Abstract

The invention discloses an electric tightening and loosening device for a tailstock of a digital wiring unit and a method. The device is mainly included and comprises a clamping mechanism and a rotating driving mechanism; the clamping mechanism comprises a chuck; multiple rubber wheel rotating shafts are evenly distributed on and surround the chuck; rubber wheels are mounted in positions, extending out of the chuck, of front ends of the rubber wheel rotating shafts; back ends of the rubber wheel rotating shafts are connected with shaft sleeves rotationally arranged on an end cover; the rotating driving mechanism comprises a motor; an output shaft of the motor is connected with a gear transmission mechanism; and an output shaft of the gear transmission mechanism is connected with the shaft sleeves. With the device, the rotating shafts and the rubber wheels are driven by the motor to rotate, and the tailstock of the digital wiring unit is tightened and dismounted rapidly under the effect of the clamping force of the chuck.

Description

technical field

[0001] The invention relates to an electric tool, especially an electric tool for fast tightening and dismounting of a tailstock of a digital distribution unit of a digital distribution frame (cabinet) in a power communication machine room and an operator's communication machine room. Background technique

[0002] The digital distribution frame (cabinet) is used for signal wiring and conversion between communication equipment, and the main wiring module is a digital wiring unit, such as figure 1 As shown, the digital wiring unit is mainly composed of panels, L9 five-piece set, conductive plate, grounding wire, cable fixing bracket and other components; L9 five-piece set is composed of Y-shaped head, double pass, and tailstock. Since the distance between the digital units of each system is relatively close, it is inconvenient to connect all the coaxial cables. After the coaxial cable and the tail pipe are welded or crimped, when the tailstock is tightened by h...

Embodiment Construction

[0031] Such as Figure 2-6 As shown, an electric tensioning device for a tailstock of a digital distribution unit includes a clamping rotation mechanism and a driving mechanism, the clamping rotation mechanism includes a clamping adjustment mechanism and a rotation mechanism, and the clamping adjustment mechanism includes an outer sleeve 1, The outer sleeve 1 is provided with a collet 2 that can be expanded and tightened. The collet 2 is a hollow structure and has a hole suitable for the rear end of the tailstock. When unscrewing or tightening, the The positioning and initial positioning of the tailstock tail cover ensure that the tail cover and the welded cables at the rear end will not be twisted arbitrarily during installation or disassembly, so as to avoid loosening of the cable and reduce the possibility of scrapping. The front end of the collet 2 is thick and the rear end is thin, and the side wall of the front part of the collet 2 is uniformly surrounded by a plurality ...
