Embodiment 1

[0053] like Figure 1-Figure 6 As shown, a radiation unit matching block positioning mechanism in this embodiment includes a tooling frame 401 , a first clamping cylinder 402 and a first pneumatic clamping jaw 403 , and the first clamping cylinder 402 is installed on the tooling frame 401 and its driving end is connected to and drives two first pneumatic clamping jaws 403 to open and close. After the claws 403 are closed, a matching block holding hole 404 for holding the matching block 102 is formed.

[0054] In this embodiment, the first clamping cylinder 403 is used to drive the first pneumatic clamping jaw 402 to clamp the matching block 102, and when the clamping block 102 extends into the space between the upper part of the tooling frame 401 and the first pneumatic clamping jaw 402, The first clamping cylinder 403 drives the first pneumatic clamping jaw 402 to release the matching block 102 , so that the matching block 102 falls into the matching block limiting groove 20...

Embodiment 2

[0056] like Figure 1-Figure 6 As shown, a radiation unit matching block positioning mechanism in this embodiment includes a tooling frame 401 , a first clamping cylinder 402 and a first pneumatic clamping jaw 403 , and the first clamping cylinder 402 is installed on the tooling frame 401 and its driving end is connected to and drives two first pneumatic clamping jaws 403 to open and close. After the claws 403 are closed, a matching block holding hole 404 for holding the matching block 102 is formed.

[0057] In this embodiment, the first clamping cylinder 403 is used to drive the first pneumatic clamping jaw 402 to clamp the matching block 102, and when the clamping block 102 extends into the space between the upper part of the tooling frame 401 and the first pneumatic clamping jaw 402, The first clamping cylinder 403 drives the first pneumatic clamping jaw 402 to release the matching block 102 , so that the matching block 102 falls into the matching block limiting groove 20...

Embodiment 3

[0067] like Figure 13 As shown, a radiation unit matching block assembling device in this embodiment includes a matching block fixture 200, an assembling jaw 206, a radiation unit fixture 300, and the positioning mechanism 400 described in Embodiment 1 or Embodiment 2. The matching block One end of the fixture 200 is provided with the matching block limiting slot 201 , and the assembling jaw 206 is used to clamp the matching block 102 and put it into the matching block limiting slot 201 ; the radiation unit fixture 300 is provided with an internal There is an elastic pin 301, and a matching block limiting slot 201 is provided at a position near the end of the matching block fixture 200; wherein, when the matching block fixture 200 drives the matching block 102 to extend into the radiation unit 100, the The elastic pin 301 in the radiation unit fixture 200 extends into the matching block limiting groove 201 and abuts one end of the matching block 102 .

Abstract

The invention relates to a radiating unit matching block positioning mechanism, an assembling device and a method. The positioning mechanism comprises a tooling frame, a first clamping cylinder and a first pneumatic clamping jaw, wherein the first clamping cylinder is installed on the tooling frame and Its driving end is connected to and drives the opening and closing of two first pneumatic clamping jaws. The first pneumatic clamping jaws are located above the tooling frame and are spaced apart from the tooling frame. After the two first pneumatic clamping jaws are closed, a Matching block holding hole for holding matching block. The invention adopts the first clamping cylinder to drive the first pneumatic clamping claw to clamp the matching block, and when the matching block clamp extends into the interval between the upper part of the tooling frame and the first pneumatic clamping claw, the first clamping cylinder drives the first pneumatic clamping claw. A pneumatic gripper releases the matching block so that the matching block falls into the matching block limiting groove of the matching block fixture.

Description

technical field [0001] The invention relates to the related technical field of radiating unit matching block assembly, in particular to a radiation unit matching block positioning mechanism, an assembling device and a method. Background technique [0002] In a typical antenna radiating unit, the matching block is installed on the plane of the sidewall of the waveguide inside the cavity. The length and width of the waveguide port are small, and two screws are used for positioning and fastening. During the installation and adjustment process, it is necessary to ensure that the matching block and the horn cavity are The dimensional accuracy of the preset position of the bottom flange needs to be tested after assembly. The assembly accuracy and consistency of the matching block directly affect the pass rate of the electrical performance index test of the radiation unit. [0003] At present, due to the narrow operating space, the structure of the baffle at the mouth edge and the ...
