Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and in particular to a roller cutter replacement structure for machine tool maintenance. Background Technology

[0002] Cylindrical milling cutters, also known as roll cutters, are commonly used in horizontal milling machines. Common models include the X6132, B1-400W universal milling machine, and X6140. When using roll cutters on these horizontal milling machines, the roll cutter is mounted on a tool holder and connected to the milling machine spindle. The disassembly and assembly of the roll cutter on these horizontal milling machines is relatively cumbersome. The tool holder needs to be pulled out of the spindle to remove the cutter, and the cutter is prone to slipping off the tool holder during this process. It is also not conducive to the proper mounting of the roll cutter and the tool holder during installation. The above process usually requires two people to operate: one person operates the tool holder to separate the tool holder from the roll cutter, and the other person supports the roll cutter to prevent it from falling off the tool holder. Utility Model Content

[0003] The purpose of this invention is to address the cumbersome process of disassembling and assembling roller cutters on horizontal milling machines in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A roller cutter replacement structure for machine tool maintenance includes a horizontal milling machine. The spindle of the horizontal milling machine is equipped with a detachable tool holder, on which a roller cutter is mounted. A movable tool holder seat is provided on the tool holder. A disassembly / assembly mechanism is located below the tool holder. The disassembly / assembly mechanism includes a lifting assembly, a worktable on which the lifting assembly is connected, a base on which the worktable is hinged, a support assembly on which the support assembly slides, and a clamping mechanism.

[0006] Preferably, the lifting assembly includes guide rods, at least two of which are arranged on the horizontal milling machine. A slider is provided on the guide rod, the slider slides relative to the guide rod, a locking device is provided between the slider and the guide rod, and the slider is hinged to the worktable.

[0007] Preferably, the locking device includes a pressure rod, which is hinged to the slider. The pressure rod is provided with a pin, and a connecting member is provided between the pressure rod and the pin. The connecting member is hinged to both the pressure rod and the pin. The pin is slidably connected to the slider, and the guide rod is provided with a plurality of pin holes.

[0008] Preferably, the support component includes a drive component, the drive component is provided with a plurality of slides, the slides slide relative to the worktable, a flip cover is hinged to the slides, the flip cover engages with the slides, and both the flip cover and the slides are provided with mounting grooves, the mounting grooves are provided with a plurality of rolling elements.

[0009] Preferably, the clamping mechanism includes a pair of clamping plates located on the slide.

[0010] Preferably, the drive assembly includes a threaded rod located on the base, the threaded rod having a pair of threads in opposite directions, the threaded rod being connected to the slide via the threads, and one end of the threaded rod having a handle.

[0011] The beneficial effects proposed by this utility model are as follows:

[0012] During the disassembly of the roller cutter, the worktable is moved close to the roller cutter via the lifting assembly. This process requires the support assembly to abut against the cutter bar. Once the worktable reaches the target position, the roller cutter is fixed by the clamping mechanism. Then, the cutter bar is disconnected from the spindle of the horizontal milling machine using tools such as a wrench. Driven by the cutter bar seat, the cutter bar disengages from the spindle of the horizontal milling machine along the axial direction. At this time, the roller cutter remains fixed under the action of the disassembly and assembly mechanism, while the cutter bar moves relative to the roller cutter until the roller cutter separates from the cutter bar. At this point, the roller cutter is fixed to the base by the clamping mechanism, reducing the risk of the roller cutter slipping during disassembly and assembly. Simultaneously, the clamping mechanism's fixation of the roller cutter also facilitates easier force application by the worker to separate the cutter bar from the roller cutter. After the roller cutter separates from the cutter bar, the worktable is moved downwards via the lifting assembly until the worktable is away from the cutter bar. Conversely, when the roller cutter is installed on the tool holder, the roller cutter is first fixed on the worktable by the clamping mechanism, then the lifting assembly is driven to move the worktable to the tool holder, so that the axis of the roller cutter is aligned with the axis of the tool holder, and then the tool holder seat is driven until the tool holder passes through the roller cutter, so that the tool holder is connected to the spindle of the horizontal milling machine.

[0013] Furthermore, since the base is hinged to the worktable, the base can be used for storage, reducing interference with the operation of the horizontal milling machine. It also allows for easy access to tools during disassembly and assembly, facilitating worker operation and saving time and costs associated with tool changes. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 8A roller cutter replacement structure for machine tool maintenance includes a horizontal milling machine 1. A detachable cutter bar 2 is mounted on the spindle of the horizontal milling machine 1. A roller cutter 3 is mounted on the cutter bar 2. A movable cutter bar seat 4 is mounted on the cutter bar 2. A disassembly and assembly mechanism is located below the cutter bar 2. The disassembly and assembly mechanism includes a lifting assembly. A worktable 5 is mounted on the lifting assembly and connected to the lifting assembly. A base 6 is mounted on the worktable 5 and hinged to the worktable 5. A support assembly is mounted on the base 6 and slides on the base 6. A clamping mechanism is mounted on the support assembly. Specifically, the horizontal milling machine 1 is preferably an X6132 series horizontal milling machine. When disassembling the roller cutter 3, the worktable 5 is moved close to the roller cutter 3 via the lifting assembly. This process requires the support assembly to abut against the tool holder 2. After the worktable 5 moves to the target position, the roller cutter 3 is fixed by the clamping mechanism. Then, the tool holder 2 is disconnected from the spindle of the horizontal milling machine 1 using a wrench or other tools. Under the drive of the tool holder seat 4, the tool holder 2 is disengaged from the spindle of the horizontal milling machine 1 along the axial direction. At this time, the roller cutter 3 remains fixed under the action of the disassembly and assembly mechanism, while the tool holder 2 moves relative to the roller cutter 3 until the roller cutter 3 separates from the tool holder 2. At this time, the roller cutter 3 is fixed on the base 6 by the clamping mechanism, reducing the risk of the roller cutter 3 slipping during disassembly and assembly. At the same time, the clamping and fixing of the roller cutter 3 by the clamping mechanism also makes it easier for the worker to apply force to drive the tool holder 2 to separate from the roller cutter 3. After the roller cutter 3 separates from the tool holder 2, the lifting assembly moves the worktable 5 downward until it moves away from the tool holder 2. Conversely, when the roller cutter 3 is mounted on the tool holder 2, the roller cutter 3 is first fixed to the worktable 5 by the clamping mechanism, then the lifting assembly is driven to move the worktable 5 to the tool holder 2, aligning the axis of the roller cutter 3 with the axis of the tool holder 2. Then the tool holder 4 is driven until the tool holder 2 passes through the roller cutter 3, connecting the tool holder 2 to the spindle of the horizontal milling machine 1.

[0025] Furthermore, since the base 6 is hinged to the worktable 5, the base 6 can realize a storage function, reducing interference with the operation of the horizontal milling machine 1. It also enables the tool to be disassembled and retrieved at any time, which is convenient for workers to operate and saves the cost of tool changing time.

[0026] Specifically, the lifting assembly includes guide rods 7, with at least two guide rods 7 arranged on the horizontal milling machine 1. A slider 8 is provided on each guide rod 7, sliding relative to the guide rod 7. A locking device is provided between the slider 8 and the guide rod 7, and the slider 8 is hinged to the worktable 5. The slider 8 slides up and down on the guide rods 7, driving the worktable 5 to move on the horizontal milling machine 1, allowing the worktable 5 to move away from or closer to the tool holder 2. This facilitates tool assembly and disassembly, and allows for convenient storage without affecting the normal operation of the horizontal milling machine 1 after tool changing.

[0027] Specifically, the locking device includes a pressure rod 9, which is hinged to the slider 8. A pin 15 is provided on the pressure rod 9, and a connecting member 16 is provided between the pressure rod 9 and the pin 15. The connecting member 16 is hinged to both the pressure rod 9 and the pin 15. The pin 15 is slidably connected to the slider 8. A plurality of pin holes 17 are provided on the guide rod 7. The locking device is used to fix the worktable 5 at a target height. Specifically, the worker drives the pressure rod 9, causing the pin 15 to separate from the pin holes 17, thereby releasing the slider 8 from the guide rod 7. The slider 8 can then slide on the guide rod 7. When the worktable 5 is at the target height, force is applied to the pressure rod 9, causing the pin 15 to pass through the pin holes 17, thus fixing the slider 8 to the guide rod 7. In the above process, the pressure rod 9 and the pin 15 are connected by the connector 16. The connector 16 is hinged to both the pressure rod 9 and the pin 15, thereby improving the flexibility of the pressure rod 9 in driving the pin 15 and reducing the risk of interference and jamming when the pressure rod 9 drives the pin 15.

[0028] Specifically, the support assembly includes a drive assembly, which has several slides 10 that slide relative to the worktable 5. A hinged cover 11 is hinged to each slide 10 and engages with it. Both the hinged cover 11 and the slide 10 have mounting grooves 13, each containing several rolling elements 12. When the slide 10 abuts against the cutter bar 2, the rolling elements 12 contact the surface of the cutter bar 2. Then, the hinged cover 11 flips and engages with the slide 10, thus clamping the cutter bar 2 between the hinged cover 11 and the slide 10. Preferably, there are two slides 10 on the worktable 5. During the disassembly of the cutter bar 2, the cutter bar 2 slides relative to the slides 10 under the drive of the cutter bar seat 4 and through the rolling elements 12, which helps maintain stability during the separation of the cutter bar 2 from the roller cutter 3. The sliding of the slide table 10 described above is driven by the drive assembly, which further improves the stability of the slide table 10 during displacement.

[0029] Specifically, the clamping mechanism includes a pair of clamping plates 20 located on the side of the slide table 10, and each clamping plate 20 has a flexible block. The clamping plates 20 are fixedly connected to the slide table 10. When the slide table 10 moves under the drive of the drive assembly, the clamping plates 20 move with the slide table 10 until the roller cutter 3 is clamped. To reduce damage to the surface of the roller cutter 3 during clamping, a flexible block is provided on the clamping surface of the clamping plates 20. The flexible block is preferably made of rubber, which has good wear resistance and elasticity, thus improving friction during clamping and reducing wear on the surface of the roller cutter 3.

[0030] Specifically, the drive assembly includes a threaded rod 18 located on the base 6. The threaded rod 18 has a pair of oppositely oriented threads 21. The threaded rod 18 is connected to the slide table 10 via the threads 21. One end of the threaded rod 18 has a handle 19. When a worker drives the handle 19 to rotate, the threaded rod 18 rotates synchronously. During this process, the slider 8 moves linearly along the axis of the threaded rod 18. Because the threads 21 are arranged in opposite directions on the threaded rod 18, when the threaded rod 18 rotates, the slide tables 10 move simultaneously in opposite directions, thereby driving the clamping plate 20 to clamp or release the roller cutter 3 through the movement of the slide tables 10.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
