Description

A bolt installation tool on a flange surface

technical field

The utility model relates to an installation tool, in particular to a bolt installation tool on a flange surface.

Background technique

Bolts on the flange surface are very common in products. The traditional bolt installation method is to fix one end of the bolt and tighten the nut with a wrench. There are many standard installation tools on the market that can be installed, but the bolts on the flange surface bear the index circle Distribution, there are many bolts, need to be fixed multiple times, the steps are cumbersome, and on the flange surface of some products, the installation space of the bolts is relatively small, and the fixing is very difficult. The installation efficiency of standard installation tools is not high, and the fixing effect is not good. It cannot adapt to the narrow fixing space, resulting in that the bolts on the flange surface cannot be installed in time and effectively.

Utility model content

The technical problem to be solved by the utility model is to provide a bolt installation tool on the flange surface. The counter tool only needs to be installed and fixed once, which solves the problem of multiple times of tedious fixing, and the fixing effect is good, and no additional fixing space is needed. During the tightening process, other bolts will provide the reverse torque required for tightening, which solves the problem of insufficient space for installing bolts on the flange surface.

The technical problems to be solved by the utility model are realized by the following technical solutions.

The utility model relates to a bolt installation tool on a flange surface, which includes an installation tool body, on which several card slots are equally divided, and the installation tool body is a hollow semicircular disc.

Further, the inner diameter of the hollow semicircular disk is larger than the inner diameter of the flange surface.

Further, the distance between the locking grooves on the hollow semicircular disc is the same as the distance between the screw holes on the flange surface.

When using the above-mentioned bolt installation tool, first insert the bolts into the screw holes on the flange surface in sequence, and then embed the installation tool on the flange surface, so that the clamping groove and each bolt head are clamped and fixed, and then the bottom The nut is tightened, and finally the installation tool is taken out to complete the installation work.

Compared with the prior art, the beneficial effects of the utility model are reflected in:

The utility model adopts a disc structure. During the tightening process of one bolt, other bolts will provide the reverse torque required for tightening. There is no need to add other fixing tools. It can also be used in narrow spaces. The installation tool has no strict requirements on processing materials and precision, and the card slot only needs to be processed according to the standard flange surface, which is convenient to produce, can be used many times, has a long service life, and saves economic costs.

detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in Figure 1 and Figure 2, a bolt installation tool on the flange surface, it includes a installation tool body, the installation tool body is provided with a number of card slots 2, the installation tool body is a hollow semicircular disc 1 , the inner diameter of the hollow semicircular disk 1 is greater than the inner diameter of the flange surface 4, and the distance between the slot 2 on the hollow semicircular disk 1 and the slot 2 is the same as the screw hole 3 on the flange surface 4 and The distance between the screw holes 3 is the same.

When working, first insert each bolt into the corresponding screw hole 3 on the flange surface 4 in sequence, and then fit the hollow semicircular disc 1 into the flange surface 4, so that the clamping groove 2 clamps the fixed bolt head to prevent relative movement , then tighten the nut below, and finally take out the hollow semicircular disc 1 to complete the installation work.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
