detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

An embodiment of the bolt installation tool of the present invention is shown in Figures 1 to 4, which is used to insert a bolt 11 into a bolt installation hole in a narrow space, and includes a cylindrical operating rod 1 and two bolt clamping plates 4.

Two mounting planes 2 parallel to each other are provided on the outer peripheral surface of one end of the operating rod 1 , and the mounting planes 2 are provided with through bolt holes 3 . The bolt clamping plate 4 is a rectangular plate with rounded corners at the four corners to avoid scratching the workpiece or the operator. One end of the two rectangular plates in the length direction has a step structure 5 to form a thinner operating rod matching part. The two bolt clamping plates The plate 4 is pressed and fixed on the two installation planes 2 by two compression bolts 6 passing through the two and the nuts that cooperate with the compression bolts 6, forming a clamping interval 7 for clamping the rod of the bolt, and the operating rod 1 becomes an L-shaped structure with the bolt clamping plate 4. In order to adjust the size of the clamping interval 7 and adapt to bolts of different diameters, two adjusting bolts 8 run through the middle of the bolt clamping plate 4 in the length direction. When the adjusting bolts 8 are tightened, the clamping interval 7 becomes smaller, otherwise the clamping interval 7 becomes smaller. big. The thickness of the matching part of the operating rod 1 is smaller than that of the remaining parts, which can make the bolt clamping plate 4 have better elastic deformation ability and make the adjustment of the clamping interval 7 more convenient.

The plate surface of the two bolt clamps 4 is provided with a bolt head clamping groove 9 for accommodating the head of the bolt on the end facing away from the operating rod 1, and the bolt head clamping groove 9 runs through the bolt clamping plate along the thickness direction of the bolt clamping plate 4 4, and has a bolt introduction port 10 arranged on the edge of the bolt clamping plate 4, the width of the bolt head groove 9 is equal to the axial dimension of the head of the corresponding bolt, which can form a more stable positioning for the bolt. In other embodiments, the width of the bolt head slot 9 may also be appropriately increased to accommodate a series of bolts 10 with different head axial dimensions.

When in use, make the axial direction of the bolt 11 consistent with the axial direction of the operating rod 1, and then translate the bolt 11 to the operating rod 1, so that the head of the bolt enters the bolt head slot 9 through the bolt introduction port, and the installation of the bolt is completed. folder. Due to the clamping effect of the two bolt clamps 4, it is necessary to increase the force slightly when installing the bolts, so that the rods of the bolts spread the bolt clamps 4 and are clamped into the clamping interval 7. After the clamping is completed, extend the bolt to the position to be installed through the operating lever 1, adjust the operating lever 1 to drive the bolt to move, so that the bolt enters the bolt installation hole, install the nut, and finally move the tooling along the radial direction of the bolt. The bolts are separated, and the tooling can be taken out.

In the above embodiment, the operating rod 1 and the bolt clips 4 form an L-shaped structure, and the two bolt clips 4 are pierced with adjusting bolts 8 to realize the adjustment of the clamping interval 7 . In other embodiments of the present utility model, the operating rod 1 and the bolt clamping plate 4 can also be in an inclined state, and the opening orientation of the bolt head locking groove 9 can also be consistent with the axial direction of the operating rod 1 or at a certain angle. In addition, in other embodiments, the bolt clamping plate 4 can also use an elastic plate to clamp the stem of the bolt by its own elasticity; in addition, in other embodiments, the bolt clamping plate 4 and the operating rod 1 can also be One-piece structure, for example, a cross-shaped groove is provided at the end of the corresponding rod, one of which forms the clamping interval 7 , and the other forms the bolt head clamping groove 9 . Moreover, in other embodiments, if the bolt clamping plate 4 is thicker, the bolt head clamping groove 9 may also be a clamping groove that does not penetrate through the bolt clamping plate 4 along the thickness direction of the bolt clamping plate 4 .
