Description

Technical Field

[0001] This invention relates to the field of milling and grinding machine technology, and more specifically, to a slide structure for a milling and grinding machine. Background Technology

[0002] The ram is a core component of the machine tool motion mechanism. It is usually connected to the slide via guide rails to form a linear motion mechanism, providing mounting support for the machine tool spindle system. This includes lathe turret bases, boring spindles of milling machines, gantry milling machines, and other scenarios, achieving machining functions through linear motion.

[0003] When the milling and grinding machine is working, the slide will generate a large friction force between it and the guide rail of the machine tool, which will cause the guide rail to wear easily after long-term operation. In addition, the milling and grinding machine will generate a lot of iron filings during operation. These iron filings will accumulate on the guide rail, which will greatly increase the friction force between the slide and the guide rail, making it difficult for the slide to move and accelerating wear.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In one possible embodiment, please refer to Figure 1 and Figure 2 As shown, a milling and grinding integrated machine slide 2 structure includes a machine tool 1 and a slide 2 that slides and engages with the machine tool 1. A grinding tool is provided on the side of the slide 2 closest to the machine tool 1 for grinding the workpiece. Symmetrically distributed guide rails 3 are provided on both sides of the machine tool 1. Multiple equally spaced grooves 301 are provided on the guide rails 3. The slide 2 is provided with sliding grooves 201 that slide and engage with the guide rails 3. The sliding of the slide 2 on the machine tool 1 is achieved through the sliding engagement of the sliding grooves 201 and the guide rails 3. A drive mechanism 10 is provided on the slide 2 to move the slide 2. The drive mechanism 10 includes a drive motor 1001 fixedly connected to the slide 2 and... A drive gear 1002 is located inside the slide 2 and rotates with the slide 2. The output end of the drive motor 1001 extends into the slide 2 and is fixedly connected to the drive gear 1002. A rack 302 is fixedly connected to the side of the guide rail 3 away from the machine tool 1. The drive gear 1002 meshes with the rack 302. The output of the drive motor 1001 can drive the drive gear 1002 to rotate, thereby driving the slide 2 to slide along the direction of the rack 302. The slide 2 is connected to the slide groove 201 with a ball bearing 205 that abuts against the guide rail 3. By setting the ball bearing 205, the friction between the slide 2 and the guide rail 3 can be effectively reduced.

[0026] For further details, please refer to Figure 2 and Figure 3 As shown, the slide block 2 is provided with an oil storage chamber 202, which stores lubricating oil. The oil storage chamber 202 is provided with an oil outlet 203 that communicates with the slide groove 201. Both the front and rear ends of the slide groove 201 are slidably connected with an oil outlet mechanism 4 for controlling the oil outlet 203. When the slide block 2 slides, the oil outlet mechanism 4 will dispense oil, thereby reducing the friction between the slide block 2 and the guide rail 3 and reducing the wear of the guide rail 3 and the slide block 2. At the same time, by providing the oil outlet mechanism 4 at both the front and rear ends of the slide groove 201, the slide block 2 can dispense oil whether it moves forward or backward.

[0027] For further details, please refer to Figure 2 , Figure 3 and Figure 4As shown, the oil outlet mechanism 4 includes a slider 401 that slides and engages with the slide block 2. The end of the slider 401 located outside the slide block 2 is arc-shaped. The slide block 2 is provided with a slide cavity 204 that slides and engages with the slider 401. Symmetrically distributed limiting blocks 402 are fixedly connected to the slider 401. The limiting blocks 402 abut against the inner wall of the slide cavity 204. By abutting against the inner wall of the slide cavity 204, the slider 401 is limited to prevent it from sliding out of the slide block 2. A connector 403 that extends into the oil storage cavity 202 is fixedly connected to the slider 401. A piston 404 that slides and engages with the oil storage cavity 202 is fixedly connected to the end of the connector 403 that is away from the slider 401.

[0028] For details, please refer to Figure 2 , Figure 3 and Figure 4 As shown, during the sliding process of the slide block 2, when the slider 401 is aligned with the groove 301, the piston 404 is located at the bottom of the oil storage chamber 202. When the slide block 2 slides, the groove 301 will abut against the end of the slider 401 located outside the slide block 2. The arc-shaped slider 401 can reduce the resistance between it and the groove 301. The slider 401 will slide upward in the slide chamber 204 under the force of the groove 301, thereby driving the piston 404 to move upward and squeezing the lubricating oil in the oil storage chamber 202 through the oil outlet 203. The lubricating oil will enter the groove 201 and the guide rail 3 through the oil outlet 203, thereby reducing the friction between the slide block 2 and the guide rail 3.

[0029] For further details, please refer to Figure 2 , Figure 3 and Figure 4 As shown, a first spring 405 is sleeved on the outer side of the connector 403. A first annular groove 406 and a second annular groove 407 are respectively provided on the opposite side of the slider 401 and the slide cavity 204. The two ends of the first spring 405 are respectively engaged with the first annular groove 406 and the second annular groove 407. The first annular groove 406 and the second annular groove 407 will limit the first spring 405, ensuring that the elastic force of the first spring 405 acts on the upper and lower ends. When the slide block 2 moves back to the slider 401 and the groove 301 are aligned, the slider 401 will rebound under the action of the first spring 405, so that the slider 401 slides out of the slide block 2 again. At this time, the piston 404 is driven to move down.

[0030] For further details, please refer to Figure 2 , Figure 3 and Figure 4As shown, the oil storage chamber 202 includes an upper chamber 2021 and a lower chamber 2022. The piston 404 is located in the lower chamber 2022. A connection port 2023 is provided between the upper chamber 2021 and the lower chamber 2022. The oil outlet 203 is located in the lower chamber 2022 on the side near the upper chamber 2021. Both the connection port 2023 and the oil outlet 203 are equipped with a one-way valve 408. That is, when the piston 404 moves down, the lubricating oil in the lower chamber 2022 flows through... The oil is discharged through the outlet 203. At this time, the pressure in the lower cavity 2022 decreases. The lubricating oil in the upper cavity 2021 will enter the lower cavity 2022 through the one-way valve 408 to replenish it under the action of gravity and atmospheric pressure. When the slide 2 moves again and the slider 401 slides upward again, the lubricating oil in the lower cavity 2022 will be discharged again, thus ensuring that the slide 2 will always have oil flowing out during the sliding process, effectively reducing the friction between the slide 2 and the guide rail 3.

[0031] For further details, please refer to Figure 2 , Figure 3 and Figure 4 As shown, collection plates 6 are fixedly connected to both sides of the guide rail 3. A collection trough 7 connected to the collection plate 6 is provided on one side of the guide rail 3. A filter device 8 is provided in the collection trough 7. An oil inlet tank 11 is provided above the collection trough 7. An oil inlet pipe 9 connected to the oil storage chamber 202 is provided on the oil inlet tank 1. An oil inlet port 2024 connected to the oil inlet pipe 9 is provided in the upper chamber 2021. A through pipe 206 is fixedly connected between adjacent upper chambers 2021. The collection plate 6 is inclined and the lowest point of the collection plate 6 is connected to the collection trough 7. The filter device 8 of the collection trough 7 is located on the side close to the collection plate 6. Excess lubricating oil squeezed out by the oil outlet mechanism 4 will be squeezed onto the collection plates 6 on both sides by the action of the slide bolster 2 and enter the collection trough 7 through the filter device 8 under the action of gravity. The lubricating oil in the collection trough 7 is put into the oil inlet tank 11 and re-enters the oil storage chamber 202 through the oil inlet pipe 9, realizing the reuse of lubricating oil and reducing resource waste.

[0032] For further details, please refer to Figure 2 , Figure 3 and Figure 6 As shown, the filter device 8 includes a filter screen 801 slidably connected to the collection tank 7. The two ends of the filter screen 801 are fixedly connected to symmetrically distributed fixing blocks 802. The collection tank 7 is provided with a limiting groove 701 that slidably engages with the fixing blocks 802. The filter screen 801 can filter iron filings. The filter screen 801 is installed by the sliding engagement of the fixing blocks 802 and the limiting groove 701. There are two sets of limiting grooves 701, which are distributed vertically. When there are too many iron filings, a new filter screen 801 can be inserted into the lower limiting groove 701, and the upper filter screen 801 can be removed for cleaning. This can effectively prevent iron filings from flowing in when the filter screen 801 is being cleaned.

[0033] For further details, please refer to Figure 2 , Figure 3 and Figure 5 As shown, a limit valve 901 is slidably connected inside the oil inlet pipe 9, and a limit ring 902 is fixedly connected to the oil inlet pipe 9. The limit valve 901 has a guide surface 903 that abuts against the limit ring 902 on the side near the limit ring 902. A fixed seat 904 is fixedly connected inside the oil inlet pipe 9. The limit valve 901 and the fixed seat 904 are slidably engaged. A second spring 905 is provided between the limit valve 901 and the fixed seat 904. A connecting pipe 207 is fixedly connected to the slide ram 2. The connecting pipe 207 is connected to the oil inlet 2024. The oil inlet pipe 9 and the connecting pipe 207 are slidably engaged. A support seat 2071 is fixedly connected inside the connecting pipe 207. A support rod 2072 that abuts against the limit valve 901 is fixedly connected to the support seat 2071. Both the support seat 2071 and the fixed seat 904 are provided with through grooves 906 for the flow of lubricating oil.

[0034] For details, please refer to Figure 2 , Figure 3 and Figure 5 As shown, when the slide ram 2 moves to the side of the guide rail 3 where the oil inlet tank 11 is located, the connecting pipe 207 is slidably connected to the oil inlet pipe 9. At this time, the support rod 2072 inside the connecting pipe 207 abuts against the limit valve 901 inside the oil inlet pipe 9, causing the limit valve 901 to slide and separate from the limit ring 902. At this time, the lubricating oil can enter the upper cavity 2021 through the through groove 906 on the fixed seat 904 and the support seat 2071 to replenish the lubricating oil in the upper cavity 2021. When the slide ram 2 slides away from the side of the oil inlet tank 11, the connecting pipe 207 separates from the oil inlet pipe 9. At this time, the limit valve 901 will rebound under the action of the spring, so that the guide surface 903 abuts against the limit ring 902 again, thereby limiting the lubricating oil in the oil inlet tank 11 and preventing lubricating oil leakage.

[0035] For further details, please refer to Figure 2 and Figure 3 As shown, scrapers 5 are fixedly connected to both the front and rear ends of the slide block 2 and abut against the guide rail 3. The scrapers 5 can clean the iron filings. The iron filings will enter the groove 301 and the collection plate 6 under the action of the scrapers 5. A conical protrusion 12 is slidably connected to the groove 301. A third spring 1201 is fixedly connected between the conical protrusion 12 and the guide rail 3. The iron filings that enter the groove 301 will slide to both sides under the action of the conical protrusion 12 and slide into the collection plate 6. At the same time, the elastic coefficient of the third spring 1201 is less than the elastic coefficient of the first spring 405. Therefore, when the slider 401 slides to the groove 301, the conical protrusion 12 will slide down under the action of the slider 401, without affecting the oil output of the oil output mechanism 4.
