[0002] Torsion springs are rotation springs that include a spring body and two ends disposed at both ends of the spring body. The two ends of the torsion spring are fixed to other components.

Since the connecting portion 110, the first end 120 and the second end 130 of the double torsion spring are bent lines, under the action of material stress, there is a risk that these three will be deformed and the shape will not meet the design requirements, thereby affecting the performance of the double torsion spring.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.
[0029] Combination Figures 1 to 3 As shown, the double torsion spring detection fixture of this embodiment mainly includes: a bracket 1, a base plate 2 and a detection component. Among them, the base plate 2 is fixedly arranged on the bracket 1 at an angle relative to the horizontal plane, and the detection component is installed on the base plate 2. The detection component includes a first detection block 31, and the first detection block 31 has a first inner cavity 311. The first inner cavity 311 is used to detect the connecting portion 110, the first end 120 and the second end 130 of the double torsion spring along a direction perpendicular to the base plate 2 (defined as the Z direction of this fixture).
[0030] Specifically, some grooves are opened on the first detection block 31, and then the openings of the grooves are directed toward the bottom plate 2 and the first detection block 31 is fixed on the bottom plate 2. The grooves and the bottom plate 2 surround a first inner cavity 311. When the double torsion spring needs to be tested, the double torsion spring is placed on the bottom plate 2, and the double torsion spring is pushed in from the feeding end of the first detection block 31. If the deformation of the connecting portion 110, the first end portion 120 and the second end portion 130 along the Z direction is less than the preset value (that is, the dimensions of the three meet the design values), the double torsion spring can pass through the first inner cavity 311 smoothly, and the double torsion spring can be determined to be a good product. Otherwise, the double torsion spring cannot pass through the first inner cavity 311 smoothly and is determined to be a defective product.
[0031] Specifically, combined Figure 2 and Figure 4 As shown, the detection assembly of this embodiment may further include a second detection block 32, which is disposed on one side of the feeding end of the first detection block 31. A first detection slot 321 is formed between the second detection block 32 and the first detection block 31, and the first detection slot 321 is used to detect the first end of the double torsion spring along the X and Y directions.
[0032] Furthermore, the detection assembly of this embodiment may also include a third detection block 33, which is disposed on the other side of the feeding end of the first detection block 31. A second detection slot 331 is formed between the third detection block 33 and the first detection block 31, and a third detection slot 332 is formed between the third detection block 33 and the second detection block 32. The second detection slot 331 is used to detect the second end 130 of the double torsion spring along the X and Y directions, and the third detection slot 332 is used to detect the connecting portion 110 of the double torsion spring along the X direction.
[0033] like Figure 5 As shown, the detection fixture of this embodiment may also include a material stripping assembly. Accordingly, a long strip-shaped through hole 21 is provided in the area corresponding to the third detection slot 332 of the base plate 2. The through hole 21 is used for at least part of the material stripping assembly to pass through to act on the connecting portion 110 of the double torsion spring, so that the material stripping assembly can strip the double torsion spring along the discharge end away from the first detection block 31. Specifically, the material stripping assembly includes a slide rail 41, a fixed block 42 and a material stripping nail. The slider is fixedly connected to the side of the base plate 2 away from the first detection block 31, the fixed block 42 can be slidably connected to the slide rail 41, and the material stripping nail is penetrated on the fixed block 42. Further, the material stripping nail includes a material stripping rod 431 and a handle 432. The material stripping rod 431 is penetrated on the fixed block 42 and is threadedly connected to the fixed block 42. One end of the material stripping rod 431 is used to penetrate into the through hole 21 of the base plate 2, and the other end is connected to the handle 432. With the above solution, when the double torsion spring cannot pass through the detection component smoothly during the detection process and is determined to be a defective product, the defective product can be pushed out from the feeding end of the first detection block 31 by the material return component to facilitate material return.
[0034] like Figure 2 As shown, the detection device of this embodiment also includes a material discharge chute 5, which is connected to one end of the bottom plate 2 corresponding to the discharge end of the first detection block 31. When the double torsion spring successfully passes the detection of the detection component, it will slide out from the discharge end of the first detection block 31, and then slide down along the material discharge chute 5 into the material box.
[0035] The method of using the double torsion spring detection fixture of this embodiment is as follows: before use, first rotate the stripping pin until the end of the stripping rod 431 is lower than the upper surface of the through hole 21, so as to prevent the stripping rod 431 from affecting the normal sliding of the double torsion spring; during detection, first place the double torsion spring on the bottom plate 2, and the first end 120, the second end 130 and the connecting portion 110 correspond to the first detection groove 321, the second detection groove 331 and the third detection groove 332 respectively. If the double torsion spring cannot be placed in one of the above three detection grooves, the double torsion spring is judged to be defective and can be directly Then take out the defective products from the tool; if the double torsion spring can be placed in the three inspection grooves mentioned above, but the material is stuck during the downward sliding process (first inner cavity 311), the double torsion spring is judged to be a defective product. At this time, the material return pin can be rotated until the end of the material return rod 431 is higher than the upper surface of the through hole 21 so that it can be against the double torsion spring connecting part 110, and the material return pin is slid upward to push the connecting part 110 of the double torsion spring to realize the return of the defective product; if the double torsion spring can be released smoothly from the beginning and slide down smoothly along the discharge direction, it is judged to be a good product.
[0036] In summary, the double torsion spring detection fixture of this embodiment cooperates with the detection component and the base plate 2 to perform limit detection on the connecting part 110, the first end 120 and the second end 130 of the double torsion spring along the X / Y / Z direction, which can assist personnel to quickly determine whether the double torsion spring is a good product; the fixture has a simple structure and is easy to operate.

The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
