Description

Technical Field

[0001] This application belongs to the field of duplexer fixture technology, specifically a duplexer multi-angle stabilizing fixture. Background Technology

[0002] A duplexer is an electronic device used to simultaneously transmit and receive signals. It is commonly used in communication systems, especially in radio and satellite communications. A duplexer enables both transmission and reception on a shared frequency, while signal isolation is achieved through different frequencies or polarizations. The main function of a duplexer is to improve spectrum utilization, enabling communication systems to transmit data more efficiently. It has wide applications in wireless microphones, wireless communication base stations, satellite communications, and other fields. A duplexer typically includes transmit filters, receive filters, and switching devices to ensure correct signal transmission and reception.

[0003] In existing duplex machining processes, fixtures play a crucial role, holding the duplexer to ensure precise machining by subsequent equipment. However, when faced with complex machining tasks requiring adjustment of the duplexer's tilt angle, existing fixture systems have significant shortcomings. While these fixtures can meet basic machining needs, they cannot quickly and accurately adjust for specific machining requirements that necessitate changing the duplexer's tilt angle. This limitation leads to reduced machining efficiency and fails to meet the demands of modern industrial production for high-efficiency, high-precision machining. Therefore, a multi-angle stabilizing fixture for duplexers is proposed. Utility Model Content

[0004] The purpose of this application is to provide a duplexer multi-angle stabilizing fixture in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: A duplexer multi-angle stabilizing clamp includes a housing, a mounting base rotatably connected inside the housing, a circular hollow ring fixedly mounted on the top surface of the mounting base by bolts, a circular housing on the top surface of the circular hollow ring, a rotation adjustment mechanism for adjusting position inside the circular housing, a placement plate on the top surface of the circular housing, two L-shaped support rods symmetrically fixedly mounted on the outer surface of the circular housing, and a fixing plate fixedly mounted on the end of each L-shaped support rod away from the circular housing, an electric cylinder fixedly mounted on the top surface of the fixing plate, a clamping plate fixedly mounted on the telescopic end of the electric cylinder, a groove opened on the bottom surface of the mounting base, an arc plate fixedly mounted inside the groove, a plurality of toothed blocks evenly arrayed on the bottom surface of the arc plate, a universal motor fixedly mounted on the inner bottom surface of the housing, a gear one fixedly mounted on the drive end of the universal motor, and the gear one meshing with the toothed blocks.

[0006] In a preferred embodiment, the rotation adjustment mechanism includes an annular internal gear ring, a reduction motor, and a second gear. The annular internal gear ring is fixedly installed on the inner sidewall of the circular housing. The reduction motor is fixedly installed on the top surface of the mounting base inside the circular housing. The second gear is fixedly installed on the drive end of the reduction motor, and the second gear meshes with the annular internal gear ring.

[0007] In a preferred embodiment, the top surface of the circular housing has a circular through hole, and a circular mounting plate is disposed inside the circular through hole. An electric push rod is fixedly mounted through the top surface of the circular mounting plate. The telescopic end of the electric push rod is fixed to the bottom surface of the placement plate, and the bottom end of the electric push rod is fixed to the top surface of the mounting base.

[0008] In a preferred embodiment, a circular groove is provided on the top surface of the circular hollow ring, and a limiting connecting post is slidably connected inside the circular groove. The top end of the limiting connecting post is fixed to the bottom surface of the circular shell.

[0009] In a preferred embodiment, a circular positioning ring is fixedly installed on the top surface of the placement plate near the center.

[0010] In a preferred embodiment, a plurality of second fixing plates are fixedly installed on the side of the housing, and the top surface of the plurality of second fixing plates is provided with through holes.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0012] 1. In this application, due to the adoption of the above-mentioned scheme, when the operator needs to adjust the tilt angle of the clamped duplexer, the general-purpose motor is first started. The rotation of the general-purpose motor will drive the gear one to rotate. Since the gear one is meshed with the tooth block, this rotation will further drive the mounting base, the circular shell, the L-shaped support rod, the electric cylinder and the clamping plate to rotate left and right. Through this mechanism, the operator can easily adjust the tilt angle of the duplexer so as to perform machining at different angles. Through the set rotation adjustment mechanism, not only can the position of the circular shell and the clamped duplexer be easily adjusted, but machining can also be performed at different positions of the duplexer. At the same time, the rotation function of the mounting base allows the duplexer to perform machining at different tilt angles, which greatly improves the flexibility of operation and ensures the machining accuracy and convenience of operation.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] refer to Figures 1-6 A duplexer multi-angle stabilizing clamp includes a housing 1. Multiple second fixing plates 25 are fixedly installed on the side of the housing 1, and each of the second fixing plates 25 has a through hole on its top surface. A mounting base 2 is rotatably connected inside the housing 1. The second fixing plates 25 facilitate the use of bolts to pass through the through holes, thus making it easy for personnel to install and fix the housing 1 in a suitable position. Limiting holes are opened on the left and right sides of the mounting base 2. Protrusions are fixedly installed on the inner side wall of the housing 1, so that the protrusions can be inserted into the limiting holes, thereby achieving the effect of the mounting base 2 rotating inside the housing 11.

[0022] refer to Figure 1 , Figure 2 A circular hollow ring 3 is fixedly installed on the top surface of the mounting base 2 by bolts. The circular hollow ring 3 is fixed by bolts, which makes it easy for personnel to disassemble and install the circular hollow ring 3, thus improving convenience.

[0023] refer to Figure 1 , Figure 2 and Figure 4 A circular groove 22 is provided on the top surface of the circular hollow ring 3. A limiting connecting post 23 is slidably connected inside the circular groove 22. The top of the limiting connecting post 23 is fixed to the bottom surface of the circular shell 4. The circular groove 22 facilitates the sliding of the limiting connecting post 23 inside it. The limiting connecting post 23 is composed of a disc and a cylinder, which facilitates sliding inside the circular groove 22 and prevents it from easily detaching from it. This makes the circular shell 4 more stable during subsequent rotation.

[0024] refer to Figure 1 , Figure 2 A circular shell 4 is provided on the top surface of the circular hollow ring 3. A rotation adjustment mechanism 5 for adjusting the position is provided inside the circular shell 4. The rotation adjustment mechanism 5 facilitates the rotation of the circular shell 4, thereby making it easy to adjust the position of the circular shell 4 and improving convenience.

[0025] refer to Figure 1 , Figure 2 and Figure 5 The rotary adjustment mechanism 5 includes an annular internal gear ring 16, a reduction motor 17, and a second gear 18. The annular internal gear ring 16 is fixedly installed on the inner side wall of the circular housing 4. The reduction motor 17 is fixedly installed on the top surface of the mounting base 2 inside the circular housing 4. The second gear 18 is fixedly installed on the drive end of the reduction motor 17, and the second gear 18 meshes with the annular internal gear ring 16. The reduction motor 17 drives the second gear 18 to rotate. Since the second gear 18 meshes with the annular internal gear ring 16, it is convenient for the second gear 18 to drive the annular internal gear ring 16 and the circular housing 4 to rotate and adjust their positions.

[0026] refer to Figure 1 , Figure 2 and Figure 6 A placement plate 6 is provided on the top surface of the circular shell 4. A circular positioning ring 24 is fixedly installed on the top surface of the placement plate 6 near the center. A circular through hole 19 is opened on the top surface of the circular shell 4. A circular mounting plate 20 is provided inside the circular through hole 19. An electric push rod 21 is fixedly installed through the top surface of the circular mounting plate 20. The telescopic end of the electric push rod 21 is fixed to the bottom surface of the placement plate 6, and the bottom end of the electric push rod 21 is fixed to the top surface of the mounting base 2. Since the bottom end of the electric push rod 21 is fixed to the top surface of the mounting base 2, the circular mounting plate 20 and the electric push rod 21 will not rotate when the circular shell 4 rotates. The electric push rod 21 facilitates the upward movement of the placement plate 6, which facilitates the clamping operation of the duplexer on the placement plate 6.

[0027] refer to Figure 1 , Figure 2Two L-shaped support rods 7 are symmetrically fixedly installed on the outer surface of the circular shell 4, and a fixing plate 8 is fixedly installed on the end of each L-shaped support rod 7 away from the circular shell 4. An electric cylinder 9 is fixedly installed on the top surface of the fixing plate 8, and a clamping plate 10 is fixedly installed on the telescopic end of the electric cylinder 9. The L-shaped support rods 7 facilitate the installation and fixation of the fixing plate 8. When the placement plate 6 drives the duplexer to move upward, the personnel start the electric cylinder 9. The electric cylinder 9 drives the clamping plate 10 to move towards the duplexer, so that the clamping rod at the front end of the clamping plate 10 can clamp the duplexer.

[0028] refer to Figure 1 , Figure 2 and Figure 3 The mounting base 2 has a groove 11 on its bottom surface. An arc-shaped plate 12 is fixedly installed inside the groove 11. Multiple toothed blocks 13 are evenly arranged on the bottom surface of the arc-shaped plate 12. A universal motor 14 is fixedly installed on the bottom surface inside the housing 1. A gear 15 is fixedly installed on the drive end of the universal motor 14. The gear 15 meshes with the toothed blocks 13. When the user starts the universal motor 14, the universal motor 14 drives the gear 15 to rotate. Since the gear 15 meshes with the toothed blocks 13, it is easy to drive the mounting base 2, the circular housing 4, the L-shaped support rod 7, the electric cylinder 9, and the clamping plate 10 to rotate. This makes it easy to adjust the tilt angle of the duplexer held by the clamping plate 10, thus facilitating the machining operation of the duplexer.

[0029] The implementation principle of the multi-angle stabilizing clamp of the duplexer in this application is as follows: When the operator performs machining on the duplexer, firstly, the operator places the duplexer on the top surface of the placement plate 6 and ensures that the middle part of the duplexer is aligned with the circular positioning ring 24 for preliminary positioning. Then, the operator starts the electric push rod 21 to push the placement plate 6 upward. At the same time, the operator also starts the electric cylinder 9, which drives the two clamping plates 10 to move towards the duplexer, thereby firmly clamping the duplexer between the clamping plates 10 to facilitate machining operations.

[0030] When the tilt angle of the clamped duplexer needs to be adjusted, the operator starts the universal motor 14. The rotation of the universal motor 14 drives the gear 15 to rotate. Since the gear 15 meshes with the tooth block 13, this rotation further drives the mounting base 2, the circular housing 4, the L-shaped support rod 7, the electric cylinder 9, and the clamping plate 10 to rotate left and right. Through this mechanism, the operator can easily adjust the tilt angle of the duplexer to perform machining at different angles. Through the set rotation adjustment mechanism 5, not only can the position of the circular housing 4 and the clamped duplexer be easily adjusted, but machining can also be performed at different positions of the duplexer. At the same time, the rotation function of the mounting base 2 allows the duplexer to perform machining at different tilt angles, greatly improving the flexibility of operation. This comprehensive machining adjustment system not only improves machining efficiency but also ensures machining accuracy and ease of operation.

[0031] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
