Description

Technical Field

[0001] This utility model relates to the field of mechanical testing and measurement technology, and in particular to a modular inspection tool that can quickly switch testing standards. Background Technology

[0002] Currently, in the industrial manufacturing sector, the inspection of many components relies on specialized inspection fixtures. However, traditional fixtures are typically designed for a single inspection datum, making it difficult to meet the rapid switching requirements of various part types. In actual production, different parts often require different inspection datums, so changing fixtures or adjusting datums consumes a significant amount of time, impacting overall efficiency. Furthermore, traditional fixtures are mostly fixed in structure, lacking modular design, resulting in insufficient flexibility when dealing with complex inspection tasks. Because the inspection process demands high precision, frequent fixture changes or adjustments can lead to error accumulation, affecting product quality. Simultaneously, operators need to repeatedly calibrate traditional fixtures, increasing workload and operational difficulty, further reducing production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a modular inspection tool that can quickly switch inspection standards, thus solving the problems mentioned in the background art.

[0004] This invention is implemented as follows: a modular fixture capable of quickly switching detection benchmarks. The fixture mainly consists of a benchmark switching component, a modular detection unit, and a mounting bracket. The benchmark switching component is located on top of the mounting bracket and is used to achieve rapid switching between different detection benchmarks. The modular detection unit is connected to the mounting bracket via a sliding connection and can be replaced or adjusted according to detection requirements. The mounting bracket, as the supporting body of the overall structure, has multiple positioning holes and guide grooves for fixing the components and ensuring their positional accuracy.

[0005] The reference switching assembly includes a rotating disk, locating pins, and a drive handle. The rotating disk is disc-shaped with multiple evenly distributed reference locating slots on its outer circumference, each corresponding to a different detection reference. The center of the rotating disk is connected to a rotating shaft at the top of the mounting bracket via a bearing, allowing the disk to rotate freely in the horizontal plane. The locating pin is vertically positioned below the rotating disk and engages with a locating hole on the mounting bracket via a spring mechanism. When the rotating disk rotates to align with a specific reference locating slot, the locating pin automatically pops out and inserts into the corresponding locating hole, thus locking the reference. The drive handle is fixed to one side of the rotating disk; the operator rotates the drive handle to rotate the rotating disk and switch between different detection references.

[0006] The modular testing unit includes a testing module, sliders, and a locking device. The testing module is detachable and features a groove at its bottom that matches a guide groove on the mounting bracket, allowing the module to slide and position itself along the guide groove. Slider blocks are located on both sides of the testing module and are fixedly connected to it with bolts. The outer side of the slider has protrusions that embed into the guide grooves on the mounting bracket, ensuring stability during sliding. The locking device includes a locking screw and a pressure plate. The locking screw passes through the mounting bracket and connects to the pressure plate. When the testing module slides to the target position, rotating the locking screw causes the pressure plate to press the testing module into place, thus securing it.

[0007] The mounting bracket has a frame structure with a base plate at the bottom. Multiple mounting holes on the base plate are used to fix the inspection fixture to the worktable. Vertical support plates are located on both sides of the mounting bracket, connected by crossbeams to form a stable support frame. The inner surface of the support plates is machined with guide grooves, which have a "T"-shaped cross-section to mate with the protrusions of the slider, ensuring precise and controllable sliding trajectory of the inspection module. Furthermore, the top of the mounting bracket has a rotating shaft seat with embedded bearings to support the rotating disk of the reference switching component, allowing it to rotate smoothly.

[0008] This invention solves the problem of traditional gauges' difficulty in quickly switching inspection references through the design of a reference switching component. The cooperation between the reference positioning groove and the positioning pin on the rotating disk achieves precise positioning of the reference, while the drive handle simplifies the operation process and improves switching efficiency. The introduction of modular inspection units allows the gauge to adapt to various inspection tasks, and the combination of the sliding connection method and locking device of the inspection modules ensures stability and accuracy during the inspection process. The frame structure of the mounting bracket not only provides sufficient support strength but also ensures the assembly accuracy of each component through the design of guide grooves and positioning holes.

[0009] This invention features a simple and rational structural design with clear connections between components, facilitating manufacturing and assembly. Through the synergistic effect of the reference switching component and the modular inspection unit, the flexibility and efficiency of the inspection fixture are significantly improved, reducing the time and labor costs required for frequent fixture changes or adjustments. Simultaneously, the modular design reduces the risk of error accumulation and improves the reliability of inspection results, thus providing strong support for quality control in the industrial manufacturing sector.

[0014] like Figures 1 to 2 As shown, this utility model provides a modular inspection fixture that can quickly switch inspection references, which mainly consists of a reference switching component, a modular inspection unit, and a mounting bracket 4. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0015] Mounting bracket 4 serves as the main support for the entire fixture. It has a frame structure with a base plate at the bottom, featuring multiple mounting holes for fixing the fixture to the workbench. Vertical support plates are located on both sides of the mounting bracket 4, connected by crossbeams to form a stable support frame. Guide grooves 9, with a "T"-shaped cross-section, are machined on the inner surface of the support plates to engage with the protrusions of the slider 6. A rotating shaft seat with embedded bearings is located at the top of the mounting bracket 4 to support the rotating disk 1 of the reference switching assembly, ensuring smooth rotation. Multiple positioning holes 10 are also provided at the top of the mounting bracket 4 to engage with the positioning pins 2 in the reference switching assembly, enabling the reference to be locked.

[0016] The reference switching assembly is located on the top of the mounting bracket 4 and includes a rotating disk 1, a positioning pin 2, and a drive handle 3. The rotating disk 1 is disc-shaped, and its center is connected to the rotating shaft at the top of the mounting bracket 4 via a bearing, allowing the rotating disk 1 to rotate freely in the horizontal plane. Multiple reference positioning grooves are evenly distributed around the outer circumference of the rotating disk 1, each corresponding to a different detection reference. The positioning pin 2 is vertically positioned below the rotating disk 1 and engages with the positioning hole 10 on the mounting bracket 4 via a spring mechanism. When the rotating disk 1 rotates until a reference positioning groove aligns with the positioning hole 10 on the mounting bracket 4, the positioning pin 2 automatically pops out under the action of the spring and inserts into the corresponding positioning hole 10, thereby locking the reference. The drive handle 3 is fixed to one side of the rotating disk 1. The operator can rotate the rotating disk 1 by rotating the drive handle 3 to switch between different detection references. The rotation range of the rotating disk 1 is limited by the limiting structure at the top of the mounting bracket 4 to ensure that the reference positioning groove accurately aligns with the positioning hole 10 after each rotation.

[0017] The modular detection unit is connected to the mounting bracket 4 via a sliding connection and includes a detection module 5, a slider 6, and a locking device. The detection module 5 is detachable and has a groove at its bottom that matches the guide groove 9 on the mounting bracket 4, allowing the detection module 5 to slide and be positioned along the guide groove 9. The slider 6 is located on both sides of the detection module 5 and is fixedly connected to it by bolts. The outer side of the slider 6 has a protrusion that embeds into the guide groove 9 on the mounting bracket 4 to ensure stability of the detection module 5 during sliding. The locking device includes a locking screw 7 and a pressure plate 8. The locking screw 7 passes through the mounting bracket 4 and connects to the pressure plate 8. When the detection module 5 slides to the target position, rotating the locking screw 7 causes the pressure plate 8 to press the detection module 5, thus fixing it in place. The sliding range of the detection module 5 is determined by the length of the guide groove 9 on the mounting bracket 4. Stop structures are provided at both ends of the guide groove 9 to prevent the detection module 5 from sliding out.

[0018] In practical applications, the operator first selects a suitable detection module 5 according to the testing requirements and installs it onto the mounting bracket 4. The detection module 5, through the protrusion of the slider 6, engages with the guide groove 9 on the mounting bracket 4. After sliding along the guide groove 9 to the target position, the locking screw 7 is rotated to press the pressure plate 8 against the detection module 5, thus fixing the detection module 5. Subsequently, according to the required testing benchmark, the operator rotates the drive handle 3 to rotate the rotating disk 1, aligning the benchmark positioning groove on the rotating disk 1 with the positioning hole 10 on the mounting bracket 4. Once aligned, the positioning pin 2 automatically pops out under the action of a spring and inserts into the positioning hole 10, thereby locking the benchmark. At this point, the inspection fixture has completed the switching of the testing benchmark and can perform the corresponding testing operations.

[0019] During the inspection process, the positional accuracy of the inspection module 5 is ensured by the cooperation of the guide groove 9 on the mounting bracket 4 and the protrusion of the slider 6, while the stability of the inspection module 5 is provided by the locking device. The cooperation between the rotary disk 1 and the positioning pin 2 in the reference switching assembly ensures the accurate positioning of the inspection reference, while the setting of the drive handle 3 simplifies the reference switching operation process. The frame structure of the mounting bracket 4 provides sufficient support strength for the entire fixture, while the design of the guide groove 9 and the positioning hole 10 ensures the assembly accuracy of each component.

[0020] This utility model's inspection fixture is applicable to various industrial manufacturing scenarios, such as dimensional inspection of automotive parts and geometric tolerance inspection of machined parts. In these applications, the fixture can quickly switch between different inspection benchmarks and adapt to different inspection tasks through the replacement of modular inspection units. For example, when inspecting a batch of parts with different specifications, the operator only needs to replace the corresponding inspection module 5 and adjust the benchmark switching component to complete the inspection preparation, significantly improving inspection efficiency. Furthermore, the modular design reduces the risk of error accumulation and improves the reliability of inspection results, thus providing strong support for quality control in the industrial manufacturing field.

[0021] The present invention features a simple and reasonable structural design with clear connections between components, facilitating manufacturing and assembly. Through the synergistic effect of the reference switching component and the modular detection unit, the flexibility and efficiency of the inspection fixture are significantly improved, reducing the time and labor costs required for frequent fixture replacement or adjustment.

[0022] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0023] In the automotive parts manufacturing industry, it is necessary to perform dimensional inspection on a batch of parts with different specifications. The operator first fixes the mounting bracket 4 to the workbench through the mounting holes on the base plate, ensuring the overall stability of the inspection fixture. Then, a suitable inspection module 5 is selected according to the type of part to be inspected, and its bottom groove is aligned with the guide groove 9 on the mounting bracket 4. The protrusion of the slider 6 is embedded in the guide groove 9, allowing the inspection module 5 to slide smoothly along the guide groove 9. Once the inspection module 5 has slid to the target position, the operator rotates the locking screw 7, causing the pressure plate 8 to press the inspection module 5, completing its fixation. During this process, the "T"-shaped cross-section of the guide groove 9 and the protrusion of the slider 6 closely cooperate, ensuring the positional accuracy of the inspection module 5.

[0024] Next, the operator adjusts the reference switching component according to the testing requirements. Rotating the drive handle 3 drives the rotating disk 1 to rotate, causing the reference positioning slots on the rotating disk 1 to move accordingly. When a reference positioning slot aligns with the positioning hole 10 on the top of the mounting bracket 4, the positioning pin 2 automatically pops out under the action of a spring and inserts into the positioning hole 10, thus locking the reference. At this time, the multiple reference positioning slots evenly distributed on the outer circumference of the rotating disk 1 ensure rapid switching between different testing references, while the presence of the limiting structure ensures that the reference positioning slot accurately aligns with the positioning hole 10 after each rotation.

[0025] During the testing process, the operator places the part to be tested on the testing module 5 and measures it according to the locked testing benchmark. Since the sliding trajectory of the testing module 5 is precisely controlled by the guide groove 9, and its stability is ensured by the locking device, errors caused by module loosening or positional misalignment are effectively avoided. Simultaneously, the cooperation between the rotating disk 1 and the positioning pin 2 in the benchmark switching assembly ensures accurate positioning of the testing benchmark, further improving the reliability of the testing results.

[0026] If a change of inspection task is required, such as switching from inspecting the dimensions of one part to inspecting the form and position tolerances of another, the operator only needs to replace the corresponding inspection module 5 and readjust the datum switching component to complete the preparation. This process significantly reduces the time and labor costs required for frequent changes or adjustments to traditional inspection fixtures. Furthermore, the modular design reduces the risk of error accumulation due to multiple changes or adjustments, thus providing strong support for quality control in the industrial manufacturing sector.
