Description

Technical Field

[0001] This utility model relates to the field of automotive production inspection tool technology, and in particular to an inspection tool for the left front and right front and rear carpet assembly. Background Technology

[0002] The development of automotive carpet assembly inspection fixtures stems from the limitations of traditional manual inspection methods. In existing technologies, the inspection of automotive carpets, especially the left and right front / rear carpets, largely relies on manual visual inspection and measurement, which suffers from unstable positioning, low inspection efficiency, and difficulty in guaranteeing accuracy. Due to the flexible nature of carpets, traditional inspection methods are prone to displacement due to incomplete fixation, affecting the accuracy of measurements of key parameters such as contour and mounting hole positions. Furthermore, with the increasing quality requirements of automotive interiors, the multi-layered composite structure of carpets, including sound insulation layers and skeleton layers, places higher demands on inspection, necessitating specialized fixtures to achieve rapid positioning and integrated multi-dimensional parameter inspection. Against this backdrop, the development of specialized fixtures with rapid clamping, cavity positioning, and dynamic inspection functions has become an inevitable requirement for technological upgrading in the industry.

[0003] A rear carpet assembly inspection tool is disclosed in utility model application number 202220073194.8. By designing an inspection table, quick clamps, limiting blocks, and inspection structures are respectively set on the top of the inspection table, which facilitates the placement of the car rear carpet in the inspection slot of the inspection table. The quick clamps and limiting blocks are used to limit the car rear carpet, and the inspection structure is used to inspect the car rear carpet. This not only makes it easier for staff to inspect the car rear carpet, but also improves the accuracy of the car rear carpet inspection and improves the quality of the car rear carpet.

[0004] However, the aforementioned rear carpet assembly inspection fixture requires manual assistance to align the rear carpet with the limiting block when positioning the car's rear carpet, which requires a considerable amount of time to adjust the position of the rear carpet before inspection, easily affecting inspection efficiency. In addition, the aforementioned rear carpet assembly inspection fixture requires operators to manually take inspection readings using feeler gauges or gap gauges, and manual measurement is prone to mis-inspection and omission, affecting the inspection results. Therefore, this utility model proposes a carpet assembly inspection fixture for the left front and right front and rear carpets to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to propose a carpet assembly inspection tool for the left front and right front and rear sides. This tool automatically guides and positions the carpet assembly through the cooperation of a slide rail and a positioning bucket. Combined with the precise alignment of the positioning reference hole and the reference post, it effectively avoids manual adjustment steps, significantly improving inspection efficiency. The inspection mechanism, which integrates a pressure sensor and a feeler gauge, can monitor the changes in gap pressure in real time, accurately judge the dimensional compliance, and provide reliable inspection results. It solves the problems of cumbersome and time-consuming traditional manual positioning, and balances high efficiency, accuracy, and portability.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a carpet assembly inspection fixture for the left front and right front and rear, including a chassis, an inspection fixture body, an auxiliary positioning mechanism, a positioning clamping mechanism, and a detection mechanism. The inspection fixture body is fixedly mounted in the middle of the chassis. The auxiliary positioning mechanism includes a slide rail, a sliding frame, a positioning bucket, a carpet assembly, positioning reference holes, a detection groove, and a positioning reference post. The slide rail is symmetrically fixedly mounted on the chassis, and the sliding frame is slidably mounted on the slide rail. The positioning bucket is symmetrically fixedly mounted on one side of the sliding frame, and the carpet assembly is inserted into the positioning bucket. The carpet assembly has positioning reference holes at its four corners.

The positioning clamping mechanism is located on the lower side of the other side of the sliding frame, and the detection mechanism is located on the lower side of the other side of the sliding frame.

[0007] A further improvement is that the positioning bucket corresponds to the upper and lower positions of the detection groove, and the positioning reference hole corresponds to the upper and lower positions of the positioning reference column.

[0008] A further improvement is that the positioning and clamping mechanism includes a bracket, an electric telescopic rod, a lifting frame, and a positioning block. A bracket is fixedly provided on the lower side of the other side of the sliding frame. An electric telescopic rod is symmetrically fixed on the bracket. A lifting frame is fixedly provided at the telescopic end of the electric telescopic rod. A positioning block is symmetrically fixed at the bottom of the lifting frame. A detection mechanism is provided below the lifting frame.

[0009] A further improvement is that the positioning blocks correspond to the upper and lower positions of the detection grooves, and multiple sets of positioning blocks are arranged.

[0010] A further improvement is that the detection mechanism includes a detection chamber, a pressure sensor, a connecting block, and a feeler gauge. The detection chamber is arranged around the bottom of the lifting frame. Pressure sensors are arranged and fixed inside the detection chamber. The sensing end of the pressure sensor is fixedly connected to the connecting block. A feeler gauge is fixedly connected to the bottom center of the connecting block.

[0011] A further improvement is that the feeler gauge is located above the edge of the detection chamber, and multiple sets of pressure sensors are provided.

[0012] A further improvement is that a handle is fixedly provided on one side of the chassis, and omnidirectional wheels are fixedly provided at the four corners of the bottom of the chassis.

[0013] The beneficial effects of this utility model are as follows: This utility model achieves automatic guidance and positioning of the carpet assembly through the cooperation of the slide rail and the positioning bucket. Combined with the precise alignment of the positioning reference hole and the reference column, it effectively avoids manual adjustment steps and significantly improves detection efficiency. The detection mechanism integrating pressure sensor and feeler gauge can monitor the change of gap pressure in real time, accurately judge the size qualification, and the detection results are reliable. It solves the problems of cumbersome and time-consuming traditional manual positioning, and takes into account efficiency, accuracy and portability. Attached Figure Description

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment provides a carpet assembly inspection fixture for the left front and right front and rear sides, including a chassis 1, a fixture body 2, an auxiliary positioning mechanism, a positioning clamping mechanism, and a detection mechanism. The fixture body 2 is fixedly mounted on the center of the chassis 1. The auxiliary positioning mechanism includes a slide rail 3, a sliding frame 4, a positioning bucket 5, a carpet assembly 6, a positioning reference hole 7, a detection groove 8, and a positioning reference post 9. The slide rail 3 is symmetrically fixedly mounted on the chassis 1, and the sliding frame 4 is slidably mounted on the slide rail 3. The positioning bucket 5 is symmetrically fixedly mounted on one side of the sliding frame 4, and the carpet assembly 6 is inserted into the positioning bucket 5. The carpet assembly 6 has positioning reference holes 7 at its four corners. The inspection groove 8 is symmetrically mounted inside the fixture body 2, and the detection groove 8 has positioning reference holes 7 at its four corners. The positioning reference post 9 pushes the sliding frame 4 to slide horizontally along the slide rail 3 during testing, so that the positioning bucket 5 moves to correspond to the upper and lower positions of the testing groove 8. The carpet assembly 6 is placed into the corresponding positioning bucket 5, and the inner wall of the positioning bucket 5 guides the carpet assembly 6 into the testing groove 8. At the same time, the positioning reference post 9 passes through the positioning reference hole 7, and the positioning reference hole 7 corresponds to the upper and lower positions of the positioning reference post 9, so that the carpet assembly 6 remains stable in the testing groove 8. This facilitates the quick placement of the carpet assembly 6 into the testing groove 8 to start alignment, which solves the problem of needing manual assistance for alignment when positioning car carpets and effectively shortens the adjustment time. A positioning clamping mechanism is provided on the lower side of the other side of the sliding frame 4, and a testing mechanism is provided on the lower side of the other side of the sliding frame 4.

[0021] The positioning and clamping mechanism includes a bracket 10, an electric telescopic rod 11, a lifting frame 12, and a positioning block 13. The bracket 10 is fixedly installed on the lower side of the other side of the sliding frame 4. The electric telescopic rod 11 is symmetrically fixed on the bracket 10. The lifting frame 12 is fixedly installed at the telescopic end of the electric telescopic rod 11. The positioning block 13 is symmetrically fixed at the bottom of the lifting frame 12. A detection mechanism is provided below the lifting frame 12. Multiple sets of positioning blocks 13 are arranged. When the car carpet is aligned, the sliding frame 4 is pulled to slide along the slide rail 3 to one side, so that the positioning block 13 corresponds to the vertical position of the detection groove 8. The electric telescopic rod 11 extends to push the lifting frame 12 down, which in turn drives the positioning block 13 down to press down on the carpet assembly 6.

[0022] The testing mechanism includes a testing chamber 14, pressure sensors 15, a connecting block 16, and a feeler gauge 17. The testing chamber 14 is arranged around the bottom of the lifting frame 12. Pressure sensors 15 are arranged and fixed inside the testing chamber 14. The sensing end of the pressure sensor 15 is fixedly connected to the connecting block 16. A feeler gauge 17 is fixedly connected to the bottom center of the connecting block 16. The feeler gauge 17 is located above the edge of the testing chamber 14. There are multiple sets of pressure sensors 15. When testing is performed, the feeler gauge 17 descends synchronously with the lifting frame 12 and is inserted into the gap between the testing slot 8 and the carpet assembly 6. If the size of the carpet assembly 6 is not up to standard, the feeler gauge 17 will not be able to be inserted into the gap, causing abnormal pressure on the pressure sensor 15. This allows for easy determination of whether the size of the carpet assembly 6 is up to standard based on the pressure of the pressure sensor 15.

[0023] A handle 18 is fixedly provided on one side of the chassis 1, and casters 19 are fixedly provided at the four corners of the bottom of the chassis 1, so that the chassis 1 can be moved quickly by pushing the handle 18 in conjunction with the casters 19, thereby improving the portability of the inspection tool.

[0024] When inspecting the carpet assembly (left front, right front, back) using this carpet inspection fixture, the sliding frame is first moved along the slide rail to align the positioning bucket with the inspection slot. The carpet assembly is then placed into the positioning bucket, and automatic positioning is achieved through the cooperation of the positioning reference hole and the positioning reference post. Next, the electric telescopic rod is activated to drive the lifting frame to descend, and multiple sets of positioning pressure blocks are used to press the carpet assembly tightly. At the same time, the inspection mechanism descends with the lifting frame, and a feeler gauge is inserted into the gap between the carpet and the inspection slot. Multiple sets of pressure sensors monitor the resistance of the feeler gauge to determine the dimensional compliance. After the inspection is completed, the entire process from positioning, clamping, inspection to movement can be automated through the casters and handles on the bottom of the chassis.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
