Description

Technical Field

[0001] This utility model relates to the field of oil tank structure, specifically to a self-lubricating embedded oil tank structure for table saw hardware. Background Technology

[0002] The embedded oil groove structure involves machining specific-shaped grooves at key friction points to achieve continuous lubrication through pre-filling with grease or capillary action. This structure reduces the frequency of external lubrication, lowers frictional losses, and is particularly suitable for dusty environments under high-speed cutting conditions. Its embedded design prevents the oil groove from being exposed, thus preventing debris blockage, while optimizing oil film distribution and improving the wear resistance and operational stability of the table saw's hardware.

[0003] During the use of table saw hardware, traditional structures lack effective constraints on the lubrication area, which easily leads to lubricant overflow. At the same time, due to the lack of a good oil storage structure, it is impossible to store enough lubricant to meet the self-lubrication requirements. Furthermore, the lubricant is difficult to distribute evenly, which cannot guarantee the uniformity of lubrication. In addition, without an effective oil guiding mechanism, it is difficult to continuously and stably guide the lubricant to the parts that need lubrication, resulting in greater friction and wear between the table saw hardware and affecting its service life. Utility Model Content

[0004] The purpose of this utility model is to solve the above defects and provide a self-lubricating embedded oil groove structure for table saw hardware. This structure ensures the continuity and stability of lubrication, thereby effectively reducing friction and wear between table saw hardware and extending its service life. It solves the technical problems of existing technologies, such as easy lubricant overflow, inability to store enough lubricant to meet self-lubrication needs, inability to guarantee lubrication uniformity, and difficulty in continuously and stably guiding lubricant to the parts that need lubrication.

[0005] The objective of this utility model is achieved through the following means:

[0006] A table saw hardware component self-lubricating embedded oil groove structure includes a base, an oil groove outer frame installed on the upper surface of the base, a porous copper-based sintered layer installed on the upper surface of the base, an oil-containing ceramic particle pre-embedded layer evenly distributed on the surface of the porous copper-based sintered layer, oil holes evenly opened on the surface of the oil-containing ceramic particle pre-embedded layer, and capillary oil guiding channels evenly distributed on the surface of the porous copper-based sintered layer.

[0007] Furthermore, the porous copper-based sintered layer has transversely uniformly opened conveying channels on its surface. The opening positions of the conveying channels are adapted to the capillary oil guiding channels, and the conveying channels all penetrate the surface of the capillary oil guiding channels. After the porous copper-based sintered layer is prepared, a precision machining process is used to open the conveying channels transversely uniformly on its surface according to a predetermined spacing and direction. During the opening process, the machining accuracy is strictly controlled to ensure that each conveying channel can accurately penetrate the surface of the capillary oil guiding channels that are uniformly arranged on the surface of the porous copper-based sintered layer in advance. This ensures that the lubricating oil can smoothly enter through the conveying channels and be reasonably guided through the capillary oil guiding channels.

[0008] Furthermore, the surface of the oil-containing ceramic particle pre-embedded layer is uniformly provided with oil guide grooves. The opening position of the oil guide grooves is adapted to the capillary oil guide channel, and the capillary oil guide channel communicates with the inner cavity of the capillary oil guide channel. After the oil-containing ceramic particle pre-embedded layer is laid on the porous copper-based sintered layer, high-precision micro-machining technology is used to uniformly open oil guide grooves on the surface of the oil-containing ceramic particle pre-embedded layer according to specific spacing and rules. During the opening process, the direction and depth of the oil guide grooves are precisely controlled to ensure that each oil guide groove can accurately connect with the inner cavity of the capillary oil guide channel that is uniformly laid on the surface of the porous copper-based sintered layer, thereby establishing a smooth lubricating oil flow path.

[0009] Furthermore, mounting grooves are provided on the upper surface of the porous copper-based sintered layer and at corresponding positions of the oil-impregnated ceramic particle pre-embedded layer. The oil-impregnated ceramic particle pre-embedded layers are all installed inside the mounting grooves. After the preparation of the porous copper-based sintered layer is completed and the specifications and dimensions of the oil-impregnated ceramic particle pre-embedded layer are determined, mounting grooves are uniformly opened on the upper surface of the porous copper-based sintered layer and at corresponding positions of the oil-impregnated ceramic particle pre-embedded layer according to the shape and size of the oil-impregnated ceramic particle pre-embedded layer, according to the precise dimensions and depth. Then, the oil-impregnated ceramic particle pre-embedded layers are accurately placed one by one into the mounting grooves, and appropriate pressure is applied to ensure that the oil-impregnated ceramic particle pre-embedded layer is firmly installed and tightly attached to the mounting groove.

[0010] Furthermore, both the oil-impregnated ceramic particle pre-embedded layer and the installation groove are designed in a rhombus shape. The surface of the oil-impregnated ceramic particle pre-embedded layer is provided with raised ceramic particles. After the preliminary processing of the porous copper-based sintered layer is completed, the size, angle and spacing of the rhombus installation groove are planned according to the overall design requirements. Using equipment with high-precision processing capabilities, the rhombus installation groove is precisely opened on the upper surface of the porous copper-based sintered layer according to the plan. Then, the oil-impregnated ceramic particle pre-embedded layer is prepared. During the manufacturing process, a special process is used to uniformly mix ceramic particle raw materials into the ceramic material. During the molding process, the process parameters are controlled to make the oil-impregnated ceramic particle pre-embedded layer form a rhombus shape and the surface naturally forms raised ceramic particles. Finally, the prepared rhombus-shaped oil-impregnated ceramic particle pre-embedded layer is accurately installed into the corresponding rhombus installation groove.

[0011] Furthermore, a first porous oil storage layer is installed on the lower surface of the top plate of the oil tank outer frame, and a second porous oil storage layer is installed on both inner walls of the oil tank outer frame. After the overall processing and assembly of the oil tank outer frame is completed, the first and second porous oil storage layer materials of appropriate sizes are cut according to the size specifications of the top plate and the inner walls of the oil tank outer frame. Then, the cut materials are pre-treated to ensure that their surfaces are flat and free of impurities. Then, a high-strength and oil-resistant adhesive is evenly applied to the lower surface of the top plate of the oil tank outer frame and the designated installation positions on the inner walls of both sides. The first porous oil storage layer is then accurately pasted onto the lower surface of the top plate, and the second porous oil storage layer is pasted onto the inner walls of both sides respectively. Appropriate pressure is applied during the pasting process to ensure that the porous oil storage layer is tightly attached to the oil tank outer frame. Finally, the adhesive is allowed to fully cure to complete the installation.

[0012] The beneficial effects of this invention are as follows: the outer frame of the oil tank can constrain the lubrication area and prevent lubricating oil from overflowing; the porous copper-based sintered layer has a porous structure that can store a certain amount of lubricating oil, providing a base oil quantity for self-lubrication; the oil-containing ceramic particle pre-embedded layer is evenly distributed on the surface of the porous copper-based sintered layer, and its oil-containing characteristics further increase the storage capacity of lubricating oil, and the uniform distribution can ensure the uniformity of lubrication; the oil holes evenly opened on the surface of the oil-containing ceramic particle pre-embedded layer facilitate the seepage of lubricating oil from the inside to the surface, continuously providing lubrication to the contact surface; the capillary oil guiding channels evenly distributed on the surface of the porous copper-based sintered layer can guide the stored lubricating oil to the parts that need lubrication through capillary action, ensuring the continuity and stability of lubrication, thereby effectively reducing the friction and wear between the hardware parts of the table saw and extending its service life.

[0020] The base 1 has an oil groove frame 2 on its upper surface, which can constrain the lubrication area and prevent lubricating oil from overflowing. The porous copper-based sintered layer 3 has a porous structure that can store a certain amount of lubricating oil, providing a base oil for self-lubrication. The oil-containing ceramic particle pre-embedded layer 4 is evenly distributed on the surface of the porous copper-based sintered layer 3. Its oil-containing characteristics further increase the storage capacity of lubricating oil, and its uniform distribution can ensure the uniformity of lubrication. The oil holes 5 evenly opened on the surface of the oil-containing ceramic particle pre-embedded layer 4 are conducive to the lubricating oil seeping from the inside to the surface, continuously providing lubrication to the contact surface. The capillary oil guiding channels 6 evenly distributed on the surface of the porous copper-based sintered layer 3 can guide the stored lubricating oil to the parts that need lubrication by using capillary action, ensuring the continuity and stability of lubrication, thereby effectively reducing the friction and wear between the hardware parts of the table saw and extending its service life.

[0021] The porous copper-based sintered layer 3 has transversely uniformly opened conveying channels 7 on its surface. The conveying channels 7 all penetrate the surface of the capillary oil guiding channels 6. After the porous copper-based sintered layer 3 is prepared, a precision machining process is used to open the conveying channels 7 transversely uniformly on its surface according to a predetermined spacing and direction. During the opening process, the machining accuracy is strictly controlled to ensure that each conveying channel 7 can accurately penetrate the surface of the capillary oil guiding channels 6 that are uniformly arranged on the surface of the porous copper-based sintered layer 3 in advance.

Then, the oil-impregnated ceramic particle pre-embedded layers 4 are accurately placed one by one into the mounting grooves 9, and appropriate pressure is applied to make them securely installed, ensuring that the oil-impregnated ceramic particle pre-embedded layer 4 and the mounting groove 9 are tightly fitted.

[0024] Both the oil-impregnated ceramic particle pre-embedded layer 4 and the mounting groove 9 are designed in a rhombus shape. The surface of the oil-impregnated ceramic particle pre-embedded layer 4 is provided with raised ceramic particles. After the preliminary processing of the porous copper-based sintered layer 3 is completed, the size, angle and spacing of the rhombus mounting groove 9 are planned according to the overall design requirements. Using equipment with high-precision processing capabilities, the rhombus mounting groove 9 is precisely opened on the upper surface of the porous copper-based sintered layer 3 according to the plan. Then, the oil-impregnated ceramic particle pre-embedded layer 4 is prepared. During the manufacturing process, a special process is used to uniformly mix ceramic particle raw materials into the ceramic material. During the molding process, the process parameters are controlled to make the oil-impregnated ceramic particle pre-embedded layer 4 form a rhombus shape and the surface naturally forms raised ceramic particles. Finally, the prepared rhombus-shaped oil-impregnated ceramic particle pre-embedded layer 4 is accurately installed into the corresponding rhombus mounting groove 9.

[0025] A first porous oil storage layer 10 is installed on the lower surface of the top plate of the oil tank outer frame 2, and a second porous oil storage layer 11 is installed on both inner walls of the oil tank outer frame 2. After the overall processing and assembly of the oil tank outer frame 2 is completed, the first porous oil storage layer 10 and the second porous oil storage layer 11 of appropriate size are cut according to the size specifications of the top plate and the inner walls of the oil tank outer frame 2. Then, the cut materials are pre-treated to ensure that their surfaces are flat and free of impurities. Then, a high-strength and oil-resistant adhesive is evenly applied to the lower surface of the top plate of the oil tank outer frame 2 and the designated installation positions on both inner walls. The first porous oil storage layer 10 is then accurately pasted onto the lower surface of the top plate, and the second porous oil storage layer 11 is pasted onto the inner walls of both sides respectively.
