Description

Technical Field

[0001] This utility model relates to the field of gear processing equipment technology, specifically a center hole grinding machine for gear processing. Background Technology

[0002] Gears are an indispensable part of mechanical transmission. In the gear manufacturing process, the accuracy of the center hole directly affects the precise assembly of the gear shaft and the accuracy of gear transmission. Since the previous processes such as heat treatment may cause deformation and positional deviation of the center hole, the grinding of the gear center hole is particularly important. It ensures a high-precision machining datum by finely correcting the center hole. Currently, a modified cylindrical grinding machine can be used for grinding. During grinding, the stability of the gear needs to be maintained. However, due to the different specifications of gears, different fixtures are required to fix the gears when machining gears of different sizes, which is quite troublesome. In addition, the gear needs to be manually aligned to the center, and the clamping time for a single piece affects the processing efficiency. To address the above problems, the inventor proposes a center hole grinding machine for gear machining to solve the above problems. Utility Model Content

[0003] To address the current problems of cumbersome grinding of center holes in gears, especially when machining gears of different sizes, requiring manual center alignment and time-consuming single-piece clamping, this invention aims to provide a center hole grinding machine for gear machining.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a center hole grinding machine for gear processing, comprising a lathe body, with convex plates fixedly connected to both sides of the lathe body, a movable seat slidably connected to the top surface of the convex plate, a bracket fixedly connected to the top surface of the movable seat, a fixing component provided on one side of the bracket, the fixing component comprising a cavity, a convex shell fixedly connected to the side wall of the cavity, a through opening provided in the middle of the side wall of the cavity, a gear ring rotatably connected to the inner side wall of the cavity, a motor provided outside the cavity, a transmission gear fixedly connected to the output shaft end of the motor, the transmission gear corresponding to and meshing with the gear ring, a gear plate slidably connected inside the convex shell, the gear plate penetrating through the cavity, and the gear plate slidably connected to the cavity, and corresponding to and meshing with the transmission gear, a clamping plate provided on one side of the gear plate.

[0005] Preferably, the side of the bracket away from the movable seat is fixedly connected to the outer wall of the cavity, and the bracket is offset from the convex shell. The cross-section of the cavity is annular, and the axis of the gear ring coincides with the axis of the cavity. An electric cylinder is provided on one side of the convex plate, and the output shaft end of the electric cylinder is fixedly connected to the end face of the movable seat. A fixed seat is sleeved on the side wall of the electric cylinder, and the fixed seat is fixedly connected to the side wall of the convex plate. When the electric cylinder is activated, the movable seat moves under the action of the output shaft of the electric cylinder, and the fixed component can be moved through the bracket. A base is provided on the side wall of the motor, and the base is fixedly connected to the outer wall of the cavity. The transmission gear... There are six transmission gears, and the six transmission gears are arranged in an array with the axis of the gear ring as the center. All six transmission gears mesh with the gear ring. The motor is installed on the base and must be a self-locking motor. When the motor is started, the transmission gears rotate under the action of the motor output shaft. Through the mutual meshing of the transmission gears and the gear ring, the other five transmission gears can rotate. Through the mutual meshing of the transmission gears and the gear plate, and with the cooperation of the guide groove and the guide block, the gear plate can be translated. Then, the clamping plate can be translated by the convex column to center and clamp the gear placed in the through hole.

[0006] Preferably, the side wall of the clamping plate is fixedly connected with a protruding post, and the side of the protruding post away from the clamping plate is fixedly connected to the end face of the gear plate. The clamping plate is installed and fixed by the protruding post. There are six clamping plates, and the six clamping plates are arranged in an array with the axis of the cavity as the center. It should be noted that the axis of the cavity must coincide with the axis of the grinding head on the lathe body, so that when the gear placed in the through-hole is centered and clamped, the gear can be automatically aligned and the single-piece clamping time can be reduced. The top surface of the gear plate is provided with a guide groove, and the inner side wall of the cavity is fixedly connected with a guide block. The guide block corresponds to the guide groove and is slidably connected. When the gear plate meshes with the transmission gear, the gear plate can move more smoothly through the cooperation of the guide block and the guide groove.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: the fixed components can facilitate the centering and clamping of gears of different specifications within a certain range, so that the axis of the gear corresponds to the grinding head on the lathe body, thereby achieving the purpose of automatically aligning the gear to the center, reducing the clamping time of a single piece and improving production efficiency. Moreover, the gear after centering and clamping can be adjusted laterally to cooperate with the grinding head on the lathe body for grinding the center hole of the gear. Attached Figure Description

[0017] The side of the bracket 6 away from the movable seat 5 is fixedly connected to the outer wall of the cavity 7, and the bracket 6 is offset from the convex shell 8. The cross-section of the cavity 7 is annular, and the axis of the toothed ring 12 coincides with the axis of the cavity 7.

[0018] By adopting the above technical solution, an electric cylinder 3 is provided on one side of the convex plate 2. The output shaft end of the electric cylinder 3 is fixedly connected to the end face of the movable seat 5. A fixed seat 4 is sleeved on the side wall of the electric cylinder 3. The fixed seat 4 is fixedly connected to the side wall of the convex plate 2. When the electric cylinder 3 is started, the movable seat 5 moves under the action of the output shaft of the electric cylinder 3. The fixed component 18 can be driven to move through the bracket 6.

[0019] The motor 9 has a base 10 on its side wall, which is fixedly connected to the outer side wall of the cavity 7. There are six transmission gears 13, which are arranged in an array around the axis of the gear ring 12, and all six transmission gears 13 mesh with the gear ring 12.

[0020] By adopting the above technical solution, the motor 9 is installed on the base 10. The motor 9 needs to be a self-locking motor. When the motor 9 is started, the transmission gear 13 rotates under the action of the output shaft of the motor 9. Through the mutual meshing of the transmission gear 13 and the gear ring 12, the other five transmission gears 13 can rotate. Through the mutual meshing of the transmission gear 13 and the gear plate 14, and with the cooperation of the guide groove 15 and the guide block, the gear plate 14 can be translated.
