[0002] Chinese patent document CN212134376U discloses a bending strength testing device for ceramic dielectric waveguide filters. To address the current market lack of devices for testing the bending strength of ceramic dielectric waveguide filters, which makes it difficult to directly assess structural strength, the device includes a bending strength testing main body with a connecting column at one end of its lower surface. Two safety plates are provided on one side of the lower surface of the main body. A bending strength testing base is provided on the lower surface of the connecting column, and four anti-slip support rods are provided on the lower surface of the base. Anti-slip support feet are provided below each of the four anti-slip support rods. A reinforcing block is provided at one end of the main body.

[0003] The aforementioned device contains four gripping parts, which means that when fixing the waveguide filter, it is usually necessary to use two hands or even multiple people to operate multiple discretely distributed gripping points simultaneously. The operation process is cumbersome and time-consuming, significantly reducing the detection efficiency. To address this, we propose a waveguide filter bending strength detection device.

[0027] The clamping mechanism 4 also includes a fixed block 46, a fixed rod 47, a movable piece 48, and a spring 49. Two sets of fixed blocks 46 are fixedly installed at the bottom of the support platform 2.

[0028] The bending mechanism 5 includes a testing machine 51, a hydraulic rod 52, a hanging plate 53, a rotating handle 54, a double-acting screw 55, T-shaped plates 56, and a protruding strip 57. The testing machine 51 is fixedly mounted on the top of the base 1. A hydraulic rod 52 is fixedly mounted on the testing machine 51. The free end of the hydraulic rod 52 passes through the testing machine 51 and is fixedly mounted on the hanging plate 53. A rotating handle 54 is rotatably mounted on one outer surface of the hanging plate 53. A groove is formed at the bottom of the hanging plate 53. A double-acting screw 55 is rotatably mounted between the inner walls of the two sides of the groove. The shaft of the rotating handle 54 is connected to the double-acting screw 55. Two sets of T-shaped plates 56 are threaded onto the double-acting screw 55. The vertical sections of both sets of T-shaped plates 56 are connected to the groove.

The installation position and bending position of the waveguide filter are confirmed by the linear laser module 6, slider 7, positioning piece 8 and scale 9, which ensures the effectiveness of the device and is conducive to the promotion and use of the device.

[0029] Working principle: First, adjust the positions of the two sets of positioning plates 8 by sliding the two sets of sliders 7 according to the size of the waveguide filter. Pull the connecting rod 44 located on the front side, which drives the corresponding clamping plate 45 to move forward and drives the corresponding toothed plate 41 to slide. Through the gear 42, it drives the other set of toothed plates 41 to slide in the opposite direction, i.e., backward, which in turn drives the other set of clamping plates 45 to slide backward, so that the two sets of clamping plates 45 separate. Then, place the waveguide filter to be tested on the support platform 2 and place it between the two sets of clamping plates 45, so that the waveguide filter is in contact with the two sets of positioning plates 8. When the two sets of toothed plates 41 slide, they will drive the two sets of movable plates 48 to move in various fixed positions. Slide and compress each spring 49 on rod 47. After releasing, the two sets of springs 49 rebound and cause the two sets of clamping plates 45 to clamp and fix the waveguide filter. After completion, move the positioning piece 8 to one side, and then rotate the handle 54 to drive the bidirectional lead screw 55 to rotate, which drives the two sets of T-shaped plates 56 to move towards each other to adjust the spacing. The position of the scale 9 is indicated by the two sets of linear laser modules 6, so that the two sets of convex strips 57 are adjusted to the bending position of the waveguide filter. Then, control the free end of the hydraulic rod 52 to extend, drive the hanging plate 53 to move down, and the two sets of convex strips 57 squeeze the waveguide filter to bend. The user can observe the data through the control screen 11.
