Description

Technical Field

[0001] The utility model relates to the field of spring processing, in particular to a special-shaped spring for automobiles. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external forces and return to their original shape after the external force is removed. It is also called "spring". It is generally made of spring steel. There are many types of springs. According to their shapes, they mainly include spiral springs, scroll springs, leaf springs, special-shaped springs, etc. The difference between special-shaped springs and conventional springs is that the spring itself is irregular, with bends and a large number of complex angle designs, and is suitable for some occasions with special uses. Among the many types of special-shaped springs currently available on the market, only a small number of special-shaped springs are used for automobile lathes and wipers, and due to the characteristics of special-shaped springs, special jigs are often required to test their performance. Utility Model Content

[0003] The utility model aims to provide a special-shaped spring for automobiles to solve the problems existing in the above-mentioned prior art.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A special-shaped spring for automobiles, comprising a spring body and a detection fixture, wherein the spring body comprises a pressing portion, an energy storage portion and a supporting portion;

[0006] The pressing portion includes a first cylindrical structural primitive, two first angle structural primitives and a second cylindrical structural primitive, the left and right ends of the first cylindrical structural primitive are both provided with first angle structural primitives, the other ends of the first angle structural primitives are both arranged downward, and the downward ends of the first angle structural primitives are both aligned with one end of the second cylindrical structural primitive;

[0007] The energy storage part is arranged in pairs at the two ends of the mortgage part, and the energy storage part includes two second angle structural primitives, a third cylindrical structural primitive and a third angle structural primitive, one end of the second angle structural primitive is connected to the other end of the second cylindrical structural primitive, the other end of the second angle structural primitive faces the direction away from the first cylindrical structural primitive, the third cylindrical structural primitive is arranged in parallel with the first cylindrical structural primitive, one end of the third cylindrical structural primitive is connected to the other end of the second angle structural primitive, the other end of the third cylindrical structural primitive is connected to one end of the third angle structural primitive, and the angle of the third angle structural primitive is arranged at an obtuse angle;

[0008] The other end of the energy storage part is connected to a support part, and the support part includes two fourth cylindrical structural primitives, a fourth angle structural primitive, a fifth cylindrical structural primitive, a fifth angle structural primitive and a sixth cylindrical structural primitive, one end of the fourth cylindrical structural primitive is connected to the other end of the third angle structural primitive, the other end of the fourth cylindrical structural primitive is connected to one end of the fourth angle structural primitive, the other end of the fourth angle structural primitive is connected to one end of the fifth cylindrical structural primitive, the fifth cylindrical structural primitive is orthogonal to the first cylindrical structural primitive, the other end of the fifth cylindrical structural primitive is connected to one end of the fifth angle structural primitive, the other end of the fifth angle structural primitive is connected to one end of the sixth cylindrical structural primitive, and the fifth cylindrical structural primitive is orthogonal to the sixth cylindrical structural primitive;

[0009] The detection fixture is provided with a receiving groove, and a spring body is arranged in the receiving groove.

[0010] By adopting the above technical scheme, the special-shaped spring made of spring steel wire has quite complicated bending parts and can also be used for its corresponding purposes. The pressure part can resist the force-applying object, while the energy storage part converts the received force into deformation energy and stores it. At the same time, the energy storage part also plays the role of connecting the pressure part and the supporting part, and the supporting part is responsible for fixing on the force-applying object.

[0011] In a further embodiment, the width of the accommodating groove is slightly larger than the spring body.

[0012] By adopting the above technical solution, the function of the detection fixture and the accommodating groove itself is to detect whether the shape of the spring body meets the requirements. Therefore, it is not necessary to make it fit perfectly. A slightly wider shape is more convenient for testing the spring body, which effectively improves efficiency.

[0013] In a further embodiment, a plurality of taking-and-releasing grooves are provided on the accommodating groove, and the taking-and-releasing grooves are used to conveniently take out the spring body.

[0014] By adopting the above technical solution, the length of both ends of the spring body is slightly shorter than the accommodating groove. Therefore, if the pick-up and release groove is not provided, it will be difficult to remove the spring after the test is completed. The fixture itself also has a certain weight, and it is rather troublesome to turn it over and pour it out. Therefore, it is more convenient to provide a pick-up and release groove.

[0015] In a further embodiment, the access grooves are symmetrically arranged at the energy storage parts at both ends of the spring body.

[0016] By adopting the above technical solution, the special-shaped spring itself is relatively thin. Although it has a certain strength, it is still possible to have a certain impact on its shape by pulling it from only one side. Therefore, it is necessary to symmetrically set the taking and placing grooves on both sides to facilitate taking out with both hands at the same time.

[0017] In a further embodiment, four inner sides of the pick-and-place groove are all provided with rounded corners.

[0018] By adopting the above technical solution, the rounded corners in the pick-and-place groove can protect the special-shaped spring from accidental friction and scratches during the process.

[0019] In a further embodiment, the side edges of the detection fixture are all provided with rounded corners.

[0020] By adopting the above technical solution, it is possible to avoid unnecessary damage caused by collision between the side edge of the inspection fixture and other workpieces.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. Through the arrangement of the pressing part, the connecting part and the supporting part, the pressing part of the spring body can be pressed against the wiper strip of the wiper, and the supporting part of the spring body can be pressed against the wiper arm of the wiper, so that the wiper can store deformation energy through the connecting part during the process of completing one action, thereby ensuring that the wiper can be smoothly reset after the action is completed;

[0023] 2. By setting the rounded corners on the side lines of the detection fixture, it is possible to protect the fixture itself and other workpieces in the processing environment while detecting the spring tip;

[0024] 3. By setting the taking and placing grooves, force can be applied to the energy storage parts on both sides of the spring body at the same time, avoiding deformation of the spring body due to force problems, and achieving the effect of safely removing the spring body from the fixture.
