Abstract
Description
Technical Field
[0001] This utility model relates to a tool for assembling optoelectronic pods, specifically a double-rotating sleeve tool for installing inner and outer bearing pressure rings. Background Technology
[0002] The optoelectronic pod has azimuth and pitch axes and numerous moving parts. Therefore, during assembly, the fastening of parts on the inner and outer rings of the bearings can only be done after the bearings are fixed in place and allowed to rotate. During assembly, some parts on both the inner and outer rings are movable; when tightening the inner ring's retaining ring, the parts on the inner ring will rotate along with it, making it impossible to effectively tighten the retaining ring. Generally, assembly is done collaboratively by multiple people using various tools to fasten the bearing mounting parts and retaining rings. Therefore, each unit requires additional manpower during assembly, and the potential for errors during manual operation places higher demands on the skills and professionalism of the personnel.

[0025] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0026] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
[0027] As described in the background section, product assembly typically involves a multi-person collaborative process. Multiple people use various tools to tighten bearing mounting parts, pressure rings, and other components. Therefore, each product requires additional labor costs during assembly, and the potential for errors during manual operation places higher demands on the skills and professionalism of the personnel.
[0028] For the reasons mentioned above, such as Figures 1-11 As shown, this embodiment provides a double-screw socket tool for installing inner and outer bearing pressure rings, including a first socket wrench 100, a second socket wrench 200, an inner thread 101, an outer thread 201, an outer thread head 203, and an inner thread head 102;
[0029] The external screw 201 passes through the second socket wrench 200, the external screw head 203 is installed at the end of the external screw 201 and rotates with the external screw 201, and the external screw 201 is driven to rotate by the second socket wrench 200;
[0030] The inner thread 101 passes sequentially through the first socket wrench 100, the outer thread 201, and the outer thread head 203. The inner thread head 102 is mounted on the end of the inner thread 101 via a fixed limiting head 103 and rotates with the inner thread 101. The inner thread head 102 and the outer thread head 203 are coaxially mounted and rotate relative to each other. The inner thread 101 and the outer thread 201 rotate relative to each other and are driven to rotate by the first socket wrench. For example, the first socket wrench is a 13-16cm existing socket wrench, and the second socket wrench is a 17-19cm existing socket wrench.
[0031] The aforementioned technical features enable the installation of two mutually rotating parts by using two socket wrenches, one for fixing the bearing mounting parts and the other for tightening the bearing retaining ring on the parts, thereby enabling the installation of the bearing retaining ring while the parts are in motion.
[0032] like Figure 5 and Figure 8 As shown, during use, the inner and outer threaded heads are respectively engaged with the fixed shaft 302 and pressure ring 301 of the photoelectric pod shaft system component 300. Then, depending on the thread direction of the pressure ring, either the first or second socket wrench is rotated. During use, the first socket wrench drives the inner threaded rod to rotate, which in turn drives the fixed limit head to rotate, and then drives the inner threaded head to rotate. The inner threaded head drives or stabilizes the fixed shaft. During this process, the inner and outer threaded rods can rotate relative to each other, and the inner and outer threaded heads can also rotate relative to each other. When the second socket wrench rotates, it drives the outer threaded rod to rotate, which in turn drives the outer threaded head to rotate, and the outer threaded head drives or stabilizes the pressure ring.
[0033] To enable the socket wrench to drive the screw head to rotate, such as Figures 4-5 , Figure 7 , Figures 9-11 As shown, in one embodiment, the internal screw and the first socket wrench are driven by a polygonal surface engagement. The front end of the internal screw engages with the fixed limiting head through a polygonal surface engagement. The end of the internal screw and / or the fixed limiting head engages with the internal screw head through a polygonal surface engagement. The fixed limiting head 103 is fixedly connected to the internal screw 101 by a screw 104.
[0034] The external screw and the second socket wrench are driven by a polygonal surface engagement. The end of the external screw has a polygonal transmission part, and the external screw head has a transmission groove that matches the transmission part.
[0035] The first and second socket wrenches are positioned along the axis by the shoulders of the inner and outer screws. The outer screw head is axially limited by a limiting surface that engages with the end face of the inner screw head (close to the end face of the first socket wrench). Although the two surfaces are in contact with each other, relative rotation is possible.
[0036] The aforementioned technical features enable the transmission of torque between the socket wrench and the screw head. The torque transmission is achieved through the cooperation of polygonal surfaces. The cooperation of the multifaceted surfaces is the cooperation between the polygonal surface and the polygonal groove surface, thereby achieving the following rotation, that is, the transmission of torque.
[0037] To achieve relative rotation between the internal and external screws, such as Figure 7 , Figures 9-11 As shown, in one embodiment, the inner screw rod extends through a smooth section of the outer screw rod, and the outer screw rod has a through groove that matches the smooth section. The smooth section and the through groove are in clearance fit, allowing for relative rotation.
[0038] In order to enable transmission between the screw head and the pressure ring, such as Figure 4 As shown, in one embodiment, the ends of the external and internal screw heads have drive teeth that match the mounted component, which is the pressure ring or fixed shaft of the photoelectric pod shaft bearing; the external and internal screw heads are existing screw heads that can be adapted to the pressure ring.
[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
