Description

Nut closing-in multifunctional grabbing claw

Technical Field

The utility model belongs to the technical field of nut closing devices, and particularly relates to a multifunctional grabbing claw for nut closing.

Background

In the production of aviation fasteners, the closing of high-locking and self-locking nuts is a key process; when closing up, the closing up grabbing claw grabs the part and gets and put at specific position, carries out the closing up process. When grabbing, a special closing-in grabbing claw needs to be manufactured according to the size requirement of a nut, the tool is long in production preparation time, the existing closing-in grabbing claw is poor in universality, and only parts with single specifications can be machined; replacement is inconvenient, and frequent replacement can cause the robot to damage and the binding off snatchs the claw and need readjust the original point, and this has seriously influenced product machining efficiency, has prolonged the processing cycle of product.

Disclosure of Invention

The utility model aims to overcome the defects and provide the nut-necking multifunctional grabbing claw which does not need to readjust the original point during replacement, has high processing efficiency and short processing period.

The purpose of the utility model and the main technical problem of solving the utility model are realized by adopting the following technical scheme:

the utility model discloses a nut-closing multifunctional grabbing claw which is characterized in that a claw body is arranged on a base; the side surface of the closing-up claw A is clamped into a closing-up claw seat, the side surface of the closing-up claw seat is clamped into a closing-up claw B, and a bolt respectively penetrates through the closing-up claw A, the closing-up claw seat and the closing-up claw B and is screwed into a nut for connection.

The side surface of the closing claw A is provided with a groove.

The closing-in claw seat is right-angled, and the two side surfaces are respectively provided with a raised head and a groove.

And raised heads and grooves are respectively arranged on two side surfaces of the closing-in claw B.

Compared with the prior art, the utility model has obvious beneficial effects; the technical scheme shows that: the side surface of the closing-up claw A is clamped into the closing-up claw seat, the side surface of the closing-up claw seat is clamped into the closing-up claw B, and the bolt respectively penetrates through the closing-up claw A, the closing-up claw seat and the closing-up claw B to be screwed into the nut for connection. Install binding off claw seat mirror image on the robot, two binding off claws A or two binding off claws B draw in and snatch the nut, when needs replacement, only need unscrew the bolt, replacement binding off claw 1 or binding off claw B, need not readjust the original point when having realized the replacement, machining efficiency is high, and processing cycle is short.

Detailed Description

The details of the embodiments, structures, features and functions according to the present invention are described in the following detailed description and the preferred embodiments.

The utility model discloses a nut-closing multifunctional grabbing claw which is characterized in that a claw body is arranged on a base; the side surface of the closing-in claw A1 is clamped into the closing-in claw seat 2, the side surface of the closing-in claw seat 2 is clamped into the closing-in claw B3, and the bolt 4 respectively penetrates through the closing-in claw A1, the closing-in claw seat 2 and the closing-in claw B3 to be screwed into the nut for connection.

The side of the closing-in claw A1 is provided with a groove.

The closing-in claw seat 2 is right-angled, and raised heads and grooves are respectively arranged on two side faces.

And convex heads and grooves are respectively arranged on two side surfaces of the closing-in claw B3.

During the use, will close up 2 mirror images of claw seat and install on the robot, two close up claws A1 draw in and snatch little nut 5, when needing to snatch big nut 5, dismantle two close up claws A1 respectively, leave two close up claws B3, close up claw B3 draws in and snatchs big nut 5, when needs replace, only need unscrew bolt 4, replacement close up claw 1 or close up claw B3 can.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiment according to the technical spirit of the present invention are within the scope of the present invention without departing from the technical spirit of the present invention.
