[0014] It is easy to understand that according to the technical scheme of the utility model, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the utility model. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical scheme of the utility model, and should not be regarded as the whole or as a limitation or restriction on the technical scheme of the utility model.

[0015] A positioning device for the bolt counting and machining process as shown in Figure 1 The outer sleeve 3 is a cylindrical or cubic structure, and a movable groove 5 is formed in the length direction of the outer sleeve 3. One end of the ejector rod 1 is located in the movable groove 5, and the other end penetrates one side of the length direction of the outer sleeve 3. The ejector rod 1 can reciprocate in the movable groove 5 of the outer sleeve 3 without sliding out of the outer sleeve 3. A base 4 is fixedly arranged on the other side of the outer sleeve 3, and a spring 2 is arranged in the movable groove 5. One end of the spring 2 is in contact with the ejector rod 1, and the other end is in contact with the inner wall of the movable groove 5. By compressing the spring 2, a ejecting force can be provided for the ejector rod 1, so as to provide a ejecting force for the head of the bolt and press it tightly, thereby assisting the machining process of the bolt rod.

[0016] The top rod 1 comprises a rod body segment 6 and a limiting segment 7, the limiting segment 7 is located in the movable slot 5, the rod body segment 6 extends out of the sleeve 3, and one end of the spring 2 is in contact with the limiting segment 7. A limiting block 8 is arranged in the movable slot 5, the inner diameter of the limiting block 8 is smaller than the outer diameter of the limiting segment 7 and is not smaller than the outer diameter of the rod body segment 6, which provides conditions for the reciprocating movement of the top rod 1 in the movable slot 5, the limiting block 8 can be fixedly arranged at one end of the movable slot 5 connected to the outside, which can maximize the movement range of the top rod 1 in the movable slot 5.

[0017] An adjusting segment 9 is arranged in the sleeve 3, the width of the adjusting segment 9 is greater than the width of the movable slot 5, and the adjusting segment 9 is coaxially arranged with the movable slot 5, an internal thread is arranged on the inner wall of the adjusting segment 9, an external thread is arranged on the upper segment outer edge surface of the base 4, and the base 4 and the sleeve 3 (the adjusting segment 9) are fixed by thread cooperation. A circular groove with the same width as the movable slot 5 is arranged at the center position of the upper segment of the base 4, and one end of the spring 2 is in contact with the bottom end of the circular groove arranged on the base 4. It is worth noting that the length of the adjusting segment 9 is greater than the upper segment of the base 4, so that the upper segment of the base 4 can be screwed into the adjusting segment 9, thereby further reducing the length of the spring 2 in the movable slot 5, thereby providing greater ejection force for the top rod 1.

[0018] In actual use, the base 4 of the positioning device is fixed on the numerical control machine tool, the top rod 1 ejects the bolt head, and the spring 2 in the positioning device forms an ejection force on the bolt at any time through the top rod 1, so that the length difference caused by the displacement of the bolt during the machining process is avoided. After the bolt product completes the numerical machining process, the machined bolt can be easily taken out through the positioning device.

[0019] The technical scope of the utility model is not limited to the content in the foregoing description, and those skilled in the art can make various deformations and modifications to the foregoing embodiments without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
