Description

Technical Field

[0001] This utility model relates to the field of flatness measurement, and in particular to an automatic flatness measuring machine. Background Technology

[0002] In the existing technology, flatness measurement is the measurement of flatness error in length measurement technology. Many products need to measure the flatness of some surfaces to improve assembly accuracy.

[0003] Existing flatness measurements are generally performed manually, which not only results in poor accuracy but also limits the measurement area. Utility Model Content

[0004] This application provides an automatic flatness measuring machine, which solves the problems of poor detection accuracy and small detection range in conventional flatness detection, which is carried out manually in the prior art.

[0005] The technical solutions adopted in the embodiments of this application are as follows.

[0006] An automatic flatness measuring machine includes a base, a top plate on the base, a mounting plate between the top plate and the base, a lifting cylinder on the top plate for driving the mounting plate to rise and fall, a plurality of detection elements for detecting the flatness of the product on the mounting plate, and a positioning plate slidably disposed on the base for fixing the product and moving it below the mounting plate.

[0007] As a further improvement to the above technical solution:

[0008] The top plate is fixed to the base by several guide rods, which pass through the mounting plate and are used to guide the mounting plate to rise and fall.

[0009] The positioning plate is provided with a handle for easy gripping to move the positioning plate.

[0010] The bottom of the positioning plate is provided with a guide rail, which is used to reduce the friction between the positioning plate and the base and guide the positioning plate to slide.

[0011] The positioning plate is provided with positioning blocks and several positioning pins. The positioning blocks are used to support the parts of the product with larger mass, and the positioning pins are used to support the parts of the product with relatively smaller mass. The positioning blocks and positioning pins cooperate to keep the surface of the product to be tested horizontal.

[0012] The base is provided with a buffer assembly, which includes a buffer cylinder, a spring disposed inside the buffer cylinder, and a top block disposed on the spring. The top block is provided with a rubber buffer pad.

[0013] The base is provided with a positioning block, and the positioning plate is provided with a positioning groove. The positioning block and the positioning groove cooperate to prevent the positioning plate from falling off the guide rail and to ensure that the positioning plate is accurately positioned.

[0014] The testing components include a testing sleeve embedded in the mounting plate and a flatness testing sensor inserted into the testing sleeve. The number and installation position of the testing components can be adjusted according to the shape and size of the surface of the product to be tested.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0016] 1. By employing a stepper motor-driven drive wheel to rotate the product, coupled with coaxial clamping of the first and second centers, 360° inspection without blind spots is achieved. The sensor in the inspection mechanism, driven by an adjusting cylinder, precisely approaches the product, replacing manual handheld operation and avoiding human error or reading inaccuracies, significantly improving the accuracy of diameter and roundness measurements. The automated process drastically reduces the inspection time for a single product, making it particularly suitable for batch inspection scenarios and solving the problem of low efficiency in traditional manual inspection. The clamping mechanism, through the buffering effect of the ejector rod and spring, provides flexible clamping force to the second center, ensuring stable product clamping while preventing deformation caused by rigid compression. Positioning pins on the limit plate guide the product precisely into position, preventing misalignment due to vibration during rotation. Combined with the stable support of the support column, this ensures the product maintains coaxiality throughout the inspection process, further guaranteeing the reliability of measurement data. Air nozzles can blow away impurities from the product surface in real time, and a collection tank collects debris, preventing dust from affecting sensor accuracy. Protective covers on the outside of the sensors prevent damage from accidental collisions, extending the equipment's lifespan. These designs provide a clean and safe environment for high-precision testing, reducing testing deviations caused by environmental factors. The adjustable cylinder drives the sensor bracket to move flexibly, adapting to the testing needs of products with different diameters. The ejector cylinder automatically ejects the product after testing, and, in conjunction with a spring-buffered clamping mechanism, automates the entire process from clamping to removal, reducing manual intervention. The combination of positioning pins and support columns allows for quick positioning of products of different specifications, reducing the complexity of changeover adjustments.

[0028] The base 1 is provided with a buffer assembly 10, which includes a buffer cylinder, a spring disposed inside the buffer cylinder, and a top block disposed on the spring. The top block is provided with a rubber buffer pad.

[0029] The base 1 is provided with a positioning block 8 and the positioning plate 6 is provided with a positioning groove. The positioning block 8 and the positioning groove cooperate to prevent the positioning plate 6 from falling out of the guide rail 9 and to ensure that the positioning plate 6 is accurately positioned.

[0030] The detection component 5 includes a detection sleeve embedded in the mounting plate 4 and a flatness detection sensor inserted into the detection sleeve. The number and installation position of the detection component 5 can be adjusted according to the shape and size of the surface to be detected on the product 13.

[0031] By employing a stepper motor-driven drive wheel to rotate product 13, coupled with coaxial clamping of the first and second centers, 360° inspection of product 13 is achieved without blind spots. The sensor in the inspection mechanism, driven by an adjusting cylinder, precisely approaches product 13, replacing the manual handheld inspection mode and avoiding human error or reading errors, significantly improving the accuracy of diameter and roundness measurements. The automated process drastically reduces the inspection time for a single product 13, making it particularly suitable for batch inspection scenarios and solving the problem of low efficiency in traditional manual inspection. The clamping mechanism, through the buffering effect of the ejector rod and spring, provides flexible clamping force to the second center, ensuring stable clamping of product 13 while preventing deformation caused by rigid compression. The positioning pin 11 on the limit plate guides product 13 into precise position, preventing misalignment due to vibration during rotation.

The air nozzle can blow away impurities from the surface of product 13 in real time, and the collection tank collects debris to prevent dust from affecting the sensor's detection accuracy. The protective cover on the outside of the sensor can prevent damage from accidental collisions and extend the service life of the equipment. These designs provide a clean and safe environment for high-precision detection and reduce detection deviations caused by environmental factors. The adjustable cylinder drives the sensor bracket to move flexibly to adapt to the detection needs of products 13 with different diameters. The ejection cylinder automatically ejects product 13 after detection, and with the spring-buffered clamping mechanism, the entire process of product 13 from clamping to removal is automated, reducing manual intervention. The combination design of the positioning pin 11 and the support column allows for quick positioning of products 13 of different specifications, reducing the complexity of changeover adjustments.

Then, the worker controls the lifting cylinder 3 to work, so that the mounting plate 4 is pressed down and the inspection piece 5 will contact the surface to be inspected. Several inspection pieces 5 perform flatness inspection on the surface to be inspected. Finally, the lifting cylinder 3 moves the mounting plate up, the worker pulls out the positioning plate 6 and takes out the product 13.
