Abstract
The utility model discloses a clamp center frame for a lathe. The clamp center frame comprises a semicircular center frame base, wherein a fixed clamping block is fixedly arranged at the middle part of the lower end face of the semicircular center frame base; a semicircular center frame pressing cover is arranged above the semicircular center frame base; the upper end part of one side of the semicircular center frame pressing cover is hinged to the lower end part of the corresponding side of the semicircular center frame base; the other side of the semicircular center frame pressing cover is fixed through a bolt; three supporting shafts, of which every two form an angle of 120 degrees, are distributed on the semicircular center frame base and the semicircular center frame pressing cover; operating shafts are matched in the supporting shafts in a guide manner; an operating rod fixing sleeve and an operating rod cover are arranged on the outer end part of each operating rod; supporting heads are arranged at the other ends of the operating shafts. The clamp center frame for the lathe is reasonable in structural design, easy to operate and convenient to use and is suitable for processing of most rod materials with larger outer diameters and longer lengths; the center frame base and the center frame pressing cover are made of castings, so that the clamp center frame is higher in shock absorption performance; the cooperation part cost and the technical flow are reduced.
Description
Technical field
The utility model relates to machining auxiliary equipment field, relates in particular to a kind of clamp for lathe centre frame.
Background technology
In the time of lathe processing major axis, its middle part mostly needs supplemental support, and existing auxiliary support structure is simple, a major axis just need to configure a supplemental support, therefore in single-piece work is produced, cause the height that manufactures a finished product, and at another part of processing be, need to reinstall the supplemental support being mated, its hand labor intensity is large, waste time and energy, inefficiency.
Utility model content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of clamp for lathe centre frame is provided.
The utility model is achieved through the following technical solutions:
A kind of clamp for lathe centre frame, include semicircle centre frame base, it is characterized in that: the middle part, lower surface of described semicircle centre frame base is installed with fixing fixture block, the top of described semicircle centre frame base is provided with semicircle centre frame gland, the upper end of semicircle centre frame gland one side and the bottom of semicircle centre frame base respective side are hinged, opposite side is bolted, on described semicircle centre frame base and semicircle centre frame gland, be distributed with three and be the back shaft of 120 °, in described back shaft, guiding is combined with operating axis, the outer end of described operating axis is provided with action bars fixed cover and handles bowl cover, the other end of operating axis is provided with supporting member.
On described semicircle centre frame base, be equipped with two and be the back shaft of 120 °.
Its principle is: after centre frame is fixed on lathe guide rail, handle bowl cover by manual operation, three supporting members are close on workpiece, can realize the processing of workpiece, it is simple in structure, easy to use, adopt three supporting members to support, there is good centring property, bottom is provided with fixing fixture block and can effectively centre frame be fixed on lathe, centre frame base is provided with the guide rail matching with lathe guide rail, can make centre frame move left and right on lathe guide rail, the convenient centre frame position that regulates, supporting member end face mill has sphere, match with corresponding workpiece, more stable, reliably, the workpiece of different size, only need to change corresponding supporting member, can use, for the longer bar of processing on lathe, improve working axiality, guarantee precision.
The utility model has the advantages that:
The utility model reasonable in design, simple to operate, easy to use; Be applicable to the processing of the bar that most of external diameters are large, length is grown; Centre frame base and centre frame gland adopt foundry goods manufacture, have good anti-seismic performance; Cooperation part cost and technological process etc. are reduced.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing, a kind of clamp for lathe centre frame, include semicircle centre frame base 1, the middle part, lower surface of semicircle centre frame base 1 is installed with fixing fixture block 2, the top of semicircle centre frame base 1 is provided with semicircle centre frame gland 3, the upper end of semicircle centre frame gland 3 one sides and the bottom of semicircle centre frame base 1 respective side are hinged, opposite side is bolted, on semicircle centre frame base 1 and semicircle centre frame gland 3, be distributed with three and be the back shaft 4 of 120 °, in back shaft 4, guiding is combined with operating axis 5, the outer end of operating axis 5 is provided with action bars fixed cover 6 and handles bowl cover 7, the other end of operating axis 5 is provided with supporting member 8.On described semicircle centre frame base 1, be equipped with two and be the back shaft 4 of 120 °.
