Abstract
The utility model relates to a waterproof structure of a lathe main shaft end, which comprises a main shaft and a front end cover, wherein the front end cover is sleeved on the main shaft, the main shaft is integrally molded by a large-diameter section on the front end and a small-diameter section on the tail end, the front end cover is connected with the joint of the large-diameter section and the small-diameter section, a saw-shaped tooth is arranged on the position of the large-diameter section corresponding to a radial surface of the front end cover, the front end cover is provided with a groove with a pitch, and the sharp part of the saw-shaped tooth is arranged to be opposite to the groove; and the vertical lower position of the front end cover is provided with a hole which is communicated with the groove. Due to the adoption of the waterproof structure of the lathe main shaft end, cutting liquid can be effectively prevented from flowing into a main shaft box through a matching gap between the main shaft and the front end cover, a main shaft bearing can be avoided to damage because of being rusted by water, and the stability of the lathe precision can be guaranteed; the service life is improved, and the additional expense because of the frequent replacement of the main shaft bearing can be reduced; and the structure is simple, the production cost is low, and the application effect is good.
Description
(1) technical field
The utility model relates to the lathe auxiliary equipment, especially a kind of waterproof construction of lathe spindle end.
(2) background technology
At present, all kinds of lathes need the cutting fluid of big flow directly to be punched on cutter and the workpiece when the high-rate cutting workpiece, can take away the heat that strong cutting produced because of cutter like this, avoid the thermal deformation of workpiece, reduce the degree of wear of cutter.Carrying out the washing away in the process of cutting fluid, a large amount of cutting fluids can be splashed on the main shaft of lathe, enters the front-end of spindle bearing, causes the damage of main shaft bearing, and then has influenced the precision of lathe.
(3) summary of the invention
Wash away the shortcoming that cutting fluid enters the front-end of spindle bearing in the process in order to solve existing numerically controlled lathe carrying out cutting fluid, the utility model provides a kind of waterproof construction, can effectively avoid the damage of cutting fluid, improve the precision and the service life of lathe main shaft bearing.
For this reason, the utility model is taked following technical scheme:
A kind of waterproof construction of lathe spindle end, include main shaft and drive end bearing bracket, described drive end bearing bracket can be located on the main shaft, described main shaft is by one-body molded composition of reduced diameter section of the enlarged diameter section and the tail end of front end, described drive end bearing bracket is connected the junction of enlarged diameter section and reduced diameter section, the sagittal plane position of the corresponding drive end bearing bracket of described enlarged diameter section is provided with saw type tooth, and described drive end bearing bracket is provided with the groove of band gradient, the relative groove arrangement in tip of described saw type tooth; The vertical lower position of described drive end bearing bracket is provided with the hole that is communicated with groove.
Lathe is when the high-rate cutting workpiece, the cutting fluid of the big flow main shaft of flowing through, the special tooth profile of jagsaw type tooth stops, under the centrifugal action that lathe rotates at a high speed, cutting fluid is all got rid of in the groove that the front-end of spindle lid cooperates with it, go out by the orifice flow that connects with it again, can not be splashed on the main shaft of lathe, enter the front-end of spindle bearing.
Employing the utlity model has following advantage: 1, effectively stoped cutting fluid to flow in the main spindle box by the fit clearance between main shaft and the drive end bearing bracket, avoided main shaft bearing to go up rust because of intaking and damaged, guaranteed the stability of machine tool accuracy; 2, improved service life, reduced the extra charge of changing main shaft bearing because of frequent; 3, simple in structure, cost of manufacture is low, result of use good.
(4) description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A enlarged drawing.
(5) specific embodiment
With reference to Fig. 1-2, a kind of waterproof construction of lathe spindle end, include main shaft 6 and drive end bearing bracket 4, described drive end bearing bracket is set on the main shaft, described main shaft is by one-body molded composition of reduced diameter section of the enlarged diameter section and the tail end of front end, and described drive end bearing bracket is connected the junction of enlarged diameter section and reduced diameter section, and the sagittal plane position of the corresponding drive end bearing bracket of described enlarged diameter section is provided with saw type tooth 61, described drive end bearing bracket is provided with the groove 41 of band gradient, the relative groove arrangement in tip of described saw type tooth; The vertical lower position of described drive end bearing bracket is provided with the hole 7 that is communicated with groove.
Claims (1)
1. the waterproof construction of a lathe spindle end, include main shaft and drive end bearing bracket, described drive end bearing bracket is set on the main shaft, it is characterized in that: described main shaft is by one-body molded composition of reduced diameter section of the enlarged diameter section and the tail end of front end, described drive end bearing bracket is connected the junction of enlarged diameter section and reduced diameter section, the sagittal plane position of the corresponding drive end bearing bracket of described enlarged diameter section is provided with saw type tooth, and described drive end bearing bracket is provided with the groove of band gradient, the relative groove arrangement in tip of described saw type tooth;
The vertical lower position of described drive end bearing bracket is provided with the hole that is communicated with groove.
