The mounting bracket can expand or retract around the central axis of the base plate. The detection module is located on top of the mounting bracket and includes a sliding platform, a positioning block, and a detection probe. The sliding platform is connected to the top beam of the mounting bracket via a linear guide rail. A rack is located at the bottom of the sliding platform, meshing with a gear mounted on the mounting bracket. The gear is driven to rotate by a handwheel, thereby moving the sliding platform along the linear guide rail. The positioning block is fixed to the sliding platform. Multiple grooves matching the shape of the parts to be tested are formed on the surface of the positioning block. An elastic layer made of wear-resistant rubber is provided on the inner wall of the grooves to protect the surface of the parts. The detection probe is fixed to one side of the positioning block via a threaded connection. A high-precision sensor is located at the end of the detection probe, and the sensor is connected to an external display device via a data cable.

[0007] The auxiliary components include support legs, anti-slip pads, and a storage box.

[0020] This utility model discloses a lightweight, portable inspection tool for small automotive parts, the structure of which is as follows: Figure 1 As shown, the system includes a base plate 1, a mounting bracket 2, a detection module, and auxiliary components. The base plate 1 is a rectangular flat plate structure made of lightweight, high-strength aluminum alloy. Threaded holes are provided at each of its four corners for fixing or removing the mounting bracket 2. The mounting bracket 2 is a foldable frame structure composed of multiple hinged metal rods, which are fixed together by spring pins. The mounting bracket 2 can be unfolded or folded around the central axis of the base plate 1, as shown in the specific folding configuration. Figure 2 As shown. The bottom of the mounting bracket 2 is provided with positioning pins. After the positioning pins are inserted into the positioning holes evenly distributed along the edge of the surface of the base plate 1, they are locked with nuts, thereby realizing the fixed connection between the mounting bracket 2 and the base plate 1.

[0021] The detection module is located on top of the mounting bracket 2 and includes a sliding platform 3, a positioning block 4, and a detection probe 5. The sliding platform 3 is connected to the top beam of the mounting bracket 2 via a linear guide rail. A rack is installed at the bottom of the sliding platform 3, meshing with a gear mounted on the mounting bracket 2. The gear is driven to rotate via a handwheel, thus moving the sliding platform 3 along the linear guide rail. A scale 9 is installed on the top beam of the mounting bracket 2, arranged along the direction of the linear guide rail, to indicate the moving distance of the sliding platform 3, facilitating the operator to adjust the position of the sliding platform 3 according to the size of the parts. The positioning block 4 is fixed to the sliding platform 3. Multiple grooves matching the shape of the parts to be detected are formed on the surface of the positioning block 4. The inner wall of the grooves is provided with an elastic layer made of wear-resistant rubber material. The detection probe 5 is fixed to one side of the positioning block 4 via a threaded connection. A high-precision sensor is installed at the end of the detection probe 5, and the sensor is connected to an external display device via a data cable. The end of the detection probe 5 is also provided with a replaceable contact 10. The contact 10 is connected to the detection probe 5 by magnetic attraction. The material of the contact 10 is selected according to different detection requirements. For example, metal contacts are used to detect parts with high hardness, and plastic contacts are used to detect parts with easily scratched surfaces.

[0022] The auxiliary components include support legs 6, anti-slip pads 7, and storage boxes 8. Support legs 6 are telescopic, with their tops threaded to the bottom of the base plate 1. Anti-slip pads 7, made of silicone, are located on the bottom of the support legs 6. The storage box 8 is fixed to one side of the base plate 1 and is a drawer-type structure with multiple internal partitions dividing it into several independent storage areas for storing positioning blocks 4 and detection probes 5 of different sizes. A transparent observation window, made of tempered glass, is located on the outside of the storage box 8.

[0023] In actual use, first place the base plate 1 on a stable workbench, and adjust the height of the base plate 1 using the support legs 6 to ensure the inspection fixture is level. The anti-slip pad 7 effectively prevents the inspection fixture from sliding during use. Next, unfold the mounting bracket 2 from its folded state, insert the positioning pin into the positioning hole of the base plate 1, and tighten it with a nut to complete the fixed connection between the mounting bracket 2 and the base plate 1. Then, according to the shape and size of the part to be inspected, select appropriate positioning blocks 4 and inspection probes 5 from the storage box 8 and install them onto the sliding platform 3. The groove design of the positioning block 4 matches the shape of the part to be inspected, and the elastic layer prevents damage to the surface of the part during inspection.

[0024] During the inspection process, the operator drives the gear to rotate by turning the handwheel. The gear meshes with the rack at the bottom of the sliding platform 3, thereby moving the sliding platform 3 along the linear guide rail. By observing the values ​​on the scale 9, the operator can precisely adjust the position of the sliding platform 3 so that the groove of the positioning block 4 is aligned with the part to be inspected. After the end contact 10 of the inspection probe 5 contacts the surface of the part, the high-precision sensor collects data and transmits it to an external display device via a data cable, completing the inspection process. If the contact 10 needs to be replaced, simply remove the existing contact 10 from the inspection probe 5 and reinstall a new contact 10 of suitable material according to the inspection requirements.

[0025] After the inspection tool is no longer in use, the mounting bracket 2 can be folded away to reduce its space occupation. At this time, the metal rods of the mounting bracket 2 are fixed by hinged connections and spring pins, forming a compact shape, such as... Figure 2 As shown. Simultaneously, the support leg 6 is retracted and tightened, returning the positioning block 4 and detection probe 5 to their designated storage area in the storage box 8 for easy subsequent use. The transparent viewing window design allows operators to quickly check the storage status of the items inside the storage box 8 without opening it.

[0026] The entire inspection fixture operates based on the precise adjustment of the sliding platform 3 and the data acquisition function of the detection probe 5. Through a rack and pinion transmission mechanism, the sliding platform 3 can move smoothly on a linear guide rail, ensuring precise alignment between the positioning block 4 and the part to be inspected. The high-precision sensor of the detection probe 5 collects data from the surface of the part in real time and transmits it to an external display device via a data cable for operator analysis and judgment. The replaceable design of the contact 10 further enhances the applicability of the inspection fixture, enabling it to adapt to the inspection needs of parts of various materials and shapes.

[0027] The above embodiments describe in detail the specific structure and operating principle of this utility model, covering the composition, connection method, and cooperation process of the base plate 1, mounting bracket 2, detection module, and auxiliary components. Through reasonable structural design and material selection, this inspection fixture achieves the goals of lightweight and portability, while ensuring detection accuracy and ease of operation, meeting the actual needs of efficient inspection of small automotive parts.

[0028] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the operating principle and implementation steps of this utility model is provided in conjunction with specific application scenarios.

[0029] In actual testing scenarios, the base plate 1 is first placed stably on the workbench, and the height of the support legs 6 is adjusted to ensure the fixture is level. The bottom of the support legs 6 is equipped with anti-slip pads 7, whose silicone material provides sufficient friction to prevent the fixture from sliding during testing, thus ensuring the reliability of the test results. Subsequently, the operator unfolds the mounting frame 2 from its folded state. At this time, the metal rods of the mounting frame 2 are hinged and rotated around the central axis of the base plate 1. The mounting frame 2 is then fixed to the base plate 1 by inserting a locating pin into the locating hole on the surface of the base plate 1 and tightening the nut. This design not only simplifies the installation process but also significantly improves the stability of the fixture while reducing the space occupied when not in use.

[0030] Next, based on the specific shape and size of the component to be tested, the operator selects the appropriate positioning block 4 and testing probe 5 from the storage box 8. The storage box 8 is divided into multiple independent storage areas by partitions, facilitating the categorization and storage of positioning blocks 4 and testing probes 5 of different specifications. The transparent observation window design allows the operator to quickly confirm the location of the required component without opening the drawer, further improving operational efficiency. The positioning block 4 is fixed to the sliding platform 3 via a threaded connection. The grooves on its surface match the shape of the component to be tested, and the elastic layer on the inner wall effectively protects the surface of the component, preventing scratches or wear due to excessive contact pressure.

[0031] During the inspection process, the operator drives the gear to rotate by turning the handwheel. The gear meshes with the rack at the bottom of the sliding platform 3, thereby moving the sliding platform 3 smoothly along the linear guide rail. The scale 9 on the top crossbeam of the mounting bracket 2 indicates the moving distance of the sliding platform 3. The operator can precisely adjust the position of the sliding platform 3 according to the value on the scale 9, so that the groove of the positioning block 4 is completely aligned with the part to be inspected. When the end contact 10 of the inspection probe 5 contacts the surface of the part, the high-precision sensor collects data in real time and transmits it to an external display device via a data cable. The contact 10 is connected to the inspection probe 5 by magnetic attraction. Its material can be flexibly changed according to the inspection requirements. For example, metal contacts are suitable for parts with high hardness, while plastic contacts are suitable for parts with easily scratched surfaces. This design significantly enhances the applicability of the inspection fixture, enabling it to meet a variety of inspection needs.

[0032] When contact 10 needs to be replaced, the operator simply removes the existing contact 10 from the testing probe 5 and reinstalls a new contact 10 of suitable material according to the testing requirements. This process is simple and quick, requiring no additional tools, further improving the ease of operation of the inspection fixture. After testing, the operator can fold and retract the mounting bracket 2 through reverse operation. The metal rods are connected by hinges and fixed by spring pins to form a compact shape, such as... Figure 2As shown. At the same time, the support leg 6 is retracted and tightened, and the positioning block 4 and detection probe 5 are returned to the designated storage area of ​​the storage box 8 for easy subsequent use.

[0033] The core of the entire inspection process lies in the precise adjustment of the sliding platform 3 and the data acquisition function of the inspection probe 5. Through a rack and pinion transmission mechanism, the sliding platform 3 can move smoothly on the linear guide rail, ensuring precise alignment between the positioning block 4 and the part to be inspected. The high-precision sensor of the inspection probe 5 collects data from the surface of the part in real time and transmits it to an external display device via a data cable for operator analysis and judgment. Furthermore, the base plate 1 is made of lightweight, high-strength aluminum alloy, combined with the foldable mounting bracket 2 structure, significantly reducing the overall weight of the inspection fixture while improving portability, making it adaptable to the actual needs of frequently changing inspection locations.

[0034] In summary, this utility model, through reasonable structural design and material selection, achieves the goals of lightweighting and portability while ensuring testing accuracy and ease of operation, providing reliable technical support for the efficient testing of small automotive parts. The above implementation steps describe in detail the operating principle and process of the inspection tool in specific application scenarios, covering the entire process from installation and testing to storage, fully demonstrating the technical advantages of this utility model.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
