Technical Field
The utility model belongs to nut screw assembly and disassembly tools especially relates to a special electric tool of two nut screw rod dismouting.
Background
Double-ended screws (i.e., double-nut screws) are important connecting elements and are widely used in various connections. When traditional double-end screw connects the object, need adopt two spanners just can screw up, the dismouting process takes time, and intensity of labour is big, and installation quality is not high, and the reliability is poor. Particularly, when the power equipment works, the operation space is limited, the number of operation tools is large, and the operation steps frequently increase the intensity and risk of the work. Although there is also the specialized tool to two nut screw dismouting, it has the clamping structure complicacy, and the connection angle is single, nut socket fixed scheduling problem. Therefore, a novel tool special for disassembling and assembling double-nut screw rods is needed.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a special electric tool of two nut screw rod dismouting of simple structure, nimble efficient.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the special electric tool for disassembling and assembling the double-nut screw mainly comprises a large-torque electric impact wrench, a guide pillar and a screw clamping assembly; the output end of the large-torque electric impact wrench is connected with one end of the replaceable nut sleeve, and the other end of the replaceable nut sleeve is matched with the nut; one end of the rotatable connecting plate is fixed at the motor head of the large-torque electric impact wrench through double offset ring locking screws on two sides, and the other end of the rotatable connecting plate is provided with a linear bearing; the guide post is connected with the rotatable connecting plate through a linear bearing; one end of the guide post, which is far away from the linear bearing, is connected with the screw clamping assembly through a center distance adjusting dovetail groove; the screw clamping assembly mainly comprises C-shaped pressure pliers, the C-shaped pressure pliers are connected with the guide pillar through a center distance adjusting dovetail groove, the C-shaped pressure pliers comprise two C-shaped hooks, the proximal ends of the two C-shaped hooks are hinged, and the distal ends of the two C-shaped hooks are respectively provided with a clamping head.
The chuck is V-shaped.
The hinge of the C-shaped hook is connected and adjusted by an open adjusting screw.
The guide post is a hollow post.
The large-torque electric impact wrench is externally connected with a 24v power supply.
Aiming at the problems of complex operation, high labor intensity, inconvenient operation and the like existing in the existing double-nut screw disassembling and assembling, the inventor designs and manufactures a special electric tool for disassembling and assembling the double-nut screw, which mainly comprises a large-torque electric impact wrench, a guide pillar and a screw clamping component; the output end of the large-torque electric impact wrench is connected with one end of the replaceable nut sleeve, and the other end of the replaceable nut sleeve is matched with the nut; one end of the rotatable connecting plate is fixed at the motor head of the large-torque electric impact wrench through double offset ring locking screws on two sides, and the other end of the rotatable connecting plate is provided with a linear bearing; the screw clamping assembly mainly comprises a C-shaped pressure clamp. The double-nut screw rod of the utility model can be disassembled and assembled only by operating at the movable nut end; the electric driving mode is adopted, and the electric bicycle can be easily used in a space inconvenient to operate. The C-shaped pressure clamping structure can realize rapid clamping and loosening, the diameter of the holding screw rod can be adjusted in a wider range through the opening adjusting screw, and the working efficiency is improved; the rotatable connecting plate structure can realize clamping at any angle, is convenient for working posture and is beneficial to flexible operation; the nut sleeve can be replaced, so that the application range is expanded, and the maintenance and the replacement are more convenient. In a word, the utility model has the characteristics of simple structure, nimble efficient, the operating procedure of reducible two nut screw rod dismouting reduces intensity of labour, improves installation quality, overcomes the potential safety hazard.
