Abstract
The utility model discloses a split type lathe spindle case, including be equipped with the shaft hole the box, establish reach the telescopic main shaft in the shaft hole in the box, the box is mainly formed by last main shaft box and lower main shaft box two parts combination, upward be equipped with the semicircle orifice that makes up into the shaft hole on main shaft box and the lower main shaft box respectively. The utility model discloses a by the last main shaft box and the lower split type box of main shaft box body combination structure, can eliminate integral box because machining's result causes the clearance that sleeve that the deviation led to the fact telescopic main shaft is packed into and can be produced in the shaft hole of headstock, and then eliminate high -speed when rotatory the beating of production of main shaft to improve the precision of main shaft and the processingquality of product. The utility model discloses be applicable to very much the numerical control lathe of high rotational speed, high accuracy.
Description
Technical field
The utility model belongs to lathe, especially relates 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.
Utility model content
The purpose of this utility model is to provide a kind of split type Lathe Spindle Box that can improve processing precision of products.
The technical scheme realizing the utility model object is:
The split type Lathe Spindle Box that the utility model provides, 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.
The beneficial effects of the utility model:
The utility model 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 utility model is highly suitable for high rotating speed, high-precision numerically controlled lathe.
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in Fig. 1 AA to sectional view.
Detailed description of the invention
See Fig. 1, Fig. 2, the split type Lathe Spindle Box that the utility model provides, 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.
