Electric oil pressure pulse type assembling tool

Abstract

The invention discloses an electric oil pressure pulse type assembling tool which comprises a motor and an oil pressure pulse assembly provided with a striking shaft. The motor, the oil pressure pulse assembly and the striking shaft are all arranged on a shell. A detector I used for monitoring the rotating speed of an output shaft, a detector II used for monitoring the striking number of the striking shaft and a controller connected with the detector I, the detector II and the motor are further arranged in the shell. The controller automatically shuts down the motor when the pulse frequency reaches a set value. The pulse frequency is the acceleration fluctuation frequency obtained on the basis of the rotating speed and the striking number. According to the electric oil pressure pulse type assembling tool, the motor is utilized for driving the oil pressure pulse assembly to output torque outwards, the oil pressure pulse assembly has the stable power transmission characteristic, the detector I, the detector II and the controller can accurately monitor the output shaft and the striking shaft and control starting and stopping of the motor in a feedback mode, the constant torque function is achieved on the basis of the oil pressure pulse assembly, the output torque is accurately controlled, and the working performance is improved.

Description

Technical field [0001] The present invention relates to the field of electric tools, and more particularly to an electric oil pressure pulse assembly tool. Background technique [0002] The electric screwdriver is a power energy that can be converted to the threaded coupling of the threaded coupling in the outside of the electric motor, which is used to tighten and disassemble the threaded coupling, which can be widely used in home appliances, automobiles, motorcycles and other industries. [0003] In order to ensure the quality of the product, the operator often needs to make the electric screwdriver to complete the installation of the internal threaded joints in a specific torque, in other words, the electric screwdriver with a gate can protect the installation effect of the internal threaded coupling, which in turn guaranteed the product. Assembly quality. [0004] At present, in the common electric screwdriver, although the electrical screwdriver can achieve a torsion, the to...

AI Technical Summary

Problems solved by technology

[0004] Among the current common electric screwdrivers, although some electric screwdrivers can achieve constant torque, their torque transmission accuracy and detection accuracy are relatively low. There is a large error in the expected torque of the personnel, which not only affects the assembly quality of the product and its threaded joints, but also is not conducive to the life and operation safety of the electric screwdriver itself.
