Description

Technical Field

[0001] This invention relates to the field of metal parts processing equipment, specifically to an ultrasonic rolling device for metal parts. Background Technology

[0002] Ultrasonic rolling is a composite special processing technology that utilizes ultrasonic waves. The surface of the processed parts is refined and the metallographic structure is more uniform. It solves the shortcomings of traditional processing technology in this regard and can achieve the effect of "shaving peaks and filling valleys". It can improve the surface integrity, corrosion resistance, wear resistance and fatigue resistance of the processed workpiece.

[0003] During ultrasonic rolling, the workpiece needs to be leveled before clamping. To ensure the workpiece surface is level, a dial indicator is typically fixed to the machine tool's moving arm with its contact point in contact with the workpiece surface, and then the dial indicator is zeroed. By moving the machine tool's moving arm, the dial indicator moves along the X and Y axes. The change in the dial indicator's pointer is observed during this movement to determine if the workpiece is level. This measurement method requires continuous observation of the dial indicator's readings during its movement; however, continuous observation is inconvenient and inefficient. Summary of the Invention

[0004] The technical problem to be solved by this invention is an ultrasonic rolling device that can improve the efficiency of workpiece leveling. The ultrasonic rolling device of this invention facilitates the measurement of the levelness of the workpiece, thereby improving the processing efficiency of metal parts.

[0005] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0006] An ultrasonic rolling device for metal parts includes a horizontal connecting plate with a rotating seat mounted on its upper end. An electric telescopic rod is fixed to one side of the lower end of the connecting plate, and an ultrasonic rolling device is mounted on the other side of the lower end of the connecting plate via an electric push rod. A fixed plate is fixed to the telescopic rod. The device is characterized by having multiple inclined movable rods hinged to the lower end of the fixed plate. These inclined movable rods are evenly distributed around the circumference of the fixed plate's axis. Adjacent movable rods are connected via a ranging component, which allows for the measurement of the distance between the ranging component and the connection point of the two movable rods. The device also includes a support base located below the fixed plate, with the workpiece resting on the upper end of the support base. Multiple support adjustment devices for leveling the workpiece are evenly distributed around the circumference of the support base.

[0007] Specifically, a rotating shaft is fixedly connected to the top of the movable rod. The rotating shaft is rotatably connected to the fixed plate through a hinge seat. A limiting groove is provided on the outer side of the hinge seat. A slider is fixedly connected to the rotating shaft of the movable rod. The slider is slidably connected to the limiting groove. The cooperation between the limiting groove and the slider is used to restrict the lower end of the movable rod from rotating in the direction of the axis of the fixed plate. The movable rod is in an inclined state.

[0008] Specifically, the ranging assembly includes an elastic tube, with a laser rangefinder and a laser receiver fixed at both ends of the elastic tube, respectively. The laser emitted by the laser rangefinder is allowed to pass through the elastic tube and be received by the laser receiver. A first pull rope and a second pull rope are fixed to the laser rangefinder and the laser receiver, respectively. The first pull rope is fixedly connected to a movable rod on one side, and the second pull rope is fixedly connected to a movable rod on one side. The length from the connection point of the first pull rope to the movable rod on one side to the lower end of the movable rod is L, and the length from the connection point of the second pull rope to the movable rod on one side to the lower end of the movable rod is L.

[0009] Specifically, the support adjustment device includes a pad installed on a support base. A rectangular groove is provided on the support base, and the pad is slidably connected in the rectangular groove. A threaded rod is threadedly connected in the pad, and the lower end of the threaded rod is rotatably connected to the support base. A first bevel gear is fixed on the threaded rod below the pad. A connecting rod corresponding to and perpendicular to the threaded rod is rotatably connected to the support base. One end of the connecting rod extends into the rectangular groove, and the other end extends to the outside of the support base. A second bevel gear is fixed to one end of the connecting rod in the rectangular groove. The second bevel gear meshes with the first bevel gear. A handwheel is fixed to one end of the connecting rod on the outside of the support base.

[0010] Specifically, the rotating seat is located at the middle of the upper end of the connecting plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. When measuring the levelness of a workpiece, this invention controls multiple movable rods to descend simultaneously via an electric telescopic rod, causing the lower ends of the multiple movable rods to contact the upper end of the workpiece. The distance between the movable rods is measured by a distance measuring component, and the workpiece is determined to be level based on the measured data. Therefore, the efficiency of measuring the levelness of a workpiece is high.

[0013] 2. When measuring the distance between the movable rods, the laser emitter and laser receiver are used together to measure the distance between the movable rods. The measurement data is accurate, the measurement speed is fast, and it saves time and effort.

[0014] 3. During the leveling process of the workpiece, the height of the shim is adjusted to level the workpiece. During the adjustment of the shim height, the data between the movable rods can be directly observed. When the distance between adjacent movable rods is equal, the adjustment of the shim height can be stopped, thus facilitating the leveling of the workpiece. Attached Figure Description

[0022] like Figures 1 to 5 As shown, an ultrasonic rolling device for metal parts includes a horizontally positioned connecting plate 1. A rotating seat 2 is mounted on the upper end of the connecting plate 1 and is fixedly connected to a machine tool. The rotating seat 2 is located in the middle of the upper end of the connecting plate 1. An electric telescopic rod 3 is fixed to one side of the lower end of the connecting plate 1. An ultrasonic rolling device 14 is mounted on the other side of the lower end of the connecting plate 1 via an electric push rod. A fixed plate 4 is fixed to the telescopic rod of the electric telescopic rod 3, and a plurality of inclined movable rods 5 are hinged to the lower end of the fixed plate 4. The plurality of inclined movable rods 5 are evenly distributed around the circumference of the axis of the fixed plate 4. In this embodiment, there are three movable rods 5.

[0023] A rotating shaft is fixedly connected to the top of the movable rod 5, and the rotating shaft is rotatably connected to the fixed plate 4 via a hinge seat 6. A limiting groove 7 is formed on the outer side of the hinge seat 6, and a slider 8 is fixedly connected to the rotating shaft of the movable rod 5. The slider 8 is slidably connected to the limiting groove 7. The cooperation between the limiting groove 7 and the slider 8 is used to restrict the lower end of the movable rod 5 from rotating towards the axis of the fixed plate 4, thereby ensuring that the movable rod 5 is in an inclined state. When the movable rod 5 moves downward and comes into contact with the surface of the workpiece, the lower end of the movable rod 5 is allowed to rotate away from the axis of the fixed plate 4 as the movable rod 5 moves downward. At the same time, the slider 8 slides within the limiting groove 7.

[0024] Two adjacent movable rods 5 are connected by a ranging assembly. The ranging assembly allows for the measurement of the distance between the ranging assembly and the connection point between the two movable rods 5. The distance between the connection point between the ranging assembly and the movable rod 5 and the lower end of the movable rod 5 is equal.

[0025] The ranging assembly includes an elastic tube 11. A laser rangefinder 10 and a laser receiver 12 are fixed to both ends of the elastic tube 11, respectively. The laser emitted by the laser rangefinder 10 is allowed to pass through the elastic tube 11 and be received by the laser receiver 12. A first pull rope 9 and a second pull rope 13 are fixed to the laser rangefinder 10 and the laser receiver 12, respectively. The first pull rope 9 is fixedly connected to a movable rod 5 on one side, and the second pull rope 13 is fixedly connected to the movable rod 5 on one side. The length from the connection point of the first pull rope 9 to the lower end of the movable rod 5 is L. The length from the connection point of the second pull rope 13 to the lower end of the movable rod 5 is L.

[0026] As the movable rod 5 descends and contacts the workpiece surface, the elastic tube 11 is stretched and stores force as the lower end of the movable rod 5 rotates away from the axis of the fixed plate 4. An electrical signal connection exists between the laser rangefinder 10 and the laser receiver 12. The laser rangefinder 10 and laser receiver 12 are used to determine the distance between two points, which is common knowledge technology.

[0027] The ultrasonic rolling device also includes a support base 16 located below the fixed plate 4. The support base 16 is fixed to the machine tool, and the workpiece 24 sits on the upper end of the support base 16. Multiple support adjustment devices for leveling the workpiece 24 are evenly distributed around the circumference of the support base 16. In this embodiment, there are three support adjustment devices.

[0028] The support adjustment device includes a pad 17 mounted on a support base 16. A rectangular groove 18 is formed in the support base 16. The pad 17 is slidably connected within the rectangular groove 18. A threaded rod 19 is threadedly connected to the pad 17, and the lower end of the threaded rod 19 is rotatably connected to the support base 16. A first bevel gear 20 is fixed to the threaded rod 19 below the pad 17. A connecting rod 22, corresponding to and perpendicular to the threaded rod 19, is rotatably connected to the support base 16. One end of the connecting rod 22 extends into the rectangular groove 18, and the other end extends to the outside of the support base 16. A second bevel gear 21 is fixed to one end of the connecting rod 22 within the rectangular groove 18, and the second bevel gear 21 meshes with the first bevel gear 20. A handwheel 23 is fixed to one end of the connecting rod 22 on the outside of the support base 16.

[0029] Place the workpiece 24 on the support base 16 and make the workpiece 24 supported by the pad 17 of the support base 16.

[0030] During operation, the rotating seat 2 rotates the connecting plate 1, positioning the fixed plate 4 above the workpiece 24. The electric telescopic rod 3 is activated, extending its extension and causing multiple movable rods 5 to move downwards. Once all movable rods 5 are in contact with the upper surface of the workpiece 24, the electric telescopic rod 3 is deactivated. The laser rangefinder is then activated to measure the distance between adjacent movable rods 5. If the distances between adjacent movable rods 5 are equal, it indicates that the workpiece 24 is horizontal. The machine tool vise 15 is then activated to clamp and fix the workpiece 24. The connecting plate 1 is then rotated, positioning the ultrasonic roller 14 above the workpiece 24. An electric push rod maintains a suitable distance between the ultrasonic roller 14 and the workpiece 24. The machine tool's movable arm is activated, and the ultrasonic roller 14 is turned on to begin processing the workpiece 24.

[0031] If the distance between two adjacent movable rods 5 is not equal, it indicates that the workpiece 24 is tilted. Conversely, the part of the workpiece 24 below the movable rod 5 is tilted upwards. Then, the workpiece 24 can be leveled by rotating the handwheel 23 to adjust the height of the shim 17. During the process of leveling the workpiece 24 by rotating the handwheel 23 to adjust the height of the shim 17, the change in the distance between two adjacent movable rods 5 can be observed. When the distance between two adjacent movable rods 5 is equal, the workpiece 24 is in a horizontal state.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
