Description

Technical Field

[0001] The utility model belongs to the technical field of insulator installation, and relates to a tool used for insulator assembly. Background Art

[0002] With the rapid development of aviation and aerospace engineering, phased array antennas are becoming more and more widely used. Among them, a single oscillator has a simple structure, consisting of an inner conductor, an insulator, and an outer shell. However, due to the structural characteristics of the antenna itself, the inner and outer conductors need to be connected, and the insulator needs to be slotted to allow the inner conductor to connect with the outer shell.

[0003] Since the insulators are coaxial and are directly assembled during assembly, there is a possibility that the insulator slots and the shell slots may not be aligned, resulting in the inner conductor being unable to be installed in place, low yield rate, and increased production costs. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that when the insulator is reinstalled, the insulator slot is not aligned with the shell slot, resulting in the inability to install the inner conductor in place, and provides a tool for assembling the insulator.

[0008] An insulator is arranged inside the vibrator outer conductor, and the end of the insulator contacts the adjacent end of the base. A protrusion is arranged on the upper end of the base, and a clearance groove corresponding to the protrusion is opened at the end of the base, and the protrusion can be inserted into the clearance groove.

[0009] The further improvement of the utility model is:

[0010] The positioning portion includes positioning blocks distributed circumferentially along the end of the vibrator outer conductor.

[0011] There are four positioning blocks.

[0012] The base includes a limiting section and a supporting section;

[0013] Through holes corresponding to the structures of the limiting section and the supporting section are respectively opened inside the tooling shell. After the limiting section is inserted into the corresponding through hole, the through hole can circumferentially limit the limiting section;

[0014] The end of the supporting section away from the limiting section abuts against the elastic component.

[0015] The cross section of the limiting section is a non-circular structure.

[0016] The cross section of the limiting section is a quadrilateral, and the quadrilateral includes two symmetrically distributed arc sides and two symmetrically distributed straight sides.

[0017] The elastic component is a spring, and a fixing plug is arranged at one end of the spring away from the base.

[0018] The fixing plug is a nut.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The utility model discloses a tool for assembling an insulator, comprising a tool shell capable of limiting the position of an outer conductor of a vibrator, the outer conductor of the vibrator is placed at the upper end of the tool shell, and when a limiting groove on the tool shell is matched with a positioning part on the outer conductor of the vibrator, the first step of positioning of the outer conductor of the vibrator is met, and when the insulator is installed, the end of the insulator contacts the end of the base that is close to each other, and the protrusion is further matched with the giving way groove, and the protrusion limits the installation position of the insulator to avoid the circumferential rotation of the insulator, and under the matching constraint of the tool shell and the base, the insulator and the outer conductor of the vibrator are aligned and installed, and in combination with an elastic component, a force application space for pressing the insulator downward is reserved during assembly, and downward force is applied to ensure that the insulator and the installation position inside the tool shell are in place, and the installation tool can realize the assembly alignment of the insulator and the outer conductor of the vibrator, will not affect the subsequent installation of the inner conductor, and improves the yield rate.

[0021] Furthermore, in this embodiment, the positioning portion includes positioning blocks distributed circumferentially along the end of the vibrator outer conductor, thereby improving the constraint effect on the circumferential installation position of the vibrator outer conductor.

[0022] Furthermore, in this embodiment, the through hole inside the tooling shell can limit the circumferential rotation of the limit section, so that when the base is installed inside the tooling shell, it can only be installed according to a preset angle, thereby improving the accuracy of the installation position constraint during the subsequent installation of the insulator.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0043] The utility model is further described in detail below with reference to the accompanying drawings:

[0044] See also Figures 1 to 5The present embodiment discloses a tool for assembling an insulator, comprising a tool shell 1, wherein a base 2 and an elastic component 3 are sequentially arranged inside the tool shell 1 from top to bottom; during installation, the upper end of the tool shell 1 is matched and connected to the vibrator outer conductor 4, a positioning groove 8 is provided at the upper end of the tool shell 1, and a positioning portion matching the positioning groove 8 is provided at the end of the vibrator outer conductor 4 matching with the tool shell 1; an insulator 5 is arranged inside the vibrator outer conductor 4, and an end of the insulator 5 contacts with an end of the base 2 that is close to the vibrator outer conductor 4; a protrusion 6 is arranged at the upper end of the base 2, and a clearance groove 7 corresponding to the protrusion 6 is provided at the end of the base 2, and the protrusion 6 can be inserted into the clearance groove 7.

[0045] See also Figure 4 and Fig. 9 Furthermore, in this embodiment, the positioning groove 8 is a petal groove structure, and the positioning portion includes positioning blocks 9 distributed circumferentially along the end of the vibrator outer conductor 4. There are four positioning blocks 9, and there are four positioning grooves 8 distributed circumferentially at the end of the tooling housing 1. During installation, the four positioning blocks 9 are respectively inserted into the corresponding positioning grooves 8.

[0046] See also Figure 6 to Figure 7 Furthermore, in this embodiment, the base 2 includes a limiting segment 10 and a supporting segment 11. The base 2 includes the limiting segment 10 and the supporting segment 11, which are assembled in the through hole inside the tooling shell 1. The diameter of the limiting segment 10 is smaller than the diameter of the supporting segment 11. The cross-section of the limiting segment 10 is a non-circular structure, specifically an anisotropic structure. This embodiment discloses a structure with a cross-section of a quadrilateral, including two symmetrical arc sides and two symmetrically distributed straight sides. The through hole structure corresponding to the limiting segment 10 in the tooling shell 1 is the same as the limiting segment 10. When the limiting segment 10 extends into the interior, the circumferential direction of the limiting segment 10 can be restricted, so that the entire base 2 can only be assembled in the direction of the constraint.

[0047] At the same time, the protrusion 6 is located at the end of the limiting section 10. After the insulator 5 is placed inside the tool housing 1, the clearance groove 7 is ensured to correspond to the protrusion 6, so that the installation position of the insulator can be constrained.

[0048] Furthermore, in this embodiment, the elastic component 3 is a spring, and the spring 3 is arranged at one end of the base 2 away from the insulator 5. The lower end of the spring is equipped with a fixing plug 12, and the fixing plug 12 enables the base 2 and the spring to be stably assembled in the tooling housing 1. When it is necessary to ensure that the insulator is axially installed in place, when the groove 7 is engaged with the protrusion 6, the insulator 5 can be pressed downward. At this time, the base 2 is forced to move downward, further squeezing the spring. When the insulator 5 is axially installed in place, the pressing is stopped, the spring rebounds, and the base 2 is reset.

[0049] Furthermore, in this embodiment, the fixing plug 12 is a nut.

[0050] Furthermore, the installation method of the tooling disclosed in this embodiment is:

[0051] Place the vibrator outer conductor 4 on the tool housing 1, and insert the positioning block 9 on the upper end of the tool housing 1 into the positioning groove 8 to complete the direction positioning of the vibrator outer conductor 4;

[0052] Put the insulator 5 into the vibrator outer conductor 4. When the lower end of the insulator 5 contacts the upper end of the base 2, the protrusion 6 is inserted into the clearance groove 7. At this time, the positions of the insulator 5 and the vibrator outer conductor 4 are aligned.

[0053] With the cooperation of the spring, the insulator 5 is pressed downwards and pressed into a corresponding position in the vibrator outer conductor 4, and the insulator 5 is installed in place.

[0054] The tooling can align the insulator's clearance slot with the outer shell slot to ensure that the inner conductor can be installed in place. It has been verified by product assembly and the product qualification rate is 100%.

[0055] See also Figures 8 to 12 After the vibrator outer conductor 4 and the insulator 5 are installed in place, the tooling is removed and the inner conductor 13 is installed in the insulator 5. At this time, the inner conductor limiting portion 14 is inserted into the clearance groove 7 to complete the assembly of the vibrator.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
