Description

Technical Field

[0001] This application relates to the field of wire drawing machine technology, and in particular to an adaptive positioning rod. Background Technology

[0002] Wire drawing machines are common industrial equipment for metal surface treatment. Their core function is to form specific textures on the material surface through physical grinding and to simultaneously treat surface defects.

[0003] During use, the output shaft drives the wire drawing shaft to rotate to achieve the grinding operation. When facing different working scenarios, it is necessary to switch to different specifications of wire drawing wheels. Since the inner hole (i.e., insertion hole and positioning groove) of different specifications of wire drawing wheels is not uniform, the traditional positioning rod cannot be adjusted according to the size of the inner hole of the wire drawing wheel, resulting in large differences in machine vibration value when using different wire drawing wheels, which affects the grinding effect.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides an adaptive positioning rod to solve one of the above-mentioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is: an adaptive positioning rod, including: an output shaft and a drawing wheel. The drawing wheel has a insertion hole at its center, and positioning grooves are formed on both sides of the insertion hole. The output shaft has mounting grooves on both sides. A positioning rod is fixed in the mounting groove. The shapes of the output shaft and the positioning rod are respectively matched with the shapes of the insertion hole and the mounting groove. An opening groove is formed on the positioning rod. A limiting groove is formed on one side of the opening groove. A spring piece is fixed at the bottom of the opening groove. The first end of the spring piece is fixed to one end of the opening groove, and the second end is movable and limited in the limiting groove. An arc-shaped protrusion is formed in the middle of the spring piece. When the positioning rod is inserted into the mounting groove, the arc-shaped protrusion abuts against the bottom of the mounting groove, thereby eliminating the gap between the drawing wheel and the output shaft.

[0007] In some embodiments, the limiting groove communicates with the opening groove, and the bottom surfaces of the limiting groove and the opening groove are flush. One end of the opening groove is provided with a threaded hole.

[0008] In some embodiments, the first end of the spring is fixed to the bottom of the opening groove by a screw, and the screw is fixed by threaded engagement with a threaded hole.

[0009] In some embodiments, a limiting piece is formed at the second end of the spring piece, and the limiting piece is disposed in the limiting groove. Depending on the pressure applied to the arc-shaped protrusion of the spring piece, the length of the limiting piece extending into the limiting groove is adaptively adjusted.

[0010] In some embodiments, when the output shaft is not assembled with the drawing wheel, the height of the arc-shaped protrusion of the spring is higher than the top of the positioning rod, that is, the arc-shaped protrusion protrudes beyond the positioning rod.

[0011] The beneficial effects of this application are as follows: By adding a spring plate to the positioning rod, when the output shaft and positioning rod are assembled with the drawing wheel, the arc-shaped protrusion on the spring plate is squeezed by the inner wall of the positioning groove, which increases the friction between the drawing wheel and the output shaft, thereby eliminating the gap between the drawing wheel and the output shaft, increasing the stability of the machine, reducing vibration, and the spring plate can also adapt to different specifications of drawing wheels, reducing the precision required for the production and assembly of the output shaft and drawing wheel, and improving the applicability of the drawing machine output shaft.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0020] In the embodiments of this application, please refer to Figure 1-5 As shown, this adaptive positioning rod mainly includes an output shaft 1 and a drawing wheel 2. The drawing wheel 2 has a insertion hole 3 at its shaft center. Positioning grooves 4 are formed on both sides of the insertion hole 3. The output shaft 1 has mounting grooves 5 on both sides. A positioning rod 6 is fixed in the mounting groove 5. The shapes of the output shaft 1 and the positioning rod 6 are respectively matched with the shapes of the insertion hole 3 and the mounting groove 5. An opening groove 7 is formed on the positioning rod 6. A limiting groove 8 is formed on one side of the opening groove 7. A spring piece 9 is fixed at the bottom of the opening groove 7. The first end 901 of the spring piece 9 is fixed to one end of the opening groove 7, and the second end 902 is movable and limited in the limiting groove 8. An arc-shaped protrusion 903 is formed in the middle of the spring piece 9. When the positioning rod 6 is inserted into the mounting groove 5, the arc-shaped protrusion 903 abuts against the bottom of the mounting groove 5, which eliminates the gap between the drawing wheel 2 and the output shaft 1.

[0021] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0022] like Figure 5 As shown, the limiting groove 8 communicates with the opening groove 7, and the bottom surfaces of the limiting groove 8 and the opening groove 7 are flush. One end of the opening groove 7 is provided with a threaded hole 10. The spring piece 9 contacts and presses against the wire drawing wheel 2. One end of the spring piece 9 is further inserted into the limiting groove 8. The limiting groove 8 not only restricts the position of the spring piece 9, but also provides space for the deformation of the spring piece 9.

[0023] Specifically, the first end 901 of the spring piece 9 is fixed to the bottom of the opening groove 7 by a screw 11. The screw 11 is fixed by threaded engagement with the threaded hole 10. The screw 11 passes through the first end 901 of the spring piece 9 and is tightened onto the positioning rod 6.

[0024] like Figure 3As shown, the second end 902 of the spring piece 9 forms a limiting piece 904, which is disposed in the limiting groove 8. Depending on the pressure applied to the arc-shaped protrusion of the spring piece 9, the limiting piece 904 adaptively adjusts its length extending into the limiting groove 8.

[0025] like Figure 4 As shown, when the output shaft 1 is not assembled with the drawing wheel 2, the height of the arc-shaped protrusion 903 of the spring piece 9 is higher than the top of the positioning rod 6, that is, the arc-shaped protrusion 903 protrudes from the positioning rod 6. Therefore, when the output shaft 1 is assembled with the drawing wheel 2, the spring piece 9 will always press against the inner wall of the drawing wheel 2, providing a fastening effect for the assembly of the output shaft 1.

[0026] Specifically, this application connects the output shaft 1 and the drawing wheel 2 by inserting the output shaft 1 and the positioning rod 6 into the insertion hole 3 and the positioning groove 4 respectively. When the output shaft 1 is inserted, the spring piece 9 on the positioning rod 6 can press against the inner wall of the drawing wheel 2, thereby eliminating the gap between the drawing wheel 2 and the output shaft 1, increasing the stability of the machine, reducing vibration, and enabling the output shaft 1 to adapt to drawing wheels 2 of different specifications. It should be noted that the gap between the insertion hole 3 and the output shaft 1 is small, and the spring piece 9 is sufficient to make up for this gap.

Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
