The final purpose of the utility model is to tighten the bolt on the workpiece to a specific torque.
The work piece is before getting into electric oil pump bolt fastening device, and the bolt on the work piece is screwed up in advance earlier, and the moment of torsion of screwing up the bolt in advance is less than specific moment of torsion, the utility model discloses use first cylinder as the power supply, carry out the standard to the bolt on the work piece that gets into in the electric oil pump bolt fastening device and screw up, the standard is screwed up and is reached specific moment of torsion for the tightening between bolt and work piece. The chain is matched with the fluted disc, and the fluted disc is driven through the chain to first cylinder, and the fluted disc drives box spanner and carries out standard tightening to the bolt. The torque control of the bolt is realized through the pressure sensor, along with the tightening of the bolt, the larger the required torque is, the larger the pressure provided by the first air cylinder is, the pressure in the first air cylinder is identified through the pressure sensor, when the pressure in the first air cylinder reaches a specific value, namely the bolt reaches the specific torque, the controller controls the first air cylinder to stop working, and the standard tightening is completed.
The gear disc type socket wrench is characterized in that a motor is arranged between the support and the socket wrench, a shell of the motor is fixedly connected with the support, a power output end of the motor is connected with the socket wrench, and an overrunning clutch is arranged between the gear disc and the socket wrench.
Through setting up the motor, the link of screwing up in advance between bolt and the work piece also can be accomplished in electronic oil pump bolt fastener. An overrunning clutch is arranged between the fluted disc and the socket wrench, and the fluted disc does not rotate when the motor drives the socket wrench to be screwed down in advance. When the motor reaches a locked-rotor state, the torque provided by the socket wrench is smaller than a specific torque.
The stand is the second cylinder, and the piston and the base plate of second cylinder are fixed and are connected, and the cylinder body of second cylinder links to each other with the support.
The upright column is arranged to be the cylinder, so that the support can move in the vertical direction, the distance between the socket wrench and the base plate is adjusted, and the purpose is to facilitate the workpiece to pass in and out the electric oil pump bolt fastening device.
A bearing is arranged between the cylinder body of the second cylinder and the bracket;
at least 2 workpiece fixing devices are arranged on the base plate and matched with the socket wrench;
the workpiece fixing devices are distributed in a fan shape by taking the upright columns as circle centers.
The workpiece is fixed on the base plate through the workpiece fixing devices, the plurality of workpiece fixing devices allow the socket wrench to be operated in line, and when the workpiece in one workpiece fixing device is screwed down, the workpiece can be loaded or unloaded on other workpiece fixing devices, so that the working flow is optimized, and the production efficiency is improved. The socket spanner switches between different work piece fixing device, is realized through the bearing of support and stand spare, only need rotate the support can.
One end of the chain is connected with the piston of the first cylinder, and the other end of the chain is provided with a balance weight. The other end of the chain is connected with the balance weight through a steel wire, and a pulley can be arranged on the support, so that the chain is ensured to be tightened, and the plane where the chain is located is the same as the plane where the fluted disc is located.
The utility model has the advantages and positive effects that: due to the adoption of the technical scheme, the bolt can be accurately screwed to a specific torque, and the automation degree is high.
