Description

Silver-point riveting machine
Technical field:
The present invention relates to a kind of riveting machine, particularly a kind of riveting machine that is specifically designed to the riveted joint particular product.
Background technology:
In electric elements, the contact is common structural member, its design feature is that silver point is assemblied in the pre-manufactured hole of electrical equipment contact chip (as copper conducting strip), with riveted way silver point is fixed on the contact chip again, and the characteristics of this class product are that the scope of application is extremely wide, the quantity of product is very big, and silver point is small-sized, for a long time, and the assembling work between silver point and the electrical equipment contact chip, all be to finish in conjunction with a large amount of hand labours with operating mechanism, that generally adopts has following two kinds of fit:
Adopt existing press and be aided with the mould feeding, material loading and blanking are finished by manual operation, wherein in the operating process on silver point and the contact chip location centering of aperture be a big difficult point, though there is mould to lead, but still rely on manual just assisting, and silver point is small-sized, brings very big difficulty to the operator, and required operating time of obviously each riveted process is longer, not only production efficiency is extremely low, and labour intensity is also bigger, and the running cost of product also rises thereupon, simultaneously, in the press operation process, staff very easily causes personal injury at any time with corresponding action, and is very dangerous;
Adopt the fit of precision index plate press, because the use of precision index plate, centering location condition between silver point and the contact chip aperture improves, but the material loading of precision index plate operation and the riveted stroke of press be respectively by the cooperation of artificial its operation of realization be connected, obviously, the coordination of precision index plate and press is to rely on operator's technical ability to guarantee synchronously, as obtaining than the operation of fast pace and the goods of better quality, must finish by operator than high-tech, its corresponding processing cost rises thereupon, as finishing by general operation person, it is out of control easily that human factor cooperates work, and simultaneously, corresponding labour intensity is still bigger, therefore the production efficiency raising is not obvious, and production cost is still higher.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of improved silver-point riveting machine, and it can improve the production efficiency of silver point and contact chip riveted joint greatly, can guarantee that goods have good quality simultaneously, and can obviously reduce operator's labour intensity.
The technical scheme that the present invention solves the problems of the technologies described above employing is, silver-point riveting machine includes framework, pressure head component, silver point lowering mechanism and vibrating bunker, framework is provided with the each several part assembly of riveting machine, silver point lowering mechanism and vibrating bunker butt joint, be characterized in: the silver-point riveting machine structure is provided with electronic cam rocker arm mechanism, the cam that sets firmly on the camshaft of cam rocker arm mechanism holds an end of rocking arm, the shaft extension end of camshaft is connected with stable drive ratio mechanism, stable drive ratio mechanism is connected with indexing mechanism, the index dial of indexing mechanism is to there being the guide rail of silver point lowering mechanism, and the other end of the rocking arm of cam rocker arm mechanism drives and is connected with pressure head component.The vibrating bunker feeding silver point of silver-point riveting machine is to the silver point lowering mechanism, and make its gravity of silver point mat fall into the silver point anchor point of index dial in regular turn exactly along the tilting track of this mechanism, along with electronic camshaft rotation, whenever circle, cam holds an once also riveting action of drive ram do of rocking arm swing, and being Mechanical Driven, camshaft and stable drive ratio mechanism and calibration machinery is connected, it is mechanical synchronization that the index dial rotation of indexing mechanism and rocking arm band pressure head move, promptly at anchor point of index dial revolution, rocking arm drives pressure head and does a riveted action.
The present invention adopts the technical scheme of feeding index dial and pressure head mechanical linkage, accurately deliver to silver point under the pressure head with precision index plate, pressure head can accurately press-fit, and be aided with the silver point lowering mechanism accurate limit, put the site that presets that design, silver point can automatically enter index dial, fundamentally overcome the defective of legacy equipment, can not only boost productivity greatly, can guarantee the quality of product simultaneously, and can also reduce operator's labour intensity significantly.
