The beneficial effects of the utility model are：Utility model device is by installing horizontal location sensor, perpendicular positioning
Sensor, vertically oriented sensor can obtain the spatial position of spanner, realize for assembling bolt fixation and recognition, can be used for about
The working path of beam spanner, the torque relaxation phenomenon occurred when preventing scene from tightening out of order improve assembling quality；It is logical
The gravity of spanner itself can be balanced, offset spanner generated reaction force, this practicality in rundown process by crossing installation Anti-gravity device
New device structures are simple and convenient to operate, it is no longer necessary to which worker's arm or body bear the gravity or spanner of spanner itself
The generated reaction force in rundown process greatly reduces the labor intensity of worker, reduces the consumption of muscle power, improves efficiency of assembling.

Specific implementation mode
The utility model is done below by Figure of description and is further described in detail.
As shown in attached drawing 1-2, the utility model provides a kind of bolt positioning and recognizing device for assembly, the device packet
Frame 1, horizontal guide rail 2, vertical guide rail 3, mechanical arm 4, telescopic arm 5 are included, horizontal guide rail 2 and vertical guide rail are installed on frame 1
3,2 one end of horizontal guide rail is slidably connected with vertical guide rail 3, and horizontal location sensor 6, vertical guide rail 3 are provided on horizontal guide rail 2
On be provided with perpendicular positioning sensor 7；4 one end of mechanical arm is slidably connected with horizontal guide rail 2, and the other end is socketed with telescopic arm 5, stretches
5 end of contracting arm is equipped with spanner 9, and vertically oriented sensor 8 is provided on mechanical arm 4.
Utility model device is by installing horizontal location sensor 6, perpendicular positioning sensor 7, vertically oriented sensor
8, the coordinate data in tri- directions X, Y, Z of spanner 9 can be obtained, can be used for constraining the operation of spanner 9 in 9 operation of spanner
Path, the torque relaxation phenomenon occurred when preventing scene from tightening out of order improve assembling quality.
In the technical solution of the utility model, 2 one end of horizontal guide rail is connect by sliding bearing with vertical guide rail 3, machinery
Arm 4 is connect by sliding bearing 12 with horizontal guide rail 2, and mechanical arm 4 can be in horizontal, Vertical Square upward sliding, and telescopic arm 5 is nested
In mechanical arm 4, spanner 9 can lower slider in the vertical direction along telescopic arm 5.
Preferably, mechanical arm 4 is built-in with Anti-gravity device 10, and Anti-gravity device 10 can offset spanner 9 right
