Description
Technical field
The present invention relates to a kind of transmission device of clincher tool.
Background technology
New riveting technology is promoted, and being widely used of riveting nut had new demand to its supporting instrument.It is simple light and handy that instrument is wanted, and use is convenient and strength-saving, and all is the operation principle that adopts the link supports formula with traditional riveting nut hand-operated tools in the market, through the active force of handle, makes the connecting plate that is connected on the handle drive sliding core and moves backward, reach riveted joint.This kind is configured in the transmittance process of power, and the amplification coefficient of power is sinusoidal variation, and the operator requires great effort very much, because big specification riveting nut uses; For the laborsaving long handle arm of force that adds, original enough heavy instruments are increased the weight of again, simultaneously the parts well damage; The user can't long time continuous working, has influenced the riveted joint working (machining) efficiency, especially when the above riveting nut of needs riveted joint M10; Can't buy the supporting hand-operated tools of ability on the market, the conventional tool processed complex makes trouble in addition.
In view of the foregoing, be necessary a kind of light and handy push mode riveted joint transmission device that uses newly developed.
Summary of the invention
Technical problem to be solved by this invention is, uses effort, and easy impaired problem to existing transmission device, and a kind of simple in structure, push mode riveted joint transmission device that operation is light and handy is provided.
In order to solve the problems of the technologies described above, the present invention adopts following technical proposal:
A kind of push mode riveted joint transmission device comprises a pull bar, rifle head, tool body and main plunger tip, and back end of tie rod is provided with knob; The tool body both sides respectively flexibly connect core shift wheel, and each core shift wheel connects one handle respectively, and main plunger tip rear end is provided with curved surface; The core shift wheel contacts with the curved surface of main plunger tip rear end, the solid press spring base of outside, main plunger tip rear portion cover, and press spring base rear end and tool body front end are fixed; One back-moving spring is sleeved on outside the main plunger tip; Main plunger tip rear end and press spring base rear end all are provided with step, and the front end of back-moving spring connects the step of press spring base rear end, and the rear end of back-moving spring connects the step of main plunger tip rear end; Rifle back of head suit is become owner of the front, inside of plunger tip and is threaded, and pull bar passes tool body, main plunger tip and rifle head from back to front successively.
Described rifle head front end is protruding, and between the convexity of main plunger tip front end and rifle head suit one locking nut.
The outside suit one of described main plunger tip is regulated the adjusting nut of main plunger tip stroke, and adjusting nut is connected with main plunger tip external screw-thread.
Described tool body rear end is provided with cavity, and the cavity inwall is provided with the knob base corresponding with knob.
The technique effect of the utility model is in particular in: change traditional form, simplified structure is exempted connecting rod slider mechanism, is organically combined the core shift transmission device; Let originally active pull rod is fixed on the sliding in-core hole site, make sliding core forward pushing tow reach the riveted joint effect, remove a part of jockey like this from; Simultaneously with high-strength nylon through repeatedly the experiment, the successful substituted metal material body of a gun makes instrument lightly laborsaving; Simple in structure, be the ideal riveted joint hand-operated tools of current a new generation.
Described tool body is whole the central point of instrument, and handle core shift wheel in the left and right sides contacts with main plunger tip bottom circular arc camber shape, and formation is in transmission connection; Pass main plunger tip endoporus to pull bar; The screw thread that centre-lock, head expose can be adorned all size riveting nut identical with pull rod screw, when left and right sides handle closes up; The core shift of contact position is apart from becoming big gradually on core shift wheel top and the main plunger tip bottom arc surface; To the upper end pushing tow, and the main plunger tip upper end riveting nut shade on the rifle head being housed and being contained in pull bar contacts main plunger tip, and both hands then pass to riveting nut through core shift wheel, main plunger tip, rifle head to the active force amplification of left and right sides handle like this; Make riveting nut pipe shaft generation curve deformation, reach the riveted joint effect.When the core shift wheel reset to starting point again, the promptly outside main plunger tip of promotion of upholding of back-moving spring that is contained on the main plunger tip resetted.
Owing to changed the stressed direction of motion, make the core shift wheel become 21 °-23.5 ° angle with the center line movement direction of main plunger tip with the normal of main plunger tip contact point, its initial angle is very little with the termination variable angle; The active force variation is also very little for this reason, and is more laborsaving more than 30% than conventional tool, and new type of belt drive has saved step connection; The first-class change of material makes instrument weight saving half the; Simultaneously, simplify the processing technology of enterprise, reduced production cost.Because the hand-operated tools price is low, the convenient use, purposes is wide.
