Abstract
Description
Technical Field
[0001] The utility model relates to the field of PIN wire product limiting, in particular to a guide groove shrinking tooling. Background Technique
[0002] The guide groove shrinking tooling is a supporting device for PIN wire product limiting, and is used for the stator production equipment of flat wire motors. Before the fork PIN wire is inserted into the stator, the tooling fingers extend to form a guide groove between the two fingers to receive and guide the fork PIN wire. With the continuous development of technology, the manufacturing process requirements for the guide groove shrinking tooling are also getting higher and higher.
[0003] The existing guide groove shrinking tooling has certain drawbacks when in use. First of all, the existing tooling cannot limit the PIN wire product well, and the PIN product is prone to damage during the insertion process, which is not conducive to people's use. In addition, the notch is relatively single and cannot adapt to more types of PIN wire products, which brings certain adverse effects to the actual use process. Therefore, we propose a guide groove shrinking tooling. Summary of the Utility Model
[0004] Technical problems to be solved: Aiming at the deficiencies of the prior art, the utility model provides a guide groove shrinking tooling. Before the fork PIN wire is inserted into the stator, the tooling fingers extend to form a guide groove between the two fingers to receive and guide the fork PIN wire. After the PIN wire is inserted into the product and no longer needs to be guided, it can automatically close and retract, ensuring that the PIN passes through this mechanism safely. The PIN feet can be tightened into the notch size to ensure that the product is not damaged during the insertion process. In addition, the size of the guide groove of this tooling can be freely controlled, which is more flexible and can adapt to different sizes of products, effectively solving the problems in the background technique.
[0005] Technical solution: To achieve the above purpose, the technical solution adopted by the utility model is: A guide groove shrinking tooling, including a finger shrinking mechanism. An elastic finger is arranged in the middle of the finger shrinking mechanism, and a PIN product is arranged inside the elastic finger. A positioning member and an adjusting member are installed outside the finger shrinking mechanism. A cylinder is installed on the positioning member, and an adjusting rod is movably arranged at the front end of the cylinder. An adjusting shaft is arranged between the adjusting rod and the adjusting member.
[0006] Preferably, each group of the elastic fingers includes two groups of finger supports, and a rotating shaft and a spring are arranged between the two groups of the finger supports. A guide base is positioned and installed at the rear end of the finger supports. A slot is provided on the inner side of the elastic fingers at the position where the PIN product is arranged. When the finger retraction mechanism extends the guide base, the elastic fingers are in an initial free state, and a closed slot is formed between the elastic fingers and the two finger supports. The slot can be used to allow the PIN to be introduced into the PIN product in the direction of the slot to ensure that the PIN product will not be inserted off-center. After the PIN product is inserted, the finger retraction mechanism is retracted. At this time, the specific bevel on the elastic finger contacts the PIN product. When the spring force is overcome, the finger retraction mechanism unlocks the slot into a C shape, thereby separating from the inserted PIN product.
[0007] Preferably, the PIN product is positioned by elastic fingers inside the finger retracting mechanism.
[0008] Preferably, the cylinder drives the adjusting rod to telescope, and the adjusting rod drives the finger retraction mechanism and the elastic finger adjustment movement through the adjusting shaft and the adjusting member.
[0009] Preferably, the two groups of finger supports are elastically contracted via a rotating shaft and a spring.
[0010] Preferably, the inside of the elastic finger engages the PIN product through a notch.
[0011] Beneficial effects: Compared with the prior art, the utility model provides a guide groove retraction tooling with the following beneficial effects: This guide groove retraction tooling, the guiding mechanism can be used for inserting the forked PIN wire into the stator before the tooling fingers are extended to form a guide groove between the two fingers for connecting the forked PIN wire. After the PIN wire is inserted into the product and no longer needs to be guided, it can be automatically closed and retracted to ensure the safety of the PIN passing through this mechanism. The PIN foot can be tightened to the slot size to ensure that the insertion process does not damage the product. In addition, the size of the guide groove of the tooling can be freely controlled, which is more flexible and can adapt to products of different sizes. The mechanism is mainly composed of a finger retraction mechanism, a guide base, elastic fingers, a spring, a cylinder, a rotating shaft, etc. When the finger retraction mechanism extends the guide base, such as Figure 5 The elastic finger is in the initial free state. It forms a closed slot with the two guide bases. This slot can be used to guide the PIN in the direction of the slot to ensure that the PIN is not inserted in an offset manner. When the PIN is inserted, the finger retraction mechanism is retracted. At this time, the specific angle on the elastic finger contacts the PIN. When the spring force is overcome, Figure 6, the finger contracts the unlocking notch into a C shape to separate from the inserted PIN, thus solving the problem that the conventional notch can only separate from the PIN when the PIN completely passes through the guiding groove. The entire guiding groove contraction tooling has a simple structure, is convenient to operate, and has a better effect than the traditional method. Description of the Drawings

[0022] As Figures 1-6 shown, a guide groove shrinking tooling includes a finger shrinking mechanism 1. An elastic finger 3 is arranged in the middle of the finger shrinking mechanism 1. A PIN product 2 is arranged inside the elastic finger 3. A positioning member 6 and an adjusting member 4 are installed outside the finger shrinking mechanism 1. A cylinder 7 is installed on the positioning member 6. An adjusting rod 8 is movably arranged at the front end of the cylinder 7. An adjusting shaft 5 is arranged between the adjusting rod 8 and the adjusting member 4. This guiding mechanism can be used before the fork PIN wire is inserted into the stator. The tooling fingers extend to form a guide groove between the two fingers first for guiding the fork PIN wire. After the PIN wire is inserted into the product and no longer needs the guide, it can automatically close and retract. It can safely ensure that the PIN passes through this mechanism, and the PIN feet can be tightened into the notch size to ensure that the product is not damaged during the insertion process. In addition, the size of the guide groove of this tooling can be freely controlled, which is relatively flexible and suitable for products of different sizes.
[0023] Further, each set of elastic fingers 3 includes two sets of finger bodies 13, and a rotating shaft 9 and a spring 10 are arranged between the two sets of finger bodies 13. A guiding base 11 is positioned and installed at the rear end of the finger body 13. A notch 12 is provided at the position where the PIN product 2 is arranged on the inner side of the elastic finger 3. When the finger contraction mechanism 1 extends the guiding base 11, the elastic finger 3 is in an initial free state, and a closed notch 12 is formed between it and the two finger bodies 13. The notch 12 can be used to guide the PIN into the PIN product 2 in the direction of the notch 12 to ensure that the PIN product 2 is not inserted obliquely. After the PIN product 2 is inserted, the finger contraction mechanism 1 retracts. At this time, the specific bevel angle on the elastic finger 3 contacts the PIN product 2. When overcoming the spring force, the finger contraction mechanism 1 unlocks the notch 12 into a C shape, so as to separate from the inserted PIN product 2.
[0024] Further, the PIN product 2 is positioned inside the finger contraction mechanism 1 through the elastic finger 3.
[0025] Further, the air cylinder 7 drives the adjusting rod 8 to expand and contract, and the adjusting rod 8 drives the finger contraction mechanism 1 and the elastic finger 3 to adjust through the adjusting shaft 5 and the adjusting part 4.
[0026] Further, the two sets of finger bodies 13 are elastically contracted through the rotating shaft 9 and the spring 10.
[0027] Further, the PIN product 2 is clamped inside the elastic finger 3 through the notch 12.
[0028] Working principle: The utility model includes a finger contraction mechanism 1, a PIN product 2, an elastic finger 3, an adjusting part 4, an adjusting shaft 5, a positioning part 6, an air cylinder 7, an adjusting rod 8, a rotating shaft 9, a spring 10, a guiding base 11, and a notch 12. This mechanism is mainly composed of a finger contraction mechanism, a guiding base, an elastic finger, a spring, an air cylinder, a rotating shaft, etc. When the finger contraction mechanism extends the guiding base, Figure 5 the elastic finger is in an initial free state, and a closed notch is formed between it and the 2 guiding bases. This notch can be used to guide the PIN into the PIN in the direction of this notch to ensure that the PIN is not inserted obliquely. When the PIN is inserted, the finger contraction mechanism retracts. At this time, the specific bevel angle on the elastic finger contacts the PIN. When overcoming the spring force, Figure 6, the finger contracts to unlock the notch into a C shape and thus separates from the inserted PIN, solving the problem that the conventional notch can only separate from the PIN when the PIN completely passes through the guiding groove. This guiding mechanism can be used before the fork PIN wire is inserted into the stator. The tooling fingers extend to form a guiding groove between the two fingers first to guide and introduce the fork PIN wire. After the PIN wire is inserted into the product and no longer requires guiding, it can automatically close and retract. The safety guarantee is that the PIN passes through this mechanism, which can tighten the PIN feet into the notch size to ensure that the product is not damaged during the insertion process. In addition, the size of the guiding groove of this tooling can be freely controlled, which is relatively flexible and suitable for products of different sizes.
