Abstract
Description
Technical Field
[0001] This application relates to the field of test fixture technology, and in particular to a torque testing fixture and torque testing equipment. Background Technology
[0002] Torque testers are commonly used instruments in failure analysis and testing projects. They are frequently used to test whether the torsional resistance of a test component meets the required torque. A torque tester typically includes a fixed platform and a rotating shaft. Some test components are metal riveted products, which usually consist of a first and a second component riveted together. The torque between the first and second components needs to be tested using a torque tester to monitor the stability of the riveted product's strength. During the test, the first component is fixed to the fixed platform of the torque tester, and then the rotating shaft of the torque tester clamps the second component and rotates it.
[0003] However, most metal riveting products are incompatible with general torque machines due to their small size, flat shape, and complex structure. The fixed table of a general torque machine is difficult to hold the first part of the riveting product, and the rotating shaft of a general torque machine is also difficult to hold the second part of the riveting product. This makes it difficult, less accurate and efficient to test riveting products with a general torque machine. Utility Model Content

[0034] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.
[0035] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0036] Torque testers are commonly used instruments in failure analysis and testing projects. They are typically used to test whether the torsional resistance of a test piece meets the required torque. A torque tester usually includes a stationary table and a rotating shaft. For some test pieces that are metal-riveted products, please refer to [the relevant documentation / reference]. Figure 1 The riveted product typically consists of a first component 201 and a second component 202 riveted together. A torque tester is needed to measure the torque value between the first component 201 and the second component 202 to monitor the stability of the riveted product's strength. During the test, the first component 201 is fixed to the fixed platform of the torque tester, and then the rotating shaft of the torque tester clamps the second component 202 for rotation.
[0037] However, most metal riveting products are not compatible with general torque machines due to their small size, flat shape, and complex structure. The fixed table of a general torque machine is difficult to hold the first part 201 of the riveting product, and the rotating shaft of a general torque machine is also difficult to hold the second part 202 of the riveting product. This makes it difficult, and the accuracy and efficiency of testing riveting products with a general torque machine are relatively low.
[0038] The torque testing fixture of this application can help riveted products adapt to general torque machines, and can improve the convenience, accuracy and efficiency of testing riveted products with general torque machines.
[0039] To facilitate the reader's understanding of the inventive concept of this utility model, the specific structure of the torque testing fixture is described below:
[0040] Please see Figure 2-4The torque testing fixture 100 includes a base 1, a pressure block 2, and a torsion bar 3. The base 1 is used to place the workpiece 200 to be tested. The pressure block 2 is fixed to the base 1 to press the first component 201 of the workpiece 200 to the base 1. The pressure block 2 is provided with a first opening 22 to expose the second component 202 of the workpiece 200. One end of the torsion bar 3 is used to fix to the rotating shaft of the torque machine. When the torque testing fixture 100 is in operation, the base 1 can be easily fixed to the fixed platform of the torque machine, the pressure block 2 presses down on the first component 201, the rotating shaft of the torque machine can easily clamp one end of the torsion bar 3, and the other end of the torsion bar 3 extends into the first opening 22 and is fitted onto the second component 202. Driven by the rotating shaft, the torsion bar 3 drives the second component 202 to rotate relative to the first component 201 to test the torque value between the first component 201 and the second component 202. The torque testing fixture 100 of this application can assist riveted products in adapting to general torque machines, and can improve the convenience, accuracy and efficiency of testing riveted products with general torque machines.
[0041] In some embodiments, the base 1 is block-shaped and the pressure block 2 is block-shaped, which is beneficial for the fixed platform of the torque machine to clamp and fix the base 1 and the pressure block 2.
[0042] In some embodiments, please refer to Figure 5-9 The base 1 has a first surface 11 for placing the part to be tested 200. The pressure block 2 has a second surface 21 corresponding to the first surface 11. The second surface 21 is used to press the first part 201 onto the first surface 11, which helps to improve the stability of the first part 201. The first opening 22 penetrates the second surface 21.
[0043] In some embodiments, please refer to the following: Figure 10 The first surface 11 and the second surface 21 are curved surfaces, which can reduce the possibility of sliding between the pressure block 2 and the base 1.
[0044] In some embodiments, at least a portion of the first surface 11 is wavy and at least a portion of the second surface 21 is wavy, which can further reduce the possibility of slippage between the pressure block 2 and the base 1.
[0045] In some embodiments, please refer to Figure 4-8 The base 1 is provided with a second opening 12, which provides a buffer space for the torsion bar 3. When the other end of the torsion bar 3 extends into the first opening 22, when viewed from one end of the torsion bar 3 to the other end (first direction X), the other end of the torsion bar 3 overlaps with at least part of the second opening 12. If the movement amplitude of the other end of the torsion bar 3 along the first direction X increases, the other end of the torsion bar 3 can extend into the second opening 12, thereby reducing the possibility of the other end of the torsion bar 3 colliding with the base 1 and causing mutual damage.
[0046] In some embodiments, please refer to Figure 4 , Figure 5 , Figure 8 and Figure 9 The base 1 is provided with a first fixing hole 13 and a second fixing hole 14. The torque testing fixture 100 also includes a first fixing pin 41 and a second fixing pin 42. One end of the first fixing pin 41 is fixed to the first fixing hole 13, and the other end of the first fixing pin 41 is used to pass through one end of the first component 201. One end of the second fixing pin 42 is fixed to the second fixing hole 14, and the other end of the second fixing pin 42 is used to pass through the other end of the first component 201, so as to reduce the possibility of the first component 201 rotating relative to the base 1, and improve the testing accuracy of the torque value between the first component 201 and the second component 202.
[0047] In some embodiments, the second fixing hole 14 is close to the second opening 12 and the first fixing hole 13 is far from the second opening 12, which can further reduce the possibility of the first component 201 rotating relative to the base 1.
[0048] In some embodiments, the first fixing pin 41 is interference-fitted with the first fixing hole 13, and the second fixing pin 42 is interference-fitted with the second fixing hole 14.
[0049] In some embodiments, please refer to the following: Figure 11 The pressure block 2 is provided with a first limiting hole 23 and a second limiting hole 24. The first limiting hole 23 corresponds to the first fixing hole 13, and the second limiting hole 24 corresponds to the second fixing hole 14. The other end of the first fixing pin 41 extends into the first limiting hole 23, which can improve the stability of the first fixing pin 41. The other end of the second fixing pin 42 extends into the second limiting hole 24, which can improve the stability of the second fixing pin 42. In this way, the possibility of the first component 201 rotating relative to the base 1 can be further reduced.
[0050] In some embodiments, the first limiting hole 23 is located at one end of the first opening 22 and the second limiting hole 24 is located at the other end of the first opening 22, which can further reduce the possibility of the first component 201 rotating relative to the base 1.
[0051] In some embodiments, when viewed along the first direction X, the area of the first limiting hole 23 is larger than the area of the first fixing hole 13, which is conducive to the other end of the first fixing pin 41 extending into the first limiting hole 23, and the area of the second limiting hole 24 is larger than the area of the second fixing hole 14, which is conducive to the other end of the second fixing pin 42 extending into the second limiting hole 24.
[0052] In some embodiments, please refer to Figure 4 , Figure 5 , Figure 8 and Figure 12The base 1 has a third fixing hole 15 at one end and a fourth fixing hole 16 at the other end. The pressure block 2 has a fifth fixing hole 25 at one end and a sixth fixing hole 26 at the other end. The torque testing fixture 100 also includes a third fixing pin 43 and a fourth fixing pin 44. One end of the third fixing pin 43 is fixed to the third fixing hole 15 and the other end of the third fixing pin 43 is fixed to the fifth fixing hole 25. One end of the fourth fixing pin 44 is fixed to the fourth fixing hole 16 and the other end of the fourth fixing pin 44 is fixed to the sixth fixing hole 26, so that the pressure block 2 is fixed to the base 1.
[0053] In some embodiments, the third fixing pin 43 and the third fixing hole 15 are interference-fitted, the third fixing pin 43 and the fifth fixing hole 25 are interference-fitted, the fourth fixing pin 44 and the fourth fixing hole 16 are interference-fitted, and the fourth fixing pin 44 and the sixth fixing hole 26 are interference-fitted.
[0054] In some embodiments, please refer to Figure 4 and Figure 8 One end of the base 1 is provided with a first threaded hole (not shown in the figure), and the other end of the base 1 is provided with a second threaded hole (not shown in the figure). One end of the pressure block 2 is provided with a first hole 27, and the other end of the pressure block 2 is provided with a second hole 28. The torque testing fixture 100 also includes a first screw connector (not shown in the figure) and a second screw connector (not shown in the figure). One end of the first screw connector abuts against the pressure block 2, and the other end of the first screw connector passes through the first hole 27 and is screwed into the first threaded hole. One end of the second screw connector abuts against the pressure block 2, and the other end of the second screw connector passes through the second hole 28 and is screwed into the second threaded hole, so that the pressure block 2 is fixed to the base 1, and the possibility of relative movement between the pressure block 2 and the base 1 in the first direction X can be reduced. Furthermore, the first threaded hole and the third fixing hole 15 are respectively located on both sides of one end of the base 1, the second threaded hole and the fourth fixing hole 16 are respectively located on both sides of the other end of the base 1, the first hole 27 and the fifth fixing hole 25 are respectively located on both sides of one end of the pressure block 2, and the second hole 28 and the sixth fixing hole 26 are respectively located on both sides of the other end of the pressure block 2, so as to further improve the stability between the pressure block 2 and the base 1. Furthermore, since the screw connection stability is better in the areas of the first hole 27 and the second hole 28, by setting the first hole 27 close to the first limiting hole 23 and the second hole 28 close to the second limiting hole 24, the stability of the first fixing pin 41 and the second fixing pin 42 can be further improved.
[0055] In some embodiments, one end of the pressure block is provided with a first threaded hole, and the other end of the pressure block is provided with a second threaded hole. One end of the base is provided with a first hole, and the other end of the base is provided with a second hole. The torque testing fixture also includes a first screw connector and a second screw connector. One end of the first screw connector abuts against the base, and the other end of the first screw connector passes through the first hole and is screwed into the first threaded hole. One end of the second screw connector abuts against the base, and the other end of the second screw connector passes through the second hole and is screwed into the second threaded hole, so that the pressure block is fixed to the base.
[0056] In some embodiments, please refer to Figure 4 , Figure 7 and Figure 13 The other end of the torsion bar 3 is provided with a groove 31, which is used to fit onto the second component 202 so that the torsion bar 3 can drive the second component 202 to rotate through the groove 31.
[0057] In some embodiments, please refer to the following: Figure 14 One end of the torsion bar 3 is provided with a notch 32, which facilitates the rotation shaft of the torque machine to clamp one end of the torsion bar 3. The notch 32 is provided with a plane 321, which can be clamped by the rotation shaft of the torque machine to improve the stability of the connection between the rotation shaft and the torsion bar 3.
