[0002] Gears are mechanical parts with tooth grooves that can transmit motion and power through meshing. They are widely used in mechanical transmission systems. In the gear grinding process, a gear grinding clamping coaxiality calibration device is used to ensure accurate calibration of the coaxiality between the gear shaft and the machine tool spindle.

[0003] Existing gear grinding clamping coaxiality calibration devices are inconvenient to fix, inconvenient to apply to different sizes, and inconvenient to improve work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a gear grinding clamping coaxiality calibration device to solve the problem that existing gear grinding clamping coaxiality calibration devices are inconvenient to fix.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a gear grinding clamping coaxiality calibration device, including a base and a limiting component;

[0006] A limiting component is fixed on one side of the top of the base, and a movable structure is fixed on the other side of the top of the base.

[0007] The top of the base is fixed with a rotating structure, and the top of the rotating structure is fixed with a fixing structure.

[0008] The fixed structure includes a fixed frame fixed to the top of the rotating structure. A third electric push rod is fixed to the top of the rotating structure at the bottom of the fixed frame. A movable seat is fixed to the top of the third electric push rod. Hinged rods are evenly fixed to both sides of the movable seat. A slide rail is fixed to the top of the fixed frame. Slide seats are slidably connected to both sides of the top of the slide rail.

[0009] When using this device, the fixed structure enables quick and easy fixing, thereby improving the working efficiency of the gear grinding clamping coaxiality calibration device; the movable structure facilitates calibration, thus improving the convenience of use; and the rotating structure facilitates auxiliary calibration, further enhancing the convenience of use.

[0010] Preferably, the limiting assembly includes a bracket, a first electric push rod, a limiting plate, and a movable plate. The bracket is fixed to the top of the base, and the first electric push rod passes through one side of the top of the bracket. The movable plate is fixed to the bottom end of the first electric push rod, and the bottom end of the movable plate is rotatably connected to the limiting plate. The movable plate drives the limiting plate to press against the top of the workpiece. When the workpiece rotates, it drives the limiting plate to rotate, thereby enhancing the stability of the workpiece during rotation.

[0011] Preferably, the moving structure includes a servo motor, a fixed frame, a movable frame, a threaded rod, a movable seat, a slide rod, a second electric push rod, a support plate, a coaxiality measuring instrument, and guide rods. The fixed frame is fixed to the top of the base. A threaded rod is provided on one side of the top of the fixed frame. The movable seat is threadedly connected to the outer side of the threaded rod. A servo motor is installed on the top of the fixed frame above the threaded rod. A slide rod passes through one side of the interior of the movable seat. One side of the movable seat extends to the outside of the fixed frame and is fixed to the movable frame. A second electric push rod passes through one side of the interior of the movable frame. A support plate is fixed to one end of the second electric push rod. A coaxiality measuring instrument is provided at the bottom of the support plate. Guide rods pass through the interiors of the movable frames on both sides of the second electric push rod. Under the action of the slide rod, the movable seat is prevented from rotating along with the threaded rod. After moving, the movable seat will drive the coaxiality measuring instrument to move up and down through the movable frame.

[0012] Preferably, the top end of the threaded rod passes through the fixed frame and is fixedly connected to the output end of the servo motor. The movable seat and the slide rod form a sliding structure, with both ends of the slide rod fixedly connected to the inner wall of the fixed frame. The guide rod and the movable frame form a sliding structure, with one end of the guide rod fixedly connected to one side of the support plate. Under the action of the guide rod, the stability of the support plate during movement is enhanced. The moved support plate will drive the coaxiality measuring instrument to move back and forth, thereby enabling the coaxiality measuring instrument to accurately reach the position to be tested, thus measuring and calibrating the coaxiality of the gear grinding clamp.

[0013] Preferably, the rotating structure includes a fixed base, a turntable, a rotating shaft, a worm gear, a drive motor, a worm wheel, and an internal cavity. The fixed base is fixed to the top of the base, and the internal cavity is provided inside the fixed base. The worm wheel is disposed inside the internal cavity, and a worm gear is meshed with one side of the worm wheel. The drive motor is mounted on the outer wall of the fixed base at one end of the worm gear. The rotating shaft passes through the interior of the worm wheel, and the top end of the rotating shaft extends to the outside of the fixed base and is fixed to the turntable. Through the meshing connection between the worm gear and the worm wheel, the worm gear drives the worm wheel to rotate when it rotates.

[0014] Preferably, the bottom end of the rotating shaft extends into the interior of the fixed base and forms a rotating structure with the fixed base, while one end of the worm gear extends into the exterior of the fixed base and is fixedly connected to the output end of the drive motor. The worm gear drives the turntable to rotate via the rotating shaft, causing the turntable to rotate the workpiece, thereby adjusting the circumferential position of the workpiece.

[0015] Preferably, a movable plate is fixed to the top of each slide block, and a clamping plate is fixed to the top of each movable plate. When the movable seat moves up and down, the movable seat will drive the movable plate to move in the opposite direction through the hinge rod. Under the action of the slide rail and the slide block, the stability of the movable plate during movement is enhanced.

[0016] Preferably, the bottom end of the fixed frame is fixedly connected to the top end of the turntable, the bottom end of the third electric push rod is fixedly connected to the top end of the turntable, the end of the hinge rod away from the movable seat is hinged to one side of the moving plate, and rubber pads are fixed to both ends of the top side of the clamping plate. The moving plate, after being moved, will cause the clamping plate to move closer to or further away. Under the action of the rubber pads, the friction between the clamping plate and the workpiece is increased, thereby enabling the fixing of workpieces of different sizes.

[0017] The gear grinding clamping coaxiality calibration device provided by this utility model has the following advantages:

[0018] With a fixed structure, when the movable seat moves up and down, the movable seat will drive the moving plate to move in the opposite direction through the hinge rod. Under the action of the slide rail and slide block, the stability of the moving plate during movement is enhanced. After moving, the moving plate will drive the clamping plate to move closer or further away. Under the action of the rubber pad, the friction between the clamping plate and the workpiece is increased, so that workpieces of different sizes can be fixed. This realizes the function of quick and easy fixing of the device, thereby improving the working efficiency of the gear grinding clamping coaxiality calibration device during use.

[0019] By incorporating a movable structure, the sliding rod prevents the movable seat from rotating along with the threaded rod. After moving, the movable seat drives the coaxiality measuring instrument up and down via the movable frame. The guide rod enhances the stability of the support plate during movement. The moved support plate then drives the coaxiality measuring instrument back and forth, allowing it to accurately reach the position to be tested. This enables the measurement and calibration of the coaxiality of the gear grinding clamp, facilitating calibration and improving the ease of use of the gear grinding clamp coaxiality calibration device.

[0020] By incorporating a rotating structure and connecting a worm gear and a worm wheel, the worm gear rotates, which in turn drives the worm wheel to rotate. The worm wheel then drives the turntable to rotate via a rotating shaft, causing the turntable to rotate the workpiece. This allows for adjustment of the workpiece's circumferential position, enabling the device to facilitate auxiliary calibration and improving the ease of use of the gear grinding clamping coaxiality calibration device.
