Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and more specifically, to a grinding wheel wear detection device. Background Technology

[0002] In the field of precision machining of ceramic materials, the grinding wheel, as a core grinding tool, directly determines the machining quality and efficiency based on its wear condition. Due to their high hardness and brittleness, ceramic materials easily generate a large amount of fine particles and powdery waste during grinding. Under the combined effects of grinding force and heat, these waste chips quickly fill and clog the chip-holding space between the abrasive grains of the grinding wheel. As the clogging intensifies, the abrasive grains on the grinding wheel surface gradually lose their cutting ability, leading to a sharp increase in grinding force and a surge in machining temperature. This results in quality defects such as scratches and cracks on the workpiece surface, and may even cause safety accidents such as grinding wheel breakage. For example, in the machining of precision ceramic bearing rings and electronic ceramic substrates, clogging wear can reduce machining efficiency by more than 30%, increase the scrap rate by 20%, and significantly increase production costs. Currently, the detection of grinding wheel clogging wear mostly relies on manual observation or offline sampling. Manual observation depends on the operator's experience, making it difficult to quantify the degree of clogging, and is greatly affected by subjective factors. Therefore, we propose a grinding wheel wear detection device. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a grinding wheel wear detection device to solve the technical problem that current wear detection methods cannot provide a direct observation of the degree of wear and blockage.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a grinding wheel wear detection device, including a detection cylinder, the detection cylinder being a conical structure with a diameter gradually increasing from top to bottom, an outer connecting frame being provided above the detection cylinder, a drive motor being installed on the top of the outer connecting frame, the drive end of the drive motor being connected to the top of the detection cylinder, a plurality of connecting rods being provided in the lower half of the detection cylinder, a blockage removal structure being connected to the bottom of the connecting rods, the blockage removal structure including a plurality of elastic spring connecting rods, a first cleaning ball being provided at the bottom of the spring connecting rods, a plurality of axial cleaning parts being provided on the outer periphery of the first cleaning ball, the axial cleaning parts reciprocating in the axial direction when cooperating with the spring connecting rods to move up and down, and a blowing structure being provided inside the detection cylinder.

[0005] Preferably, the spring connecting rod has an arc-shaped structure and consists of a force-bearing section, a bending section, and a relay section. The relay section is connected to the first clearing ball, the bending section is made of elastic metal material, and the force-bearing section is fixed to the connecting rod.

[0006] Preferably, the axially mounted clearing component includes a clearing spring, one end of which is connected to the outer periphery of the relay section. The clearing spring has a curved shape extending away from the spring connecting rod, and a second clearing ball is connected to the bottom end of the clearing spring.

[0007] Preferably, the bottom of the second and first cleaning balls is at a lower horizontal height than the bottom of the detection cylinder, and the second and first cleaning balls are adapted to the gap between the particles on the grinding wheel surface.

[0008] Preferably, the blowing structure includes multiple guide plates, which are installed at an inclined angle to the inner wall of the detection cylinder, and the multiple guide plates form a guiding air duct that causes the airflow to move downward along the side wall of the detection cylinder.

[0009] Preferably, the blowing structure further includes a curved opening, which is a spout structure that bends inward toward the inside of the detection cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. In this utility model, the first cleaning ball in the blockage removal structure, under the elastic action of the spring connecting rod, undulates with the uneven surface of the grinding wheel, effectively cleaning ceramic waste between the abrasive grains of the grinding wheel; combined with the axial cleaning component, the second cleaning ball moves back and forth along the axis to scrape away waste from the gaps, significantly improving cleaning efficiency. The cleaned waste is left in the detection cylinder, and the operator can intuitively observe the amount and distribution of waste, quickly judge the degree of grinding wheel blockage and wear, and provide a quantitative basis for subsequent adjustments. This solves the problems of strong subjectivity and difficulty in quantification in traditional manual detection, and solves the problem that existing wear detection cannot intuitively observe the degree of blockage and wear.

[0012] 2. This utility model also uses an inclined guide plate and curved opening design in the blow-coagulation structure to form an inward airflow channel when the detection cylinder rotates, which restricts the removed waste debris inside the detection cylinder, preventing the waste debris from overflowing and interfering with the detection results, and ensuring the accuracy of wear detection; at the same time, it prevents waste debris from scattering in the processing environment, reducing environmental pollution and equipment maintenance costs, and further solves the problem that existing wear detection cannot provide a direct observation of the degree of clogging wear.

[0013] 3. This utility model also uses the conical structure of the detection cylinder and the bow-shaped design of the spring connecting rod to enable the cleaning component to closely fit the complex contour of the grinding wheel surface, adapting to the testing needs of grinding wheels of different models and wear levels; the flexible material bending section ensures that the cleaning component can deform flexibly during the cleaning process, effectively removing waste chips while avoiding secondary damage to the grinding wheel surface, ensuring the versatility and reliability of the testing device.

[0014] 4. This utility model also uses a drive motor to automatically rotate the detection cylinder, realizing automated operation of waste cleaning and wear detection without frequent manual intervention. Compared with offline sampling inspection, it can significantly reduce inspection time and avoid the reduction in processing efficiency caused by inspection interruption. It is especially suitable for scenarios with high requirements for processing continuity, such as precision ceramic bearing rings and electronic ceramic substrates, thereby reducing scrap rate and production costs.

[0020] like Figures 1 to 4 As shown, the present invention relates to a grinding wheel wear detection device, including a detection cylinder 1, which is a conical structure with a diameter that gradually increases from top to bottom. An outer connecting frame 2 is provided on the top of the detection cylinder 1. The outer connecting frame 2 is fixed to the outside to determine the position of the device. A drive motor 3 is installed on the top of the outer connecting frame 2. The drive end of the drive motor 3 is connected to the top of the detection cylinder 1. A plurality of connecting rods 4 are provided in the lower half of the detection cylinder 1. A blockage removal structure 5 is connected to the bottom of the connecting rods 4. The blockage removal structure 5 includes a plurality of elastic spring connecting rods 51. A first cleaning ball 502 is provided at the bottom of the spring connecting rods 51.

[0021] The inside of the detection cylinder 1 is also provided with a blowing and cohesive structure 6, which includes multiple guide plates 601. The guide plates 601 are installed at an inclined angle to the inner wall of the detection cylinder 1. The multiple guide plates 601 form a guiding air duct that causes the airflow to move down along the side wall of the detection cylinder 1. The blowing and cohesive structure 6 also includes a curved opening 602, which is connected to the bottom end of the detection cylinder 1. The curved opening 602 is a spout structure that bends inward toward the inside of the detection cylinder 1.

[0022] Working principle: In use, the grinding wheel is placed at the bottom of the detection cylinder 1, and the surface of the grinding wheel pushes the first cleaning ball 502. Then, the drive motor 3 is controlled by the external control structure to drive the detection cylinder 1 to rotate, causing the first cleaning ball 502 to rotate. During the rotation, due to the uneven surface of the grinding wheel and the elasticity of the spring connecting rod 51, the first cleaning ball 502 can follow the up and down movement to clean the ceramic waste between the uneven surfaces of the grinding wheel. At the same time, the rotation of the detection cylinder 1 drives multiple guide plates 601 to rotate at high speed. When the detection cylinder 1 rotates, the airflow impacts the guide plates 601 and changes direction under the action of the guide plates 601, flowing downward along the inclined direction. With the curved opening 602, an inward blowing airflow obstruction is formed, preventing the cleaned ceramic waste from leaving the internal area of ​​the detection cylinder 1. After cleaning, the degree of blockage and wear can be directly observed by observing the collected ceramic waste, which is convenient for subsequent adjustments.

[0023] To improve the efficiency of the cleaning process, multiple spring links 51 form a circular structure. The spring link 51 has an arc-shaped structure and consists of a force-bearing section 511, a bending section 512, and a relay section 513. The relay section 513 is connected to the first clearing ball 502. The bending section 512 is made of elastic metal material. The force-bearing section 511 is fixed to the connecting rod 4.

[0024] The outer periphery of the first cleaning ball 502 is provided with multiple axial cleaning components 53. When the axial cleaning component 53 moves up and down in conjunction with the spring connecting rod 51, it moves back and forth in the axial direction. The axial cleaning component 53 includes a cleaning spring piece 531. One end of the cleaning spring piece 531 is connected to the outer periphery of the relay section 513. The cleaning spring piece 531 is a curved shape extending away from the spring connecting rod 51. The bottom end of the cleaning spring piece 531 is connected to a second cleaning ball 532. The bottom horizontal height of the second cleaning ball 532 and the first cleaning ball 502 is lower than the bottom horizontal height of the detection cylinder 1. The second cleaning ball 532 and the first cleaning ball 502 are adapted to the gap between the particles on the grinding wheel surface.

[0025] Working principle: When the spring connecting rod 51 moves up and down elastically, it will simultaneously press the cleaning spring 531 to bend. When bending, the second cleaning ball 532 can reciprocate in the axial direction of the first cleaning ball 502. During its reciprocating movement, it will further scrape the gap between the concave and convex parts of the grinding wheel and scrape out the ceramic waste in the gap. The design of multiple second cleaning balls 532 greatly improves the cleaning efficiency.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
