Abstract
Description
Technical Field
[0001] This utility model relates to the field of gear ring forging technology, and in particular to an automatic flash cleaning device for gear ring forging. Background Technology
[0002] Flash on gear ring forgings refers to the excess metal that flows into the flash groove during the forging process, forming a ring of metal around the forging. Flash plays a role in ensuring that the metal fills the die cavity during the die forging process and needs to be removed after forging is completed.
[0003] The device for automatic cleaning of flash from gear ring forgings is mainly designed for gear rings of a specific size. It is not very adaptable to gear rings of different sizes. When it is necessary to clean gear rings of different sizes, it is necessary to change the corresponding mold or adjust the equipment settings, which increases production time and cost. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic flash cleaning device for gear ring forgings.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An automatic flash cleaning device for gear ring forgings includes a base, a fixed plate fixedly connected to the top of the base, a fixed frame rotatably connected to one side of the fixed plate, multiple slide tracks opened on one side of the fixed frame, slide columns slidably connected in the slide tracks, a rotating plate rotatably connected to the bottom of the slide columns via a rotating shaft, a lead screw rotatably connected to the inner wall of one side of the fixed frame at its center via a bearing, a limit plate threadedly connected to the outer side of the lead screw, multiple connecting blocks rotatably connected to the multiple rotating plates fixedly connected to the outer side of the limit plate, a grinding assembly for the gear ring provided on the top of the base, and a second motor for driving the fixed frame to rotate fixedly connected to one side of the fixed plate.
[0007] As a further embodiment of this utility model, the fixed frame is fixedly connected to a connecting plate that is threadedly connected to the lead screw at the middle position of the frame.
[0008] As a further embodiment of this utility model, the polishing assembly includes a placement frame fixedly connected to the top of the base, a stop frame fixedly connected to the top of the placement frame, a sliding groove opened on one side of the stop frame, two sliders slidably connected in the sliding groove, a first motor fixedly connected to one side of the slider, a rotating rod connected to one end of the output shaft of the first motor through a coupling, and a polishing rod detachably connected to one end of the rotating rod through the slider rotatably connected thereto and by bolts.
[0009] As a further embodiment of this utility model, the inner walls of both sides of the baffle are rotatably connected by bearings to bidirectional threaded rods that are threadedly connected to the two sliders, and one end of the bidirectional threaded rod passes through the baffle and is fixedly connected to a knob.
[0010] As a further improvement of this utility model, each of the two sliders has two slots at its bottom, and a rolling roller is rotatably connected inside the slots.
[0011] As a further improvement of this utility model, anti-slip pads are fixedly connected to the outer sides of each of the multiple sliders.
[0012] As a further embodiment of this utility model, the top of the base is provided with a discharge port, and the bottom inner wall of the base is slidably connected with a waste bin of the same size as the discharge port.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model achieves the support and fixation of gear rings of different sizes through the cooperation of sliders, rotating plates and lead screws. By rotating the lead screw to adjust the angle of the rotating plate, the distance between multiple sliders can be changed, which is convenient for clamping gear rings of different diameters.
[0015] 2. This utility model achieves the removal of flash from the gear ring through the cooperation of a slider, a first motor, and a grinding rod. The first motor drives the rotation of the grinding rod to achieve a highly efficient and uniform grinding effect. Because the grinding rod directly contacts the flash area of the gear ring, it rotates at high speed with the help of the power provided by the first motor, thereby physically removing the flash.
[0016] 3. This utility model, through the provision of a bidirectional threaded rod, enables convenient adjustment of the distance between the sliders, allowing the grinding rod to precisely act on the position requiring grinding, thereby achieving convenience and efficiency in grinding the burrs on the gear ring.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.
[0023] Reference Figures 1-4An automatic flash cleaning device for gear ring forgings includes a base 6. A discharge port 4 is located at the top of the base 6. A waste bin 5, the same size as the discharge port 4, is slidably connected to the inner wall of the bottom of the base 6. During gear ring grinding, the flash and waste generated automatically enter the waste bin 5 through the discharge port 4 for centralized collection, effectively reducing pollution in the work area. A fixing plate 7 is bolted to the top of the base 6. A fixing frame 1 is rotatably connected to one side of the fixing plate 7. A connecting disc 18, threadedly connected to a lead screw 16, is bolted to the inner wall of the fixing frame 1 at the center of the frame. The connecting disc 18 not only enhances the overall support stability of the fixing frame 1 but also acts as a guide, effectively preventing the lead screw 16 from shifting during rotation. Multiple slide rails 22 are provided on one side of the fixing frame 1. Sliding columns 8 are slidably connected within the slide rails 22. A rotating plate 21 is rotatably connected to the bottom of the sliding column 8 via a rotating shaft. A lead screw 16 is rotatably connected to the inner wall of one side of the fixing frame 1 at the center via a bearing. The outer thread of screw 16 is connected to a limiting plate 20. The outer side of the limiting plate 20 is fixed with multiple connecting blocks 17 that are rotatably connected to multiple rotating plates 21. The side of the fixing plate 7 is fixed with a second motor 19 that drives the fixing frame 1 to rotate. First, the size of the toothed ring to be cleaned of the flash is determined according to the requirements. The limiting plate 20 is moved up and down by the handle at one end of the screw 16. When the handle is turned clockwise, the limiting plate 20 will move down along the clockwise direction of the screw 16. At the same time, multiple sliding columns 8 will slide along the direction of the slide 22 towards the center of the outer wall of the fixing frame 1, forming a contracted state. Then the toothed ring is placed on the outside of the multiple sliding columns 8. Then the handle is turned counterclockwise, and the sliding columns 8 gradually unfold outward until their outer sides are close to the inner wall of the toothed ring, forming a stable support state. Then the second motor 19 on the side of the fixing plate 7 is used to drive the overall rotation of the fixing frame 1, so that the toothed ring is stably clamped and rotated. Finally, the grinding component on the base 6 is used to clamp, grind and clean the flash of toothed rings of different sizes.
[0024] In this invention, the base 6 has a grinding assembly for the gear ring on its top. The grinding assembly includes a mounting bracket 3 fixed to the top of the base 6 by bolts. A stop bracket 2 is fixed to the top of the mounting bracket 3 by bolts. Two bidirectional threaded rods 12, which are threadedly connected to two sliders 14, are rotatably connected to the inner walls of the two sides of the stop bracket 2 via bearings. One end of the bidirectional threaded rod 12 passes through the stop bracket 2 and is fixed with a knob by bolts. When grinding is not being performed, one side of the two sliders 14 is in contact with the inner walls of the two sides of the stop bracket 2, keeping the distance between the two sliders 14 at its maximum. The function of the bidirectional threaded rod 12 is to push the two sliders 14 to retract or expand synchronously by rotating the knob at one end. When the two sliders 14 move synchronously to the outside of the grinding rod 9 and contact the gear ring, the first motor 11 drives the grinding rod 9 mounted on it to rotate at high speed, thereby cleaning and grinding the surface burrs of the gear ring. A groove 13 is provided on one side of the stop bracket 2. Two sliders 14 are slidably connected in the groove 13. Two slots are provided at the bottom of each slider 14. A rolling roller 15 is dynamically connected to the slider 14. The sliding of the rolling roller 15 at the bottom of the slider 14 on the inner wall of the bottom of the stop 2 significantly reduces the coefficient of friction between the slider 14 and the stop 2, thereby reducing the resistance and wear of the slider 14 during movement. A first motor 11 is fixed to one side of the slider 14 by bolts. One end of the output shaft of the first motor 11 is connected to a rotating rod 10 through a coupling. One end of the rotating rod 10 passes through the slider 14 to which it is rotatably connected and is detachably connected to a grinding rod 9 by bolts. The two first motors 11 are used to drive their respective output shafts, thereby driving the rotating rod 10 connected to them to rotate. The rotation of the rotating rod 10 directly causes the grinding rod 9 to rotate at high speed, so that the two grinding rods 9 can efficiently and evenly complete the grinding task of the gear ring. Anti-slip pads are glued to the outer side of multiple sliders 14. The anti-slip pads are made of polyvinyl chloride. During the movement of the slider 14, the polyvinyl chloride anti-slip pads increase the friction with the inner wall of the gear ring, reducing the shaking and displacement of the gear ring during grinding and enhancing the stability of the gear ring acting on the slider 14.
[0025] Working principle: When it is necessary to remove the flash from the toothed ring forging, firstly, the toothed ring size to be cleaned is determined according to the required flash size. The limit plate 20 is moved up and down by the handle at one end of the lead screw 16. When the handle is turned clockwise, the limit plate 20 will move downward along the clockwise direction of the lead screw 16. At the same time, multiple sliding columns 8 will slide along the direction of the slide rail 22 towards the center of the outer wall of the fixed frame 1, forming a contracted state. Then, the toothed ring is placed on the outside of the multiple sliding columns 8. Then, the handle is turned counterclockwise, and the sliding columns 8 gradually expand outward until their outer sides are close to the inner wall of the toothed ring, forming a stable support state. At the same time, the knob at one end of the bidirectional threaded rod 12 is turned to make the two sliders 14 retract or expand synchronously. When the two sliders 14 move synchronously to the outside of the grinding rod 9 and contact the toothed ring, the first motor 11 is driven to drive the grinding rod 9 mounted on it to rotate at high speed. Then, the second motor 19 on one side of the fixed plate 7 is driven to realize the rotation of the entire fixed frame 1, thereby realizing the automatic cleaning of the flash of the toothed ring.
[0026] In this application, an annular groove is provided axially inside the limiting plate 20, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the lead screw 16 at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.
