Abstract
The invention provides a fastening method for fixing a bolt of a gyration motor of an excavator, which is characterized by comprising the following steps of building an equipment platform; in the process of screwing the bolt, pushing a torque multiplier to rotate by a pneumatic torque wrench, driving an extending drill by the torque multiplier, and driving a large-scale three-position sleeve selector by the extending drill, thereby transferring a torque to screw the bolt. After the bolt is screwed each time, if an assembly torque satisfies the assembly requirements, a control box sends qualification signals; if the assembly torque is too low or too high, the control box sends alarm signals; meanwhile, a tool is dead locked without rotating to ensure qualified assembly of a single bolt. The invention can solve the problems of time and labor consuming and the like when the gyration motor of the excavator is assembled, thereby lowering the work intensity of a worker and enhancing the assembly efficiency of a link and the work efficiency of a whole excavator.
Description
Technical field
The present invention relates to a kind of fastening method of digger revolving motor set bolt.
Background technology
Rotary motor is the key element in the excavator system, in assembling matching requirements very high, the fastening torque value of fastening bolt is bigger, present stage can only be with wind big gun pretension, operated together by two workmans with torque spanner then and tighten, operating process is wasted time and energy, and has reduced production efficiency.Along with the increasing of excavator output, must improve the production efficiency of each link, have only and improve the efficient that each is produced, assembles link, could improve the output of whole excavator.
Summary of the invention
The fastening method that the purpose of this invention is to provide a kind of rotary motor set bolt is to improve efficiency of assembling.
In order to achieve the above object, technical scheme of the present invention has provided a kind of fastening method of digger revolving motor set bolt, it is characterized in that: step is:
Step 1, the aerodynamic moment spanner is sling with rotatable, on the aerodynamic moment spanner, be connected to the pulley-type balancer, but make aerodynamic moment spanner hand upper and lower, left and right move flexibly, the aerodynamic moment spanner links to each other with control cabinet by power line and source of the gas line, provide required air pressure by control cabinet to the aerodynamic moment spanner, on control cabinet, set simultaneously the torque value of what a correspondence, set up air pressure according to the required torque value of different type of machines for each air pressure;
Step 3, before beginning to twist, set the required total number that tights a bolt of separate unit digger revolving motor by control cabinet, the different type of root is selected different sleeve in large-scale three selector sleeves, program chooser is passed to control cabinet with the information of used sleeve, accesses corresponding program automatically by control cabinet and assembles;
In the process that tights a bolt, promoting torque multiplier by the aerodynamic moment spanner rotates, torque multiplier drives to prolong and bores, prolong moving large-scale three selector sleeves of drilling, thereby moment of torsion transmitted tights a bolt, if bolt hole has foreign matter, can occur when bolt thread portion is destroyed grinding one's teeth, slide dental phenomenon, then send alarm signal by control cabinet;
After tightening a bolt at every turn, the aerodynamic moment spanner will assemble moment of torsion and be sent to control cabinet and implement demonstration by control cabinet, if the assembling moment of torsion satisfy matching requirements then control cabinet send qualified signal, if the assembling moment of torsion is crossed low or too high, then send alarm signal, tool lock stubbornly refuses to change simultaneously, qualified with the assembling of guaranteeing single bolt, simultaneously, show every digger revolving motor residue assembling bolt number with the form that counts down, finish predetermined bolt quantity after, send the qualified green light signals of counting, if when one has been assembled qualified bolt and tightens once more, then can not count to this time assembling.
The present invention can solve phenomenons such as wasting time and energy of digging machine rotary motor when assembling, thereby has reduced workman's working strength, has improved the efficiency of assembling of this link, and then has improved the production efficiency of whole excavator.

The specific embodiment
Specify the present invention below in conjunction with embodiment.
Embodiment
The invention provides a kind of fastening method of digger revolving motor set bolt, step is:
Step 1, as shown in Figure 1, with rotatable 1 aerodynamic moment spanner 2 is sling, on aerodynamic moment spanner 2, be connected to pulley-type balancer 3, but make aerodynamic moment spanner 2 hand upper and lower, left and right move flexibly, aerodynamic moment spanner 2 links to each other with control cabinet 3 by power line and source of the gas line, provide required air pressure by control cabinet 3 to aerodynamic moment spanner 2, on control cabinet 3, set the torque value of what a correspondence simultaneously, set up air pressure according to the required torque value of different type of machines for each air pressure;
Step 3, before beginning to twist, set separate unit digger revolving motor 6 required total numbers that tight a bolt by control cabinet 3, select different sleeve in large-scale three selector sleeves 5 according to different types, program chooser is passed to control cabinet 3 with the information of used sleeve, accesses corresponding program automatically by control cabinet 3 and assembles;
In the process that tights a bolt, promoting torque multiplier by aerodynamic moment spanner 2 rotates, torque multiplier drives to prolong and bores, prolong moving large-scale three selector sleeves 5 of drilling, thereby moment of torsion transmitted tights a bolt, if bolt hole has foreign matter, can occur when bolt thread portion is destroyed grinding one's teeth, slide dental phenomenon, then send alarm signal by control cabinet 3;
After tightening a bolt at every turn, aerodynamic moment spanner 2 will assemble moment of torsion and be sent to control cabinet 3 and implement demonstration by control cabinet 3, if the assembling moment of torsion satisfy matching requirements then control cabinet 3 send qualified signal, if the assembling moment of torsion is crossed low or too high, then send alarm signal, tool lock stubbornly refuses to change simultaneously, qualified with the assembling of guaranteeing single bolt, simultaneously, show every digger revolving motor 6 residue assembling bolt numbers with the form that counts down, finish predetermined bolt quantity after, send the qualified green light signals of counting, if when one has been assembled qualified bolt and tightens once more, then can not count to this time assembling.
Employed equipment is existing device in the said method.
