Description
Technical Field
[0001] The utility model relates to the technical field of inspection tools, in particular to an EPP automobile seat back inspection tool. Background Art
[0002] EPP is the abbreviation of expanded polypropylene. It has the advantages of light weight, heat insulation, cushioning, insulation, corrosion resistance, and low price. Therefore, it is widely used in daily necessities, packaging, industry, agriculture, transportation, and aerospace industries. The seat backs of many cars are made of metal as the skeleton and are filled with foamed polypropylene. After filling with foamed polypropylene, the car seat backs need to undergo corresponding quality inspections.
[0003] Existing EPP car seat back inspection fixtures generally fix multiple quick clamps and mounting brackets on a base. The seat assembly is then installed on the mounting bracket and clamped with the quick clamps. Measurements are then performed using a magnetic gauge base and a micrometer. However, the magnetic gauge base must be adjusted first, which increases the measurement time. Utility Model Content
[0004] Based on this, the purpose of the present invention is to provide an EPP car seat back gauge to solve the technical problem that the magnetic base needs to be adjusted first during measurement, which makes the entire measurement time longer.
[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solution: an EPP automobile seat back inspection fixture, comprising a base plate, a mounting frame fixedly connected to the top of the base plate, a plurality of positioning blocks fixedly connected to the mounting frame for positioning, a first connecting mechanism sleeved on the positioning block, the first connecting mechanism comprising a first set of blocks, a horizontal plate fixedly connected to the top of the first set of blocks, a first bearing fixedly connected to the horizontal plate, a micrometer arranged inside the first bearing.
[0006] By adopting the above technical solution, a solid foundation is provided for the entire EPP car seat back inspection fixture by fixedly connecting the base plate and the mounting frame. Several positioning blocks fixedly connected to the mounting frame provide precise positioning points for the seat assembly. These positioning blocks are welded according to the shape and size of the seat, ensuring that the seat remains in the correct position during the measurement process, avoiding measurement errors caused by position deviation.
[0007] Furthermore, a mounting groove is provided at the top of the positioning block, and a magnet is fixedly connected to the inside of the mounting groove, and the magnet is used to attract the first set of blocks.
[0008] By adopting the above technical solution, by opening a mounting groove at the top of the positioning block and fixing a connecting magnet therein, the connection stability between the first connecting mechanism and the positioning block is enhanced. The attraction of the magnet can ensure that the first set of blocks fits tightly on the positioning block. Even if it is disturbed by external forces during the measurement process, it can maintain a stable connection state, thereby improving the accuracy and reliability of the measurement.
[0009] Furthermore, a groove is provided inside the first set of blocks, and the groove is adapted to fit the positioning block.
[0010] By adopting the above technical solution and providing a groove adapted to the positioning block inside the first set block, it is ensured that the first connecting mechanism can be tightly and accurately sleeved on the positioning block.
[0011] Furthermore, the positioning block is sleeved with a second connecting mechanism, and the second connecting mechanism includes a second sleeve block.
[0012] By adopting the above technical solution, by arranging a second connecting mechanism on the positioning block, and the second connecting mechanism including a second set of blocks, a more flexible and diverse measurement method is provided for the EPP automobile seat back inspection fixture. The second connecting mechanism can complement the first connecting mechanism to jointly meet the measurement requirements of different positions and angles, thereby improving the applicability and measurement range of the inspection fixture.
[0013] Furthermore, one side of the second set of blocks is connected to a connecting rod via a plug post, and one end of the connecting rod is connected to a bending plate via a socket.
[0014] By adopting the above technical solution, by providing a plug-in column on one side of the second set of blocks and connecting it to the connecting rod, the second connecting mechanism is made more flexible and variable in structure. The connecting rod can be selected to different lengths according to measurement requirements, or the position of the measurement point can be adjusted by replacing connecting rods of different lengths, thereby meeting measurement requirements at different locations and depths on the seat back. This greatly improves measurement flexibility and accuracy.
[0015] Furthermore, second bearings are provided on both side surfaces of the bending plate, and a micrometer is provided inside the second bearing.
[0016] By adopting the above technical solution, by arranging second bearings on both sides of the bent plate and installing a micrometer inside the second bearing, the accuracy and flexibility of measurement are improved.
[0017] Furthermore, a clamp is connected to the base plate via bolts, and a replaceable pressure column is clamped inside the clamp.
[0018] By adopting the above technical solution, the clamp is connected to the base plate by bolts, so that the inspection tool can conveniently carry and store replacement pressure columns. The clamp serves as a fixing device for the pressure column, allowing the operator to quickly find and replace the pressure column, thereby improving the efficiency and convenience of measurement.
[0019] In summary, the present invention has the following beneficial effects:
[0020] 1. The present invention ensures the stability of the entire measurement system by providing a first connecting mechanism, providing a reliable foundation for subsequent accurate measurements. The seat assembly is clamped using a quick clamp, which not only simplifies the clamping process but also improves measurement efficiency and ensures the stability of the seat during the measurement process. Positioning blocks of appropriate height are welded to the mounting frame corresponding to the position of the seat to be measured, providing an accurate positioning reference for measurement. After selecting a positioning block at a certain location, the first set of blocks of the first connecting mechanism is placed on the corresponding positioning block, and the attraction of the magnet ensures a stable connection and accurate measurement. The reading on the dial indicator can directly reflect the data to be measured, realizing rapid detection of the seat edge and greatly improving measurement efficiency.
[0021] 2. The utility model provides great flexibility and convenience for measuring different batches of seats by setting up a second connecting mechanism. The operator can quickly select appropriate connecting rods and bent plates for assembly according to specific measurement requirements. Modularity not only simplifies the preparation work before measurement, but also improves the adaptability and accuracy of measurement. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0028] The following describes an embodiment of the present invention based on its overall structure.
[0029] Example 1:
[0030] An EPP car seat back inspection fixture, such as Figures 1-4 As shown, it includes a base plate 1, a mounting frame 2 is fixedly connected to the top of the base plate 1, a number of positioning blocks 3 are fixedly connected to the mounting frame 2 for positioning, a first connecting mechanism 4 is sleeved on the positioning block 3, the first connecting mechanism 4 includes a first set of blocks 401, a horizontal plate 402 is fixedly connected to the top of the first set of blocks 401, a first bearing 403 is fixedly connected to the horizontal plate 402, a micrometer 404 is arranged inside the first bearing 403, the first set of blocks 401 can be tightly sleeved on the positioning block 3, and the stability of the connection is ensured by magnets, the setting of the horizontal plate 402 and the first bearing 403 provides a stable support for the micrometer 404, and the first bearing 403 enables the micrometer 404 to rotate in the horizontal plane for more accurate observation and recording.
[0031] See Figure 2 and Figure 3 A mounting groove 5 is provided at the top of the positioning block 3, and a magnet 6 is fixedly connected to the inside of the mounting groove 5. The magnet 6 is used to attract the first set of blocks 401. This magnetic adsorption connection method also makes the disassembly and assembly of the first connecting mechanism 4 very simple. When it is necessary to measure different positions on the seat, the operator only needs to easily pull out the first connecting mechanism 4 from the current positioning block 3 and then move it to another positioning block without the need for complicated fixing and adjustment processes.
[0032] See Figure 2 and Figure 3 A groove 405 is provided inside the first set of blocks 401, and the groove 405 is adapted to the positioning block 3. The groove 405 also makes it easier to install and remove the first connecting mechanism 4 on the positioning block 3. The operator only needs to align the first set of blocks 401 with the positioning block 3, and then gently push it in or pull it out, without the need for complicated adjustment or fixing process.
[0033] See Figure 1 A clip 8 is connected to the base plate 1 by bolts, and a replaceable pressure column 9 is engaged inside the clip 8. The bolt connection method also allows the position of the clip 8 on the base plate 1 to be adjusted according to actual needs, ensuring that the pressure column 9 can be placed in a suitable position.
[0034] The implementation principle of the utility model is as follows: first, place the base plate 1 steadily on the workbench to ensure that it is stable and does not shake, place the seat in the mounting frame 2 on the base plate 1, and use a quick clamp to clamp the seat assembly;
[0035] Weld a positioning block 3 of appropriate height at the relative position of the mounting frame 2 at the position of the seat to be measured;
[0036] Select a positioning block 3 at a certain location, and then use the first set block 401 of the first connecting mechanism 4 to cover the corresponding positioning block 3. Use the attraction of the magnet 6 to ensure a stable connection. Use the top surface of the positioning block 3 as the positioning surface to ensure the accuracy of the measurement. At this time, the reading on the dial indicator 404 is the reading to be measured.
[0037] Turn the dial indicator 404 so that the surface of the dial indicator 404 faces you, making it easier to read the dial indicator.
[0038] After the reading is completed, the first connecting mechanism 4 is pulled out and then inserted into different positioning blocks 3 for measurement. By using a fixed first connecting mechanism 4, it is only necessary to weld different positioning blocks 3 at the beginning, so that the edge can be quickly detected.
[0039] If the pressure column 9 of the quick clamp is worn, just loosen the bolts on the clamp 8, take out the old pressure column 9, replace it with a new one, and retighten the bolts.
[0040] Example 2:
[0041] See Figure 4 A second connecting mechanism 7 is sleeved on the positioning block 3, and the second connecting mechanism 7 includes a second set of blocks 701. The second set of blocks 701 enables the second connecting mechanism 7 to be easily sleeved on the positioning block 3, and ensures the stability of the connection through magnetic adsorption, which simplifies the installation and disassembly process of the second connecting mechanism 7, and also enables the operator to quickly replace or adjust the connecting mechanism as needed, thereby improving the measurement efficiency. For some batches of seat components, it may not be possible to directly use the first connecting mechanism 4 for measurement. However, due to its flexibility and diversity, the second connecting mechanism 7 can adapt to the measurement requirements of these seat components by adjusting its structure and position, thereby broadening the application range of the inspection fixture.
[0042] See Figure 4 One side of the second set of blocks 701 is connected to a connecting rod 703 through a plug post 702, and one end of the connecting rod 703 is connected to a bending plate 705 through a socket 704. The connection method between the plug post 702 and the socket 704 also makes the assembly and disassembly of the second connecting mechanism 7 easier. The operator can quickly replace or adjust the connecting rod 703 and the bending plate 705 according to the measurement requirements without the need for complicated tools or steps.
[0043] See Figure 4 A second bearing 706 is provided on both sides of the bending plate 705, and a micrometer 404 is provided inside the second bearing 706. The operator can choose different directions to measure the seat back, which increases the measurement range and thus improves the measurement accuracy, providing more comprehensive data support for quality control.
[0044] The implementation principle of the present invention is as follows: First, when it is necessary to use a different batch of seats for measurement, the second connecting mechanism 7 is used. According to the measurement requirements, the appropriate connecting rod 703 and bent plate 705 are selected for assembly. The assembled second connecting mechanism 7 is connected to the dial indicator 404 through the plug post 702 and the socket 704. By replacing a different connecting rod 703, the dial indicator 404 can be positioned at the point to be measured on the seat;
[0045] This allows full use of the positioning blocks 3 welded for the first time, avoiding the need to re-weld the positioning blocks 3 each time a different batch of seats is used.
[0046] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.
[0047] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
