Mechanical chip resistor trimming machine

The utility model belongs to the technical field of resistance trimming equipment, and discloses a chip resistor mechanical resistance trimming machine which comprises a base, side plates, a first screw rod, a bottom plate, a second screw rod and a moving device, the two side plates are located on the two sides of the top of the base respectively, the first screw rod is located on the inner wall of the base, the bottom plate is located on the surface of the first screw rod, and the second screw rod is located on the bottom plate. The second lead screw is located between the two side plates, the moving device is located on the outer surface of the second lead screw, a machining table is installed on the top of the bottom plate, and a resistor fixing plate is arranged above the machining table. Due to the fact that the surface of the resistor fixing plate is round, the multiple machining grooves are formed in the resistor fixing plate, and the multiple chip resistors can be placed in the machining grooves at th
