Description
Technical field
The invention belongs to machine tool fields, and in particular to a kind of multi-hole drill lathe axles box easy to assemble.
Background technique
Evenly distributed aperture on ring flange can be processed by multi-hole drill lathe, and multi-hole drill lathe is mostly special plane,
The drill bit of identical quantity is set according to hole number small on ring flange, drill bit rotates respectively, all holes can be once completed the process, and
Hole perpendicularity, the position degree of processing are preferable.Axles box is multi-hole drill lathe important component, and that stretches out in multiaxis box assembly turns
Axis faces the hole for needing to bore processing on ring flange.
For axles box in disassembly process, shaft needs to be cased with bearing to be supported, reduce the friction system in motion process
Count and guarantee its rotating accuracy；As shown in Figure 1, when hole number is more, since gap is too small between shaft, and roller bearing needle-holding
There is thin and long roller, therefore radial structure is compact, when internal diameter and load-carrying ability identical as other types of bearings, outer diameter
Minimum, the supporting structure especially suitable for the size-constrained system of radially installed.Interfere in order to prevent, traditional approach is using installation side by side
Needle bearing.
But needle bearing installation is complicated, usually using auxiliary sleeve progress, when installation, first by table in bearing outer ring
Face is coated with lubricating grease, is close to inner surface and is placed with needle roller, and then the help roll or auxiliary sleeve that replace axle journal or bearing inner race are pushed away
The bearing inner race end face for entering in cycle hole, and the alignment of its end face being made to install axial end or be mounted on an axle, then uses press machine
Or hand hammer beats application pressure.Should be there are gap when being placed with last root needle roller, the size in gap is on the circumference of needle bearing
It is advisable with 0.5mm.Last root needle roller is squeezed cannot firmly and be loaded into, or fill a needle roller less, because when hard crowded dress, bearing meeting
Being stuck cannot rotate；When filling less, gap is excessive, and needle roller rocks and fractures when easily causing bearing operation.
For the needle bearing of 16 drill bits, a skilled worker needs the just mountable completion of 4 day time.When needle bearing is because tired
Into when leading to damage, dismounting is time-consuming more for weary damage, insufficient lubrication, pollutant.
Simultaneously as the mounting hole of the multiaxis box body where the bearing of laid out in parallel, spaced too close together, cause rigidity compared with
Difference is easily deformed and damages.
Summary of the invention
For above-mentioned deficiency present in the prior art, the technical problem to be solved by the present invention is to existing multi-hole drill lathe is more
Axle box, using the lesser needle bearing of diameter, dismounts complicated and time consumption, and the multi-axle box body of shaft installation when drill bit quantity is more
Rigidity is poor.
In order to solve the above technical problem, the present invention provides a kind of multi-hole drill lathe axles box easy to assemble, including it is shaft, preceding
Lid, fore bearing, driving gear, transmission shaft, cabinet, rear cover, drive shaft, rear bearing, driven gear,
The cabinet, rear cover, front cover are rectangle, and cross-sectional sizes are identical；The front cover, rear cover are installed by bolt respectively
In the front and back sides of the cabinet；
The rear cover is provided centrally with through hole, and the drive shaft passes through rear cover, and the drive shaft passes through shaft coupling and institute
State transmission axis connection；
The cabinet front and back sides are provided centrally with mounting hole for installing the transmission shaft, the front and back side of the cabinet
Face is respectively arranged with the mounting hole of multiple uniform annular distributions for installing the fore bearing, rear bearing, the fore bearing, rear axle
It holds and is respectively fitted over the shaft front middle part and rear portion；The shaft has more, and front end is equipped with drill bit；The adjacent shaft
The fore bearing that has, rear bearing are laterally staggered, i.e., the multiple fore bearing, rear bearing are divided into institute more than two, adjacent
Fore bearing, rear bearing are stated not at same group, and the interval before the central plane of fore bearing described in two groups, rear bearing is more than bearing
Thickness；
The cyclic annular through hole with quantity identical on the cabinet and position is provided on the front cover, the shaft passes through institute
State the through hole on front cover；
The driving gear is installed in the middle part of the transmission shaft, the driven gear, the master are installed in the shaft
Moving gear is engaged with the driven gear, and the drive shaft can drive the transmission shaft, and more shafts is driven to rotate synchronously.
Further, the lateral shift of component in order to prevent, the fore bearing, driven gear are equipped between rear bearing
The spacer on the outside of the shaft is covered, the spacer is tubular.
Further, the fore bearing includes two deep groove ball bearings, and the rear bearing includes a deep groove ball bearing.
Further, in order to reduce the thickness of the wall box, material cost is saved, further includes transition disc, the mistake
It crosses centered on disk and has the cylindrical body of blind hole, the transition disc quantity is identical as shaft quantity, the latter half of close-fitting of transition disc
Or it is welded in the mounting hole of the cabinet front wall, the blind hole close-fitting of the front axle bearing outer-ring and the transition disk center.
Further, the variable speed frequency of the drive shaft, the revolving speed of the drive shaft are 85rpm, the shaft revolving speed
For 148rpm.
Further, the shaft has 16.
The working principle of the invention:
It is different from the axles box of a fairly large number of multi-hole drill of conventional drill, bearing laid out in parallel can only be using installation, disassembly
Relatively complicated needle bearing, while when bearing is mounted on multiaxis box body, the gap between bearing outer ring is smaller, leads to multiaxis
Box body mounting hole is too close to support section is too small, and rigidity is poor.The present invention uses the design of the laterally staggered distribution of bearing,
It installs transition disc additional, increases the support section on multiaxis box body, rigidity improves, while can be conventional deep using what is be relatively large in diameter
Ditch ball bearing reduces cost, and dismounts more convenient.For the needle bearing of 16 drill bits, a skilled worker needs 4 day time
Mountable completion.And after the conventional deep groove ball bearing for using bearing to be interspersed, it is only necessary to which time half a day can be installed.
The beneficial effects of the present invention are:
For the present invention using the bearing being interspersed, disassembly is more convenient, and improves the rigidity of mounting structure for rotating shaft.
