Description

Technical Field

[0001] This invention relates to the technical field of carbon fiber multi-port joint grinding devices, specifically a grinding device and method for a rotary sleeve of carbon fiber multi-port joints. Background Technology

[0002] In the field of aerospace satellite technology, composite material truss structures play a crucial role, and carbon fiber multi-port joints, as key components, have a profound impact on the operation and functionality of the entire satellite. With the continuous development of aerospace technology, the performance requirements for satellites are increasing. Satellites need to possess higher reliability, longer service life, and stronger environmental adaptability. Composite material truss structures, due to their lightweight and high strength, have become an ideal choice to meet these requirements. Compared to traditional metal structures, composite material truss structures can reduce satellite weight while maintaining good structural strength, helping to reduce launch costs and improve the overall performance of the satellite.

[0003] Carbon fiber multi-port joints, as core connecting components of satellite composite truss structures, are responsible for connecting various truss members together to form a stable structural system. Their performance directly affects the stability and reliability of the entire truss structure. However, the manufacturing and processing of carbon fiber multi-port joints currently faces numerous challenges. In the grinding process of carbon fiber multi-port joints, manual grinding is not only inefficient but also difficult to guarantee precision, resulting in significant differences in size and surface quality between different joints, affecting the assembly accuracy and mechanical performance consistency of the entire truss structure. Simultaneously, the large amount of dust generated by manual grinding not only threatens the health of operators but also causes serious pollution to the production environment, increasing environmental costs and safety hazards in the production process.

[0004] Traditional manual grinding methods have become a bottleneck restricting the efficiency of satellite truss bonding development, necessitating the introduction of new devices and methods in the assembly process. To address this, we provide a rotary sleeve grinding device and method for carbon fiber multi-port joints. Summary of the Invention

[0005] The purpose of this invention is to provide a grinding device and method for a carbon fiber multi-port joint rotary sleeve, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grinding device and method for a carbon fiber multi-port connector using a rotary sleeve. The device is characterized by comprising: a dust collection platform, a control button box, a rotatable adsorption turntable, an electric pistol drill, a rotary sleeve assembly, and a carbon fiber multi-port connector. The dust collection platform is provided with a dust collection port and a threaded interface for fixing the control button box and the rotatable adsorption turntable. The control button box is used to control the normal operation and stop of the device. The rotatable adsorption turntable is used to adsorb and fix the carbon fiber multi-port connector and control the rotation angle. The electric pistol drill is used to clamp the rotary sleeve assembly, and the rotary sleeve assembly is used to grind the carbon fiber multi-port connector.

[0007] As a preferred embodiment, the carbon fiber multi-port joint rotary sleeve grinding device is characterized in that the control button box includes an emergency stop button, a pneumatic adsorption motor start button, a pneumatic adsorption motor stop button, a rotary stepper motor start button, and a rotary stepper motor stop button, which are used to control the normal operation and stop of the device.

[0008] As a preferred embodiment, the rotary sleeve grinding device for carbon fiber multi-port joints is characterized in that the rotatable adsorption turntable includes a rotary stepper motor, a coupling, a pneumatic adsorption motor, a turntable, and an adsorption port for adsorbing carbon fiber multi-port joints and controlling the rotation angle.

[0009] As a preferred embodiment, the carbon fiber multi-port joint rotary sleeve grinding device is characterized in that the electric pistol drill includes a drill chuck, a speed switch, a motor, a motor start / stop switch, and a removable battery for connecting the rotary sleeve assembly.

[0010] As a preferred embodiment, the rotary sleeve grinding device for carbon fiber multi-port joints is characterized in that the rotary sleeve assembly includes a locking sleeve, a locking adjusting screw, a clamping ring, a clamping groove, a rotary sleeve handle, a clamping slot, an adjusting gap, and sandpaper that can be pasted on for grinding carbon fiber multi-port joints.

[0011] Preferably, the carbon fiber multi-port connector includes a carbon fiber multi-port connector polished surface and a carbon fiber multi-port connector base plate.

[0012] This invention also discloses a grinding device and method for a carbon fiber multi-port joint rotary sleeve, the method being characterized by the following steps:

[0013] Step 1: Power on the system and perform a self-test. The suction platform will generate suction, and the control buttons and indicator lights will show green. Press the pneumatic suction motor start button, and the suction port on the rotary table will generate suction. Press the pneumatic suction motor stop button, and there will be no suction. Press the rotary stepper motor start button, and the rotary table will start rotating. Press the rotary stepper motor stop button, and the rotary table will stop rotating.

[0014] Step Two: Assembly. Connect the electric pistol drill to the rotary sleeve assembly via the drill chuck. Press the motor start / stop switch and observe whether the motor rotates, the drill chuck rotates, and the rotary sleeve assembly rotates concentrically. If not, re-clamp. Adjust the locking screw until the grinding surface of the carbon fiber multi-port connector contacts the rotary sleeve assembly and generates a certain moderate resistance.

[0015] Step 3: Adsorb the carbon fiber multi-port connector. Place the carbon fiber multi-port connector that needs to be polished on the adsorption port of the rotary table, adjust the position of the carbon fiber multi-port connector, and press the start button of the pneumatic adsorption motor. The carbon fiber multi-port connector will then be fixed and adsorbed.

[0016] Step 4: Grinding begins. The operator holds an electric pistol drill and intermittently presses the motor start / stop switch to rotate the rotary sleeve assembly in a reciprocating motion to grind the surface of the carbon fiber multi-port joint and adapt it to the mating rod. If it does not go in, readjust the locking screw and grind again.

[0017] Step 5: Press the start button for the rotary stepper motor, and the rotary table will start rotating. Once it reaches the desired position, press the stop button for the rotary stepper motor, and the rotary table will stop rotating. Repeat the operation process in Step 4.

[0018] Step Six: After grinding is complete, press the stop button for the pneumatic adsorption motor, remove the carbon fiber multi-port connector, and repeat Step Three to perform the grinding operation for the next carbon fiber multi-port connector.

[0019] The present invention provides a grinding device and method for a carbon fiber multi-port joint rotary sleeve, which has the following beneficial effects:

[0020] 1. This invention achieves efficient and rapid clamping and positioning of carbon fiber multi-port connectors. By using the suction port of the rotatable adsorption turntable, the carbon fiber multi-port connector is fixed and adsorbed by suction, which overcomes the problem of difficult fixation of existing carbon fiber multi-port connectors and improves the efficiency of rapid clamping of carbon fiber multi-port connectors.

[0021] 2. This invention enables grinding of any position on the carbon fiber multi-port joint. The rotary table with a rotatable adsorption turntable allows for rotation at any position angle. In addition, the rotary sleeve grinding method can achieve all-round grinding of the carbon fiber joint without dead angles, thus improving the grinding efficiency of the carbon fiber multi-port joint.

[0022] 3. This invention effectively protects against carbon fiber dust generated during the grinding of carbon fiber multi-port joints. The generated carbon fiber dust is encased inside the rotating sleeve on one hand, and can be removed by the dust collection platform on the other hand, reducing the risk of dust hazards to operators during the grinding of carbon fiber multi-port joints.
