Abstract
The invention discloses a split type lathe spindle box which comprises a box body provided with a spindle hole and a sleeve type spindle which is arranged in the box body and the spindle hole, wherein the box body is mainly formed by combing an upper spindle box body and a lower spindle box body; semicircle orifices which can constitute the spindle hole are respectively formed in the upper spindle box body and the lower spindle box body. According to the split type lathe spindle box provided by the invention, the split type box body having the upper spindle box body and the lower spindle box body combined structure is adopted, so that a clearance, which is caused by deviation resulting from mechanical processing of an integral type box body, generated when a sleeve of the sleeve type spindle is put into the spindle hole of the spindle box is eliminated so as to further remove bounce generated when the spindle rotates at a high speed, thereby improving the precision of the spindle and the processing quality of a product. The split type lathe spindle box is especially suitable for a digital controlled lathe which has high rotation speed and high precision.
Description
Technical field
The invention belongs to lathe, especially relate to a kind of split type Lathe Spindle Box.
Background technology
Now, Lathe Spindle Box loads the axial aperture structure of sleeve-type main shaft is all overall.Because the result of machining causes, the internal diameter size of main spindle box axis hole and the sleeve outer diameter size of sleeve-type main shaft all can have certain deviation, and this deviation causes in the axis hole of the sleeve of sleeve-type main shaft loading main spindle box can produce certain gap.Such as: main spindle box internal diameter size is
, the sleeve outer diameter of sleeve-type main shaft is
, just produce gap between them, maximal clearance can to 0.05mm.This gap reduces the precision of main shaft, will produce and beat, affect the machining accuracy of product during main shaft High Rotation Speed.
Summary of the invention
The object of this invention is to provide a kind of split type Lathe Spindle Box that can improve processing precision of products.
The technical scheme realizing the object of the invention is:
Split type Lathe Spindle Box provided by the invention, comprise be provided with axis hole casing, be located in described casing and sleeve-type main shaft in axis hole; Described casing combines primarily of upper main spindle box body and lower main axis casing two parts, and described upper main spindle box body and lower main axis casing are respectively equipped with the semicircle axis hole being combined into axis hole.
By securing member, described sleeve-type main shaft is fastened between upper main spindle box body and lower main axis casing between described upper main spindle box body and lower main axis casing.
Combined by fixing structure between described upper main spindle box body and lower main axis casing.
Certain interval is left between the semicircle axis hole of described upper main spindle box body and the semicircle axis hole of lower main axis casing.
The width in described gap is between 0.03mm to 0.05mm.
Alignment pin is provided with between described upper main spindle box body and lower main axis casing.
Beneficial effect of the present invention:
The present invention adopts the Split type box body by upper main spindle box body and lower main axis box body combinations structure, can eliminate monoblock type casing due to the result of machining causes deviation to cause the sleeve of sleeve-type main shaft to load the gap that can produce in the axis hole of main spindle box, and then beating of producing when eliminating main shaft High Rotation Speed, thus improve the precision of main shaft and the crudy of product.
The present invention is highly suitable for high rotating speed, high-precision numerically controlled lathe.
Technical scheme of the present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 be in Fig. 1 AA to sectional view.
Detailed description of the invention
See Fig. 1, Fig. 2, split type Lathe Spindle Box provided by the invention, comprise be provided with axis hole D casing, be located in described casing and sleeve-type main shaft 3 in axis hole; Described casing combines primarily of with the upper main spindle box body 1 of fixing structure Z and lower main axis casing 2, and described upper main spindle box body 1 and lower main axis casing 2 are respectively equipped with the semicircle axis hole being combined into axis hole.During assembling, by fixing structure Z by upper main spindle box body 1 with lower main axis casing is 2-in-1 is fitted together, and bore axis hole D together; Main spindle box body 1 and the contact surface C of lower main axis casing 2 on axis hole both sides in appropriateness reconditioning; After loading sleeve-type main shaft 3, with screw 4, sleeve-type main shaft 3 is fastened between main spindle box body 1 and lower main axis casing 2 between upper main spindle box body 1 and lower main axis casing 2, with the gap between the semicircle axis hole removing sleeve-type main shaft 3 and upper main spindle box body 1 and lower main axis casing 2; Between the semicircle axis hole and the semicircle axis hole of lower main axis casing 2 of upper main spindle box body 1, leave certain interval b, the width of best clearance b is between 0.03mm to 0.05mm; After inspection main shaft precision reaches requirement, between upper main spindle box body 1 and lower main axis casing 2, squeeze into alignment pin 5.
Adopt the main spindle box physical efficiency of above-mentioned split-type structural effectively to eliminate sleeve-type main shaft and be arranged on the gap formed because of machining tolerances in main spindle box body, also eliminate because this gap beating of making main shaft produce when High Rotation Speed, the due precision of main shaft can be ensured.
Claims (6)
1. a split type Lathe Spindle Box, comprise be provided with axis hole casing, be located in described casing and sleeve-type main shaft in axis hole; It is characterized in that described casing combines primarily of upper main spindle box body and lower main axis casing two parts, described upper main spindle box body and lower main axis casing are respectively equipped with the semicircle axis hole being combined into axis hole.
