Embodiment Construction

[0026] The present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0027] Non-limiting and non-exclusive embodiments will be described with reference to the following drawings, wherein like reference numerals refer to like parts unless specifically stated otherwise.

[0028] Such as Figure 1-9 The shown tightening shaft suspension device includes a tightening shaft connecting plate 1, a telescopic device, a top plate 6, and a balancer 7. The telescopic device includes a telescopic rod 2 and a guide column 4. The telescopic rod 2 can be displaced along the guiding stroke of the guide post 4. The upper end of the guide column 4 is connected to the top plate 6; the lower end of the telescopic rod 2 is connected to the connecting plate 1 of...

Abstract

The invention discloses a screwing shaft suspension device which comprises a screwing shaft connecting plate, a telescopic device, a top plate and a balancer, wherein the telescopic device comprises atelescopic rod and a guide column; the telescopic rod can move along the guiding stroke of the guide column; the upper end of the guide column is connected with the top plate; the lower end of the telescopic rod is connected with the screwing shaft connecting plate; the balancer is arranged on the top plate; the lifting hook of the balancer hooks the screwing shaft connecting plate; the screwingshaft suspension device further comprises a connecting block; the connecting block is fixed on the upper end face of the guide column and is hinged to the top plate; an interval is reserved between the top surface of the connecting block and the lower surface of the top plate; and the screwing shaft connecting plate is hinged to the lower end of the telescopic rod. The screwing shaft suspension device can reduce the stress for the starting moment when the screwing shaft is moved horizontally and vertically, so that an assembling worker can easily and precisely master the moving force moment and moving speed of the screwing shaft during operation to lower the labor intensity of the assembling worker.

Description

technical field [0001] The invention relates to the field of tool supports, in particular to a tightening shaft suspension device. Background technique [0002] In the assembly process of diesel engines, the assembly of parts needs to be firmly connected by bolts. In order to improve the consistency of the torque quality of parts assembly, electric wrenches or tightening shafts with accurate torque control are generally used to tighten the bolts. The operation increases the labor intensity of the assembly workers. [0003] In the prior art, the fixed connecting rod of the suspension mechanism is fixedly connected to the KPK connecting plate. When the bolt moves horizontally in the axial direction, the telescopic rod, the fixed connecting rod and the KPK connecting plate are driven to move by operating the tightening shaft. The force is very large, especially when the sleeve at the end of the tightening shaft moves close to the bolt head. Often due to excessive force, when t...
