Description

TECHNICAL FIELD

[0001] The utility model relates to test auxiliary equipment field, especially in a kind of mechanics performance test auxiliary mechanism for the riveting performance of car door panel is measured. BACKGROUND

[0002] Ball head support as the key component of car door panel closure, its riveting performance is directly related to whether door panel closure is reliable. In the traditional production process, it is mainly judged whether qualified indirectly by artificial visual confirmation riveting appearance;However, this artificial observation method cannot guarantee the quality after riveting, because there are many deficiencies in the inspection method of visual observation. First, visual observation is difficult to accurately confirm riveting quality, and there can be subtle differences in the operation of different inspectors, leading to inconsistent judgment. This inconsistency not only affects production efficiency, but also may cause defective products to flow into the market due to judgment errors, which has a negative impact on brand image and customer satisfaction, and has safety hazards. Therefore, we need to seek a more accurate and easy-to-operate measurement method to ensure the riveting quality of ball head support. SUMMARY

[0003] In view of the above problems, the purpose of the utility model is to provide a kind of mechanics performance test auxiliary mechanism that is accurate and uniform in measurement, and easy to operate.

[0004] To achieve the above object, the utility model provides a kind of mechanics performance test auxiliary mechanism, wherein, including the first auxiliary clamp and the second auxiliary clamp on the ball head support of the measured component.

[0005] Ball head support is composed of arch-shaped frame, spherical block provided on the top of arch-shaped frame, and welding site provided on both sides of arch-shaped frame.

[0006] The first auxiliary clamp includes left clamp block and right clamp block provided on the spherical block on the top of arch, for measuring left and right force, and bolt for fixedly connecting left clamp block and right clamp block.

[0007] The second auxiliary clamp includes connecting block connected with the welding site on both sides of arch-shaped frame, recess provided on connecting block, and connecting rod provided on recess and fixedly connected with connecting block for measuring up and down force.

[0008] The utility model discloses a beneficial effect is with the effect that measurement is accurate and unified, and simple operation. Because using, through the confirmation of part drawing, utilize first auxiliary fixture and second auxiliary fixture, simulate the direction of force when using, improve the reliability of test. Use high strength steel material to make, guarantee that pressurization force can be transmitted to test site, and can guarantee the service life of fixture, can be repeatedly used, need not re -make, energy -conserving and emission -reducing. The promotion of measurement reliability can guarantee the quality of riveting. Originally visual inspection, only can carry out appearance confirmation, now can draw riveting quality mechanics. Application, detection means is converted from visual appearance confirmation (there is misjudgment) to mechanics auxiliary mechanism test (test verification, does not exist misjudgment), and the degree of quality assurance is high. Increase the mechanical property auxiliary mechanism on the original mechanics detection equipment, expand the use range of measuring equipment. Need not invest special equipment (about 30000 yuan), and the cost of mechanical property auxiliary mechanism is about 1000 yuan, and the cost is greatly reduced. Thus can realize measurement accurate and unified, and simple operation effect. BRIEF DESCRIPTION OF DRAWINGS

[0010] The utility model will be further explained in detail in connection with the drawings.

[0011] As Figure 1 The utility model discloses a mechanical property test auxiliary mechanism, including first auxiliary fixture 2 and second auxiliary fixture 3 on the ball head support 1 of the measured component. Ball head support 1 is by arcuate frame 11, the spherical block 12 that is equipped with on arcuate frame 11 top, and the welding site 13 that is equipped with respectively on arcuate frame 11 both sides. First auxiliary fixture 2 includes the left clamping block 21 and right clamping block 22 that are equipped with measuring left and right force on the spherical block 12 on arcuate top, and the bolt that fixes and connects left clamping block 21 and right clamping block 22. Second auxiliary fixture 3 includes the connecting block 31 that is connected with the welding site 13 on arcuate frame 11 both sides simultaneously, the recess 32 that is equipped with on connecting block 31, and the connecting rod 33 that is equipped with with connecting block 31 fixed connection measuring up and down force on recess 32.

[0012] The mechanical property test auxiliary mechanism provides an efficient, accurate and easy-to-operate measurement method to ensure the accuracy and efficiency of the ball head riveting mechanical property, thereby ensuring the reliability and safety of the door lock mechanism. In view of the problems existing in the existing visual confirmation of riveting performance, the present application proposes an innovative measurement method. Compared with visual inspection, the measurement method of the present application can more accurately determine the riveting mechanical property and reduce the judgment errors caused by the experience difference of people. This not only can improve the production efficiency, but also can effectively prevent the defective products from flowing out due to judgment errors, thereby maintaining the brand image and customer satisfaction. At the same time, by adding an auxiliary mechanism to the existing universal testing machine, the auxiliary mechanism tool of the present application does not need a specific measurement program, and is easy to operate and learn, and can realize universal inspection and confirmation. In addition, the measurement method of the present application also has the characteristics of rapidness and high efficiency, greatly shortening the measurement time and improving the work efficiency. At the same time, since high-cost measurement equipment is not required, the implementation of the present application also reduces the operating cost of the enterprise. Therefore, the key point and the point to be protected of the present application lies in providing an accurate and efficient measurement method, which not only solves the inconsistency and error problem of the visual confirmation method, but also avoids the problems of high cost, long time consumption and high operation risk of the measurement method which can only be tested on a real vehicle. Through this innovation, the present application significantly improves the riveting quality of the ball head riveting bracket, and provides a powerful guarantee for the performance and safety of the door lock closing mechanism.
