Description

Technical Field

[0001] This utility model relates to the field of aerospace test and launch technology, and in particular to a tooling for a rocket battery installation auxiliary device. Background Technology

[0002] In recent years, with the continuous development of my country's aerospace industry, launch site testing and operation work has become increasingly demanding. Rockets are high-value aerospace products, and any errors in onboard operations can cause huge, even irreparable, losses. Therefore, there are strict standards and requirements for the professional level and practical skills of personnel in these positions.

[0003] Rocket batteries are essential components of the rocket's structure, installed in various rocket sections. Their primary function is to power the rocket's systems and onboard instruments, making them a crucial part of the rocket's power-on testing and pre-launch preparations. Currently, rocket battery installation in space testing and launch procedures is mainly done by manual handling by personnel. However, the significant weight of most rocket batteries and the limited operating space within the rocket compartment present considerable difficulties and challenges for their transport and installation, specifically in the following ways:

[0004] 1. Battery installation typically requires two people. The battery handler removes the rocket battery from the product box and hands it to the hatch operator. During the handover process, there is a safety risk that the rocket battery may fall due to unclear communication during the exchange of passwords.

[0005] 2. During battery handling, due to the relatively heavy weight of the batteries (large batteries weighing nearly 25kg), the large distance between the rocket body and the platform, and the unevenness of the platform, operators may fall if they are not careful, posing a safety hazard of batteries falling.

[0006] 3. After manually handling rocket batteries for a period of time, operators experience significant physical exertion, making it increasingly difficult to adjust the batteries and battery bases at the rocket hatch, which greatly affects the efficiency of battery installation.

[0007] Therefore, in order to solve the problems of relying on manual labor, long assembly time, and complex installation procedures and operations in the current rocket battery installation, it is urgent to design a practical auxiliary tooling for rocket battery installation.

[0016] The movable tray 3 is U-shaped and is mainly used to hold batteries. Four cylindrical tray sliders 2 are connected to the four corners of the lower surface of the movable tray 3. The two cylindrical tray sliders 2 on the left are used to connect to the telescopic guide rail 7, and the two tray sliders 2 on the right are used to connect to the thin cylindrical guide rail of the fixed guide rail 1.

[0017] Furthermore, the movable tray is corrugated to prevent the battery from moving back and forth when placed on the base plate, thus ensuring battery safety.

[0018] Furthermore, the movable tray 3 includes a base plate and two side baffles, with the baffles being 4-6cm high, matching the height of the battery base.

[0019] Furthermore, the fixed slider 4 is a cylindrical ball slider, and the telescopic guide rail 7 is connected to the fixed slider 4 by a fitting method.

[0020] Furthermore, the base, front baffle, and movable support plate are made of bearing steel.

Detailed implementation method:

[0039] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0040] Figure 1 The environment inside the rocket cabin is described. For example... Figures 2 to 4 As shown, a rocket battery installation auxiliary tooling includes a fixed base 1, a tray slider 2, a movable tray 3, a fixed slider 4, a locking jaw 5, a fixing pin 6, a connecting rod 9, a telescopic guide rail 7, a front baffle 8, and a guide rail groove 10. The telescopic guide rail 7 is connected to the tray slider 2 by a ball-bearing slider fitting connection, and the connection between the fixed guide rail 1 and the locking jaw 5 is a threaded fastening method.

[0041] The fixed base is rectangular in shape and is the main component and load-bearing structure of the entire fixture. Two parallel guide grooves 10 are formed on the upper surface of the fixed base to facilitate the movement of the movable pallet 3. The connecting rod 9 is secured to the lower right end of the fixed base 1 with screws.

[0042] The connecting rod 9 is machined from cylindrical bearing steel of a specific diameter and is connected to the ends of the two telescopic guide rails 7 by screws, thus fixing the width of the telescopic guide rails 7. Two thin cylindrical rods are mounted on the connecting rod 9.

[0043] The telescopic rods are mounted on these two cylindrical guide rails. Two fixed sliders 4, connecting to the telescopic guide rails 7, are installed on the left end face of the fixed base. These two fixed sliders 4 play a crucial supporting role during the movement of the battery on the pallet. The two telescopic rods are mounted on the fixed guide rails, and fixing pins are installed in the fixing slider holes on the left front side of the base. These fixing pins lock the telescopic guide rails, preventing wobbling of the telescopic rods and improving their rigidity. The fixed base has oblong holes on both the front and rear sides for inspecting the appearance of the telescopic guide rails 7 and facilitating maintenance. The lower surface of the fixed base is connected to locking jaws via screws. The fixed base 1 is connected to the lower edge of the rocket battery compartment opening via locking jaws 5 and secured by set screws on the locking jaws 5. The threaded holes at the mounting points of the fixed base 1 and the locking jaws 5 are the same size, facilitating screw tightening.

[0044] The telescopic guide rail 7 consists of two long cylindrical rods, which are fitted onto two thin cylindrical rods on the fixed base 1, providing auxiliary support and spatial expansion. The telescopic guide rail has a diameter of 20 mm and is made of bearing steel. Designed and calculated, it can support a maximum product weight of 50 kg, enabling the handling of heavy rocket batteries and ensuring the support strength of the auxiliary tooling. In actual operation, the telescopic length of the guide rail is flexibly adjusted according to the battery installation distance. Once extended to the desired length, the far end of the telescopic guide rail rests on the base where the battery needs to be installed, effectively bridging the rocket body and the battery installation location. The telescopic guide rail 7 is then locked with a fixing pin to prevent swaying and improve its rigidity. The front baffle is made of a rectangular bearing steel plate of a certain length. A front baffle 8 is installed at the front end of the telescopic guide rail 7, acting as a limit to prevent the moving tray 3 from detaching from the telescopic guide rail and protecting the battery on the moving tray. The telescopic guide rail and the front baffle are connected by screws.

[0045] The movable tray 3 is U-shaped and is mainly used to hold batteries. It has a certain height and includes a base plate and two side panels. The height of the side panels is 4-6cm, which matches the height of the battery base.

[0046] The pallet slider is cylindrical, and the diameter of the pallet slider slot matches the diameter of the guide rail. Four cylindrical pallet sliders 2 are connected to the four corner points on its lower surface. The two cylindrical pallet sliders 2 on the left are used to connect to the telescopic guide rail 7 and fit onto it; the two pallet sliders 2 on the right are used to connect to the thin cylindrical guide rail of the fixed base 1. Preferably, the moving pallet of the battery installation auxiliary tooling is corrugated to prevent the battery from moving back and forth when placed on the base plate, ensuring battery safety.

[0047] The width of the connection between the two guide rails is the same as the width of the rocket battery base inside the cabin, and the thread size of the guide rail matches the thread size of the slider's thread hole.

[0048] The telescopic guide rail 7 can extend and retract freely relative to the fixed guide rail 1. After it is extended and locked in place, the movable tray 3 can move freely on the fixed base 1 and the telescopic guide rail 7. Through the cooperation of these two movable pairs, the battery to be installed can be transported to the given position.

[0049] A battery installation auxiliary tooling adopts a quick installation structure, which can be operated with only a general flathead or Phillips screwdriver. The connection is simple and the whole structure is easy to use.

[0050] The front baffle, base, and movable support plate are made of bearing steel, while the guide rails and sliders are also made of bearing steel.

[0051] The fixed slider 4 is a cylindrical ball bearing slider. The telescopic guide rail 7 is connected to the fixed slider 4 by a fitting method, and the diameter of the circular hole of the fixed slider 4 matches the diameter of the telescopic guide rail 7. The fixed slider 4 is installed on both sides of the front end of the fixed base 1 and is used for connecting and fixing the telescopic guide rail 7 to the fixed base 1.

[0052] The locking jaws consist of fixed jaws, movable jaws, a lead screw and nut, and a handle. They are used to rotate the lead screw. The locking jaws are connected to the guide rail by screw fastening, which allows the operator to control the clamping and loosening of the jaws. They are used to fix the guide rail to the hatch.
