[0001] The present invention relates to the technical field of milling processing, in particular to a processing center for milling waveguide structural parts. Background Art

[0002] High-signal waveguide structural parts, waveguide is a closed structure that can transmit electromagnetic waves, usually formed by a cavity between two parallel metal plates. Waveguide can transmit high-frequency electromagnetic signals within a certain range and is widely used in wireless communications, radar, and microwave ovens.

[0006] By adopting the above technical solution, the user can rotate the first threaded rod by turning the knob, so that the movable plate and the clamping member move on the second slide rod, thereby flexibly adjusting the clamping position and force according to workpieces of different sizes, solving the problem of processing deviation caused by unstable clamping during processing of waveguide structural parts.

[0007] Preferably, the locking assembly includes a plurality of fifth sliding rods, and the plurality of fifth sliding rods are fixedly connected to the back plate. There are connecting pieces slidably connected between the plurality of fifth sliding rods, and the connecting pieces are fixedly connected to a plurality of limit blocks on the side close to the movable seat.

[0008] Preferably, the opening and closing assembly includes multiple connecting plates, multiple connecting plates are slidingly connected to the back plate, multiple connecting plates are fixedly connected to a sliding plate on one side, multiple connecting plates are rotatably connected to a roller on the other side, and multiple connecting plates are fixedly connected to a second spring between the back plate.

[0009] Preferably, a plurality of fourth sliding rods are fixedly connected to the rear side of the back panel, a moving part is slidably connected between the plurality of fourth sliding rods, the moving part is located at the top of the moving frame, a plurality of first springs are fixedly connected to the top of the moving part, and the ends of the plurality of first springs away from the moving part are fixedly connected to adjacent fourth sliding rods.

[0010] Preferably, a sliding groove is provided on the surface of the connecting member, a fixed column is slidably connected inside the sliding groove, and the fixed column is fixedly connected to the movable frame.

[0011] Preferably, the top of the base is fixedly connected to a shell, a plurality of first sliding rods are fixedly connected between the left and right sides of the inner wall of the shell, and the plurality of first sliding rods are all slidably connected to the sliding plate.

[0012] Preferably, a plurality of second sliding bars are fixedly connected to one side of the movable seat, and the plurality of second sliding bars are all slidably connected to adjacent clamping members.

[0013] Preferably, a water tank is fixedly connected to the top of the mobile frame, a water pump is provided on one side of the water tank, the water pump input end is fixedly arranged between the water tank, a delivery pipe is fixedly provided at the output end of the water pump, the delivery pipe is fixedly connected to the mobile frame, and a plurality of nozzles are fixedly connected to the surface of the delivery pipe.

[0014] Preferably, a plurality of fixed blocks are fixedly connected to the side of the movable seat away from the first threaded rod, and the plurality of fixed blocks penetrate and extend into the interior of the back plate, and the plurality of fixed blocks are all slidably connected to the back plate.

[0015] Preferably, the rear side of the movable frame passes through and extends into the interior of the connecting member, and the movable frame and the connecting member are slidably connected.

[0016] Working Principle: When the user needs to process a waveguide structure, the waveguide structure body is placed on the top of the movable base, the angle of the clamp is adjusted, and the knob is turned. The knob drives the first threaded rod to rotate, and the first threaded rod drives the movable plate and the clamp to slide on the second slide rod, thereby fixing the waveguide structure body on the movable base. The starting motor drives the second threaded rod to rotate, so that the movable frame and the milling mechanism are lowered to the processing position. At the same time, the fixed column fixedly connected to the movable frame slides in the slide groove of the connecting piece. Due to the guiding effect of the slide groove, the connecting piece is pushed to move along the fifth slide rod, so that the limit block is stuck with the fixed block of the movable seat, and the movable seat is automatically locked to prevent sliding during processing. At this time, the sliding plate is closed under the action of the second spring. During the processing, the water tank descends with the movable frame, and the water pump draws coolant through the delivery pipe and the nozzle to spray it to the processing part to play a cooling and lubricating role. When milling is completed, the motor reverses and drives the second threaded rod to rotate in the opposite direction. When the movable frame rises, it lifts up the movable part, and the movable part overcomes the elastic force of the first spring and moves up along the fourth slide rod, pressing the roller so that the connecting plate drives the sliding plate to open to both sides. At the same time, the fixed column slides in the slide groove, and the connecting part resets to drive the limit block to disengage from the fixed block, and the movable seat is unlocked. At this time, the user can remove the processed workpiece, realizing the full process automation operation from workpiece clamping, processing to picking up, ensuring processing accuracy and safety, and improving production efficiency.

[0017] The present invention provides a machining center for milling waveguide structural parts. It has the following beneficial effects: 1. In the present invention, the first threaded rod is rotated by turning the knob, thereby driving the movable plate and the clamping member to move on the second slide rod. The waveguide structure body is fixed by moving the clamping member forward, thereby realizing rapid clamping of the workpiece. The clamping position and force can be flexibly adjusted according to workpieces of different sizes, solving the problems in the prior art of cumbersome workpiece clamping operation, difficulty in quickly adapting to workpieces of different specifications, and insufficient clamping stability that easily leads to workpiece displacement during processing.

[0018] 2. In the present invention, the second threaded rod is driven to rotate by the motor, thereby driving the movable frame and the milling mechanism to descend to perform milling processing on the waveguide structural component body. When the movable frame descends, the fixed column moves downward synchronously. Since the fixed column slides in the slide groove, the connecting member and the limit block move forward. At this time, the limit block clamps the fixed block to fix the movable seat, thereby realizing automatic locking of the movable seat during milling processing, preventing it from sliding left and right, ensuring the stability of the workpiece position during milling processing, and ensuring processing accuracy.

[0019] 3. In the present invention, the motor drives the second threaded rod to rotate in the opposite direction at the end of milling, so that the movable frame is raised. During the raising process of the movable frame, the movable part is lifted up. At this time, the movable part presses against the roller, so that the roller, the connecting plate and the sliding plate move to both sides, thereby opening the two sliding plates. The sliding plates are automatically opened at the end of the milling process. During the processing, the movable frame descends, and the sliding plates are automatically closed to ensure the processing safety and protection. After the processing is completed, the cabinet door is automatically opened after the movable frame is lifted to facilitate the workpiece removal and equipment maintenance.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] Please see the attached Figure 1 -Attached Figure 3, an embodiment of the present invention provides a machining center for milling waveguide structural parts, including a base 1, a back plate 3 is fixedly connected to one side of the base 1, a third slide rod 23 is fixedly connected to the side of the back plate 3 close to the base 1, a movable seat 6 is slidably connected to the surface of the third slide rod 23, a first threaded rod 7 is rotatably connected to one side of the movable seat 6, a movable plate 9 is threadedly connected to the surface of the first threaded rod 7, a plurality of clamping members 10 are rotatably connected to the surface of the movable plate 9, a knob 8 is fixedly connected to the end of the first threaded rod 7 away from the movable seat 6, a waveguide structural part body 12 is arranged on the top of the movable seat 6, a motor 13 is fixedly connected to the top of the back plate 3, a second threaded rod 14 is fixedly arranged on the output end of the motor 13, a movable frame 15 is threadedly connected to the surface of the second threaded rod 14, a milling mechanism 22 is fixedly connected to the bottom of the movable frame 15, a locking component is arranged on the rear side of the back plate 3, and an opening and closing component is arranged on the front side of the back plate 3.

[0024] Specifically, the user places the waveguide structure body 12 on the top of the movable seat 6, adjusts the clamping member 10 to the required angle, and then turns the knob 8 to drive the first threaded rod 7 to rotate. When the first threaded rod 7 rotates, it drives the movable plate 9 and the clamping member 10 to move forward. At this time, the clamping member 10 fixes the waveguide structure body 12, and the clamping position can be flexibly adjusted according to the size of the workpiece. Then, the motor 13 is started to drive the second threaded rod 14 to rotate, driving the movable frame 15 and the milling mechanism 22 fixed at the bottom thereof to descend to perform milling processing on the waveguide structure body 12.

[0025] See attached Figure 5 and attached Figure 6 The locking assembly includes multiple fifth sliding rods 29, and the multiple fifth sliding rods 29 are fixedly connected to the back plate 3. There are connecting members 30 slidingly connected between the multiple fifth sliding rods 29, and the connecting members 30 are fixedly connected to multiple limit blocks 32 on the side close to the movable seat 6.

[0026] Specifically, when the user starts the motor 13 to drive the second threaded rod 14 to rotate, and when the movable frame 15 and the milling mechanism 22 descend for milling processing, the fixed column 21 will move downward synchronously with the movable frame 15. Since the fixed column 21 slides in the slide groove 31, the connecting member 30 can slide along the fifth slide bar 29, and the connecting member 30 and multiple limit blocks 32 move in the direction close to the movable seat 6 until the limit block 32 is stuck on the fixed block 20 on the movable seat 6, thereby fixing the movable seat 6 and preventing the movable seat 6 from sliding left and right during the milling process. Automatic locking of the movable seat 6 is achieved at the beginning of the milling process, ensuring the stability of the workpiece position during the processing and improving the accuracy of the milling process. At the end of the processing, the movable frame 15 is lifted, and the limit block 32 is now separated from the fixed block 20, and the movable seat 6 can slide freely to adjust its position, which simplifies the operation process and reduces the risk of processing errors or safety accidents.

[0027] See attached Figure 5and attached Figure 7 The opening and closing assembly includes multiple connecting plates 24, which are all slidably connected to the back plate 3. One side of the multiple connecting plates 24 is fixedly connected to the sliding plate 5, and the other side of the multiple connecting plates 24 is rotatably connected to the roller 25. A second spring 33 is fixedly connected between the multiple connecting plates 24 and the back plate 3.

[0028] The second spring 33 is engaged to move the sliding plate 5 to the left and right sides of the movable frame 15, thereby preventing the sliding plate 5 from being pulled out of the movable frame 15.

[0029] See attached Figure 7 and attached Figure 8 A plurality of fourth slide bars 26 are fixedly connected to the rear side of the back plate 3, and a moving member 28 is slidably connected between the plurality of fourth slide bars 26. The moving member 28 is located at the top of the moving frame 15, and a plurality of first springs 27 are fixedly connected to the top of the moving member 28. The ends of the plurality of first springs 27 away from the moving member 28 are fixedly connected to the adjacent fourth slide bars 26.

[0030] Specifically, the motor 13 drives the second threaded rod 14 to rotate, driving the movable frame 15 to descend. At this time, the top of the movable frame 15 does not contact the movable part 28, and the movable part 28 is kept at the bottom of the fourth slide bar 26 under the elastic force of multiple first springs 27. When milling is completed, the motor 13 drives the second threaded rod 14 to rotate in the opposite direction to make the movable frame 15 rise. The top of the movable frame 15 gradually pushes up the movable part 28, and the movable part 28 overcomes the elastic force of the first spring 27 and slides upward along the fourth slide bar 26. After the movable part 28 moves upward, it presses against the roller 25, and then pushes the connecting plate 24 and the sliding plate 5 to move to both sides to realize opening, realizing the function of automatic opening of the sliding plate 5 after milling is completed, without the need for a complex control system, reducing equipment cost, and at the same time, the first spring 27 can ensure that the movable part 28 is reset in the non-working state, realizing the smooth progress of the picking link in the automated operation of the machining center.

[0031] See attached Figure 7and attached Figure 8 A sliding groove 31 is provided on the surface of the connecting member 30 , and a fixed column 21 is slidably connected inside the sliding groove 31 , and the fixed column 21 is fixedly connected to the movable frame 15 .

[0032] When the user starts the motor 13 and drives the second threaded rod 14 to rotate and make the movable frame 15 descend for milling processing, the fixed column 21 fixedly connected to the movable frame 15 moves downward accordingly. Due to the sliding groove 31 of the fixed column 21 opened on the surface of the connecting member 30, the special shape and direction of the sliding groove 31 make the fixed column 21 generate a lateral thrust on the connecting member 30 during the vertical descending process, pushing the connecting member 30 to slide along the fifth sliding rod 29, thereby driving the limit block 32 on one side of the connecting member 30 to move forward until the limit block 32 is stuck in the fixed block 20 on the movable seat 6 to lock the movable seat 6. When the milling is completed, the motor 13 drives the second threaded rod 14 to rotate in the opposite direction and make the movable frame 15 rise, the fixed column 21 slides in the opposite direction in the sliding groove 31, the thrust direction is changed, the connecting member 30 moves in the opposite direction, and the limit block 32 is separated from the fixed block 20, realizing the automatic locking and unlocking of the movable seat 6, ensuring the stability of the movable seat 6 during the processing, improving the processing accuracy, simplifying the operation process, and reducing the risk of equipment failure.

[0033] See attached Figure 2 and attached Figure 4 The top of the base 1 is fixedly connected to the shell 2, and multiple first sliding rods 4 are fixedly connected between the left and right sides of the inner wall of the shell 2. The multiple first sliding rods 4 are all slidably connected to the sliding plate 5.

[0034] Specifically, the shell 2 can protect the waveguide structure body 12, prevent dust, chips and other debris from entering and affecting the operation of the equipment, and prevent debris generated during processing from splashing. The multiple first sliding rods 4 fixedly connected on the left and right sides of the inner wall of the shell 2 provide sliding guides for the sliding plate 5, so that the sliding plate 5 can move stably along the first sliding rod 4 during the opening and closing process to avoid shaking or deviation.

[0035] See attached Figure 3 and attached Figure 6 A plurality of second slide bars 11 are fixedly connected to one side of the movable seat 6 , and the plurality of second slide bars 11 are all slidably connected to adjacent clamping members 10 .

[0036] Specifically, the second slide bar 11 provides a sliding track for the clamping member 10, so that the clamping member 10 can move stably along the second slide bar 11, ensuring the accuracy of the clamping action. The uniform distribution of multiple second slide bars 11 can make the clamping member 10 more evenly stressed during movement, avoiding tilting or jamming.

[0037] See attached Figure 2 and attached Figure 4A water tank 16 is fixedly connected to the top of the mobile frame 15, and a water pump 17 is provided on one side of the water tank 16. The input end of the water pump 17 is fixedly arranged between the water tank 16, and a delivery pipe 18 is fixedly provided at the output end of the water pump 17. The delivery pipe 18 is fixedly connected to the mobile frame 15, and a plurality of nozzles 19 are fixedly connected to the surface of the delivery pipe 18.

[0038] Specifically, when milling is performed, the water tank 16 fixed on the top of the mobile frame 15 will descend to the processing area with the mobile frame 15, and the water pump 17 will be started to extract coolant from the water tank 16. The coolant will be evenly sprayed onto the waveguide structure body 12 and the milling mechanism 22 through the delivery pipe 18 and multiple nozzles 19 to cool and lubricate the milling parts, thereby realizing automatic delivery and spraying of coolant during the milling process, effectively reducing the temperature of the milling mechanism 22 and the waveguide structure body 12, reducing tool wear, and improving processing accuracy and surface quality. At the same time, the coolant can also wash away the chips generated by the processing, keep the processing area clean, and ensure the smooth progress of the processing.

[0039] See attached Figure 3 and attached Figure 6 The movable seat 6 is fixedly connected to a side away from the first threaded rod 7 with a plurality of fixed blocks 20 . The plurality of fixed blocks 20 penetrate and extend into the interior of the back plate 3 . The plurality of fixed blocks 20 are all slidably connected to the back plate 3 .

[0040] Specifically, the movable seat 6 can be fixed by clamping the fixed block 20 with the limiting block 32 to prevent the movable seat 6 from sliding left and right, thereby affecting the processing accuracy.

[0041] See attached Figure 8 The rear side of the movable frame 15 passes through and extends into the interior of the connecting member 30 , and the movable frame 15 and the connecting member 30 are slidably connected.

[0042] Specifically, when the movable frame 15 moves up and down, it will slide inside the connecting member 30. When sliding upward, it will push the movable member 28 to move upward, thereby driving the two sliding plates 5 to open, and the connecting member 30 will move by sliding in the slide groove 31 through the fixed column 21, thereby unlocking and fixing the movable seat 6.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
