AI Technical Summary
When using large-size taps to tap nylon plate threads, the taps are heavier and the nylon plate material is soft, so the taps can easily cut into the nylon plate. The spiral line produced by the attack does not overlap with the spiral line produced by the head attack, resulting in a malfunction.
A tooling is designed, including a threaded sleeve, threaded pipe and a pressure plate assembly. The threaded sleeve is matched on the threaded pipe through the threaded pipe and the threaded sleeve is pressed on the threaded pipe with the pressure plate assembly to ensure that the threaded sleeve is consistent with the spiral line of the threaded thread on the nylon plate. Then, take out the threaded tube and use a tap to tap the thread from the thread sleeve to ensure the correctness of the thread.
Through this tooling, the occurrence of mists can be effectively avoided, ensuring that the threaded spiral lines on the nylon plate are consistent with the spiral lines attacked by the head attack, and improving the integrity and qualification of the thread.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nylon plate processing, and particularly relates to a tool for tapping large-size threads on a nylon plate by using a tap. Background Art
[0002] The general method of tapping threads is to first use the first tap to tap the threads, and then use the second and third taps to tap the complete threads along the spiral line tapped by the first tap. Generally, taps are divided into first tap, second tap or first tap, second tap, and third tap according to specifications, while large-sized threads not only have first tap, second tap, and third tap, but also four tap, five tap, and six tap. When tapping the threads, each subsequent tap must tap along the spiral line tapped by the first tap, so that a complete and qualified thread can be obtained. After tapping the first tap, when tapping the second tap, third tap, etc., it is necessary to align the spiral line tapped by the first tap. However, due to the large size of the tap itself, when placed on the nylon board, the tap is heavy and the nylon board is soft, so the tap can easily cut into the nylon board, and the spiral line tapped does not overlap with the spiral line tapped by the first tap, resulting in misalignment.
[0003] In view of this, we have developed a tooling that uses a tap to tap large-size threads. Utility Model Content

[0005] As a preferred technical solution, the helical lines of the first external thread and the second external thread are the same.
[0006] As a preferred technical solution, the end face of the threaded sleeve is flush with the surface of the nylon plate.
[0007] As a preferred technical solution, when in use, the center line of the tapped hole of the nylon plate, the center line of the threaded sleeve and the center line of the threaded pipe coincide with each other.
[0008] As a preferred technical solution, the threaded sleeve is a cemented carbide threaded sleeve.
[0009] Technical effect: By connecting the threaded tube with the thread on the nylon plate, fitting the threaded sleeve on the threaded tube, making it flush with the surface of the nylon plate, and then pressing the threaded sleeve, it can be ensured that the spiral lines of the threaded sleeve and the thread on the nylon plate are consistent. At this time, take out the threaded tube, use a tap to tap the thread from the threaded sleeve, which can effectively ensure that the spiral line of the thread on the nylon plate is consistent with the spiral line tapped by the head tap.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0015] The utility model provides a tool for tapping large-size threads on nylon plates using taps in an embodiment, which belongs to nylon plate processing. It is understandable that in the prior art, the general method of tapping threads is to first use a first tap to tap out the threads, and then use a second tap and a third tap to tap out the complete threads along the spiral line tapped out by the first tap. General taps are divided into first tap, second tap or first tap, second tap, and third tap according to specifications, while large-size threads have not only first tap, second tap, and third tap, but also fourth tap, fifth tap, and sixth tap. And each of the following taps must tap along the spiral line tapped out by the first tap when tapping the threads, so that a complete and qualified thread can be obtained. After the first tap, when tapping the second tap, third tap and other threads, it is necessary to align the spiral line produced by the first tap. However, due to the large size of the tap itself, when placed on the nylon plate, the tap is heavy and the nylon plate is soft, which makes the tap easily cut into the nylon plate. The spiral line produced does not overlap with the spiral line produced by the first tap, resulting in misalignment.
[0016] Based on this, how to provide a tooling for tapping large-size threads is a technical problem that needs to be solved urgently.
[0017] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] refer to Figure 1-3 The embodiment of the utility model provides a tool for tapping large-size threads on a nylon plate 1 using a tap, the tool comprising a threaded sleeve 3, a threaded tube 5 and a pressure plate assembly 6 for fixing the threaded sleeve 3 to the nylon plate 1, the pressure plate assembly 6 is located on one side of the threaded sleeve 3, the threaded sleeve 3 is located on the upper side of a tapped hole of the nylon plate 1, the outer side of the threaded tube 5 comprises a first external thread 2 and a second external thread 4, the first external thread 2 cooperates with the internal thread of a tapped hole of the nylon plate 1, and the second external thread 4 cooperates with the internal thread of the threaded sleeve 3.
[0019] When using this tooling, it is first necessary to use a tap to tap a threaded hole in the nylon plate 1 to be processed, screw the threaded tube 5 into the threaded hole on the nylon plate 1, and at the same time, fit the threaded sleeve 3 on the threaded tube 5 and make it flush with the surface of the nylon plate 1, and then use the pressure plate assembly 6 to tighten the threaded sleeve 3 to ensure that the spiral line in the threaded hole of the threaded sleeve 3 is consistent with that in the nylon plate 1. At this time, take out the threaded tube 5, and use the tap to tap the thread down along the threaded sleeve 3 for two, three, four, five times, etc. In the process of tapping the threaded hole of the nylon plate 1, since the tap is tapped downward under the guidance of the threaded sleeve 3, it can effectively ensure that the spiral line in the threaded hole on the nylon plate 1 is consistent with the spiral line tapped by the head tap, and the occurrence of misaligned teeth will not occur.
[0020] In some embodiments, the helical lines of the first external thread 2 and the second external thread 4 are the same.
[0021] In some embodiments, the end surface of the threaded sleeve 3 is flush with the surface of the nylon plate 1 to ensure concentricity.
[0022] In some embodiments, when in use, the center line of the tapped hole of the nylon plate 1, the center line of the threaded sleeve 3 and the center line of the threaded tube 5 coincide with each other to ensure the concentricity of the three.
[0023] In some embodiments, the threaded sleeve 3 is a cemented carbide threaded sleeve 3 .
