Abstract
Description
Technical Field
[0001] This application relates to the technical field of support seats, and in particular to a feed rail seat. Background Technology
[0002] In the industrial sector, grinding and polishing machines are indispensable as efficient and precise surface treatment equipment, widely used in many core industrial sectors such as metal processing, electronics manufacturing, optical component production, and ceramics manufacturing. Through fine grinding and polishing processes, they significantly improve the surface finish and processing accuracy of workpieces, making them a key tool for driving leaps in product quality and improving production efficiency.
[0003] Among existing technologies, a diamond grinding and polishing machine design disclosed in Chinese patent CN105234777A is particularly noteworthy. This design ingeniously integrates a stable base, a flexible sliding guide rail, a precisely positioned roller base, and a high-efficiency roller, collectively constructing a processing platform that is both stable and flexible. The precise positioning of the roller not only ensures axial and radial stability but also provides the ability to rotate freely in the circumferential direction, laying a solid foundation for the fine processing of high-precision materials such as water drills. Furthermore, the design highlight of the sliding guide rail lies in the perfect cooperation between its parallel guide rails on both sides and the sliding guide blocks; this innovation greatly enhances the flexibility and precision control during the processing.
[0004] However, it is worth noting that although the design has demonstrated excellent performance in many aspects, a potential technical problem has gradually emerged during long-term application: due to continuous sliding friction, the stability of the moving guide block when moving on the slide rail on the inclined side of the floating guide seat has decreased. At the same time, the wear of the contact surface between the moving guide block and the guide rail has intensified. This not only affects the machining accuracy but also shortens the service life of the moving guide block, indicating room for improvement. Utility Model Content
[0005] The purpose of this application is to provide a feed line support that solves the problems of instability and severe wear of the moving guide block during the sliding process of the traveling line support in the aforementioned related technologies.
[0006] The feed line support provided in this application adopts the following technical solution: A feed line rail seat includes a rail seat body with two opposing sides forming supporting inclined surfaces. A plurality of parallel guide rail seats are fixed on the supporting inclined surfaces. A plurality of lubrication holes are formed on the guide rail seats. An installation cavity communicating with the lubrication holes is formed inside the rail seat body. An oil box is fixed on the inner wall of the installation cavity. An oil supply pipe connected to an external oil supply pump is provided on the oil box. An oil outlet corresponding to the lubrication hole is formed on the oil box. The outer edge of the oil outlet abuts against the inner edge of the lubrication hole. A sealing element is provided on the inner wall of the oil outlet for controlling the opening and closing of the oil outlet.
[0007] By adopting the above technical solution, when the oil supply pump supplies oil to the oil box through the oil supply pipe, the sealing component opens to allow the oil to flow from the oil outlet and lubrication hole to the upper surface of the guide rail seat, thereby lubricating the guide rail seat; when no oil is supplied, the sealing component blocks the oil outlet; due to the application and setting of the oil box and sealing component, the friction and equipment wear during the application process are reduced.
[0008] Optionally, a plurality of fixing ears are fixed on the side of the oil box, and fixing ears are provided with fixing through holes. The inner wall of the mounting cavity is provided with fixing thread grooves, and fixing screws are provided in the mounting cavity in sequence, passing through the fixing through holes and screwed into the fixing thread grooves.
[0009] By adopting the above technical solution, when the oil box is installed and fixed, first adjust the opening of the oil outlet and the lubrication hole on the oil box to coincide and abut, and then use the fixing screw to pass through the fixing through hole and screw it into the fixing thread groove, so as to achieve the installation and fixing of the oil box.
[0010] Optionally, a limiting groove is formed at the opening edge of the oil outlet facing the lubrication hole, and the sealing component includes a plurality of elastic pads fixed on the inner wall of the limiting groove. The sides of adjacent elastic pads abut against each other, and the elastic pads can be elastically bent under the oil pressure when the oil supply pump supplies oil.
[0011] By adopting the above technical solution, due to the setting of the elastic pad, when the oil supply pump supplies oil to the oil box, the elastic pad is elastically bent under the action of oil pressure, thereby opening the oil outlet; when the oil supply stops, the elastic pad resets and the oil outlet is resealed.
[0012] Optionally, the cross-sectional thickness of the elastic pad is greater than the depth of the limiting groove, a portion of the elastic pad protrudes from the limiting groove, and the side of the elastic pad away from the oil box abuts against the inner wall of the mounting cavity.
[0013] By adopting the above technical solution, during the installation of the oil box, the elastic pad protrusion is pressed and pressed against the inner wall of the installation cavity through the cooperation of the elastic pad protrusion. This reduces the possibility of oil leakage from the connection between the lubrication hole and the oil outlet.
[0014] Optionally, a positioning groove is provided on the inner edge of the opening of the lubrication hole facing the oil box for the insertion of the protruding part of the elastic pad, and the protruding part of the elastic pad abuts against the inner wall of the positioning groove.
[0015] By adopting the above technical solution, during the installation of the oil box, the cooperation between the protruding part of the elastic pad and the positioning groove can reduce the possibility of oil leakage from the connection between the lubrication hole and the oil outlet, and also play a role in pre-positioning, making it easier to install and fix the oil box.
[0016] Optionally, the inner edge of the opening of the positioning groove is a guide slope.
[0017] By adopting the above technical solution, the protruding part of the elastic pad can be easily inserted into the positioning groove along the guide slope.
[0018] Optionally, the main body of the rail base has several lifting holes on the supporting inclined surface.
[0019] By adopting the above technical solution, due to the setting of the lifting hole, the feed line rail seat can be lifted to a certain height by the lifting equipment before the oil box can be installed, reducing the installation difficulty of the oil box; it also facilitates the subsequent installation and application of the feed line rail seat.
[0020] Optionally, the number of guide rail seats on the same support slope is not less than four sets.
[0021] By adopting the above technical solutions, the stability of the corresponding equipment when sliding on the supporting inclined surface is improved.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Due to the application and design of the oil box and the sealing component, when the oil supply pump supplies oil to the oil box through the oil supply pipe, the sealing component opens to allow the oil to flow from the oil outlet and lubrication hole to the upper surface of the guide rail seat, thereby lubricating the guide rail seat; when no oil is supplied, the sealing component blocks the oil outlet; thereby reducing friction and equipment wear during application.

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.
[0027] Example: Reference Figure 1 , Figure 2 and Figure 3 A feed line rail seat includes a rail seat body 1, wherein the two opposite sides of the rail seat body 1 are support slopes 11, and four sets of parallel guide rail seats 12 (two long and one short) are integrally formed on the support slopes 11. A plurality of lubrication holes 13 are evenly opened on the guide rail seats 12, and an installation cavity 14 communicating with the lubrication holes 13 is opened in the rail seat body 1. An oil box 2 corresponding to the guide rail seat 12 is fixed on the inner wall of the mounting cavity 14. The oil box 2 is provided with an oil supply pipe 21 (hose) connected to an external oil supply pump. An oil outlet 22 corresponding to the lubrication hole 13 is opened on the oil box 2. The outer edge of the oil outlet 22 abuts against the inner edge of the lubrication hole 13. A sealing member 23 is provided on the inner wall of the oil outlet 22. The sealing member 23 is used to control the opening and closing of the oil outlet 22. When the oil supply pump supplies oil to the oil box 2 through the oil supply pipe 21, the sealing component 23 opens to allow the oil to flow from the oil outlet 22 and the lubrication hole 13 to the upper surface of the guide rail seat 12, thereby lubricating the guide rail seat 12; when no oil is supplied, the sealing component 23 blocks the oil outlet 22 to reduce friction and equipment wear during application.
[0028] Reference Figure 3 and Figure 4A limiting groove 221 is provided at the opening edge of the oil outlet 22 facing the lubrication hole 13. The sealing component 23 includes four fan-shaped elastic pads 231 fixed on the inner wall of the limiting groove 221. The elastic pads 231 are made of rubber, and the sides of adjacent elastic pads 231 abut against each other. When the oil pump supplies oil, the elastic pads 231 bend elastically under the action of oil pressure, thereby opening the oil outlet 22. When the oil supply stops, the elastic pads 231 reset, and the oil outlet 22 is resealed.
[0029] Reference Figure 3 and Figure 4 The cross-sectional thickness of the elastic pad 231 is greater than the depth of the limiting groove 221. A portion of the elastic pad 231 protrudes from the limiting groove 221. A positioning groove 131 is provided on the inner edge of the opening of the lubrication hole 13 facing the oil box 2 for the protruding portion of the elastic pad 231 to be inserted. The protruding portion of the elastic pad 231 abuts against the inner wall of the positioning groove 131. The inner edge of the opening of the positioning groove 131 is a guide slope 132, which makes it easy for the protruding part of the elastic pad 231 to be inserted into the positioning groove 131 along the guide slope 132. At the same time, during the installation of the oil box 2, the cooperation between the protruding part of the elastic pad 231 and the positioning groove 131 can also play a role in pre-positioning, making it easier to install and fix the oil box 2.
[0030] Reference Figure 5 and Figure 6 Two fixing ears 24 are fixed on opposite sides of the oil box 2. The fixing ears 24 are provided with fixing through holes 241. The inner wall of the mounting cavity 14 is provided with fixing thread grooves 141. The mounting cavity 14 is provided with fixing screws 3 that pass through the fixing through holes 241 and are screwed into the fixing thread grooves 141 in sequence, thereby realizing the installation and fixing of the oil box 2.
[0031] Reference Figure 1 and Figure 2 The main body 1 of the rail seat has two lifting holes 111 on the supporting inclined surface 11, which facilitates the subsequent installation and application of the feed line rail seat; it also allows the oil box 2 to be installed after the feed line rail seat is lifted to a certain height by the lifting equipment, reducing the installation difficulty of the oil box 2.
[0032] The implementation principle of this application embodiment is as follows: When the oil supply pump supplies oil to the oil box 2 through the oil supply pipe 21, the elastic pad 231 bends elastically under the action of oil pressure, thereby opening the oil outlet 22, allowing the oil to flow from the oil outlet 22 and the lubrication hole 13 to the upper surface of the guide rail seat 12, thus lubricating the guide rail seat 12; when the oil supply pump stops supplying oil, the elastic pad 231 resets, the sides of the adjacent elastic pads 231 that are close to each other abut against each other again, and the oil outlet 22 is blocked again.
