Abstract
The utility model relates to a fixture for elongated shaft turning. The fixture comprises a three-jaw chuck and a machine tool centre, a bead ring is arranged in the three-jaw chuck, the machine tool center comprises a centre head, a centre body and an elastic part, the centre head is arranged in the centre body, and the elastic part is arranged between the centre head and the centre body. By the aid of the fixture for elongated shaft turning, an elongated shaft to be machined is less susceptible to cutting force to generate bending deformation during turning, surface roughness and geometric accuracy of the elongated shaft to be machined can meet requirements, and machining quality is improved greatly.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind ofly on lathe slender axles is carried out turning and adds the anchor clamps of using man-hour, belongs to the Workpiece clamping device technical field of machining.
Background technology
The diameter of slender axles and length ratio are generally all greater than 20.It carries out turning and adds man-hour on lathe, if with the processing mode of the direct clamping of scroll chuck, in process, the periphery of slender axles is subjected to the impact of cutting force to produce flexural deformation easily; Because the slender axles heat diffusivity is poor, heat in metal cutting causes the surface roughness of slender axles and geometric accuracy not to reach requirement so that slender axles produce the line expansion, has affected crudy again.
The utility model content
The utility model purpose is that the impact that provides a kind of slender axles not to be subject to cutting force in order to overcome the deficiencies in the prior art in process produces flexural deformation and the good Turning of Slender Shaft fixture for processing of crudy.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Turning of Slender Shaft fixture for processing, comprise that scroll chuck and lathe are top, and comprise in the described scroll chuck being provided with wire loop; Top centre head, top body and the elastomeric element of comprising of described lathe; Described centre head is arranged in the top body; Be provided with elastomeric element between described centre head and top body.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Turning of Slender Shaft fixture for processing of the present utility model during use, inserts slender axles to be processed in the wire loop, then with the top head that withstands slender axles to be processed of lathe, realizes clamping.Because wire loop exists, for line contacts, and wire loop can play the effect of universal adjustment between scroll chuck and the slender axles to be processed, so that slender axles to be processed are not subject to the impact generation flexural deformation of cutting force in process; Again because top centre head, top body and the elastomeric element of comprising of lathe, centre head is arranged in the top body, be provided with elastomeric element between centre head and top body, slender axles to be processed can axial stretching, the line that the compensation heat in metal cutting causes expands, so that the surface roughness of slender axles to be processed and geometric accuracy can reach requirement, greatly improved crudy.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of Turning of Slender Shaft fixture for processing of the present utility model;
Accompanying drawing 2 is the use status architecture schematic diagram of Turning of Slender Shaft fixture for processing of the present utility model;
Wherein: 1, scroll chuck; 2, wire loop; 3, centre head; 4, top body 5, elastomeric element; 6, slender axles.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of Turning of Slender Shaft fixture for processing as shown in Figure 1 comprises that scroll chuck 1 and lathe are top, comprises in the described scroll chuck 1 being provided with wire loop 2; Top centre head 3, top body 4 and the elastomeric element 5 of comprising of described lathe; Described centre head 3 is arranged in the top body 4; 4 of described centre head 3 and top bodies are provided with elastomeric element 5.
Described in the utility model a kind of Turning of Slender Shaft fixture for processing as shown in Figure 2 during use, during use, inserts slender axles to be processed 6 in the wire loop 2, then with the top head that withstands slender axles to be processed 6 of lathe, realizes clamping.
Turning of Slender Shaft fixture for processing of the present utility model, because wire loop 2 exists, contact for line between scroll chuck 1 and the slender axles 6 to be processed, and wire loop 2 can play the effect of universal adjustment, does not produce flexural deformation so that slender axles 6 to be processed are not subject to the impact of cutting force in process; Again because centre head 3 and 4 of top bodies are provided with elastomeric element 5, slender axles 6 to be processed can axial stretching, the line that the compensation heat in metal cutting causes expands, so that the surface roughness of slender axles 6 to be processed and geometric accuracy can reach requirement, has greatly improved crudy.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
