Description
Technical field
The utility model relates to a kind of vertical drilling spindle case sealing configuration, belongs to vertical drilling machine technical field.
Background technique
Vertical drilling machine, as the one of drilling machine, is also more common metal-cutting machine tool, is widely used, and the feature that precision is high is suitable for batch process, is usually used in the hole of machine-building and the medium and small workpiece of repair factory process.Existing vertical drilling machine is everlasting and is contained butter in casing and lubricate, and choose butter lubricating system and mainly well can not realize sealing based on existing main spindle box body, butter lubrication also can exist the problem of lubrication effect difference simultaneously.Therefore, study a kind of good sealing effect, can just seem important with the good lubrication realizing transmission part in main spindle box body by splendid attire machine oil.
Summary of the invention
The technical problems to be solved in the utility model: a kind of vertical drilling spindle case sealing configuration is provided, sealing configuration is reliable, can splendid attire machine oil to realize good lubrication, to overcome the deficiencies in the prior art.
Technical solutions of the utility model:
A kind of vertical drilling spindle case sealing configuration, comprise main shaft, main spindle box body and tooth bar, main spindle box body is enclosed within main shaft, and tooth bar is arranged on below main shaft; In main spindle box body, be provided with I axle, II axle and III axle, I axle, II axle and III axle are fixed in main spindle box body successively by bearing, upper ball cover, step, and upper ball cover is arranged on headstock and covers, and step is arranged on bottom main spindle box body; I axle, II axle, connected by driving gear between III axle and main shaft, I axle is connected with motor; Be placed on driving gear on main shaft with between main shaft for key is connected, and the upper end of this driving gear is connected with main spindle box body by two roller bearings; Described main spindle box body is connected with the lower end outside of the driving gear be fixed on main shaft with two outside framework oil seals by oil sealing base, and oil sealing base is fixed on main spindle box body by oil seal gasket and screw; Seal ring is provided with between described two roller bearings be installed between main spindle box body and main shaft upper transfer gear; It is transition fit between described step for fixing I axle, II axle and III axle and main spindle box body.
The described step surface for fixing I axle, II axle and III axle scribbles silica gel, further can improve sealing effect.
Be provided with seal ring between described upper ball cover and main shaft case lid, sealing effect is safe and reliable.
Be provided with outside framework oil seal between the I axle upper end that described same motor connects and main shaft case lid, machine oil can be made unlikely from I axle upper end outflow.
The beneficial effects of the utility model:
The utility model by arranging two outside framework oil seals between main spindle box body and main shaft upper transfer gear, and corresponding oil sealing base is set, oil sealing base is fixed on main spindle box body by sealing gasket and screw, and this kind of mode of structure can ensure the sealing effect between main shaft and main spindle box body; Adopting transition fit mode for fixing between the step of I axle, II axle and III axle and main spindle box body simultaneously, also can realize good sealing effect; Seal ring is set being installed between main spindle box body and main shaft upper transfer gear two bearings, the balance of sealing and bearing lubrication can be taken into account.The utility model structure is simple, and sealingly secure is reliable, can existing butter be replaced to realize better lubrication by splendid attire machine oil, can promote the use of on drilling machine.
