Description

Technical Field

[0001] The utility model relates to the field of mechanical tooling, in particular to a waveguide ridge quick clamping point hole device. Background Art

[0002] The waveguide ridge part is a key component in the transition antenna. Its main function is to adjust the reflected electromagnetic waves and plays a key role in the transition product. In the assembly of the transition antenna, high assembly accuracy is required to ensure that the waveguide ridge and the waveguide transition joint surface fit tightly without gaps and are in the center of the waveguide transition. Otherwise, if there are gaps on the joint surface and the symmetry is out of tolerance, electromagnetic waves will leak and affect the electrical performance.

[0003] In the current hole-dotting operation, the waveguide ridge and the transition waveguide are first repaired and fitted well, and then the waveguide ridge is positioned with a positioning block at the front end of the transition waveguide. A simple tooling is formed by adding a section of extended handle to the rear end of the transition waveguide using the cut surplus material to support the waveguide ridge. When this method is used to fix the waveguide ridge, the supporting area at the rear end of the waveguide ridge is small, and it is easy to shake during the hole-dotting operation, resulting in the position of the hole being offset, and the waveguide ridge yield is low. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a waveguide ridge quick clamping point hole device.

[0005] The purpose of the utility model is achieved through the following technical solutions: a waveguide ridge quick clamping point hole device, including a transition waveguide, a positioning core and a tightening component; the transition waveguide is provided with a through tube cavity for accommodating the waveguide ridge, the head end opening of the tube cavity is rectangular, and the tail end opening is circular; the head end of the positioning core is rectangular, and the tail end is circular, and corresponding to the size of the tube cavity, the head end of the positioning core is provided with a clamping part for clamping the waveguide ridge; the tightening component is provided on the positioning core and is used to tightly connect the positioning core with the transition waveguide. By providing a positioning core corresponding to the shape and size of the tube cavity and providing a clamping part on the positioning core, the waveguide ridge can be stably positioned, so that the waveguide ridge point hole position is accurate and the yield rate is improved.

[0006] In some embodiments, the positioning core includes a first positioning core and a second positioning core that are detachable and snap-fitted, and a gap between the front ends of the first positioning core and the second positioning core forms a clamping portion. By setting the positioning core as a split first positioning core and a split second positioning core, it is convenient to install the waveguide ridge into the clamping portion.

[0007] In some embodiments, at least two positioning pins are provided between the first positioning core and the second positioning core. Positioning pins are provided between the first positioning core and the second positioning core to ensure accurate position when the first positioning core and the second positioning core are buckled together to avoid position deviation.

[0008] In some embodiments, the fastening components are provided with at least two groups and are evenly arranged around the positioning core. A plurality of fastening components are evenly arranged on the positioning core so that when the fastening components connect the positioning core and the transition waveguide, the positioning core is evenly stressed to avoid deviation of the positioning core position due to uneven stress.

[0009] In some embodiments, a flange is provided at the tail end of the transition waveguide upper tube cavity, which facilitates the connection of the transition waveguide with other components and provides a force-bearing surface for the fastening assembly.

[0010] In some embodiments, the fastening assembly includes a mounting seat and a buckle, wherein the mounting seat is disposed on the positioning core, the buckle is hinged to the mounting seat, and the buckle is used to clamp the flange at the rear end of the tube cavity. The buckle ensures that the positioning core is installed in place in the tube cavity.

[0011] In some embodiments, the buckle is U-shaped, one end of which is hinged to the mounting seat, and the other end is clamped to the flange, and one end of the buckle clamping the flange is provided with a set screw, and one end of the set screw abuts the flange. In order to ensure that the positioning core is completely fitted with the lumen, a set screw is provided on the buckle, so that the set screw abuts the flange, and then the buckle generates an axial force on the positioning core, so that the positioning core is fitted with the lumen.

[0012] In some embodiments, a screw block is provided at the end of the set screw not contacting the flange, and the surface of the screw block is provided with knurling. The knurling on the surface of the screw block and the top block facilitates the operator to directly screw the set screw barehanded, which is convenient for quick clamping.

[0013] In some embodiments, a gasket is provided between the set screw and the flange to prevent the set screw from damaging the flange surface.

[0014] The utility model has the following advantages:

[0015] By setting a positioning core with a shape size consistent with the tube cavity, and setting a clamping part on the surface of the positioning core, after the waveguide ridge is installed on the clamping part, the positioning core is inserted into the tube cavity, so that the positioning core and the tube cavity are completely fitted. Since the opening at one end of the tube cavity is circular and the opening at the other end is rectangular, the positioning core is positioned in the circumferential and radial directions after being fully inserted into the tube cavity. With the help of the tightening component, the positioning core is axially positioned to achieve the effect of completely positioning the positioning core. When performing the hole-dotting operation on the waveguide ridge, the support is stable and no shaking occurs, thereby improving the yield rate of the waveguide ridge hole-dotting.

[0023] like Figure 1-Figure 4 As shown, a waveguide ridge quick clamping point hole device comprises a transition waveguide 1, a positioning core 2 and a tightening component 4; the transition waveguide 1 is provided with a through tube cavity 11 for accommodating the waveguide ridge 7, the head end opening of the tube cavity 11 is rectangular, and the tail end opening is circular; the head end of the positioning core 2 is rectangular, and the tail end is circular, and corresponding to the size of the tube cavity 11, the head end of the positioning core 2 is provided with a clamping portion 3 for clamping the waveguide ridge 7; the tightening component 4 is arranged on the positioning core 2 and is used to tightly connect the positioning core 2 with the transition waveguide 1.

[0024] In this embodiment, specifically, the lumen 11 is divided into two sections, including a cylindrical section and a conical section, wherein the large opening of the conical section is circular and connected to the cylindrical section, and the small opening of the conical section is rectangular. Accordingly, the head end of the positioning core 2 is a cone corresponding to the conical section of the lumen 11, and the tail end of the positioning core 2 is a cylinder corresponding to the cylindrical section of the lumen 11. Since the opening at one end of the conical section of the lumen 11 is circular and the opening at the other end is rectangular, not conical, therefore, when the head end of the positioning core 2 cooperates with the conical section of the lumen 11, the positioning core 2 is circumferentially positioned and will not rotate.

[0025] When using the device, the waveguide ridge 7 is installed into the clamping portion 3 at the head end of the positioning core 2, and then the positioning core 2 is inserted into the tube cavity 11. The head end of the positioning core 2 is circumferentially positioned by the cone section of the tube cavity 11, and then the positioning core 2 and the tube cavity 11 are tightly fitted through the tightening component 4, so that the positioning core 2 is positioned axially and radially. At this time, since the waveguide ridge 7 is installed in the positioning core 2, the waveguide ridge 7 and the transition waveguide 1 are completely positioned. When the hole-dotting work is performed, the waveguide ridge 7 will not shake, ensuring the accuracy of the hole-dotting position and improving the yield rate.

[0026] Preferably, the positioning core 2 includes a separable first positioning core 21 and a second positioning core 22 which are buckled together, and the gap between the front ends of the first positioning core 21 and the second positioning core 22 forms the clamping portion 3.

The thickness of the clamping part 3 corresponds to the thickness of the waveguide ridge 7. The positioning core 2 is set to a split form to facilitate the installation of the waveguide ridge 7 into the clamping part 3. When installing the waveguide ridge 7, first place the waveguide ridge 7 on the step of the first positioning core 21 or the second positioning core 22, and then buckle the second positioning core 22 and the first positioning core 21 to ensure that the waveguide ridge 7 is completely located in the clamping part 3 before inserting the positioning core 2 into the tube cavity 11.

In this embodiment, flanges 12 are provided at both the head end and the tail end of the transition waveguide 1 for connecting with other components, wherein the flange 12 at the tail end of the transition waveguide 1 also serves to provide a force-bearing surface for the fastening component 4.
