Description

Technical Field

[0001] This utility model relates to the field of automobile wheel hub processing and manufacturing technology, specifically to an auxiliary tooling for detecting the viscosity of wheel hub labels. Background Technology

[0002] Existing tensile testing machines are commonly used equipment for testing the mechanical properties of materials. Their core function focuses on routine mechanical tests of various materials, including metals and non-metals. For example, by applying axial tensile force, they can test key indicators such as tensile strength, yield strength, and elongation, playing a fundamental role in material quality verification and performance development. However, limited by their initial design, the application scenarios of this equipment are relatively limited, only meeting the mechanical property testing needs of the materials themselves. They cannot adapt to other types of specialized testing tasks, resulting in some degree of idle equipment functions and wasted resources.

[0003] Further analysis of the equipment's structural characteristics reveals that the tensile testing machine has a large downward space between the worktable and the upper crossbeam. This structural advantage provides a key physical basis for the equipment's functional expansion. There is no need for large-scale modifications to the main frame, power system, and other core components of the equipment; the testing scenarios can be extended simply by adding adaptive auxiliary devices. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary tooling for detecting the viscosity of wheel hub labels, thereby solving the above problems.

[0005] To achieve the above objectives, the following technical solutions are provided:

[0006] An auxiliary fixture for testing the viscosity of wheel hub labels, used in conjunction with a tensile testing machine, includes: a positioning fixture and a connecting fixture. The positioning fixture includes: a slot assembly, a rotating nut assembly, a limiting mechanism, a support screw, a pad, and a base plate. The pad is located above the base plate, and the base plate is hinged to one side of the pad. The limiting mechanism is fixedly connected to the top of the pad near the hinge end between the pad and the base plate. The support screw passes through the base plate away from the hinge end between the pad and the base plate and can slide relative to the base plate. Its top abuts against the pad. The rotating nut assembly is screwed onto the support screw and is located on the upper and lower sides of the base plate, respectively. The slot assembly is located at the bottom of the base plate and is located on both sides of the support screw.

[0007] Preferably, the connecting fixture includes: a steel sample block, a steel wire rope, and a fixing nut, wherein the steel sample block is fixedly connected to the steel wire rope by the fixing nut.

[0008] Preferably, the cross-section of the card slot assembly is an inverted "T" shape.

[0009] Preferably, the limiting mechanism includes a limiting block and a locking block, and there are two locking blocks, which are respectively disposed at both ends of the limiting block.

[0010] Preferably, the contour of the limiting block is exactly matched and abuts against the outer contour of the wheel hub, and the locking block has an "L" shaped structure to engage with the wheel hub.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention adds a customized pad to the worktable of the testing machine. By precisely controlling the thickness and flatness of the pad, the reference surface of the wheel workpiece is ensured to be level after placement. At the same time, it compensates for the difference between the downward space and the height of the workpiece, so that the logo label detection area can be accurately aligned with the force sensor of the tensile testing machine. On the other hand, a special connecting fixture is designed and installed. One end of the fixture is rigidly connected to the upper clamp of the testing machine, and the other end is stably attached to the wheel logo label through a modular interface. It can be quickly adjusted according to the size and shape of the wheel logo label of different specifications, ensuring that the tensile force can be applied evenly and vertically to the surface of the logo label during the testing process.

[0013] Through the above modifications, the tensile testing machine, which was originally only capable of material testing, has been successfully expanded to include a function for testing the viscosity of wheel logo labels. It can simulate the peeling force, adhesion force, and other working conditions experienced by logo labels in actual use scenarios, accurately collect and analyze the adhesion stability data of logo labels under different tensile forces, and provide a reliable testing method for the quality control of wheel exterior parts. This not only revitalizes existing equipment resources and reduces the procurement cost of dedicated testing equipment, but also further improves the whole-process testing system for wheel products.

Detailed Implementation

[0021] The following is a detailed description of this design scheme with reference to the accompanying drawings.

[0022] An auxiliary fixture for testing the viscosity of wheel hub labels, used in conjunction with a tensile testing machine 12, includes: a positioning fixture and a connecting fixture. The positioning fixture is used to place the car wheel hub 11 and includes: a slot assembly 1, a rotating nut assembly 2, a limiting mechanism, a support screw 7, a pad 8, and a base plate 9. The pad 8 is located above the base plate 9, and the base plate 9 is hinged to one side of the pad 8. The limiting mechanism is fixedly connected to the top of the pad 8 near the hinge end between the pad 8 and the base plate 9. The support screw 7 passes through the base plate 9 away from the hinge end between the pad 8 and the base plate 9 and can slide relative to the base plate 9. Its top abuts against the pad 8. The rotating nut assembly 2 is screwed onto the support screw 7 and is located on the upper and lower sides of the base plate 9, respectively. The slot assembly 1 is located at the bottom of the base plate 9 and is located on both sides of the support screw 7. The connecting fixture is connected to the top of the tensile testing machine 12 and includes: a steel sample block 4, a steel wire rope 5, and a fixing nut 6. The steel sample block 4 is fixedly connected to the steel wire rope 5 by the fixing nut 6.

[0023] In some embodiments, the slot assembly 1 has an inverted "T" shaped cross section, which can fit precisely into the groove provided on the tensile testing machine 12.

[0024] In some embodiments, the limiting mechanism includes a limiting block 3 and a locking block 10. There are two locking blocks 10, which are respectively located at both ends of the limiting block 3. The outline of the limiting block 3 fits and abuts against the outer outline of the wheel hub. The locking block 10 has an "L" shaped structure and engages with the wheel hub to further position and limit the wheel hub.

[0025] Example: Based on the groove on the bottom plane of the existing tensile testing machine 12, the designed base plate 9 is clamped in the groove, the car wheel hub 11 is placed on the pad 8, and the car wheel hub 11 is fixed by the limiting mechanism on the pad 8. The height of the pad 8 is adjusted by rotating the rotating nut group 2, mainly to tilt it, until the wheel logo sticker 13 is in a horizontal position. Then, the bottom end of the connecting fixture is coated with glue and evenly adhered to the logo sticker 13. The upper end of the connecting fixture is connected to the hook of the tensile testing machine 12. After the connection is completed, the tensile testing machine 12 is pulled up by setting the pulling speed until the force value at the moment the logo sticker 13 falls off is displayed, which is determined as the viscosity of the logo sticker 13. The limiting mechanism on the welded end of the pad 8 is made of nylon material, mainly to prevent the car wheel hub 11 from moving, and the nylon material will not scratch the wheel during the limiting process.
