This bolt tightening device reduces the manufacturing cost and processing difficulty. Greatly reduced, simple structure, convenient operation, unlimited use, suitable for bolts of different sizes, especially when the wrench is not fully equipped.

In order to achieve the above purpose, the utility model provides a bolt tightening device, the bolt tightening device includes a rectangular clamping frame, a tightening rod arranged on the clamping frame, the lower frame of the clamping frame is provided with There is a threaded hole, and the tightening rod includes a screw that passes through the threaded hole, a clamping block that is arranged at the end of the screw, a locknut that is arranged on the screw, and a screw that is arranged at the other end of the screw. Tighten the handle, the clamping block is arranged on the end of the screw rod in the clamping frame, and the clamping block and the locknut are respectively arranged on both sides of the clamping frame.

Preferably, threads are provided on the screw, and the locknut fixes the position of the screw through the threads.

Preferably, the clamping frame is welded by high hardness steel.

Preferably, the bolt tightening device further includes a torque gauge.

Based on the above-mentioned technical scheme, the utility model has the advantages of:

The bolt tightening device of the utility model avoids the problems of many kinds of commonly used wrenches, low work efficiency and high tool cost, greatly reduces the manufacturing cost and processing difficulty, has simple structure, convenient operation, and has higher versatility than special tightening wrenches, etc. It is not only suitable for the tightening of common bolts, but also suitable for the tightening of special screws and bolts.

The bolt tightening device of the utility model greatly reduces manufacturing cost and processing difficulty, has a simple structure, is convenient to operate, is not restricted in use, and is suitable for bolts of different sizes, and is especially suitable when wrenches are not fully equipped, and is convenient and fast.

Detailed ways

The technical solutions of the present utility model will be further described in detail through the drawings and embodiments below.

The utility model provides a bolt tightening device, as shown in Fig. 1 and Fig. 2, which shows a preferred embodiment of the utility model. The bolt tightening device can be made of commonly used steel materials. Specifically, the bolt tightening device includes a rectangular clamping frame 1, a tightening rod arranged on the clamping frame 1, and the lower frame of the clamping frame 1 A threaded hole is provided on the top, and the tightening rod includes a screw 4 set through the threaded hole, a clamping block 3 arranged at the end of the screw 4, a locknut 5 arranged on the screw 4, and a screw nut 5 arranged on the screw 4. The tightening handle 6 at the other end of the screw 4, the clamping block 3 is arranged on the end of the screw 4 in the clamping frame 1, and the clamping block 3 and the locknut 5 are respectively arranged on the Clamp frame 1 on both sides.

As shown in Figure 1, the bolt tightening device consists of two parts, a clamping frame 1 and a tightening rod. The clamping frame 1 has a rectangular structure, welded by steel with good hardness, and has no special requirements on shape and position tolerances. The clamping frame 1 is processed with a threaded hole for connecting a tightening rod. Described tightening bar is made up of screw rod 4, anti-loosening nut 5, clamping block 3, tightening handle 6.

As shown in FIG. 2 , the screw rod 4 is provided with threads, and the locknut 5 fixes the position of the screw rod 4 through the threads, so as to prevent the screws from slipping due to loosening when tightening the screws.

Preferably, the bolt tightening device further includes a torque gauge, and by setting the torque gauge, the bolt can be tightened according to the required torque during use.

The using method of the bolt tightening device of the present utility model can refer to the following steps:

Tightening preparation:

Place the bolt tightening device at a suitable position where the bolts are to be tightened; pick up the bolts to be tightened in place.

Tighten implementation:

a. Align the bolt with the screw hole of the workpiece to be tightened, and manually screw in the button;

b. According to the size of the bolt cap to be tightened, adjust the gap between the tightening device and the bolt cap through the screw rod, put it on the bolt cap, turn the tightening handle of the device, clamp the bolt cap and tighten the locknut;

c. Rotate the tightening handle until the bolt is tight.

The bolt tightening device of the utility model avoids the problems of many kinds of commonly used wrenches, low work efficiency and high tool cost, greatly reduces the manufacturing cost and processing difficulty, has simple structure, convenient operation, and has higher versatility than special tightening wrenches, etc. It is not only suitable for the tightening of common bolts, but also suitable for the tightening of special screws and bolts.

The bolt tightening device of the utility model greatly reduces manufacturing cost and processing difficulty, has a simple structure, is convenient to operate, is not restricted in use, and is suitable for bolts of different sizes, and is especially suitable when wrenches are not fully equipped, and is convenient and fast.
