The machine tool fixing top tip has good waterproofing effects, the service life of the fixing top tip can be prolonged, and the use safety factor of the fixing top tip can be increased.
Description
Technical field
The utility model relates to a kind of lathe stationary center.
Background technology
At present in mechanical processing industry, lathe has become the modern times and has joined machining and use the most frequent instrument in producing.Axial workpiece is being added man-hour, also need on lathe, install supporting toply,, and driving part and rotate at a high speed, cutter can conveniently be processed with the location axial workpiece.Axial workpiece has many types, and same lathe need can be located axial workpiece to top the adjusting just when the axial workpiece of processing different length.Lathe is top generally all to have two, can regulate its position for rolling center for one, and another can not regulate its position for stationary center.In some vertical machines, generally all rolling center is installed in the top, and stationary center is installed in the below, through the rotation of motor drives stationary center, make the rotation that processes raw material, so that processing.Also need aim at the processed position of raw material man-hour at any time and spray cooling fluid adding; Therefore for vertical machine; The stationary center that is positioned at the below is easy to into water and causes accessory such as internal bearings to break down or damage; Particularly be connected with the stationary center of motor, also can cause power failure after the water inlet, the serious processing personnel's that also can have influence on safety.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of lathe stationary center, and it has waterproof effect, can break down by stationary center advantage safe in utilization.
To achieve these goals; The technical scheme that the utility model adopted is: the lathe stationary center comprises the shell that is positioned on the lathe, and is installed on the top external member in the shell; Said top external member passes from the upper end hole of shell; It is characterized in that said upper end hole place is equipped with this end of shell is coated on interior umbrella cover fully, said cover center positions top external member through water-sealed bearing.
Preferably, said top external member is installed in the said shell through two axial location bearings, and said two axial location bearings are to bear axial force direction installation on the contrary.
Preferably, said shell is the right angle pipe fitting that comprises vertical tube and transverse tube; Said vertical tube is installed top external member, and transverse tube is installed motor driving shaft; Said motor driving shaft and top external member are connected transmission through the bevel gear pair of a pair of axis quadrature.
Preferably, said motor driving shaft is installed in the said shell through two axial location bearings, and
Said two axial location bearings are to bear axial force direction installation on the contrary.
Preferably, said top external member comprises sleeve pipe and rod member, and rod member is embedded in the sleeve pipe; Said bar cross section is shaped as frustum, and the inner hole section shape of said sleeve pipe is the frustum that is complementary with rod member.
The lathe stationary center of the utility model; Through pass the position of shell in top external member; A umbrella cover is installed, in this end of shell is coated on fully, a water-sealed bearing is installed between top external member and cover simultaneously; Can make stationary center have waterproof effect preferably like this; Prevent that well cooling fluid from getting into stationary center inside and damage inner body, can certainly avoid cooling fluid to get into the workman's electric shock accidents that is connected with the position of motor and causes, improved the service life and the coefficient safe in utilization of stationary center.

The specific embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
Embodiment, see shown in Figure 1:
The utility model is a kind of lathe stationary center; The lathe stationary center comprises the shell 10 that is positioned on the lathe, and is installed on the top external member 20 in the shell 10; Said top external member 20 passes from the upper end hole 11 of shell 10; It is characterized in that said upper end hole 11 places are equipped with shell 10 these ends are coated on interior umbrella cover 12 fully, said cover 12 centers position through 13 pairs of top external members 20 of water-sealed bearing.The lathe stationary center of the utility model; Through pass the position of shell 10 in top external member 20; A umbrella cover 12 is installed, in this end of shell 10 is coated on fully, water-sealed bearing 13 of installation between top external member 20 and cover 12 simultaneously; Can make stationary center have waterproof effect preferably like this; Prevent that well cooling fluid from getting into stationary center inside and damage inner body, can certainly avoid cooling fluid to get into the workman's electric shock accidents that is connected with the position of motor and causes, improved the service life and the coefficient safe in utilization of stationary center.
For top external member 20 is not moved axially at shell 10, said top external member 20 is installed in the said shell 10 through two axial location bearings 30, and said two axial location bearings 30 are to bear axial force direction installation on the contrary.In order to reduce the lathe volume, save the space, said shell 10 is the right angle pipe fitting that comprises vertical tube 14 and transverse tube 15; Said vertical tube 14 is installed top external member 20, and transverse tube 15 is installed motor driving shaft 40; Said motor driving shaft 40 and top external member 20 are connected transmission through the bevel gear pair 50 of a pair of axis quadrature.Equally for motor driving shaft 40 is not moved axially in shell 10; Make be in transmission connection more stable; Motor driving shaft 40 is installed in the said shell 10 through two axial location bearings 30, and said two axial location bearings 30 are to bear axial force direction installation on the contrary.In order to make top external member 20 be unlikely to the inwardly withdrawal of stressed back, said top external member 20 comprises sleeve pipe 21 and rod member 22, and rod member 22 is embedded in the sleeve pipe 21; Said rod member 22 cross sectional shapes are frustum, and the inner hole section shape of said sleeve pipe 21 is the frustums that are complementary with rod member 22.
The stationary center of the utility model has waterproof effect preferably, has improved the service life and the coefficient safe in utilization of stationary center.
