Fixing clamp for part machining based on intermittent rotary feeding

The invention discloses a part machining fixing clamp based on intermittent rotary feeding, belongs to the technical field of clamps, and aims to solve the problem that when a to-be-machined part is not thoroughly clamped by an existing two-piece type clamp, the part is prone to falling to the ground from the clamp and is damaged. A first hydraulic rod is matched with a driving guide block to drive and control a feeding clamp to be closed to clamp and fix a to-be-machined part, and when the first hydraulic rod pushes the driving guide block to move to the feeding clamp, a U-shaped plate at the bottom of the feeding clamp is synchronously driven to deflect upwards through cooperation of a connecting plate and a moving rod; the elastic net bag on the U-shaped plate wraps, lifts and clamps the bottom of a workpiece, the situation that the workpiece falls off and is damaged when the feeding clamp does not clamp the workpiece thoroughly is avoided, the rotating table intermittently starts and stops rotating, the m
