[0027] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0028] This application discloses an automatic feeding and stacking auxiliary device for spring coils 3, including a guide rod 1, a receiving rod 2 located below and connected to the guide rod 1, and a support assembly located below and connected to the receiving rod 2. The guide rod 1 has a circular cross-section, and the spring coil 3 is a C-shaped spring coil 3 with a notch. The top of the guide rod 1 has a neck 4, the outer diameter of which is smaller than the outer diameter of the guide rod 1. The neck 4 transitions to the guide rod 1 through a guide slope 5. To ensure that the notch of the C-shaped spring coil 3 is consistent, a limiting protrusion 6 is formed on the side of the guide rod 1 to restrict the rotation of the spring coil 3. When the spring coil 3 is on the guide rod 1, its notch corresponds exactly to the limiting protrusion 6. Furthermore, a guide block 7 is also formed on the top of the limiting protrusion 6. One side of the guide block 7 is a slope, and the guide block 7 cooperates with the guide slope 5 to allow the C-shaped spring coil 3 to fit into the guide rod 1 with the limiting protrusion 6.

[0029] The guide rod 1 has a first insertion hole 8 at its bottom. Due to the presence of the limiting protrusion 6, the first insertion hole 8 also extends into the limiting protrusion 6, thus the shape of the first insertion hole 8 is similar to a U-shaped hole. The receiving rod 2 has a first insertion part 9 at its top, which is inserted into the first insertion hole 8. The shape and size of the first insertion part 9 are the same as those of the first insertion hole 8. The receiving rod 2 has a second insertion hole 22 at its lower end. Specifically, the receiving rod 2 also has the same limiting protrusion 6 as the guide rod 1, and the cross-sections of the receiving rod 2 and the guide rod 1 are the same. A limiting plate 10 is fixed at the bottom of the receiving rod 2.

[0030] To facilitate the installation of the guide rod 1, a mounting rod 11 for connection with the spring machine 12 is fixed on the guide rod 1. Specifically, the mounting rod 11 is a U-shaped rod and is fixed to the side wall of the limiting protrusion 6, so as not to affect the sliding of the spring coil 3 on the guide rod 1. The mounting rod 11 can be directly welded to the spring machine 12. The mounting rod 11 is generally fixed by a clamp.

[0031] The support assembly includes a lower base 13, a movable rod 14 inserted into the lower base 13 and movable relative to the lower base 13, an upper base 15 fixed on the movable rod 14, and a compression spring 16 sleeved on the movable rod 14 with its two ends connected to the upper base 15 and the lower base 13 respectively (the two ends of the compression spring 16 can be fixed or abutted). A receiving rod 2 is inserted into the upper base 15 or the movable rod 14, and the guide rod 1 is inserted into the receiving rod 2. The upper base 15 has a through hole 17, which is a threaded hole. The movable rod 14 is threaded into the through hole 17 to achieve relative fixation between the movable rod 14 and the upper base 15.

[0032] The upper base 15 has a protrusion at the top forming a second insertion part 18, which is inserted into the second insertion hole 22. The lower base 13 has a movable cavity 19 and a through hole 20, which are connected. The cross-section of the movable cavity 19 is larger than the diameter of the through hole 20. The moving rod 14 passes through the through hole 20 and extends into the movable cavity 19. A limiting part 21 is formed on the portion of the moving rod 14 located in the movable cavity 19. The cross-sectional size of the limiting part 21 is the same as the cross-sectional size of the movable cavity 19.

[0033] The implementation principle of the automatic spring coil unloading and stacking auxiliary device in this application embodiment is as follows: When the auxiliary device is in use, the lower base 13 is also welded to the spring machine 12. The receiving rod 2 is replaceable, meaning there can be multiple receiving rods 2. When one receiving rod 2 is full, it can be removed and replaced with an empty one. Specifically, the replacement method is as follows: the upper base 15 is pressed down, further compressing the compression spring 16, causing the first insertion part 9 of the receiving rod 2 to disengage from the first insertion hole 8 at the bottom of the guide rod 1. Then, the receiving rod 2 is pulled upwards, causing its bottom to disengage from the second insertion part 18. The receiving rod 2 filled with spring coils 3 is then placed in a tempering furnace for heat treatment.

[0034] Example 2: Based on Example 1, the lower base has a spherical part 23, and a base 24 is located below the lower base. The spherical part 23 is located inside the base 24 and can rotate relative to the base.

[0035] Example 3: Based on Example 1 or 2, a pneumatic clamping assembly is further included. This pneumatic clamping assembly includes a base plate 25, a cylinder 26 fixed to the base plate 25, a connecting block 27 fixed to the piston rod of the cylinder 26, and a transmission rod 28 hinged in the middle to the base plate 25. Specifically, the transmission rod 28 has a rotating shaft 30 in the middle, which is rotatably connected to the base plate 25. One end of the transmission rod 28 is hinged to the connecting block 27, and a clamping plate 29 is fixed to the other end. Two transmission rods 28 and clamping plates 29 are symmetrically arranged. The clamping or releasing of the two clamping plates 29 onto the material rod 2 is achieved by the extension and retraction of the piston rod of the cylinder 26.
