Abstract
The utility model discloses a spindle box of a numerically controlled lathe with a waterproof structure. The spindle box comprises a box body, a spindle, a front end cover, a bearing and a bearing distance sleeve, wherein the spindle is arranged inside the box body through the front end cover, the bearing is matched with the spindle in a static mode through the bearing distance sleeve, a waterproof cover cap is arranged outside the front end cover, one end of the waterproof cover cap is matched with the spindle in a dynamic seal mode, and the other end of the waterproof cover cap is connected with the box body of the spindle box in a sealing mode. According to the spindle box, the external of the box body is provided with the waterproof cover cap and the waterproof cover cap and a convex shoulder of a spindle head of the spindle are matched in a dynamic seal mode through a dynamic and static combined composite sealing matching structure to block entering of the water vapor; the waterproof cover cap and the box body of the spindle box are matched in an elastic seal mode; and the waterproof cover cap enables the spindle head of the spindle to be completely sealed and the outer edge of the spindle is provided with a diversion conical surface to enable water not to permeate into the spindle box even if the water is in contact with the spindle to cause gasification. The spindle box of the numerically controlled lathe and with the waterproof structure has the advantages of being simple in structure, low in machining cost and reliable in seal, ensuring the usage safety of a machine tool, extending the service life of the machine tool and reducing the production costs.
Description
Technical field
The utility model belongs to the numerically controlled lathe technical field, is specifically related to a kind of spindle of numerical control lathe case with waterproof construction.
Background technology
Numerically controlled lathe is a kind of high accuracy, high efficiency automated machine tool, is equipped with multistation cutter tower or power cutter tower, has improved the machine tooling performance greatly, but as complex parts such as processing linear cylinder, oblique line cylinder, circular arc and various screw thread, groove, worm screws.The high-speed main spindle of numerically controlled lathe is its core component, because turning adds man-hour and often can use water, water can be splashed to the high-speed main spindle position, though the high-speed main spindle place prevent the intrusion of sealing by some sealing results or water-proofing treatment, its waterproof construction is also unreliable; In the operation process, the bearing place temperature of high-speed main spindle raises, and adverse influence is brought to the normal operation of main shaft in the water laggard main shaft inside of going into of gasifying herein.For this reason, developing a kind of spindle of numerical control lathe case with waterproof construction, is very favorable for the usefulness of giving full play to Digit Control Machine Tool.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, the spindle of numerical control lathe case with waterproof construction of low processing cost.
The purpose of this utility model is to realize like this, casing, main shaft, drive end bearing bracket, bearing, bearing spacer, described main shaft is arranged in the casing by drive end bearing bracket, bearing is by bearing spacer and main shaft stationary fit, it is characterized in that: described drive end bearing bracket arranges the bucker lid outward, waterproof cover cap one end cooperates with the main shaft movable sealing, and the other end and main shaft casing are tightly connected.
The utility model casing arranges bucker lid outward, and by dynamic and static in conjunction with the compound seal fit structure, anti-cover water cover cooperates with the movable sealing of main shaft spindle nose convex shoulder, obstruct steam enters; Adopt elastic packing to cooperate between waterproof cover cap and the main shaft casing.The waterproof cover cap is the spindle nose complete closed of main shaft, and its main shaft outer rim also is provided with the water conservancy diversion conical surface, even water contacts generating gasification with main shaft, also can not infiltrate main spindle box.Simple in structure, the low processing cost of the utility model, sealing is reliable, guarantees the use safety of lathe, prolongs its service life, reduces production costs.
