[0002] In the process of product production and use, it is often necessary to assemble and disassemble two workpieces, especially for special annular or spherical workpieces. The sealing requirements of the connection section of the two workpieces often require a smaller clearance fit, and the fit tolerance gap is not greater than 0.05mm. In the case of a small fit gap, the circumference needs to be uniformly pushed or ejected during the assembly process to complete the assembly or disassembly. However, this special workpiece does not allow for extra propulsion devices or holes on the outside, so there are no force points during assembly and disassembly, and it is difficult to apply uniform tension or thrust to complete the assembly and disassembly between workpieces. Therefore, an annular fastening and disassembly tool is designed to solve the problem of difficult assembly during the assembly of special annular or spherical workpieces and improve production efficiency.

[0005] Furthermore, the metal ring is used to connect the annular component and the spherical component, and can also be used to connect two annular components or two spherical components.

[0006] Furthermore, the connection seat is arranged at the end of the metal half ring.

[0007] Furthermore, the connecting seat connects the two metal half rings into a set of metal rings through bolts and nuts.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0023] See also Figure 1-5 To illustrate the present embodiment, a tool for connecting components comprises two groups of metal rings, each group of metal rings comprises two metal half rings 1, the two metal half rings 1 are connected via a connecting seat 2, the inner surfaces of the two groups of metal rings are respectively fitted with the outer surfaces of the interface positions of the first component 7 and the second component 8, the metal rings are symmetrically provided with positive and negative thread bolt holes 3, the positive and negative thread bolt rods 6 are provided in the positive and negative thread bolt holes 3, the two groups of metal rings are connected via the positive and negative thread bolt rods 6, the first component 7 and the second component 8 can be fastened by the positive and negative thread pressure bolt rods 6 rotating forward, and the first component 7 and the second component 8 can be disassembled by the reverse rotation of the positive and negative thread bolt rods 6, the metal rings are provided with eight adjustment holes along the circumferential direction, the eight adjustment holes include four fastening holes 5 and four ejection holes 4, the adjustment holes are used for fine-tuning the time distance of fastening and disassembly when the two components are connected.

[0024] The two metal half rings 1 are connected to form a group of metal rings through a connecting seat 2, and another group of metal rings are connected in the same way, so that the two groups of metal rings are respectively fitted with the outer surfaces of the interfaces of the first component 7 and the second component 8. When installing the two groups of metal rings, ensure that the positive and negative thread bolt holes 3 of the two groups of metal rings are symmetrical. When the two components are fastened, first use the positive and negative thread bolt rod 6 to rotate forward and tighten it to the interface of the two components to ensure that they are not separated after the external force is removed. Then, the four fastening holes 5 are tightened simultaneously through four screws, so that the two components are tightly connected, and the gap between the two connected components is ensured to be within the design tolerance range. If the connecting seats 2 on the two groups of metal rings are tightly fitted during the fastening process and cannot be further fastened, it is only necessary to disassemble the metal rings and adjust the two groups of metal rings so that a distance is left between the two groups of metal rings, and then continue to tighten. When disassembling, remove the screws on the four fastening holes 5, reverse the positive and negative thread bolt rod 6, and screw on the four ejection holes 4 at the same time. The two components are separated by the ejection force between the screw and the metal half ring 1, and finally disassembly is achieved.

[0025] The metal ring is used to connect the annular component and the spherical component, and can also be used to connect two annular components or two spherical components.

[0026] The connecting seat 2 is arranged at the end of the metal half ring 1 .

[0027] The connection seat 2 connects the two metal half rings 1 into a set of metal rings through bolts and nuts, and the inner surface of the metal ring is fastened to the outer surface of the component by tightening the bolts and nuts.

[0028] The forward and reverse thread bolt holes 3 are arranged at the center of the metal half ring 1. When installing, the forward and reverse thread bolt holes 3 of the two groups of metal rings are in the same position. The two components are connected and tightened by the forward and reverse thread bolt rod 6, and the two components are separated by the reverse rotation of the forward and reverse thread bolt rod 6.

[0029] Threads are arranged inside the eight adjustment holes, and bolts are arranged in the adjustment holes through the threads.

[0030] The ejection holes 4 and the fastening holes 5 are arranged alternately.

[0031] The fastening holes 5 on the two groups of metal rings are symmetrically arranged, and the four fastening holes 5 are evenly distributed along the circumferential direction of the metal ring to ensure uniform circumferential force during fastening.

[0032] The ejection holes 4 on the two groups of metal rings are staggered, and the four ejection holes 4 are evenly distributed along the circumferential direction of the metallization to ensure that the circumference is subjected to uniform force during disassembly and ejection.

[0033] The above-mentioned tooling for connection effectively solves the problem of difficult assembly during the assembly of special annular or spherical workpieces, and improves production efficiency. The tooling can be used to achieve assembly and disassembly when no extra propulsion devices or holes are allowed on the outside of the special workpiece. The fastening holes 5 and the ejection holes 4 on the tooling can be used to apply uniform tension or uniform thrust to complete the assembly and disassembly between the workpieces, while ensuring that the two annular or spherical parts are not damaged during the assembly or disassembly process. For connectors that require a small matching tolerance gap, the fastening holes 5 and the ejection holes 4 of the workpiece can be used to fine-tune the gap between the two components until the gap between the two components is within the design tolerance range.

According to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
