[0021] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific manner, and therefore should not be construed as a limitation to the present utility model. Terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0022] As Figure 1 and Figure 2 shown, a feeding tooling includes an outer mold sleeve 8 and an inner mold sleeve 7 which are slidably connected. The inner mold sleeve 7 is arranged inside the outer mold sleeve 8, and the inner mold sleeve 7 and the outer mold sleeve 8 are slidably connected through clearance fit.

[0023] An inner mold core 6 is arranged inside the inner mold sleeve 7, and the inner mold sleeve 7 and the inner mold core 6 are slidably and elastically connected. The inner mold core 6 includes a base 61 and a pushing portion 62 connected to the base 61. The base 61 is in clearance fit with the inner mold sleeve 7, thereby realizing the sliding connection between the inner mold sleeve 7 and the inner mold core 6. At the same time, a fixed mold core 4 and an inner spring 5 are arranged inside the inner mold sleeve 7. The fixed mold core 4 is fixedly arranged at one end of the opening of the inner mold sleeve 7. One end of the inner spring 5 is connected to the fixed mold core 4, and the other end is connected to the inner mold core 6. In this embodiment, one end of the inner spring 5 is sleeved on the outer periphery of the pushing portion 62 and abuts against the front end of the base 61. At the same time, in this embodiment, the outer diameter of the fixed mold core 4 at one end towards the base 61 is smaller than the outer diameter at one end of the opening of the inner mold sleeve 7, so that the other end of the inner spring 5 can be sleeved on the outer periphery of the fixed mold core 4 at the opening end of the inner mold sleeve 7, thereby realizing the abutment of both ends of the inner spring 5. Of course, in other embodiments, the inner spring 5 can also be directly connected to the fixed mold core 4 and the base 61 (such as by welding). Due to the arrangement of the inner spring 5 and the fixed mold core 4, the elastic connection between the inner mold sleeve 7 and the inner mold core 6 is realized.

[0024] In this embodiment, the fixed mold core 4 is hollow, and the inner diameter of the fixed mold core 4 is larger than the outer diameter of the pushing portion 62. Thus, when the inner mold core 6 is pushed forward by force, the front end of the pushing portion 62 can pass through the hollow portion of the fixed mold core 4 and be pushed forward.

[0025] The inner mold core 6 is connected to the movable end of a first linear motion mechanism 11. The movable end of the first linear motion mechanism 11 passes through the bottoms of the outer mold sleeve 8 and the inner mold sleeve 7 and is connected to the inner mold core 6. The first linear motion mechanism can be a mechanism that provides linear motion such as an electric cylinder or a cylinder. By pushing the inner mold core 6 through the movable end of the first linear motion mechanism 11, the inner mold core 6 can thus push related parts such as a nut 31, etc. towards the opening end of the inner mold sleeve 7, and then be installed on the workpiece 32 to be assembled.

[0026] The outer sleeve of the movable end of the first linear motion mechanism 11 is provided with a push rod spring 9, one end of the push rod spring 9 is provided at the bottom of the outer mold sleeve 8, and the other end is provided at the front end of the push rod fixing ring 10. The setting of the push rod spring 9 can effectively buffer the vibration when the movable end of the first linear motion mechanism 11 is retracted, can reduce mechanical damage, extend the use time, and will not be displaced due to long-term use, so as to maintain the movement accuracy.

[0027] like Figure 3 As shown, when feeding, the first linear motion mechanism 11 is started, and its moving end pushes the inner mold core 6 to move in the direction of the workpiece 32 to be assembled. The inner mold core 6 is connected to the inner mold sleeve 7 through the inner spring 5 and the fixed mold core 4. The inner mold sleeve 7 moves forward, and the inner mold core 6 is continuously subjected to force, and finally the related parts such as the nut 31 move in the direction of the opening of the inner mold sleeve 7 until it contacts the workpiece 32 to be assembled. The inner mold core 6 continues to move forward and pushes the related parts such as the nut 31 into the specific installation position of the workpiece 32 to be assembled, and the active end of the first linear motion mechanism 11 returns. However, when the workpiece 32 to be assembled is small, smaller than the standard part, so that the workpiece 32 to be assembled is far away from the outer mold sleeve 8, and the gap between the two is too large, after the movement stroke of the inner mold sleeve 7 reaches the limit, the inner mold core 6 in this patent continues to be pushed by the first linear motion mechanism 11, and the thrust of the inner mold core 6 overcomes the spring resistance, as shown in FIG. Figure 4 and Figure 5 As shown, the machine continues to move forward and finally feeds the related parts such as the nut 31 into the workpiece 32 to be assembled, thereby completing the assembly. This solves the problem that the gap between the workpiece 32 to be assembled and the position of the feeding tooling is too large or the smaller products are smaller than the standard size and are easily dropped during the feeding process, thereby causing the product to not be fed into place.

[0028] At the same time, through the setting of the inner spring 5, when the inner mold core 6 is forced to retreat toward the base 61, the inner spring 5 can buffer part of the force on the inner mold core 6, reduce the vibration and collision of the inner mold core 6, and thus prevent damage or loss of precision caused by collision.

[0029] In this embodiment, Figure 1 , 3 As shown in Figures 4 and 5, the outer mold sleeve 8 is arranged at the movable end of the second linear motion mechanism 23. The second linear motion mechanism 23 is fixed on the linear motion mechanism fixed mold 19, and the linear motion mechanism fixed mold 19 is installed on the vertical fixed plate 14. The vertical fixed plate 14 is also provided with a linear bearing 15, and the linear bearing 15 cooperates with the linear slide 20. The end of the linear slide 20 is connected to the outer mold sleeve fixed mold 16, and the outer mold sleeve fixed mold 16 is connected to the movable end of the second linear motion mechanism 23 and the bottom is connected to the outer mold sleeve 8. In this embodiment, the second linear motion mechanism is a cylinder. Of course, in other embodiments, it can also be an electric cylinder, a synchronous belt, etc. to provide a mechanism for linear motion. Through the setting of the second linear motion mechanism 23, the outer mold sleeve 8 can be driven to move up and down, thereby completing the process of picking up and feeding materials.

[0030] A material receiving die 2 is arranged on the opposite sides of the outer mold sleeve 8, and a feeding chute 1 is arranged above the material receiving die 2. A vertical fixing plate 14 is arranged between the material receiving die 2 and the outer mold sleeve 8. A feeding channel 141 is arranged at the lower end of the vertical fixing plate 14. The feeding channel 141 is communicated with the outlet of the material receiving die 2, and the two are integrally connected. A material receiving die push rod 3 is slidably connected to one end of the material receiving die 2 away from the outer mold sleeve 8. In this embodiment, the vertical fixing plate 14 is installed on the lower die 12 of the fixed headstock, and the lower die 12 of the fixed headstock is installed on a numerical control headstock (not shown).

[0031] When the present utility model is in use, when the material on the feeding chute 1 slides into the material receiving die 2, the material receiving die push rod 3 pushes the material such as a nut 31 into the feeding channel 141, and then into the inner mold sleeve 7. After the material enters the inner mold sleeve 7, the second linear motion mechanism 23 moves, and the moving end of the second linear motion mechanism 23 moves downward, moving the outer mold sleeve 8 and the inner mold sleeve 7 as a whole downward until they are aligned with the workpiece 32 to be assembled. At this time, the first linear motion mechanism is started to feed the material into the workpiece 32 to be assembled.

It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present utility model through logical analysis, reasoning or limited experiments based on the concept of the present utility model on the basis of the existing technology shall fall within the protection scope determined by the claims.
