Description

Technical Field

[0001] The utility model belongs to the field of screw sleeve quality inspection, and specifically relates to an integrated inspection tool for pre-embedded screw sleeves. Background Art

[0002] During the production process of embedded screw sleeves, it is necessary to inspect the correctness of the size of the internal thread of the embedded screw sleeve, the minor diameter of the internal thread, the coaxiality between the internal thread and the hole, and the boring depth. In the prior art, a measuring tool is required to inspect each indicator, which makes it easy to be messy and lose multiple tools when placed together, and it is also cumbersome to use. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an integrated inspection tool for pre-embedded screw sleeves, so as to realize the inspection of multiple indicators of the screw sleeves.

[0004] The utility model provides an integrated inspection tool for embedded threaded sleeves, comprising a column and a threaded plug arranged at the end of the column, wherein the column is coaxially provided with a cylindrical section 1 from one end close to the threaded plug, and the cylindrical section 1 is used to measure the correctness of the minor diameter of the internal thread.

[0005] Optionally, a second cylindrical section is further provided on the cylinder, and the second cylindrical section is coaxial with the cylindrical section, and the second cylindrical section cooperates with the inner hole of the embedded screw sleeve to determine the coaxiality of the internal thread and the inner hole.

[0006] Optionally, a cylindrical end three is arranged between the cylindrical section one and the cylindrical section two, the diameter of the cylindrical end three is larger than that of the cylindrical end one, and the end of the cylindrical end three is used to abut the transition between the internal thread and the inner hole.

[0007] Optionally, the diameter of the cylindrical end two is greater than the diameter of the cylindrical end three, and the cylindrical end three is marked with a number.

[0008] Optionally, an annular mark is provided on the column for calibrating the boring depth of the embedded screw sleeve.

[0009] Optionally, the distance between the annular mark and the end of the cylinder away from the threaded plug is 4-12 cm.

[0010] Optionally, the annular mark is an annular groove or a laser marking mark.

[0011] Optionally, a through hole is transversely opened at one end of the column away from the threaded plug.

[0012] Optionally, the diameter of the through hole is one third to one half of the maximum diameter of the column.

[0013] Optionally, the distance between the center of the through hole and the end of the column away from the threaded plug is 1.5-3 cm.

[0014] The beneficial effect of the utility model is that the threaded plug is operated and rotated after passing through the inner hole of the embedded screw sleeve. When the threaded plug can smoothly mesh with the inner thread of the embedded screw sleeve, the size of the inner thread of the embedded screw sleeve is qualified. If it cannot mesh smoothly, it indicates that the size of the inner thread of the embedded screw sleeve is unqualified, and there is no need to check other indicators. In the process of meshing the threaded plug with the inner thread of the embedded screw sleeve, the cylindrical section 1 gradually enters the inner thread hole of the embedded screw sleeve. If the minor diameter of the inner thread meets the design standard, the cylindrical section 1 can enter smoothly, otherwise it will be blocked, so that the integrated inspection tool can realize a one-time inspection of the size and minor diameter of the inner thread of the embedded screw sleeve, reduces the measuring tools, is not easy to be messy and lost during use, and simplifies the inspection process.

DETAILED DESCRIPTION

[0019] like Figure 1-3 As shown, the utility model provides an integrated inspection tool for embedded threaded sleeves, including a column 10 and a threaded plug 20 arranged at the end of the column 10, and the column 10 is coaxially provided with a cylindrical section 101 from one end close to the threaded plug 20, and the cylindrical section 101 is used to measure the correctness of the minor diameter of the internal thread.

[0020] Compared with the prior art, the utility model provides an integrated inspection tool for the embedded screw sleeve, in which the threaded plug 20 is operated and rotated after passing through the inner hole 1.2 of the embedded screw sleeve. When the threaded plug 20 can smoothly mesh with the inner thread 1.3 of the embedded screw sleeve, the size of the inner thread 1.3 of the embedded screw sleeve is qualified. If it cannot mesh smoothly, it indicates that the size of the inner thread 1.3 of the embedded screw sleeve is unqualified, and there is no need to inspect other indicators. In the process of the threaded plug 20 meshing with the inner thread 1.3 of the embedded screw sleeve, the cylindrical section 101 gradually enters the hole of the inner thread 1.3 of the embedded screw sleeve. If the minor diameter of the inner thread meets the design standard, the cylindrical section 101 can enter smoothly, otherwise it will be blocked, so that the integrated inspection tool can realize a one-time inspection of the size and minor diameter of the inner thread 1.3 of the embedded screw sleeve, reduce the measuring tools, and is not easy to be messy and lost during use, and simplifies the inspection process.

[0021] Please note that Figure 3 The embedded screw sleeve comprises an embedded screw sleeve external thread 1.1, an embedded screw sleeve inner hole 1.2 and an embedded screw sleeve internal thread 1.3.

[0022] In one embodiment, a second cylindrical section 102 is further provided on the column 10. The second cylindrical section 102 is coaxial with the first cylindrical section 101. The second cylindrical section 102 cooperates with the inner hole 1.2 of the embedded screw sleeve to determine the coaxiality of the inner thread 1.3 of the embedded screw sleeve and the inner hole 1.2 of the embedded screw sleeve. Specifically, when the threaded plug 20 and the first cylindrical section 101 are operated for inspection, the second cylindrical section 102 simultaneously inspects the coaxiality of the inner thread 1.3 of the embedded screw sleeve and the inner hole 1.2 of the embedded screw sleeve. If it meets the design standard, it can be smoothly inserted and judged as qualified. If there is a large deviation, it cannot be smoothly inserted and is judged as unqualified.

[0023] In one embodiment, the cylindrical end 3 is arranged between the cylindrical segment 1 101 and the cylindrical segment 2 102, the diameter of the cylindrical end 3 is larger than the cylindrical end 1, and the end of the cylindrical end 3 is used to abut the transition between the embedded screw sleeve internal thread 1.3 and the embedded screw sleeve inner hole 1.2. Specifically, the cylindrical segment 1 101, the cylindrical segment 3 103 and the cylindrical segment 2 102 are successively distributed and machined on a cylinder 10, and the cylindrical segment 1 101 and the cylindrical segment 3 103 are transitioned at a right angle.

[0024] In one embodiment, the diameter of the cylindrical end two is greater than the diameter of the cylindrical end three, and a number is marked on the cylindrical end three. Specifically, the number is used to indicate which specification of the screw sleeve the integrated inspection fixture is inspecting, and the number is machine engraved or laser marked.

[0025] In one embodiment, an annular mark 104 is provided on the column 10 for calibrating the boring depth of the embedded screw sleeve. Specifically, when the threaded plug 20 is in place, the annular mark 104 shows whether it is flush with the end face of the embedded screw sleeve to judge whether the boring depth is qualified.

[0026] In one embodiment, the distance between the annular mark 104 and the end of the column 10 away from the threaded plug 20 is 4-12 cm. The specific parameters need to be selected according to the threaded sleeves of different specifications. The purpose is to make the integrated inspection fixture easy to pick up and operate.

[0027] In one embodiment, the annular mark 104 is an annular groove or a laser marking mark.

[0028] In one embodiment, a through hole 105 is transversely opened at one end of the column 10 away from the threaded plug 20. This makes it easy to insert a tool into the through hole 105 to rotate the integrated gauge and to store and fix it in a tool box to avoid damage caused by collision during movement.

[0029] In one embodiment, the diameter of the through hole 105 is one third to one half of the maximum diameter of the column 10 . With this design, the auxiliary rotating tool can meet the strength requirements, is easy to operate, and is not prone to deformation of the through hole 105 .

[0030] In one embodiment, the distance between the center of the through hole 105 and the end of the cylinder 10 away from the threaded plug 20 is 1.5-3 cm, so that the auxiliary rotating tool inserted into the through hole 105 has a suitable distance from the annular mark 104 .
