Description

Technical Field

[0001] This invention relates to the field of metal processing, and in particular to an apparatus and method for processing annular holes in the reflective surface of microwave antennas. Background Technology

[0002] With the development of industrial technology, the modern communication industry has become more and more sophisticated. Communication equipment requires the installation of many microwave antennas, which in turn require the installation of many reflective surfaces. These reflective surfaces need to be mass-produced, and many holes need to be drilled in the reflective surface's lid for assembly. In the past, drilling equipment still required manual intervention, which increased labor costs.

[0003] For example, patent number 201910752915.5 discloses a drilling device for processing the central annular hole of a microwave antenna reflector. The device includes a base, a sleeve vertically fixed on the base, a positioning mechanism set on the top of the sleeve for positioning the microwave antenna reflector, a clamping mechanism set in the sleeve for fixing the microwave antenna reflector on the positioning mechanism, and a drilling mechanism set on the outer periphery of the sleeve for simultaneously completing the processing of the central annular hole of the microwave antenna reflector. The positioning mechanism includes a positioning cylinder concentrically fixed on the top of the sleeve and a tray fitted on the outer periphery of the positioning cylinder. The outer diameter of the positioning cylinder corresponds to the diameter of the central hole of the microwave antenna reflector, and the shape of the upper edge of the tray is an arc corresponding to the curvature of the microwave antenna reflector.

[0004] The device has the following drawbacks when in use: First, it requires manual intervention when punching holes, which is not only slow but also not precise enough. Second, the reflective surface is prone to excessive stress during processing, which can easily cause the surface to be distorted. Excessive distortion of the surface will result in the product being unqualified. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a device and method for processing annular holes on the reflector surface of microwave antennas. The antenna dish to be processed is placed upside down on an arc-shaped block at the top of an angle turntable. A servo motor at the bottom of the fixed base then drives the angle turntable to rotate. The turntable stops after each unit of rotation. A hydraulic press at the top of the load-bearing bridge extends an impact rod, which passes through the side wall of the antenna dish and inserts into the discharge hole. The small circular pieces impacted from the discharge hole fall into the concave cavity at the center of the arc-shaped block for waste storage, achieving an automatic punching effect without human intervention.

[0006] To solve the above problems, the present invention provides the following technical solution: a device for processing annular holes on the reflector surface of a microwave antenna, comprising a fixed base, an angle turntable at the top of the fixed base, the angle turntable and the fixed base being rotatably connected, a servo motor fixedly mounted at the bottom of the fixed base, the output rod of the servo motor passing through the bottom surface of the fixed base and the angle turntable and being fixedly connected, a locking assembly at the top of the angle turntable, and an antenna dish on the locking assembly, the locking assembly comprising an arc-shaped locking block, the arc-shaped locking block and the top surface of the angle turntable being integrally formed, and a plurality of discharge holes being provided on the outer side of the arc-shaped locking block, the discharge holes forming a 30-degree angle with the horizontal plane, a load-bearing bridge on the side wall of the fixed base, a hydraulic press at the top of the load-bearing bridge, an impact rod at the end of the hydraulic press, a slotted plate on the side of the fixed base opposite to the load-bearing bridge, a slotting assembly at the top of the slotted plate, a detection platform on one side of the fixed base, and a detection mechanism at the top of the detection platform.

[0010] Furthermore, the locking force assembly includes a positioning cylinder, and hinge blocks are fixedly installed on the side wall of the slotted plate and the side wall of the closing bridge. The bottom end of the positioning cylinder is hinged to the hinge block on the side wall of the slotted plate, and the output rod of the positioning cylinder is hinged to the hinge block on the side wall of the closing bridge. Two clips and a shaft seat are also fixedly installed at the top of the slotted plate. A torsion crossbar is provided at the bottom of the closing bridge and inserted inside the clips and the shaft seat. Two blocking triangular blocks are also provided at the top of the slotted plate. When the closing bridge is in the vertical position, it is attached to the side wall of the blocking triangular blocks.

[0011] Furthermore, the linear propulsion assembly includes a linear motor, which is fixed to the side wall of the closing bridge. The output end of the linear motor is provided with a threaded rod, and a nut block that matches the threaded rod is provided on the platform.

[0012] Furthermore, the detection mechanism includes a torsion table, a column at the bottom of the torsion table, a positioning bearing at the top of the detection platform, the outer ring of the positioning bearing being fixedly connected to the detection platform, the column being inserted into the inner ring of the positioning bearing, the column being connected to a rotational power mechanism, a contour detection mechanism being provided on the side wall of the detection platform, and a ring magnet being provided on the inner side of the torsion table.

[0013] Furthermore, the rotary power mechanism includes a driven wheel, a reduction wheel is provided on one side of the driven wheel, the reduction wheel and the driven wheel are connected by an acceleration belt, the reduction wheel is installed on the output end of the reduction motor, the reduction motor is fixed to the bottom end of the detection platform, and the diameter ratio of the reduction wheel to the driven wheel is 1:2.

[0014] Furthermore, the contour detection mechanism includes a cantilever bridge, the bottom end of which is fixedly connected to the bottom surface of the detection platform. Reinforcing ribs are provided at both corners of the cantilever bridge. A detection box is slidably fitted onto the top of the cantilever bridge. A telescopic rod is provided at the detection end of the detection box. A steel ball is detachably installed at the bottom end of the telescopic rod. The outer side of the steel ball is coated with organic oil. An indicator light is connected to the top end of the telescopic rod.

[0015] Furthermore, the marking mechanism includes a printing table, a driven column rotatably mounted on the top of the printing table, an ink pad turntable mounted on the top of the driven column, four expansion grooves mounted on the top of the ink pad turntable, expansion rods slidably mounted on the inner side of the expansion grooves, the ends of the expansion rods being connected to the expansion grooves via soft springs, and ink pad blocks being detachably mounted on the other ends of the expansion rods. A ramp block is also mounted on the top of the expansion rods. An expansion bridge is mounted on the bottom of the printing table, and an expansion cylinder is mounted on the top of the expansion bridge. A plastic ball is mounted on the output end of the expansion cylinder, and the plastic ball is attached to the ramp block. An output turntable is mounted on the outer side of the driven column, and an angle turntable is mounted on the bottom of the angle turntable, which is connected to the printing turntable. The output turntable and the printing turntable are connected by a grid belt.

[0016] Furthermore, it includes the following steps:

[0017] S1. Place the antenna dish to be processed upside down on the arc-shaped block at the top of the angle turntable, and then the servo motor at the bottom of the fixed base starts to drive the angle turntable to rotate. When the angle turntable rotates by one unit angle each time, it stops. The hydraulic press at the top of the load-bearing bridge drives the impact rod to extend out, so that the impact rod passes through the side wall of the antenna dish and inserts into the discharge hole. The small circular pieces impacted out of the discharge hole will fall into the concave cavity in the center of the arc-shaped block for waste storage.

[0018] S2. The positioning cylinder at the top of the slotted plate drives the merging bridge to start to rotate, so that the side wall of the merging bridge fits against the blocking triangular block. The blocking triangular block increases the stability of the merging bridge. At the same time, the linear motor drives the platform to move through the threaded rod. The platform and the slotted motor can slide linearly along the merging guide rail. The drilling rod of the slotted motor cuts a groove on the side wall of the antenna dish for assembling the steel reinforcement frame.

[0019] S3. Remove the finished antenna dish and place it on the torsion table. The ring magnet inside the torsion table can lock the position of the antenna dish. Then, manually remove the detection box so that the steel ball fits against the edge of the antenna dish. The reduction motor drives the driven wheel to rotate through the reduction wheel and the acceleration belt. The torsion table rotates with the driven wheel. If the outline of the antenna dish is twisted during the processing, the extension and retraction of the steel ball will exceed the set value. The extension rod touches the indicator light. When the indicator light lights up, it means that the outline of the antenna dish has been excessively twisted during the drilling process and should be scrapped.

[0020] The beneficial effects of this invention are:

[0021] Firstly, the antenna dish to be processed is placed upside down on the arc-shaped block at the top of the angle turntable. Then, the servo motor at the bottom of the fixed base starts to drive the angle turntable to rotate. When the angle turntable rotates by one unit angle, it stops. The hydraulic press at the top of the load-bearing bridge drives the impact rod to extend out, allowing the impact rod to pass through the side wall of the antenna dish and insert into the discharge hole. The small circular pieces impacted out of the discharge hole fall into the concave cavity in the center of the arc-shaped block for waste storage, achieving the effect of automatic punching without human intervention. While the angle turntable rotates, it drives the driven column to rotate through the grid belt. The ink pad turntable rotates synchronously with the angle turntable. When the ink pad turntable rotates by one unit angle, the expansion cylinder drives the plastic ball to move downward and squeeze the ramp block. The four expansion rods expand outward at the same time. The ink pad blocks at the ends of the four expansion rods can be used to mark trademarks or the location of the next process on metal parts.

[0022] Secondly, the positioning cylinder at the top of the slotted plate drives the merging bridge to begin to twist, so that the side wall of the merging bridge fits against the blocking triangular block. The blocking triangular block increases the stability of the merging bridge. At the same time, the linear motor drives the platform to move through the threaded rod. The platform and the slotted motor can slide linearly along the merging guide rail. The drilling rod of the slotted motor cuts a groove on the side wall of the antenna dish for assembling the steel reinforcement frame.

[0023] Third, the finished antenna dish is removed and placed on the torsion table. The ring magnet inside the torsion table can lock the position of the antenna dish. Then, the detection box is manually removed so that the steel ball fits against the edge of the antenna dish. The reduction motor drives the driven wheel to rotate through the reduction wheel and the acceleration belt. The torsion table rotates with the driven wheel. If the outline of the antenna dish is twisted during the processing, the extension and retraction of the steel ball will exceed the set value. The extension rod touches the indicator light. When the indicator light is lit, it means that the outline of the antenna dish has been excessively twisted during the drilling process and should be scrapped. Attached Figure Description

[0035] Reference Figure 1 , 2 A device for processing annular holes on a microwave antenna reflector, as shown in figures 3, 4, 5, and 6, includes a fixed base 1. An angle turntable 2 is mounted on the top of the fixed base 1, and the angle turntable 2 is rotatably connected to the fixed base 1. A servo motor 9 is fixedly mounted on the bottom of the fixed base 1. The output rod of the servo motor 9 passes through the bottom surfaces of the fixed base 1 and the angle turntable 2 and is fixedly connected. A locking assembly is mounted on the top of the angle turntable 2, and an antenna dish 3 is mounted on the locking assembly. The locking assembly includes an arc-shaped locking block 201, which is integrally formed with the top surface of the angle turntable 2. Several discharge holes 202 are provided on the outer side of the arc-shaped locking block 201, forming a 30-degree angle with the horizontal plane. A load-bearing bridge 6 is also provided on the side wall of the fixed base 1, and a load-bearing bridge 6 is positioned at its top. A hydraulic press 601 is provided, with an impact rod at its end. A slotted plate 4 is provided on the side of the fixed base 1 facing away from the load-bearing bridge 6, and a slotting component is provided at the top of the slotted plate 4. A detection platform 7 is also provided on one side of the fixed base 1, and a detection mechanism is provided at the top of the detection platform 7. The antenna dish 3 to be processed is placed upside down on the arc-shaped locking block 201 at the top of the angle turntable 2. The angle turntable 2 stops after each unit angle rotation. The hydraulic press 601 at the top of the load-bearing bridge 6 drives the impact rod to extend out, allowing the impact rod to pass through the side wall of the antenna dish 3 and insert into the discharge hole 202. The small circular pieces impacted out of the discharge hole 202 fall into the concave cavity in the center of the arc-shaped locking block 201 for waste storage, achieving the effect of automatic punching without human intervention.

[0036] The outer side of the arc-shaped locking block 201 has three recesses, in which electromagnets are installed. The openings of the recesses are provided with sealing covers made of plastic. After the antenna dish 3 is placed upside down on the arc-shaped locking block 201 at the top of the angle turntable 2, the electromagnet is energized to hold the antenna dish 3 in place, locking the antenna dish 3 and the angle turntable 2 together.

[0037] The impact rod has a threaded hole at its end, and an impact head is fixed to the threaded hole by a countersunk bolt. The impact head is made of high-speed steel, which increases the hardness of the impact and prevents the impact rod from wearing out too quickly.

[0038] The slotting assembly includes a merging bridge 5, which is rotatably connected to the top surface of the slotting plate 4 via a locking assembly. Two merging guide rails 501 are fixedly installed on the side wall of the merging bridge 5, and a merging slider 502 is slidably installed on the merging guide rails 501. A platform 503 is fixedly installed on the side wall of the merging slider 502, and a slotting motor 504 is fixedly installed on the side wall of the platform 503. The platform 503 is connected to a linear propulsion assembly. The merging bridge 5 rotates around the top surface of the slotting plate 4 to bring the merging bridge 5 closer to the antenna dish 3. The slotting motor 504 slides linearly along the merging guide rails 501 with the platform 503, allowing the drill rod of the slotting motor 504 to cut into the side wall of the antenna dish 3 to perform slotting operations. The slotted grooves serve as the skeleton for assembling the reinforcing bars.

[0039] The locking assembly includes a positioning cylinder 403. Hinges 404 are fixedly installed on the side walls of both the slotted plate 4 and the closing bridge 5. The bottom end of the positioning cylinder 403 is hinged to the hinge block 404 on the side wall of the slotted plate 4. The output rod of the positioning cylinder 403 is also hinged to the hinge block 404 on the side wall of the closing bridge 5. Two clips and a shaft seat 401 are also fixedly installed at the top of the slotted plate 4. The bottom end of the closing bridge 5 is provided with a clamp that passes through the clips and shaft seat 401. The top of the slotted plate 4 is also equipped with two blocking triangular blocks 402. When the merging bridge 5 is in the vertical position, it is attached to the side wall of the blocking triangular blocks 402. The positioning cylinder 403 at the top of the slotted plate 4 drives the merging bridge 5 to start to twist, so that the side wall of the merging bridge 5 is attached to the blocking triangular blocks 402. The blocking triangular blocks 402 increase the stability of the merging bridge 5, prevent the merging bridge 5 from shaking during the processing operation, and reduce the processing error.

[0040] The linear propulsion assembly includes a linear motor 505, which is fixed to the side wall of the merging bridge 5. The output end of the linear motor 505 is provided with a threaded rod 506. The platform 503 is provided with a nut block that matches the threaded rod 506. After the merging bridge 5 is erected, the linear motor 505 drives the platform 503 to slide along the merging guide rail 501 through the threaded rod 506.

[0041] The detection mechanism includes a torsion table 701, a column 702 at the bottom of the torsion table 701, a positioning bearing at the top of the detection platform 7, the outer ring of the positioning bearing being fixedly connected to the detection platform 7, the column 702 being inserted into the inner ring of the positioning bearing, and the column 702 being connected to a rotational power mechanism. A contour detection mechanism is also provided on the side wall of the detection platform 7. An annular magnet 703 is provided on the inner side of the torsion table 701. The processed antenna dish 3 is taken off and placed on the torsion table 701. The annular magnet 703 inside the torsion table 701 can lock the position of the antenna dish. When the torsion table 701 and the antenna dish 3 inside it rotate, the contour detection mechanism detects whether the ring of the antenna dish 3 has been twisted too much during processing.

[0042] The rotary power mechanism includes a driven wheel 704, a reduction wheel 705 on one side of the driven wheel 704, and the reduction wheel 705 and the driven wheel 704 are connected by an acceleration belt 706. The reduction wheel 705 is mounted on the output end of a reduction motor 707, which is fixed to the bottom of the detection platform 7. The diameter ratio of the reduction wheel 705 to the driven wheel 704 is 1:2. The reduction motor 707 drives the driven wheel 704 to rotate through the reduction wheel 705 and the acceleration belt 706. The torsion table 701 rotates along with the driven wheel 704. The reduction wheel 705 increases the torque of the driven wheel 704 by stepping, and also increases the accuracy of the rotation of the driven wheel 704.

[0043] The contour detection mechanism includes a cantilever bridge 8, the bottom end of which is fixedly connected to the bottom surface of the detection platform 7. Reinforcing ribs 801 are provided at both corners of the cantilever bridge 8. A detection box 802 is slidably fitted onto the top of the cantilever bridge 8. A telescopic rod is provided at the detection end of the detection box 802. A steel ball 803 is detachably installed at the bottom of the telescopic rod. The outer side of the steel ball 803 is coated with organic oil. An indicator light is connected to the top of the telescopic rod. When the extension or retraction of the steel ball 803 exceeds a set value, the telescopic rod touches the indicator light, and the indicator light illuminates, indicating that the contour of the antenna dish has been excessively distorted during the drilling process, and it should be scrapped.

[0044] The marking mechanism includes a printing table 10. A driven column 1001 is rotatably mounted on the top of the printing table 10. An ink pad turntable 1003 is mounted on the top of the driven column 1001. Four expansion grooves are provided on the top of the ink pad turntable 1003. An expansion rod 1004 is slidably mounted on the inner side of the expansion groove. The end of the expansion rod 1004 is connected to the expansion groove via a soft spring. An ink pad block 1005 is detachably mounted on the other end of the expansion rod 1004. A ramp block 1006 is also provided on the top of the expansion rod 1004. An expansion bridge 1009 is provided at the bottom of the printing table 10. An expansion cylinder 1007 is provided on the top of the expansion bridge 1009. A plastic ball 1008 is installed at the output end of the expansion cylinder 1007 and is attached to the ramp block. On the slope of 1006, a 1002 is fitted on the outer side of the driven column 1001. An output turntable is set at the bottom of the angle turntable 2 and docks with the printing turntable 1002. The output turntable and the printing turntable 1002 are connected by a grid belt. When the angle turntable 2 rotates, it drives the driven column 1001 to rotate through the grid belt. The ink pad turntable 1003 will rotate synchronously with the angle turntable 2. When the ink pad turntable 1003 rotates by one unit angle, the expansion cylinder 1007 drives the plastic ball 1008 to move downward and squeeze the slope block 1006. The four expansion rods 1004 expand outward at the same time. The ink pad blocks 1005 at the ends of the four expansion rods 1004 can mark the trademark or the position mark of the next process on the metal parts.

[0045] Includes the following steps,

[0046] S1. The antenna dish 3 to be processed is placed upside down on the arc-shaped block 201 at the top of the angle turntable 2, and then the servo motor 9 at the bottom of the fixed base 1 starts to drive the angle turntable 2 to rotate. When the angle turntable 2 rotates by one unit angle, it stops. The hydraulic press 601 at the top of the load-bearing bridge 6 drives the impact rod to extend out, so that the impact rod passes through the side wall of the antenna dish 3 and inserts into the discharge hole 202. The small circular pieces impacted out of the discharge hole 202 will fall into the concave cavity in the center of the arc-shaped block 201 for waste storage.

[0047] S2. The positioning cylinder 403 at the top of the slotted plate 4 drives the closing bridge 5 to start to rotate, so that the side wall of the closing bridge 5 fits against the blocking triangle block 402. The blocking triangle block 402 increases the stability of the closing bridge 5. At the same time, the linear motor 505 drives the platform 503 to move through the threaded rod 506. The platform 503 and the slotted motor 504 can slide linearly along the closing guide rail 501. The drilling rod of the slotted motor 504 cuts a groove on the side wall of the antenna dish 3 for assembling the steel reinforcement frame.

[0048] S3. Remove the finished antenna dish 3 and place it on the torsion table 701. The annular magnet 703 inside the torsion table 701 can lock the position of the antenna dish 3. Then, manually remove the detection box 802 so that the steel ball 803 fits against the edge of the antenna dish 3. The reduction motor 707 drives the driven wheel 704 to rotate through the reduction wheel 705 and the acceleration belt 706. The torsion table 701 rotates with the driven wheel 704. If the outline of the antenna dish 3 is twisted during the processing, the extension and retraction of the steel ball 803 will exceed the set value. The extension rod touches the indicator light. When the indicator light lights up, it means that the outline of the antenna dish 3 has been excessively twisted during the drilling process and should be scrapped.

[0049] Finally, the antenna dish 3 to be processed is placed upside down on the arc-shaped locking block 201 at the top of the angle turntable 2. The angle turntable 2 stops after each unit of rotation. The hydraulic press 601 at the top of the load-bearing bridge 6 drives the impact rod to extend, passing through the side wall of the antenna dish 3 and inserting into the discharge hole 202. The small circular pieces impacted out of the discharge hole 202 fall into the concave cavity in the center of the arc-shaped locking block 201 for waste storage, achieving an automatic punching effect without manual intervention. After the antenna dish 3 is upside down on the arc-shaped locking block 201 at the top of the angle turntable 2... When the electromagnet is energized, it attracts the antenna dish 3, locking the antenna dish 3 and the angle turntable 2. The impact head increases the impact hardness to prevent the impact rod from wearing out too quickly. The merging bridge 5 rotates around the top surface of the slotted plate 4, bringing the merging bridge 5 closer to the antenna dish 3. The slotting motor 504 slides linearly along the merging guide rail 501 with the platform 503, allowing the drill rod of the slotting motor 504 to cut into the side wall of the antenna dish 3 to perform slotting operations. The slotted grooves serve as the skeleton for assembling the reinforcing bars. The positioning cylinder 403 at the top of the slotted plate 4 drives the merging bridge 5 to begin to rotate, allowing the merging bridge 5 to... The sidewalls are attached to the blocking triangular blocks 402, which increase the stability of the merging bridge 5, preventing it from shaking during processing and reducing machining errors. After the merging bridge 5 is erected, the linear motor 505 drives the platform 503 to slide along the merging guide rail 501 via the threaded rod 506, removing the processed antenna dish 3 and placing it on the torsion table 701. The annular magnet 703 inside the torsion table 701 can lock the position of the antenna dish. When the torsion table 701 and the antenna dish 3 inside it rotate, the contour detection mechanism... Check if the ring buckle of the antenna dish 3 has been excessively twisted during processing. The geared motor 707 drives the driven wheel 704 to rotate through the geared wheel 705 and the acceleration belt 706. The torsion table 701 rotates together with the driven wheel 704. The geared wheel 705 increases the torque of the driven wheel 704 in steps and increases the accuracy of the rotation of the driven wheel 704. The extension and retraction of the steel ball 803 will exceed the set value. When the extension rod touches the indicator light 803, the indicator light will light up, indicating that the outline of the antenna dish has been excessively twisted during the drilling process, and it should be scrapped.

[0050] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention.

Place the antenna dish (3) to be processed upside down on the arc-shaped block (201) at the top of the angle turntable (2), and then fix the servo motor (9) at the bottom of the base (1) to start driving the angle turntable (2) to rotate. When the angle turntable (2) rotates by one unit angle each time, it stops. The hydraulic press (601) at the top of the load-bearing bridge (6) drives the impact rod to extend out, so that the impact rod passes through the side wall of the antenna dish (3) and inserts into the discharge hole (202). The small circular pieces impacted out of the discharge hole (202) will fall into the concave cavity in the center of the arc-shaped block (201) for waste storage. S2.
