[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-4 As shown, this utility model relates to a positioning pin, which is applied to the herringbone arm of a spinning machine. It includes a positioning pin body 1, a flat surface 2 in the middle of the positioning pin body 1, and an internally threaded hole 3 on the flat surface 2. A screw is used to pass through the internally threaded hole 3 and fix the pin to the herringbone arm of the spinning machine. The model also includes:

[0025] A baffle 4 is disposed at one end of the positioning pin body 1 and is used to limit the positioning pin body 1 on the herringbone arm of the spinning machine.

[0026] The slot 5 is disposed at the other end of the positioning pin body 1 along the length direction of the positioning pin body 1;

[0027] The retaining spring fixing unit includes a retaining spring 6 adapted to be disposed in the retaining groove 5 and a fastening bolt 7 threadedly disposed on the positioning pin body 1 and close to the retaining spring 6. The retaining spring 6 is used to limit the relative position of the spinning machine's herringbone arm and the positioning pin body 1, and the fastening bolt 7 is used to limit the relative position of the retaining spring 6 and the positioning pin body 1.

[0028] In practice, by machining the plane 2 at the center of the circumference of the positioning pin body 1 and machining the internal threaded hole 3 through the plane 2, the positioning pin body 1 can be inserted through the positioning pin hole on the herringbone arm of the spinning machine and then fastened to the herringbone arm of the spinning machine with fastening screws. At the same time, with the cooperation of the baffle 4 welded to one end of the positioning pin body 1 and the snap ring fixing unit installed at the other end of the positioning pin body 1, the displacement of the sleeve frame on the herringbone arm installed in the length direction on the positioning pin body 1 is restricted, which plays a double insurance fixing function and avoids equipment damage caused by the positioning pin on the herringbone arm falling off.

[0029] Furthermore, the groove 5 machined on the other end of the positioning pin body 1 relative to the baffle 4 can be adapted to the combined snap ring 6, and under the thread compression of the fastening bolt 7, it can effectively limit the herringbone arm connected in the length direction on the positioning pin body 1, preventing the herringbone arm from moving along the length direction of the positioning pin body 1.

[0030] In an embodiment, two limiting strips 8 are symmetrically arranged in the card slot 5, and two slot holes 61 are symmetrically arranged on the card spring 6 for the limiting strips 8 to pass through.

[0031] The slot holes 61 are transversely arranged through the inner and outer walls of the card spring 6. In this way, by symmetrically arranging two limiting strips 8 on the outside of the card slot 5, and symmetrically turning two slot holes 61 on the card spring 6, the limiting strips 8 and the slot holes 61 are adapted to pass through, which can limit the card spring 6 fixed in the card slot 5 in a plane, preventing the card spring 6 from loosening and falling off in the card slot 5.

[0032] It should be noted that the limiting strip 8 is made of spring steel, which can be elastically deformed when an external force is applied, so that the included angle of the limiting strip 8 on the side of the card slot 5 increases.

[0033] In an embodiment, the limiting strip 8 swings in the circumferential direction in the card slot 5, and the slot wall of the card slot 5 is provided with a spring 81 for resetting the position of the limiting strip 8. In this way, by welding a section of spring 81 with an arc structure on the slot wall of the card slot 5, the spring 81 can be used to restore the limiting strip 8 to the initial included angle after the external force disappears, so that the card spring 6 is stably fixed in the card slot 5.

[0034] In an embodiment, the limiting strip 8 is composed of an arc segment and a ball end, and the ball end extends through the inside to the outside of the slot hole 61 when the limiting strip 8 is placed inside the slot hole 61. In this way, the limiting strip 8 is integrally formed by the arc segment and the ball end, and is made of spring steel material, and the outer diameter of the ball end is smaller than or equal to the inner width of the slot hole 61, so that the ball end at the top of the limiting strip 8 smoothly passes through the slot hole 61.

[0035] In an embodiment, an inner threaded groove 9 adapted to install the fastening bolt 7 is arranged on the end face of the positioning pin body 1 close to the fastening bolt 7. In this way, by turning the inner threaded groove 9 on one side of the positioning pin body 1, the fastening bolt 7 can be fixed on the side of the positioning pin body 1 by the engagement of the threads, so as to achieve the axial fixation of the support on the herringbone arm of the spinning machine.

[0036] In an embodiment, the inner side of the baffle 4 is provided with a circular truncated cone shape. In this way, the circular truncated cone shape turned on the inner side of the baffle 4 makes the uniformity of the support connected on the herringbone arm of the spinning machine on this side, which helps to maintain the stability of the structure.

[0037] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
