cutter shaft top bearing shaft bearing; Bearing block is fixed on the localization tool plate; This tool plate is locked on the support, wherein the localization tool plate is provided with for cutter shaft, bearing block combination and passes fixing datum hole, and the position that the corresponding work package desire of this datum hole sets when cutting, bearing block places bearing in the axis hole, fixing cutter shaft driven shaft on axis hole, and this bearing block top is passed the datum hole of localization tool plate and is fixed on the localization tool plate, it is characterized in that:

Support which is provided with alignment pin and some screws fixing for guided mode; But localization tool plate fixed bearing block, and be fixed on the support; Bearing block and cutter shaft fix as one, and run through to be fixed on the localization tool plate for the location;

By above-mentioned member, when making on the localization tool plate fixed-site bearing block according to datum hole, no longer adjusted the position of cutter shaft, so that reach the cutting of directly carrying out multiaxial type.

Bearing block (3), the upper and lower of this pedestal all is inserted in a bearing (33), central authorities' axis holes (32) then supply the driven shaft (41) of cutter shaft to fasten, and upwards penetrate the datum hole (23) of localization tool plate (2) in the lump, top is exposed on the localization tool plate (2), the through hole (31) that passes on the bearing block (3) with screw (34) is screwed on the localization tool plate (2) then, with fixing whole bearing block (3).

Cutter shaft (4), top are driven shaft (41), are pass bearing block (3); The part that directly exposes then connect solid universal joint (6) in case with expansion link (12) interlock, seat hole (42) under the cutter shaft (4) then supplies cutter (5) to penetrate, and is screwed into the chuck folder shown in interior fixed cutting tool of screw (43) (5) or the A detail drawing with hold-down screw.

When transmission (as Fig. 2), driving shaft (14) drives the expansion link (12) of upper and lower equal tool universal joint (6) with linked gear (15), and carries out cutwork by the interlock cutter (5) of driven shaft (41).

The utility model has following advantage and good effect.

Cutter shaft (4) is fixed on the bearing block (3) effectively, and bearing block (3) then is fixed on the localization tool plate (2), so the stability of cutter shaft (4) without a doubt.

Localization tool plate (2) has sealed the bottom of support (1), therefore can completely cut off power transmission shaft (12) noise, and avoid dust, the intrusion of detritus or outer of power transmission shaft oil stain.

More than 2 points, obviously overcome the shortcoming of universal joint formula spindle nose.

As previously mentioned, the characteristic of localization tool plate (2) is:

Dowel hole (21) can be for the location.

Datum hole (23) is identical with the cutting position that is cut part.

Bearing block (3) is fixing with screw (34) and localization tool plate (2).

Therefore, after finishing the workpiece processing of bore position as shown in Figure 1, when desiring to make into various workpiece as shown in Figure 3, can take out earlier one with the standard component of the identical size of localization tool plate (2) and tool dowel hole (21) and through hole (22), the position that concerns that is positioned according to workpiece is got out and the isometrical datum hole (23) in bearing block (3) top then, and getting out the screw of fixed bearing block (3) usefulness again, this moment, one pair of standard setting tool was just finished.Then unload former location tool plate (please consulting Fig. 1 and Fig. 2 simultaneously), with universal joint (6) removal between expansion link (12) and driven shaft axle (41), loosen the screw (34) of each bearing block (3), the combination of just desirable step (3) and cutter shaft (4) (this moment, cutter unloaded certainly); After treating the equal removal of each bearing block (3), loosen each screw (24) again, just localization tool plate (2) can be taken off (the localization tool plate (2) that this takes off can be kept in, in case there is identical work package desire to handle, just can install additional back immediately).Then the new localization tool plate of desiring to change (2) is loaded onto, align dowel hole (21), pack into support (1) bottom, each screw (24) of screwing on can be fixed on the localization tool plate on the support (1), plugs bearing block (3) according to the position of datum hole (23) then, and it is solid with screw (34) pin, then cutter shaft (4) is just fixing again, add at last universal joint (6) in conjunction with expansion link (12) and driven shaft (41), load onto the work that cutter (5) just can cut.

In the whole program that changes the outfit, has no technical requirement, just the work of assembly; What but concern whole cutting accuracy is:

Cutter shaft (4) must effectively and inerrably be fixed on the bearing block (3).

Datum hole (23) and through hole (31) (for the fixing hole on the localization tool plate of usefulness of screw (34)) must be precisely (can precision machined mode finish).

As long as have above necessary condition, the workpiece of any moulding no matter then, as long as cut earlier on the standard component by localization tool plate (2), cutter shaft (4) is fixing then, just can produce the cutting members of all size.

So under this kind structure:

Need not go to take a lot of trouble to adjust the position of cutter shaft (4), as long as localization tool plate (2) is errorless, all are out of question.

It is light and quick to change the outfit.

As long as anchor clamps calculate and suitable make the work package position that reclines, and cooperate the orientation with alignment pin (13) to get final product, also need not take a lot of trouble to nurse one's health anchor clamps.

Except that be applied to boring, the tapping, general special machine (as Fig. 7) also can make the pedestal on it make into as localization tool plate of the present utility model (2), boring a hole of multiaxial type then, fraising waits also to be enough to be suitable for.

In sum, the utility model really can be at the shortcoming of common structure, reasonably in conjunction with its advantage and solved its insoluble congenital shortcoming.
