Description

A kind of clincher tool of from inside to outside riveting workpiece

Technical field

The utility model belongs to frock and riveting technology field, relate to a kind of clincher tool of from inside to outside riveting workpiece, be specially adapted to from inside to outside rivet workpiece, be particularly useful for the riveted joint processing that the split type hydraulic power steering device geometrical clamp of housing oil cylinder is connected with oil cylinder.

Background technology

Mostly existing riveting technology is to rivet from outside to inside workpiece, and the workpiece appearance has the riveted joint impression.

For the split type hydraulic power steering gear of housing oil cylinder, all be to be connected and fixing between oil cylinder one side and the vehicle subframe by geometrical clamp.Connected mode between existing geometrical clamp and the steering gear oil cylinder mainly contains two kinds: a kind of is the steel geometrical clamp, and embedded rubber bushing between the oil cylinder, geometrical clamp directly is connected with bolt with subframe, and this mode is simple, can guarantee that elasticity connects, but have insufficient rigidity, fixing unstable problem; A kind of is that steel geometrical clamp and oil cylinder directly weld together, and this mode coupling stiffness is guaranteed, but welding is easy to generate distortion, influence the oil cylinder internal diameter, and weld seam is wayward.Product design adopts oil cylinder one end to be pressed into the geometrical clamp axial bore, oil cylinder and geometrical clamp from inside to outside are riveted together by four riveting points, rigidity is guaranteed, connect firm, do not have welding distortion, the wayward problem of weld seam, do not have the riveted joint impression, but need a clincher tool of riveted joint from inside to outside.

Summary of the invention

The utility model discloses a kind of clincher tool of riveted joint from inside to outside, is connected with bolt between the geometrical clamp that solves the split type hydraulic power steering gear of prior art middle shell oil cylinder and the steering gear oil cylinder, insufficient rigidity, fixes shakiness; Be welded to connect and produce distortion, weld seam is wayward, adopt and from inside to outside rivet product design, the outside problems such as clincher tool of riveted joint in having no way of.

The utility model comprises die; It is characterized in that: also comprise riveting piece, riveting cover; The riveting piece has T type groove slide rail and a spigot surface, and T type groove slide rail and riveting piece center line have greater than 0 ° of angle less than 45 °; The riveting piece is installed in the riveting cover, and the spigot surface of riveting piece and riveting cover are slidingly matched; The riveting piece is connected with the lifting shaft of equipment, moves up and down with the lifting shaft of equipment; Die has protruding guide pad, and the protruding guide pad of die is installed in the riveting piece T type groove slide rail; The riveting cover has bore of the punch, and the drift of die is installed in the bore of the punch of riveting cover; The bore of the punch matched in clearance of the drift of die and riveting cover; The bottom-up slip of T type groove slide rail that die tilts along the riveting piece, the T type groove slide rail promotion die that the riveting piece tilts stretches out from inside to outside along the bore of the punch of riveting cover.

The bore of the punch quantity of riveting cover equals die quantity, and equals the T type groove slide rail quantity of riveting piece.

Preferred T type groove slide rail and riveting piece center line angle are 5 °--15 °.

The riveting cover also has spacing preiection, and it is spacing to be used for workpiece riveting point.

The utility model advantage is: can realize product riveted joint from inside to outside, instrument is easy to use, reliable operation.Be particularly useful for the riveted joint processing that the split type hydraulic power steering device geometrical clamp of housing oil cylinder is connected with oil cylinder.
