Abstract
The utility model provides an aircraft nose is radially riveted to plum blossom form, includes riveter fixed block, concave spherical surface piece, convex spherical piece, riveting axle and meshed gear, the concave spherical surface piece passes through the fix with screw at riveter fixed block top, the nested top of going into the concave spherical surface piece of meshed gear, meshed gear divide into external toothing pinion and inner gearing gear wheel, external toothing pinion bottom is connected with the eccentric shaft, the convex spherical piece is located the arc surface below of the inside concave spherical surface piece of riveter fixed block, upper portion is equipped with the riveting ball in the convex spherical piece, the riveting axle passes through the riveting ball and pushes up on the arc surface of concave spherical surface piece riveting axle and eccentric shaft connection. The utility model discloses at riveting in -process sliding motion on concave, convex spherical piece, make the riveting axle drive the riveting drift and accomplish the radial rolled motion of a similar plum blossom form, change riveting power into the face contact by the point contact, only need just to enable to rivet the quality and obtain the improvement on a very little effort is used in the rivet.
Description
Technical field
The utility model relates to a kind of riveting machine, particularly relates to a kind of with the head of plum blossom-shaped radial motion riveting machine.
Background technology
In machining, riveting machine is the machine be in daily use, and especially in massive mechanical processing, the working strength of riveting machine and frequency are higher.Now widely used riveting technology is with swing type circular motion riveting, and in riveting process, rivet distortion is mainly tangentially, and vertical direction active force is large and radial forces is less, and the workpiece deformation that riveted joint is gone out is comparatively large, and surface roughness is poor, and riveting quality is not high.
Summary of the invention
The utility model, for solving the problem, provides a kind of plum blossom-shaped radial rivet head, to improve linking intensity and the surface quality of riveting parts.
Technical solution adopted in the utility model:
A kind of plum blossom-shaped radial rivet head, comprise riveting machine fixed block, concave spherical surface block, convex spherical block, riveting axle and meshing gear, described concave spherical surface block is fixed by screws in riveting machine fixed block top, described meshing gear is nested into the top of concave spherical surface block, meshing gear is divided into external toothing pinion and internal messing gear wheel, external toothing pinion bottom is connected with eccentric shaft, convex spherical block is positioned at below the arc surface of the inner concave spherical surface block of riveting machine fixed block, convex spherical block internal upper part is provided with riveting abrading-ball, riveting axle withstands on the arc surface of concave spherical surface block by riveting abrading-ball, riveting axle is connected with eccentric shaft.
Described convex spherical block both sides are provided with the spring that convex spherical block can be made to be close to concave spherical surface block.
The riveting drift of described riveting axle bottom connection enlarging type.
The beneficial effects of the utility model: the utility model in riveting process on concave, convex sphere block sliding motion, riveting axle is made to drive riveting drift to complete a radial rolling motion of similar plum blossom-shaped, rivet force is changed into face by point cantact contact, the active force that only needs one are very little acts on rivet, and riveting quality just can be made to be improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-eccentric shaft; 2-concave spherical surface block; 3-riveting machine fixed block; 4-convex spherical block; 5-riveting drift; 6-riveting axle; 7-spring; 8-screw; 9-riveting abrading-ball; 10-external toothing pinion; 11-internal messing gear wheel.
Detailed description of the invention
A kind of plum blossom-shaped radial rivet head, comprise riveting machine fixed block 3, concave spherical surface block 2, convex spherical block 4, riveting axle 6 and meshing gear, described concave spherical surface block 2 is fixed on riveting machine fixed block 3 top by screw 8, described meshing gear is nested into the top of concave spherical surface block 2, meshing gear is divided into external toothing pinion 10 and internal messing gear wheel 11, external toothing pinion 10 bottom is connected with eccentric shaft 1, convex spherical block 4 is positioned at below the arc surface of the inner concave spherical surface block 2 of riveting machine fixed block 3, convex spherical block 4 internal upper part is provided with riveting abrading-ball 9, riveting axle 6 withstands on the arc surface of concave spherical surface block 2 by riveting abrading-ball 9, riveting axle 6 is connected with eccentric shaft 1.
Described convex spherical block 4 both sides are provided with the spring 7 that convex spherical block 4 can be made to be close to concave spherical surface block 2.
The riveting drift 5 of described riveting axle 6 bottom connection enlarging type.
During riveted joint, the axial force that cylinder or oil pressure produce promotes concave spherical surface block 2 by piston and acts on convex spherical block 4, then is delivered on riveting axle 6, thus acts on riveted joint workpiece.
