Technical Field

[0001] This utility model relates to a spring grinding machine, belonging to the technical field of spring production equipment. Background Technology

[0002] A spring is a common mechanical component, usually made of metal, and possesses excellent elasticity. Its main function is to store and release energy, and it is widely used in various mechanical and electronic devices. After production, springs need to have their ends ground smooth using a spring grinding machine to ensure a flat surface, facilitating stable installation.

[0003] In existing technology, during the grinding process of springs in the feed hole of the turntable, the grinding wheel of the spring grinding machine may get stuck in the feed hole due to the rotation of the grinding wheel and the turntable. After grinding, during the unloading process, a worker needs to use a tool to push the spring out of the feed hole and drop it from the discharge port, which greatly affects the grinding efficiency of the spring grinding machine. Therefore, this utility model also proposes a spring grinding machine to solve the above problems. Utility Model Content

The turntable has several circumferentially shaped material feeding holes. A discharge port is located on the worktable, and a baffle is slidably inserted into the discharge port. A fixing plate is located above the discharge port on the worktable, situated on one side of the turntable. An L-shaped mounting bracket is fixedly connected to the fixing plate, and the L-shaped mounting bracket is coaxially arranged with the discharge port. A set of limiting blocks is provided on the left side of the mounting frame, and an auxiliary plate is provided between the set of limiting blocks. The auxiliary plate is located directly above the feed port. The bottom of the auxiliary plate is provided with an arc-shaped plate that curves to the right. The auxiliary plate is provided with a through groove. A star-shaped set screw is threaded on the left side of the L-shaped mounting frame.
