Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a gear grinding device that is easy to fix. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through the continuous meshing of teeth. Due to the smoothness of gear transmission, it is widely used in mechanical transmission and the entire mechanical field. Gears can be divided into four categories, including cylindrical gears, bevel gears, ring gears, and special purpose gears.

[0003] If the gear grinding device needs to be fixed by multiple sets of bolts, nuts or complex clamps, the operator needs to repeatedly adjust the position and tightness of multiple components, which not only increases the difficulty of operation, but also prolongs the preparation time. When fixing the gear, manual visual alignment is required, which is prone to positioning deviation. If the coaxiality error between the gear center and the grinding spindle is too large, the gear tooth profile accuracy after grinding will not meet the standard. Utility Model Content

The mounting grooves 12 are arranged in a circular array on the outer surface of the fixing column 20 so that the three rotating rods 14 can evenly fix the gear. The connecting blocks 15 are located on the upper part of the side wall of the rotating rod 14 to optimize the lever arm length and improve the adjustment efficiency of the adjusting hydraulic pump 18. The auxiliary components are located on the upper surface of the base 1. The auxiliary components include the first lifting hydraulic pump 2, the first lifting hydraulic rod 3, the grinding motor 4, the grinding rotating column 5, the grinding wheel 6, the controller 7, the support plate 8, the mounting plate 9, and the rotating... The drive motor 21, drive rotating column 22, and gear adapter column 23 work together to complete the grinding and rotation of the gear. The drive motor 21 is connected to the upper surface of the base 1 and is fixed to the base 1 by bolts, providing a power source for the rotation of the gear. The output end of the drive motor 21 is fixedly connected to the gear adapter column 23, which is used to install the gear to be ground and rotates synchronously with the drive motor 21. The drive motor 21 has two first lifting hydraulic pumps 2 on its left and right sides, which are symmetrically distributed to ensure the stability of the grinding process. The output end of the first lifting hydraulic pump 2 is fixedly connected to the first lifting hydraulic rod 3, which drives the grinding. Motor 4 enables vertical position adjustment.

The size of the gear adapter column 23 is matched with the size of the rotating rod 14 to ensure that the rotating rod 14 can stably fix gears of different specifications.

[0025] Working principle: First, the gear to be ground is installed on the gear adapter post 23. The system is started via controller 7, initializing each hydraulic pump and motor. The second lifting hydraulic pump 10 is started, driving the second lifting hydraulic rod 11 to descend, bringing the fixed post 20 close to the gear on the gear adapter post 23. Simultaneously, the three adjusting hydraulic pumps 18 are started, and the adjusting hydraulic rod 17 extends, pushing the rotating rod 14 around the positioning post 13 through the connecting post 16 and connecting block 15 until the lower end of the rotating rod 14 contacts the outer edge of the gear and forms a stable three-point fixation. According to the height of the gear, the first lifting hydraulic pump 2 is adjusted via controller 7, causing the first lifting hydraulic rod 3 to drive the grinding motor 4 and grinding wheel 6 to descend to the appropriate grinding height, ensuring that the position of the grinding wheel 6 is precisely aligned with the tooth surface of the gear. The grinding motor 4 drives the grinding rotating column 5 and the grinding wheel 6 to rotate at high speed. At the same time, the rotating motor 21 is started, which drives the gear adapter column 23 and the gear to rotate slowly, so that the grinding wheel 6 grinds each tooth surface of the gear evenly. The controller 7 monitors various parameters in real time during the grinding process, such as hydraulic system pressure and motor speed. According to the grinding effect, the position of the first lifting hydraulic pump 2 or the second lifting hydraulic pump 10 is finely adjusted in time to ensure grinding accuracy. After the grinding operation is completed, the rotating motor 21 and the grinding motor 4 are stopped in sequence, the adjusting hydraulic pump 18 is started, the adjusting hydraulic rod 17 is retracted, the rotating rod 14 is driven to release the gear, the second lifting hydraulic pump 10 is started, and the fixed column 20 is raised to the initial position. Finally, the ground gear is removed from the gear adapter column 23.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
