The stud bolts to be installed are screwed in, and the stud bolts screwed into the nuts can rotate together with the wrench head, and then screwed into the fan parts to be installed. One end of the limit screw is detachably installed on the pneumatic / The front end of the electric handle, the other end of which is a free end, extends forward and is parallel to the stud bolt screwed into the nut, and the length of the part of the limit screw beyond the chuck is shorter than the stud bolt screwed into the nut length, when the stud bolts are screwed into the fan parts to be installed, the rotation of the stud bolts can be stopped when the free end of the limit screw is in contact with the fan parts to be installed with the stud bolts, thus Effective control of the screwing depth of the stud bolts is realized.

The front end of the pneumatic/electric handle is detachably installed with a clasp, the clasp is located behind the chuck, the limit screw is installed on the clasp, and the periphery of the clasp is inserted with a plurality of cylinder head screw, and the axis of the cylinder head screw is in the diameter direction of the clasp, and the clasp ring realizes its position in the pneumatic/electric handle through the resistance of the multiple cylinder head screws to the corresponding part of the front end of the pneumatic/electric handle. Fix the front end, and loosen the resistance of the cylindrical head screw to the corresponding part of the front end of the pneumatic/electric handle, the installation position of the snap ring at the front end of the pneumatic/electric handle can be adjusted, so as to realize the extension of the clamp to the limit screw Partial length adjustment.

The nut is an aluminum hex nut.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1. Improve the installation accuracy of stud bolts.

2. Simple structure, convenient installation and easy operation.

3. It can effectively control the screwing depth of stud bolts and avoid bolt damage.

Detailed ways

Below in conjunction with specific embodiment the utility model is further described.

Referring to Fig. 1 to Fig. 3, the stud bolt screwing depth control device for wind power generator set provided by this embodiment includes a pneumatic/electric handle 1, a limit screw 2, a snap ring 8, and a wrench head 3 And the nut 5 (specifically aluminum hexagonal nut) that is matched with the stud bolt 4, wherein, the front end of the pneumatic/electric handle 1 is equipped with a rotatable collet 6, and the collet 6 is provided by the pneumatic/electric The drive unit (not shown) inside the handle 1 is driven to rotate. The wrench head 3 can be detachably inserted in the chuck 6 and rotates together with the chuck 6. At the same time, the wrench head 3 is formed with shapes and sizes An accommodating cavity matched with the nut 5, the nut 5 can be detachably installed in the accommodating cavity by using a circlip 7 for the hole to be fixed, for the stud bolt 4 to be installed to be screwed in, and the nut to be screwed in The stud bolt 4 in 5 can be rotated together with the wrench head 3, and then screwed into the fan part to be installed; the snap ring 8 can be detachably installed on the front end of the pneumatic/electric handle 1, and is located at the At the rear, one end of the limit screw 2 is threadedly mounted on the snap ring 8, and is clamped by two small nuts 10, and the other end is a free end extending forward and parallel to the double screw screwed into the nut 5. head bolt 4, and the length of the part of the limit screw 2 beyond the chuck 6 is less than the length of the stud bolt 4 screwed into the nut 5, during the process of screwing the stud bolt 4 into the fan component to be installed, by The free end of the limit screw 2 is in contact with the fan part that needs to be installed with the stud bolt 4, so that the rotation and screwing of the stud bolt 4 can be stopped, thereby realizing effective control of the screw-in depth of the stud bolt 4; in addition, the The periphery of the snap ring 8 is evenly inserted with three cylindrical head screws 9, and the axis of the cylindrical head screws 9 is in the diameter direction of the snap ring 8, and the snap ring 8 is used for the air movement through the three cylindrical head screws 9.
