Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a gear surface treatment device for gear processing. Background Technology

[0002] Currently, gears require surface grinding during the manufacturing process. Most existing gear surface treatment devices can only grind the end face and cannot grind the tooth grooves between the teeth at the same time, which is inconvenient to use.

[0003] To address the aforementioned issues, existing technology CN221560697U provides a gear surface treatment device for high-speed precision gear machining, comprising a work box, a fixed block fixedly connected to the inner wall of the work box, a worktable provided at the upper end of the fixed block, a fixed column fixedly connected to the upper end face of the worktable, and two hydraulic telescopic rods symmetrically fixedly connected to the side wall of the fixed column, with an arc-shaped plate fixedly connected to the telescopic end of each hydraulic telescopic rod. This invention uses an electric telescopic rod and a fixed frame to drive a grinding block to press against the gear groove. A hydraulic cylinder and a connecting block drive a grinding disc to move downwards and press against the gear to be processed. A drive motor and a rotating shaft drive the grinding block to rotate, allowing the grinding block to grind the gear groove. A servo motor and a grinding disc can grind the end face of the gear to be processed. Therefore, both the end face and the gear groove can be ground simultaneously, making it more convenient to use.

[0004] However, in the aforementioned prior art, errors are prone to occur when clamping the gear by driving the two arc-shaped plates with two hydraulic telescopic rods, resulting in the inability to position and clamp the gear, thus affecting the machining accuracy. Utility Model Content

[0005] The purpose of this utility model is to provide a gear surface treatment device for gear processing, which solves the technical problem in the prior art that errors easily occur when the gear is clamped by two arc-shaped plates driven by two hydraulic telescopic rods, resulting in the inability to position and clamp the gear, thus affecting the processing accuracy.
