Description
Technical Field
[0001] This utility model relates to the field of gear manufacturing technology, and in particular to a gear tooth grinding device for gear manufacturing. Background Technology
[0002] As a core component of mechanical transmission systems, gears achieve precise transmission of motion and power through continuous meshing of evenly distributed teeth on their rims. However, during the machining process of gear teeth, metal burrs often form at the junction of the bottom and sidewalls of the tooth groove due to the working mechanism of the cutting tool and the plastic deformation of the material. These microscopic burrs not only compromise the geometric accuracy of the gear meshing interface but also cause localized stress concentration during high-speed operation, leading to increased transmission noise, intensified vibration, and even early failure modes such as pitting on the tooth surface. To ensure the transmission performance and service life of gears, a specialized tooth groove grinding process must be used to precisely finish the machined gears and remove residual burrs from the tooth grooves.
[0003] For example, the gear grinding device for gear manufacturing disclosed in the utility model with authorization announcement number CN222289608U has the following working principle: "First, the gear to be processed is fitted onto the outside of the gear fixing shaft. The gear fixing shaft is installed above the gear fixing table. The four corner edges of the gear fixing table are connected to connecting blocks. One side of the connecting blocks is connected to the mounting shell. A slider is installed inside the mounting shell. One side of the slider is connected to an electric push rod. The electric push rod drive component is installed inside the drive shell. When the electric push rod is opened, it drives the slider to move inside the mounting shell. The moving mounting shell carries the upper support seat. The support seat carries the fixing frame. The fixing frame carries the clamping pad. The clamping pad and the fixing frame are moved and connected to the gear..." The edge of the gear tooth groove is used to fix the gear. A connecting shell is then installed above the base, and an auxiliary seat is installed inside the connecting shell. One side of the auxiliary seat is connected to an auxiliary push rod. Opening the auxiliary push rod drives the auxiliary seat to move within the connecting shell. The auxiliary seat moves a screw rod, and two sets of nuts are provided on the outer surface of the screw rod. The nuts clamp the mounting sleeve between them. The mounting sleeve carries an auxiliary block, which moves and adjusts to be connected above the gear, further securing the gear. An adjusting seat is installed side-by-side on one side of the gear fixing platform, and a drive box is installed above the adjusting seat. The drive box is connected to a grinding roller, which is used for grinding the edges of the gear tooth grooves. However, since the grinding roller can only perform edge grinding on one gear tooth groove at a time, the grinding efficiency of this process is relatively low when grinding all tooth grooves of the entire gear. Furthermore, this device uses an external clamping method to fix the gear. When it's necessary to change the tooth groove for edge grinding, the operation process is quite cumbersome: first, the current clamping state must be released; then, the gear must be precisely rotated to ensure the grinding roller accurately aligns with the new tooth groove to be ground; finally, the clamping and fixing must be completed again after rotation. This series of complex operations further reduces the overall edge grinding efficiency. Utility Model Content

[0005] As an improvement to the above technical solution, the clamping mechanism includes a clamping platform, a fixed sleeve, a threaded rod, a lifting block, a hinge plate, and an inner clamping body. The clamping platform is installed on the upper end of the rotating platform. The surface of the clamping platform has multiple sliding grooves. The fixed sleeve is fixedly connected to the surface of the clamping platform. The surface of the fixed sleeve has multiple openings. The upper end of the fixed sleeve is threadedly connected to a threaded rod that passes through it. The lower end of the threaded rod is rotatably connected to a lifting block. The surface of the lifting block is hinged to multiple hinge plates. The hinge plates have through openings. The lower end of the hinge plates is hinged to an inner clamping body. The inner clamping body is slidably connected to the sliding grooves.
[0006] As an improvement to the above technical solution, the clamping mechanism further includes a limiting disk and a rotating handle. The limiting disk is threadedly connected to the surface of the fixed sleeve, and the rotating handle is rotatably provided on the surface of the limiting disk.
[0007] As an improvement to the above technical solution, the inner clamping body includes a slider, a moving block, and an inner clamping rod. The slider is slidably connected inside the first slide groove. The upper end of the slider is fixedly connected to a moving block that is hinged to a hinge plate. One end of the moving block is fixedly connected to an inner clamping rod. The clamping surface of the inner clamping rod is provided with an anti-slip rubber pad on one side.
[0008] As an improvement to the above technical solution, the edge grinding mechanism includes a telescopic rod, a lifting frame, a sliding plate, a toothed grinding strip, and a push rod. The lower end of the edge grinding table is equipped with a telescopic rod, and the lower end of the telescopic rod is equipped with a lifting frame.

This allows the grinding work to proceed more smoothly and continuously, thereby significantly improving the overall grinding efficiency of the gear and providing a strong guarantee for high-quality and high-efficiency gear manufacturing.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0020] Please see Figure 1-6This utility model provides a technical solution: a gear tooth groove grinding device for gear manufacturing, including a grinding table 1, a plurality of through holes 2 on the surface of the grinding table 1, a rotating table 3 mounted on the surface of the grinding table 1, a clamping mechanism 4 mounted on the upper end of the rotating table 3, and a grinding mechanism 5 mounted on the lower end of the grinding table 1. The grinding mechanism 5 has a plurality of grinding ends, and the grinding ends of the grinding mechanism 5 pass through the through holes 2.
[0021] In this implementation scheme, when the user starts the gear grinding operation, the gear must first be placed stably on the surface of the clamping mechanism 4. At this time, the position of the gear must be precisely adjusted to ensure that the clamping end of the clamping mechanism 4 can smoothly penetrate the inner circle of the gear. Then, the user slowly rotates the rotating end of the clamping mechanism 4, which will cause the multiple clamping parts of the clamping mechanism 4 to expand in an orderly manner, gradually opening and tightly fitting the inner circle surface of the gear, realizing a stable inner clamping of the gear, completing the reliable fixation of the gear, and laying a solid foundation for the subsequent grinding operation.
[0022] After the gear is fixed, the user activates the grinding mechanism 5. Upon activation, the multiple grinding parts of the mechanism 5 rapidly retract, precisely moving towards the inside of the gear's tooth grooves until they are fully engaged, preparing for grinding. Subsequently, the user operates the mechanism again, activating the lifting mechanism 5. This lifting mechanism drives the multiple grinding parts to reciprocate upwards and downwards. This rhythmic up-and-down movement allows for efficient grinding of multiple tooth grooves on the gear simultaneously.
[0023] When it is necessary to change the tooth groove for grinding, firstly, the multiple grinding parts of the edge grinding mechanism 5 expand to allow the grinding parts to smoothly detach from the current tooth groove. Next, the user starts the rotating table 3, which drives the clamping mechanism 4 and the gear to rotate smoothly together. During the rotation, the user needs to observe closely to ensure that the multiple grinding parts of the edge grinding mechanism 5 can accurately correspond to the new tooth groove. After the position is adjusted, the multiple grinding parts of the edge grinding mechanism 5 retract again and accurately enter the new tooth groove of the gear. Finally, the user starts the lifting part of the edge grinding mechanism 5 again, which drives the multiple grinding parts to perform reciprocating lifting motion to continue grinding the new tooth grooves. Through this operation process, the edge grinding efficiency of the entire gear can be significantly improved, making the edge grinding work more continuous and smooth.
[0024] like Figure 3 , Figure 4 as well as Figure 5As shown, the clamping mechanism 4 includes a clamping platform 41, a fixed sleeve 43, a threaded rod 44, a lifting block 45, a hinge plate 46, and an inner clamping body 47. The clamping platform 41 is installed on the upper end of the rotating platform 3. Multiple sliding grooves 42 are opened on the surface of the clamping platform 41. The fixed sleeve 43 is fixedly connected to the surface of the clamping platform 41. Multiple openings are opened on the surface of the fixed sleeve 43. The upper end of the fixed sleeve 43 is threadedly connected to the threaded rod 44 that passes through it. The lower end of the threaded rod 44 is rotatably connected to the lifting block 45. Multiple hinge plates 46 are hinged to the surface of the lifting block 45. The hinge plates 46 pass through the openings. The lower end of the hinge plates 46 is hinged to the inner clamping body 47. The inner clamping body 47 is slidably connected to the sliding grooves 42.
[0025] In this embodiment, when the gear is located on the surface of the clamping table 41, the user rotates the threaded rod 44, thereby causing the lifting block 45 to move downward. Then, through multiple hinge plates 46, multiple inner clamping bodies 47 slide inside the slide groove 42, and the whole thing expands, thereby using multiple inner clamping bodies 47 to clamp and fix the gear.
[0026] like Figure 3 and Figure 4 As shown, the clamping mechanism 4 also includes a limiting disk 48 and a rotating handle 49. The surface of the fixed sleeve 43 is threadedly connected to the limiting disk 48, and the surface of the limiting disk 48 is rotatably provided with the rotating handle 49.
[0027] In this embodiment, after the inner clamping is completed, the user puts the limiting plate 48 on the upper end of the fixed sleeve 43, and then rotates the rotating handle 49 so that the rotating handle 49 is threadedly connected to the surface of the fixed sleeve 43, and the limiting plate 48 moves down, thereby cooperating with the clamping table 41 to clamp the gear from top to bottom, so as to improve the clamping effect of the clamping mechanism 4 on the gear.
[0028] like Figure 5 As shown, the inner clamping body 47 includes a slider 471, a moving block 472, and an inner clamping rod 473. The slider 471 is slidably connected inside the slide groove 42. The upper end of the slider 471 is fixedly connected to the moving block 472, which is hinged to the hinge plate 46. One end of the moving block 472 is fixedly connected to the inner clamping rod 473. The clamping surface of the inner clamping rod 473 is provided with an anti-slip rubber pad on one side.
[0029] In this embodiment, after the user rotates the threaded rod 44, multiple hinge plates 46 are used to drive multiple sliders 471 to slide inside the slide groove 42, thereby driving multiple moving blocks 472 to expand, and then driving multiple inner clamping rods 473 to clamp and fix the gear.
[0030] like Figure 6As shown, the edge grinding mechanism 5 includes a telescopic rod 51, a lifting frame 52, a sliding plate 54, a toothed grinding strip 55, and a push rod 56. The telescopic rod 51 is installed at the lower end of the edge grinding table 1, and the lifting frame 52 is installed at the lower end of the telescopic rod 51. Multiple sliding grooves 53 are opened on the surface of the lifting frame 52, and multiple push rods 56 are installed on the surface of the lifting frame 52. The sliding plate 54 is slidably connected inside the sliding groove 53. The sliding plate 54 passes through the through opening 2, and the toothed grinding strip 55 is installed on the surface of the sliding plate 54. One end of the push rod 56 is connected to the sliding plate 54.
[0031] In this embodiment, the telescopic rod 51 can drive multiple sliding plates 54 to reciprocate up and down through the lifting frame 52. The sliding plates 54 use the tooth grinding strips 55 installed on their surfaces to grind the tooth grooves of the gears. At the same time, the push rod 56 can drive the sliding plates 54 to slide inside the second groove 53, thereby causing the multiple sliding plates 54 to expand or retract. This gives the edge grinding mechanism 5 strong adaptability, allowing it to flexibly adjust the grinding range according to gears of different radii, and also provides the prerequisite for groove changing grinding work.
[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
