Problems solved by technology

At present, it is difficult to ensure the offset of the central conductor and microwave ferrite in the production process of the isolator. There are two methods: one is visual positioning, and the other is fixture positioning. Visual positioning refers to the center conductor, microwave ferrite The positioning of other parts depends entirely on the observation of human eyes. This positioning method has large errors, poor consistency, very low efficiency, low production pass rate, high product scrap rate, and increased cost.
Fixture positioning refers to the use of fixtures to ensure that the circular cavity of the shell and the center conductor have the same coaxiality, and the pins of the fixture are manually adjusted to position the microwave ferrite; therefore, the alignment of the center conductor and the microwave ferrite is actually still Rely on vision; this positioning is better than visual positioning, but the consistency is still relatively poor, and the production efficiency is still relatively low

Embodiment Construction

[0013] The invention designs a positioning and assembling fixture, which can precisely center, locate and fasten the central conductor and the microwave ferrite.

[0014] like figure 1 The assembly device of the microwave isolator shown includes a workbench 7 and a pressing mechanism 3, side plates are arranged at the front and rear ends of the workbench 7, the workbench 7 is supported by the front and rear side plates, and the central part of the workbench 7 is arranged laterally. The central large round guide groove 1, the auxiliary small round guide groove 2 is arranged laterally on the left and right sides of the central large round guide groove 1, and the threaded holes are arranged horizontally on the front side plate or the rear side plate, and the pressing mechanism 3 passes through the side plate. The transverse threaded hole constitutes a screw transmission pair, which moves along the direction of the large circular guide groove in the center, and a buffer protection...

Abstract

The invention provides an assembling device of a microwave isolator. The assembling device comprises a workbench and pressing mechanisms. The assembling device is characterized in that side plates are arranged on the front and back ends of the workbench, the workbench is supported by the front and back side plates, a central great-circle guide slot is arranged in the central part of the workbench transversely, auxiliary small-circle guide slots are arranged on the left and right sides of the central great-circle guide slot transversely, screwed holes are arranged on the front or back side plate transversely, and the pressing mechanisms penetrate through the transverse screwed holes of the side plate to form a screw transmission pair which can move along the direction of the central great-circle guide slot. The centring, positioning and fastening of a central conductor and a microwave ferrite are realized, and the electric performance parameters of the microwave isolator are increased. Dozens of central conductors and microwave ferrite components can be bound once so that the centring accuracy and positioning accuracy of the microwave isolator are increased significantly, the one-time pass rate is greatly improved, the assembly time is significantly shortened, the cost is reduced, the consistency of the production is greatly improved, and the assembling device is in particular applicable to the mass production of microwave isolators.

Description

technical field [0001] The invention relates to an assembly device of a microwave isolator, belonging to the technical field of wireless communication. Background technique [0002] The working frequency of microwave isolators used in the field of wireless communication is generally 300-5000 MHz. High-frequency isolators are very sensitive to the accuracy of component assembly, especially the alignment, positioning and tightening of the center conductor and the microwave ferrite. It has a great influence on the electrical performance parameters of the isolator. Therefore, when the isolator is produced and assembled, the positional deviation of the center conductor and the microwave ferrite is required to be very small. At present, the positioning method of the center conductor and the microwave ferrite in the isolator production process is difficult to ensure the offset. There are two methods: one is visual positioning, and the other is fixture positioning. Visual positioni...
