Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to an automatic measuring machine for precision grinding diameter. Background Technology

[0002] In the prior art, roundness refers to the actual shape of a circular element on a part, which is equidistant from its center; that is, the degree of roundness. Diameter refers to the distance between two points on the edge of a planar figure or solid (such as a circle, a conical section, a sphere, or a cube). Many workpieces now require measurement of their diameter and roundness to improve assembly accuracy.

[0003] Existing diameter and roundness measurements are generally performed manually using equipment, which results in poor accuracy and low efficiency. Utility Model Content

[0004] This application provides an automatic precision grinding diameter detection and measuring machine, which solves the problem that conventional roundness and diameter detection in the prior art requires manual operation of the monitoring equipment by workers, resulting in poor detection accuracy and low detection efficiency.

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

[0006] An automatic diameter measuring machine for precision grinding includes a base; a support assembly located at the center of the base for supporting the product; a measuring mechanism for measuring the product; and two drive mechanisms respectively located at both ends of the measuring mechanism: a drive mechanism for rotating the product, including a stepper motor, a drive wheel driven by the stepper motor, and a transmission wheel connected to the drive wheel via a belt, wherein the drive wheel is fixedly connected to a limiting plate, and the limiting plate has a first center coaxial with the drive wheel; and a clamping mechanism for clamping the product, including a clamping cylinder, an ejector rod driven by the clamping cylinder, and a slide table pushed by the ejector rod, wherein the slide table has a second center for abutting the product; the first and second centers cooperate to clamp the product and drive its rotation.

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

[0008] The limiting plate is provided with a number of positioning pins for limiting the product. The positioning pins guide the product to the correct position and prevent misalignment during rotation.

[0009] The base is equipped with an ejector cylinder, which is used to eject the product after the inspection is completed.

[0010] A spring is fitted onto the ejector rod, with both ends of the spring abutting against the end of the ejector rod and the slide table, respectively, to buffer the clamping force.

[0011] The detection mechanism includes an adjusting cylinder fixed on a base and a bracket driven by the adjusting cylinder. A sensor is provided on the top of the bracket. The adjusting cylinder drives the bracket to move so that the sensor moves closer to or away from the product.

[0012] The sensor is provided with a protective cover, which is placed on the outside of the sensor.

[0013] The base is equipped with an air nozzle for blowing and washing the product and a collection tank for collecting impurities.

[0014] The drive wheel is positioned on the base by a bracket.

[0015] The support assembly includes two support columns, which are used to support the product.

[0016] The sensor is a measuring sensor used to detect the diameter and roundness of a product.

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0018] 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.

[0024] This application provides an automatic precision grinding diameter detection and measuring machine, which solves the problem that conventional roundness and diameter detection in the prior art requires manual operation of the monitoring equipment by workers, resulting in poor detection accuracy and low detection efficiency.

[0025] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1As shown, the automatic precision grinding diameter measuring machine of this embodiment includes a base; a support assembly located at the center of the base for supporting the product; a measuring mechanism 4 for measuring the product; and two drive mechanisms 1 respectively located at both ends of the measuring mechanism 4: a drive mechanism 1 for driving the product to rotate, including a stepper motor 11, a drive wheel 12 driven by the stepper motor 11, and a transmission wheel 14 connected to the drive wheel 12 via a belt 13. The drive wheel 12 is fixedly connected to a limiting plate 15, and the limiting plate 15 is provided with a first center 16 coaxial with the drive wheel 12; and a clamping mechanism 2 for clamping the product, including a clamping cylinder 21, an ejector rod 22 driven by the clamping cylinder 21, and a slide 24 pushed by the ejector rod 22. The slide 24 is provided with a second center 25 for abutting the product. The first center 16 and the second center 25 cooperate to clamp the product and drive it to rotate.

[0028] The limiting plate 15 is provided with several positioning pins 17 for limiting the product. The positioning pins 17 guide the product to the correct position and prevent misalignment during rotation.

[0029] An ejector cylinder 5 is installed on the top of the base. The ejector cylinder 5 is used to eject the product after the test is completed.

[0030] A spring 23 is fitted on the ejector rod 22. The two ends of the spring 23 abut against the end of the ejector rod 22 and the slide table 24, respectively, to buffer the clamping force.

[0031] The testing mechanism 4 includes an adjusting cylinder 41 fixed on the base and a bracket 42 driven by the adjusting cylinder 41. A sensor 43 is provided on the top of the bracket 42. The adjusting cylinder 41 drives the bracket 42 to move so that the sensor 43 is closer to or further away from the product.

[0032] The sensor 43 is provided with a protective cover 44, which is fitted over the outside of the sensor 43.

[0033] The base is equipped with an air nozzle 6 for blowing and washing the product and a collection tank 7 for collecting impurities.

[0034] The drive wheel 14 is positioned on the base via the bracket 42.

[0035] The support assembly includes two support columns 3, which are used to support the product.

[0036] Sensor 43 is a measuring sensor used to detect the diameter and roundness of a product.

[0037] By employing a stepper motor 11 to drive the active wheel 12 to rotate the product, and coaxially clamping the first and second centers 16 and 25, 360° inspection without blind spots is achieved. The sensor 43 of the inspection mechanism 4, driven by the adjusting cylinder 41, precisely approaches the product, 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 greatly 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 2 provides flexible clamping force to the second center 25 through the buffering effect of the ejector rod 22 and spring 23, ensuring stable product clamping while preventing product deformation caused by rigid compression. The positioning pin 17 on the limit plate 15 guides the product into precise position, preventing misalignment due to vibration during rotation. Combined with the stable support of the support column 3, this ensures the product maintains coaxiality throughout the inspection process, further guaranteeing the reliability of the measurement data. The air nozzle 6 can blow away impurities from the product surface in real time, and the collection tank 7 collects debris to prevent dust from affecting the detection accuracy of the sensor 43. The protective cover 44 on the outside of the sensor 43 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 adjusting cylinder 41 drives the sensor 43 bracket 42 to move flexibly, which can adapt to the detection needs of products with different diameters. The ejection cylinder 5 automatically ejects the product after detection. With the clamping mechanism 2 buffered by the spring 23, the entire process from product clamping to removal is automated, reducing manual intervention. The combination design of the positioning pin 17 and the support column 3 allows for quick positioning of products of different specifications, reducing the complexity of changeover adjustments.

[0038] First, the robotic arm loads the product onto two support columns 3. The clamping mechanism 2 operates, causing the second tip 25 to press against the product, which, together with the first tip 16, firmly clamps the product. At this point, the positioning pin 17 guides the product to be precisely locked onto the limit plate 15. Next, the detection mechanism 4 operates, and the adjusting cylinder 41 drives the bracket 42 to move forward, bringing the sensor 43 closer to the product until it reaches the detection position. Then, the drive mechanism 1 operates, and the stepper motor 11 causes the limit plate 15 to rotate the product one revolution. The sensor 43 collects and calculates the product data. Finally, the detection mechanism 4 drives the sensor 43 to move backward, the clamping mechanism 2 separates from the product, and the ejection cylinder 5 ejects the product from the limit plate 15. The robotic arm then removes the product.
