Description

Technical Field

[0001] This utility model relates to the field of roller inspection technology, and more specifically to a silicon carbide roller inspection device. Background Technology

[0002] After sintering and secondary processing, silicon carbide rollers are sent to the quality control or inspection workshop for pre-shipment testing. The main tests include straightness and compressive load capacity, and they are categorized according to different grades. Based on experience using lithium battery material kilns, different grades of rollers have corresponding testing methods for straightness and permissible error values. Roller manufacturers compare the actual measured data with the theoretical values ​​calculated by the customer, and then manually select and classify the rollers. The straightness error value of the rollers is generally measured and labeled as a percentage of the roller length. The diameter and length of the rollers directly affect the straightness result. The industry-standard testing method involves placing each roller individually on a horizontal workbench and using a dial indicator for measurement. For example, Chinese Patent Publication No. CN222460617 U discloses a straightness testing device, which includes a base plate, a measuring component, a supporting component, and a positioning component. The supporting component is mounted on the base plate, and the product to be tested is placed on the supporting component. The measuring component is mounted on the supporting component and positioned above the product to be tested. The positioning component is mounted on the supporting component and abuts against both ends of the product to be tested. The positioning component is used to adjust and fix the position of the product to be tested, and the measuring component detects the straightness of the product to be tested. This straightness testing device utilizes the supporting component to support the product to be tested, allowing the product to be rotated and changing the surface to be measured for straightness measurement. Therefore, the measuring component can detect the straightness of all four sides of the product to be tested. During the rotation of the product to be tested, the positioning component fixes the product, preventing instability from affecting the straightness test results and improving the accuracy of the test results. However, a drawback is that it can only test different wall surfaces at one location on the product, resulting in inaccurate results. Therefore, further structural improvements are necessary. Summary of the Invention

[0003] The purpose of this invention is to provide a stable, reliable, easy-to-operate silicon carbide roller detection device that can improve detection accuracy and overcome the shortcomings of existing technologies.

[0004] This utility model achieves the above-mentioned objective by adopting the following technical solution: a silicon carbide roller inspection device, characterized in that it includes an inspection platform, a front roller support assembly, and a rear roller support assembly, with the silicon carbide roller supported on the front roller support assembly and the rear roller support assembly, and multiple dial indicators are sequentially arranged between the front roller support assembly and the rear roller support assembly. By changing the contact point between the dial indicator and the silicon carbide roller, the straightness of the roller is judged by the jump of the dial indicator.

[0005] As a further explanation of the above scheme, a dial indicator bracket is provided on the testing table, the dial indicator is fixed on the dial indicator bracket and suspended above the silicon carbide roller; the suspension method facilitates the adjustment of the contact position between the dial indicator and the roller.

[0006] Furthermore, the dial indicator support includes a support base, a vertical rod, a swing adjustment rod, and a locking knob. The vertical rod is fixed to the support base, and a positioning sleeve is provided at the top of the vertical rod. A rotating disk is provided at the end of the swing adjustment rod, and the swing adjustment rod is fixed to the rotating disk. The locking knob is provided with a screw that passes through the positioning sleeve and is connected and fixed to the rotating disk. By rotating the rotating disk, the angle of the swing adjustment rod can be adjusted, thereby changing the position of the dial indicator. After adjustment, it is fixed with the locking knob. The operation is flexible and convenient and can meet the needs of different testing points.

[0007] Furthermore, the front roller support assembly includes a front roller support and a front roller group disposed on the front roller support. The front roller group includes two corresponding front rollers, and the silicon carbide roller is supported between the two front rollers. The two corresponding front rollers can stably support one end of the roller, ensuring that the roller is not easily shaken during the detection process.

[0008] Furthermore, the rear roller support assembly includes a rear roller support and a rear roller group disposed on the rear roller support. The rear roller group includes two corresponding rear rollers, and the silicon carbide roller is supported between the two rear rollers. Similar to the front roller support assembly, the rear roller support assembly can stably support the other end of the roller, ensuring that the roller as a whole remains stable during testing.

[0009] Furthermore, the front roller support assembly and / or the rear roller support assembly are connected to a motor drive device, which drives the rollers to rotate electrically, thereby causing the silicon carbide roller to rotate 360°. The electric drive method can realize the automatic rotation of the roller without manual rotation, saving manpower, while ensuring the uniformity of rotation and improving the accuracy of detection.

[0010] Furthermore, dial indicators are installed at both ends and the middle of the silicon carbide roller to detect runout values ​​at these locations. These runout values ​​are collected simultaneously. By comparing and converting the detected runout data, the average straightness value is calculated. Rollers with runout values ​​within the error range (defined as being within the acceptable range) are marked and divided again, then packed separately for final shipment. The use of dial indicators at multiple locations allows for comprehensive collection of straightness data from different parts of the roller. The average straightness value obtained through data comparison and conversion is more accurate, facilitating precise classification of the rollers.

[0011] The beneficial effects that this utility model can achieve by adopting the above-mentioned technical solution are:

[0012] 1. This utility model employs a testing platform with a front roller support assembly and a rear roller support assembly, each containing bearings. The two ends of the roller are then supported on top and rotated 360° using a motor. Multiple dial indicators are sequentially installed at both ends and the middle of the roller, between the front and rear roller support assemblies. By changing the contact point between the dial indicators and the silicon carbide roller, and by repeatedly switching the test points, the straightness grade of the roller is comprehensively evaluated using the dial indicator fluctuations, ensuring the accuracy of the measurement data.

[0013] 2. The adjustable structure of the dial indicator bracket allows for flexible adjustment of the dial indicator's position and height, adapting to the inspection of silicon carbide rollers of different specifications. Different grades of rollers are classified in different ways to ensure the accuracy of measurement data, improve inspection efficiency and precision, and meet the stringent requirements for the factory inspection of silicon carbide rollers.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0023] like Figures 1-2 As shown, this utility model is a silicon carbide roller testing device, including a testing platform 1, a front roller support assembly 2, and a rear roller support assembly 3. The silicon carbide roller 4 is supported on the front roller support assembly 2 and the rear roller support assembly 3. Multiple dial indicators 5 are sequentially arranged between the front roller support assembly 2 and the rear roller support assembly 3. By changing the contact point between the dial indicator 5 and the silicon carbide roller 4, the straightness of the roller can be judged by the jump of the dial indicator.

[0024] A dial indicator bracket 6 is provided on the testing table 1. The dial indicator 5 is fixed on the dial indicator bracket 6 and suspended above the silicon carbide roller 4. This arrangement ensures that the dial indicator can stably test the roller, and the suspension method facilitates adjustment of the contact position between the dial indicator 5 and the roller. In this embodiment, the dial indicator bracket 6 includes a bracket base 6-1, a vertical rod 6-2, a swing adjustment rod 6-3, and a locking knob 6-4. The vertical rod 6-2 is fixed on the bracket base 6-1, and a positioning sleeve 6-5 is provided on the top of the vertical rod 6-2. A rotating disk 6-6 is provided at the end of the swing adjustment rod 6-3, and the swing adjustment rod 6-3 is fixed on the rotating disk 6-6. The locking knob 6-4 has a screw that passes through the positioning sleeve and is connected and fixed to the rotating disk 6-6.

The operation is flexible and convenient and can meet the needs of different testing points. The upright 6-2 is equipped with a height adjustment scale. The upright is a telescopic structure, including an inner rod 6-21 and an outer rod 6-22. The inner rod is fitted inside the outer rod, and the outer rod is equipped with a fastening bolt 6-23 for securing the inner rod. With the help of the height adjustment scale and the telescopic structure, the height of the dial indicator can be precisely adjusted to accommodate the inspection of silicon carbide rollers of different diameters.

[0025] The front roller support assembly 2 includes a front roller support 2-1 and a front roller assembly 2-2 mounted on the front roller support 2-1. The front roller assembly includes two corresponding front rollers, with a silicon carbide roller supported between the two front rollers. The outer surface of the front rollers is provided with a wear-resistant layer made of ceramic material. Ceramic material has good wear resistance, which can extend the service life of the front rollers and reduce wear on the roller surface.

[0026] The rear roller support assembly 3 includes a rear roller support 3-1 and a rear roller group 3-2 disposed on the rear roller support. The rear roller group includes two corresponding rear rollers, and the silicon carbide roller is supported between the two rear rollers. Similar to the front roller support assembly, the rear roller support assembly can stably support the other end of the roller, ensuring that the roller as a whole remains stable during testing.

[0027] The front roller support assembly 2 is connected to a motor drive unit 7, which electrically drives the rollers to rotate, thereby causing the silicon carbide rollers to rotate 360°. The electric drive enables automatic rotation of the rollers, eliminating the need for manual rotation, saving manpower, and ensuring uniform rotation, thus improving detection accuracy. The motor drive unit 7 includes a drive motor 7-1, a reduction mechanism 7-2, and a transmission assembly 7-3. The drive motor 7-1 is connected to the transmission assembly 7-3 via the reduction mechanism 7-2, and the transmission assembly is connected to the front roller assembly. The reduction mechanism reduces the speed of the drive motor, making the roller rotation speed more suitable for detection requirements; the transmission assembly stably transmits power to the roller assembly. The transmission assembly 7-3 includes a driving gear and a driven gear. The driving gear is connected to the output end of the reduction mechanism, and the driven gear is connected to the roller shaft of the front roller assembly. The driving gear and driven gear mesh. Gear transmission has advantages such as accurate transmission ratio, high efficiency, and compact structure, ensuring the stability of power transmission.

[0028] In this embodiment, dial gauges are installed at both ends and the middle of the silicon carbide roller to detect runout values ​​at these locations. The runout values ​​at different positions are collected simultaneously. By comparing and converting the detected runout data, the average straightness value is calculated. Rollers with runout values ​​within the error range (defined as within the acceptable range) are marked again, divided equally, and then packed separately for final shipment. Using dial gauges at multiple locations allows for comprehensive collection of straightness data from different parts of the roller. The average straightness value obtained through data comparison and conversion is more accurate, facilitating precise classification of the rollers.

[0029] The working principle of this technical solution is as follows: Silicon carbide rollers are placed on the front and rear roller support assemblies. Based on the roller diameter and testing requirements, the height and position of the dial indicator are adjusted using the dial indicator bracket to ensure the dial indicator probe contacts the roller surface. The motor drive is activated, and the motor, through a reduction mechanism and transmission assembly, drives the front roller assembly to rotate, thereby causing the silicon carbide roller to rotate 360°. During rotation, multiple dial indicators collect runout values ​​at both ends and the middle of the roller. By comparing and converting these runout values, the average straightness data is calculated, and the rollers are classified based on the data. Example 2

[0030] In this embodiment, as Figure 3 As shown, the silicon carbide roller is rotated 360 degrees back and forth manually. This dial indicator requires regular calibration, and the measuring head must be replaced periodically to ensure the accuracy of the measurement data. Dial indicators showing signs of damage should be replaced immediately; continued use is not recommended.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
