The profile dimension B of the steel wire thread insert is the difference between the pitch diameter of the internal thread for the steel wire thread insert to be installed and the pitch diameter of the internal thread formed after the steel wire thread insert is installed, and is the most important structural dimension of the steel wire thread insert, and has direct influence on the matching precision and the connection strength of the steel wire thread insert. Therefore, the standard of the wire thread insert at home and abroad prescribes very tight tolerance for the profile dimension B of the wire thread insert and requires inspection.
When the steel wire thread insert is detected according to the standard specification, the steel wire thread insert is required to be installed in the thread ring gauge, but when the special installation tool is used for screwing the steel wire thread insert into the thread ring gauge, the situation that the external angle of the diamond-shaped section of the steel wire thread insert cannot be tightly attached to the internal thread of the thread ring gauge due to the fact that the installation tool cannot be completely matched with the thread ring gauge often occurs, the internal thread of the thread ring gauge and the installation tool are damaged when the test fails, and difficulty and challenges are brought to the test.
In combination with the actual situation, the embodiment of the application provides the fixing assembly of the steel wire thread insert, the special fixing assembly is designed to assist in fixing the steel wire thread insert, and the deep hole which is suitable for the installation tool and the thread ring gauge is designed, so that the installation tool and the thread ring gauge can be completely fit together through the fixing assembly, the external angle of the diamond-shaped section of the steel wire thread insert is tightly attached to the internal thread of the thread ring gauge during detection, and the comprehensive inspection detection efficiency and the test success rate of the profile of the steel wire thread insert are improved.
As shown in fig. 4, a schematic cross-sectional structure of a fixing assembly of a wire thread insert according to the present application is provided, where the fixing assembly of a wire thread insert includes: a module body 1 and a fixing through hole 2 penetrating the module body 1; the fixed through hole 2 comprises a first deep hole 21 and a second deep hole 22 which are communicated with each other, and the central axis of the first deep hole 21 is coincident with the central axis of the second deep hole 22; the first deep hole 21 corresponds in size to the mounting tool of the wire thread insert to be inspected, and the second deep hole 22 corresponds in size to the threaded ring gauge corresponding to the wire thread insert, so that the wire thread insert can be fixed by the fixing assembly when being inspected by the mounting tool and the threaded ring gauge.
In this embodiment, the component body 1 is a body structure of the fixing component, which may be a cylindrical structure, a rectangular structure, or a shape structure specifically designed according to a specific application scenario. One face of the assembly body 1 is used for corresponding to an installation tool of the wire thread insert, and the other face opposite to the one face is used for corresponding to a threaded ring gauge. Then, the assembly main body 1 is internally provided with a fixing through hole 2 in a penetrating way, the fixing through hole 2 is mainly used for enabling one end of the installation tool for clamping the steel wire thread insert to be placed into the assembly main body 1 through one end of the fixing through hole 2, and the threaded hole of the threaded ring gauge for bearing or fixing the steel wire thread insert extends into the assembly main body 1, so that the steel wire thread insert can be internally installed into the threaded hole of the threaded ring gauge in the assembly main body 1, and the position of the steel wire thread insert and the relative position of the installation tool and the threaded ring gauge are fixed through the assembly main body 1, namely the fixing through hole 2. Thereafter, the fixing through hole 2 is divided into a first deep hole 21 and a second deep hole 22. The first deep hole 21 corresponds to the mounting tool, and the size of the first deep hole is matched with the mounting tool, so that the mounting opening of the clamping wire thread insert of the mounting tool can be placed into the first deep hole 21 when the wire thread insert is mounted. The second deep hole 22 corresponds to a threaded ring gauge, and is sized to fit into a threaded hole of the threaded ring gauge for carrying or securing the wire thread insert, such that a portion of the threaded hole of the threaded ring gauge can extend into the second deep hole 22 when the wire thread insert is installed. And then, the central axis of the first deep hole is coincident with the central axis of the second deep hole, so that the installation tool extending into the first deep hole and the center of the threaded ring gauge are also mutually corresponding, and the positions of the installation tool and the threaded ring gauge are accurately and precisely fixed. Finally, the steel wire thread insert can be accurately and tightly attached when being mounted to the threaded ring gauge.
In a specific application scenario, the fixing component is a cylindrical component, and the component main body 1 and the first deep hole 21 and the second deep hole 22 therein are both cylindrical, as shown in fig. 5, and is a schematic three-dimensional structure of the fixing component of the wire thread insert. In fig. 5, 3 dimensions are marked, wherein dimension a is the diameter dimension of the first deep hole 21, which corresponds to the dimension of the mounting opening of the mounting tool for fixing the wire thread insert; the dimension b is the diameter dimension of the second deep hole 22, which corresponds to the dimension of the threaded hole of the threaded ring gauge for fixing the wire thread insert; the dimension c is the diameter dimension of the assembly body 1, i.e. the diameter dimension of the fastening assembly, which can generally be designed to be 4 to 10 mm larger than the dimension b. Then, as shown in fig. 6, a schematic diagram of the detection of the wire thread insert by the cooperation of the fixing component, the installation tool and the threaded ring gauge is shown. It can be seen that one surface of the component main body 1 of the fixing component corresponds to the mounting tool, the opposite surface corresponds to the threaded ring gauge, the mounting port of the mounting tool is inserted into the first deep hole 21 of the fixing component, and the threaded hole of the threaded ring gauge extends into the second deep hole 22, so that accurate butt joint of the two is completed, and the steel wire threaded sleeve clamped at the mounting port is accurately mounted into the threaded hole of the threaded ring gauge. The wire thread insert to be tested, the installation tool and the central line of the thread ring gauge are fixed on the same straight line through the fixing component, so that the installation tool can be vertically screwed into the thread ring gauge without deviation. And finally, the steel wire thread insert is smoothly screwed into the threaded ring gauge, and then the profile size B of the steel wire thread insert is detected through the threaded plug gauges such as a go gauge, a no-go gauge and the like.
From the above, it can be seen that the fixing assembly of the wire thread insert provided by the present application comprises: the assembly main body and the fixing through hole penetrating the assembly main body; the fixed through hole comprises a first deep hole and a second deep hole which are communicated with each other, and the central axis of the first deep hole is coincident with the central axis of the second deep hole; the size of the first deep hole corresponds to the size of the installation tool of the steel wire thread insert to be detected, and the size of the second deep hole corresponds to the size of the threaded ring gauge corresponding to the steel wire thread insert, so that the steel wire thread insert can be fixed through the fixing component when being detected through the installation tool and the threaded ring gauge. According to the application, the special fixing component is designed to assist in fixing the steel wire threaded sleeve, and the deep hole which is matched with the mounting tool and the threaded ring gauge is designed, so that the mounting tool and the threaded ring gauge can be completely matched together through the fixing component, the external angle of the diamond-shaped section of the steel wire threaded sleeve is tightly attached to the internal thread of the threaded ring gauge during detection, and the comprehensive inspection detection efficiency and the test success rate of the steel wire threaded sleeve profile are improved.
In an alternative embodiment, as shown in fig. 4, a boss 11 is provided at one side of the assembly body 1, the boss 11 corresponds to the installation tool, and the first deep hole 21 of the fixing through hole 2 passes through the boss 11. Therefore, the installation tool is better received by the protruding part, so that the installation opening of the installation tool can be more surely placed in the first deep hole 21.
In this embodiment, since the wire thread insert itself may be smaller, the mounting opening of the corresponding mounting tool is also necessarily smaller, and more support may be required for the mounting tool to be stable, and further, the protruding portion is designed on the assembly body 1 for receiving the mounting tool, so that the mounting tool can be more surely and stably placed in the first deep hole 21.
In an alternative embodiment, as shown in fig. 4 and 5, the first deep hole 21 and the second deep hole 22 are cylindrical deep holes.
In an alternative embodiment, the diameter of the first deep hole 21 corresponds to the size of the mounting hole for the mounting tool to secure the wire thread insert; the diameter of the second deep hole 22 corresponds to the size of the threaded hole of the threaded ring gauge for fixing the wire thread insert.
In this embodiment, since the first deep hole 21 is used for receiving a mounting tool, the second deep hole 22 is used for receiving a threaded ring gauge, and the corresponding mounting tools may be different according to different wire thread inserts, so that in a specific application scenario, the diameter a of the first deep hole 21 corresponds to the size of the mounting hole for fixing the wire thread insert by the mounting tool, and the diameter a of the first deep hole 21 may be changed according to different wire thread insert specifications. The diameter b of the second deep hole 22 corresponds to the size of the threaded hole of the threaded ring gauge for fixing the wire thread insert, which may also be changed with a change in the gauge of the wire thread insert.
In an alternative embodiment, as shown in fig. 4 and 5, the diameter of the first recess 21 is smaller than the diameter of the second recess 22.
In this embodiment, the size of the typical threaded ring gauge is generally greater than the size of the installation tool, and accordingly, the diameter of the second deep hole 22 is generally greater than the diameter of the first deep hole 21.
In an alternative embodiment, as shown in fig. 4 and 6, the protruding portion 11 is a cylindrical protrusion. Thus better corresponding to and receiving the installation tool.
In an alternative embodiment, as shown in fig. 4 and 6, the diameter of the boss 11 is adapted to the installation tool.

In an alternative embodiment, as shown in fig. 4 and 5, the diameter of the assembly body 1 is the size of the second deep hole 22 plus 4 to 10 mm.
In this embodiment, the diameter of the main body of the assembly is the size of the fixing assembly, and the larger the size and thickness of the fixing assembly in the whole fixing process, the higher the stability of the fixing assembly, but if the thickness is too large, the larger the weight of the fixing assembly is, and the larger the size is not beneficial to picking and placing. Thereafter, since the size of the second deep hole 22 is generally larger than that of the first deep hole, the size of the module body 1 may be determined according to the size of the second deep hole 22, which may be generally 4 to 10 mm larger than that of the second deep hole 22.
