Description

Technical Field

[0001] The utility model relates to the technical field of gear side grinding, in particular to a gear side grinding device. Background Technique

[0002] After the hollow gear is cut, in order to facilitate subsequent polishing work, it is necessary to first roughly grind the outer surface of the side of the hollow gear to grind off the iron filings and obvious burrs on the surface of the hollow gear, preventing the iron filings from adhering to the surface of the hollow gear and scratching the gear during subsequent grinding, thereby reducing the accuracy of the hollow gear;

[0003] When grinding the hollow gear, the user needs to make different adjustments according to the inner diameter and thickness of the grinding gear so that the brush can fully contact the four sides of the gear for grinding. However, the traditional grinding machine cannot be adjusted according to the inner diameter and thickness of the hollow gear itself. Therefore, the surface of the hollow gear cannot fully contact the grinding brush, and thus the grinding brush cannot fully grind the side surface of the hollow gear, making it easy for iron filings to remain on the gear surface, resulting in the iron filings scratching the outer surface of the gear during subsequent polishing;

[0004] In view of the above situation, we propose a gear side grinding device. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a gear side grinding device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A gear side grinding device includes a workbench. A bracket is fixedly connected to the bottom of the workbench. A fixed rod is rotatably connected through the interior of the workbench. A movable rod is slidably connected inside the fixed rod. A positioning disk is fixedly connected to the top of the movable rod. Moving grooves are evenly arranged at intervals on the positioning disk. A lead screw is rotatably connected to the inner wall of the moving groove. A limiting block threaded through by the lead screw is slidably connected inside the moving groove.

[0008] A conversion component is arranged at the center of the four groups of lead screws. The output end of the conversion component is fixedly connected to one end of the lead screw passing through the positioning disk. The input end of the conversion component is fixedly connected to a connecting rod rotatably connected inside the positioning disk. A jack is opened inside the top of the connecting rod.

[0009] One side of the top of the fixed rod is fixedly connected with a fixed frame. The internal space of the fixed frame is communicated with the fixed rod. A fixed block is slidably connected inside the fixed frame. One side outer surface of the fixed block away from the movable rod is rotatably connected with a screw rod. The screw rod penetrates through the fixed frame and is threadedly connected with the fixed frame.

[0010] Preferably, an installation frame is fixedly connected to the inner wall of the bracket. A second driving motor is fixedly connected to the top of the installation frame. The output end of the second driving motor is fixedly connected to the outer surface of one end of the fixed rod penetrating through the workbench.

[0011] Preferably, limiting frames are fixedly connected to both sides of the positioning disk on the top of the workbench. A moving frame is slidably connected inside the limiting frames. A first driving motor is fixedly connected to one side of the moving frame facing the positioning disk. The output end of the first driving motor is fixedly connected to a grinding disk.

[0012] Preferably, a hydraulic cylinder is fixedly connected to the outer surface of the workbench below the limiting frames. The output end of the hydraulic cylinder is fixedly connected to the bottom outer surface of the moving frame.

[0013] Preferably, the outer surface of the limiting block has a moving arc that can fit with the inner wall of the gear.

[0014] Preferably, a brush with a certain hardness is fixedly connected around the grinding disk.

[0015] For a gear side grinding device proposed by the present utility model, the beneficial effects are as follows: When positioning the hollow gear, the user inserts a tool into the jack above the connecting rod and rotates it, so that the limiting block can move outwards and abut against the inner wall of the hollow gear. The limiting block can be adjusted according to the inner diameter of the hollow gear, so that the hollow gear will not shift during grinding. During the grinding process, the position of the movable rod can also be adjusted, so that the position of the hollow gear is within the vertical movement range of the grinding disk, so that the outer surface of the hollow gear can be completely ground by the grinding disk, so that the iron filings on the surface of the hollow gear can be fully cleaned, so that the probability of the iron filings scratching the hollow gear is reduced, and thus the surface of the hollow gear is smoother.

[0023] Referring to FIGS. 1-4, a gear side grinding device includes a workbench 1. A bracket 2 is fixedly connected to the bottom of the workbench 1. An installation frame 8 is fixedly connected to the inner wall of the bracket 2. A second driving motor 9 is fixedly connected to the top of the installation frame 8. The output end of the second driving motor 9 is fixedly connected to the outer surface of one end of a fixed rod 10 passing through the workbench 1. Limit frames 3 are fixedly connected to both sides of the positioning disc 12 on the top of the workbench 1. A moving frame 4 is slidably connected to the inside of the limit frames 3. A first driving motor 6 is fixedly connected to the side of the moving frame 4 facing the positioning disc 12. The output end of the first driving motor 6 is fixedly connected to a grinding disc 7. A brush with a certain hardness is fixedly connected to the periphery of the grinding disc 7. A hydraulic cylinder 5 is fixedly connected to the outer surface of the workbench 1 below the limit frames 3. The output end of the hydraulic cylinder 5 is fixedly connected to the bottom outer surface of the moving frame 4. When positioning a hollow gear, the hydraulic cylinder 5 drives the first driving motor 6 to move upward, so that the grinding disc 7 at the output end of the first driving motor 6 does not interfere with the user's positioning of the hollow gear.

[0024] A fixed rod 10 is rotatably connected through the inside of the workbench 1. An active rod 11 is slidably connected inside the fixed rod 10. A positioning disk 12 is fixedly connected to the top of the active rod 11. Moving grooves 13 are evenly arranged at intervals on the positioning disk 12. A lead screw 15 is rotatably connected to the inner wall of the moving groove 13. A limiting block 17 threaded through by the lead screw 15 is slidably connected inside the moving groove 13. The outer surface of the limiting block 17 has a moving arc that can fit with the inner wall of the gear; a conversion assembly 14 is arranged at the center of the four lead screws 15. The output end of the conversion assembly 14 is fixedly connected to one end of the lead screw 15 passing through the positioning disk 12. The input end of the conversion assembly 14 is fixedly connected to a connecting rod 16 rotatably connected inside the positioning disk 12. A jack is opened inside the top of the connecting rod 16. The user inserts a tool into the inside of the jack and rotates it, thereby driving the limiting block 17 to move and abut against the inner wall of the hollow gear, achieving the purpose of positioning the hollow gear.

[0025] One side of the top of the fixed rod 10 is fixedly connected to a fixed frame 18. The internal space of the fixed frame 18 is communicated with the fixed rod 10. A fixed block 19 is slidably connected inside the fixed frame 18. The outer surface of one side of the fixed block 19 away from the active rod 11 is rotatably connected to a screw rod 20. The screw rod 20 passes through the fixed frame 18 and is threadedly connected to the fixed frame 18. The user rotates the screw rod 20 to drive the fixed block 19 to move, thereby enabling the active rod 11 to move inside the fixed rod 10.

[0026] In summary: During the application of the present utility model, when positioning the hollow gear, the user first adjusts the limiting block 17 to the minimum limit value, then places the hollow gear above the positioning disk 12 and keeps the center of the hollow gear coincident with the center of the positioning disk 12. Then the user inserts a tool into the jack above the connecting rod 16 and rotates it. After being converted by the conversion assembly 14, the lead screw 15 is driven to rotate, thereby driving the limiting block 17 to move outward inside the moving groove 13 until the bottom of the four limiting blocks 17 abuts against the inner wall of the hollow gear, thereby achieving the purpose of limiting the hollow gear. Then the user rotates the screw rod 20 to drive the fixed block 19 to move inside the fixed frame 18, thereby enabling the active rod 11 to move inside the fixed rod 10. The user moves the active rod 11 so that the outer wall of the hollow gear above the positioning disk 12 is within the movable range of the grinding disk 7, thereby enabling the outer surface of the hollow gear to be fully ground;

[0027] When grinding the hollow gear, the user first starts the hydraulic cylinder 5 to drive the moving frame 4 to move downward, thereby driving the first drive motor 6 to drive the grinding disk 7 to move downward, so that the brush edge of the grinding disk 7 fits with the edge of the hollow gear. Finally, the machine is started, and the first drive motor 6 and the second drive motor 9 are driven, so that while the hollow gear rotates self - rotatably, the grinding disk 7 rotates to grind the edge of the hollow gear.

[0028] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
