The lateral clamping assembly for limiting the lateral space of the automobile engine support workpiece 2 is installed on the base 1 near the middle position. The lateral clamping assembly limits the raised position of the end of the automobile engine support workpiece 2, so that the automobile engine support workpiece 2 can also be supported during multi-faceted processing without shaking or shifting, thereby ensuring processing accuracy and achieving multi-faceted processing with one clamping. The main clamping part for pressing the automobile engine support workpiece 2 is installed on the base 1; the auxiliary support assembly cooperates with the main clamping part to support the automobile engine support workpiece 2, preventing the automobile engine support workpiece 2 from being deformed due to excessive force at a local position.

[0048] Among them, the basic positioning assembly, the angular positioning assembly, the auxiliary support assembly, the lateral clamping assembly and the main clamping member are connected to the channels at corresponding positions.

[0049] The present utility model records a processing fixture for an automobile engine bracket, which adopts a basic positioning component, an angular positioning component, an auxiliary support component, a lateral clamping component and a main clamping member to achieve clamping and fixing of the automobile engine bracket workpiece 2. The area of ​​the automobile engine bracket workpiece 2 blocked by the entire clamping is small, and the various components cooperate to achieve clamping. The clamping force at each position is small, which can effectively avoid deformation of the automobile engine bracket workpiece 2 and can meet the needs of multi-faceted processing. It has good use effect and has a good prospect of use.

[0050] The present invention describes a processing fixture for an automobile engine bracket. The positions of the various components in the fixture are rationally designed, so that the automobile engine bracket workpiece 2 can be clamped in one go. The automobile engine bracket workpiece 2 is easy to assemble and disassemble, and the replacement efficiency is high. The entire fixture has a simple and compact structure, is easy and quick to operate, is safe and reliable to use, has good use effects, and has a good prospect for use.

[0051] When in use, the automobile engine bracket workpiece 2 is placed on the basic positioning assembly. At this time, the angular positioning assembly limits the automobile engine bracket workpiece 2, and then the lateral clamping assembly is started. The lateral clamping assembly clamps the automobile engine bracket workpiece 2, and the auxiliary support assembly and the main clamping component are started and cooperated to fix the position of the automobile engine bracket workpiece 2.
