Description

Technical Field

[0001] The utility model relates to the field of tightening machines, in particular to an angled handheld tightening machine. Background Art

[0002] At present, nuts are tightened mainly by tools such as screwdrivers, and manual tightening is very slow and laborious. It is difficult to tighten when encountering components that are difficult to fix. Therefore, an angled handheld tightening machine is needed. The patent authorization announcement number is CN202212931U. A nut tightening machine is used to tighten the nuts of wheels. It includes a tightening machine body with a tightening shaft, and one end of the tightening shaft is fixedly connected to the tightening machine body. This new type has the problems of deviation caused by operational errors, cable constraints, the need to not move over a large range at the site of use, cable wear and breakage causing failures, poor tightening quality, inability to control torque and angle, errors, easy to damage items, and waste of costs.

[0003] Therefore, it is necessary to design a relatively light and convenient one that can be held by personnel and can avoid the deviation caused by operational errors. Through the precise control of the tightening process, the generation of elastic deformation stress of the connection and the heat generated by the bolt can be controlled, the connection quality can be better controlled, and product quality problems can be discovered in time, such as thread quality, changes in screw quality, misinstallation, missing installation and other human operation problems, to maximize the closed-loop control of the man-machine-material-method loop, and avoid product tightening quality accidents. Torque and angle detection are both direct detections, which minimizes the errors caused by indirect detection. Wireless data transmission avoids the constraints of cables, and is convenient for the use of multiple degrees of freedom and large-scale movement requirements on site, and avoids failures caused by cable wear and breakage. Different workpieces can automatically match different monitoring programs to avoid the influence of human factors, and realize digital traceability of the process of a specific workpiece and a certain screw, which greatly reduces the traceability cost. Angle handheld tightening machines are very necessary. Utility Model Content
