Problems solved by technology

At present, the tightening torque of bolts (or nuts) is controlled by electric or pneumatic tightening tools with a fixed torque. For the manual assembly process of bolts (or nuts) that require a certain assembly tightening sequence, the control of the bolt assembly sequence The method is to strictly stipulate the specific tightening sequence in the assembly process, and the assembler will complete it according to this sequence. Although this method is simple, the tightening sequence is completely controlled by the assembler, and it is inevitable that there will be mistakes and leaks, which cannot be realized. Process quality control does not meet the requirements of modern industrialized mass production

Embodiment Construction

[0013] Such as Figure 1 Shown, the present invention includes: angular displacement sensor 1, angular displacement sensor 2, linear displacement sensor 3, piston cylinder 4, strut 5, bolt tightening tool 6, hinged head 7, rotary arm 9, rotary joint 10, rotary bracket 11. Among them, the rotary mechanism composed of the rotary bracket 11, the rotary joint 10, the rotary arm 9 and the angular displacement sensor 1, the hinged rotary mechanism composed of the hinged joint 7 and the angular displacement sensor 2, the strut 5, the piston cylinder 4, the linear displacement sensor 3, the bolt The vertical up and down movement mechanical mechanism that tightening tool 6 forms.

[0014] In the slewing mechanism, the slewing arm 9 is connected to the slewing joint 10 on the equipment support through a pin shaft 14, and the angular displacement sensor 1 is on the slewing joint 10 to form a first-stage slewing mechanism in the horizontal direction. The pin connected to the slewing arm 9...

Abstract

It is a bolt alignment order control device in the mechanical aligning technique field, which comprises two angle displacement sensors, linear sensor, piston cylinder, raising bar, bolt screwing tool, hinged head, turning arm, turning joint and turning rack. And the turning rack and turning joint and turning arm and the first angle displacement sensor form the turning structure; the second angle displacement sensor, hinged head form hinged turning structure; the raising bar, piston cylinder, linear displacement sensor and bolt screwing tool form vertical moving mechanical structure.

Description

technical field [0001] The invention relates to a quality control device in the technical field of machinery, in particular to a bolt assembly sequence control device in the assembly process of mechanical parts. Background technique [0002] Engines and oil pumps are important components in the automotive industry. In the assembly process of the cylinder head of the engine and the shaft cover (or front housing) of the oil pump, there are clear regulations on the tightening torque of important bolts and nuts, and at the same time, there are strict requirements on the tightening sequence of the tightening process. In the assembly production process, the precise control of the torque and tightening sequence when tightening important bolts and nuts is the key to ensuring product performance and assembly quality. [0003] After searching the prior art literature, no literature reports identical or similar to the subject of the present invention have been found. At present, the ...
