Description
Technical field
The present invention relates to a kind of power transformation device box body bolt batch fastening device.
Background technology
The casing of power transformation device when mounted, in order to ensure to become electrical safety, multiple positions on casing all need fastening anti-theft bolt, staff needs to be tightened every root bolt by electric screw fastening device, but multiple anti-theft bolts at some positions on casing, due to position angle restriction, electric screw fastening device cannot reach this place and tighten bolt, workman can only carry out craft by spanner and tighten, and not only workload is comparatively large, and reduces operating efficiency.
Summary of the invention
the object of this invention is to provide a kind of power transformation device box body bolt batch fastening device.Structure of the present invention is simple, can be tightened by the multiple bolts become on electrical appliance box body rapidly simultaneously, and can carry out electronic tightening to the bolt of some privileged sites, increase work efficiency, reduce labour intensity.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
Power transformation device box body bolt batch fastening device, described device comprises bolt fixing mechanism and nut tightening mechanism, and described bolt fixing mechanism comprises pressing plate and top board, and pressing plate is installed with pin, and pressing plate is connected with roof movement by pin, and top board is provided with groove; Described nut tightening mechanism comprises handle, and handle is connected with motor by pipe, and the dwang of motor is connected with nut clamping device.
During work, by the groove of multiple bolt by top board, threaded rod is through top board, its nut is erected on top board, is then connected with top board by pressing plate, is moved by bolt along groove, adjustment position, its threaded rod is coordinated with the interporal lacuna on transformer-cabinet, then pressing plate is moved down, the nut of pressing plate bottom surface nestled bolt; Now, nut is positioned in nut clamping device, then nut clamping device is contacted with the threaded rod of bolt, nut is contacted with the threaded rod of bolt, then hand-held handle, start motor, motor drives nut clamping device, indirectly drives nut to be connected with bolt thread, as stated above, bolted mechanism can arrange multiple motor, can be tightened by multiple bolt fast simultaneously.
Preferably, described bottom surface, pressing plate two ends is installed with the pin vertical with pressing plate respectively, and top board two ends are respectively equipped with through hole, and pin coordinates with via clearance.
Preferably, the handle of nut tightening mechanism is connected with motor by metal hose.
Staff can pass through metal hose, adjustment motor and nut clamping device are relative to the position of bolt, metal hose easily bends, also there is good kenel retentivity simultaneously, conveniently fastening nuts is carried out to the bolt at some privileged sites places on transformer-cabinet, the technical purpose that the present invention wants to realize can be realized.
Preferably, the quantity of described metal hose is not less than two, every root connection by metal hose one motor.
Preferably, described nut clamping device is six square tubes, and the lower end of six square tubes is connected with the dwang of motor, and six square tube from top to bottom reduce gradually.
Because the bolt many employings hex nut becoming electrical appliance box body use in prior art carries out fastening, so the upper end of nut clamping device is designed to six square tubes in the present invention, hex nut can be put into six square tubes, hex nut falls in six square tubes, because six square tube are up big and down small, and its larger internal diameter tube and hex nut matched in clearance, so hex nut only can drop down onto in six square tubes bottom large diameter place, fix relative to six square tube positions.When motor drives six square tubes to rotate, hex nut is static relative to six square tubes, and is connected with bolt thread, and threaded rod, through hex nut, enters the less inner radius of six square tubes.After hex nut tightens, six square tubes are separated with hex nut and threaded rod.
Compared with prior art, tool has the following advantages in the present invention: structure of the present invention is simple, easy to make, rapidly the multiple bolts become on electrical appliance box body can be tightened simultaneously, and electronic tightening can be carried out to the bolt of some privileged sites, increase work efficiency, reduce labour intensity.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of top board in the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1-2, power transformation device box body bolt batch fastening device, comprise bolt fixing mechanism and nut tightening mechanism, described bolt fixing mechanism comprises pressing plate 2 and top board 1, bottom surface, pressing plate 2 two ends is installed with the pin 3 vertical with pressing plate 2 respectively, top board 1 two ends are respectively equipped with through hole 4, pin 3 and through hole 4 matched in clearance, and top board 1 is provided with groove 5; Described nut tightening mechanism comprises handle 6, and handle 6 is connected with motor 8 by metal hose 7, and the dwang of motor 8 is connected with the lower end of six square tubes, and in six square tubes, the internal diameter at 10 places is greater than the internal diameter at 9 places.The quantity of described metal hose 7 is not less than two, and every root metal hose 7 connects a motor 8.
During work, by the groove 5 of multiple bolt 11 by top board 1, the threaded rod of bolt 11 is through top board 5, its nut is erected on top board 1, then by the through hole 4 of top board 1 and pin 3 recessed bond ing of pressing plate 2, is then moved along groove 5 by bolt 11, adjustment position, its threaded rod is coordinated with the interporal lacuna on transformer-cabinet, then pressing plate 2 is moved down, the nut of pressing plate 2 bottom surface nestled bolt 11; Now, hex nut is positioned in six square tubes, hex nut and six square tube 10 place matched in clearance, so hex nut to drop down onto in six square tubes bottom 10 places, 9 tops, place, fixes relative to six square tube positions.Then hand-held handle 6, by bending metals flexible pipe 7, adjustment motor 8 and six square tubes are relative to the position of bolt 11, after the threaded rod of bolt 11 contacts with six square tube hexagonal socket nuts, start motor 8, motor 8 drives six square tubes, indirectly drives hex nut to be threaded with bolt 11, threaded rod, through hex nut, enters 9 places in six square tubes.After hex nut tightens, six square tubes are separated with hex nut and threaded rod.As stated above, the hex nut in multiple six square tubes that the multiple motor 8 in the present invention connect can carry out fastening to multiple bolt 11 simultaneously.
