Description
Technical field
The utility model relates to machining apparatus fields, specifically horizontal milling machine spindle box.
Background technique
Milling machine is a kind of widely used lathe, and the common structure of bed-type milling machine therein has vertical knee-type milling machine and vertical ten thousand
Energy milling machine, for vertical universal milling machine due to needing rotation head manually when work, working efficiency is low, is not approved by user；
And the bed-type milling machine working ability with vertical and horizontal one is strong, work efficiency is high, and market prospects are good.Chinese utility model patent
CN103273089B discloses a kind of vertical sleeping integral type spindle box, including cabinet, is fixedly installed with power motor, cabinet on cabinet
Interior relative rotation is equipped with I transmission shaft, vertical spindle and horizontal main axis, and I transmission shaft is gear shaft structure, I transmission shaft and power
Motor driven is connected, and I transmission shaft is arranged in parallel with vertical spindle, and vertical spindle and horizontal main axis are space crossed shape peace in 90 °
It fills, relative rotation is equipped with II transmission shaft, III transmission shaft and IV transmission shaft in cabinet, can be the case where being changed without spindle box
Under, vertical processing and horizontal processing are completed, transfer motion power is strong, and cutting power is good, reduce kinetic equation loss, and use is safe, but
Do not overcome disadvantage existing in the prior art yet: the spacing fixed between gear on axis falls short of, former in shifting slide gear sliding
A pair of engagement is not yet completely disengaged, and another pair gear will enter engagement；Drawn due to determine improper of the number of teeth or transmission ratio
It plays gear and adjacent axis is interfered；So that axis is generated axial float because of the axially position of axis deficiency, or cause to interfere because of overdetermination position,
Cause machining accuracy inadequate.
Utility model content
The technical problem to be solved by the utility model is to provide horizontal milling machine spindle boxes, to solve to exist in the prior art
Defect.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
Horizontal milling machine spindle box, including cabinet, are equipped with belt wheel above cabinet, and the belt wheel drives main axis, on main shaft
Key drive three transmission shafts below main shaft successively to carry out power transmission, wherein close to the transmission shaft before, during and after it of main shaft
It is respectively arranged with tapered roller bearing one, Biserial cylindrical roller bearing one, tapered roller bearing two, the transmission shaft of bottom passes through
Cabinet simultaneously passes through end cap seal outside the enclosure；And its middle part and rear portion are respectively equipped with cylinder roller bearing and double-row cylindrical roller axis
Hold two.
Further, there is felt collar to enhance leakproofness for the end cap and between centers.
Further, the belt wheel drives driving shaft rotation by the deep groove ball bearing in sleeve, and driving shaft is located at cabinet
Interior one end is connect by axle sleeve with cabinet.
Further, the gear two sides on intermediate transmission shaft are provided with circlip, prevent gear from moving axially
Also have the function of alleviating external impact force simultaneously, improves the service life of gear.
The beneficial effects of the utility model are: by being equipped with cylinder roller bearing and tapered roller bearing and each in cabinet
A transmission shafts connection, may be implemented the accurate positioning to transmission shaft, improves and is driven accuracy, while tapered roller bearing one,
Two can reduce radial load, prevent axis from overdetermination position or play occur, improve milling machine machining accuracy.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
The reference numerals are as follows:
1, cabinet, 2, cylinder roller bearing, 3, end cap, 4, felt collar, 5, tapered roller bearing one, 6, belt wheel, 7, deep-groove ball

Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, horizontal milling machine spindle box, including cabinet 1, it is equipped with belt wheel 6 above cabinet 1, the belt wheel 6 drives master
Axis rotates, and the key 9 on main shaft drives three transmission shafts below main shaft successively to carry out power transmission, wherein close to the transmission of main shaft
Axis is respectively arranged with tapered roller bearing 1, Biserial cylindrical roller bearing 1, tapered roller bearing two before, during and after it
12, the transmission shaft of bottom passes through cabinet 1 and is sealed outside cabinet 1 by end cap 3；And its middle part and rear portion are respectively equipped with cylinder
Roller bearing 2 and Biserial cylindrical roller bearing 2 14；
Further, the end cap 3 between centers there is felt collar 4 to enhance leakproofness；
Further, the belt wheel 6 drives driving shaft rotation by the deep groove ball bearing 7 in sleeve 8, and driving shaft is located at case
One end in body 1 is connect by axle sleeve 10 with cabinet 1；
Further, the gear two sides on intermediate transmission shaft are provided with circlip 13, prevent gear from moving axially
While also have the function of alleviate external impact force, improve the service life of gear；
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
