The embodiment of the invention firstly provides a clamping device for machining a waveguide with wings. Referring to fig. 1, the apparatus may include: a base plate 104 and a plurality of platens 108; a plurality of mutually parallel T-shaped grooves 105 for placing the winged waveguide 101 are uniformly formed in the upper surface of the bottom plate 104, the main body part 102 of the winged waveguide 101 is positioned in the vertical groove 107 of the T-shaped groove 105, and the wing part 103 of the winged waveguide 101 is erected on a step formed by the horizontal groove 106 and the vertical groove 107 of the T-shaped groove 105; the pressing plates 108 are parallel to each other, detachably mounted on the bottom plate 104, and arranged parallel to the T-shaped groove 105, and are used for pressing the wing portions 103 of the winged waveguide 101; wherein the width of the horizontal groove 106 in the T-shaped groove 105 is 0-4 mm wider than the width of the wing part 103 of the winged waveguide 101, the depth is 1-2 mm smaller than the thickness of the wing part 103 of the winged waveguide 101, the width of the vertical groove 107 in the T-shaped groove 105 is 0-1 mm wider than the width of the main body part 102 of the winged waveguide 101, and the depth is 0-10 mm larger than the thickness of the main body part 102 of the winged waveguide 101 below the wing part 103; the thickness of the pressing plate 108 close to the winged waveguide 101 is smaller than the distance from the deepest slotted slot bottom of the winged waveguide 101 to the wing 103.
Through the processing and clamping device for the winged waveguide 101, on one hand, the processing and clamping device can clamp a plurality of winged waveguides 101 at one time, the flatness of the slotted surface of the winged waveguide 101 is good, precision compensation is not needed for measuring points, and the processing efficiency can be effectively improved. On the other hand, the wing part 103 of the winged waveguide 101 is pressed by the pressing plate 108, so that the main body 102 of the winged waveguide 101 is not damaged, the size of the inner cavity of the main body of the winged waveguide 101 is not changed, and the microwave performance index of the winged slot waveguide after processing is ensured.
Specifically, by forming a T-shaped groove 105 for placing the winged waveguide 101 on the bottom plate 104, the winged waveguide 101 can be placed in the T-shaped groove 105 for processing during processing, and deformation of the winged waveguide 101 in a direction perpendicular to the T-shaped groove 105 and parallel to the bottom plate 104 is subjected to certain constraint correction through constraint of the T-shaped groove 105; and then the pressing plate 108 is arranged, so that the pressing plate 108 presses the wing part 103 of the winged waveguide 101 along the longitudinal direction of the winged waveguide 101, and under the action of the pressing plate 108, the deformation of the winged waveguide 101 in the direction vertical to the base plate 104 is restrained and corrected, thereby not only improving the linearity of the winged waveguide 101, but also enabling the processing surface of the winged waveguide 101 to be on a horizontal plane as much as possible, and when in processing, the processing precision can be reached by one-time processing by directly cutting the processing surface by using a milling cutter as a reference, and the defect that under other clamping modes, the precision compensation needs to be carried out on a measuring point due to the fact that the processing surface of the waveguide is difficult to be ensured on a horizontal plane is solved.
