Description

A milling machine worktable and a milling machine Technical Field

[0001] This invention relates to the field of milling machines, and particularly to a milling machine worktable and a milling machine. Background Technology

[0002] A milling machine is a machine tool in which the cutting tool remains stationary while the workpiece moves to perform machining. The milling machine is equipped with a movable milling table. Before machining, the workpiece usually needs to be fixed to the milling table using a fixture. The milling table is equipped with an inverted T-shaped mounting slot, and the bottom of the fixture has a corresponding inverted T-shaped mounting part. The fixture moves within the milling table through this inverted T-shaped mounting part and can be fixed by bolts or other locking devices. The workpiece is then fixed by the fixture, and milling is performed after the workpiece is fixed.

[0003] When machining a workpiece, a lot of machining debris often flies around and easily falls into the inverted T-shaped mounting slot of the milling machine table. When disassembling the fixture, the debris in the mounting slot must be cleaned first. Otherwise, the mounting part of the fixture is easy to get stuck in the mounting slot, making it difficult to disassemble the fixture. Moreover, the mounting part is easily scratched by the debris in the mounting slot, affecting its installation accuracy. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a milling machine worktable that can prevent milling chips from entering the mounting slot of the milling machine worktable, improve fixture change efficiency, and has low improvement cost.

[0005] A milling machine with the aforementioned milling worktable is also proposed.

[0006] A milling machine table according to a first aspect of the present invention includes:

[0007] The worktable includes several mounting slots for mounting fixtures;

[0008] Two sets of tape winding assemblies are respectively set at both ends of the mounting through slot and are detachably connected to the fixture, which can cover the slot openings of all mounting through slots on the milling machine worktable.

[0009] The milling machine table according to the first aspect of the present invention has at least the following beneficial effects:

[0010] 1. After the fixture is installed into the mounting slot, the two sets of tape roll assemblies are installed at both ends of the mounting slot, and the tape rolls of the tape roll assemblies are pulled out, covering the opening of the mounting slot in a strip shape until they are connected to the fixture. When the workpiece on the fixture is milled, the milling debris will fall directly onto the strip surface after the tape roll assembly is unwound, instead of entering the mounting slot. Furthermore, during cleaning, the debris on the strip surface can be cleaned directly without having to clean the debris in the mounting slot, making cleaning more convenient and efficient.

[0011] 2. When it is necessary to replace the fixture, the tape roll assembly can be removed first, and the debris on the tape roll assembly can be removed as well. After the debris on the tape roll assembly is removed, the tape roll assembly can be replaced directly, which saves the step of cleaning the installation channel and makes the replacement more efficient.

[0012] 3. The roll assembly can be directly and detachably installed onto the milling machine table in related technologies without requiring significant modifications to the milling machine table, resulting in lower costs and a wider range of applications.

The unwound tape roll is detachably connected to the clamp via the guide shaft.

[0014] According to some embodiments of the present invention, the roll holder is provided with a mounting portion, which extends out in a direction perpendicular to the axial direction of the roll shaft. The cross-section of the mounting portion corresponds to the cross-section of the mounting through groove, and can be inserted into and engaged in the mounting through groove.

[0015] According to some embodiments of the present invention, the middle portion of the cover strip roll along the length direction of the mounting slot is higher than its two sides.

[0016] According to some embodiments of the present invention, the tape roll assembly further includes a guide member, which is fixedly connected to the roll holder. The guide member is used to receive the unwinding end of the cover tape roll after passing through the guide shaft, and the guide member is provided with a guide hole for the unwinding end to pass through.

[0017] According to some embodiments of the present invention, the tape roll assembly further includes a connecting tape roll, which is fixed to the clamp, and the covering tape roll is detachably connected to the clamp via the connecting tape roll.

[0018] According to some embodiments of the present invention, the connecting tape roll includes a fixing part and a connecting part. The fixing part is fixed to the clamp and located on the side of the connecting part away from the worktable. The connecting part is suspended. A connecting hook is provided on the side of the connecting part facing the clamp. A connecting velvet is provided on the side of the covering tape roll away from the worktable. The connecting velvet is provided at the unwinding end of the covering tape roll. The connecting hook can engage and connect with the connecting velvet.

[0019] According to some embodiments of the present invention, there are multiple mounting slots, and at least one of the mounting slots is not fitted with a clamp. The tape roll assembly also includes several side strips, which correspond to the mounting slots where the clamps are not fitted and are detachably connected to the unwound tape rolls of the two cover tape rolls to cover the mounting slots where the clamps are not fitted.

[0020] According to some embodiments of the present invention, the side strip is detachably connected to the side of the roll of the cover strip away from the worktable after unwinding.

[0021] A milling machine according to a second aspect of the present invention includes the milling machine table according to a first aspect of the present invention.

[0022] The milling machine according to the second aspect of the present invention has at least the following advantages: it can quickly clean up the chips generated during workpiece milling, the chip cleaning efficiency is higher, the fixture replacement is more convenient, and the milling machine has higher processing efficiency for milling different workpieces.

[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0036] In the description of this invention, "several" refers to one or more, and "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0037] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0038] Referring to Figures 1 to 5, a milling machine worktable according to an embodiment of the present invention includes: a worktable 100 and two sets of tape winding assemblies 300. The worktable 100 includes a plurality of mounting slots 110 for mounting fixtures 200. The two sets of tape winding assemblies 300 are respectively disposed at both ends of the mounting slots 110 and are detachably connected to the fixtures 200, and can cover the slot openings 111 of all the mounting slots 110 of the milling machine worktable 100.

[0039] It is worth understanding that after the fixture 200 is installed into the mounting slot 110, the two sets of tape roll assemblies 300 are respectively installed at both ends of the mounting slot 110, and the tape roll of the tape roll assembly 300 is pulled out, which covers the slot 111 of the mounting slot 110 in a strip shape until it is connected to the fixture 200. When the workpiece on the fixture 200 is milled, the milling debris will fall directly onto the strip surface of the tape roll assembly 300 after unwinding, and will not enter the mounting slot 110. Furthermore, when cleaning, the debris on the strip surface can be cleaned directly without cleaning the debris in the mounting slot 110, making cleaning more convenient and more efficient. When fixture 200 needs to be replaced, the roll assembly 300 can be removed first, and the debris on the roll assembly 300 can be removed as well. After the debris on the roll assembly 300 is removed, the roll assembly 300 can be replaced directly, saving the step of cleaning and installing the through slot 110, thus improving replacement efficiency. The roll assembly 300 can be directly and detachably installed onto the milling machine table 100 in related technologies without requiring significant modifications to the milling machine table 100, resulting in lower costs and a wider range of applications.

[0040] In this embodiment, the mounting slot 110 is an inverted T-shaped slot, which can be formed by two T-shaped strips arranged side by side with intervals, or it can be integrally formed. The bottom of the clamp 200 is provided with an inverted T-shaped mounting part 311 installed in the mounting slot 110, which is locked by fasteners such as bolts.

[0041] It is worth noting that this solution is more suitable for situations where the workpiece is placed alone within the fixture 200. Specifically, the bottom of the fixture 200 can be fixed within the mounting slot 110, and the top of the fixture 200 can have a clamping cavity for holding the workpiece separately. When the workpiece is placed on the worktable 100 and fixed alone by the fixture 200, the workpiece itself will cover the slot 111 of the mounting slot 110 on the worktable 100. If there is no machining requirement on the side of the workpiece, the tape coil assembly 300 can be directly and detachably connected to the side of the workpiece.

[0042] Referring to Figures 1 and 3, the tape roll assembly 300 includes a roll holder 310, a roll 320, a guide shaft 330, a tensioner 340, and a cover roll 350. The roll holder 310 is installed at the end of the mounting slot 110. The roll 320 is rotatably mounted on the roll holder 310, and the axial direction of the roll 320 is parallel to the end face of the clamp 200. The cover roll 350 is sleeved on the roll 320. The tensioner 340 is connected to the roll 320 for transmission and is used to control the tension force of the roll 320 when it is unwound. After the cover roll 350 is unwound, the tape roll is detachably connected to the clamp 200 via the guide shaft 330.

[0043] It is understandable that after the fixture 200 is installed, the roll holder 310 is installed to the end of the mounting slot 110, and then the unwinding end of the masking tape roll 350 is pulled, so that the masking tape roll 350 is stretched into a strip. The unwinding end of the masking tape roll 350 will be detachably connected to the fixture 200. The stretched masking tape roll 350 will cover all the slots 111 of the mounting slot 110, so that the slots 111 of the mounting slot 110 are covered, avoiding the influence of chips during milling.

[0044] The guide shaft 330 can rotate the unwound masking tape roll 350 so that the masking tape is parallel to and in contact with the upper surface of the worktable 100. During the rotation of the masking tape roll 350, its diameter gradually decreases, and the guide shaft 330 can also correct the direction of the masking tape roll 350, ensuring that it is unwound in a constant direction.

[0045] The tensioner 340 controls the rotation speed of the reel 320 to prevent excessive rotation speed of the reel 320 when the cover tape roll 350 is under tension, which would cause excessive stretching of the cover tape roll 350 into a strip. This facilitates control over the length of the cover tape roll 350. It is important to understand that the tensioner 340 only controls the rotation speed of the reel 320 by increasing the rotational friction; it does not itself wind the cover tape roll 350. The cover tape roll 350 can only be unwound or wound manually or by a motor connected to the reel 320.

[0046] Referring to Figures 1 and 3, the roll holder 310 is provided with a mounting part 311. The mounting part 311 extends out along the axial direction of the vertical roll 320. The cross-section of the mounting part 311 corresponds to the cross-section of the mounting through groove 110, and can be inserted into and engaged in the mounting through groove 110.

[0047] It is worth understanding that the roll holder 310 is directly inserted into the mounting slot 110 through the mounting part 311, so as to realize the detachable connection between the roll assembly 300 and the worktable 100. The connection method is direct and simple, and can be used with all milling machine worktables 100. No additional processing is required on the worktable 100, such as drilling and tapping. The method of adding it to the milling machine worktable 100 is simpler and more convenient, and can effectively adapt to milling machines in related technologies.

[0048] Specifically, the mounting slot 110 is inverted T-shaped, and the mounting part 311 is also inverted T-shaped. The mounting part 311 corresponds to the mounting slot 110, and a stop ring can be provided on the side of the mounting part 311 away from its insertion end. The stop ring is used to prevent the mounting part 311 from being inserted into the mounting slot 110 after it has been inserted a certain distance. The relative position of the tape roll assembly 300 and the mounting slot 110 is limited to avoid the tape roll 350 being covered by the tape roll assembly 300 from interfering with the worktable 100 and causing installation difficulties.

[0049] Referring to Figures 1 and 3, the middle of the cover tape roll 350 along the length of the mounting slot 110 is higher than its two sides.

[0050] Specifically, through holes may be provided on both sides of the milling machine worktable 100 along the length of its mounting through slot 110, and a chip collection chamber is provided at the bottom of the milling machine worktable 100, with the chip collection chamber connected to the through holes.

[0051] It is understandable that when the middle of the masking tape roll 350 is higher than its sides, after the debris falls onto the masking assembly, it will move from the middle of the masking tape roll 350 toward its sides under its own weight. The debris will be concentrated on both sides of the worktable 100 along the length of its mounting slot 110. When the milling machine worktable 100 is provided with a through hole, the debris can fall directly into the debris collection chamber along the through hole. The number of debris distributed on the masking assembly is less, and the cleaning efficiency of the masking tape roll 350 is higher.

[0052] It is worth understanding that a flexible metal layer is provided on the side of the masking tape roll 350 away from the worktable 100. The side of the flexible metal layer away from the masking tape roll 350 is a smooth surface. The smooth surface can reduce friction, making it easier for debris to slide off to both sides of the masking tape roll 350.

[0053] Specifically, multiple support members can be installed in the middle of the masking tape roll 350. These support members are arranged along the axial direction of the masking tape roll 350, with the middle of each support member higher than its sides, thus supporting the masking tape roll 350. Alternatively, the middle of the roll 320 can be higher than its sides. When guiding, the guide shaft 330 conforms to the shape of the masking tape roll 350. Specifically, the guide shaft 330 can be positioned with its middle higher than its sides or lower than its sides, depending on the turning direction of the masking tape roll 350. This ensures that the guide shaft 330 fits snugly against the masking tape roll 350. A steel wire rope is installed in the middle of the masking tape roll 350, extending along the length of the mounting groove 110. This results in the support force in the middle of the masking tape roll 350 being higher than the support force on its sides, while the sides naturally droop under gravity, thus ensuring the middle of the masking tape roll 350 is higher than its sides.

[0054] Referring to Figures 1 and 3, the tape roll assembly 300 also includes a guide 360, which is fixedly connected to the roll holder 310. The guide 360 ​​is used to receive the unwinding end of the cover roll 350 after passing through the guide shaft 330. The guide 360 ​​is provided with a guide hole 361 for the unwinding end to pass through.

[0055] It is understandable that the unwinding end of the masking tape roll 350 will pass through the guide shaft 330 and the guide hole 361 in sequence, so that the unwinding end is flush with the worktable 100. The shape of the guide hole 361 can also be set to be high in the middle and low on both sides. The guide hole 361 shapes the shape of the masking tape roll 350, so that the masking tape roll 350 is unwound in the shape of the guide hole 361. At the same time, when positioning the tape roll assembly 300, the relative position of the unwinding end of the masking tape roll 350 and the worktable 100 can be determined by the position of the guide 360, thereby adjusting the distance between the masking tape roll 350 and the worktable 100 so that the masking tape roll 350 can fit exactly against the worktable 100.

[0056] Referring to Figures 1, 2 and 3, the tape roll assembly 300 also includes a connecting tape roll 370, which is fixed to the clamp 200. The cover tape roll 350 is detachably connected to the clamp 200 through the connecting tape roll 370.

[0057] It is worth understanding that a connecting tape roll 370 can be set on each clamp 200. The fixing method of the connecting tape roll 370 is simple and it is located on the side of the clamp 200, which does not affect the normal use of the clamp 200. The connection between the unwinding component and the clamp 200 is realized by connecting the connecting tape roll 370 and the cover tape roll 350.

[0058] Referring to Figures 1, 2, and 3, the connecting tape roll 370 includes a fixing part 371 and a connecting part 372. The fixing part 371 is fixed to the clamp 200 and is located on the side of the connecting part 372 away from the worktable 100. The connecting part 372 is suspended. A connecting hook part 3721 is provided on the side of the connecting part 372 facing the clamp 200. A connecting velvet part 351 is provided on the side of the cover tape roll 350 away from the worktable 100. The connecting velvet part 351 is provided at the unwinding end of the cover tape roll 350. The connecting hook part 3721 can hook and connect with the connecting velvet part 351.

[0059] It is worth understanding that the connection between the connecting hook 3721 and the connecting velvet 351 is achieved by hooking the connecting hook 3721 and the connecting velvet 351. The connection method is simple to operate and easy to disassemble. Moreover, after connection, the connecting part 372 of the connecting tape roll 370 is located above the covering tape roll 350, and debris is not easy to accumulate at the connection between the connecting tape roll 370 and the covering tape roll 350.

[0060] Specifically, the connecting hook portion 3721 and the connecting velour portion 351 are the two sides of the Velcro that are attached. The fixing portion 371 can be fixed to the side wall of the clamp 200 by means of adhesive, threaded connection, magnetic attraction, etc.

[0061] Referring to FIG4, there are multiple mounting slots 110, and at least one mounting slot 110 is not fitted with a clamp 200. The tape roll assembly 300 also includes several side strips 380, which correspond to the mounting slots 110 where the clamp 200 is not fitted, and are detachably connected to the tape rolls after unwinding of the two cover tape rolls 350 to cover the mounting slots 110 where the clamp 200 is not fitted.

[0062] It is understandable that when the fixture 200 has not passed through all the mounting slots 110, at least one slot 111 of the mounting slot 110 is empty. After the two tape roll assemblies 300 are connected to the fixture 200, the slots 111 of the mounting slots 110 that the fixture 200 has not passed through will be directly exposed. The exposed slots 111 will be covered by the side tape 380, and the two sides of the side tape 380 will be connected to the cover tape rolls 350 of the two tape roll assemblies 300 to cover all the slots 111 of the mounting slots 110.

[0063] The side strip 380 includes multiple base strips. The width of the base strip can be slightly larger than the distance between the two mounting slots 110. The base strips are provided with fitting parts 381 on both sides along the length direction of the mounting slots 110. The multiple base strips are arranged side by side along the connecting line of the two mounting slots 110 and are sequentially fitted and connected. The number of base strips can be selected according to the number of exposed mounting slots 110. Generally, the number of exposed mounting slots 110 is equal to the number of base strips.

[0064] The two basebands can also be detachably connected using Velcro.

[0065] Referring to Figure 4, the side strip 380 and the side of the cover strip roll 350 away from the worktable 100 after unwinding are detachably connected.

[0066] It's understandable that the side strip 380 is positioned above the cover strip roll 350, making installation of the side strip 380 more convenient. Furthermore, it can share the connecting felt at the unwinding end of the cover strip roll 350 with the connecting strip roll 370, making manufacturing easier and connection more convenient.

[0067] It is worth understanding that the entire side of the 380 can be fitted with a hook to accommodate cover rolls 350 with different spacing.

[0068] Referring to FIG5, the milling machine according to a second aspect embodiment of the present invention includes a milling machine table according to a first aspect embodiment of the present invention.

[0069] It is understandable that the tape roll assembly 300 can quickly clean up the chips generated during workpiece milling, resulting in higher chip cleaning efficiency. Furthermore, the fixture 200 is easier to replace, making the milling machine more efficient at milling different workpieces.

[0070] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
