Description

Technical Field

[0001] This invention relates to the field of milling grooves on the side panels of sauna furnaces, specifically to a milling groove device for the side panels of sauna furnaces. Background Technology

[0002] Sauna rooms, as a common leisure and wellness facility, rely on a sauna heater as their core heating component. A sauna heater typically consists of a metal outer shell, internal heating elements, and a temperature control system. The side panels of the heater body are a crucial part of the outer shell, serving multiple functions including structural support, heat dissipation and ventilation, and safety protection. For milling grooves on the metal side panels of sauna heaters, some manufacturers use general-purpose vertical CNC milling machines. These machines have a basic structure with a vertical spindle layout and a worktable that can move along the X, Y, and Z axes, enabling drilling, milling grooves, and contour machining of flat parts.

[0003] However, currently practical CNC milling machines are usually inconvenient to change tools, while CNC milling machines with tool magazines that can automatically change tools occupy a relatively large space. The tool magazine and clamping structure during the tool changing process are relatively precise, resulting in higher production and maintenance costs. Furthermore, it is inconvenient to clean the tool head after replacement, affecting reuse. In addition, existing small CNC milling machines are usually inconvenient to adjust the angle of the milling cutter, which greatly limits the processing. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides the following technical solution: a milling device for the side plate of a sauna furnace, comprising: The workbench has legs and a table surface. A positioning fixture is fixedly connected to the table surface. A diagonal brace is fixedly connected to the top of the workbench on one side of the positioning fixture. Tool magazines are fixedly connected to the top of the workbench on both sides of the diagonal brace. A fixed crossbeam has an I-beam structure and a diagonal brace fixed to the bottom of the fixed crossbeam. One end of the fixed crossbeam is fixedly connected to the diagonal brace bracket, and the end of the diagonal brace away from the fixed crossbeam is fixedly connected to the diagonal brace bracket. A cross guide rail is fixedly connected to the bottom of the fixed crossbeam. A suspension bracket with a lifting structure, wherein the fixed end of the suspension bracket is fixedly connected to a slider inside a cross guide rail, the movable end of the suspension bracket is fixedly connected to a fixed part of a rotating device, the movable part of the rotating device is fixedly connected to a fixed part of a tool holder, and a drive motor is fixedly connected to the top of the fixed part of the tool holder. The rotating device includes: A rotating disk has a circular disk-shaped structure and through holes on both sides of the circular disk-shaped structure. A rotating motor is fixedly connected to one side of the rotating disk, and the top of the rotating disk is fixedly connected to the movable end of the suspension bracket. A rotating rod is installed inside the rotating disk. Both ends of the rotating rod extend to the outside of the rotating disk through through holes on both sides of the rotating disk. One end of the rotating rod is fixedly connected to the drive shaft of the rotating motor, and the end of the rotating rod away from the rotating motor is fixedly connected to the fixing part of the tool holder. The limiting plate has a fan-shaped structure and is set inside the rotating disk. One side of the limiting plate is fixedly connected to the rotating rod, and both sides of the limiting plate are fixedly connected to support wheels. It can limit the rotation of the rotating rod during rotation, so as to avoid the rotating rod from deflecting and causing inaccurate tilt angle. At the same time, the support wheels reduce mechanical wear, so that high accuracy can be guaranteed even after long-term use.

[0005] Preferably, the rotating device further includes: The limiting slide is arc-shaped, and its side is fixedly connected to the side of the movable end of the suspension bracket. The bottom of the limiting slide is fixedly connected to the rotating disk through the bracket. An arc-shaped locking tooth is provided inside the limiting slide. A telescopic push rod is fixedly connected to the top of the arc-shaped locking tooth. The fixed part of the telescopic push rod passes through the limiting slide and is fixedly connected to the limiting slide. The sliding rack has the same arc-shaped structure as the limiting slide. The top of the sliding rack has meshing teeth that are adapted to the arc-shaped locking teeth. By cooperating with the arc-shaped locking teeth, the angle of the milling cutter can be fixed at a certain position, and the torque generated during the milling process can be borne by the milling cutter. This avoids the torque being transmitted to the motor and causing damage to the motor. At the same time, it can also reduce the requirements of the equipment on the motor. The sliding rack is set inside the limiting slide and is slidably connected to the inner wall of the limiting slide. A connecting block, one side of which is fixedly connected to the sliding rack, and the side of the connecting block away from the sliding rack extends to the outside of the limiting slide and is fixedly connected to the fixing part of the tool holder.

[0006] Preferably, the tool magazine includes a fixed bracket, a positioning plate fixedly connected to the top of the fixed bracket, a mounting slide rail fixedly connected to one side of the positioning plate, a mounting base fixedly connected to the top of the electronic slider inside the mounting slide rail, a mounting chuck fixedly connected to one side of the mounting base, a switching slide rail fixedly connected to the side of the positioning plate away from the mounting slide rail, a storage bracket fixedly connected to the side of the electronic slider inside the switching slide rail, a storage chuck fixedly connected to the inner wall of the storage bracket, a tool fixedly connected to the inner wall of the storage chuck, a cleaning component fixedly connected to the side of the fixed bracket, and the bottom of the fixed bracket fixedly connected to the worktable. A through hole adapted to the mounting chuck is provided on the positioning plate.

[0007] Preferably, the mounting chuck includes a first chuck seat, one side of which is fixedly connected to a mounting base, and a first clamping piece is fixedly connected to the side of the first chuck seat away from the mounting base. The first clamping piece is arc-shaped and made of elastic metal. Two sets of the first clamping pieces are provided and symmetrically distributed on the side of the first chuck seat. The cutting tool has an annular groove adapted to the first clamping piece.

[0008] Preferably, the storage chuck includes a second chuck seat, one side of which is fixedly connected to the storage bracket. A travel hole is provided at the center of the second chuck seat. A second clamping plate is fixedly connected to the side of the second chuck seat away from the storage bracket. The second clamping plate is arc-shaped and made of elastic metal. There are four sets of the second clamping plates, which are evenly distributed around the travel hole. The cutting tool has an annular groove that matches the second clamping plate. The design of the storage chuck and the mounting chuck can simplify the clamping structure and reduce the cost of use and maintenance.

[0009] Preferably, the cleaning assembly includes a lifting platform, a positioning seat fixedly connected to the top of the lifting platform, a water tank fixedly connected to the top of the positioning seat, an electric push rod fixedly connected to one side of the water tank, a fixed ring fixedly connected to the end of the electric push rod away from the water tank, a rotating ring rotatably connected to the inner wall of the fixed ring, and a cleaning brush fixedly connected to the inner wall of the rotating ring. By wrapping the blade with the rotating ring and the cleaning brush, cleaning dead corners can be avoided, and the cleaning of the blade can be more comprehensive. A small motor is fixedly connected to the bottom of the fixed ring through a bracket, and the drive shaft of the small motor is fixedly connected to the rotating ring through the bracket. The water tank contains a water pump, and the water outlet of the water pump inside the water tank is connected to a drain pipe. The end of the drain pipe away from the water tank extends to the top of the fixed ring and is fixedly connected to the fixed ring.

[0010] Preferably, the side of the lifting platform is fixedly connected to the fixed bracket, the bottom of the fixed ring is fixedly connected to a conical baffle through the bracket, the drive shaft of the small motor passes through the conical baffle and is rotatably connected to the conical baffle, the top of the water tank is also fixedly connected to a fan, the air outlet of the fan is connected to an air duct, the end of the air duct away from the fan extends to the top of the fixed ring, and the bottom of the air duct is fixedly connected to the fixed ring through the bracket.

[0011] It has the following beneficial effects: 1. The sauna room furnace side panel milling equipment uses a rotating motor to drive a rotating rod, which in turn drives a tool holder to rotate. The tool holder then drives the milling cutter inside to rotate, allowing the milling cutter to be set at an angle for easy machining of the inclined surface and milling out the inclined groove.

[0012] 2. In this sauna room furnace side plate milling equipment, the sliding rack is connected to the tool holder through a connecting block. During the rotation of the tool holder, the sliding rack can be driven to rotate. When the tool holder rotates to the required tilt angle, the telescopic push rod drives the arc-shaped locking tooth to move, and the arc-shaped locking tooth engages with the sliding rack, thus fixing the sliding rack. This restricts the tool holder through the sliding rack, making the tool holder more stable. It also prevents the torque generated during the milling process from being transmitted to the rotating motor, which helps protect the motor. In addition, it also reduces the requirements of the motor and lowers the cost of use and maintenance.

[0013] 3. This sauna room furnace side plate milling equipment features a symmetrical tool magazine design, which makes full use of the remaining space of the equipment and reduces the space occupied by the device. At the same time, the movable storage bracket and mounting base work together to realize the tool changing operation. The stored tools can be moved to a position that does not affect the processing. When changing tools, simply move the required tool to the tool changing station, and move it back after the tool change is completed. This can make fuller use of the remaining space of the equipment. The tool is clamped by the installation of the chuck and the first and second clamping plates inside the storage chuck. The clamping structure is simple. The release and clamping only require the resistance and thrust provided by the equipment itself. No clamping power is required, and no additional robotic arm is required for clamping and transfer. The use and maintenance costs are low.

[0014] 4. The sauna room furnace side plate milling equipment facilitates the cleaning of replaced cutting tools. After cleaning, the lifting platform drives the fixed ring to descend. When the cutting tool comes out of the rotating ring, it is quickly dried by the fan and air duct. The cleaning structure prevents residual chips on the cutting head from affecting the tool's next use. The rotating ring and cleaning brush allow the brush to directly contact the tool surface for cleaning, resulting in a good cleaning effect. The design of the rotating ring and cleaning brush completely encloses the tool, and the rotation action facilitates comprehensive cleaning without creating cleaning dead spots.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] For the first embodiment, please refer to... Figures 1-4This invention provides a technical solution: When milling grooves in a metal plate, the metal plate to be processed is placed on the positioning fixture 2 on the top of the worktable 1, and the metal plate is fixed by the positioning fixture 2. Then, the tool holder 9 is lowered by the suspension bracket 7, and at the same time, the drive motor 10 drives the milling cutter inside the tool holder 9 to rotate, thus milling grooves in the metal plate. When it is necessary to adjust the angle of the milling cutter, the rotating motor 82 drives the rotating rod 83 to rotate, the rotating rod 83 drives the tool holder 9 to rotate, and the tool holder 9 drives the milling cutter inside it to rotate, so that the milling cutter can be set at an angle, which is convenient for processing the inclined surface, and can also mill the inclined surface. The slot is formed by connecting the sliding rack 80 to the tool holder 9 via the connecting block 89. During the rotation of the tool holder 9, the sliding rack 80 can be driven to rotate. When the tool holder 9 rotates to the required tilt angle, the telescopic push rod 88 drives the arc-shaped retaining tooth 87 to move, engaging the arc-shaped retaining tooth 87 with the sliding rack 80, thus fixing the sliding rack 80. This restricts the tool holder 9 through the sliding rack 80, making the tool holder 9 more stable. It also prevents the torque generated during the milling process from being transmitted to the rotating motor 82, thus protecting the motor and reducing the requirements of the equipment on the motor, thereby reducing the cost of use and maintenance.

[0019] Second embodiment, please refer to Figures 1-9 This invention provides a technical solution: When a tool change is required, the cross guide rail 6 and the suspension bracket 7 work together to move the tool holder 9 to the tool change station. Then, the electronic slider inside the mounting slide rail 43 moves the mounting base 44 and the mounting chuck 45. The mounting base 44 moves the mounting chuck 45 through the travel hole 482 inside the storage bracket 47 and the storage chuck 48. When the mounting chuck 45 moves to the side of the tool 49 inside the tool holder 9, it continues to move. The tool 49 uses the squeezing force to open the first clamping plate 452 inside the mounting chuck 45 and slides into the first clamping plate 452. As the first clamping plate 452 is opened, it slides into the annular groove on the tool 49. When the tool 49 is completely inside the first clamping plate 452, it can pass through the first clamping plate 452. 2. Clamp the tool 49, and then use the electronic slider inside the mounting slide rail 43 to drive the mounting chuck 45 holding the tool 49 back. When the mounting chuck 45 moves to the position of the storage bracket 47, it continues to move and causes the tool 49 to be squeezed into the second clamping plate 483 inside the storage chuck 48. The tool 49 can be clamped by the second clamping plate 483. Then the mounting chuck 45 exits from the stroke hole 482. At this time, the electronic slider inside the switching slide rail 46 drives the storage bracket 47 to slide. The storage bracket 47 drives the storage chuck 48 to move. The storage chuck 48 moves the appropriate tool 49 to the position facing the mounting chuck 45. The tool 49 can be moved to the tool holder 9 for replacement by moving the mounting chuck 45. The symmetrical tool magazine 4 design makes full use of the remaining space of the equipment, which can reduce the space occupied by the device. At the same time, the movable storage bracket 47 and the mounting base 44 work together to realize the tool changing operation. The stored tools can be moved to a position that does not affect the processing. When changing tools, the required tools are simply moved to the tool changing station, and after the tool change is completed, they can be moved back. This can make fuller use of the remaining space of the equipment. The tools are clamped by the first clamping plate 452 and the second clamping plate 483 inside the mounting chuck 45 and the storage chuck 48. The clamping structure is simple. The release and clamping only need to be achieved by the resistance and thrust provided by the equipment itself. No clamping power is required, and no additional robotic arm is required for clamping and transfer. The use and maintenance costs are low. After the tool change is completed, the storage bracket 47 is moved by the switching slide rail 46. The storage bracket 47 moves the removed tool 49 to the cleaning station via the storage chuck 48. Then, the electric push rod 404 moves the fixing ring 405 and the rotating ring 406 inside the fixing ring 405 directly below the tool 49. The lifting platform 401 moves the water tank 403 upward, which in turn moves the fixing ring 405 and the rotating ring 406 upward until the tool 49 is inserted into the cleaning brush 407 inside the rotating ring 406. Then, the small motor 408 is started, which drives the rotating ring 406 to rotate. The rotating ring 406 drives the cleaning brush 407 to rotate. At the same time, the water pump inside the water tank 403 sprays the cleaning solution onto the tool 49 inside the rotating ring 406 through the drain pipe 409. The tool 49 can be cleaned by the cleaning brush 407, making it convenient to clean the replaced tool 49. After cleaning, the lifting platform 401 drives the fixing ring 405 to descend. When the tool 49 comes out of the rotating ring 406, the fan 411 and air duct 412 quickly dry the tool 49. The cleaning structure can prevent residual chips on the tool head from affecting the next use of the tool 49. The rotating ring 406 and cleaning brush 407 are set up so that the cleaning brush 407 can directly contact the tool 49 to clean the tool surface, and the cleaning effect is good. At the same time, the structural design of the rotating ring 406 and cleaning brush 407 can completely wrap the tool 49. With the rotation action, it is convenient to clean the tool 49 thoroughly and avoid cleaning dead corners.

[0020] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
