[0025] Example 1

[0026] See also Figures 1 to 4The embodiment of the utility model provides a new processing fixture for antenna waveguide plate, including a base and a fixture; the base 10 is the main part of the fixture, and the base 10 provides basic support when processing the antenna waveguide plate; the base 10 is a solid structure made of materials such as aluminum alloy or steel. The base 10 is a rectangular plate and includes a protrusion 11 arranged at the center of the rectangular plate; the fixture includes a pressurizing component 20, which is arranged around the periphery of the protrusion 11 on the base 10 to fully cover the installation position of the waveguide plate; the function of these pressurizing components 20 is to fix the antenna waveguide plate to keep it stable during the processing process, and it can provide sufficient clamping force to ensure that the waveguide plate does not move or shake.

[0027] At least one pair of pressurizing components 20 are respectively provided at both ends of the base 10; at least four pressurizing components 20 are respectively provided at both sides of the base 10; the pressurizing components 20 are detachably connected to the base 10; by providing various numbers of pressurizing components 20 and making them detachably installed, it can be adjusted according to requirements, and the requirements can be different requirements such as the shape, size, thickness, etc. of the waveguide plate. The pressurizing components on the same side are evenly spaced; the positions and quantities of the pressurizing components are adaptively adjusted according to the size and shape of the waveguide plate.

[0028] Preferably, it also includes a receiving seat, which is assembled by a combination of several receiving blocks; the receiving seat is arranged on the protrusion 11; the receiving block includes a mounting hole 31 and a second receiving block 32; the mounting hole 31 is arranged longitudinally with the protrusion 11; the second receiving block 32 is arranged at the top of the mounting hole 31 and is arranged transversely with the protrusion 11, and the second receiving block 32 is detachably installed with the mounting hole 31; the mounting hole 31 is a basic receiving seat, and the receiving seat is formed by a preset arrangement, and the waveguide plate is placed on the receiving seat composed of the mounting holes 31, and then the pressurizing component 20 is used to pressurize and tighten it; when the density between the mounting holes 31 is high and the height is low, and they cannot adapt, the second receiving block 32 is installed on the top of the mounting hole 31, and the second receiving block 32 and the mounting hole 31 are perpendicular to each other; the spacing between the second receiving blocks 32 is larger, which is more suitable for larger waveguide plates; this design enhances the stability of the fixture and ensures the accuracy and stability during the processing. The receiving seat can be a structure made of hard plastic or metal, which can provide sufficient supporting force.

[0029] Preferably, it also includes an adjustment mechanism, which includes a plurality of adjustment bases, and the adjustment bases include a first adjustment base 41 and a second adjustment base 42. The first adjustment base 41 and the second adjustment base 42 are used in pairs with the pressurizing component 20, and the first adjustment base 41 and the second adjustment base 42 respectively adjust the heights of different pressurizing components 20; different adjustment bases are selected to adapt the pressurizing component 20 according to their applicable heights.

[0030] Preferably, the pressurizing assembly 20 comprises a four-bar mechanism formed by connecting the first bar 21, the second bar 22, the third bar 23 and the fourth bar 24 in pairs; and the first bar 21, the second bar 22, the third bar 23 and the fourth bar 24 at the bottom of the pressurizing assembly 20 are provided with connecting holes 25 at both ends; the connecting holes 25 connecting the first bar 21, the second bar 22, the third bar 23 and the fourth bar 24 are connected by pins. The two connecting holes 25 of the first bar 21 are provided at one end, and the other end is a pressing handle 211; the pressing handle 211 is provided in a flat shape. The connecting hole 25 of the second bar 22 is provided at one end and is provided in an upper and lower position; the other end is provided with a through hole 221; a pressurizing rod 222 is installed in the through hole 221 through the stoppers 223 provided at the upper and lower ends of the through hole 221. One end of the pressurizing rod 222 is a pressurizing end; the pressurizing end is provided with a flexible pressurizing member 224. As part of the fixture, the main function of the pressurized end is to ensure that the surface of the workpiece in contact with the fixture during the clamping process is smooth and undamaged, while providing uniform clamping force. The role of these pressurized parts is to ensure that the surface of the workpiece in contact with the fixture is smooth and undamaged when clamping the antenna waveguide plate. Flexible parts are usually soft and elastic materials. Common choices include rubber gaskets. Rubber is a common flexible material with good elasticity and wear resistance. Rubber gaskets can be set on the contact surface of the fixture, which can effectively protect the surface of the workpiece and provide uniform clamping force; silicone gaskets. Silicone has high temperature resistance and chemical resistance, and may be a better choice in some special processing environments. Silicone gaskets also have good elasticity and softness, which can effectively protect the surface of the workpiece; foam gaskets. Foam materials usually have good softness and elasticity, can provide a slight cushioning effect, and are generally suitable for applications where the clamping force requirements are not too strict; rubber / silicone coatings. In addition to gaskets, a layer of rubber or silicone material can be coated on the contact surface of the fixture to achieve similar protection and cushioning effects. Preferably, we choose to use rubber gaskets, because rubber has good elasticity and wear resistance, can provide effective workpiece surface protection, and can provide uniform clamping force during the clamping process.

[0031] The connection holes 25 of the third rod 23 are arranged at the left and right ends and the bottom is a mounting seat 231. The outer periphery of the mounting seat 231 is provided with mounting holes 232, and the mounting holes 232 are used for matching and mounting with the receiving seat. The first rod 21 and the second rod 22 are provided with cavities inside, and limit springs are provided in the cavities; the first rod 21 and the second rod 22 set the four-bar mechanism to a fixed posture through the limit springs; the limit springs have a certain strength, so that they can complete a large number of bending and resetting work. This design can make the clamp more adaptable to antenna waveguide plates of different shapes. When the shape of the antenna waveguide plate is slightly irregular, the spring clamp can automatically adjust the clamping force according to the shape. The first rod 21 is lifted upwards and the second rod 22 is tilted in the direction close to the first rod 21; the four-rod mechanism composed of the first rod 21, the second rod 22, the third rod 23 and the fourth rod 24, the third rod 23 is a frame, the second rod 22 and the fourth rod 24 are connecting rods, and the first rod 21 is a connecting rod; they are combined together by pins; and the freedom generated by its active movement is limited by a limit spring; so that it can move only when an external force intervenes; by lifting the pressure handle 211 end of the first rod 21, under the action of the limit spring, the second rod 22 is also lifted and moves closer to the position of the first rod 21, at this time, the waveguide plate can be installed, and then the first rod 21 is released to complete the clamping of the waveguide plate at one position.

[0032] Each section of the receiving seat is provided with a pressurizing assembly 20, which is convenient for clamping the received waveguide plate part. Since the position of the received part has support from the receiving seat, the clamping here has a better clamping effect and is more stable; by clamping it at a separate and optional position through the pressurizing assembly 20 at each location, it is easier to obtain the desired clamping effect. The pressurizing assembly 20 uses a four-bar mechanism and a limit spring to fix the workpiece and provide appropriate clamping force. In addition to the pressurizing assembly 20, the following alternatives can also be considered: pneumatic clamps, which use air pressure to generate clamping force, usually controlled by a cylinder. This clamp can provide a large clamping force and can be adjusted as needed. Hydraulic clamps, hydraulic clamps use the hydraulic pressure generated by the hydraulic system to clamp the workpiece. They usually have the advantages of high clamping force and precise control, and are suitable for processing processes with high requirements for clamping force and position. Mechanical clamps, mechanical clamps usually generate clamping force through mechanical devices such as screws, handles or handwheels. They may not offer as much force and adjustment flexibility as pneumatic or hydraulic clamps, but in some cases they may be simpler, more economical, and easier to maintain. Compared with other clamping alternatives, spring clamps are relatively simple in structure, usually consisting of springs and fixing components, so they are easy to install and operate. They do not require the support of an external air source or hydraulic system, so they can be more flexibly applied in the clamping environment; compared with pneumatic clamps or hydraulic clamps, the manufacturing cost and maintenance cost of the pressurized assembly 20 are lower. This makes them a common choice in many factories, especially for applications that require a large number of clamping devices. And the pressurized assembly 20 is suitable for waveguides of various shapes and sizes because their clamping force can be adjusted by selecting the appropriate limit spring. The pressurized assembly 20 also has the characteristics of quick clamping and releasing, and the operation is simple and quick. This is very beneficial for waveguide processing that requires frequent workpiece replacement.

[0033] Preferably, both ends of the longer side of the base 10 are provided with a carrying handle 12, which further increases the convenience of operation. These carrying handles 12 can help users easily carry and manipulate the clamp. For example, when the user needs to move the clamp to a different location or store it, the carrying handle can provide additional convenience.

[0034] Example 2

[0035] Second, see Figures 1 to 4The embodiment of the utility model provides a processing device, including a processing fixture of a novel antenna waveguide plate as described in any of the above embodiments; the fixture uses a rubber gasket as a flexible pressure member 224, and the surface of the workpiece in contact with the fixture is smooth and undamaged, and provides a uniform clamping force. The elasticity and wear resistance of rubber make it a good choice, ensuring the stability and accuracy of the workpiece during the processing, while increasing the service life of the fixture, providing an efficient and reliable processing solution for production.

[0036] Example 3

[0037] See also Figures 1 to 4 The utility model provides a new antenna waveguide plate processing fixture and processing device thereof, which have the following beneficial effects: strong adaptability. The fixture is designed with a pressurizing component 20, which is arranged around the outer periphery of the protrusion 11 of the base 10, and fully covers the position where the waveguide plate is arranged on the base 10. The position, quantity and height of the pressurizing component 20 can be adaptively adjusted according to the preset intervals for various shapes of the antenna waveguide plate, and then the waveguide plate can be clamped, thereby improving the adaptability and flexibility of processing. High stability. By setting the receiving seat, the base 10 and the receiving seat are bridged, which effectively enhances the stability of the processing fixture. Through the adaptive selection of the two-layer receiving seat, the waveguide plate can be assembled more safely, so that it will not be damaged during processing due to unstable receiving conditions during processing, and the stability of the processing process is further guaranteed. The operation is easy and a detachable pressurizing component 20 is adopted, which is convenient for users to install and disassemble the clamp. At the same time, a sufficient number of pressurizing components 20 are set on each end and side. The number and spacing of clamps can be selected according to their own applications, providing a more convenient operation method, making the operation easier and more efficient.
