Abstract
The invention discloses a precise machine tool fixture. The precise machine tool fixture comprises a fixed support surface and a movable support surface mounted on a machine tool; a machine tool main shaft hole is formed in the fixed support surface; a mandrel is mounted in the machine tool main shaft hole; a boss is arranged at the middle part of the mandrel; an expansion sleeve is mounted at the other end of the mandrel; the inner edge of the expansion sleeve and the outer surface of the mandrel are matched in a conical surface manner; a spring ring is mounted on the expansion sleeve; the movable support surface is fixed on a slide block; an ejector rod is mounted on the movable support surface; a locking boss is mounted at the top end of the ejector rod; and an annular clamping groove is formed in the neck part of the locking boss. The precise machine tool fixture is mainly used for machining pipe sleeve type parts, fixes pipes by extruding and expanding the pipes through the expansion sleeve to increase the radial area after direct clamping of the pipes, and has the advantages of simple structure, convenience for operation and high positioning precision.
Description
Technical field
The present invention relates to field of machining, be specially a kind of precision fixture of machine tool.
Background technology
In machine components are processed, the processing of a lot of cover parts can be touched, some cover parts is very high for the required precision of processing, during often through common clamping with three-jaw chuck workpiece, position accuracy demand can not be met, and make workpiece produce moderate finite deformation, the precision of impact processing, cause that workpiece is scrapped. For the processing of part cover parts, use traditional scroll chuck can not meet the demand of production and processing.
Summary of the invention
Technical problem solved by the invention is in that to provide a kind of precision fixture of machine tool, with the problem solving to propose in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of precision fixture of machine tool, including the fixed support surfaces being arranged on lathe and movable supporting face; Described fixed support surfaces is provided with machine tool chief axis hole, and machine tool chief axis hole is built with mandrel; Described mandrel mid portion is provided with boss, and the other end of mandrel is equipped with expansion sleeve, and the inward flange of expansion sleeve and the outer surface of mandrel are cone match; Equipped with turn on described expansion sleeve; Described movable supporting face is fixed on slide block, equipped with push rod on movable supporting face; The top of described push rod is equipped with locking boss, and the cervical region of locking boss is provided with annular slot.
Further, described locking boss material is rubber, and after extruding, radial dimension becomes big.
Further, the top of described expansion sleeve is provided with a circle tongue, and tongue is supporting with draw-in groove.
Further, described slide block is fixed on machine tool guideway, and slide block is provided with brake.
Present invention is mainly used for processing pipe sleeve workpiece, directly increase radially area after expansion sleeve extrusion expansion by utilizing after pipe fitting clamping, thus fixing pipe fitting, there is simple in construction, the advantage that easy to operate, positioning precision is high.

Fig. 1 is present configuration schematic diagram;
Fig. 2 is effect plays figure of the present invention.
Detailed description of the invention
In order to make realizing technological means, creation characteristic, reaching purpose and effect and be easy to understand of the present invention, below in conjunction with being specifically illustrating, the present invention is expanded on further.
As shown in Figure 1-2, a kind of precision fixture of machine tool, including the fixed support surfaces 1 being arranged on lathe and movable supporting face 2; Described fixed support surfaces 1 is provided with machine tool chief axis hole, and machine tool chief axis hole is built with mandrel 3; Described mandrel 3 mid portion is provided with boss 4, and the other end of mandrel 3 is cone match equipped with the outer surface of expansion sleeve 5, the inward flange of expansion sleeve 5 and mandrel 3; Equipped with turn 6 on described expansion sleeve 5; Described movable supporting face 2 is fixed on slide block 7, equipped with push rod 8 on movable supporting face 2; The top of described push rod 8 is equipped with locking boss 9, and the cervical region of locking boss 9 is provided with annular slot 10.
Further, described locking boss 9 material is rubber, and after extruding, radial dimension becomes big.
Further, the top of described expansion sleeve 5 is provided with a circle tongue 11, and tongue 11 is supporting with draw-in groove 10.
Further, described slide block 7 is fixed on machine tool guideway, and slide block 7 is provided with brake.
In practical operation, when sleeve workpiece is arranged on the outer round surface of expansion sleeve 5, extruded to expansion sleeve 5 by push rod 8, the outer round surface of expansion sleeve 5 radially becomes big, because turn 6 produces compression stress, and because workpiece radial force in the course of processing, more than axial force, ensures that sleeve workpiece is securedly mounted to the outer round surface of expansion sleeve 5 more; When sleeve workpiece changed by needs, it is only necessary to brake on slide block 7 is pulled open and slides backward.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described. Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention. The claimed scope of the present invention is defined by appending claims and equivalent thereof.
