The engine mount bracket needs to play functions such as improving the safety of the engine, reducing noise, and saving costs. At the same time, it also needs to take into account the requirements of improving safety, light weight, and aesthetics. Before the engine mount bracket is put into use, it needs to be finely processed. Before the fine processing, the engine mount bracket needs to be clamped for easy processing.

[0003] Chinese Patent Application No. CN202222136891.6 discloses a fixture for machining an engine mount bracket, including a base. Two sliding seats are arranged on the base to move towards each other. A vertical plate is fixed on the sliding seat. Multiple sliding rods are slidably arranged in the vertical plate. A positioning block for fixing the engine mount bracket is movably arranged at the end of the sliding rod. A spring is sleeved on the sliding rod. One end of the spring abuts against the end face of the vertical plate, and the other end of the spring abuts against the end of the sliding rod close to the positioning block. The utility model can clamp and fix engine mount brackets with different shapes.

[0004] Regarding the technical solution disclosed in the above patent document, through practice, it is considered that there are still the following technical problems:
