Embodiment approach

[0018] The fastener assembly machine that automatically controls various torque values ​​adopts a mobile structure. The fastener assembly machine can be divided into three parts: mechanical part, hydraulic part and control part. The hydraulic part and the control part are fixed on the mechanical part through a certain shock absorption method, and are pushed to various working positions with the mechanical part. Considering the size of the bolts used by most equipment, and considering the utilization rate and economy of the equipment, it is determined that the bolts with torque requirements less than 600Nm shall be fastened by hydraulic drive, and the bolts with torque requirements above 600Nm shall be fastened by electric drive. . For some occasions that need to be used for specific equipment, the tightening range of hydraulic and electric drives can be adjusted according to the size of the equipment bolts. The tightening torque values ​​of all bolts can be preset before the ...

Abstract

The invention discloses a fastening member assembling machine capable of automatically controlling various torque values. The fastening member assembling machine is characterized in that the fastening member assembling machine is movable and can be pushed to move on the ground, a power portion and a torque sleeve for receiving torque are flexibly connected, a torque transmission joint is replaceable, a flexible shaft for torque transmission and a replaceable fastening bolt head can change into different operation positions at any time, and torque received by each bolt can be automatically stored in a computer after reaching a fixed value and can automatically correspond to management project requirements along with a computer program; the fastening member assembling machine comprises a mechanical portion, a hydraulic portion and a control portion, and the mechanical portion comprises a torque wrench actuating device, a moving trolley, a rack, a speed reducing device, a hydraulic power damping device and a control portion damping device. The fastening member assembling machine is wide in application range, can perform precise-torque-value fastening on various bolts and can record and trace data in real time.

Description

technical field [0001] The invention relates to a fastener assembly device controlled by a microcomputer with various torque values. [0002] Background technique [0003] Bolt connection is a widely used detachable fixed connection, which has the advantages of simple structure, reliable connection, convenient assembly and disassembly, etc. However, under the effects of variable load, vibration and impact, the threaded connection will reduce or even lose the pre-tightening force of the connection, causing serious accidents to machines or equipment. Therefore, some important equipment needs to carry out fastening operation to some important bolts after using for a period of time. There are some problems in domestic bolt fastening operation. The number of bolts is large, the structure of the installation part is complex, the fastening operation is difficult, and the workload is large. For example, there are more than 16,000 bolts in the CRH5 type of motor vehicle, more tha...
