[0002] After the cylindrical products are machined, the threaded sleeve needs to be assembled onto the cylindrical parts. However, during the threaded sleeve assembly, the following assembly situations are prone to occur.

[0003] 1. The part is cylindrical and lacks a relatively flat positioning surface. The cylinder can only be placed vertically and then the screw sleeve can be installed from the side. The screw sleeve is small in size and is easy to loosen and fall off during assembly, which is inconvenient to assemble;

[0004] 2. The screw sleeve itself is very small, inconvenient to assemble, not easy to rotate, and low assembly efficiency;

[0005] 3. During the assembly process, there is no limit, clamping, or removal, resulting in low assembly efficiency and difficulty in installation;

[0006] Therefore, a technical solution is currently needed to solve the problem of facilitating assembly and improving efficiency in the mechanical processing and threaded assembly of cylindrical parts. Utility Model Content

[0007] In order to overcome the above-mentioned deficiencies, the inventor of the utility model has continuously reformed and innovated through long-term exploration and attempts, multiple experiments and efforts, and proposed a screw sleeve part assembly tool, which uses the spring of the tool body to expand the tool body, so that the screw sleeve is fixed on the tool body that can be expanded and is mounted on the protrusion. At the same time, the protrusion and the limit step are used for positioning to achieve accurate installation of the screw sleeve on the tool. The operator only needs to hold the tool to install the screw sleeve on the cylindrical part. Holding it tightly so that the tool body is pressed and closed, the screw sleeve can be detached, making it convenient to remove the tool.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is: to provide a screw sleeve part assembly tool. It includes a tool body, a spring, and a tension screw. The tool body is cylindrical, a gap is set in the middle of the cylinder, and the gap penetrates the middle and front of the cylinder so that the tool body becomes a tweezers structure. The front end of the tool body is set as a cone surface and a protrusion for installing the screw sleeve is set at the front end. A spring hole is set perpendicular to the gap surface, and the spring hole penetrates at least half of the tool body. The spring is installed in the spring hole so that the tool body is initially in an open structure. The tension screw is used to block the spring in the spring hole.

[0014] According to the screw sleeve part assembly tool described in the utility model, a further preferred technical solution is: a limiting step for positioning the screw sleeve and preventing the screw sleeve from rotating is provided on the protrusion, and the position of the limiting step corresponds to the position of the notch on the screw sleeve.

[0015] According to the screw sleeve part assembly tool described in the utility model, a further preferred technical solution is that the limiting steps are arranged around the protrusion and the number of the limiting steps is more than one.

[0016] Compared with the prior art, the technical solution of the utility model has the following advantages / benefits:

[0017] 1. Use the spring of the tooling body to expand the tooling body so that the screw sleeve can be fixed on the tooling body that is mounted on the protrusion and expanded. At the same time, use the protrusion and the limit step for positioning to achieve accurate installation of the screw sleeve on the tooling. The operator only needs to hold the tooling to install the screw sleeve on the cylindrical part.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0028] Example:

[0029] like Figure 1-Figure 5As shown, a screw sleeve 4 parts assembly tool comprises a tool body 1, a spring 2, and a tension screw 3. The tool body 1 is cylindrical, and a slit 101 is arranged in the middle of the cylinder. The slit 101 penetrates the middle and front of the cylinder so that the tool body 1 becomes a tweezer structure. The front end of the tool body 1 is arranged as a conical surface and a protrusion 102 for installing the screw sleeve 4 is arranged at the front end. A spring 2 hole is arranged perpendicular to the surface of the slit 101. The spring 2 hole penetrates at least half of the tool body 1. The spring 2 is installed in the spring 2 hole so that the tool body 1 is initially in an open structure. The tension screw 3 is used to block the spring 2 in the spring 2 hole. At the same time, the height adjustment of the tension screw 3 can also adjust the rebound force of the spring 2, so that the pinching pressure is adjusted to a suitable range.

[0030] The diameter of the tool body 1 is 8cm-12cm. In fact, the diameter of the tool body 1 is a diameter that is convenient for the operator to hold. It only needs to be able to hold and pinch, and there is no strict restriction. Furthermore, it is set as a cylinder for ease of use, and only a tweezers structure needs to be formed.

[0031] The middle part of the tool body 1 is provided with anti-skid patterns, which makes it easier for operators to hold and prevents it from slipping when pinching.

[0032] The tail of the tool body 1 is set to be hemispherical, which can be more beautiful while avoiding sharp edges and corners, making it safer to use.

[0033] The tail of the slit 101 is configured to be in a teardrop shape to increase elasticity, which is to reduce the pressure required to pinch the tool body 1 and also to increase the elasticity of the tool body 1 .

[0034] The protrusion 102 for installing the screw sleeve 4 is bisected by the gap 101 located in the tool body 1. The protrusion 102 is cylindrical and the outer diameter matches the inner diameter of the screw sleeve 4, that is, the shape of the protrusion 102 is set corresponding to the shape of the screw sleeve 4. When in use, the screw sleeve 4 is mounted on the protrusion 102, and the elasticity of the tool body 1 and the spring 2 is used to expand the protrusion 102 (the protrusion 102 is divided into two halves), thereby fixing the screw sleeve 4.

[0035] A limiting step 103 for positioning the screw sleeve 4 and preventing the screw sleeve 4 from rotating is arranged on the protrusion 102 , and the position of the limiting step 103 corresponds to the position of the notch on the screw sleeve 4 .

[0036] The limiting steps 103 are arranged around the protrusion 102 and there are more than one of them. It is best to set them symmetrically to facilitate the rotation of the screw sleeve 4.

[0037] By using the tooling of the utility model, the screw sleeve can be conveniently installed on the cylindrical part 5, and the installation of a small screw sleeve is particularly convenient.
