DETAILED DESCRIPTION
[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] like Figures 1 to 4As shown, an automobile ring gear grinding tool includes a support platform 101, a placement plate 102 is provided on the support platform 101, a fixing plate 202 is provided on the placement plate 102, an adjustment mechanism 200 is provided on the fixing plate 202 for fixing the ring gear body 103 with shaft holes of different sizes, and a clamping mechanism 300 is provided on the adjustment mechanism 200 to prevent the ring gear body 103 from jumping during the grinding process.
[0019] When the gear ring body 103 needs to be ground, the gear ring body 103 is fixed on the placement plate 102 using the adjustment mechanism 200 according to the different sizes of the axial holes of the gear ring body 103, and the gear ring body 103 is clamped by the clamping mechanism 300 to avoid the ring gear body 103 from jumping during the grinding process, which affects the grinding effect.
[0020] In this embodiment, the adjustment mechanism 200 includes a groove 205 provided on the fixed plate 202, a gear 206 is rotatably provided in the groove 205, a plurality of movable grooves 204 connected to the groove 205 are provided on the fixed plate 202, a rack 209 is movably provided in the movable groove 204, the rack 209 is meshed with the gear 206, a cover plate 203 is provided on the fixed plate 202, a motor 201 is fixed on the cover plate 203, and the working end of the motor 201 is transmission-connected to the gear 206.
[0021] The motor 201 is used to drive the gear 206 to rotate, and the gear 206 is meshed with the rack 209 to drive the rack 209 to move. According to the different sizes of the shaft holes of the ring gear body 103, the spacing between the racks 209 is adjusted to accommodate more specifications of the ring gear body 103, expand the scope of application of the gear grinding tooling, and enhance the practicality and flexibility of the gear grinding tooling.
[0022] In this embodiment, a guide groove 207 is formed on the inner wall of the movable groove 204 , a slider 208 is slidably fitted in the guide groove 207 , and the side wall of the slider 208 is fixedly connected to the side wall of the rack 209 .
[0023] When the rack 209 moves, it drives the slider 208 to move in the guide groove 207, so that the rack 209 moves more smoothly, thereby improving the stability and reliability of the gear grinding tooling.
[0024] In this embodiment, the clamping mechanism 300 includes a mounting block 301 fixed on the rack 209, and a mounting groove is provided on the mounting block 301. A driving gear 305 is provided in the mounting groove and rotated by a rotating shaft. A clamping block 302 is sleeved on the rotating shaft, and the driving gear 305 is meshed with a movable rack 303. The movable rack 303 is provided on the mounting block 301 through a through hole, and a spring 304 is provided between the side wall of the movable rack 303 and the side wall of the mounting block 301.
[0025] When the rack 209 approaches the gear ring body 103, the movable rack 303 abuts against the gear ring body 103. As the rack 209 moves, the movable rack 303 is squeezed, so that the movable rack 303 moves in the through hole in the direction away from the gear ring body 103. The meshing connection between the movable rack 303 and the driving gear 305 drives the driving gear 305 to rotate, and then drives the clamping block 302 to rotate, so that the clamping block 302 is pressed down and abuts against the surface of the gear ring body 103, thereby avoiding the significant shaking of the gear ring body 103 caused by the grinding force during the gear grinding process, and the occurrence of uncontrolled jumping, thereby enhancing the stability of the gear grinding tooling and improving the gear grinding quality.
[0026] In this embodiment, a plurality of leakage holes 104 are provided on the placement plate 102 , and a receiving seat 100 is provided at the bottom of the support platform 101 .
[0027] When the gear ring body 103 is being ground, the debris generated by the grinding falls into the receiving seat 100 through the leakage hole 104, which is convenient for the centralized collection of the debris, facilitates the subsequent cleaning operation of the staff, and improves the convenience of the gear grinding tool.
[0028] Working process and principle: When the device is in use, the motor 201 is used to drive the gear 206 to rotate, and the gear 206 is meshed with the rack 209 to drive the rack 209 to move. According to the different sizes of the shaft holes of the ring gear body 103, the spacing between the racks 209 is adjusted, and the ring gear body 103 is fixed on the placement plate 102 to adapt to more specifications of the ring gear body 103, expand the scope of application of the gear grinding tooling, and enhance the practicality and flexibility of the gear grinding tooling. When the rack 209 approaches the ring gear body 103, the mobile rack 303 abuts against the ring gear body 103. As the rack 209 moves, the mobile rack 303 is squeezed, so that the mobile rack 303 moves in the through hole. The gear ring 103 is moved away from the gear ring body 103, and the driving gear 305 is driven to rotate by moving the rack 303 and meshing with the driving gear 305, thereby driving the clamping block 302 to rotate, so that the clamping block 302 is pressed down and abuts against the surface of the gear ring body 103, thereby avoiding the significant shaking of the gear ring body 103 caused by the grinding force during the grinding process, and the occurrence of uncontrolled jumping, thereby enhancing the stability of the gear grinding tooling and improving the gear grinding quality. After the gear ring body 103 is fixed, it is subjected to gear grinding. The debris generated by grinding falls into the receiving seat 100 through the leak hole 104, which is convenient for the centralized collection of the debris, facilitates the subsequent cleaning operation of the staff, and improves the convenience of the gear grinding tooling.
