Description
Technical field
The utility model relates to a kind of riveting gathering apparatus, especially relates to a kind of ultrasonic wave riveting gathering apparatus.
Background technology
Usually the riveting heading of rivet machine all has bigger quality, and it just has bigger inertia like this.Under the effect of external force, the riveting heading with a bigger speed to being impacted by the workpiece of riveting, in moment the kinetic energy that self had is converted into impact energy, impel workpiece at the big energy of local absorption that is impacted, produce deformation, other position is then unaffected substantially, thereby reaches the purpose that riveting is upset.Standard machinery formula riveting gathering apparatus is owing to the restriction of mechanical type force mechanism, and application of force frequency is lower, and impact speed and impulsive force are also less, has limited impulsive force and frequency of impact that riveting is upset.
Summary of the invention
Goal of the invention of the present utility model provides the riveting that a kind of impulsive force is big, frequency of impact is high gathering apparatus at not enough more than the standard machinery formula riveting gathering apparatus.
Goal of the invention of the present utility model is mainly solved by following technical proposals: a kind of ultrasonic wave rivet machine, the ultrasonic wave driving power is connected by power line with the ultrasonic transducer that is provided with in the enclosure, the amplitude output end of ultrasonic transducer is connected with the luffing bar, the place, periphery of luffing bar is provided with boss, and boss is fixed on the shell of rivet machine; One end mounting ultrasonic transducer of luffing bar, the other end of luffing bar is connected with tool heads; Riveting rammer end perforate on shell of rivet machine is provided with the riveting heading, and the riveting heading places the end face of tool heads, but does not link to each other.
Goal of the invention of the present utility model can also further be able to perfect by following technical proposals: described shell is divided into front casing and rear casing two parts, and front casing is connected with connector with the spacer flanger dish respectively with rear casing; The boss of luffing bar be ring-type or or form by some lugs, be embedded in the middle of the groove of fixed flange, fixed flange is embedded in the middle of the groove that front casing and spacer flanger dish form; The riveting heading comprises the cylinder of cap body and front end, and the front end of riveting heading cylinder can be provided with one or more impact bodies, is surface blending between impact body and the cylinder; The end face of described impact body is the plane, also can make cambered surface as required.
The thrust that excites the motion of riveting heading of ultrasonic wave rivet machine derives from the ultrasonic transducer that is made of piezoelectric ceramics, and its operation principle is: the ultrasonic wave driving power converts civil power to the high-frequency high-voltage alternating current, is defeated by ultrasonic transducer.The ultrasonic transducer reversed piezoelcetric effect of utilizing piezoelectric ceramics converts the electric energy of input to mechanical energy then, i.e. ultrasonic wave, and it takes the form of transducer and is vertically making reciprocal stretching motion; The frequency of stretching motion is equal to the AC current frequency of driving power, and flexible displacement is about tens microns.The effect one of luffing bar is fixing whole ultrasonic ripple vibrational system, and making vibrational system is that the center moves reciprocatingly with the lug boss position; The 2nd, the output amplitude of transducer is amplified.Tool heads (force application apparatus) is amplified to amplitude on the one hand and reaches more than 100 microns, on the other hand the riveting heading is applied impulsive force, promotes to impact head and makes high-speed motion.After the riveting heading impacted workpiece, speed was decreased to 0 meter per second by being not less than 1.5 meter per seconds in a short period of time, and most of energy has little time to the workpiece internal delivery, made the workpiece position local deformation that is hit.The riveting heading is subjected to resilience after the reaction of workpiece, run into the tool heads of dither after, excited once more, hit again workpiece at a high speed, so repeated multiple times is finished riveting rammer operation.
As preferably, the end face of riveting heading impact body is selected hard material for use, can be selected from a kind of in high-speed steel, steel alloy, tool steel or the carbide alloy, can be the above-mentioned hard material of the whole employing of riveting heading, also can be that the end face of riveting heading impact body adopts mosaic texture or sintering process partly to adopt above-mentioned hard material.In order to reduce the wearing and tearing of riveting heading cap body or tool heads, tool heads and riveting heading cap body can be selected commaterial for use, or adopt with a kind of above-mentioned hard material.The weight of riveting heading 1 restrain 300 the gram between, preferred weight be 10 restrain 300 the gram between.The weight of riveting heading is big more, and inertia is also big more, and frequency of impact is low more.Gap between riveting heading and the tool heads is 0.20～3.0 millimeter.The little then impulsive force in gap reduces, and frequency of impact is accelerated; The gap is big, and then impulsive force is big, and frequency of impact reduces.The weight of riveting heading is little, then the little frequency of impact height of inertia.
As preferably, the end face that has at least in riveting heading cap body end face or the tool heads riveting rammer end face is provided with some grooves or projection, or the formed latticed groove of groove or the point-like projection of intersecting more than two.The area of riveting heading cap body end face and tool heads riveting rammer end face near the time, contact-making surface at tool heads or riveting heading is provided with groove or projection, can reduce both effective contacts area, makes tool heads and riveting heading as two separate components, has different motion frequencies, to finish riveting rammer action.
As preferably, luffing bar and tool heads are column structure, and have at least one to adopt diameter contraction type structure, so that rationally amplify amplitude, make impact energy concentrate on shock point.
As preferably, rivet machine is fixed on the pedestal, and the rivet machine pedestal places on the support.
In addition, the shell input is provided with cooling fan, is provided with ventilating opening on the rear casing outer wall, handles thereby the ultrasonic wave riveting rammer system in the shell is carried out air cooling.
Generally more than 10kHz, the application of force frequency of impacting the exciting force of head also reaches more than the 10kHz frequency of high-power ultrasonics vibrational system, and that general the most frequently used is 15～20kHz.The acceleration of motion of ultrasonic wave force part can reach 3 * 10 simultaneously
4Meter per second
2More than, according to mechanics formula F=ma as can be known, the force part liquidates to tap the head and applies very big motive force.Therefore the ultrasonic wave rivet machine has very big advantage in the die operation of miniature workpiece, can finish the die operation fast like a cork.
