Description
Technical Field
The utility model relates to a live center, concretely relates to live center for turning slender axles belongs to the machining field.
Background
The processing of the slender shaft part is a technical problem of turning processing because the slender shaft part is easy to bend and deform and the size consistency is difficult to guarantee, and the effect after the slender shaft is turned is not ideal because a clamping mode that one end of a chuck is used for clamping and the other end of the chuck is used for jacking is generally adopted during processing.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the processing of slender axles parts, because easy bending deformation, size uniformity are difficult to the problem of guaranteeing, and then provide a turning is elastic top for slender axles.
The utility model discloses a solve the technical scheme that above-mentioned problem was taken and be: the utility model discloses a top, the utility model discloses still include the elastic buffering subassembly and the top body, the front end at the top body is installed to the elastic buffering subassembly, top installation on the elastic buffering subassembly.
Furthermore, the centre body comprises taper shank and installation casing, and the bottom surface of installation casing and the front end fixed connection of taper shank become an organic whole, elastic buffer unit installs in the installation casing.
Further, the taper shank is a taper body with an outer contour gradually reduced from front to back, and the taper of the taper body is 5 degrees in a Moire mode.
Furthermore, the elastic buffering assembly comprises a spring, a bearing group and a gland, the bearing group and the spring are sequentially arranged in the mounting shell from front to back, the gland is buckled at a notch of the mounting shell, and the rear end of the tip penetrates through the gland and is inserted into the bearing group.
Furthermore, the bearing group is formed by sequentially overlapping three ball bearings.
Further, the spring is a belleville spring.
Further, the length of the apex body is 225 mm.
The utility model has the advantages that: the utility model discloses have double-phase belleville spring to setting up, but minute axial elastic displacement, when producing the thermal energy and making the part take place to warp in the part course of working, can freely reduce the bending deformation of part to endwise slip.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
The first embodiment is as follows: the present embodiment is described with reference to fig. 1, and the present embodiment describes a resilient center for turning an elongated shaft, which includes a center 1, a resilient buffer assembly and a center body 2, wherein the resilient buffer assembly is mounted at the front end of the center body 2, and the center 1 is mounted on the resilient buffer assembly.
When the slender shaft is turned and the workpiece is thermally expanded, the center 1 can axially and elastically displace, so that the axial supporting force is reduced, and the bending deformation in the machining process is reduced.
The second embodiment is as follows: the tip body 2 of the elastic tip for turning the slender shaft is composed of a taper shank 2-1 and a mounting shell 2-2, the bottom surface of the mounting shell 2-2 is fixedly connected with the front end of the taper shank 2-1 into a whole, and the elastic buffer assembly is mounted in the mounting shell 2-2. Other components and connections are the same as those in the first embodiment.
The third concrete implementation mode: the taper shank 2-1 of the spring center for turning the slender shaft is a taper body with the outer contour gradually tapered from front to back, and the taper of the taper body is 5 degrees. Other components and connection relationships are the same as those in the second embodiment.
The fourth concrete implementation mode: the embodiment is described with reference to fig. 1, and the elastic buffer assembly of the elastic center for turning the slender shaft in the embodiment comprises a spring 3, a bearing group 4 and a gland 5, wherein the bearing group 4 and the spring 3 are sequentially arranged in an installation shell 2-2 from front to back, the gland 5 is buckled at a notch of the installation shell 2-2, and the rear end of the center 1 penetrates through the gland 5 and is inserted into the bearing group 4. Other components and connection relationships are the same as those in the first or second embodiment.
The fifth concrete implementation mode: the present embodiment is described with reference to fig. 1, and the bearing set 4 of the spring center for turning the slender shaft according to the present embodiment is formed by sequentially stacking three ball bearings. Other components and connection relationships are the same as those in the fourth embodiment.
The sixth specific implementation mode: the present embodiment will be described with reference to fig. 1, and the spring 3 of the elastic center for turning an elongated shaft according to the present embodiment is a belleville spring. Other components and connection relationships are the same as those in the fourth embodiment.
Seventh embodiment referring to fig. 1, the tip body 1 of the spring tip for turning slender shafts according to the present embodiment has a length L of 225 mm.
Principle of operation
When the center 1 works, when the part is deformed due to thermal expansion generated in the processing process of the part, the center can freely slide axially, and the bending deformation of the part is reduced.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed with the preferred embodiment, it is not limited to the present invention, and any skilled person in the art can make modifications or changes equivalent to the equivalent embodiment without departing from the technical scope of the present invention, but all the modifications, equivalent substitutions, and improvements made to the above embodiments within the spirit and principle of the present invention still belong to the protection scope of the technical solution of the present invention.
