The invention discloses precision part and component spot welding equipment. The precision part and component spot welding equipment comprises a bottom table; a side door is installed on the front surface of the bottom table in an embedded mode; a fixing base is installed on the upper surface of the bottom table; a first vertical board is fixedly installed at the position, close to one side of thefixing base, of the upper surface of the bottom table; a second vertical board is fixedly installed at the position, close to the other side of the fixing base, of the upper surface of the bottom table; and a lifting device is arranged above the second vertical board. The precision part and component spot welding equipment is simple in structure and convenient to operate; a rotary control box cancontain and protect the precision part and component spot welding equipment and prevent the equipment from being damaged; a workbench ascends and descends by a lifting device, the height of the workbench is more suitable for staff accordingly, practicability is increased, the staff are facilitated, and the working efficiency is improved; through arrangement of an air blowing bin, the cooling speed of workpieces is increased, and the cooling time is shortened; and through arrangement of a sleeve and a buffering device, a welding head can be protected, users are prevented from being scaled, andgood protectiveness is achieved.
