Description
Technical Field
[0001] This application relates to the technical field of milling machine structures, and in particular to a woodworking milling machine with a protective structure. Background Technology
[0002] A wood milling machine is a device that uses a high-speed rotating milling cutter to mill wood. It is mainly used for grooving, tenoning, and cutting shaped surfaces, and is a core production facility in a woodworking workshop. When using it, the milling cutter is adjusted to fit the workpiece to be cut, the workpiece is placed on the workpiece table, and the workpiece is manually pushed under the milling cutter to complete operations such as workpiece cutting.
[0003] In related technologies, workers manually drive the workpiece to move, which puts them close to the milling cutter, potentially causing injury and adversely affecting production safety. Utility Model Content
[0004] In order to reduce the adverse impact on production safety, this application provides a woodworking milling machine with a protective structure.
[0005] The woodworking milling machine with a protective structure provided in this application adopts the following technical solution: A woodworking milling machine with a protective structure includes a worktable and a milling cutter located in the middle of the upper part of the worktable. The worktable is provided with an adjusting component for adjusting the height of the milling cutter. A protective cover covering the outside of the milling cutter is installed on the upper part of the worktable. Both ends of the protective cover have mounting openings. A drive assembly for clamping and driving the workpiece to move is provided on one side of the protective cover.
[0006] By adopting the above technical solution, the protective cover is installed on the upper side of the workbench. At this time, the milling cutter is located in the protective cover. The height of the milling cutter can be adjusted by the adjusting component. One end of the workpiece is sent into the protective cover through the mounting port at one end of the protective cover. At this time, the drive component clamps the workpiece and drives the workpiece to move and pass through the milling cutter. Thus, while the protective cover protects the workers, the drive component replaces the manual driving of the workpiece, reducing the possibility of workers coming into contact with the milling cutter and getting injured, and reducing the adverse impact on production safety.
[0007] Optionally, the drive assembly includes a drive plate with one end inserted into the upper side of the worktable and sliding along the length of the worktable. The side of the drive plate away from the milling cutter is bent upward to a vertical position. A clamping plate is provided at the bent end of the drive plate and is slidably connected to the drive plate along the height of the worktable. A drive member is provided on the drive plate to drive the clamping plate to move. A drive rod is fixedly connected to the side of the drive plate with one bent end away from the milling cutter, passing through the protective plate and slidably connected to the protective plate.
[0008] By adopting the above technical solution, the end of the workpiece enters the protective cover through the mounting port at one end until it moves and passes through the upper side of the drive plate. The drive component drives the clamping plate to move downward until it is pressed against the upper side of the workpiece. At this time, the workpiece is mounted on the drive plate. The drive rod moves along the length of the protective cover. At this time, the drive plate drives the workpiece to move and contact the milling cutter, reducing the possibility of workers coming into contact with the milling cutter and getting injured, and reducing the adverse impact on production safety.
[0009] Optionally, the end of the clamping plate away from the milling cutter passes through the drive plate and is slidably connected to the drive plate. The drive component includes a first hydraulic cylinder fixedly connected to the bent end of the drive plate and the side away from the milling cutter. The telescopic rod of the first hydraulic cylinder is fixedly connected to the clamping plate.
[0010] By adopting the above technical solution, the end of the workpiece passes through the upper side of the drive plate. At this time, the first hydraulic cylinder drives the clamping plate to move downward until it is pressed against the upper side of the workpiece, thereby fixing the workpiece on the drive plate. This makes it easier to drive the workpiece to move and contact the milling cutter through the drive rod and drive plate, reducing the possibility of workers coming into contact with the milling cutter and reducing adverse effects on production safety.
[0011] Optionally, a mounting plate is inserted into the side of the protective cover near the drive rod and is slidably connected to the protective plate along the length of the workbench. The drive rod passes through and is slidably connected to the mounting plate. A lead screw parallel to the drive rod is threaded through and connected to the mounting plate. The end of the lead screw near the drive plate is rotatably connected to the drive plate.
[0012] By adopting the above technical solution, when operating on workpieces of different widths, the drive screw rotates and drives the drive plate to move closer to or further away from the milling cutter. At this time, the drive rod slides along the width of the worktable and is connected to the protective cover until the workpiece and the milling cutter are in the same position. This makes it easier to adjust the position of the workpiece on the worktable, facilitates the operation of workpieces of different specifications, and improves work efficiency.
[0013] Optionally, the mounting plate is provided with guide plates on both sides parallel to the side of the workbench, which are inserted into the protective cover and slidably connected to the protective cover. The width of the guide plates is smaller than the width of the mounting plate.
[0014] By adopting the above technical solution, the mounting plate limits and guides the drive plate in the length direction of the protective cover, and at this time, the guide plates on both sides of the mounting plate limit the mounting plate, reducing the possibility of the mounting plate detaching from the protective cover during the sliding process and improving the stability of the movement of the mounting plate and the drive plate.
[0015] Optionally, both sides of the lower side of the protective cover are provided with fixing plates, and the fixing plates are provided with screws whose ends are inserted into the worktable and threadedly connected to the worktable.
[0016] By adopting the above technical solution, the protective cover is installed on the worktable by inserting the end of the screw into the upper part of the worktable and connecting it with the worktable by thread. Tightening the screw disengages it from the worktable and drives the protective cover to move upward until it is removed from the worktable, which facilitates the maintenance of components such as milling cutters and improves work efficiency.
[0017] Optionally, a dust suction pipe is provided through the middle of the workbench on the side near the mounting plate.
[0018] By adopting the above technical solution, when the milling cutter divides the workpiece, some debris splashes out and accumulates in the protective cover. At this time, the debris in the protective cover is sucked out by the dust suction pipe, which facilitates the cleaning of the debris in the protective cover and improves work efficiency.
[0019] Optionally, the adjusting element includes a second hydraulic cylinder located in the worktable and driving the milling cutter to move.
[0020] By adopting the above technical solution, the second hydraulic cylinder drives the milling cutter to move along the height direction of the worktable, thereby facilitating the adjustment of the grooving position of the milling cutter on the workpiece and improving its applicability.
[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The workpiece is fed into the protective cover through the mounting port at one end of the protective cover. At this time, the workpiece is clamped by the drive component and driven to move and pass through the milling cutter. Thus, while the protective cover protects the workers, the drive component replaces manual driving of the workpiece, reducing the possibility of workers coming into contact with the milling cutter and getting injured, and reducing the adverse impact on production safety. 2. When the end of the workpiece passes through the upper side of the drive plate, the hydraulic cylinder drives the clamping plate to move downward until it presses against the upper side of the workpiece, thereby fixing the workpiece on the drive plate. This makes it easier to drive the workpiece to move through the drive rod and drive plate and pass under the milling cutter, reducing the possibility of the operator coming into contact with the milling cutter. 3. The drive screw rotates and drives the drive plate to move closer to or further away from the milling cutter. At this time, the drive rod slides along the width of the worktable and is connected to the protective cover until the workpiece and the milling cutter are in the same position. This makes it easier to adjust the position of the workpiece on the worktable, making it easier to operate workpieces of different specifications and improve work efficiency.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.
[0028] This application discloses a woodworking milling machine with a protective structure. (Refer to...) Figure 1 and Figure 2 A woodworking milling machine with a protective structure includes a worktable 1 arranged horizontally, and a milling cutter 2 that moves vertically is provided in the middle of the upper side of the worktable 1. (Refer to...) Figure 2 and Figure 3 A motor 21 is installed on the lower side of the milling cutter 2 to drive the milling cutter 2 to rotate and is located on the worktable 1. The worktable 1 is provided with an adjusting component for adjusting the height of the milling cutter 2. In this embodiment, the adjusting component is set as a vertical second hydraulic cylinder 22 located in the worktable 1. The telescopic rod of the second hydraulic cylinder 22 is upward and fixedly connected to the motor 21.
[0029] The second hydraulic cylinder 22 drives the motor 21 to move the milling cutter 2 in the vertical direction, thereby adjusting the height of the milling cutter 2. When the milling cutter 2 cuts the workpiece, the motor 21 drives the milling cutter 2 to rotate, which facilitates the milling cutter 2 to cut the workpiece.
[0030] Reference Figure 1 and Figure 2 The upper side of the worktable 1 is equipped with a protective cover 3, which is set along the upper side of the worktable 1. The lower sides of both ends of the protective cover 3 are provided with mounting ports 31, which allow the workpiece to enter through the mounting port 31 at one end and be taken out through the mounting port 31 at the other end. The side of the protective cover 3 away from the milling cutter 2 is provided with a drive assembly 4 for driving the workpiece to move. Horizontal fixing plates 32 are fixedly connected to the four corners of the lower side of the protective cover 3. The fixing plates 32 are located on both sides of the protective cover 3 and are far apart from each other. Screws 33 are inserted into the fixing plates 32. The lower ends of the screws 33 pass through the fixing plates 32 and are inserted into and threadedly connected to the upper side of the worktable 1.
[0031] The protective cover 3 is installed on the upper side of the worktable 1, and the milling cutter 2 is located inside the protective cover 3. One end of the workpiece is fed into the protective cover 3 through the mounting port 31 at one end of the protective cover 3. At this time, the drive assembly 4 clamps the workpiece and drives it to move along the length of the worktable 1. Thus, while the protective cover 3 protects the operator, the drive assembly 4 replaces manual operation of the workpiece, reducing the possibility of the operator coming into contact with the milling cutter 2 and being injured.
[0032] The protective cover 3 is installed on the worktable 1 by inserting the end of the screw 33 into the upper side of the worktable 1 and threading it onto the worktable 1. Tightening the screw 33 disengages it from the worktable 1 and drives the protective cover 3 to move upward until it is detached from the worktable 1, which facilitates the maintenance of components such as the milling cutter 2.
[0033] Reference Figure 2 and Figure 3 The drive assembly 4 includes a horizontal drive plate 41 located on the side of the baffle away from the support rod. The end of the drive plate 41 away from the baffle is bent upwards to a vertical position. A horizontal pressing plate 42 is provided at the bent end of the drive plate 41, with its end inserted into and slidably connected to the bent end of the drive plate 41. A drive member for moving the pressing plate 42 is provided on the side of the drive plate 41 away from the baffle at the bent end. In this embodiment, a vertical first hydraulic cylinder 43 is fixedly connected to the drive plate 41. The telescopic rod of the first hydraulic cylinder 43 faces the pressing plate 42 and is fixedly connected to the pressing plate 42.
[0034] A sliding groove 11 is provided on the upper side of the worktable 1, which is adapted to the moving trajectory of the drive plate 41 and is arranged along the length of the worktable 1. The horizontal end of the drive plate 41 is inserted into the sliding groove 11 and is slidably connected to the worktable 1 along the sliding groove 11. At this time, the upper side of the horizontal end of the drive plate 41 is flush with the upper side of the worktable 1, and a dust suction pipe 12 for cleaning debris in the sliding groove 11 is installed in the middle of the upper side of the worktable 1 near the sliding groove 11. The upper end of the dust suction pipe 12 is flush with the bottom of the sliding groove 11. A horizontal drive rod 44 is fixedly connected to the upper end of the drive plate 41, which is bent away from the end cutter 2, and faces away from the end cutter 2. The end of the drive rod 44 away from the drive plate 41 passes through the protective cover 3 and is slidably connected to the protective cover 3 along the length of the protective cover 3.
[0035] The workpiece end enters the protective cover 3 through the mounting port 31 at one end until it moves and passes through the upper side of the drive plate 41. The first hydraulic cylinder 43 drives the clamping plate 42 to move downward until it is pressed against the upper side of the workpiece. At this time, the workpiece is mounted on the drive plate 41. The drive rod 44 moves along the length direction of the protective cover 3. At this time, the drive plate 41 drives the workpiece to move, thereby reducing the possibility of the operator coming into contact with the milling cutter 2 without affecting the cutting operation of the workpiece.
[0036] When the milling cutter 2 cuts the workpiece, some debris splashes out and accumulates in the sliding groove 11. At this time, the debris in the protective cover 3 is sucked out by the dust suction pipe 12, which makes it easier to clean the debris in the protective cover 3.
[0037] Reference Figure 3 and Figure 4 The drive plate 41 can move along the width direction of the worktable 1 in the sliding groove 11. The end of the drive rod 44 away from the baffle is sleeved and slidably connected to a vertical mounting plate 45. The protective cover 3 has a moving hole 34 along the length direction of the protective cover 3 on the side near the mounting plate 45. The mounting plate 45 is inserted into the moving hole 34 and slidably connected to the protective cover 3.
[0038] Both sides of the mounting plate 45, which is horizontally positioned, are fixedly connected to guide plates 451, each with a width smaller than that of the mounting plate 45. The guide plates 451 are inserted into the protective cover 3 and are slidably connected to the protective cover 3 along its length. The drive plate 41 is bent at one end and rotatably connected to a horizontal lead screw 46 on its lower side away from the milling cutter 2. The end of the lead screw 46 away from the milling cutter 2 passes through the mounting plate 45 and is threadedly connected to the mounting plate 45.
[0039] When cutting workpieces of different widths, the drive screw 46 rotates and drives the drive plate 41 to move closer to or further away from the milling cutter 2. At this time, the drive rod 44 slides along the width direction of the worktable 1 and is connected to the protective cover 3 until the workpiece is close to the milling cutter 2, so as to facilitate the adjustment of the position of the workpiece on the worktable 1 and facilitate the cutting of workpieces of different specifications.
[0040] Mounting plate 45 limits and guides drive plate 41 along the length of protective cover 3. At the same time, guide plates 451 on both sides of mounting plate 45 limit mounting plate 45, reducing the possibility of mounting plate 45 detaching from protective cover 3 during sliding and improving the stability of movement of mounting plate 45 and drive plate 41.
[0041] The implementation principle of a woodworking milling machine with a protective structure in this application embodiment is as follows: one end of the workpiece is fed into the protective cover 3 through the mounting port 31 at one end of the protective cover 3. At this time, the workpiece is clamped by the drive plate 41 and the clamping plate 42 and driven to move and pass through the milling cutter 2. Thus, while the protective cover 3 protects the workers, the drive plate 41 and the clamping plate 42 replace the manual drive of the workpiece, reducing the possibility of workers coming into contact with the milling cutter 2 and getting injured.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
