Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a flatness testing mechanism and a fixed frame production system. Background Technology

[0002] In the transmission system of an air conditioner, the upper and lower fixed frames serve as the basic framework. Through their guide rails, they provide precise guidance and support for moving parts (such as gears and connecting rods), ensuring smooth transmission and coaxiality. Existing upper and lower fixed frames are typically injection molded from high-crystallinity engineering plastics. While this material offers enhanced properties, it is corrosive to mold steel. During long-term mass production, mold corrosion can easily lead to substandard flatness of the guide rails in the fixed frames. The flatness of the guide rails directly affects the fitting accuracy of moving parts. In particular, even minor deformations or dimensional deviations in the guide rails can increase transmission clearance, causing noise, vibration, or even functional failure. Therefore, the flatness of the guide rails on the fixed frames needs to be inspected during the production process.

[0003] Existing methods for detecting the flatness of guide rail grooves include: (1) indirectly inferring the internal flatness by measuring the deformation of the outer periphery of the guide rail groove with a flat feeler gauge. This method suffers from the accumulation of secondary tolerance errors, and the flat feeler gauge cannot be perfectly matched with the surface of the guide rail groove, resulting in insufficient measurement accuracy. (2) measuring the dimensions at both ends of the guide rail groove with calipers. However, this method can only determine the deformation at both ends of the guide rail groove, but cannot effectively detect the middle area of ​​the guide rail groove.

[0004] Therefore, it is necessary to improve the existing methods for detecting the flatness of guide rail grooves in order to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a flatness detection mechanism. The detection component of this mechanism can rotate on the base, thereby enabling comprehensive detection of products in different positions, which helps to improve the detection efficiency and accuracy of products, and thus improve product quality.

[0006] A flatness testing mechanism includes a base, on which a product placement position is provided;

[0007] The base is provided with a locking component for fixing the product to be tested, and the locking component is located on one side of the placement position;

[0008] The base is also provided with a detection component, which includes a detection element. The detection element is disposed above the placement position and facing the placement position, and the detection element is pivotally connected to the base.

[0009] During operation, this testing mechanism places the product to be tested in the designated spot and secures it firmly using locking mechanisms. The testing component then inspects a specific location on the product from its initial position. Controlling the component's rotation around a pivot point on the base, the component continuously monitors the flatness of different locations on the product. If the data exceeds a preset tolerance, the operator marks the product as defective. This testing mechanism allows for rapid and comprehensive inspection of products in the designated spot through component rotation, improving testing efficiency. It also enables quick completion of testing tasks, matching the production schedule and preventing delays in the testing process from impacting overall production progress, thus improving factory efficiency and capacity. Furthermore, the component's 360-degree rotation on the base ensures comprehensive inspection of all product locations, eliminating any potential flatness issues and further enhancing accuracy. In contrast, manual inspection is prone to errors due to variations in operator technique and experience. For example, when using measuring tools to check flatness, inaccurate measurement angles and reading errors may occur. Our testing organization uses high-precision displacement sensors as the testing components, and the controller precisely controls the rotation of the testing components and data acquisition, which can avoid errors caused by manual testing and improve the accuracy of testing.

[0010] In a preferred embodiment of this invention, a rotating base is provided on the base, the rotating base is pivotally connected to the base, and the detection element is connected to the rotating base via a swing rod.

[0011] In a preferred embodiment of this utility model, the top of the rotating base is provided with a mounting groove, the swing arm has a first end and a second end opposite to each other, the first end of the swing arm is hinged to the mounting groove by a pin, and the detection element is provided at the second end of the swing arm;

[0012] A pressure block is provided at the top of the mounting slot, and the pressure block is located above the swing arm.

[0013] Specifically, first, the rotating base is mounted on the base via a pivot, ensuring smooth rotation and that the clearance meets design requirements. Then, within the mounting slot of the rotating base, the first end of the swing arm is hinged to the mounting slot using a pin, adjusting the swing arm's range of motion to allow for flexible swinging. Next, the test piece is mounted on the second end of the swing arm and securely fixed using a threaded connection or a special clamp. Finally, a pressure block is installed at the top of the mounting slot, connected to the rotating base via bolts. The position of the pressure block is adjusted to provide appropriate pressure on the swing arm, preventing it from wobbling during testing without affecting its normal swinging motion.

[0014] During use, the product to be tested is placed in the designated position on the base and fixed in place; the rotating base is rotated manually or by a drive device (such as a motor driving a gear and rack mechanism), and the rotating base drives the swing arm and the test piece to rotate around the product; during the rotation, the contact of the test piece (dial indicator) contacts the product surface, and the swing arm swings according to the changes in the flatness of the product surface. The dial indicator measures and displays the flatness data of different positions of the product in real time; the operator judges whether the product meets the flatness standard by observing the data of the dial indicator. If it exceeds the standard range, the product is marked or recorded.

[0015] The pendulum arm and rotating base are hinged together by a pin, allowing the pendulum arm to swing freely within a certain angle range. This design can adapt to products of different shapes and sizes. When inspecting different types of fixtures, the pendulum arm can automatically adjust its angle according to the surface undulations and shape changes of the product, ensuring that the sample being inspected always maintains good contact with the product surface, achieving accurate inspection without the need for frequent changes in inspection equipment or adjustments to the inspection position, thus improving the versatility and flexibility of the inspection.

[0016] In a preferred embodiment of this invention, the detection element is a displacement sensor, and the bottom of the displacement sensor is provided with a contact, which is positioned towards the placement location.

[0017] In a preferred embodiment of this invention, the displacement sensor is any one of a mechanical dial indicator, an electronic displacement sensor, or a laser rangefinder.

[0018] Specifically, mechanical dial indicators can achieve an accuracy of 0.01mm, which is significantly more precise than traditional simple measuring tools (such as ordinary rulers, which typically have an accuracy of 1mm) in measuring the flatness of the fixture. In fixture production, even minute flatness deviations can affect subsequent assembly accuracy and product performance. Using mechanical dial indicators for inspection can control flatness deviations within a very small range, ensuring that the fixture quality meets high-precision requirements and improving the overall product quality.

[0019] In a preferred embodiment of this invention, a fixing block is provided at the second end of the swing arm, and a clamp is detachably provided on the fixing block, with the detection component clamped on the clamp.

[0020] In practical applications, when assembling the testing mechanism, the fixing block is first installed at the second end of the swing arm using bolts to ensure a secure connection between the fixing block and the swing arm. After connection, the mounting plane of the fixing block is perpendicular to the swing arm to ensure the perpendicularity of the test piece after installation. After installation, a suitable fixture is selected based on the size and shape of the selected test piece (such as a mechanical dial indicator, electronic displacement sensor, or laser rangefinder).

[0021] During the production of mounting frames, as product models are updated or quality standards are raised, it may be necessary to replace the inspection components with different precision or types. The detachable fixture design allows for quick replacement of these components. For example, when more precise testing of a high-precision mounting frame is required, the original mechanical dial indicator can be replaced with a more accurate electronic displacement sensor without requiring a large-scale modification of the entire inspection mechanism. This significantly improves the versatility of the inspection equipment and reduces equipment upgrade costs. This application also allows for the design of specialized fixtures for different inspection components, ensuring a tight fit and providing a stable installation environment.

[0022] In a preferred embodiment of this invention, a connecting rod is provided at the bottom of the rotating base, and a bearing is provided on the base. The connecting rod is fixedly connected to the inner ring of the bearing.

[0023] The connecting rod is fixedly connected to the inner ring of the bearing, which greatly improves the stability of the rotating base during rotation. Compared with traditional connection methods, such as simple bushing connections, using bearings can effectively reduce radial and axial wobble during rotation. When checking the flatness of the fixed frame, the movement trajectory of the test piece is more stable, reducing measurement deviations caused by rotational instability.

[0024] Stable rotation ensures that the movement path and measurement angle of the test piece remain consistent throughout each test, resulting in better consistency and repeatability of the test data. When inspecting mass-produced fixture products, operators can more reliably judge product quality based on the test data, reducing misjudgments caused by excessive data fluctuations and improving the reliability and efficiency of the inspection work.

[0025] In a preferred embodiment of this utility model, the edge of the base is provided with a locking groove, and the locking member is slidably disposed in the locking groove; the locking member includes a locking slider and a locking pin, the locking slider is slidably disposed in the locking groove, and a pressing part is provided on one side of the locking slider, the pressing part protruding from the side wall of the locking slider into the placement position;

[0026] The bottom of the locking groove is provided with a locking hole, and the locking pin passes through the locking slider and is detachably connected to the locking hole.

[0027] The locking element is slidably mounted in the mounting slot, allowing for flexible position adjustment. This enables the testing mechanism to adapt to fixtures of different sizes and shapes. In actual production, manufacturers may produce fixtures of various specifications. Traditional testing equipment with fixed locking positions cannot meet diverse needs. This design, however, allows for quick adaptation to new products simply by sliding and fixing the locking slider. For example, previously, changing product specifications might have required replacing the entire testing fixture, which was time-consuming, labor-intensive, and costly. Now, by adjusting the position of the locking element, adaptation can be completed quickly, improving production efficiency and reducing equipment modification costs. The locking element features a detachable structure, with the locking pin passing through the locking slider and connecting to the locking hole, facilitating individual maintenance and replacement of the locking components. When the locking slider or locking pin is worn or damaged, the entire testing mechanism can be replaced directly without disassembling the entire mechanism. This not only shortens equipment repair time and reduces maintenance costs but also facilitates upgrades and modifications to the locking structure.

[0028] In a preferred embodiment of this invention, a plurality of positioning blocks are provided in the placement position, and a positioning groove is provided on the product to be tested, wherein the positioning blocks are adapted to the positioning groove.

[0029] The design of the positioning block and positioning slot, which are compatible, ensures that the product maintains a stable and accurate position during the testing process, effectively reducing testing errors caused by positional deviations. The product can be quickly and accurately positioned in its place using the cooperation of the positioning block and positioning slot, reducing the time spent on product positioning before testing. This improves equipment utilization and increases the company's production efficiency.

[0030] The second objective of this utility model is to provide a fixed frame production system, including the flatness detection mechanism described above.

[0031] The beneficial effects of this utility model are as follows:

[0032] This utility model provides a flatness testing mechanism. The mechanism has a base with a product placement area and a locking component for securing the product to be tested, located on one side of the placement area. A testing component, including a testing element, is also provided on the base, positioned above and facing the placement area and pivotally connected to the base. In use, the product to be tested is placed on the placement area, and the locking component securely fixes the product. The testing element then checks a specific location on the product from its initial position. The testing element rotates around the pivot point on the base, continuously checking the flatness data at different locations. If the data exceeds a preset tolerance range, the operator marks the product as unqualified. This testing mechanism allows for rapid and comprehensive testing of the product in the placement area through the rotation of the testing element, improving testing efficiency. Furthermore, the testing element can rotate 360 ​​degrees on the base, allowing for comprehensive testing of all locations on the product, ensuring no potential flatness issues are missed, further improving testing accuracy.

[0033] This application also provides a fixture production system including the above-mentioned flatness testing mechanism. After the fixture is produced, the system uses the above-mentioned testing mechanism to test the fixture. This not only enables the fixture to be tested quickly, but also helps to control the quality of the fixture and prevent unqualified products from entering the market. Attached Figure Description

Product to be tested; Detailed Implementation

[0042] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0043] In the transmission system of an air conditioner, the upper and lower fixed frames serve as the basic framework of the transmission system. Through their own guide rail grooves, they provide precise guidance and support for moving parts (such as gears, connecting rods, etc.), ensuring the smoothness and coaxiality of the transmission process. The flatness of the guide rail groove of the fixed frame directly affects the fitting accuracy of the moving parts. In particular, small deformations or dimensional deviations of the guide rail groove may lead to increased transmission clearance, causing noise, vibration, or even functional failure. Therefore, it is necessary to test the flatness of the guide rail groove on the fixed frame during the production process. Existing methods for testing the flatness of the guide rail groove include: (1) indirectly inferring the internal flatness by measuring the deformation of the outer periphery of the guide rail groove with a flat feeler gauge. This method has the problem of secondary tolerance error accumulation, and the flat feeler gauge cannot be perfectly matched with the surface of the guide rail groove, resulting in insufficient measurement accuracy. (2) measuring the dimensions at both ends of the guide rail groove with calipers. However, this method can only determine the deformation at both ends of the guide rail groove, but cannot effectively detect the middle area of ​​the guide rail groove.

[0044] Based on this, this application provides a flatness testing mechanism.

[0045] Example 1

[0046] like Figures 1-6 As shown, a flatness testing mechanism includes a base 1, on which a product placement position 11 is provided;

[0047] The base 1 is provided with a locking member 3 for fixing the product 100 to be tested, and the locking member 3 is located on one side of the placement position 11;

[0048] The base 1 is also provided with a detection component 2, which includes a detection element 23. The detection element 23 is disposed above the placement position 11 and facing the placement position 11, and the detection element 23 is pivotally connected to the base 1.

[0049] Specifically, the placement position 11 of this application is specially designed according to the shape and size of the product to be tested, ensuring that the product can be placed stably. The locking member 3 located on one side of the placement position 11 is an adjustable clamp-type locking member 3, which is threadedly connected to the base 1 and can be flexibly adjusted according to the actual size of the product. The testing component 2 includes a testing member 23, a rotating shaft connected to the testing member 23, and a bearing seat for supporting the rotating shaft. In practical applications, the rotating shaft can be driven manually or electrically.

[0050] During operation, the testing mechanism places the product to be tested on the placement position 11 and secures it firmly by adjusting the locking component 3. Then, the testing component 23, initially positioned, inspects a specific location on the product. The testing component 23 rotates around a pivot point on the base 1, continuously monitoring the flatness of different locations on the product during rotation. If the data exceeds a preset tolerance range, the operator marks the product as unqualified. This testing mechanism, through the rotation of the testing component 23, allows for rapid and comprehensive inspection of the products in placement position 11, improving testing efficiency. It can quickly complete testing tasks, matching the production rhythm and preventing delays in the testing process from affecting the overall production progress, thus improving factory production efficiency and capacity. Furthermore, the testing component 23 can rotate 360 ​​degrees on the base 1, comprehensively inspecting all locations on the product to ensure no potential flatness issues are overlooked, further improving testing accuracy. In contrast, manual inspection is prone to errors due to differences in operator technique and experience. For example, when using measuring tools to inspect flatness, problems such as inaccurate measurement angles and reading errors may occur. However, this inspection mechanism uses a high-precision displacement sensor as the inspection element 23, and the rotation of the inspection element 23 and data acquisition are precisely controlled by a controller, which can avoid errors caused by manual inspection and improve the accuracy of the inspection.

[0051] Example 2

[0052] like Figures 1-6 As shown, this embodiment is a further improvement on embodiment 1.

[0053] In this embodiment, a rotating base 21 is provided on the base 1, the rotating base 21 is pivotally connected to the base 1, and the detection element 23 is connected to the rotating base 21 through a swing rod 22.

[0054] In this embodiment, the top of the rotating base 21 is provided with a mounting groove 231, the swing rod 22 has a first end and a second end opposite to each other, the first end of the swing rod 22 is hinged to the mounting groove 231 by a pin, and the detection element 23 is disposed at the second end of the swing rod 22;

[0055] A pressure block 233232 is provided at the top of the mounting groove 231, and the pressure block 233232 is located above the swing arm 22.

[0056] Specifically, the base 1 is made of high-strength aluminum alloy and is machined by milling, drilling and other processes to create the shaft hole and mounting structure that pivotally connects with the rotating base 21; the rotating base 21 is made of stainless steel and is precisely machined by a CNC machining center to create the mounting groove 231, bushing mounting hole and other structures; the rocker arm 22 is made of lightweight and high-strength carbon fiber material, and is formed by mold and surface treated to ensure its strength and precision.

[0057] First, the rotating base 21 is mounted on the base 1 via a pivot, ensuring smooth rotation and that the clearance meets design requirements. Then, within the mounting groove 231 of the rotating base 21, the first end of the swing arm 22 is hinged to the mounting groove 231 via a pin, adjusting the range of motion of the swing arm 22 to allow it to swing flexibly. Next, the testing piece 23 is mounted on the second end of the swing arm 22 and secured firmly via a threaded connection or a special clamp 25. Finally, a pressure block 233232 is installed on the top of the mounting groove 231, connected to the rotating base 21 via bolts. The position of the pressure block 233232 is adjusted to provide appropriate pressure on the swing arm 22, preventing it from wobbling during testing without affecting its normal swing.

[0058] During use, the product to be tested 100 is placed in the designated position on the base 1 and fixed in place; the rotating base 21 is rotated manually or by a drive device (such as a motor driving a gear and rack mechanism), and the rotating base 21 drives the swing arm 22 and the testing element 23 to rotate around the product; during the rotation, the contact of the testing element 23 (dial indicator) contacts the product surface, the swing arm 22 swings according to the change in the flatness of the product surface, and the dial indicator measures and displays the flatness data of different positions of the product in real time; the operator judges whether the product meets the flatness standard by observing the data of the dial indicator. If it exceeds the standard range, the product is marked or recorded.

[0059] The swing arm 22 is hinged to the rotating base 21 via a pin, allowing the swing arm 22 to swing freely within a certain angle range. This design can accommodate products 100 of different shapes and sizes to be inspected. When inspecting different types of fixtures, the swing arm 22 can automatically adjust its angle according to the undulations and shape changes of the product surface, ensuring that the inspection piece 23 can always maintain good contact with the product surface, achieving accurate inspection without the need for frequent changes in inspection equipment or adjustments to the inspection position, thus improving the versatility and flexibility of the inspection.

[0060] Example 3

[0061] like Figures 1-6As shown, this embodiment is a further improvement on embodiment 2.

[0062] In this embodiment, the detection element 23 is a displacement sensor, and the bottom of the displacement sensor is provided with a contact, which is positioned towards the placement position 11.

[0063] More preferably, the displacement sensor is any one of a mechanical dial indicator, an electronic displacement sensor, or a laser rangefinder.

[0064] Specifically, when the displacement sensor is a mechanical dial indicator, the mechanical dial indicator is installed at the second end of the lever 22 and firmly fixed with a dedicated mounting clamp 25, ensuring that the measuring rod of the dial indicator is perpendicular to the lever 22 and that the contact point is accurately facing the product in the placement position 11. After installation, debugging is performed. First, the dial indicator pointer is zeroed, and then the rotating base 21 is manually rotated to make the lever 22 move the dial indicator contact point along the product surface to simulate the detection path. The rotation of the pointer is observed to check for any jamming or abnormal jumping. If any problems are found, the installation position of the dial indicator is adjusted in time or the moving parts of the lever 22 are checked for interference.

[0065] Mechanical dial indicators can achieve an accuracy of 0.01mm, which is significantly more precise than traditional simple measuring tools (such as ordinary rulers, which typically have an accuracy of 1mm) in measuring the flatness of the fixture. In fixture production, even minute flatness deviations can affect subsequent assembly accuracy and product performance. Using mechanical dial indicators for inspection can control flatness deviations within a very small range, ensuring that the fixture quality meets high-precision requirements and improving the overall product quality.

[0066] If a laser rangefinder is chosen as the displacement sensor, it offers the advantage of non-contact measurement. For fixture products with easily scratched surfaces or those sensitive to contact, the laser rangefinder can perform measurements without touching the product, avoiding damage to the surface caused by contact measurement. Furthermore, the laser rangefinder has a large measurement range, enabling quick and accurate measurement of the flatness of even large fixture products, significantly expanding the applicability of testing institutions.

[0067] When using electronic displacement sensors, they can be directly connected to a data acquisition system to achieve real-time data acquisition and transmission. During the inspection process, the acquired data can be quickly transmitted to a computer or controller, where specialized data analysis software can be used for real-time analysis and processing. For example, two-dimensional or three-dimensional images of product flatness can be generated, visually displaying the distribution of surface flatness, facilitating operators to quickly identify product quality issues, and providing more comprehensive data support for optimizing production processes.

[0068] Example 4

[0069] like Figures 1-6 As shown, this embodiment is a further improvement on embodiment 1.

[0070] In this embodiment, a fixing block 24 is provided at the second end of the swing arm 22, and a clamp 25 is detachably provided on the fixing block 24, and the detection element 23 is clamped on the clamp 25.

[0071] In practical applications, during the assembly of the detection mechanism, the fixing block 24 is first installed at the second end of the swing arm 22 using bolts to ensure a secure connection between the fixing block 24 and the swing arm 22. After connection, the mounting plane of the fixing block 24 is perpendicular to the swing arm 22, ensuring the perpendicularity of the detection component 23 after installation. After installation, a suitable clamp 25 is selected based on the size and shape of the selected detection component 23 (such as a mechanical dial indicator, electronic displacement sensor, or laser rangefinder).

[0072] During the production of the mounting bracket, as product models are updated or quality standards are raised, it may be necessary to replace the inspection components 23 with different precision or types. The detachable clamp design 25 allows for quick replacement of the inspection components 23. For example, when more precise testing of a high-precision mounting bracket is required, the original mechanical dial indicator can be replaced with a more accurate electronic displacement sensor without requiring a large-scale modification of the entire testing mechanism, greatly improving the versatility of the testing equipment and reducing equipment upgrade costs. This application can also design dedicated clamps 25 for different inspection components 23, which can tightly fit the inspection component 23 and provide a stable installation environment.

[0073] Example 5

[0074] like Figures 1-6 As shown, this embodiment is a further improvement on embodiment 1.

[0075] In this embodiment, a connecting rod is provided at the bottom of the rotating base 21, and a bearing is provided on the base 1. The connecting rod is fixedly connected to the inner ring of the bearing.

[0076] Before assembly, the connecting rod at the bottom of the rotating base 21 and the bearing on the base 1 are cleaned to remove surface oil, impurities, etc., ensuring the tightness and stability of the connection. At the same time, the dimensional accuracy of the connecting rod is checked to ensure that its fit tolerance with the inner ring of the bearing is within a reasonable range.

[0077] After connecting the rotating base 21 to the base 1, the entire testing mechanism is debugged. The testing component 23 is installed on the swing arm 22, which is then connected to the rotating base 21. The rotating base 21 is then manually rotated to observe whether the movement trajectory of the testing component 23 is normal and whether there is any jamming or shaking. If any problems are found, the issue should be promptly investigated to determine if it is a problem with the connection between the connecting rod and the bearing, or interference from other components, and appropriate adjustments should be made.

[0078] The connecting rod is fixedly connected to the inner ring of the bearing, which greatly improves the stability of the rotating base 21 during rotation. Compared with traditional connection methods, such as simple bushing connections, the use of bearings can effectively reduce radial and axial wobble during rotation. When checking the flatness of the fixed frame, the movement trajectory of the measuring element 23 is more stable, reducing measurement deviations caused by rotational instability.

[0079] Stable rotation ensures that the movement path and measurement angle of the inspection piece 23 are basically consistent during each inspection, thus providing better consistency and repeatability of the inspection data. When inspecting mass-produced fixture products, operators can more reliably judge product quality based on the inspection data, reducing misjudgments caused by excessive data fluctuations and improving the reliability and efficiency of the inspection work.

[0080] Example 6

[0081] like Figures 1-6 As shown, this embodiment is a further improvement on embodiment 1.

[0082] In this embodiment, the edge of the base 1 is provided with a locking groove 13, and the locking member 3 is slidably disposed in the locking groove 13; the locking member 3 includes a locking slider 31 and a locking pin 32, the locking slider 31 is slidably disposed in the locking groove 13, and a pressing part 311 is provided on one side of the locking slider 31, the pressing part 311 protruding from the side wall of the locking slider 31 into the placement position 11;

[0083] The bottom of the locking groove 13 is provided with a locking hole, and the locking pin 32 passes through the locking slider 31 and is detachably connected to the locking hole.

[0084] The locking component 3 is slidably mounted in the mounting slot 231, allowing for flexible position adjustment. This enables the testing mechanism to adapt to fixtures of different sizes and shapes. In actual production, manufacturers may produce fixtures of various specifications. Traditional testing equipment with fixed locking positions cannot meet diverse needs. This design, however, allows for quick adaptation to new products simply by sliding and fixing the locking slider 31. For example, previously, changing product specifications might have required replacing the entire testing fixture, which was time-consuming, labor-intensive, and costly. Now, by adjusting the position of the locking component 3, adaptation can be completed quickly, improving production efficiency and reducing equipment modification costs. The locking component 3 features a detachable structure, with the locking pin 32 passing through the locking slider 31 and connecting to the locking hole, facilitating individual maintenance and replacement of the locking components. When the locking slider 31 or locking pin 32 becomes worn or damaged, the entire testing mechanism can be replaced directly without disassembling the entire mechanism. This not only shortens equipment repair time and reduces maintenance costs but also facilitates upgrades and modifications to the locking structure.

[0085] More preferably, in this embodiment, the placement position 11 is provided with a plurality of positioning blocks 12, and the product to be tested 100 is provided with a positioning groove, and the positioning blocks 12 are adapted to the positioning groove.

[0086] The design of the positioning block 12, which is adapted to the positioning groove, enables the product to maintain a stable and accurate position during the inspection process, effectively reducing inspection errors caused by positional deviations. Through the cooperation of the positioning block 12 and the positioning groove, the product can be quickly and accurately positioned on the placement position 11, reducing the time spent on product positioning before inspection. This improves equipment utilization and increases the company's production efficiency.

[0087] Example 7

[0088] like Figures 1-6 As shown, this embodiment provides a fixed frame production system, including the flatness detection mechanism described above.

[0089] The production process of the mounting bracket is as follows:

[0090] Highly crystalline engineering plastic granules used to produce the fixing frame are conveyed to the hopper of the injection molding equipment through an automatic feeding system.

[0091] The injection molding machine heats and melts plastic granules according to preset process parameters, then injects them into the mold cavity. After processes such as pressure holding and cooling, the product blank is formed into a fixed frame. The injection molding machine is equipped with a mold temperature control system and a pressure monitoring system to monitor the production process in real time and ensure stable product molding quality.

[0092] The formed fixture product is transported by a robotic arm or manually to the base 1, placement position 11, of the flatness inspection mechanism. The product is quickly and accurately positioned by the cooperation of the positioning block 12 and the product positioning groove. After the locking component 3 securely fixes the product, the inspection component 2 begins to operate. The rotating base 21 drives the inspection component 23 (such as a displacement sensor) to rotate around the product, performing a comprehensive inspection of the flatness of the fixture and the flatness of the guide rail groove. The inspection data is transmitted to the control system in real time, and the control system determines whether the product is qualified according to preset acceptance criteria.

[0093] Products that fail inspection are moved to the defective product processing area by manual labor or robotic arms. Defective products are then categorized and processed according to the specific circumstances of the defect. Products with only minor flatness deviations can be repaired through grinding or correction; severely defective products are scrapped, dismantled, and the raw materials recycled.

[0094] Products that pass inspection are transported to the finished product packaging area via a conveyor line. In the packaging area, the products are cleaned and treated for rust prevention, then packaged according to the prescribed specifications, ready for warehousing or shipment.

[0095] This application effectively controls product quality by introducing a high-precision flatness testing agency to conduct comprehensive testing on the mounting bracket products. This reduces assembly quality issues and after-sales complaints caused by substandard product flatness, contributing to improved brand image and market competitiveness. Effective handling of defective products, recycling of raw materials, and optimization of production processes further reduce scrap rates and material waste.

[0096] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0097] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0098] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
