Description
Technical Field

Background
As the most promising cold-working surface strengthening treatment process for metal materials at present, ultrasonic strengthening is widely used in the mechanical manufacturing process, and for example, ultrasonic strengthening can be used for surface forming of parts such as aircraft panel parts and carrier rocket tanks, and for straightening of deformed members by mechanical processing such as casting, welding, and pressing.
The ultrasonic strengthening process mainly utilizes a shot piece or a firing pin and other jet pieces to impact the surface of the structural part at a high speed under the action of ultrasonic waves, so that a strengthening layer is generated on the surface of the structural part, and the fatigue life, the stress corrosion resistance and the like of the structural part are improved.
The ultrasonic strengthening equipment in the prior art is started again after the spraying piece impacts a workpiece mainly by means of the gravity of the spraying piece or negative pressure suction, so that the spraying piece continuously collides with an amplitude transformer of ultrasonic vibration, the spraying piece is continuously excited to be sprayed out, and the surface of the workpiece is strengthened.
However, when the spray member is activated by its own weight, the workpiece must be suspended and the ultrasonic reinforcement device is located right under the workpiece, so that the processing direction of the workpiece is limited and the workpiece needs to be continuously turned over so that different surfaces of the workpiece face the ultrasonic reinforcement device.
When the spraying piece is started by means of negative pressure suction, on one hand, due to the action of the negative pressure suction, impurities such as metal chips or dust are easily sucked into the ultrasonic strengthening equipment, so that the electrical equipment is in a disconnection risk, equipment faults are caused, or the smoothness of the movement of the spraying piece is influenced, and the manufacturability of the surface treatment of the workpiece is influenced. On the other hand, since the maximum pressure of the negative pressure is one atmosphere, there is an upper limit to the suction pressure, and therefore, this method is only applicable to a very small number or light weight of ejection members, for example, a single-point or line strengthening treatment such as stress relief of a weld or the like is performed using a single firing pin or a very small number of firing pins. For the ejection member with a large size and a heavy gravity, the ejection member cannot be absorbed to the surface of the ultrasonic vibration horn under the negative pressure condition in general so that the ejection member is ejected, or the impact force of the ejection member is small, so that the strength of the surface of the workpiece after the strengthening treatment is low.
In summary, those skilled in the art need to solve the above-mentioned problems, how to provide an ultrasonic strengthening and shape-correcting device that can realize a surface strengthening and shape-correcting process of a workpiece in different directions, prevent impurities such as metal chips from entering the inside of the device, and is suitable for a heavy and large-sized injection member.

The invention provides an ultrasonic strengthening orthopedic device which mainly comprises an ultrasonic power supply 11, an ultrasonic transducer 12, a vibrating body 13, a jet body 2, an end cover 3, a positive pressure air source 4 and the like.
Specifically, the ultrasonic transducer 12 is connected to the ultrasonic power source 11, the vibration body 13 is provided at an output end of the ultrasonic transducer 12, the ultrasonic power source 11 is configured to input a high-frequency current into the ultrasonic transducer 12, the ultrasonic transducer 12 is configured to convert an electric power input by the ultrasonic power source 11 into a mechanical power of longitudinal wave vibration and transmit the longitudinal wave vibration to the vibration body 13, and the vibration body 13 is configured to impact the ejection body 2 so that the ejection body 2 is ejected.
The jet body 2 is used for continuously impacting the surface of the workpiece under the action of the vibrating body 13 so as to realize an ultrasonic strengthening process on the surface of the workpiece.
The end cover 3 is used for arranging the injection body 2, and the end cover 3 is provided with an injection hole and an air flow passage 31, wherein the injection hole is used for being matched with the injection body 2 in a sliding mode, so that the injection body 2 can move relative to the injection hole under the action of force.
The air flow passage 31 is communicated with the injection hole, and the inlet of the air flow passage 31 is connected with the positive pressure air source 4, so that the air flow passage 31 is filled with positive pressure air by the positive pressure air source 4.
The jet body 2 is provided with a pressure bearing surface 21 for receiving the pressure of the gas at positive pressure, and it will be appreciated that the gas flow passages 31 are aligned with the pressure bearing surface 21 to enable the gas at positive pressure to act on the pressure bearing surface 21 to cause the gas at positive pressure to urge the jet body 2 against the vibration body 13 to effect actuation of the jet body 2.
That is to say, in the working process, the positive pressure gas pushes the ejection body 2, so that the ejection body 2 collides against the vibration body 13, the vibration body 13 vibrates at high frequency under the action of the ultrasonic transducer 12, and at the moment that the ejection body 2 collides against the vibration body 13, the ejection body 2 is ejected onto a workpiece, so that the ejection body 2 impacts the surface of the workpiece, the ejection body 2 rebounds after impacting and colliding with the surface of the workpiece, at this time, the ejection body 2 collides against the vibration body 13 again under the positive pressure of the positive pressure gas, and the operation is repeated in such a reciprocating way, so that the ejection body 2 continuously impacts the surface of the workpiece, and the purpose of performing ultrasonic strengthening and shape correction on the surface of the.
Therefore, the invention starts the jet body 2 through the positive pressure of the positive pressure gas, leads the jet body 2 to collide with the vibration body 13, converts the ultrasonic energy into the high-speed impact of the jet body 2 on the surface of the workpiece through the vibration body 13, and leads the surface of the workpiece to generate plastic deformation, thereby realizing the strengthening or reshaping process of the surface of the workpiece.

It should be noted that the pressure-bearing face 21 of the jet body 2 is always within the alignment range of the gas flow passage 31 during the entire stroke of the jet body 2, so that the positive pressure gas can always act on the pressure-bearing face 21, and the situation that the positive pressure gas cannot activate the jet body 2 is avoided.
In consideration of the force applied to the pressure receiving face 21, the air flow path 31 is provided perpendicular to the axis of the injection hole on the basis of the above-described embodiment, and the pressure receiving face 21 is an inclined face inclined with respect to the moving direction of the jet body 2.
That is, the positive pressure gas directly acts on the inclined surface of the ejection body 2 in a direction perpendicular to the moving direction of the ejection body 2, and generates pressure on the inclined surface, causing the ejection body 2 to collide against the vibration body 13 to activate the ejection body 2.
In consideration of the specific structure of the end cap 3 and the specific arrangement of the gas flow channel 31, on the basis of the above-mentioned embodiment, the end cap 3 includes a cap body 32 and a top cap 33 provided at one end of the cap body 32, the end of the cap body 32 facing the top cap 33 is provided with a sunken groove, the sunken groove and the inner end surface of the top cap 33 form the gas flow channel 31, the cap body 32 is provided with a connecting hole communicated with the sunken groove, and a gas pipe 41 connected with the positive pressure gas source 4 is hermetically connected with the connecting hole.
That is, in the present embodiment, the cover 32, the top cover 33 and the air pipe 41 form a closed high-pressure air chamber, that is, the air flow passage 31, and the positive pressure air is supplied from the positive pressure air source 4 to the sink via the air pipe 41 to activate the jet body 2.
The lid 32 and the top cover 33 may be fixed by welding, by bolts, or the like.
Preferably, the ultrasonic generator further comprises a shell 7, the cover 32 is fixedly connected with the shell 7, the ultrasonic transducer 12 and the vibrating body 13 are arranged in the shell 7, and the air pipe 41 is connected with the connecting hole through the inner space of the shell 7.
In order to make the pressure-bearing face 21 be acted on by the pressure of the positive pressure gas in the whole stroke of the injection body 2, on the basis of the above-mentioned embodiment, the top cover 33 is provided with a first injection hole penetrating through the thickness thereof, the cover body 32 is provided with a second injection hole penetrating through the thickness thereof, and the first injection hole and the second injection hole are arranged in one-to-one correspondence; the injector body 2 includes a first cylindrical portion 22 and a second cylindrical portion 23, the first cylindrical portion 22 being adapted to be slidably fitted with a first injection hole, the second cylindrical portion 23 being adapted to be slidably fitted with a second injection hole; the first cylindrical portion 22 and the second cylindrical portion 23 are transitionally connected by the pressure-bearing face 21, and the minimum radial dimension of the pressure-bearing face 21 is greater than or equal to the aperture of the first injection hole.
It will be appreciated that, since the pressure receiving face 21 is an inclined face, and as is known from the force applied to the inclined face, the radial dimension of the pressure receiving face 21 gradually decreases from the end thereof connected to the second cylindrical portion 23 to the end thereof connected to the first cylindrical portion 22, that is, the radial dimension of the second cylindrical portion 23 is larger than that of the first cylindrical portion 22.
Since the minimum radial dimension of the pressure-bearing face 21 is greater than or equal to the aperture of the first injection hole, that is, the pressure-bearing face 21 cannot pass through the first injection hole, when the portion of the pressure-bearing face 21 having the minimum radial dimension moves to the first injection hole, the pressure-bearing face 21 abuts against the end face of the first injection hole, and the injector 2 cannot continue to move in the direction close to the first injection hole, that is, at the position of the maximum stroke of the injector 2, at this time, the end of the injector 2 protruding from the first injection hole contacts with the surface of the workpiece, and impacts the surface of the workpiece.
Obviously, at this time, the positive pressure gas in the gas flow channel 31 may act on the entire inclined surface, and after the collision of the jet body 2 with the workpiece is completed, the jet body 2 collides against the vibration body 13 in the opposite direction by the positive pressure gas.

That is, the present embodiment mechanically restricts the stopper portion 25 by the partition 34, and prevents the injection body 2 from coming off from the second injection hole during the mounting process.
The lid 32 and the spacer 34 may be fixed by welding, by bolts, or the like.
It should be further noted that, in the above embodiments, the present invention does not limit the specific shape of the impact end 221 of the jetting body 2 for contacting with the workpiece surface, as shown in fig. 3 and 5, in order to adapt the jetting body 2 to workpiece surfaces with different shapes, on the basis of the above embodiments, the shape of the impact end 221 of the jetting body 2 for contacting with the workpiece surface is a plane, an arc, a sphere, a pointed angle, or the like, which can be selected by those skilled in the art according to actual needs.
On this basis, as shown in fig. 6, the impact end 221 of the jet body 2 is preferably provided with impact teeth 222, and the shape of the impact teeth 222 can be selected according to actual needs.
In addition, the specific material of the spray body 2 is not limited in the present invention, for example, the spray body 2 may be a metal spray body 2 or a ceramic spray body 2, so that the spray body 2 can meet the requirement of strengthening and orthopedic treatment of different material surfaces.
Further, in the above embodiments, the specific number of the injection bodies 2 is not limited, and can be selected by those skilled in the art according to actual needs.

In order to make the ejection body 2 have a larger stroke, on the basis of the above embodiments, the vibration body 13 is a variable amplitude vibration body 13 for amplifying the amplitude of the vibration output by the ultrasonic transducer 12, and the specific structure of the variable amplitude vibration body 13 can be referred to in the prior art, and is not limited in detail herein.
In consideration of the convenience of connecting the vibration body 13 and the ultrasonic transducer 12, it is preferable that the vibration body 13 and the ultrasonic transducer 12 are connected by a stud 14. Of course, the vibrating body 13 and the ultrasonic transducer 12 may be fixedly connected by other mechanical connection means such as welding.
Fig. 7 is a control block diagram of an ultrasound-enhanced orthopedic device according to an embodiment of the present invention.
In order to provide the jet body 2 with a proper impact strength, on the basis of any one of the above embodiments, the jet body 2 further comprises a controller 5 connected to the ultrasonic power supply 11 and the positive pressure gas supply 4, respectively, and the controller 5 is configured to control the output power of the ultrasonic power supply 11 and the gas flow rate of the positive pressure gas supply 4 so as to provide the jet body 2 with a preset impact strength by adjusting the output power of the ultrasonic power supply 11 and the gas flow rate of the positive pressure gas supply 4.
It can be understood that the impact strength of the jet body 2 is related to the positive pressure applied thereto by the positive pressure gas and the vibration energy of the vibration body 13, therefore, the present embodiment controls the output power of the ultrasonic power source 11 and the gas flow of the positive pressure gas source 4 respectively by the controller 5 to make the positive pressure generated by the positive pressure gas on the jet body 2 and the vibration energy of the vibration body 13 act together to make the jet body 2 have the appropriate impact strength.
The preset impact strength is the impact strength of the jet body 2 set by a person skilled in the art according to actual needs, and the specific magnitude of the preset impact strength is not limited in the present invention.
Preferably, the positive pressure gas source device further comprises a gas flow control unit 42 respectively connected to the positive pressure gas source 4 and the controller 5, and the controller 5 controls the gas flow of the positive pressure gas source 4 through the gas flow control unit 42, so as to control the magnitude of the positive pressure acting on the jet body 2.
It should be noted that the present invention does not limit the specific control method of the controller 5, for example, when the impact strength of the jet body 2 does not reach the preset impact strength and the output power of the ultrasonic power supply 11 does not reach the maximum output power, the output power of the ultrasonic power supply 11 is continuously increased until the output power of the ultrasonic power supply 11 reaches the maximum output power thereof, that is, the output power of the ultrasonic power supply 11 is increased to increase the impact strength of the jet body 2.
When the output power of the ultrasonic power supply 11 reaches the maximum output power thereof and the impact strength of the ejection body 2 does not reach the preset impact strength yet, the controller 5 controls the air flow of the positive pressure air source 4 to be continuously increased until the air flow of the positive pressure air source 4 reaches the maximum air flow thereof, that is, at this time, when the output power of the ultrasonic power supply 11 reaches the maximum output power thereof, the impact strength of the ejection body 2 is increased by increasing the air flow of the positive pressure air source 4.
When the impact strength of the jet body 2 is greater than the preset impact strength and the output power of the ultrasonic power supply 11 is greater than the minimum output power thereof, the impact strength of the jet body 2 is reduced by controlling the output power of the ultrasonic power supply 11 to be continuously reduced by the controller 5 until the output power of the ultrasonic power supply 11 reaches the minimum output power thereof.
When the output power of the ultrasonic power supply 11 reaches the minimum output power and the impact strength of the jet body 2 is still greater than the preset impact strength, the controller 5 controls the air flow of the positive pressure air source 4 to be continuously reduced so as to further reduce the impact strength of the jet body 2 until the air flow of the positive pressure air source 4 reaches the minimum air flow.
