Description

Technical Field

[0001] The utility model relates to the technical field of mold polishing, in particular to a pneumatic ultrasonic polishing machine for mold polishing. Background Technique

[0002] An ultrasonic polishing machine is a device that uses ultrasonic vibration for surface processing of materials. It is mainly used for the processing and polishing of hard and brittle materials and non-metallic materials. When the ultrasonic polishing machine polishes a mold, due to the heavy weight of the mold, a crane is required for handling. During the hoisting process, it is easy to collide with the tool head and cause damage to the tool head. Moreover, the mold is not convenient to move during polishing.

[0003] Based on the above problems, the patent with the publication number CN216098238U discloses a pneumatic ultrasonic polishing machine for mold polishing. By starting the pneumatic cylinder, the base and the slider move forward, thus moving away from the tool head. In this way, when handling the mold, the probability of the mold colliding with the tool head can be reduced, thereby reducing potential hazards. Then, by using the pneumatic cylinder to drive the base and the slider to move backward, the mold is moved to the lower end of the tool head. After that, by starting the ultrasonic generator, the ultrasonic generator generates high-frequency sound signals and transmits them to the ultrasonic transducer. Then, through the conversion of the ultrasonic transducer, the tool head vibrates, and thus the mold can be polished. In addition, by controlling the motor and the electric cylinder respectively, the slider can be rotated and lifted up and down, thus facilitating the polishing of the mold.

[0004] However, when implementing the above-mentioned pneumatic ultrasonic polishing machine for mold polishing, it is found that it at least still has the following problems. During the process of the tool head polishing the workpiece to be polished on the disc, it is necessary for the pneumatic cylinder to drive the base and the slider to slide, thus moving away from the tool head and then hoisting the mold. After the mold hoisting is completed, the base and the slider are returned to the bottom of the tool head through the pneumatic cylinder before polishing can be carried out. However, this results in a certain hoisting blank period. During the process of hoisting the mold, the tool head cannot carry out polishing, and the interval of the hoisting blank period affects the polishing efficiency. The shorter the interval of the hoisting blank period, the higher the polishing efficiency, and vice versa. Therefore, its polishing efficiency still needs to be improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment: Please refer to Figures 1 to 6 , a technical solution is provided according to an embodiment of the present utility model: a pneumatic ultrasonic polishing machine for mold polishing, including: a machine body 1, an ultrasonic polishing mechanism, a first shuttle platform, a second shuttle platform, and a driving structure. The ultrasonic polishing mechanism includes a frame body 5, an ultrasonic transducer 6, and a tool head 7. The frame body 5 can be fixed to the machine body 1 by bolts or welding. Both the ultrasonic transducer 6 and the tool head 7 are fixed to the frame body 5. The first shuttle platform includes a U-shaped support frame 8 and a driving block one 9. Both ends of the opening of the support frame 8 are slidably connected to the movable chute 4. The second shuttle platform includes a support plate 10. The support plate 10 is slidably connected to the sinking chute 2. An electric push rod 11 is fixed to the bottom of the support plate 10, and a driving block two 12 is provided at the bottom of the electric push rod 11. A sinking chute 2 is opened at the top of the machine body 1 to enable the second shuttle platform to slide in the sinking chute 2. An installation cavity 3 and a movable chute 4 are opened in the machine body 1 to enable the first shuttle platform to slide in the movable chute 4. The first shuttle platform and the second shuttle platform are driven to move back and forth by a driving structure installed in the installation cavity 3 and the sinking chute 2. Moreover, the electric push rod 11 in the second shuttle platform can push the support plate 10 to move up and down. When the support plate 10 moves downward, the support plate 10 can pass through between the support frames 8. When the support plate 10 moves upward, the support plate 10 is on the same horizontal plane as the support frames 8. When the support plate 10 and the support frames 8 are on the same horizontal plane, the tool head 7 polishes the TNK-LOGO special mold placed on the support plate 10. It should be noted that the driving structure can be a lead screw motor or an electric push rod, etc.

[0030] The pneumatic ultrasonic polishing machine for die polishing adopting the above structure, by setting the first shuttle platform and the second shuttle platform and driving through the driving structure, when polishing the die, the TNK-LOGO special die can be placed on the support frame 8 of the first shuttle platform, and the support frame 8 is driven by the driving structure to move to the bottom of the ultrasonic polishing mechanism for polishing. During the polishing process, the subsequent TNK-LOGO special die can be placed on the support plate 10 of the second shuttle platform, so as to carry out hoisting during the polishing process, reduce the hoisting blank period. When the polishing of the TNK-LOGO special die on the support frame 8 is completed, the driving structure drives the support frame 8 to retract, and at the same time, the driving structure drives the TNK-LOGO special die to be polished on the support plate 10 to pass through the bottom of the support frame 8, so that the support plate 10 and the TNK-LOGO special die to be polished on the support plate 10 are located at the bottom of the ultrasonic polishing mechanism. At this time, the electric push rod 11 pushes the support plate 10 to move up, so that the support plate 10 and the support frame 8 are on the same horizontal plane. Then, the ultrasonic polishing mechanism polishes the TNK-LOGO special die to be polished. After the polishing is completed, the electric push rod 11 drives the support plate 10 to retract, and the support frame 8 resets to polish again.

[0031] In this embodiment, the driving structure includes a motor 13 and a threaded lead screw 14. The threaded lead screw 14 is rotationally connected to the machine body 1. The driving block one 9 and the driving block two 12 are threadedly connected to the threaded lead screw 14, and the motor 13 provides power for the threaded lead screw 14. During the forward and reverse rotation of the threaded lead screw 14, the driving block one 9 or the driving block two 12 is driven to move back and forth.

[0032] In this embodiment, in order to prevent wear on the tops of the support frame 8 and the support plate 10, polishing trays 15 are fixed on the tops of the support frame 8 and the support plate 10. By placing the TNK-LOGO special die on the polishing trays 15, wear on the support frame 8 and the support plate 10 is reduced.

[0033] In this embodiment, during the slow driving of the support frame 8 and the support plate 10 by the driving mechanism, in order to prevent the TNK-LOGO special die from falling and deviating, anti-drop protrusions 16 are provided on the periphery of the polishing tray 15, so as to prevent the TNK-LOGO special die from falling. At the same time, an anti-slip pad 17 is adhered to the top of the polishing tray 15. When the TNK-LOGO special die is placed in the polishing tray 15, the TNK-LOGO special die can abut against the anti-slip pad 17, so as to reduce the deviation caused by sliding during the movement.

[0034] In this embodiment, to further increase the stability of the second shuttle platform during the sliding process, sliding plates 18 are fixedly installed on both sides of the sinking chute 2, such that the support plate 10 slides on the top of the sliding plates 18. A limiting chute 19 is formed in the sliding plates 18, and an installation plate 20 that slides in the limiting chute 19 is provided. By providing multiple limiting posts 22 fixed to the bottom of the support plate 10, and sliding holes 23 adapted to the multiple limiting posts 22 are formed in the installation plate 20, so that the installation plate 20 and the support plate 10 maintain stability during the sliding process. Moreover, an installation bracket 21 is provided at the bottom of the installation plate 20, the electric push rod 11 is fixed on the installation bracket 21, and by fixing the second driving block 12 to the bottom of the installation bracket 21, it is avoided that the electric push rod 11 deviates due to being directly fixed to the second driving block 12. The stability of the second shuttle platform during the sliding process can be effectively increased by the sliding plates 18, the installation plate 20, and the multiple limiting posts 22.

[0035] In this embodiment, a sliding track 24 is formed on the side of the sliding plate 18 facing the support plate 10, and rollers 25 are fixed on the support plate 10. When the support plate 10 is pushed down by the electric push rod 11, the rollers 25 enter the sliding track 24, and the support plate 10 is supported by the rollers 25, reducing the wear between the support plate 10 and the sliding plates 18 and increasing the smoothness during the sliding process.

[0036] In this embodiment, multiple limiting frames 26 are provided in the installation cavity 3. Limiting sliders 27 are provided on both sides of the opening of the support frame 8 of the support frame 8, and a limiting track 28 for the limiting sliders 27 to be embedded and slide is provided on the limiting frame 26. Thus, the support frame 8 is supported by the limiting frame 26, and due to the limiting track 28 and the limiting sliders 27, the support frame 8 can slide back and forth along the limiting track 28.

[0037] Working principle: When polishing the special TNK-LOGO mold to be polished, the special TNK-LOGO mold to be polished can be placed in the polishing tray 15 on the support frame 8. The rotation of the motor 13 drives the threaded lead screw 14 to rotate, thereby driving the first driving block 9 to move towards the bottom of the tool head 7. The ultrasonic transducer 6 converts the input ultra-audio electrical signal into mechanical vibration and transmits it to the tool head 7. The tool head 7 polishes the special TNK-LOGO mold to be polished. During the polishing process of the tool head 7, the subsequent special TNK-LOGO mold to be polished is hoisted and placed in the polishing tray 15 on the support plate 10 for preparation. When the polishing of the special TNK-LOGO mold to be polished on the support frame 8 is completed, the rotation of the motor 13 drives the threaded lead screw 14 to rotate, thereby driving the first driving block 9 to reset. At the same time, the rotation of the motor 13 drives the threaded lead screw 14 to rotate, driving the second driving block 12 to move towards the ultrasonic polishing mechanism. When the special TNK-LOGO mold to be polished on the support plate 10 is located at the bottom of the tool head 7, the electric push rod 11 drives the support plate 10 and the special TNK-LOGO mold to be polished to move upward, so that the support plate 10 and the support frame 8 are on the same horizontal plane. At this time, the tool head 7 polishes the special TNK-LOGO mold to be polished on the support plate 10. At the same time, the subsequent special TNK-LOGO mold to be polished can continue to be placed in the polishing tray 15 on the support frame 8. After the polishing of the special TNK-LOGO mold to be polished on the support plate 10 is completed, it is polished again.
