Description

Technical Field

[0001] The utility model belongs to the field of detection technology, and in particular relates to a device for measuring the dimensional accuracy of a flexible rubber product. Background Art

[0002] Rubber is a polymer material with high elasticity. Rubber parts made of rubber as the main material have high elasticity. When performing dimensional inspection on rubber parts, it is difficult to overcome material deformation using traditional measuring tools, making it difficult to obtain accurate dimensional data. In addition, irregular shapes such as curved surfaces on the surface of rubber parts are difficult to measure using traditional measuring tools. Traditional measurement methods are inefficient and difficult to measure during the production process to control the dimensional accuracy of rubber parts, making it impossible to guarantee that rubber parts will be qualified before leaving the factory.

[0003] Therefore, the above problems need to be solved urgently. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the utility model provides a flexible rubber product dimensional accuracy measuring device, which can realize the dimensional measurement of soft irregular rubber parts, ensure measurement accuracy, avoid batch scrapping, improve measurement efficiency and reduce labor costs.

[0005] Technical solution: In order to achieve the above-mentioned purpose, the present invention provides a device for measuring the dimensional accuracy of flexible rubber products, including an image measuring device. The top surface of the image measuring device platform is connected to a measuring fixture, and the measuring fixture is provided with a rubber part to be measured. The image measuring device detects the size of the rubber part to be measured. The measuring fixture includes a base plate, the top surface of the base plate is integrally provided with a boss, and the side walls of the boss are provided with limiting ribs, which are vertically provided on the side walls of the boss. During detection, the limiting ribs extend into the opening provided in the rubber part to be measured, and the limiting ribs limit the rubber part to be measured. The image measuring device is an image measuring instrument. The rubber part to be measured is a thin-walled part made of rubber as the main material. The rubber part has an irregular shape and its soft wings are deformed. It is difficult for traditional measuring tools to measure accurately. The utility model sets the rubber part to be measured on the measuring fixture, and the measuring fixture supports the rubber to be measured from the inside out and from the top to the top, so as to avoid deformation of the rubber to be measured during the measurement process, which affects the measurement accuracy. The opening of the rubber part to be tested engages a retaining rib, which ensures that the rubber part fits along the rib onto the boss. The image measuring device is then used to measure the rubber part's dimensions. If the rubber part fails to fit along the rib onto the boss, the inspector can immediately determine that the rubber part is unqualified. This utility model ensures measurement consistency during rubber part inspection by using the image measuring device after the rubber part is inserted into the boss. This prevents deformation of the rubber part caused by contact during measurement, ensuring measurement accuracy, improving efficiency, and reducing labor costs.

[0006] Furthermore, in the aforementioned flexible rubber product dimensional accuracy measuring device, the limiting ribs include a first limiting rib and a second limiting rib. The first limiting rib and the second limiting rib are disposed on one side of the boss. The bottoms of the first limiting rib and the second limiting rib are both connected to the base plate. The top surface of the first limiting rib is higher than the top surface of the second limiting rib. The first limiting rib and the second limiting rib are disposed corresponding to the opening of the rubber part to be measured. During measurement, the first limiting rib and the second limiting rib are respectively engaged within the opening of the rubber part to be measured, limiting the rubber part to be measured, ensuring that the angle between the rubber part to be measured and the boss is consistent during measurement. The top surfaces of the first limiting rib and the second limiting rib provide support for the rubber part to be measured, fully supporting the inner wall of the rubber part to prevent deformation of the rubber part and affecting the measured dimensional accuracy.

[0007] Furthermore, in the above-mentioned flexible rubber product dimensional accuracy measuring device, the top surfaces of the first limiting rib and the second limiting rib are both inclined surfaces, and the top surfaces of the first limiting rib and the second limiting rib are both inclined downwardly away from the boss.

[0008] Furthermore, in the flexible rubber product dimensional accuracy measuring device, two bosses are provided, and the two bosses are mirror-imaged on the top surface of the base plate. The two mirror-image bosses can simultaneously test two symmetrical rubber parts, thereby improving testing efficiency and adaptability.

[0009] Furthermore, in the above-mentioned flexible rubber product dimensional accuracy measuring device, a notch is provided on the side of the boss away from the first limiting rib, the vertical cross-section of the notch is arc-shaped, and the notch corresponds to the rubber part.

[0010] Furthermore, in the above-mentioned flexible rubber product dimensional accuracy measuring device, the cross section of the end of the boss close to the second limiting rib is arc-shaped.

[0011] Furthermore, in the aforementioned flexible rubber product dimensional accuracy measurement device, the sidewalls of the boss are provided with draft angles, which correspond to the inner sidewalls of the rubber component on the opposite side. After the rubber component is inserted into the boss, the inspector checks the gap between the rubber component and the boss by touch and observation, making a preliminary assessment of the rubber component. If the gap is too large, the component is deemed dimensionally unacceptable.

[0012] Furthermore, in the aforementioned flexible rubber product dimensional accuracy measurement device, the width and shape of the limiting ribs are configured to correspond to the opening of the rubber part being tested. If, during testing, the limiting ribs fail to extend into the opening of the rubber part, the opening can be quickly determined to be unqualified, and production should be halted immediately to prevent further losses.

[0013] As can be seen from the above technical solution, the present invention has the following beneficial effects: The present invention's flexible rubber product dimensional accuracy measuring device inserts a rubber part into a boss along a limiting rib. The gap between the rubber part and the boss is inspected by touch and observation, allowing for a preliminary assessment of the rubber part. If the gap is too large or the part cannot be inserted, the rubber part is deemed unqualified. After the rubber part is inserted into the boss, it is measured using an image measuring device, preventing deformation of the rubber part caused by contact with the measuring tool during measurement. This ensures measurement accuracy, improves measurement efficiency, and reduces labor costs. The limiting ribs are used to quickly determine the opening position and size of the rubber part, improving inspection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1-2The device for measuring the dimensional accuracy of a flexible rubber product shown in the figure includes an image measuring device 1. A measuring fixture 2 is connected to the top surface of the detection platform of the image measuring device 1. The measuring fixture 2 is equipped with a rubber part to be measured. The image measuring device 1 detects the size of the rubber part to be measured. The measuring fixture 2 includes a base plate 21. The top surface of the base plate 21 is integrally provided with a boss 22. The side walls of the boss 22 are provided with limiting ribs 23. The limiting ribs 23 are vertically arranged on the side walls of the boss 22. The limiting ribs 23 include a first limiting rib 231 and a second limiting rib 232. The first limiting rib 231 and the second limiting rib 232 are both connected to the base plate 21 at their bottoms. The top surface of the first limiting rib 231 is higher than the top surface of the second limiting rib 232. The first limiting rib 231 and the second limiting rib 232 are arranged corresponding to the opening of the rubber part to be measured. The top surfaces of the first limiting rib 231 and the second limiting rib 232 are both inclined surfaces, and the top surfaces of the first limiting rib 231 and the second limiting rib 232 are both inclined downward toward the side away from the boss 22. There are two bosses 22, and the two bosses 22 are mirror-imaged on the top surface of the bottom plate 21. The side of the boss 22 away from the first limiting rib 231 is provided with a notch 233, and the vertical cross-section of the notch 233 is arc-shaped, and the notch 233 is provided corresponding to the rubber part. The cross-section of the end of the boss 22 close to the second limiting rib 232 is arc-shaped. The side wall of the boss 22 is provided with a draft angle, and the above-mentioned draft angle is provided corresponding to the inner side wall of the rubber part on the opposite side. The width and shape of the limiting rib 23 are provided corresponding to the opening of the rubber part to be tested. The rubber part to be tested is a bilaterally symmetrical part.

[0019] The rubber parts to be tested are thin-walled parts made of rubber as the main material. The rubber parts are irregular in shape, soft and easy to deform. Traditional measuring tools need to contact the object for measurement, which can easily cause deformation of the rubber parts and make accurate measurement difficult.

[0020] The present invention inserts a bilaterally symmetrical rubber part to be tested onto a mirror-image boss 22. During insertion, the opening of the rubber part is aligned with the first limiting rib 231 and the second limiting rib 232. The opening of the rubber part to be tested is then inserted into the first limiting rib 231 and the second limiting rib 232. The image measuring device 1 is then used to measure the dimensions of the rubber part. If the rubber part cannot be inserted into the boss 22 along the first limiting rib 231 and the second limiting rib 232, the opening dimension of the rubber part is unqualified. If the rubber part cannot be inserted into the boss 22, the main body dimension of the rubber part is unqualified. After the rubber part is inserted into the boss 22, the inspector checks the gap between the rubber part and the boss 22 by touch and observation, making a preliminary assessment of the rubber part. If the gap is too large, the size is unqualified.

[0021] Image measuring device 1 is an image measuring instrument, a high-precision optical measuring device that uses non-contact measurement and boasts high measurement accuracy. It uses a high-resolution CCD color camera to capture object feature points. Multiple feature points are captured by moving the object. During this movement, a precision grating ruler records the distance traveled for each feature point. Measurement and analysis are performed based on the extracted feature point data to obtain the object's dimensional information.
