Description

Technical Field

[0001] The invention relates to the technical field of circulator assembly and processing, and in particular to a simple assembly tool for a dielectric sleeve and an inner conductor of a circulator isolator. Background Art

[0002] At present, the communication industry needs to use surface-mount circulators and isolators. The current structures of these two products use two parts: inner conductors and dielectric sleeves. Surface-mount circulators and isolators need to assemble these two parts during the production and assembly process. Since the sizes of these two parts are small, the inner conductor size is about 0.4 mm (diameter) × 1 mm (length), and the dielectric sleeve size is 1 mm (diameter) × 1 mm (length), manual direct assembly is very difficult and has low reliability. At present, it takes at least 5 seconds to manually assemble one piece, and surface-mount circulator / isolator products are interference fit. Almost one of these products needs to be installed with three dielectric sleeves, inner conductors or their components. Manual assembly requires pressing three times / product, which takes at least 15 seconds / piece. The manual efficiency is low, so tooling has to be used at this time. However, there are no reports or applications of such assembly tooling. Summary of the invention

[0007] As a further preferred technical solution: the positioning shaft includes a dielectric sleeve / inner conductor positioning hole, a spring guide column positioning hole, a product positioning hole, an anti-rotation plate limiting groove, a guide cylinder and a screw hole, wherein a ejector pin is inserted into the dielectric sleeve / inner conductor positioning hole of the structure, and the dielectric sleeve and the inner conductor are placed in the top of the hole; the spring guide column is pressed into the spring guide column positioning hole by interference fit; the shape of the product positioning hole is the same as that of the product, and is used for positioning the surface-mounted circulator / isolator product; the anti-rotation plate limiting groove just matches the boss of the anti-rotation plate; the positioning shaft and the anti-rotation plate are locked by passing screw C through the screw hole and locking it into the screw hole; the guide cylinder is inserted into the linear bearing, and slides axially smoothly under the guiding action of the linear bearing, and cooperates with the anti-rotation plate to prevent rotation.

[0008] As a further preferred technical solution: the ejector pin comprises a positioning cylinder, a flat top surface, a concave top surface, a bottom plane and an upper cylindrical surface, wherein the positioning cylinder is used to penetrate into the corresponding hole of the ejector pin pressure ring for precise positioning; the flat top surface is used to independently perform ejection on the dielectric sleeve and the inner conductor; the concave top surface avoids the large head of the inner conductor through the groove, and the outer ring presses on the dielectric sleeve to provide ejection force; the bottom plane presses on the plane corresponding to the fixed sleeve to prevent the ejector pin from moving axially; the upper cylindrical surface penetrates into the dielectric sleeve / inner conductor positioning hole to prevent the ejector pin from bending due to radial external force.

[0009] The tooling of the present invention can be used to conveniently, quickly and reliably assemble the inner conductor and the dielectric sleeve into place.

[0010] Compared with the prior art, the advantages of the present invention are as follows: the surface-mount circulator / isolator product is an interference fit, and almost one product of this type needs to be installed with three dielectric sleeves, inner conductors or their components. Manual assembly requires pressing three times / product, which takes at least 15 seconds / product; while the assembly tool of the present invention can assemble the dielectric sleeve, inner conductor or its components of the surface-mount circulator / isolator into place at one time, that is, the assembly method of the present invention requires pressing once / product, which takes 7.5 seconds / product, and the assembly efficiency is improved by at least 1 times; moreover, the tooling of the present invention has a simple structure, low cost, high reliability, and low labor intensity of manual operation.

A vertical downward external force is applied to the top of the product 15 by a manual press or an automatic manipulator to overcome the elastic force of the cylindrical spring 7, and the positioning shaft 12 moves downward steadily and linearly in the linear bearing 4. At this time, the parts connected to the fixed sleeve 3 remain stationary, and the inner conductor 15-1 or the dielectric ring 15-2 also remain stationary, but the product 15 is moving downward, and continues to press down until the positioning shaft 12 contacts the top of the bolt 10, and the inner conductor 15-1 or the dielectric ring 15-2 is pressed into the hole 15-3. When the pressure applied to the product is removed, the mechanism is reset under the action of the cylindrical spring 7, and the product is removed, and the action ends. The spring guide post 8 guides the spring, and the combination of the nut 9 and the bolt 10 can adjust the depth of the inner conductor 15-1 or the dielectric ring 15-2. The outer surface of the fixing sleeve 3 has a mesh pattern, which can prevent slipping during manual operation. This mechanism can cooperate with automation to achieve the assembly of the dielectric sleeve and the inner conductor of the product in place at one time.
