[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] The low pass rate and efficiency of inner hole machining in ceramic microporous closed-cell tubes result in high production costs, reducing the market competitiveness of enterprises. Currently, the inner hole machining of ceramic microporous closed-cell tubes uses steel wire and polishing paste for honing. However, the steel wire must have an effective taper at one end to perform the honing process. Previously, the taper of the steel wire was etched using nitric acid, which required highly skilled operators and lacked quantifiable data, relying entirely on employee experience. This resulted in inconsistent tapers on each wire, leading to inconsistent data stability and consistency during the honing process. Products failing subsequent quality control testing required second or third rework, resulting in low efficiency, increased costs, and a lack of market competitiveness. Because nitric acid produces fumes that can harm operators, and because it is a hazardous material, it poses safety risks and introduces unpredictable safety factors for employees during operation. With increasingly stringent safety and environmental requirements, these processes cannot be carried out on the production line and must be conducted in separate, safe isolation rooms, causing difficulties in production line turnover.

[0036] In view of this, see Figure 1 The grinding device provided in this embodiment of the present invention includes a grinding wheel 100, a guide wheel 210, a guide plate 300, a drive assembly, and a control assembly. The axis of the grinding wheel 100 is parallel to the axis of the guide wheel 210. The guide plate 300 is located between the grinding wheel 100 and the guide wheel 210, and the length direction of the guide plate 300 is parallel to the axis of the grinding wheel 100. The drive assembly is connected to the side of the guide wheel 210 away from the grinding wheel 100 to drive the guide wheel 210 to move towards or away from the grinding wheel 100. The control assembly is installed on the discharge side of the guide plate 300 and includes a control center and a first sensor 510 and a second sensor 520 spaced apart along the length direction of the guide plate 300. The first sensor 510, the second sensor 520, and the drive assembly are all signal-connected to the control center. The control center controls the operation of the drive assembly based on the information from the first sensor 510 and the second sensor 520.

[0037] Specifically, this grinding device can grind workpieces of various shapes, such as slender cylindrical workpieces, short shafts without a center hole, and sleeve-type workpieces, demonstrating strong adaptability; it also boasts high machining accuracy and a high degree of automation, making it suitable for mass production. Furthermore, the grinding wheel 100 is made of diamond.

[0038] The first sensor 510 and the second sensor 520 are used to receive the position information of the workpiece being ground and transmit the received position information to the control center. The control center controls the opening and closing, running time, and running speed of the drive assembly. The guide plate 300 supports the workpiece being ground, maintains the stability of the workpiece being ground, and prevents the workpiece from shifting or vibrating during the grinding process; the grinding wheel 100 performs the grinding operation on the workpiece being ground; and the guide wheel 210 controls the rotation of the workpiece being ground. When using this grinding device, the workpiece to be ground extends from the feed side of the guide plate 300 between the grinding wheel 100 and the guide wheel 210, and is located on the guide plate 300; when the feed end of the workpiece to be ground is conveyed to the position corresponding to the first sensor 510, the drive assembly drives the guide wheel 210 to move towards the grinding wheel 100 at a certain speed, so that the workpiece to be ground can gradually form a taper; when the feed end of the workpiece to be ground is conveyed to the position corresponding to the second sensor 520, the drive assembly drives the guide wheel 210 to reset; the distance between the first sensor 510 and the second sensor 520 can be adjusted according to actual needs. This grinding device can process tapered steel wires up to 2 meters in length. The efficiency and dimensional accuracy of the steel wires processed by this device are improved, as is the safety of production. This ensures the machining accuracy and roughness of the inner hole of the ceramic microporous closed sleeve, and also improves processing efficiency and stability, reduces production costs, provides customers with lower-priced and higher-quality products, enhances brand awareness, and strengthens core market competitiveness.
