Description

Technical Field

[0001] The utility model relates to an anti-rotation tool for assembling and tightening beam end brackets, belonging to the technical field of mine car assembly. Background Art

[0002] During the assembly of mine cars, it is necessary to perform torque setting operations on the bolts and nuts of the key component beam end brackets. During the tightening process of the bolts and nuts, it often occurs that when one of them is turned, the other one will rotate accordingly. Especially for larger bolts and nuts, the rotation situation is more serious, resulting in the inability to ensure the effective torque. Conventional operations require two people to jointly tighten the bolts. That is, one person uses an open-ended wrench to hold the bolt in place while the other person performs the tightening operation. This operation is time-consuming and laborious. Especially when using an electric wrench to tighten, due to manual holding, it also increases the risk. Summary of the Invention

[0003] Aiming at the problems existing in the above-mentioned prior art, the utility model provides an anti-rotation tool for assembling and tightening beam end brackets, which can be adapted to an electric tightening gun, improve production efficiency, ensure torque output, reduce noise, and reduce the labor intensity of workers.

[0004] In order to achieve the above object, an anti-rotation tool for assembling and tightening beam end brackets adopted by the utility model includes:

[0005] A limit reaction plate, with a second reaction sleeve installed at one end thereof;

[0006] A movable reaction plate, with a first reaction sleeve installed at one end thereof. The movable reaction plate is movably installed inside the limit reaction plate and slides along the inside of the limit reaction plate to adjust the center distance between the first reaction sleeve and the second reaction sleeve;

[0007] A handle, rotatably installed on the limit reaction plate. Rotating the handle is used to fix the movable reaction plate and the limit reaction plate, so that the first reaction sleeve and the second reaction sleeve are reciprocal reaction arms.

[0008] In some embodiments, the handle is a 7-shaped bolt, and the limit reaction plate is provided with internal threads matching the 7-shaped bolt.

[0009] In some embodiments, the bottoms of the first reaction sleeve and the second reaction sleeve are provided with slot holes, and the shape of the slot holes matches the shape of the bolt head.

[0010] In some embodiments, the limit reaction plate includes a limit plate body and a fixed plate body. The limit plate body is U-shaped, and the fixed plate body is installed at the end of the limit plate body and cooperates with the limit plate body to form a hollow structure. The movable reaction plate is movably installed inside the hollow structure.

[0011] In some embodiments, the bottom of one end of the fixed plate body is connected to the second reaction force sleeve through the second connecting plate body.

[0012] In some embodiments, the movable reaction force plate includes a movable plate body, the movable plate body is U-shaped, and the bottom of one end of the movable plate body is connected to the first reaction force sleeve through the first connecting plate body.

[0013] In some embodiments, both the limit reaction force plate and the movable reaction force plate are of an integral structure.

[0014] In some embodiments, the center distance between the first reaction force sleeve and the second reaction force sleeve is 140 - 215 mm.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] 1. By clamping the heads of two bolts respectively with two reaction force sleeves, and through the movable connection and fastening of the movable reaction force plate and the limit reaction force plate, the two reaction force sleeves act as reaction force arms for each other to achieve anti-rotation during the tightening process.

[0033] As Figures 1-6 shown, a rotation prevention tooling for beam end bracket assembly tightening includes a limit reaction plate 3, a movable reaction plate 2 and a handle 4;

[0034] One end of the limit reaction plate 3 is installed with a second reaction sleeve 5;

[0035] One end of the movable reaction plate 2 is installed with a first reaction sleeve 1. The movable reaction plate 2 is movably installed in the limit reaction plate 3, and the movable reaction plate 2 slides along the inside of the limit reaction plate 3 to adjust the center distance between the first reaction sleeve 1 and the second reaction sleeve 5;

[0036] The handle 4 is rotatably mounted on the limiting reaction plate 3. Rotating the handle 4 is used to fix the movable reaction plate 2 and the limiting reaction plate 3, and make the first reaction sleeve 1 and the second reaction sleeve 5 act as reaction force arms for each other, ensuring that the torques of the two reaction sleeves are balanced with each other during the tightening process, so as to achieve the purpose of preventing rotation during the tightening operation.

[0037] In some embodiments, as Figure 1 , Figure 2 shown, the handle 4 is a 7-shaped bolt, and the limiting reaction plate 3 is provided with internal threads matching the 7-shaped bolt. The 7-shaped bolt can rotate. Rotating clockwise is used to tighten the tooling to ensure that the reaction sleeve clamps the bolt without loosening, and rotating counterclockwise is used to release the force. After the tightening gun 7 tightens the bolt nut, the tooling can be easily disassembled; through the cooperation of the 7-shaped bolt and the thread, the movable reaction plate 2 is extruded for limiting and fixing, and the bolt can be easily clamped before the tightening operation without the aid of other tools, and the tooling can be quickly disassembled after the tightening operation.

[0038] In some embodiments, as Figure 1 shown, the bottoms of the first reaction sleeve 1 and the second reaction sleeve 5 are provided with slot holes, and the shape of the slot holes matches the shape of the bolt head, and the reaction sleeve is relied on to play a role in limiting, anti-torsion and preventing the bolt from following rotation.

[0039] In some embodiments, as Figure 1 , Figure 6 shown, the limiting reaction plate 3 includes a limiting plate body 31 and a fixing plate body 32. The limiting plate body 31 is U-shaped, and the fixing plate body 32 is installed at the end of the limiting plate body 31 and cooperates with the limiting plate body 31 to form a hollow structure. The movable reaction plate 2 is movably installed inside the hollow structure, and the movable reaction plate 2 can slide inside the hollow structure. By adjusting the fixing position of the movable reaction plate 2 on the fixing plate body 32 to adapt to bolts with different spacings, it is possible to ensure easy capping through spacing adjustment. One end bottom of the fixing plate body 32 is connected to the second reaction sleeve 5 through a second connecting plate body 33, and the adjustment range of the center distance between the first reaction sleeve 1 and the second reaction sleeve 5 is 140-215 mm.

[0040] In some embodiments, as Figure 1 , Figure 5 and Figure 6 shown, the movable reaction plate 2 includes a movable plate body 21. The movable plate body 21 is U-shaped, and one end bottom of the movable plate body 21 is connected to the first reaction sleeve 1 through a first connecting plate body 22. The position is adjusted by the cooperation of the U-shaped movable plate body 21 and the U-shaped limiting plate body 31 for sliding, and at the same time, the U-shaped structure can prevent the movable plate body 21 from slipping out of the limiting reaction plate 3.

[0041] In some embodiments, the limit reaction force plate 3 and the movable reaction force plate 2 are both of integral structure, with strong practicability. The reaction sleeves on the limit reaction force plate 3 and the movable reaction force plate 2 can be replaced to adapt to different bolts and nuts, so as to meet the use requirements of product models with double-bolt fastening structures.

[0042] When assembling the beam end support, as Figures 7-9 shown, first adjust the position of the movable reaction force plate 2 on the limit reaction force plate 3, and sleeved the holes and grooves on the first reaction sleeve 1 and the second reaction sleeve 5 onto the heads of the first bolt 6 and the second bolt 9 to be tightened, so that the center distance between the first reaction sleeve 1 and the second reaction sleeve 5 is equal to the center distance between the two bolts;

[0043] Then rotate the handle 4 clockwise, and the movable reaction force plate 2 is pressed and fixed on the limit reaction force plate 3 by the pressing part 41 at the top of the handle 4. At this time, the first reaction sleeve 1 and the second reaction sleeve 5 are mutual reaction force arms, achieving the purpose of preventing the bolts from rotating. After tightening the nuts 8 on the two bolts with a tightening gun 7, the operator rotates the handle 4 counterclockwise to release the force, and the tooling can be easily removed. The whole process is convenient to operate and does not require any tools.

[0044] In addition, those skilled in the art can understand that although some embodiments described herein include certain features contained in other embodiments rather than other features, the combination of the features of different embodiments also means that it is within the protection scope of the present invention and forms different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
