Description

Technical Field

[0002] In the field of machinery manufacturing, gears are key components, and their machining accuracy directly affects the performance and reliability of mechanical equipment. Grinding, as a finishing process, plays an important role in gear manufacturing, achieving high precision with minimal machining and is widely used in the machinery manufacturing industry.

[0003] Traditional gear grinding equipment has many limitations. On the one hand, the equipment is difficult to adjust in terms of angle, which often requires multiple clamping during gear processing. This not only reduces production efficiency but may also introduce errors due to repeated clamping, affecting the gear processing accuracy. For example, when processing gears with complex shapes, existing equipment cannot flexibly adjust the grinding angle, failing to meet the precise grinding requirements of different parts of the gear.

[0004] On the other hand, some existing grinding equipment lacks versatility. Taking the grinding equipment for automotive gears disclosed in Chinese utility model patent CN 219725625 U as an example, while it solves the problem of inconvenient angle adjustment to some extent, it is only suitable for grinding specific types of gears. When dealing with thicker gears or bevel gears, the grinding operation of this equipment becomes cumbersome and even difficult to complete, greatly limiting its application in diverse gear processing scenarios. At the same time, some equipment lacks stability during the grinding process, easily leading to unstable grinding quality and failing to meet the requirements of high-precision gear processing.

[0005] With the increasing demands for gear precision and diversification in the machinery manufacturing industry, it is of great practical significance to develop a gear processing and grinding equipment that is structurally simple, has low production costs, is easy to install, and has complete functions.

[0026] Among them, motor 4 21 is a servo motor or a stepper motor; motor 2 6 and motor 3 12 are both servo motors or stepper motors; guide groove 1 8 and guide groove 2 10 are both T-shaped guide grooves.

[0027] The utility model is used as follows: It features a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, the gear to be processed is first clamped inside the transmission shaft 26. Then, the extension of the hydraulic cylinder 211 drives the sleeve body 27 to move downwards, clamping the transmission shaft 26 and pressing down on the top of the gear to be processed to complete the clamping. Then, the motor 21 (either a servo motor or a stepper motor) is started. Its output shaft drives the rotating seat 23 to rotate inside the upper left side of the base 1. The thrust ball bearing 24 between the lower stepped surface of the rotating seat 23 and the upper left side of the base 1 reduces rotational resistance. The rotating seat 23 drives the transmission shaft 26 to rotate, and the transmission shaft 26, in conjunction with the sleeve body 27, drives the gear to be processed to rotate. The gear is rotated to the required angle. Then, based on the position and size of the gear to be processed, motors 3 (12) and 2 (6) are started. Here, motor 3 (12) is a servo motor or stepper motor, and its output shaft drives screw 2 (11) to rotate in the center of guide groove 2 (10). Since the threaded hole on the lower side of movable seat 13 is connected to screw 2 (11), and the lower side of movable seat 13 is laterally movably connected to the inside of guide groove 2 (10 is a T-shaped guide groove), the rotation of screw 2 (11) drives movable seat 13 to move laterally within guide groove 2 (10), adjusting the lateral position of movable seat 13. Motor 2 (6) is also a servo motor or stepper motor, and its output shaft drives screw 1 (9) to rotate in the center of guide groove 1 (8). The right side of lifting seat 5 is vertically movably connected to guide groove 1 (8). Inside (guide groove 8 is a T-shaped guide groove), and the threaded hole on the right side of the lifting seat 5 is connected to the screw 9. The rotation of the screw 9 drives the lifting seat 5 to move vertically within the guide groove 8, adjusting the vertical position of the grinding wheel 3 so that it is close to the gear to be processed. During gear grinding, the motor 4 is started, and the motor 4 drives the grinding wheel 3 to rotate at high speed inside the left side of the lifting seat 5. Then, through the linkage of the motor 6 and the motor 12, the rotating grinding wheel 3 is driven to move horizontally and vertically, thus meeting the needs of different gear grinding. In addition, the motor 21 can meet the needs of grinding different teeth around the gear. The locking mechanism 22 can push the locking block 223 through the cylinder 222. Cylinder 226 pushes locking block 225, causing locking block 1 223 and locking block 225 to move towards brake sleeve 227, compressing spring 224. Brake sleeve 227 is fixedly connected to the lower outside of rotating seat 23. As locking block 1 223 and locking block 225 are in close contact with brake sleeve 227, rotating seat 23 is kept locked during grinding, ensuring the reliability and stability of gear grinding. After grinding, cylinder 211 is activated. The piston rod end of cylinder 211 drives connecting seat 210 and connecting shaft 29 to move upward, separating sleeve body 27 from transmission shaft 26, making it easier to remove the finished gear and improving usability.
