Description

Technical Field

[0001] The utility model belongs to the technical field of assembly tools, and in particular relates to a thin-necked hole-bar rotation auxiliary tool. Background Art

[0002] When assembling and disassembling components with cylindrical slender rods, a clamp is usually used to clamp the slender rod to rotate the slender rod to complete the slender rod assembly and disassembly operations. When a clamp is used to clamp the slender rod, the friction between the clamp and the slender rod is used to drive the slender rod to rotate. However, during operation, the clamp is likely to cause the slender rod to deform or wear and damage. Therefore, a through hole arranged along the radial direction of the slender rod is processed on the slender rod, and a pin is inserted into the through hole to assist the rotation of the slender rod. A tool can be used to apply a rotational force to the pin to drive the slender rod to rotate. However, the pin is prone to breakage or damage to the through hole during use. This makes the slender rod inconvenient to operate during rotation, and is not easy to assemble and disassemble. Utility Model Content

A first arc-shaped hole for accommodating a thin rod 7 is provided on one side of the first clamping block 1; the second clamping block 2 is hingedly arranged relative to the first clamping block 1, and the hinge shaft 6 of the first clamping block 1 and the second clamping block 2 is arranged parallel to the axis of the first arc-shaped hole, and a second arc-shaped hole for accommodating a thin rod 7 is provided on one side of the second clamping block 2, and the first arc-shaped hole and the second arc-shaped hole constitute a mounting hole for mounting the thin rod 7; the latch 3 is slidably matched with the through hole on the thin rod 7, and a guide hole for accommodating the latch 3 is provided on the first clamping block 1 and the second clamping block 2. When the thin rod 7 is clamped between the first clamping block 1 and the second clamping block 2, the two ends of the latch 3 are located inside the guide hole, and the middle part of the latch 3 is located inside the through hole on the thin rod 7.

[0024] Compared with the prior art, the thin-necked rod rotation auxiliary tool provided in this embodiment is provided with a first clamping block 1 and a second clamping block 2 which are hinged to each other, and a first arc hole and a second arc hole are respectively provided on the opposite sides of the first clamping block 1 and the second clamping block 2. When the first clamping block 1 and the second clamping block 2 are closed together, the first arc hole and the second arc hole form a mounting hole for accommodating the thin rod 7, and a guide hole for installing the plug 3 is provided on the inner wall of the first arc hole and the second arc hole. When the thin rod 7 with a through hole is clamped between the first clamping block 1 and the second clamping block 2, the plug 3 can be inserted into the guide hole and the inside of the through hole. By providing the guide hole, the guiding length of the plug 3 can be increased, and when the tool is used to drive the first clamping block 1 and the second clamping block 2 to rotate synchronously, the risk of bending and breaking of the plug 3 can be reduced, so that it is convenient to drive the thin rod 7 to rotate, thereby facilitating the assembly and disassembly of the thin rod 7 by the operator.

[0025] Specifically, in this embodiment, when the first clamping block 1 and the second clamping block 2 are closed together, the axes of the guide hole on the first clamping block 1 and the guide hole on the second clamping block 2 are located on the same axis.

[0026] In some embodiments, the first clamping block 1 and the second clamping block 2 may be used as follows: Figure 1 , Figure 2 See also Figure 1 , Figure 2 A fixing member 4 is also provided between the first clamping block 1 and the second clamping block 2 for fixing the second clamping block 2 to the first clamping block 1 when the thin rod 7 is clamped inside the mounting hole. The fixing member 4 is provided so that when the first clamping block 1 and the second clamping block 2 are closed together, the first clamping block 1 and the second clamping block 2 can be fixed together, so that it is convenient to clamp the first clamping block 1 and the second clamping block 2 with a tool later.

[0027] In some embodiments, the fixing member 4 may be Figure 1 , Figure 2 The structure shown. Figure 1 , Figure 2 , the first clamping block 1 and the second clamping block 2 are provided with positioning holes for installing the fixing member 4, and the axis of the positioning hole is arranged parallel to the axis of the installation hole. The fixing member 4 adopts the form of an axle pin, and positioning holes are arranged on both the first clamping block 1 and the second clamping block 2. When the first clamping block 1 and the second clamping block 2 are closed together, the positioning hole on the first clamping block 1 overlaps with the positioning hole on the second clamping block 2 and is arranged coaxially. The fixing member 4 is a columnar structure, and the fixing member 4 can be inserted into the positioning hole to prevent the first clamping block 1 and the second clamping block 2 from rotating relative to each other. The first clamping block 1 and the second clamping block 2 are relatively fixed, and the structure is simple and the operation is convenient.

[0028] In some embodiments, the second clamping block 2 may be Figure 1 , Figure 2 and Figure 3 See also Figure 1 , Figure 2 and Figure 3 , a guide block 21 is protruding from one side of the second clamping block 2 provided with the second arc-shaped hole, a guide groove 11 for accommodating the guide block 21 is provided on one side of the first clamping block 1 provided with the first arc-shaped hole, and the fixing member 4 is provided through the guide block 21 and the side wall of the guide groove 11.

A guide groove 11 corresponding to the guide block 21 is provided on the first clamping block 1. When the first clamping block 1 and the second clamping block 2 rotate in the closing direction, the guide block 21 can slide into the inside of the guide groove 11, playing a certain guiding role, and preventing the first clamping block 1 and the second clamping block 2 from being misaligned along the axial direction of the hinge shaft 6. It is ensured that when the first clamping block 1 and the second clamping block 2 are in a closed state, the guide hole on the first clamping block 1 and the guide hole on the second clamping block 2 are in a coaxial state, so as to facilitate the installation of the latch 3 later.

[0029] Specifically, in this embodiment, two spaced-apart protrusions are provided on one side of the first clamping block 1 where the first arc-shaped hole is provided, and a guide groove 11 is formed between the two protrusions.

The positioning block 12 is rotatably arranged inside the positioning groove 22 with the hinge shaft 6 as the center, so that the first clamping block 1 can rotate relative to the second clamping block 2. In addition, some protrusions on the second clamping block 2 where the second arc-shaped hole is provided are provided with two spaced protrusions, and the two protrusions form the positioning groove 22, and the positioning block 12 is installed between the two protrusions.

An arc chamfer is provided on the outer side of the positioning block 12 to avoid interference between the positioning block 12 and the ground of the positioning groove 22 when the first clamping block 1 and the second clamping block 2 rotate relative to each other.

[0035] Preferably, in this embodiment, the chamfer is an arc-shaped chamfer, and the chamfer is coaxially arranged with the hinge axis 6 between the first clamping block 1 and the second clamping block 2 .

[0036] In some embodiments, the first clamping block 1 and the second clamping block 2 may be used as follows: Figure 1 , Figure 2 and Figure 3 See also Figure 1 , Figure 2 and Figure 3 The outer side surfaces of the first clamping block 1 and the second clamping block 2 are provided with anti-rotation surfaces 5 for easy clamping by the clamp. The anti-rotation surfaces 5 are provided on the outer sides of the first clamping block 1 and the second clamping block 2, and when the first clamping block 1 and the second clamping block 2 are in a closed state, the anti-rotation surfaces 5 on the first clamping block 1 and the second clamping block 2 are arranged in parallel with each other, so as to facilitate the use of tools to clamp to the outer sides of the first clamping block 1 and the second clamping block 2 in the later stage, and rotate the first clamping block 1 and the second clamping block 2 around the axis of the thin shaft.

[0037] In some embodiments, the first clamping block 1 and the second clamping block 2 may be used as follows: Figure 3 See the structure shown. Figure 3 When the first clamping block 1 and the second clamping block 2 are closed together, the outer side surfaces of the first clamping block 1 and the second clamping block 2 form a hexagonal structure. When the first clamping block 1 and the second clamping block 2 are closed, the guide holes on the first clamping block 1 and the second clamping block 2 overlap, and the first clamping block 1 and the second clamping block 2 can be fixed together by the fixing member 4. At the same time, the first clamping block 1 and the second clamping block 2 form a structure with a regular hexagonal cross section. It is convenient to use tools to rotate the first clamping block 1 and the second clamping block 2 from multiple angles, which is more convenient for on-site operation.
