Description

Technical Field

[0001] This invention relates to the structure of machining equipment, and particularly to a machine tool. Background Technology

[0002] The machine tool is equipped with a turntable, which includes a base and a cradle. The cradle can be rotated, and a self-rotating component can also be installed on the cradle. This allows the workpieces waiting to be processed on the self-rotating component to be adjusted arbitrarily, making it convenient for the machine tool to process the workpiece at multiple positions and angles.

[0003] However, the cutting fluid can spray onto the connection between the base and the cradle, causing water to enter the turntable and affecting its lifespan.

[0012] A machine tool according to an embodiment of the present invention has at least the following beneficial effects:

[0013] 1. The waterproof structure of the present invention, by setting a first vertical ring, can block the cutting fluid and prevent the cutting fluid from directly rushing to the connection between the base and the cradle, that is, prevent the cutting fluid from directly rushing to the connection between the horizontal rotating shaft and the horizontal hole.

[0014] 2. The waterproof structure of the present invention provides a second vertical ring, which can block the cutting fluid from splashing from the inside of the first vertical ring to the horizontal hole, allowing the splashed cutting fluid to flow downward along the second vertical ring and preventing the cutting fluid from splashing into the horizontal hole.

[0015] 3. The waterproof structure of the present invention, by setting drainage channels, can discharge cutting fluid that flies into the inner side of the first vertical ring, and in particular, discharge cutting fluid blocked by the second vertical ring, so as to avoid cutting fluid accumulating in the gap between the first vertical ring and the base, and to prevent the continuous accumulation of cutting fluid from affecting the waterproof effect.

[0016] 4. The self-locking structure of this invention, by setting a separation chamber, allows the compressed gas or liquid in the separation chamber to push the sliding member away from the brake member when the machine tool is not powered off. This does not hinder the brake member and the horizontal rotating shaft from rotating together, nor does it affect the cradle's tilting, such as tilting for ascent or tilting for descent. However, when the machine tool suddenly loses power, the compressed gas and liquid cannot maintain their original pressure. Therefore, under the action of the reset member, the sliding member moves closer to the brake member, and the gas or liquid in the separation chamber is discharged out of the separation chamber. Due to the contact friction between the sliding member and the brake member, the rotation of the brake member and the horizontal rotating shaft can be suppressed, achieving self-locking. Furthermore, since the self-locking structure is located between the horizontal rotating shaft and the horizontal hole, it does not occupy the external space of the turntable, reducing space requirements and resulting in a simple and compact structure.

[0024] A machine tool according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0025] Reference Figure 1 This invention aims to provide an embodiment of a machine tool. In this embodiment, the machine tool mainly includes a bed, a rotary table 100, a chip conveyor 200, and a crossbeam. The bed is typically manufactured from a cast bed base 300, forming the mounting base of the machine tool. The rotary table 100 is mounted on the worktable of the bed, allowing the workpiece to be rotated or flipped to meet machining requirements. The crossbeam is typically manufactured from a cast movable beam base 400, allowing longitudinal movement of the crossbeam while the machine tool's cutting tool can move laterally along the crossbeam. Therefore, machining requirements can be met without requiring horizontal displacement of the rotary table 100.

[0026] Reference Figure 2 and Figure 3 This invention aims to provide an embodiment of a rotary table 100. Structurally, the rotary table 100 includes a base 1 and a cradle 2, with the cradle 2 connected to the base 1 at two points, thereby stably supporting the cradle 2 and preventing it from shaking during machining. Structurally, the cradle 2 has a horizontal rotating shaft 3, and the base 1 has a horizontal hole 4 for accommodating the horizontal rotating shaft 3. In some embodiments, a self-rotating component can be provided on the cradle 2, thereby achieving multi-directional adjustment of the product through compound rotation and improving the machining capability of the machine tool.

[0027] Reference Figure 3 The present invention aims to provide an embodiment of a waterproof structure for a turntable 100, which is applied at the connection between the cradle 2 and the base 1.

[0028] In detail, the waterproof structure includes a first vertical ring 5 and a second vertical ring 6. The outer side of the first vertical ring 5 is sealed to the base 1, and the inner side of the first vertical ring 5 accommodates a horizontal rotating shaft 3 that passes through a horizontal hole 4. The second vertical ring 6 is located between the first vertical ring 5 and the base 1, and is fitted onto the horizontal rotating shaft 3. The outer edge of the second vertical ring 6 and the inner edge of the first vertical ring 5 overlap along the axial direction of the horizontal rotating shaft 3. A drainage channel is provided at the bottom of the first vertical ring 5. By setting the first vertical ring 5, the cutting fluid can be blocked, preventing it from directly rushing towards the connection between the base 1 and the cradle 2, that is, preventing the cutting fluid from directly rushing towards the connection between the horizontal rotating shaft 3 and the horizontal hole 4. By setting the second vertical ring 6, when the cutting fluid splashes from the inner side of the first vertical ring 5 towards the horizontal hole 4, the second vertical ring 6 can block it, allowing the splashed cutting fluid to flow downwards along the second vertical ring 6, preventing the cutting fluid from splashing into the horizontal hole 4. By setting up drainage channels, cutting fluid that flies into the inner side of the first vertical ring 5 can be discharged, especially cutting fluid blocked by the second vertical ring 6, to prevent cutting fluid from accumulating in the gap between the first vertical ring 5 and the base 1, and to prevent the continuous accumulation of cutting fluid from affecting the waterproof effect.

[0029] In some embodiments, the base 1 may include a base ring 7, with a first vertical ring 5 mounted on one side of the base ring 7, and a sealing ring 8 disposed on the inner side of the base ring 7. The sealing ring 8 is fitted onto the horizontal rotating shaft 3. By providing the sealing ring 8, a seal can be achieved between the horizontal rotating shaft 3 and the horizontal hole 4, preventing cutting fluid from seeping into the interior of the base 1 and avoiding corrosion of the rotating mechanism. The first vertical ring 5 and the second vertical ring 6 can reduce the chance of cutting fluid contacting the sealing ring 8, extending the service life of the sealing ring 8. In some embodiments, the base ring 7 may include an end ring portion and a bushing portion. The end ring portion is fitted with the first vertical ring 5, and the bushing portion is located in the direction opposite to the first vertical ring 5 of the end ring portion. A mounting groove 9 for accommodating the sealing ring 8 is provided at the connection between the end ring portion and the bushing portion. By providing the end ring portion, the need for installing the second vertical ring 6 can be met. By providing the bushing portion, the mating length between the base ring 7 and the horizontal rotating shaft 3 can be extended, improving the reliability of the seal. At the same time, it is also convenient to provide the mounting groove 9 to meet the need for installing the sealing ring 8. In some embodiments, the sealing ring 8 may have a deformable annular groove 10 and an inner ring 12 and an outer ring 11 forming the deformable annular groove 10. The deformable annular groove 10 is disposed away from the first vertical ring 5. The inner surface of the inner ring 12 abuts against the horizontal rotating shaft 3, and the outer surface of the outer ring 11 abuts against the inner surface of the base ring 7. By providing the deformable annular groove 10 and the inner ring 12 and outer ring 11 forming the deformable annular groove 10, the sealing ring 8 has an elastic deformation capacity exceeding that of its own material. The inner ring 12 can fit well against the horizontal rotating shaft 3, while the outer ring 11 can fit well against the mounting annular groove 9, thereby improving the sealing capacity.

[0030] In some embodiments, the inner ring 12 may have a lip and two bevels forming the lip on the side near the horizontal rotating shaft 3. By providing the lip and two bevels, the contact between the inner ring 12 and the horizontal rotating shaft 3 can be reduced, thus reducing wear. Simultaneously, the bevels elastically contact the horizontal rotating shaft 3, ensuring that the sealing effect is not affected during rotation. In some embodiments, the first vertical ring 5 may have a first inner step 13 and a second inner step 14 on the side near the base 1. The area enclosed by the first inner step 13 is used to accommodate the second vertical ring 6, and the area enclosed by the second inner step 14 is used to form a gap between the second vertical ring 6 and the base 1. The first inner step 13 and the second inner step 14 provide space for setting the gap and installing the second vertical ring 6, meeting design requirements while reducing manufacturing difficulty.

[0031] In some embodiments, a groove may be provided on the side of the first vertical ring 5 near the base 1. The groove is located at the bottom of the first vertical ring 5 and connects the inner and outer sides of the first vertical ring 5. By providing the groove, a drainage channel is formed by the groove and the side of the base 1, reducing manufacturing difficulty. At the same time, the drainage channel has a large cross-sectional dimension, which facilitates drainage and chip removal. In some embodiments, the first vertical ring 5 may include an upper half ring and a lower half ring. By making the first vertical ring 5 consist of two half rings, assembly and maintenance are facilitated, and workload is reduced. At the same time, cutting fluid is less likely to seep in at the connection between the upper half ring and the lower half ring. In some embodiments, the first vertical ring 5 may include a left half ring and a right half ring. By making the first vertical ring 5 include a left half ring and a right half ring, it is also convenient to install from both sides of the base 1, which facilitates operation. At the same time, it avoids affecting the strength of the half ring by providing a drainage channel.

[0032] In some embodiments, the cradle 2 may have a basket body 15, which includes a mounting end 16 connecting to the horizontal rotating shaft 3. The mounting end 16 is used to mount the second vertical ring 6. By providing the mounting end 16, different processing needs can be met by replacing different basket bodies 15 without changing the connection between the horizontal rotating shaft 3 and the horizontal hole 4. Moreover, mounting the second vertical ring 6 at the mounting end 16 is easy to implement and requires minimal modification to the horizontal rotating shaft 3. In some embodiments, the mounting end 16 may have a first outer step 17, with the inner edge of the first vertical ring 5 located within the area enclosed by the first outer step 17. By providing the first outer step 17, the first outer step 17 and the first vertical ring 5 cooperate to form a second overlap, reducing the probability of cutting fluid entering the inner side of the first vertical ring 5 and further improving the waterproof effect.

[0033] Reference Figure 1 , Figure 2 and Figure 4The present invention also aims to provide an embodiment of a self-locking structure for a turntable 100. In this embodiment, the self-locking structure of the turntable 100 can achieve self-locking of the turntable 100, preventing the cradle 2 from falling due to a sudden power outage during the climbing or descending process.

[0034] Specifically, a self-locking structure is provided between the horizontal hole 4 and the horizontal rotating shaft 3. The self-locking structure includes a brake 18, a sliding member 19, and a reset member 20. The brake 18 is fixed to the horizontal rotating shaft 3, and the sliding member 19 can move along the axis of the horizontal rotating shaft 3. The reset member 20 is used to drive the sliding member 19 to abut against the brake 18, so that the sliding member 19, the brake 18, and the horizontal rotating shaft 3 are stationary. A separation cavity 21 is formed between the sliding member 19 and the horizontal hole 4. The separation cavity 21 is connected to an external air source or liquid source. When the separation cavity 21 is filled, the separation cavity 21 drives the sliding member 19 to disengage from the brake 18. By providing the separation cavity 21, when the machine tool is not powered off, the compressed gas or liquid in the separation cavity 21 will push the sliding member 19 away from the brake 18, which does not hinder the brake 18 and the horizontal rotating shaft 3 from rotating together, nor does it affect the tilting of the cradle 2, such as tilting for climbing or tilting for descending. When the machine tool suddenly loses power, the compressed gas and liquid cannot maintain their original pressure. Therefore, under the action of the reset member 20, the sliding member 19 moves closer to the brake member 18. At the same time, the gas or liquid in the separation chamber 21 will be discharged out of the separation chamber 21. Due to the contact friction between the sliding member 19 and the brake member 18, the rotation of the brake member 18 and the horizontal rotating shaft 3 can be suppressed, achieving self-locking. At the same time, since the self-locking structure is set between the horizontal rotating shaft 3 and the horizontal hole 4, it does not occupy the external space of the turntable 100, reducing the space occupied and making the structure simple and compact.

[0035] In some embodiments, the base 1 may be provided with an air inlet 31 to facilitate the use of compressed air for self-locking arrangement. In some embodiments, the sliding member 19 may include a sliding ring, and a fixing ring 30 may be provided in the horizontal hole 4. The fixing ring 30 and the sliding ring overlap and seal on the side near the horizontal rotating shaft 3, and the fixing ring 30 and the sliding ring are used to mate with the horizontal hole 4 to form a separation cavity 21. By providing the fixing ring 30, the separation cavity 21 can be easily formed between the fixing ring 30 and the sliding ring. At the same time, by moving the sliding ring closer to or further away from the fixing ring 30, the size of the separation cavity 21 can be changed, reducing the difficulty of setting the separation cavity 21. Meanwhile, the overlap of the fixing ring 30 and the sliding ring on the side near the horizontal rotating shaft 3 can also maintain the seal of the separation cavity 21, preventing the separation cavity 21 from leaking compressed gas or liquid.

[0036] In some embodiments, the fixed ring 30 and the sliding ring can overlap and seal on the side near the horizontal rotating shaft 3. The fixed ring 30 and the sliding ring are used to mate with the horizontal hole 4 to form a separation cavity 21. The sliding ring has a convex ring 22, an outer ring portion 23 located inside the convex ring 22, and an inner ring portion 24 located inside the convex ring 22. The convex ring 22 is located on the side of the fixed ring 30 near the horizontal rotating shaft 3. A sealing ring is provided between the outer surface of the convex ring 22 and the inner surface of the fixed ring 30. The outer ring portion 23 is used to form the separation cavity 21. By having the sliding ring have a convex ring 22, it is convenient to achieve the overlap of the fixed ring 30 and the sliding ring. At the same time, by providing the outer ring portion 23, the separation cavity 21 can have a larger volume without increasing the distance between the sliding ring and the fixed ring 30 due to volume reasons.

[0037] In some embodiments, the end face of the inner ring portion 24 can be used to abut against the brake member 18 along the axial direction of the horizontal rotating shaft 3 for self-locking. By providing the inner ring portion 24 so that its end face is used to abut against the brake member 18, the contact structure between the sliding ring and the brake member 18 can be simplified. At the same time, it ensures that the sliding ring has a larger area to contact the brake member 18, thereby improving the self-locking capability.

[0038] In some embodiments, the horizontal hole 4 may be provided with a retaining ring 30, including: the horizontal hole 4 includes a countersunk hole, the retaining ring 30 is provided at the connection between the large-diameter section and the small-diameter section of the countersunk hole, and a sliding ring is provided on the small-diameter section of the countersunk hole. By providing a countersunk hole, the retaining ring 30 can be easily installed, reducing the difficulty of setting the retaining ring 30. At the same time, it is convenient to use the retaining ring 30 and the small-diameter section of the countersunk hole to complete the sealing of the separation cavity 21, and it is convenient to limit the sliding member 19, reducing the difficulty of manufacturing and arrangement. In some embodiments, the horizontal hole 4 may be provided with a retaining sleeve 25, which is located on the side of the retaining ring 30 facing away from the sliding ring. By providing the retaining sleeve 25, the solid forming the horizontal hole 4 can be supported, the strength of the base 1 can be improved, and the bending of the horizontal rotating shaft 3 can be reduced.

[0039] In some embodiments, the braking element 18 may include a braking ring, which is fitted onto the horizontal rotating shaft 3 and located inside the fixed ring 30. By having the braking element 18 with a braking ring and positioning it inside the fixed ring 30, on the one hand, it facilitates the contact between the end face of the braking ring and the end face of the inner ring portion 24, ensuring reliable and effective self-locking; on the other hand, it allows the fixed ring 30 and the braking ring to coincide in the radial direction of the horizontal rotating shaft 3, reducing the space occupied by the self-locking structure in the axial direction of the horizontal rotating shaft 3, making the self-locking structure more compact and occupying less space. In some embodiments, sealing rings or sealing rings may be provided between the fixed sleeve 25 and the horizontal hole portion 4, between the fixed ring 30 and the horizontal hole portion 4, between the sliding ring and the horizontal hole portion 4, and between the fixed ring 30 and the sliding ring, thereby satisfying the need for internal and external separation sealing and ensuring the sealing of the separation cavity 21. In some embodiments, the reset element 20 may include an outer ring and a plurality of reset arms connecting the inner side of the outer ring, with the plurality of reset arms connecting one of the fixed ring 30 and the sliding ring, and the outer ring connecting the other of the fixed ring 30 and the sliding ring.

[0040] In some embodiments, the reset member 20 may include an inner ring, a plurality of reset arms connecting the outer side of the inner ring, the plurality of reset arms connecting one of the fixed ring 30 and the sliding ring, and the inner ring connecting the other of the fixed ring 30 and the sliding ring. By including reset arms, an inner ring, or an outer ring in the reset member 20, an elastic reset member 20 can be arranged in a limited space. At the same time, due to the large number of reset arms, a large force can be generated to quickly move the sliding ring closer to the brake member 18, thereby quickly self-locking and preventing the cradle 2 from falling.

[0041] Meanwhile, considering the overlapping of the sliding ring and the fixed ring 30, as shown in the reference... Figure 4 As shown, the sliding ring has a convex ring 22, which facilitates the use of a reset component 20 with an outer ring. The reset arm is inserted into the annular groove outside the convex ring 22, making installation convenient. The reset component 20 can be replaced or selected as needed to improve versatility.

[0042] In some embodiments, one of the fixed ring 30 and the sliding ring may have an end face annular groove 26 or annular step for connecting the reset member 20, and the other of the fixed ring 30 and the sliding ring may have a radial annular groove 27 for connecting the reset member 20. By providing the end face annular groove 26 or annular step, it is convenient to connect the inner or outer ring to fix the reset member 20, and convenient to set the snap-fit ​​reset arm by providing the radial annular groove 27, simplifying installation and connection, and facilitating manufacturing. In some embodiments, the brake member 18 may include a brake ring 28 and an elastic ring 29 coaxially arranged. The brake ring 28 is mounted on the horizontal rotating shaft 3, and the elastic ring 29 is mounted on the brake ring 28, and the elastic ring 29 is used to abut against the sliding member 19. By having the brake ring 28 and the elastic ring 29 in the brake member 18, it is also convenient to keep the sliding ring in contact with the brake member 18, improving the reliability of self-locking and preventing wear of the brake member 18 from causing self-locking failure. In some embodiments, the elastic ring 29 may be set with reference to the reset member 20, increasing the strength and deformation range of the elastic ring 29.

[0043] Reference Figure 1 and Figure 5 The present invention also aims to provide an embodiment of a chip conveyor 200. In this embodiment, the chip conveyor 200 can be applied to various machine tools, including milling machines, lathes, etc., with preference given to milling machines, which are the most numerous type of machine tool.

[0044] Reference Figure 6 In this embodiment, the basic chip conveyor 200 includes a chip conveying device 32, which includes a conveyor chain for conveying chips. The conveyor chain includes a horizontal conveying section 33 and an inclined conveying section 34 arranged sequentially, with the lower end of the inclined conveying section 34 located close to the horizontal conveying section 33. Therefore, when the machine tool is working, the chips generated during machining, the cutting fluid and cooling oil used in machining will fall together to the horizontal conveying section 33. Then, during the conveying process of the conveyor chain, the cutting fluid and cooling oil will fall from the gaps and sides of the horizontal conveying section 33, separating the cutting fluid and cooling oil from the large chip particles, while the large chip particles remain on the horizontal conveying section 33. Next, the horizontal conveying section 33 conveys the chips to the inclined conveying section 34, lifting the chips and facilitating their fall from the top of the inclined conveying section 34, thus collecting the chips in the carriage.

[0045] Reference Figure 5 and Figure 7The chip removal device 32 in this embodiment also includes a chip guide 35 and a chip guide box 36. The chip guide 35 is mounted on the machine tool and has a chip guide channel inside, which connects to the interior of the machine tool and is used to remove chips from the machine tool. In some embodiments, the chip guide channel of the chip guide 35 can accommodate a section of the machine tool's chip removal screw, thereby allowing chips to pass smoothly through the chip guide channel and preventing insufficient cutting fluid flow from making it difficult to flush chips out of the chip guide channel. In some embodiments, the chip guide 35 can be a round tube, square tube, etc., for ease of manufacturing, and at the same time, increasing the cross-sectional area of ​​the chip guide channel facilitates chip removal. In some embodiments, the chip guide 35 is preferably a square tube with an outwardly protruding edge at the end, which is bolted to the machine tool base, reducing installation difficulty and increasing the horizontal dimension for easier chip removal. Furthermore, the preferred square tube design of the chip guide 35 facilitates matching with the chip guide box 36, reducing gaps, reducing cutting fluid evaporation, and reducing losses.

[0046] The chip guide box 36 is used to receive chips discharged from the chip guide channel, and includes a first box section 37 and a first box cover 38 covering the first box section 37. The first box section 37 is preferably a double-layer structure, thereby meeting the support requirements while reducing the internal space to a reasonable range, thus reducing the amount of cutting fluid required for circulation. The first box section 37 is used to accommodate the horizontal conveying section 33, and the first box cover 38 is provided with a chip guide port for accommodating the discharge end of the chip guide component 35. A chip guide funnel 39 is provided between the first box section 37 and the first box cover 38 to accommodate the chips discharged from the chip guide channel as they fall into the horizontal conveying section 33.

[0047] In summary, firstly, by incorporating the chip guide 35, which features a chip guiding channel, the machine tool's chips are easily guided to one side of the machine tool, reducing the space occupied by the chip conveyor 200 at the bottom of the machine tool. This increases the distance between the support points of the machine tool base, improving the machine tool's stability. Secondly, by providing the chip guide box 36, which includes a first box section 37 and a second box section 41, the horizontal conveying section 33 of the conveyor chain can be completely enclosed, reducing the exposure and evaporation of cutting fluid and protecting the working environment. Furthermore, by providing the chip guide funnel 39, when chips are discharged from the chip guide 35, they can fall along the funnel 39 onto the horizontal conveying section 33, reducing the likelihood of chips falling onto the sides of the horizontal conveying section 33. This improves chip removal efficiency and slows down wear on the conveyor chain. In addition, by setting the first box cover 38, the first box cover 38 has a chip guide port for accommodating the discharge end of the chip guide 35, thus preventing debris from falling outside the chip guide box 36 and avoiding pollution of the site. At the same time, according to the specific setting of the chip guide 35 on the machine tool, the position of the chip guide port on the first box cover 38 can be changed accordingly, reducing changes to the first box part 37. The design changes are small and easy to implement.

[0048] In some embodiments, the first housing 38 may be provided with at least one viewing window 40 to facilitate observation of the debris situation at various locations on the horizontal conveying section 33, so as to adjust the operating speed of the conveying volume in a timely manner, increasing or decreasing the speed of chip removal. In some embodiments, a viewing window 40 may be located near the connection between the horizontal conveying section 33 and the inclined conveying section 34 to facilitate confirmation of whether there is debris accumulation. In some embodiments, a viewing window 40 may be located near the chip guide opening to prevent debris from getting stuck between the discharge end of the chip guide 35 and the first housing 38, facilitating timely detection of problems and reducing chip removal blockage. In some embodiments, the first housing 38 may be hollow, with the viewing window 40 and the chip guide opening located on opposite sides of the first housing 38, and the viewing window 40 may be inclined upwards, facilitating observation by the operator from the side of the chip conveyor 200 without being obstructed by the machine tool.

[0049] Reference Figure 8 In some embodiments, the chip guide box 36 may include a second box section 41, which is arranged in an L-shape with the first box section 37. The second box section 41 is connected to the end of the first box section 37 near the inclined conveying section 34. The second box section 41 is provided with at least one of a filter cake device 42, a decontamination device 43, and a circulation device 44. In this embodiment, the second box section 41 is provided with a filter cake device 42, a decontamination device 43, and a circulation device 44, which are arranged sequentially along the direction away from the first box section 37. In some embodiments, the filter cake device 42 may include a filter cake hopper 45, with an inlet on one side wall and a discharge filter plate on one of the remaining side walls. By providing the filter cake hopper 45, cutting fluid containing fine debris can be introduced, thereby allowing the fine debris to deposit and be collected in the filter cake hopper 45, while facilitating the cutting fluid to enter the decontamination device 43 through the discharge filter plate.

[0050] In some embodiments, the first chamber 37 may have a guide nozzle, which overlaps with the filter cake hopper 45 through the feed inlet to prevent cutting fluid containing debris from flowing out of the filter cake hopper 45. In some embodiments, the filter cake hopper 45 may be liftable for disassembly, thereby facilitating the cleaning of fine debris. In some embodiments, the filter cake hopper 45 may have an inclined wall, and the filter cake device 42 may also include a scraper 46, which is used to abut against the inclined wall to scrape the filter cake out of the filter cake hopper 45. That is, when there is a large amount of fine debris and sludge remaining in the filter cake hopper 45, the scraper 46 can be used to scrape the fine debris and sludge out along the inclined wall.

[0051] In some embodiments, the scraper 46 may include a porous scraper to separate the cutting fluid from fine debris, reducing damage to the cutting fluid and preventing fine debris from flowing with the cutting fluid and affecting scraping efficiency. In some embodiments, the scraper 46 may include a handle connected to the scraper for easy manual operation. In some embodiments, the inclined wall may have an outwardly flanged edge that overlaps the top edge of the second housing 41, facilitating the pouring out of fine debris and preventing it from adhering to the outer surface of the second housing 41. In some embodiments, the filter cake device 42 may include a low trolley to accommodate situations where fine debris is positioned low, facilitating debris collection. In some embodiments, the filter cake device 42 may also include a viewing cover 47 that covers the filter cake hopper 45, allowing for easy viewing of the debris inside the hopper 45 for timely cleaning. In some embodiments, both the filter cake hopper 45 and the viewing cover 47 may have handles for easy lifting. In some embodiments, the visible cover 47 may include a cover body and a transparent plate, simplifying manufacturing while increasing the strength of the visible cover 47.

[0052] The decontamination device 43 includes an upright decontamination disc 48, a scraping assembly 49 that holds the decontamination disc 48, and a collection tank 50 that receives the oil scraped off by the scraping assembly 49. After the cutting fluid is filtered by the filter device 42 to remove fine debris, there are fewer debris in the cutting fluid, but oil is easily retained. Therefore, driven by the motor, the decontamination disc 48 rotates continuously, causing oil to adhere to the outer surface of the decontamination disc 48. Then, when the decontamination disc 48 passes the scraping assembly 49, the two scraping blades of the scraping assembly 49 will contact the decontamination disc 48 and scrape off the oil on the decontamination disc 48. The oil will flow along or along the scraping assembly 49 into the collection tank 50.

[0053] In some embodiments, a partition plate 51 may be provided inside the sludge collection tank 50, dividing the sludge collection tank 50 into a sludge collection chamber and a return chamber. A connecting port at the bottom of the partition plate 51 connects the sludge collection chamber and the return chamber. The sludge collection chamber receives oil sludge from the scraping assembly 49, and an overflow drain 52 is provided at the top of the sludge collection chamber. An overflow return 53 is provided at the top of the return chamber, and the overflow return 53 guides the separated cutting fluid into the second tank section 41. By providing the partition plate 51, the sludge collection tank 50 has both a sludge collection chamber and a return chamber. Therefore, due to density, the oil sludge floating on the liquid surface is discharged through the overflow drain 52, while the heavier cutting fluid enters the return chamber through the bottom of the partition plate 51, facilitating its return to the second tank section 41 via the overflow return 53, thus achieving cutting fluid recycling and reducing losses. In some embodiments, the cleaning device 43 may further include a sludge collection hopper 54 for receiving oil sludge from the overflow drain 52, and the sludge collection hopper 54 is suspended on the outside of the second box section 41. By providing a suspended sludge collection hopper 54, oil sludge can be collected conveniently and quickly. At the same time, since the amount of oil sludge is small, the suspended arrangement can meet the needs and simplify the layout.

[0054] In some embodiments, the circulation device 44 may include a second cover 55, a circulation pump 56 mounted on the second cover 55, and a circulation pipeline connected to the circulation pump 56. The second cover 55 is provided with a removable feed cover 57, and a filter plate 58 that can be lifted and removed is provided on the side of the second cover 55 near the first tank 37. By providing the second cover 55, the circulation pump 56, circulation pipeline, and feed cover 57 can be installed as a whole, simplifying the layout. At the same time, the filter plate 58 can prevent some debris from entering the circulation device 44 when disassembling and cleaning the filter cake device 42 and the decontamination device 43, reducing the risk of blockage. Additionally, the feed cover 57 facilitates the addition of new cutting fluid, ensuring that the quality of the cutting fluid meets the usage requirements.

[0055] Reference Figure 1 , Figure 9 and Figure 10This invention also aims to provide an embodiment of a machine tool bed base 300. In this embodiment, the bed base 300 is a casting, primarily sand casting, to meet the requirements of the complex internal structure of the bed base 300. In some embodiments, the bed base 300 may also require outdoor placement to eliminate internal stress. In some embodiments, the bed base 300 may be machined to improve the accuracy of the mounting surface and installation, ensuring that the important dimensions of the bed base 300 meet the drawing requirements. Structurally, the base includes a left side wall 59, a right side wall 60, and a rear side wall 61. The left side wall 59 and the right side wall 60 are used to provide longitudinal guide rails, which connect the two ends of the machine tool's crossbeam. Furthermore, the base also includes a connecting wall 62 connecting the left side wall 59 and the right side wall 60. In detail, the connecting wall 62 includes an upper connecting part 63, a side connecting part 64 and a lower connecting part 65. The upper connecting part 63 is connected to the rear side wall 61, the top of the side connecting part 64 is connected to the side of the upper connecting part 63 away from the rear side wall 61, and the lower connecting part 65 is located in front of the side connecting part 64 and is connected to the bottom of the side connecting part 64.

[0056] In some embodiments, the top of the upper connecting portion 63 may be provided with a left boss 66 connecting to the left side wall 59, a right boss 67 connecting to the right side wall 60, and an intermediate channel located between the left boss 66 and the right boss 67. The left boss 66 and the right boss 67 can be used to support the middle of the crossbeam. In some embodiments, the left boss 66, the right boss 67, and the rear side wall 61 may be fitted together to form a screw structure for driving the longitudinal movement of the crossbeam, so that the crossbeam can move longitudinally with precision to meet machining requirements. In some embodiments, the left boss 66 and the rear side wall 61 may be fitted together to form an intermediate left guide rail for connecting the crossbeam. In some embodiments, the right boss 67 and the rear side wall 61 may be fitted together to form an intermediate right guide rail for connecting the crossbeam, so that multiple positions of the crossbeam are restricted, improving the accuracy of movement and load-bearing capacity.

[0057] In summary, firstly, by providing the connecting wall 62, which connects the left side wall 59 and the right side wall 60, the left side wall 59 and the right side wall 60 become a single unit, reducing the risk of relative deformation between them. Therefore, the left side wall 59 and the right side wall 60 can stably support the machine tool's crossbeam, allowing the machine tool to bear a larger load in the direction of the crossbeam's extension, thus improving machining quality. Secondly, by providing the connecting wall 62 with an upper connecting portion 63 that connects to the rear side wall 61, the machine tool can also bear a larger load in the direction perpendicular to the crossbeam, further improving overall machining quality. Furthermore, by providing a connecting wall 62 with a side connecting portion 64 and a lower connecting portion 65, the inner side of the base can be sealed, creating a relatively enclosed machining cavity that facilitates the collection of machining debris and cutting fluid, preventing dirt buildup on the floor. On the other hand, it provides space for a turntable, improving the stability of the turntable installation and facilitating multi-axis machining under complex structures, thus enhancing machining capabilities. Additionally, by providing an upper connecting portion 63, the top of which has a left boss 66 connecting to the left side wall 59, a right boss 67 connecting to the right side wall 60, and an intermediate channel between the left and right bosses 66 and 67, the left and right bosses 66 and 67 can support the middle of the crossbeam. Therefore, the left and right bosses 66 and 67 can be used to support the crossbeam, reducing slight warping caused by the spindle or vertical vibration of the spindle, improving the rigidity of the crossbeam, and enhancing machining quality. Furthermore, by setting up a central channel, it is convenient to collect and collect debris and cutting fluid from the side of the left boss 66 and right boss 67 near the rear sidewall 61, keeping them clean.

[0058] In some embodiments, the side connecting portion 64 may include a vertical wall 68 and an inclined wall 69 connecting the top of the vertical wall 68 and the upper connecting portion 63. By providing the inclined wall 69, the space occupied at the connection between the vertical wall 68 and the upper connecting portion 63 can be reduced, the risk of the machine tool spindle touching the base can be reduced, and thus, the machining space and machining range of the machine tool can be increased, thereby improving the machining capability of the machine tool. In some embodiments, the lower connecting portion 65 may include a rear inclined wall 70 connecting the side connecting portion 64, a front inclined wall opposite to the rear inclined wall 70, and a transverse discharge groove 72 connecting the bottom of the rear inclined wall 70 and the bottom of the front inclined wall. By having the lower connecting portion 65 with the front inclined wall and the rear inclined wall 70, the machining debris and the cutting fluid used for cooling can be easily collected. By providing the transverse discharge groove 72, the debris and cutting fluid can be discharged to one side of the machine tool for easy collection and separation. At the same time, it does not occupy the front space of the machine tool and does not affect the loading and unloading operation.

[0059] In some embodiments, the two ends of the transverse discharge groove 72 can be set with different heights. By setting the two ends of the transverse discharge groove 72 with different heights, the transverse discharge groove 72 is also tilted, thereby causing chips and cutting fluid to tend to be discharged to the lower end, reducing discharge resistance, and facilitating the removal of fine chips by the cutting fluid. This overcomes the problem of difficulty in clean discharge due to gaps between the discharge screw and the transverse discharge groove 72. In some embodiments, the left side wall 59 can have a left step 73, and the right side wall 60 can have a right step 74. The left step 73 supports one end of the machine tool's turntable 100, and the right step 74 supports the other end of the machine tool's turntable 100. The thickness of the left side wall 59 is less than the thickness of the right side wall 60. By making the thickness of the left side wall 59 less than the thickness of the right side wall 60, the thickness of the left side wall 59 and the thickness of the right side wall 60 are matched with the mounting portions at both ends of the turntable 100, reducing unnecessary thickness, which reduces manufacturing costs and allows for a smaller overall size of the base, resulting in a simpler machine tool structure and a smaller footprint.

[0060] Reference Figure 11 In some embodiments, the left step 73 may have a left support surface 75 for supporting the turntable 100 and a left vertical surface 76 connecting the rear side of the left support surface 75, with a connecting rib 77 provided between the left support surface 75 and the left vertical surface 76. By providing the connecting rib 77, the connection strength between the left support surface 75 and the left vertical surface 76 can be improved, overcoming the problem of weak connection due to the small wall thickness of the left side wall 59. In some embodiments, the entity on the left side wall 59 for supporting the longitudinal guide rail may protrude relative to the left step 73. By making the entity on the left side wall 59 for supporting the longitudinal guide rail protrude relative to the left step 73, the length of the longitudinal guide rail can be increased, increasing the support range for the crossbeam. At the same time, the spindle on the crossbeam can be made closer to the other side of the turntable 100, improving the stability of the other side of the machining turntable 100. In some embodiments, the entity on the right side wall 60 for supporting the longitudinal guide rail may protrude relative to the right step 74. By making the solid on the right side wall 60 that supports the longitudinal guide rail protrude relative to the right step 74, the length of the longitudinal guide rail can be increased, the support range of the crossbeam can be increased, and at the same time, the spindle on the crossbeam can be made closer to the other side of the turntable 100, thereby improving the stability of the other side of the machining turntable 100.

[0061] In some embodiments, the base body may have a multi-layered three-dimensional frame that connects and supports the connecting wall 62. By providing a multi-layered three-dimensional frame, the connecting wall 62 can be supported, reducing deformation of the connecting wall 62. At the same time, by increasing the connection between the left side wall 59 and the right side wall 60 from top to bottom, the strength and rigidity of the base body are further improved, and material usage and casting defects are reduced. In some embodiments, the bottom of the base body has an opening, thereby reducing the solidity in the center of the bottom of the base body and facilitating casting.

[0062] In some embodiments, the bottom of the rear sidewall 61 may have a rearwardly and downwardly open side recess 78. The side recess 78 also allows the solid portion of the rear sidewall 61 to be offset towards the front of the base body, reducing the molding difficulty of the base body. In some embodiments, a slanted clearance groove may be provided on the periphery of the base body, and a mounting hole may be provided at the bottom of the slanted clearance groove for mounting a support to adjust the distance between the machine tool and the ground, preventing machine tool wobbling.

[0063] Reference Figure 1 and Figure 12 The present invention aims to provide an embodiment of a machine tool crossbeam. More specifically and in detail, the present invention aims to provide an embodiment of a moving beam base 400 for a machine tool crossbeam.

[0064] In this embodiment, the moving beam base 400 includes a beam body 79, with both ends of the beam body 79 used to connect to the longitudinal guide rails of the machine tool, thereby allowing the transversely arranged crossbeam to move longitudinally. Simultaneously, one side of the beam body 79 is provided with an upper mounting portion 80, a lower mounting portion 81, and a middle mounting portion 82. The upper mounting portion 80 is used to mount the upper guide rail connecting to the transverse traverse seat of the machine tool, the lower mounting portion 81 is used to mount the lower guide rail connecting to the transverse traverse seat of the machine tool, and the middle mounting portion 82 is used to mount the lead screw structure connecting to the transverse traverse seat of the machine tool. Therefore, the transverse traverse seat can move laterally on the beam body 79, and the transverse speed and position can be precisely adjusted through the lead screw structure to meet processing requirements. More specifically, the upper mounting portion 80 includes a first side surface 83 for mounting the upper guide rail and a first inclined surface 84 located between the first side surface 83 and the middle mounting portion 82. The top of the first inclined surface 84 is disposed away from the transverse traverse seat, and the bottom of the first inclined surface 84 is disposed close to the transverse traverse seat.

[0065] In summary, firstly, by setting the first inclined surface 84 away from the transverse support, a portion of the weight of the transverse support is distributed within the vertical projection area of ​​the beam 79. This helps to reduce the center distance between the transverse support and the beam 79, reducing the torque and meeting design and usage requirements. Secondly, by setting the first inclined surface 84, the solidity of the beam 79 is reduced. In particular, it allows for more space around the inner curve of the transverse support, facilitating a gradual transition between the two solid parts of the transverse support, improving its strength, and making it less prone to cracking. Furthermore, by setting the first side surface 83, the upper guide rail is not mounted on the top of the beam 79. Therefore, the radial dimensions of the beam 79 can be reduced, thereby minimizing the impact of the beam 79 on the machine tool's external dimensions.

[0066] To explain, the radial dimension of the machine tool in the beam 79 is equal to the stroke of the beam 79 plus the outer diameter of the beam 79. Therefore, reducing the outer diameter of the beam 79 helps to reduce the overall size of the machine tool. Particularly noticeable is the reduction of overlap between the transverse support and the beam 79 in the vertical direction, thus lowering the machine tool's height. Furthermore, by providing the first side surface 83, the beam 79 is made open over a large area in the vertical direction, facilitating casting, reducing manufacturing difficulty, and improving casting quality.

[0067] In some embodiments, the intermediate mounting portion 82 may include a mounting cavity 85 for accommodating the lead screw structure. By providing the mounting cavity 85, the lead screw structure can be concealed, reducing external contact. Simultaneously, it prevents the beam 79 from protruding outwards, bringing the transverse sliding seat and the beam 79 closer together in the horizontal direction, reducing overturning moment. Furthermore, it ensures that the force driving the transverse sliding seat is located within the beam 79, preventing the beam 79 from twisting due to movement of the transverse sliding seat. In some embodiments, the mounting cavity 85 may include an upper boss 86 and a lower boss 87. The upper boss 86 connects the side wall and bottom wall of the mounting cavity 85, and the lower boss 87 is disposed opposite to the upper boss 86, connecting the bottom wall and another side wall of the mounting cavity 85. By setting the upper boss 86 and the lower boss 87, not only can the needs of installing the lead screw structure be met, but the connection between the bottom wall and the side wall of the mounting cavity 85 is also increased, improving the connection strength and reducing the cracking caused by casting. The upper boss 86 and the lower boss 87 can also be machined to improve the installation accuracy, reduce the resistance of the transverse sliding seat movement, and reduce jamming.

[0068] In some embodiments, there may be two pairs of upper bosses 86 and lower bosses 87, which are used to mount the two ends of the lead screw structure. By providing two pairs of upper bosses 86 and lower bosses 87, the two ends of the lead screw can be connected and restricted, and space can be reserved to arrange the motor driving the lead screw structure, so that the precise movement of the lead screw structure and the transmission of the motor to the lead screw structure are separated and do not affect each other. In some embodiments, the mounting cavity 85 may have an upper edge 88, which is used to mount a lateral telescopic protective cover that covers the mounting cavity 85, the first inclined surface 84, and the first side surface 83. By providing the upper edge 88, on the one hand, the need to shield the mounting cavity 85 is met, and on the other hand, the strength of the solid around the mounting cavity 85 is improved, thereby increasing the load-bearing capacity of the crossbeam. At the same time, the upper edge 88 can be used to mount the lateral telescopic protective cover, which can prevent machining debris and coolant from corroding the guide rail and lead screw structure, and also make the lateral telescopic protective cover evenly installed, reducing the gaps on the upper and lower sides of the lateral telescopic protective cover and making leakage problems less likely.

[0069] In some embodiments, the mounting cavity 85 may have a lower edge 89, which is used to mount a grating ruler for detecting the movement position of the transverse slide. By setting the grating ruler on the lower edge 89, the movement distance and position of the transverse slide can be accurately measured and controlled, improving machining accuracy. Simultaneously, the position of the grating ruler coincides with the solid forming the mounting cavity 85, which helps to reduce the height of the beam 79, making the beam 79 compact and space-saving. In some embodiments, the beam 79 may have shoulders 90 at both ends, with the shoulders 90 being hollow and the bottom of the shoulders 90 used to connect to the longitudinal guide rail. By setting the shoulders 90, on the one hand, the length of the beam 79 can be locally shortened, reducing the space occupied on the top of the machine tool, facilitating the layout of various lines and pipes, and reducing layout difficulty; on the other hand, it satisfies the need to connect the longitudinal guide rail while reducing the solid height at the shoulders 90, minimizing the impact on the tool during installation.

[0070] In some embodiments, the beam 79 may have end openings 91 at both ends. The bottom of the end opening 91 has mounting holes for connecting longitudinal guide rails, and the top of the end opening 91 has mounting holes 92 for removing bolts or nuts from the mounting holes. By providing the end openings 91, mounting holes can be easily installed to meet installation requirements. Furthermore, the walls forming the end openings 91 extend along the length of the beam 79, improving the rigidity at both ends of the beam 79 and preventing the shoulders 90 from warping due to load. Simultaneously, the end openings 91 can be thin-walled, reducing casting defects, while the mounting holes 92 facilitate the vertical removal and installation of bolts, making it easier to apply force. Moreover, there is no need to consider the matching of bolt length with the dimensions of the end openings 91.

[0071] Reference Figure 13 In some embodiments, a second inclined surface 93 may be provided on the other side of the beam 79. The top of the second inclined surface 93 is located close to the transverse sliding seat, and the bottom of the second inclined surface 93 is located away from the transverse sliding seat. By providing the second inclined surface 93, the cross-sectional profile of the beam 79 is approximately triangular, which satisfies the torsional resistance requirement of the beam 79, facilitates the support of the transverse sliding seat, and at the same time reduces the solid volume of the beam 79, thereby reducing the casting difficulty.

[0072] Reference Figure 14In some embodiments, the other side of the beam 79 may be provided with a middle longitudinal extension 94, a left longitudinal extension 95, and a right longitudinal extension 96. The bottom of the left longitudinal extension 95 and the right longitudinal extension 96 are used to connect to the longitudinal guide rail, and the bottom of the middle longitudinal extension 94 is used to connect to the screw and nut assembly that drives the longitudinal movement of the beam 79. By providing the left longitudinal extension 95 and the right longitudinal extension 96, the mating length between the beam 79 and the longitudinal guide rail can be increased, reducing the possibility of the beam 79 twisting and overturning, and also making the beam 79 move stably during longitudinal movement, reducing swaying and machining vibration. The middle longitudinal extension 94 can increase the radial dimension of the middle part of the beam 79, improve the torsional resistance of the beam 79 when bearing the transverse slide seat, reduce vibration in commonly used machining areas, and improve the machining capacity of the machine tool. It should be noted that the left and right directions in this embodiment are indicated by the operator's left and right hands when facing the machine tool, not by the left and right directions in the accompanying drawings. In some embodiments, a left notch 97 may be provided between the left longitudinal extension 95 and the middle longitudinal extension 94. Meanwhile, in some embodiments, a right notch 98 can be provided between the right longitudinal extension 96 and the middle longitudinal extension 94. By providing the left notch 97 and the right notch 98, the solid structure of the beam 79 can be easily reduced, the hollow area within the beam 79 can be reduced, and the casting difficulty can be lowered.
