Technical Field
[0001] This utility model relates to the field of crankshaft processing technology, and in particular to an ultrasonic impact strengthening device for high-precision wear-resistant crankshafts. Background Technology
[0002] Crankshafts are key components in mechanical transmission systems, mainly used to convert rotary motion into reciprocating motion or vice versa. They are commonly found in equipment such as engines and compressors. During the machining process of crankshafts, high-frequency shock waves are used to improve the surface properties of the crankshafts, thereby improving their precision and wear resistance. Therefore, a high-precision wear-resistant crankshaft ultrasonic shock strengthening device is used.
[0003] Existing ultrasonic impact strengthening devices for high-precision wear-resistant crankshafts are inconvenient to use, making it difficult to quickly fix the crankshaft to improve work efficiency, and also making it difficult to avoid the impact point shifting due to crankshaft wobbling. Utility Model Content
[0004] The purpose of this invention is to provide an ultrasonic impact strengthening device for high-precision wear-resistant crankshafts, in order to solve the defect of existing ultrasonic impact strengthening devices for high-precision wear-resistant crankshafts being inconvenient to fix.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an ultrasonic impact strengthening device for a high-precision wear-resistant crankshaft, including a base;
[0006] A rotating structure is fixed to one side of the top of the base, and a clamping mechanism is fixed to one side of the rotating structure.
[0007] The clamping mechanism includes a support frame fixed to one side of the rotating structure. A second electric push rod passes through one side of the top of the support frame. A movable plate is fixed to the bottom end of the second electric push rod. Both ends of one side of the movable plate are hinged to hinge rods. One end of each hinge rod is hinged to a movable plate. A clamping seat is fixed to one side of the bottom of the movable plate.
[0008] A crankshaft body is provided on one side of the clamping mechanism, and a movable structure is fixed to the top of the base on one side of the crankshaft body.
[0009] When using this device, the clamping mechanism enables quick and easy fixing, thereby improving the working efficiency of the ultrasonic impact strengthening device for high-precision wear-resistant crankshafts. The movable structure facilitates changing the strengthening position, enhancing the ease of use. The rotating structure facilitates uniform strengthening, improving the applicability of the ultrasonic impact strengthening device for high-precision wear-resistant crankshafts.
[0010] Preferably, the movable structure includes a fixed frame, a threaded rod, a fixed plate, a servo motor, a movable seat, a guide seat, a first electric push rod, a slide rod, an ultrasonic generator, a transducer, an amplitude transformer, and an impact head. The fixed frame is fixed to the top of the base. A threaded rod is provided on the top of the fixed frame. The movable seat is threadedly connected to the outer side of the threaded rod. A guide seat is fixed to the top of the movable seat. A fixed plate is fixed to the bottom of the movable seat. The first electric push rod passes through the interior of the fixed plate. An ultrasonic generator is fixed to one end of the first electric push rod. A transducer is provided at one end of the ultrasonic generator. An amplitude transformer is fixed to one end of the transducer. An impact head is fixed to one end of the amplitude transformer. A servo motor is installed on the outer wall of the fixed frame at one end of the threaded rod. Slide rods pass through the interiors of the fixed plates on both sides of the first electric push rod. Under the action of the guide seat and the guide groove, the movable seat is prevented from rotating with the threaded rod. After moving, the movable seat drives the impact head to move through the fixed plate, realizing a large range of horizontal position adjustment of the impact head.
[0011] Preferably, one end of the threaded rod extends to the outside of the fixed frame and is fixedly connected to the output end of the servo motor. A guide groove is provided inside the fixed frame above the guide seat. The guide seat and the fixed frame form a sliding structure through the guide groove. The slide rod and the fixed plate also form a sliding structure. One end of the slide rod is fixedly connected to one end of the ultrasonic generator. Under the action of the slide rod, the stability of the ultrasonic generator during movement is enhanced. The moved ultrasonic generator drives the impact head to move, realizing the vertical feed of the impact head and adapting to the different radial strengthening requirements of the crankshaft body. When the impact head contacts the surface of the crankshaft body, the crankshaft body is strengthened through high-frequency impact.
[0012] Preferably, the rotating structure includes a fixed base, a drive motor, a movable slot, a driven gear, a turntable, a connecting shaft, and a drive gear. The fixed base is fixed to one side of the top of the base. The top of the fixed base is provided with a movable slot, and the bottom of the movable slot is provided with a drive gear. The top of the drive gear is meshed with the driven gear. A connecting shaft is fixed to one side of the driven gear, and one end of the connecting shaft extends to the outside of the fixed base and is fixed to the turntable. The drive motor is installed on the outer wall of the fixed base on the side of the drive gear. When the drive gear drives the driven gear to rotate, the driven gear drives the turntable to rotate through the connecting shaft, causing the turntable to drive the crankshaft body to rotate through the clamping seat.
[0013] Preferably, the output end of the drive motor extends into the interior of the movable groove and is fixedly connected to one side of the drive gear, and one side of the turntable is fixedly connected to one side of the support frame. This enables circumferential rotation of the crankshaft body, allowing ultrasonic impact to cover the entire circumferential surface of the crankshaft body and ensuring uniform reinforcement.
[0014] Preferably, both ends of the movable plate away from the clamping seat are fixed with slide blocks, and a slide rail runs through one side of each slide block. The movable plate is raised and lowered by a second electric push rod, causing the movable plate to move in the opposite direction via a hinged rod. The slide rail and slide blocks enhance the stability of the movable plate during movement.
[0015] Preferably, the slide block and the slide rail form a sliding structure. One side of the slide rail is fixedly connected to one side of the support frame. Anti-slip pads are fixed to both ends of one side of the clamping seat. The clamping seat abuts against one side of the crank shaft body via the anti-slip pads. After movement, the movable plate, through the clamping seat, drives the anti-slip pads to clamp onto one side of the crank shaft body. The anti-slip pads increase the friction between the clamping seat and the crank shaft body, facilitating quick fixation of the crank shaft body and preventing the impact point from shifting due to shaking.
[0016] The ultrasonic impact strengthening device for a high-precision wear-resistant crankshaft provided by this utility model has the following advantages:
[0017] By incorporating a clamping mechanism, the moving plate is raised and lowered via a second electric push rod. This causes the moving plate to move in the opposite direction via a hinge rod. The stability of the moving plate during movement is enhanced by the slide rail and slide block. After movement, the moving plate is clamped to one side of the crankshaft body via the clamping seat and anti-slip pad. The anti-slip pad increases the friction between the clamping seat and the crankshaft body, facilitating quick fixation of the crankshaft body. This also prevents the impact point from shifting due to shaking of the crankshaft body, thus achieving the function of quick fixation and improving the working efficiency of the ultrasonic impact strengthening device for high-precision wear-resistant crankshafts.
[0018] By incorporating a movable structure, the movable seat is prevented from rotating along with the threaded rod under the action of the guide seat and guide groove. After moving, the movable seat drives the impact head to move through the fixed plate, realizing a wide range of horizontal position adjustment of the impact head. Under the action of the slide rod, the stability of the ultrasonic generator during movement is enhanced. After moving, the ultrasonic generator drives the impact head to move, realizing the vertical feed of the impact head, adapting to the different radial strengthening requirements of the crankshaft body. When the impact head contacts the surface of the crankshaft body, the crankshaft body is strengthened through high-frequency impact. This realizes the function of easy replacement of the strengthening position of the device, thereby improving the convenience of use of the ultrasonic impact strengthening device for high-precision wear-resistant crankshaft.
[0019] By incorporating a rotating structure, when the driving gear drives the driven gear to rotate, the driven gear drives the turntable to rotate via the connecting shaft. This causes the turntable to drive the crankshaft body to rotate via the clamping seat, thereby achieving circumferential rotation of the crankshaft body. This allows the ultrasonic impact to cover the entire circumferential surface of the crankshaft body, ensuring uniform strengthening and realizing the function of facilitating uniform strengthening. This improves the applicability of the ultrasonic impact strengthening device for high-precision wear-resistant crankshafts in use. Attached Figure Description

[0029] Please see Figures 1-7 This utility model provides an ultrasonic impact strengthening device for a high-precision wear-resistant crankshaft, comprising a base 1, a rotating structure 3 fixed to one side of the top of the base 1, the rotating structure 3 including a fixed seat 301, a drive motor 302, a movable groove 303, a driven gear 304, a turntable 305, a connecting shaft 306, and a driving gear 307. The fixed seat 301 is fixed to one side of the top of the base 1, the top of the fixed seat 301 is provided with the movable groove 303, and the bottom of the movable groove 303 is provided with the driving gear 307. The top of the driving gear 307 is meshed with the driven gear 304. A connecting shaft 306 is fixed to one side of the driven gear 304. One end of the connecting shaft 306 extends to the outside of the fixed base 301 and is fixed with a turntable 305. A drive motor 302 is installed on the outer wall of the fixed base 301 on one side of the driving gear 307. The output end of the drive motor 302 extends into the interior of the movable groove 303 and is fixedly connected to one side of the driving gear 307. One side of the turntable 305 is fixedly connected to one side of the support frame 401.
[0030] Reference Figure 5 and Figure 6 As shown, when the drive motor 302 is started, the active gear 307 rotates inside the movable groove 303. The active gear 307 drives the driven gear 304 to rotate, and the driven gear 304 drives the turntable 305 to rotate through the connecting shaft 306. The turntable 305 drives the crankshaft body 5 to rotate through the clamping seat 407, thereby realizing the circumferential rotation of the crankshaft body 5. This allows the ultrasonic impact to cover the entire circumferential curved surface of the crankshaft body 5, ensuring the uniformity of the reinforcement.
[0031] A clamping mechanism 4 is fixed to one side of the rotating structure 3. The clamping mechanism 4 includes a support frame 401 fixed to one side of the rotating structure 3.

One side of the slide rail 404 is fixedly connected to one side of the support frame 401. Anti-slip pads are fixed to both ends of one side of the clamping seat 407. The clamping seat 407 abuts against one side of the crank shaft body 5 through the anti-slip pads.
[0032] Reference Figure 5 , Figure 6 and Figure 7 As shown, activating the second electric push rod 402 causes the movable plate 403 to rise and fall. The movable plate 403 then drives the movable plate 406 to move in the opposite direction via the hinge rod 408. The movable plate 406 then drives the slide block 405 to move outside the slide rail 404. Under the action of the slide rail 404 and the slide block 405, the stability of the movable plate 406 during movement is enhanced. After moving, the movable plate 406 drives the anti-slip pad to clamp onto one side of the crank shaft body 5 via the clamping seat 407. Under the action of the anti-slip pad, the friction between the clamping seat 407 and the crank shaft body 5 is increased, thereby facilitating the quick fixation of the crank shaft body 5 and preventing the impact point from shifting due to shaking of the crank shaft body 5.
[0033] A crankshaft body 5 is provided on one side of the clamping mechanism 4. A movable structure 2 is fixed to the top of the base 1 on one side of the crankshaft body 5. The movable structure 2 includes a fixed frame 201, a threaded rod 202, a fixed plate 203, a servo motor 204, a movable seat 205, a guide seat 206, a first electric push rod 207, a slide rod 208, an ultrasonic generator 209, a transducer 210, an amplitude transformer 211, and an impact head 212. The fixed frame 201 is fixed to the top of the base 1. A threaded rod 202 is provided on the top of the fixed frame 201. The outer side of the threaded rod 202 is threadedly connected to the movable seat 205. The top of the movable seat 205 is fixed to the guide seat 206. The bottom of the movable seat 205 is fixed to the fixed plate 203. The first electric push rod 207 passes through the interior of the fixed plate 203. One end of the first electric push rod 207 is fixed. An ultrasonic generator 209 is provided, with a transducer 210 at one end of the ultrasonic generator 209. An amplitude transformer 211 is fixed to one end of the transducer 210, and an impact head 212 is fixed to one end of the amplitude transformer 211. A servo motor 204 is installed on the outer wall of a mounting bracket 201 at one end of a threaded rod 202. Slide rods 208 pass through the interior of the mounting plates 203 on both sides of the first electric push rod 207. One end of the threaded rod 202 extends to the outside of the mounting bracket 201 and is fixedly connected to the output end of the servo motor 204. A guide groove is provided inside the mounting bracket 201 above the guide seat 206. The guide seat 206 and the mounting bracket 201 form a sliding structure through the guide groove. The slide rod 208 and the mounting plate 203 form a sliding structure. One end of the slide rod 208 is fixedly connected to one end of the ultrasonic generator 209.
[0034] Reference Figure 3 and Figure 4As shown, the servo motor 204 is started, causing the threaded rod 202 to rotate. Simultaneously, the threaded rod 202 drives the movable seat 205 to move. The movable seat 205 then drives the guide seat 206 to move within the guide groove. Under the action of the guide seat 206 and the guide groove, the movable seat 205 is prevented from rotating along with the threaded rod 202. After moving, the movable seat 205 drives the impact head 212 to move via the fixed plate 203, achieving a wide range of horizontal position adjustment for the impact head 212. The first electric push rod 207 is then started, driving the ultrasonic generator 209 to move. The ultrasonic generator 209 then drives the slide rod 208 to move within the fixed plate 203. The sliding rod 208 enhances the stability of the ultrasonic generator 209 during movement. The moved ultrasonic generator 209 drives the impact head 212 to move, enabling the impact head 212 to feed in the vertical direction and adapt to the different radial strengthening requirements of the crankshaft body 5. The ultrasonic generator 209 converts electricity into high-frequency electrical signals, and the transducer 210 receives the high-frequency electrical signals. Through the piezoelectric effect, the electrical energy is converted into high-frequency mechanical vibration. The amplitude rod 211 amplifies the vibration amplitude, making the vibration energy more concentrated and providing sufficient impact force for the impact head 212. When the impact head 212 contacts the surface of the crankshaft body 5, the high-frequency impact strengthens the crankshaft body 5.
