Background

The bolt is directly twisted into the threaded hole of the connected piece, a nut is not used, the structure is simpler and more compact than a double-end stud, and the connecting form is used for the condition that one of the two connecting pieces is thicker and does not need to be frequently disassembled (so as not to be damaged by the threaded hole), such as the connecting form adopted by the connection of a valve seat and a cooler in an EGR cooling system.

The bolts are sequentially screwed with the threads of the cooler flange hole and the valve seat flange hole, and the valve seat and the cooler are connected together through the bolts (without nuts) so as to realize the installation and fixation of two products. But the bottom surface of the flange of the product is of an arc structure or has an arc, and can not be independently placed on a workbench. When the two products are assembled, one person is required to hold the valve seat, and one person is required to screw the bolt by using the torque wrench for assembly. According to the drawing and the technological requirements, the assembly moment of the bolt is 25 N.m, when the bolt is screwed by using a torque wrench in a manual assisting state, the product is easy to rotate (mainly assisting people cannot support and steady corresponding products), the torque of 25 N.m is difficult to achieve, and the assembly is inconvenient, difficult and low in efficiency.
