Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment technology, and specifically relates to a roller seat inner hole grinding equipment. Background Technology

[0002] As a core supporting component of roller-type equipment, the roller holder is widely used in industrial fields such as metallurgical rolling mills, printing machinery, papermaking equipment, and plastics processing machinery. Its internal bore needs to achieve a high-precision fit with the roller journal. The dimensional accuracy (such as roundness and cylindricity) and surface roughness of the internal bore directly determine the assembly stability, operational concentricity, and service life of the roller. Therefore, the final critical process in roller holder machining is usually internal bore grinding, which aims to remove machining marks on the internal bore surface through micro-grinding, correct dimensional deviations, and meet stringent assembly requirements.

[0003] Problems with existing technology: Currently, the size adjustment flexibility of grinding heads is poor. Usually, one grinding head can only be used for one type of inner diameter hole. Different grinding heads need to be changed for different specifications of roller seat inner holes, which is cumbersome and inefficient. In addition, it is difficult to switch grinding parts with different roughness during the grinding process. If multiple processes such as rough grinding and fine grinding are required to process the same inner hole, the grinding parts need to be disassembled and replaced multiple times, which increases the complexity of operation. Utility Model Content

[0004] The purpose of this invention is to provide a roller seat inner hole grinding device that can adapt to roller seat inner holes of different inner diameters, without the need to replace the grinding head, thus greatly improving the versatility of the device.

[0005] The specific technical solution adopted by this utility model is as follows: A roller seat inner hole grinding device includes a worktable, a horizontal and vertical moving mechanism is provided on the top of the worktable, a motor is provided at the output end of the horizontal and vertical moving mechanism, and a grinding head mechanism is provided on the output shaft of the motor, which can switch between arc-shaped grinding plates with different roughness as needed. A clamping platform is provided on the worktable and below the grinding head for clamping the roller seat.

[0006] The grinding head mechanism includes a mounting base disposed at the motor output end, the mounting base being a cylindrical structure with an internal mounting cavity.

[0007] The inner bottom of the mounting cavity has at least three first sliding grooves arranged in a circumferential direction. A first slider slides inside the first sliding groove, and a first mounting shaft is rotatably mounted through the outer wall of the first slider.

[0008] A grinding adjustment seat is provided on the outer wall of the first mounting shaft and below the mounting base. The grinding adjustment seat is the main structure. At least three arc-shaped protrusions are arranged in a circumferential direction on the surface of the grinding adjustment seat. An arc-shaped grinding plate is fitted on the outer surface of the arc-shaped protrusions.

[0009] The surface roughness of the multiple arc-shaped grinding plates on the grinding adjustment seat is different.

[0010] A second connecting rod is rotatably mounted on the outer wall of the first mounting shaft and located within the mounting cavity. The other end of the second connecting rod is rotatably mounted on the first connecting rod. A second mounting shaft, rotatably connected to the first connecting rod, is rotatably mounted at the center of the interior of the mounting cavity.

[0011] A third gear is fixed on the outer wall of the first mounting shaft and located inside the mounting cavity. A second gear that meshes with the third gear is rotatably mounted at the rotatable connection between the first connecting rod and the second connecting rod. A first gear that meshes with the second gear is fixed on the outer wall of the second mounting shaft.

[0012] The interior of the mounting cavity is equipped with a turntable, and the outer wall of the turntable is provided with a sloping groove along the circumferential direction for sliding connection of the top of the first mounting shaft, and the top of the second mounting shaft passes through the center of the outer wall of the turntable.

[0013] A shaft tube is provided at the top center of the turntable, and the top end of the second mounting shaft passes through the inside of the shaft tube. Worm gears are fixed on the outer wall of the shaft tube and the outer wall of the second mounting shaft. A worm is provided inside the mounting cavity to mesh with the two worm gears in sequence.

[0014] One end of the worm gear extends to the outside of the mounting base and is fixed with an internal hexagonal disassembly block.

[0015] The technical effects achieved by this utility model are as follows: This invention, through the cooperation of the first sliding groove and the first slider, limits the first mounting shaft to only radial centrifugal or centripetal movement; when the rotating worm drives the turntable to rotate, the sliding cooperation between the inclined groove and the top of the first mounting shaft can drive multiple first mounting shafts to move synchronously, thereby adjusting the circular diameter formed by the arc-shaped grinding plate on the grinding adjustment seat, so as to adapt it to the inner hole of the roller seat with different inner diameters, without the need to replace the grinding head, which greatly improves the versatility of the equipment.

[0016] When the second mounting shaft is driven to rotate by rotating the worm gear, the first gear drives the third gear to rotate through the second gear, which in turn causes the first mounting shaft to drive the grinding adjustment seat to rotate. This allows for quick switching of arc-shaped grinding plates with different roughnesses to the working position that contacts the inner wall of the hole, meeting the needs of different processes such as rough grinding and fine grinding, and simplifying the operation process.

[0017] The linkage structure between the first and second connecting rods in this invention ensures that the second gear remains engaged with the first and third gears throughout the radial movement of the first mounting shaft, thus guaranteeing transmission stability. Attached Figure Description

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-3 As shown, a roller seat inner hole grinding device includes a worktable 1. A horizontal and vertical moving mechanism 2 is provided on the top of the worktable 1. The horizontal and vertical moving mechanism 2 includes an X-axis linear module and a Y-axis linear module. The X-axis linear module is fixed to the top of the worktable 1. The Y-axis linear module is fixed to the slider of the X-axis linear module. The motor 3 is fixed to the slider of the Y-axis linear module. The output end of the horizontal and vertical moving mechanism 2 is provided with a motor 3. The output shaft of motor 3 is equipped with a grinding head mechanism, which can switch between different roughness arc-shaped grinding plates 10 as needed; A clamping table 5 is provided on the worktable 1 and below the grinding head for clamping the roller seat.

[0022] The grinding head mechanism includes a mounting base 4 located at the output end of the motor 3. The mounting base 4 is a cylindrical structure with an internal mounting cavity.

[0023] At least three first sliding grooves 6 are arranged in a circumferential direction at the bottom of the mounting cavity. A first slider 7 slides inside the first sliding groove 6. A first mounting shaft 8 is rotatably mounted through the outer wall of the first slider 7. A grinding adjustment seat 9 is provided on the outer wall of the first mounting shaft 8 and below the mounting seat 4. The grinding adjustment seat 9 is the main structure. At least three arc-shaped protrusions are arranged in a circumferential direction on the surface of the grinding adjustment seat 9. An arc-shaped grinding plate 10 is assembled on the outer surface of the arc-shaped protrusions. The surface roughness of the multiple arc-shaped grinding plates 10 provided on the grinding adjustment seat 9 is different.

[0024] According to the above structure, the cooperation between the first sliding groove 6 and the first slider 7 makes the movement of the first mounting shaft 8 relatively stable and can also limit the movement of the first mounting shaft 8, so that the first mounting shaft 8 can only move centrifugally or centripetally. In this way, it can be adjusted according to the inner diameter of the inner hole, which improves the flexibility of equipment use. The outer surface of the grinding adjustment seat 9 is equipped with at least three arc-shaped grinding plates 10 with different surface roughness for grinding the inner hole according to different requirements, which further improves the flexibility of equipment use. The arc-shaped protrusion is equipped with arc-shaped grinding plates 10 to avoid the influence of adjacent arc-shaped grinding plates 10, so that the equipment can operate normally.

[0025] like Figures 3-4 As shown, a second connecting rod 15 is rotatably mounted on the outer wall of the first mounting shaft 8 and located within the mounting cavity. A first connecting rod 13 is rotatably mounted on the other end of the second connecting rod 15. A second mounting shaft 11, rotatably connected to the first connecting rod 13, is rotatably mounted at the center of the mounting cavity. A third gear 16 is fixed on the outer wall of the first mounting shaft 8 and located within the mounting cavity. A second gear 14, meshing with the third gear 16, is rotatably mounted at the rotatable connection between the first connecting rod 13 and the second connecting rod 15. A first gear 12, meshing with the second gear 14, is fixed on the outer wall of the second mounting shaft 11. A turntable 17 is rotatably mounted inside the mounting cavity. A sloping groove 18, slidably connected to the top of the first mounting shaft 8, is opened on the outer wall of the turntable 17 along the circumferential direction. The top of the second mounting shaft 11 penetrates the center of the outer wall of the turntable 17.

[0026] According to the above structure, when the turntable 17 is rotated, the turntable 17 drives the inclined groove 18 to rotate. The inclined groove 18 engages with the top end of the first mounting shaft 8, causing the first mounting shaft 8 to move along the first sliding groove 6. The first sliding groove 6 drives the arc-shaped grinding plate 10 on the grinding adjustment seat 9, thereby adjusting the diameter of the circle formed by multiple arc-shaped grinding plates 10 according to the inner diameter of the inner hole to fit the inner hole. When the second mounting shaft 11 rotates, it drives the first gear 12 to rotate, and the first gear 12 drives the second gear 14 to rotate. 14 drives the third gear 16 to rotate, the third gear 16 drives the first mounting shaft 8 to rotate, and the first mounting shaft 8 drives the arc-shaped grinding plate 10 on the grinding adjustment seat 9 to rotate. The arc-shaped grinding plate 10 with the corresponding roughness is adjusted to the inner wall structure of the inner hole. The structure is simple and easy to operate, and it can grind different inner hole diameters and surface roughness. The cooperation between the first connecting rod 13 and the second connecting rod 15 ensures that the second gear 14 can always maintain meshing with the first gear 12 and the third gear 16 when the third gear 16 moves.

[0027] like Figures 3-4 As shown, a shaft tube is provided at the top center of the turntable 17, and the top end of the second mounting shaft 11 passes through the inside of the shaft tube. Worm gears 20 are fixed on the outer wall of the shaft tube and the outer wall of the second mounting shaft 11. A worm 19 is provided inside the mounting cavity, which meshes with the two worm gears 20 in sequence. One end of the worm 19 extends to the outside of the mounting base 4 and is fixed with an internal hexagonal disassembly block.

[0028] According to the above structure, by rotating the internal hexagonal disassembly block with an external hexagonal wrench, the worm gear 19 is rotated, which in turn drives the worm wheel 20 to rotate, and the worm wheel 20 drives the corresponding turntable 17 or the second mounting shaft 11 to rotate. In addition, the worm gear 19 and the worm wheel 20 are designed to have a self-locking mechanism, which prevents the turntable 17 or the second mounting shaft 11 from rotating after adjustment, thus improving the stability of the equipment.

[0029] The working principle of this utility model is as follows: The workpiece to be ground, the roller seat, is placed between the two jaws of the clamping table 5. The drive cylinder is activated to move the jaws to clamp the workpiece, completing the clamping process. The X and Y axis linear modules of the horizontal and vertical moving mechanism 2 are activated, driving the motor 3 and the grinding head mechanism to move, aligning the grinding adjustment seat 9 with the inner hole of the roller seat. A hex wrench is used to rotate the internal hexagonal disassembly block, driving the worm gear 19 to rotate. The worm gear 19 drives the worm wheel 20 on the shaft tube to rotate, thereby causing the turntable 17 to rotate. The inclined groove 18 on the turntable 17 pushes the slider at the top of the first mounting shaft 8, causing the first mounting shaft 8 to move radially along the first sliding groove 6 until the diameter of the circle formed by the three arc-shaped grinding plates 10 matches the inner diameter of the inner hole. At this point, the wrench is stopped, and the worm... The rod 19 and worm gear 20 are self-locked in place. If the grinding roughness needs to be changed, the hex wrench is turned in the opposite direction, causing the worm 19 to drive the worm gear 20 on the second mounting shaft 11 to rotate. The second mounting shaft 11 drives the first gear 12 to rotate, and the first gear 12 drives the third gear 16 and the first mounting shaft 8 to rotate through the second gear 14. This, in turn, drives the grinding adjustment seat 9 to rotate, rotating the arc-shaped grinding plate 10 with the required roughness to the position where it contacts the inner wall of the inner hole. Then, the wrench is stopped. The motor 3 is started, and the motor 3 drives the mounting seat 4 and the grinding adjustment seat 9 to rotate as a whole. The arc-shaped grinding plate 10 contacts the inner wall of the inner hole and performs grinding. At the same time, the grinding head mechanism is slowly moved by the horizontal and vertical moving mechanism 2 to achieve uniform grinding of the entire inner hole wall.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
