Description

Technical Field

[0001] The invention belongs to the technical field of phased array radar. Background Art

[0002] With the continuous development of phased array radar technology, active arrays with array-type multifunctional module structures have been widely used in phased array radars. The modules of this type of array mostly adopt a multifunctional integrated design and are directly connected to the antenna through a blind-plug electrical connector. At present, some multifunctional modules are larger than 1.5 meters in size and weigh more than 15 kg. In addition, the plug-in and pull-out force of the electrical connector is large, making it particularly difficult to disassemble and assemble large-sized modules. The disassembly and assembly process requires the coordinated operation of multiple people, and the risk factor is higher than that of small-sized modules. At the same time, large-sized modules are usually designed with two positioning guide pins. During the actual disassembly and assembly process, the module often tilts due to the asynchronous force on the guide pins on both sides, which can easily damage the slender guide pins on the blind-plug connector and even damage the inner core of the connector. Summary of the invention

[0003] In order to solve the problems in the background technology, the present invention proposes a high-precision large-size module synchronous installation device.

[0004] The high-precision large-size module synchronous installation device proposed by the present invention is implemented by the following technical solutions:

[0005] A high-precision large-size module synchronous installation device includes a slide rail and a push-and-pull mechanism; the slide rail is used for flipping and preliminary guiding and positioning of the large-size module, and the push-and-pull mechanism realizes synchronous and smooth plugging and pulling installation of the large-size module. The two parts are interconnected and used together to realize precise synchronous installation of the large-size module. The slide rail is designed with a waist-shaped hole guide groove structure that matches the module and a 90° limit flip groove structure that utilizes the module's gravity; the boost and pull mechanism includes a box, a rack pressure plate, a short gear shaft, a long gear shaft, a synchronous gear, a synchronous gear belt, a rolling bearing, a sleeve and a handle; the gear on the short gear shaft is connected to the rack pressure plate to form a gear rack transmission structure; the gear on the long gear shaft is connected to the rack pressure plate to form a gear rack transmission structure; shoulders are designed on both sides of the gear on the short gear shaft and the long gear shaft, the synchronous gear is installed through the shoulders and sleeves on the short gear shaft and the long gear shaft, the short gear shaft and the long gear shaft form a synchronous gear belt transmission structure through the synchronous gear and the synchronous gear belt, the rolling bearing is connected to the short gear shaft and the long gear shaft through the shoulders and sleeves and the bearing end cover on the box; the handle and the long gear shaft are connected through a key structure. The gear rack transmission structure uses the linear motion of the rack to drive the module to move forward and backward to achieve the boost and pull function; the synchronous gear belt transmission structure connects the gears of the gear rack structure to achieve gear rack synchronous transmission.

[0006] Furthermore, the minimum distance L1 between the center of the upper limit groove of the slide rail and the rack should be smaller than the distance L2 between the pin hole on the module and the end face of the module, to ensure that the module will not interfere with the rack.

[0007] Furthermore, the length of the gear transmission cooperation between the rack on the rack pressure plate and the gear on the gear shaft should be greater than the sliding value of the module from the boost starting point to the boost end point.

[0008] The invention proposes a high-precision large-size module synchronous installation device, which realizes the installation support and sliding rough guide of large-size modules, reduces the installation difficulty of large-size modules, and improves the safety during the installation of large-size modules. The boosting and pulling-out method provided by the device can overcome the large plug-in force and separation force of the electrical connector, and easily realize the blind plugging and separation of the module. At the same time, the synchronous design of the boosting and pulling-out in the device effectively ensures the synchronous blind plugging of the module electrical connector and reduces the damage rate of the electrical connector.

The gear on the short gear shaft 4 is connected to the rack pressure plate 3 to form a gear rack transmission, and the gear on the long gear shaft 5 is connected to the rack pressure plate 3 to form a gear rack transmission. Shoulders are designed on both sides of the gears on the short gear shaft 4 and the long gear shaft 5, respectively, the synchronous gear 6 is installed through the shoulders on the short gear shaft 4 and the long gear shaft 5 and the sleeve 9, the short gear shaft 4 and the long gear shaft 5 form a transmission connection through the synchronous gear 6 and the synchronous gear belt 7, and the rolling bearing 8 is connected to the short gear shaft 4 and the long gear shaft 5 through the shoulders and the sleeve 9 and the bearing end cover on the housing 2. The handle 10 and the long gear shaft 5 are connected by a key structure.

[0015] like Figure 1 As shown, in this embodiment, the slide rail 1 is installed on the rack 11. When the module 12 is installed, the module 12 is first connected to the bottom slide rail 1 of the rack 11, and the module 12 is connected to the top slide rail 1 of the rack 11 after rotating 90° around the slide rail limit groove. After the connection, the module 12 can slide along the waist-shaped slide groove of the slide rail 1 to achieve the support and forward and backward guided movement of the module 12. The minimum distance L1 between the center of the limit groove of the slide rail 1 and the rack 11 should be less than the distance L2 between the pin hole on the module 12 and the end face of the module 12 to ensure that the module 12 will not interfere with the rack 11.

[0016] like Figure 2 and Figure 3 As shown, the box 2 is installed on the rack 11, and the rack pressure plate 3 is installed on the module 12. Turn the handle 10 counterclockwise to drive the gear on the long gear shaft 5 and the synchronous gear 6 to rotate counterclockwise, and further drive the gear on the short gear shaft 4 to rotate counterclockwise synchronously through the synchronous gear belt 7. The gear drives the rack pressure plate 3 to move linearly to the left, pressing the module 12 to move to the left until the module 12 is pressed onto the rack 11, and the electrical connector on the module 12 is blindly plugged into the electrical connector on the backplane of the rack 11. Similarly, turn the handle 10 clockwise, similar transmission principle, the rack pressure plate 3 pulls the module 12 to move to the right, and the module 12 is disengaged from the rack 11, and the electrical connector on the module 12 is disengaged from the electrical connector on the backplane of the rack 11.
